     This summary highlights information contained elsewhere or incorporated by
reference in this prospectus. Because this is a summary, it is not complete and
does not contain all of the information that may be important to you. For a more
complete understanding of us and this offering of our common stock, we encourage

                               COBALT CORPORATION

OVERVIEW

     We are the leading managed care company in Wisconsin, offering a broad
portfolio of managed care and insurance products to employers, individuals and
government entities. We have an exclusive license to utilize the Blue Cross(R)
and Blue Shield(R) service marks in Wisconsin, giving us a unique position in
that market. As of March 31, 2002, we serviced approximately 605,000 lives in
our health insurance operations and approximately 343,000 lives in our dental
insurance programs.

     Our Blue Cross & Blue Shield United of Wisconsin subsidiary, which we refer
to as "BCBSUW," provides underwritten products, including preferred provider
organizations (PPO) and indemnity options, as well as self-funded,
administrative services only programs. Our health maintenance organizations
(HMOs) are Compcare Health Services Insurance Corporation, which we refer to as
"CompcareBlue," Valley Health Plan, Inc., which we refer to as "Valley," and
Unity Health Plans Insurance Corporation, which we refer to as "Unity." Our
CompcareBlue subsidiary operates the oldest HMO in Wisconsin.


     We offer the largest provider network in Wisconsin. All of our customers,
including HMO members, have the ability to access the leading physicians and
hospitals in their respective service areas, including Mayo Health Systems,
University Health Care and Aurora Health Care. We believe that our ability to
offer a full spectrum of products and a broad provider network to meet the needs
and objectives of a wide range of customers provides us with a competitive
advantage.


     We offer a variety of specialty managed care products, including dental,
life and disability insurance. We are one of the largest providers of dental HMO
and dental indemnity coverage in Wisconsin. We also offer workers' compensation
insurance and a variety of specialty managed care services, including cost
containment, health care electronic data interchange and receivables management
services. These specialty products and services are designed to complement our
customers' employee benefit packages. We also process Medicare claims as a
Medicare Part A fiscal intermediary and a Regional Home Health intermediary for
providers in numerous states and several U.S. territories and as a national
intermediary for the Federally Qualified Health Centers in all 50 states.

     We market our medical and dental products through a salaried sales force
located throughout Wisconsin, as well as through independent agents and brokers,
and directly to customers via the internet. By integrating the marketing of our
medical products, we are able to offer a broad range of product choices to
health care consumers. We sell our specialty managed care products and services
through a variety of distribution channels to employer groups and providers,
principally in Wisconsin.

OUR STRATEGY

     Over the past two years, we have taken certain steps that have resulted in
significant increases in profitability, including discontinuing unprofitable
business lines; repricing or terminating unprofitable customer contracts;
improving underwriting techniques and pricing products appropriately to reflect
underlying cost trends; negotiating improved terms in our provider contracts and
bolstering management in

                                        1


key areas, including in our Milwaukee market. We intend to continue to pursue
improvements in our operating results through the implementation of the
following strategies:

     - Capitalize on the Strength of the Blue Cross and Blue Shield Brands.  We
       believe that our right to the exclusive use of the Blue Cross and Blue
       Shield brands in Wisconsin gives us a significant marketing advantage,
       and we intend to continue emphasizing these brands among prospective
       customers and members. According to the Blue Cross Blue Shield
       Association, which we refer to as the "Association," the number of
       members insured by plans bearing the Blue Cross and Blue Shield brands
       has increased by approximately 26% nationwide since 1995. We further
       intend to leverage the strength of the Blue Cross and Blue Shield brands
       on a national basis by participating in the Association's BlueCard(R) PPO
       program, a network of Blue Cross and Blue Shield plans. The BlueCard PPO
       program allows us to compete with national health insurers for groups
       with employees outside of the Wisconsin market and provides our members
       the opportunity to access care while away from home.


     - Focus on Core Business.  We have made a strategic decision to focus on
       our core Blue Cross and Blue Shield branded and HMO businesses, where we
       believe significant opportunities exist for earnings growth. These
       businesses together produced over 80% of our revenues and approximately
       59% of our pre-tax operating income in the quarter ended March 31, 2002.
       On March 29, 2002, we sold our behavioral health and medical management
       subsidiary, Innovative Resource Group, LLC, for $27 million. In the
       future, we may sell other non-core specialty businesses. In addition,
       since March 1, 2002 we have reduced our investment in our former
       affiliate American Medical Security Group, Inc., or "AMSG," a small group
       and individual health insurer, from approximately 45% to approximately
       15% of AMSG's outstanding common stock, raising net proceeds of
       approximately $69 million and relieving us of a significant portion of
       our statutory capital requirement relating to AMSG.


     - Expand Operating Margins and Realize Operating Efficiencies.  We intend
       to focus on expanding operating margins in our core businesses by
       improving underwriting techniques and product design, pricing products
       appropriately to reflect underlying cost trends, discontinuing
       unprofitable businesses and customer contracts and improving provider
       arrangements. We also intend to pursue additional operating efficiencies
       through consolidation of administrative functions, including combining
       the administrative functions of BCBSUW and CompcareBlue, as well as the
       administrative functions of certain of our specialty businesses.

     - Increase Market Share.  We intend to focus on increasing market share in
       Wisconsin through an increased emphasis on our core business, the
       BlueCard PPO program and our Medicare supplement product offerings, as
       well as the introduction of new products. We expect to accomplish this by
       leveraging our customer base by cross-selling product offerings and
       pursuing opportunistic acquisitions of health insurers in Wisconsin.

RECENT DEVELOPMENTS

 SALE OF AMSG SHARES

     On June 4, 2002, BCBSUW sold 3,001,500 shares of common stock of AMSG in an
underwritten public offering, realizing net proceeds of approximately $50.8
million. This sale followed the March 22, 2002 repurchase by AMSG of 1.4 million
shares of AMSG common stock, for which AMSG paid BCBSUW a total of $18.2
million. As a result of these divestitures, during 2002 BCBSUW's ownership in
AMSG has been reduced from approximately 45% to approximately 15%.

  MANAGEMENT CHANGES

     On May 29, 2002, Thomas R. Hefty, then our President, Chairman and Chief
Executive Officer, announced that he would retire in 2002. Effective May 29,
2002, Stephen E. Bablitch, previously our

                                        2



Senior Vice President with operational responsibility for our private branded
HMOs and our Blue Cross and Blue Shield business outside the Milwaukee
metropolitan area, became our President. Michael E. Bernstein, who was elected
President of our CompcareBlue subsidiary in July 2001 and who also had
operational responsibility for our Blue Cross and Blue Shield business in the
Milwaukee metropolitan area, became our Executive Vice President. Mr. Hefty will
remain our Chairman and Chief Executive Officer until his retirement, at which
time Mr. Bablitch will become our Chairman and Chief Executive Officer and Mr.
Bernstein will become our President and Chief Operating Officer.



OUTLOOK



     As a result of favorable developments in our operations described elsewhere
in this prospectus and increasing visibility for our prospects in 2003, we are
updating our earnings guidance for 2002 and issuing earnings guidance for 2003.
Based on currently available information, for 2002 we anticipate pre-tax income
from continuing operations of approximately $49 million to $51 million, net
income from continuing operations of approximately $44 million to $46 million
and earnings per share from continuing operations of approximately $1.05 to
$1.10. These estimates assume an effective tax rate of 10% and completion of
this offering in July 2002. Based on currently available information, for 2003
we anticipate pre-tax income from continuing operations of approximately $62
million to $66 million, net income from continuing operations of approximately
$37 million to $39 million and earnings per share from continuing operations of
approximately $0.85 to $0.90. These estimates assume an effective tax rate of
40%. The increase in the tax rate for 2003 compared to 2002 reflects the
anticipated exhaustion of net operating loss carryforwards available to benefit
our operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview."



     In calculating these estimates, we exclude the results of operations of
Innovative Resource Group, which we sold in March 2002, our equity in the
operations of AMSG and gains from the sale of Innovative Resource Group and
shares of common stock of AMSG, although we include investment income from the
cash proceeds from these transactions as well as from the sale of stock in this
offering. We also assume the issuance of 2,500,000 primary shares of common
stock in this offering in July 2002.



     The foregoing estimates are forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. These estimates are not
guarantees of future performance, and we caution investors that they involve
risks and uncertainties. In making these estimates, we have assumed, among other
things, that we will continue to implement successfully our strategy of
improving our core operations, particularly by reducing loss and expense ratios.
If this or any of our other assumptions is incorrect, we may not attain our
earnings estimates. Other risks that could prevent us from attaining these
estimates are described under "Risk Factors," and we urge investors to consider
those risks carefully. We undertake no obligation to update these estimates for
any reason after the date of this prospectus.

Risk factors..................   Investing in our common stock involves
                                 significant risks. See "Risk Factors."

     We calculated the number of our outstanding shares based upon the number of
shares outstanding as of June 12, 2002. We exclude from this number a total of
4,051,066 shares issuable upon exercise of options granted by us under our
equity incentive plan as of such date at a weighted average exercise price of
$8.02 per share, of which approximately 1,886,466 shares at a weighted average
exercise price of $7.92 per share were exercisable as of that date. We have also
excluded from the number of outstanding shares a total of 7,949,904 shares owned
by BCBSUW and treated as treasury shares.


     The Foundation has agreed to sell an additional 1,125,000 shares if the
underwriters exercise in full their over-allotment option, which we describe in
"Underwriting." Unless the context otherwise requires, the information presented
in this prospectus assumes that this option will not be exercised.

               SUMMARY CONSOLIDATED FINANCIAL AND OPERATING DATA

     We were formed in March 2001 as the successor to substantially all of the
operations of BCBSUW and United Wisconsin Services, which we refer to as "UWS."
Under accounting principles generally accepted in the United States, our
financial statements reflect the business and assets of BCBSUW, without UWS, for
periods through March 31, 2001, and the combined businesses of BCBSUW and UWS
for periods after that date. This presentation limits the comparability of the
financial and operating data set forth below. See "Background of the Company"
and "Selected Consolidated Financial and Operating Data" for more information.

                                  RISK FACTORS

     An investment in our common stock involves risk. You should carefully
consider the risks we describe below before deciding to invest our common stock.
The market price of our common stock could decline due to any of these risks, in
which case you could lose all or part of your investment. In assessing these
risks, you should also refer to the other information included and incorporated
by reference in this prospectus, including our consolidated financial statements
beginning on page F-1.

  OUR INSURANCE SUBSIDIARIES ARE SUBJECT TO MINIMUM CAPITAL REQUIREMENTS. OUR
  FAILURE TO MEET THESE REQUIREMENTS COULD SUBJECT US TO REGULATORY ACTIONS OR
  RESULT IN THE TERMINATION OF OUR BLUE CROSS AND BLUE SHIELD LICENSE
  AGREEMENTS.


     Our insurance subsidiaries are subject to minimum capital requirements
imposed under the laws of the State of Wisconsin. These laws include minimum
capital requirements calculated under a State of Wisconsin prescribed compulsory
and security surplus computation, which establishes minimum capital based upon a
percentage of underwritten premiums, with the applicable percentage determined
by line of business. Wisconsin insurance laws also include minimum capital
requirements based on the Risk Based Capital for Insurers Model Act adopted by
the National Association of Insurance Commissioners, or "NAIC," and require our
insurance subsidiaries to report their results of risk-based capital
calculations to the state insurance departments and the NAIC. Any failure by one
of our insurance subsidiaries to meet the minimum capital requirements imposed
under Wisconsin law will subject it to corrective action, including requiring
the adoption of a comprehensive financial plan, examination and the issuance of
a corrective order by the Office of the Commissioner of Insurance of the State
of Wisconsin, which we refer to as the "OCI," revocation of its license to sell
insurance products in Wisconsin, or placing the subsidiary under state
regulatory control. See "Business -- Regulation -- Capital Requirements."


     At the request of the OCI, we prepared a plan of action in early 2002 for
strengthening the capital position of our insurance subsidiaries. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Management's Plan." Our insurance subsidiaries are currently in
compliance with the minimum capital requirements imposed under Wisconsin law,
calculated as required by the OCI.


     In addition, the Association imposes certain financial and service
performance standards on Cobalt, BCBSUW and CompcareBlue, including capital
requirements based on risk-based capital. Our right to use the Blue Cross and
Blue Shield brands in our service area is derived from a license agreement we
have with the Association. The Association's capital requirements are generally
more stringent than those imposed under Wisconsin law. The Association has
termination rights if our Blue Cross and Blue Shield branded licensees' capital
falls below the lowest of three capital thresholds established by the
Association. Cobalt, BCBSUW and CompcareBlue have fallen below two of these
capital thresholds. As a result, the Association has included Cobalt, BCBSUW and
CompcareBlue in its Plan Performance Response Monitoring Process, or "PPRMP,"
which entails a variety of financial monitoring and reporting and asset escrow
requirements, among other measures. Currently, all of our Blue Cross and Blue
Shield licensees maintain risk-based capital in excess of the lowest of the
three risk-based capital levels established by the Association. See
"Business -- Blue Cross and Blue Shield Licenses."



     Any new minimum capital requirements adopted in the future by the
Association or by the OCI may require us to increase our capital levels, which
we may not be able to do.


  OUR BLUE CROSS AND BLUE SHIELD LICENSE AGREEMENTS COULD TERMINATE UPON THE
  OCCURRENCE OF EVENTS SPECIFIED IN THE LICENSE AGREEMENTS, AND TERMINATION
  WOULD SIGNIFICANTLY HARM OUR BUSINESS.

     Under license agreements with the Association, we have the right to use the
Blue Cross and Blue Shield names and service marks in our Blue Cross and Blue
Shield service area and to participate in the BlueCard Program. We believe that
our exclusive right to use the Blue Cross and Blue Shield names and service
marks provides us with an important marketing advantage in our service area.
Loss of these licenses would significantly harm our ability to compete in our
markets and subject us to a significant monetary penalty to the Association.
                                        7


     The Association could terminate our license agreements if we do not satisfy
its financial and service performance requirements or if other events described
in the license agreements, some of which are outside of our control, occur.
These events include, but are not limited to:

     - failure to meet capital and liquidity requirements of the Association;

     - violation of the ownership limitations contained in our Amended and
       Restated Articles of Incorporation and described in this prospectus;

     - termination of the voting trust and divestiture agreement before the
       Foundation's ownership of our common stock falls to less than 5%;

     - the acquisition of our company without the prior consent of a majority of
       the other disinterested licensees of the Association and a majority of
       the then current weighted vote of the other disinterested licensees of
       the Association;

     - failure by the Foundation to divest its shares of our common stock by the
       deadlines specified by the voting trust and divestiture agreement;


     - a determination by the Association that fewer than 80% of our directors
       are independent; and


     - failure to brand medical and dental business as required by the
       Association.

     Our Amended and Restated Articles of Incorporation include ownership
limitations required by the Association. Although we believe that these
limitations are enforceable under Wisconsin law for a corporation like ours, we
are not aware of any case in which a court has specifically addressed this
issue. If one of our shareholders violates the ownership limitations and
disputes their enforceability and a court does not enforce the provisions of our
Amended and Restated Articles of Incorporation, we could lose our licenses to
use the Blue Cross and Blue Shield names and service marks.

  WE MAY NOT BE ABLE TO MAINTAIN PROFITABILITY, AND OUR QUARTERLY OPERATING
  RESULTS MAY FLUCTUATE SIGNIFICANTLY.


     Although we reported net income in the first quarter of 2002, we
experienced net losses in each of the years ended December 31, 1999, 2000 and
2001. During this time period, we experienced operational difficulties that led
to these losses and corresponding decreases in our capital. In an effort to
remedy these difficulties, we have devoted significant resources to improving
our core operations while divesting non-core assets. Nevertheless, we cannot
assure you that we will be able to achieve sustained profitability. If we incur
additional losses, we could have difficulty satisfying our obligations to the
OCI or implementing our related action plan. In addition, our relationship with
the Association could be adversely affected and our stock price would decline.
Moreover, our quarterly results of operations could fluctuate significantly due
to a variety of factors, including steps we are taking to enhance our core
operations such as exiting unprofitable businesses, as well as from inherent
aspects of our business, such as the need to make current estimates of future
claims. These fluctuations could adversely affect the price or liquidity of our
common stock.


 OUR RESULTS OF OPERATIONS WILL BE ADVERSELY AFFECTED IF WE ARE UNABLE TO
 INCREASE PREMIUMS TO OFFSET INCREASES IN OUR HEALTH CARE COSTS.

     Health care costs in recent years have generally increased substantially
year-over-year, and we expect that they will continue to do so in the future.
Our results of operations depend on our ability to increase premiums to offset
increases in our health care costs. Although we attempt to base the premiums we
charge on our estimate of future health care costs, we may not be able to charge
adequate premiums as a result of competition, government regulations and other
factors. Our results of operations could be adversely affected if we are unable
to set premium rates at appropriate levels or adjust premium rates in the event
our health care costs increase.

                                        8


 AN ONGOING REDUCTION IN THE NUMBER OF SUBSCRIBERS TO OUR HEALTH CARE PROGRAMS
 MAY REDUCE OUR REVENUE AND PROFITABILITY.

     Overall membership in our health benefits plans has decreased substantially
recently, in large part due to our efforts to eliminate unprofitable business.
We expect that this decline will continue over the near term. An ongoing
reduction in the number of subscribers to our health care programs could
adversely affect our financial position, results of operations and cash flows.
Factors that could contribute to the loss of membership include:

     - failure to obtain new customers and failure to retain or voluntarily
       terminating existing customers;

     - premium increases and benefit changes;

     - reduction in our provider network;

     - our exit from business lines or markets;


     - reductions in work force by existing customers; and


     - negative publicity or news coverage about us or other managed care
       companies.

 OUR RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED IF WE ARE UNABLE TO
 ACCURATELY ESTIMATE AND CONTROL FUTURE HEALTH CARE COSTS.

     Most of the premium revenue we receive is based upon rates set before we
deliver services. As a result, our ability to price contracts profitably largely
depends on our ability to accurately estimate and then control future health
care costs. Factors that may cause health care costs to exceed our estimates
include:

     - an increase in the cost of health care services and supplies, including
       pharmaceuticals;

     - higher than expected utilization of health care services by our insured
       members;

     - periodic renegotiation of contracts with hospitals, physicians and other
       providers;

     - the occurrence of catastrophes or epidemics;

     - changes in the demographics of our members and medical trends affecting
       them;

     - new mandated benefits or other regulatory changes that increase our
       costs; and

     - other unforeseen occurrences.

     In addition to actual benefits paid, our medical and other benefits expense
for any period includes our estimate of reported and unreported claims and
related expenses for the period. The reserves we establish for these expenses
are based upon assumptions concerning a number of factors, including trends in
health care costs, our underwriting criteria, enrollment in our plans, expenses,
general economic conditions and other factors. Actual experience will likely
differ from assumed experience, and to the extent the actual claims experience
is less favorable than estimated based on our underlying assumptions, our
incurred losses would increase and future earnings could be adversely affected.

     Our medical, workers' compensation, and other benefit expenses include
estimates of expenses incurred but not yet reported to us, or "IBNR." We
estimate our IBNR expenses based on a number of factors, including prior claims
experience, maturity of markets, complexity of products and stability of
provider networks.


     We make adjustments, if necessary, to benefit expenses in the period during
which the actual claim costs are ultimately determined or when criteria used to
estimate IBNR change. We utilize the services of independent actuaries to
calculate and review the adequacy of our benefit liabilities, in addition to
using internal resources. We cannot be sure that our IBNR estimates are adequate
or that adjustments to such IBNR estimates will not harm our results of
operations. Further, our inability to accurately estimate IBNR


                                        9


may also affect our ability to take timely corrective actions, further
exacerbating the negative impact on our results.

     Although we maintain reinsurance to protect us against severe or
catastrophic medical claims, we cannot assure you that such reinsurance coverage
will be adequate or available in the future or that the cost of such reinsurance
will not limit our ability to obtain it.

 OUR PROFITABILITY WILL DECLINE IF WE ARE UNABLE TO MAINTAIN OUR RELATIONSHIPS
 WITH CERTAIN SIGNIFICANT PROVIDER GROUPS OR IF WE ARE UNABLE TO ENTER INTO
 AGREEMENTS WITH ADDITIONAL PROVIDERS ON FAVORABLE TERMS.

     Our Unity and Valley HMOs rely in large part on three separate health care
provider systems for the provision of health care services to their members. If
one or more of our relationships with these systems were to be terminated, we
would be adversely affected. See "Business -- Our Provider Network."

     Our profitability depends upon our ability to contract on cost-effective
terms with hospitals, physicians and other health care providers. If we fail to
obtain health care provider contracts, or renew those we have, on favorable
terms, we may lose some of our members or incur higher medical costs. In
addition, our inability to contract with providers, or the inability of
providers to provide adequate care, could significantly harm us.

 COMPETITION IN OUR INDUSTRY MAY DECREASE OUR PROFITABILITY.

     We operate in a highly competitive environment which may affect our ability
to maintain or increase our membership or premium rates or to contract with
providers on attractive terms. We face competition from other managed care
companies, hospitals, health care facilities and other health care providers,
some of which have substantially greater financial and other resources than we
have.

     We believe there are no significant impediments facing potential
competitors who wish to enter the markets we serve. As a result, the entry of
new competitors into our markets can occur relatively easily, which affords our
customers significant flexibility in moving to other managed care providers and
which creates alternatives for participants in our provider networks. Our
managed care operations may encounter competition from companies with broader or
narrower geographical markets, each of which could provide a competitor with
specific competitive advantages, such as greater cost control, lower prices or
greater market share. Our financial condition or results of operations may be
adversely affected by significant premium decreases by any major competitor or
by any other limitation on our ability to maintain or increase our membership or
premium levels.

     In certain markets, we compete with organizations which have a substantial
market share. In other markets, competing health plans may be owned by
providers. Portions of the Wisconsin market are dominated by a relatively small
number of provider-owned health plans, with a large influence on the markets in
which we compete. Organizations with sizable market share or provider-owned
plans may be able to obtain favorable financial arrangements from health care
providers that are not available to us. Without such arrangements, we may not be
able to compete effectively in such markets.

     In addition, legislation is currently pending in Congress that is intended
to increase competition for government contracts for processing claims for the
Medicare program. Our United Government Services subsidiary serves as a fiscal
intermediary for the Medicare program. If this legislation is adopted, our
ability to compete effectively for Medicare contracts may suffer.

 OUR BUSINESS IS DEPENDENT IN PART ON THE SERVICE OF NON-EXCLUSIVE INDEPENDENT
 AGENTS AND BROKERS WHO MAY REFER THEIR BUSINESS TO OUR COMPETITORS.

     We depend in part on the services of independent agents and brokers in the
marketing of health care plans, particularly to individual and small employer
group members. Independent agents and brokers are typically not exclusively
dedicated to one company and market health care products of our competitors. In
addition, we face intense competition for the services and allegiance of
independent agents and brokers.

These persons may choose to direct business to other managed care companies or
may direct less desirable sales prospects to us.

 THE HEALTH BENEFITS INDUSTRY IS SUBJECT TO NEGATIVE PUBLICITY, WHICH CAN
 ADVERSELY AFFECT OUR PROFITABILITY.

     The health benefits industry is subject to negative publicity. Negative
publicity may result in increased regulation and legislative review of industry
practices, which may further increase our costs of doing business and adversely
affect our profitability by:

     - adversely affecting our ability to market our products and services;

     - requiring us to change our products and services; or

     - increasing the regulatory burdens under which we operate.

     In addition, as long as we use the Blue Cross and Blue Shield names and
marks in marketing our health benefits products and services, any negative
publicity concerning the Association or other Association licensees may
adversely affect us and the sale of our health benefits products and services.

 FAILURE TO PROPERLY MAINTAIN THE INTEGRITY OF OUR PROPRIETARY INFORMATION AND
 INFORMATION SYSTEMS COULD RESULT IN THE LOSS OF CUSTOMERS OR DECREASE IN OUR
 PROFITABILITY.


     Our business depends in part on our ability to maintain, or access through
outsourcing arrangements with third parties, information systems and to ensure
the continued integrity of our proprietary information. Moreover, the
collection, dissemination and use of patient data is the subject of national and
state legislation. If we do not maintain or access effective and efficient
information systems, then we could experience:


     - inadequate information on which to base pricing and underwriting
       decisions;

     - the loss of existing customers;

     - difficulty in attracting new customers;

     - customer and provider disputes;

     - regulatory problems;

     - increases in administrative expenses; or

     - other adverse consequences.

     We use third party service providers for claims processing and enrollment
functions, and therefore have only limited control over data management
associated with these functions.

 HEALTH CARE DEVELOPMENTS OR AN ECONOMIC DOWNTURN IN WISCONSIN MAY HARM OUR
 RESULTS.

     We conduct business primarily within the State of Wisconsin, and a large
proportion of our membership is in the Milwaukee metropolitan area. Therefore,
our business may be more sensitive to local or state conditions, such as pricing
dynamics, health care developments or general economic conditions, than
organizations servicing larger, more diverse markets. For example, national
competitors can subsidize losses in the Wisconsin market with profits from other
markets in which they operate. We may be competitively disadvantaged, or
otherwise harmed, by our Wisconsin focus.

 OUR INVESTMENT PORTFOLIO IS SUBJECT TO VARYING ECONOMIC AND MARKET CONDITIONS,
 AS WELL AS REGULATION.

     We depend on our investment portfolio as a source of liquidity to pay
medical claims and fund other expenses. Returns on our investment portfolio also
have historically contributed significantly to our net income. Our investment
portfolio consists primarily of fixed maturity securities, short-term
investments, indexed mutual funds, and other investments. The market value of
our investments varies from time to time depending on factors relating
specifically to the issuers of the securities as well as to more general
                                        11


factors such as prevailing interest rates and economic and market conditions.
Fluctuations in the market value of our investment portfolio could adversely
affect our liquidity. These fluctuations could also reduce our investment return
or result in losses when we sell investments to fund our cash needs, which could
adversely affect our overall profitability.

     Our regulated subsidiaries are subject to state laws and regulations that
require diversification of their investment portfolios and limit the amount of
investments in certain investment categories. While we have adopted an
investment policy intended to facilitate compliance with statutory and
regulatory requirements, our failure to comply with these laws and regulations
might cause investments exceeding regulatory limitations to be treated as
non-admitted assets for purposes of measuring statutory surplus and risk-based
capital, and, in some instances, require the sale of those investments. For more
information on our investment portfolio, see Note 5 of Notes to Consolidated
Financial Statements.

 A DOWNGRADE IN OUR SUBSIDIARIES' RATINGS MAY ADVERSELY AFFECT OUR BUSINESS,
 FINANCIAL CONDITION AND RESULTS OF OPERATIONS.


