right to vote  should you attend the meeting and the proxy may be revoked at any
time before it is voted.  Properly executed proxies not revoked will be voted as
specified.

     Arrangements  will  be made  with  brokers,  nominees  and  fiduciaries  to
distribute  proxy material to their  principals,  and their postage and clerical
expenses in so doing will be paid by the Company.  The entire cost of soliciting
proxies  on  behalf  of  management  will be  borne by the  Company.  Directors,

shares  represented  for  matters  to be voted  upon at the  meeting  for quorum
purposes.  Abstentions and broker non-votes will not be counted as either FOR or

directors,  the approval of the Stock Option Plan amendment or the  ratification
of auditors.

James Ferland and Wilson Wilde. 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.

Meetings and Remuneration of the Directors

        During  1996,  the Board of Directors  held ten meetings and  twenty-two
committee  meetings.  Each director attended at least 75% of the meetings of the
Board and committees on which he or she served combined.


     The annual retainer in effect during 1996 for each director who was neither
a present or retired employee of the Company nor of a subsidiary was $25,000. In
1996, under the 1989 Restricted Stock Plan for Non-Employee Directors,  one-half
of the annual retainer was paid in restricted  stock of the Company and one-half
was  paid in  cash.  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  herein 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.

        In 1996,  the  Governance  Committee of the Board of Directors  reviewed
compensation  policies currently in place for non-employee  members of the Board
of Directors  and adopted a formal policy for the  compensation  of directors in
order to further link  director  compensation  with the  long-term  interests of
stockholders.  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
stockholders  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.


        In  connection  with the adoption of the director  compensation  policy,
several changes were made to the director compensation program in 1996. The 1989
Restricted  Stock  Plan for  Non-Employee  Directors  was  terminated  effective
September 23, 1996. The annual retainer was reduced  effective  January 1, 1997,
from $25,000 to $15,000 and the Directors Stock and Deferred  Compensation  Plan
(the "Directors  Plan"),  described below, was adopted  effective  September 23,
1996. The Retirement Plan for non-employee  directors was terminated for current
and future  directors  effective  September 23, 1996.  Former  directors who had
retired  from the Board prior to  September  23,  1996 will  continue to receive
benefits under the Retirement  Plan.  Under the terms of the Retirement  Plan as
formerly in effect,  a director  who  retired  after ten years of service on the
Board was entitled to receive an annual lifetime retirement benefit equal to the
annual  retainer  paid to such director  immediately  prior to  retirement.  All
current  directors  waived any right to receive  retirement  benefits  under the
Retirement  Plan,  and the  value of such  benefits  was  converted  into  stock
equivalent  units under the Directors  Plan.  In addition,  shares of restricted
stock  previously  awarded to directors under the 1989 Restricted Stock Plan for
Non-employee Directors as to which an election for current taxation had not been
made were canceled,  and an equal number of stock  equivalent units was awarded.
In the case of  restricted  shares as to which an election for current  taxation
had been made, the restrictions on such shares were canceled.

        Under the Directors Plan, each non-employee  director receives an annual
award of 550 stock equivalent  units, and may elect to defer all or a portion of
his or her cash compensation (annual retainer and meeting fees) for payment to a
future date  specified by the director.  A  participating  director may elect to
have his or her deferred account either 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 translated  into
stock  equivalent  units.  The number of stock  equivalent units is equal to the
amount of cash  compensation  divided by the fair market value of Company common
stock on the date such compensation would otherwise have been paid.

        Account  balances held under the Directors  Plan are paid out in cash or
an equivalent  number of shares of Company common stock,  at the election of the
director.  Amounts may be paid out either in a lump sum or in  installments,  at
the directors' election.  Dividend equivalents, in an amount equal to the amount
of  dividends  that  would have been  payable  had each  stock  equivalent  unit
constituted a share of Company  common stock,  are payable in cash at the end of
each plan year on all stock equivalent units credited under the plan.

        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 quarterly and annual  financial
statements.  The Audit  Committee  held four meetings  during 1996.  Mr. Ferland
(Chairman),  Mr. Booth, Mr. Powers 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 9. 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'  Retirement  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  1996.  Mr.  Ellis
(Chairman),  Mr. Campbell, Mr. Powers 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 stockholder must have been made by proper
written notice given to the Corporate Secretary not later than February 15, 1997
in order to be considered for the 1997 Annual Meeting.  The Governance Committee
held seven  meetings  during 1996. 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 five meetings
in 1996. 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 1996.

Section 16(a) Beneficial Ownership Reporting Compliance

        Ownership of and transactions in Company stock by executive officers and
directors  of the Company are  required  to be  reported to the  Securities  and
Exchange  Commission pursuant to Section 16(a) of the Securities Exchange Act of
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

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 1996,  the Company used a group of  comparison  companies  (the
"Comparison Group") to determine competitive executive pay levels and practices.
The Comparison Group was composed of 18 leading property/casualty  insurance and
engineering  companies (including five of the six insurance companies in the S&P
500 Property/Casualty  Insurance Index used in the Performance Graphs located on
page 17). Practices  analyzed included pay level and components, stock ownership
levels and short and long-term incentives. 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 1996 to executives as a group,  and for
Mr. Kreh individually, were below the median range of that paid to executives by
the companies in the Comparison  Group according to information  compiled by the
Company's compensation consultant.

   
     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 the Comparison
Group.  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 1996, base salary  adjustments for executives other than
Mr.  Kreh were made for  competitive  reasons  based upon  comparisons  with the
Comparison  Group.  Mr. Kreh  received an 8% base salary  increase  based on the
Committee's  analysis  of  the  comparative  data  for  base  salaries  paid  to
executives with similar responsibilities in the Comparison Group.

