Item 1. Business

Introduction

Argonaut  Group,  Inc.  ("Argonaut  Group") is a national  provider of specialty
insurance  products focused on high quality customer service for specific niches
of  property-casualty  insurance.  Workers  compensation  accounted  for  86% of
premiums in 1999 before the  adjustment  to the retro  premium  accrual of $20.0
million.  The information  regarding the retro premium accrual adjustment is set
forth  under the caption  "Management's  Discussion  and  Analysis of Results of
Operations and Financial Condition - Results of Operations" in the Annual Report
to  Shareholders  of Argonaut Group for the fiscal year ended December 31, 1999,
and is  incorporated  herein  by  reference.  See  Exhibit  Index.  See "Item 6.
Selected  Financial Data" for certain financial  information  regarding industry
segments  in which the  Company  operates.  Argonaut  Group is  incorporated  in
Delaware.  Argonaut  Group's  executive  offices are located at 250  Middlefield
Road, Menlo Park, California 94025-3500,  telephone 650.858.6600.  The term "the
Company" refers to Argonaut Group and all its subsidiaries.

Argonaut  Insurance Company ("Argonaut  Insurance"),  Argonaut Group's principal
insurance   subsidiary,   was   established  in  California  in  1948.   Workers
compensation is the primary line of insurance written by Argonaut  Insurance and
its  subsidiaries:   Argonaut-Midwest   Insurance  Company,   Argonaut-Northwest
Insurance Company,  Argonaut-Southwest  Insurance Company, and Georgia Insurance
Company.  Argonaut  Insurance and these  subsidiaries  also write  complementary
lines of  commercial  insurance for a small number of their  clients,  primarily
consisting of general and automobile liability,  but generally targets companies
whose workers  compensation  needs will result in  significant  annual  premiums
(generally  between  $250,000  and $5  million)  in classes of  insurance  which
require specific  expertise to underwrite  prudently,  enhance the safety of the
workplace, and effectively manage losses through partnership with the insured.

Argonaut Great Central Insurance Company  ("Argonaut Great Central") is Argonaut
Group's  other  insurance  subsidiary.  Established  in  Illinois  in  1948  and
purchased  by  Argonaut  Insurance  Company  in  1971,  Argonaut  Great  Central
specializes in providing package insurance policies including property,  general
liability,  workers  compensation,  and umbrella coverage for certain classes of
insureds. Argonaut Insurance is Argonaut Great Central's immediate parent.

AGI  Properties,  Inc. ("AGI  Properties"),  a non-insurance  company,  owns and
leases certain real properties. AGI Properties was incorporated in California in
1970. Argonaut Insurance is AGI Properties' immediate parent.

Products

The  Company has two primary  product  lines:  workers  compensation  insurance
and other  property-casualty  insurance.  Incorporated herein  by  reference
is the  information  appearing  as "Note 10 -  Business  Segments"  in the Notes
to the  Consolidated  Financial Statements of the Annual Report.
See Exhibit Index.

Workers Compensation

Workers  compensation  insurance  is  a  statutory  system  which  provides  for
compensation  of a  policyholder's  employees and their  dependents for injuries
(other than  self-inflicted  wounds) arising out of or suffered in the course of
the employee's  employment,  even though the injuries may have resulted from the
negligence  or wrongful  conduct of the  employee  himself or any other  person.
Workers  compensation  insurance is sold primarily by Argonaut Insurance and its
subsidiaries.  Net earned  premiums for this line of business were $85.7 million
in 1999 (before  adjustment to the retro premium  accrual),  and $115.6 million,
and $140.6 million, in 1998, and 1997, respectively.

Other Property-Casualty Insurance

This   product   includes   general   and   automobile   liability,   commercial
multiple-peril,  and  various  other  insurance  coverages.  Premiums  for these
product lines were $27.3  million,  $22.9 million,  and $24.3 million,  in 1999,
1998, and 1997, respectively.

Argonaut  Insurance offers general and automobile  liability and other insurance
to  commercial  clients in  conjunction  with  workers  compensation  insurance.
Liability  insurance  compensates  third parties for damages  resulting from the
actions of the insured.

Commercial  multiple-peril  insurance,  one of Argonaut Great Central's  primary
products, is a composite product designed for the small-to-medium sized business
which  needs  basic  insurance  coverage  and simple  insurance  administration.
Commercial  multiple-peril policies generally cover property,  plant, inventory,
general liability, and associated coverages.

Ceded Reinsurance

The Company's policy regarding  reinsurance is based upon the  capitalization of
the  subsidiaries.  The goal is to limit the  exposure  to surplus  from  losses
resulting from catastrophes and large or unusually hazardous risks.

As is the case with direct premiums written,  cessions on reinsurance  contracts
are recognized ratably over the period to which the premium relates.

As a result  of an  increase  in  prices  in the  reinsurance  market,  Argonaut
Insurance  increased  the  limit of  retention  on its  primary  excess  of loss
reinsurance treaty from $250,000 to $1,000,000 effective July 1, 1999. Its limit
of retention is $250,000 on its wrap up treaty.  Argonaut Great  Central's limit
of retention  remains the same as the prior year at $500,000 on the property and
liability  treaty,  $300,000 on the First Workers'  Compensation  Excess of Loss
Reinsurance  Treaty  and  $250,000  on  the  First  Underlying  Excess  of  Loss
Reinsurance Treaty.

Incorporated  herein by  reference  is the  information  appearing  as "Note 3 -
Reinsurance" in the Notes to the Consolidated Financial Statements of the Annual
Report. See Exhibit Index.

Competition

The  property-casualty  insurance industry is characterized by a large number of
competing companies and modest market shares by industry participants. According
to A.M.  Best, a leading  insurance  industry  rating and analysis  firm,  as of
December 31, 1998, there are about 2,500  property-casualty  insurance companies
operating  in the United  States,  with the 100  largest  companies  (groups and
unaffiliated)  writing about 80% of the industry's premiums.  Industry wide, net
premiums   earned  totaled   approximately   280  billion  for  1998.   Workers'
Compensation  earned was $25.4  billion or about  9.0% of all  premiums  earned.
(A.M. Best 1999 data is not available yet.)

The Company's principal  competitors cannot be easily classified.  The Company's
principal  lines of  business  are  written  by  numerous  insurance  companies.
Competition  for any one account may come from a very large  national  firm or a
smaller  regional company selling either directly or through agents and brokers.
For the Company's principal line of business,  workers compensation,  additional
competition comes from state workers compensation funds.

