AMERICAN MEDICAL SECURITY GROUP, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

SEPTEMBER 30, 2003


1.  BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with accounting principles generally accepted in the
United States for interim financial information and with the instructions to
Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all
of the information and footnotes required by accounting principles generally
accepted in the United States ("GAAP") for complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation have been included.
Operating results for the three and nine months ended September 30, 2003 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2003. These condensed consolidated financial statements should be
read in conjunction with the consolidated financial statements and footnotes
thereto included in the American Medical Security Group, Inc. (the "Company")
annual report on Form 10-K for the year ended December 31, 2002.


2.  STOCK-BASED COMPENSATION

The Company has stock-based compensation plans for the benefit of eligible
employees and directors of the Company, which are described more fully in Note
10 in the Company's 2002 Annual Report on Form 10-K. The Company follows
Accounting Principles Board Opinion No. 25, the intrinsic value method of
accounting for stock-based compensation, and no compensation expense is recorded
because the exercise price of the Company's employee stock options equaled the
market price of the underlying stock on the date of grant. The following table
illustrates the pro forma net income and pro forma earnings per share as if the
Company had followed the fair value method of accounting for stock-based
compensation under Statement of Financial Accounting Standards No. 123,
ACCOUNTING FOR STOCK-BASED COMPENSATION ("Statement 123").

</TABLE>

In determining compensation expense in accordance with Statement 123, the fair
value of options was estimated at the date of grant using the Black-Scholes
option valuation model, which is commonly used in estimating the fair value of
traded options that have no vesting restrictions and are fully transferable.
Option valuation models require the input of highly subjective assumptions
including the expected stock price volatility and the expected life of the
options. 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.

3.  DISCONTINUED OPERATIONS

During the third quarter of 2003, the Company sold all of the outstanding common
shares of its preferred provider organization network subsidiary, Accountable
Health Plans of America, Inc. ("AHP") for $3,500,000. The network contracts with
more than 900 hospitals and 100,000 physicians in eight primary states: Arizona,
Florida, Iowa, Nebraska, North Dakota, South Dakota, Texas and Wisconsin.
Subject to the terms of the agreement, AHP will continue to provide network
services to the Company for five years. AHP currently serves approximately 13%
of the Company's members.

The sale transaction resulted in a gain of $1,950,000, or $950,000 net of tax,
which is included in income (loss) from discontinued operations in the Company's
statement of operations for the three and nine months ended September 30, 2003.
Also included in income (loss) from discontinued operations are the net
operating results of the AHP networking business sold. For the nine months ended
September 30, 2003 and 2002, operating results from discontinued operations
included revenues of $1,923,000 and $2,500,000 and income taxes of $118,000 and
$274,000, respectively. As a result of the sale transaction, goodwill on the
Company's balance sheet was reduced by $708,000. All prior periods presented in
the Company's statement of operations have been reclassified to exclude the
results of the discontinued networking business from reported income from
continuing operations.


4.  EARNINGS PER COMMON SHARE ("EPS")

Basic EPS is computed by dividing earnings by the weighted average number of
common shares outstanding. Diluted EPS is computed by dividing earnings by the
weighted average number of common shares outstanding, adjusted for the effect of
dilutive employee stock options.

The following table illustrates the computation of EPS for income from
continuing operations and provides a reconciliation of the number of weighted
average basic and diluted shares outstanding:

===================================================================================================================
</TABLE>

Certain options to purchase shares of common stock were not included in the
computation of diluted earnings per common share for the three and nine months
ended September 30, 2003 and 2002 because the options' exercise prices were
greater than the average market price of the outstanding common shares for the
period.

5.  COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss) is defined as net income (loss) plus or minus other
comprehensive income (loss). For the Company, under existing accounting
standards, other comprehensive income (loss) includes unrealized gains and
losses, net of income tax effects, on certain investments in debt and equity
securities. Comprehensive income (loss) for the Company is calculated as
follows:

6.  NEW ACCOUNTING STANDARD

On January 1, 2002, the Company adopted Statement of Financial Accounting
Standards No. 142, GOODWILL AND OTHER INTANGIBLE ASSETS ("Statement 142").
Statement 142 impacts the Company in two ways. First, goodwill is no longer
amortized. Second, goodwill was subject to an initial impairment test in
accordance with Statement 142, and any remaining balance of goodwill is subject
to continuing impairment testing at least annually. Future goodwill impairments,
if any, will be classified as operating expenses in the Company's statement of
operations. As a result of this initial impairment test, the Company recognized
a non-cash goodwill impairment charge of approximately $60.1 million recorded as
a cumulative effect of a change in accounting principle as of January 1, 2002.
The impairment charge had no impact on cash flows or the statutory-basis capital
and surplus of the Company's insurance subsidiaries.


