           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)
1.       General

         The interim  consolidated  financial  statements in this report include
         adjustments   based  on  management's  best  estimates  and  judgments,
         including  estimates of future loss  payments,  which are  necessary to
         present  a fair  statement  of the  results  for  the  interim  periods
         reported.  These  adjustments are of a normal,  recurring  nature.  The
         financial  statements  are prepared on the basis of generally  accepted
         accounting  principles  and  should  be read in  conjunction  with  the
         financial  statements  and  related  notes in the 1997  Annual  Report.
         Certain  amounts for 1997 have been  reclassified  to conform  with the
         1998 presentation.

2.       Discontinued Operations

         On January  2, 1998,  the  Company  exercised  its option to put its 40
         percent  share in  Radian  International  LLC  (Radian  LLC) to The Dow
         Chemical  Company,   (Dow)  for  approximately  $129  million,  net  of
         expenses. Radian LLC was formed in January 1996 as a joint venture with
         Dow to  provide  environmental,  engineering,  information  technology,
         remediation and strategic  chemical  management  services to industries
         and governments world-wide. In connection with the formation of the new
         company, the Company contributed substantially all of the assets of its
         wholly-owned subsidiary,  Radian Corporation to Radian LLC. The results
         of Radian LLC were  classified  as  discontinued  operations  following
         ratification  in July 1997 by the Board of  Directors  of  management's
         decision to  exercise  its put.  The  Company's  share of Radian  LLC's
         losses  incurred  subsequent  to such  decision of  approximately  $6.6
         million after-tax was deferred until the closing of the sale on January
         2, 1998. The after-tax gain of $30.3 million  recognized in 1998 is net
         of deferred  losses  noted above.  In 1996 and prior to July 1997,  the
         Company's share of the joint venture's  results were recorded as equity
         in Radian.

3.       Industrial Risk Insurers

         On January 6, 1998, The Hartford Steam Boiler  Inspection and Insurance
         Company  (HSBIIC)  sold  its 23.5  percent  share  in  Industrial  Risk
         Insurers (IRI) to Employers  Reinsurance  Corporation (ERC), one of the
         world's largest reinsurance companies,  in accordance with a previously
         announced   purchase   and  sale   agreement   between  ERC  and  IRI's
         twenty-three  member  insurers.  The gain on the sale of IRI was  $39.0
         million  pre-tax  and  $25.2  million  after-tax.  IRI is a  voluntary,
         unincorporated joint underwriting association,  which provides property
         insurance for the class of business known as "highly  protected  risks"
         (HPR) -- larger  manufacturing,  processing,  and industrial businesses
         which have  invested  in  protection  against  loss  through the use of
         sprinklers and other means. Contemporaneous with the close of the sale,
         IRI was  reconstituted  with ERC (with a 99.5 percent share) and HSBIIC
         (with a .5 percent share) as the sole members.  The new association has
         been renamed HSB Industrial  Risk Insurers.  HSBIIC writes the business
         for HSB  Industrial  Risk  Insurers  using its  insurance  licenses and
         provides certain other management and technical services.  In addition,
         through various reinsurance agreements with ERC and HSB Industrial Risk
         Insurers,  HSBIIC transferred its manufacturing book of business to HSB
         Industrial Risk Insurers and will retain 85% of the equipment breakdown
         insurance and 15% of the property  insurance of the combined  insurance
         portfolio.

4.       Recent Accounting Developments

         In June 1997 the  Financial  Accounting  Standards  Board (FASB) issued
         Statement of Financial  Accounting Standards (SFAS) No. 130 " Reporting
         Comprehensive Income" which requires items that comprise  comprehensive
         income be  reported  in a  financial  statement  display  with the same
         prominence  as  other  financial  statements.  This  presentation  will
         include such items as market value  adjustments of securities,  foreign
         currency  translation,  and certain adjustments made for benefit plans,
         which  are   currently   reported  as  components  of  the  changes  in
         shareholders'  equity.  This  statement is effective  beginning in 1998
         with retroactive restatement of prior periods required.

         Also in June of 1997 the FASB  issued SFAS No. 131  "Disclosures  about
         Segments of an  Enterprise  and  Related  Information".  This  standard
         requires  companies to report  financial  and  descriptive  information
         about   reportable   operating   segments.   It   includes   disclosure
         requirements  relating to products and services,  geographic  areas and
         major  customers.  This statement will be effective  beginning year end
         1998.

5.       Legal Proceedings

         HSBIIC  is  involved  in  two  arbitration  or  litigation  proceedings
         regarding  the extent to which  certain  explosion  events are  insured
         under  boiler and  machinery  policies of HSBIIC or under the  all-risk
         property  insurance  policies  issued  by other  companies.  Management
         believes HSBIIC's policies do not provide coverage for losses resulting
         from the explosion events that are the subject of these proceedings.

         HSBIIC  has  accrued  $6.5  million  with  respect  to these  cases for
         potential LAE, including legal costs to defend HSBIIC's  position.  One
         case is in the  process  of  pre-trial  summary  judgment  motions  and
         appeals;  the other case is involved in both arbitration and litigation
         proceedings.  A trial  date has not been set for  either  case.  In the
         event  that  HSBIIC  is held  liable  for one or both of the  remaining
         claims,  amounts in excess of HSBIIC's net maximum aggregate  retention
         of  $8.5  million  is  recoverable  from   reinsurers.   Claim  amounts
         potentially  recoverable  from  reinsurers  in the event of a  possible
         adverse outcome in these cases could range, in the aggregate,  from $40
         million to $195 million.

         The obligations of HSBIIC's  reinsurers with respect to these cases are
         not  in  dispute.  Therefore,  management  believes  that  any  adverse
         outcomes  in these cases will not,  in the  aggregate,  have a material
         effect on either the results of  operations  or financial  condition of
         the Company.  HSBIIC's  reinsurance  contracts do not require HSBIIC to
         reimburse its  reinsurers  for any losses such  reinsurers  might incur
         should  these  cases not be decided in  HSBIIC's  favor.  Nevertheless,
         reinsurers  often quote rates for future  coverages based upon their or
         other reinsurers' experience on a particular account. Therefore, in the
         event  HSBIIC's   reinsurers  pay  significant  sums  pursuant  to  the
         arbitration or litigation  proceedings  described  above,  it is likely
         HSBIIC's  reinsurance rates would increase in future periods.  However,
         given  the  insured   capacity  that  exists  in  reinsurance   markets
         worldwide,  coupled  with  HSBIIC's  ability to negotiate a redesign or
         restructuring of its reinsurance  program, it does not necessarily mean
         that such an increase would be material.