Regulation

Since,  1994,  the  Company's  insurance  subsidiaries  have been subject to the
Risk-Based  Capital (RBC) for Insurers Model Act. The RBC calculation takes into
account:  (1) asset risk,  (2) credit risk, (3)  underwriting  risk, and (4) all
other relevant risks. The RBC for Insurers Model Act provides for four levels of
regulatory  authority:  (1) Company Action Level Event,  (2)  Regulatory  Action
Level Event, (3) Authorized Control Level Event, and (4) Mandatory Control Level
Event. These four levels of authority provide for increasing regulatory remedies
for companies that fail to comply with the RBC for Insurers Model Act.

As of  December  31,  1999,  calculations  show  that  the  Company's  insurance
subsidiaries' RBC coverage far exceeds the minimum required.

The Company's  insurance  subsidiaries  are members of the  statutorily  created
insolvency  guarantee  associations  in all states where they are  authorized to
transact  business.  These  associations  were  formed for the purpose of paying
claims of  insolvent  companies.  The Company is assessed  its pro rata share of
such  claims  based  upon its  premium  writings,  subject  to a maximum  annual
assessment per line of insurance.  Such costs can generally be recovered through
surcharges on future premiums.  The Company does not believe that assessments on
current  insolvencies will have a material effect on its financial  condition or
results of operations.

The Company has no policyholder dividend restrictions.

Under the provisions of the California Insurance Code, there is a maximum amount
of  shareholder  dividends  which  can be paid  without  prior  approval  of the
Insurance  Commissioner.  Under  these  provisions,  as of  December  31,  1999,
Argonaut  Insurance  could pay to Argonaut Group a maximum  dividend of $633,000
without the Insurance Commissioner's approval.

Marketing

Argonaut Insurance and Argonaut Great Central operate in substantially different
markets.

Incorporated  herein by  reference  is the  information  appearing  as "Note 1 -
Business and Significant  Accounting  Policies" in the Notes to the Consolidated
Financial Statements of the Annual Report. See Exhibit Index.

Argonaut  Insurance  Company is  authorized  to  operate  in all 50 states.  Its
primary line of business,  workers compensation  insurance,  accounts for 93% of
its total  premiums  (before  adjustment  to the retro premium  accrual).  These
policies are  primarily  written on a  retrospective  rating  basis,  with large
deductible  provisions,  or guaranteed  cost basis.  For  retrospectively  rated
policies,  Argonaut  Insurance's  risk  regarding  inadequate  price  levels  is
mitigated  to a  certain  extent  as the  insured  will  have to pay  additional
premiums (or will be refunded premiums) based upon their actual loss experience.

Argonaut  Great  Central is  authorized  to  operate in 33 states and  considers
itself to be a specialty  company with a defined target  market.  Argonaut Great
Central's   dominant   products  are  commercial   multiple-peril   and  workers
compensation  insurance.  Argonaut Great Central's policies are marketed through
agents.

Neither  Argonaut  Insurance  nor  Argonaut  Great  Central  market any of their
policies through managing general agents.

Run Off Lines

Incorporated herein by reference is the information  appearing as "Note 12 - Run
Off Lines" in the Notes to the Consolidated  Financial  Statements of the Annual
Report. See Exhibit Index.

Loss ratios for the run off line of business are not  meaningful as there are no
current year  premiums  associated  with the current year losses on this line of
business.

Investments

The Company's  investment  portfolio  continues to emphasize  high quality fixed
income  and  equity  investments.  As  a  percentage  of  the  total  investment
portfolio,  U.S.  Treasury  securities  comprise  the  largest  portion  of  the
Company's  holdings.  Obligations  of states  and  political  subdivisions  have
dramatically  decreased  from  1998 as a result of  maturities  and  sales.  The
proceeds  from  these  maturities  and sales  were  reinvested  in high  quality
preferred and common stocks and Other U.S. Agencies (FNMA and FHLM).

The  Company's  investment  policy is to  invest  only in  securities  issued by
investment-grade  issuers.  It does not invest in  high-yield or so called "junk
bonds," derivatives, speculative real estate, or mortgage backed securities.

Incorporated  herein by  reference  is the  information  appearing  as "Note 2 -
Investments"  and  "Note  7 -  Net  Investment  Income"  in  the  Notes  to  the
Consolidated Financial Statements of the Annual Report. See Exhibit Index.

Reserves for Losses and Loss Adjustment Expenses

Incorporated  herein by reference is the information set forth under the caption
"Management's  Discussion  and Analysis of Results of  Operations  and Financial
Condition-Results  of  Operations"  in the  Annual  Report  to  Shareholders  of
Argonaut  Group for the fiscal  year ended  December  31,  1999 and in "Note 4 -
Reserves  for  Losses  and  Loss  Adjustment  Expenses"  in  the  Notes  to  the
Consolidated Financial Statements of the Annual Report. See Exhibit Index.

During the fourth quarter of 1999, the Company  increased  workers  compensation
loss  reserves  by  $31.7  million,  reflecting  higher  than  anticipated  loss
development  for  accident  years  1998 and 1999,  particularly  in  California.
Preliminary  indications  in the first  quarter of 2000 show  continued  adverse
development  of these  accident  years.  If these  trends  continue,  additional
strengthening of these reserves will be required.

Reserves  for  environmental  claims  were $91.3  million  and $96.3  million at
December 31, 1999 and 1998,  respectively.  Reserves  for  asbestos  claims were
$75.3 and $76.6 million at December 31, 1999 and 1998.

In the opinion of management, the Company's reserves for each of these liability
issues represent the Company's best estimate of its ultimate liabilities,  based
on currently  known facts,  current law,  current  technology,  and  assumptions
considered   reasonable   where  facts  are  not  known.   Due  to   significant
uncertainties  and  related  management  judgments,  however,  there  can  be no
assurance  that  future  loss  development,  favorable  or  unfavorable,  can be
accurately predicted.

The following  tables on page 8 and 9 indicate the manner in which  reserves for
losses and loss  adjustment  expenses at the end of a particular  year change as
time  passes.  The first  table  (Table I)  presented  is net of the  effects of
reinsurance. The second table (Table II) presented includes only amounts related
to direct insurance.