     The Company's  Short-Term  Incentive  Plan provides for the annual award of
bonuses to key employees (presently limited to the officer group of the Company,
including  the  executives)  at the  end of the  fiscal  year  provided  certain
performance  measures are  achieved.  Under a schedule  defined by the plan that
establishes  threshold,  target and maximum levels, the Committee  establishes a
pool of  incentive  award  dollars  based on the  actual  percentage  of  Annual
Budgeted  Net  Income  Per Share  (cited in the  Business  Plan of the  Company)
achieved  for the year and the  performance  of the  Company as  compared to the
performance of the insurance  industry and/or other appropriate  industries with
reference to such performance  measures as the Committee deems  appropriate.  In
evaluating Company performance,  the Committee considers such factors as (listed
in order of  importance,  from highest to lowest):  growth in operating  income;
insurance combined ratio;  return on equity;  and engineering  services' margin.
Once the pool is established, individual awards are then determined by the Chief
Executive Officer, based on his evaluation of the participant's contributions to
results  during  the plan  year.  The  awards  may  range  from 0 to 100% of the
participant's  base salary.  The  Committee  determines  the award for the Chief
Executive  Officer and has final  discretionary  authority  over all awards made
under the plan.

     For 1996, the Committee  evaluated  Company results  achieved for 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 1996,
the Actual  Percentage  of Budgeted Net Income Per Share  achieved the threshold
level set under the schedule  defined  under the plan for  establishment  of the
bonus pool. In 1996,  the Committee  determined  that the Company  substantially
outperformed the property/casualty  insurance industry for both return on equity
and insurance  combined ratio (the Company's return on equity for 1996 was 15.6%
and the insurance  combined ratio was 94.7),  and determined  that the Company's
engineering  services'  margin  of 13.2%  was  superior.  Mr.  Kreh was  awarded
$135,000  under  the plan  based on the  Committee's  evaluation  of Mr.  Kreh's
contributions to these results.  Mr. Kreh determined the executives'  awards for
1996,   based  on  his  evaluation  of  these  results,   and  each  executive's
contributions to such results.

     Long-term  incentives are provided to executives  through awards made under
the  Company's   Long-Term   Incentive  Plan.  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 stockholder 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. If the minimum
level of achievement  is not reached for the  Performance  Measures,  the payout
will be zero.
    

        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.  The  maximum  award of
Performance Contingent Units for any participant for a Performance Period cannot
exceed 60% of the participant's  base salary divided by the fair market value of
Company common stock on the first trading day of the Performance Period.  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. For the three-year  Performance Period which runs January 1, 1996 through
December 31, 1998, the  Performance  Measures are net income per share,  expense
ratio and return on equity.

   
        The Committee  determined that payouts to be made under the plan for the
Performance Period ending in 1996 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  Performance  Period  ending  in 1996,  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, 1994. For the 1994 through 1996  Performance  Period,
the net income per share  threshold was not  achieved,  the expense ratio target
was exceeded,  and the return on equity  threshold was exceeded.  Awards made to
executives under the plan for the Performance  Period ending in 1996,  including
Mr. Kreh's award of 2,666 shares of restricted  stock, were calculated under the
award schedule established by the Committee based on these results.
    

        During  1996,  executive  officers  were  eligible  for awards under the
Company's 1995 Stock Option Plan. Plan awards provide  executives with long-term
incentives and reinforce the link between  executives'  long-term  interests and
those of stockholders.  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
at its discretion.  The Company's outside  compensation  consultant reviews each
executive's  award in  comparison  to awards  made to  individuals  employed  by
companies in the Comparison  Group 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 1996, including  competitive  practices at companies in the Comparison Group,
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 1996,  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.
    

        Under Internal Revenue Service rules, 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 stockholders and administered by outside directors.

        Based on the current  provisions of this law, any  compensation  derived
from the exercise of stock options  granted under the 1985 and 1995 Stock Option
Plans or awards made under the Long-Term  Incentive Plan will be exempt from the
limit on the corporate tax deduction.  Any amounts  payable under the Short-Term
Incentive  Plan to the named  executives  would count toward the  limitation  as
would base salary and the value of any vesting  restricted stock under the Stock
Option Plan,  but these  amounts are not expected to reach the $1 million  limit
for any of the  named  executives.  Under  the  current  provisions  of the law,
compensation paid to executives during 1996 was fully deductible and the Company
believes that all compensation paid to executives during 1997 will also be fully
deductible.

(1)  For  1996,   represents  Long-Term  Incentive  Plan  awards  for  1994-1996
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  beginning on page 9.  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.  None of the named  executives held any shares of restricted stock as
of 12/31/96.

(2) The LTIP  payouts  column  shows  cash  payouts  made  under  the  Company's
Long-Term  Incentive  Plan for the  performance  periods  that ended in 1995 and
1994.  Payouts for the performance period that ended in 1996 were made in shares
of restricted stock, as reflected in the Restricted Stock Awards column.

(3)  For  1996,  reflects  Company  contributions  under  the  Company's  Thrift
Incentive Plan.

(4) Compensation for Mr. Basch and Mr. Kerr is reported  beginning in 1995, when
they became executive officers of the Company,  and their 1995 cash compensation
reflects  the fact that they were 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.

(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.

(1) The actual number of performance units awarded at the end of each period, if
any, is not yet determinable because the number of units earned will be based on
Company performance during the Performance Period as described below.


