                              ELECTION OF DIRECTORS

     The  Company's  Articles  of  Incorporation  provide  that  the  number  of
directors will be determined  from time to time by a resolution of a majority of
the Board of Directors. The directors are divided into three classes consisting,
as  nearly  as  possible,  of  one  third  of  the  total  number  of  directors
constituting  the entire Board.  Each class is elected for a three-year  term at
successive annual meetings.  At the Annual Meeting,  the number of directorships
will be nine.

     Three  directors are to be elected for terms of three years and until their
successors are elected and qualified.  Unless otherwise  instructed,  the shares
represented by the enclosed  proxy will be voted for Richard H. Booth,  Colin G.
Campbell and Simon W. Leathes.  In the event any nominee is unable to serve as a
director  on the date of the  Annual  Meeting,  the  proxies  may be voted for a
substitute  nominee  recommended  by the Board of Directors.  A plurality of the
votes cast by the shares  entitled to vote is required  for the election of each
director.

     Mr.  Campbell was elected to his present  term at the 1995 Annual  Meeting.
Mr. Booth and Mr.  Leathes were appointed to the Board in July 1996 and February
1997, respectively.

     Stated  below  are  the  names  and  ages  of the  nominees  and  directors
continuing in office, the principal  occupation of each during at least the last
five years, the date on which each individual was first elected as a director of
the Company, and other directorships and business and civic affiliations of such
persons.  The  information set forth on the following pages with respect to each
nominee's  and  director's   principal   occupation,   other  directorships  and
affiliations and beneficial ownership of Company common stock has been furnished
by the  nominee  or  director.  No  information  is being  provided  for John M.
Washburn,  Jr. and Wilson  Wilde,  who will retire  from the Board of  Directors
effective with the 1998 Annual Meeting in accordance with the Company's Bylaws.

     On June 24,  1997,  all of the  outstanding  shares of common  stock of The
Hartford Steam Boiler Inspection and Insurance Company were exchanged for shares
of common stock of the Company; therefore, references to the Company herein with
dates  prior to June 24,  1997  are  references  to The  Hartford  Steam  Boiler
Inspection and Insurance Company.

Meetings and Remuneration of the Directors

     During 1997,  the Board of  Directors  held nine  meetings and  twenty-four
committee  meetings.  Each director attended at least 75% of the meetings of the
Board and committees on which he or she served combined.

     The  Governance  Committee of the Board of  Directors  has adopted a formal
policy for the  compensation  of  directors  in order to further  link  director
compensation  with the  long-term  interests of  shareholders.  According to the
policy,  director  compensation  should:  a) enable the  Company to attract  and
retain  the  talent  needed  to  fulfill  the  responsibilities  of the Board of
Directors in a superior and independent  fashion;  b) align the interests of the
directors with the long-term interests of shareholders  through stock ownership;
c)  compensate  directors  for their time,  efforts  and  capacity to assist the
Company in the  achievement of its long-term  goals;  and d) be validated in its
efficacy through review by an independent compensation consultant.

     The annual  retainer for each director who is neither a present nor retired
employee  of the  Company  or of a  subsidiary  is  $15,000.  Each  non-employee
director  is paid a fee of  $1,200  for  attendance  at a Board  or a  committee
meeting and an additional $350 for each committee meeting chaired. Directors who
are present or retired  employees of the Company or a subsidiary  do not receive
such  compensation  for service on the Board or  committees  thereof and are not
eligible to participate in the plans described below for non-employee directors.
Non-employee  directors  are not  eligible  to  participate  in any of the plans
discussed in the Human  Resources  Committee  Report on Executive  Compensation.
Directors may be reimbursed for reasonable travel expenses incurred in attending
Board and committee meetings.

     Each non-employee  director received an award of 550 stock equivalent units
under the Directors Stock and Deferred  Compensation Plan (the "Directors Plan")
for the 1997 plan year. The Directors Plan was amended effective January 1, 1998
to  provide  that  future  awards  will  be made in the  form of 550  shares  of
restricted stock. (If an award would be currently taxable to a director based on
the laws of the country in which such director is located,  the award will be in
the form of 550 stock equivalent units.) Restricted stock awarded under the plan
is  forfeitable  until such time as the  director  retires  after age 70,  dies,
becomes  disabled,  resigns  in  certain  circumstances  with the  consent  of a
majority of the board of directors,  or upon a change in control of the Company,
whichever event occurs earliest.

     Under the Directors Plan, a director may elect to defer payment of all or a
portion of his or her cash compensation  (annual retainer and meeting fees) to a
future date  specified by the director.  A  participating  director may elect to
have  amounts held in his or her deferred  account (i)  credited  annually  with
interest  (accrued  at the rate of the  average  of the  yields at  issuance  of
five-year U.S. Treasury Notes issued during the prior  twelve-month  period plus
1%) on the average daily  balance held in such  accounts for the preceding  plan
year;  or (ii)  converted  into stock  equivalent  units or shares of restricted
stock  equal to the amount of  deferred  cash  compensation  divided by the fair
market  value  of  Company  common  stock on the date  such  compensation  would
otherwise have been paid.

     Stock  equivalent  unit and cash account  balances held under the Directors
Plan are paid out in cash or Company  common  stock,  either in a lump sum or in
installments,  at the  director's  election.  For the 1997 plan  year,  dividend
equivalents,  in an amount equal to the amount of dividends that would have been
payable had each stock  equivalent  unit  credited to a director  constituted  a
share of Company  common  stock,  were payable in cash  following the end of the
plan  year.  Beginning  with the 1998  plan  year,  directors  may elect to have
dividend  equivalents paid in cash or converted into additional stock equivalent
units or shares of restricted stock following the end of the plan year.

     In 1992 the Board of Directors  established a Charitable  Endowment Program
for members of the Board of Directors who have at least one year of service as a
director.  A portion of the program is currently  funded by life insurance.  The
Company intends to make tax deductible charitable contributions of $1 million to
charities  recommended  by each  director,  paid out over a period  of ten years
following the death of the director.  Directors derive no financial benefit from
the program since any insurance proceeds and charitable deductions accrue solely
to the Company.

     The Company's Board of Directors  annually  appoints  certain  directors to
serve on standing committees of the Board of Directors,  which currently include
the Audit, Human Resources, Governance, Finance and Executive Committees.

     The Audit Committee's primary responsibility is to review and report to the
Board on the Company's  accounting  policies,  the adequacy of its financial and
internal  auditing  controls,  and  the  reliability  of  financial  information
reported to the public.  The Committee has the authority to approve the scope of
the annual audit and to authorize  the release of annual  financial  statements.
The Audit Committee held four meetings during 1997. Mr. Ferland (Chairman),  Mr.
Booth, Mr. Leathes and Mr. Washburn,  none of whom is an employee of the Company
or a subsidiary, presently serve on the Audit Committee.

     The  Human  Resources  Committee  reviews  remuneration  for the  Company's
executives  as described in the Human  Resources  Committee  Report on Executive
Compensation  located on page 8. The  Committee  reviews the  Company's  benefit
plans and  policies  and  practices  with  respect to  employee  relations.  The
Committee  acts as Plan  Administrator  for the 1985 Stock Option Plan, the 1995
Stock Option Plan, the Directors Stock and Deferred  Compensation  Plan, and the
Long-Term and Short-Term Incentive Plans. The Human Resources Committee held six
meetings during 1997. Mr. Ellis (Chairman),  Mr. Campbell,  Mr. Leathes and Mrs.
Rice,  none of whom is an  employee of the  Company or a  subsidiary,  presently
serve on the Human Resources Committee.

     The Governance  Committee  reviews the  organization and performance of the
Board of  Directors  and  reviews  and  recommends  director  compensation.  The
Committee  also reviews the  Company's  policies and  practices  with respect to
community  relations and recruits and nominates  candidates for Board membership
in  conjunction  with  the  Chief  Executive  Officer.  In  accordance  with the
Company's Bylaws,  any nomination by a shareholder must have been made by proper
written notice given to the Corporate Secretary not later than February 23, 1998
in order to be considered for the 1998 Annual Meeting.  The Governance Committee
held five meetings during 1997. Mr. Campbell (Chairman), Mr. Alvord, Mr. Dooley,
Mr.  Ellis  and Mrs.  Rice,  none of whom is an  employee  of the  Company  or a
subsidiary, presently serve on the Governance Committee.

     Other  committees of the Board of Directors  are the Finance  Committee and
the Executive  Committee.  The Finance  Committee reviews the investment plan of
the Company,  investor  relation  activities,  and other  matters  involving the
Company's financial resources. Mr. Dooley (Chairman), Mr. Alvord, Mr. Booth, Mr.
Ferland  and Mr.  Washburn,  none of whom is an  employee  of the  Company  or a
subsidiary,  presently serve on the Finance Committee,  which held nine meetings
in 1997. The Executive Committee acts on behalf of the Board of Directors in the
interim between  meetings of the Board when prompt,  formal action is necessary.
Mr. Wilde (Chairman),  Mr. Alvord,  Mr. Campbell,  Mr. Dooley, Mr. Ellis and Mr.
Ferland presently serve on the Executive Committee, which did not meet in 1997.