     In February 2002, A.M. Best downgraded its rating of our insurance
subsidiaries to B+ "Very Good." The A.M. Best rating principally impacts our
ability to underwrite workers' compensation business. When the rating of United
Wisconsin Insurance Company, which underwrites our workers' compensation
product, was downgraded from A- "Excellent" to B++ "Very Good" in June 2001, we
arranged with a reinsurer to use its insurance company, which had an A+
"Superior" rating by A.M. Best, to serve as underwriter for customers that
required the higher rating for their workers' compensation coverage. In exchange
for the use of the reinsurer's license, we were required to increase the portion
of the workers compensation business ceded to the underwriter from 20% to 35%.
Any future downgrade of the rating of our subsidiaries, should one occur, or our
inability to access an "A" rated underwriter on acceptable terms, could
negatively impact our ability to underwrite workers' compensation business.


  WE CONDUCT BUSINESS IN A HEAVILY REGULATED INDUSTRY, AND CHANGES IN
  REGULATIONS OR VIOLATIONS OF REGULATIONS COULD SIGNIFICANTLY HARM US.

     Our business is heavily regulated on federal, state and local levels as we
discuss under "Business -- Regulation." For example, we need to obtain and
maintain regulatory approvals to market many of our products. Delays in
obtaining or failure to obtain or maintain these approvals could significantly
harm us.

     We are also subject to various governmental reviews, audits and
investigations designed to monitor our compliance with applicable rules and
regulations. Any adverse investigation, audit results or sanctions could result
in:

     - damage to our reputation in various markets;

     - increased difficulty in selling our products and services;

     - loss of a license to act as an insurer or HMO or to otherwise provide a
       service;

     - loss of the right to participate in various federal programs, including
       the Medicare supplement programs; or

     - imposition of fines, penalties and other sanctions.

     Legislation or other regulatory reform that increases the regulatory
requirements imposed on us may significantly harm our business or results of
operations in the future. Legislative or regulatory changes that could
significantly harm us and our subsidiaries include:

     - legislation that holds insurance companies, HMOs or managed care
       companies liable for adverse consequences of medical decisions;

     - limitations on premium levels;

     - increases in minimum capital, reserves and other financial viability
       requirements;

                                        12


     - impositions of fines or other penalties for the failure to promptly pay
       claims;

     - prohibitions or limitations on provider financial incentives and provider
       risk-sharing arrangements;


     - imposition of more stringent standards of review of our coverage
       determinations;


     - new benefit mandates; and

     - limitations on the ability to manage care and utilization due to "any
       willing provider" and direct access laws that limit or eliminate product
       features that encourage members to seek services from contracted
       providers or through referral by a primary care provider.


     For example, Congress currently is considering patient protection
legislation, commonly known as Patients' Bill of Rights legislation, which
incorporates some of the provisions described above. We cannot predict the
impact of this legislation, if adopted, on our business.


     A portion of our revenues relate to Medicare supplement programs. Changes
in these programs, particularly changes affecting enrollment or changes in
premium payment or reimbursement levels, could significantly harm our business
and decrease our profitability.

 AS A MEDICARE FISCAL INTERMEDIARY, OUR UNITED GOVERNMENT SERVICES SUBSIDIARY IS
 SUBJECT TO COMPLEX REGULATIONS. IF IT FAILS TO COMPLY WITH THESE REGULATIONS,
 IT MAY BE EXPOSED TO CRIMINAL SANCTIONS AND SIGNIFICANT CIVIL PENALTIES.

     Our United Government Services subsidiary serves as a fiscal intermediary
for the Medicare program. The laws and regulations governing fiscal
intermediaries for the Medicare program are complex and subject to
interpretation and can expose a fiscal intermediary to penalties for
non-compliance. Fiscal intermediaries may be subject to criminal fines, civil
penalties or other sanctions as a result of periodic audits or reviews. Other
companies in this business have recently been subject to significant fines and
censures for non-compliance. While we believe that we are in compliance in all
material respects with the regulations governing fiscal intermediaries, we
cannot assure you of this.

 COMPLIANCE WITH PRIVACY LAWS COULD ADVERSELY AFFECT OUR BUSINESS AND RESULTS OF
 OPERATIONS.

     The collection, dissemination and use of patient data by our businesses is
regulated at the federal, state and local level. The Health Insurance
Portability and Accountability Act of 1996, or "HIPAA," for example, imposes
significant new requirements relating to maintaining the privacy of medical
information. The government published regulations to implement these provisions
in December 2000 and proposed revisions to these regulations in March 2002. As
both a health plan and a health clearinghouse, we must be in compliance with
these regulations by April 2003. The law is far-reaching and complex, and proper
interpretation and practice under the law continue to evolve. Consequently, our
efforts to measure, monitor and adjust our business practices to comply with the
law are ongoing. Failure to comply with this law could subject us to civil and
criminal penalties. Because these regulations and other similar federal, state
and local laws and regulations continue to evolve, we cannot guarantee that
compliance will not be costly or cause us to change our operations
significantly.

 WE ARE SUBJECT TO LITIGATION, INCLUDING LITIGATION BASED ON NEW OR EVOLVING
 LEGAL THEORIES, THAT COULD SIGNIFICANTLY AFFECT OUR RESULTS OF OPERATIONS.

     Due to the nature of our business, we are subject to a variety of legal
actions relating to our business operations, including:

     - disputes over coverage or claims adjudication;

     - vicarious liability for medical malpractice claims;

     - disputes with our providers or agents over compensation and termination
       of contracts;

                                        13


     - disputes related to our non-risk business, including actions alleging
       breach of fiduciary duties, claim administration errors or other
       violations of federal or state laws; and

     - customer audits of our compliance with our plan obligations.

     In addition, plaintiffs continue to bring new types of legal claims against
managed care companies. Recent court decisions and legislative activity increase
our exposure to these types of claims. In some cases, plaintiffs may seek class
action status and substantial economic, non-economic or punitive damages. The
loss of even one of these claims, if it resulted in a significant damage award,
could have a significant adverse effect on our financial condition or results of
operations. This risk of potential liability may make reasonable settlements of
claims more difficult to obtain. We cannot determine with any certainty what new
theories of recovery may evolve or what their impact may be on the managed care
industry in general or on us in particular. We believe we have made adequate
reserves in our financial statements against all litigation known to us, but we
cannot be certain our estimates of probable outcomes of such litigation will
prove to be accurate.

     We currently have, and expect to maintain, liability insurance coverage for
some of the potential legal liabilities we may incur. Potential liabilities that
we incur may not, however, be covered by insurance, our insurers may dispute
coverage, our insurers may be unable to meet their obligations or the amount of
our insurance coverage may be inadequate. We cannot assure you that we will be
able to obtain insurance coverage in the future, or that insurance will continue
to be available on a cost effective basis, if at all.

     We are also subject to other types of claims and potential claims, which
could have a material adverse effect on our financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources" and "Business --
Management Information Systems."

  AS A HOLDING COMPANY, WE ARE DEPENDENT ON DIVIDENDS FROM OUR SUBSIDIARIES.

     We are a holding company whose assets consist largely of the outstanding
shares of common stock of our subsidiaries. As a holding company, we depend on
dividends from our insurance company subsidiaries. Our insurance subsidiaries
are currently prohibited from paying dividends to us without the approval of the
OCI. Our ability to pay our shareholders dividends in the future and meet our
obligations, including paying operating expenses and debt service on our
outstanding and future indebtedness, will depend upon the receipt of dividends
from our subsidiaries. An inability of our subsidiaries to pay dividends in the
future in an amount sufficient for us to meet our financial obligations may
materially adversely affect our business, financial condition and results of
operations.

 PROVISIONS IN OUR AMENDED AND RESTATED ARTICLES OF INCORPORATION AND BYLAWS AND
 WISCONSIN LAW MAY PREVENT US FROM BEING SOLD TO A THIRD PARTY, AND MAY LIMIT OR
 ELIMINATE INCREASES IN STOCK PRICE BASED ON "TAKEOVER" SPECULATION.

     Our Amended and Restated Articles of Incorporation and Bylaws include
provisions required by the Association for its for-profit licensees, which the
Association designed to protect the independence of its for-profit licensees
from any single shareholder. These provisions include the following:

     - ownership limitations that prohibit institutional investors from owning
       10% or more of the voting power of our outstanding securities and
       prohibit other investors from owning 5% or more of the voting power of
       our outstanding securities; and

     - initially, at least 80% of our directors must be independent directors
       who are not affiliated or associated with the Foundation or any
       shareholder that owns our shares in excess of the ownership limits.

     These provisions may make it more difficult for a third party to acquire us
in a transaction that our board of directors has not negotiated or approved but
in which our shareholders may receive a premium for their shares. Also, these
provisions can deter a party from acquiring a significant ownership position in

                                        14


us prior to submitting an offer to our board of directors, and, as a result, our
common stock may trade at lower prices relative to other companies that do not
have similar ownership limitations in their charter documents.

     In addition, Wisconsin insurance law prohibits any person from acquiring
control of us, and thus indirect control of our insurance subsidiaries, without
the prior approval of the OCI. Any purchaser of 10% or more of the voting
securities of a corporation is presumed to have acquired control of the
corporation unless the OCI determines otherwise.


 REGISTRATION RIGHTS OF THE FOUNDATION AND THE OVERSIGHT OF THE OCI MAY INHIBIT
 OUR ABILITY TO RAISE FUNDS THROUGH EQUITY OFFERINGS.


     In order to take advantage of acquisition and other investment
opportunities that may arise in the future, we may desire the flexibility to
raise funds quickly by selling our common stock in the equity markets. The
Registration Rights Agreement that we entered into with the Foundation in the
Combination (which we describe in "Background of the Company") could limit or
make more difficult our ability to raise funds through equity offerings.


     In addition, under the OCI order issued in connection with the Combination,
we are required to obtain the approval of the OCI prior to any issuance of our
common stock. This approval is required until the OCI determines that its
oversight is no longer necessary to protect the Foundation against improper
dilution of its equity interest.


     Our failure to raise additional equity capital when required could:

     - restrict our future growth, both internally and through acquisitions;

     - inhibit our ability to invest in technology and other products and
       services that we may need;

     - adversely affect our ability to compete in the markets we serve; and


     - restrict the availability of capital for our subsidiaries.


 OUR DIRECTORS ARE GENERALLY ABLE TO CONTROL THE OUTCOME OF MATTERS, OTHER THAN
 CHANGE OF CONTROL PROPOSALS, THAT ARE SUBMITTED TO OUR SHAREHOLDERS FOR A VOTE
 AS LONG AS THE FOUNDATION BENEFICIALLY OWNS A SUBSTANTIAL PERCENTAGE OF THE
 OUTSTANDING SHARES OF OUR COMMON STOCK.

     The Foundation beneficially owns approximately 77% of the outstanding
shares of our common stock prior to completion of this offering. The Foundation
has placed all of its shares in a voting trust for a trustee to vote and dispose
of under the terms of the Voting Trust and Divestiture Agreement.

     The trustee of the voting trust must, as a general matter, vote all of the
Foundation's shares held in the voting trust as directed by a majority of our
independent directors and a majority of all of our directors on all proposals or
matters that may come before our shareholders, except for matters relating to
proposed combination and sale transactions if our shareholders will not own a
majority of the shares of the resulting company. Thus, except for votes relating
to business combination or sale transactions, so long as the Foundation
beneficially owns a number of shares sufficient to control the outcome of a
shareholder vote and more than 20% of our outstanding shares, our board of
directors will be able to control the outcome of most matters brought before our
shareholders for a vote. In addition, so long as the Foundation beneficially
owns more than 20% of our outstanding shares, any amendment to the Articles of
Incorporation or Bylaws requires approval by the OCI.

     In any election of directors, the trustee of the voting trust must vote the
Foundation's shares in favor of each nominee approved by a majority of our
directors who are deemed to be "independent" under the Association's standards
and a majority of all of our directors. As a result, our directors will likely
be able to ensure their re-election and designate their successors for as long
as the Foundation owns a substantial number of shares of our common stock.

                                        15


 WE WILL NOT BE ABLE TO SELL OR MERGE WITHOUT THE APPROVAL OF THE FOUNDATION AS
 LONG AS THE FOUNDATION BENEFICIALLY OWNS 50% OR MORE OF THE OUTSTANDING SHARES
 OF OUR COMMON STOCK.

     Any acquisition of Cobalt will require the approval of our board of
directors and the holders of a majority of the shares of our common stock. As
long as the Foundation beneficially owns more than 50% of our common stock, it
will be able, by itself, to block any such proposed transaction even if our
board of directors and other shareholders would otherwise favor the transaction.
In addition, for so long as the Foundation beneficially owns at least 20% of our
outstanding shares, we must consult with the Foundation prior to soliciting, or
upon receiving, a business combination proposal which, if consummated, would
result in our then existing shareholders owning less than a majority of the
outstanding shares of the resulting company. The Foundation is expected to vote
its shares of our common stock on proposed merger and sale transactions based
upon its best interests. The interests of the Foundation in a merger or sale
transaction may be different from the interests of other shareholders.

  TRADING VOLUME FOR OUR COMMON STOCK HAS BEEN LIMITED, AND SIGNIFICANT SALES OF
  OUR COMMON STOCK BY THE FOUNDATION, OR THE EXPECTATION OF THESE SALES, COULD
  CAUSE OUR STOCK PRICE TO FALL.

     From the completion of the Combination on March 23, 2001 through June 12,
2002, the average daily trading volume of our common stock was 37,345 shares per
day. Given the limited trading volume of our common stock, significant sales of
our common stock by the Foundation, or the expectation of these sales, could
cause our stock price to fall.


     The Foundation is obligated to reduce its ownership of our common stock to
certain levels by specified dates. Assuming the sale of 5,000,000 shares by the
Foundation and the sale of 2,500,000 shares by us in this offering and assuming
that we do not issue any additional shares of our common stock after this
offering, the Foundation is required to sell approximately 4.5 million
additional shares of our common stock prior to March 23, 2004, subject to a
possible one-year extension, and after that it must sell a total of
approximately 13 million additional shares of our common stock prior to March
23, 2006, subject to a possible two-year extension. If the Foundation fails to
meet the divestiture requirements described above, we are entitled to arrange
for the sale of the Foundation's shares. The Foundation has the right to require
us to periodically file registration statements covering sales of stock by the
Foundation. As described under "Agreements with the Foundation -- Certain
Agreements Executed in Connection with the Combination -- Registration Rights
Agreement," the Foundation is entitled to demand a registration beginning 120
days after we have effected the registration of our shares in this offering.


  OUR STOCK AND THE STOCKS OF OTHER COMPANIES IN THE HEALTH CARE INDUSTRY ARE
  SUBJECT TO STOCK PRICE AND TRADING VOLUME VOLATILITY.

     From time to time, the stock price and the number of shares traded of
companies in the health care industry experience periods of significant
volatility. Both company-specific issues and developments generally in the
health care industry and in the regulatory environment may cause this
volatility. Our stock price may fluctuate in response to a number of events and
factors, including:

     - quarterly variations in operating results;

     - changes in financial estimates and recommendations by securities
       analysts;

     - operating and stock price performance of other companies that investors
       may deem comparable;

     - news reports by or relating to us or our competitors or relating to
       trends in our markets;

     - acquisitions and financings in our industry; and

     - sales of stock by insiders.

                                        16


                           FORWARD-LOOKING STATEMENTS

     This prospectus contains and incorporates by reference forward-looking
statements that involve risks and uncertainties. We intend these forward-looking
statements to be covered by the safe harbor provisions for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995,
and we are including this statement for purposes of those safe harbor
provisions. These forward-looking statements are often accompanied by words such
as "believe," "anticipate," "plan," "expect," "estimate," "intend," "seek,"
"goal," "may," "will," "could" and similar expressions. These statements
include, without limitation, statements about our plans and expectations for
improving our capital position and operating results, our market opportunities,
our growth strategies, competition, expected activities and future acquisitions
and investments and the adequacy of our available cash resources. These
statements may be found in the sections of this prospectus entitled "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and "Business." We caution investors that
matters subject to forward-looking statements involve risks and uncertainties,
including economic, regulatory, competitive and other factors that may affect
our business. These statements are not guarantees of future performance. We
undertake no obligation to publicly update any forward-looking statements for
any reason after the date of this prospectus.

     Our actual results may differ from projections or estimates due to a
variety of important factors. Our results of operations and projections of
future earnings depend in large part on accurately predicting and effectively
managing our business. A variety of factors may in the future affect our
operating results, including:

     - loss of existing customer relationships and an ongoing decline in
       membership;

     - competition;

     - changes in health care practices;

     - changes in federal or state laws and regulations or their
       interpretations;

     - medical cost inflation;

     - provider contract changes;

     - new technologies;

     - changes in our management;

     - government-imposed surcharges;

     - taxes or assessments;

     - major epidemics;

     - disasters; and

     - numerous other factors affecting the delivery and cost of health care,
       such as major health care providers' inability to maintain their
       operations.

     Due to these factors and risks, no assurance can be given with respect to
our future premium levels or our ability to control our future medical costs.

                                        17


                                USE OF PROCEEDS


     We will receive net proceeds of approximately $53.4 million from our sale
of 2,500,000 shares of our common stock in this offering, assuming a public
offering price of $22.80 per share and after deducting underwriting discounts
and estimated offering expenses that we will pay. We will not receive any
proceeds from the sale of shares of our common stock by the Foundation in this
offering.



     We intend to use approximately $22.6 million of the net proceeds to us from
this offering to repay a note in that amount issued by us to one of our
insurance company subsidiaries, United Wisconsin Insurance Company, or "UWIC."
This intercompany indebtedness is due September 30, 2002 and bears interest at
the rate of 7.38% per annum. Repayment of this debt will improve our capital
position. Because UWIC is part of our consolidated group, neither this note nor
its repayment are or will be reflected in our balance sheet or results of
operations. We expect UWIC will use the proceeds received from repayment of the
note for general corporate purposes.



     We also intend to use the net proceeds to repay outstanding third-party
indebtedness incurred by our holding company. We currently owe $6.0 million of
such indebtedness under a term note issued to a commercial lender. This note has
an adjustable rate of interest equal to LIBOR plus 1.5%, with payment of
principal and interest due in quarterly installments beginning June 30, 2002 and
ending June 30, 2003.


     We intend to use the balance of the net proceeds for working capital and
general corporate purposes. Pending any such use, we intend to invest our
proceeds in investment grade securities in accordance with the corporate
policies applicable to our investment portfolios.

                                        18


                          PRICE RANGE OF COMMON STOCK

     Our common stock is traded on the New York Stock Exchange under the symbol

</Table>



     As of July 1, 2002, there were 204 shareholders of record of our common
stock. Based on information obtained from our transfer agent and from
participants in security position listings and otherwise, we have reason to
believe there are more than 1,700 beneficial owners of shares of our common
stock.


                                DIVIDEND POLICY

     We do not currently pay cash dividends and we do not plan to declare or pay
any dividends in the foreseeable future, but will instead retain cash for
working capital needs, for possible acquisitions, to reduce outstanding debt or
for other corporate purposes. Our ability to pay dividends to our shareholders
in the future will depend primarily upon the receipt of dividends from our
insurance subsidiaries. Currently, our insurance subsidiaries are prohibited
from paying dividends to us without the approval of the OCI.

                                 CAPITALIZATION


     The following table sets forth our actual capitalization as of March 31,
2002 and our capitalization as of March 31, 2002 adjusted to reflect our sale of
2,500,000 shares of common stock in this offering, at an assumed public offering
price of $22.80 per share, and the application of the estimated net proceeds as
if this offering had been completed on March 31, 2002.


     We will not receive any proceeds from the Foundation's sale of our common
stock. You should read this information in conjunction with our consolidated
financial statements beginning on page F-1, including the notes to our
consolidated financial statements.

                                    DILUTION

     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma net tangible book value per share of our common
stock after this offering. We calculate net tangible book value per share by
calculating the total assets less intangible assets and total liabilities, and
dividing it by the number of outstanding shares of common stock.


     As of March 31, 2002, we had 40,666,385 shares of common stock outstanding.
Our net tangible book value as of March 31, 2002 was $140,560,000, or
approximately $3.46 per share of common stock. After giving effect to our sale
of 2,500,000 shares of common stock at an assumed public offering price of
$22.80 per share, after deducting the estimated underwriting discounts,
commissions and estimated offering expenses, our as adjusted net tangible book
value as of March 31, 2002, would have been $193,960,000, or $4.49 per share.
This represents an immediate increase in net tangible book value of $1.03 per
share to existing shareholders and an immediate dilution of $18.31 per share to
you, as illustrated in the following table:



<Table>

Net tangible book value per share after this offering.......            4.49
                                                                      ------

</Table>


     You will experience additional dilution upon the exercise of outstanding
options, and to the extent that we issue new options or issue additional shares
of capital stock in the future, you may experience further dilution.

     The number of shares of common stock outstanding used for existing
shareholders in the table above is based on shares outstanding as of March 31,
2002, and excludes:

     - 4,365,061 shares of common stock issuable upon exercise of options
       outstanding at a weighted average exercise price of $7.66 per share, of
       which options to purchase 2,356,671 shares at a weighted average exercise
       price of $8.26 were exercisable; and

     - 87,989 shares available for future grant under our equity incentive plans
       as of March 31, 2002 and an additional 4,200,000 shares available for
       future grant under our equity incentive plans approved by our
       shareholders on May 29, 2002.

                           BACKGROUND OF THE COMPANY

     Cobalt Corporation was formed in March 2001 and is the successor to
substantially all of the operations of (i) Blue Cross & Blue Shield United of
Wisconsin, which we refer to as "BCBSUW," and (ii) United Wisconsin Services,
Inc., which was a publicly traded subsidiary of BCBSUW listed on the New York
Stock Exchange under the symbol "UWZ" and which we refer to as "UWS."

     BCBSUW was formed in 1939 as a non-stock, not-for-profit service insurance
corporation, and since that time has operated as a health insurer licensed by
the Association to make exclusive use of the Association's trademarks in
Wisconsin. In 1991, in order to gain increased access to capital markets, BCBSUW
contributed certain of its managed health care operations (including its HMO
operations) to UWS, its wholly-owned for-profit subsidiary. Through public stock
offerings completed in 1991, 1994 and 1995, BCBSUW reduced its ownership of UWS
stock to approximately 49% by February 1995.

     In March 2001, the operations of BCBSUW and UWS were combined in a series
of transactions that we refer to as the "Combination." In these transactions,
BCBSUW converted from a non-profit to a shareholder-owned business,
contemporaneous with an exchange agreement approved by the Association and the
OCI. Under the exchange agreement:

     - BCBSUW converted its form from a non-stock service insurance corporation
       to a stock insurance corporation;

     - BCBSUW issued all of its outstanding stock to the Foundation, a
       charitable organization formed for the purpose of receiving the stock of
       BCBSUW;

     - the Foundation transferred all of the stock of BCBSUW to UWS (making
       BCBSUW a wholly-owned subsidiary of UWS), in exchange for 31,313,390
       shares of our newly issued common stock; and

     - the combined entity changed its name to "Cobalt Corporation."

     As a result of the Combination, BCBSUW is now one of our wholly-owned
subsidiaries, and the Foundation now owns approximately 77% of our outstanding
common stock.

     As required under accounting principles generally accepted in the United
States, we accounted for the Combination as a purchase by BCBSUW of the shares
of UWS common stock which it did not own before the Combination. As a result,
the financial statements and related information contained in this prospectus
reflect the business and assets of BCBSUW (rather than UWS) before March 31,
2001, and the combined businesses of BCBSUW and UWS after that date. See
"Selected Consolidated Financial and Operating Data."


     In connection with the Combination, the Association rules required the
Foundation to deposit all of its shares of our common stock into a voting trust
and to sell its shares within prescribed time periods. Accordingly, we, the
Foundation and Marshall & Ilsley Trust Company, as trustee, have entered into a
Voting Trust and Divestiture Agreement, which is summarized under "Agreements
With Foundation -- Certain Agreements Executed in Connection with the
Combination -- Voting Trust and Divestiture Agreement."



     We also entered into a Registration Rights Agreement with the Foundation in
connection with the Combination. Under the Registration Rights Agreement, we
agreed, subject to various terms and conditions, to register with the Securities
and Exchange Commission the Foundation's shares of our common stock for sale to
the public over a period of time, and the Foundation has granted us the right to
buy shares of our common stock from the Foundation in some cases. The
Registration Rights Agreement is summarized in more detail under "Agreements
With Foundation -- Certain Agreements Executed in Connection with the
Combination -- Registration Rights Agreement."


                                        22


               SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA

     We derived the following selected consolidated financial and operating data
from our consolidated financial statements. You should read these data in
conjunction with our consolidated financial statements, the related notes
thereto, "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and other financial information included and incorporated
by reference in this prospectus.

     The following selected consolidated financial balance sheet data as of
December 31, 2000 and 2001 and selected consolidated financial statement of
operations data for the three years ended December 31, 2001 are derived from our
consolidated financial statements, which are included and incorporated by
reference in this prospectus and have been audited by Ernst & Young LLP, our
independent auditors. The selected consolidated financial balance sheet data as
of December 31, 1999 and 1998 and selected consolidated financial statement of
operations data for the two years ended December 31, 1998 are derived from
audited consolidated financial statements not included in this prospectus. The
selected consolidated financial balance sheet data as of December 31, 1997 are
derived from unaudited financial statements.

     The financial data as of March 31, 2002 and for the three-month periods
ended March 31, 2002 and 2001 are derived from unaudited consolidated financial
statements. The unaudited consolidated financial statements include all
adjustments, consisting of normal recurring accruals, which we consider
necessary for a fair presentation of the financial position and the results of
operations for these periods. Operating results for the three-month periods
ended March 31, 2002 and 2001 are not necessarily indicative of the results that
may be expected for the entire years ending December 31, 2002 and 2001.


     For financial reporting purposes, the Combination is treated as a reverse
purchase transaction, whereby BCBSUW becomes the acquirer and reporting entity.
Therefore, the accompanying selected consolidated financial data present the
combined balance sheet data of both BCBSUW and UWS as of December 31, 2001 and
March 31, 2002, including purchase accounting adjustments for the Combination.
The selected consolidated balance sheet data presented prior to March 31, 2001
represents only the accounts of BCBSUW, accounting for BCBSUW's investment in
UWS and AMSG as investments in affiliates. The selected consolidated statement
of operations data for the year ended December 31, 2001, report the operations
of BCBSUW and post-combination UWS, with BCBSUW's investment in AMSG continuing
to be accounted for as an investment in affiliate. For the three-month period
ended March 31, 2001 and each of the four years ended December 31, 2000, the
selected consolidated statement of operations data represent only the operating
results of BCBSUW, accounting for BCBSUW's investment in UWS and AMSG as
investments in affiliates.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following presents our management's discussion and analysis of our
financial condition and results of operations as of the dates and for the
periods indicated. You should read this discussion in conjunction with our
consolidated financial statements and notes thereto which begin on page F-1 and
the information set forth under the caption "Risk Factors." This discussion
contains forward-looking statements that involve risks and uncertainties. Actual
results could differ significantly from those anticipated in these
forward-looking statements. See "Forward-Looking Statements."

OVERVIEW

     We are the leading managed care company in Wisconsin, offering a portfolio
of managed care and insurance products to employers, individuals and government
entities. We have an exclusive license to utilize the Blue Cross and Blue Shield
service marks in the State of Wisconsin, giving us a unique position in that
geographic market. As of March 31, 2002, we serviced approximately 605,000 lives
in our health insurance operations and approximately 343,000 lives in our dental
program.


