Exhibit A                  Term Loan Note

Schedule I                 Opinion of Robert C. Walker, Esq.

                                      iii


                  TERM LOAN AGREEMENT (this "Agreement"),  dated as of September
6, 2000, between AMERICAN INTERNATIONAL GROUP, INC., a Delaware corporation (the
"Lender"), and HSB GROUP, INC., a Connecticut corporation (the "Company").

                  WHEREAS, an Agreement and Plan of Merger among the Lender, the
Company and Engine Acquisition  Corporation,  dated August 17, 2000 (the "Merger
Agreement"),  contemplates  the  retirement of certain  Capital  Securities  (as
defined in Section 8.01); and

                  WHEREAS,  the  Lender  is  prepared  to  extend  the  Loan (as
hereinafter defined) to finance such retirement of the Capital Securities;

                  NOW,  THEREFORE,  the Lender and the Company  hereby  agree as
follows:


                                    ARTICLE I

                                    Term Loan

     Section 1.01.  Term Loan and Note.  Subject to the terms and  conditions of
this Agreement,  the Lender agrees to make a loan (the "Loan") to the Company on
September 14, 2000,  or such earlier other date as the parties  hereto may agree
(the "Closing Date"), in the principal amount of $315 million. The obligation of
the Company to repay the Loan, with interest thereon as hereinafter  prescribed,
shall be  evidenced by a promissory  note of the Company,  substantially  in the
form of Exhibit A (the  "Note"),  payable to the order of the  Lender.  The Note
shall be dated the Closing  Date,  shall mature on  September  30, 2005 (as such
date may be accelerated,  the "Maturity  Date") and shall bear interest from the
Closing  Date on the  principal  balance  thereof at the rate and payable on the
dates provided herein.


                                   ARTICLE II

                                    Interest

Section 2.01.  Interest on the Loan.  The Loan shall bear interest on the unpaid
principal amount thereof at a rate per annum (on the basis of a 360-day year for
the actual number of days involved)  equal to a percent per annum,  agreed to by
the parties on the Closing Date, such rate to be  approximately  50 basis points
in excess of the Lender's funding cost for debt of similar maturity to the Loan.



     Section  2.02.  Payment of Interest.  Interest on the Loan shall be payable
quarterly on the last Business Day of each March, June,  September and December,
commencing on the first such date after the Closing Date, and on the date of any
repayment of principal as provided in Section 3.01.

     Section 2.03.  Post Maturity  Interest.  After the principal  amount of the
Loan shall become due and payable  (whether by acceleration  or otherwise),  the
Loan shall bear interest,  payable on demand,  at a rate per annum (on the basis
of a 360-day year for the actual number of days involved)  equal to 2 percent in
excess of the rate per annum specified in Section 2.01.

     Section  2.04.  Use of  Proceeds.  The proceeds of the Loan will be used to
retire the Capital Securities.


                                   ARTICLE III

                            Payments and Prepayments

     Section 3.01.  Optional  Prepayments.  The Company shall have the right, at
any time and from time to time, to prepay the Loan, in whole or in part, without
premium or penalty,  upon at least three  Business  Days'  notice to the Lender,
specifying  the date of  prepayment  and the amount of  prepayment.  Such notice
shall be irrevocable  and the payment  amount  specified in such notice shall be
due and payable on the date  specified,  together with accrued  interest to such
date on the amount prepaid.  Partial prepayments shall be in a minimum aggregate
principal  amount of  $50,000,000  or,  if  greater,  an  integral  multiple  of
$25,000,000.

     Section 3.02. Mandatory  Prepayments.  The Company shall prepay the Loan in
whole, and the Note shall become due and payable in full,  together with accrued
interest to such date on the amount prepaid,  on the earlier of (x) the Business
Day on which the Company  terminates  the Merger  Agreement  pursuant to Section
7.1(b)(iv)  thereof and (y) the first Business Day after the thirtieth day after
the Closing Date if the Capital  Securities have not been retired on or prior to
such thirtieth day.

     Section 3.03. Method of Payment. Each payment and prepayment by the Company
of  principal  and  interest on the Note shall be made to the Lender,  in lawful
money of the  United  States and in  immediately  available  funds,  to a Lender
account located in the United States designated by the Lender.