(2) Represents the potential number of Performance  Contingent Units that may be
awarded to participants for the 1996-1998  Performance  Period for the indicated
levels of  performance  under  the  terms of the  Long-Term  Incentive  Plan,  a
detailed  description  of which is  contained in the Human  Resources  Committee
Report on Executive Compensation beginning on page 9.  If the threshold,  target
or maximum  goals are reached,  payouts under the plan will be made in shares of
Company  common  stock  (which  may be  restricted  shares)  at  the  end of the
Performance  Period, or their  corresponding cash value at that time. Awards are
prorated for length of service during the  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, 1996,  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  12/31/96  at age 65 under  the  Company's
qualified  defined benefit  pension plan, as well as  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,  based on  compensation  that is covered  under the plans and years of
service  with  the  Company.   All  of  the  executives  named  in  the  Summary
Compensation  Table  participate in these plans.  (A small portion of Mr. Kreh's
annual retirement  benefit as calculated  pursuant to the table shown below will
be paid from The Boiler Inspection and Insurance Company of Canada's  retirement
plan due to 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 is included in
the year the shares vest due to the expiration of the restricted period of time,
based on the fair  market  value of the shares on the vesting  date.  Restricted
stock awarded  under the  Company's  stock option plans after January 1, 1994 is
not included in the  definition  of earnings  under the plan.  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,  1996 for the  individuals  named in the  Summary  Compensation  Table is as
follows:  Mr. Kreh, 26 years;  Mr. Kelley,  25 years;  Mr. Downs, 24 years;  Mr.
Basch, one year; and Mr. Kerr, one year.

     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 one of the  following two options that has been
selected  by the  executive:  1) an  annual  death  benefit  equal to 50% of the
executive's  base salary for fifteen  years;  or 2) three times the  executive's
base salary at the time of his death.  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 the  retirement  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 stockholders 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 that 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
stockholders  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  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;  (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  amounts  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.

                                   PROPOSAL 2

                  PROPOSAL TO AMEND THE 1995 STOCK OPTION PLAN


     The Board of Directors  believes that the Company's  1995 Stock Option Plan
has been of  substantial  value in  facilitating  the  efforts of the Company to
attract and retain key  employees of  outstanding  ability by providing  them an
opportunity to acquire a proprietary  interest in the Company and giving them an
additional incentive to remain with the Company and to use their best efforts on
its behalf.


   
     The plan  currently  provides  that a maximum of 850,000  shares of Company
common  stock may be issued  pursuant to grants made under the plan and that the
plan will terminate on April 17, 2005. The Board of Directors  believes that the
grants made  pursuant to the plan are an important  component  of the  Company's
overall compensation program and are necessary to attract and retain outstanding
executives and other key employees. On February 1, 1997, 329,650 shares remained
available for future grants to be made pursuant to the plan.  Since the adoption
of the plan in 1995, the Company's  compensation practices have been modified to
make equity  ownership of the Company a larger  component of  compensation,  and
therefore,  the Board of  Directors  believes  the  number  of shares  presently
available  for the grant of awards under the plan will be  insufficient  for the
number of awards to be made by the  Company.  The  Board  therefore  adopted  on
November 3, 1996,  subject to the approval of the stockholders,  an amendment to
the plan which would increase the number of shares subject to issuance under the
plan to 1,850,000.

     The full text of the  proposed  plan  amendment is annexed as Appendix A to
this Prospectus and Proxy Statement.

     The closing price of Company  common stock on March 14, 1997 as reported in
The Wall Street Journal was $46.25.
    


Material Features of the Plan

General

        Executive  and  middle  management  employees  of  the  Company  or  its
subsidiaries  are eligible to participate in the plan. The Board  estimates that
approximately  two hundred  persons  participate in the plan.  Participants  are
recommended by their management.  Under the plan, The Human Resources  Committee
of  the  Board  of  Directors,  as  plan  administrator  (the  "Committee"),  is
authorized to grant incentive and nonstatutory stock options, stock appreciation
rights in tandem  with such  options  and  restricted  stock  awards to eligible
employees.

     As  approved  by  stockholders  at the 1995  Annual  Meeting,  a maximum of
850,000  shares of Company common stock has been reserved for issuance under the
plan.  (If the  proposed  amendment is  approved,  the maximum  number of shares
reserved for issuance will be 1,850,000.) No single  participant  may be granted
awards  pursuant to the plan in excess of 100,000 shares of Company common stock
in any calendar year. The plan permits  adjustments,  in the Board of Directors'
discretion,  in the number of shares of Company  common stock  authorized  to be
issued in the event of stock  splits,  stock  dividends and other changes in the
capitalization  of the Company.  The plan provides that  preferred  stock may be
issued in lieu of common  stock.  The Company has no present  intention to issue
preferred  stock  pursuant to the plan.  Shares of Company  common  stock issued
under  the plan may be newly  issued  or shares  previously  repurchased  by the
Company.

        The Committee is  responsible  for  determining  the type and particular
provisions of awards for eligible  employees and is responsible for interpreting
the plan and for issuing such rules as are necessary for its administration. The
Committee is composed of directors  who are  ineligible  to  participate  in the
plan.

        Under the terms of the plan,  the Board of  Directors  is  permitted  to
amend,  suspend or  discontinue  the plan except that no  amendment  may be made
without  the  approval  of  stockholders  that  increases  the  number of shares
reserved for options and  restricted  stock  awards under the plan,  changes the
class of persons  eligible to  participate,  permits an option  grant at a price
less than fair  market  value or extends the term of the plan or the term during
which an option may be granted or exercised.

