        HSB Capital I, a trust formed under the laws of the State of
     Delaware (the "Issuer Trust"), hereby offers, upon the terms and
     subject to the conditions set forth in this Prospectus (as the
     same may be amended or supplemented from time to time, the
     "Prospectus") and in the accompanying Letter of Transmittal
     (which together constitute the "Exchange Offer"), to exchange up
     to $110,000,000 aggregate Liquidation Amount of its Global
     Floating Rate Capital Securities, Series B (the "Exchange Capital
     Securities") which have been registered under the Securities Act
     of 1933, as amended (the "Securities Act"), pursuant to a
     Registration Statement (as defined herein) of which this
     Prospectus constitutes a part, for a like Liquidation Amount of
     its outstanding Global Floating Rate Capital Securities, Series A
     (the "Original Capital Securities"), of which $110,000,000
     aggregate Liquidation Amount are issued and outstanding. 
     Pursuant to the Exchange Offer, HSB Group, Inc., a Connecticut
     corporation (the "Company" or "HSB"), is also offering to
     exchange (i) its guarantee of payments of cash distributions and
     payments on liquidation of the Issuer Trust or redemption of the
     Original Capital Securities (the "Original Guarantee") for a like
     guarantee in respect of the Exchange Capital Securities (the
     "Exchange Guarantee") and (ii) $110,000,000 aggregate principal
     amount of its Global Floating Rate Junior Subordinated Deferrable
     Interest Debentures, Series A due July 15, 2027 (the "Original
     Junior Subordinated Debentures") for a like aggregate principal
     amount of its Global Floating Rate Junior Subordinated Deferrable
     Interest Debentures, Series B due July 15, 2027 (the "Exchange
     Junior Subordinated Debentures"), which Exchange Guarantee and
     Exchange Junior Subordinated Debentures also have been registered
     under the Securities Act.  The Original Capital Securities, the
     Original Guarantee and the Original Junior Subordinated
     Debentures are collectively referred to herein as the "Original
     Securities" and the Exchange Capital Securities, the Exchange
     Guarantee and the Exchange Junior Subordinated Debentures are
     collectively referred to herein as the "Exchange Securities."

        The terms of the Exchange Securities are identical in all
     material respects to the respective terms of the Original
     Securities, except that (i) the Exchange Securities have been
     registered under the Securities Act and therefore will not be
     subject to certain restrictions on transfer applicable to the
     Original Securities, (ii) the Exchange Capital Securities
     initially sold to institutional accredited investors will not
     contain the $100,000 minimum Liquidation Amount transfer
     restriction, (iii) the Exchange Capital Securities will not
     provide for any increase in the Distribution rate thereon, and
     (iv) the Exchange Junior Subordinated Debentures will not provide
     for any increase in the interest rate thereon.  See "Description
     of Exchange Securities" and "Description of Original Securities." 
     The Exchange Capital Securities are being offered for exchange in
     order to satisfy certain obligations of the Company and the
     Issuer Trust under the Registration Rights Agreement dated as of
     July 10, 1997 (the "Registration Rights Agreement") among the
     Company, the Issuer Trust and the Initial Purchasers (as defined
     herein).  In the event that the Exchange Offer is consummated,
     any Original Capital Securities which remain outstanding after
     consummation of the Exchange Offer and the Exchange Capital
     Securities issued in the Exchange Offer will vote together as a
     single class for purposes of determining whether holders of the
     requisite percentage in outstanding Liquidation Amount thereof
     have taken certain actions or exercised certain rights under the
     Trust Agreement.
                                                  (continued on the
                                                  following page)

        This Prospectus and the Letter of Transmittal are first being
     mailed to all holders of Original Capital Securities on         ,
     1997.

        SEE "RISK FACTORS" COMMENCING ON PAGE 17 FOR CERTAIN
     INFORMATION THAT SHOULD BE CONSIDERED BY HOLDERS IN DECIDING
     WHETHER TO TENDER ORIGINAL CAPITAL SECURITIES IN THE EXCHANGE
     OFFER.

       THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
       SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
             COMMISSION NOR HAS THE SECURITIES AND EXCHANGE
              COMMISSION OR ANY STATE SECURITIES COMMISSION
                 PASSED UPON THE ACCURACY OR ADEQUACY OF
                THIS PROSPECTUS.  ANY REPRESENTATION TO THE 
                      CONTRARY IS A CRIMINAL OFFENSE.

             The date of this Prospectus is October    , 1997.


          The Exchange Capital Securities and the Original Capital
     Securities (collectively, the "Capital Securities") represent
     beneficial interests in the assets of the Issuer Trust.  The
     Company is the owner of all of the beneficial interests
     represented by common securities of the Issuer Trust (the "Common
     Securities," and together with the Capital Securities, the "Trust
     Securities").  The First National Bank of Chicago is the Property
     Trustee (the "Property Trustee") of the Issuer Trust.  The Issuer
     Trust exists for the sole purpose of issuing the Trust Securities
     and investing the proceeds thereof in the Junior Subordinated
     Debentures (as defined herein).  The Junior Subordinated
     Debentures will mature on July 15, 2027 (the "Stated Maturity"). 
     The Capital Securities will have a preference over the Common
     Securities under certain circumstances with respect to cash
     distributions and amounts payable on liquidation, redemption or
     otherwise.  See "Description of Exchange Securities--Description
     of Exchange Capital Securities--Subordination of Common
     Securities."

          As used herein, (i) the "Indenture" means the Junior
     Subordinated Indenture, dated as of July 15, 1997, as amended and
     supplemented from time to time, between the Company and The First
     National Bank of Chicago, as trustee (the "Debenture Trustee"),
     relating to the Junior Subordinated Debentures, (ii) the "Trust
     Agreement" means the Amended and Restated Trust Agreement
     relating to the Trust among the Company, as Sponsor, The First
     National Bank of Chicago, as Property Trustee, First Chicago
     Delaware Inc., an affiliate of the Property Trustee, as Delaware
     Trustee (the "Delaware Trustee"), and the Administrative Trustees
     named therein (collectively, with the Property Trustee and
     Delaware Trustee, the "Issuer Trustees"), (iii) the "Guarantee"
     means the Guarantee Agreement relating to the Capital Securities
     between the Company and The First National Bank of Chicago, as
     trustee (the "Guarantee Trustee") and (iv) the "Common Guarantee"
     means the Guarantee Agreement relating to the Common Securities
     between the Company and The First National Bank of Chicago, as
     trustee.  In addition, as the context may require, (i) "Junior
     Subordinated Debentures" includes the Original Junior
     Subordinated Debentures and the Exchange Junior Subordinated
     Debentures and (ii) "Guarantee" includes the Original Guarantee
     and the Exchange Guarantee.

          Holders of the Capital Securities will be entitled to
     receive preferential cumulative cash distributions accumulating
     from the date of original issuance and payable quarterly in
     arrears on January 15, April 15, July 15, and October 15, of each
     year, commencing October 15, 1997, at a variable annual rate
     equal to LIBOR (as defined herein) plus .91% on the Liquidation
     Amount (as defined herein) of $1,000 per Capital Security
     ("Distributions").  The Company has the right to defer payment of
     interest on the Junior Subordinated Debentures at any time or
     from time to time for a period not exceeding 20 consecutive
     quarterly periods with respect to each deferral period (each, an
     "Extension Period"), provided that no Extension Period may extend
     beyond the Stated Maturity (as defined herein) of the Junior
     Subordinated Debentures.  Upon the termination of any such
     Extension Period and the payment of all amounts then due, the
     Company may elect to begin a new Extension Period subject to the
     requirements set forth herein.  If interest payments on the
     Junior Subordinated Debentures are so deferred, Distributions on
     the Capital Securities will also be deferred and the Company will
     not be permitted, subject to certain exceptions described herein,
     to declare or pay any cash distributions with respect to the
     Company's capital stock or debt securities of the Company that
     rank pari passu in all respects with or junior to the Junior
     Subordinated Debentures. During an Extension Period, interest on
     the Junior Subordinated Debentures will continue to accrue (and
     the amount of Distributions to which holders of the Capital
     Securities are entitled will accumulate) at a variable annual
     rate equal to LIBOR plus .91%, compounded quarterly from the
     relevant payment date for interest and holders of Capital
     Securities will be required to recognize interest income for
     United States federal income tax purposes.  See "Description of
     Exchange Securities--Description of Exchange Junior Subordinated
     Debentures--Option To Extend Interest Payment Period" and "Certain
     Federal Income Tax Consequences--Interest Income and original
     Issue Discount."

          The Company has, through the Guarantee, the Trust Agreement,
     the Junior Subordinated Debentures and the Junior Subordinated
     Indenture (each as defined herein), taken together, fully,
     irrevocably and unconditionally guaranteed all of the Issuer
     Trust's obligations under the Capital Securities.  See
     "Relationship Among the Exchange Capital Securities, the Exchange
     Junior Subordinated Debentures and the Exchange Guarantee--Full
     and Unconditional Guarantee."  The Guarantee of the Company
     guarantees the payment of Distributions and payments on
     liquidation or redemption of the Capital Securities, but only in
     each case to the extent of funds held by the Issuer Trust, as
     described herein (the "Guarantee").  See "Description of Exchange
     Securities--Description of Exchange Guarantee."  If the Company
     does not make interest payments on the Junior Subordinated
     Debentures held by the Issuer Trust, the Issuer Trust will have
     insufficient funds to pay Distributions on the Capital
     Securities.  The Guarantee does not cover payment of
     Distributions when the Issuer Trust does not have sufficient
     funds to pay such Distributions.  In such event, a holder of
     Capital Securities may institute a legal proceeding directly
     against the Company to enforce payment of such Distributions to
     such holder.  See "Description of Exchange Securities--Description
     of Junior Exchange Subordinated Debentures--Enforcement of Certain
     Rights by Holders of Capital Securities."  The obligations of the
     Company under the Guarantee and the Junior Subordinated
     Debentures are subordinate and junior in right of payment to all
     Senior Indebtedness (as defined in "Description of Exchange
     Securities--Description of Exchange Junior Subordinated
     Debentures--Subordination") of the Company.  In addition, because
     the Company is a holding company, the right  of the Company to
     participate in any distribution of assets of any subsidiary
     including its insurance subsidiaries, upon any such subsidiary's
     liquidation or reorganization or otherwise is subject to the
     prior claims of creditors of that subsidiary except to the extent
     that the Company may itself be recognized as a creditor of that
     subsidiary.  Accordingly, the Junior Subordinated Debentures (and
     therefore the Capital Securities) will be effectively
     subordinated to all existing and future liabilities of the
     Company's subsidiaries under generally accepted accounting
     principals ("GAAP"), and holders thereof should look only to the
     assets of the Company for payments on the Junior Subordinated
     Debentures.  See "Risk Factors--Holding Company Structure;
     Structural Subordination; Dividend Restrictions."

          The Capital Securities are subject to mandatory redemption,
     in whole or in part, upon repayment of the Junior Subordinated
     Debentures at Stated Maturity or their earlier redemption.  The
     Junior Subordinated Debentures are redeemable prior to maturity
     at the option of the Company (i) on or after July 15, 2007, in
     whole at any time or in part from time to time, or (ii) in whole
     (but not in part) prior to July 15, 2007 and within 90 days
     following the occurrence of a Tax Event at a redemption price set
     forth herein plus the accrued and unpaid interest on the Junior
     Subordinated Debentures so redeemed to the date fixed for
     redemption. See "Description of Exchange Securities--Description
     of Exchange Junior Subordinated Debentures--Redemption."

          The Company, as the holder of the outstanding Common
     Securities, has the right at any time to terminate the Issuer
     Trust and, after satisfaction of the liabilities of creditors of
     the Issuer Trust as provided by applicable law, cause the Junior
     Subordinated Debentures to be distributed to the holders of the
     Capital Securities and Common Securities in liquidation of the
     Issuer Trust, subject to the Property Trustee having received an
     opinion of counsel to the effect that such distribution will not
     be a taxable event to holders of Capital Securities. See
     "Description of Exchange Securities--Description of Exchange
     Capital Securities--Liquidation Distribution Upon Termination."

          In the event of the termination of the Issuer Trust, after
     satisfaction of liabilities to creditors of the Issuer Trust as
     required by applicable law, the holders of the Capital Securities
     will be entitled to receive a Liquidation Amount of $1,000 per
     Capital Security plus accumulated and unpaid Distributions
     thereon to the date of payment, which may be in the form of a
     distribution of such amount in Junior Subordinated Debentures,
     subject to certain exceptions.  See "Description of Exchange
     Securities--Exchange Capital Securities--Liquidation Distribution
     Upon Termination".

          The Issuer Trust is making the Exchange Offer of the
     Exchange Capital Securities in reliance on the position of the
     staff of the Division of Corporation Finance of the Securities
     and Exchange Commission (the "Commission") as set forth in
     certain interpretive letters addressed to third parties in other
     transactions.  However, neither the Company nor the Issuer Trust
     has sought its own interpretive letter and there can be no
     assurance that the staff of the Division of Corporation Finance
     of the Commission would make a similar determination with respect
     to the Exchange Offer as it has in such interpretive letters to
     third parties.  Based on these interpretations by the staff of
     the Division of Corporation Finance of the Commission, and
     subject to the two immediately following sentences, the Company
     and the Issuer Trust believe that Exchange Capital Securities
     issued pursuant to this Exchange Offer in exchange for Original
     Capital Securities may be offered for resale, resold and
     otherwise transferred by a holder thereof (other than a holder
     who is a broker-dealer) without further compliance with the
     registration and prospectus delivery requirements of the
     Securities Act, provided that such Exchange Capital Securities
     are acquired in the ordinary course of such holder's business and
     that such holder is not participating, and has no arrangement or
     understanding with any person to participate, in a distribution
     (within the meaning of the Securities Act) of such Exchange
     Capital Securities.  However, any holder of Original Capital
     Securities who is an "affiliate" of the Company or the Issuer
     Trust or who intends to participate in the Exchange Offer for the
     purpose of distributing Exchange Capital Securities, or any
     broker-dealer who purchased Original Capital Securities from the
     Issuer Trust to resell pursuant to Rule 144A under the Securities
     Act ("Rule 144A") or any other available exemption under the
     Securities Act, (a) will not be able to rely on the
     interpretations of the staff of the Division of Corporation
     Finance of the Commission set forth in the above-mentioned
     interpretive letters, (b) will not be permitted or entitled to
     tender such Original Capital Securities in the Exchange Offer and
     (c) must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with any sale or
     other transfer of such Original Capital Securities unless such
     sale is made pursuant to an exemption from such requirements.  In
     addition, as described below, if any broker-dealer holds Original
     Capital Securities acquired for its own account as a result of
     market-making or other trading activities and exchanges such
     Original Capital Securities for Exchange Capital Securities, then
     such broker-dealer must deliver a prospectus meeting the
     requirements of the Securities Act in connection with any resales
     of such Exchange Capital Securities.