7.  CONTINGENCIES

In February 2000, a class action lawsuit was filed against the Company in the
state of Florida alleging that the Company failed to follow Florida law when it
discontinued writing certain health insurance policies and offering new policies
in 1998. Plaintiffs claim that the Company wrongfully terminated coverage,
improperly notified insureds of conversion rights and charged improper premiums
for new coverage. Plaintiffs also allege that the Company's renewal rating
methodology violated Florida law. On April 24, 2002, a Circuit Court Judge ruled
against the Company and ordered the question of damages be tried before a jury
at a later date. The earliest the Company expects the trial to be held is the
second quarter of 2004.

The Company is a defendant in a number of lawsuits in various states, primarily
Alabama, alleging misrepresentation of the rating methodology used by the
Company with respect to certain MedOne(R) products purchased by the plaintiffs.
These lawsuits commonly seek unspecified damages for misrepresentation and
emotional distress in addition to punitive damages. Some of these cases involve
multiple plaintiffs. The cases are in various stages of litigation. The Company
believes that these lawsuits are unfounded because the Company properly
disclosed the nature of the products sold. The Company also believes the subject
matter of the lawsuits falls under the primary jurisdiction of state insurance
departments. The Company is vigorously defending itself in these actions.

The Company is involved in various other legal and regulatory actions occurring
in the normal course of business. Based on current information, including
consultation with outside counsel, management believes any ultimate liability
that may arise from the above-mentioned and all other legal and regulatory
actions would not materially affect the Company's consolidated financial
position or results of operations. However, management's evaluation of the
likely impact of these actions could change in the future and an unfavorable
outcome could have a material adverse effect on the Company's consolidated
financial position, results of operations or cash flow of a future period.

8.  SEGMENT INFORMATION

The Company has two reportable segments: 1) health insurance products; and 2)
life insurance products. The Company's health insurance products consist of the
following coverages related to preferred provider organization products:
MedOne(R) (for individuals and families) and small group medical, self funded
medical, dental and short-term disability. Life products consist primarily of
group term life insurance. The "All other" category includes operations not
directly related to the business segments and unallocated corporate items (i.e.,
corporate investment income, interest expense on corporate debt, amortization of
intangibles and unallocated overhead expenses). The reportable segments are
managed separately because they differ in the nature of the products offered and
in profit margins.

The Company evaluates segment performance based on income or loss before income
taxes, excluding gains and losses on the Company's investment portfolio. The
accounting policies of the reportable segments are the same as those used to
report the Company's consolidated financial statements. Significant intercompany
transactions have been eliminated prior to reporting segment information and the
results of discontinued operations have been excluded from all periods
presented.

A reconciliation of segment income (loss) before income taxes to consolidated
income from continuing operations is as follows:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


OVERVIEW

American Medical Security Group, Inc., together with its subsidiary companies
(the "Company"), is a provider of individual and small employer group insurance
products. The Company's principal product offerings are medical insurance for
small employer groups and medical insurance marketed to individuals and their
families ("MedOne(R)"). The Company also offers dental, life, prescription drug,
disability and accidental death insurance, and provides self funded benefit
administration. The Company has two reportable segments: health insurance
products (which accounted for approximately 98% of the Company's total revenues
for the quarters ended September 30, 2003 and 2002) and life insurance products.
The Company markets its products in 32 states and the District of Columbia
through independent agents. The Company has approximately 75 sales managers
located in sales offices throughout the United States to support the independent
agents. The Company's products generally provide discounts to members that
utilize preferred provider organizations with which the Company contracts.

DISCONTINUED OPERATIONS

During the third quarter of 2003, the Company sold all of the outstanding common
shares of its preferred provider organization network subsidiary, Accountable
Health Plans of America, Inc. ("AHP") for $3.5 million. The network contracts
with more than 900 hospitals and 100,000 physicians in eight primary states:
Arizona, Florida, Iowa, Nebraska, North Dakota, South Dakota, Texas and
Wisconsin. Subject to the terms of the agreement, AHP will continue to provide
network services to the Company for five years. AHP currently serves
approximately 13% of the Company's members. Including the sale transaction,
income from discontinued operations was $0.9 million or $0.06 per diluted share
and $0.7 million or $0.05 per diluted share for the three and nine months ended
September 30, 2003, respectively.

RESULTS OF CONTINUING OPERATIONS

The Company reported income from continuing operations of $7.9 million or $0.55
per diluted share for the three months ended September 30, 2003, compared to
income from continuing operations of $5.8 million or $0.42 per diluted share for
the corresponding period in the prior year. Included in the after-tax results of
continuing operations for the three months ended September 30, 2003 are $0.9
million or $0.06 per diluted share of investment gains realized from the sale of
securities during the third quarter. For the nine-month period ended September
30, 2003, the Company reported income from continuing operations of $21.3
million or $1.52 per diluted share, compared with income from continuing
operations of $16.9 million or $1.21 per diluted share for the same period of
the prior year.