Option Grants

        The  plan  provides  that  the  option  price  of  both   incentive  and
nonstatutory  stock option grants will not be less than the fair market value of
Company common stock on the date an option is granted.  The fair market value is
defined as the  average  of the high and low prices per share of Company  common
stock as quoted by the New York Stock Exchange Composite  Transaction  Reporting
System.

     The specific terms of an option grant to a plan  participant are determined
by the  Committee.  However,  in no event may an option be exercised  within one
year of, or beyond ten years from, the date of the grant. In addition, no option
or  associated  stock  appreciation  right may be exercised  more than two years
after termination of the participant's  employment, if such termination occurred
following the death,  disability or retirement of the participant or a change in
control of the Company, as such terms are defined in the plan. If termination of
employment  occurs for any other reason  (other than  termination  for cause) no
option or associated stock  appreciation  right may be exercised more than three
months  following the date of  termination.  However,  if the  participant  dies
within this three-month period, the participant's  beneficiary will be permitted
to exercise the option or stock  appreciation  right within one year of the date
of termination  of employment.  No option may be exercised by a participant or a
beneficiary  beyond the term  specified in the option  grant.  Options and stock
appreciation rights will generally be nontransferable during the lifetime of the
participant,   except  that  the  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.  Payment for the shares as to which an
option is exercised will be made in cash, or if permitted by the  Committee,  in
shares of Company  common  stock that have been held by the  participant  for at
least six months,  or a combination of cash and stock.  The Committee may permit
participants to satisfy,  in whole or in part, 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.

        Under the terms of the plan,  an option grant may, in the  discretion of
the  Committee,  also  include a stock  appreciation  right which will entitle a
participant  to  surrender  the  option,  in whole or in part,  and  receive  in
exchange an amount equal to the excess of the fair market value,  on the date of
surrender,  of the shares  covered by the option  over the option  price of such
shares.  This excess may be paid in shares of Company  common  stock,  cash or a
combination of both, at the discretion of the Committee.

Restricted Stock Awards

         A restricted  stock award is an award of common  shares that may not be
sold, assigned, transferred, or otherwise encumbered, except by will or the laws
of descent  and  distribution,  for a period (the  "restricted  period") of five
years, or such shorter period as the Committee shall determine, from the date on
which the  award is  granted.  The  Committee  may  provide  that the  foregoing
restrictions  shall lapse with respect to specified  percentages  of the awarded
shares on successive  anniversaries  of the date of the award. In addition,  the
Committee  has the  authority  to cancel all or any  portion of any  outstanding
restrictions prior to the expiration of the restricted period.

         During the restricted  period,  the participant is the registered owner
of the shares and is entitled to receive  dividends  with  respect to such stock
and to vote such shares, but participants do not receive stock certificates.  If
during the restricted period the participant's  continuous employment terminates
for any  reason  (other  than by  reason  of death,  disability,  retirement  or
pursuant to a change in control as such terms are defined  under the plan),  any
shares  remaining  subject to restrictions  are forfeited by the participant and
transferred at no cost to the Company,  provided  however,  that as noted above,
the Committee has the  authority to cancel any or all  outstanding  restrictions
prior  to  the  end  of  the  restricted  period,   including   cancellation  of
restrictions in connection with certain types of termination of employment. When
the  restricted  period  ends,  the  restrictions  on  shares  lapse  and  stock
certificates  are  delivered  to  the  participant.  The  Committee  may  permit
participants to satisfy,  in whole or in part, any federal,  state, or local tax
requirements due upon the lapse of such restrictions by delivering already-owned
Company  common stock or by directing the Company to retain Company common stock
otherwise  issuable  to the  participant  upon the  lapse of such  restrictions,
having a fair market value equal to the amount of the tax.

Federal Income Tax Consequences

         A  participant  is not  taxed  upon the grant of a  Nonstatutory  Stock
Option (NSO).  Upon the exercise of an NSO, the participant is taxed at ordinary
income  rates on the  difference  between the fair market value of the shares on
the date of  exercise  and the option  price.  The  Company is entitled to a tax
deduction equal in amount to ordinary income recognized by the participant.  The
participant's basis in the Company common stock acquired upon exercise of an NSO
is equal to the option price plus the amount of ordinary income recognized.

         A  participant  does not  recognize  any income for federal  income tax
purposes upon either the grant or timely  exercise of an Incentive  Stock Option
(ISO).  However,  the spread at exercise will  constitute an item  includible in
alternative  minimum taxable income, and thereby may subject the optionee to the
alternative minimum tax.

         If the participant  holds the shares purchased  through the exercise of
the ISO for two years from the date of the grant of the option and one year from
the exercise date, the participant will be eligible for long-term  capital gains
treatment on the sale of the shares equal to the  difference  between the amount
realized on the sale and the option price.  The Company is not entitled to a tax
deduction in this event.  If the  participant  disposes of the shares within two
years  from the date of the grant or within one year from the  exercise  date (a
"disqualifying disposition"), the participant will be subject to ordinary income
tax treatment on the  difference  between the option price and the lesser of the
fair market  value of the shares on the date of exercise or the amount  realized
on  disposition.  The Company  will be entitled to a tax  deduction  in the same
amount as the ordinary income recognized by the participant.

         The Committee  may, in its  discretion  permit a participant to deliver
previously  acquired shares in payment for the option price of an NSO or ISO. If
the  participant  uses shares of Company common stock to pay the option price of
an NSO,  gain or loss is not  recognized  on the exchange to the extent that the
number of shares  received does not exceed the number turned in as payment.  The
shares  received in the exchange have the same basis and holding  periods as the
shares used for payment.  Any additional shares received upon the exercise of an
NSO have a tax basis  equal to the amount of  ordinary  income  realized  by the
participant and holding period beginning on the date of exercise.