          Each holder of Original Capital Securities who wishes to
     exchange Original Capital Securities for Exchange Capital
     Securities in the Exchange Offer will be required to represent
     that (i) it is not an "affiliate" of the Company or the Issuer
     Trust, (ii) any Exchange Capital Securities to be received by it
     are being acquired in the ordinary course of its business, (iii)
     it has no arrangement or understanding with any person to
     participate in a distribution (within the meaning of the
     Securities Act) of such Exchange Capital Securities, and (iv) if
     such holder is not a broker-dealer, such holder is not engaged
     in, and does not intend to engage in, a distribution (within the
     meaning of the Securities Act) of such Exchange Capital
     Securities.  In addition, the Company and the Issuer Trust may
     require such holder, as a condition to such holder's eligibility
     to participate in the Exchange Offer, to furnish to the Company
     and the Issuer Trust (or an agent thereof) in writing information
     as to the number of "beneficial owners" (within the meaning of
     Rule 13d-3 under the Securities Exchange Act of 1934, as amended
     (the "Exchange Act")) on behalf of whom such holder holds the
     Capital Securities to be exchanged in the Exchange Offer.  Each
     broker-dealer that receives Exchange Capital Securities for its
     own account pursuant to the Exchange Offer must acknowledge that
     it acquired the Original Capital Securities for its own account
     as the result of market-making activities or other trading
     activities and must agree that it will deliver a prospectus
     meeting the requirements of the Securities Act in connection with
     any resale of such Exchange Capital Securities.  The Letter of
     Transmittal states that by so acknowledging and by delivering a
     prospectus, a broker-dealer will not be deemed to admit that it
     is an "underwriter" within the meaning of the Securities Act. 
     Based on the position taken by the staff of the Division of
     Corporation Finance of the Commission in the interpretive letters
     referred to above, the Company and the Issuer Trust believe that
     broker-dealers who acquired Original Capital Securities for their
     own accounts, as a result of market-making activities or other
     trading activities ("Participating Broker-Dealers"), may fulfill
     their prospectus delivery requirements with respect to the
     Exchange Capital Securities received upon exchange of such
     Original Capital Securities (other than Original Capital
     Securities which represent an unsold allotment from the initial
     sale of the Original Capital Securities) with a prospectus
     meeting the requirements of the Securities Act, which may be the
     prospectus prepared for an exchange offer so long as it contains
     a description of the plan of distribution with respect to the
     resale of such Exchange Capital Securities.  Each broker-dealer
     that receives Exchange Capital Securities for its own account
     pursuant to the Exchange Offer must acknowledge that it will
     deliver a prospectus in connection with any resale of such
     Exchange Capital Securities.  The Letter of Transmittal states
     that by so acknowledging and by delivery of a prospectus, a
     broker-dealer will not be deemed to admit that it is an
     "underwriter" within the meaning of the Securities Act.  This
     Prospectus, as it may be amended or supplemented from time to
     time, may be used by a broker-dealer in connection with resales
     of Exchange Capital Securities received in exchange for Original
     Capital Securities acquired by such broker-dealer as a result of
     market-making activities or other trading activities.  The Issuer
     Trust and the Company have agreed that, ending on the close of
     business on the 180th day following the Expiration Date (as
     defined herein), it will make this Prospectus available to any
     broker-dealer for use in connection with any such resale.  See
     "Plan of Distribution." However, a Participating Broker-Dealer
     who intends to use this Prospectus in connection with the resale
     of Exchange Capital Securities received in exchange for Original
     Capital Securities pursuant to the Exchange Offer must notify the
     Company or the Issuer Trust, or cause the Company or the Issuer
     Trust to be notified, on or prior to the Expiration Date, that is
     a Participating Broker-Dealer.  Such notice may be given in the
     space provided for that purpose in the Letter of Transmittal or
     may be delivered to the Exchange Agent at one of the addresses
     set forth herein under "The Exchange Offer-Exchange Agent."  Any
     Participating Broker-Dealer who is an "affiliate" of the Company
     or the Issuer Trust may not rely on such interpretive letters and
     must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with any resale
     transaction. See "The Exchange Offer--Resales of Exchange Capital
     Securities."

          In that regard, each Participating Broker-Dealer who
     surrenders Original Capital Securities pursuant to the Exchange
     Offer will be deemed to have agreed, by execution of the Letter
     of Transmittal, that upon receipt of notice from the Company or
     the Issuer Trust of the occurrence of any event or the discovery
     of any fact which makes any statement contained or incorporated
     by reference in this Prospectus untrue in any material respect or
     which causes this Prospectus to omit to state a material fact
     necessary in order to make the statements contained or
     incorporated by reference herein, in light of the circumstances
     under which they were made, not misleading or of the occurrence
     of certain other events specified in the Registration Rights
     Agreement, such Participating Broker-Dealer will suspend the sale
     of Exchange Capital Securities (or the Exchange Guarantee or the
     Exchange Junior Subordinated Debentures, as applicable) pursuant
     to this Prospectus until the Company or the Issuer Trust has
     amended or supplemented this Prospectus to correct such
     misstatement or omission and has furnished copies of the amended
     or supplemented Prospectus to such Participating Broker-Dealer,
     or the Company or the Issuer Trust has given notice that the sale
     of the Exchange Capital Securities (or the Exchange Guarantee or
     the Exchange Junior Subordinated Debentures, as applicable) may
     be resumed, as the case may be.  If the Company or the Issuer
     Trust gives such notice to suspend the sale of the Exchange
     Capital Securities (or the Exchange Guarantee or the Exchange
     Junior Subordinated Debentures, as applicable), it shall extend
     the 180-day period referred to above during which Participating
     Broker-Dealers are entitled to use this Prospectus in connection
     with the resale of Exchange Capital Securities by the number of
     days during the period from and including the date of the giving
     of such notice to and including the date when Participating
     Broker-Dealers shall have received copies of the amended or
     supplemented Prospectus necessary to permit resales of the
     Exchange Capital Securities or to and including the date on which
     the Company or the Issuer Trust has given notice that the sale of
     Exchange Capital Securities (or the Exchange Guarantee or the
     Exchange Junior Subordinated Debentures, as applicable) may be
     resumed, as the case may be.

          Prior to the Exchange Offer, there has been only a limited
     secondary market and no public market for the Original Capital
     Securities.  The Exchange Capital Securities will be a new issue
     of securities for which there currently is no market.  Although
     Goldman Sachs & Co. and Conning & Co., the initial purchasers of
     the Original Capital Securities (the "Initial Purchasers"), have
     informed the Company and the Issuer Trust that they each
     currently intend to make a market in the Exchange Capital
     Securities, they are not obligated to do so, and any such market
     making may be discontinued at any time without notice. 
     Accordingly, there can be no assurance as to the development or
     liquidity of any market for the Exchange Capital Securities.  The
     Company and the Issuer Trust currently do not intend to apply for
     listing of the Exchange Capital Securities on any securities
     exchange or for quotation through the NASD Automated Quotation
     System.

          Any Original Capital Securities not tendered and accepted in
     the Exchange Offer will remain outstanding and will be entitled
     to all the same rights and will be subject to the same
     limitations applicable thereto under the Declaration (except for
     those rights which terminate upon consummation of the Exchange
     Offer).  Following consummation of the Exchange Offer, the
     holders of Original Capital Securities will continue to be
     subject to all of the existing restrictions upon transfer thereof
     and neither the Company nor the Issuer Trust will have any
     further obligation to such holders (other than under certain
     limited circumstances) to provide for registration under the
     Securities Act of the Original Capital Securities held by them. 
     To the extent that Original Capital Securities are tendered and
     accepted in the Exchange Offer, a holder's ability to sell
     untendered Original Capital Securities could be adversely
     affected.  See "Risk Factors--Consequences of a Failure to
     Exchange Original Capital Securities."

          THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL
     CONTAIN IMPORTANT INFORMATION.  HOLDERS OF ORIGINAL CAPITAL
     SECURITIES ARE URGED TO READ THIS PROSPECTUS AND THE RELATED
     LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER
     THEIR ORIGINAL CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER.

          Original Capital Securities may be tendered for exchange on
     or prior to 5:00 p.m., New York City time, on ______, 1997 (such
     time on such date being hereinafter called the "Expiration
     Date"), unless the Exchange Offer is extended by the Company or
     the Issuer Trust (in which case the term "Expiration Date" shall
     mean the latest date and time to which the Exchange Offer is
     extended).  Tenders of Original Capital Securities may be
     withdrawn at any time on or prior to the Expiration Date.  The
     Exchange Offer is not conditioned upon any minimum Liquidation
     Amount of Original Capital Securities being tendered for
     exchange.  However, the Exchange Offer is subject to certain
     events and conditions which may be waived by the Company or the
     Issuer Trust and to the terms and provisions of the Registration
     Rights Agreement.  Original Capital Securities may be tendered in
     whole or in part having an aggregate Liquidation Amount of not
     less than $1,000 (one Capital Security).  The Company has agreed
     to pay all expenses of the Exchange Offer.  See "The Exchange
     Offer--Fees and Expenses." Holders of the Original Capital
     Securities whose Original Capital Securities are accepted for
     exchange will not receive Distributions on such Original Capital
     Securities and will be deemed to have waived the right to receive
     any Distributions on such Original Capital Securities accumulated
     from and after October 15, 1997.  Accordingly, holders of
     Exchange Capital Securities as of the record date for the payment
     of Distributions on January 15, 1998 will be entitled to receive
     Distributions accumulated from and after October 15, 1997.  See
     "The Exchange Offer--Distributions on Exchange Capital
     Securities."

          Neither the Company nor the Issuer Trust will receive any
     cash proceeds from the issuance of the Exchange Capital
     Securities offered hereby.  No dealer-manager is being used in
     connection with this Exchange Offer.  See "Use of Proceeds" and
     "Plan of Distribution."

                           AVAILABLE INFORMATION

          The Company is subject to the informational requirements of
     the Exchange Act and in accordance therewith, files reports,
     proxy statements and other information with the Commission.  Such
     reports, proxy statements and other information may be inspected

     securities of the Company are listed.

          No separate financial statements of the Issuer Trust have
     been included herein.  The Company and the Issuer Trust do not
     consider that such financial statements would be material to
     holders of the Capital Securities because the Issuer Trust is a
     newly formed special purpose entity, has no operating history or
     independent operations and is not engaged in and does not propose
     to engage in any activity other than holding as trust assets the
     Junior Subordinated Debentures, issuing the Trust Securities and
     engaging in incidental activities.  See "HSB Capital I,"
     "Description of Exchange Securities." In addition, the Company
     does not expect that the Trust will file reports, proxy
     statements and other information under the Exchange Act with the
     Commission.

     statement on Form S-4 (the "Registration Statement") filed by the
     Company and the Issuer Trust with the Commission under the
     Securities Act.  This Prospectus does not contain all the

                             PROSPECTUS SUMMARY

          The following summary is qualified in its entirety by the
     more detailed information appearing elsewhere in this Prospectus.

                              HSB GROUP, INC.

          HSB Group, Inc. ("the Company" and together with its
     subsidiaries "HSB Group") is a newly formed holding company which
     owns directly or indirectly, a number of insurance and
     engineering service subsidiaries which specialize in insuring
     against losses from accidents to boilers, pressure vessels and
     mechanical and electrical machinery and equipment, and in
     providing related engineering services.  HSB Group's operations
     are divided into three industry segments insurance, engineering
     services and investments.

          The most significant subsidiary of the Company is The
     Hartford Steam Boiler Inspection and Insurance Company ("Hartford
     Steam Boiler"), an insurance company chartered under the laws of
     the State of Connecticut in 1866.  Hartford Steam Boiler is the
     largest writer of equipment breakdown insurance in North America
     and is establishing a presence in the engineering insurance
     market outside of North America.  In 1996, earned premiums for
     HSB Group's insurance products were $448.6 million, approximately
     81.7 percent of the revenues of HSB Group.

          The Company's principal executive offices are located at One
     State Street, Hartford, Connecticut 06102.  The Company's
     telephone number is (860) 722-1866.

                               HSB CAPITAL I

          The Issuer Trust is a statutory business trust created under
     Delaware law pursuant to (i) the Trust Agreement executed by the
     Company, as Depositor, First Chicago, as Property Trustee and
     First Chicago Delaware Inc., as Delaware Trustee ("First Chicago
     (Delaware)"), and (ii) the filing of a certificate of trust with
     the Delaware Secretary of State.  The Issuer Trust's business and
     affairs are conducted by its trustees: First Chicago, as Property
     Trustee, and First Chicago (Delaware) as Delaware Trustee.  The
     Issuer Trust exists for the exclusive purposes of (i) issuing and
     selling the Trust Securities, (ii) using the proceeds from the
     sale of Trust Securities to acquire Junior Subordinated
     Debentures issued by the Company and (iii) engaging in only those
     other activities necessary or incidental thereto (such as
     registering the transfer of the Trust Securities).  Accordingly,
     the Junior Subordinated Debentures and the right to reimbursement
     of expenses under the related Expense Agreement will be the sole
     assets of the Issuer Trust, and payments under the Junior
     Subordinated Debentures and the related Expense Agreement will be
     the sole sources of revenue of the Issuer Trust.

                               the Issuer Trust are making the
                               Exchange Offer in order to satisfy
                               their obligations under the

                               Offer is extended by the Company or
                               the Issuer Trust (in which case the
                               Expiration Date will be the latest

     Resales of Exchange 
       Capital Securities .    The Company and the Issuer Trust are
                               making the Exchange Offer in reliance
                               on the position of the staff of the
                               Division of Corporation Finance of the
                               Commission as set forth in certain
                               interpretive letters addressed to
                               third parties in other transactions. 
                               However, neither the Company nor the
                               Issuer Trust has sought its own
                               interpretive letter and there can be
                               no assurance that the staff of the
                               Division of Corporation Finance of the
                               Commission would make a similar
                               determination with respect to the
                               Exchange Offer as it has in such
                               interpretive letters to third parties. 
                               Based on these interpretations by the
                               staff of the Division of Corporation
                               Finance of the Commission, and subject
                               to the two immediately following
                               sentences, the Company and the Issuer
                               Trust believe that Exchange Capital
                               Securities issued pursuant to this
                               Exchange Offer in exchange for
                               Original Capital Securities may be

                               otherwise transferred by a holder
                               thereof (other than a holder who is a
                               broker-dealer) without further
                               compliance with the registration and
                               prospectus delivery requirements of
                               the Securities Act, provided that such
                               Exchange Capital Securities are
                               acquired in the ordinary course of
                               such holder's business and that such
                               holder is not participating, and has
                               no arrangement or understanding with
                               any person to participate, in a
                               distribution (within the meaning of
                               the Securities Act) of such Exchange
                               Capital Securities.  However, any
                               holder of Original Capital Securities
                               who is an "affiliate" of the Company
                               or the Issuer Trust or who intends to
                               participate in the Exchange Offer for
                               the purpose of distributing the
                               Exchange Capital Securities, or any
                               broker-dealer who purchased the
                               Original Capital Securities from the
                               Issuer Trust to resell pursuant to
                               Rule 144A or any other available
                               exemption under the Securities Act,
                               (a) will not be able to rely on the
                               interpretations of the staff of the
                               Division of Corporation Finance of the
                               Commission set forth in the
                               above-mentioned interpretive letters,
                               (b) will not be permitted or entitled
                               to tender such Original Capital
                               Securities in the Exchange Offer and
                               (c) must comply with the registration
                               and prospectus delivery requirements
                               of the Securities Act in connection
                               with any sale or other transfer of
                               such Original Capital Securities

                               an exemption from such requirements. 
                               In addition, as described below, if
                               any broker-dealer holds Original
                               Capital Securities acquired for its

                               broker-dealer must deliver a
                               prospectus meeting the requirements of
                               the Securities Act in connection with

                               Each holder of Original Capital
                               Securities who wishes to exchange
                               Original Capital Securities for
                               Exchange Capital Securities in the
                               Exchange Offer will be required to
                               represent that (i) it is not an
                               "affiliate" of the Company or the
                               Issuer Trust, (ii) any Exchange
                               Capital Securities to be received by

                               no arrangement or understanding with
                               any person to participate in a
                               distribution (within the meaning of
                               the Securities Act) of such Exchange
                               Capital Securities, and (iv) if such
                               holder is not a broker-dealer, such
                               holder is not engaged in, and does not

                               Securities.  Each broker-dealer that
                               receives Exchange Capital Securities
                               for its own account in exchange for
                               Original Capital Securities, where
                               such Original Capital Securities were
                               acquired by such broker-dealer as a
                               result of market-making activities or
                               other trading activities, must

                               resale of such Exchange Capital
                               Securities.  See "Plan of
                               Distribution."  The Letter of
                               Transmittal states that, by so
                               acknowledging and by delivering a
                               prospectus, a broker-dealer will not
                               be deemed to admit that it is an
                               "underwriter" within the meaning of
                               the Securities Act.  Based on the
                               position taken by the staff of the
                               Division of Corporation Finance of the
                               Commission in the interpretive letters
                               referred to above, the Company and the
                               Issuer Trust believe that
                               Participating Broker-Dealers who
                               acquired Original Capital Securities
                               for their own accounts as a result of
                               market-making activities or other
                               trading activities may fulfill their
                               prospectus delivery requirements with
                               respect to the Exchange Capital
                               Securities received upon exchange of
                               such Original Capital Securities
                               (other than Original Capital
                               Securities which represent an unsold
                               allotment from the initial sale of the
                               Original Capital Securities) with a
                               prospectus meeting the requirements of
                               the Securities Act, which may be the
                               prospectus prepared for an exchange

                               distribution with respect to the
                               resale of such Exchange Capital
                               Securities.  Accordingly, this

     Absence of Market for 
       the Capital
       Securities  . . . .     The Exchange Capital Securities will
                               be a new issue of securities for which
                               there currently is no market. 
                               Although the Initial Purchasers have
                               informed the Issuer Trust and the
                               Company that they each currently
                               intend to make a market in the Capital
                               Securities, the Initial Purchasers are
                               not obligated to do so, and any such
                               market making may be discontinued at
                               any time without notice.  Accordingly,
                               there can be no assurance as to the
                               development or liquidity of any market
                               for the Capital Securities.  The
                               Issuer Trust and the Company do not
                               intend to apply for listing of the
                               Capital Securities on any securities
                               exchange or for quotation through the
                               NASD Automated Quotation System.  See
                               "Plan of Distribution."