INSURANCE PREMIUM REVENUE AND MEMBERSHIP

Insurance premium revenue for the three months ended September 30, 2003
decreased 5.6% to $176.7 million from $187.1 million for the corresponding
period in 2002. For the nine months ended September 30, 2003, insurance premium
revenue declined 6.6% to $534.6 million from $572.3 million in the same period
of the prior year. The decrease primarily resulted from a decline in membership.
Total health membership declined 8.1% from 588,860 members at September 30, 2002
to 540,993 members at September 30, 2003. Management believes the membership
decrease from the prior year is due to several factors, including premium rate
increases resulting in lower new sales and higher lapse rates on existing
business, the continuing effect of negative publicity surrounding the Company's
MedOne(R) rating practices and related legal matters, the difficulty individuals
and small employer groups face in affording increasing health insurance premiums
and the effect of a soft economy with many employer groups ceasing business or
being forced to layoff or downsize their workforce. Partially offsetting the
effect of declining membership was the rise in premium rates on the continuing
block of business. Net realized average fully insured medical premium per member
per month for the third quarter of 2003 increased by 7.0% compared to the third
quarter of 2002.

Management is committed to attaining membership and revenue growth through the
introduction of innovative products designed to meet the changing needs of
today's consumers and through expanded sales support. The Company has introduced
new products with flexible benefit designs and has equipped its sales force with
an innovative tool to help employers manage their health benefit costs in an
inflationary environment. Enhanced customer service programs are also in place
to encourage retention of the Company's existing business. Management believes
these actions may still lead to quarterly revenue and membership growth by the
end of 2003.

NET INVESTMENT INCOME

Net investment income decreased to $3.2 million for the three months ended
September 30, 2003, compared to $3.6 million for the same period in 2002. Net
investment income also decreased for the nine-month period ended September 30,
2003 to $10.0 million from $11.3 million for the same period in the prior year.
The decrease in net investment income is due primarily to a decrease in the
average annualized investment yield. The average annualized investment yield was
4.8% for the first nine months of 2003 compared to 5.5% for the first nine
months of the prior year.

REALIZED INVESTMENT GAINS

During the third quarter of 2003, management took advantage of a market
opportunity and restructured a portion of the company's investment portfolio
resulting in an increase in realized investment gains from the third quarter of
the prior year of $1.4 million. Realized investment gains for the nine months
ended September 30, 2003 were $1.9 million, compared to $0.1 million for the
same nine-month period in 2002.

OTHER REVENUE

Other revenue, which primarily consists of administrative fee income from claim
processing on self funded business and other administrative services, decreased
to $3.9 million for the three months ended September 30, 2003 from $4.2 million
for the three months ended September 30, 2002 resulting from the Company's
decrease in membership. On a year-to-date basis, for the first nine months of
2003, other revenue declined to $11.8 million from $12.8 million for the first
nine months of 2002.

LOSS RATIO

The health segment loss ratio for the third quarter of 2003 was 68.2% compared
to 67.7% for the third quarter of 2002. For the nine months ended September 30,
the health segment loss ratio was 67.9% in 2003, compared to 68.3% in 2002. The
improvement in the health segment loss ratio for the nine-month period is due to
repricing efforts and claims cost control initiatives. Claims costs per member
per month have increased slightly, compared to the same periods in the prior
year, but were surpassed by increased premiums per member per month. The loss
ratio for the life segment, which represents less than 2% of the Company's total
revenues, was favorable at 23.4% for the three months ended September 30, 2003,
compared with 26.8% for the corresponding period of the prior year. For the nine
months ended September 30, the life segment loss ratio was 24.1% in 2003,
compared to 29.8% in 2002. The Company's loss ratio is also impacted by changes
in the estimated cost to settle or resolve claims-related litigation. Management
closely monitors developments in litigation and emerging trends in claims costs
to determine the adequacy and reasonableness of the Company's related reserves,
and adjusts such reserves when necessary.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE RATIO

The selling, general and administrative ("SG&A") expense ratio includes
commissions and selling expenses, administrative expenses (less other revenues),
and premium taxes and assessments. The SG&A expense ratio for the health segment
for the three months ended September 30, 2003 improved to 27.0% compared with
28.5% for the third quarter of the prior year and improved to 27.6% for the nine
month period ended September 30, 2003 from 28.1% reported for the same period of
2002. The improvement was the result of management's efforts to control costs as
revenues declined.


LIQUIDITY AND CAPITAL RESOURCES

The Company's sources of cash consist primarily of insurance premiums,
administrative fee revenue and investment income. The primary uses of cash
include payment of medical and other benefits, SG&A expenses and debt service
costs. Positive cash flows are invested pending future payments of medical and
other benefits and other operating expenses. The Company's investment policies
are structured to provide sufficient liquidity to meet anticipated payment
obligations.