        The Company is unaware of any  shareholder  who on February 17, 1998 was
the beneficial  owner of 5 percent or more of Company  common stock  outstanding
except as noted in the following table.

(1) On December  31, 1997,  the Company and  Employers  Reinsurance  Corporation
("ERC")  entered into a Purchase  Agreement  pursuant to which a business  trust
formed by the Company sold $300 million of 7% convertible  subordinated  capital
securities to ERC. The securities are  convertible  into the common stock of HSB
Group,  Inc.  at $85 a share at any time,  subject to  regulatory  approval,  or
approximately  3,529,412 shares of common stock of the Company, which on a fully
diluted  basis  would  constitute  15.3% of the  Company's  outstanding  shares.
Pursuant to the Purchase Agreement, ERC has agreed to vote any shares

                                       6

acquired upon  conversion with respect to certain matters in accordance with the
recommendations  of the  Company's  Board of  Directors,  or, in the event  such
agreement is held invalid or in violation of any law, in the same  proportion as
the Company's other holders of voting securities.

     The  number of shares of  Company  common  stock  beneficially  owned as of
February 17, 1998 by each nominee and director,  by each executive officer named
in the Summary  Compensation  Table,  which in each case,  other than Mr.  Kreh,
represents less than 1% of the Company common stock outstanding as of such date,
and by all current directors and executive  officers as a group, is shown in the
table below.  Assuming the exercise of all currently  exercisable  options,  Mr.
Kreh would  beneficially  own 1.7% of Company  common  stock as of February  17,
1998. The table also sets forth the number of stock equivalent units credited to
non-employee  directors  participating  in  the  Directors  Stock  and  Deferred
Compensation Plan, which is explained in detail on page 5. Individuals are fully
at risk as to the  value  of  stock  equivalent  units  held in  their  deferred
accounts, which will be converted to an equal number of shares of Company common
stock, or their equivalent cash value, at the election of the director, upon his
or her termination of board service.

     Unless  otherwise  indicated,  each officer,  nominee and director has sole
voting and  investment  power (or shares such powers with a family  member) with
respect to Company common stock shown as held directly. All shares shown as held
indirectly  reflect sole voting and investment power exercised by the individual
specified unless otherwise indicated.

1934.  To the  Company's  knowledge,  based  solely on a review of the copies of
reports that were furnished to the Company and written  representations  that no
other reports were required,  all required  reports were made in a timely manner
with respect to the fiscal year ended December 31, 1997.


HUMAN RESOURCES COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     Executive  compensation  programs for the Senior Vice  Presidents and Chief
Executive  Officer of the Company (the  "executives")  are  administered  by the
Human  Resources  Committee  of the  Board of  Directors  (the  "Committee").  A
nationally  recognized  compensation  consultant  also  reviews and analyzes the
Company's executive  compensation  policies and practices in order to advise the
Committee  as more  fully  described  below.  The  Committee  believes  that the
structure of the Company's  compensation programs provides a direct link between
Company performance and executive compensation.

     Under the direction of the Committee,  executive  compensation programs are
structured  to provide  performance-based  incentives  to achieve the  Company's
short and long-term  goals,  and to enable the Company to attract and retain key
individuals.  In 1997, two groups of comparison companies were used to determine
competitive  executive pay levels and  practices.  Comparison  Group I, used for
reviewing  competitive  pay levels for  executives,  was  composed of 18 leading
property/casualty  insurance  companies  (including  five of the eight insurance
companies  in  the  S&P  500  Property/Casualty  Insurance  Index  used  in  the
Performance Graphs located on page 17).  Comparison Group II, used for reviewing
competitive  compensation practices, was composed of the top twenty companies on
Fortune's list of most admired  companies (none of which are included in the S&P
500 Property/Casualty  Insurance Index used in the Performance Graphs located on
page  17).  Compensation  practices  analyzed  included  the  level  and  mix of
compensation  components,  actual and targeted  stock  ownership  levels and the
design of short and long-term incentives.  In assessing competitive compensation
practices,  the Committee believes that it is appropriate to review compensation
practices at high-performing, well-run companies.

     Base salary and variable  compensation  paid under the Company's  incentive
plans (Short-Term and Long-Term  Incentive Plans and the 1995 Stock Option Plan)
in 1997 to executives as a group, and for Mr. Kreh individually,  were below the
median range of that paid to executives  by the companies in Comparison  Group I
according to information compiled by the Company's compensation  consultant.  It
is the  Committee's  intent to target future  compensation  in the median of the
range of that paid to executives by the companies in Comparison Group I.

     Base salary  adjustments are made for executives  based upon an analysis of
individual  performance,  changes in responsibilities,  and comparative data for
base  salaries paid to executives  with similar  responsibilities  in Comparison
Group I. Annual salary  adjustments  for executives are recommended by the Chief
Executive  Officer  and  approved  by  the  Human  Resources  Committee  in  its
discretion. The Committee determines adjustments for the Chief Executive Officer
in its discretion.  For 1997, base salary  adjustments for executives other than
Mr.  Kreh  were  made  for  competitive  reasons  based  upon  comparisons  with
Comparison Group I. Mr. Kreh received a 29.63% base salary increase based on the
Committee's  analysis  of  the  comparative  data  for  base  salaries  paid  to
executives with similar responsibilities in Comparison Group I.

     The Company's  Short-Term  Incentive  Plan provides for the annual award of
bonuses to officers of the  Company,  including  the  executives,  and any other
employees  designated by the Committee,  based upon the Company's  attainment of
certain net income per share targets,  and other operating results.  The plan is
proposed to be amended in order to assure  objective  criteria  for  determining
annual  formula-based  awards to qualify them for a deduction under the Internal
Revenue  Code as  described  in  detail  beginning  on page  17.  The  following
description is applicable to awards made for the plan year ending in 1997.

     For 1997, the Committee  evaluated  Company results  achieved for growth in
revenue, growth in operating income,  insurance combined ratio, return on equity
and engineering services' margin, as compared,  where appropriate,  to published
results achieved or anticipated for the property/casualty  insurance industry as
a whole.  In 1997,  the  Actual  Percentage  of  Budgeted  Net  Income Per Share
exceeded the target level set by the  Committee at the beginning of the year. In
1997, the Committee determined that the Company  substantially  outperformed the
property/casualty  insurance  industry for return on equity,  insurance combined
ratio and revenue growth (the Company's  return on equity for 1997 was 19.1% and
the insurance combined ratio was 91.7%). Mr. Kreh was awarded $700,000 under the
plan based on the Committee's  evaluation of Mr. Kreh's  contributions  to these
results.  The Committee  determined the total dollars available for awards under
the plan and Mr. Kreh determined the executives'  awards for 1997,  based on his
evaluation of 1997 results and each executive's contributions to such results.

     If shareholders  approve the proposed  amended  Short-Term  Incentive Plan,
payouts  beginning  with the one for the 1998 plan  year will be made  under the
terms of the amended plan as described beginning on page 17.

     Long-term  incentives are provided to executives  through awards made under
the Company's  Long-Term  Incentive  Plan. The plan is proposed to be amended as
described  beginning on page 19. The  following  description  is  applicable  to
awards made for the 1995-1997  Performance Period. Under the plan, the Committee
establishes specific Performance Goals for each participant (or all participants
as a group) at the beginning of each Performance  Period based on one or more of
the following Performance Measures: insurance combined ratio; expense ratio; net
income per share; return on equity; total shareholder return;  return on assets;
revenues;  engineering  services'  margin;  increase in book  value;  and market
share.  For each Performance  Goal, an award schedule of Performance  Contingent
Units is established  for minimum,  target and maximum  attainment of such goal,
based on a percentage  of a  participant's  base salary rate at the beginning of
the period  (adjusted  for any  promotional  increases  during  the  Performance
Period)  divided by the  average of the high and low  trading  prices of Company
common stock on the first trading date of the Performance Period.

