ITEM 5.  OTHER EVENTS

    For pro forma and other financial information relating to the proposed 
merger of American Medical Securities Group, Inc. ("AMSG") with and into the 
Registrant, the Registrant hereby incorporates by reference the following 
portions of the Registrant's Registration Statement on Amendment No 1. to 
Form S-4 (File No. 333-10935), as filed with the Securities and Exchange 
Commission on September 17, 1996 (the "Registration Statement"):

    SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF AMSG (including the notes
    thereto) contained on page 8 of the Registration Statement.

    SELECTED HISTORICAL AND PRO FORMA UNAUDITED CONDENSED CONSOLIDATED
    FINANCIAL DATA contained on pages 11 and 12 of the Registration Statement.

    UWS AND AMSG PRO FORMA UNAUDITED CONDENSED CONSOLIDATED FINANCIAL DATA
    (including the notes thereto) contained on page 12 of the Registration
    Statement.

    HISTORICAL AND PRO FORMA UNAUDITED CONDENSED CONSOLIDATED FINANCIAL
    STATEMENTS (including the notes thereto) contained on pages 14 through 25
    of the Registration Statement.

    FINANCIAL STATEMENTS OF AMSG (including the notes thereto) contained on
    pages F-1 through F-18 of the Registration Statement.

    As set forth in note 10 of the foregoing HISTORICAL AND PRO FORMA UNAUDITED
CONDENSED CONSOLIDATED FINANCIAL STATEMENTS, an executive officer of the
Registrant has 7,113 options to purchase AMSG common shares at an option price
of $703, which will be converted in connection with the merger of AMSG into the
Registrant into 301,567 options to purchase common shares of the Registrant, at
an option price of $16.54.  Upon conversion, UWS will record compensation
expense of $2,137,000.  In accordance with Regulation S-X regarding the
preparation of pro forma financial information, this nonrecurring charge has not
been included in the pro forma unaudited condensed consolidated statements of
income incorporated by reference herein.  It is expected, however, that this
nonrecurring charge (which equals approximately $0.13 per common share of the
Registrant's outstanding common shares before giving effect to such merger and
UWS's issuance of shares therein) will be reflected in the Registrant's results
of operations for its fiscal quarter ending September 30, 1996.

                     CONDENSED CONSOLIDATED FINANCIAL DATA

    The following selected historical consolidated financial information of UWS
and AMSG has been derived from their respective historical consolidated
financial statements, and should be read in conjunction with such financial
statements and the notes thereto. UWS's consolidated financial statements are
incorporated by reference in this Joint Proxy Statement/Prospectus. AMSG's
consolidated financial statements are included elsewhere in this Joint Proxy
Statement/Prospectus. The selected historical and pro forma unaudited condensed
consolidated financial information, which gives effect to the Merger as if it
had been consummated on January 1, 1995 for income statement data and on June
30, 1996 for balance sheet data, is derived from the pro forma unaudited
condensed consolidated financial statements included elsewhere in this Joint
Proxy Statement/Prospectus and should be read in conjunction with such
statements and the notes thereto. Adjustments to arrive at the pro forma
consolidated amounts are based on the purchase method of accounting, including
estimates of the approximate fair values of the assets and liabilities of AMSG.


    The pro forma unaudited condensed consolidated financial statements are not
necessarily indicative of the consolidated results of operations or the
financial position that would have been reported had the Merger occurred on the
dates indicated, and should not be construed as representative of future
operations. Furthermore, no effect has been given in the selected historical and
pro forma consolidated income statement data for operating and synergistic
benefits that may be realized through the combination of the entities. See
"HISTORICAL AND PRO FORMA UNAUDITED CONDENSED CONSOLIDATED FINANCIAL
STATEMENTS."

