                   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 or restated 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 June 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 quota share  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 loss  adjustment  expenses,  including legal costs, to defend
         HSBIIC's position. One case is on appeal; the other case is involved in
         both arbitration and litigation  proceedings.  The final hearing in the
         arbitration  proceeding  has  concluded  and the  Company is  currently
         awaiting a decision.  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.

         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 Operations have been restated in compliance with SFAS No.
         128. 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  were  distributed  on  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.  Previously,  the  Company
         reported  EPS of $ 0.76 and $2.35 per  share for the  quarter  and nine
         months ended September 30,1997, respectively .

Net income for the nine months ended September 30, 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 

                                       11

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.
HSB's after-tax  earnings  increased 45.4 percent from the third quarter of 1997
and, excluding the above sales,  increased 26.4 percent in the first nine months
of 1998  compared to 1997 due to improved  engineering  revenues and margins and
higher net realized gains.

Gross earned  premiums grew 40.2 percent in the quarter and 24.4 percent year to
date  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 quota share
reinsurance  arrangements  with ERC,  HSBIIC retains 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, the
unearned insurance  premiums,  the reinsurance assets, and the ceded reinsurance
payables  reflected in the  Consolidated  Statements of Financial  Position have
increased  significantly.  The third  quarter  combined  ratio  improved to 87.9
percent in 1998 from 92.0  percent in 1997 and the year to date  combined  ratio
improved to 88.7 percent in 1998 from 91.3 percent in 1997. Engineering services
revenue  increased  63.0 percent for the third  quarter and 49.6 percent year to
date and margins in this  business  grew to 7.6 percent  from 6.3 percent in the
third quarter of 1997 and to 8.3 percent from 6.5 percent year to date.

The  effective  tax rate on  income  from  continuing  operations  for the third
quarter and year to date were 23.5 percent and 28.2 percent for 1998 compared to
24.4 percent and 25.4 percent for 1997. 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  1998  the  taxes
associated with the sale of IRI contributed to a higher first quarter  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.

</TABLE>

Gross  earned  premiums  in the third  quarter and year to date  increased  40.2
percent and 24.4 percent from the comparable  periods in 1997. This increase was
primarily attributable to the new arrangement with HSB Industrial Risk Insurers.
Gross earned  premiums from IRI increased $ 51.7 million in the third quarter of
1998 and $ 118.4 million year to date 1998 compared to the respective periods in
1997. Gross earned premiums  representing  coverage outside the U.S. for non HSB
Industrial  Risk Insurers  business  increased 11.3 percent in the third quarter
and 6.2 percent  year to date from the  comparable  periods 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.

Increases  in ceded  premium  of 272.9  percent in the third  quarter  and 191.0
percent  year to date  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 

                                       13
<PAGE>


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  declined  from 44.6 percent in the third quarter of 1997 to 44.4
percent in the current quarter and increased from 43.5 percent in the first nine
months of 1997 to 44.6  percent in the first nine  months of 1998.  Year to date
1998 results were impacted by severe ice storms in Canada. In 1997 flood related
losses  impacted the loss ratio.  Gross claims and  adjustment  expenses for the
first nine  months of 1998 and 1997 were $ 478.5  million  and $ 216.6  million,
respectively.  Gross  claims in 1998  include  approximately  $ 130 million from
Hurricane Georges on exposures written by HSB Industrial Risk Insurers. On a net
basis the impact on losses for the third quarter and year was $ 1.7 million. The
significant  increase  in  claims  reserves,  reinsurance  assets  and  unearned
insurance  premium  reserves  from prior years are primarily due to HSBIIC's new
relationship with HSB Industrial Risk Insurers as discussed above.

The expense  ratio  improved to 43.5  percent in the third  quarter of 1998 from
47.4 percent in the third  quarter of 1997 and to 44.1 percent year to date 1998
from 47.8 percent year to date 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  12  percentage  points  year to date.  A portion  of such  ceding
commission is intended to reimburse HSB for the additional costs of managing HSB
Industrial  Risk  Insurers.  Ceding  commissions  should  continue to positively
impact the expense ratio throughout 1998.

HSBIIC completed an acquisition of the monoline boiler and machinery business of
Kemper  Insurance  Companies,  effective  July 1, 1998.  The two companies  also
completed an arrangement  for HSBIIC to reinsure  boiler and machinery  coverage
written  as  part  of  Kemper's  commercial  package  policies.  Kemper's  total
estimated boiler and machinery premiums were $ 80 million in 1997.

In April 1998 HSB acquired  SAI based in Dallas,  Texas.  SAI is an  engineering
management  consulting firm that provides comparative  performance  benchmarking
consulting to the refining,  petro-chemical and power generation industries.  In
1997,  SAI had  gross  sales of $13  million.  SAI  establishes  efficiency  and
productivity  benchmarks  for 80 percent  of the  worldwide  petroleum  refining
industry.  This  acquisition  expands HSB's  engineering  management  consulting
services and benchmarking capability.

Engineering  services revenues  increased $ 9.8 million in the third quarter and
$22.5 million year to date  compared to the same periods in 1997.  The growth in
revenues year to date was primarily due to increases generated by HSBRT as their
revenues  increased 20.2 percent,  HSB-EIL's revenues of $ 7.8 million generated
through recent acquisitions,  SAI revenues of $ 3.7 million, as well as revenues
generated by some recent small  acquisitions.  The improvement in operating gain
from the prior year 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.

On July 1, 1998, HSB purchased  Kemper's ASME inspection  services business that
certifies boiler and pressure vessel  compliance with the codes and standards of
the American Society of Mechanical Engineers. Total estimated 1997 revenues were
approximately $ 7.5 million.

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.

Net  investment  income  for the  third  quarter  and  year  to  date  increased
significantly  compared  to the same  periods in 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  significantly  impacted  in 1998 by call  premiums  on fixed  income
investments.  In the third quarter of 1997 realized gains were reduced by $ 10.1
million and year to date 1997 by $ 29.5  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. These collars were closed out by year end 1997.

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 shareholders 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.


Statement of Comprehensive Income
- ---------------------------------

In addition  to the impact of HSB's  results of  operations,  the  Statement  of
Comprehensive  Income  displays the effects of price movements on HSB's invested
assets.  During  the third  quarter  of 1998 the  stock  market  went  through a
correction,  resulting in HSB's  cumulative  holding  gains  decreasing by $21.9
million as  compared to a gain of $1.0  million in 1997.  Year to date change in
cumulative  holding gains in 1998 was an increase of $5.4 million as compared to
an increase of $14.4 million in 1997.

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.

                                       16

Cash  provided  from  operations  was $ 43.0 million in the first nine months of
1998 compared to $18.2 million for the same period in 1997.  Premiums  collected
increased in the first nine months of 1998  compared to the first nine months of
1997 while claims paid declined.

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 $ 413.3  million at  September  30, 1998  increased  by $ 68.0 million
since December 31, 1997. The increase  primarily  reflects net income of $ 115.9
million  year to date;  offset by common  dividends of $ 35.7 million and common
stock repurchases of $ 27.9 million offset by issuances of $ 23.4 million.