                                   ARTICLE IV

                         Representations and Warranties

     Section 4.01.  Representations  and Warranties.  The Company represents and
warrants to the Lender that:

               (a) Good Standing.  The Company is a corporation  duly organized,
          validly  existing and in good standing  under the laws of the State of
          Connecticut  and has all  requisite  corporate  power and authority to
          own,  lease and operate its properties and to carry on its business as
          now being  conducted.  The Company is duly qualified or licensed to do
          business  and is in good  standing in each  jurisdiction  in which the
          nature of its business or the  ownership or leasing of its  properties
          make such  qualification  or  licensing  necessary,  except  where the
          failure to be so  qualified  or licensed or to be in good  standing is
          not,  individually  or in the aggregate,  reasonably  likely to have a
          Material Adverse Effect on the Company. As used in this Agreement, the
          phrase  "Material  Adverse  Effect on the  Company"  means a  material
          adverse effect on the condition (financial or otherwise),  properties,
          business,  or  results  of the  operations  of  the  Company  and  its
          subsidiaries  (as  defined  below)  taken as a whole,  other  than (i)
          effects  caused by changes in general  economic or securities  markets
          conditions,   (ii)  changes  or   conditions   that  affect  the  U.S.
          property-casualty  insurance  industry  in general,  (iii)  changes in
          generally  accepted  accounting   principles,   consistently   applied
          ("GAAP") or statutory  accounting practices prescribed or permitted by
          the  applicable   insurance  regulatory  authority  and  (iv)  effects
          resulting from the announcement of this Agreement and the transactions
          contemplated hereby.

               As used in this Agreement, the term "subsidiary" of a party shall
          mean  any  corporation  or other  entity  (including  joint  ventures,
          partnerships  and other  business  associations)  in which  such party
          directly or indirectly owns outstanding  capital stock or other voting
          securities  having the power to elect a majority of the  directors  or
          similar  members of the governing  body of such  corporation  or other
          entity,  or  otherwise  direct the  management  and  policies  of such
          corporation or other entity ("Voting Securities").


               (b) Each subsidiary of the Company (a "Company  Subsidiary") is a
          corporation  duly  organized,  validly  existing and in good  standing
          under  the  laws of its  jurisdiction  of  incorporation,  and has the
          corporate  or other  power and  authority  necessary  for it to own or
          lease its  properties and assets and to carry on its business as it is
          now being  conducted,  except  where the  failure to be so  organized,
          existing or in good  standing or to have such power and  authority  is
          not,  individually  or in the aggregate,  reasonably  likely to have a
          Material  Adverse  Effect on the Company.  Each Company  Subsidiary is
          duly  qualified or licensed to do business and is in good  standing in
          each jurisdiction in which the nature of its business or the ownership
          or leasing of its  properties  makes such  qualification  or licensing
          necessary,  except where the failure to be so qualified or licensed or
          to be in good  standing  is  not,  individually  or in the  aggregate,
          reasonably likely to have a Material Adverse Effect on the Company.

               (c) Power and Authority. The Company has full power and authority
          to enter  into  this  Agreement,  to issue  the Note and to incur  and
          perform the obligations  provided for herein and therein, all of which
          have been duly  authorized  by all proper  and  necessary  action.  No
          consent or approval of any governmental or  administrative  authority,
          instrumentality  or agency that has not been obtained is required as a
          condition to the validity of this Agreement or the Note.

               (d) Binding Agreement.  This Agreement constitutes,  and the Note
          when issued and  delivered  pursuant  hereto for value  received  will
          constitute,  the valid and legally binding  obligations of the Company
          enforceable  in accordance  with their terms,  subject to  bankruptcy,
          insolvency,  fraudulent  transfer,   reorganization,   moratorium  and
          similar  laws  of  general  applicability  relating  to  or  affecting
          creditors' rights and to general equity principles.

               (e)  Litigation.  There  are  no  proceedings  or  investigations
          pending or, to the  knowledge  of any  Executive  Officer,  threatened
          against  the  Company  or any  Company  Subsidiary  before  any court,
          arbitrator    or    governmental    or    administrative    authority,
          instrumentality  or agency that, in any one case or in the  aggregate,
          could  reasonably be expected to have a Material Adverse Effect on the
          Company  or a  material  adverse  effect on the  Company's  ability to
          perform its  obligations  under or pursuant to this  Agreement  or the
          Note.