                  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    The following historical and pro forma unaudited condensed consolidated
financial statements of UWS and its subsidiaries as of June 30, 1996 and for the
year ended December 31, 1995 and the six months ended June 30, 1996 illustrate
the effect of the Merger on such financial statements, as though the Merger had
occurred on June 30, 1996 in the pro forma unaudited condensed consolidated
balance sheet and as of January 1, 1995 in the pro forma unaudited condensed
consolidated statements of income. Adjustments to arrive at the pro forma
consolidated amounts are based on the purchase method of accounting, including
estimates of the approximate fair values of the assets and liabilities of AMSG.
The pro forma adjustments and the assumptions on which they are based are
described in the accompanying Notes to Historical and Pro Forma Unaudited
Condensed Consolidated Financial Statements.
 
    The pro forma unaudited condensed consolidated financial statements are not
necessarily indicative of the consolidated results of operations or the
consolidated financial position which would have been reported had the Merger
occurred on the dates indicated or which may be reported in the future.
Furthermore, no effect has been given in the historical and pro forma unaudited
condensed consolidated statements of income for operating and synergistic
benefits that may be realized through the combination of the entities.
 
    The historical and pro forma unaudited condensed consolidated financial
statements should be read in conjunction with the historical consolidated
financial statements of AMSG included herein and the historical consolidated
financial statements of UWS incorporated herein by reference.

             NOTES TO HISTORICAL AND PRO FORMA UNAUDITED CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS

1.  GENERAL
    The pro forma unaudited condensed consolidated balance sheet reflects the
Merger as though it occurred on June 30, 1996. The pro forma unaudited condensed
consolidated statements of income reflect the Merger as though it occurred on
January 1, 1995. The Merger will be accounted for as a purchase transaction.
Certain reclassifications have been made to the AMSG historical consolidated
financial statements to conform to UWS's presentation.
 
    No effect has been given in the pro forma unaudited condensed consolidated
statements of income for operating and synergistic benefits that may be realized
through the combination of the entities.

    UWS currently owns 12% of the common stock of AMSG, and through reinsurance
agreements with AMSIC, UWS retains 50% of the health and life business sold by
AMS on the books of UWIC and UWLIC, insurance subsidiaries of UWS. Under the
terms of the Merger Agreement, UWS will purchase the remaining 88% of AMSG's
common stock for approximately $67.0 million in cash and 3,754,552 newly issued
shares of UWS Common Stock. Upon completion of the transaction, UWS will record
100% of the health and life business sold by AMS.

2.  CASH AND CASH EQUIVALENTS
    Pro forma adjustments to cash and cash equivalents consist of the following:

    The interest rate on the long-term debt incurred to finance the Merger is
expected to be a floating rate based upon the London Interbank market plus
1.25%, which, based upon current rates, would be approximately 6.75%. Each 0.25%
increase or decrease in the floating rate would change annual pro forma
consolidated net income by $114,000 and pro forma earnings per common share by
$0.01 per annum.

</TABLE>

    See Note 2 to Notes to Consolidated Financial Statements of AMSG for a
discussion of the accounting change. The impact of the accounting change is
deemed immaterial to require separate disclosure in the Pro Forma Unaudited
Condensed Consolidated Statements of Income.

21. EARNINGS (LOSS) PER COMMON SHARE

    Pro forma earnings (loss) per common share is based upon the weighted
average number of common shares outstanding during the respective periods,
including the 3,754,552 common shares issued in connection with the Merger.
Since the pro forma condensed consolidated financial statements reflect a net
loss for the year ended December 31, 1995 and the six months ended June 30,
1996, common stock equivalents are not considered in the pro forma calculation
of earnings (loss) per share since they would be anti-dilutive.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
American Medical Security Group, Inc.
 
    We have audited the accompanying consolidated balance sheets of American
Medical Security Group, Inc. (the Company) as of December 31, 1995, and 1994,
and the related consolidated statements of income, shareholders' equity, and
cash flows for each of the three years in the period ended December 31, 1995.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of American
Medical Security Group, Inc. at December 31, 1995 and 1994, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1995, in conformity with generally accepted
accounting principles.
 
    As discussed in Note 2 to the consolidated financial statements, the Company
made certain accounting changes in 1995 and 1994.