     The actual Performance  Contingent Award to be paid to a participant at the
conclusion of the Performance  Period is based on the level of attainment of the
Performance  Goals  established  for  such  period.  If  the  minimum  level  of
achievement is not reached for any of the Performance Goals, the payout is zero.
Payments  made  under  the  plan  relating  to  any  Performance  Period  for  a
participant may not exceed $1 million.  Awards are prorated for actual length of
service as an eligible executive during the Performance Period. Any payments are
made in cash or in shares of  Company  common  stock  (which  may be  restricted
shares),  as determined by the  Committee.  At the  discretion of the Committee,
dividend  equivalents  may be paid in conjunction  with award payouts made under
the plan, equal to the amount of cash dividends that would have been paid during
the Performance Period with respect to an award of Performance  Contingent Units
if the award had been made in Company  common  stock.  The current plan provides
for  Performance  Periods of three  years.  As  explained  in more detail  under
Proposal No. 3, beginning on page 19, the revised plan provides for  Performance
Periods of three years, or such other duration as set by the Committee. However,
in order to  gradually  phase  in the new  program,  the  revised  plan  will be
implemented with two shorter initial  Performance Periods which will end in 1998
and 1999, if the plan as amended is approved by  shareholders at the 1998 Annual
Meeting.  Performance  Measures for these Performance Periods will be set during
the ninety day period  provided for under Internal  Revenue Code Section 162(m),
but had not yet been set by the  Committee  at the time of  preparation  of this
report.

                                       9
<PAGE>

     The  Committee  determined  that  payouts to be made under the plan for the
Performance Period ending in 1997 would be made in shares of restricted stock in
order to further link executives'  interests with long-term Company performance.
These  shares  cannot  be sold or  transferred  and  will  be  forfeited  if the
executive  leaves the Company  within a period of five years for  reasons  other
than  death,  disability,  retirement,  involuntary  termination  other than for
cause, or resignation  with the consent of the Human Resources  Committee of the
Board of Directors of the Company.

     For the  three-year  Performance  Period  ending  in  1997,  the  Committee
established  specific  Performance  Goals at the  beginning  of the  Performance
Period  based on the  following  Performance  Measures:  net  income  per share,
expense ratio and return on equity. For each Performance Goal, an award schedule
of Performance Contingent Units was established for minimum,  target and maximum
attainment of such goals, based on a percentage of the participant's base salary
rate at the  beginning of the period  (adjusted  for any  promotional  increases
during the period), divided by the average of the high and low trading prices of
Company common stock on January 3, 1995.  For the 1995 through 1997  Performance
Period,  the net income per share  threshold was not met and the expense  ratio,
and the return on equity targets were exceeded.  Awards made to executives under
the plan for the  three-year  Performance  Period ending in 1997,  including Mr.
Kreh's award of 3,216 shares of  restricted  stock,  were  calculated  under the
award schedule established by the Committee based on these results.

     During  1997,  executive  officers  were  eligible  for  awards  under  the
Company's 1995 Stock Option Plan. Plan awards provide  executives with long-term
incentives and serve to further align executives' long-term interests with those
of  shareholders.  Stock  options  are  awarded  based upon the market  price of
Company  common  stock on the date of the grant and  provide a vehicle to reward
executives  only if the price of Company common stock  increases above the grant
price.

     Awards to be made to specific  participants are determined by the Committee
in its discretion.  The Company's outside  compensation  consultant reviews each
executive's  award in  comparison  to awards  made to  individuals  employed  by
companies  in  Comparison  Group I and makes  recommendations  as to whether the
awards made to Company  executives  should be  adjusted.  Several  factors  were
considered in determining the size of stock option grants to executive  officers
in 1997, including competitive practices at companies in Comparison Group I, the
Committee's  perception of the recipient's  ability to affect the results of the
Company  over time and  individual  levels  of  responsibility.  Awards  made to
executives in 1997,  including Mr.  Kreh's award of 75,000 stock  options,  were
determined by the Committee in its  discretion  based on its evaluation of these
criteria.

     The Committee and management have also agreed to the establishment of stock
ownership  guidelines for  executives.  Shares owned  directly or  beneficially,
restricted  shares and shares held in the  Company's  401(k) and employee  stock
ownership  plan  accounts  are counted for  purposes  of the  guidelines,  while
unexercised  stock options are not. Mr. Kreh's  ownership goal was set at 30,000
shares,  which he is expected to have achieved by the end of 1998.  The goal for
other  executives  is  ownership  of 6,000  shares  within  five  years of their
becoming an executive of the Company.  Three of the executives have reached this
goal and the others are expected to achieve it within the stated time frame.

     Under  Section  162(m)  of  the  Internal   Revenue  Code,   publicly  held
corporations  may not deduct  certain  types of  compensation  paid to the Chief
Executive Officer and the next four most highly  compensated  individuals to the
extent such compensation  exceeds $1 million.  Certain types of compensation are
excluded from this limitation,  including  performance-based  compensation  paid
under  plans that are  approved  by  shareholders  and  administered  by outside
directors.

Compensation  derived from the  exercise of stock  options  under the  Company's
plans and awards made under the current  provisions of the  Long-Term  Incentive
Plan are exempt from the limit on the corporate tax  deduction.  If the proposed
amendments to the Short-Term and Long-Term  Incentive Plan are approved,  awards
made pursuant to objective  formulas under those plans as amended will be exempt
from the  limit as  described  beginning  on page 17.  The  proposed  amendments
provide the Committee  with the ability to make  discretionary  awards which may

paid to  executives  during  1997 was fully  deductible.  For 1998,  the Company
anticipates that a portion of Mr. Kreh's  compensation will not be deductible as
a result of the award paid to him under the  Short-Term  Incentive  Plan in 1998
for superior performance in 1997.

(1)  For  1997,   represents  Long-Term  Incentive  Plan  awards  for  1995-1997
Performance  Period,  which were paid out in shares of  restricted  stock with a
five-year  vesting  period as  explained  in more detail in the Human  Resources
Committee  Report  on  Executive  Compensation  located  on page 8. The value of
restricted  stock shown in this column is calculated by multiplying  the closing
price of Company common stock on the date the restricted  shares were granted by
the number of shares  awarded.  Recipients are entitled to receive  dividends on
restricted stock to the extent paid on Company common stock generally. The total
number of  restricted  shares held on  12/31/97  by each of the named  executive
officers, and the aggregate value of such shares, calculated by multiplying them
by the closing  price of Company  common  stock on such date is as follows:  Mr.
Kreh, 2,666 shares,  $147,130  aggregate  value; Mr. Basch, 494 shares,  $27,263
aggregate value; Mr. Downs,  1,037 shares,  $57,229 aggregate value; Mr. Kelley,
1,086 shares,  $59,934  aggregate  value;  and Mr. Walker,  932 shares;  $51,435
aggregate value.

(2) The LTIP  payouts  column  shows  cash  payouts  made  under  the  Company's
Long-Term  Incentive Plan for the performance period that ended in 1995. Payouts
for the  performance  periods that ended in 1996 and 1997 were made in shares of
restricted stock, as reflected in the Restricted Stock Awards column.

(3)  For  1997,  reflects  Company  contributions  under  the  Company's  Thrift
Incentive Plan.

(4) Compensation for Mr. Basch reflects the fact that he was not employed by the
Company for a full year in 1995.

(1) Options granted are  nonstatutory  stock options.  The exercise price of the
option is equal to the fair market  value of the stock on the date of the grant.
Payment for the shares as to which an option is exercised may be made in cash or
in shares of Company  common  stock or a  combination  of cash and stock.  These
options may not be  exercised  any  earlier  than one year or any later than ten
years from the date of the grant.  Participants will be permitted to satisfy any
federal,  state or local tax requirements due upon exercise of a stock option by
delivering to the Company already-owned Company common stock or by directing the
Company  to  retain  stock   otherwise   issuable  upon  such  exercise  to  the
participant,  having a fair market value equal to the amount of the tax. Options
and stock  appreciation  rights will  generally be  nontransferrable  during the
lifetime of the participant,  except that the Human Resources  Committee may, in
its  discretion,  grant  nonqualified  stock  options  that  may be  transferred
pursuant to a qualified  domestic  relations  order,  or to an immediate  family
member or a trust for the benefit of an immediate family member.

(2) These figures are calculated pursuant to SEC rules by multiplying the number
of options  granted by the  difference  between the option  exercise price and a
future  hypothetical  stock price,  assuming  the value of Company  common stock
appreciates  5% or 10% each  year over the  original  option  price,  compounded
annually,  for the  life of the  options.  These  figures  are not  intended  to
forecast possible future appreciation, if any, of the Company's stock price.

</TABLE>


(1) This  table  reflects  the  schedule  of  awards  established  by the  Human
Resources Committee at the beginning of 1997 and represents the potential number
of  Performance  Contingent  Units that may be awarded to  participants  for the
1997-1999  Performance  Period  for the  indicated  levels  of  performance.  If
shareholders approve the amended Long-Term Incentive Plan as described beginning
on page 19,  participants  will forfeit any right to awards that would have been
determined in accordance with the foregoing schedule.  A detailed description of
the plan as in effect prior to  amendment  is  contained in the Human  Resources
Committee  Report on  Executive  Compensation  on page 8. The  actual  number of
performance units awarded at the end of a performance period, if any, is not yet
determinable  because the number of units earned is based on Company performance
during the  Performance  Period.  If the proposed  amended and restated  plan is
adopted,  the  revised  plan  will  be  implemented  with  two  shorter  initial
performance  periods as explained  beginning on page 19. The award schedules for
these periods had not yet been  determined as of the date of preparation of this
Proxy Statement,  but will be determined  within the time limit set forth in the
revised plan.