          As used herein (i) the "Junior Subordinated Indenture" means
     the Junior Subordinated Indenture, as amended and supplemented
     from time to time, between the Company and First Chicago, as
     trustee (the "Debenture Trustee"), and (ii) the "Trust Agreement"
     means the Amended and Restated Trust Agreement relating to the
     Issuer Trust among the Company, as Depositor, the Property
     Trustee, and First Chicago (Delaware), as Delaware Trustee (the
     "Delaware Trustee") (collectively, the "Issuer Trustees").

                                RISK FACTORS

          Prospective investors in the Capital Securities should
     carefully review all of the information set forth in this
     Prospectus and, in particular, should consider the risk factors
     listed below.  Prospective investors are also cautioned that, in
     addition to the historical information included herein with
     respect to the Company, this Prospectus includes certain forward-
     looking statements and information that are based on the
     Company's beliefs as well as on assumptions made by and

     RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE
     JUNIOR SUBORDINATED DEBENTURES

          The obligations of the Company under the Guarantee issued by
     the Company for the benefit of the holders of Capital Securities
     and under the Junior Subordinated Debentures are subordinate and
     junior in right of payment to all Senior Indebtedness of the
     Company.  Because the Company is a holding company, the right of
     the Company to participate in any distribution of assets of any
     subsidiary upon such subsidiary's liquidation or reorganization
     or otherwise (and thus the ability of holders of the Capital
     Securities to benefit indirectly from such distribution) is
     subject to the prior claims of creditors of that subsidiary,
     except to the extent that the Company may itself be recognized as
     a creditor of that subsidiary.  In addition, there are various
     legal limitations on the extent to which the Company's
     subsidiaries may extend credit, pay dividends or otherwise supply
     funds to the Company or various of its affiliates.  Accordingly,
     the Junior Subordinated Debentures and Guarantee will be
     effectively subordinated to all existing and future liabilities
     of the Company's subsidiaries, and holders of Junior Subordinated
     Debentures and the Guarantee should look only to the assets of
     the Company for payments on the Junior Subordinated Debentures
     and the Guarantee.  See "HSB Group, Inc." None of the Junior
     Subordinated Indenture, the Guarantee or the Trust Agreement
     places any limitation on the amounts of secured or unsecured
     debt, including Senior Indebtedness, that may be incurred by the
     Company.  See "Description of Exchange Securities--Description of
     Exchange Guarantee--Status of the Guarantee" and "Description of
     Exchange Securities--Description of Exchange Junior Subordinated
     Debentures--Subordination."

          The ability of the Issuer Trust to pay amounts due on the
     Capital Securities is solely dependent upon the Company making
     payments on the Junior Subordinated Debentures as and when
     required.

     HOLDING COMPANY STRUCTURE; STRUCTURAL SUBORDINATION; DIVIDEND
     RESTRICTIONS

          Effective June 24, 1997, the Company was organized as a
     holding company with all of its operations being conducted by
     subsidiaries.  The Company, however, has, or in the future may
     have, continuing expenditures for administrative expenses,
     corporate services, the payment of principal and interest on
     borrowings, including the Junior Subordinated Debentures, and
     dividends on preferred stock.  In addition, Hartford Steam
     Boiler, the Company's most significant subsidiary, has
     historically paid dividends on its common shares, and it is
     anticipated that the Company will likewise pay dividends on its
     common stock at a rate which equals or exceeds the rate paid by
     Hartford Steam Boiler prior to the holding company formation.

          The Company expects to rely primarily on dividends and tax
     payments from its subsidiaries for funds to meet its obligations. 
     Payments of dividends by the insurance subsidiaries of the
     Company are subject to various laws and regulations which limit
     the amount of dividends that can be paid without prior approval
     from the applicable state department of insurance.  Under the
     insurance holding company laws of Connecticut which apply to
     Hartford Steam Boiler, approval of the insurance commissioner is
     required for payment of a dividend which when added to the other
     dividends or distributions made within the preceding twelve
     months, exceeds the greater of (i) 10% of policyholder surplus as
     of December 31 of the preceding year or (ii) net income for the
     twelve-month period ending on December 31 of the preceding year. 
     The maximum dividend permitted by law is not necessarily
     indicative of an insurer's actual ability to pay dividends, which
     may be further affected by business and regulatory
     considerations, such as the impact of dividends on surplus, which
     could affect an insurer's ratings, competitive position, the
     amount of premiums that can be written and the ability to pay
     future dividends.  Furthermore, each state department of
     insurance has broad discretion to limit the payment of dividends
     by insurance companies domiciled in that state.  A prolonged
     material decline in insurance subsidiary profits or materially
     adverse insurance regulatory developments, however, could subject
     the Company to shortages of cash because of its inability to
     receive dividends from subsidiaries.

          In addition, except to the extent that the Company may
     itself be a creditor with recognized claims against its
     subsidiaries, claims of creditors of such subsidiaries will have
     priority with respect to the assets and earnings of such
     subsidiaries over the claims of creditors of the Company,
     including claims under the Junior Subordinated Debentures and the
     Guarantee, even though such subsidiary obligations do not
     constitute Senior Indebtedness.  Accordingly, the Junior
     Subordinated Debentures will be effectively subordinated to all
     existing and future liabilities of the Company's subsidiaries,
     including loss reserves, unearned premium reserves and guarantee
     obligations.  GAAP basis liabilities of the subsidiaries,
     including loss reserves and unearned premium reserves aggregated
     $750.7 million at December 31, 1996.  In addition, Hartford Steam
     Boiler has agreed to guarantee up to $16 million in respect of
     debt incurred by Radian International, LLC, a joint venture
     between Hartford Steam Boiler and The Dow Chemical Company
     ("Radian International").  As of June 30, 1997, the guarantee was
     applicable to $13.7 million of Radian International.  Such
     guarantee will terminate upon the sale of the Company's interest
     in Radian International to The Dow Chemical Company which is
     expected to take place on or about January 1, 1997.  See "HSB
     Group, Inc.--Strategy; Recent History."

          In addition, in the event of a default on the Company's debt
     or an insolvency, liquidation or other reorganization of the
     Company, creditors of the Company will have no right to proceed
     against the assets of the subsidiaries or to cause their
     liquidation under federal and state bankruptcy laws.  If any of
     the Company's subsidiaries were to be liquidated, such
     liquidation would be conducted under the insurance laws of the
     domiciliary jurisdiction of such subsidiary by the insurance
     regulator as the receiver with respect to such subsidiary's
     property and business.

     REGULATION

          The Company's U.S. insurance subsidiaries are regulated
     under the insurance and insurance holding company laws of their
     state of domicile and other states in which they operate.  These
     laws, in general, require approval of the applicable insurance
     regulators prior to certain actions by the insurance companies,
     such as the payment of dividends in excess of statutory
     limitations (as discussed above under "Holding Company Structure;
     Structural Subordination; Dividend Restrictions") and certain
     transactions and continuing service arrangements with affiliates. 
     Regulation and supervision of each insurance subsidiary is
     administered by state insurance commissioners who have broad
     statutory powers with respect to the granting and revoking of
     licenses, approvals of premium rates, forms of insurance
     contracts and types and amounts of business which may be
     conducted in light of the policyholders' surplus of the
     particular company.  The statutes of most states provide for the
     filing of premium rates and such rates may be disapproved if they
     are found to be excessive, inadequate or unfairly discriminatory. 
     The determination of rates is based on various factors, including
     acquisition costs, engineering and loss and loss adjustment
     expense experience.  The failure to obtain, or delay in
     obtaining, the required approvals could have an adverse impact on
     the operations of the Company's insurance subsidiaries.

          The nature and extent of regulations pertaining to the
     business the Company writes outside of the U.S. varies
     considerably.  Regulations cover various financial and
     operational areas including such matters as amount and type of
     reserves, currency, policy language, repatriation of assets and
     compulsory cessions of reinsurance.

          Insurance regulatory authorities require property and
     casualty insurers to maintain a reasonable ratio between net
     premiums written and total capital and surplus.  Accordingly, a
     property and casualty insurance company's volume of net premiums
     written is limited by the amount of its capital and surplus.  In
     the absence of mitigating factors, a ratio of 3 to 1 or less is
     considered acceptable by most regulatory authorities.  Hartford
     Steam Boiler's historical ratio has been well within this range. 
     Nevertheless, adverse underwriting experience, significant losses
     in its investment portfolio or changes in statutory accounting
     principles could have a material negative impact on Hartford
     Steam Boiler's surplus to policyholders.

     OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES

          So long as no Event of Default under the Junior Subordinated
     Indenture (a "Debenture Event of Default") has occurred or is
     continuing, the Company has the right under the Junior
     Subordinated Indenture to defer the payment of interest on the
     Junior Subordinated Debentures at any time or from time to time
     for a period not exceeding 20 consecutive quarterly periods with
     respect to each Extension Period, provided that no Extension
     Period may extend beyond the Stated Maturity of the Junior
     Subordinated Debentures.  As a consequence of any such deferral,
     quarterly Distributions on the Capital Securities by the Issuer
     Trust will be deferred (and the amount of Distributions to which
     holders of the Capital Securities are entitled will accumulate
     additional Distributions thereon at the rate of the Floating Rate
     per annum, compounded quarterly from the relevant payment date
     for such Distributions) during any such Extension Period.  During
     any such Extension Period, the Company may not, and may not
     permit any subsidiary of the Company to, (i) declare or pay any
     dividends or distributions on, or redeem, purchase, acquire, or
     make a liquidation payment with respect to, any of the Company's
     capital stock, (ii) make any payment of principal, interest or
     premium, if any, on or repay, repurchase or redeem any debt
     securities of the Company (including other Junior Subordinated
     Debentures) that rank pari passu in all respects with or junior
     in interest to the Junior Subordinated Debentures or (iii) make
     any guarantee payments with respect to any guarantee by the
     Company of the debt securities of any subsidiary of the Company
     if such guarantee ranks pari passu with or junior in interest to
     the Junior Subordinated Debentures (other than (a) dividends or
     distributions in Company Common Stock, (b) any declaration of a
     dividend in connection with the implementation of a stockholders'
     rights plan, or the issuance of stock under any such plan in the
     future, or the redemption or repurchase of any such rights
     pursuant thereto, (c) payments under the Guarantee and (d)
     purchases of Company Common Stock related to the issuance of
     Company Common Stock or rights under any of the Company's or its
     subsidiaries' benefit plans for their directors, officers or
     employees).  Prior to the termination of any such Extension
     Period, the Company may further defer the payment of interest,
     provided that no Extension Period may exceed 20 consecutive
     quarterly periods or extend beyond the Stated Maturity of the
     Junior Subordinated Debentures.  Upon the termination of any
     Extension Period and the payment of all interest then accrued and
     unpaid (together with interest thereon at the annual rate of the
     Floating Rate, compounded quarterly, to the extent permitted by
     applicable law), the Company may elect to begin a new Extension
     Period subject to the above requirements.  There is no limitation
     on the number of times that the Company may elect to begin an
     Extension Period.  See "Description of Exchange Capital
     Securities--Distributions" and "Description of Exchange Junior
     Subordinated Debentures--Option To Extend Interest Payment
     Period."

          Should an Extension Period occur, a holder of Capital
     Securities will continue to accrue income (in the form of
     original issue discount) in respect of its pro rata share of the
     Junior Subordinated Debentures held by the Issuer Trust for
     United States federal income tax purposes, which will be
     allocated but not distributed, to holders of record of any
     Capital Securities.  As a result during such an Extension Period,
     a holder of Capital Securities will include such income in gross
     income for United States federal income tax purposes in advance
     of the receipt of cash, and will not receive the cash related to
     such income from the Issuer Trust if the holder disposes of the
     Capital Securities prior to the record date for the payment of
     Distributions.  See "Certain Federal Income Tax Consequences--Interest 
     Income and Original Issue Discount" and "--Sales of Capital Securities."

          The Company has no current intention of exercising its right
     to defer payments of interest by extending the interest payment
     period on the Junior Subordinated Debentures.  However, should
     the Company elect to exercise such right in the future, the
     market price of the Capital Securities is likely to be affected. 
     A holder that disposes of its Capital Securities during an
     Extension Period, therefore, might not receive the same return on
     its investment as a holder that continues to hold its Capital
     Securities.  In addition, as a result of the existence of the
     Company's right to defer interest payments, the market price of
     the Capital Securities (which represent preferred beneficial
     interests in the Issuer Trust) may be more volatile than the
     market prices of other securities on which original discount
     accrues that are not subject to such deferrals.

     TAX EVENT--SHORTENING OF MATURITY OR REDEMPTION

          Upon the occurrence and during the continuation of a Tax
     Event, the Company has the right, if certain conditions are met,
     (i) to shorten the maturity of the Junior Subordinated Debentures
     to a date not earlier than April 15, 2012 or (ii) to redeem the
     Junior Subordinated Debentures in whole (but not in part) prior
     to July 15, 2007 and within 90 days following the occurrence of
     such Tax Event and therefore cause a mandatory redemption of the
     Capital Securities before July 15, 2007.  Any such redemption
     shall be at a price equal to the Redemption Price (as defined in
     "Description of Exchange Capital Securities--Redemption").

          See "--Possible Tax Law Changes Affecting the Capital
     Securities" below for a discussion of previous legislative
     proposals.  The adoption of similar legislation could give rise
     to a Tax Event,which may permit the Company to shorten the
     maturity of the Junior Subordinated Debentures, resulting in the
     shortening of the maturity of the Capital Securities or which may
     permit the Company to cause a redemption of the Capital
     Securities prior to July 15, 2007.  Prospective investors should
     be aware that the Company's exercise of its right to shorten the
     maturity of the Junior Subordinated Debentures will be a taxable
     event to holders of Capital Securities if the Junior Subordinated
     Debentures are treated as equity for purposes of United States
     federal income taxation before the maturity is shortened.  See
     "Description of Exchange Capital Securities--Conditional Right to
     Shorten Maturity or Redeem upon a Tax Event" and "Description of
     Exchange Junior Subordinated Debentures--Conditional Right to
     Shorten Maturity upon a Tax Event."