     If the  participant  uses shares of Company  common stock to pay the option
price of an ISO, gain or loss is not generally  recognized on the exchange.  The
equivalent  number of shares  received in exchange for the shares turned in have
the basis and holding  period of the shares  turned in for capital  gain or loss
purposes. Any additional shares received have a zero basis with a holding period
beginning on the exercise date. However, if Company common stock acquired upon a
prior exercise of an ISO is transferred in payment for subsequent exercise of an
ISO or NSO, before the requisite holding periods for the surrendered shares have
been met, the optionee will recognize ordinary income on the gain resulting from
the disposition of such shares. "Gain" for this purpose is defined as the lesser
of i) the  difference  between the fair market value of the stock on the date of
exercise of the first  option and the option price of the first  option,  or ii)
the  difference  between  the  fair  market  value  of the  stock on the date of
exercise of the second option and the option price of the first option.

         Upon the  exercise of a Stock  Appreciation  Right (SAR) a  participant
will be  subject to  ordinary  income  tax  treatment  on the cash plus the fair
market  value of shares of Company  common stock  received.  The Company will be
entitled to a tax deduction in the same amount as the ordinary  income  realized
by the  participant.  A  participant's  basis  in any  stock  acquired  upon the
exercise  of an SAR is  equal  to  the  amount  of  ordinary  income  recognized
excluding any cash received.

     In the case of a restricted  stock award,  a participant  is not taxed upon
the grant of any such  award,  but rather,  the  participant  realizes  ordinary
income in an amount  equal to the fair market  value of Company  common stock at
the time the shares are no longer  subject to a  substantial  risk of forfeiture
(as defined in the Internal Revenue Code [the "Code"]).  The Company is entitled
to a  deduction  at the time and in the  amount  that the  participant  realizes
ordinary income, unless such amount exceeds the limit on compensation payable to
executives pursuant to Section 162(m) of the Code. A participant may elect under
Section  83(b)  of the  Code  (not  later  than 30  days  after  acquiring  such
restricted  shares) to realize ordinary income at the time the restricted shares
are  awarded  in an  amount  equal  to their  fair  market  value at that  time,
notwithstanding  the fact that such  shares are  subject to  restrictions  and a
substantial  risk of  forfeiture.  If such an  election is made,  no  additional
taxable  income  will  be  recognized  by  such  participant  at  the  time  the
restrictions  lapse.  However,  if shares in respect of which such  election was
made are later  forfeited,  no tax deduction is allowable to the participant for
the forfeited shares,  and the Company will be deemed to realize ordinary income
equal to the amount of the  deduction  allowed to the Company at the time of the
election in respect of such forfeited shares.

         It cannot be determined at this time what benefits or amounts,  if any,
will be received  by or  allocated  to any person or group of persons  under the
plan if the  amendment  is adopted or what  benefits or amounts  would have been
received by or  allocated  to any person or group of persons for the last fiscal
year if the amendment had been in effect.

         to motivate such employees to exert their best efforts to contribute to
         the  long-term  growth of the Company by  encouraging  ownership in the
         Company.  The Plan is further  designed to promote a closer identity of
         interest between key employees and the Company's shareholders.

               which is surrendered.

          (b)  "Affiliate"  shall  have the  meaning  set  forth  in Rule  12b-2

               bequest or inheritance or by reason of the death of the Optionee.
               In the case where a  Participant's  right to shares of Restricted

                  options    exercisable   in   cumulative   or   non-cumulative

         (b)      Option Price - The option price per share shall be  determined
                  by the  Committee at the time an option is granted,  and shall
                  not be less than the Fair  Market  Value of one share of Stock
                  on the date the option is granted.

         (c)      Exercise of Option -

                    (1)  Options may be exercised  only by written notice to the
                         Company accompanied by the proper amount of payment for
                         the shares.

                    (2)  The Committee may postpone any exercise of an option or
                         a Stock  Appreciation  Right or the  delivery  of Stock
                         following  the  lapse  of  certain   restrictions  with
                         respect to awards of Restricted  Stock for such time as
                         the Committee in its discretion may deem necessary,  in
                         order to permit the Company with  reasonable  diligence
                         (i) to effect or maintain  registration  of the Plan or
                         the shares  issuable upon the exercise of the option or
                         the Stock  Appreciation  Right or the lapse of  certain
                         restrictions  respecting  awards  of  Restricted  Stock
                         under the  Securities  Act of 1933, as amended,  or the
                         securities laws of any applicable jurisdiction, or (ii)
                         to determine  that such shares and Plan are exempt from
                         such  registration;  the Company shall not be obligated
                         by virtue of any option or any provision of the Plan to
                         recognize  the exercise of an option or the exercise of
                         a Stock  Appreciation  Right or the  lapse  of  certain
                         restrictions  respecting  awards of Restricted Stock to
                         sell or issue shares in violation of said Act or of the
                         law of the government having jurisdiction  thereof. Any
                         such  postponement  shall  not  extend  the  term of an
                         option;  neither  the  Company  nor  its  directors  or
                         officers  shall have any obligation or liability to the
                         Optionee of an option or Stock  Appreciation  Right, or
                         to  the  Optionee's  Beneficiary  with  respect  to any
                         shares  as to which the  option  or Stock  Appreciation
                         Right shall lapse because of such postponement.