Both the current and revised plan provide that if  threshold,  target or maximum
goals are reached,  payouts of Performance Contingent Unit Awards under the plan
will be made in shares of Company common stock (which may be restricted  shares)
or  their  corresponding  cash  value  at  the  end  of  a  Performance  Period.
Performance  Contingent  Unit Awards are prorated for length of service during a
Performance Period, and for varying degrees of performance between the threshold
and maximum levels of  performance.  (For the  Performance  Period that ended on
December 31, 1997,  payouts were made in shares of restricted stock as indicated
in the Summary Compensation Table located on page 12).


Retirement Plans

The following table shows the estimated annual amounts payable on a life annuity
basis to a  participant  retiring  on  12/31/97  at age 65 under  the  Company's
qualified  defined benefit  pension plan based on  compensation  that is covered
under the plan and years of service  with the Company.  The table also  includes
amounts  payable  under  nonqualified  supplemental  pension  plans that provide
benefits  that  would  otherwise  be denied  participants  by reason of  certain
Internal  Revenue  Code  limitations  on  qualified  plan  benefits.  All of the
executives named in the Summary  Compensation  Table participate in these plans.
(A small portion of Mr. Kreh's annual retirement benefit shown in the table will
be paid from The Boiler Inspection and Insurance Company of Canada's  retirement
plan based on Mr. Kreh's initial service and earnings with that affiliate.)

Benefits payable under the Company's Retirement Plan are based on the average of
the  participant's  highest  three  consecutive  years of earnings in the 5-year
period before  retirement,  and on years of service.  Earnings covered under the
plan include  compensation  listed in the Summary  Compensation  Table under the
"Salary",  "Bonus",  "Restricted  Stock  Awards"  and  "LTIP  Payouts"  columns.
(Restricted  stock awarded  under the  Company's  stock option plans that vested
prior to December 31, 1996 is included in the  definition of earnings  under the
plan based on the stock's  value on the vesting date.  Restricted  stock awarded
under the Company's  Long-Term  Incentive Plan is included as earnings under the
plan in the year the shares are  awarded,  based on the fair market value of the
shares on the award date.) Credited years of service as of December 31, 1997 for
the individuals named in the Summary Compensation Table is as follows: Mr. Kreh,
27 years; Mr. Basch,  two years; Mr. Downs, 25 years; Mr. Kelley,  26 years; and
Mr. Walker, four years.

     In addition, the executive officers named in the Summary Compensation Table
are covered under a supplemental  retirement/death  benefit program.  Under this
program,  if the  executive  officer  should  die prior to his  retirement,  his
beneficiary  will be entitled  to an annual  death  benefit  equal to 50% of the
executive's  base salary for fifteen  years.  At  retirement,  the  executive is
entitled to an annual retirement  supplement equal to 35% of his base salary for
fifteen  years.  An  executive's  right to this  benefit  vests over a five-year
period, beginning on the date he is appointed an executive officer.

Employment Arrangements

     The  members  of the  Board  of  Directors  believe  that it is in the best
interests of the shareholders for the Company to have employment agreements with
each of the  executive  officers  named in the Summary  Compensation  Table (and
certain other key  employees)  to (i) encourage  them to remain in the Company's
employ during the uncertain  times which attend a threatened or actual change in
control of the  Company;  and (ii)  provide  specified  benefits in the event of
certain terminations  unrelated to a change in control event. Under the terms of
the agreements,  generally, a change in control shall be deemed to have occurred
if (i) any person acquires securities of the Company representing 25% or more of
the Company's  then  outstanding  securities;  (ii) current  directors and those
replacement or additional members of the Board  subsequently  approved by a vote
of at least two-thirds of the Board, cease to make up at least two-thirds of the
Board;  (iii) a merger or  consolidation  of the  Company  occurs  such that the
shareholders  of the  Company  prior to such  merger  own  less  than 60% of the
surviving  corporation;  or (iv) a complete  liquidation  or  dissolution of the
Company or disposition of all or substantially  all of the assets of the Company
occurs.  A threatened  change in control shall be deemed to have occurred if (i)
the Company enters an agreement,  which if consummated  would result in a change
in  control;  (ii) the  Company or any person  announces  an  intention  to take
actions which if  consummated  would  constitute a change in control;  (iii) any
person acquires securities of the

                                       15
<PAGE>

Company  representing 10% or more of the Company's then outstanding  securities;
or (iv) the Board determines that a threatened change in control has occurred.

     Upon a change in control, the following will occur: (i) under the Company's
Long-Term Incentive Plan, the fair market value of Performance  Contingent Units
allocated to the executive for each three-year  Performance  Period within which
the date of the change in control falls, prorated for actual service within each
Performance Period prior to such date, will be paid, and the restrictions on any
shares of restricted  stock awarded will lapse and any amounts  deferred will be
paid; (ii) under the Company's  Short-Term Incentive Plan, an award will be paid
calculated as though target  performance  was achieved for the year within which
the change in control  occurs;  and (iii) under the Company's Stock Option Plan,
all stock options  outstanding  on the date of the change in control will become
immediately  exercisable and the restrictions on any restricted stock previously
awarded will lapse.

     If an executive's employment with the Company is terminated within the term
of the agreement following a change in control or, under certain  circumstances,
a threatened change in control,  other than for cause or resignation (other than
for good reason, which means termination as a result of, among other things, the
involuntary  assignment  of such  executive  to  duties  inconsistent  with  the
executive's  position  prior to such  event or a  reduction  of the  executive's
current  compensation  or  benefits),  the  executive  becomes  entitled  to the
following:  (i) three times the sum of the executive's  base salary in effect at
the time of such event and the three-year  average of sums paid to the executive
under the Company's  Short-Term  and  Long-Term  Incentive  Plans;  (ii) a fully
vested  supplemental  retirement  benefit,  as described above under  Retirement
Plans; (iii) credit for an additional three years of service under the Company's
retirement plans; (iv) three years of welfare benefits provided at the Company's
then  current  subsidy  rate;  (v)  reimbursement  of any costs  incurred by the
executive  to enforce  the  agreement;  (vi)  outplacement  services;  and (vii)
payment to the executive  equal to the amount of any excise tax imposed upon the
executive  with respect to the foregoing  payments as a result of the occurrence
of such event.

     The agreements  also provide certain  severance  benefits in the event that
the Company  terminates the employment of the executive  other than for cause or
in connection  with a change in control.  In such event,  the executive would be
entitled  to receive  severance  payments in  installments  over a period of two
years equal to two times the executive's base salary,  outplacement services and
reimbursement of any costs incurred to enforce the agreement if the executive is
successful in such effort.

     The  Company  has  established  a  trust  (which  would  be  funded  upon a
threatened  change in control) pursuant to which payments under these agreements
and certain  other  benefit  plans will be paid in the event of a threatened  or
actual change in control.

                          TRANSACTIONS WITH MANAGEMENT

     Fleet  Financial  Group,  of  which  Mr.  Alvord  served  during  1997 as a
director,  performed  various services for the Company in 1997, among which were
acting as the trustee  for the  Company's  Retirement  Plan and  Employee  Stock
Ownership  Plan.  The Company and certain of its  subsidiaries  also  maintained
various  accounts with Fleet  Financial Group during 1997. In the opinion of the
Company,  the fees for these services were  comparable to those charged by other
financial  institutions.  The  Company  and its  subsidiaries  maintain  banking
relationships with various other financial institutions.

     The Company has  committed  to invest $2 million as a limited  partner in a
private  equity  limited  partnership  which  invests  principally  in  targeted
businesses  in the  financial  services  industry.  Mr. Alvord is a major equity
owner of the limited  liability  company which serves as the general  partner of
the partnership.

                                   PROPOSAL 2

           PROPOSAL TO AMEND AND RESTATE THE SHORT-TERM INCENTIVE PLAN

     The  Short-Term  Incentive  Plan  provides for annual  incentive  awards to
officers of the Company, including the executives,  provided certain performance
measures are achieved.  The plan is intended to provide an additional  incentive
for officers of the Company to make significant contributions to the performance
and

                                       17
<PAGE>

growth of the  Company,  and to attract  and retain in the employ of the Company
employees of exceptional ability.

     The Board of Directors has adopted,  subject to  shareholder  approval,  an
amended  Short-Term  Incentive Plan to be effective January 1, 1998. The revised
Short-Term  Incentive  Plan has been  designed  to qualify  certain  payments to
participants  under the plan as  performance-based  compensation  under  Section
162(m) of the Internal  Revenue Code. The plan has not been previously  approved
by shareholders.