At September  30, 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 September 30, 1998
was $ 3 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 HSBIIC 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  writes  business in European  markets  primarily  through its U.K.
subsidiary, HSB Engineering Insurance Limited. The adoption of a common currency
(the euro) by eleven of the fifteen  member  countries of the European  Union on
January  1,  1999 is not  expected  to  result  in a  substantial  change in the
business or a significant  increase in costs in the short term. In part, this is
due to the fact that much of the business is U.S. dollar denominated.  The UK is
not a first wave euro  country and as such the  primary  impact will be in Spain
and the Irish  Republic.  Over time,  as and if the U.K.  adopts the euro as its
currency  there  may be  more of an  impact,  however  the  number  of  affected
transactions  are such that a manual backup system is  practicable.  The Company
will continue to monitor  developments  and assess impacts on markets,  pricing,
etc.

Year 2000
- ---------

Year 2000 Plan and State of Readiness

In 1996 the Company began a  comprehensive  effort to assess and address  issues
affecting the Company  which related to the inability of computer  equipment and
embedded computer chips to distinguish  between the year 1900 and the year 2000.
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.

As a part of this effort, the Company established a Year 2000 Program to address
four key areas: (i) applications software, primarily consisting of the Company's
policy management,  claims,  financial  recording and reporting,  human resource
systems, and engineering databases and systems;  (ii)  infrastructures,  such as
mainframe and corporate servers, workstations and

                                       17
<PAGE>

networking  components;  (iii)  embedded  technology  in facilities in which the
Company  conducts its operations and in testing  equipment used by the Company's
engineering staff ; and (iv) key business  partners and suppliers.  In addition,
the Company is evaluating  potential  coverage exposures arising out of the Year
2000 and its  impact on  insured  equipment.  The  Company's  Year 2000  Program
consists of six  partially  overlapping  stages for the key areas listed above :
(i) assessment and analysis; (ii) development, renovation and replacement; (iii)
implementation;  (iv) testing and certification;  (v) contingency planning;  and
(vi) audit and review.  The Company is using members of its internal IT staff as
well as  external  consultants  and  programmers  to complete  various  tasks in
connection with its Year 2000 Program and is currently on schedule.

The Company has  completed  the  assessment  and  analysis  phase for its policy
management,  claims, and financial  recording and reporting,  and human resource
systems and  engineering  databases  and  systems.  The Company  expects to have
largely completed the development,  renovation,  replacement and  implementation
phases for all of these  applications  by year-end  1998 with the  exception  of
human  resource and certain  non-critical  financial  reporting and  engineering
systems which are expected to be compliant by mid-1999.

The Company has  completed  the  assessment  and analysis  phase with respect to
infrastructure  items.  The  mainframe  is Year 2000  compliant  and the Company
expects to complete the migration to Year 2000 compliant  servers and supporting
hardware and software by September 1999.  Replacement of the various  components
of non-compliant  workstations  and peripheral  equipment also is expected to be
completed by  September  1999.  Many of the  third-party  software  applications
utilized  by the  Company  in its  desktop  environment  are  already  Year 2000
compliant.  The Company  expects to complete the  installation of such compliant
programs on virtually all of its workstations during the first half of 1999.

In the area of  embedded  chip  technology,  the  Company's  principal  exposure
relates to the  prevalence of such  technology in office  buildings in which the
Company  leases space for conducting  its business  operations.  The Company has
sent  questionnaires to the leasing vendors for all of its principal  facilities
with respect to Year 2000  readiness  and has received  assurances  of readiness
from most of its vendors.

The  Company is  currently  in the process of  identifying  and  contacting  key
suppliers of services and business  partners,  such as client companies,  agents
and brokers,  with whom the company has significant  business  relations and who
may either  electronically  provide to, or receive  from,  the  Company  certain
financial and other  information.  The Company expects to compile the assessment
of the  potential  impact on the  Company  of such  parties'  Year 2000 state of
readiness  and  remediation  plans by the end of the first  quarter  of 1999 and
conduct renovation and/or replacement and compliance testing, as appropriate.

The Company is relying upon Year 2000 readiness statements of other entities and
has not independently verified the accuracy of such statements.

Costs

It is currently  estimated that the Company's  aggregate  spending in connection
with  the  Year  2000  Program  will be in the  range  of $26  million  of which
approximately  $14.9  million has been  expended  through  September  30,  1998.
Certain of these  costs are being  expensed as they are

                                       18
<PAGE>

incurred  and are being  funded  through  operating  cash flow.  The Company has
expensed $.2 million for 1996,  $1.5 million for 1997,  and $3.6 million for the
first nine months of 1998. It is estimated that expenditures of $1.4 million for
the  fourth  quarter  of 1998 and $4.8  million  for 1999  will be  expensed  as
incurred.  The remainder of the $26 million estimate relates to systems that the
Company  anticipated  replacing in the normal course of  information  technology
development but the timetable for which was accelerated in  contemplation of the
Year 2000 event. Costs of replacement and renovation of information  systems and
infrastructure  which  would  have  occurred  in the normal  course of  business
without the advent of Year 2000 are  excluded  from these  amounts.  The current
estimate also does not include any costs associated with the  implementation  of
contingency plans which are in the process of being developed.

The Company does not expect the costs  relating to its Year 2000 program to have
a  material  effect  on  its  results  of  operations,  liquidity  or  financial
condition.  However,  the  Year  2000  Program  is an  ongoing  process  and the
estimated costs, as well as the estimated completion dates for various phases of
the program, are subject to change.

Risks

The failure of one or more critical  software  applications or components of the
Company's  infrastructure  to be Year  2000  compliant  could  cause a  material
disruption in the normal business  operations of the Company.  Such  disruptions
could include the inability to process  policies,  register and collect premiums
and  engineering  receivables,   process  claims  or  schedule  inspections  and
engineering services. Due to the difficulty in estimating the scope and duration
of such  failures,  the Company is unable to  determine at this time whether the
consequences  of such  failures  will have a  material  impact on the  Company's
results  of  operations,   liquidity,  or  financial  condition.  Moreover,  the
Company's  operations are  interdependent  with systems of business partners and
service  providers,  such  as  financial  institutions,   communication  service
providers and utilities,  over which the Company has no control.  The failure of
one or more of such  business  partners  or  service  providers  to be Year 2000
compliant  could have a material  adverse  impact on the Company.  However,  the
Company  believes  that  with the  implementation  of its Year 2000  Program  as
scheduled, including the contingency plans discussed below, the risk of material
disruptions to its normal business operations should be significantly reduced.

As an  insurance  company,  the Company  maintains a  significant  portfolio  of
investments in cash, short-term fixed income, and equity securities. Inasmuch as
the advent of the Year 2000 may cause events, business interruptions and altered
economic facts and circumstances,  the value of the Company's investments may be
affected  favorably or  unfavorably.  The Company is selectively  monitoring the
Year 2000  compliant  status of the corporate  issuers of the  securities in its
investment  portfolio  primarily through reviewing public disclosure  documents.
State government and municipal bonds held by the Company are general obligations
and/or are  credit-enhanced and therefore the Company does not perceive there to
be a  significant  credit risk with these  securities in the absence of a severe
Year  2000  disruption  affecting  governments  and  businesses  generally.   An
immaterial portion of the Company's  portfolio is invested in non-public issuers
where public  disclosure  documents are  unavailable.  Due to the  difficulty in
estimating  the scope and  duration  of such  events,  the  Company is unable to
determine at this time whether the consequences of such developments will have a
material  impact on the Company's  investment  portfolio and  therefore,  on the
Company's results of operations, liquidity or financial condition.