                    (3)  To the extent an option is not  exercised for the total
                         number of shares  with  respect to which  such  options
                         become  exercisable,  the number of unexercised  shares
                         shall  accumulate and the option shall be  exercisable,
                         to such extent, at any time thereafter, but in no event
                         later  than ten  years  from the  date the  option  was
                         granted or after the  expiration of such shorter period
                         (if any) which the Committee may have  established with
                         respect to such option  pursuant to  Subsection  (a) of
                         this Section 2.2.

         (d)      Payment of Purchase  Upon Exercise - Payment for the shares as
                  to which an  option is  exercised  shall be made in one of the
                  following ways:

                    (1)  payment in cash of the full option  price of the shares
                         purchased;

                    (2)  if permitted by the Committee, the delivery of Stock of
                         the  Company  held by the  purchaser  for at least  six
                         months   accompanied  by  the   certificates   therefor
                         registered  in the name of such  purchaser and properly
                         endorsed for  transfer,  having a Fair Market Value (as
                         of the  date of  exercise)  equal  to the  full  option
                         price; or

                    (3)  if permitted by the  Committee,  a combination  of cash
                         and Stock (as described in (2) above) such that the sum
                         of the amount of cash and the Fair Market  Value of the
                         Stock (as of the date of exercise) is equal to the full
                         option price.

          (e)  Nontransferability  - No option  granted  under the Plan shall be
               transferable  other  than by will or by the laws of  descent  and
               distribution  subject  to  Section  2.4  hereunder,   unless  the
               Committee  shall permit (on such terms and conditions as it shall
               establish)  such  option  to be  transferred  to a member  of the
               Participant's  immediate  family or to a trust or similar vehicle
               for  the  benefit  of such  immediate  family  members,  or to an
               "alternate   participant"   pursuant  to  a  Qualified   Domestic
               Relations Order as defined in the Code. During the lifetime of an
               Optionee,  an option shall be exercisable  only by such Optionee,
               or if  applicable,  a  transferee.  For  purposes  of Section 2.4
               hereunder,   a  transferred   option  may  be  exercised  by  the
               transferee  to the extent  that the  Participant  would have been
               entitled had the option not been transferred.

          (f)  Laws and  Regulations  - The  Committee  shall  have the right to
               condition  any issuance of shares to any Optionee or  Participant
               hereunder upon such  Optionee's or  Participant's  undertaking in
               writing  to  comply  with  such  restrictions  on the  subsequent
               disposition of such shares as the Committee  shall deem necessary
               or advisable as a result of any applicable law or regulation.  In
               the case of Stock issued or cash paid upon exercise of options or
               associated   Stock   Appreciation   Rights,   or  the   lapse  of
               restrictions  with  respect  to  Restricted  Stock  awarded  to a
               Participant  under the Plan,  the Optionee,  Participant or other
               person  receiving  such Stock or cash shall be required to pay to
               the  Company or a  Subsidiary  the amount of any taxes  which the
               Company or  Subsidiary  is required to withhold  with  respect to
               such Stock or cash. The Company or a Subsidiary  may, in its sole
               discretion,  permit an Optionee or  Participant  or other  person
               receiving  such Stock or cash to satisfy  any  Federal,  state or
               local (if any) tax withholding requirements,  in whole or in part
               by (i)  delivering to the Company or  subsidiary  shares of Stock
               held by such Optionee,  Participant or other person having a Fair
               Market Value equal to the amount of the tax or (ii) directing the
               Company or Subsidiary to retain Stock  otherwise  issuable to the
               Optionee,  Participant  or other  person  under the Plan having a
               Fair  Market  Value  equal to the amount of the tax.  If Stock is
               used to satisfy tax withholding, such Stock shall be valued based
               on the Fair Market Value when the tax  withholding is required to
               be made.

          (g)  Modification  - The Committee  shall have  authority to modify an
               option  without the consent of the  Optionee,  provided that such
               modification  does not affect  the  exercise  price or  otherwise
               materially diminish the value of such option to the Optionee, and
               provided further,  that except in connection with an amendment to
               the Plan,  the  Committee  shall not have  authority  to make any
               modification to any particular  option that materially  increases
               the value of the option to the Optionee.

2.3      Stock Appreciation Rights

          (a)  The  Committee  may,  but shall not be required to, grant a Stock
               Appreciation  Right to the Optionee  either at the time an option
               is granted or by amending  the option at any time during the term
               of such option. A Stock  Appreciation  Right shall be exercisable
               only during the term of the option  with which it is  associated.
               The Stock  Appreciation  Right shall be an  integral  part of the
               option with which it is  associated  and shall have no  existence
               apart  therefrom.  The  conditions  and  limitations of the Stock
               Appreciation Right shall be determined by the Committee and shall
               be set forth in the option or  amendment  thereto.  An  amendment
               granting a Stock  Appreciation  Right shall not be deemed to be a
               grant of a new option for purposes of the Plan.

          (b)  A Stock Appreciation Right may be exercised by:

               (1)  filing with the Secretary of the Company a written election,
                    which  election  shall be delivered by the  Secretary to the
                    Committee specifying:

                    (i)  the option or portion  thereof to be  surrendered;  and
                   (ii)  the  percentage  of the  Appreciation  which  the
                         Optionee desires to receive in cash, if any; and

               (2)  surrendering   such  option  for   cancellation  or  partial
                    cancellation,  as the case may be, provided,  however,  that
                    any election to receive any portion of the  Appreciation  in
                    cash  shall be of no force or  effect  unless  and until the
                    Committee shall have consented to such election.