     In the event that the revised Short-Term  Incentive Plan is not approved by
shareholders,  awards would  continue to be determined  in  accordance  with the
current  plan as in effect  prior to  amendment;  therefore,  a portion  of such
awards may not be  deductible  to the Company to the extent that (when  combined
with other non-exempt  compensation)  they exceed the limit set forth in Section
162(m) of the Internal Revenue Code.

     The  following  is a  summary  of the  material  features  of  the  amended
Short-Term  Incentive  Plan.  This  summary  is  qualified  in its  entirety  by
reference to the complete  text of the plan which has been filed  electronically
with the  Securities  and  Exchange  Commission  as an  appendix  to this  Proxy
Statement.  If approved by shareholders at the 1998 Annual Meeting,  the amended
Short-Term Incentive Plan will become effective as of January 1, 1998.

Administration

     The plan is administered by the Human Resources Committee of the Board (the
"Committee").  The  Committee  has  the  authority  to  designate  officers  and
employees  to  whom  awards  may be  granted  and to  determine  the  terms  and
conditions  of any  such  awards.  The  Committee  has the  authority  to  adopt
guidelines  for  carrying  out  the  plan  as it may  deem  appropriate,  and is
authorized to interpret the terms of the plan.

Eligibility

     All  officers  of the  Company  (other  than any  officer  who is the chief
executive  officer of any direct or indirect  subsidiary of the Company and is a
participant in the bonus plan of such  subsidiary,  or any individual  expressly
excluded by the  Committee)  are eligible under the plan. The Committee also has
the  authority  to  designate  certain  other key  employees  of the  Company as
participants  in the plan.  The  number of  individuals  currently  eligible  to
participate in the plan is twelve.

Plan Features

     Under the revised plan, at the beginning of each year,  the Committee  will
establish  target  awards based on the Company  achieving a certain level of Net
Income Per Share ("formula  awards").  Net income is defined as after-tax income
per share,  consolidating all subsidiaries,  inclusive of realized capital gains
and losses.  The  Committee  will have the  authority to exercise  discretion to
reduce (but not  increase)  the final  amount of any formula  awards to "covered
employees" (the executives  named in the  compensation  table) based on criteria
such as  individual  and  Company  performance.  Formula  awards made to covered
employees are designed to meet the  requirements  of Section  162(m) of the Code
regarding  performance-based  compensation.  The  Committee  will  also have the
ability to make discretionary  non-formula awards to participants under the plan
that  will not meet  Section  162(m)  requirements,  in order  for the  Board to
preserve  flexibility to reward  individuals for extraordinary  achievements not
contemplated  at the time a schedule was  established  for formula  awards.  The
actual award amounts that will be granted to specific  individuals in the future
is not presently determinable.

     For a formula award under the plan to be deductible  under Section  162(m),
the plan must include a dollar limit payable to a  participant  for a plan year.
The Board has set this limit at $2 million  for  formula  awards.  The limit for
formula  awards  under the  revised  plan has been set higher  than the level at
which awards have been made under the plan in the past,  and the Committee  does
not currently  expect to  significantly  increase the level of awards to be made
under the plan in the future.  The  significant  dollar limit and the  provision
permitting non-formula discretionary awards were included in the revised plan in
order to achieve tax  deductibility  for awards in most cases and still preserve
flexibility for the Board to reward achievements

                                       18
<PAGE>

related to non-recurring  extraordinary  events.  The plan as in effect prior to
amendment  contained a percentage of salary  limitation  but no specific  dollar
limitation.  The plan also provides that the Committee may require  deferral of,
or may  permit a  participant  to elect to defer,  all or part of an award.  The
deferral of an award until  retirement  could,  for example,  be required by the
Committee in order to enable such a payment to be tax  deductible by the Company
at the time it is paid out to a retired employee.  Payment of awards may be made
in the form of stock (which may be restricted), stock units or cash. The maximum
number  of  shares  of  common  stock  which  are  authorized  for  delivery  to
participants under the plan is 250,000.

Amendment of the Plan

     Under the terms of the plan,  the Committee is permitted to amend,  suspend
or discontinue  the plan subject to any  requirement  for  shareholder  approval
imposed by applicable law.

Shareholder Vote Required for Approval

     Approval of  Proposal 2 requires  that the number of votes cast in favor of
the proposal exceed the number of votes cast opposing the proposal. The Board of
Directors unanimously recommends a vote FOR Proposal 2.



                                   PROPOSAL 3

           PROPOSAL TO AMEND AND RESTATE THE LONG-TERM INCENTIVE PLAN

     The current Long-Term  Incentive Plan was approved by shareholders on April
18, 1995 and is scheduled  to expire on December  31,  1998.  The purpose of the
plan is to provide  incentives  for  executives  of the Company to increase  the
earnings  of the  Company on a  long-term  basis;  to attract  and retain in the
employ of the Company individuals of outstanding abilities;  and to more closely
align the interests of executives with shareholders of the Company. The plan has
been  designed to qualify  certain  payments to  participants  under the plan as
performance-based  compensation  under  Section  162(m) of the Internal  Revenue
Code.

     The Board of  Directors  of the  Company  adopted,  subject to  shareholder
approval,  several amendments to the plan,  including the following  significant
changes,  to be effective  January 1, 1998: an extension of the term of the plan
to December 31, 2003; an increase in the number of shares available for delivery
to participants thereunder to 250,000; an increase in the maximum amount payable
to a participant with respect to Performance Contingent Awards for a Performance
Period  to $2  million;  a  provision  for the  Committee  to  make  non-formula
discretionary awards; and a modification to the Performance Period definition to
permit the  Committee  to set  Performance  Periods of three years or such other
period as the Committee may determine. Based on significant transactions entered
into by the Company during 1997 including changes to its capital  structure,  as
discussed in the 1997 Annual Report,  the Board  determined  that the previously
established  schedules for  Performance  Periods ending in 1998 and 1999 were no
longer relevant or appropriate.  As a result, if the plan as amended is approved
by  shareholders  at the 1998 Annual  Meeting,  executives will waive any rights
under the previous award schedules and the revised plan will be implemented with
two shorter initial Performance Periods which will end in 1998 and 1999.

     By approving the amended  Long-Term  Incentive Plan,  shareholders  will be
approving,   among  other  things,   the   performance   measures,   eligibility
requirements   and  limits  on  certain  awards  contained   therein,   and  the
authorization of an additional 100,000 shares of common stock of the Company for
delivery to participants under the plan. In the event that the revised Long-Term
Incentive Plan is not approved by  shareholders,  tax-deductible  formula awards
would continue to be determined in accordance with the current plan as in effect
prior  to   amendment   and  the  Board  would   consider   making   potentially
non-deductible awards in recognition of the Company changes referred to above.

     The  following  is a summary  of the  material  features  of the  Long-Term
Incentive  Plan,  as  amended.  This  summary is  qualified  in its  entirety by
reference to the complete  text of the plan which has been filed  electronically
with the  Securities  and  Exchange  Commission  as an  appendix  to this  Proxy

Administration

     The plan is administered by the Human Resources Committee of the Board (the
"Committee").  The  Committee  has  the  authority  to  designate  officers  and
employees  to  whom  awards  may be  granted  and to  determine  the  terms  and
conditions  of any  such  awards.  The  Committee  has the  authority  to  adopt
guidelines  for  carrying  out  the  plan  as it may  deem  appropriate,  and is
authorized to interpret the terms of the plan.

Eligibility

     All Senior  Officers of the Company  (presently  defined as Chief Executive
Officer, President,  Executive Vice President, Senior Vice President,  Corporate
Secretary and Treasurer),  other than any individual  expressly  excluded by the
Committee,  are eligible under the plan. The Committee also has the authority to
designate certain other officers or key employees of the Company as participants
in the plan. The number of individuals  currently eligible to participate in the
plan is seven.

Plan Features

     Performance  Periods  are  defined as periods  of three  consecutive  years
beginning  each  January 1 or such other  period as the  Committee  may specify.
Prior to or within ninety days following the  commencement  of each  Performance
Period,  the Committee shall establish in writing,  for each participant (or for
all  participants  as  a  group),   specific  objective  Performance  Goals  for
Performance  Contingent Awards based on one or more of the following Performance
Measures: combined ratio; expense ratio; net income per share; return on equity;
total shareholder return; return on assets; revenues; operating margin; increase
in book value; and market share. For each Performance Goal, an award schedule of
Performance  Contingent  Units is  established  for minimum,  target and maximum
attainment of such goal,  based on a percentage of a  participant's  base salary
rate (adjusted for any  promotional  increases  during the  Performance  Period)
divided by the  average  of the high and low  trading  prices of Company  common
stock  on  the  first  trading  date  of  the  Performance  Period.  Performance
Contingent  Units are defined as the right to receive up to 100% of the value of
shares of common stock of the  Company,  which value may be paid in share units,
shares (including  restricted  shares) of common stock of the Company or cash as
determined by the Committee.