                                       12

<PAGE>


The Company's cash provided by operations was $9.1 million for the three months
ended September 30, 2003, compared to cash provided by operations of $16.1
million for the corresponding period in the prior year. For the nine months
ended September 30, 2003, cash provided by operations was $7.5 million, compared
to $19.5 million provided in the same period of 2002. The decrease in cash flow
in 2003 resulted primarily from prepaid maintenance fees related to the
Company's technology modernization initiatives, a higher level of litigation
settlement payments and a decrease in claim inventories. Consistent with the
Company's historical cash flow trend, management anticipates higher cash flow
during the fourth quarter of the year.

The Company's investment portfolio consists primarily of investment grade bonds
and has limited exposure to equity securities. At September 30, 2003 and
December 31, 2002, greater than 99% of the Company's investment portfolio was
invested in bonds. The bond portfolio had an average quality rating of AA at
September 30, 2003 and December 31, 2002, as measured by Standard & Poor's
Corporation. The majority of the bond portfolio was classified as available for
sale. The Company has no investment in mortgage loans, non-publicly traded
securities, real estate held for investment or financial derivatives.

The Company maintains a revolving bank line of credit agreement with a maximum
available facility of $50.0 million. The agreement provides for a lump-sum
repayment of outstanding advances at the end of 2005. At September 30, 2003, the
outstanding balance of advances under the credit agreement was $30.2 million.
The credit agreement contains customary covenants which, among other matters,
require the Company to achieve certain minimum financial results, prohibit the
Company from paying future cash dividends and restrict or limit the Company's
ability to incur additional debt and dispose of assets outside the ordinary
course of business. The Company was in compliance with all such covenants at
September 30, 2003. The Company's obligations under the credit agreement are
guaranteed by its subsidiary, American Medical Security Holdings, Inc. ("AMS
Holdings"), and secured by pledges of stock of AMS Holdings and United Wisconsin
Life Insurance Company, the Company's principal insurance subsidiary.

The Company's insurance subsidiaries operate in states that require certain
levels of regulatory capital and surplus and may restrict the amount of
dividends that may be paid to their parent company. The insurance regulator in
the insurer's state of domicile may disapprove any dividend which, together with
other dividends paid by an insurance company in the prior 12 months, exceeds the
regulatory maximum, computed as the lesser of 10% of statutory surplus or total
statutory net gain from operations as of the end of the preceding calendar year.
Based upon the financial statements of the Company's insurance subsidiaries as
of December 31, 2002, as filed with the insurance regulators, the aggregate
amount available for dividend without regulatory approval is $11.3 million.

The Company currently does not pay any cash dividends and employs its earnings
in the continued development of its business. The Company's future dividend
policy will depend on its earnings, capital requirements, debt covenant
restrictions, financial condition and other factors considered relevant by the
Company's Board of Directors.

The National Association of Insurance Commissioners has adopted risk-based
capital ("RBC") standards for health and life insurers designed to evaluate the
adequacy of statutory capital and surplus in relation to various business risks
faced by such insurers. The RBC formula is used by state insurance regulators as
an early warning tool to identify insurance companies that potentially are
inadequately capitalized. At December 31, 2002, each of the Company's insurance
subsidiaries had RBC ratios that were substantially above the levels which would
require Company or regulatory action.

In an effort to continue supporting business growth, operational efficiency,
service improvements and future administrative cost savings, the Company's
management approved a plan to invest in an enterprise-wide information
technology modernization project. The project involves the purchase of software
applications and the utilization of internal and external technology and
consulting resources to support most of the Company's major business processes.
The design and development of the software applications began during the first
quarter of 2003, with a phased implementation scheduled over the next three
years.

During the third quarter of 2003, management determined that a portion of the
software being developed for certain insurance operations processes may not be
completed or placed in service in the determinable future due to programming
difficulties. Based on this determination, the capitalized asset relating to
this portion of the modernization project was considered impaired and the costs
previously capitalized were expensed during the third quarter of 2003. Total
expense recognized in the Company's third quarter 2003 statement of operations
was $1.3 million, including $0.7 million of costs that were previously
capitalized during the first two quarters of 2003. Management is in the process
of evaluating its options related to this portion of the systems project and
continues to closely monitor all other capitalized software costs for
impairment. Considering this change, management anticipates total capital
expenditures in 2003 will now be approximately $9.0 million. Management believes
that the Company's existing working capital and operating cash flow will be
sufficient to fund the Company's anticipated capital expenditures related to
this project.

In January 2003, the Company's Board of Directors approved a share
repurchase program, which provides the Company with the authority to repurchase
up to $10.0 million of its outstanding common shares. The plan allows the
Company to buy back its shares, from time to time, in open market or privately
negotiated transactions, subject to price and market conditions. Management
expects the share repurchase program will be funded through operating cash flow.
During the first quarter of 2003, the Company repurchased 52,700 shares of its
common stock at an average market price of $12.46 per share, and at an aggregate
cost of $0.7 million. During the second and third quarters of 2003, the Company
did not repurchase any shares of its common stock.