     During 1999 and 2000, we experienced large operating losses. These losses
were due primarily to our Medicare+Choice line of business and the self-funded
business. Additionally, UWS reported losses arising from its federal employee
contracts and a conversion of certain of its provider arrangements from
capitation to a fee for service model. In addition, during this period we
experienced difficulties in implementing new information systems, which impaired
our ability to identify trends indicating increasing medical costs, leading to
writing unprofitable contracts. These factors led to increased medical loss
ratios and resulting losses. In addition, the resulting adverse effect on our
capital position led to discussions with the OCI and the Association regarding
our plans for capital improvement.


     To address these issues, we developed a plan to improve our core business
while divesting non-core businesses and assets. In our core business, we focused
on:

     - discontinuing unprofitable business lines;

     - repricing or terminating unprofitable customer contracts;

     - improving underwriting techniques and pricing products appropriately to
       reflect underlying cost trends;

     - negotiating improved terms in our provider contracts; and

     - bolstering management in key areas, including the Milwaukee market.

     In implementing this plan, we exited the Medicare+Choice line of business
as of January 1, 2002 and elected to not renew certain unprofitable customer
contracts. We have also strengthened our senior actuarial and underwriting
staff, adopted more stringent underwriting standards and applied these standards
to achieve better pricing for new contracts, as well as those contracts up for
renewal. In addition, we have negotiated more favorable provider contracts and
have improved our product mix by increasing enrollment in our Medicare
supplement business and reducing self-funded membership.


     We have divested certain non-core assets. We sold our behavioral health and
medical management subsidiary, Innovative Resource Group, for $27 million,
resulting in a pre-tax gain of approximately $11 million. Additionally, during
2002 we reduced our investment in AMSG common stock from 45% of the shares
outstanding to 15%, raising net proceeds of approximately $69 million and
resulting in a pre-tax gain of approximately $10 million, while relieving us of
a significant portion of our statutory capital requirement relating to AMSG.


     Through this strategy, we have improved our core operations. Although
resulting in decreased membership and premium revenue for BCBSUW and our HMOs,
our strategy has substantially improved loss ratios and overall profitability.
Our net income from continuing operations improved to $13.2 million in the first
quarter of 2002 from net losses of $42.7 million in 1999, $40.0 million in 2000
and
                                        26


$23.3 million in 2001. By 2001, we were experiencing significant improvement in
our core operations, although we nonetheless recorded a substantial net loss,
principally due to a $25.2 million writedown of our minority investment in AMSG.
We intend to continue our strategy of focusing on our core business and seeking
ways to divest additional non-core assets and unprofitable business.


     For financial reporting purposes, we have been able to reduce income tax
expense through utilization of net operating loss carryforwards. As a result of
our recent profitability, including gains on the sale of Innovative Resource
Group and common stock of AMSG, we anticipate that we will exhaust, sometime
between December 31, 2002 and March 31, 2003, those of our net operating loss
carryforwards that may, under applicable accounting guidelines, be used to
benefit our operating results. At such time, we will begin accruing income tax
expense at the statutory rate of 40%. See Note 12 of Notes to Consolidated
Financial Statements.



OUTLOOK



     As a result of favorable developments in our operations described elsewhere
in this prospectus and increasing visibility for our prospects in 2003, we are
updating our earnings guidance for 2002 and issuing earnings guidance for 2003.
Based on currently available information, for 2002 we anticipate pre-tax income
from continuing operations of approximately $49 million to $51 million, net
income from continuing operations of approximately $44 million to $46 million
and earnings per share from continuing operations of approximately $1.05 to
$1.10. These estimates assume an effective tax rate of 10% and completion of
this offering in July 2002. Based on currently available information, for 2003
we anticipate pre-tax income from continuing operations of approximately $62
million to $66 million, net income from continuing operations of approximately
$37 million to $39 million and earnings per share from continuing operations of
approximately $0.85 to $0.90. These estimates assume an effective tax rate of
40%. The increase in the tax rate for 2003 compared to 2002 reflects the
anticipated exhaustion of net operating loss carryforwards available to benefit
our operating results. See "-- Overview."



     In calculating these estimates, we exclude the results of operations of
Innovative Resource Group, which we sold in March 2002, our equity in the
operations of AMSG and gains from the sale of Innovative Resource Group and
shares of common stock of AMSG, although we include investment income from the
cash proceeds from these transactions as well as from the sale of stock in this
offering. We also assume the issuance of 2,500,000 primary shares of common
stock in this offering in July 2002.



     The foregoing estimates are forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. These estimates are not
guarantees of future performance, and we caution investors that they involve
risks and uncertainties. In making these estimates, we have assumed, among other
things, that we will continue to implement successfully our strategy of
improving our core operations, particularly by reducing loss and expense ratios.
If this or any of our other assumptions is incorrect, we may not attain our
earnings estimates. Other risks that could prevent us from attaining these
estimates are described under "Risk Factors," and we urge investors to consider
those risks carefully. We undertake no obligation to update these estimates for
any reason after the date of this prospectus.

RESULTS OF OPERATIONS

     All financial data in the Results of Operations section are gross numbers
and, therefore, are not net of intracompany eliminations.

 COMPARISON OF RESULTS OF FIRST QUARTER 2002 WITH FIRST QUARTER 2001

     The results for the first quarter of 2002 include the operations of the
combined UWS and BCBSUW entities, with AMSG accounted for using the equity
method. The results for the first quarter of 2001 include the operations of
BCBSUW and its investment in UWS and AMSG accounted for using the equity method.
Hence, these two periods are not comparable, and the comparison between the
first quarter of 2002 and the first quarter of 2001 is largely explained by the
addition of UWS results in 2002.

                                        28


     TOTAL REVENUES


     Total revenues for the three months ended March 31, 2002 increased 104.1%
to $381.0 million from $186.7 million for the three months ended March 31, 2001.
This increase was due primarily to the Combination and the resultant addition of
the UWS business. Another factor contributing to the increase was premium rate
increases on insured medical product business.


    Insured Medical Products

     Insured medical products revenue for the three months ended March 31, 2002
increased 112.9% to $305.1 million from $143.3 million for the three months
ended March 31, 2001. The number of insured medical members as of March 31, 2002
increased 90.4% to 469,784 from 246,675 as of March 31, 2001. The increase in
both premium revenues and membership is primarily due to the Combination and the
resultant addition of the UWS business, which contributed 233,634 members,
offset by a slight decrease due largely to BCBSUW's exit from the
Medicare+Choice program. Also contributing to the increase is an overall
increase in premium per member per month for BCBSUW of approximately 12%.

    Self-Funded Products

     Self-funded administrative fees for the three months ended March 31, 2002
decreased 6.5% to $7.2 million from $7.7 million for the three months ended
March 31, 2001. The decrease is primarily attributable to a reduction in the
number of dental self-funded members to 35,648 as of March 31, 2002 from 39,019
as of March 31, 2001. The reduction in membership is the effect of our repricing
the self-funded business in order to eliminate unprofitable business.

    Specialty Managed Care Products and Services


     Specialty managed care products and services revenue for the three months
ended March 31, 2002 increased 504.0% to $45.3 million from $7.5 million for the
three months ended March 31, 2001. This increase is due primarily to the
addition of the UWS business as a result of the Combination. Total revenue of
$7.5 million for the three months ended March 31, 2001 includes only premium
revenue from the BCBSUW insured dental business. In comparison, total revenue of
$45.3 million for the three months ended March 31, 2002 includes combined
premium revenue of $6.5 million for the BCBSUW insured dental business and $29.8
million of the UWS dental, disability, life and accidental death and
dismemberment business, and other revenues of $9.0 million related to the UWS
workers' compensation business, receivables management, cost containment
services and electronic claims services. The number of specialty managed care
products and services members, which relate to the dental, disability, life and
accidental death and dismemberment insurance business, increased 304.0% to
575,892 as of March 31, 2002 from 142,531 as of March 31, 2001, also due
primarily to the Combination.


    Government Intermediary Services

     Government intermediary services revenue for the three months ended March
31, 2002 increased 7.1% to $28.8 million from $26.9 million for the three months
ended March 31, 2001. The increase in revenues from 2001 to 2002 is primarily
attributable to an increase in administrative fees charged to Medicare and other
government programs. The amount of these fees is determined, in part, based on
allowable expenses incurred by our United Government Services subsidiary in
administering these programs. The increase in 2002 revenues is, therefore, the
result of increases in these allowable expenses, primarily related to annual
increases in salaries and other compensation expenses, which are charged back to
these programs.

     INVESTMENT RESULTS

     Net investment results include investment income and realized gains
(losses) on the sale of investments, which include cash equivalents, bonds,
stocks and other invested assets. Net investment results for the three months
ended March 31, 2002 increased 38.1% to $2.9 million from $2.1 million for the
three months ended March 31, 2001. As a result of the Combination and the
resultant addition of
                                        29



UWS, net investment income from invested assets increased $2.2 million, from
$0.6 million for the three months ended March 31, 2001 to $2.8 million for the
three months ended March 31, 2002. In addition, realized gains increased to $0.1
million for the three months ended March 31, 2002 compared with an insignificant
realized loss for the three months ended March 31, 2001. However, offsetting
this increase was the elimination of BCBSUW investment income related to
intracompany financing arrangements with UWS, subsequent to March 31, 2001, due
to the Combination. This intracompany investment income amounted to $1.3 million
for the three months ended March 31, 2001. Average annual investment yields,
excluding net realized gains, investment income from affiliates and other
interest income were 4.8% for the three months ended March 31, 2002 and 6.4% for
the three months ended March 31, 2001.



     Average invested assets for the three months ended March 31, 2002 increased
to $231.6 million, compared to $37.2 million for the three months ended March
31, 2001. The increase in 2002 is due in large part to the Combination, which
increased invested assets by $135.9 million as of March 31, 2001. In addition,
in March 2002, we received cash proceeds of $17.0 million from the sale of
Innovative Resource Group, LLC and $18.2 million from the sale of 1.4 million
shares of the common stock of AMSG.


     EXPENSE RATIOS

     Loss Ratio

     The insured medical products loss ratio for the three months ended March
31, 2002 (including both the BCBSUW insured medical business and the HMO
operations provided through the addition of UWS) was 87.9% compared with 86.0%
for the three months ended March 31, 2001 (which includes only the BCBSUW
business). The increase in the medical loss ratio for the first quarter of 2002
is primarily the result of the Combination and the resultant addition of the UWS
business, which has run at a higher loss ratio than the BCBSUW insured medical
business.

     The BCBSUW insured medical products loss ratio (excluding HMO business) for
the three months ended March 31, 2002 improved to 84.8% from 86.0% for the three
months ended March 31, 2001. This improvement is a result of premium rate
increases and the impact of the exit from the Medicare+Choice program. This
compares to the HMO loss ratio of 90.5% for the three months ended March 31,
2002, which was approximately the same as the ratio of 90.7% for the three
months ended March 31, 2001. After March 31, 2001, the HMOs experienced
significantly higher than anticipated claim costs on a large block of enrollment
which transitioned from capitated to fee-for-service provider arrangements
effective January 1, 2001. As a result, the HMO loss ratio increased to 94.4%
for the twelve months ended December 31, 2001. Thus, the comparison of the HMO
loss ratio for the first quarter of 2002 and 2001 does not demonstrate the
significant improvement in the loss ratio for the first quarter of 2002 compared
to the last nine months of 2001, which resulted from premium rate increases and
the reduction of unprofitable business.

     Selling, General, Administrative and Other Expense Ratio

     For our insurance subsidiaries, the selling, general, administrative and
other ("SGA") expense ratio includes commissions, administrative expenses,
premium taxes and other assessments and claim interest expense. For
non-insurance subsidiaries, SGA includes operating expenses only.

     The insured medical products SGA expense ratio for the three months ended
March 31, 2002 was 10.8% compared with 10.3% for the three months ended March
31, 2001. The slight increase in the SGA expense ratio for the three months
ended March 31, 2002 is primarily due to changes in the mix of business due to
the addition of the UWS insured medical business and the reduction in HMO
membership due to the exit of unprofitable business in December 2001 and January
2002.

     The combined loss and expense ratio for specialty managed care products and
services for the three months ended March 31, 2002 improved to 96.7% from 100.0%
for the three months ended March 31, 2001. The improvement in 2002 is due to the
addition of the UWS specialty managed care products and services, particularly
the service related products such as subrogation, hospital bill audit and
electronic

                                        30


claims services, which have run at a lower overall operating expense ratio than
the combined loss and expense ratio for the specialty insurance lines. The ratio
for the three months ended March 31, 2001 is comprised entirely of the loss and
expense ratio for the BCBSUW insured dental business.

     The expense ratio for government intermediary services for the three months
ended March 31, 2002 improved to 98.2% from 99.3% for the three months ended
March 31, 2001, due to the effect of higher chargeable expenses in 2001 related
to the implementation of new Medicare government contracts awarded and the
renewal of existing Medicaid contracts with increased funding. Also, United
Government Services incurred additional operating expenses in 2001 related to
the consolidation of claim processing systems in order to gain greater
operational efficiencies. These initiatives are substantially complete as of
March 31, 2002.

     The SGA expenses for the three months ended March 31, 2002 were reduced by
net $2.4 million for certain nonrecurring items, including a favorable vendor
settlement.

     OTHER EXPENSES

     We have a bank line of credit, in which certain subsidiaries, excluding the
corporate holding company, can participate. The line of credit permits aggregate
borrowings up to $20.0 million, with company specific maximums for the
participating companies. In addition, we have a term business note for the
corporate holding company with a commercial bank for $7.5 million originated on
December 31, 2001. Interest expense on the credit arrangements discussed above
totaled $0.2 million for the three months ended March 31, 2002. There was no
interest expense on debt for the three months ended March 31, 2001.

     As a result of the adoption of Statement of Financial Accounting Standards
Board No. 142 on January 1, 2002, there was no goodwill amortization recorded
for the three months ended March 31, 2002, compared with goodwill amortization
of $0.2 million recorded for the three months ended March 31, 2001. Goodwill
amortization recorded for the three months ended March 31, 2001 primarily
represents amortization related to the 1999 purchase by BCBSUW of 1.4 million
additional shares of UWS stock, which was amortized on a straight-line basis
over a period of 15 years. The reduction in goodwill between March 31, 2002 and
December 31, 2001 reflects adjustments to the tax related portion of goodwill
recorded from the Combination. These adjustments relate to the recognition of a
valuation allowance on the net deferred income tax asset that was previously
recorded by UWS. The goodwill was adjusted downward during the first quarter of
2002 by $3.0 million due to the utilization of the related UWS net operating
losses to offset pre-tax earnings.

     INCOME (LOSS) FROM INVESTMENT IN AFFILIATES

     Income (loss) from investment in affiliates improved to a gain of $2.8
million for the three months ended March 31, 2002 compared to a loss of $1.9
million for the three months ended March 31, 2001. The results for the three
months ended March 31, 2002 are primarily comprised of our equity in AMSG net
income of $2.4 million combined with a gain of $0.4 million on the sale of 1.4
million shares of AMSG stock during the quarter. The results for the three
months ended March 31, 2001 include equity in the AMSG net loss for the quarter
of $2.3 million, offset by BCBSUW's equity in UWS income of $0.4 million.

     INCOME FROM DISCONTINUED OPERATIONS


     Income from discontinued operations of $9.4 million relates to the sale of
Innovative Resource Group to APS Healthcare Bethesda, Inc. on March 29, 2002.
Income from discontinued operations includes the first quarter net loss of IRG
of $0.5 million, offset by an after tax realized gain on the sale of $9.9
million. There were no operations to report for discontinued operations for the
first quarter of 2001, since Innovative Resource Group was not considered part
of our organization for financial reporting purposes until the second quarter of
2001.


                                        31


     NET INCOME

     Consolidated net income improved for the three months ended March 31, 2002
to a net gain of $22.6 million compared to $1.3 million for the three months
ended March 31, 2001. The $22.6 million of income for the three months ended
March 31, 2002 was the combination of $11.6 million in operating income from
continuing operations, combined with $2.8 million of income from investment in
affiliates and $9.4 million of income from discontinued operations, net of tax,
offset by income tax expense on continuing operations of $1.2 million. The
improved operating results primarily reflect the improved profitability of the
self-funded business and a net favorable settlement recorded as a reduction of
SGA expenses.

     The improvement in profitability on the self-funded business is largely
attributable to an increase in revenues from participation in the BlueCard PPO
program. The growth in BlueCard revenues is due to an increase in processing
volumes in 2002, due to growth in the program. Administrative fee revenues
related to the BlueCard program amounted to $3.5 million for the three months
ended March 31, 2002, compared to $1.6 million for the three months ended March
31, 2001. Operating income related to the BlueCard program was $1.3 million for
the three months ended March 31, 2002, compared to $0.4 million for the three
months ended March 31, 2001.

     As of March 31, 2002, we had federal net operating loss carry-forwards of
$114.9 million available to offset future taxable income. A full valuation
allowance has been established against net deferred tax assets. We had a current
tax expense of $0.2 million and a deferred tax expense of $1.0 million for the
three months ended March 31, 2002 on continuing operations. We did not have any
income tax expense for the three months ended March 31, 2001.

  COMPARISON OF RESULTS OF FISCAL YEAR 2001 WITH FISCAL YEAR 2000

     The results for 2001 include the operations of the combined UWS and BCBSUW
entities effective March 31, 2001 with AMSG continuing to be accounted for using
the equity method. Prior to March 31, 2001, the results include the operations
of BCBSUW and its investment in UWS and AMSG accounted for using the equity
method. The comparison between 2001 and 2000 is largely explained by the
addition of UWS results for the last three quarters of 2001 following the
Combination.

     TOTAL REVENUES

     Total revenues in 2001 increased 121.8% to $1,425.7 million from $642.7
million in 2000. The increase in 2001 is due primarily to the Combination and
the resultant addition of the UWS business. UWS contributed $686.8 million in
revenue in 2001 or 106.9% of the total 121.8% increase for the year. Other
factors contributing toward the increase in 2001 include premium rate increases
on the insured medical product business, the re-pricing of self-funded products
and new government fee based contracts.

     Insured Medical Products

     Insured medical revenue in 2001 increased 125.3% to $1,150.4 million from
$510.6 million in 2000. The increase in 2001 is primarily due to the Combination
and the resultant addition of UWS business. The addition of UWS premiums
resulted in an increase to premium revenue for 2001 of $574.4 million or 112.5%
of the total 125.3% increase. The number of insured medical members in 2001
increased 107.8% to 530,480 from 255,289 in 2000. The total membership increase
of 275,191 reflects a decrease of 18,474 members in BCBSUW insured medical
membership, offset by the addition of 293,665 members from the UWS insured
medical business.

     Self-Funded Products

     Self-funded administrative fees in 2001 increased 13.8% to $28.1 million
from $24.7 million in 2000. The increase in 2001 results from an increase of
approximately 60% in the administrative fee per member per month due to the
targeted re-pricing of self-funded business in order to eliminate unprofitable
business.

                                        32


The pricing increases were offset by a reduction of 30.2% in non-HMO self-funded
membership to 164,415 as of 2001 from 235,604 as of 2000.

     Specialty Managed Care Products and Services


     Specialty managed care products and services revenue in 2001 increased
374.9% to $142.0 million from $29.9 million in 2000. The increase in 2001
primarily resulted from the addition of $113.4 million in revenues from the UWS
specialty business, which includes life, accidental death and dismemberment,
dental, disability, workers' compensation products, along with electronic claim
submission, cost containment and receivables management services. The number of
specialty managed care members in 2001 increased to 592,566 from 145,955 in
2000. The total increase in membership of 446,611 reflects a decrease of 13,981
members in BCBSUW insured dental membership, offset by the addition of 460,592
members from the UWS specialty risk business.


     Government Intermediary Services

     Government intermediary services revenue in 2001 increased 66.7% to $117.2
million from $70.3 million in 2000. The increase from 2000 to 2001 is
attributable to significant growth in the volume of Medicare claims processed,
due to being awarded additional government contracts. Effective December 1,
2000, United Government Services became the Medicare Part A Intermediary for
certain additional states and U.S. territories. In addition, also effective
December 1, 2000, United Government Services became the Regional Home Health
Intermediary for certain additional states and U.S. territories.

     INVESTMENT RESULTS

     Net investment results in 2001 increased 30.2% to $12.5 million from $9.6
million in 2000. The addition of UWS increased 2001 investment results by $8.0
million. However, offsetting this increase was the elimination of BCBSUW
investment income related to intra-company financing arrangements with UWS,
subsequent to March 31, 2001, due to the Combination. This intra-company
investment income amounted to $5.5 million in 2000, as compared to $1.3 million
in 2001, based on the amount recorded through March 31, 2001. Average annual
investment yields, excluding net realized gains, intra-company investment income
and other interest income were 5.8% and 7.0% for 2001 and 2000, respectively.


     Average invested assets in 2001 increased 255.1% to $166.9 million from
$47.0 million in 2000. The improvement in 2001 is primarily the result of the
acquisition of UWS at the end of the first quarter of 2001, which increased our
invested assets by $200.9 million as of December 31, 2001.


     Net investment gains (losses) are realized in the normal investment process
in response to market opportunities. Realized gains were $0.8 million in 2001
compared to realized losses of $0.5 million in 2000.

     EXPENSE RATIOS

     Loss Ratio

     The insured medical products loss ratio for 2001 (which consists of the
BCBSUW insured medical business for the full twelve months, and the HMO business
after March 31, 2001) was 90.7%, compared with 93.5% for 2000 (which includes
only the BCBSUW business). The decrease in the medical loss ratio in 2001 is
primarily the result of pricing increases and other cost control measures
instituted in response to higher than anticipated medical utilization and cost
trends. In addition, the higher loss ratio for 2000 also reflects the effect of
a premium deficiency reserve of $3.6 million recorded during the second half of
2000 on the Medicare+Choice business. The premium deficiency reserve amount
recorded as of December 31, 2000 represented estimated losses throughout 2001.
The remainder of the premium deficiency reserve was reversed in 2001, as a
result of our exiting the business effective January 1, 2002.

     The BCBSUW medical loss ratio for 2001 (excluding HMO business) was 85.7%,
compared with 93.5% for 2000. This improvement is partially attributable to a
reduction in the medical loss ratio in the Medicare+Choice business from 127.3%
in 2000 to 94.8% in 2001, on comparable revenues. The loss ratio
                                        33


for 2001 for the HMO business was 94.4%, compared with 95.2% in 2000. The slight
improvement is the result of our re-pricing efforts and reduction of
unprofitable business.

    Selling, General, Administrative and Other Expense Ratio

     The insured medical products SGA expense ratio for 2001 was 9.6%, compared
with 12.0% for 2000. The improved SGA expense ratio in 2001 is the result of
additional expense control measures instituted, combined with a higher premium
base in 2001 due to pricing increases. In addition, the insured medical products
SGA ratio in 2000 includes the effect of a $2.4 million write-off of deferred
acquisition costs related to the Medicare Risk business.

     The self-funded products expense ratio for 2001 improved to 113.9% from
144.7% in 2000. This improvement is due to continued efforts to eliminate
unprofitable business through price increases.

     The specialty managed care products and services combined loss and expense
ratio in 2001 improved to 98.0% compared with 100.0% for 2000. The 2000 ratio
includes only the BCBSUW dental business, whereas the 2001 ratio includes both
BCBSUW dental and the UWS specialty managed care products and services business.
The UWS specialty business includes cost containment services and electronic
claims services, which typically run at a lower overall operating expense ratio,
thus improving the combined ratio.


     The expense ratio for government intermediary services in 2001 and 2000
remained constant at 99.3%.


     OTHER EXPENSES

     Interest expense related to the bank line of credit in 2001 and 2000 was
$0.6 million and $0.3 million, respectively.


     Goodwill amortization totaling $5.1 million and $0.6 million was recorded
for 2001 and 2000, respectively. Of the total $5.1 million of goodwill
amortization recorded for 2001, $3.3 million relates to $68.6 million of
goodwill recorded in 2001 for the Combination as a result of purchase
accounting, which until the effective date of Financial Accounting Standards
Board No. 142 was being amortized on a straight-line basis over a period of 15
years. In addition, the 2001 amortization expense includes amortization related
to the 1999 purchase by BCBSUW of 1.4 million additional shares of UWS stock,
which has been amortized on a straight-line basis over a period of 15 years.
Amortization expense for 2000 included amortization related to the purchase by
BCBSUW of the 1.4 million additional shares of UWS stock discussed above. In
addition, goodwill amortization has been recorded for various past acquisitions
of subsidiaries and additional insurance business.


     LOSS FROM INVESTMENT IN AFFILIATES

     The loss from investment in affiliates increased to $22.7 million in 2001
from $6.5 million in 2000. The $22.7 million loss in 2001 is comprised of our
pro rata share of AMSG's net income of $2.0 million for 2001, BCBSUW's share of
UWS income of $0.4 million for the first quarter of 2001, and other affiliate
net income of $0.1 million, offset by a $25.2 million writedown of the
investment in AMSG to the fair value of AMSG's common stock quoted on the New
York Stock Exchange as of December 31, 2001. This writedown was deemed
appropriate based on management's decision to no longer classify the investment
in AMSG as a strategic long-term asset. The 2000 loss from investment in
affiliates of $6.5 million is comprised of a $7.6 million loss related to UWS,
offset by a $1.1 million equity share in the net income of AMSG.

     INCOME FROM DISCONTINUED OPERATIONS

     Income from discontinued operations for 2001 of $1.0 million includes
Innovative Resource Group's net operating results for the nine months ended
December 31, 2001.

                                        34


     NET LOSS

     Consolidated net results improved in 2001 to a loss of $22.3 million
compared to a loss of $40.0 million in 2000. The $22.3 million net loss in 2001
was the combination of an operating loss of $2.4 million and a loss from
investment in affiliates of $22.7 million as discussed above, offset by an
income tax benefit of $2.0 million and an after-tax gain on discontinued
operations of $1.0 million. The improved 2001 operating results reflect
improvement in the insured loss and SGA ratios, increases in administrative fees
on the self-funded business and continued growth in government contract business
over the prior year.

     As of December 31, 2001, we had federal net operating loss carry-forwards
of approximately $141.0 million available to offset future taxable income. A
full valuation allowance has been established against net deferred tax assets.
We had a current income tax benefit of $2.2 million in 2001 in conjunction with
the formation of Cobalt compared to no current income tax expense or benefit in
2000. We recorded an immaterial deferred tax benefit in 2001 and a deferred tax
expense of $0.5 million in 2000, which related to a valuation allowance from a
prior period.

 COMPARISON OF RESULTS OF FISCAL YEAR 2000 WITH FISCAL YEAR 1999

     Results for 2000 and 1999 include the operations of BCBSUW and its
investment in UWS and AMSG accounted for using the equity method.

     TOTAL REVENUES

     Total revenues in 2000 increased 24.6% to $642.7 million from $515.7
million in 1999. The increase in 2000 resulted primarily from increased
membership and premium rate increases on the medical insurance business and new
government contracts.