          (c)  No election to receive  any portion of the  Appreciation  in cash
               shall be filed with the Secretary and no Stock Appreciation Right
               shall be exercised  to receive any cash unless such  election and
               exercise shall occur during the period  (hereinafter  referred to
               as the "Cash Window Period")  beginning on the third business day
               following the date of release for publication by the Company of a
               regular  quarterly or annual  statement of sales and earnings and
               ending on the  twelfth  business  day  following  such date.  The
               Committee  may consent to the election of a holder to receive any
               portion  of the  Appreciation  in cash  at any  time  after  such
               election has been made.  If such  election is  consented  to, the
               Stock  Appreciation  Right shall be deemed to have been exercised
               during the Cash Window Period in which,  or next occurring  after
               which, the Optionee  completed all acts required of such Optionee
               under the preceding paragraphs to exercise the Stock Appreciation
               Right.  Any Stock  Appreciation  Right exercised during said Cash
               Window Period shall be valued and deemed exercised as of the date
               during such Cash  Window  Period when the average of the high and
               low prices for the shares of Stock as reported by the NYSE is the
               highest.

2.4      Exercise of Option or Stock Appreciation Right in the Event of
         Termination of Employment or Death

          (a)  Options and associated Stock Appreciation  Rights shall terminate
               immediately  upon the  termination of the  Optionee's  employment
               with the  Company  or a  Subsidiary  unless  the  written  option
               instrument of such Optionee  provides  otherwise.  The conditions
               established  by the Committee in the  instrument  for  exercising
               options and Stock  Appreciation  Rights following  termination of
               employment are limited by the following restrictions.

               (1)  If  termination  of  employment is by reason of the death of
                    the Optionee, no exercise by the Optionee's  Beneficiary may
                    occur more than two years after the Optionee's death.

               (2)  If  termination of employment is the result of Disability or
                    Retirement,  no exercise by the Optionee or his  Beneficiary
                    may occur more than two years following such  termination of
                    employment.

               (3)  If  termination  of  employment  is for a reason  other than
                    death,  Disability,  Retirement or "involuntary  termination
                    for cause",  no exercise by the Optionee may occur more than
                    three months  following such  termination of employment.  As
                    used herein  "involuntary  termination for cause" shall mean
                    termination  of  employment  by  reason  of  the  Optionee's
                    commission of a felony,  fraud or willful  misconduct  which
                    has resulted,  or is likely to result,  in  substantial  and
                    material damage to the Company or its Subsidiaries.  Whether
                    an involuntary termination is for "cause" will be determined
                    in the sole discretion of the Committee.

          (b)  If the Optionee should die after termination of employment,  such
               termination being for a reason other than Disability,  Retirement
               or  involuntary  termination  for cause,  but while the option is
               still  exercisable,  the option or associated Stock  Appreciation
               Right,  if  any,  may  be  exercised  by the  Beneficiary  of the
               Optionee no later than one year from the date of  termination  of
               employment of the Optionee.

          (c)  Under no circumstances may an option or Stock  Appreciation Right
               be exercised by an Optionee or  Beneficiary  after the expiration
               of the term specified for the option.

2.5      Awarding of Restricted Stock

          (a)  The Committee shall from time to time in its absolute  discretion
               select from among the eligible employees the Participants to whom
               awards of  Restricted  Stock  shall be granted  and the number of
               shares  subject to such awards.  Each award of  Restricted  Stock
               under the Plan shall be evidenced by an  instrument  delivered to
               the  Participant  in such form as the Committee  shall  prescribe
               from time to time in  accordance  with the Plan.  The  Restricted
               Stock  subject to such award shall be  registered  in the name of
               the  Participant  and held in escrow by the Committee  during the
               Restricted Period (as defined herein).

          (b)  Upon the award to a  Participant  of shares of  Restricted  Stock
               pursuant to Section  2.5(a),  the Participant  shall,  subject to
               Subsection  (c) of this  Section  2.5,  possess all  incidents of
               ownership  of  such  shares,   including  the  right  to  receive
               dividends with respect to such shares and to vote such shares.

          (c)  Shares of Restricted  Stock  awarded to a Participant  may not be
               sold, assigned,  transferred,  pledged, hypothecated or otherwise
               disposed  of,   except  by  will  or  the  laws  of  descent  and
               distribution,  for a period of five years, or such shorter period
               as the  Committee  shall  determine,  from the date on which  the
               award is granted (the  "Restricted  Period").  The  Committee may
               also impose such other  restrictions and conditions on the shares
               as it deems  appropriate  and any  attempt to dispose of any such
               shares of Restricted Stock in contravention of such  restrictions
               shall be null and void and without  effect.  In  determining  the
               Restricted Period of an award, the Committee may provide that the
               foregoing  restrictions  shall  lapse with  respect to  specified
               percentages of the awarded shares on successive  anniversaries of
               the date of such award.  In no event shall the Restricted  Period
               end with respect to awarded shares prior to the  satisfaction  by
               the Participant of any liability arising under Section 2.2(f).

          (d)  The restrictions described in Section 2.5(c) shall lapse upon the
               completion  of the  Restricted  Period  with  respect to specific
               shares of Restricted  Stock and the  Participant's  right to such
               shares  shall vest on such date or, if earlier,  on the date that
               the Participant's  employment terminates on account of the death,
               Disability or Retirement  of the  Participant.  The Company shall
               deliver  to  the   Participant,   or  the   Beneficiary  of  such
               Participant, if applicable,  within 30 days of the termination of
               the  Restricted  Period,  the number of shares of Stock that were
               awarded to the  Participant as Restricted  Stock and with respect
               to which the  restrictions  imposed  under  Section  2.5(c)  have
               lapsed,  less any stock  returned  by the  Company to satisfy tax
               withholding pursuant to Section 2.2(f), if applicable.