The first line  shows the  reserves  as  originally  reported  at the end of the
stated year. The second section shows the cumulative  amounts paid as of the end
of  successive  years  related to those  reserves.  The third  section shows the
original recorded reserves as of the end of successive years adjusted to reflect
facts and circumstances later discovered.  The last line,  cumulative deficiency
or  redundancy,  compares  the adjusted  reserves to the reserves as  originally
established  and shows that the  reserves  as  originally  recorded  were either
inadequate or excessive to cover the estimated cost of claims as of December 31,
1999.

Conditions  and trends that have affected the  development  of these reserves in
the past will not necessarily  recur in the future.  It would not be appropriate
to use this cumulative history in the projection of future performance.

Capital Adequacy

Several  measures  of  capital  adequacy  are  common  in the  property-casualty
industry.  The two most often used are (a)  premium-to-surplus  (which  measures
pressures  on capital from  inadequate  pricing)  and,  (b)  reserves-to-surplus
(which  measures  pressures on capital from  inadequate loss and loss adjustment
expense reserves).

The   following   table   shows   the   consolidated    premium-to-surplus   and
reserves-to-surplus  ratios  of  the  Company's  insurance  subsidiaries  (on  a
statutory basis).

The Company believes that its 1999 capital ratios are satisfactory.

Ratings

The  Company's  insurance  subsidiaries  are rated by A.M.  Best.  A.M.  Best is
generally  considered to be the leading insurance rating agency, and its ratings
are used by insurance buyers,  agents and brokers, and other insurance companies
as an  indicator of financial  strength  and  security,  and are not intended to
reflect  the  quality of the rated  company for  investment  purposes.  Argonaut
Insurance  and its pooled  subsidiaries  has carried an "A+"  (Superior)  rating
since  1991.  Argonaut  Great  Central is rated  separately  and carries an "A-"
(Excellent) rating.

Standard  &  Poor's  currently  rates  the  claims-paying  ability  of  Argonaut
Insurance  and its pooled  subsidiaries  as "AA-" and Argonaut  Great Central as
"A".

Employees

At December 31, 1999,  the Company  employed 372  full-time  employees.  Of this
total, Argonaut Insurance employed 288 people (251  professional/managerial  and
37  clerical/operational).   Argonaut  Great  Central  employed  70  people  (44
professional/managerial and 26 clerical/operational). Argonaut Group employed 14
people (13 professional/managerial  and 1 clerical/operational).  The Company is
not a party to any collective bargaining agreements.

Item 2. Properties

Argonaut Insurance's  headquarters are located in a facility that consists of an
office building on  approximately  two acres of land in Menlo Park,  California.
Argonaut  Great  Central's  headquarters  are  located in a facility  in Peoria,
Illinois.  Argonaut  Insurance  and Argonaut  Great Central own the buildings in
which their headquarters are located. In addition,  the Company has entered into
short term  leases in  conjunction  with its  operations  at  various  locations
throughout  the country.  The Company  believes that its properties are adequate
for its present needs.

Item 3. Legal Proceedings

On August 30, 1996, the Los Angeles County Metropolitan Transportation Authority
(MTA)  filed a civil  action  against  Argonaut  Insurance  alleging  breach  of
contract,  breach of the covenant of good faith and fair dealing, and requesting
ancillary relief in the form of an accounting,  an injunction and restitution in
connection  with  allegations   regarding  failures  to  perform  under  certain
contracts of insurance.

Argonaut Insurance responded to the complaint, and brought certain counterclaims
against the MTA, and possibly  others,  in connection with the facts  underlying
the  lawsuit.  Argonaut  Insurance  believes it has  meritorious  defenses,  and
intends to vigorously contest these claims.  Argonaut Insurance is unable,  with
any degree of  certainty,  to comment upon the range of any  potential  loss, or
whether such an outcome is probable or remote, in light of the limited discovery
conducted in the case, and the investigation conducted thus far.

The Company has been sued in fifteen referenced  lawsuits brought on behalf of
alleged classes of purchasers of  retrospectively  rated worker's  compensation
insurance,  alleging that the defendants,  including other compensation
insurers,  charged the purported class unlawful  premiums.  The lawsuits are
Bristol Hotel Asset  Company,  et al.; v. The Aetna  Casualty and Surety
Company, et al.; Civil Action No. 97-92-I,  pending in the Chancery Court for

National Fire Insurance Co., et al., Case No.  CV98-11695; Superior Court of the
State of Arizona, County of Maricopa, was filed on June 26, 1998.

The Company intends to vigorously defend these lawsuits. Management is unable to
determine the potential financial impact of these lawsuits at this time.

The  insurance  subsidiaries  of the Company are parties to other  various legal
proceedings  which are  considered  routine and incidental to their business and
are not material to the Company's financial condition or results of operations.

Item 4. Submission of Matters to a Vote of Security Holders

YEAR 2000.  The  Company is pleased to report  that it has not  experienced  any
significant  systems  or  other  Year  2000  (Y2K)  problems  at the turn of the
millennium.  During the first hours of  January,  2000,  the systems  department
successfully  completed  a turn  of  century  date  check  out  of all  systems,
applications,  connections,  hardware and software.  All systems continued to be
functional and there were no crisis shutdowns.

                                     Page 13


                                       14
<PAGE>
As of the business week  starting  January 3, 2000 all systems were and continue
to be monitored for any Y2K exceptions. The Company has implemented an extensive
Year 2000 contingency plan that identifies  pre-planned courses of action in the
event  that Y2K  problems  interrupt  its  internal  processes  or its  business
partners'  processes.  As of mid-1999 all third party  vendors and customers had
declared themselves to the Company to be Y2K compliant. As a result there are no
third  parties that are currently  unable to transact  business with the Company
due to Y2K systems  problems.  The  contingency  plan will continue  through the
quarter end of March 2000.

There has been no material  change in total project cost for  upgrading  systems
for Y2K compliance from the approximately $4.4 million previously disclosed. All
costs  associated  with  the  project  have  been  expensed  as  incurred.   The
postponement of known systems projects or other capital spending does not appear
to have any  material  impact on the  company's  liquidity  as the result of the
devotion of company resources to preparing for Y2K compliance.