          "Tax Event" means the receipt by the Issuer Trust of an
     opinion of counsel to the Company experienced in such matters to
     the effect that, as a result of any amendment to, or change
     (including any announced prospective change) in, the laws (or any
     regulations thereunder) of the United States or any political
     subdivision or taxing authority thereof or therein, or as a
     result of any official administrative pronouncement or judicial
     decision interpreting or applying such laws or regulations, which
     amendment or change is effective or which pronouncement or
     decision is announced on or after the date of issuance of such
     Capital Securities under the Trust Agreement, there is more than
     an insubstantial risk that (i) the Issuer Trust is, or will be
     within 90 days of the date of such opinion, subject to United
     States federal income tax with respect to income received or
     accrued on the Junior Subordinated Debentures, (ii) interest
     payable by the Company on the Junior Subordinated Debentures is
     not, or within 90 days of the date of such opinion, will not be,
     deductible by the Company, in whole or in part, for United States
     federal income tax purposes or (iii) the Issuer Trust is, or will
     be within 90 days of the date of such opinion, subject to more
     than a de minimis amount of other taxes, duties or other
     governmental charges.

     EXCHANGE OF CAPITAL SECURITIES FOR JUNIOR SUBORDINATED DEBENTURES

          The holders of all of the outstanding Common Securities have
     the right at any time to terminate the Issuer Trust and, after
     satisfaction of the liabilities of creditors of the Issuer Trust
     as provided by applicable law, cause the Junior Subordinated
     Debentures to be distributed to the holders of the Trust
     Securities in liquidation of the Issuer Trust, subject to the
     Property Trustee having received an opinion of counsel to the
     effect that such distribution will not be a taxable event to
     holders of Capital Securities.  See "Description of Exchange
     Capital Securities--Liquidation Distribution Upon Termination."

     MARKET PRICES

          There can be no assurance as to the market prices for
     Capital Securities or Junior Subordinated Debentures that may be
     distributed in exchange for Capital Securities if a liquidation
     of the Issuer Trust occurs.  Accordingly, the Capital Securities
     that an investor may purchase, whether pursuant to the offer made
     hereby or in the secondary market, or the Junior Subordinated
     Debentures that a holder of Capital Securities may receive on
     liquidation of the Issuer Trust, may trade at a discount to the
     price that the investor paid to purchase the Capital Securities
     offered hereby.  Because holders of Capital Securities may
     receive Junior Subordinated Debentures on termination of the
     Issuer Trust, prospective purchasers of Exchange Capital
     Securities are also making an investment decision with regard to
     the Exchange Junior Subordinated Debentures and should carefully
     review all the information regarding the Exchange Junior
     Subordinated Debentures contained herein.  See "Description of
     Exchange Junior Subordinated Debentures."

     RIGHTS UNDER THE GUARANTEE

          First Chicago will act as the trustee under the Guarantee
     (the "Guarantee Trustee") and will hold the Guarantee for the
     benefit of the holders of the Capital Securities.  First Chicago
     will also act as Debenture Trustee for the Junior Subordinated
     Debentures and as Property Trustee and First Chicago (Delaware)
     will act as Delaware Trustee under the Trust Agreement.  The
     Guarantee guarantees to the holders of the Capital Securities the
     following payments, to the extent not paid by the Issuer Trust:
     (i) any accumulated and unpaid Distributions required to be paid
     on the Capital Securities, to the extent that the Issuer Trust
     has funds on hand available therefor at such time, (ii) the
     Redemption Price with respect to any Capital Securities called
     for redemption, to the extent that the Issuer Trust has funds on
     hand available therefor at such time and (iii) upon a voluntary
     or involuntary termination, winding-up or liquidation of the
     Issuer Trust (unless the Junior Subordinated Debentures are
     distributed to holders of the Capital Securities), the lesser of
     (a) the aggregate of the Liquidation Amount and all accumulated
     and unpaid Distributions to the date of payment to the extent
     that the Issuer Trust has funds on hand available therefor at
     such time and (b) the amount of assets of the Issuer Trust
     remaining available for distribution to holders of the Capital
     Securities on liquidation of the Issuer Trust after payment of
     creditors of the Issuer Trust as required by applicable law.  The
     Guarantee is subordinate as described under "--Ranking of
     Subordinated Obligations Under the Guarantee and the Junior
     Subordinated Debentures." The holders of not less than a majority
     in aggregate Liquidation Amount of the Capital Securities have
     the right to direct the time, method and place of conducting any
     proceeding for any remedy available to the Guarantee Trustee in
     respect of the Guarantee or to direct the exercise of any trust
     power conferred upon the Guarantee Trustee under the Guarantee. 
     Any holder of the Capital Securities may institute a legal
     proceeding directly against the Company to enforce its rights
     under the Guarantee without first instituting a legal proceeding
     against the Issuer Trust, the Guarantee Trustee or any other
     person or entity.  If the Company were to default on its
     obligation to pay amounts payable under the Junior Subordinated
     Debentures, the Issuer Trust would lack funds for the payment of
     Distributions or amounts payable on redemption of the Capital
     Securities or otherwise and, in such event, holders of the
     Capital Securities would not be able to rely upon the Guarantee
     for payment of such amounts.  Instead, in the event a Debenture
     Event of Default shall have occurred and be continuing and such
     event is attributable to the failure of the Company to pay
     interest on or principal of the Junior Subordinated Debentures on
     the payment date on which such payment is due and payable, then a
     holder of Capital Securities may institute a legal proceeding
     directly against the Company for enforcement of payment to such
     holder of the principal of or interest on such Junior
     Subordinated Debentures having a principal amount equal to the
     aggregate Liquidation Amount of the Capital Securities of such
     holder (a "Direct Action").  In connection with such Direct
     Action, the Company will have a right of set-off under the Junior
     Subordinated Indenture to the extent of any payment made by the
     Company to such holder of Capital Securities in the Direct
     Action.  Except as described herein, holders of Capital
     Securities will not be able to exercise directly any other remedy
     available to the holders of the Junior Subordinated Debentures or
     assert directly any other rights in respect of the Junior
     Subordinated Debentures.  See "Description of Exchange
     Securities--Description of Exchange Junior Subordinated
     Debentures--Enforcement of Certain Rights by Holders of Capital
     Securities," "--Debenture Events of Default" and "Description of
     Exchange Guarantee." The Trust Agreement provides that each
     holder of Capital Securities by acceptance thereof agrees to the
     provisions of the Guarantee and the Junior Subordinated
     Indenture.

     LIMITED VOTING RIGHTS

          Holders of Capital Securities will generally have limited
     voting rights relating only to the modification of the Capital
     Securities and the exercise of the Issuer Trust's rights as
     holder of Junior Subordinated Debentures and the Guarantee. 
     Holders of Capital Securities will not be entitled to appoint,
     remove or replace the Property Trustee or the Delaware Trustee
     except upon the occurrence of certain events described herein. 
     The Property Trustee and the holders of all of the Common
     Securities may amend the Trust Agreement without the consent of
     holders of Capital Securities to ensure that the Issuer Trust
     will be classified for United States federal income tax purposes
     as a grantor trust.  See "Description of Exchange Capital
     Securities--Voting Rights; Amendment of Trust Agreement" and
     "--Removal of Issuer Trustees; Appointment of Successors."

     CONSEQUENCES OF A FAILURE TO EXCHANGE ORIGINAL CAPITAL SECURITIES

          The Original Capital Securities have not been registered
     under the Securities Act or any state securities laws and
     therefore may not be offered, sold or otherwise transferred
     except in compliance with the registration requirements of the
     Securities Act and any other applicable securities laws, or
     pursuant to an exemption therefrom or in a transaction not
     subject thereto, and in each case in compliance with certain
     other conditions and restrictions.  Original Capital Securities
     which remain outstanding after consummation of the Exchange Offer
     will continue to bear a legend reflecting such restrictions on
     transfer.  In addition, upon consummation of the Exchange Offer,
     holders of Original Capital Securities which remain outstanding
     will not be entitled to any rights to have such Original Capital
     Securities registered under the Securities Act or to any similar
     rights under the Registration Rights Agreement (subject to
     certain limited exceptions).  The Company and the Issuer Trust do
     not intend to register under the Securities Act any Original
     Capital Securities which remain outstanding after consummation of
     the Exchange Offer (subject to such limited exceptions, if
     applicable).  To the extent that Original Capital Securities are
     tendered and accepted in the Exchange Offer, a holder's ability
     to sell untendered Original Capital Securities could be adversely
     affected.

          The Exchange Capital Securities and any Original Capital
     Securities which remain outstanding after consummation of the
     Exchange Offer will vote together as a single class for purposes
     of determining whether holders of the requisite percentage in
     outstanding Liquidation Amount thereof have taken certain actions
     or exercised certain rights under the Declaration.  See
     "Description of Exchange Securities Description of Exchange
     Capital Securities Voting Rights; Amendment of the Declaration."

          The Original Capital Securities provide, among other things,
     that, if a registration statement relating to the Exchange Offer
     has not been filed by October 13, 1997 and declared effective by
     December 12, 1997, the Distribution rate borne by the Original
     Capital Securities will increase by 0.25% per annum until such
     registration statement has been filed or declared effective, as
     the case may be.  Upon consummation of the Exchange Offer,
     holders of Original Capital Securities will not be entitled to
     any increase in the Distribution rate thereon or any further
     registration rights under the Registration Rights Agreement,
     except under limited circumstances.  See "Description of Original
     Securities."

     ABSENCE OF PUBLIC MARKET

          The Original Capital Securities were issued to, and the
     Company believes such securities are currently owned by, a
     relatively small number of beneficial owners.  The Original
     Capital Securities have not been registered under the Securities
     Act and will be subject to restrictions on transferability if
     they are not exchanged for the Exchange Capital Securities. 
     Although the Exchange Capital Securities may be resold or
     otherwise transferred by the holders (who are not affiliates of
     the Company or the Issuer Trust) without compliance with the
     registration requirements under the Securities Act, they will
     constitute a new issue of securities with no established trading
     market.  The Company and the Issuer Trust have been advised by
     the Initial Purchasers that the Initial Purchasers presently
     intend to make a market in the Exchange Capital Securities. 
     However, the Initial Purchasers are not obligated to do so and
     any market-making activity with respect to the Exchange Capital
     Securities may be discontinued at any time without notice.  In
     addition, such market-making activity will be subject to the
     limits imposed by the Securities Act and the Exchange Act and may
     be limited during the Exchange Offer.  Accordingly, no assurance
     can be given that an active public or other market will develop
     for the Exchange Capital Securities or the Original Capital
     Securities, or as to the liquidity of or the trading market for
     the Exchange Capital Securities or the Original Capital
     Securities.  If an active public market does not develop, the
     market price and liquidity of the Exchange Capital Securities may
     be adversely affected.

          If a public trading market develops for the Exchange Capital
     Securities, future trading prices will depend on many factors,
     including, among other things, prevailing interest rates, the
     financial condition of the Company and its subsidiaries, and the
     market for similar securities.  Depending on these and other
     factors, the Exchange Capital Securities may trade at a discount.

          Notwithstanding the registration of the Exchange Capital
     Securities in the Exchange Offer, holders who are "affiliates"
     (as defined under Rule 405 of the Securities Act) of the Company
     or the Issuer Trust may publicly offer for sale or resell the
     Exchange Capital Securities only in compliance with the
     provisions of Rule 144 under the Securities Act.

          Each broker-dealer that receives Exchange Capital Securities
     for its own account in exchange for Original Capital Securities,
     where such Original Capital Securities were acquired by such
     broker-dealer as a result of market-making activities or other
     trading activities, must acknowledge that it will deliver a
     prospectus in connection with any resale of such Exchange Capital
     Securities.  See "Plan of Distribution."

     POSSIBLE TAX LAW CHANGES AFFECTING THE CAPITAL SECURITIES

          On February 6, 1997, as part of the fiscal budget submitted
     to Congress, the Clinton Administration proposed certain changes
     to federal income tax law which would, among other things,
     generally treat as equity, for federal income tax purposes,
     certain debt obligations, such as the Junior Subordinated
     Debentures, that were issued on or after the date of "first
     committee action" (the "Clinton Proposal").  The Junior
     Subordinated Debentures were issued prior to the date of first
     committee action.  The Clinton Proposal was not included in the
     tax legislation signed into law by President Clinton on August 5,
     1997.  There can be no assurance, however, that similar
     legislation enacted in the future will not adversely affect the
     tax treatment of the Junior Subordinated Debentures, which could
     result in the redemption of the Junior Subordinated Debentures by
     the Company and the distribution of the resulting cash in
     redemption of the Capital Securities or a shortening of the
     maturity of the Capital Securities.  See "Description of Exchange
     Junior Subordinated Debentures Redemption" and "Description of
     Exchange Capital Securities Redemption." See also "Certain
     Federal Income Tax Consequences Possible Tax Law Changes."

     EXCHANGE OFFER PROCEDURES

          Subject to the conditions set forth under "The Exchange
     Offer Conditions to the Exchange Offer," delivery of Exchange
     Capital Securities in exchange for Original Capital Securities
     tendered and accepted for exchange pursuant to the Exchange Offer
     will be made only after timely receipt by the Exchange Agent of
     (i) certificates for Original Capital Securities or a book-entry
     confirmation of a book-entry transfer of Original Capital
     Securities into the Exchange Agent's account at DTC, including an
     Agent's Message (as defined under "The Exchange Offer Acceptance
     for Exchange and Issuance of Exchange Capital Securities") if the
     tendering holder does not deliver a Letter of Transmittal, (ii) a
     completed and signed Letter of Transmittal (or facsimile
     thereof), with any required signature guarantees, or, in the case
     of a book-entry transfer, an Agent's Message in lieu of the
     Letter of Transmittal, and (iii) any other documents required by
     the Letter of Transmittal.  Therefore, holders of Original
     Capital Securities desiring to tender such Original Capital
     Securities in exchange for Exchange Capital Securities should
     allow sufficient time to ensure timely delivery.  Neither the
     Company nor the Issuer Trust is under a duty to give notification
     of defects or irregularities with respect to the tenders of
     Original Capital Securities for exchange. 

          Each broker-dealer that receives Exchange Securities for its
     own account in exchange for Securities, where such Securities
     were acquired by such broker-dealer as a result of market-making
     activities or other trading activities, must acknowledge that it
     will deliver a prospectus in connection with any resale of such
     Exchange Securities.  See "Plan of Distribution."


                              HSB GROUP, INC.

     GENERAL

          HSB Group, Inc. is a newly formed holding company which owns
     directly or indirectly, a number of insurance and engineering
     service subsidiaries which specialize in insuring against losses
     from accidents to boilers, pressure vessels and mechanical and
     electrical machinery and equipment, and in providing related
     engineering services.  HSB Group's operations are divided into
     three industry segments insurance, engineering services and
     investments.

          The most significant subsidiary of the Company is Hartford
     Steam Boiler, an insurance company chartered under the laws of
     the State of Connecticut in 1866.  Hartford Steam Boiler is the
     largest writer of equipment breakdown insurance in North America
     and is establishing a presence in the engineering insurance
     market outside of North America.  In 1996, earned premiums for
     HSB Group's insurance products were $448.6 million, approximately
     81.7 percent of the revenues of HSB Group.

     EQUIPMENT BREAKDOWN INSURANCE

          Hartford Steam Boiler is the largest writer of equipment
     breakdown insurance in North America and is establishing a
     presence in the engineering insurance market outside of North
     America.  Based on gross earned premium, Hartford Steam Boiler's
     U.S. market share, at approximately 40 percent, has remained
     fairly stable over the past ten years.

          Equipment breakdown insurance provides for the
     indemnification of the policyholder for financial loss resulting
     from destruction or damage to an insured boiler, pressure vessel,
     or other item of machinery or equipment caused by an accident. 
     This financial loss can include the cost to repair or replace the
     damaged equipment (property damage), and product spoilage, lost
     profits and expenses to avert lost profits (business
     interruption) stemming from an accident.  This heavy emphasis on
     loss prevention historically has had the dual effect of
     increasing underwriting and inspection expenses, while reducing
     loss and loss adjustment expenses.  In this regard, the Company
     distinguishes itself from other insurance suppliers by providing
     a high level of loss prevention, failure analysis and other
     engineering services with its insurance products.  An important
     ancillary benefit for the policyholder is that the inspection
     performed by the Company's inspector on a boiler, pressure
     vessel, or other piece of equipment, as part of the insurance
     process, is normally accepted by state and other regulatory
     jurisdictions for their certification purposes.  Without a
     certificate of inspection by the insurance carrier or another
     inspection agency, policyholders cannot legally operate many
     types of equipment.