     Insured Medical Products

     Insured medical revenue in 2000 increased 30.1% to $510.6 million from
$392.6 million in 1999. The increased premium is due to the number of insured
medical members in 2000 increasing 15.4% to 255,289 from 221,266 in 1999,
combined with increases in per member per month premium due to premium rate
increases.

     Self-Funded Products

     Self-funded administrative fees in 2000 decreased 5.0% to $24.7 million
from $26.0 million in 1999. The decrease in self-funded administrative fees in
2000 primarily resulted from a 21.1% decrease in self-funded membership from
298,799 in 1999 to 235,604 in 2000. The decrease in membership was offset by an
increase of 20.7% in the average self-funded administrative fee per member per
month. The decrease in revenue and membership is due to aggressive pricing on
targeted group contracts and subsequent loss of unprofitable business.

     Specialty Managed Care Products and Services

     Specialty managed care products and services revenue in 2000 increased 7.6%
to $29.9 million from $27.8 million in 1999. The number of specialty managed
care members in 2000 decreased 3.6% to 145,955 from 151,471 in 1999. The slight
decrease in membership was offset by premium rate increases, resulting in an
overall increase in revenues.

     Government Intermediary Services

     Government intermediary services revenue in 2000 increased 34.4% to $70.3
million from $52.3 million in 1999. The increase from 1999 to 2000 is largely
attributed to becoming the Medicare Part A Intermediary for the states of
Virginia and West Virginia as of September 1, 1999.

                                        35


     INVESTMENT RESULTS

     Net investment results in 2000 decreased 48.1% to $9.6 million from $18.5
million in 1999, primarily due to a decrease in average invested assets, as
discussed below. Average annual investment yields, excluding net realized gains,
intra-company investment income and other interest income were 7.0% and 6.1% for
2000 and 1999, respectively.

     Average invested assets in 2000 decreased 37.9% to $47.0 million from $75.7
million in 1999. The decrease in average invested assets during 2000 is a result
of cash requirements necessary to fund operating losses.

     Net investment gains (losses) are realized in the normal investment process
in response to market opportunities. Realized losses were $0.5 million in 2000
compared to realized gains of $8.0 million in 1999. BCBSUW received interest
income of $5.5 million and $4.8 million in 2000 and 1999, respectively, on a
$70.0 million note from UWS.

     EXPENSE RATIOS

     Loss Ratio

     The insured medical products loss ratio for 2000 was 93.5% compared with
90.5% for 1999. The increase in the medical loss ratio in 2000 is primarily the
result of greater than anticipated medical utilization and cost trends. The loss
ratio on the Medicare+Choice business deteriorated to 127.3% in 2000 from 116.5%
in 1999, on revenues of $66.8 million and $21.1 million, respectively.

     Selling, General, Administrative and Other Expense Ratio


     The insured medical products SGA expense ratio for 2000 improved to 12.0%
compared with 14.3% for 1999. The improvement in 2000 reflects the effect of
expense controls instituted, combined with a higher premium base due to
membership and premium rate increases, offset in part by a $2.4 million
write-off of deferred acquisition costs related to the Medicare+Choice business.


     The self-funded products expense ratio for 2000 improved to 144.7% from
166.9% in 1999. This improvement is due to price increases on targeted group
contracts, which resulted in the loss of unprofitable business.

     The specialty managed care products and services combined loss and expense
ratio in 2000 improved to 100.0% from 108.3% in 1999. The expense ratio for
government intermediary services in 2000 was 99.3% compared to 98.4% in 1999,
which reflects a change in the overall average government reimbursement level
due to changes in the mix of business related to additional government business
acquired in 2000.

     OTHER EXPENSES

     Interest expense related to the bank line of credit in 2000 and 1999 was
$0.3 million and $0.6 million, respectively.

     In 1999, BCBSUW purchased 1.4 million additional shares of UWS stock. The
excess of cost over the fair value of net assets acquired has been recorded as
goodwill and was amortized on a straight-line basis over a period of 15 years.
Amortization expense was $0.6 million and $0.2 million for 2000 and 1999,
respectively.

     LOSS FROM INVESTMENT IN AFFILIATES

     The loss from investment in affiliates decreased to $6.5 million in 2000
from $22.7 million in 1999. The loss in 2000 is comprised of a loss of $7.6
million from UWS, offset by a gain of $1.1 million from AMSG. For 1999, the
affiliate results recorded by us include losses of $12.7 million from UWS and
$10.0 million from AMSG.

                                        36


     NET LOSS

     Consolidated net results improved in 2000 to a loss of $40.0 million
compared to a loss of $42.7 million in 1999. The poor results in 2000 resulted
primarily from the combination of a $32.9 million operating loss and a $6.5
million loss from investment in affiliates, net of tax. The $32.9 million
operating loss is due to a $20.6 million loss before income taxes on insured
business, which experienced greater than anticipated medical utilization and
cost trends, combined with a $10.7 million loss before income taxes on
self-funded business. In addition, the 2000 results include the effect of $3.3
million in transaction expenses in preparation for the Combination. Partially
offsetting these losses was $1.2 million in income before income taxes on
government contracts. The 1999 loss was also attributable to greater than
anticipated utilization on the insured business and losses on the self-funded
business.

     Because of operating losses, BCBSUW did not have current income tax expense
or benefit in 2000 or 1999. BCBSUW had deferred tax expense of $0.5 million in
2000, which relates to a valuation allowance from a prior period. There was no
deferred tax benefit in 1999.

LIQUIDITY AND CAPITAL RESOURCES

     Our sources of cash flow consist primarily of health services revenues and
investment income. The primary uses of cash include medical and other benefit
payments, as well as operating expense payments. Positive cash flows are
invested pending future payments of medical and other benefits and other
operating expenses. Our investment policies are designed to maximize yield,
preserve principal and provide liquidity to meet anticipated payment
obligations.


     Our operating cash flow improved during the first quarter of 2002 in
comparison with the first quarter of 2001. Cash used in continuing operations
improved from $21.1 million for the three months ended March 31, 2001 to $9.9
million for the three months ended March 31, 2002. This reflects improved
operating results in the insured medical, self-funded and government
intermediary services segments and a reduction of premium and other operating
receivables. The primary reason that operating cash flows still remained in an
overall negative position for the first quarter of 2002 despite the improvement
in operating results is the run-out of year-end 2001 claim reserves for the HMO
membership, which decreased by 24.4% during the quarter, and the exit from the
Medicare+Choice business effective January 1, 2002. Cash provided by investing
activities for the three months ended March 31, 2002 includes proceeds of $18.2
million from the sale of 1.4 million shares of AMSG common stock and $17.0
million in cash proceeds received from the sale of Innovative Resource Group.
Cash provided by investing activities for the three months ended March 31, 2001
reflects the acquisition of UWS, which added $50.0 million to our cash and cash
equivalents balance. Cash provided by discontinued operations of $0.5 million
for the three months ended March 31, 2002 reflects the first quarter results of
Innovative Resource Group.


     To meet periodic cash flow requirements, we make borrowings under our bank
line of credit. The line of credit is with a commercial bank and has an interest
rate equal to the London Interbank Offered Rate, or "LIBOR," plus 1.5%, adjusted
monthly with interest payments due monthly. The line of credit permits aggregate
borrowings among certain subsidiaries, excluding the corporate holding company,
up to $20.0 million. At March 31, 2002, the outstanding balance on this line of
credit was $6.3 million. The line of credit terminates, and all borrowings then
outstanding are due, on December 31, 2002.

     In addition, we have a term business note for the corporate holding company
with a commercial bank for $7.5 million, which originated on December 31, 2001.
The term note balance remained at $7.5 million as of March 31, 2002. The term
note has a rate of interest equal to LIBOR plus 1.5%, with payment of principal
and interest due in quarterly installments beginning June 30, 2002 and ending
June 30, 2003. We intend to repay this note in full with proceeds from this
offering.

     Interest expense on the bank line of credit and the term business note
discussed above totaled $0.2 million for the three months ended March 31, 2002.
There was no interest expense on debt for the three months ended March 31, 2001.
Management is in negotiations with commercial banks to obtain a $30 million
credit facility for the Cobalt holding company. We may use proceeds from this
credit facility

                                        37


to repay a portion of the $70 million intercompany note issued by Cobalt to
BCBSUW and described below.

     The Association requires BCBSUW and CompcareBlue to maintain a prescribed
liquidity ratio of certain liquid assets to average monthly expenses, as
defined, in accordance with licensure requirements of the Association. BCBSUW
and CompcareBlue maintained these required levels as of March 31, 2002.

     Our investment portfolio consists primarily of investment-grade bonds and
government securities and has a limited exposure to equity securities. At March
31, 2002, $212.2 million or 98.3% of our total investment portfolio was invested
in bonds. The bond portfolio had an average quality rating by Moody's Investor
Service of "Aa2" at March 31, 2002. At March 31, 2002, $204.8 million or 94.9%
of our total investment portfolio was classified as available-for-sale. The
market value of the total investment portfolio, which includes stocks and bonds,
was less than amortized cost by $2.0 million at March 31, 2002.

     At December 31, 2001, $188.1 million or 98.1% of our total investment
portfolio was invested in bonds compared with $30.0 million or 67.5% at December
31, 2000. The bond portfolio had an average quality rating by Moody's Investor
Service of "Aa3" at December 31, 2001 and December 31, 2000. At December 31,
2001, $180.7 million or 94.3% of our total investment portfolio was classified
as available-for-sale compared with $44.4 million or 100.0% as of December 31,
2000. The market value of the total investment portfolio, which includes stocks
and bonds, was greater than amortized cost by $0.3 million and $0.2 million at
December 31, 2001 and December 31, 2000, respectively.

     Unrealized gains and losses on bonds classified as available-for-sale are
included as a component of surplus, net of applicable deferred taxes. We have no
investments in mortgage loans, no non-publicly traded securities (except for
investments related to our affiliates), real estate held for investment or
financial derivatives (except for principal-only strips of U.S. Government
securities).

     We have an outstanding line of credit in the amount of $15.0 million as of
March 31, 2002 available to Health Professionals of Wisconsin, Inc., an
affiliate of University Healthcare, Inc., which is a key provider for Unity. The
balance was $3.0 million as of March 31, 2002. Interest on the line of credit is
calculated using the prime rate.

     We have a note receivable from APS Healthcare Bethesda, Inc. for $10.0
million originated on March 29, 2002 related to the sale of Innovative Resource
Group. The note bears an interest rate of prime plus 3.5% and has a term of
three years.

     As of September 11, 1998, UWS entered into a $70 million note obligation
due to BCBSUW in connection with the spin-off in 1998 of AMSG's managed care
companies and specialty business. We pledged the common stock of our
CompcareBlue subsidiary as collateral for the note obligation. Interest is
payable quarterly at a rate equal to 9.75% and 8.06% as of December 31, 2001 and
2000, respectively. The original maturity date of the principal balance was
extended from April 30, 2001 to January 1, 2002. The maturity date was
subsequently extended to February 15, 2002 at an interest rate of 7.38%. The
note was amended and the maturity date was extended to January 2, 2003 at an
interest rate of 7.38% on February 14, 2002. Effective with the Combination, the
principal amount of this note, together with all related interest expenses, are
eliminated in consolidation.

     In addition, as of March 31, 2002, we had $22.6 million in outstanding
obligations to UWIC, secured by the stock of certain of our subsidiaries, which
we intend to pay in full with the proceeds of this offering.

     In 2001, we entered into an engagement letter with an investment bank to
provide advisory services in connection with potential financial transactions.
We terminated this relationship in March 2002. The engagement letter provided
that we pay a fee in respect of a transaction effected within twelve months of
termination (or later if an agreement regarding the transaction was entered into
within twelve months after termination) equal to the greater of $3.5 million or
a percentage of the transaction value (as defined). This fee obligation could be
claimed to extend to one or more of our asset dispositions effected in 2002, to
this offering and to subsequent transactions. No such claim has been made, and
we would dispute any claim, should one be made.

                                        38



     Under the OCI order issued in connection with the Combination, we are
required to obtain the approval of the OCI prior to any issuance of our common
stock. This approval is required until the OCI determines that its oversight is
no longer necessary to protect the Foundation against improper dilution of its
equity interest.


STATUTORY CAPITAL

     We are required to maintain certain levels of statutory capital and surplus
under the NAIC Risk Based Capital requirements. Wisconsin insurers are also
subject to compulsory and security surplus requirements based upon a percentage
of underwritten premiums, with the applicable percentage determined by line of
business. In addition to statutory capital requirements, we, BCBSUW and
CompcareBlue are required to maintain certain capital levels as determined by
the Association.

MANAGEMENT'S PLAN

     Operating losses incurred during 1999 through 2001 reduced the statutory
surplus of our insurance subsidiaries. Despite these operating losses and the
implementation of changes in statutory accounting effective January 1, 2001, we
complied with minimum capital and liquidity requirements of the OCI and the
Association during 1999, 2000 and 2001. We maintained compliance, in part, by
contributing regulated and non-regulated subsidiaries to regulated entities and
by collateralizing certain intracompany debt obligations with the common stock
of affiliated entities. Following a review by the OCI of these intracompany
transactions, we agreed with the OCI as to how these transactions should be
treated for surplus and capital calculations. In addition, at the request of the
OCI, we prepared a plan of action to satisfy these intracompany obligations and
strengthen our capital to assure that our insurance subsidiaries continue to
satisfy the minimum capital and liquidity requirements of the OCI and the
Association.

     The outstanding common stock of CompcareBlue, Unity, Valley and United
Heartland, Inc. currently provides the collateral for approximately $93 million
borrowed by us from BCBSUW and UWIC. These intracompany balances have been
eliminated in our consolidated balance sheets. However, the intracompany
balances continue to be an obligation of us to BCBSUW ($70 million) and UWIC
(approximately $22.6 million) in the statutory-basis financial statements of
BCBSUW and UWIC. We are obligated by the terms of the debt instruments and by
the OCI to repay the $70 million obligation to BCBSUW by January 2, 2003 and the
$22.6 million obligation to UWIC by September 30, 2002. Alternatively, we could
transfer the pledged collateral to BCBSUW and UWIC to satisfy the legal
obligations, but that would not assist BCBSUW in complying with minimum capital
and liquidity requirements, since the minimum capital calculations for
investments in subsidiaries generate a greater capital requirement than for
cash, marketable securities or affiliated receivables.

     The capital plan, which management has provided to and discussed with the
OCI and the Association and which we are currently implementing, included the
following action steps to maintain required capital and liquidity levels:

     - Sell certain non-regulated subsidiaries owned by us for cash and/or notes
       prior to October 1, 2002. On March 29, 2002, we sold our behavioral
       health and medical management subsidiary, Innovative Resource Group, LLC,
       for $27 million, of which $17 million was received in cash.

     - Reduce BCBSUW's investment in AMSG common stock from 45% of the shares
       outstanding to less than 20% through public or private offerings during
       2002. We have reduced our investment in AMSG to 15% as of June 4, 2002,
       raising approximately $69 million for BCBSUW.

     - Obtain debt financing at our corporate holding company from one or more
       institutional lenders to fund holding company liquidity needs including
       the repayment of the collateralized intracompany debt obligations between
       the holding company and its regulated subsidiaries. We are currently
       negotiating a $30 million revolving credit facility with a commercial
       bank.

     - Achieve our 2002 projected core earnings, which anticipate breakeven
       operating results for CompcareBlue for the year ending December 31, 2002
       as compared to an operating loss of
                                        39


       $32.5 million for the year ended December 31, 2001. Management expects
       CompcareBlue's significant change in profitability to occur as a result
       of efforts in the fourth quarter of 2001 to cancel unprofitable business
       and implement necessary premium increases for the remaining business. We
       achieved our first quarter 2002 projected core earnings, including
       progress toward obtaining breakeven results for CompcareBlue by the end
       of 2002.

     In addition, we have agreed with the OCI that we will not enter into
certain intercompany transactions, including loans, guarantees, reinsurance
arrangements, and other operational and financial arrangements, and our
insurance subsidiaries are prohibited from paying any dividends, without the
approval of the OCI. We have also agreed to adhere to certain practices in
conducting and accounting for affiliate transactions, notably involving the
lending practices previously described. We will not use uncollateralized,
non-operating intercompany balances in complying with minimum capital and
liquidity requirements. We have reflected the revised practices in the December
31, 2001 regulated subsidiary statutory-basis financial statements filed with
the OCI and other regulatory agencies. We have also agreed not to enter into any
new reinsurance arrangements with third parties without the approval of the OCI.

     Our insurance subsidiaries are currently in compliance with the capital
requirements calculated as required by the OCI. We expect our insurance
subsidiaries to maintain compliance throughout 2002 by substantially completing
the capital plan described above or transactions with an equivalent impact on
our position relative to minimum capital and liquidity requirements.
Non-compliance with minimum capital and liquidity requirements or any of the
requirements described above may subject us to various regulatory actions by the
OCI, including, among others, revocation of our licenses to sell insurance
products in Wisconsin and placing us under state regulatory control. See
"Business -- Regulation -- Capital Requirements." In addition, the Association
has termination rights if our subsidiary licensees' capital falls below the
lowest licensure minimum capital levels established by the Association. See
"Business -- Blue Cross and Blue Shield Licenses."

INFLATION

     Health care costs have been rising and are expected to continue to rise at
a rate that exceeds the consumer price index. Our cost control measures,
risk-sharing incentive arrangements with medical care providers, and premium
rate increases are designed to reduce the adverse effect of medical cost
inflation on our operations. In addition, we utilize our ability to apply
appropriate underwriting criteria in selecting groups and individuals and in
controlling the utilization of health care services. However, we cannot assure
you that these efforts will fully offset the impact of inflation or that premium
revenue increases will equal or exceed increasing health care costs.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Our discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses, and related disclosure of contingent assets and
liabilities. On an on-going basis, we evaluate our estimates, including those
related to allowances for doubtful accounts, deferred tax assets, impairment of
equity method investments, goodwill impairment, medical and other benefits
payables, and litigation and tax contingencies. We base our estimates on
historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

  ALLOWANCE FOR DOUBTFUL ACCOUNTS

     A significant portion of our receivable balances result from balances due
from small and large employers, individuals, and providers of medical services.
We maintain allowances for doubtful accounts

                                        40


for estimated losses resulting from the inability of our customers to make
required payments or retroactivity in reporting membership cancellations. If the
financial condition of our customers were to deteriorate or if significant
employee turnover were to occur among insured employers, resulting in an
impairment of their ability to make payments, additional allowances may be
required.

  DEFERRED TAX ASSETS

     We recorded a full valuation allowance against all of our net deferred tax
assets as of March 31, 2002 and December 31, 2001. Management deemed that a full
valuation allowance was appropriate based on an analysis, which concluded that
these assets are not more likely than not to be realized. We considered future
taxable income and ongoing prudent and feasible tax planning strategies in
assessing the need for the valuation allowance. In the event we were to
determine that we would be able to realize our deferred tax assets in the future
in excess of our net recorded amount, an adjustment to the deferred tax asset
would increase income or reduce recorded goodwill in the period such
determination was made.

  IMPAIRMENT OF EQUITY METHOD INVESTMENTS


     Prior to the reduction of our ownership of AMSG common stock to 15% on June
4, 2002, our investment in AMSG was accounted for under the equity method of
accounting. At December 31, 2001, we owned 6,309,525 shares of the outstanding
common stock (45% ownership) of AMSG. Our per share carrying value as of
December 31, 2001 was $16.44 based on our share of AMSG's equity. Pursuant to
current accounting principles generally accepted in the United States, we wrote
down our investment in AMSG to the current market value of such stock ($12.45 as
of December 31, 2001) as a charge to operations due to our evaluation and
announcement that our holdings in AMSG no longer represented a strategic
investment and that we planned an orderly reduction of its ownership. Effective
upon the reduction of our ownership of AMSG common stock to 15%, we changed our
accounting for our investment in AMSG from the equity method to the fair value
method. Under the fair value method, our investment in AMSG is recorded at
market value, with any changes in market value being recorded as an unrealized
gain or loss.


  GOODWILL IMPAIRMENT

     In assessing the recoverability of our goodwill and other intangibles we
must make assumptions regarding estimated future cash flows and other factors to
determine the fair value of the respective assets. If these estimates or their
related assumptions change in the future, we may be required to record
impairment charges for these assets not previously recorded. On January 1, 2002,
we adopted Statement of Financial Accounting Standards No. 142, "Goodwill and
Other Intangible Assets," and will be required to analyze our goodwill for
impairment issues during the first six months of fiscal 2002, and then on a
periodic basis thereafter. During the year ended December 31, 2001, we did not
record any impairment losses related to goodwill and other intangible assets.

  MEDICAL AND OTHER BENEFITS PAYABLES

     The amount of medical and other benefits payables (the "loss reserves") is
determined based on an estimation process that is very complex and uses
information obtained from both company specific and industry data, as well as
general economic information (e.g., medical cost index). The estimation process
requires us to continuously monitor and evaluate the life cycle of claims, on
type-of-business and nature-of-claim bases. Using data obtained from this
monitoring and assumptions about the emerging trends, we develop information
about the size of ultimate claims based on historical experience and other
available market information. The most significant assumptions, which vary by
class of business, used in the estimation process include determining the trend
in loss costs, the expected consistency in the frequency and severity of claims
incurred but not yet reported to prior year claims, changes in the timing of the
reporting of losses from the loss date to the notification date, and expected
costs to settle unpaid claims. We also monitor the reasonableness of the
judgments made in the prior year estimation process (referred to as a hindsight
analysis) and adjust current year assumptions based on the hindsight analysis.
                                        41


     Because the amount of the loss reserves is sensitive to assumptions, we do
not totally rely on a single estimate to determine the loss reserve. To test the
reasonableness of the best estimate generated by our loss estimation process, we
develop several estimates using generally recognized actuarial projection
methodologies that result in a range of reasonably possible loss reserve
outcomes that are used to challenge our best estimate. We will continue to
closely monitor these developments to ensure that our conclusions on the impact
are appropriate. Should other trends emerge, we would react accordingly which
could result in upward adjustments to our reserves and a corresponding charge to
earnings. Another factor that can significantly impact the loss reserve estimate
is the impact of legislative changes in health care, court resolutions and
judicial interpretations. We only factor into our assumptions actual legislative
changes, court rulings and interpretations. Therefore, the loss reserve
estimates made can be significantly impacted by future legislative actions,
rulings or interpretations.

  LITIGATION AND TAX CONTINGENCIES

     We and our affiliates are involved in various legal actions occurring in
the normal course of business. In the opinion of management, we have made
adequate reserves for losses which may result from these actions. It is
possible, however, that future results of operations for any particular
quarterly or annual period could be materially affected by changes in our
assumptions related to these proceedings. As discussed in Note 14 of our audited
consolidated financial statements, as of December 31, 2001, we have accrued our
best estimate of the probable cost for the resolution of these claims. This
estimate has been developed in consultation with internal and outside legal
counsel that is handling our defense in these matters and is based upon a
combination of litigation and settlement strategies. To the extent additional
information arises or strategies change, it is possible that our best estimate
of its probable liability in these matters may change. We recognize the costs of
legal defense in the periods incurred. Accordingly, the future costs of
defending claims are not included in our estimated liability.

     We frequently face challenges from domestic tax authorities regarding the
amount of taxes due. These challenges include questions regarding the timing and
amount of deductions and the allocation of income. In evaluating the exposure
associated with our various filing positions, we record reserves for probable
exposures when identified. Based on our evaluation of our tax positions, we
believe we have appropriately accrued for probable exposures. To the extent we
were to prevail in matters for which accruals have been established or be
required to pay amounts in excess of its reserves, our effective tax rate in a
given financial statement period may be materially impacted.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Because of our investment policies, the primary market risks associated
with our portfolio are interest rate risk, credit risk and the risk related to
fluctuations in equity prices. With respect to interest rate risk, a reasonably
near-term rise in interest rates could negatively affect the fair value of our
bond portfolio. However, because we consider it unlikely that we would need or
choose to substantially liquidate our portfolio, we believe that such an
increase in interest rates would not have a material impact on future earnings
or cash flows. In addition, we are exposed to the risk of loss related to
changes in credit spreads. Credit spread risk arises from the potential that
changes in an issuer's credit rating or credit perception may affect the value
of financial instruments.

     The overall goal of the investment portfolio is to support our ongoing
operations. Our philosophy is to manage assets to maximize total return over a
multiple-year time horizon, subject to appropriate levels of risk. We manage
these risks by establishing gain and loss tolerances, targeting asset-class
allocations, diversifying among asset classes and segments within various asset
classes, and using performance measurement and reporting.

     We use a sensitivity model to assess the interest rate risk of our fixed
income investments. The model includes all fixed income securities and
incorporates assumptions regarding the impact of changing interest rates on
expected cash flows for certain financial assets with prepayment features, such
as callable bonds and mortgage-backed securities. Since December 31, 2001, no
significant changes have occurred in the determination of the reduction in fair
value of our modeled financial assets as a result of a hypothetical
instantaneous 100 basis point increase in market interest rates.

                                    BUSINESS

OVERVIEW

     We are the leading managed care company in Wisconsin, offering a broad
portfolio of managed care and insurance products to employers, individuals and
government entities. We have an exclusive license to utilize the Blue Cross and
Blue Shield service marks in Wisconsin, giving us a unique position in that
market. As of March 31, 2002, we serviced approximately 605,000 lives in our
health insurance operations and approximately 343,000 lives in our dental
insurance programs.

     BCBSUW provides underwritten products, including preferred provider
organizations (PPO) and indemnity options, as well as self-funded,
administrative services only programs. CompcareBlue operates the oldest HMO in
Wisconsin.


     We offer the largest provider network in Wisconsin. All of our customers,
including HMO members, have the ability to access the leading physicians and
hospitals in their respective service areas, including Mayo Health Systems,
University Health Care and Aurora Health Care. We believe that our ability to
offer a full spectrum of products and a broad provider network to meet the needs
and objectives of a wide range of customers provides us with a competitive
advantage.


     We offer a variety of specialty managed care products, including dental,
life and disability insurance. We are one of the largest providers of dental HMO
and dental indemnity coverage in Wisconsin. We also offer workers' compensation
insurance and a variety of specialty managed care services, including cost
containment, health care electronic data interchange and receivables management
services. These specialty products and services are designed to complement our
customers' employee benefit packages. We also process Medicare claims as a
Medicare Part A fiscal intermediary and a Regional Home Health intermediary for
providers in numerous states and several U.S. territories and as a national
intermediary for the Federally Qualified Health Centers in all 50 states.

     We market our medical and dental products through a salaried sales force
located throughout Wisconsin, as well as through independent agents and brokers,
and directly to customers via the internet. By integrating the marketing of our
medical products, we are able to offer a broad range of product choices to
health care consumers. We sell our specialty managed care products and services
through a variety of distribution channels to employer groups and providers,
principally in Wisconsin.