Contingency Plans

As a component of the Year 2000 Program, the Company is concurrently  developing
contingency  plans  intended to mitigate  the  possible  disruption  of business
operations  arising out of the Year 2000 event. These plans will be continuously
refined during 1999 as the Company completes  compliance testing on its internal
applications  software  and  infrastructure  and further  assesses the Year 2000
readiness  status  of its  business  partners.  Contingency  plans  may  include
securing  back-up  power  for the  Company's  data  center,  manual  processing,
short-term  fixes to non-compliant  programs or business partner  interfaces and
modifying the Company's asset selection criteria for its investment activities.

Insurance Coverage Issues

The Company continues to evaluate the potential  coverage  exposures arising out
of the Year 2000 event and its  impact on insured  equipment.  The  Company  has
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. The endorsement is being included in policies in
all states which have approved the endorsement.  In the four jurisdictions which
have not approved the endorsement,  a notice  reiterating the Company's coverage
intent with respect to Year 2000 exposures is being sent to  policyholders.  The
Company  has  recently  filed a similar  endorsement  for use with its  all-risk
policy and expects to receive  approvals  consistent with those received for its
equipment breakdown endorsement. Many of the insurers that the Company reinsures
for  equipment  breakdown  coverage are issuing  similar  endorsements  to their
policies. The Company is conducting an on-going  communications program with its
client company insurers and agents to disseminate to the ultimate  policyholders
its Year 2000 loss control suggestions and policy coverage position.

Quantification of the Company's exposure to Year 2000 losses and loss adjustment
expenses  are not  reasonably  estimable at this time as  applicable  policy and
reinsurance  contract  wordings  have not been legally  tested in the context of
such losses.

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

                                       20
<PAGE>

Company,  whether resulting from changes in the law or otherwise; the ability of
the Company and key  suppliers and business  partners to  adequately  and timely
address  issues  relating  to the Year  2000  event;  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 loss  adjustment  expenses,  including  legal costs to defend
         HSBIIC's position. One case is on appeal; the other case is involved in
         both arbitration and litigation  proceedings.  The final hearing in the
         arbitration  proceeding has been concluded and the Company is currently
         awaiting a decision.  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.

         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.

                       HSB INDUSTRIAL RISK INSURERS, L.LC.

THIS LIMITED LIABILITY  COMPANY  AGREEMENT  ("Agreement") of HSB Industrial Risk
Insurers,  L.L.C. (the "Company") dated as of  _____________________________  is
between Employers Reinsurance Corporation ("ERC"), a Missouri corporation,  with
principal offices at 5200 Metcalf,  Overland Park, Kansas and The Hartford Steam
Boiler Inspection and Insurance  Company ("HSB"),  with principal offices at One

          be  conducted  by a Board of Managers  (collectively,  "the Board" and
          individually,  a  "Manager")  which  will be  responsible  for all the
          business and affairs of the 
<PAGE>

          Company.  Members  acting as Managers shall do so in their capacity as
          Members and each Member-Manager  shall be an agent of the Company. The
          power to act for or bind the Company  shall be vested  exclusively  in
          the Board.  The Board of Managers  may delegate  its  authorities  and
          responsibilities for management of the business affairs of the Company
          to third parties,  but such delegation  shall not relieve the Board of
          any of its  obligations  under  this  Agreement.  With  respect to the
          HSB-IRI  Business,   the  Members  expressly  delegate  to  HSB  those
          authorities and responsibilities set forth in the Operating Agreement.
          Except as  otherwise  provided  in this  Agreement  or in the  Related
          Agreements,  no Member  shall  have any  authority  to act for,  or to
          assume any  obligations  or  responsibilities  on behalf of, any other
          Member.

     (b)  Subject to obtaining  any  necessary  approvals  hereunder,  the Board
          shall have the power and  authority to execute and deliver  contracts,
          instruments,  certificates,  filings,  notices or other  documents  on
          behalf of the Company,  including  any  document  required to be filed
          pursuant  to the  Connecticut  Act.  Except as  otherwise  required by
          applicable  law, any such document shall require the signature of only
          one Manager.

     (c)  The number of Managers  on the Board of  Managers  shall be seven (7).
          Until  another  Member  is  admitted,  the Board of  Managers  will be
          comprised as follows:  four (4)  Managers  will be  designated  by ERC
          (each an "ERC  Designated  Manager")  and three (3)  Managers  will be
          designated  by HSB (each an "HSB  Designated  Manager").  All Managers
          shall serve at the pleasure of the Member which  designated  them. The
          Managers  designated by the Initial  Members are listed on Schedule II
          which shall be amended  upon the  admission of another  Member  and/or

          and all HSB  Designated  Managers  shall be employees of HSB or one of
          its  Affiliates.  The number of Managers may be increased or decreased

          relative  proportion  of  ERC  and  HSB  Designated  Managers  remains
          constant,  until such time that any new  Members  are  admitted to the
          Company.  The number of  Managers  shall never be less than three (3).
          Except as otherwise  provided herein,  decisions of the Board shall be
          made  by an  affirmative  vote  of not  less  than a  majority  of the
          Managers.

     (d)  Any Manager shall  continue to serve in such capacity until the Member
          appointing  such  Manager  shall have  notified  the other  Members in
          writing of his  replacement.  In the event of the death or resignation
          of a Manager,  the Member who  appointed  that  Manager  shall elect a
          successor within thirty (30) days.


     (e)  A Member  may,  by written  notice to the other  Members,  designate a
          person  to serve as an  Alternate  for a  Manager  designated  by such

          of the Manager for whom he has been

     required by this  Agreement.  If there are not enough Members  present at a
     meeting  in person or by proxy to  constitute  a quorum,  the  holders of a
     Majority in  Interest  of the Members  present may adjourn the meeting to a
     specified date not longer than thirty (30) days after the  adjournment.  An
     additional  notice  regarding the rescheduled  meeting shall be sent to all
     Members. If a quorum is present at the rescheduled meeting, the Members may
     transact any business which was to be transacted at the adjourned  meeting.
     At each meeting,  the appointed  Secretary shall furnish a complete list of
     the  Members  present  at the  meeting  in  person  or by proxy  and  their
     respective Percentage Interest in the Company.

     business to be performed  by the Board  pursuant to this  Agreement  may be
     transacted at any special or regular Board meeting;  provided however, that
     if at least one  Manager  designated  by each Member is not present at such
     meeting, only such business as set forth in the notice for such meeting may
     be  considered  and  voted  upon.  A  majority  of the  full  Board as then
     presently  existing  shall  constitute  a  quorum  for the  transaction  of
     business,  but if at any  meeting of the Board  there is less than a quorum
     present, a majority of those present may adjourn the meeting and reschedule
     the meeting for a date when a quorum is present.