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial  Accounting  Standard ("SFAS") No. 133,  "Accounting for Derivative
Instruments and Hedging  Activities." SFAS No. 133 requires  companies to record
derivatives  on the  balance  sheet as assets or  liabilities,  measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted  for  depending on the use of the  derivative  and whether it
qualifies for hedge  accounting.  The key criterion for hedge accounting is that
the  hedging  relationship  must be highly  effective  in  achieving  offsetting
changes in fair value or cash flows.  SFAS No. 133 is effective for fiscal years
beginning  after June 15,  1999.  In May 1999,  the FASB  issued  SFAS No.  137,
"Accounting for Derivative  Instruments and Hedging Activities - Deferral of the
Effective  Date of SFAS No.  133",  that  amends  SFAS No.  133 and  defers  the
effective date to fiscal years beginning after June 15, 2000.  Management of the
Company  does not  believe  the  adoption  of SFAS No.  133 will have a material
impact on the  Company's  results  of  operations  or  financial  position  when
adopted.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk

The primary  market  risk  exposures  that result in an impact to the  Company's
investment  portfolio relates to equity price changes and interest rate changes.
The  Company  does  not have  any  foreign  currency  risk,  debt or  derivative
instruments.

The Company holds a well  diversified  portfolio of  investments in common stock
representing  U.S.  firms in industries and market  segments  ranging from small
market  capitalization  stocks to the Standard & Poors 500 stocks.  Equity price
risk is managed primarily through the daily monitoring of funds committed to the
various  types  securities  owned by the Company and by limiting the exposure in
any one investment or type of  investment.  At December 31, 1999 the fair market
value of the Company's  common stock was $427.1  million.  The potential loss in
fair value at December 31, 1999 using a 10% hypothetical  decline in prices,  is
estimated to be approximately $42.7 million.

The  Company's  primary  exposure  to  interest  rate risk  relates to its fixed
maturity  investments  including  redeemable  preferred stock. Changes in market
interest rates directly impact the market value of the fixed maturity securities
and preferred stocks. The following interest rate sensitivity  analysis measures
the potential change in fair value for the Company's fixed maturity  investments
and preferred  stock as of December 31, 1999  resulting from changes in the rate
of 100 and 200 basis points.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULES

To the Shareholders of Argonaut Group, Inc.

We have audited in accordance with generally  accepted auditing  standards,  the
consolidated  financial  statements  included in Argonaut  Group,  Inc.'s annual
report to  shareholders  incorporated  by reference in this Form 10-K,  and have
issued our report  thereon  dated  January 21, 2000.  Our audit was made for the
purpose of forming an  opinion on the basic  consolidated  financial  statements
taken  as a whole.  The  schedules  listed  in Part IV,  Item  14(a)(2)  are the
responsibility  of the  Company's  management  and are presented for purposes of
complying with the Securities and Exchange  Commission's  rules and are not part
of the  basic  consolidated  financial  statements.  These  schedules  have been
subjected  to the  auditing  procedures  applied  in  our  audit  of  the  basic
consolidated  financial statements and, in our opinion, are fairly stated in all
material  respects in relation to the basic  consolidated  financial  statements
taken as a whole.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareholders of Argonaut Group, Inc.

We have audited the accompanying  consolidated balance sheets of Argonaut Group,
Inc. (a Delaware corporation) and subsidiaries as of December 31, 1999 and 1998,
and the related  consolidated  statements of operations,  comprehensive  income,
shareholders'  equity,  and cash flows for each of the three years in the period
ended December 31, 1999. 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 Argonaut Group,
Inc. and  subsidiaries  as of December 31, 1999 and 1998,  and their  results of
operations,  comprehensive  income and cash flows for each of the three years in
the period ended  December 31,  1999,  in  conformity  with  generally  accepted
accounting principles.

ARGONAUT GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements

1. Business and Significant Accounting Policies

Business  Argonaut Group, Inc. (the Company) is a national provider of specialty
insurance products focused on high-quality  customer service for specific niches
of  property-casualty  insurance.  Workers  compensation  is the primary line of
insurance  written  by  Argonaut  Insurance  Company,  the  principal  insurance
subsidiary.   Argonaut  Insurance  Company  also  writes  a  limited  amount  of
complementary  lines of commercial  insurance,  primarily general and automobile
liability, but targets companies whose workers compensation needs will result in
significant  annual  premiums  (generally  between  $250,000  and $5 million) in
classes of insurance which require specific  expertise to underwrite  prudently,
enhance the safety of the  workplace,  and  effectively  manage  losses  through
partnership with the insured.  These classes include  contractors,  wholesalers,
retailers, light manufacturers,  technology firms, service firms (such as in the
hospitality industry), and clients who use self-insurance to meet some or all of
their insurance needs.  Argonaut Insurance Company has also recently announced a
partnership with Esurance to provide  personal auto insurance  nationally on the
Internet (www.esurance.com).

Argonaut   Great   Central   Insurance   Company   specializes   in   commercial
multiple-peril,  workers compensation,  and umbrella coverages  specifically for
food merchants, restaurants, churches, and laundry/dry cleaners.

Basis of Presentation The consolidated  financial  statements of Argonaut Group,
Inc. and subsidiaries  have been prepared in accordance with generally  accepted
accounting  principles (GAAP),  which differ from statutory insurance accounting
practices.  The preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

The financial  statements include the accounts and operations of Argonaut Group,
Inc. and its subsidiaries.  All material  intercompany accounts and transactions
have been eliminated.  Certain prior year balances have been restated to reflect
current year classifications.

For purposes of reporting cash flows, cash and cash equivalents  include cash on
hand and securities with an original maturity of less than ninety days.

Investments  Investments  in fixed  maturities  at  December  31,  1999 and 1998
include bonds, notes, and redeemable preferred stocks. Equity securities include
common and nonredeemable  preferred stocks.  Short-term  investments  consist of
funds which are in excess of the Company's near-term operating and claims-paying
needs and are invested in repurchase  agreements,  commercial  paper,  and money
market funds.

All investments are considered available for sale and are carried at fair value.
Fair values for fixed maturity  investments  and equity  securities are based on
quoted market prices or dealer quotes.  Unrealized  appreciation or depreciation
on  fixed  maturity  investments  and  equity  securities  is  included,  net of
applicable deferred income taxes, in shareholders'  equity.  Gains and losses on
sales of investments are computed on the specific  identification method and are
reflected in total revenue.

Receivables  Receivables  due from  insureds are  presented net of a reserve for
uncollectible accounts of $1.5 million and $1.7 million at December 31, 1999 and
1998 respectively.

Receivables due from  reinsurance of paid loss and loss adjustment  expenses are
presented net of a reserve for  uncollectible  accounts of $4.1 million and $2.6
million at December 31, 1999 and December 31, 1998 respectively.

Accrued  retrospective  premiums are based upon actuarial  estimates of expected
ultimate  losses.  Management  believes that the accrued  retrospective  premium
receivable  is  reasonable.  While the eventual  receivable  may differ from the
current estimates,  management does not believe that this difference will have a
material  effect,  either  adversely or favorably,  on the  Company's  financial
position and results of operations.