     The actual  Performance  Contingent Award to be paid to a participant under
the schedule  described above at the conclusion of the Performance  Period shall
be based on the level of attainment of the  Performance  Goals  established  for
such period.  Performance  Contingent  Awards are prorated for actual  length of
service  during  the  Performance  Period.  Following  the end of a  Performance
Period,  the Committee  shall  ascertain and certify in writing  whether and the
degree  to which  the  Performance  Goals for such  period  have  been met.  Any
payments shall be made in cash, in share units or shares of Company common stock
(which may either be restricted or not), as determined by the Committee.  At the
discretion of the  Committee,  dividend  equivalents  may be paid in conjunction
with payouts  made under the plan,  equal to the amount of cash  dividends  that
would have been paid during the  Performance  Period with respect to an award of
Performance Contingent Units if the award had been made in Company common stock.
The Committee shall have the authority to reduce  Performance  Contingent Awards
otherwise  payable to participants  but shall not have the authority to increase
any  Performance  Contingent  Award  calculated  under  the  terms of the  award
schedule.  Performance Contingent Awards made pursuant to the schedule described
above are designed to meet the  requirements  of Section  162(m) of the Internal
Revenue Code regarding performance-based  compensation.  The Committee will also
have the ability to make  discretionary  awards to  participants  under the plan
that will not meet Section 162(m) requirements, as the Board has determined that
it is in the best  interests  of the Company to preserve  flexibility  to reward
executives for achievements  related to extraordinary events not contemplated at
the time the schedule is established  for  Performance  Contingent  Awards.  The
actual  amounts that will be granted under the plan to specific  individuals  in
the future is not presently determinable.

     For a Performance  Contingent  Award under the plan to be deductible  under
Section  162(m),  the plan must include a dollar limit  payable to a participant
for a plan  year.  The Board has set this limit at $2  million  for  Performance
Contingent Awards. The limit for Performance Contingent Awards under the revised
plan

                                       20
<PAGE>

has been set higher than the level at which awards have been made under the plan
in the past,  and the  Committee  does not  currently  expect  to  significantly
increase the level of awards to be made under the plan in the future.  The limit
was   increased  to  $2  million  and  the  provision   permitting   non-formula
discretionary  awards was  included in the revised  plan in order to achieve tax
deductibility  for awards in most cases and still preserve  flexibility  for the
Board to reward achievements related to non-recurring  extraordinary events. The
plan also provides  that the Committee may require  deferral of, or may permit a
participant to elect to defer, all or part of an award. The deferral of an award
until retirement could, for example,  be required by the Committee,  in order to
enable such a payment to be tax deductible by the Company at the time it is paid
out to a retired employee.

Amendment of the Plan

     Under the terms of the plan,  the Committee is permitted to amend,  suspend
or discontinue  the plan subject to any  requirement  for  shareholder  approval
imposed by applicable law.

Shareholder Vote Required for Approval

     Approval of  Proposal 3 requires  that the number of votes cast in favor of

and an "outside  director" within the meaning of Section 162(m) of the Code. The

carrying  out the  Plan as it may deem  appropriate.  Such  guidelines  shall be
consistent  with the Plan and may include,  but need not be limited to, the size

Decisions  of the  Committee  shall be final,  conclusive  and binding  upon all

4.   Eligibility for Awards

Any employee who is an Officer of the Company (other than any Officer who is the

provided in Section 6. The Committee may in its discretion  designate  other key
employees to  participate  in the Plan.  Eligibility  will be  determined at the
close of each Plan Year.


5.   Basis of Awards

At the beginning of each Plan Year, the Committee shall establish  Target Awards
and the level of Net Income  which must be achieved for a Plan Year in order for
Target Awards to be payable to Participants.  The maximum amount of any Award to
be paid to a Participant under the Plan is $2,000,000.  The Committee shall have
the sole authority to determine the amount of any Award within the above maximum
for each  Participant.  In determining  such Award, the Committee shall consider
the contribution made by the Participant  towards  achievement of the Net Income
and such other factors as the Committee considers appropriate.


6.   Awards to Covered Employees

     a)   If the  Committee  determines  at the  time  that a  Target  Award  is
          established for a Participant  that such  Participant is, or may be as
          of the end of the tax year for which  the  Company  would  claim a tax
          deduction for such Award, a Covered  Employee,  then the Committee may
          provide  that this  Section 6 is  applicable  to such Award under such
          terms as the Committee shall determine.

     b)   If an award is subject to this Section 6, then the level of Net Income
          which  must be  achieved  for a Plan Year will be  established  by the
          Committee  within  90 days of the  beginning  of a Plan Year or within
          such other time period set forth under  Section  162(m) of the Code or
          any  regulations  thereunder  in order for such level to be considered
          "pre-established".

     c)   The  Committee  may, in its  discretion  reduce the Award payable to a
          Covered  Employee at any time prior to payment  based on such criteria
          it may  establish.  Notwithstanding  any provision in this Plan to the
          contrary,  the  Committee  may not adjust  upwards the amount  payable
          pursuant to any award  subject to this Section 6, nor may it waive the
          achievement of Net Income pre-established by the Committee pursuant to
          this Section 6 except in the case of a Participant  who no longer is a
          Covered Employee at the time such award is paid.

     d)   Prior to the  payment of any Award to a Covered  Employee  pursuant to
          this Section 6, the  Committee  shall  certify in writing that the Net
          Income level applicable to such Award has been met.

     e)   The Committee  shall have the power to impose such other  restrictions
          on  awards  subject  to this  Section  6 as it may deem  necessary  or
          appropriate  to ensure that such Awards satisfy all  requirements  for
          "performance-based  compensation" within the meaning of section 162(m)
          of the Code, and any regulations thereunder.


7.   Timing and Form of Payment of Awards

The Committee will have the sole  discretion to determine the form of payment of
an Award for each Participant. Awards may be payable in cash or in the form of a
Stock Grant,  or a  combination  of the  foregoing  and shall be subject to such
other conditions and restrictions as the Committee shall establish.


8.   Deferral of Payment

     a)   A  Participant  may, with  permission of the Committee  elect to defer
          receipt  of all or a  specified  part of any Award.  Such an  election
          shall be subject to such terms and conditions as are prescribed by the
          Committee.  Deferral elections are irrevocable and must be made during
          the time period and in the manner prescribed by the Committee.

     b)   To the extent that the Committee,  in its discretion,  determines that
          the  payment  of an  Award  would  not be  deductible  by the  Company
          pursuant  to  Section  162(m) of the  Code,  the  Committee  may defer
          payment of all or the non-deductible  portion of such Award until such
          time as such amount would be  deductible.  The terms and conditions of
          any such deferral shall be prescribed by the Committee.

     c)   The right of a Participant to receive any unpaid portion of any amount
          deferred  hereunder  shall be an unsecured  claim  against the general
          assets of the Company.


9.   Tax Withholding

The Company shall have the right to require Participants to remit to the Company
an amount  sufficient to satisfy any tax  withholding  requirements or to deduct
from any payments  made  pursuant to the Plan amounts  sufficient to satisfy tax
withholding requirements.


10.  No Right to an Award or Continued Employment

     a)   Nothing  contained in this Plan or in any resolution  adopted or to be
          adopted by the Board of Directors  will  constitute the granting of an
          Award  hereunder.  The granting of an Award  pursuant to the Plan will
          take  place only when  authorized  by the  Committee.  No Award and no
          rights of ownership  thereunder  will be  transferable  otherwise than
          pursuant  to  Section  12.  There  is no  obligation  imposed  on  the
          Committee for uniformity of treatment of Participants under the Plan.

     b)   Nothing in the Plan shall interfere with or limit in any way the right
          of the Company to terminate any Participant's  employment at any time,
          nor confer upon any Participant any right to continue in the employ of
          the Company.

11.  Rights on Termination of Employment

     a)   If a  Participant  in this Plan shall  terminate  employment  with the
          Company on account of death,  Retirement  or  Disability  or otherwise
          terminates  employment with the written consent of the Committee prior
          to the end of any Plan Year in respect of which such  Participant  may
          be eligible for an Award,  the amount of the award, if any, payable to
          the  Participant  or his or her  beneficiary,  shall be prorated based
          upon the number of full and partial  months of employment  within such
          Plan Year.

     b)   A Participant whose employment terminates by dismissal with or without
          cause,  or who  voluntarily  terminates his or her employment  without
          consent prior to the  expiration of a Plan Year,  will not be entitled
          to receive an award under the Plan.  Notwithstanding the foregoing,  a
          Participant  whose employment  terminates within two years following a
          Change  in  Control  and  prior to the end of any Plan  Year  shall be
          entitled to receive an Award as though such  termination  was with the

          has been deferred pursuant to Section 8 be subject to forfeiture.