OUR STRATEGY

     Over the past two years, we have taken certain steps that have resulted in
significant increases in profitability, including discontinuing unprofitable
business lines; repricing or terminating unprofitable customer contracts;
improving underwriting techniques and pricing products appropriately to reflect
underlying cost trends; negotiating improved terms in our provider contracts and
bolstering management in key areas, including in our Milwaukee market. We intend
to continue to pursue improvements in our operating results through the
implementation of the following strategies:

     - Capitalize on the Strength of the Blue Cross Brand.  We believe that our
       right to the exclusive use of the Blue Cross and Blue Shield brands in
       Wisconsin gives us a significant marketing advantage, and we intend to
       continue emphasizing these brands among prospective customers and
       members. According to the Association, the number of members insured by
       plans bearing the Blue Cross and Blue Shield brands has increased by
       approximately 26% nationwide since 1995. We further intend to leverage
       the strength of the Blue Cross and Blue Shield brands on a national basis
       by participating in the Association's BlueCard PPO program, a network of
       Blue Cross and Blue Shield plans. The BlueCard PPO program allows us to
       compete with national health insurers for groups with employees outside
       of the Wisconsin market and provides our members and members of other
       Blue Cross and Blue Shield affiliates the opportunity to access care
       while away from home.

     - Focus on Core Business.  We have made a strategic decision to focus on
       our core Blue Cross and Blue Shield branded and HMO businesses, where we
       believe significant opportunities exist for
                                        43



       earnings growth. These businesses together produced over 80% of our
       revenues and approximately 59% of our pre-tax operating income in the
       quarter ended March 31, 2002. On March 29, 2002, we sold our behavioral
       health and medical management subsidiary, Innovative Resource Group, LLC,
       for $27 million. In the future, we may sell other non-core specialty
       businesses. In addition, since March 1, 2002 we have reduced our
       ownership of our former affiliate AMSG, a small group and individual
       health insurer, from approximately 45% to approximately 15% of AMSG's
       outstanding common stock, raising net proceeds of approximately $69
       million and relieving us of a significant portion of our capital
       requirement relating to AMSG.


     - Expand Operating Margins and Realize Operating Efficiencies.  We intend
       to focus on expanding operating margins in our core businesses by
       improving underwriting techniques and product design, pricing products
       appropriately to reflect underlying cost trends, discontinuing
       unprofitable businesses and contracts, and improving provider
       arrangements. We intend to pursue additional operating efficiencies
       through consolidation of administrative functions, including combining
       the administrative functions of BCBSUW and CompcareBlue as well as the
       administrative functions of certain of our specialty businesses.

     - Increase Market Share.  We intend to focus on increasing market share in
       Wisconsin through an increased emphasis on our core business, the
       BlueCard PPO program and our Medicare supplement product offerings, as
       well as the introduction of new products. We expect to accomplish this by
       leveraging our diverse customer base by cross-selling product offerings,
       and pursuing opportunistic acquisitions of health insurers in Wisconsin.

PRODUCTS AND SERVICES

  INSURED AND SELF-FUNDED MEDICAL PRODUCTS

     We offer a wide range of insured and self-funded medical products,
including HMOs, PPOs, point of service (POS) plans, indemnity products, and
Medicare supplement products. We design our products to meet the needs and
objectives of a wide range of customers, including employers, individuals, and
government entities. Our customers either contract with us to assume
underwriting risk or self-fund underwriting risk and rely on us for network
management and administrative services. Our products vary with respect to the
level of benefits provided, the costs to be paid by employers and members,
including deductibles and copayments, and the extent to which our members'
access to providers is subject to referral or preauthorization requirements.

     We provide our Blue Cross and Blue Shield branded products through BCBSUW
and our Blue Cross and Blue Shield branded HMO, CompcareBlue, which operates
primarily in the Milwaukee metropolitan area. We also provide private branded
products through our HMO subsidiaries, Valley and Unity. Valley operates
primarily in northwestern Wisconsin, including the city of Eau Claire, whereas
Unity operates primarily in south central and southwestern Wisconsin, including
the city of Madison.


     We also participate in the BlueCard PPO program, a national network of Blue
Cross and Blue Shield plans. The BlueCard PPO program permits members of our
Blue Cross and Blue Shield branded health plans to receive health care services
from providers in the networks of other Blue Cross and Blue Shield plans. This
allows us to compete with national health insurers for groups with employees
outside the Wisconsin market. This also allows members to access care while away
from home. Through electronic communications the "host" plan verifies
eligibility, pays the claim based on its local fee arrangement and is then
reimbursed by the "home" plan for the claim as well as an administrative fee.
Absent an agreement between two plans, the Association determines the amount of
the administrative fee. Under this arrangement, we are also able to generate
revenue from provider network management and claims repricing.


                                        44


     As of March 31, 2002, our health plan membership consisted of the following

  SPECIALTY MANAGED CARE PRODUCTS AND SERVICES

     We are the largest provider of dental coverage in Wisconsin. Dental HMO
coverage is offered through CompcareBlue, and dental indemnity coverage is
offered through BCBSUW. These dental HMO and indemnity benefit products are
currently marketed under the DentalBlue(R) brand name. As of March 31, 2002 we
had approximately 307,000 insured dental members and approximately 36,000
self-funded dental members.

     We offer group term life and accidental death and dismemberment coverages
as well as dependent life benefits. Short and long-term disability products
provide income replacement for an employee who becomes disabled through a
non-work related event. As of March 31, 2002, we insured approximately 120,000
disability members and 148,000 life members.

     We provide worker's compensation insurance products and managed care
services to employees in Wisconsin. We also provide cost containment services,
including hospital bill audit, provider discount network repricing,
negotiations, diagnosis-related group validation, claims administration audit,
subrogation and recovery, electronic audit, collection and fraud investigation
and recovery services to assist customers in reducing their expenses and provide
more cost effective health care delivery. Additionally, we provide software and
claim submission services for Medicare, Medicaid, private insurers, third party
administrators and re-pricers. We also provide collections and receivables
management services to hospitals and other commercial clients. We generally
provide these specialty managed care products and services through wholly-owned
subsidiaries.

  GOVERNMENT INTERMEDIARY SERVICES


     We provide health care program administration and program safeguard
services for the Centers for Medicare & Medicaid Services, which we refer to as
"CMS." In connection with providing these services, we serve as the Medicare
Part A Intermediary and Regional Home Health Intermediary for numerous states
and territories, and serve as the national Intermediary for the Federally
Qualified Health Centers in all 50 states. In addition to providing services to
the Medicare program, we also provide claim processing and administrative
services in conjunction with the Wisconsin Medicaid program and the Health
Insurance Risk Sharing Plan.


     The Association contracts with CMS to process Medicare Part A claims. We
have subcontracted with the Association to provide those services in various
states and territories. Until May 2002, that subcontract was held by BCBSUW,
which further subcontracted those services to our wholly-owned subsidiary,
United Government Services, LLC.


     In May 2002, BCBSUW was granted a contract novation by CMS, enabling BCBSUW
to transfer the Medicare contract to United Government Services. We are the
first Medicare Part A processor to receive such a novation, and it is our
understanding that we received the novation based on the strength of our
compliance program. The novation provides for certain limitations on our
liability relating to acts


                                        45



subsequent to the novation. Also, the novation effectively allows us to transfer
the Medicare Part A processing business through the sale of United Government
Services to another Blue Cross and Blue Shield plan, should we determine to do
so. Congress is currently considering legislation which, if passed, would allow
us to sell United Government Services to any third party, including one that is
not a Blue Cross and Blue Shield plan, should we determine to do so. The
legislation is intended to increase competition for government contracts for
processing claims for the Medicare program. Our United Government Services
subsidiary is a fiscal intermediary for the Medicare program. Such legislation,
if adopted, could result in further competition for Medicare contracts.


SALES AND MARKETING

     Marketing group health insurance products is generally a two-step process.
Presentations are made first to employers. Once selected by an employer, we then
directly solicit members from the employee base. During periodic "open
enrollments," when employees are permitted to change health care programs, we
use advertising and work site presentations to attract new members. Virtually
all of the group contracts are renewable annually.

     Significant factors in product selection by employers and employees include
the composition of provider networks, quality of services, price, choice and
scope of benefits, and market presence. To the extent permitted by the OCI and
the federal government, we can offer an employer a wide spectrum of benefit
options, including federally qualified and non-federally qualified products. To
address rising health care costs, some employers now consider a variety of
health care options to encourage employees to use the most cost-effective form
of health care services.

     We market our medical and dental products through a salaried sales force
located throughout Wisconsin, as well as through independent agents and brokers,
and directly to customers via the internet. By integrating the marketing of our
insured health and specialty managed care products and services, we are able to
offer a wide range of products and services to our customers. We sell our
specialty managed care products and services through a variety of distribution
channels to employer groups and providers, primarily in Wisconsin.


     While our traditional sales and marketing efforts have yielded significant
gains within our insured medical/self-funded and specialty businesses
individually, we believe that a more coordinated cross-selling effort could
significantly increase our market share across our business lines.


     Our pricing strategy is targeted to cover current and anticipated changes
in health care costs and operating costs and deliver budgeted returns on
investment. To that end, in May 2002, we transferred primary responsibility for
our underwriting department to our Chief Actuary. We believe that the active
role our actuarial staff plays in the underwriting process will allow us to grow
our business while effectively managing the financial risks associated with our
products.

OUR PROVIDER NETWORK


     BCBSUW offers one of the largest provider networks in Wisconsin and
provides a diverse selection of primary care and specialty care physicians to
meet the health care needs of our members. CompcareBlue has an extensive
provider network in southeastern Wisconsin, and is the only HMO that contracts
with all eight of the largest multi-specialty clinics in Milwaukee, including
Aurora Health Care, the largest multi-specialty provider in Wisconsin, for the
provision of health care services to its members.


     A majority of Valley's medical and other benefits are provided under an
arrangement with Midelfort Clinic, Ltd. and its affiliate, Luther Hospital,
which are affiliated with Mayo Health Systems and which we believe are the
leading medical service providers in Eau Claire, Wisconsin. Unity contracts with
Community Physicians' Network, an independent physician association, and
University Health Care, Inc. University Health Care contracts on behalf of the
University of Wisconsin Hospital and Clinics, the University of Wisconsin
Medical Foundation and the University of Wisconsin School of Medicine.

                                        46


Community Physicians' Network and University Health Care provide the majority of
physician services for Unity's membership throughout its 19 county service area.

     All of our HMOs have received National Committee for Quality Assurance, or
"NCQA," accreditation and higher than average satisfaction scores on clinical
services. As a result of our aggressive credentialing efforts, the percentage of
our HMO practitioners who are board certified is at or above the NCQA averages.

     BCBSUW contracts primarily on a discounted fee-for-service basis. In
fee-for-service arrangements, risks associated with utilization are retained by
us. However, such arrangements provide us with greater pricing flexibility and
opportunities to benefit by application of underwriting on a group-specific or
individual basis. Furthermore, fee schedule-based compensation allows us to
better target improvement in loss ratios through product development, benefit
modification and medical management. CompcareBlue, Valley and Unity manage the
cost of health care provided to members through the method of payment and
risk-sharing programs with physician groups and hospitals and through their
respective utilization management programs. The method of payment consists of a
combination of capitation, fee schedules and discounted fee-for-service
arrangements. Capitation is an arrangement whereby we pay medical providers a
set fee per member per month in exchange for providing health care services.

     Approximately 28% of the medical benefits provided by CompcareBlue, Valley
and Unity were provided under capitated arrangements in 2000. In 2001, this
number decreased to 17%, and in the first quarter of 2002, this number increased
to 22%, primarily as a result of a decline in CompcareBlue's membership.

     Pursuant to the arrangements between Valley and Midelfort, Midelfort has an
option to repurchase all the capital stock of Valley on December 31, 2002 for
Valley's net equity plus $0.4 million. This repurchase option must be exercised
by Midelfort, if at all, by September 1, 2002. If Midelfort exercises its
repurchase option, we would have no ongoing interest in Valley.

     Recently, Valley and Midelfort have agreed in principle on the key terms of
a three-year extension of the arrangement. The extension is expected to grant
Midelfort a similar option to repurchase the capital stock of Valley and will
eliminate profit sharing between the parties.

     Pursuant to the provider agreements between Unity and Community Health
Systems, LLC and University Health Care, Community Health Systems has the
option, exercisable on December 31, 2004, to repurchase its proportionate share
of Unity for the current net worth of the business being repurchased. University
Health Care has the option, also exercisable on December 31, 2004, to purchase
its share of Unity for $0.5 million plus the proportionate share of the net
worth of Unity attributable to the University Health Care business, less any
unpaid amount of a maximum performance bonus specified in the agreement.
Exercise of the repurchase option ends the agreement with respect to that party.
If both repurchase options are exercised, we would have no ongoing interest in
Unity.

MEDICAL MANAGEMENT

     We utilize a broad range of focused, traditional cost containment and
advanced care management processes across our various product lines, such as
case management, disease management, evidence based medical policy, return on
investment evaluation, targeted opportunities, and quality improvement programs.
Our case management philosophy is built on helping members confront a complex
care system to find the appropriate care in a timely and cost effective manner.
We believe this approach builds positive relationships with providers and
members, and helps us achieve cost savings.

     Our population-based disease management programs attempt to identify
members that have or are at risk to develop high cost chronic diseases and
conditions. These members typically have high utilization of health care
services, which can result in significant costs. By identifying high risk
members and enrolling them in specialized programs involving patient education,
lifestyle modification including changes in diet and intensive care management,
we seek to improve patient satisfaction, manage medical costs and

                                        47


improve medical outcomes. These programs include diabetes, congestive heart
failure, asthma, and high risk pregnancy and we plan to expand these in the
future.

     We outsource significant behavioral health, utilization, disease and case
management services to our former subsidiary, Innovative Resource Group, which
we sold in March 2002. Innovative Resource Group manages our local pharmacy
network, customer service and clinical programs. WellPoint Pharmacy Management
manages our pharmacy claims processing and pharmaceutical manufacturer rebates.

MANAGEMENT INFORMATION SERVICES

     Information systems management for our core health business is primarily
delivered under a facilities management agreement with Blue Cross Blue Shield of
South Carolina and Electronic Data Systems Corp., or "EDS." Blue Cross and Blue
Shield of South Carolina is responsible for administering information systems
supporting our claims processing. By working with another plan in the Blue Cross
and Blue Shield system, we are able to leverage system enhancements that support
the interchange of data across Blue Cross and Blue Shield plans, such as the
coordination of provider network arrangements on a national basis. We use EDS
information systems primarily to support our membership enrollment database. Our
specialty businesses use a variety of internal information systems that are
specifically designed for various product lines. Our agreement with Blue Cross
Blue Shield of South Carolina is in effect until October 2005, and our agreement
with EDS is in effect until October 2003.


     In 1999, and again in 2002, we received a letter from the holder of a
patent asserting that certain of our information systems, including our claims
processing systems, infringe this patent. We are reviewing the merits of this
assertion. If we are found to infringe this patent, we could be required to
discontinue the infringing activity, which could disrupt our operations, and
could be required to pay damages for past activities and pay royalties for
future use, which could be substantial. As to certain of our systems that have
been claimed to infringe the patent, we have a contractual right to
indemnification from the vendor of the systems for losses resulting from patent
infringement. However, we cannot assure you that the indemnification would be
sufficient to protect us in the event that a patent infringement claim is made
against us and is determined to be valid.


COMPETITION

     The managed care industry is highly competitive. We believe the principal
competitive features affecting our ability to retain and increase our membership
include the strength of the Blue Cross and Blue Shield brands, our ability to
offer our customers a broad continuum of insured and self-funded products and
access to a network of high quality providers. Portions of the Wisconsin market
are dominated by a small number of provider-owned health plans, with a
correspondingly large influence on the markets in which we compete. We may
experience increased competition in the future, and provider-owned health plans
can often obtain favorable financial arrangements which are not available to us.
Some of our competitors are larger, have considerably greater financial
resources and distribution capabilities and offer more diversified types of
insurance coverage than us. Our key competitors include Humana, Inc., United
Healthcare, Dean Health Plan, Physicians Plus and Wisconsin Physician Service.

BLUE CROSS AND BLUE SHIELD LICENSES

     We are a licensee of the Blue Cross Blue Shield Association. The
Association is a national trade association of Blue Cross and Blue Shield
licensees which strives to promote and preserve the integrity of the Blue Cross
and Blue Shield names and service marks as well as provide certain coordination
among plan and provider services. As a licensee of the Association, we have the
exclusive right to use the Blue Cross and Blue Shield names and service marks
for all of our products in Wisconsin.


     The licenses require us to pay an annual fee to the Association equal to
total association expenses allocated to Association members based upon
enrollment and premium. Each Association licensee is an independent legal
organization and is not responsible for obligations of other Association member
organizations. We do not have the right to use the Blue Cross and Blue Shield
names and service marks outside of our Blue Cross and Blue Shield service area,
except in certain limited circumstances.

                                        48


     Each of BCBSUW, CompcareBlue and UGS is also a licensee of the Association,
by virtue of being a controlled affiliate of Cobalt. As required by the
Association, Cobalt has provided each of BCBSUW and CompcareBlue a guarantee of
their contractual and financial obligations to their customers. We have also
agreed to indemnify the Association and other Blue Cross and Blue Shield plans
against any claims asserted against such entities resulting from our activities
as well as the activities of any of our Blue Cross and Blue Shield licensed
affiliates.

     Our license agreements require us to pay the Association a specific amount
upon termination of the license agreements, subject to certain limited
exceptions. The amount payable upon termination of our license agreement is
equal to the product of $25 multiplied by the number of our members receiving
products or services sold or administered under the Blue Cross or Blue Shield
names or service marks, subject to reduction to the extent the payment of the
fee would cause us to fall below certain capital requirements established by the
Association.


     The Association could terminate our license agreements if we do not satisfy
its financial and service performance requirements or if other events described
in the license agreements, some of which are outside of our control. Termination
events include, but are not limited to:


     - failure to meet capital and liquidity requirements of the Association
       (which are in addition to those required by state regulatory agencies);

     - violation of the ownership limitations contained in our Amended and
       Restated Articles of Incorporation and described in this prospectus;

     - termination of the voting trust and divestiture agreement before the
       Foundation's ownership of our common stock falls to less than 5%;

     - the acquisition of our company without the prior consent of a majority of
       the other disinterested licensees of the Association and a majority of
       the then current weighted vote of the other disinterested licensees of
       the Association;

     - violation of the Foundation's divestiture deadlines;


     - determination by the Association that fewer than 80% of our directors are
       independent; and


     - failure to apply the Blue Cross and Blue Shield brands to medical and
       dental business.

     Our Amended and Restated Articles of Incorporation and Amended and Restated
Bylaws include various provisions required by the Association for its for-profit
licensees. These provisions are designed to protect the independence of the
Association's for-profit licensees from any single stockholder and are described
under "Articles of Incorporation and Bylaws."


     The Association has established three risk-based capital thresholds which
are, in order of increasing seriousness, the "Early Warning Monitoring
Threshold," the "Concern Level Monitoring Threshold" and the licensure minimum.
As of December 31, 2001 Cobalt's, BCBSUW's and CompcareBlue's capital levels
were below the "Concern Level Monitoring Threshold." Because of our financial
performance, the Association has included BCBSUW, CompcareBlue and Cobalt in its
Plan Performance Response Monitoring Process, or "PPRMP." As a result, the
Association has requested that we and those subsidiaries regularly submit
additional interim financial information to the Association. In addition, the
PPRMP monitoring process requires that BCBSUW maintain a prescribed level of
escrowed assets as a financial guarantee for our transactions with other Blue
Cross plans. As of March 31, 2002, approximately $17.2 million of BCBSUW's
invested assets were maintained in escrow for this purpose. The PPRMP monitoring
process also requires that we provide certain notices to the Association
regarding our transactions with other Blue Cross plans. We expect the
Association to terminate the PPRMP requirements after our capital levels improve
above the prescribed monitoring thresholds.


     As of December 31, 2001, BCBSUW and CompcareBlue exceeded the minimum
standard to maintain their licenses by $15.8 million and $7.2 million,
respectively. The Association is entitled to

                                        49


terminate our license agreement with the Association, including the right to use
the Blue Cross and Blue Shield service marks, if we fall below the minimum level
of statutory capital and surplus.

REGULATION

  GENERAL

     Government regulation of employee benefit plans, including health care
coverage, health plans and our specialty managed care products, is a changing
area of law that varies from jurisdiction to jurisdiction and generally gives
responsible administrative agencies broad discretion. To comply with these
regulations, it may be necessary for us to make changes from time to time in our
services, products, structure or operations. Additional government regulation or
future interpretation of existing regulations could increase the cost of our
compliance or otherwise affect our operations, products, profitability or
business prospects.

     Federal legislation has significantly expanded regulation of group health
plans and health care coverage. The laws place restrictions on the use of
pre-existing conditions and eligibility restrictions based upon health status
and prohibit cancellation of coverage due to claims experience or health status.
Federal regulations also prohibit insurance companies from declining coverage to
small employers. Additional federal laws, which took effect in 1998, include
prohibitions against separate, lower dollar maximums for mental health benefits
and requirements relating to minimum coverage for maternity inpatient
hospitalization.

     Increasingly, states are considering various health care reform measures
which, if passed, may limit our ability and our health plans' ability to control
which providers are part of their networks and hinder their ability to manage
utilization and cost effectively. "Patient Protection" laws, which became
effective in Wisconsin in late 1998, established a prudent layperson standard
for coverage of emergency room care and provided extended access to providers
who are no longer part of the plan's network. A number of other states are
considering similar legislation. In addition, the United States House of
Representatives and Senate have each passed separate versions of federal patient
protection legislation which could increase our health plans' administrative
costs and hinder their ability to manage utilization and costs effectively. We
cannot predict whether final legislation will be adopted.

  HIPAA

     HIPAA and its implementing regulations contain provisions requiring
mandatory standardization of certain communications between health plans,
electronic clearinghouses and providers who submit certain health information
electronically. HIPAA and its implementing regulations require health plans to
use specific data content standards, mandate the use of specific identifiers
(e.g., national provider identifiers and national employer identifiers) and
require specific privacy and security procedures. Although the new regulations
will have a significant impact on us, the impact will be no greater than the
impact the regulations will have on other insurance companies across the
country. Impacted companies must comply with that portion of the regulations
relating to privacy by April 14, 2003. The deadline for complying with that
portion of the regulations relating to data content standards has recently been
extended to October 16, 2003, provided the health plan submits a compliance plan
to the Department of Health and Human Services by October 16, 2002, which we
intend to do.

     Final privacy regulations became effective in April 2001, with compliance
for most covered entities required by April 2003. The HIPAA statute provides for
civil and criminal liability for its breach and requires us and our business
partners to use health information in a highly restricted manner, to establish
policies and procedures to safeguard the information, to obtain individual
authorizations for some activities, and to provide certain access rights to
individuals. On March 27, 2002, the Department of Health and Human Services
published proposed revisions to the final privacy rule which will not affect the
compliance date. The cost of compliance with these requirements could have a
material adverse effect on our liquidity, financial condition and results of
operations.

                                        50


  HMOS

     Wisconsin has enacted statutes regulating the activities of HMOs. This
regulation provides for periodic financial reports from HMOs and imposes minimum
capital or reserve requirements. In addition, certain of our subsidiaries are
required by state regulatory agencies to maintain restricted cash reserves
represented by interest-bearing instruments which are held by trustees or state
regulatory agencies to ensure that adequate financial resources are maintained
or to act as a fund for insolvencies of other HMOs in the state.

     As a federally qualified HMO, CompcareBlue must file periodic reports with,
and is subject to periodic review by, the Centers for Medicare and Medicaid
Services.

     Our HMOs which have Medicaid contracts are subject to both federal and
state regulation regarding services to be provided to Medicaid enrollees,
payment for those services and other aspects of the Medicaid program. Medicaid
has in force and/or has proposed regulations relating to fraud and abuse,
physician incentive plans and provider referrals, which may affect our
operations.


     We contract with the Office of Personnel Management ("OPM") to cover
federal employees under the Federal Employees Health Benefit Plan, or "FEHBP."
These contracts are subject to extensive regulation, including complex rules
relating to the premiums charged. OPM has the authority to retroactively audit
the rates charged and may seek premium refunds and other sanctions against
health plans participating in the program. Our health plans that currently
contract, or have contracted in past years, with OPM, are subject to such audits
and have in the past and may in the future be requested to make such refunds.
Given our participation in this federal program, and other federal health care
programs, we have implemented, and place great importance upon, an effective
compliance program.


  CAPITAL REQUIREMENTS

     Our insurance subsidiaries are subject to minimum capital requirements
imposed under the laws of the State of Wisconsin. These laws include minimum
capital requirements calculated under a prescribed compulsory and security
surplus computation, which establishes minimum capital based upon a percentage
of underwritten premiums, with the applicable percentage determined by the line
of business. Wisconsin insurance laws also include minimum capital requirements
based on the Risk Based Capital for Insurers Model Act adopted by the NAIC. The
formula for calculating such risk-based capital requirements, set forth in the
instructions adopted by the NAIC, is designed to take into account asset risks,
insurance risks, interest rate risks and other relevant risks with respect to
the individual insurance company's business. Under these laws, our insurance
subsidiaries must submit a report of their risk-based capital level as of the
end of each calendar year. Insurers having less capital than required by the
risk-based capital model formula will be subject to varying degrees of
regulatory action depending on the level of capital inadequacy. The regulatory
action which may be imposed on an insurer includes requiring the adopting of a
comprehensive financial plan, its examination and the issuance of a corrective
order by the state insurance department, or placing the insurer under state
regulated control.

     At the request of the OCI, we prepared a plan of action in early 2002 for
strengthening the capital position of our insurance subsidiaries. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Management's Plan." Our insurance subsidiaries are currently in
compliance with the minimum capital requirements imposed under Wisconsin law,
calculated as required by the OCI.

     In addition, the Association requires certain of our insurance subsidiaries
to meet certain risk-based capital requirements, which are generally more
stringent than those imposed under Wisconsin law. See "Business -- Blue Cross
and Blue Shield Licenses."

  INSURANCE REGULATION

     Each of our insurance subsidiaries is subject to regulation by the
department of insurance in each state in which it is licensed. Regulatory
authorities exercise extensive supervisory power over insurance companies
relating to the licensing of insurance companies; the amount of capital which
must be maintained; the approval of forms and insurance policies used; the
nature of, and limitation on, an insurance company's investments; periodic
examination of the operations of insurance companies; the form

                                        51


and content of annual statements and other reports required to be filed on the
financial condition of insurance companies; and the establishment of capital
requirements for insurance companies. Our insurance company subsidiaries are
required to file periodic statutory financial statements in each jurisdiction in
which they are licensed. Additionally, such companies are examined periodically
by the insurance departments of the jurisdictions in which they are licensed to
do business.


     We actively market insurance products to Medicare eligible individuals.
Medicare supplement (or Medigap) policies are regulated by the OCI and are the
subject of increasing regulation at the state level, as well as additional
legislation at the federal level. We continue to monitor and alter procedures to
comply with new laws and regulations. During 2001, we were subject to regulation
by the Centers for Medicare & Medicaid Services by virtue of our participation
in the Medicare+Choice program. We exited this program effective January 1,
2002.