          The Company also writes all risk property insurance for
     risks with significant machinery and equipment exposures, in
     addition to its more traditional boiler and machinery products. 
     The all risk line is marketed to customers with equipment and
     machinery exposures, such as electric utilities, where
     sophisticated engineering services are important to loss
     prevention and control.


     ENGINEERING AND INSPECTION SERVICES

          Separate divisions of the Company's Engineering Department
     provide quality assurance services, training for nondestructive
     testing, inspections to code standards of the American Society of
     Mechanical Engineers (ASME), ISO certification services and other
     specialized consulting and inspection services related to the
     design and application of boilers, pressure vessels, and many
     other types of equipment for domestic and foreign equipment
     manufacturers and their customers.  The Company is the largest
     Authorized Inspection Agency for ASME codes in the world.  In
     addition, the Company's Engineering Department focuses on
     researching and developing potential new products and services,
     and new markets for current services.  In 1996, net engineering
     services revenues were $55.8 million, approximately 10.2 percent
     of the Company's revenues.

     STRATEGY; RECENT HISTORY

          The Company's strategy is to maintain its market share in
     North America and expand overseas through leveraging its
     engineering expertise in assessing and managing risk to provide
     insurance products.  The Company is a multi-national company
     operating in North American, European, and Asian markets. 
     Currently, the Company's principal market is the United States. 
     However, the Company seeks to become a stronger competitor in
     international markets as it believes that there is significant
     opportunity for profitable growth overseas.  In 1996 the revenues
     and pre-tax income associated with operations outside of the
     United States were approximately 18.9 percent and 28.3 percent,
     respectively.  Identifiable assets associated with operations
     outside of the United States are approximately 23.1 percent of
     the consolidated amount.  The Company conducts it business in
     Canada through its subsidiary, The Boiler Inspection and
     Insurance Company of Canada.  Insurance for risks located in
     countries other than the United States and Canada is written by
     HSB Engineering Insurance Limited (HSB EIL).  In December 1994,
     the Company purchased the remaining 50% interest in HSB EIL's
     parent company, Engineering Insurance Group (EIG) from General
     Reinsurance Corporation.

          Effective December 1, 1996 the Company increased its
     membership participation in Industrial Risk Insurers ("IRI") from
     14 percent to 23.5 percent.  IRI is a voluntary, unincorporated
     joint underwriting association, comprised of property casualty
     insurance members, which provides property insurance for "highly
     protected risks" larger manufacturing, processing, and industrial
     businesses which have invested in protection against loss through
     the use of sprinklers and other means.  The Company has increased
     its share because it believes that participation in the IRI is an
     opportunity to apply the Company's underwriting, engineering and
     reinsurance skill sets to a large block of business and to
     potentially provide a quick turnaround of IRI's underwriting
     results with only a limited capital outlay.

          In January 1996, the Company completed the formation of
     Radian International 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, and Dow contributed
     the assets of Dow Environmental, Inc., its wholly-owned
     subsidiary, as well as access to certain of its technologies
     which help support the businesses expected to be conducted by the
     joint venture company.  Radian International currently is 40
     percent owned by Radian Corporation and 60 percent owned by Dow
     Environmental Inc.  In 1996, the Company's share of the joint
     venture's results are recorded as equity in Radian rather than
     consolidated with the Company's net engineering services revenue
     and other income statement accounts.  The joint venture agreement
     with Dow provided HSB the option to put its share of the joint
     venture to Dow any time during the period from December 31, 1997
     to December 31, 1998 upon giving appropriate notice.  On July 28,
     1997 the HSB Board of Directors ratified management's decision to
     put its share of Radian International to Dow on or about January
     1, 1998 for approximately $145 million.  This amount is not
     subject to any material adjustment due to the future operating
     results of Radian International; therefore this will result in a
     pre-tax gain of approximately $60 million.  Due to this decision,
     the results of Radian International have been classified as
     discontinued operations.  HSB's share of Radian International's
     results has been immaterial to the consolidated results during
     the first six months of 1997.

          The Company's principal executive offices are located at One
     State Street, Hartford, Connecticut 06102.  The Company's
     telephone number is (860) 722-1866.

     CORPORATE STRUCTURE; NEWLY ORGANIZED HOLDING COMPANY

          The Company was recently incorporated to become the holding
     company of, and the direct owner of, Hartford Steam Boiler and
     certain of its subsidiaries.

          On June 24, 1997, (the "Effective Time"), each share of
     common stock outstanding of Hartford Steam Boiler immediately
     prior to the Effective Time was exchanged for one share of common
     stock of the Company.  Each share of preferred stock of Hartford
     Steam Boiler outstanding immediately prior to the Effective Time
     was exchanged for one share of preferred stock of the Company
     (which series has substantially identical rights and preferences
     as Hartford Steam Boiler preferred stock) (the "Share Exchange")
     for the sole purpose of making the Company the holding company
     and sole stockholder of Hartford Steam Boiler and certain other
     subsidiaries.

          The holding company was formed in order to achieve greater
     operating and financial flexibility in connection with certain
     investments, business operations and financing activities. 
     Holding company structures are frequently used when an
     organization conducts regulated and unregulated lines of
     businesses and are commonly found in the insurance industry.

          The consolidated financial position and consolidated results
     of operations of the Company are substantially identical to those
     of Hartford Steam Boiler immediately prior to the exchange. 
     Complete pro forma and comparative financial information
     regarding the Company and its consolidated subsidiaries giving
     effect to the Share Exchange has not been included herein because
     immediately following the Effective Time of the Share Exchange,
     the consolidated financial statements for the Company was
     substantially the same as the consolidated financial statements
     of Hartford Steam Boiler immediately prior to the Share Exchange. 


         SELECTED CONSOLIDATED FINANCIAL DATA AND OTHER INFORMATION

          The selected consolidated financial data set forth in the
     table below for each of the years in the five year period ended
     December 31, 1996 have been derived from Hartford Steam Boiler's
     consolidated financial statements and Hartford Steam Boiler's
     1996 Annual Report on Form 10-K/A, each of which is incorporated
     by reference herein.  The Company is a newly formed company
     created for the purpose of making the Company the holding company
     and sole stockholder of Hartford Steam Boiler and certain other
     subsidiaries.  The Share Exchange creating the new holding
     company structure was consummated on June 24, 1997.  The
     consolidated financial position and consolidated results of
     operations of the Company are substantially identical to those of
     Hartford Steam Boiler immediately prior to the Share Exchange. 
     See "HSB Group, Inc. Corporate Structure; Newly Organized Holding
     Company." The data presented for the six month periods ending
     June 30, 1997 and 1996 have been derived from unaudited
     consolidated financial statements included in the Company's
     Quarterly Report on Form 10-Q and Hartford Steam Boiler's Quarterly
     Report on Form 10-Q for such periods.  The data presented for the 
     periods ending June 30, 1997 and 1996 have been prepared on the 
     same basis as the audited consolidated financial statements and 
     include all adjustments, consisting of normal, recurring accruals 
     that the Company considers necessary for a fair presentation of 
     the financial position and results of operations for the periods 
     presented. Operating results for the period ended June 30, 1997 are 
     not necessarily indicative of the results that may be expected for
     the fiscal year ended December 31, 1997.  The selected financial
     data presented below should be read in conjunction with the
     Company's consolidated financial statements and notes thereto and
     other information appearing in Hartford Steam Boiler's 1996
     Annual Report on Form 10-K/A, and with the unaudited financial
     statements in the Company's Quarterly Report on Form 10-Q for the
     quarter ended June 30, 1997, each of which is incorporated herein
     by reference.  All numbers have been restated to eliminate the
     effect of Radian International and reflect it as a discontinued
     operation.

                               HSB CAPITAL I

          The Issuer Trust is a statutory business trust created under
     Delaware law pursuant to (i) the Trust Agreement executed by the
     Company, as Depositor, First Chicago, as Property Trustee, and
     First Chicago (Delaware), as Delaware Trustee, and (ii) the
     filing of a certificate of trust with the Delaware Secretary of
     State.  The Issuer Trust's business and affairs are conducted by
     its trustees: First Chicago, as Property Trustee, and First
     Chicago, (Delaware) as Delaware Trustee.  In addition, three
     individuals who are employees or officers of or affiliated with
     the holder of a majority of the Common Securities will act as
     administrators with respect to the Issuer Trust (the
     "Administrators").  The Administrators will be selected by the
     holders of the Common Securities.  See "Description of Capital
     Securities Miscellaneous." The Issuer Trust exists for the
     exclusive purposes of (i) issuing and selling the Trust
     Securities, (ii) using the proceeds from the sale of Trust
     Securities to acquire Junior Subordinated Debentures issued by
     the Company and (iii) engaging in only those other activities
     necessary or incidental thereto (such as registering the transfer
     of the Trust Securities).  Accordingly, the Junior Subordinated
     Debentures and the right to reimbursement of expenses under the
     related Expense Agreement will be the sole assets of the Issuer
     Trust, and payments under the Junior Subordinated Debentures and
     the related Expense Agreement will be the sole revenue of the
     Issuer Trust.

          All of the Common Securities will be owned by the Company. 
     The Common Securities will rank pari passu, and payments will be
     made thereon pro rata, with the Capital Securities, except that
     upon the occurrence and continuance of an Event of Default under
     the Trust Agreement resulting from a Debenture Event of Default
     under the Junior Subordinated Indenture, the rights of the
     holders of the Common Securities to payment in respect of
     Distributions and payments upon liquidation, redemption or
     otherwise will be subordinated to the rights of the holders of
     the Capital Securities.  See "Description of Capital
     Securities Subordination of Common Securities." The Company will
     acquire Common Securities in an aggregate liquidation amount
     equal to 3% of the total capital of the Issuer Trust.  The Issuer
     Trust has a term of 31 years, but may terminate earlier as
     provided in the Trust Agreement.  The principal executive office
     of the Issuer Trust is One State Street, Hartford, Connecticut
     06102, Attention: Corporate Secretary, and its telephone number
     is (860) 722-1866.

                     RATIO OF EARNINGS TO FIXED CHARGES
                 AND PREFERRED STOCK DIVIDEND REQUIREMENTS

          The ratio of earnings to fixed charges and preferred stock
     dividend requirements for the Company including its consolidated
     subsidiaries is computed by dividing earnings by fixed charges
     and preferred stock dividend requirements.  Earnings consist of
     income before income taxes plus fixed charges.  Fixed charges
     consist of interest expense, capitalized interest, one-third (the
     portion deemed representative of the interest factor) of net
     rents and expenses under long-term leases and preferred stock
     dividend requirements which consist of the pre-tax earnings which
     would be required to cover dividends required to be paid on the
     Company's majority-owned subsidiary's outstanding preferred
     stock.  The following table sets forth the ratio of earnings to
     fixed charges for the Company and its consolidated subsidiaries
     for the periods indicated.

                              USE OF PROCEEDS

          Neither the Company nor the Issuer Trust will receive any
     cash proceeds from the issuance of the Exchange Capital
     Securities and the Exchange Guarantee offered hereby.  In
     consideration for issuing the Exchange Capital Securities in
     exchange for Original Capital Securities as described in this
     Prospectus, the Issuer Trust will receive Original Capital
     Securities in like Liquidation Amount.  The Original Capital
     Securities surrendered in exchange for the Exchange Capital
     Securities will be retired and canceled.

          The proceeds to the Issuer Trust (without giving effect to
     expenses of the offering payable by the Company) from the
     offering of the Original Capital Securities was $108,861,500. 
     All of the proceeds from the sale of the Original Capital
     Securities were invested by the Issuer Trust in the Original
     Junior Subordinated Debentures.  The Company intends that the net
     proceeds from the sale of the Original Junior Subordinated
     Debentures will be used for general corporate purposes which may
     include, without limitation, repurchases of the Company's common
     stock, funding investments in, or extensions of credit to, the
     Company's subsidiaries, repayment of outstanding indebtedness and
     maturing obligations, and financing possible future acquisitions. 
     As of the date of this Prospectus, the Company has not entered
     into any material agreements or understandings with respect to
     any potential acquisition.  The precise amount and timing of the
     application of such net proceeds used for these purposes will
     depend on market prices for the Company's common stock and the
     funding requirements and availability of other funds to the
     Company and its subsidiaries.

                               CAPITALIZATION

     capitalization of the Company and its subsidiaries as of June 30,
     1997 as adjusted to give effect to the issuance of $110 million

     The issuance of the Exchange Capital Securities in the Exchange
     Offer will have  no effect on the capitalization of the Company.

     consolidated financial statements and notes thereto of the
     Company and its subsidiaries incorporated herein by reference.

                            ACCOUNTING TREATMENT

          For financial reporting purposes, the Issuer Trust will be
     treated as a subsidiary of the Company and, accordingly, the
     accounts of the Issuer Trust will be included in the consolidated
     financial statements of the Company.  The Capital Securities will
     be presented as a separate line item in the consolidated balance
     sheets of the Company, entitled "Company Obligated Mandatorily
     Redeemable Capital Securities of Subsidiary Trust Holding Solely
     Junior Subordinated Deferrable Interest Debentures of the
     Company" and appropriate disclosures about the Capital
     Securities, the Guarantee and the Junior Subordinated Debentures
     will be included in the notes to the Company's consolidated
     financial statements.  For financial reporting purposes, the
     Company will record Distributions payable on the Capital
     Securities as an expense in the Company's consolidated statements
     of income.


                        RATING OF CAPITAL SECURITIES

          The Capital Securities have been assigned a rating of "A-" 
     by Standard and Poor's Ratings Services and "A-" by Duff
     & Phelps Credit Rating Co.  A security rating is not a
     recommendation to buy, sell or hold securities and may be subject
     to revision or withdrawal at any time by the assigning rating
     organization.  There is no assurance that any rating will remain
     in effect for any given period of time or that any rating will
     not be revised or withdrawn entirely by a assigning rating
     organization in the future if in its judgment circumstances so
     warrant.


                             THE EXCHANGE OFFER

     PURPOSE OF THE EXCHANGE OFFER

          In connection with the sale of the Original Capital
     Securities, the Company and the Issuer Trust entered into the
     Registration Rights Agreement with the Initial Purchasers,
     pursuant to which the Company and the Issuer Trust agreed to file
     and to use their reasonable efforts to cause to become effective
     with the Commission a registration statement with respect to the
     exchange of the Original Capital Securities for capital
     securities with terms identical in all material respects to the
     terms of the Original Capital Securities.  A copy of the
     Registration Rights Agreement has been filed as an Exhibit to the
     Registration Statement of which this Prospectus is a part.

          The Exchange Offer is being made to satisfy the contractual
     obligations of the Company and the Issuer Trust under the
     Registration Rights Agreement.  The form and terms of the
     Exchange Capital Securities are the same as the form and terms of
     the Original Capital Securities except that the Exchange Capital
     Securities have been registered under the Securities Act and will
     not be subject to certain restrictions on transfer applicable to
     the Original Capital Securities, and will not provide for any
     increase in the Distribution rate thereon.  In that regard, the
     Original Capital Securities provide, among other things, that, if
     a registration statement relating to the Exchange Offer has not
     been filed by October 13, 1997 and declared effective by December
     12, 1997, the Distribution rate borne by the Original Capital
     Securities will increase by 0.25% per annum until such
     registration statement is filed or declared effective, as the
     case may be.  Upon consummation of the Exchange Offer, holders of
     Original Capital Securities will not be entitled to any increase
     in the Distribution rate thereon or any further registration
     rights under the Registration Rights Agreement, except under
     limited circumstances.  See "Risk Factors Consequences of a
     Failure to Exchange Original Capital Securities" and "Description
     of Original Securities."

          The Exchange Offer is not being made to, nor will the Issuer
     Trust accept tenders for exchange from, holders of Original
     Capital Securities in any jurisdiction in which the Exchange
     Offer or the acceptance thereof would not be in compliance with
     the securities or blue sky laws of such jurisdiction.