12.  Designation of Beneficiary

A Participant may file with the Corporate Secretary of the Company a designation
of a beneficiary or beneficiaries on the appropriate form, which designation may
be changed or revoked by the Participant's sole action, provided that the change
or revocation is filed with the Corporate Secretary. In case of the death of the
Participant, before or after termination of employment, any Award to which he or
she is entitled  and any  deferred  portions of a deceased  Participant's  Award
shall be delivered to the beneficiary or  beneficiaries  so designated or, if no
beneficiary has been designated or survives such Participant,  will be delivered
to, or in accordance  with the directions of, the executor or  administrator  of
such Participant's estate.


13.  Change in Control

     a)   In the event of a Change in  Control of the  Company,  this Plan shall
          continue to be binding upon the Company,  any successor in interest to
          the Company and all persons in control of the Company or any successor
          thereto and no  transaction or series of  transactions  shall have the
          effect of reducing or canceling  the Award of a  Participant  that has
          been  declared  but not paid  unless  consented  to in writing by such
          affected Participant.

     b)   As soon as  practicable  following a Change in Control,  a Participant
          shall be paid a lump sum  amount  in cash  equal to the  Target  Award
          payable  to the  Participant  (in  lieu  of any  other  award  payable
          hereunder for the Plan Year within which the Change in Control occurs)
          and any  Awards  previously  deferred  in  accordance  with  Section 8
          hereof, plus interest accrued thereon up until the date of payment.

     c)   Upon a Change in Control the restrictions and deferral limitations and
          other  conditions  applicable  to any Stock  Grant  made  pursuant  to
          Section 7 shall lapse as of the date of such Change in Control.


14.  Unfunded Obligations; Trust Agreement

     a)   The  Company  will pay from its  general  assets all awards to be made
          hereunder.  However,  the  Company may in its  discretion  establish a
          trust,  escrow  agreement or similar  arrangement  in order to aid the
          Company in meeting its obligations hereunder.

     b)   Any assets  transferred by the Company into any such arrangement shall
          remain at all times assets of the Company and subject to the claims of
          the  Company's  general  creditors  in  the  event  of  bankruptcy  or
          insolvency of the Company.  No security  interest in such assets shall
          be created in a Participant's  favor and a Participant's  rights under
          this Plan and under any such  arrangement  shall be those of a general
          unsecured creditor of the Company.


15.  Assignment and Alienation

Benefits under this Plan may not be anticipated,  assigned  (either at law or in
equity), alienated, or subjected to attachment,  garnishment, levy, execution or
other legal or equitable  process.  If any Participant or beneficiary under this
Plan  becomes  bankrupt or attempts to  anticipate,  alienate,  sell,  transfer,
assign,  pledge,  encumber or charge any benefit  under this Plan,  such benefit
shall, in the discretion of the Committee,  cease and terminate,  in which event
the  Committee may hold or apply the same or any part thereof for the benefit of
such Participant, his or her beneficiary,  spouse, children, other dependents or
any of such individuals, in such proportion as the Committee may deem proper.


16.  Modification or Termination of the Plan

     a)   The Committee may at any time terminate or from time to time modify or
          suspend, and if suspended,  may reinstate any or all of the provisions
          of this Plan,  subject to any  requirement  for  shareholder  approval
          imposed by applicable  law,  except that no  modification of this Plan
          may be made which will adversely affect any rights or obligations with
          respect to any awards theretofore made under the Plan.

     b)   The  Corporate  Secretary of the Company  shall be  authorized to make
          minor or administrative  changes in the Plan or changes required by or
          made desirable by law or government regulation.


17.  Other Plans and Special Awards

     a)   Nothing  contained in this Plan shall  prohibit  the  Committee or the
          Board from  granting  other  awards or  establishing  other  incentive
          compensation plans providing for the payment of incentive compensation
          to employees, including Participants.

     b)   Notwithstanding  Section  6 and  the  intention  of the  Committee  to
          maintain  tax  deductibility  of awards  granted  hereunder to Covered
          Employees  pursuant  to  Section  162(m)  of the Code,  the  Committee
          reserves the right to grant awards which do not meet the  requirements
          of Section 162(m) as to  deductibility  (for example,  awards based on
          measures  other  than Net  Income  or  otherwise  not  established  in
          accordance  with  Section  6 ) in  order  to  recognize  unanticipated
          business  conditions  or events which have, or are expected to have, a
          significant effect on the Company.



18.  Shares Subject to the Plan

     a)   Subject to Section 18 ( b), the  maximum  number of Shares that may be
          delivered to Participants and their beneficiaries under the Plan shall
          be 250,000. Any Shares covered by a Stock Grant which are subsequently
          forfeited,  withheld to cover tax withholding or settled in cash shall
          be deemed to have not been delivered for purposes of  determining  the
          maximum number of Shares available for delivery under the Plan.

     b)   In the event of any change in the  Shares of the  Company by reason of
          any stock  dividend,  stock split,  recapitalization,  reorganization,
          merger, consolidation,  split-up,  combination, or exchange of shares,
          or rights offering to purchase Shares at a price  substantially  below
          Fair Market Value, or of any similar change affecting the Shares,  the
          number  of  Shares  covered  by a Stock  Grant  which  have  not  been
          delivered,  and the number of Shares which may be delivered hereunder,
          shall be  appropriately  adjusted  consistent with such change in such
          manner as the Board in its  discretion  may deem  equitable to prevent
          substantial  dilution or  enlargement of the awards and rights granted
          or made available to  Participants  hereunder.  Any fractional  Shares
          resulting from such adjustments shall be eliminated.


19.  Effective Date

This Plan as amended  and  restated  shall be  effective  as of January 1, 1998,
subject to approval by  shareholders  at their annual meeting in 1998, and shall
remain in effect until such time as it shall be terminated by the Committee.

          such terms and conditions as are prescribed by the Committee. Deferral
          elections are  irrevocable and must be made during the time period and
          in the manner prescribed by the Committee.

     (b)  To the extent that the Committee,  in its discretion,  determines that
          the payment of a Performance  Contingent Award would not be deductible
          by the Company  pursuant to Section  162(m) of the Code, the Committee
          may defer payment of all or the  non-deductible  portion of such award
          until  such time as such  amount  would be  deductible.  The terms and
          conditions of any such deferral shall be prescribed by the Committee.

     (c)  The right of a Participant to receive any unpaid portion of any amount
          deferred  hereunder  shall be an unsecured  claim  against the general
          assets of the Company.

9.   Adjustments in the Event of Change in Common Stock of the Company

     In the event of any  change in the  Shares of the  Company by reason of any
     stock  dividend,  stock split,  recapitalization,  reorganization,  merger,
     consolidation,  split-up,  combination,  or exchange  of shares,  or rights
     offering  to  purchase  Shares at a price  substantially  below Fair Market
     Value,  or of any  similar  change  affecting  the  Shares,  the  number of
     Performance  Contingent  Units  awarded  which  have not been  paid and the
     number of Shares  covered by a Stock Grant  which have not been  delivered,
     and the  number  of  Shares  which  may be  delivered  hereunder,  shall be
     appropriately  adjusted  consistent  with such change in such manner as the
     Board in its discretion may deem equitable to prevent substantial  dilution
     or  enlargement  of the awards  and rights  granted  to, or  available  for
     Participants   hereunder.   Any  fractional   shares  resulting  from  such
     adjustments shall be eliminated.

10.  No Right to an Award or Continued Employment

     (a)  Nothing  contained in this Plan or in any resolution  adopted or to be
          adopted by the Board of Directors  will  constitute the granting of an
          award  hereunder.  The granting of an award  pursuant to the Plan will
          take  place only when  authorized  by the  Committee.  No award and no
          rights of ownership  thereunder  will be  transferable  otherwise than
          pursuant  to  Section  12.  There  is no  obligation  imposed  on  the
          Committee for uniformity of treatment of Participants under the Plan.

     (b)  Nothing in the Plan shall interfere with or limit in any way the right
          of the Company to terminate any Participant's  employment at any time,
          nor confer upon any Participant any right to continue in the employ of
          the Company.

11.  Rights on Termination of Employment

     (a)  If a  Participant  in this Plan shall  terminate  employment  with the
          Company on account of Retirement or Disability or otherwise  terminate
          employment  with  the  written  consent  of the  Company  prior to the
          expiration  of any  Performance  Period(s)  in  respect  of which such
          Participant  may be eligible for an award, or if a subsidiary at which
          a  Participant  is  employed  shall  cease to be a  subsidiary  of the
          Company prior to the  expiration  of any  Performance  Period(s),  the
          award(s) paid to such Participant  shall be prorated  according to the
          number of months of employment in each such Performance Period.

     (b)  A Participant whose employment terminates by dismissal with or without
          cause, or who voluntarily  terminates employment without consent prior
          to the  expiration  of a Performance  Period,  shall lose any right to
          receive payment of such award.