CAUTIONARY FACTORS

This report and other documents or oral presentations prepared or delivered by
and on behalf of the Company contain or may contain "forward-looking statements"
within the meaning of the safe harbor provisions of the United States Private
Securities Litigation Reform Act of 1995. Forward-looking statements are
statements based upon management's expectations at the time such statements are
made. The Company undertakes no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. Forward-looking statements are subject to risks and
uncertainties that could cause the Company's actual results to differ materially
from those contemplated in the statements. Readers are cautioned not to place
undue reliance on the forward-looking statements. When used in written documents
or oral presentations, the terms "anticipate," "believe," "estimate," "expect,"
"may," "objective," "plan," "possible," "potential," "project," "will" and
similar expressions are intended to identify forward-looking statements. In
addition to the assumptions and other factors referred to specifically in
connection with such statements, factors that could impact the Company's
business and financial prospects include, but are not limited to, those
discussed below and those discussed from time to time in the Company's various
filings with the Securities and Exchange Commission or in other publicly
disseminated written documents:

MEDICAL CLAIMS AND HEALTH CARE COSTS. If the Company is unable to accurately
estimate medical claims and control health care costs, its results of operations
may be materially adversely affected.

The Company estimates the costs of its future medical claims and other expenses
using actuarial methods based upon historical data, medical inflation, product
mix, seasonality, utilization of health care services and other relevant
factors. The Company establishes premiums based on these methods. The premiums
the Company charges its customers generally are fixed for one-year periods, and
therefore, costs the Company incurs in excess of its medical claim projections
generally are not recovered in the contract year through higher premiums.
Certain factors may and often do cause actual health care costs to vary from
what the Company estimated and reflected in premiums. These factors may include,
but not be limited to: (1) an increase in the rates charged by providers of
health care services and supplies, including pharmaceuticals; (2) higher than
expected use of health care services by members; (3) the occurrence of
bioterrorism, catastrophes or epidemics; (4) changes in the demographics of
members and medical trends affecting them; and (5) new mandated benefits or
other regulatory changes that increase the Company's costs. The occurrence of
any of these factors, which are beyond the Company's control, could result in a
material adverse effect on its business, financial condition and results of
operations.

GOVERNMENT REGULATIONS. The Company conducts business in a heavily regulated
industry, and changes in government regulation could increase the costs of
compliance or cause the Company to discontinue marketing its products in certain
states.

The Company's business is extensively regulated by federal and state
authorities. Some of the new federal and state regulations promulgated under the
Health Insurance Portability and Accountability Act of 1996, or HIPAA, relating
to health care reform require the Company to implement changes in its programs
and systems in order to maintain compliance. The Company has incurred
significant expenditures as a result of HIPAA regulations and expects to
continue to incur expenditures as various regulations become effective.

The Company is subject to periodic changes in state laws and regulations
regarding the selection and pricing of risks and other matters. New regulations
regarding these issues could increase the Company's costs and decrease its
premiums. The Company has in the past decided, and may in the future decide, to
discontinue marketing its products in states that have enacted, or are
considering, various health care reform regulations that would impair the
Company's ability to market its products profitably.

                                       14

<PAGE>


Federal and state legislatures also are considering health care reform measures,
which may result in higher health insurance costs. Congress is considering
legislation allowing small employers to form association health plans exempt
from state insurance regulations, which may impact the risk profile of employers
willing to purchase insurance from the Company. In addition, the implementation
of "prompt pay" laws, whereby a claim must be paid in a certain number of days
regardless of whether it is a valid claim or not, subject to a right of
recovery, may have a negative effect on the Company's results of operations.

REGULATORY COMPLIANCE. The Company's failure to comply with new or existing
government regulation could subject it to significant fines and penalties.

The Company's efforts to measure, monitor and adjust its business practices to
comply with the law are ongoing. Failure to comply with enacted regulations,
including the laws mentioned above, could require the Company to pay refunds or
result in significant fines, penalties, or the loss of one or more of its
licenses. The Company has been subject to regulatory penalties, assessments and
restitution orders in a number of states in which it operates. For information
concerning a regulatory proceeding in Florida, see Part II, Item 1, "Legal
Proceedings." From time to time the Company is also subject to inquiries in
other states related to its activities and practices. Furthermore, federal and
state laws and regulations continue to evolve. The costs of compliance may cause
the Company to change its operations significantly, or adversely impact the
health care provider networks with which the Company does business, which may
adversely affect its business and results of operations.

LITIGATION. The Company is subject to class actions and other forms of
litigation in the ordinary course of its business, including litigation based on
new or evolving legal theories, which could result in significant liabilities
and costs.