1.  ACCOUNTING POLICIES
 
    ORGANIZATION

    American Medical Security Group, Inc. (AMSG) is a holding company for
various subsidiaries involved primarily in the health insurance industry. Third
party administrator (TPA) operations market and administer primarily group life
and health insurance in 32 states and the District of Columbia. Insurance
operations consist of insurance business primarily assumed from a group of
affiliated insurance companies. These insurance risks are administered by AMSG's
TPA subsidiaries. Other consolidated and unconsolidated subsidiaries are
involved in managed care activities, such as health maintenance organizations
and preferred provider organizations.

    The consolidated financial statements include the accounts of AMSG and its
subsidiaries:
 
    - American Medical Security, Inc. (AMS), a third-party administrator
 
    - American Medical Security Insurance Company (AMSIC), a life insurance
      company
 
    - American Medical Security Insurance Company of Ohio (AMSICO), a subsidiary
      of AMSIC

    - American Medical Security Insurance Company of Georgia (AMSICGA), a
      subsidiary of AMSIC

    - Accountable Health Plans of Texas, Inc. (AHP), a preferred provider
      organization

    - American Medical Security Provider Partnerships, Inc. (PPI), a preferred
provider
      organization development company, formed January 1, 1995

    - Continental Plan Services, Inc. (CPSI), a third party administrator
 
    - Unity HMO of Illinois, Inc. (Unity), a 90% owned health maintenance
      organization
 
    Effective January 1, 1995, American Medical Security, Inc. changed its name
to AMSG Inc. and contributed all assets, except for its investments in
subsidiaries to American Medical Security, Inc., a newly formed subsidiary of
AMSG.
 
    BASIS OF PRESENTATION
 
    The accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles (GAAP). Significant
intercompany accounts and transactions have been eliminated.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    INVESTMENTS
 
    Debt securities (bonds) that AMSG has both the positive intent and ability
to hold to maturity are classified as held to maturity and stated at amortized
cost. Debt securities not classified as held to maturity are classified as
available for sale and stated at fair value. Unrealized holding gains and losses
on securities classified as available for sale are stated as a separate
component of shareholders' equity, net of applicable deferred taxes.
 
    Amortization and accretion on bonds are calculated using an effective
interest method. Realized gains and losses on disposals of investments are
determined by specific identification of investments sold. Other invested assets
represent an investment in a real estate partnership (see Note 9), which is
valued at AMSG's share of net equity in the partnership.
 
    Investment in unconsolidated subsidiaries are carried under the equity
method at AMSG's proportionate share of ownership in the subsidiary.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1.  ACCOUNTING POLICIES (CONTINUED)
    PROPERTY AND EQUIPMENT
 
    Property and equipment is recorded at cost and depreciated over the
estimated useful lives of the assets using the straight-line method for
financial reporting purposes and accelerated methods for income tax purposes.
 
    FUNDS HELD BY INSURANCE COMPANIES
 
    Funds held by insurance companies represent amounts on deposit with insurers
related to reinsurance agreements. See Note 6 for further discussion.
 
    INSURANCE CLAIM RESERVES
 
    Insurance claim reserves represent the liabilities arising from life and
health benefits provided under the respective policies. These reserves include
claims in process of adjudication and unreported claims. This liability
represents management's best estimate of the ultimate net cost of all reported
and unreported claims which are not paid at year end. The estimates are
continually reviewed and, as adjustments to these reserves become necessary,
such adjustments are reflected in current operations.
 
    PREMIUMS, ADMINISTRATIVE FEES AND COMMISSIONS
 
    Life and health premiums are recognized as revenue over the periods for
which insurance protection is provided. Administrative fees are recognized as
income as administrative services are provided. Commissions revenue and
commissions expense are recognized on the effective dates of the related
policies.
 
    INCOME TAXES
 
    Deferred income taxes are provided for temporary differences between the
carrying value of assets and liabilities for financial statement purposes and
the amounts used for income tax purposes. The differences relate primarily to
unrealized gains and losses on available for sale investments, tax basis
discounting of loss reserves, capitalization of deferred acquisition costs for
tax purposes and the deferral of certain administration fees for financial
statement purposes.
 