          (e)  Except  as  provided   in   Sections   2.5(d)  and  (f),  if  the
               Participant's   continuous  employment  with  the  Company  or  a
               Subsidiary shall terminate for any reason prior to the expiration
               of the  Restricted  Period  of an  award,  any  shares  remaining
               subject to  restrictions  shall  thereupon  be  forfeited  by the
               Participant and transferred to, and reacquired by, the Company or
               a Subsidiary at no cost to the Company or Subsidiary.

          (f)  The  Committee  shall  have the  authority  (and  the  instrument
               evidencing an award of Restricted Stock may so provide) to cancel
               all or any portion of any outstanding  restrictions  prior to the
               expiration of the Restricted Period with respect to any or all of
               the shares of Restricted  Stock awarded to an employee  hereunder
               on  such  terms  and   conditions   as  the  Committee  may  deem
               appropriate.

          (g)  In the  event of a Change in  Control,  all  restrictions  on any
               outstanding shares of restricted stock shall lapse as of the date
               of such Change in Control.

         are authorized to execute and deliver written  instruments  evidencing
         awards hereunder,  and amendments thereto, in the name of the Company,
         as directed from time to time by the Committee.

3.2      Adjustments in the Event of Change in Common Stock of the Company

         In the event of any change in the Stock 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 Stock at a price  substantially  below Fair Market
         Value,  or of any similar  change  affecting the Stock,  the number and
         kind of shares which thereafter may be obtained and sold under the Plan
         and the  number and kind of shares  subject  to options in  outstanding
         option  instruments  and the purchase  price per share  thereof and the
         number of shares of Restricted Stock awarded pursuant to Section 2.5(a)
         with  respect  to which  all  restrictions  have not  lapsed,  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 rights  granted to, or available  for,
         Participants  in the Plan.  Any fractional  shares  resulting from such
         adjustments  shall be eliminated.  However,  without the consent of the
         Optionee,  no  adjustment  shall be made in the  terms of an ISO  which
         would  disqualify it from treatment under Section 421(a) of the Code or
         would be considered a  modification,  extension or renewal of an option
         under Section 425(h) of the Code.

3.3      Rights of Employees

         The Plan and any  option  or award  granted  under  the Plan  shall not
         confer  upon any  Optionee  or  Participant  any right with  respect to
         continuance  of employment by the Company or any  Subsidiary  nor shall
         they  interfere in any way with the right of the Company or  Subsidiary
         by which an  Optionee or  Participant  is  employed  to  terminate  his
         employment  at any time.  The Company  shall not be  obligated to issue
         Stock  pursuant to an option or an award of Restricted  Stock for which
         the   restrictions   hereunder  have  lapsed  if  such  issuance  would
         constitute a violation of any  applicable  law. No Optionee  shall have
         any rights as a  shareholder  with  respect  to any  shares  subject to
         option prior to the date of issuance to such  Optionee of a certificate
         or  certificates  for  such  shares.  Except  as  provided  herein,  no
         Participant  shall have any rights as a shareholder with respect to any
         shares of Restricted Stock awarded to such Participant.

3.4      Amendment, Suspension and Discontinuance of the Plan

         The Board may from time to time amend, suspend or discontinue the Plan,
         provided that the Board may not, without shareholder approval, take any
         of the following actions unless such actions fall within the provisions
         of Section 3.2 herein:

          (a)  increase the number of shares  reserved  for options  pursuant to
               Section 1.5;

          (b)  alter in any way the class of persons  eligible to participate in
               the Plan;

          (c)  permit the  granting  of any option at an option  price less than
               that provided under Section 2.2(b) hereof; or

          (d)  extend the term of the Plan or the term  during  which any option
               may be granted or exercised.

         No amendment,  suspension or discontinuance of the Plan shall impair an
         Optionee's  rights  under an option  previously  granted to an Optionee
         without the Optionee's consent.

3.5      Governing Law

         This Plan and all determinations made and actions taken pursuant hereto
         shall be governed by the laws of the State of Connecticut.

3.6      Effective Date of the Plan

         The Plan as amended and restated  shall be effective on April 18, 1995,
         subject to the requisite  approval of shareholders.  No option shall be
         granted  pursuant to this Plan later than April 17,  2005,  but options
         granted before such date may extend beyond it in accordance  with their
         terms and the terms of the Plan.

To:  Employees of The Hartford Steam Boiler Inspection and Insurance Company

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


Date:  March 27, 1997


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, or
the Stock Option and Restricted  Stock Plan), you should receive proxy materials
for this year's  Annual  Meeting to be held on April 24,  1997  through the U.S.
mail shortly.

Annual reports were distributed  under separate cover beginning on March 6, 1997
via bulk mail in order to save on postage  expenses.  HSB has used bulk mail for
several  years for this reason,  and although cost  effective,  it can result in
some delays in delivery.  Proxy materials were  distributed via first class mail
separately beginning on March 26, 1997. You may receive additional copies of the
materials if you hold shares  registered  other than in your name alone. 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 at the
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 under the Stock Option and
      Restricted Stock Plan
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)

If you hold shares jointly with another individual or as custodian for a minor's
account, you will receive a separate card for that account.

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 7, or if you misplace your card,
please contact Jean Cohn, Home Office, Ext. 5724.