          Each broker-dealer that receives Exchange Securities for its
     own account in exchange for Securities, where such Securities
     were acquired by such broker-dealer as a result of market-making
     activities or other trading activities, must acknowledge that it
     will deliver a prospectus in connection with any resale of such
     Exchange Securities.  See "Plan of Distribution."

          Unless the context requires otherwise, the term "holder"
     with respect to the Exchange Offer means any person in whose name
     the Original Capital Securities are registered on the books of
     the Issuer Trust or any other person who has obtained a properly
     completed bond power from the registered holder, or any person
     whose Original Capital Securities are held of record by The
     Depository Trust Company ("DTC") who desires to deliver such
     Original Capital Securities by book-entry transfer at DTC.

          Pursuant to the Exchange Offer, the Company will exchange as
     soon as practicable after the date hereof, the Original Guarantee
     for the Exchange Guarantee and the Original Junior Subordinated
     Debentures, in an amount corresponding to the Original Capital
     Securities accepted for exchange, for a like aggregate principal
     amount of the Exchange Junior Subordinated Debentures.  The
     Exchange Guarantee and Exchange Junior Subordinated Debentures
     have been registered under the Securities Act.

     TERMS OF THE EXCHANGE OFFER

          The Issuer Trust hereby offers, upon the terms and subject
     to the conditions set forth in this Prospectus and in the
     accompanying Letter of Transmittal, to exchange up to
     $110,000,000 aggregate Liquidation Amount of Exchange Capital
     Securities for a like aggregate Liquidation Amount of Original
     Capital Securities properly tendered on or prior to the
     Expiration Date and not properly withdrawn in accordance with the
     procedures described below.  The Issuer Trust will issue,
     promptly after the Expiration Date, an aggregate Liquidation
     Amount of up to $110,000,000 of Exchange Capital Securities in
     exchange for a like principal amount of outstanding Original
     Capital Securities tendered and accepted in connection with the
     Exchange Offer.  Holders may tender their Original Capital
     Securities in whole or in part in a Liquidation Amount of not
     less than $1,000 Liquidation Amount (one Capital Security).

          The Exchange Offer is not conditioned upon any minimum
     Liquidation Amount of Original Capital Securities being tendered. 
     As of the date of this Prospectus, $110,000,000 aggregate
     Liquidation Amount of the Original Capital Securities is
     outstanding.

          Holders of Original Capital Securities do not have any
     appraisal or dissenters' rights in connection with the Exchange
     Offer.  Original Capital Securities which are not tendered for or
     are tendered but not accepted in connection with the Exchange
     Offer will remain outstanding and be entitled to the benefits of
     the Declaration, but will not be entitled to any further
     registration rights under the Registration Rights Agreement,
     except under limited circumstances.  See "Risk
     Factors Consequences of a Failure to Exchange Original Capital
     Securities" and "Description of Original Securities."

          If any tendered Original Capital Securities are not accepted
     for exchange because of an invalid tender, the occurrence of
     certain other events set forth herein or otherwise, certificates
     for any such unaccepted Original Capital Securities will be
     returned, without expense, to the tendering holder thereof
     promptly after the Expiration Date.

          Holders who tender Original Capital Securities in connection
     with the Exchange Offer will not be required to pay brokerage
     commissions or fees or, subject to the instructions in the Letter
     of Transmittal, transfer taxes with respect to the exchange of
     Original Capital Securities in connection with the Exchange
     Offer.  The Company will pay all charges and expenses, other than
     certain applicable taxes described below, in connection with the
     Exchange Offer.  See " Fees and Expenses."

          NEITHER THE COMPANY, THE BOARD OF DIRECTORS OF THE COMPANY
     NOR ANY TRUSTEE OF THE ISSUER TRUST MAKES ANY RECOMMENDATION TO
     HOLDERS OF ORIGINAL CAPITAL SECURITIES AS TO WHETHER TO TENDER OR
     REFRAIN FROM TENDERING ALL OR ANY PORTION OF THEIR ORIGINAL
     CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER.  IN ADDITION,
     NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. 
     HOLDERS OF ORIGINAL CAPITAL SECURITIES MUST MAKE THEIR OWN
     DECISIONS WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER AND,
     IF SO, THE AGGREGATE AMOUNT OF ORIGINAL CAPITAL SECURITIES TO
     TENDER BASED ON SUCH HOLDERS' OWN FINANCIAL POSITIONS AND
     REQUIREMENTS.

     EXPIRATION DATE; EXTENSIONS; AMENDMENTS

          The term "Expiration Date" means 5:00 p.m., New York City
     time, on _______, 1997 unless the Exchange Offer is extended by
     the Company or the Issuer Trust (in which case the term
     "Expiration Date" shall mean the latest date and time to which
     the Exchange Offer is extended).

          The Company and the Issuer Trust expressly reserve the right
     in their sole and absolute discretion, subject to applicable law,
     at any time and from time to time, (i) to delay the acceptance of
     the Original Capital Securities for exchange, (ii) to terminate
     the Exchange Offer (whether or not any Original Capital
     Securities have theretofore been accepted for exchange) if the
     Issuer Trust determines, in its sole and absolute discretion,
     that any of the events or conditions referred to under
     " Conditions to the Exchange Offer" have occurred or exist or
     have not been satisfied, (iii) to extend the Expiration Date of
     the Exchange Offer and retain all Original Capital Securities
     tendered pursuant to the Exchange Offer, subject, however, to the
     right of holders of Original Capital Securities to withdraw their
     tendered Original Capital Securities as described under
     " Withdrawal Rights," and (iv) to waive any condition or
     otherwise amend the terms of the Exchange Offer in any respect. 
     If the Exchange Offer is amended in a manner determined by the
     Company and the Issuer Trust to constitute a material change, or
     if the Company and the Issuer Trust waive a material condition of
     the Exchange Offer, the Company and the Issuer Trust will
     promptly disclose such amendment by means of a prospectus
     supplement that will be distributed to the holders of the
     Original Capital Securities, and the Company and the Issuer Trust
     will extend the Exchange Offer to the extent required by Rule
     14e-1 under the Exchange Act.

          Any such delay in acceptance, extension, termination or
     amendment will be followed promptly by oral or written notice
     thereof to the Exchange Agent and by making a public announcement
     thereof, and such announcement in the case of an extension will
     be made no later than 9:00 a.m., New York City time, on the next
     business day after the previously scheduled Expiration Date. 
     Without limiting the manner in which the Company and the Issuer
     Trust may choose to make any public announcement and subject to
     applicable law, the Company and the Issuer Trust shall have no
     obligation to publish, advertise or otherwise communicate any
     such public announcement other than by issuing a release to an
     appropriate news agency.

     ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF EXCHANGE CAPITAL
     SECURITIES

          Upon the terms and subject to the conditions of the Exchange
     Offer, the Issuer Trust will exchange Exchange Capital Securities
     for Original Capital Securities validly tendered and not
     withdrawn (pursuant to the withdrawal rights described under
     "--Withdrawal Rights") promptly after the Expiration Date.

          Subject to the conditions set forth under "--Conditions to
     the Exchange Offer," delivery of Exchange Capital Securities in
     exchange for Original Capital Securities tendered and accepted
     for exchange pursuant to the Exchange Offer will be made only
     after timely receipt by the Exchange Agent of (i) certificates
     for Original Capital Securities or a book-entry confirmation of a
     book-entry transfer of Original Capital Securities into the
     Exchange Agent's account at DTC, including an Agent's Message if
     the tendering holder does not deliver a Letter of Transmittal,
     (ii) a completed and signed Letter of Transmittal (or facsimile
     thereof), with any required signature guarantees, or, in the case
     of a book-entry transfer, an Agent's Message in lieu of the
     Letter of Transmittal, and (iii) any other documents required by
     the Letter of Transmittal.  Accordingly, the delivery of Exchange
     Capital Securities might not be made to all tendering holders at
     the same time, and will depend upon when certificates for
     Original Capital Securities, book-entry confirmations with
     respect to Original Capital Securities and other required
     documents are received by the Exchange Agent.

          The term "book-entry confirmation" means a timely
     confirmation of a book-entry transfer of Original Capital
     Securities into the Exchange Agent's account at DTC.  See
     " Procedures for Tendering Original Capital Securities Book Entry
     Transfer." The term "Agent's Message" means a message,
     transmitted by DTC to and received by the Exchange Agent and
     forming a part of a book-entry confirmation, which states that
     DTC has received an express acknowledgment from the tendering
     participant, which acknowledgment states that such participant
     has received and agrees to be bound by the Letter of Transmittal
     and that the Issuer Trust and the Company may enforce such Letter
     of Transmittal against such participant.

          Subject to the terms and conditions of the Exchange Offer,
     the Company and the Issuer Trust will be deemed to have accepted
     for exchange, and thereby exchanged, Original Capital Securities
     validly tendered and not withdrawn as, if and when the Issuer
     Trust gives oral or written notice to the Exchange Agent of the
     Company's and the Issuer Trust's acceptance of such Original
     Capital Securities for exchange pursuant to the Exchange Offer. 
     The Exchange Agent will act as agent for the Company and the
     Issuer Trust for the purpose of receiving tenders of Original
     Capital Securities, Letters of Transmittal and related documents,
     and as agent for tendering holders for the purpose of receiving
     Original Capital Securities, Letters of Transmittal and related
     documents and transmitting Exchange Capital Securities which will
     not be held in global form by DTC or a nominee of DTC to validly
     tendering holders.  Such exchange will be made promptly after the
     Expiration Date.  If for any reason whatsoever, acceptance for
     exchange or the exchange of any Original Capital Securities
     tendered pursuant to the Exchange Offer is delayed (whether
     before or after the Company's and the Issuer Trust's acceptance
     for exchange of Original Capital Securities) or the Company and
     the Issuer Trust extend the Exchange Offer or are unable to
     accept for exchange or exchange Original Capital Securities
     tendered pursuant to the Exchange Offer, then, without prejudice
     to the Company's and the Issuer Trust's rights set forth herein,
     the Exchange Agent may, nevertheless, on behalf of the Company
     and the Issuer Trust and subject to Rule 14e-1(c) under the
     Exchange Act, retain tendered Original Capital Securities and
     such Original Capital Securities may not be withdrawn except to
     the extent tendering holders are entitled to withdrawal rights as
     described under "--Withdrawal Rights."

          Pursuant to an Agent's Message or a Letter of Transmittal, a
     holder of Original Capital Securities will represent, warrant and
     agree in the Letter of Transmittal that it has full power and
     authority to tender, exchange, sell, assign and transfer Original
     Capital Securities, that the Issuer Trust will acquire good,
     marketable and unencumbered title to the tendered Original
     Capital Securities, free and clear of all liens, restrictions,
     charges and encumbrances, and the Original Capital Securities
     tendered for exchange are not subject to any adverse claims or
     proxies.  The holder also will warrant and agree that it will,
     upon request, execute and deliver any additional documents deemed
     by the Issuer Trust or the Exchange Agent to be necessary or
     desirable to complete the exchange, sale, assignment, and
     transfer of the Original Capital Securities tendered pursuant to
     the Exchange Offer.

     PROCEDURES FOR TENDERING ORIGINAL CAPITAL SECURITIES

          VALID TENDER

          Except as set forth below, in order for Original Capital
     Securities to be validly tendered by book-entry transfer, an
     Agent's Message or a completed and signed Letter of Transmittal
     (or facsimile thereof), with any required signature guarantees,
     and in either case any other documents required by the Letter of
     Transmittal, must be delivered to the Exchange Agent by mail,
     facsimile, hand delivery or overnight courier at one of the
     Exchange Agent's addresses set forth under " Exchange Agent" on
     or prior to the Expiration Date and either (i) such Original
     Capital Securities must be tendered pursuant to the procedures
     for book-entry transfer set forth below or (ii) the guaranteed
     delivery procedures set forth below must be complied with.

          Except as set forth below, in order for Original Capital
     Securities to be validly tendered by a means other than by
     book-entry transfer, a completed and signed Letter of Transmittal
     (or facsimile thereof), with any required signature guarantees,
     and any other documents required by the Letter of Transmittal
     must be delivered to the Exchange Agent by mail, facsimile, hand
     delivery or overnight courier at one of the Exchange Agent's
     addresses set forth under " Exchange Agent" on or prior to the
     Expiration Date and either (i) such Original Capital Securities
     must be delivered to the Exchange Agent on or prior to the
     Expiration Date or (ii) the guaranteed delivery procedures set
     forth below must be complied with.  If less than all Original
     Capital Securities are tendered, a tendering holder should fill
     in the amount of Original Capital Securities being tendered in
     the appropriate box on the Letter of Transmittal.  The entire
     amount of Original Capital Securities delivered to the Exchange
     Agent will be deemed to have been tendered unless otherwise
     indicated.

          THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF
     TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND
     SOLE RISK OF THE TENDERING HOLDER, AND DELIVERY WILL BE DEEMED
     MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT.  IF
     DELIVERY IS TO BE BY MAIL, THE USE OF REGISTERED MAIL, RETURN
     RECEIPT REQUESTED, PROPERLY INSURED, OR AN OVERNIGHT DELIVERY
     SERVICE IS RECOMMENDED.  IN ALL CASES, SUFFICIENT TIME SHOULD BE
     ALLOWED TO ENSURE TIMELY DELIVERY.

          BOOK-ENTRY TRANSFER

          The Exchange Agent and DTC have confirmed that any
     Participant (as defined in "Description of Exchange
     Securities Description of Exchange Capital Securities Depositary
     Procedures") in DTC's book-entry transfer facility system may
     utilize DTC's ATOP procedures to tender Original Capital
     Securities.  The Exchange Agent will establish an account with
     respect to the Original Capital Securities at DTC for purposes of
     the Exchange Offer within two business days after the date of
     this Prospectus.  Any Participant may make a book-entry delivery
     of the Original Capital Securities by causing DTC to transfer
     such Original Capital Securities into the Exchange Agent's
     account at DTC in accordance with DTC's ATOP procedures for
     transfer.  However, although delivery of Original Capital
     Securities may be effected through book-entry transfer into the
     Exchange Agent's account at DTC, an Agent's Message or a
     completed and signed Letter of Transmittal (or facsimile
     thereof), with any required signature guarantees and any other
     documents required by the Letter of Transmittal, must in any case
     be delivered to and received by the Exchange Agent at one of its
     addresses set forth under " Exchange Agent" on or prior to the
     Expiration Date, or the guaranteed delivery procedure set forth
     below must be complied with.

          DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S
     PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

          Signature Guarantees.  Certificates for the Original Capital
     Securities need not be endorsed and signature guarantees on the
     Letter of Transmittal are unnecessary unless (a) a certificate
     for the Original Capital Securities is registered in a name other
     than that of the person surrendering the certificate or (b) such
     holder completes the box entitled "Special Issuance Instructions"
     or "Special Delivery Instructions" in the Letter of Transmittal. 
     In the case of (a) or (b) above, such certificates for Original
     Capital Securities must be duly endorsed or accompanied by a
     properly executed bond power, with the endorsement or signature
     on the bond power and on the Letter of Transmittal guaranteed by
     a firm or other entity identified in Rule 17Ad-15 under the
     Exchange Act as an "eligible guarantor institution," including
     (as such terms are defined therein): (i) a bank; (ii) a broker,
     dealer, municipal securities broker or dealer or government
     securities broker or dealer; (iii) a credit union; (iv) a
     national securities exchange, registered securities association
     or clearing agency; or (v) a savings association that is a
     participant in a Securities Transfer Association (an "Eligible
     Institution"), unless surrendered on behalf of such Eligible
     Institution.  See Instruction 1 to the Letter of Transmittal.