Cost in Excess of Net Assets Purchased Cost in excess of net assets purchased of
$32.7  million at December  31, 1999 and $35.9  million at  December  31,  1998,
relate to Teledyne,  Inc.'s  acquisition of Argonaut  Insurance Company in 1969,
and is net of  accumulated  amortization  of $36.9  million  and $34.1  million,
respectively.  Cost in excess of net assets  purchased  is being  amortized on a
straight-line  basis over a 25-year  period  beginning  October 1, 1986. At each
balance  sheet date,  the Company  evaluates the  recoverability  of its cost in
excess of net assets  purchased in relation to anticipated  future cash flows on
an undiscounted basis. If the carrying value of the cost in excess of net assets
purchased exceeds  anticipated future cash flows on an undiscounted  basis, then
the cost in excess of net assets  purchased is deemed to be impaired and written
down to the value of the  anticipated  future cash  flows.  Based on this annual
assessment, the Company expects its cost in excess of net assets purchased to be

Recognition of Premium Revenue & Related  Expenses Premium revenue is recognized
ratably over the period to which the premium relates.  Policy acquisition costs,
included in other assets, consisting primarily of commissions and premium taxes,
are  deferred  and  amortized  over the period in which the  related  premium is
earned.  Deferred  policy  acquisition  costs  are  limited  to their  estimated
realizable  value based on the related  unearned  premium and take into  account
anticipated  claims  and  claims  expenses,  based  on  historical  and  current
experience, and investment income.

Recently Issued Accounting Pronouncements In June 1998, the Financial Accounting
Standards  Board  ("FASB")  issued  Statement of Financial  Accounting  Standard
("SFAS")  No.  133,   "Accounting   for  Derivative   Instruments   and  Hedging
Activities."  SFAS No.  133  requires  companies  to record  derivatives  on the
balance sheet as assets or liabilities,  measured at fair value. Gains or losses
resulting from changes in the values of those derivatives would be accounted for
depending  on the use of the  derivative  and  whether  it  qualifies  for hedge
accounting.  The  key  criterion  for  hedge  accounting  is  that  the  hedging
relationship  must be highly effective in achieving  offsetting  changes in fair
value or cash flows.  SFAS No. 133 was to have been  effective  for fiscal years
beginning  after June 15,  1999.  In May 1999,  the FASB  issued  SFAS No.  137,
"Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective  Date of SFAS No.  133",  that  amends  SFAS No.  133 and  defers  the
effective date to fiscal years beginning after June 15, 2000.  Management of the
Company  does not  believe  the  adoption  of SFAS No.  133 will have a material
impact on the  Company's  results  of  operations  or  financial  position  when
adopted.

The  expected  maturities  may differ from the  contractual  maturities  because
debtors may have the right to call or prepay obligations without penalties.

Proceeds from sales of fixed  maturity  investments  were $61.0  million,  $13.3
million, and $13.0 million in 1999, 1998, and 1997, respectively. Gross gains of
$0.6 million,  $0.2  million,  and $0 and no gross losses were realized on those
sales in 1999, 1998, and 1997, respectively.

At December 31, 1999 the amortized  cost and fair value of bonds on deposit with
various  insurance  regulatory  agencies were $381.4 million and $367.3 million,
respectively.

Additionally,  U.S.  Treasury  Notes with an amortized  cost of $6.8 million and
fair value of $6.5  million were  pledged as  collateral  for surety bonds which
were issued to various states in lieu of depositing bonds.

At December 31, 1999 the  Company's  investment in  International  Paper Company
common stock with a market value of $66.8  million,  was 10.6% of  shareholder's
equity.  At December 31,  1998,  there were no  investments  in any one investee
exceeding 10% of shareholders' equity.

3. Reinsurance

The  Company  reinsures  certain  risks with  other  insurance  companies.  Such
arrangements serve to limit the Company's maximum loss on catastrophes and large
or unusually hazardous risks. The Company is liable for reinsurance ceded in the
event its reinsurers do not meet their  obligations.  The Company's reserves for
nonrecoverable  reinsurance  were $11.2  million and $8.6 million as of December
31, 1999 and 1998,  respectively.  Under certain of the reinsurance  agreements,
funds are held to secure performance of reinsurers in meeting their obligations.
The amount of such funds was $17.6  million and $18.1  million at  December  31,
1999 and 1998, respectively.

Estimated  losses  recoverable from reinsurers and the ceded portion of unearned
premiums are reported as assets.

Losses and loss adjustment expenses of $121.4 million, $95.1 million, and $112.8
million for the years ending  December 31, 1999,  1998, and 1997,  respectively,
are net of  cessions  of  $54.1  million,  $20.7  million,  and  $65.4  million,
respectively.

While the Company is not in the business of assuming  reinsurance  risks,  it is
required to accept certain assigned risks and other legally mandated reinsurance
obligations.

In  previous  years,  the Company  actively  assumed  various  forms of casualty
reinsurance  for  which it  continues  to  maintain  reserves  for loss and loss
adjustment expenses (Note 12).

===============================================================================
</TABLE>
*Restated

Reserves  for  losses  and loss  adjustment  expenses  represent  the  estimated
indemnity cost and related  adjustment  expenses  necessary to  investigate  and
settle  claims.  Such  estimates are based upon  individual  case  estimates for
reported claims,  estimates from ceding companies for reinsurance  assumed,  and
actuarial  estimates for losses which have been incurred but not yet reported to
the insurer. Any change in probable ultimate liabilities is reflected in current
operating results.

As a result of  changes  in  estimates  of insured  events in prior  years,  the
provision for losses and loss adjustment expenses (net of estimated  reinsurance
recoveries of $48.6 million) increased by $57.5 million in 1999 primarily due to
higher than  anticipated  losses and related  expenses for workers  compensation
claims.

The ultimate  cost of claims,  particularly  liability  claims,  is difficult to
predict for several reasons  including:  the uncertain time period for reporting
claims,  changes in the legal  environment and court decisions,  and federal and
state legislation which may dramatically increase the liability between the time
a policy is written and associated claims are ultimately resolved.

As an example,  liability  for exposure to toxic  substances  and  environmental
impairment,  which did not appear  likely or even exist when the  policies  were
written,  has been  imposed by  legislators  and judicial  interpretation.  Tort
liability  has  been  expanded  by  some   jurisdictions   to  cover   defective
workmanship.