                                      -8-
<PAGE>



         HSBIIC was involved in a third proceeding  regarding  coverage for loss
         regarding  an explosion  event.  A lower court ruling in that case held
         that an explosion did occur,  and that HSBIIC was not liable for losses
         of the insured resulting from the explosion.  In a further action,  the
         court denied  HSBIIC's  motion for summary  judgment on certain issues,
         thus leaving HSBIIC potentially  liable for certain  unqualified losses
         resulting from events prior to the  explosion.  In the first quarter of
         1997, HSBIIC and the property insurer jointly settled the case with the
         insured. A final allocation of the loss in this case was reached in the
         decision of a mediator  dated  February 2, 1998.  The  decision  had no
         material effect on HSB earnings.

         The Company is also  involved in various  other  legal  proceedings  as
         defendant or co-defendant  that have arisen in the normal course of its
         business.  In the  judgment  of  management,  after  consultation  with
         counsel,  it is improbable  that any  liabilities  which may arise from
         such litigation  will have a material  adverse impact on the results of
         operations or the financial position of the Company.

6.       Earnings per share

         In February 1997, FASB issued SFAS No. 128, "Earnings per Share".  This
         statement  established  standards for computing and presenting earnings
         per share  (EPS).  It replaced the  presentation  of primary EPS with a
         presentation of basic EPS. It also requires dual  presentation of basic
         and   diluted  EPS  on  the  face  of  the  income   statement   and  a
         reconciliation  of the  numerator  and  denominator  of the  basic  EPS
         computation  to  the  numerator  and  denominator  of the  diluted  EPS
         computation.  The  requirements of this statement  became effective for
         year end 1997 financial  statements  with prior  restatement  required.
         Accordingly,  comparative  information  presented  in the  Consolidated
         Statements of Operation have been restated in compliance  with SFAS No.
         128.  Previously,  the company reported EPS of $ 0.78 per share for the
         period ended March 31, 1997.

         On April 21, 1998 the Board of Directors approved a three-for-two stock
         split  for  shares  held of record on May 1,  1998.  Additional  shares
         resulting  from the split will be distributed on or about May 22, 1998.
         In accordance  with SFAS No. 128, all earnings per share  presentations
         have been adjusted to reflect the impact of the stock split,  including
         retroactive restatement of prior periods.

         Earnings per share on a pre-split basis are as follows:

                                                      1998            1997
                                                      ----            ----
            Net income per share-basic               $3.73            $0.78
            Net income per share-assuming dilution   $3.26            $0.78

Net income per common share:

Net income for the first quarter of 1998 included after-tax gains on the sale of
HSB's  interests in Industrial  Risk Insurers (IRI) of $ 25.2 million and Radian
International LLC of $ 30.3 million. The Radian International LLC gain is net of
after-tax  operating  losses of $6.6 million that were deferred in 1997 when the
decision was made to exercise HSB's option to put the Company's  interest to The
Dow Chemical Company.  As a result,  HSB's interest in Radian  International LLC
was classified as a discontinued operation.  Absent these sales, HSB's after-tax
earnings  increased  9.9 percent from the first  quarter of 1997 due to improved
engineering margins and higher realized gains.

Gross earned  premiums  grew 16.7% percent  compared to the prior year.  Much of
this growth is  attributable  to HSB Industrial  Risk Insurers.  Contemporaneous
with the sale of IRI,  the IRI  association  was  reconstituted  with  Employers
Reinsurance Corporation (ERC) (with a 99.5 percent share) and The Hartford Steam
Boiler  Inspection and Insurance  Company  (HSBIIC) (with a .5 percent share) as
sole members. The new association has been renamed HSB Industrial Risk Insurers.
HSBIIC writes the business for HSB Industrial  Risk Insurers using its insurance
licenses and provides  certain other  services.  HSBIIC  transferred  its highly
protected  risk (HPR)  manufacturing  book of  business to HSB  Industrial  Risk
Insurers and through  various  reinsurance  arrangements  with ERC,  HSBIIC will
retain 85  percent of the  equipment  breakdown  business  and 15 percent of the
property business of the combined insurance  portfolio.  This arrangement is the
largest  contributing  factor in the growth of both the gross earned premium and
the ceded  premium.  As a result,  both the Unearned  insurance  premium and the
Reinsurance  assets  reflected  in  the  Consolidated  Statements  of  Financial
Position have increased significantly. The first quarter combined ratio improved
to 89.0  percent in 1998 from 90.0  percent in 1997.  Net  engineering  services
revenue  increased  19.7  percent  for the first  quarter  and  margins  in this
business grew to 8.4 percent from 7.1 percent in the first quarter of 1997.

The  effective  tax rate on  income  from  continuing  operations  for the first
quarter was 32 percent  compared to 26 percent for the comparable  prior period.
Typically tax rate fluctuations  occur as underwriting and engineering  services
results  and  realized  gains  change the mix of pre-tax  income  between  fully
taxable earnings and tax preferred earnings that can be obtained by investing in
certain instruments.  In the first quarter of 1998 the taxes associated with the
sale of IRI contributed to the higher effective tax rate. The Company  continues
to  manage  its  use of tax  advantageous  investments  to  maximize  after  tax
earnings.


Recent Accounting Developments

 In June of 1997 the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information".  This standard requires companies to report
financial and descriptive  information about reportable  operating segments.  It
includes disclosure  requirements relating to products and services,  geographic
areas and major  customers.  This statement will be effective with calendar year
1998,  however  application is not required for interim financial  statements in
the initial  year.  It is possible  that this  standard may redefine our segment
information.  However,  the Company has not yet determined how SFAS No. 131 will
be applied.

Gross  earned  premiums in the first  quarter  increased  16.7  percent from the
comparable  period in 1997. This increase was primarily  attributable to the new
arrangement  with HSB Industrial  Risk Insurers.  Gross earned premiums from IRI
increased $24.6 million in 1998 compared to the comparable period in 1997. Gross
earned premiums  representing  coverage  outside the U.S. for non HSB Industrial
Risk  Insurers  business  increased  5  percent  in the first  quarter  from the
comparable  period in 1997. In certain areas of our direct  domestic and foreign
business,  the market is experiencing price erosion. HSB will not write business
at rates which would lessen our ability to maintain underwriting profit.

                                      -13-

Increases in ceded premium of 140 percent in the current quarter were the result
of both the new HSB Industrial Risk Insurers  arrangement  previously  discussed
and  related  reinsurance  with ERC,  and changes in the  Company's  reinsurance
programs which now utilize more quota share  reinsurance on certain of our books
of  business.  We  anticipate  these  new  reinsurance  contracts  and  the  HSB
Industrial Risk Insurers  arrangement  will continue to result in high growth in
gross earned premium but lower growth in net earned premium.