          Guaranteed Delivery.  If a holder desires to tender Original
     Capital Securities pursuant to the Exchange Offer and the
     certificates for such Original Capital Securities are not
     immediately available or time will not permit all required
     documents to reach the Exchange Agent on or prior to the
     Expiration Date, or the procedure for book-entry transfer cannot
     be completed on a timely basis, such Original Capital Securities
     may nevertheless be tendered, provided that all of the following
     guaranteed delivery procedures are complied with:

               (a)  such tenders are made by or through an Eligible
     Institution;

               (b)  properly completed and duly executed Notice of
          Guaranteed Delivery, substantially in the form accompanying
          the Letter of Transmittal, is received by the Exchange
          Agent, as provided below, on or prior to the Expiration
          Date; and

               (c)  the certificates (or a book-entry confirmation)
          representing all tendered Original Capital Securities, in
          proper form for transfer, together with a properly completed
          and duly executed Letter of Transmittal (or facsimile
          thereof), with any required signature guarantees and any
          other documents required by the Letter of Transmittal, are
          received by the Exchange Agent within three New York Stock
          Exchange, Inc. trading days after the date of execution of
          such Notice of Guaranteed Delivery.

          The Notice of Guaranteed Delivery may be delivered by hand,
     or transmitted by facsimile or mail to the Exchange Agent and
     must include a guarantee by an Eligible Institution in the form
     set forth in such notice.

          Notwithstanding any other provision hereof, the delivery of
     Exchange Capital Securities in exchange for Original Capital
     Securities tendered and accepted for exchange pursuant to the
     Exchange Offer will in all cases be made only after timely
     receipt by the Exchange Agent of Original Capital Securities, or
     of a book-entry confirmation with respect to such Original
     Capital Securities, and a properly completed and duly executed
     Letter of Transmittal (or facsimile thereof), together with any
     required signature guarantees and any other documents required by
     the Letter of Transmittal.  Accordingly, the delivery of Exchange
     Capital Securities might not be made to all tendering holders at
     the same time, and will depend upon when Original Capital
     Securities, book-entry confirmations with respect to Original
     Capital Securities and other required documents are received by
     the Exchange Agent.

          The Issuer Trust's acceptance for exchange of Original
     Capital Securities tendered pursuant to any of the procedures
     described above will constitute a binding agreement between the
     tendering holder and the Issuer Trust upon the terms and subject
     to the conditions of the Exchange Offer.

          Determination of Validity. All questions as to the form of
     documents, validity, eligibility (including time of receipt) and
     acceptance for exchange of any tendered Original Capital Securities
     will be determined by the Company and the Issuer Trust, in their
     sole discretion, whose determination shall be final and binding on
     all parties. The Company and the Issuer Trust reserve the absolute
     right, in their sole and absolute discretion, to reject any and all
     tenders determined by them not to be in proper form or the
     acceptance of which, or exchange for, may, in the opinion of
     counsel to the Company and the Issuer Trust, be unlawful. The
     Company and the Issuer Trust also reserve the absolute right,
     subject to applicable law, to waive any of the conditions of the
     Exchange Offer as set forth under " Conditions to the Exchange
     Offer" or any condition or irregularity in any tender of Original
     Capital Securities of any particular holder whether or not similar
     conditions or irregularities are waived in the case of other
     holders.

          The interpretation by the Company and the Issuer Trust of the
     terms and conditions of the Exchange Offer (including the Letter of
     Transmittal and the instructions thereto) will be final and
     binding. No tender of Original Capital Securities will be deemed to
     have been validly made until all irregularities with respect to
     such tender have been cured or waived. Neither the Company, the
     Issuer Trust, any affiliates or assigns of the Company or the
     Issuer Trust, the Exchange Agent nor any other person shall be
     under any duty to give any notification of any irregularities in
     tenders or incur any liability for failure to give any such
     notification.

          If any Letter of Transmittal, endorsement, bond power, power
     of attorney, or any other document required by the Letter of
     Transmittal is signed by a trustee, executor, administrator,
     guardian, attorney-in-fact, officer of a Corporation or other
     person acting in a fiduciary or representative capacity, such
     person should so indicate when signing, and unless waived by the
     Company and the Issuer Trust, proper evidence satisfactory to the
     Company and the Issuer Trust, in their sole discretion, of such
     person's authority to so act must be submitted.

          A beneficial owner of Original Capital Securities that are
     held by or registered in the name of a broker, dealer, commercial
     bank, trust Company or other nominee or custodian is urged to
     contact such entity promptly if such beneficial holder wishes to
     participate in the Exchange Offer.

     RESALES OF EXCHANGE CAPITAL SECURITIES

          The Issuer Trust is making the Exchange Offer for the Exchange
     Capital Securities in reliance on the position of the staff of the
     Division of Corporation Finance of the Commission as set forth in
     certain interpretive letters addressed to third parties in other
     transactions. However, neither the Company nor the Issuer Trust
     sought its own interpretive letter and there can be no assurance
     that the staff of the Division of Corporation Finance of the
     Commission would make a similar determination with respect to the
     Exchange Offer as it has in such interpretive letters to third
     parties. Based on these interpretations by the staff of the
     Division of Corporation Finance of the Commission, and subject to
     the two immediately following sentences, the Company and the Issuer
     Trust believe that Exchange Capital Securities issued pursuant to
     this Exchange Offer in exchange for Original Capital Securities may
     be offered for resale, resold and otherwise transferred by a holder
     thereof (other than a holder who is a broker-dealer) without
     further compliance with the registration and prospectus delivery
     requirements of the Securities Act, provided that such Exchange
     Capital Securities are acquired in the ordinary course of such
     holder's business and that such holder is not participating, and
     has no arrangement or understanding with any person to participate,
     in a distribution (within the meaning of the Securities Act) of
     such Exchange Capital Securities. However, any holder of Original
     Capital Securities who is an "affiliate" of the Company or the
     Issuer Trust or who intends to participate in the Exchange Offer
     for the purpose of distributing Exchange Capital Securities, or any
     broker-dealer who purchased Original Capital Securities from the
     Issuer Trust to resell pursuant to Rule 144A or any other available
     exemption under the Securities Act, (a) will not be able to rely on
     the interpretations of the staff of the Division of Corporation
     Finance of the Commission set forth in the above-mentioned
     interpretive letters, (b) will not be permitted or entitled to
     tender such Original Capital Securities in the Exchange Offer and
     (c) must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with any sale or
     other transfer of such Original Capital Securities unless such sale
     is made pursuant to an exemption from such requirements. In
     addition, as described below, if any broker-dealer holds Original
     Capital Securities acquired for its own account as a result of
     market-making or other trading activities and exchanges such
     Original Capital Securities for Exchange Capital Securities, then
     such broker-dealer must deliver a prospectus meeting the
     requirements of the Securities Act in connection with any resales
     of such Exchange Capital Securities.

          Each holder of Original Capital Securities who wishes to
     exchange Original Capital Securities for Exchange Capital
     Securities in the Exchange Offer will be required to represent that
     (i) it is not an "affiliate" of the Company or the Issuer Trust,
     (ii) any Exchange Capital Securities to be received by it are being
     acquired in the ordinary course of its business, (iii) it has no
     arrangement or understanding with any person to participate in a
     distribution (within the meaning of the Securities Act) of such
     Exchange Capital Securities, and (iv) if such holder is not a
     broker-dealer, such holder is not engaged in, and does not intend
     to engage in, a distribution (within the meaning of the Securities
     Act) of such Exchange Capital Securities. In addition, the Company
     and the Issuer Trust may require such holder, as a condition to
     such holder's eligibility to participate in the Exchange Offer, to
     furnish to the Company and the Issuer Trust (or an agent thereof)
     in writing information as to the number of "beneficial owners"
     (within the meaning of Rule 13d-3 under the Exchange Act) on behalf
     of whom such holder holds the Capital Securities to be exchanged in
     the Exchange Offer. Each broker-dealer that receives Exchange
     Capital Securities for its own account pursuant to the Exchange
     Offer must acknowledge that it acquired the Original Capital
     Securities for its own account as the result of market-making
     activities or other trading activities and must agree that it will
     deliver a prospectus meeting the requirements of the Securities Act
     in connection with any resale of such Exchange Capital Securities.
     The Letter of Transmittal states that by so acknowledging and by
     delivering a prospectus, a broker-dealer will not be deemed to
     admit that it is an "underwriter" within the meaning of the
     Securities Act. Based on the position taken by the staff of the
     Division of Corporation Finance of the Commission in the
     interpretive letters referred to above, the Company and the Issuer
     Trust believe that Participating Broker-Dealers who acquired
     Original Capital Securities for their own accounts as a result of
     market-making activities or other trading activities may fulfill
     their prospectus delivery requirements with respect to the Exchange
     Capital Securities received upon exchange of such Original Capital
     Securities (other than Original Capital Securities which represent
     an unsold allotment from the initial sale of the Original Capital
     Securities) with a prospectus meeting the requirements of the
     Securities Act, which may be the prospectus prepared for an
     exchange offer so long as it contains a description of the plan of
     distribution with respect to the resale of such Exchange Capital
     Securities. Accordingly, this Prospectus, as it may be amended or
     supplemented from time to time, may be used by a Participating
     Broker-Dealer during the period referred to below in connection
     with resales of Exchange Capital Securities received in exchange
     for Original Capital Securities where such Original Capital
     Securities were acquired by such Participating Broker-Dealer for
     its own account as a result of market-making or other trading
     activities. Subject to certain provisions set forth in the
     Registration Rights Agreement, the Company and the Issuer Trust
     have agreed that this Prospectus, as it may be amended or
     supplemented from time to time, may be used by a Participating
     Broker-Dealer in connection with resales of such Exchange Capital
     Securities for a period ending 180 days after the Expiration Date
     (subject to extension under certain limited circumstances described
     below) or, if earlier, when all such Exchange Capital Securities
     have been disposed of by such Participating Broker-Dealer. See
     "Plan of Distribution." However, a Participating Broker-Dealer who
     intends to use this Prospectus in connection with the resale of
     Exchange Capital Securities received in exchange for Original
     Capital Securities pursuant to the Exchange Offer must notify the
     Company or the Issuer Trust, or cause the Company or the Issuer
     Trust to be notified, on or prior to the Expiration Date, that it
     is a Participating Broker-Dealer. Such notice may be given in the
     space provided for that purpose in the Letter of Transmittal or may
     be delivered to the Exchange Agent at one of the addresses set
     forth herein under " Exchange Agent." Any Participating
     Broker-Dealer who is an "affiliate" of the Company or the Issuer
     Trust may not rely on such interpretive letters and must comply
     with the registration and prospectus delivery requirements of the
     Securities Act in connection with any resale transaction.

          In that regard, each Participating Broker-Dealer who
     surrenders Original Capital Securities pursuant to the Exchange
     Offer will be deemed to have agreed, by execution of the Letter of
     Transmittal, that upon receipt of notice from the Company or the
     Issuer Trust of the occurrence of any event or the discovery of (i)
     any fact which makes any statement contained or incorporated by
     reference in this Prospectus untrue in any material respect or (ii)
     any fact which causes this Prospectus to omit to state a material
     fact necessary in order to make the statements contained or
     incorporated by reference herein, in light of the circumstances
     under which they were made, not misleading, or (iii) of the
     occurrence of certain other events specified in the Registration
     Rights Agreement, such Participating Broker-Dealer will suspend the
     sale of Exchange Capital Securities (or the Exchange Guarantee or
     the Exchange Junior Subordinated Debentures, as applicable)
     pursuant to this Prospectus until the Company or the Issuer Trust
     has amended or supplemented this Prospectus to correct such
     misstatement or omission and has furnished copies of the amended or
     supplemented Prospectus to such Participating Broker-Dealer, or the
     Company or the Issuer Trust has given notice that the sale of the
     Exchange Capital Securities (or the Exchange Guarantee or the
     Exchange Junior Subordinated Debentures, as applicable) may be
     resumed, as the case may be. If the Company or the Issuer Trust
     gives such notice to suspend the sale of the Exchange Capital
     Securities (or the Exchange Guarantee or the Exchange Junior
     Subordinated Debentures, as applicable), it shall extend the
     180-day period referred to above during which Participating
     Broker-Dealers are entitled to use this Prospectus in connection
     with the resale of Exchange Capital Securities by the number of
     days during the period from and including the date of the giving of
     such notice to and including the date when Participating
     Broker-Dealers shall have received copies of the amended or
     supplemented Prospectus necessary to permit resales of the Exchange
     Capital Securities or to and including the date on which the
     Company or the Issuer Trust has given notice that the sale of
     Exchange Capital Securities (or the Exchange Guarantee or the
     Exchange Junior Subordinated Debentures, as applicable) may be
     resumed, as the case may be.

     WITHDRAWAL RIGHTS

          Except as otherwise provided herein, tenders of Original
     Capital Securities may be withdrawn at any time on or prior to the
     Expiration Date. In order for a withdrawal to be effective a
     written, telegraphic, telex or facsimile transmission of such
     notice of withdrawal must be timely received by the Exchange Agent
     at one of its addresses set forth under " Exchange Agent" on or
     prior to the Expiration Date. Any such notice of withdrawal must
     specify the name of the person who tendered the Original Capital
     Securities to be withdrawn, the aggregate principal amount of
     Original Capital Securities to be withdrawn, and (if certificates
     for such Original Capital Securities have been tendered) the name
     of the registered holder of the Original Capital Securities as set
     forth on the Original Capital Securities, if different from that of
     the person who tendered such Original Capital Securities. If
     Original Capital Securities have been delivered or otherwise
     identified to the Exchange Agent, then prior to the physical
     release of such Original Capital Securities, the tendering holder
     must submit the serial numbers shown on the particular Original
     Capital Securities to be withdrawn and the signature on the notice
     of withdrawal must be guaranteed by an Eligible Institution, except
     in the case of Original Capital Securities tendered for the account
     of an Eligible Institution. If Original Capital Securities have
     been tendered pursuant to the procedures for book-entry transfer
     set forth in " Procedures for Tendering Original Capital
     Securities," the notice of withdrawal must specify the name and
     number of the account at DTC to be credited with the withdrawal of
     Original Capital Securities, in which case a notice of withdrawal
     will be effective if delivered to the Exchange Agent by written,
     telegraphic, telex or facsimile transmission. Withdrawals of
     tenders of Original Capital Securities may not be rescinded.
     Original Capital Securities properly withdrawn will not be deemed
     validly tendered for purposes of the Exchange Offer, but may be
     retendered at any subsequent time on or prior to the Expiration
     Date by following any of the procedures described above under "
     Procedures for Tendering Original Capital Securities."

          All questions as to the validity, form and eligibility
     (including time of receipt) of such withdrawal notices will be
     determined by the Issuer Trust, in its sole discretion, whose
     determination shall be final and binding on all parties. Neither
     the Company, the Issuer Trust, any affiliates or assigns of the
     Company or the Issuer Trust, the Exchange Agent nor any other
     person shall be under any duty to give any notification of any
     irregularities in any notice of withdrawal or incur any liability
     for failure to give any such notification. Any Original Capital
     Securities which have been tendered but which are withdrawn will be
     returned to the holder thereof promptly after withdrawal.

     DISTRIBUTIONS ON EXCHANGE CAPITAL SECURITIES

          Holders of Original Capital Securities whose Original Capital
     Securities are accepted for exchange will not receive Distributions
     on such Original Capital Securities and will be deemed to have
     waived the right to receive any Distributions on such Original
     Capital Securities accumulated from and after October 15, 1997.
     Accordingly, holders of Exchange Capital Securities as of the
     record date for the payment of Distributions on January 15, 1998
     will be entitled to receive Distributions accumulated from and
     after October 15, 1997.