     Under Wisconsin law, insurance companies must provide the OCI with advance
notice of any dividend that is more than 15% larger than any dividend for the
corresponding period of the previous year. In addition, the OCI may disapprove
any "extraordinary" dividend, defined as any dividend which, together with other
dividends paid by an insurance company in the prior twelve months, exceeds the
lesser of: (i) 10% of statutory capital and surplus as of the preceding December
31; (ii) with respect to a life insurer, net income less realized gains for the
calendar year preceding the date of the dividend; or (iii) with respect to a
non-life insurer, the greater of (A)(ii) above or (B) the aggregate net income
less realized gains for the three calendar years preceding the date of the
dividend less distributions made within the first two of those three years. Our
insurance subsidiaries are currently not allowed to pay dividends to us without
the prior approval of the OCI.

  INSURANCE HOLDING COMPANY REGULATIONS


     We are a holding company that conducts all of our business through our
subsidiaries and are subject to insurance holding company laws and regulations.
Such insurance holding company laws and regulations generally require
registration with the department of insurance of the holding company's
domiciliary state and the filing of certain reports describing capital
structure, ownership, financial condition, certain intercompany transactions and
general business operations. Various notice and reporting requirements generally
apply to transactions between companies within an insurance holding company
system, depending on the size and nature of the transactions. Certain state
insurance holding company laws and regulations require prior regulatory approval
or, in certain circumstances, prior notice, of certain material intercompany
transfers of assets as well as certain transactions between the regulated
companies, their parent holding companies and affiliates, and acquisitions.


     Under Wisconsin law, acquisition of control of us, and thereby indirect
control of our insurance subsidiaries, requires the prior approval of the OCI.
"Control" is defined as the direct or indirect power to direct or cause the
direction of the management and policies of a person. Any purchaser of 10% or
more of the voting securities of a corporation is presumed to have acquired
control of the corporation and its subsidiaries unless the OCI, upon
application, determines otherwise.

  ERISA


     The provision of goods and services to or through certain types of employee
health benefit plans is subject to ERISA. ERISA is a complex set of laws and
regulations that are subject to periodic interpretation by the federal courts
and the United States Department of Labor. ERISA places certain controls on how
our business units may do business with employers covered by ERISA, particularly
employers that maintain self-funded plans. The Department of Labor is charged
with the enforcement of ERISA and has promulgated new regulations which will
expand the claim review process. Given that the current state insurance law
governing health insurers contains stringent claim appeal process requirements,
we do not anticipate that the rules will significantly impact our operations.
There have been continued attempts to limit ERISA's preemptive effect on state
laws through proposed state and federal legislation, regulations and litigation.
If such limitations were to be imposed, they might increase our liability
exposure


                                        52


relating to employee health benefits offered by our health plans and specialty
businesses and may permit greater state regulation of other aspects of those
businesses' operations.

TRADEMARKS

     Blue Cross and Blue Shield are federally registered service marks of the
Association. Compcare(R) is a federally registered service mark of Cobalt. We
have filed for and maintain various other service marks and trade names at the
federal level and in Wisconsin. Although we consider our registered service
marks, trademarks and trade names important in the operation of our business,
our business is not dependent on any individual service mark, trademark or trade
name owned by us. CompcareBlue and BCBSUW use the Blue Cross and Blue Shield
service marks in their businesses, pursuant to a license agreement with the
Association as our controlled affiliates. Termination of this license may have a
material adverse effect on us.

                                        53

                         AGREEMENTS WITH THE FOUNDATION

CERTAIN AGREEMENTS EXECUTED IN CONNECTION WITH THE COMBINATION

     In connection with the Combination, we entered into a Voting Trust and
Divestiture Agreement and a Registration Rights Agreement, which are summarized
below.

  VOTING TRUST AND DIVESTITURE AGREEMENT

     PURPOSE

     The Association agreed to continue to grant us licenses to use the Blue
Cross and Blue Shield names and service marks following completion of the
Combination only if the Foundation agreed to deposit all of its shares of our
common stock in a voting trust and sell those shares within prescribed time
periods. The Association designed this condition to preserve our independence
from the Foundation. The Voting Trust and Divestiture Agreement summarized below
also incorporates the conditions imposed by the OCI's order approving the
conversion of BCBSUW.

     DEPOSIT OF SHARES

     The Foundation deposited into a voting trust all of the shares of our
common stock it received in the Combination. The terms of the voting trust
significantly limit the Foundation's voting rights, and the trustee of the
voting trust will vote those shares in the manner described below. In addition,
the Foundation may dispose of those shares only in a manner that would not
violate the ownership requirements contained in our Amended and Restated
Articles of Incorporation and any other agreement to which the Foundation will
be a party.

     WITHDRAWAL OF SHARES

     As described below, the Foundation must sell its shares of our common stock
within prescribed periods of time. In order to sell these shares, the Foundation
will need to withdraw shares from the voting trust from time to time. In order
to ensure that the Foundation is selling shares in a permitted manner, the
Foundation may withdraw shares from the voting trust only in order to sell such
shares and then only if:

     - we register the shares in the name of the purchaser before the Foundation
       withdraws them from the voting trust, so that the Foundation may not keep
       ownership of those shares;

     - the Foundation does not sell the shares to an affiliate of the
       Foundation, so that the Foundation may not keep indirect ownership of
       those shares;

     - the Foundation does not sell the shares to a person or entity that
       already owns shares of our common stock in excess of the ownership limits
       contained in our Amended and Restated Articles of Incorporation, so that
       the ownership limits are not violated;

     - the sale would not result in a person or entity owning shares of our
       common stock in excess of the ownership limits contained in our Amended
       and Restated Articles of Incorporation, so that the ownership limits are
       not violated; and

     - the Voting Trust and Divestiture Agreement, the Registration Rights
       Agreement and our Amended and Restated Articles of Incorporation and
       Bylaws permit the sale.

     VOTING OF SHARES HELD IN VOTING TRUST

     In general, in order to maintain our independence from the Foundation, the
trustee of the voting trust will vote the shares of our common stock owned by
the Foundation as directed by our directors, except that the Foundation will
decide how to vote these shares on a merger or similar business combination
proposal which would result in our then existing shareholders owning less than
50.1% of the resulting company, or which would result in any person or entity
who owned 50.1% or less of our common stock

                                        57


owning more than 50.1% of the voting securities of the resulting entity.
Specifically, the trustee of the voting trust will vote all of the Foundation's
shares of our common stock in the voting trust in the following manner:

     - If the matter is the election of our directors, the trustee will vote the
       shares in favor of each nominee whose nomination has been approved by (i)
       a majority of the members of our board of directors who were not
       nominated at the initiative of the Foundation or of a person or entity
       owning shares of our common stock in excess of the ownership limits
       contained in our Amended and Restated Articles of Incorporation (such
       directors being called "Independent Directors"), and (ii) a majority of
       our entire board of directors.

     - The trustee will vote against the removal of any of our directors, and
       against any change to our Amended and Restated Articles of Incorporation
       or Bylaws, unless (i) a majority of the Independent Directors, and (ii) a
       majority of our entire board of directors, initiates or consents to such
       removal or amendment action.

     - In the event that director seats are eligible for public shareholder
       representation, the trustee will be directed to vote its shares in the
       same proportion and for the same candidates voted for by the non-
       Foundation holders or our common stock. This provision will expire at
       such time as the Foundation owns less than 20% of the outstanding shares
       of our common stock.

     - The trustee will vote as directed by the board of directors of the
       Foundation on any proposed business combination transaction that if
       consummated would result in (1) the then existing holders of our common
       stock, including the Foundation, owning less than 50.1% of the
       outstanding voting securities of the resulting entity, or (2) any person
       or entity who, prior to the proposed transaction, owned less than 50.1%
       of our outstanding common stock owning 50.1% or more of the outstanding
       voting securities of the resulting entity.

     - The trustee will vote in accordance with the recommendation of our board
       of directors on any action requiring prior approval of our board of
       directors as a prerequisite to becoming effective.

     In addition, unless a majority of the Independent Directors and a majority
of our entire board of directors initiates or consents to such action, neither
the Foundation nor the trustee of the voting trust may:

     - make any change or addition to or repeal our Amended and Restated
       Articles of Incorporation or Bylaws;

     - nominate any candidate to fill any vacancy on our board of directors;

     - call any special meeting of our shareholders;

     - make any shareholder proposal pursuant to Section 2.14 of the Bylaws; or

     - take any action that would be inconsistent with the voting requirements
       contained in the Voting Trust and Divestiture Agreement.

     STANDSTILL

     As the largest holder of our common stock, the Foundation would ordinarily
enjoy the benefits of control typically held by majority shareholders. However,
in order to maintain our independence from the Foundation, as required by the
Association, the Foundation has agreed not to take actions that a shareholder of
a corporation ordinarily could take in its capacity as a shareholder.
Specifically, the Voting Trust and Divestiture Agreement provides that the
Foundation may not:

     - individually, or as part of a group, acquire the right to vote or dispose
       of any shares of our common stock or options to purchase shares of our
       stock other than those shares issued to it in the Combination, unless it
       receives the shares in a stock split or other similar transaction;

                                        58


     - enter into any agreement with any person or entity to sell shares of our
       common stock, except in accordance with the Voting Trust and Divestiture
       Agreement and the Registration Rights Agreement;

     - sell any of its shares of our common stock to a person or entity if the
       person or entity already owns, or would own as a result of the sale
       transaction and any transactions related to the sale, our common stock in
       excess of the ownership limit for the person or entity included in our
       Amended and Restated Articles of Incorporation;

     - make any shareholder proposal for submission at an annual meeting of our
       shareholders;

     - nominate any candidate to our board of directors; or

     - appoint any individual to fill a vacancy on our board of directors.

     OBSERVATION RIGHTS

     For so long as the Foundation beneficially owns at least 20% of the
outstanding shares of our common stock, the Foundation, through an authorized
representative, will have a limited right to attend and observe all meetings and
executive sessions of our board of directors. However, the authorized
representative of the Foundation will not observe any portion of a meeting
during which privileged communications between the board of directors and its
attorneys occur.

     DIVESTITURE REQUIREMENTS

     The Association requires its for-profit licensees to have limitations on
the ownership of their stock in order to maintain independence from the control
of any single shareholder or group of shareholders. The Foundation's ownership
(prior to completion of this offering) of approximately 77% of the outstanding
shares of our common stock entitled to vote would ordinarily exceed the
ownership limitations established by the Association. The Association has agreed
to waive the ownership limitations for the Foundation provided that the
Foundation satisfies a number of conditions, including selling the shares of our
common stock that it owns in the manner and within the time periods described
below.

     One-Year Divestiture Deadline

     The Foundation was required to sell shares of our common stock so that it
beneficially owned less than 80% of the outstanding common stock within one year
following completion of the Combination. Because the Foundation owned
approximately 77.5% of our outstanding shares entitled to vote immediately after
the Combination, it was not necessary for any sales to be effected during this
period.

     Three-Year Divestiture Deadline


     In addition to meeting the one-year divestiture deadline, the Foundation
must sell sufficient shares of our common stock so that it beneficially owns
less than 50% of the outstanding shares of our common stock by March 23, 2004.
Assuming the sale of 2,500,000 newly-issued shares in the current offering and
no further issuances by us, the Foundation would be required to sell
approximately 4.5 million additional shares to comply with this deadline. This
three-year period is extended day for day, up to a maximum of 365 days, for each
day that the Foundation does not require us to register the Foundation's shares
of our common stock under a demand registration because we had recently effected
a registration of our common stock. However, there shall be no such extension if
we are not required to file a registration statement pursuant to the
Registration Rights Agreement.


     Five-Year Divestiture Deadline

     In addition to meeting the one-year divestiture deadline and the three-year
divestiture deadline, the Foundation must sell sufficient shares of our common
stock so that it beneficially owns less than 20% of the outstanding shares of
our common stock by March 23, 2006. Based on the assumptions stated in the

                                        59


previous paragraph under "Three-Year Divestiture Deadline," the Foundation would
be required to sell approximately 13 million additional shares to comply with
this deadline. This five-year period is extended day for day, up to a maximum of
730 days, for each day that the Foundation does not require us to register the
Foundation's shares of our common stock under a demand registration because we
had recently effected a registration of our common stock.

     Extension of Divestiture Deadlines

     In the event that the Foundation cannot meet the divestiture deadlines, it
may be able to obtain an extension if it receives Association approval.
Specifically, we must extend the divestiture deadlines if:

     - the Foundation makes a good faith and reasonable determination that
       compliance with the divestiture deadlines would have a material adverse
       effect on the Foundation;

     - the Foundation advises us of its determination and the reasons for the
       determination and makes a reasonable request for an extension of the
       pending divestiture deadline; and

     - we received written confirmation from the Association that the
       Foundation's request for an extension of the divestiture deadline would
       not cause a violation of the license agreement between us and the
       Association.

     Similarly, we can extend the divestiture deadline for the Foundation
without a prior request by the Foundation. Any such extension is subject to
prior approval of the Association. Specifically, we may extend the divestiture
deadlines if we make a good faith determination that compliance with the
divestiture deadlines would have a material adverse effect on us or any of our
shareholders, other than the Foundation, and if we receive written confirmation
from the Association that the extension of the divestiture deadline requested by
us would not cause a violation of the license agreement between us and the
Association.

     Failure to Meet Divestiture Deadlines

     It is possible that the Foundation will not be able to meet the divestiture
deadlines. If the Foundation fails to meet a divestiture deadline, we will
arrange for the sale of those shares of our common stock that the agreement
required the Foundation to sell and will pay the proceeds received in the sale
to the Foundation, after deducting the expenses incurred by us. The sale of
these shares would likely require registration with the SEC, which may take
considerable time to complete. The Foundation will pay the expenses of the sale.
Until sold, the trustee of the voting trust will vote those shares of our common
stock as described above under "-- Voting of Shares Held in Voting Trust."

     DIVIDENDS

     We currently do not plan to declare and pay any dividends on the
outstanding shares of our common stock in the future. However, if we do declare
and pay dividends, the Foundation will be entitled to receive any such cash
dividends paid on the shares of our common stock held in the voting trust, after
the trustee deducts its fees and expenses. Any stock dividends paid on the
shares of our common stock held in the voting trust will be subject to the
voting trust as if originally deposited in the voting trust.

     TERMINATION OF VOTING TRUST AND DIVESTITURE AGREEMENT

     The Voting Trust and Divestiture Agreement will terminate once the trustee
receives notice from us and the Foundation that the Foundation beneficially owns
less than 5% of the outstanding shares of our common stock. At that point, the
restrictions and deadlines in the Voting Trust and Divestiture Agreement will no
longer apply, and the Foundation will have satisfied the divestiture deadlines.
Otherwise, the Voting Trust is irrevocable.

                                        60


     ACQUISITION PROPOSALS

     The Voting Trust and Divestiture Agreement provides that the Foundation may
not solicit or encourage inquiries or proposals with respect to, or provide any
confidential information to or have any discussions, meetings, or communications
with a person relating to, a merger, tender offer, or other business combination
involving us. However, the Foundation may:

     - have discussions with the counter-party to a business combination
       transaction after our board of directors submits the transaction to our
       shareholders for approval; and

     - have discussions with any person or entity concerning the sale of our
       common stock as permitted by the Voting Trust and Divestiture Agreement
       and the Registration Rights Agreement.

     In addition, under the Voting Trust and Divestiture Agreement, for so long
as the Foundation beneficially owns at least 20% of the outstanding shares of
our common stock, we must consult with the Foundation before soliciting, or upon
receiving, a business combination proposal in which our then existing
shareholders including the Foundation will own less than a majority of the
outstanding shares of the resulting entity.

  REGISTRATION RIGHTS AGREEMENT

     PURPOSE

     The Registration Rights Agreement gives the Foundation the right to require
us to register with the Securities and Exchange Commission the Foundation's
shares of our common stock for sale so that the Foundation may satisfy the
divestiture deadlines contained in the Voting Trust and Divestiture Agreement
without having to rely on private or other nonregistered sales. As discussed
below, the Registration Rights Agreement will also give us the option to
purchase shares of our common stock from the Foundation.

     DEMAND REGISTRATION RIGHTS

     Under federal securities laws, every offer and sale of securities must be
either registered with the Securities and Exchange Commission under the
Securities Act of 1933, as amended, or exempt from registration. The
Registration Rights Agreement gives the Foundation the right to demand that we
effect a registration with the Securities and Exchange Commission of some or all
of the shares of our common stock beneficially owned by the Foundation. The
Foundation is entitled to one demand registration per calendar year for as long
as the Foundation beneficially owns shares of our common stock, provided that we
do not have to effect a demand registration if we have effected a demand
registration within the preceding 120 days, even if that 120-day period extends
into a prior calendar year. However, our obligations to effect a demand
registration will be subject to the limitations described below.

     PURCHASE OPTION

     If the Foundation requests a demand registration, we will have the option
to purchase any or all of the shares of our common stock of which the Foundation
requests registration before we must take any action. We will not have the
option to purchase less than all of the shares if the market value of the shares
that we elect not to purchase is less than $30 million. The purchase price per
share for the shares we elect to purchase will be the average closing sale price
per share of our common stock on the New York Stock Exchange during the ten
consecutive trading days ending on the second trading day immediately preceding
the date the Foundation requests the demand registration. If we do not exercise
this option in full, we must file a registration statement for the remaining
shares, subject to the exceptions described below.

                                        61


     NO OBLIGATION TO EFFECT DEMAND REGISTRATIONS UNDER CERTAIN CIRCUMSTANCES

     If the Foundation requests a demand registration and we do not elect to
exercise our demand purchase option, we will still not be required to file a
registration statement for the shares the Foundation desires to sell if:


     - we previously registered shares of our common stock at the request of the
       Foundation at any time during the immediately preceding 120-day period;


     - we previously registered shares of our common stock at the request of the
       Foundation at any time during the calendar year in which the Foundation
       made a demand;

     - we previously effected a registration of shares of our common stock for
       sale by us during the preceding 120 days, other than shares registered
       pursuant to acquisitions or dividend reinvestment or similar employee
       plans;

     - the amount of our common stock that the Foundation seeks to register has
       a market value of less than $30 million, unless the shares are all of the
       remaining shares of our common stock the Foundation owns; or


     - we determine in good faith that a demand registration would materially
       interfere with a previously announced business combination transaction in
       which we intend to issue shares of our common stock, or would result in
       the premature disclosure of any pending development involving us, in
       which case the agreement does not require us to file a demand
       registration for a 120-day period.


     PIGGY-BACK REGISTRATION RIGHTS

     In addition to granting the Foundation the right to demand registration of
its sales of shares, the Registration Rights Agreement also permits the
Foundation to "piggy-back" on any registrations we make. Specifically, the
Registration Rights Agreement provides that whenever we propose to file a
registration statement for a public offering of shares of our common stock, the
Foundation will have the right (i) to have any or all of the shares of our
common stock that it beneficially owns included among the securities we will
register, and (ii) until it beneficially owns less than 50% of the issued and
outstanding shares of our common stock, to have any or all of its shares of our
common stock included among the securities we will register so that the
Foundation is entitled to receive up to 50% of the proceeds from the offering.

     If the lead managing underwriter for an offering for which the Foundation
requests piggy-back registration rights determines that marketing or other
factors require a limitation on the number of shares of our common stock the
parties can sell in the offering, then we will have priority over the Foundation
unless the Foundation beneficially owns more than 50% of the issued and
outstanding shares of our common stock at the time of the offering and has
elected to exercise its right, as described above, to sell shares sufficient to
receive up to 50% of the proceeds.

     CONTINUING OPTION TO PURCHASE THE FOUNDATION SHARES

     In addition to the demand purchase option described above, beginning on the
date of the earliest of

     - the consummation of a demand registration or an offering pursuant to a
       piggy-back request which results in gross sale proceeds to the Foundation
       of at least $10 million,

     - the consummation of a private placement transaction by the Foundation
       resulting in gross sale proceeds to the Foundation of at least $10
       million, or

     - the purchase by us of our common stock in a private placement resulting
       in gross sale proceeds to the Foundation of at least $10 million,

we may purchase from the Foundation any or all of the shares of our common stock
beneficially owned by the Foundation at a price equal to (i) the average closing
sale price of our common stock on the New York Stock Exchange over a 10-day
period ending on the date notice of exercise is given (or, if greater,

                                        62


the 10-day period ending on the 45th day before the date notice of exercise is
given), or (ii) the sale price received in a private placement if the Foundation
has not yet exercised its demand or piggy-back registration rights. If we
purchase shares of our common stock from the Foundation pursuant to this option,
we must hold the shares for 45 days before reselling them in a public or private
transaction.

     HOLDBACK

     It is possible that the Foundation may desire to sell its shares of our
common stock at a time when we are planning to sell additional shares for our
own benefit. In such a case, the Foundation may not sell any shares of our
common stock that it beneficially owns for a 90-day period following its receipt
of notice from us that we have filed a registration statement if the
Foundation's sale of our common stock would adversely affect our offering, or if
the lead managing underwriter, in the case of an underwritten offering, advises
us that the Foundation's sale of our common stock would adversely affect our
offering.

     Similarly, it is possible that we may desire to sell shares of our common
stock for our own benefit at a time when the Foundation desires to make a demand
registration. In such a case, we may not file a registration statement for our
common stock or securities convertible into our common stock during the 30-day
period commencing on the effective date of a registration statement filed on
behalf of the Foundation under a demand registration.

     REGISTRATION EXPENSES

     We will pay all registration expenses in connection with a demand
registration or a piggy-back registration by the Foundation except for the
Foundation's legal fees and any underwriting discounts or commissions or
transfer taxes.

     RULE 144

     The Registration Rights Agreement provides that the Foundation may not sell
any shares of our common stock that it beneficially owns pursuant to Rule 144
under the Securities Act of 1933, as amended, until the Foundation has sold at
least $50 million of our common stock to purchasers that are not affiliates of
the Foundation. Thereafter, the Foundation may sell shares of our common stock
that it owns pursuant to Rule 144 if:

     - the intended sale would not be to a person or entity that already owns
       shares of our common stock in excess of the ownership limit for that
       person or entity contained in our Amended and Restated Articles of
       Incorporation;

     - the intended sale would not cause a person or entity to own shares of our
       common stock in excess of the ownership limits for that person or entity
       contained in our Amended and Restated Articles of Incorporation; and

     - the intended sale would not otherwise violate the Registration Rights
       Agreement, the Voting Trust and Divestiture Agreement and our Amended and
       Restated Articles of Incorporation or Bylaws.

     Under Rule 144, the amount of stock that a party can sell in any
three-month period is limited, and the party can sell the stock only in
specified unsolicited broker transactions or transactions with a market maker.

     PRIVATE SALES

     If the Foundation desires to sell any or all of its shares of our common
stock in a private sale transaction to qualified investors, we will have the
right of first refusal to purchase the shares of our common stock from the
Foundation upon the same terms and conditions as the Foundation proposes to sell
the shares in the private sale.

  OTHER

     In connection with obtaining the approval of the OCI to the Combination, we
have agreed to contribute a total of $2 million cash to the Foundation. Pursuant
to an agreement with the Foundation,
                                        63


this amount must be contributed by February 1, 2003. Of this amount, $1 million
has been contributed during 2001 and 2002. The Foundation may demand any portion
of the remaining $1 million obligation at any time.

     Pursuant to a letter agreement between us and the Foundation dated June 19,
2002, the current offering constitutes a hybrid between a demand registration
and a piggyback registration under the Registration Rights Agreement.
Specifically, the registration of shares owned by the Foundation for sale in
this offering will not prevent the Foundation from demanding another
registration during 2002, subject to the Foundation's holdback requirements and
the other terms of the Registration Rights Agreement. If the lead managing
underwriters determine that marketing or other factors require a limitation on
the number of shares of our common stock the parties can sell in the current
offering, then the number of shares offered by the Foundation will be reduced,
as necessary, except that in no circumstances will the number of shares offered
by the Foundation be less than the number of shares offered by us.

                                        64


           STOCK OWNERSHIP OF MANAGEMENT AND THE SELLING SHAREHOLDER

     The following tables set forth as of March 31, 2002 information regarding
the beneficial ownership of our common stock by our directors and certain
executives, by our directors and executive officers as a group and by the
Foundation. The Foundation is the only shareholder we know to own 5% or more of
our outstanding shares of common stock. The information set forth below has been
furnished to us by the respective named shareholders.


     Beneficial ownership is determined in accordance with Securities and
Exchange Commission rules. In general, these rules attribute beneficial
ownership of securities to persons who possess sole or shared voting power
and/or investment power with respect to those securities and includes, among
other things, securities that an individual has the right to acquire within 60
days. Unless otherwise indicated, the shareholders identified in the following
tables have sole voting and investment power with respect to all shares shown as
beneficially owned by them. Percentage ownership calculations for any individual
listed below are based on 40,666,385 shares of our common stock outstanding as
of March 31, 2002 plus all shares of our common stock which the individual may
acquire beneficial ownership of pursuant to stock options that are exercisable
or that will become exercisable within 60 days before this offering, and
43,166,385 shares of our common stock outstanding after this offering, based on
the number of shares outstanding as of March 31, 2002.

     In addition, the Foundation has granted to the underwriters an option to
purchase up to 1,125,000 additional shares of common stock to cover
over-allotments, if any, incurred in connection with this offering. If the
option is exercised in full, then the Foundation will own 25,188,390 shares, or
approximately 57.8%, of our outstanding common stock. See "Background of the
Company" and "Agreements With the Foundation" for a description of other
material transactions between us and the Foundation.


                                        66


                      ARTICLES OF INCORPORATION AND BYLAWS

     Our Amended and Restated Articles of Incorporation ("Articles") and our
Amended and Restated Bylaws ("Bylaws") contain certain provisions regarding the
required composition of our board of directors and ownership of our common stock
that investors should understand when considering an investment in our common
stock. We have set forth below a short summary of some of those provisions, and
a short description of how completion of the offering will affect the board
composition requirements. In the following summary, the term "person" includes
any individual or entity.

QUALIFICATION OF DIRECTORS

  GENERAL

     Our board of directors is currently comprised of nine members, which is the
maximum number of board positions authorized by our Articles and our Bylaws. The
current directors, taken as a group and each individually, satisfy specific
board composition and individual criteria imposed by the Association and OCI as
a result of the Combination. Certain of these standards are based solely upon
the amount of issued and outstanding common stock beneficially owned by the
Foundation, and will terminate when the Foundation's holdings decrease below
20%. Due to this correlation to the Foundation's holdings of our common stock,
an increase in outstanding shares, sales of shares by the Foundation, or a
combination of both could potentially affect the required composition of our
board of directors.