    CASH AND CASH EQUIVALENTS
 
    The Company considers short-term investments with remaining maturities of
three months or less at the date of acquisition to be cash equivalents.
 
    RECLASSIFICATIONS
 
    Certain 1994 and 1993 financial statement amounts have been reclassified to
conform with the 1995 presentation.
 
2.  CHANGE IN ACCOUNTING METHOD
    During 1995, AMSG changed the method of accounting for printed and
promotional materials by recording such materials as inventory and expensing the
materials as they are used in order to better match the expenses to the periods
benefited. Prior to January 1, 1995, all purchases of such materials were
immediately expensed. The effect of the change in accounting was an increase to
1995 net income of $1,236,000, net of taxes of $665,000.
 
    Effective January 1, 1994, AMSG adopted Statement of Financial Accounting
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." Debt securities (bonds) that AMSG has both the positive intent and
ability to hold to maturity are stated at amortized cost. Debt securities that
AMSG does not have the positive intent and ability to hold to maturity and all
marketable equity securities are classified as available for sale and stated at
market value. Unrealized holding gains and losses on securities classified as
available for sale are stated as a separate component of shareholders' equity.
Prior to January 1, 1994, investments in bonds were stated at amortized

cost. The effect of adopting SFAS No. 115 on January 1, 1994, was to increase
shareholders' equity by $1,305,000, resulting from unrealized gains on bonds
available for sale and funds held by insurance companies of $2,007,000, net of
deferred taxes of $702,000. See Note 6 for discussion of funds held balances.

    Liabilities for health insurance claim reserves are based upon actuarial
projections applied to historical claim data. As a result of significant growth
in AMSG's health insurance business, AMSG has experienced variability in the
ultimate settlement of health insurance claim reserves. Actuarial projections of
health insurance claim reserves are continually reviewed and adjusted as
necessary as experience develops and new information becomes available.
 
6.  REINSURANCE
    AMSG administers a block of group life and health insurance business for
UWLIC and United Wisconsin Insurance Company (UWIC) through an administrative
services agreement. The agreement includes maintaining membership records, claim
processing and payment, coordination of benefits and billing/cash collection
processing, underwriting and marketing. In 1995, 1994 and 1993, AMSG earned
administrative fees and commissions of $216,946,000, $170,287,000 and
$109,311,000, respectively under the agreement. UWIC and UWLIC ceded 50% of
their respective life and health insurance risk to AMSIC, a subsidiary of AMSG,
through reinsurance agreements.
 
    During 1992 UWIC ceded 30 percent of its insurance risk to AMSIC. The
reinsurance agreement contained a profit-sharing provision which required the
underwriting gains or losses on the underlying business to be allocated 50
percent to AMSIC. A contingent commission of $1,760,000 was recorded in 1993 in
conjunction with this reinsurance agreement. UWIC and UWLIC generally hold funds
on behalf of AMSIC equivalent to the claim reserves, the accumulated net
underwriting profits and accumulated investment earnings. UWIC and UWLIC pay
interest to AMSIC on the funds held balance at their average portfolio yields.

    The nature of AMSG's deferred tax assets and liabilities are such that the
reversal pattern for those temporary differences should generally result in
realization of the deferred assets. AMSG establishes a valuation allowance for
any portion of the deferred tax asset that management believes may not be
realized. AMSG established a valuation allowance in 1995 and 1994 relating to
undistributed losses from investments in unconsolidated affiliates.
 
    AMSG paid federal income taxes of $1,766,000, $14,768,000 and $10,198,000 in

13. COMMITMENTS AND CONTINGENCIES
    AMSG and its subsidiaries are involved in various legal actions occurring in
the normal course of business. In the opinion of management, adequate provisions
have 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.
 
    During 1993, U&C entered into a mortgage on an office building located in
the Village of Howard, Wisconsin, which is occupied by AMSG under a lease with
an initial term of twelve years. Another mortgage was entered into during 1995