     (c)  In no event  shall an award or a portion  thereof the payment of which
          has been deferred pursuant to Section 8 be subject to forfeiture.

12.  Death of a Participant

     (a)  A Participant  may file with the Corporate  Secretary of the Company a
          designation of a beneficiary or beneficiaries on the appropriate form,
          which designation may be changed or revoked by the Participant's  sole
          action,  provided  that the  change or  revocation  is filed  with the
          Corporate Secretary.  In case of the death of the Participant,  before
          or after  termination of employment,  any earned but unpaid portion of
          an award to which he or she is entitled and any deferred portions of a
          deceased  Participant's award shall be delivered to the beneficiary or
          beneficiaries  so designated or, if no beneficiary has been designated
          or survives such Participant,  shall be delivered to, or in accordance
          with  the  directions  of,  the  executor  or  administrator  of  such
          Participant's estate.

     (b)  If  a  Participant  shall  die  during  a  Performance   Period,  such
          Participant's  beneficiary shall only be entitled to receive the award
          declared  for  the  Performance  Period  ending  in  the  year  of the
          Participant's death.

13.  Tax Withholding

     The Company  shall have the right to require  Participants  to remit to the
     Company an amount sufficient to satisfy any tax withholding requirements or
     to deduct from any payments made pursuant to the Plan amounts sufficient to
     satisfy tax withholding requirements.

14.  Modification or Termination

     (a)  The Committee may at any time terminate or from time to time modify or
          suspend, and if suspended,  may reinstate any or all of the provisions
          of this Plan,  subject to any  requirement  for  shareholder  approval
          imposed by applicable  law,  except that no  modification of this Plan
          may be made which will adversely affect any rights or obligations with
          respect to any awards theretofore made under the Plan.

     (b)  The  Corporate  Secretary of the Company  shall be  authorized to make
          minor or administrative  changes in the Plan or changes required by or
          made desirable by law or government regulation.


15.  Change in Control

     (a)  In the event of a Change in  Control of the  Company,  this Plan shall
          continue to be binding upon the Company,  any successor in interest to
          the Company and all persons in control of the Company or any successor
          thereto,  and no transaction or series of transactions  shall have the
          effect of reducing or canceling  the award of a  Participant  that has
          been  declared  but not paid  unless  consented  to in writing by such
          affected Participant.

     (b)  As soon as  practicable  following a Change in Control,  a Participant
          shall be paid a lump sum amount in cash equal to the  aggregate  value
          of the  Performance  Contingent  Awards payable to the Participant for
          each of the Performance Periods within which the date of the Change in
          Control  occurs,  calculated  as to each  such  Performance  Period by
          multiplying  the award that the  Participant  would have earned on the
          last day of such Performance Period,  assuming the achievement of each
          of the  Performance  Goals at the target  level  established  for such
          Performance Period, by the fraction obtained by dividing the number of
          full  months  and  any  fractional  portion  of a  month  during  such
          Performance  Period prior to the Change in Control by the total number
          of months  contained in such Performance  Period.  For purposes of the
          preceding  sentence,  the amount of cash  delivered  in payment of the
          value of the Performance  Contingent  Awards shall equal the number of
          Performance   Contingent  Units  constituting  such  each  such  award
          multiplied  by the  greater of (i) the highest  Fair Market  Value per
          share of Stock at any time  during the  60-day  period  preceding  the
          Change in Control and (ii) if  applicable,  the price of a Share which
          is paid or offered to be paid, by any person or entity,  in connection
          with the transaction  constituting  the Change in Control.  The amount
          paid hereunder shall be in lieu of any other awards payable under this
          Plan for the  Performance  Periods  within which the Change in Control
          occurs.

     (c)  Upon a Change in Control,  the restrictions  and deferral  limitations
          applicable  to any Stock  Grant made  pursuant  to Section 7 hereunder
          shall lapse as of the date of such Change in Control.

     (d)  As soon as  practicable  following a Change in Control,  any awards or
          Dividend Equivalents  previously deferred in accordance with Section 8
          hereof,  plus interest  accrued  thereon up until the date of payment,
          shall be paid in full.

16.  Other Plans and Special Awards

     (a)  Nothing  contained in this Plan shall  prohibit  the  Committee or the
          Board from  granting  other  awards or  establishing  other  incentive
          compensation plans providing for the payment of incentive compensation
          to employees, including Participants.

     (b)  Notwithstanding  Section  6 and  the  intention  of the  Committee  to
          maintain tax  deductibility  of awards granted  hereunder  pursuant to
          Section 162(m) of the Code, the Committee  reserves the right to grant
          awards  which do not meet the  requirements  of  Section  162(m) as to
          deductibility  (for  example,  awards  based on  measures  other  than
          Performance Measures or not established in accordance with Section 6 )
          in order to  recognize  unanticipated  business  conditions  or events
          which have,  or are  expected  to have,  a  significant  effect on the
          Company.

17.  Unfunded Obligations; Trust Agreement

     (a)  The  Company  will pay from its  general  assets all awards to be made
          hereunder.  However,  the Company may in its  discretion,  establish a
          trust,  escrow  agreement or similar  arrangement  in order to aid the
          Company in meeting its obligations hereunder.

     (b)  Any assets  transferred by the Company into any such arrangement shall
          remain at all times assets of the Company and subject to the claims of
          the  Company's  general  creditors  in  the  event  of  bankruptcy  or
          insolvency of the Company.  No security  interest in such assets shall
          be created in a Participant's  favor and a Participant's  rights under
          this Plan and under any such  arrangement  shall be those of a general
          unsecured creditor of the Company.

18.  Assignment and Alienation

     Benefits under this Plan may not be anticipated, assigned (either at law or
     in equity),  alienated,  or subjected  to  attachment,  garnishment,  levy,
     execution  or other  legal or  equitable  process.  If any  Participant  or
     beneficiary  under this Plan  becomes  bankrupt or attempts to  anticipate,
     alienate,  sell, transfer,  assign, pledge,  encumber or charge any benefit
     under this Plan,  such benefit  shall,  in the discretion of the Committee,
     cease and  terminate,  in which event the  Committee  may hold or apply the
     same or any part  thereof for the benefit of such  Participant,  his or her
     beneficiary, spouse, children, other dependents or any of such individuals,
     in such manner and in such proportion as the Committee may deem proper.

19.  Effective Date and Termination of the Plan

     This Plan, as amended, shall become effective as of January 1, 1998 subject
     to the approval of the shareholders at their annual meeting in 1998. Unless
     earlier  terminated by the Committee  subject to Section 14, the Plan shall
     terminate on December 31, 2003. No  Performance  Contingent  Award shall be
     made  pursuant  to this Plan after the  termination  date,  but awards made
     prior to its termination date may extend beyond that date.

To:  All Employees

From:  R. K. Price, Senior Vice President and Corporate Secretary

Date:  March 16, 1998


If you are a participant in any of the Company's stock plans (Payroll Investment
Plan, Employee Stock Ownership Plan, Thrift Incentive Plan - HSB Stock Fund, the
Long-Term  Incentive  Plan or the Stock Option and Restricted  Stock Plan),  you
should  receive proxy  materials  for this year's  Annual  Meeting to be held on
April 21, 1998 through the U.S. mail shortly.

Annual reports and proxy materials were  distributed  beginning on March 6, 1998
via bulk mail in order to save on postage expenses. As many of you know, HSB has
used bulk mail for several years for this reason,  and, although cost effective,
it can result in some delays in delivery.

If you hold shares registered other than in your name alone (e.g.,  jointly with
another  individual  or as  custodian  for a minor's  account)  you may  receive
additional  copies of the  materials.  You are  encouraged  to return any excess
copies of the  Annual  Report to your  department  or Branch  Office,  and extra
copies of the proxy statement to Jean Cohn, Law Department, Home Office.

Included with the proxy  materials is a card upon which to register your vote in
connection with actions  proposed to be taken at the Annual  Meeting.  The proxy
card  lists the number of shares  allocated  to your  account  under each of the
plans in which you  participate,  as well as any shares you hold  directly.  The
following abbreviations are used to identify your holdings:

COM - Shares held directly or through the Payroll Investment Plan

RST - Restricted Stock held in the Company's plans

TIP - Shares  allocated to your account under the Thrift  Incentive  Plan if you
participate in the HSB Stock Fund

ESO - Shares  allocated to your account under the Employee Stock  Ownership Plan
(ESOP)

Whether you own one share or a thousand,  it is very  important that your shares
be represented at the Annual Meeting.  As a shareholder,  you have the right and
an obligation to have your vote count at the Annual Meeting.  I encourage you to
use this  opportunity  by  completing  the proxy card and sending it back in the
envelope provided.

If you do not receive your  materials by April 10, 1998, or if you misplace your
card, please contact Jean Cohn, Home Office, Ext. 5724.