     Each Manager may bring one or more other advisors to any meeting,  provided
     that such advisors  shall not have the right to vote on any matter  brought
     before the Board of Managers; and provided further, that the Managers shall
     have the right to call  executive  sessions of the Board and to exclude any
     person not a Manager from such executive session.

<PAGE>

     (a)  If at some future date,  one or both of the Initial  Members desire to
          integrate,  combine,  or  incorporate  the  HSB-IRI  Business,  or any
          portion  thereof,  with  blended  products  (e.g.  property  insurance
          combined with one or more other coverages, such as casualty or workers
          compensation, or with financial products) the Initial Members agree to
          preserve the rights and  opportunities  to which HSB is entitled  with
          respect to the HSB IRI Business under the Operating  Agreement and the
          Reinsurance   Agreements   in  any  such  blended   product   business

     (b)  In the event that  substantial  and  materially  adverse  developments
          threaten to frustrate the commercial viability of the HSB-IRI Business
          as structured,  ERC and HSB agree to initiate  discussions  leading to
          modification  of this Agreement and the Related  Agreements.  Any such
          modifications  shall preserve,  to the greatest extent  possible,  the
          rights,  obligations  and  opportunities  to  which  the  parties  are
          entitled under this Agreement and the Related Agreements.

                                   ARTICLE IV

4.1. Capital Contributions.

     The Initial  Members have  contributed to the Company the property and cash
     set forth in Schedule I hereto.  Persons or entities  hereafter admitted as
     Members of the Company shall make such contributions of cash (or promissory
     obligations), property or services to the Company as shall be determined by
     the Members, acting unanimously, at the time of each such admission. Except
     as  otherwise  agreed by all  Members,  the  Initial  Members and any other
     Member shall have no  obligation to make any capital  contributions  beyond
     their initial capital contribution to the Company.

4.2. Future Financing of the Company.

     The Company  may  require  additional  funds for  capital  expenditures  or
     working capital  requirements in the future and any such additional funding
     shall be obtained  from any of the  following  sources as the Members shall
     unanimously  agree: (a) cash reserves of the Company;  (b) loans from banks
     or other financial institutions;  (c) additional Capital Contributions made
     to the Company by the Members in proportion to their  Percentage  Interests
     in amounts to be determined  by the Members;  (d) loans made to the Company
     by  Members  and/or  related  companies  of the  Members;  or (e) any other
     funding source agreed upon by the Members.

4.3. Capital Accounts.

     (a)  A  single,  separate  capital  account  shall be  maintained  for each
          Member.  Each  Member's  capital  account  shall be credited  with the
          amount  of money and the fair 
<PAGE>

          market  value of  property  (net of any  liabilities  secured  by such
          contributed  property  that the Company  assumes or takes  subject to)
          contributed  by that Member to the Company;  the amount of any Company
          liabilities  assumed by such Member (other than in  connection  with a
          distribution of Company property) and such Member's distributive share
          of Company profits  (including tax exempt income) as determined by the
          Member's Percentage  Interest.  Each Member's capital account shall be
          debited with the amount of money and the fair market value of property
          (net of any liabilities  that such Member assumes or takes subject to)
          distributed  to such  Member;  the amount of any  liabilities  of such
          Member  assumed  by the  Company  (other  than  in  connection  with a
          contribution);  and such Member's distributive share of Company losses
          (including  items that may be neither  deducted  nor  capitalized  for
          federal income tax purposes) as determined by the Member's  Percentage
          Interest.

     (b)  The capital  accounts  shall be maintained  and adjusted in accordance
          with  the  Internal  Revenue  Code,  Section  704(b)  and  (c) and the
          Regulations  (1.704-1(b)).  In the  event  the  Members  or the  Board
          determine that it is prudent to modify the manner in which the capital
          accounts  or any debits or credits  thereto  are  computed in order to
          comply  with such laws and  regulations,  the Members or the Board may
          make  such  modification,  provided  that it is not  likely  to have a
          material  effect  on  the  amounts  distributed  to  any  Member  upon
          dissolution as provided herein.

     (c)  Any Member,  including  any  substitute  Member,  who shall receive an
          Interest (or whose Interest shall be increased) by means of a transfer
          to it of all or a part of the Interest of another Member, shall have a
          capital account that reflects the capital account  associated with the
          transferred Interest.

4.4  Expenses of the Company.

     All of the  Company  expenses  shall be billed  directly to and paid by the
     Company.  The Company is specifically  authorized to make reimbursements to
     any Member that  provides  goods,  materials or services used for or by the
     Company  provided  such are  authorized  in  advance in writing or are paid
     pursuant to a written agreement approved by the Members.  In no event shall
     any amount charged to the Company as a  reimbursable  expense by any Member
     exceed the amount that the Company would be required to pay to  independent
     parties for comparable goods, materials or services.

4.5. Distributions.

     Distributions  of cash or other assets of the Company shall be made at such
     times  and in such  amounts  as the  Members  may  determine,  except  that
     distributions  shall be routinely made at each year-end  unless the Members
     determine it would not be prudent to do so.  Distributions shall be made to
     (and  profits  and losses  shall be  allocated  among)  Members pro rata in
     accordance with their respective Percentage Interests.

          including the  amendment to this  Agreement and the execution of other
          documents,  as may be required in order for the Company to qualify for

          purposes.

     (c)  All items of Company income, gain, loss, deduction, credit or the like

          respective Percentage Interest as set forth in Schedule I.

     (d)  Each of the Members shall execute or cause to be executed from time to
          time all other instruments,  certificates,  notices and documents, and

     responsible  for preparing the same,  at reasonable  times during  business
     hours and upon reasonable notice.

5.3  Reports to Members.

     The Members  Committee shall provide or shall cause to be provided to, each
     Member  such  financial  reports and  statement  in such form and with such

                              MEMBERS; DISSOLUTION

     No Member  may sell,  assign,  pledge or  otherwise  transfer  or  encumber
     (collectively  "transfer")  all or any part of its Interest in the Company,
     and no  transferee  of all or any part of the Interest of a Member shall be
     admitted as a substitute Member,  without having obtained the prior written
     consent of at least Two-Thirds in Interest of the non-transferring Members,
     or in the event that there are less than three members,  the consent of the
     non-transferring  Member.  In no  event  shall  a  transfer  of a  Member's
     Interest  include an assignment or transfer of the right to  participate in
     the  management  and affairs of the  Company or to become or  exercise  any
     rights of a Member.  Until the  assignee of a Member's  Interest  becomes a
     Member  upon the  consent of  Members  as  described  above,  the  assignor
     continues to be a Member and have all the powers  attendant  to  membership
     provided  herein.  The Members  shall amend  Schedule I hereto from time to
     time to  reflect  transfers  made in  accordance  herewith.  Any  purported
     transfer in violation of this Section  shall be null and void and shall not
     be recognized by the Company.