Liabilities assumed from other insurance  companies under reinsurance  contracts
are subject to the same factors, and further complicated by long periods of time
between the date of occurrence and the date of the Company's notification of the
claim.

Management   believes  the  reserves  for  loss  and  loss  adjustment  expenses
established are adequate and the associated estimate of reinsurance  recoverable
is reasonable. While the eventual ultimate liability and reinsurance recoverable
may differ  from the current  estimates,  management  does not believe  that the
difference will have a material effect,  either  adversely or favorably,  on the
Company's financial position and results of operations.

The Company discounted certain workers compensation  pension-type reserves using
a maximum  interest  rate of 3.5% in 1999 and 1998.  The  amount of  unamortized
discount was $41.4  million at December  31, 1999 and $35.5  million at December
31, 1998.

Deferred  taxes arise from temporary  differences in the  recognition of revenue
and expenses for tax and financial reporting  purposes.  Net deferred tax assets
(liabilities)  at December 31, 1999,  1998,  and 1997 result from the  following

Realization of deferred tax assets is dependent upon the Company's generation of
sufficient  taxable  income in the future to recover tax benefits that cannot be
recovered  from taxes  paid in the  carryback  period,  generally  three  years.
Although realization is not assured,  management believes it is more likely than
not that all of the  deferred  tax asset  will be  realized.  The  amount of the
deferred tax asset considered realizable,  however, could be reduced in the near
term if estimates of future  taxable income during the  carryforward  period are
reduced.  The Company has a regular federal tax net operating loss  carryforward
of $38.0  million to expire  after 2011,  $16.5  million to expire in 2012,  and
$24.2 million to expire after 2019.

insurance  practices and generally accepted  accounting  principles would not be
available  for  dividends.  At December 31, 1999,  $633,000  was  available  for
dividends to Argonaut  Group without  prior  regulatory  approval.  During 1999,

December 31, 1998.

Stock  Options In August 1986,  the Board of Directors of Argonaut  Group,  Inc.
adopted the Stock Option Plan covering an aggregate 1,500,000 shares of Argonaut
Group,  Inc.  Common Stock.  An amendment to the Plan  increasing  the number of
shares of common stock  issuable  under the Plan from 1,500,000 to 2,000,000 was
approved on April 23, 1996 at the Company's  Annual Meeting.  A second amendment
to the Plan  increasing  the number of shares of common stock issuable under the
Plan from 2,000,000 to 2,500,000 was approved on April 27, 1999 at the Company's
Annual  Meeting.  Under the Stock  Option  Plan,  options to purchase  shares of
Argonaut Group,  Inc. common stock may be granted to certain key employees.  The
options  may be  incentive  stock  options or  nonqualified  stock  options.  If
incentive  options are granted,  the  exercise  price of the options will be the
fair  market  value of the  shares on the date that the option is  granted.  The
exercise price of nonqualified stock options to be granted can be below the fair
market value of the shares on the grant date.  To date all options  granted have
been at the fair market  value of the shares on the date of grant,  and as such,
no  compensation  expense has been recognized as accounted for under APB Opinion
No. 25. The options are nontransferable and are exercisable in installments.

In October,  1995 the Financial  Accounting  Standards Board issued Statement of
Financial Accounting Standard No. 123 "Accounting for Stock-Based  Compensation"
(FAS 123).  As  permitted  by FAS 123, the Company will not change its method of
accounting  for  stock  options  but  has  provided  the   additional   required
disclosures in the tables below.  The additional  compensation  costs that would
have been recorded if the Company had adopted FAS 123 are not material.

At December  31, 1999,  971,090  shares were  available  for future  grant.  The
options are fully vested after 6 years and expire after 11 years.

A summary of the status of the Company's stock option plan at December 31, 1999,
1998, and 1997 is presented in the table below.

The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1999, 1998 and 1997, respectively: risk-free
rates of 4.58% and 5.12% for options issued in 1999, 5.56% and 5.64% for
options issued in 1998, 6.32% and 6.73% for options issued in 1997; expected
dividend yields of 6.66%, 5.43%, and 5.10%; expected lives of 6.21, 6.00, and
6.15 years; and expected volatility of 20.45%, 19.01%, and 16.65%.

Employee Savings Plans  Substantially  all employees of the Company are
eligible to participate in employee savings plans.  Under these plans, a
percentage of an employee's  pay may be contributed to various  savings
alternatives  including, under one plan, investment in the Company's common
stock. The plans call for the Company to match the employee's contribution
under various formulae.  Charges to income related to such Company  matching
were $0.6 million in 1999, $0.7 million in 1998, and $0.6 million in 1997.

10. Business Segments

The Company and its  subsidiaries  are engaged  principally  in the  business of
selling  workers  compensation  and other  insurance.  The  Company's  insurance
subsidiaries  are  authorized  to  sell a  portfolio  of  workers  compensation,
commercial and homeowners multi-peril, automobile liability and physical damage,
medical  malpractice,  fire,  and other lines in all states and the  District of
Columbia.  On June 30, 1997 the  Financial  Accounting  Standards  Board  issued
Statement of Financial  Accounting  Standard ("SFAS") No. 131 "Disclosures About
Segments of an Enterprise  and Related  Information"  effective for fiscal years
beginning  after  December 15, 1997. In accordance  with the selection  criteria
established  by SFAS 131, the Company has  identified  and disclosed as business
segments the lines of business considered significant to the company as a whole.
Net pre-tax  underwriting  loss  represents  net earned  premium less  operating
expenses for each segment,  and excludes  general  corporate  expenses and other
income  and  expenses  of a  general  corporate  nature.  Depreciation,  capital
expenditures, and other assets are not identifiable with any particular segment.
Other  general  corporate  assets  consist  principally  of  investments  (fixed
maturities and equity securities) and receivables (reinsurance,  agents balances
and accrued retrospective premiums).

There are no major  customers  from whom the Company  derives 10% or more of its
revenue.

Information on the Company's  business  segments for the years ended December 31
is as follows.

11. Commitments and Contingencies

Rental  expenses  for  operating  leases,  principally  for  offices,  were $4.0
million, $4.2 million, and $4.0 million in 1999, 1998, and 1997, respectively.

As  of  December  31,  1999,  future  minimum  noncancellable   operating  lease
commitments  are as follows:  $3.8 million in 2000,  $3.1 million in 2001,  $2.3
million in 2002, $1.3 million in 2003, $2.3 million in 2004 and thereafter for a
total of $12.7 million.