The loss ratio  increased from 42.1 percent in the first quarter of 1997 to 43.9
percent in the current  quarter.  First  quarter 1998  results were  impacted by
severe  ice  storms  in  Canada.   These  storms  impacted  the  loss  ratio  by
approximately  6 percentage  points.  In the first quarter of 1997 flood related
losses  impacted  the loss  ratio by 1.2  percentage  points.  Gross  claims and
adjustment  expenses for the first  quarter 1998 and 1997 were $89.4 million and
$74.9 million, respectively.

The expense  ratio  improved to 45.1% in the first quarter of 1998 from 47.9% in
the first quarter of 1997.  The new quota share  reinsurance  agreements and the
HSB  Industrial  Risk  Insurers  arrangement  with ERC,  both of which result in
ceding  commissions  to HSBIIC have  positively  impacted  our expense  ratio by
approximately  8  percentage  points.   Ceding  commission  should  continue  to
positively  impact the expense ratio  throughout  1998. A portion of such ceding
commission is intended to reimburse HSB for the additional costs of managing HSB
Industrial Risk Insurers.

Engineering  services  operations  include  the  results  of  HSB's  and  BI&I's
engineering  services,  HSB Reliability  Technologies  (HSBRT) and the Company's
other engineering services subsidiaries.

Net engineering  services  revenues  increased $2.9 million in the first quarter
compared to the same period in 1997. The growth in revenues was primarily due to
increases  generated by HSBRT as their revenues increased 17.7 percent,  as well
as revenues  generated by some recent small  acquisitions which were made in the
latter part of 1997. The improvement in operating gain from the previous periods
reflects efforts to improve staff  utilization and a refocus in certain areas on
pricing  strategies.  We are still incurring costs to develop new products which
have the objective of increasing growth rates.

The Company has been focusing on identifying acquisition candidates in the niche
engineering  management  consulting  service  business,   primarily  in  process
industries, in order to grow the engineering service segment of the business. On
May 1, 1998 HSB and Solomon  Associates,  Inc. (SAI)  announced an agreement for
HSB to acquire SAI.  SAI provides  comparative  performance  benchmarking  to 80
percent of the worldwide  petroleum refining industry and had gross sales of $13
million in 1997.  The company also serves  petro-chemical  and power  generation
customers and conducts performance  improvement  consulting,  business valuation
assessments, performance monitoring and maintenance database services.

Net investment income for the first quarter increased  significantly compared to
the  first  quarter  of 1997 due to the  investment  of  proceeds  from  capital
securities issued during the second half of 1997. In addition, proceeds from the
January  sales  of  HSB's  interests  in  IRI  and  Radian   International   LLC
significantly increased investable funds. Realized investment gains were largely
driven in 1998 by call  premiums on fixed income  investments.  In 1997 realized
gains were reduced by $1.4 million to reflect the estimated  fair value of three
"zero cost" collar contracts  entered into at the end of 1996 which were used to
mitigate the effects of market risk on the U.S.
common stock portfolio.

The Company's  investment  strategy  continues to be to maximize total return on
the investment  portfolio through  investment  income and capital  appreciation.
Investment  strategies  for any given year are  developed  based on many factors
including  operational  results,  tax  implications,   regulatory  requirements,
interest rates, dividends to stockholders and market conditions.  The investment
portfolio  includes a wide variety of high quality  equity  securities  and both
domestic and foreign fixed  maturities.  The Company continues to manage its use
of tax advantageous investments to maximize after tax investment earnings.

Liquidity refers to the Company's  ability to generate  sufficient funds to meet
the cash requirements of its business operations. The Company receives a regular
inflow of cash from maturing  investments and engineering services and insurance
operations.  The mix of the  investment  portfolio  is  managed  to  respond  to
expected claim pay-out  patterns and other cash  requirements.  The Company also
maintains a highly liquid  short-term  portfolio to provide for  immediate  cash
needs and to offset a portion of interest rate risk relating to certain  capital
securities.

Cash  provided from  operations  was $ 15.4 million in the first three months of
1998  compared to $29.4  million for the same period in 1997.  The  reduction is
primarily the result of the timing of settlement of portfolio  transfers related
to IRI in the first  quarter of 1998 as compared  to the first  quarter of 1997.
Aside from IRI activity,  premiums  collected were  essentially flat compared to
the first quarter of 1997 while claims paid declined  approximately  36 percent.
Net settlements with reinsurers declined 41 percent in the same time period.

Capital resources consist of shareholders'  equity,  capital securities and debt
outstanding  and represent  those funds  deployed or available to be deployed to
support  business  operations and investment  activities.  Common  shareholders'
equity of $411.3  million at March 31, 1998  increased  by $66.0  million  since
December 31, 1997. The increase  primarily  reflects net income of $72.9 million
for the  quarter  and an  increase  in  unrealized  gains,  net of tax, of $17.7
million,   offset  by  common  dividends  of  $11.7  million  and  common  stock
repurchases of $19.7 million.

At March  31,  1998,  the  Company  had  significant  short-term  and  long-term
borrowing  capacity.  The  Company is  currently  authorized  to issue up to $75
million of commercial paper.  Commercial paper outstanding at March 31, 1998 was
$.9 million

The Company is involved in two arbitration or litigation  proceedings  regarding
the extent to which  certain  explosion  events  are  insured  under  boiler and
machinery  policies  of the  Company or under the  all-risk  property  insurance
policies issued by other companies.  Management  believes the Company's policies
do not provide  coverage for losses resulting from the explosion events that are
the  subject of these  proceedings.  In the  opinion of  management  any adverse
outcomes in these cases will not, in the  aggregate,  have a material  effect on
either the results of  operations  or financial  condition of the Company.  More
information  pertaining to these legal  proceedings may be found under note 5 of
the Notes to Consolidated Financial Statements herein.

The Company continues to evaluate the potential  coverage  exposures arising out
of the  year  2000  and its  impact  on  insured  equipment.  As has  been  well
publicized,  many computer  systems and date  controlled  equipment may cease to
function  or may  function  in a  different  manner  when the year 2000  arrives
because they are  programmed to recognize  only the last two digits of the year.
During the first  quarter the Company  filed with the various  jurisdictions  an
endorsement to its equipment  breakdown forms which  reiterates that coverage is
not provided for the inherent inability of computers and computerized  equipment
to  properly  recognize  a  particular  date or  time,  such as the  year  2000.
Quantification of the Company's  exposure to year 2000 losses is not possible at
this time as  applicable  policy  wordings  have not been legally  tested in the
context of such losses.  See discussion on other year 2000  uncertainties in the
Management's  Discussion and Analysis of  Consolidated  Financial  Condition and
Results of Operations in the Company's 1997 Report on Form 10-K.