               (f) No Conflicts. There is no statute, regulation, rule, order or
          judgment,  and no provision of any  mortgage,  indenture,  contract or
          agreement binding on the Company or affecting its property, that would
          conflict  with or prevent the  execution,  delivery or carrying out of
          the terms of this Agreement or the Note, and no consents or waivers of
          other lenders to the Company are required for the execution,  delivery
          or carrying out of the terms of this Agreement or the Note.

               (g) Financial Statements. The financial statements of the Company
          included or  incorporated  by reference in the  Company's  most recent
          report on Form 10-K and any  subsequent  reports on Form 10-Q filed by
          the Company  with the  Securities  and Exchange  Commission  have been
          prepared in accordance with generally accepted  accounting  principles
          and fairly  present the financial  condition and results of operations
          of the Company and its consolidated  subsidiaries as of the respective
          dates thereof  (subject,  in the case of such reports on Form 10-Q, to
          changes  resulting from normal year-end  adjustments).  There has been
          (x) no Material  Adverse  Effect on the Company  since the date of the
          Merger  Agreement and (y) no material adverse change since the date of
          the most recent such financial  statements in the financial  condition
          of the Company and its consolidated subsidiaries which would be likely
          to impair  materially the Company's ability to perform its obligations
          hereunder or under the Note.

               (h)  Pari  Passu  Obligations.  The  obligations  of the  Company
          hereunder  rank and will at all times  rank pari  passu with all other
          obligations   of  the  Company  in  respect  of  its   unsecured   and
          unsubordinated indebtedness for borrowed money.

               (i)  Regulatory  Compliance.  The  execution  and delivery by the
          Company of this  Agreement and the Note do not  constitute a violation
          of Regulation U or X of the Board of Governors of the Federal  Reserve
          System, as now in effect.


                                    ARTICLE V

                             Conditions of the Loan

     Section 5.01.  Conditions of the Loan. The obligation of the Lender to make
the Loan on the Closing Date is subject to the following conditions precedent:

               (a)  Compliance -- Terms and  Covenants.  The Company shall be in
          compliance  with  all the  terms,  covenants  and  conditions  of this
          Agreement  which are binding upon it and shall not have  intentionally
          violated any term, covenant and condition of the Merger Agreement.

               (b)  Compliance  -- No Events of  Default.  There  shall exist no
          Event of Default  and no event  which with the giving of notice or the
          lapse of time, or both, would constitute an Event of Default.

               (c)   Compliance   --   Representations   and   Warranties.   The
          representations and warranties contained in Article IV hereof shall be
          true  with  the  same  effect  as  though  such   representations  and
          warranties  had been  made at the time of the  Loan,  and the  Company
          shall not have taken any action since the date of the Merger Agreement
          that could  reasonably have been expected to cause any  representation
          or warranty in the Merger Agreement to be untrue as of the time of the
          Loan.

               (d) Opinions of Company Counsel. The Lender shall have received a
          favorable written opinion of Robert C. Walker,  General Counsel of the
          Company, in the form of Schedule I hereto.

               (e) The  Note.  The  Lender  shall  have  received  the Note duly
          executed by the Company.

               (f) Merger  Agreement  Termination.  No termination of the Merger
          Agreement pursuant to Section 7.1(b)(iv) thereof shall have occurred.

               (g) Compliance --  Certificate.  The Lender shall have received a
          certificate  dated  the  date of the  initial  Loan and  signed  by an
          Executive  Officer of the  Company as to the matters set forth in this
          Section 5.01.


                                   ARTICLE VI

                                    Covenants

     Section 6.01. Covenants.  Until payment in full of the Note and performance
of all other obligations of the Company hereunder:

          (a)  Financial  Statements  and Other  Reports  and  Information.  The
     Company will furnish to the Lender:

               (i) within 60 days after the end of each quarterly  fiscal period
          in each fiscal year of the Company (other than the last quarter in any
          fiscal year), a consolidated  statement of financial  condition of the
          Company and its subsidiaries as at the end of such period, prepared in
          accordance with GAAP and certified,  subject to changes resulting from
          subsequent  audit  adjustments,  by an  officer  of the  Company  with
          responsibility for financial matters;