The Company's  insurance  subsidiaries  are members of the  statutorily  created
insolvency  guarantee  associations  in all states where they are  authorized to
transact business.  These associations were formed for the purpose of paying the
claims of  insolvent  companies.  The Company is assessed  its pro rata share of
such  claims  based  on  its  premium  writings,  subject  to a  maximum  annual
assessment per line of insurance.  Such costs can generally be recovered through
surcharges on future premiums.  The Company does not believe that assessments on
current  insolvencies will have a material effect on its financial  condition or
results of operations.

On August 30, 1996, the Los Angeles County Metropolitan Transportation Authority
(MTA) filed a civil  action  against the Company  alleging  breach of  contract,
breach of the covenant of good faith and fair dealing,  and requesting ancillary
relief in the form of an accounting, an injunction and restitution in connection
with  allegations  regarding  failures to perform  under  certain  contracts  of
insurance. The MTA contends that it has been damaged by an unspecified amount.

The Company has responded to the Complaint,  and brought  certain  counterclaims
against the MTA, and possibly  others,  in connection with the facts  underlying
the lawsuit.  The Company believes it has meritorious  defenses,  and intends to
vigorously  contest  these  claims.  The  Company is unable,  with any degree of
certainty,  to comment upon the range of any potential  loss, or whether such an
outcome is probable or remote,  in light of the limited  discovery  conducted in
the case, and the preliminary investigation conducted thus far.

The  Company  has been sued in  sixteen  lawsuits  brought  on behalf of alleged
classes of purchasers of retrospectively  rated workers compensation  insurance,
alleging that the defendants, including other compensation insurers, charged the
purported class unlawful  premiums.  Plaintiffs have threatened to bring similar
claims  against the Companies in several other states.  The Companies  intend to
vigorously  defend  these  lawsuits.  Management  is  unable  to  determine  the
potential financial impact of these lawsuits at this time.

The  insurance  subsidiaries  of  the  Company  are  parties  to  legal  actions
incidental to their business. Based on the advice of counsel,  management of the
Company believes that the resolution of these matters will not materially affect
the Company's financial condition or results of operations.

12. Run Off Lines

Although the Company has discontinued active underwriting of hospital liability,
medical malpractice liability, and assumed casualty reinsurance, these lines are
in run off status,  meaning  that the Company is still  obligated  to pay losses
incurred on policies written in past years. Each of these lines is characterized
by long elapsed periods  between the occurrence of a claim and ultimate  payment
of the settled  claim.  The Company has a  specialized  and  dedicated  staff to
administer  and settle  claims  related to these run off  lines.  The  following
tables present the Company's  reserves for losses and loss  adjustment  expenses
and their underwriting loss,  including detailed information for the years ended
December 31.

13.  Permitted Statutory Accounting Practices

The  Company's   insurance   subsidiaries   prepare  their  statutory  financial
statements in accordance  with accounting  practices  prescribed or permitted by
the insurance  departments of the state in which they are domiciled.  Prescribed
statutory accounting practices include a variety of publications of the National
Association  of  Insurance  Commissioners  ("NAIC"),  as  well  as  state  laws,
regulations,  and general  administrative rules.  Permitted statutory accounting
practices  encompass all  accounting  practices not so prescribed  but which the
appropriate regulatory agency has allowed in practice.

The  Company's  insurance  subsidiaries  do not  apply any  permitted  statutory
accounting  practices,  which individually or in the aggregate materially affect
statutory surplus or risk-based capital.

necessary to present fairly the results of operations for such periods have been
made.  Total revenues and net income  include gains on the sale of  investments.
The Company cannot  anticipate when or if similar gains may occur in the future.
Since  financial  results rely heavily on estimates,  caution  should be used in

Management's Discussion and Analysis of Results of Operations and Financial
Condition

Results of Operations  Earned premium income  decreased to $93.0 million for the
year ended  December  31,  1999,  from $138.5  million in 1998,  and from $164.9
million recorded in 1997. This decline resulted from two primary factors: During
the fourth  quarter,  an  actuarial  review  determined  that the  estimate  for
additional premiums accrued under  retrospectively rated policies was overstated
for older policy years by  approximately  $20 million.  The  adjustment  of this
estimate is a decrease to earned  premiums for the quarter and the current year.
Also, severe price competition for workers compensation insurance, the Company's
primary line of business  continued to make many accounts less attractive during
1999.  The impact of large  deductible  programs  on inforce  premium  was $62.0
million in 1999 as compared with $95.3 million in 1998.

Net investment  income was $68.5 million,  $77.4 million,  and $87.2 million for
1999, 1998, and 1997, respectively. This decline reflects fluctuations in market
values  and the  reduction  of  portfolio  assets as claim  reserves  from prior
periods are paid out,  and as funds have been used to  repurchase  shares of the
Company's common stock.

Pre-tax gains on sales of investments were $2.8 million, $51.2 million, and $4.5
million for 1999, 1998, and 1997, respectively. The 1998 gain resulted primarily
from the  call of  Navistar  International  Series D  preferred  stock  and from
resolution  of class action  litigation  related to  investment  trades in prior
years. Management cannot anticipate when or if similar gains or losses may occur
in the future.

Losses and loss  adjustment  expenses  were $121.4  million,  $95.1  million and
$112.8 million in 1999, 1998, and 1997,  respectively.  Incurred losses for 1999
include an increase to workers  compensation  reserves during the fourth quarter
of $31.7  million,  reflecting  higher than  anticipated  loss  development  for
accident years 1998 and 1999,  particularly  in  California.  The Company's loss
ratio,  including the run off lines of business,  was 132% in 1999, 69% in 1998,
and 68% in 1997. The loss ratio in the workers compensation line of business was
143% in 1999 and 65% in both 1998 and 1997.  The loss ratio in other  continuing
lines of business was 102%, 87%, and 94% in 1999, 1998, and 1997, respectively.

In the opinion of  management,  the Company's  reserves  represent the Company's
best  estimate of its  ultimate  liabilities,  based on  currently  known facts,
current law, current  technology,  and assumptions  considered  reasonable where
facts are not known.  Due to significant  uncertainties  and related  management
judgments,  however,  there can be no  assurance  that future loss  development,
favorable or unfavorable, will not occur.