Forward-Looking Statements

Certain statements contained in this report are forward-looking and are based on
management's  current  expectations.  Actual results may differ  materially from
such  expectations  depending on the outcome of certain  factors  described with
such forward-looking statements and other factors including: significant natural
disasters  and severe  weather  conditions;  changes in  interest  rates and the
performance  of the financial  markets;  changes in the  availability,  cost and
collectibility of reinsurance; changes in domestic and foreign laws, regulations
and taxes; the entry of new or stronger  competitors and the  intensification of
pricing  competition;  the loss of current  customers or the inability to obtain
new customers;  changes in the coverage  terms selected by insurance  customers,
including higher deductibles and lower limits; adverse development on losses and
loss  adjustment  expenses  related  to claims  arising  in prior  periods;  new
insurance and reinsurance  contract  interpretations,  including coverage issues
related to Year 2000  events;  changes in asset  valuations;  consolidation  and
restructuring  in the  financial  services  industry;  changes in the  Company's
participation in joint underwriting associations, and in particular IRI; changes
in the demand and customer base for engineering and inspection  services offered
by the Company,  whether  resulting  from changes in the law or  otherwise,  and
other general market conditions.


                          PART II - OTHER INFORMATION

Item 1.  Legal Proceedings
- --------------------------

          HSBIIC  is  involved  in two  arbitration  or  litigation  proceedings
          regarding  the extent to which  certain  explosion  events are insured
          under  boiler and  machinery  policies of HSBIIC or under the all-risk
          property  insurance  policies  issued by other  companies.  Management
          believes   HSBIIC's  policies  do  not  provide  coverage  for  losses
          resulting  from the  explosion  events  that are the  subject of these
          proceedings.

          HSBIIC has  accrued  $6.5  million  with  respect  to these  cases for
          potential LAE, including legal costs to defend HSBIIC's position.  One
          case is in the  process of  pre-trial  summary  judgment  motions  and
          appeals; the other case is involved in both arbitration and litigation
          proceedings.  A trial  date has not been set for either  case.  In the
          event  that  HSBIIC is held  liable  for one or both of the  remaining
          claims,  amounts in excess of HSBIIC's net maximum aggregate retention
          of  $8.5  million  is  recoverable  from  reinsurers.   Claim  amounts
          potentially  recoverable  from  reinsurers  in the event of a possible
          adverse outcome in these cases could range, in the aggregate, from $40
          million to $195 million.

                                      -18-
<PAGE>

          The obligations of HSBIIC's reinsurers with respect to these cases are
          not in  dispute.  Therefore,  management  believes  that  any  adverse
          outcomes in these cases will not,  in the  aggregate,  have a material
          effect on either the results of operations  or financial  condition of
          the Company.  HSBIIC's reinsurance  contracts do not require HSBIIC to
          reimburse its  reinsurers for any losses such  reinsurers  might incur
          should  these  cases not be decided in HSBIIC's  favor.  Nevertheless,
          reinsurers  often quote rates for future coverages based upon their or
          other reinsurers'  experience on a particular account.  Therefore,  in
          the event  HSBIIC's  reinsurers pay  significant  sums pursuant to the
          arbitration or litigation  proceedings  described  above, it is likely
          HSBIIC's reinsurance rates would increase in future periods.  However,
          given  the  insured  capacity  that  exists  in  reinsurance   markets
          worldwide,  coupled with  HSBIIC's  ability to negotiate a redesign or
          restructuring of its reinsurance program, it does not necessarily mean
          that such an increase would be material.

          HSBIIC was involved in a third proceeding  regarding coverage for loss
          regarding an explosion  event.  A lower court ruling in that case held
          that an explosion did occur, and that HSBIIC was not liable for losses
          of the insured resulting from the explosion.  In a further action, the
          court denied HSBIIC's  motion for summary  judgment on certain issues,
          thus leaving HSBIIC potentially liable for certain  unqualified losses
          resulting from events prior to the explosion.  In the first quarter of
          1997,  HSBIIC and the property  insurer  jointly settled the case with
          the insured.  A final  allocation of the loss in this case was reached
          in the decision of a mediator dated February 2, 1998. The decision had
          no material effect on HSB earnings.

          The Company is also  involved in various  other legal  proceedings  as
          defendant or co-defendant that have arisen in the normal course of its
          business.  In the  judgment of  management,  after  consultation  with
          counsel,  it is improbable that any  liabilities  which may arise from
          such litigation will have a material  adverse impact on the results of
          operations or the financial position of the Company.

                               OPERATING AGREEMENT
                                       for
                       HSB-IRI PROPERTY INSURANCE BUSINESS

         This  Operating  Agreement is entered  into  effective as of January 1,
1998,  by  and  among  Employers  Reinsurance   Corporation  (ERC),  a  Missouri
corporation having a principal place of business at 5200 Metcalf, Overland Park,
Kansas;  HSB  Industrial  Risk Insurers  L.L.C.  (LLC),  a  Connecticut  limited
liability  corporation  having a  principal  place of  business  at 85  Woodland
Street, Hartford, Connecticut; Industrial Risk Insurers (IRI), an unincorporated
joint  underwriting  association  having a  principal  place of  business  at 85
Woodland Street, Hartford, Connecticut; and The Hartford Steam Boiler Inspection
and Insurance Company (HSB), a Connecticut  corporation having a principal place
of business at One State Street, Hartford, Connecticut.

WHEREAS,  ERC, pursuant to the Asset and Capacity Sale Agreement and through its
subsidiary  organization,  IRI Management  Services L.L.C.  (IMS), has acquired,
effective as of January 1, 1998,  certain of the tangible and intangible  assets
of IRI  and  its  affiliated  Canadian  association,  Canadian  Industrial  Risk
Insurers  (CIRI),  both of which are joint  underwriting  associations  offering
first  party  property  insurance  to highly  protected  risk (HPR)  accounts in
industrial/manufacturing occupancies; and

WHEREAS,  pursuant to the Asset and Capacity Sale Agreement,  efffective January
1, 1998 IRI has been  reconstituted with ERC having a 99.5% share and HSB having
a .5% share and ERC and HSB have  agreed to reinsure  the former  members of IRI

                  deducted from the Ceding Commissions to be paid to HSB.