               (ii)  within  90 days  after the end of each  fiscal  year of the
          Company,  a  consolidated  statement  of  financial  condition  of the
          Company  and  its  subsidiaries  as at the  end of  such  year,  and a
          consolidated  condensed  statement  of  revenues  and  expenses of the
          Company and its subsidiaries for such year, such financial  statements
          to be  audited  by  and  accompanied  by  an  opinion  of  independent
          certified  public   accountants  of   nationally-recognized   standing
          selected by the Company, which opinion shall state that such financial
          statements  have been  prepared in accordance  with GAAP  consistently
          applied  (except as  otherwise  stated in such  opinion)  and that the
          audit by such accountants in connection with such financial statements
          has  been  made  in  accordance  with  generally   accepted   auditing
          standards;

               (iii)  forthwith  upon  any  Executive  Officer  of  the  Company
          obtaining any knowledge of any condition or event which constitutes or
          which,  after  notice or lapse of time or both,  would  constitute  an
          Event of  Default,  a  certificate  executed by an  Executive  Officer
          specifying the nature and period of existence  thereof and what action
          the Company  has taken or is taking or  proposes to take with  respect
          thereto;

               (iv) together with each delivery of financial statements pursuant
          to  subdivisions  (i) and (ii)  above,  a  certificate  executed by an
          Executive  Officer  stating  that the signer has reviewed the terms of
          this  Agreement  and the Note and has made, or caused to be made under
          his or her supervision,  a review of the transactions and condition of
          the  Company  and the  Company's  Subsidiaries  during the  accounting
          period covered by such  financial  statements and that such review has
          not disclosed the existence  during such accounting  period,  and that
          the signer does not have  knowledge of the existence as of the date of
          such certificate, of any condition or event which constitutes an Event
          of  Default  or which,  after  notice or lapse of time or both,  would
          constitute  an Event of  Default  or, if any such  condition  or event
          existed or exists,  specifying  the nature and period of the existence
          thereof and what action the Company has taken or is taking or proposes
          to take with respect thereto;

               (v) together with each delivery of financial  statements pursuant
          to subdivision  (ii), a letter,  by the independent  certified  public
          accountants reporting thereon, (1) stating that they have examined and
          reported  upon  the  financial   statements   delivered   pursuant  to
          subdivision  (ii),  (2) stating  that for the  purposes of such letter
          they have read this  Agreement  insofar as it  relates  to  accounting
          matters and (3) stating  that during the course of their  audit,  they
          have not  obtained  any  knowledge  of any  condition  or event  which
          constitutes  an Event of  Default or which,  after  notice or lapse of
          time or both,  would constitute an Event of Default or, if their audit
          has disclosed such  condition or event,  specifying the nature and the
          period of existence thereof (but such accountants shall not be liable,
          directly or indirectly,  to anyone for failure to obtain  knowledge of
          any such condition or event); and


               (vi)  forthwith  upon  any  Executive   Officer  of  the  Company
          obtaining any knowledge of an event that could  reasonably be expected
          to result in the Company  terminating the Merger Agreement pursuant to
          Section  7.1(b)(iv)  thereof,  a certificate  executed by an Executive
          Officer  specifying  that  such an event  has  occurred,  providing  a
          description  of such event and what action the Company has taken or is
          taking or proposes to take with respect thereto; and

               (vii)  such   additional   financial   information,   reports  or
          statements  as the  Lender  may from time to time  reasonably  request
          consistent  with  the  Company's  policies  with  respect  to  similar
          borrowings.

     (b) Taxes.  The Company will pay and discharge all taxes,  assessments  and
governmental  charges and levies upon it, its income and its properties prior to
the  date  on  which  penalties  are  attached   thereto,   unless  such  taxes,
assessments,  governmental charges or levies shall be contested in good faith by
appropriate  proceedings and the Company shall have set aside adequate  reserves
with respect thereto (segregated to the extent required by GAAP).

     (c) Continued  Existence.  The Company will preserve and keep in full force
and effect its corporate existence in its jurisdiction of incorporation and will
not  directly  or  indirectly  sell,  lease  or  otherwise  dispose  of  all  or
substantially  all of its properties or assets or consolidate with or merge into
any other Person,  or permit any other Person to  consolidate  or merge with it;

merge into, a Successor Entity (as such term is defined in Section 8.06) and (y)
the Company may permit any other Person to merge or consolidate with the Company
if the Company is the survivor and if  immediately  after giving  effect to such
transaction there is no Event of Default and no event which upon notice or lapse
of time, or both, would constitute an Event of Default.