Underwriting  expenses totaled $64.6 million in 1999, $74.9 million in 1998, and
$80.6 million in 1997.  Underwriting  expenses are composed of four  components:
general  expenses,  commissions,  premium taxes, and state fees and assessments.
The $10.3 million  decrease in expenses from the prior year is attributed to the
reduction in compensation  and fringe  benefits paid in 1999, and  non-recurring
expenses related to Year 2000 remediation incurred in 1998.

Policyholder dividend expense (recapture) was $1.0 million in 1999, $0.8 million
in 1998, and $(0.9) million in 1997.  These charges  reflect the loss experience
of  participating  policyholders,  the basis for  dividend  payments.  Since the
advent of open rating in 1995 in California,  fewer  participating  policies are
being written.

After-tax  operating loss was $15.2 million in 1999 compared to operating income
of $62.7 million in 1998 and $48.5 million in 1997.  The after-tax  loss in 1999
was a result  of the  reduction  in earned  premium  and  strengthening  of loss
reserves discussed above.

Liquidity and Capital Resources The Company's insurance  subsidiaries  require a
significant degree of liquidity and adequate capital to meet ongoing obligations
to policyholders and claimants, and to cover ordinary operating expenses. During
the three years ended  December  31,  1999,  the  Company  generated  sufficient
capital from operating and investment income to meet all of its obligations. The
Company  maintains  adequate levels of liquidity and surplus  capacity to manage
the risks inherent with any differences  between the duration of its liabilities
and invested assets.  Management believes that the Company continues to maintain
sufficient liquidity to pay claims and expenses,  as well as to cover unforeseen
events such as reinsurer  insolvencies,  inadequate  premium  rates,  or reserve
deficiencies.

In addition to its investment portfolio, subsidiaries of Argonaut Group own real
property for use as Home Office facilities for Argonaut Insurance Company and
Argonaut Great Central, as well as three commercial properties in California.
These real properties are included in "Other Assets" at $5 million; their
original cost less accumulated depreciation. The market  value for these
properties  is  estimated  at between  $98 and $113 million.

Under provisions of the California  Insurance Code, there is a maximum amount of
dividends   which  can  be  paid  without   prior   approval  of  the  Insurance
Commissioner,  reduced by dividends  declared  during the prior  twelve  months.
Under these provisions, as of December 31, 1999, Argonaut Insurance could pay to
Argonaut  Group,  Inc. a maximum  dividend  of $600,000  without  the  Insurance
Commissioner's  approval.  During  1999,  Argonaut  Insurance  paid the  Company
dividends of $66.4 million.

The quarterly  dividend to shareholders of Argonaut Group for 1999 was $0.41 per
common  share.  During  1999,  total cash  dividends  paid by the Company to its
shareholders were $1.64 per share. On January 22, 2000, the Argonaut Group, Inc.
Board of  Directors  declared a  quarterly  common  stock  dividend of $0.41 per
common share, payable February 23 to shareholders of record February 8, 2000.

During 1999 under its previously  announced stock repurchase program the Company
purchased an additional  1,735,300 shares bringing the total shares  repurchased
to 7,150,988 out of an aggregate  authorization  of eight million shares.  It is
presently expected that dividends received from the Company's  subsidiaries will
be the primary source of funds for the stock repurchase  program and to meet any
other capital requirements the Company may develop.

Recently Issued Accounting Pronouncements  As discussed in Note 1 to the
Consolidated Financial Statements, the Company has  reviewed  Statement  of
Financial  Accounting  Standards  (SFAS) No. 133,  "Accounting  for  Derivatives
and Hedging Activities".  The  statement  will not have a material  effect on
the  Company's  results of  operations  or  financial  condition.  An amendment
to the statement, SFAS No. 137 defers the effective date of SFAS no. 133 for the
Company to January 1, 2001.

Market Risk The primary  market risk  exposures  that result in an impact to the
Company's investment portfolio relates to equity price changes and interest rate
changes. The Company does not have any foreign currency risk, debt or derivative
instruments.

The Company holds a well  diversified  portfolio of  investments in common stock
representing  U.S.  firms in industries and market  segments  ranging from small
market  capitalization  stocks to the Standard & Poors 500 stocks.  Equity price
risk is managed primarily through the daily monitoring of funds committed to the
various  types  securities  owned by the Company and by limiting the exposure in
any one investment or type of  investment.  At December 31, 1999 the fair market
value of the Company's  common stock was $427.1  million.  The potential loss in
fair value at December 31, 1999 using a 10% hypothetical  decline in prices,  is
estimated to be approximately $42.7 million.

The  Company's  primary  exposure  to  interest  rate risk  relates to its fixed
maturity  investments  including  redeemable  preferred stock. Changes in market
interest rates directly impact the market value of the fixed maturity securities
and preferred stocks. The following interest rate sensitivity  analysis measures
the potential change in fair value for the Company's fixed maturity  investments
and preferred  stock as of December 31, 1999  resulting from changes in the rate
of 100 and 200 basis points.

Argonaut  adheres  to  certain  specific  guidelines  to manage  its  investment
portfolio.  The Company invests only in high investment grade bonds ("AAA" rated
U.S.  treasury  notes and  government  agencies and "A" or better for  municipal
bonds and preferred  stocks) with a short horizon (10 year maximum) for treasury
notes, municipal bonds, and government agencies.

Year 2000 The  Company  is  pleased to report  that it has not  experienced  any
significant  systems  or  other  Year  2000  (Y2K)  problems  at the turn of the
millennium.  During the first hours of  January,  2000,  the systems  department
successfully  completed  a turn  of  century  date  check  out  of all  systems,
applications,  connections,  hardware and software.  All systems continued to be
functional and there were no crisis shutdowns.

As of the business week  starting  January 3, 2000 all systems were and continue
to be monitored for any Y2K exceptions. The Company has implemented an extensive
Year 2000 contingency plan that identifies  pre-planned courses of action in the
event  that Y2K  problems  interrupt  its  internal  processes  or its  business
partners'  processes.  As of mid-1999 all third party  vendors and customers had
declared themselves to the Company to be Y2K compliant. As a result there are no
third  parties that are currently  unable to transact  business with the Company
due to Y2K systems  problems.  The  contingency  plan will continue  through the
quarter end of March 2000.

There has been no material  change in total project cost for  upgrading  systems
for Y2K compliance from the approximately $4.4 million previously disclosed. All
costs  associated  with  the  project  have  been  expensed  as  incurred.   The
postponement of known systems projects or other capital spending does not appear
to have any  material  impact on the  company's  liquidity  as the result of the
devotion of company resources to preparing for Y2K compliance.