6.2  Buy-Out Rights.


     (a)  For a period of 180 days  following the effective  date of a Change in
          Control of HSB,  ERC shall  have the right to  purchase  HSB's  Member
          Interest in the  Company at a price  equal to X times Y (the  "Buy-Out
          Price") where:

          X = the total Pre-Tax  Earnings (as defined  herein) earned by HSB for
          the four calendar quarters immediately  preceding the calendar quarter
          within which the Announcement Date occurs; and

          Y = closing price of HSB Group, Inc. common stock on the day preceding
          the  Announcement  Date divided by the  aggregate net income per share
          for the previous four  quarters;  provided that in no event shall Y be
          less than 10 or more than 15.

          "Pre-Tax  Earnings"  for the purpose of  computing  the Buy-Out  Price
          shall be the sum of :
<PAGE>

          (i) the net amount of ceding commission earned by HSB after performing
          the calculation under Paragraph 7.3 of the Operating  Agreement,  less
          Operating Costs as defined in the Operating Agreement;

          (ii) the  underwriting  income  of HSB ( which  for  purposes  of this
          formula  will not be less  than  zero) on a GAAP  basis  earned by HSB
          under the Reinsurance  Agreements,  after giving effect to any Outward
          Reinsurance  ceded in accordance  with  Paragraph 4.2 of the Operating
          Agreement; and

          (iii) an allocable portion of HSB's investment income  attributable to
          the cash held by IRI in connection with (i) and (ii).

     (b)  In order to  exercise  such right,  ERC must  deliver  written  notice
          relating thereto to HSB within the 180 day period following the Change
          in  Control to HSB,  and within  thirty  (30) days of  receiving  such
          notice,  HSB shall  send a notice  to ERC  setting  forth the  Buy-Out
          Price.  Within  fifteen  (15)  days of  receiving  such  notice of the
          Buy-Out  Price,  ERC shall  send a notice to HSB  stating  that it has
          either  decided to (i) purchase  HSB's Member  Interest at the Buy-Out
          Price (a  "Buy-out  Acceptance  Notice")  or (ii) not  purchase  HSB's
          Member  Interest.  In the event  that ERC  fails to give  such  notice
          within  such  fifteen  (15) day  period,  ERC  shall be deemed to have
          elected not to purchase HSB's Member Interest.

     (c)  A purchase and sale of HSB's Member Interest  pursuant to this Section
          6.2, shall take place at the office of the Company on such date within
          thirty  (30) days of the date of  delivery  of the  Buyout  Acceptance
          Notice as specified by ERC (subject to extension if required to obtain
          any  regulatory   approvals  and  to  permit  the  expiration  of  any
          applicable statutory waiting periods).

     (d)  ERC may assign its right to purchase HSB's Member  Interests  pursuant
          to this Section 6.2 to any of its Affiliates.

     (e)  On the closing date of any purchase of HSB's Member Interest  pursuant
          to this Section  6.2,  the  Operating  Agreement  shall be  considered
          terminated  without  any  further  action  required on the part of the
          parties thereto to effect such termination.


6.3  Withdrawal of Members.

     No Member shall have the right to withdraw from the Company except with the
     consent of  two-thirds  in Interest of all other  Members,  or in the event
     that  there  are less  than  three  Members  at the  time of such  proposed
     withdrawal,  with the consent of the remaining Member,  and upon such terms
     and  conditions  as may be  specifically  agreed  upon  between  such other
     Members  and the  withdrawing  Member.  The  withdrawing  Member  shall  be
     entitled  to receive  any  distribution  which the Member was  entitled  to
     receive  prior  to  the  withdrawal.  Unless  otherwise  agreed  to by  the
     remaining Members,  the 
<PAGE>

     withdrawing  Member  shall not be  entitled  to  payment  for the  Member's
     Interest in the  Company  and,  beginning  on the date of  withdrawal,  the
     withdrawing Member shall no longer be a Member of the Company.

     shall be dissolved and its affairs wound up and  terminated  upon the first
     to occur of the following:

     (c)  the occurrence of any event that makes it unlawful for the business of
          the  Company to be  carried on or for the  Members to carry it on as a
          limited liability company.

6.6. Continuation of the Company.

     not be  dissolved  if within  ninety (90) days after the  occurrence  of an

          the Board of Managers, or any committee thereof, against any liability
          to the  Company  or the  Members to which  such  Member or  non-Member
          Manager  would  otherwise  be  subject  by reason  of:  (i) any act or
          omission  of such  Member  or Person  that  involves  actual  fraud or
          willful  misconduct or (ii) any transaction  from which such Member or
          Person derived improper personal benefit.
<PAGE>

     (b)  The  Company  shall  indemnify  and  hold  harmless  each  Member  and
          non-Member   Manager  and  the  affiliates  of  any  Member  (each  an
          "Indemnified  Party")  against  any and all losses,  claims,  damages,
          expenses  and  liabilities   (including,   but  not  limited  to,  any
          investigation,   attorneys'  fees,   expert  witness  fees  and  other
          reasonable  expenses incurred in connection with, and any amounts paid
          in settlement of, any action,  suits,  proceedings,  or claims) of any
          kind or nature  whatsoever that such Indemnified Party may at any time
          become subject to or liable for by reason of the formation,  operation
          or termination of the Company or the  Indemnified  Party's  actions in
          connection with the conduct of the affairs of the Company  (including,
          without  limitation,   indemnification   against   negligence,   gross
          negligence or breach of duty); provided,  however, that no Indemnified
          Party shall be entitled to  indemnification  if and to the extent that
          the liability otherwise to be indemnified for results from (i) any act
          or omission of such  Indemnified  Party that involves  actual fraud or
          willful misconduct or (ii) any transaction from which such Indemnified
          Party derives  improper  personal  benefit.  The indemnities  provided
          hereunder shall survive termination of the Company and this Agreement.
          Each  Indemnified  Party shall have a claim  against the  property and
          assets  of the  Company  for  payment  of any  indemnity  amounts  due
          hereunder,  which amounts shall be paid or properly reserved for prior
          to the making of  distributions  by the Company to Members.  Costs and
          expenses that are subject to  indemnification  hereunder shall, at the
          request of the Indemnified  Party, be advanced by the Company to or on
          behalf  of such  Indemnified  Party  prior  to final  resolution  of a
          matter,  so long as such  Indemnified  Party shall have  provided  the
          Company with a written  undertaking  to reimburse  the Company for all
          amounts  so  advanced  if  it  is  ultimately   determined   that  the
          Indemnified Party is not entitled to indemnification hereunder.

     (c)  The  contract  rights to  indemnification  and to the  advancement  of
          expenses  conferred  in this Section 8.2 shall not be exclusive of any
          other  right that any party may have or  hereafter  acquire  under any
          statute, agreement, vote of the Members or otherwise.

     (d)  The Company may maintain insurance,  at its expense, to protect itself
          and any  Member or  non-Member  Manager  of the  Company,  or  another
          limited liability company,  corporation,  partnership,  joint venture,
          trust or other  enterprise  against any  expense,  liability  or loss,
          whether  or not the  Company  would have the power to  indemnify  such
          party  against such expense,  liability or loss under the  Connecticut
          Act.

     (e)  The  Company  may, to the extent  authorized  from time to time by the
          Members,  grant  rights  to  indemnification  and  to  advancement  of
          expenses to any employee or agent of the Company to the fullest extent
          of the provisions of this Section with respect to the  indemnification
          and advancement of expenses of Members and non-Member  Managers of the
          Company.