For example, a Florida Circuit Court has found the Company liable for damages in
a class action lawsuit in Florida. The parties are awaiting the setting of a
trial date to determine damages. Further, the Company is involved in a number of
lawsuits in various states that allege misrepresentation by the Company of its
renewal rating methodology. For additional information, see Part II, Item 1,
"Legal Proceedings."

The nature of the Company's business subjects it to a variety of legal actions
and claims relating but not limited to the following: (1) denial of health care
benefits; (2) disputes over rating methodology and practices or termination of
coverage; (3) disputes with agents over compensation or other matters; (4)
disputes related to claim administration errors and failure to disclose network
rate discounts and other fee and rebate arrangements; (5) disputes over
co-payment calculations; and (6) customer audits of compliance with the
Company's plan obligations.

The Company cannot predict with certainty the outcome of lawsuits against the
Company or the potential costs involved.

COMPETITION. Competition in the Company's industry may limit its ability to
attract new members or to maintain its existing membership in force.

The Company operates in a highly competitive environment. The Company competes
primarily on the basis of price, benefit plan design, strength of provider
networks, quality of customer service, reputation and quality of agent
relations. The Company competes for members with other health insurance
providers and managed care companies, many of whom have larger membership in
regional markets and greater financial resources. The Company cannot provide
assurance that it will be able to compete effectively in this industry. As a
result, the Company may be unable to attract new members or maintain its
existing membership and its revenues may be adversely affected.

BUSINESS GROWTH STRATEGY.  The Company's future operating performance is largely
dependent on its ability to execute its growth strategy.

The Company has experienced a decline in membership over the last several years
as part of its strategy to improve profitability and exit certain markets. The
Company's challenge is to increase the number of individuals and small employer
groups purchasing its products and services while encouraging its current
preferred membership to retain their business relationship with the Company. The
Company has expanded and realigned its sales organization, introduced new
products, established new distribution channels for its MedOne(R) products,
expanded its agent recruitment efforts and developed incentive programs to
improve productivity. Also impacting the Company's growth prospects is the
affordability of health insurance premiums as health care costs rise and the
downsizing or restrained hiring among small employers as a result of economic
uncertainty. If the Company initiatives are not successful and the Company does
not meet its growth goals, the Company's future operating performance may be
adversely affected.

                                       15

INFORMATION SYSTEMS. A failure of the Company's information system could
adversely affect its business.

Information processing is critical to the Company's business. The Company
depends on its information system for timely and accurate information. The
Company's failure to maintain an effective and efficient information system or
disruptions in its information system could cause disruptions in its business
operations, including any of the following: (1) failure to comply with prompt
pay laws; (2) loss of existing members; (3) difficulty in attracting new
members; (4) disputes with members, providers and agents; (5) regulatory
problems; (6) increases in administrative expenses; and (7) other adverse
consequences.

The Company is investing in an enterprise-wide information technology
modernization project involving the purchase of software applications to support
most of the Company's major processes. The design and development of the
software applications began in early 2003, with a phased implementation
scheduled over the next few years. Although the Company is taking measures to
safeguard against disruptions to its information systems during this process, it
cannot provide assurance that disruptions will not occur or that the project
will be successfully implemented or implemented on schedule.

INDEPENDENT AGENT RELATIONSHIPS. The Company depends on the services of
non-exclusive independent agents and brokers to market its products to potential
customers. These agents and brokers frequently market the health insurance
products of competitors as well as the Company's products. Most of the Company's
contracts with agents and brokers are terminable without cause upon 30-days
notice by either party. The Company faces intense competition for the services
and allegiance of independent agents and brokers. The Company cannot provide
assurance that they will continue to market the Company's products in the future
or that they will not refer the Company's members to competitors.

NEGATIVE PUBLICITY. Negative publicity regarding the Company's business
practices and about the health insurance industry may harm the Company's
business and operating results.

In 2002, the Company was subject to negative national publicity surrounding its
MedOne(R) rating practices and related legal matters, which management believes
harmed the Company's MedOne(R) new member enrollment during the last half of
2002. The Company changed its rating practices in all MedOne(R) markets
effective January 1, 2003. Adverse publicity about the Company's rating
practices or other matters in the future may affect sales of the Company's
products, which could impede the Company's growth plans.

In addition, the health insurance industry, in general, has received negative
publicity and does not have a positive public perception. This publicity and
perception may lead to increased legislation, regulation, review of industry
practices and private litigation. These factors may adversely affect the
Company's ability to market its products and increase the regulatory burdens
under which the Company operates, further increasing the costs of doing business
and adversely affecting operating results.

INSURANCE RISK MANAGEMENT. If the Company's insurers or reinsurers do not
perform their obligations or offer affordable coverage with reasonable
deductibles or limits, the Company could experience significant losses.