  INDEPENDENT DIRECTORS

     Our Articles provide that no one will be able to become one of our
directors unless (i) he or she is an "Independent Director" (as defined below),
or (ii) immediately after he or she becomes a director, at least a specified
percentage of our directors would be Independent Directors. Currently, at least
78.75% of our directors are required to qualify as Independent Directors. This
means that there can be a maximum of one non-Independent Director as of the date
of this prospectus. The percentage of directors that must be Independent
Directors will decrease as the Foundation's stock ownership decreases, according
to a formula described below. A person will qualify as an "Independent Director"
if he or she:

     - is not a "major participant" (as defined below);

     - has not been nominated to be a director at the initiative of a major
       participant;

     - has not announced a commitment to a proposal made by a major participant
       that has not been approved by an "independent board majority" (as defined
       below); and

     - has not been determined by an independent board majority to have been
       subject to any relationship or arrangement which those directors deem to
       be likely to interfere with his or her exercise of independent judgment.

     As used above, an "independent board majority" means a group of directors
consisting of a majority of all Independent Directors AND a majority of all
directors. A "major participant" means:

     - the Foundation, or any other person, in the judgment of an independent
       board majority, that succeeds to the Foundation's position;

     - a person that owns shares of our common stock in excess of the ownership
       limitations described below;

     - a person that has filed proxy materials with the Securities and Exchange
       Commission supporting a candidate for election to the board of directors
       in opposition to candidates approved by an independent board majority;

     - a person that has taken actions deemed by an independent board majority
       to indicate that such person will seek to become a major participant; or

     - a person that is an affiliate or associate of a major participant.

                                        67


     If, however, an independent board majority has given prior approval to an
acquisition of our common stock by a person and that acquisition would otherwise
have caused that person to become a major participant, the acquiring person will
nevertheless not be a major participant so long as the person (i) makes no
subsequent acquisition of our common stock not approved by an independent board
majority, and (ii) takes no other action that would make that person a major
participant, without the prior approval of an independent board majority. The
Foundation will always be a major participant.

     The board of directors composition specified by our Articles will change as
the Foundation's ownership of our common stock decreases. For each 1% reduction
in the percentage of our outstanding common stock owned by the Foundation below
80%, the percentage of board seats that must be occupied by Independent
Directors will be reduced by one-half of 1%. For example, when the Foundation's
holdings have been reduced to 50% of our outstanding common stock, the Amended
and Restated Articles of Incorporation will require that at least 65% of the
directors be Independent Directors. However, the Independent Directors will
always be required to comprise a majority of the board.

  INDEPENDENT PUBLIC SHAREHOLDER REPRESENTATION

     As part of the Combination, OCI imposed certain board composition
requirements in an effort to reflect "independent public shareholder
representation," which relates to the number of shares owned by the investing
public apart from the Foundation. For those positions on our board of directors
which are not required to satisfy the definition of Independent Director, an
individual nominated and elected to such a position must satisfy different
"independent public shareholder representative" criteria set forth in our
Bylaws. Based upon the current independent board majority percentage, only one
board position must satisfy OCI's "independent public shareholder
representative" criteria. Three current board members, Messrs. Richard Abdoo,
Barry Allen, and Dr. William Rupp, each satisfy this test.

  IMPACT OF THE OFFERING


     If this offering is completed, then the sale of newly issued shares by us
and the sale of 6,125,000 shares beneficially owned by the Foundation (assuming
exercise of the underwriters' overallotment option in full) would decrease by
one the board positions which must satisfy the definition of Independent
Director, and result in two positions which would need to satisfy OCI's
"independent public shareholder representative" criteria. Following the sale of
6,125,000 shares, the Foundation would beneficially own 25,188,390 shares of our
common stock. Given the increase in issued and outstanding shares following this
offering, the Foundation's holdings would then comprise approximately 57.8% of
our issued and outstanding shares. The independent board majority requirement
would then be 68.9% due to its proportional decrease related to the Foundation's
holdings. In the context of a nine member board, at least seven positions then
must satisfy the definition of Independent Director, and as a result two
positions would need to satisfy OCI's "independent public shareholder
representative" criteria. When the independent board majority percentage reaches
66.67%, then only six positions must satisfy the Independent Director
requirement, and at that point three positions would need to satisfy OCI's
"independent public shareholder representative" criteria.


     As illustrated above, the completion of this offering will affect the board
composition requirements imposed by the Association and OCI. However, the impact
on the board composition requirements will not practically affect any individual
membership on the current board (assuming Messrs. Richard Abdoo, Barry Allen,
and Dr. William Rupp continue to serve as directors following the offering),
since all resulting board requirements will continue to be satisfied. This is
because each member of the current board satisfies the Independent Director
requirements, and Messrs. Richard Abdoo, Barry Allen, and Dr. William Rupp
currently satisfy OCI's "independent public shareholder representative"
criteria.

QUALIFIED CANDIDATES

     Our Amended and Restated Bylaws provide that shareholders will elect
directors by a plurality vote and that shareholders may only elect "qualified
candidates" to the board of directors. A qualified candidate

                                        68


is an individual nominated by an independent board majority or properly
nominated pursuant to the procedures set forth in our Amended and Restated
Bylaws, and, in either event, who is not disqualified by virtue of being a
"non-independent candidate" for whom there is no board seat available because of
the requirement that at least a specified percentage (between 50.01% and 80%) of
the directors be Independent Directors. A "non-independent candidate" is a
candidate who would not qualify as an "Independent Director," as described
above.

     If there are more qualified candidates in any election of directors than
available board seats, then the independent candidates receiving the greatest
number of votes will win the seats reserved for Independent Directors, and the
remaining candidate(s) who satisfy certain eligibility requirements imposed
under Section 3.04 of our Amended and Restated Bylaws (whether independent or
non-independent candidates) receiving the greatest number of votes will win any
seat(s) available for non-Independent Directors. (However, under the terms of
the voting trust and divestiture agreement with the Foundation, the trustee of
the voting trust is required, in an election involving board seats not reserved
for Independent Directors, to vote the Foundation's shares in proportion to the
votes cast by shareholders other than the Foundation. See "Agreements With the
Foundation -- Voting Trust and Divestiture Agreement -- Voting of Shares Held in
Voting Trust.")

LIMITATIONS ON COMMON STOCK OWNERSHIP

  GENERAL

     Our Articles contain the following ownership limitations required by the
Association for its for-profit licensees. These limitations are imposed to
protect the licensee's independence from any single shareholder or concerted
group of shareholders. Under these ownership limitations:

     - no institutional owner may beneficially own 10% or more of the combined
       voting power of all of our outstanding securities;

     - no non-institutional owner may beneficially own 5% or more of the
       combined voting power of all of our outstanding securities; and

     - no person may own 20% or more of all of our outstanding equity securities
       (regardless of voting power).

     Our Articles define "beneficial ownership" to include securities:

     - in which a person has a direct or indirect ownership interest;

     - which a person has a right or option to purchase;

     - which a person has the right to vote;

     - with respect to which a person would be required to file a Schedule 13D
       or 13G under the Securities Exchange Act of 1934, as amended; or

     - which are owned by any affiliate or associate of the person, or by anyone
       else with which the person has any agreement or understanding.

     Our Articles also include a number of exceptions to the definition of
beneficial ownership (for example, a pledgee of stock or one in possession of a
revocable proxy is not a beneficial owner).

  VIOLATION OF LIMITATION ON OWNERSHIP

     Except as set forth below, if any person beneficially owns our securities
in excess of the ownership limits, then (i) the person will not receive any
rights to the excess shares, and (ii) the excess shares will immediately be
deemed to be transferred to a "share escrow agent" appointed by us to sell the
excess shares. However, a person's beneficial ownership will not violate the
ownership limits if the person's excess shares do not exceed the lesser of 1% of
the voting power of the capital stock or 1% of the ownership

                                        69


interest of us, and the person disposes of the excess shares within fifteen days
of becoming aware of the ownership of excess shares.

  EXCEPTIONS TO OWNERSHIP LIMITS

     The ownership limits described above do not apply to shares received by the
Foundation in the Combination, or any shares acquired by the Foundation as a
result of a subsequent stock dividend, stock split, conversion or similar
distribution. However, the ownership limits will apply to shares transferred by
the Foundation or the voting trust to any other person.

  CHANGE IN OWNERSHIP LIMITS

     In addition, an independent board majority together with the holders of 75%
or more of the outstanding shares of our common stock may change the ownership
limits, without regard to the terms of the license agreement, by amending the
Articles as described below.

CONTROL SHARE VOTING RESTRICTIONS

     Our Articles provide that shares of our common stock owned by the
Foundation or the trustee are not subject to the voting power restrictions
provided by Section 180.1150(2) of Wisconsin law, which would otherwise limit
the voting power of our shares owned by the Foundation and the trustee that
exceed 20% of the voting power in the election of directors to 10% of the full
voting power of such excess shares.

AMENDMENTS TO AMENDED AND RESTATED ARTICLES OF INCORPORATION

     Our Articles provide that the approval of an independent board majority and
of the holders of 75% or more of the outstanding shares of common stock will be
required in order to amend various sections of the Articles, including the
sections dealing with:

     - the number, qualifications, limitations on liability and removal of
       directors;

     - the inability of shareholders to act by written consent;

     - special shareholder meetings;

     - the ownership limitations;

     - amendments to the Bylaws;

     - the prohibition on cumulative voting; and

     - the right to amend the Articles.

     The supermajority votes described above will not be necessary if any of the
following applies:

     - we no longer have any license agreements with the Association;

     - the amendment in question is an amendment to the ownership limitation and
       transfer restriction provisions of the Articles which has been proposed
       in order to conform to a change in the terms of any Association license
       agreement;

     - the amendment in question is any other amendment to the ownership
       limitation and transfer restriction provisions that is required or
       permitted by the Association, whether or not it constitutes a change to
       any license agreement; or

     - the amendment in question is an amendment to the ownership limitation and
       transfer restriction provisions which has been approved by an independent
       board majority in connection with a proposal to acquire all our
       outstanding capital stock.

For so long as the Foundation owns at least 20% of the outstanding shares of our
common stock, any amendment of the Articles will be subject to the prior review
and approval of the OCI.

                                  UNDERWRITING

     UBS Warburg LLC and Salomon Smith Barney Inc. are acting as joint
book-running managers and, together with CIBC World Markets Corp. and Robert W.
Baird & Co. Incorporated, are acting as representatives of the underwriters
named below. We, the Foundation and the underwriters have entered into an
underwriting agreement concerning the shares being offered. Subject to certain
conditions, each underwriter has severally agreed to purchase the number of
shares indicated in the following table.

<Table>

</Table>


     If the underwriters sell more shares than the total number set forth in the
table above, then the underwriters have a 30-day option to buy up to an
additional 1,125,000 shares from the Foundation, at the public offering price
less the underwriting discounts and commissions, to cover these sales. If any
shares are purchased under this option, then the underwriters will severally
purchase shares in approximately the same proportion as set forth in the table
above.



     The following table provides information regarding the amount of the
underwriting discounts and commissions to be paid by us and the Foundation.
These amounts are shown assuming both no exercise and full exercise of the
underwriters' option to purchase up to 1,125,000 additional shares.

</Table>

     We estimate that the total expenses of this offering payable by us,
excluding underwriting discounts and commissions, will be approximately
$750,000.

     Shares sold by the underwriters to the public will initially be offered at
the public offering price set forth on the cover of this prospectus. Any shares
sold by the underwriters to securities dealers may be sold at a discount of up
to $     per share from the public offering price. Any of these securities
dealers may resell any shares purchased from the underwriters to other brokers
or dealers at a discount of up to $
per share from the public offering price. If all the shares are not sold at the
public offering price, the representatives may change the offering price and the
other selling terms.


     We have agreed with the underwriters not to offer, sell, contract to sell,
hedge or otherwise dispose of, directly or indirectly, any of our common stock
or securities convertible into or exchangeable for shares of common stock during
the period from the date of this prospectus continuing through and including the
date 90 days after the date of this prospectus, without the prior written
consent of UBS Warburg LLC. Each of our executive officers, our directors and
the Foundation have also agreed to these restrictions.


     In connection with this offering, Salomon Smith Barney, on behalf of the
underwriters, may purchase and sell shares of our common stock in the open
market. These transactions may include stabilizing transactions, short sales and
purchases to cover positions created by short sales. Stabilizing transactions
consist of bids or purchases made for the purpose of preventing or retarding a
decline in the market price of our common stock while this offering is in
progress. These transactions may also include short sales and purchases to cover
positions created by short sales. Short sales involve the sale by the
underwriters of a greater number of shares than they are required to purchase in
this offering. Short sales may be either

                                        71


"covered short sales" or "naked short sales." Covered short sales are sales made
in an amount not greater than the underwriters' over-allotment option to
purchase additional shares in this offering. The underwriters may close out any
covered short position by either exercising their over-allotment option or
purchasing shares in the open market. In determining the source of shares to
close out the covered short position, the underwriters will consider, among
other things, the price of shares available for purchase in the open market as
compared to the price at which they may purchase shares through the
over-allotment option. Naked short sales are sales in excess of the
over-allotment option. The underwriters must close out any naked short position
by purchasing shares in the open market. A naked short position is more likely
to be created if the underwriters are concerned there may be downward pressure
on the price of shares in the open market after pricing that could adversely
affect investors who purchase our common stock in this offering.

     The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because Salomon Smith Barney, on behalf of the
underwriters, has repurchased shares sold by or for the account of that
underwriter in stabilizing or short covering transactions.

     These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of our common stock. As a result, the price of our
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the New York
Stock Exchange or otherwise.

     We and the Foundation have agreed to indemnify the several underwriters
against some liabilities, including liabilities under the Securities Act of
1933, and to contribute to payments that the underwriters may be required to
make in respect thereof.


     Robert W. Baird & Co. Incorporated, one of the underwriters in this
offering, has been retained by the Foundation to provide financial advisory
services and will be entitled, upon completion of this offering, to a customary
fee as well as reimbursement of expenses.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors
Cobalt Corporation

     We have audited the accompanying consolidated balance sheets of Cobalt
Corporation (the "Company") as of December 31, 2001 and 2000, and the related
consolidated statements of operations, changes in shareholders' equity and
comprehensive income (loss) and cash flows for each of the three years in the
period ended December 31, 2001. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audits to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of the Company at
December 31, 2001 and 2000, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
2001, in conformity with accounting principles generally accepted in the United
States.

                               COBALT CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  ORGANIZATION, ACCOUNTING FOR CONVERSION AND COMBINATION, AND BASIS OF
PRESENTATION

     Cobalt Corporation ("Cobalt" or the "Company") (formerly known as United
Wisconsin Services, Inc. ("UWS")) was created as a result of the Combination of
UWS and Blue Cross & Blue Shield United of Wisconsin ("BCBSUW") on March 23,
2001 (the "Combination"). On that date, BCBSUW converted from a service
insurance corporation to a shareholder owned corporation. Upon conversion,
BCBSUW became a wholly-owned subsidiary of UWS through a combination of the two
companies. At the time of the conversion and combination, BCBSUW owned
approximately 46.6% of UWS' outstanding common stock. In exchange for the
ownership of BCBSUW, Cobalt issued 31,313,390 shares of newly issued Company
common stock to the Wisconsin United for Health Foundation, Inc. (the
"Foundation"). The Foundation was established for the sole purpose of benefiting
public health in Wisconsin from its earnings in the investment in Cobalt.

     The Combination was accounted for as a purchase by BCBSUW of the remaining
9,096,303 shares of UWS that it did not already own at a market price of $6.15
per share on the closing date. In accordance with accounting principles
generally accepted in the United States ("GAAP"), goodwill was recorded
representing the excess of the market price over the adjusted book value of UWS
for the 53.4% of UWS that BCBSUW did not already own. Total goodwill recorded by
Cobalt as a result of the Combination amounted to $65,577,000, of which
$21,651,000 related to the recognition of a valuation allowance on the net
deferred income tax assets recorded by UWS prior to the Combination.


     For financial reporting purposes, the Combination is treated as a reverse
purchase transaction, whereby BCBSUW becomes the acquirer and reporting entity
for public company reporting. Therefore, the accompanying audited consolidated
financial statements present the Company's financial position as of December 31,
2001, reflecting the purchase accounting adjustments for the Combination and
include the accounts of both UWS and BCBSUW. The financial position of the
Company presented in the December 31, 2000 balance sheet represents only the
accounts of BCBSUW, which includes BCBSUW's 46.6% investment in UWS and 44%
investment in American Medical Security Group, Inc. ("AMSG") (see Note 6). The
consolidated statements of operations, cash flows, and changes in stockholders'
equity and comprehensive income (loss) for the year ended December 31, 2001,
reflect the operations of the combined UWS and BCBSUW entities effective March
31, 2001 with AMSG continuing to be accounted for using the equity method. Prior
to March 31, 2001, the consolidated financial statements include the operations
of BCBSUW, its wholly-owned subsidiary, United Government Services, LLC ("UGS")
and BCBSUW's investment in UWS and AMSG. For purposes of calculating earnings
per common share ("EPS") of the Company, the 7,949,904 shares of Cobalt common
stock owned by BCBSUW is accounted for as if it were treasury stock.


     The consolidated financial statements subsequent to the Combination include
the accounts of the Company's majority owned insurance subsidiaries (BCBSUW,
Compcare Health Services Insurance Corporation ("Compcare"), Unity Health Plans
Insurance Corporation ("Unity"), Valley Health Plan, Inc. ("Valley"), United
Wisconsin Insurance Company ("UWIC"), and United Heartland Life Insurance
Company ("UHLIC")) and other non-insurance subsidiaries (UGS, Meridian Resource
Company, LLC ("MRC"), Comprehensive Receivables Group, Inc. ("CRG"), United
Wisconsin Proservices, Inc. ("Proservices"), United Heartland, Inc. ("UHI") and
C.C. Holdings, LLC ("CC Holdings")) as continuing operations. All intracompany
balances as of March 31, 2001 and transactions after March 31, 2001 have been
eliminated in consolidation.

  MARCH 31, 2002 UPDATE (UNAUDITED)


     Discontinued operations includes the operations of Innovative Resource
Group, LLC ("IRG"), which is a behavioral health subsidiary of the Company that
was sold on March 29, 2002 (see Note 19).


                                       F-7

                               COBALT CORPORATION

2.  MANAGEMENT'S PLAN

     During the three years in the period ended December 31, 2001, the Company
incurred operating losses from continuing operations aggregating $55.4 million.
Included in these losses are $27.8 million related to the Company's
participation in the Medicare+Choice line of business, which the Company exited
effective January 1, 2002. Prior to the Combination, UWS and its subsidiaries
incurred additional operating losses from continuing operations aggregating
$77.8 million for the first quarter of 2001 and the two years ended December 31,
2000. These losses largely relate to the HMO business in southeast Wisconsin.
Significant actions were taken during 2001 to cancel unprofitable HMO business.
Also contributing to the combined aggregate losses were $8.7 million of expenses
relating to the Combination. On a pro forma basis, Cobalt's operating loss from
continuing operations for 2001 was $1.4 million (see Note 1). Despite these
recent operating losses and the implementation of changes in statutory
accounting ("Codification") effective January 1, 2001, the Company complied with
minimum capital and liquidity requirements of the Office of the Commissioner of
Insurance of the State of Wisconsin ("OCI") and the BlueCross BlueShield
Association ("BCA"), during 2001, 2000 and 1999. The Company maintained
compliance, in part, by contributing regulated and non-regulated subsidiaries to
regulated entities and by collateralizing certain intra-company debt obligations
with the common stock of affiliated entities. OCI requested and management
submitted a specific plan of action to continue to exceed the minimum capital
requirements of the OCI and the BCA during 2002 (see Note 15).

     The outstanding common stock of Compcare, Unity, Valley and UHI currently
provide the collateral for approximately $92 million borrowed by Cobalt from
BCBSUW and UWIC. These intra-company balances have been eliminated in the
accompanying December 31, 2001 consolidated balance sheet. However, the
intra-company balances continue to be an obligation of Cobalt to BCBSUW ($70
million) and UWIC ($22.6 million) in the statutory-basis financial statements of
BCBSUW and UWIC. Cobalt is obligated to repay BCBSUW by January 2, 2003 and UWIC
by October 1, 2002. Transfer of the pledged collateral to BCBSUW and UWIC will
satisfy the legal obligations, but would not assist BCBSUW in complying with
minimum capital and liquidity requirements, since the minimum capital
calculations for investments in subsidiaries require a greater discount than for
cash, marketable securities or affiliated receivables. However, settlement of
these obligations in cash will assist compliance with minimum capital and
liquidity requirements.

     At December 31, 2001, all of the Company's subsidiaries are accounted for
in the BCBSUW or Compcare capital calculations as a result of contribution or
collateralization.

     In order to assure the Company's regulated insurance subsidiaries continue
to satisfy minimum capital and liquidity requirements, the OCI requested,
management developed and the Cobalt board of directors approved a capital plan
to improve the Company's position relative to minimum capital and liquidity

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

requirements. The capital plan, which management has provided to and discussed
with the OCI and BCA, includes the following action steps to maintain required
capital and liquidity levels during 2002:

     - Sell certain non-regulated subsidiaries owned by the Company for cash
       and/or notes prior to October 1, 2002.

     - Reduce BCBSUW's investment in AMSG common stock from 45% of the shares
       outstanding to less than 20% through public or private offerings during
       2002.

     - Obtain debt financing at the Company's corporate holding company from one
       or more institutional lenders to fund holding company liquidity needs
       including the repayment of the collateralized intra-company debt
       obligations between the holding company and its regulated subsidiaries.

     - Achieve the Company's 2002 projected core earnings, which anticipate
       breakeven operating results for Compcare for the year ending December 31,
       2002 as compared to an operating loss of $32.5 million for the year ended
       December 31, 2001. Management expects Compcare's significant change in
       profitability to occur as a result of efforts in the fourth quarter of
       2001 to cancel unprofitable business and implement necessary premium
       increases for the remaining business.

     - Adhere to certain practices in conducting and accounting for affiliated
       transactions, notably involving the lending practices previously
       described. The Company will not use uncollateralized non-operating
       intra-company balances in complying with minimum capital and liquidity
       requirements. The Company has reflected the revised practices in the
       December 31, 2001 regulated subsidiary statutory-basis financial
       statements filed with the OCI and other regulatory agencies.

     - Satisfy the $70 million debt obligation to BCBSUW by December 31, 2002,
       either with cash obtained through external financing or by transferring
       the stock of Compcare to BCBSUW or a combination thereof.

     - Satisfy the $22.6 million debt obligation to UWIC by September 30, 2002,
       either with cash obtained through external financing or by transferring
       the stock of Unity, Valley and UHI to UWIC.

  MARCH 31, 2002 UPDATE (UNAUDITED)

     During the first quarter of 2002, the Company completed the following
elements of its capital plan:

     - Sold 100% of the membership interest of its subsidiary, IRG (see Note 19,
       Discontinued Operations).


     - Reduced its ownership in AMSG from 45% to 39% through the sale of 1.4
       million shares of AMSG common stock (see Note 6, Investment in
       Affiliates).


     - Achieved the Company's first quarter 2002 projected core earnings,
       including progress towards obtaining breakeven results for Compcare by
       the end of the year.

     The Company expects to remain in compliance with minimum capital and
liquidity requirements of the OCI and the BCA throughout 2002 by substantially
completing the capital plan described above or transactions with an equivalent
impact on the Company's position relative to minimum capital and liquidity
requirements. Non-compliance with minimum capital and liquidity requirements may
subject the Company to various regulatory actions by the OCI and BCA, including
rehabilitation, revocation of the Company's license to sell insurance products
in Wisconsin and revocation of the Company's license to operate as a Blue
Cross/Blue Shield franchisee.

3.  SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

     The Company actively manages its cash and cash equivalents position to
maintain optimal asset levels. Cash and cash equivalents include operating cash
and short-term investments with original maturities of three months or less.
These amounts are recorded at cost, which approximates fair value.

INVESTMENTS

     Investments are classified as either held-to-maturity or
available-for-sale. Investments that the Company has the intent and ability to
hold to maturity are designated as held-to-maturity and are stated at amortized
cost. All other investments are classified as available-for-sale and are stated
at estimated fair value based on quoted market prices. The net unrealized gain
or loss on investment securities classified as available-for-sale, net of
deferred income taxes, is included in accumulated other comprehensive income
(loss) in shareholders' equity. Realized gains and losses from the sale of
available-for-sale debt and equity securities are calculated using the first-in,
first-out basis.

     Investments in affiliates in which the Company does not have control, but
has the ability to exercise significant influence over operating and financial
policies are accounted for by the equity method. The Company's investments in
AMSG common stock and pre-combination UWS common stock (see Note 6) are
accounted for on the equity method.

     Investments in debt and equity securities, as well as investment in
affiliates, are reviewed periodically by Company management to determine whether
there is any impairment in the historical cost of the investment deemed other
than temporary. Any impairments deemed other than temporary are recorded as a
reduction of the historical cost of the respective investment and as a realized
loss in the Company's consolidated statement of operations. Effective December
31, 2001, the Company recorded a reduction in the carrying value of its
investment in AMSG (see Note 6).

PREMIUM RECEIVABLES

     Premium receivables are stated at net realizable value, net of allowances
for uncollectible amounts of $2,371,000 and $227,000 at December 31, 2001 and
2000, respectively, based upon historical collection trends and management's
best estimate of the ultimate collectibility.

DUE FROM CLINICS AND PROVIDERS

     Amounts due from clinics and providers are stated at net realizable value,
net of allowances for uncollectible amounts of $9,124,000 and $846,000 at
December 31, 2001 and 2000, respectively, based upon management's best estimate
of the ultimate collectibility.

OTHER RECEIVABLES

     Other receivables are stated at net realizable value, net of allowances for
uncollectible amounts of $3,715,000 and $4,061,000 at December 31, 2001 and
2000, respectively, based upon management's best estimate of the ultimate
collectibility.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over the estimated
useful lives of the related assets, which is 3 years for computer equipment and
software, 5 to 10 years for furniture and other equipment, 30 years for land
improvements and 10 to 40 years for buildings and building improvements. Any
gain or loss realized upon

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

retirement or disposal is reflected in selling, general, administrative and
other expenses in the Company's consolidated statement of operations. On an
on-going basis, the Company reviews events or changes in circumstances that may
indicate that the carrying value of an asset may not be recoverable.

GOODWILL

     Goodwill represents the excess of the market value over the adjusted book
value for the additional UWS shares purchased by BCBSUW on March 23, 2001 (see
Note 1), along with the excess of cost over the fair value of other businesses
acquired. Goodwill was amortized on a straight-line basis over a weighted
average period of approximately 16 years. Amortization of goodwill was
$5,136,000, $622,000 and $191,000 for the years ended December 31, 2001, 2000
and 1999, respectively. Accumulated amortization was $7,455,000 and $813,000 at
December 31, 2001 and 2000, respectively.

     The Company reviews goodwill for impairment annually or sooner if events or
changes in circumstances occur, which may affect the estimated useful life or
the recoverability of the remaining balance of goodwill. At December 31, 2001,
the Company's management believed that no material impairment of goodwill
existed.