                             1985 STOCK OPTION PLAN


                 ARTICLE I - PLAN ADMINISTRATION AND ELIGIBILITY

1.1  Purpose

     The purpose of the 1985 Stock Option Plan is to attract and retain  persons
     of ability as employees of the Company and its Subsidiaries and 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  stockholders.  The Plan has been amended and
     restated,  effective  January 1,  1987,  to  provide  for the  payment of a
     Related Tax Benefit upon the exercise of certain  options and for awards of
     Restricted Stock.

1.2  Definitions

     (a)  "Appreciation"  shall  mean the excess of the Fair  Market  Value of a
          share over the option price per share specified in an option agreement
          multiplied  by the  number of shares  subject to the option or portion
          thereof which is surrendered.

     (b)  "Affiliate" shall have the meaning set forth in Rule 12b-2 promulgated
          under Section 12 of the Exchange Act.

     (c)  "Beneficial  Owner"  shall  have the  meaning  set forth in Rule 13d-3
          under the Exchange Act.

     (d)  "Beneficiary"  shall mean the legal  representative of the estate of a
          deceased Optionee or the person or persons who shall acquire the right
          to  exercise  an  option or Stock  Appreciation  Right by  bequest  or
          inheritance  or by reason of the  death of the  Optionee.  In the case
          where a  Participant's  right to shares of  Restricted  Stock  vest as
          provided in Section 2.6(d) on or prior to his date of death,  the term
          "Beneficiary"  shall also mean the legal  representative of the estate
          of the  Participant  or the person or persons  who shall  acquire  the
          right to such vested shares of Stock

               acquired   directly   from  the   Company   or  its   affiliates)
               representing  25% or more of the  combined  voting  power  of the
               Company's then outstanding  securities,  excluding any Person who
               becomes such a Beneficial  Owner in connection with a transaction
               described in clause (i) of paragraph (III) below; or

               (II) the following individuals cease for any reason to constitute

               appointment,  election or nomination  for election was previously
               so approved or recommended; or

               Company or any direct or indirect  subsidiary of the Company with
               any other  corporation,  other than (i) a merger or consolidation
               which  would  result  in the  voting  securities  of the  Company
               outstanding  immediately  prior to such  merger or  consolidation

               of the Company or any subsidiary of the Company,  at least 60% of
               the  combined  voting power of the  securities  of the Company or
               such  surviving   entity  or  any  parent   thereof   outstanding
               immediately after such merger or consolidation,  or (ii) a merger
               or consolidation  effected to implement a recapitalization of the

               the Company (not including in the securities  Beneficially  Owned
               by such Person any securities  acquired directly from the Company
               or its  Affiliates)  representing  25% or  more  of the  combined
               voting power of the Company's then outstanding securities; or

               (IV) the  shareholders  of the Company approve a plan of complete
               liquidation or dissolution of the Company or there is consummated
               an agreement for the sale or disposition by the Company of all or

               voting  power of the  voting  securities  of which  are  owned by
               shareholders of the Company in substantially the same proportions
               as their ownership of the Company immediately prior to such sale.

          Notwithstanding  the  foregoing,  a "Change in  Control"  shall not be
          deemed  to  have  occurred  by  virtue  of  the  consummation  of  any

          immediately  prior  to such  transaction  or  series  of  transactions
          continue to have substantially the same proportionate  ownership in an
          entity  which  owns  all or  substantially  all of the  assets  of the

          subject to a Related Tax Benefit, of an amount, computed in accordance
          with the  following  formula  where X equals the lower of the  percent
          established  by the  Committee at the time of grant of the Related Tax
          Benefit,  or the highest  marginal rate imposed under Section 1 of the
          Code for the taxable year in which the exercise occurs:

          (i)  X percent of the excess of the Fair Market  Value of one share of
               Stock over the  respective  option price per share  multiplied by
               the number of whole and fractional shares of Stock distributed by
               the Company to the  Optionee  with  respect to such an  exercised
               option or portion of such an option,  the Fair Market Value to be

          Stock (valued at current Fair Market  Value) or a combination  thereof
          having an  aggregate  value  equal to the excess of the  current  Fair
          Market  Value of one (1) share over the option  price of one (1) share

     promulgated  under the  Exchange Act and an "outside  director"  within the
     meaning  of  Section  162(m)  of the Code.  The  Committee  shall  have the
     responsibility  of interpreting the Plan and establishing and amending such
     rules and regulations  necessary or appropriate for the  administration  of
     the Plan or for the continued  qualification of any Incentive Stock Options
     granted hereunder.  In addition,  the Committee shall have the authority to
     designate the employees who shall be granted options and awarded Restricted
     Stock  under the Plan and the  amount and  nature of the  options,  related
     rights and awards to be granted to each such employee.  All interpretations
     of the Plan or of any  options,  related  rights or awards  issued under it
     made by the Committee or any  subcommittee  shall be final and binding upon
     all  persons  having an interest  in the Plan.  No member of the  Committee
     shall be liable for any action or determination taken or made in good faith
     with respect to this Plan or any option granted hereunder.

1.4  Eligibility

     Executive   and  middle   management   employees  of  the  Company  or  its

<PAGE>


1.5  Stock Subject to the Plan

     (a)  The maximum  number of shares  which may be optioned or awarded  under
          the Plan shall be 2,600,000  shares of Stock.  Preferred  Stock may be
          used in lieu of grants  of Stock  under the Plan  subject  to  further
          authorization  of the  Board of the  Company.  The  limitation  on the
          number of shares which may be optioned or awarded under the Plan shall
          be subject to adjustment under Section 3.2 of this Plan.

     (b)  If any  outstanding  option  under  the Plan for any  reason  expires,
          lapses or is terminated, the shares of the Stock which were subject to
          such option shall be restored to the total number of shares  available
          for  grant  pursuant  to the  Plan.  Shares  as to  which  there  is a
          surrender  in whole or in part of an  option  upon the  exercise  of a
          Stock  Appreciation  Right  shall  not  again be  available  for grant
          pursuant to the Plan.  Stock  delivered  upon the  exercise of a Stock
          Appreciation  Right shall not be charged  against the number of shares
          of Stock available for the grant of options.

     (c)  Upon the  exercise  of an option  or a Stock  Appreciation  Right,  or
          payment of a Restricted  Stock award, the Company may distribute newly
          issued  shares  or  shares  previously  repurchased  on  behalf of the
          Company through a broker or other  independent agent designated by the
          Committee.  Such  repurchases  shall  be  subject  to such  rules  and
          procedures  as the  Committee  may  establish  hereunder  and shall be
          consistent with such conditions as may be prescribed from time to time
          by law or by the  Securities  and Exchange  Commission  ("SEC") in any
          rule or  regulation  or in any  exemptive  order or  no-action  letter
          issued by the SEC to the  Company  or the broker  with  respect to the
          making of such purchase or otherwise.