                  2.1.3.2  In  operation  of  the  HSB-IRI  BUSINESS,  it is the
                  general intent of the parties to perform, or to have performed
                  a)  customer   relationships,   marketing,   and  underwriting

         2.1.4 Insurance  Policies Issued by HSB.  Insurance  policies issued in

         or IRI as determined by the Members of the LLC. Any policies  reinsured
         by CIRI will be reinsured 100% by IRI.  Reinsurance by IRI of HSB, BI&I
         or CIRI  will be in  accordance  with  the  IRI  Reinsurance  Agreement
         attached  hereto as Exhibit B, and therefore,  ERC and HSB, as the sole
         members of IRI,  will be liable for  losses  under IRI policy  forms in
         accordance  with  the  Constitution  of  IRI  in  proportion  to  their
         respective  membership  shares in the IRI. It is contemplated  however,
         that such risk will be  reapportioned  between ERC and HSB  pursuant to
         reinsurance   agreements   executed   between   each  of  ERC  and  HSB
         substantially  in the form attached hereto as Exhibit C and D such that
         HSB will be liable for 85% of the boiler and  machinery  losses and 15%
         of all other  property  insurance  losses  associated  with the HSB-IRI
         BUSINESS,  and  ERC  will be  responsible  for  15% of the  boiler  and
         machinery  losses  and  85%  of all  other  property  insurance  losses
         associated with the HSB-IRI  BUSINESS.  Notwithstanding  the foregoing,
         ERC and HSB at some future date may agree to apportion HSB-IRI BUSINESS
         written  by  HSB  pursuant  to  this  Agreement  in  accordance  with a
         Reinsurance  Agreement  to be  executed  between  ERC and HSB  directly
         without ceding 100% of such business to/or through IRI. Upon request of
         any Intermediary,  ERC agrees to furnish a Guarantee,  substantially in
         accordance  with the form  attached  hereto as  Exhibit  E,  which will
         guarantee the direct payment to the insured of its IRI membership share
         of liability for losses,  net of any reinsurance  recoverable from HSB,
         pursuant to the HSB Reinsurance Agreement,  unless ERC has a reasonable
         basis for refusing to issue such a guarantee.

         2.1.7 Loss Adjustment Expenses.  Loss Adjustment Expenses shall be paid
         by ERC and/or HSB in connection  with,  and in proportion  to, any loss
         paid  in  accordance   with  Paragraph   2.1.6,  as  adjusted  for  any
         retrocession  made to HSB and ERC or any direct  reinsurance  of HSB by
         ERC as contemplated by Paragraph 2.1.6.

                        AND EXPENSE REIMBURSEMENT TO IRI



6.1 IRI Working  Capital Fund. ERC and HSB will establish an IRI Working Capital
Fund to be used to fund the day-to-day  operations of IRI in performing services
delegated to it by HSB in accordance  with this  Agreement.  The Working Capital
Fund  will  be  funded  by HSB  and  ERC in  accordance  with  their  respective

will be in the amount of $25 Million., of which ERC will contribute  $24,875,000
and HSB will contribute $125,000.

6.2 Funding Level.  The IRI Working  Capital Fund shall be funded on an on-going
basis  at a level  reasonably  estimated  by IRI on the  basis  of its  previous
experience to cover not more than two months' operating expenses for the HSB-IRI
BUSINESS. Reimbursements made by HSB pursuant to Paragraph 6.5 shall be credited
to such fund when  received.  Any cash on hand will be  invested  in  short-term
instruments  as  directed by HSB and the  investment  earnings  thereon  will be
credited to the Fund.

6.3 Funding of IRI Working Capital Fund Shortfall.  Within 15 days following the
end of each  month IRI shall  prepare  and  submit to HSB a  detailed  statement
supporting  its claim  for  reimbursement  of  expenses  paid by it  during  the
previous month in performing services in accordance with this Agreement.  At the
same time IRI shall  determine  the  amount of funds,  if any,  it  requires  to
maintain the funding level  specified  under  Paragraph 6.2, taking into account
the reimbursement claim for such month that IRI anticipates submitting to HSB in
accordance  with Paragraph 6.7 and any other  receivables.  Any shortfall in the
funding level shall be paid by HSB and ERC in accordance  with their  membership
shares within 15 days after receiving the statement reporting such shortfall.

accordance  with the provisions  contained in Section 5.3 of the ERC Reinsurance
Agreement  and Section  5.3 of the HSB  Reinsurance  Agreement.  The Claims Fund
shall initially be funded .5% by HSB and 99.5% by ERC in an aggregate  amount of
$1,000,000.  Thereafter,  any shortfall in the Fund will be funded in accordance
with each party's proportionate share of the losses giving rise to the shortfall
after taking into account the ERC and HSB Reinsurance Agreements. Such shortfall
will be determined within 15 days after the end of each month and will be funded
by the parties in accordance  with the preceding  sentence  within 15 days after
receiving  the  statement  reporting  such  shortfall.  The Claims  Fund will be
invested  in  short-term  instruments  as  directed  by HSB and  the  investment
earnings thereon will be credited thereto prior to determining any shortfall.

6.5 Offsets from Reimbursement Obligation. The following amounts shall be offset
against the reimbursement IRI is entitled to under this Article VI:

         (i) any revenues for engineering,  technical services,  underwriting or
         other  similar  administrative  services  performed  by  IRI  or HSB in

         and  (ii)   amounts   receivable   by  IRI  and  ERC  pursuant  to  the

         hereunder.

Other "fee for  service"  revenues  collected  by IRI and not  includable  under
subparagraph  (i)  above  will  not  be  treated  as  an  offset  against  HSB's
reimbursement  obligation.  Such  revenues  and  any  related  expenses  will be
accounted  for in the  manner  determined  by HSB  and ERC  pursuant  to the LLC
Agreement.

6.6  Restructuring and Transitional  Expenses.  HSB shall not be responsible for

                  jurisdictional    authorities   in   connection    with   such
                  inspections) and overdue engineering service commitments under
                  IRI  service  plans in effect  on the date of this  Agreement.

                  to be developed  and agreed upon by HSB and ERC within  thirty

         6.7.1 Requests for reimbursement of expenses of IRI,  supported by such
         documentation and detail as HSB may reasonably  request,  shall be paid
         by HSB within 30 days  following  receipt of such  request,  except for
         such  specific  expense  items which HSB is disputing  pursuant to this
         Paragraph 6.7.

         6.7.2  Any  allocated  costs  for  the  use  of  the  assets  of IMS in
         connection with the HSB-IRI  BUSINESS shall be calculated  using proper
         cost  accounting  methods  and  principles.   Any  rental  payments  in

                                   ARTICLE VII

                               COMPENSATION TO HSB

7.1 Ceding  Commission for  Reinsurance  Ceded to IRI.  Subject to any agreement
between ERC and HSB under which ERC agrees to directly reinsure HSB with respect
to the HSB-IRI BUSINESS, HSB agrees to cede and IRI agrees to accept 100% of the
liability,  including  loss  adjustment  expenses,  under  policies  written  in
connection with the HSB-IRI BUSINESS in accordance with the terms and conditions
of the IRI  Reinsurance  Agreement  attached hereto as Exhibit B. As premium for
the  reinsurance,  HSB shall pay to IRI 100% of the gross  premiums  written  in
connection with such business,  less a ceding commission of 33% which,  together
with the Ceding  Commissions  provided under Paragraph 7.2, shall compensate HSB
for the services it performs in connection with this Agreement.