DEFERRED ACQUISITION COSTS

     Certain costs of acquiring new insurance policies for workers' compensation
and certain individual health products have been deferred. Deferred acquisition
costs of $9,488,000 and $6,930,000 at December 31, 2001 and 2000, respectively,
are included in other noncurrent assets and are being amortized over the
estimated premium-paying periods of the related policies. Acquisition costs of
$4,467,000, $2,661,000 and $2,946,000 were capitalized in 2001, 2000 and 1999,
respectively. Deferred acquisition costs of $3,384,000, $2,289,000 and
$2,092,000 were amortized during 2001, 2000 and 1999, respectively.

     In addition to the amortization above during 2000, the Company wrote-off
$2,434,000 of deferred acquisition costs associated with the Medicare+Choice
line-of-business.

MEDICAL AND OTHER BENEFITS

     The Company contracts with various health care providers for the provision
of certain medical care services to its members and generally compensates those
providers on a fee-for-service basis or pursuant to certain risk-sharing
arrangements. Medical and other benefits expense also consists of capitation
expenses, health and disability benefit claims and life insurance benefits. In
addition to actual benefits paid, medical and other benefits expense includes
the change in estimates of reported and unreported claims and accrued capitation
fees and adjustments, which are unpaid as of the balance sheet date. The
estimates of reported and unreported claims and accrued capitation fees and
adjustments, which are unpaid as of the balance sheet date, are based on
historical payment patterns using standard actuarial techniques. Processing
costs are accrued as operating expenses based on an estimate of the costs
necessary to process these claims.

     The Company's year-end claim liabilities are substantially satisfied
through claim payments in the subsequent year. Any adjustments to prior period
estimates are reflected in the current period. Capitation represents fixed
payments on a per member per month basis to participating physicians, dentists,
other medical specialists and hospital systems as compensation for providing
comprehensive health or dental care services. In addition, certain subsidiaries
have risk-sharing, stop-loss, and bonus arrangements with certain providers.
Estimated settlements relating to these arrangements are developed based on
historical payment patterns using standard actuarial techniques. The portion of
medical and other benefits payable pertaining to long-term disability, workers'
compensation and certain life insurance products, which is estimated to be paid
more than one year from the balance sheet date, is included as other benefits
payable on the accompanying consolidated balance sheets.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

PREMIUM DEFICIENCY RESERVES

     Premium deficiency reserves ("PDR") are recognized when it is probable that
the future costs associated with a group of existing contracts will exceed the
anticipated future premiums on those contracts. For purposes of determining
whether a premium deficiency exists, contracts are grouped in a manner
consistent with the Company's method of acquiring, servicing and measuring
profitability of such contracts. The Company calculates expected PDR based on
budgeted revenues and applicable expenses excluding investment income.

     As a result of management's assessment of the profitability of its
Medicare+Choice line of business, during the third quarter of 2000 the Company
recorded a provision for probable future losses (premium deficiency). At
December 31, 2000, $3,617,000 is included in medical and other benefits payable
as a PDR for this line of business. As of December 31, 2001, there was no PDR
needed as a result of the Company exiting this business effective January 1,
2002. The provision for probable future losses is calculated based on a
comparison of anticipated premiums to health care related costs, including
estimated payments for providers, commissions and the cost of collecting
premiums and processing claims. Inadequate compensation from the Centers for
Medicare and Medicaid Services and increased medical benefits contributed to the
requirement for a provision for future losses.

POSTRETIREMENT/POSTEMPLOYMENT BENEFITS

     Pension costs are accrued and are funded based on the minimum contribution
requirements of the Employee Retirement Income Security Act of 1974. The
actuarial cost method used is the projected unit credit method. The Company also
provides certain health and life insurance benefits to retired employees.

     The Company accrues disability related postemployment benefits when it
becomes probable that such benefits will be paid and when sufficient information
exists to make reasonable estimates of the amounts to be paid.

REVENUE RECOGNITION

     Health services premiums are recognized as revenue in the period in which
enrollees are entitled to care. Managed care consulting revenues are generally
recognized when services are rendered. Case management revenues are recognized
when services are billed. Receivables management revenues are recognized when
cash is received.

     As a fiscal intermediary for Medicare, the Company is reimbursed for
administrative costs incurred in providing this service. In addition, the
Company also administers various uninsured programs sponsored by the federal and
state government (including State of Wisconsin Medicaid as a subcontractor) and
private corporations, for which the Company receives administrative fees. These
revenues are recognized as the services are performed.

     Retrospective premium adjustments are recognized for certain groups for
which actual claims experience differs from that which was anticipated when the
related premium rates were established. Financial arrangements vary based upon
the group and line of insurance involved. The amount of premium that was subject
to retrospective premium adjustments in 2001, 2000 and 1999, was $14,365,000,
$16,441,000 and $35,179,000, respectively.

INCOME TAXES

     Deferred tax assets and liabilities are recognized for the estimated future
tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and tax credit carryforwards. Deferred tax assets and liabilities are
measured using tax rates expected to apply to taxable income in the years in
which those temporary differences are

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date. A valuation allowance is recorded on deferred tax
assets when management determines that it would be "more likely than not" that
the tax benefit of the federal and state net operating loss ("NOL") carryovers
would not be realized prior to their expiration.

SELF-FUNDED BUSINESS

     Administrative expenses include costs associated with maintenance of
membership records, claim processing and payment, coordination of benefits,
billing/cash collection and other services on self-funded business. The Company
is reimbursed for claims paid and a fee is received for the administrative costs
associated with providing these services. Benefits paid on self-funded programs
were $561,194,000, $522,566,000 and $527,987,000 in 2001, 2000 and 1999,
respectively, are excluded from the accompanying statements of operations.
Administrative fees received related to these programs totaled $28,067,000,
$24,716,000 and $25,970,000 in 2001, 2000 and 1999, respectively, and are
included in other revenue in the accompanying consolidated statements of
operations.

     Basic EPS excludes dilution and is computed by dividing income available to
common shareholders by the weighted average number of common shares outstanding
during the period. Diluted EPS reflects the potential dilution that could occur
if all stock options were exercised and converted into common stock. When the
Company reports a net loss, stock options are not included in the calculation of
EPS because their inclusion would have an antidilutive effect. EPS for the year
ended December 31, 2001 was calculated based on 38,434,459 weighted average
shares outstanding, which assumes that the 31,313,390 of newly issued shares to
the Foundation were outstanding for the entire three months ended March 31,
2001. EPS was not presented for the years ended December 31, 2000 and 1999
because the Company was a service insurance corporation.

USE OF ESTIMATES

     The accompanying consolidated financial statements have been prepared in
accordance with GAAP, which requires management to make estimates and
assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates. Operating results for the three months ended March 31, 2002 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2002.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 2001, the Financial Accounting Standards Board ("FASB") approved
the issuance of FASB statement #142, "Goodwill and Other Intangibles". Under
this statement, the Company must review the goodwill recorded on its balance
sheet and the impact of the statement on the carrying value of its investment in
AMSG for impairment based on a two-step process described in the statement. The
first step is a screen for potential impairment, while the second step measures
the amount of impairment, if any, based on fair value. In addition, the
statement requires the discontinuance of goodwill amortization upon adoption
(January 1, 2002). Although management believes that based on its review of the
impact of adopting this standard, no significant impairment charge is expected
related to goodwill recorded on its balance sheet or the carrying value of its
investment in AMSG, this analysis has not yet been completed. In addition,
discontinuance of goodwill amortization, excluding its investment in AMSG, is
estimated to reduce expense on the Company's consolidated statement of
operations by approximately $7.6 million annually.

     In August 2001, the FASB approved the issuance of FASB statement #144,
"Accounting for the Impairment or Disposal of Long-Lived Assets". This
statement, effective for the Company on January 1, 2002, amends existing
guidance relating to the accounting and reporting of impairments or disposals of
long-lived assets. Management believes that based on its review of the impact of
adopting this standard, there is no significant impact on the carrying values of
existing long-lived assets as of December 31, 2001. In addition, this statement
modifies existing guidance governing the accounting for dispositions of company
assets as discontinued operations in the statement of operations.

  MARCH 31, 2002 UPDATE (UNAUDITED)

     On January 1, 2002, the Company adopted FASB statement #142. Based on
management's review of the impact of adopting this standard, any impairment
charges will be reported as a cumulative effect of a change in accounting
principle. However, this analysis has not been completed to date. Based on the
Company's management plan (see Note 2) to reduce its ownership in AMSG, it is
unclear at this time if the Company would have to take any additional writedown
of the carrying value of its investment in AMSG, as a result of AMSG reporting a
cumulative effect of adopting FASB #142.

     The net medical and other benefits payable above excludes reinsured
reserves of $28,994,000 as of December 31, 2001. Reinsured reserves are
classified as assets on the balance sheet. There were no reinsured reserve
balances as of December 31, 2000. Incurred and paid claims for 2001, related to
prior years, include claims incurred prior to 2001 for BCBSUW and claims
incurred prior to March 31, 2001 for the former UWS companies. A portion of the
reserves for disability claims have been discounted on a tabular basis using the
1987 CDT Table at 7% and 6.5% and waiver of premium claims have been discounted
on a tabular basis using the 1970 Intercompany Group Life Valuation Table at 7%.
The December 31, 2001 loss reserves include $12,667,000 of such discounted
reserves. The amount of discount for case reserves is $4,446,000 at December 31,
2001.

     The Company uses paid claims and completion factors based on historical
payment patterns to estimate incurred claims. Changes in payment patterns and
claims trends can result in changes to prior years' claims estimates.

included in investments, are loaned to third parties, primarily major brokerage
firms. The Company requires a minimum of 102% of the fair value of the loaned
securities to be separately maintained as collateral for the loans. Securities
with a cost or amortized cost of $11,269,000 and $3,782,000 and estimated fair
value of $11,409,000 and $3,866,000 were on loan under the programs at December

6.  INVESTMENT IN AFFILIATES

     Investment in affiliates for 2001 consists of the Company's investment in
AMSG, a leading provider of small group PPO products and life products.
Investment in affiliates for 2000 and 1999 consisted of the Company's investment
in both AMSG and UWS.

INVESTMENT IN AMSG

44% of total AMSG shares outstanding at December 31, 2001 and 2000,
respectively. The Company's recorded investment in AMSG was $78,554,000 and
$97,788,000 at December 31, 2001 and 2000, respectively.

$1,919,000, $1,078,000 and $(9,979,000) in 2001, 2000 and 1999, respectively.
Included in gain (loss) from investment in affiliates in the Company's
consolidated statement of operations for the year ended December 31, 2001, is a
loss of $25,163,000 relating to a writedown of the Company's investment in AMSG
to market value as of December 31, 2001. This writedown was deemed appropriate
based on management's decision to no longer classify the investment in AMSG as a
strategic long-term asset of the Company in December, 2001.

  MARCH 31, 2002 UPDATE (UNAUDITED)

     As a result of the sale of IRG, the condensed UWS consolidated statements
of operations presented above have been restated to report IRG activity as
discontinued operations.

7.  PROVIDER ARRANGEMENTS

     The Company is a party to certain provider arrangements in conjunction with
Unity and Valley, which include profit-sharing payments to certain providers and
repurchase provisions. Management believes that control of Unity and Valley is
not temporary because exercise of the repurchase options is not probable. Any
repurchase would not provide a substantial economic benefit to the option
holders and would require regulatory approval pursuant to change of control
regulations.

     Tax benefits resulting from temporary differences, including NOL's are
required to be recorded as assets to the extent that management believes it is
"more likely than not" that such tax benefits will be realized. A full valuation
allowance was recorded at the date of the Combination for the net deferred tax
assets of UWS, based upon the Company's history of losses and changes in tax
planning strategies post combination. This valuation allowance increased
goodwill by $21,651,000 at the time of the Combination. When management
determines that it is "more likely than not" that the tax benefit of the federal
and state NOL carryovers will be realized prior to their expiration, the
valuation allowance will be reduced. Any reduction of the valuation allowance
recorded at the time of the Combination will be recorded as a reduction to
goodwill. All other reductions to valuation allowances recorded by the Company
will be recorded to income upon reversal.

     As a fiscal intermediary for various government programs, the Company is
subject to regulations covering allowable cost reimbursements and operating
procedures. The laws and regulations governing fiscal intermediaries are complex
and subject to interpretation. The Company believes that it is in compliance
with all applicable laws and regulations and is not aware of any pending or
threatened investigations involving allegations of potential wrongdoing. While
no such regulatory inquiries have been made, compliance with such laws and
regulations can be subject to future government review and interpretation, as
well as significant regulatory actions including fines in excess of fees
received, significant penalties and exclusions from being a government
contractor for these programs.

14.  COMMITMENTS AND CONTINGENCIES

LONG-TERM CONTRACT

     On October 1, 1998, the Company entered into an agreement with a service
bureau to obtain certain electronic data processing services for the Company.
The agreement had an initial term of five years, with options for two additional
one-year renewal periods which have been exercised. Expenses to this service
bureau were $13,405,000, $14,986,000 and $13,945,000 in 2001, 2000 and 1999,
respectively.

OPERATING LEASES

     The Company has operating leases for office space, EDP equipment,
automobiles, software and terminal lines. Future minimum lease payments under
noncancelable operating leases with initial or remaining lease terms in excess
of one year at December 31, 2001 were $38,492,000 in total. Annually, the lease
payments are $9,094,000, $8,627,000, $7,677,000, $5,457,000, $3,448,000 and
$4,189,000 in 2002, 2003, 2004, 2005, 2006 and thereafter, respectively. Rental
expense totaled $13,835,000, $9,538,000 and $13,404,000 in 2001, 2000 and 1999,
respectively.

EXTENSION OF CREDIT

     The Company has an outstanding revolving line-of-credit in the amount of
$15,000,000 available to Health Professionals of Wisconsin, Inc., which
originated in 1997. Interest is accrued based on the quarterly prime rate, with
interest payments due annually on November 1. Interest income amounted to
$308,000 and $451,000 for 2001 and 2000, respectively. The outstanding balance
as of December 31, 2001 and 2000 was $3,000,000 and $4,628,000, respectively.

LITIGATION

     The Company is involved in various legal actions occurring in the normal
course of business. In the opinion of management, adequate provision has been
made for losses which may result from these actions and, accordingly, the
outcome of these proceedings is not expected to have a material adverse effect
on the consolidated financial statements.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

RISKS AND UNCERTAINTIES

     The Company's profitability depends in large part on accurately predicting
and effectively managing health care costs. The Company continually reviews its
premium and benefit structure to reflect its underlying claims experience and
revised actuarial data; however, several factors could adversely affect the
medical cost ratios. Certain of these factors, which include changes in health
care practices, inflation, new technologies, major epidemics, natural disasters
and malpractice litigation, are beyond any health plan's control and could
adversely affect the Company's ability to accurately predict and effectively
control health care costs. Costs in excess of those anticipated could have a
material adverse effect on the Company's results of operations.

15.  SHAREHOLDERS' EQUITY

STATUTORY FINANCIAL INFORMATION (UNAUDITED)

     The Company's insurance subsidiaries are required to file financial
statements with the OCI and other state insurance regulators. Such financial
statements are prepared in accordance with statutory accounting practices
("SAP") prescribed or permitted by the OCI, which differ from GAAP under which
the accompanying consolidated financial statements are prepared. Codification
promulgated by the National Association of Insurance Commissioners ("NAIC") and
adopted by the OCI, took effect on January 1, 2001. Codification impacts the
calculation of statutory surplus for the Company's insurance subsidiaries. The
impact varies by subsidiary with the most significant changes in surplus
resulting from the treatment of deferred tax assets and health care and pharmacy
rebate receivables. The 2001 statutory financial statements reflect a reduction
in statutory surplus of $21,188,000 as a result of implementation of
codification. The Company has taken certain actions including the reallocation
of capital to mitigate the impact of Codification on its insurance subsidiaries.
Significant differences between SAP and GAAP include certain valuations of
investments, calculations of discounted claim reserves, non-recognition of
certain assets (primarily health-care receivables, premium receivables greater
than 90 days, property and equipment and certain intercompany receivable
balances), and recognition of deferred income tax assets based on criteria which
vary from GAAP. While the OCI has the authority to permit insurers to deviate
from prescribed SAP, none of the Company's insurance subsidiaries subject to
oversight by the OCI have received approval to adopt any such practices.

     Selected statutory information by insurance subsidiary is as follows:

     Included in the admitted assets and statutory surplus of BCBSUW is the
$70,000,000 collateralized note obligation due from Cobalt, which is eliminated
in the accompanying financial statements. An extension of the maturity date to
January 2, 2003 of the collateralized note obligation was approved by the OCI on
February 14, 2002 (see Note 11). Pursuant to the terms of the extended note, the
Company must meet certain requirements, including the regulatory approval of all
dividends paid by the Company's

insurance subsidiaries and regulatory approval of all affiliated and material
non-affiliated reinsurance agreements.

     Included in the admitted assets and statutory surplus of Compcare is the
statutory surplus value of UWIC and UHLIC, which are wholly-owned subsidiaries
of Compcare.

     Wisconsin insurance regulations also require the maintenance of a minimum
compulsory surplus based on a percentage of premiums written. As of December 31,
2001, all of the Company's insurance subsidiaries exceeded the regulatory
minimum compulsory surplus, calculated as prescribed by the OCI. In addition,
the Company's insurance subsidiaries are subject to risk-based capital ("RBC")
requirements promulgated by the NAIC. The RBC requirements establish minimum
levels of capital and surplus based upon the insurer's operations and investment
risk. At December 31, 2001, the Company was in compliance with these capital
surplus requirements. In addition, the Company is required to maintain certain
capital and liquidity levels in conjunction with the licensing of certain
products by the BCA. While exceeding the minimum standards to maintain its
license by $15,790,000 and $7,175,000, respectively, for BCBSUW and Compcare,
the Company is subject to ongoing monitoring by the BCA.

     Dividends paid by insurance and HMO subsidiaries are limited by state

  MARCH 31, 2002 UPDATE (UNAUDITED)

     Information disclosed above was revised as a result of certain
reclassifications and adjustments noted in conjunction with the audits of the
Company's insurance subsidiaries' December 31, 2001 statutory basis financial
statements. None of the reclassifications and adjustments noted in conjunction
with the statutory basis audits have any impact on the information reflected in
the accompanying December 31, 2001 GAAP financial statements.

     The 2001 audited statutory basis financial statements reflect a combined
reduction in statutory basis surplus of $16,253,000 as a result of the
implementation of Codification on the Company's insurance subsidiaries.

     In addition, surplus reported in the Company's insurance subsidiaries'
December 31, 2001 audited statutory basis financial statements are as follows:

16.  EMPLOYEE BENEFIT PLANS

PENSION AND POSTRETIREMENT BENEFITS

     The Company and certain of its subsidiaries participate in two defined
benefit pension plans. In conjunction with the Combination, the pension plan
previously named the UWSI/BCBSUW Pension Plan, a multiple employer plan
sponsored by BCBSUW and the former UWS, was amended and renamed

                                       F-31

                               COBALT CORPORATION

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

Cobalt Corporation Pension Plan (the "Plan"). Coincident with the Combination
and the aforementioned Plan name change, the Company assumed the assets and
liabilities of the Plan and became the sole sponsor.

     Effective January 1, 1999, a portion of the assets and liabilities of the
Plan were spun-off to a new UGS Pension Plan (the "UGS Plan"). The UGS Plan
provided retirement benefits for current UGS employees and past retirees,
including benefits accrued prior to 1999, on the same basis as had been provided
under the Plan.

     The Plan and the UGS Plan provide retirement benefits to covered employees
based primarily on compensation and years of service. The Company contributed
$3,514,000 to the UGS Plan in 2001. No contributions were made to any of the
plans in 2000 or 1999.

     The Company also has postretirement benefit plans to provide medical,
dental, and vision benefits and life insurance for certain groups of retired
employees. Such plans were amended in 1997 to limit the Company's financial
contribution in future periods. No benefits will be provided for individuals
hired after the effective dates of these amendments.

     The following financial information includes both the Plan and the UGS
Plan.

     The following table summarizes the change in the pension and postretirement
benefit obligations as of December 31, 2001 and 2000:

     The pension and postretirement plans' assets are comprised primarily of

stock, held by the Plan, with a fair value of $4,466,000 and $2,363,000 at
December 31, 2001 and 2000, respectively. The Plan received dividends in the
amount of $35,000 related to the Cobalt stock held during 2000. No dividends
were paid to the Plan in 2001.

     The 2000 combined ending prepaid pension balance consists of $36,964,000
for the Plan, offset by an accrued pension liability of $493,000 for the UGS
Plan. In 2001, both plans had a prepaid pension balance.

DEFINED CONTRIBUTION AND BONUS PLANS

     The Company participates in defined contribution plans whereby the employer
contributes a percentage of participants' qualifying compensation up to certain
limits, as defined by the plans. The employer match is made in Cobalt common
stock. Employee directed contributions in Cobalt common stock are limited to 30%
of their contributions exclusive of the Company match. The Company also
established various other profit-sharing and bonus programs. Expenses related to
all of these plans totaled $10,612,000, $2,337,000 and $2,128,000 in 2001, 2000
and 1999, respectively.

STOCK-BASED COMPENSATION PLANS

     Certain employees of the Company participated in a stock appreciation
rights ("SAR") plan, based upon the market value of Cobalt common stock. On
December 12, 2001, all 647,390 outstanding SAR's were converted to nonqualified
stock options of an equal number, and at an exercise price equal to the original
strike price of the SAR's. As of that date, 347,890 of the outstanding SAR's
were vested and 281,556 of the SAR's had a strike price lower than the current
market price. The Company recorded expenses of $594,000 for the year ended
December 31, 2001 for the excess of the market value over the strike price as of
the date that the SAR's were converted to options. The SAR liability outstanding
of $544,000 was reclassified to retained earnings upon conversion of the SAR's
to options. These expenses are included in selling, general, administrative and
other expenses in the accompanying consolidated statements of operations.

     Prior to the Combination, the Company had no stock based compensation
programs other than the aforementioned SAR plan. As a result of the Combination,
the Company assumed the stock based compensation plan covering employees and
directors of the former UWS. This plan allows for option grants of up to
4,500,000 shares of common stock as incentive or nonqualified stock options
("NQSOs"). NQSOs vest 25% per year over a four year period.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options, which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Since the Company's employee stock options have characteristics
significantly different from those of traded options and because changes in the
subjective input assumptions can materially affect the fair value estimates, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     The Company follows Accounting Principles Board Opinion No. 25 under which
no compensation expense is recorded when the exercise price of the Company's
employee stock options equals the market

compensation products, along with managed care consulting, electronic claim
submission services, subrogation and hospital bill audit services and
receivables management services. The specialty managed care products and
services are sold throughout the United States. The self-funded products consist
of administrative services and access to Cobalt's extensive provider networks
for uninsured contracts. Government intermediary services include processing
services for Medicare providers throughout the United States and for Medicaid in
the State of Wisconsin.

     "Other continuing operations" include activities not directly related to
the business segments, unallocated corporate items (i.e. gain (loss) from
investment in affiliates, amortization of goodwill for periods prior to January
1, 2002 and unallocated overhead expenses) and intracompany eliminations. The
Company evaluates segment performance based on profit or loss from operations
before income taxes.

     Financial data from continuing operations by segment is as follows:

revenue for the year ended December 31, 2001 and historical revenue for the year
ended December 31, 2000. Investment in unconsolidated affiliates is classified
in other operations.

19.  DISCONTINUED OPERATIONS

     On March 29, 2002, Cobalt sold 100% of the membership interest of its
subsidiary, IRG, for $27 million ($17 million in cash and $10 million in a
three-year note). IRG was one of Cobalt's specialty companies, which provided
behavioral health and medical management services. Accordingly, IRG is accounted
for as a discontinued operation for all periods presented. The purchase
agreement also provides for certain bonuses/penalties to be received/paid
between IRG and Cobalt based on IRG revenues generated from Cobalt in future
years. In addition, the agreement requires certain subsidiaries of Cobalt to
enter into seven-year service agreements for the provision of services by IRG.

     The net gain on discontinued operations for the year ended December 31,
2001, was $1.0 million. Prior to the Combination, there were no operations to
report for discontinued operations for the three months ended March 31, 2001 and
the two years ended December 31, 2000, since IRG was not considered part of
Cobalt for financial reporting purposes until the Combination.

common stock at a price of $13 per share. The aggregate proceeds from the sale

stock by BCBSUW reduces its ownership percentage in AMSG from 45.2% to 39.1%.

ITEM 14.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

     The following is a list of estimated expenses in connection with the
issuance and distribution of the securities being registered, with the exception
of underwriting discounts and commissions:

     All of the above expenses except the Registration fee and NASD filing fee
are estimates. All of the above expenses will be borne by Cobalt Corporation.


ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under Cobalt's Amended and Restated Bylaws and Wisconsin law, Cobalt's
directors and officers are entitled to mandatory indemnification from Cobalt
against certain liabilities and expenses (a) to the extent such officers or
directors are successful in the defense of a proceeding, and (b) in proceedings
in which the director or officer is not successful in the defense thereof,
unless it is determined the director or officer breached or failed to perform
such person's duties to Cobalt and such breach or failure constituted: (i) a
willful failure to deal fairly with Cobalt or its shareholders in connection
with a matter in which the director or officer had a material conflict of
interest; (ii) a violation of criminal law, unless the director or officer had
reasonable cause to believe his or her conduct was lawful or had no reasonable
cause to believe his or her conduct was unlawful; (iii) a transaction from which
the director or officer derived an improper personal profit; or (iv) willful
misconduct. Wisconsin law specifically states that it is the public policy of
Wisconsin to require or permit indemnification, allowance of expenses and
insurance in connection with a proceeding involving securities regulation, as
described therein, to the extent required or permitted as described above.

     Under Wisconsin law, unless its Amended and Restated Articles of
Incorporation provide otherwise, directors of Cobalt are not subject to personal
liability to Cobalt, its shareholders, or any person asserting rights on behalf
thereof for certain breaches or failures to perform any duty resulting solely
from their status as directors, unless the person asserting liability proves
that the breach or failure constituted: (i) a willful failure to deal fairly
with the corporation or its shareholders in connection with a matter in which
the director had a material conflict of interest, (ii) a violation of criminal
law, unless the director had reasonable cause to believe his or her conduct was
lawful or no reasonable cause to believe that his or her conduct was unlawful,
(iii) a transaction from which the director derived an improper personal profit,
or (iv) willful misconduct. Cobalt's Amended and Restated Articles of
Incorporation do not limit a director's immunity provided by Wisconsin law. The
above provisions pertain only to breaches of duty by directors as directors and
not in any other corporate capacity, such as officers. As a result of such
provisions, shareholders may be unable to recover monetary damages against
directors for actions taken by them which constitute negligence or gross
negligence or which are in violation of their fiduciary duties, although it may
be possible to obtain injunctive or other equity relief with respect to such
actions. If equitable remedies are found not to be available to shareholders in
any particular case, shareholders may not have any effective remedy against the
challenged conduct.

ITEM 17.  UNDERTAKINGS.

     The undersigned Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.

                                       II-2


          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus 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.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions set forth in Item 15 hereof, 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 of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

                                       II-3


                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Amendment to the
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Milwaukee, State of Wisconsin, on July 9, 2002.