ARTICLE  II - OPTIONS,  RELATED  TAX  BENEFITS,  STOCK  APPRECIATION  RIGHTS AND
RESTRICTED STOCK

2.1  Granting of Options

     The Committee may grant Incentive Stock Options (ISOs),  Nonstatutory Stock
     Options or any combination thereof, provided that the aggregate Fair Market
     Value (determined at the time the option is granted) of the shares of Stock
     with  respect  to  which  ISOs are  exercisable  for the  first  time by an
     employee  during any  calendar  year (under this Plan and any other  option
     plan of the Company or its Subsidiaries) shall not exceed $100,000. No such
     maximum limitation shall apply to Nonstatutory Stock Options.

2.2  Terms and Conditions of Options

     Each option granted under the Plan shall be authorized by the Committee and
     shall be  evidenced  by a  written  agreement,  in a form  approved  by the
     Committee,  containing  the following  terms and  conditions and such other
     terms and conditions as the Committee may deem appropriate:

     (a)  Option Term - Each option  agreement  shall specify the term for which
          the option  thereunder  is granted and shall  provide  that the option
          shall expire at the end of such term.  In no event shall any option be
          exercisable  any  earlier  than one year after the date of such grant.
          The Committee  shall have  authority to grant options  exercisable  in
          cumulative  or  non-cumulative   installments.   No  option  shall  be
          exercisable after the expiration of ten years from the date upon which
          such  option is  granted.  Notwithstanding  anything  to the  contrary
          contained herein, in the event of a Change in Control, all outstanding
          options shall immediately become exercisable.

     (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 proper  written  notice to the
               Company or its duly  authorized  agent  accompanied by the proper
               amount of payment  for the  shares,  as  provided  under  Section
               2.2(d) hereunder.
<PAGE>

          (2)  No ISO granted prior to January 1, 1987 shall be exercised  while
               there is  outstanding  any other ISO  previously  granted  to the
               employee,  pursuant  to the Plan or any other plan of the Company
               or any Subsidiary (or a predecessor of any such  corporations) to
               purchase  shares  of Stock or  stock  of any  Subsidiary  (or any
               predecessor  of any  such  corporations).  For  purposes  of this
               section, an ISO shall be treated as outstanding until such option
               is  exercised  in full or expires by reason of the lapse of time.
               An ISO shall be  considered  exercised  in full when  either  the
               underlying  option or the  related  Stock  Appreciation  Right is
               exercised.

          (3)  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 agreement 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.

          (4)  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  
<PAGE>

               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 or if  permitted by the  Committee,  by tendering
               shares of Stock of the  Company  (by either  actual  delivery  of
               shares or by attestation,  with such shares valued at Fair Market
               Value as of the day of  exercise)  held by the  purchaser  for at
               least six months; or in any combination thereof, as determined by
               the Committee; or

          (2)  if  permitted  by the  Committee,  a  Participant  may  elect  to
               authorize a third party to sell shares of Stock (or a  sufficient
               portion of the shares)  acquired  upon exercise of the option and
               remit to the Company a sufficient  portion of the sales  proceeds
               to  pay  the  entire  exercise  price  and  any  tax  withholding
               resulting from such exercise.

     (e)  Nontransferability  - No option or Stock  Appreciation  Right  granted
          under the Plan shall be transferable other than by will or by the laws
          of descent and distribution  subject to Section 2.5 hereunder.  During
          the lifetime of an  Optionee,  an option or Stock  Appreciation  Right
          shall be exercisable only by such Optionee.

     (f)  Laws and Regulations - The Committee shall have the right to condition
          any  issuance of shares to any  Optionee or  Participant  hereunder on
          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
          payment of a Related  Tax  Benefit or the lapse of  restrictions  with
          respect to Restricted Stock awarded to a Participant under the
<PAGE>

          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
          agreement  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  agreement  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  agreement that materially
          increases the value of the option agreement to the Optionee.

2.3  Related Tax Benefit

     (a)  The  Committee  may, but shall not be required to designate an option,
          either at date of grant of a Nonstatutory  Stock Option or thereafter,
          as being subject to a Related Tax Benefit. A Related Tax Benefit shall
          be payable to the  Optionee  only upon the exercise of the option with
          which it is  associated  and payment shall be made at the time of such
          exercise.  The  conditions  and  limitations  of a Related Tax Benefit
          shall be determined by the Committee and the Committee  shall have the
          authority to amend the formula set forth in Subsection  (s) of Section
          1.2 at any time without the consent of the Optionee.

     (b)  On and after  January 1, 1987,  an Optionee  may,  with respect to any
          unexercised Incentive Stock Option, apply to the Committee to elect to
          convert,  at  the  discretion  of  the  Committee,  such  option  to a
<PAGE>
          
          Nonstatutory  Stock  Option.  The  Committee  may,  but  shall  not be
          required to, approve such  conversion to a Nonstatutory  Stock Option.
          Effective  upon  approval of such  conversion  by the  Committee,  the
          option that was an Incentive  Stock  Option  prior to such  conversion
          shall cease to be an option  described in Section 422A of the Code and
          shall be deemed  to be a  Nonstatutory  Stock  Option.  Following  the
          approval of such conversion, the Committee may, in accordance with the
          provisions of Section 2.3(a), designate such Nonstatutory Stock Option
          as being  subject  to a Related  Tax  Benefit in  accordance  with the
          provisions of this Section 2.3.

     (c)  A Related Tax Benefit  shall be payable in cash or, at the  discretion
          of the  Committee,  in Stock or a  combination  of cash and Stock such
          that the sum of the amount of cash,  if any, and the Fair Market Value
          of the Stock (as of the date of  exercise)  is equal to the  amount of
          such Related Tax Benefit.  Payment of any Related Tax Benefit shall be
          subject to the provisions of Section 2.2(f)  respecting the payment of
          taxes which the Company or Subsidiary is required to withhold.

2.4  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  agreement  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
          agreement  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
<PAGE>

               (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 him
          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.

2.5  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 option  agreement of such Optionee
          provides otherwise. The conditions established by the Committee in the
          agreement  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.
<PAGE>

          (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 in the option agreement.

2.6  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).
<PAGE>

     (b)  Upon the award to a Participant of shares of Restricted Stock pursuant
          to Section 2.6(a), the Participant shall, subject to Subsection (c) of
          this Section 2.6,  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  2.6(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
          2.6(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  2.6(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  
<PAGE>

          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.

                        ARTICLE III - GENERAL PROVISIONS

3.1  Authority

     Appropriate  officers  of  the  Company  designated  by the  Committee  are
     authorized  to  execute  and  deliver  option  agreements,  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
     agreements  and the  purchase  price per share  thereof  and the  number of
     shares of Restricted  Stock awarded pursuant to Section 2.6(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.
<PAGE>

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 stockholder  with respect to any shares
     subject to his 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  stockholder  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 the approval of the holders of a
     majority  of the  outstanding  shares  entitled  to  vote,  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.

     such Director's termination.


7.   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 7, 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  Deferred  Shares in
          accordance  with  subsection (b) below;  or (ii) 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 7 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  Deferred  Shares will be
          credited  as of the last  day of the Plan  Year  with  the  number  of
          Deferred Share units, including fractional Deferred Share 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.