The Company's risk management program includes several insurance policies it has
purchased to cover various property, business and other risks of loss. In
addition, the Company carries policies to cover its directors and officers. Many
of the carriers marketing these lines of coverage are experiencing unfavorable
claims experience and loss of their own reinsurance coverage. Several carriers
have exited markets and no longer offer certain lines of coverage. Accordingly,
there is no assurance that the Company will be able to purchase insurance
coverages for its own risk management at affordable premiums or with reasonable
deductibles and policy limits.

The Company has entered into and may continue to enter into a variety of
reinsurance arrangements under which it cedes business to other insurance
companies to mitigate large claims risk. Although reinsurance allows for greater
diversification of risk relating to potential losses arising from large claims,
the Company remains liable if these other insurance companies fail to perform
their obligations. As a result, any failure of an insurance company to perform
its obligations under an agreement could expose the Company to significant
losses. Also, there is no assurance that the Company will be able to purchase
reinsurance at affordable premiums.

PERSONNEL. Loss of key personnel and the inability to attract and retain
qualified employees could have a material adverse impact on the Company's
operations.

The Company is dependent on the continued services of its management team,
including its key executives. Loss of such personnel without adequate
replacement could have a material adverse effect on the Company. Members of the
Company's senior management have developed relationships with some of the
Company's independent agents and brokers. If the Company is unable to retain
these employees, the loss of their services could adversely impact the Company's
ability to maintain relations with certain independent agents and brokers who
market the Company's products. Additionally, the Company needs qualified
managers and skilled employees with insurance industry experience to operate its
businesses successfully. From time to time there may be shortages of skilled
labor that may make it more difficult and expensive for the Company to attract
and retain qualified employees. If the Company is unable to attract and retain
qualified individuals or its costs to do so increase significantly, its
operations could be materially adversely affected.

PROVIDER NETWORK RELATIONSHIPS. The Company's inability to enter into or
maintain satisfactory relationships with provider networks could harm
profitability.

The Company's profitability could be adversely impacted by its inability to
contract on favorable terms with networks of hospitals, physicians, dentists,
pharmacies and other health care providers. The failure to secure cost-effective
health care provider network contracts may result in a loss of membership or
higher medical costs. In addition, the inability to contract with provider
networks, the inability to terminate contracts with existing provider networks
and enter into arrangements with new provider networks to serve the same market
or the inability of providers to provide adequate care, could adversely affect
the Company's results of operations.

A.M. BEST INSURANCE RATING. If the Company's insurance subsidiaries are not able
to maintain their current rating by A.M. Best Company, the Company's results of
operations could be materially adversely affected.

The Company's insurance subsidiaries are assigned a rating by A.M. Best Company,
a nationally recognized rating agency. The rating reflects A.M. Best Company's
opinion of the insurance subsidiaries' financial strength, operating results and
ability to meet their ongoing obligations. Decreases in operating performance
and other financial measures may result in a downward adjustment of A.M. Best
Company's rating of the insurance subsidiaries. In addition, other factors
beyond the Company's control such as general downward economic cycles and
changes implemented by the rating agencies, including changes in the criteria
for the underwriting or the capital adequacy model, may result in a decrease in
the rating. A downward adjustment in A.M. Best's rating of the Company's
insurance subsidiaries could cause the Company's agents or potential customers
to look at the Company with less favor, which could have a material adverse
effect on the Company's results of operations.

REGULATION LIMITING TRANSFER OF FUNDS. Regulations governing the Company's
insurance subsidiaries could affect its ability to satisfy its obligations to
creditors as they become due, including obligations under the Company's credit
facility.

The Company's insurance subsidiaries are subject to regulations that limit their
ability to transfer funds to it. If the Company is unable to obtain funds from
its insurance subsidiaries, it will experience reduced cash flow, which could
affect the Company's ability to pay its obligations to creditors as they become
due. The Company will be required to make a lump-sum payment of the total
principal amount of outstanding balances under its credit facility at the end of
2005. The Company's outstanding balance at September 30, 2003 was $30.2 million.
If the Company's insurance subsidiaries are unable to provide these funds, the
Company could default on its obligations under the credit facility.

CAPITAL AND SURPLUS REQUIREMENTS. If the Company's regulated insurance
subsidiaries are not able to comply with state capital standards, state
regulators may require the Company to take certain actions that could have a
material adverse effect on its results of operations and financial condition.

State regulations govern the amount of capital required to be retained in the
Company's regulated insurance subsidiaries and the ability of those regulated
subsidiaries to pay dividends. Those state regulations include the requirement
to maintain minimum levels of statutory capital and surplus, including meeting
the requirements of the risk-based capital standards promulgated by the National
Association of Insurance Commissioners. State regulators have broad authority to
take certain actions in the event those capital requirements are not met. Those
actions could significantly impact the way the Company conducts its business,
reduce its ability to access capital from the operations of its regulated
insurance subsidiaries and have a material adverse effect on its results of
operations and financial condition. Any new minimum capital requirements adopted
in the future through state regulation may increase the Company's capital
requirements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's market risk has not substantially changed from the year ended
December 31, 2002.


ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures designed to ensure that
the information the Company must disclose in its filings with the Securities and
Exchange Commission is recorded, processed, summarized and reported on a timely
basis. The Company's principal executive officer and principal financial officer
have reviewed and evaluated the Company's disclosure controls and procedures as
defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of
1934, as amended (the "Exchange Act") as of the end of the period covered by
this report. Based on such evaluation, such officers have concluded that, as of
September 30, 2003, the Company's disclosure controls and procedures are
effective in bringing to their attention on a timely basis material information
relating to the Company required to be included in the Company's periodic
filings under the Exchange Act. There have been no changes in the Company's
internal control over financial reporting that occurred during the Company's
most recent fiscal quarter that have materially affected, or are reasonably
likely to materially affect, the Company's internal control over financial
reporting.

PART II       OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The following report of recent developments in previously reported legal
proceedings should be read in conjunction with Item 3, Legal Proceedings, in the
Company's annual report on Form 10-K for the fiscal year ended December 31,
2002, and Item 1, Legal Proceedings, in the Company's quarterly reports on Form
10-Q for the quarters ended March 31, 2003 and June 30, 2003.

In May 2001 an administrative complaint issued by the Florida Department of
Insurance was filed against the Company's wholly owned subsidiary, United
Wisconsin Life Insurance Company ("UWLIC") challenging UWLIC's rating and other
practices in Florida relating to its MedOne(R) products for individuals and
their families. In an order entered April 25, 2002, an Administrative Law Judge
recommended dismissal of all counts of the Department's administrative
complaint. On July 24, 2002, the Florida Department of Insurance issued a final
order affirming the recommendations from the Administrative Law Judge with
respect to six of eight counts. However, the Department reversed the
Administrative Law Judge's finding that the Company did not violate state law
applicable to policies issued out of state and ordered the suspension of UWLIC's
license to sell new business in Florida for one year. On April 23, 2003, the
First District Court of Appeals for the State of Florida (the "Court of
Appeals") reversed the order by the Florida Department of Insurance that would
have suspended UWLIC's license. Further, on July 11, 2003, the Court of Appeals
denied the Florida Department of Insurance's request for a rehearing. The Court
of Appeals decision reaffirms the Administrative Law Judge's opinion that
UWLIC's rating practices violated no Florida laws as charged in the complaint.

In a separate action involving substantially similar facts, a class action
lawsuit was filed against two of the Company's wholly owned subsidiaries,
American Medical Security, Inc. ("AMS") and UWLIC in the Circuit Court for Palm
Beach County, Florida, by Evelyn Addison and others in February 2002 alleging
that the Company failed to follow Florida law when it discontinued writing
certain health insurance policies and offering new policies in 1998. Plaintiffs
claim that the Company wrongfully terminated coverage, improperly notified
insureds of conversion rights and charged improper premiums for new coverage.
Plaintiffs also allege that UWLIC's renewal rating methodology violated Florida
law. In a judgment entered April 24, 2002, the Circuit Court Judge in the class
action lawsuit found, among other things, that the policy issued by the Company
outside Florida was not exempt from any Florida rating laws and ordered that the
question of damages be tried before a jury at a later date. The earliest the
Company expects the trial to be held is the second quarter of 2004. The
administrative matter discussed in the preceding paragraph has no direct impact
on the class action lawsuit.

The Company's subsidiaries, AMS and UWLIC, are defendants in a number of
lawsuits in various states, primarily Alabama, alleging misrepresentation of the
rating methodology used by the Company with respect to certain MedOne(R)
products purchased by the plaintiffs. These lawsuits commonly seek unspecified
damages for misrepresentation and emotional distress in addition to punitive
damages. Some of these cases involve multiple plaintiffs. The cases are in
various stages of litigation. The Company believes that these lawsuits are
unfounded because the Company properly disclosed the nature of the products
sold. The Company also believes the subject matter of the lawsuits falls under
the primary jurisdiction of state insurance departments. The Company is
vigorously defending itself in these actions.

The Company is involved in various other legal and regulatory actions occurring
in the normal course of business. Based on current information, including
consultation with outside counsel, management believes any ultimate liability
that may arise from the above-mentioned and all other legal and regulatory
actions would not materially affect the Company's consolidated financial
position or results of operations. However, management's evaluation of the
likely impact of these actions could change in the future and an unfavorable
outcome could have a material adverse effect on the Company's consolidated
financial position, results of operations or cash flow of a future period.

                to update the description of the Company's common stock and
                associated preferred share purchase rights. This description was
                incorporated by reference into the Company's Form S-8
                Registration Statement filed with the Securities and Exchange
                Commission on October 6, 2003, for the Company's Directors
                Deferred Compensation Plan.

        o       A Form 8-K dated November 3, 2003, was submitted on November 3,
                2003, to furnish the Company's earnings release for the quarter
                ended September 30, 2003.