     (d)  Inspection.  The Company will permit the Lender to have one or more of
its officers or  employees,  or any other  persons  designated by the Lender and

the Company, any of the properties of the Company or any Company Subsidiary, and
to discuss the  Company's  or any Company  Subsidiary's  affairs,  finances  and
accounts with appropriate officers of the Company;  provided,  however, that the
Lender  shall use its  reasonable  efforts to minimize the impact of such visits
and inspections on the operations of the Company or any Company Subsidiary.

     (e)  Funding of Employee  Benefit  Plans.  The  Company  will comply in all
material  respects  with the funding  requirements  of the  Employee  Retirement
Income  Security  Act of 1974 with  respect to  employee  benefit  plans for its
employees.

     (f) Regulatory  Compliance.  The Company and the Company  Subsidiaries will
comply with all statutes,  regulations, orders and other regulatory requirements
the  noncompliance  with which would materially and adversely affect its ability
to conduct its  business as  presently  or  hereafter  conducted  or result in a
Material Adverse Effect on the Company.

     (g)  Ownership  and Control of HSBIIC and  HSBIICC.  The Company will cause
HSBIIC and  HSBIICC to remain  Company  Subsidiaries  and will  continue  to own
directly,  or indirectly through one or more wholly-owned  subsidiaries,  all of
the Voting Securities of HSBIIC and HSBIICC, free and clear of all liens, claims
and  encumbrances  other  than  (x)  liens  for  taxes,   assessments  or  other
governmental  charges  or levies  which are not yet due or are  payable  without
penalty or of which the amount,  applicability or validity is being contested by
the Company in good faith by appropriate  proceedings and the Company shall have
set aside on its books adequate reserves with respect thereto (segregated to the
extent required by GAAP), or (y) the liens of any judgment,  if such judgment is
being contested by the Company in good faith by appropriate  proceedings and the
Company shall have set aside on its books adequate reserves with respect thereto
(segregated to the extent required by GAAP).

         corporation in good standing under the laws of the State of Connecticut
         and has all  requisite  power  and  authority  to own and  operate  its
         properties and to carry on its business as now being conducted.

         into the  Agreement,  to make the borrowings  provided for therein,  to
         execute and deliver the Note and to perform its  obligations  under the
         Agreement and under the Note; and all necessary proceedings on its part
         to duly authorize such action have been taken.





                  3.  The  Agreement  has  been  duly  and  validly  authorized,
         executed  and  delivered  by the  Company and  constitutes  a valid and
         legally binding agreement of the Company enforceable in accordance with
         its terms,  subject to  bankruptcy,  insolvency,  fraudulent  transfer,
         reorganization,  moratorium  and similar laws of general  applicability
         relating  to or  affecting  creditors'  rights  and to  general  equity
         principles.

                  4. The Note has been duly and validly authorized, executed and
         delivered by the Company and  constitutes  a valid and legally  binding
         obligation of the Company,  enforceable  in  accordance  with the terms
         thereof  and of  the  Agreement,  subject  to  bankruptcy,  insolvency,
         fraudulent  transfer,  reorganization,  moratorium  and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

                  5. The  execution and delivery by the Company of the Agreement
         and the Note do not violate any  provision  of the Amended and Restated
         Certificate of Incorporation or By-laws of the Company.

                  6.  No   consent   or   approval   of  any   governmental   or
         administrative  authority,  instrumentality  or agency is required as a
         condition to the validity of the Agreement or the Note; and there is no
         statute,  rule or regulation which prevents the execution,  delivery or
         carrying out by the Company of the Agreement or the Note.

                  7. To the best of my knowledge and after due inquiry, there is
         no litigation or governmental  proceeding or  investigation  pending or
         threatened  against the Company or any  subsidiary  before any court or
         administrative  agency which could  reasonably be expected to result in
         any material  adverse change in the financial  condition of the Company
         and its subsidiaries taken as a whole.

                  The  foregoing  opinion is limited to the Federal  laws of the
United  States,  the laws of the  States of New York and  Connecticut,  and I am
expressing no opinion as to the effect of the laws of any other jurisdiction.

                  In  rendering  the  foregoing   opinion,  I  have,  with  your
approval,  relied as to certain  matters on  information  obtained  from  public
officials  and  officers of the Company and other  sources  believed by me to be
responsible, and I have assumed that the signatures on all documents examined by
me are genuine.

                                                     Very truly yours,