7.2 Ceding Commission on Other Business.  With respect to reinsurance  contracts
entered into in connection with the HSB-IRI BUSINESS under which IRI acts as the
assuming  reinsurer,  HSB shall be paid a Ceding  Commission of 33% of the gross
written premium ceded to IRI pursuant to such reinsurance contracts.

7.3      Quarterly Sharing in Savings/Expenses.

         7.3.1 In the  event  that the  annual  Expense  Ratio  for the  HSB-IRI
         BUSINESS  is in excess of 30%,  HSB and ERC will  share  equally in the
         amount of Operating Costs comprising such excess. In the event that the
         annual  Expense  Ratio is below 30%, HSB and ERC will share  equally in
         any savings in Operating Costs with respect to Expense Ratios below 30%
         and at or above 26%, and will share in any savings in  Operating  Costs
         below an Expense Ratio of 26% on the basis of ERC receiving a 75% share
         and HSB receiving a 25% share.

         7.3.2 Within 30 days  following  the end of each  calendar  quarter HSB
         will  calculate and notify ERC of the actual year-to date Expense Ratio
         for operating the HSB-IRI BUSINESS.  The Expense Ratio will be computed
         as follows:

         X / Y

         where:
         X= Operating Costs on a year-to-date basis Y= Gross Written Premiums on
         a year-to date basis

         7.3.3 On the basis of the notice  prepared by HSB pursuant to Paragraph
         7.3.2,  ERC or HSB shall  remit to the  other,  as the case may be, any
         amounts owed to the other after giving effect to the  allocation of any
         expenses/costs  savings set forth in Paragraph 7.3.1 above, taking into
         account  any  amounts  which have been  remitted  to each other for any
         prior quarters within such calendar year.

         7.3.4 Attached as Exhibit F is a pro forma business plan for 1997 and a
         projected business plan for 1998 assuming the HSB-IRI BUSINESS had been
         operated under this Agreement  commencing on January 1, 1997. Exhibit F
         illustrates  the  application  of the  calculation  set  forth  in this
         Paragraph 7.3.

7.4 Adjustment to Ceding Commission.  It is the intent of the parties to operate
the  HSB-IRI  BUSINESS  at an  expense  ratio  of 33% or less of  Gross  Written
Premiums,  inclusive of HSB's policy issuing and service costs  calculated at 3%
of Gross Written  Premiums,  and to share  equally,  as illustrated in Paragraph
7.3,  Operating Costs in excess of 30% and savings in Operating Costs below 30%.
However, in the event that the initial expense structure exceeds such 30%, or in
the event that any external factor, including but not limited to a change in the
commission structure paid brokers or agents (including  incentive  commissions),
causes the expense ratio to exceed the  indicated  30% on a constant  basis then
the  parties  agree to  reexamine  the  level of  commissions  set forth in this
Article VII (and in the IRI,  ERC and HSB  Reinsurance  Agreements)  in a manner
that  provides HSB with  reimbursement  of the policy  issuing and service costs
calculated at 3% of Gross Written Premium as set forth above.

               of Performance Contingent Units shall be established for minimum,
               target  and  maximum   attainment   of  such  goal.   The  actual
               Performance  Contingent  Award to be paid to a Participant at the
               conclusion of the Performance  Period shall be based on the level
               of  attainment  of the  Performance  Goals  established  for such
               period.  The Committee may designate that Performance  Contingent
               Awards shall be credited  with  Dividend  Equivalents  during the
               Performance  Period  which  shall be paid when and if such awards
               are paid.

          (b)  After Performance Goals have been established,  they shall not be
               modified  in  respect  to the  Performance  Period to which  they

          (a)  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.  A
               Participant shall be entitled to receive payment of an amount not
               exceeding   the  Fair  Market  Value  of  the  maximum  award  of
               Performance   Contingent  Units   established  by  the  Committee
               pursuant to Section 6 hereof  based upon the level of  attainment
               of  the  Performance  Goals  determined  by  the  Committee.  The
               Committee  shall  have the  authority  to reduce the award of any
               Participant  even if the Performance  Goals  attributable to such
               award  have been  met.  The  Committee  shall  have no  authority
               hereunder  to  increase  any award  calculated  under  this Plan,
               except in accordance with Section 16.

          (b)  As soon as practicable  following  certification by the Committee
               pursuant to Section 7(a), payment of awards to Participants shall
               be  made.  Payments  shall be made in  cash,  a Stock  Grant or a
               combination  of the  foregoing as prescribed by the Committee and
               shall be subject to such other conditions and restrictions as the
               Committee shall establish.
         
          (c)  Payment of any award of Dividend Equivalents shall be made at the
               same time as payment of the Performance Contingent Award to which
               it  relates  and  shall  be made in  cash  or a  Stock  Grant  as
               prescribed by the Committee.

               Units  (determined as of the first trading day of the Performance
               Period)  and  Dividend  Equivalents  which may be  awarded to any
               Participant  for any  Performance  Period  shall  not  exceed  $2
               million.

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  Performance
               Contingent  Award  and  related  Dividend  Equivalents.  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 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.

          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

               otherwise  than  pursuant to Section 12.  There is no  obligation
               imposed  on  the  Committee   for   uniformity  of  treatment  of

               in the employ of the Company.

11.       Rights on Termination of Employment

          (a)  If a Participant in this Plan shall terminate employment with the

               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.

     member of the  Committee  shall be a  "disinterested  director"  within the
     meaning  of Rule 16b-3 of the  General  Rules and  Regulations  promulgated

     appropriate.  Such  guidelines  shall be  consistent  with the Plan and may
     include,  but need not be  limited  to,  the size and terms of awards to be

     Committee  shall  be  final,   conclusive  and  binding  upon  all  parties
     concerned,  unless  otherwise  determined  by a vote of a  majority  of the
     disinterested members of the Board of Directors.


4.   Eligibility for Awards

     Any employee  who is an Officer of the Company  (other than any Officer who
     is the chief  executive  officer of any  Affiliate  of the Company and is a
     participant in the annual bonus plan of such subsidiary,  or any individual
     expressly  excluded  by the  Committee)  on or prior to December 31 of each
     Plan Year is  eligible  to  participate  in the Plan and  receive  an Award
     pursuant to Section 5 except as 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
          written consent of the Committee.