8.   Dividend  Equivalents  Payable  on  Deferred  Shares and  Interest  Paid on
     Deferred Cash Accounts.

     (a)  Dividend  Equivalents  shall be credited  on  Deferred  Shares held by
          Directors  based upon  dividends  paid on shares of Stock  between the
          date such Deferred  Shares 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 Deferred  Shares  following the
          end of a Plan Year based on the number of Deferred  Shares credited to
          a Director's  account as of the dividend  record dates falling  within
          such Plan Year multiplied by the Dividend  Equivalent amount 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 Deferred Shares 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 Deferred Shares 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 Deferred  Shares to which they relate are credited to the Director
          in accordance with Section 6.

     (d)  Dividend  Equivalents  will be payable  on  Deferred  Shares  credited
          pursuant to a Deferral  Election  pursuant to Section 7 in  accordance
          with  subsections (a) and (b) above as though such Deferred Shares 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 Deferred Shares to which they relate are
          credited to the Director in accordance with Section 7.

     (e)  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 8.5% shall
          be credited to each Deferred Account on the average daily balance held
          in such accounts for the preceding Plan Year or portion thereof.


9.   Time and Form of Payment.

     (a)  Payment in  settlement  of Deferred  Shares 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 Deferred  Shares 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 in the form of cash shall be paid
          out in cash and Deferred Shares held by a Director shall be paid in an
          equivalent number of shares of Stock.


     (d)  Whenever a fractional  share would  otherwise be required to be issued
          in accordance  with the terms of this Section 9, the Fair Market Value
          of such fractional share shall be paid in cash.


10.  Payment in the Event of Death.

     (a)  In the event of a  Director's  death,  payment of amounts  credited to
          such Director's  Deferred Account shall be paid in cash and payment of
          Deferred  Shares  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

          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

          the Committee.

          Participant for any Performance Period shall not exceed $2 million.

          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.

          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.
<PAGE>

     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

     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

          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,

          the Company.

          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

     (b)  A Participant whose employment terminates by dismissal with or without
          cause, or who voluntarily  terminates employment without consent prior

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

          Participant's death.

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, provided that the Committee may not, without shareholder
          approval,  take any of the following  actions unless such actions fall
          within the  provisions  of  Section 9 of the Plan:  (i)  increase  the
          number of Shares reserved for delivery under the Plan; (ii) change the
          class  of  persons  eligible  to  participate  in the  Plan;  or (iii)
          increase the maximum  amount of awards to be made to  Participants  as
          determined  pursuant to Section  7(d) of the Plan;  and 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

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
<PAGE>

          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  
<PAGE>

     termination  date, but awards made prior to its termination date may extend
     beyond that date.

          surrendered.

          the Plan shall be 2,775,000  shares of Stock.  Preferred  Stock may be
          used in lieu of grants  of Stock  under the Plan  subject  to  further
          authorization  of  the  Board  of  the  Company.  Notwithstanding  the
          foregoing,  in no event  shall the  Committee  grant  any  Participant
          Incentive   Stock   Options,   Nonstatutory   Stock   Options,   Stock
          Appreciation  Rights or Restricted  Stock in any single  calendar year
          for more than 150,000 shares of Stock. The limitation on the number of
          shares  which  may be  optioned  or  awarded  under  the Plan or to an
          individual  Participant  shall be subject to adjustment  under Section
          3.2 of this Plan.
<PAGE>

     (b)  If any  outstanding  option  under  the Plan for any  reason  expires,
          lapses or is terminated, the shares of the Stock which were subject to
          such option shall be restored to the total number of shares  available
          for  grant  pursuant  to the  Plan.  Shares  as to  which  there  is a
          surrender  in whole or in part of an  option  upon the  exercise  of a
          Stock  Appreciation  Right  shall  not  again be  available  for grant
          pursuant to the Plan.  Stock  delivered  upon the  exercise of a Stock
          Appreciation  Right shall not be charged  against the number of shares
          of Stock available for the grant of options.

     (c)  Upon the  exercise  of an option  or a Stock  Appreciation  Right,  or
          payment of a Restricted  Stock award, the Company may distribute newly
          issued  shares  or  shares  previously  repurchased  on  behalf of the
          Company through a broker or other  independent agent designated by the
          Committee.  Such  repurchases  shall  be  subject  to such  rules  and
          procedures  as the  Committee  may  establish  hereunder  and shall be
          consistent with such conditions as may be prescribed from time to time
          by law or by the  Securities  and Exchange  Commission  ("SEC") in any
          rule or  regulation  or in any  exemptive  order or  no-action  letter
          issued by the SEC to the  Company  or the broker  with  respect to the
          making of such purchase or otherwise.

ARTICLE II - OPTIONS, STOCK APPRECIATION RIGHTS AND RESTRICTED STOCK

2.1  Granting of Options

     The Committee may grant Incentive Stock Options (ISOs),  Nonstatutory Stock
     Options or any combination thereof, provided that the aggregate Fair Market
     Value (determined at the time the option is granted) of the shares of Stock
     with  respect  to  which  ISOs are  exercisable  for the  first  time by an
     employee  during any  calendar  year (under this Plan and any other  option
     plan of the Company or its Subsidiaries) shall not exceed $100,000. No such
     maximum limitation shall apply to Nonstatutory Stock Options.

2.2  Terms and Conditions of Options

     Each option granted under the Plan shall be authorized by the Committee and
     shall be evidenced by an instrument delivered 
<PAGE>

     to the  Participant,  in a form approved by the  Committee,  containing the
     following  terms and  conditions and such other terms and conditions as the
     Committee may deem appropriate.

     (a)  Option Term - Each option shall  specify the term for which the option
          thereunder  is granted and shall  provide that the option shall expire
          at the end of such term.  In no event shall any option be  exercisable
          any earlier than one year after the date of such grant.  The Committee
          shall have  authority to grant  options  exercisable  in cumulative or
          non-cumulative installments.  No option shall be exercisable after the
          expiration  of ten  years  from the date  upon  which  such  option is
          granted. Notwithstanding anything to the contrary contained herein, in
          the  event of a Change  in  Control,  all  outstanding  options  shall
          immediately become exercisable.

     (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 proper  written  notice to the
               Company or its duly  authorized  agent  accompanied by the proper
               amount of payment  for the  shares,  as  provided  under  Section
               2.2(d) hereunder.

          (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
<PAGE>

               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 or if  permitted by the  Committee,  by tendering
               shares of Stock of the  Company  (by either  actual  delivery  of
               shares or by attestation,  with such shares valued at Fair Market
               Value as of the day of  exercise)  held by the  purchaser  for at
               least six months; or in any combination thereof, as determined by
               the Committee; or

          (2)  if  permitted  by the  Committee,  a  Participant  may  elect  to
               authorize a third party to sell shares of Stock (or a  sufficient
               portion of the shares)  acquired  upon exercise of the option and
               remit to the Company a sufficient  portion of the sales
<PAGE>

               proceeds to pay the entire exercise price and any tax withholding
               resulting from such exercise.

     (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 
<PAGE>

          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
<PAGE>

          (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  
<PAGE>

               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
<PAGE>

          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)
<PAGE>
          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.

     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;
<PAGE>

     (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 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.