     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.  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.

shares lapse as described herein.

(c)  Restricted  Stock  awarded  to  a  Director  may  not  be  sold,  assigned,

consent of a majority of the Board of Directors.

(d) If a Director's service on the Board terminates for reasons other than those
provided in Section 7(c), any shares  remaining  subject to  restrictions  shall
thereupon be forfeited by the Director and  transferred to and reacquired by the
Company  at no cost to the  Company,  and any  Restricted  Stock  credited  to a
Director but not yet awarded pursuant to Section 7(a) shall not be awarded.

(e) After the shares of Restricted Stock are actually awarded,  Directors shall,
subject to Section  7(c),  possess all  incidents  of ownership of the shares of
Restricted  Stock including the right to receive  dividends with respect to such
shares and to vote such shares. Dividends will be paid to Directors in cash.

8. Election to Defer Receipt of Cash Compensation.

(a) A Director  shall have the right to make on an annual  basis an  election to
defer  payment of all, or a  percentage  of, the total Cash  Compensation  to be
earned during the ensuing Plan Year (a "Deferral Election").  In order to make a
Deferral  Election  pursuant to this Section 8, a Director  shall deliver to the
Corporate  Secretary of the Company no later than the last business day prior to
the commencement of the first Plan Year to which such election relates a written
notice  setting  forth the  percentage of Cash  Compensation  to be deferred and
whether  such cash  should  be (i)  converted  into  Stock  Equivalent  Units in
accordance with  subsection (b) below;  (ii) converted into shares of Restricted
Stock in accordance  with  subsection (c) below;  or (iii) credited as cash to a
Deferred  Account  maintained  for such  Director on the date such  compensation
would  otherwise be paid.  Individuals who become  Directors  during a Plan Year
shall have  thirty  days  following  their  election  or  appointment  to make a
Deferral Election for the remainder of the Plan Year. Any Deferral Election made
pursuant  to this  Section 8 shall  remain in effect for  subsequent  Plan Years
until a new election form is delivered to the Corporate  Secretary in accordance
with this section.

(b) As soon as practicable  following the end of a Plan Year,  each Director who
made a Deferral  Election in the form of Stock Equivalent Units will be credited
as of the  last  day of the  Plan  Year  with the  number  of  units,  including
fractional units, equal to the amount of the Cash  Compensation,  the payment of
which has been deferred,  divided by the Fair Market Value of shares of Stock on
the date such  compensation  would otherwise have been paid. In the event that a
Director's  service on the Board terminates for any reason prior to the end of a
Plan Year, the calculation  referred to in the preceding  sentence shall be made
as soon as practicable following such Director's date of termination.

(c) As soon as practicable  following the end of a Plan Year,  each Director who
made a Deferral  Election in the form of Restricted  Stock will be awarded as of
the last day of the Plan Year the  number of whole  shares of  Restricted  Stock
approximately equal to the amount of the Cash Compensation, the payment of which
has been  deferred,  divided by the Fair Market  Value of shares of Stock on the
date such  compensation  would  otherwise have been paid. Any fractional  number
obtained by dividing  the amount of Cash  Compensation  by the Fair Market Value
will be rounded up or down to the nearest  whole number of shares.  In the event
that a Director's  service on the Board  terminates as a result of circumstances
described  in  Section  7(c) prior to the end of a Plan  Year,  the  calculation
referred  to in the  preceding  sentence  shall  be made as soon as  practicable
following  such  Director's  date of  termination  and payment  shall be made in
shares of Stock.

9. Dividend  Equivalents  Payable on Stock Equivalent Units and Restricted Stock
and Interest Paid on Deferred Cash Accounts.

(a) Dividend  Equivalents  shall be credited on Stock  Equivalent  Units held by
Directors  based upon  dividends  paid on shares of Stock  between the date such
Stock  Equivalent  Units  are  credited  to  Directors  and the  date  they  are
ultimately paid out in accordance with the Plan.

(b) Dividend  Equivalents shall, at the election of the Director,  be either (i)
paid in the  form of cash  as soon as  practicable  following  the end of a Plan
Year; or (ii) converted into Stock  Equivalent Units following the end of a Plan
Year based on the number of Stock  Equivalent  Units  credited  to a  Director's
account,  plus, if  applicable,  the number of shares of Restricted  Stock to be
awarded  pursuant to Section 7 for a Plan Year, as of the dividend  record dates
falling  within such Plan Year  multiplied  by the cash  dividends  (or the fair
market  value of any property  other than cash paid as a dividend)  per share of
Stock payable during such Plan Year divided by the Fair Market Value of Stock on
the last day of the Plan Year.

(c) Dividend  Equivalents  will be payable on Stock  Equivalents  Units  granted
under Section 6 for the Plan Year for which a grant is made in  accordance  with
subsections  (a) and (b) above as though  such Stock  Equivalent  Units had been
granted as of the first day of such Plan Year,  provided however,  such Dividend
Equivalents shall not be credited to a Director until the Stock Equivalent Units
to which they relate are credited to the Director in accordance with Section 6.

(d) Dividend Equivalents will be payable on Restricted Stock to be granted under
Section 7 for the Plan Year for which an Annual  Grant is to be made  based upon
dividends  paid on shares of Stock for such Plan Year as though such  Restricted
Stock had been granted as of the first day of such Plan Year,  provided however,
such Dividend  Equivalents  shall not be credited to a Director until the shares
of Restricted Stock to which they relate are actually awarded to the Director in
accordance with Section 7. Dividend Equivalents credited under this Section 9(d)
shall be payable in accordance with Section 9(b).

(e) Dividend  Equivalents  will be payable on Stock  Equivalent  Units  credited
pursuant  to a  Deferral  Election  pursuant  to  Section 8 in  accordance  with
subsections  (a) and (b) above as though  such Stock  Equivalent  Units had been
credited to a Director on the date the Cash  Compensation  to which the Deferral
Election relates would otherwise have been paid, provided however, such Dividend
Equivalents  shall  not be  credited  to a  Director's  account  until the Stock
Equivalent Units to which they relate are credited to the Director in accordance
with Section 8.

(f) Dividend  Equivalents will be payable on shares of Restricted Stock credited
but not yet actually awarded pursuant to a Deferral Election pursuant to Section
8,  based  upon  dividends  paid on shares of Stock  between  the date such Cash
Compensation  to which the Deferral  Election  relates would otherwise have been
paid and the date the shares of Restricted Stock are actually awarded,  provided
however, such Dividend Equivalents shall not be credited to a Director's account
until the shares of Restricted  Stock to which they relate are actually  awarded
to the Director in  accordance  with Section 8.  Dividend  Equivalents  credited
under this Section 9(f) shall be payable in accordance with Section 9(b).

(g) At the end of each Plan Year, and at the time of payment of any amounts held
in a  Deferred  Account,  interest  at the rate of the  average of the yields at
issuance of five-year Treasury Notes issued during the prior twelve-month period
plus 1% shall be credited to each Deferred  Account on the average daily balance
held in such accounts for the preceding Plan Year or portion thereof.

10. Time and Form of Payment.

(a) Payment in  settlement of Stock  Equivalent  Units and any amounts held in a
Deferred  Account  will  commence  as soon as  practicable  after  the  date the
Director  ceases to be a member of the Board,  unless,  with  respect to amounts
held in a Deferred Account, a Director has specified an alternate date in his or
her Deferral Election.

(b) Payment in  settlement of Stock  Equivalent  Units and any amounts held in a
Deferred  Account  will be made in a lump sum or, if elected  by a  Director  at
least  one year  prior to the date  such  Director  ceases to be a member of the
Board, in a specified  number (not to exceed ten) of annual  installments.  Such
election  may be  modified  or revoked by the  Director,  provided  that no such
modification  or revocation  will be given effect unless it is made prior to the
date specified in the preceding sentence.

(c)  Amounts  held in a  Deferred  Account  shall  be paid  in  cash  and  Stock
Equivalent  Units held by a Director  shall be paid in an  equivalent  number of
shares of Stock unless prior to the  commencement of payment,  a Director elects
to receive a cash payment in lieu of shares of Stock. Such cash payment shall be
equal to the Fair Market Value of the shares on the date such Director ceases to
be a  member  of the  Board,  or in the  case of an  installment  election  made
pursuant to  subsection  (b) above,  on the  anniversary  date of such date with
respect to the installment then payable.

(d) The Company  shall  deliver to the  Director all of the shares of Stock that
were awarded to the Director as  Restricted  Stock within 30 days  following the
lapse of restrictions as described in Section 7(c).

(e)  Whenever a  fractional  share would  otherwise  be required to be issued in
accordance  with the terms of this  Section  10, the Fair  Market  Value of such
fractional share shall be paid in cash.

11. Payment in the Event of Death.

(a) In  the  event  of a  Director's  death,  any  shares  of  Restricted  Stock
previously  awarded shall vest as described in Section 7(c),  payment of amounts
credited to such Director's  Deferred  Account shall be paid in cash and payment
of Stock  Equivalent  Units shall be made in the form previously  elected by the
Director,  provided  that  if no such  election  had  been  made  prior  to such
Director's  death,  payment  shall be made in  shares  of Stock  except  for any
fractional share the Fair Market Value of which shall be paid in cash.

(b)  Payment  shall be made as soon as  practicable  following  the death of the
Director in a single lump sum to the  beneficiary  designated  in writing by the
Director, of if no designation was made, to the person legally entitled thereto,
as  designated  under  the  will of the  Director,  or to such  heir or heirs as
determined under the laws of intestacy of the Director's domicile.

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

In the  event  that  there is any  change  in the  Stock by  reason of any stock
dividend,  stock split,  combination of shares,  exchange of shares, warrants or
rights  offering  to  purchase  Stock at a price  below its fair  market  value,
reclassification,  recapitalization,  merger,  consolidation,  spin-off or other
change in capitalization, appropriate adjustment shall be made in the number and
kind of shares or other property  subject to the Plan and the number and kind of
shares or other property credited to the Directors under the Plan, and any other
relevant  provisions of the Plan by the Committee,  whose determination shall be
binding and conclusive on all persons.

13. Change in Control.

In the event of a Change  in  Control,  the  following  shall  occur on the date
thereof  (the  "Change in Control  Date"):  (i) the last day of the then current
Plan Year shall be deemed to occur on the Change in Control Date;  (ii) pursuant
to Sections 5, 6, 7 and 8,  Directors  shall be credited  with Stock  Equivalent
Units or awarded shares of Stock, as if for this purpose  Directors'  service as
Directors  ceased on the Change in Control Date;  (iii) Dividend  Equivalents on
Stock  Equivalent  Units and Restricted  Stock,  including  those credited under
clause  (ii),  and  interest  on any  Deferred  Accounts  shall be  credited  in
accordance  with  Section  9;  and (iv) the  Company  shall  pay a lump sum cash
payment in settlement of the amount of cash credited to each Director's Deferred
Account and the number of Stock Equivalent Units then credited to such Director,
including cash and Stock Equivalent Units credited  pursuant to clauses (ii) and
(iii)  above.  For  purposes  of the  preceding  sentence,  the  amount  of cash
delivered in payment of Stock Equivalent Units shall equal such units 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 of Stock  which is paid or offered to be paid,
by any person or entity,  in connection  with the transaction  constituting  the
Change in Control.

14. Rights with respect to Stock Equivalent Units.

Except to the extent  otherwise set forth in the Plan,  Directors shall not have
any of the rights of a shareholder  with respect to the Stock  Equivalent  Units
credited to them.

15. General Restrictions.

(a) No shares of Stock shall be issued under the Plan prior to compliance by the
Company,  to the  satisfaction  of its  counsel,  with any  applicable  law. The
Company  shall not be obligated to, but may in its  discretion,  take any action
under applicable  federal or state law (including  registration or qualification
of the Plan or the Stock) necessary for compliance  therewith in order to permit
the issuance of shares hereunder.

(b) The Company may impose such restrictions on the sale or other disposition of
shares of Stock  issued  under  the Plan as it deems  necessary  to comply  with
applicable securities laws.

16. Withholding.

The  Company may defer  making  payment or delivery of shares of Stock under the
Plan  until  satisfactory  arrangements  have been made for the  payment  of any
Federal,  state or local  income taxes  required to be withheld  with respect to
such payment or delivery,  including  without  limitation by the  withholding of
shares that would  otherwise  be so  delivered,  by  withholding  from any other
payment due to the Director, or by a cash payment to the Company by a Director.

17. No Right to Nomination for Reelection.

Nothing in the Plan shall be deemed to create any  obligation on the part of the
Board to nominate any Director for reelection by the Company's  shareholders  or
to limit the rights of the shareholders to remove any Director.

18. Amendment and Termination of the Plan.

The  Board may at any time  amend or  terminate  the Plan,  in whole or in part,
however,  no amendment or  termination  shall  without the written  consent of a
Director, reduce the Director's rights with respect to awards previously granted
hereunder or any fees  previously  earned the payment of which has been deferred
pursuant to the terms of the Plan.

19. Governing Law.

The Plan and all actions taken  thereunder shall be construed in accordance with
and governed by the laws of the State of Connecticut.