     CONDITIONS TO THE EXCHANGE OFFER

          Notwithstanding any other provisions of the Exchange Offer, or
     any extension of the Exchange Offer, the Company and the Issuer
     Trust will not be required to accept for exchange, or to exchange,
     any Original Capital Securities for any Exchange Capital
     Securities, and, as described below, may terminate the Exchange
     Offer (whether or not any Original Capital Securities have
     theretofore been accepted for exchange) or may waive any conditions
     to or amend the Exchange Offer, if any of the following conditions
     have occurred or exists or have not been satisfied:

          (a) there shall occur a change in the current interpretation
     by the staff of the Commission which permits the Exchange Capital
     Securities issued pursuant to the Exchange Offer in exchange for
     Original Capital Securities to be offered for resale, resold and
     otherwise transferred by holders thereof (other than broker-dealers
     and any such holder which is an "affiliate" of the Company or the
     Issuer Trust within the meaning of Rule 405 under the Securities
     Act) without compliance with the registration and prospectus
     delivery provisions of the Securities Act, provided that such
     Exchange Capital Securities are acquired in the ordinary course of
     such holders' business and such holders have no arrangement or
     understanding with any person to participate in the distribution of
     such Exchange Capital Securities; or

          (b) any law, statute, rule or regulation shall have been
     adopted or enacted which, in the judgment of the Company or the
     Issuer Trust, would reasonably be expected to impair its ability to
     proceed with the Exchange Offer; or

          (c) a stop order shall have been issued by the Commission or
     any state securities authority suspending the effectiveness of the
     Registration Statement, or proceedings shall have been initiated
     or, to the knowledge of the Company or the Issuer Trust, threatened
     for that purpose, or any governmental approval has not been
     obtained, which approval the Company or the Issuer Trust shall, in
     its sole discretion, deem necessary for the consummation of the
     Exchange Offer as contemplated hereby; or

          (d) the Company shall receive an opinion of counsel
     experienced in such matters to the effect that there is more than
     an insubstantial risk that consummation of the Exchange Offer would
     result in interest payable to the Issuer Trust on the Junior
     Subordinated Debentures being not deductible by the Company for
     United States federal income tax purposes.

          If the Company or the Issuer Trust determines in its sole and
     absolute discretion that any of the foregoing events or conditions
     has occurred or exists or has not been satisfied, it may, subject
     to applicable law, terminate the Exchange Offer (whether or not any
     Original Capital Securities have theretofore been accepted for
     exchange) or may waive any such condition or otherwise amend the
     terms of the Exchange Offer in any respect. If such waiver or
     amendment constitutes a material change to the Exchange Offer, the
     Company or the Issuer Trust will promptly disclose such waiver or
     amendment by means of a prospectus supplement that will be
     distributed to the registered holders of the Original Capital
     Securities and will extend the Exchange Offer to the extent
     required by Rule 14e-1 under the Exchange Act.

          Delivery to other than the above addresses or facsimile number
     will not constitute a valid delivery.

     FEES AND EXPENSES

          The Company has agreed to pay the Exchange Agent reasonable
     and customary fees for its services and will reimburse it for its
     reasonable out-of-pocket expenses in connection therewith. The
     Company will also pay brokerage houses and other custodians,
     nominees and fiduciaries the reasonable out-of-pocket expenses
     incurred by them in forwarding copies of this Prospectus and
     related documents to the beneficial owners of Original Capital
     Securities, and in handling or tendering for their customers.

          Holders who tender their Original Capital Securities for
     exchange will not be obligated to pay any transfer taxes in
     connection therewith. If, however, Exchange Capital Securities are
     to be delivered to, or are to be issued in the name of, any person
     other than the registered holder of the Original Capital Securities
     tendered, or if a transfer tax is imposed for any reason other than
     the exchange of Original Capital Securities in connection with the
     Exchange Offer, then the amount of any such transfer taxes (whether
     imposed on the registered holder or any other persons) will be
     payable by the tendering holder. If satisfactory evidence of
     payment of such taxes or exemption therefrom is not submitted with
     the Letter of Transmittal, the amount of such transfer taxes will
     be billed directly to such tendering holder.

          Neither the Company nor the Issuer Trust will make any payment
     to brokers, dealers or other nominees soliciting acceptances of the
     Exchange Offer.


                   DESCRIPTION OF EXCHANGE SECURITIES

          The terms of the Original Securities are identical in all
     materials respects to the Exchange Securities, except that (i) the
     Original Securities have not been registered under the Securities
     Act, are subject to certain restrictions on transfer and are
     entitled to certain rights under the applicable Registration Rights
     Agreement (which rights will terminate upon consummation of the
     Exchange Offer, except under limited circumstances), (ii) the
     Exchange Capital Securities will not contain the restrictions on
     transfer applicable to Original Capital Securities, (iii) the
     Exchange Capital Securities will not provide for any increase in
     the Distribution rate thereon and (iv) the Exchange Junior
     Subordinated Debentures will not provide for any increase in the
     interest rate thereon. The Original Securities provide that, in the
     event that a registration statement relating to the Exchange Offer
     has not been filed by October 13, 1997 and been declared effective
     by December 12, 1997, or, in certain limited circumstances, in the
     event a shelf registration statement (the "Shelf Registration
     Statement") with respect to the resale of the Original Capital
     Securities is not declared effective by the time required by the
     Registration Rights Agreement, then liquidated damages will accrue
     at the rate of 0.25% per annum on the principal amount of the
     Original Junior Subordinated Debentures and Distributions will
     accrue at the rate of 0.25% per annum on the Liquidation Amount of
     the Original Capital Securities, for the period from the occurrence
     of such event until such time as such registration statement has
     been filed or declared effective, as the case may be. The Exchange
     Securities are not, and upon consummation of the Exchange Offer the
     Original Securities will not be, entitled to any such additional
     interest or Distributions. Accordingly, holders of Original Capital
     Securities should review the information set forth under "Risk
     Factors Consequences of a Failure to Exchange Original Capital
     Securities" and "Description of Exchange Securities."

     DESCRIPTION OF EXCHANGE CAPITAL SECURITIES

          The Exchange Capital Securities will represent preferred
     beneficial interests in the Issuer Trust and the holders thereof
     will be entitled to a preference over the Common Securities in
     certain circumstances with respect to Distributions and amounts
     payable on redemption of the Trust Securities or liquidation of the
     Issuer Trust. See " Subordination of Common Securities." The Trust
     Agreement has been qualified under the Trust Indenture Act of 1939,
     as amended (the "Trust Indenture Act"). This summary of certain
     provisions of the Exchange Capital Securities, the Common
     Securities and the Trust Agreement does not purport to be complete
     and is subject to, and is qualified in its entirety by reference
     to, all the provisions of the Trust Agreement, including the
     definitions therein of certain terms.

          Whenever particular defined terms of the Trust Agreement (as
     amended or supplemented from time to time) are referred to herein,
     such defined terms are incorporated herein by reference. The Trust
     Agreement is available upon request from the Issuer Trustees.

          General. The Exchange Capital Securities will be limited to
     $110,000,000 aggregate Liquidation Amount outstanding. The Exchange
     Capital Securities will rank pari passu, and payments will be made
     thereon pro rata, with the Common Securities except as described
     under " Subordination of Common Securities." Legal title to the
     Junior Subordinated Debentures will be held by the Issuer Trust in
     trust for the benefit of the holders of the Trust Securities. The
     Exchange Guarantee Agreement executed by the Company for the
     benefit of the holders of the Exchange Capital Securities will be a
     guarantee on a subordinated basis with respect to the Exchange
     Capital Securities but will not guarantee payment of Distributions
     or amounts payable on redemption or liquidation of such Capital
     Securities when the Issuer Trust does not have funds on hand
     available to make such payments. See "Description of Exchange
     Guarantee."

          Distributions. The Exchange Capital Securities represent
     undivided beneficial interests in the assets of the Issuer Trust,
     and Distributions on each Exchange Capital Security will be payable
     at a variable annual rate equal to LIBOR plus .91% on the stated
     Liquidation Amount of $1,000, payable quarterly in arrears on
     January 15, April 15, July 15, and October 15 of each year (each a
     "Distribution Date"), to the holders of the Exchange Capital
     Securities at the close of business on the January 1, April 1, July
     1, and October 1, as the case may be, next preceding the relevant
     Distribution Date. Distributions on the Exchange Capital Securities
     will be cumulative. Distributions will accumulate from the date of
     original issuance. The amount of Distributions payable for any
     period will be computed on the basis of the actual number of days
     in the applicable Distribution period (which actual number of days
     shall include the first day but exclude the last day of such
     Distribution period) divided by 360. In the event that any date on
     which Distributions are payable on the Exchange Capital Securities
     is not a Business Day (as defined below), then payment of the
     Distributions payable on such date will be made on the next
     succeeding day that is a Business Day (and without any additional
     Distributions or other payment in respect of any such delay),
     except if such Business Day is in the next calendar year, such
     payment shall be made on the immediately preceding Business Day, in
     each case with the same force and effect as if made on the date
     such payment was originally payable.

          So long as no Event of Default under the Junior Subordinated
     Indenture has occurred and is continuing, the Company has the right
     under the Junior Subordinated Indenture to defer the payment of
     interest on the Exchange Junior Subordinated Debentures at any time
     or from time to time for a period not exceeding 20 consecutive
     quarterly periods with respect to each Extension Period, provided
     that no Extension Period may extend beyond the Stated Maturity of
     the Exchange Junior Subordinated Debentures. As a consequence of
     any such election, quarterly Distributions on the Exchange Capital
     Securities will be deferred by the Issuer Trust during any such
     Extension Period. Distributions to which holders of the Exchange
     Capital Securities are entitled will accumulate additional
     Distributions thereon at the rate per annum equal to LIBOR plus
     .91% on the stated Liquidation Amount of $1,000 thereof, compounded
     quarterly from the relevant payment date for such Distributions.
     The term "Distributions" as used herein shall include any such
     additional Distributions. During any such Extension Period, the
     Company may not, and may not permit any subsidiary of the Company
     to (i) declare or pay any dividends or distributions on, or redeem,
     purchase, acquire, or make a liquidation payment with respect to,
     any of the Company's capital stock, (ii) make any payment of
     principal, interest or premium, if any, on or repay, repurchase or
     redeem any debt securities of the Company that rank pari passu in
     all respects with or junior in interest to the Exchange Junior
     Subordinated Debentures or (iii) make any guarantee payments with
     respect to any guarantee by the Company of the debt securities of
     any subsidiary of the Company if such guarantee ranks pari passu
     with or junior in interest to the Exchange Junior Subordinated
     Debentures (other than (a) dividends or distributions in common
     stock of the Company, (b) any declaration of a dividend in
     connection with the implementation of a stockholders' rights plan,
     or the issuance of stock under any such plan in the future, or the
     redemption or repurchase of any such rights pursuant thereto, (c)
     payments under the Guarantee and (d) purchases of common stock
     related to the issuance of common stock or rights under any of the
     Company's or its subsidiaries' benefit plans for their directors,
     officers or employees). Prior to the termination of any such
     Extension Period, the Company may further defer the payment of
     interest, provided that no Extension Period may exceed 20
     consecutive quarterly periods or extend beyond the Stated Maturity
     of the Exchange Junior Subordinated Debentures. Upon the
     termination of any such Extension Period and the payment of all
     amounts then due, the Company may elect to begin a new Extension
     Period. There is no limitation on the number of times that the
     Company may elect to begin an Extension Period. See "Description of
     Exchange Junior Subordinated Debentures Option To Extend Interest
     Payment Period" and "Certain Federal Income Tax Consequences
     Interest Income and Original Issue Discount."

          The Company has no current intention of exercising its right
     to defer payments of interest by extending the interest payment
     period on the Exchange Junior Subordinated Debentures.

          The revenue of the Issuer Trust available for distribution to
     holders of the Exchange Capital Securities will be limited to
     payments under the Exchange Junior Subordinated Debentures in which
     the Issuer Trust will invest the proceeds from the issuance and
     sale of the Capital Securities. See "Description of Exchange Junior
     Subordinated Debentures." If the Company does not make interest
     payments on the Junior Subordinated Debentures, the Issuer Trust
     will not have funds available to pay Distributions on the Capital
     Securities. The payment of Distributions (if and to the extent the
     Issuer Trust has funds legally available or the payment of such
     Distributions and cash sufficient to make such payments) is
     guaranteed by the Company on a limited basis as set forth herein
     under "Description of Exchange Guarantee."

          Distribution Rate. LIBOR and the amount of Distributions
     payable in respect of each Distribution period will be calculated
     by First Chicago as Calculation Agent, in the same manner as LIBOR
     and the interest payable in respect of each interest payment period
     for the Exchange Junior Subordinated Debentures, as described under
     "Description of Exchange Junior Subordinated Debentures
     Determination of Interest Rate."

          Redemption. Upon the repayment or redemption, in whole or in
     part, of the Junior Subordinated Debentures, whether at maturity or
     upon earlier redemption as provided in the Junior Subordinated
     Indenture, the proceeds from such repayment or redemption shall be
     applied by the Property Trustee to redeem a Like Amount (as defined
     below) of the Trust Securities, upon not less than 30 nor more than
     60 days' notice, at a redemption price (the "Redemption Price")
     equal to the aggregate Liquidation Amount of such Trust Securities
     plus accumulated but unpaid Distributions thereon to the date of
     redemption (the "Redemption Date"). See "Description of Exchange
     Junior Subordinated Debentures Redemption." If less than all of the
     Junior Subordinated Debentures are to be repaid or redeemed on a
     Redemption Date, then the proceeds from such repayment or
     redemption shall be allocated to the redemption pro rata of the
     Capital Securities and the Common Securities. The amount of
     premium, if any, paid by the Company upon the redemption of all or
     any part of Junior Subordinated Debentures to be repaid or redeemed
     on a Redemption Date shall be allocated to the redemption pro rata
     of the Capital Securities and the Common Securities.

          The Company has the right to redeem the Junior Subordinated
     Debentures (i) on or after July 15, 2007, in whole at any time or
     in part from time to time, or (ii) in whole (but not in part) prior
     to July 15, 2007 and within 90 days following the occurrence of a
     Tax Event. A redemption of the Junior Subordinated Debentures would
     cause a mandatory redemption of the Capital Securities and Common
     Securities.

          "Business Day" means a day other than (i) a Saturday or a
     Sunday, (ii) a day on which banking institutions in The City of New
     York are authorized by law or executive order to remain closed, or
     (iii) a day on which the Property Trustee's corporate trust office
     or the corporate trust office of the Debenture Trustee is closed
     for business.

          "Like Amount" means (i) with respect to a redemption of
     Capital Securities, Capital Securities having a Liquidation Amount
     (as defined below) equal to that portion of the principal amount of
     Junior Subordinated Debentures to be contemporaneously redeemed in
     accordance with the Junior Subordinated Debentures, allocated to
     the Common Securities and to the Capital Securities based upon the
     relative Liquidation Amounts of such classes and the proceeds of
     which will be used to pay the Redemption Price of the Capital
     Securities and (ii) with respect to a distribution of Junior
     Subordinated Debentures to holders of Capital Securities in
     connection with a dissolution or liquidation of the Issuer Trust,
     Junior Subordinated Debentures having a principal amount equal to
     the Liquidation Amount of the Capital Securities of the holder to
     whom such Junior Subordinated Debentures are distributed.

          "Liquidation Amount" means the stated amount of $1,000 per
     Capital Security.

          Payment of Additional Sums. In the event a Tax Event has
     occurred and is continuing and the Issuer Trust is the holder of
     all of the Junior Subordinated Debentures, the Company will pay
     Additional Sums (as defined below), if any, on the Junior
     Subordinated Debentures.

          "Additional Sums" means the additional amounts as may be
     necessary in order that the amount of Distributions then due and
     payable by the Issuer Trust on the outstanding Capital Securities
     and Common Securities of the Issuer Trust shall not be reduced as a
     result of any additional taxes, duties and other governmental
     charges to which the Issuer Trust has become subject as a result of
     a Tax Event.

          Redemption Procedures. Exchange Capital Securities redeemed on
     each Redemption Date shall be redeemed at the Redemption Price with
     the applicable proceeds from the contemporaneous redemption of the
     Exchange Junior Subordinated Debentures. Redemptions of the
     Exchange Capital Securities shall be made and the Redemption Price
     shall be payable on each Redemption Date only to the extent that
     the Issuer Trust has funds on hand available for the payment of
     such Redemption Price. See also " Subordination of Common
     Securities."

          If the Issuer Trust gives a notice of redemption in respect of
     the Exchange Capital Securities, then, by 12:00 noon, New York City
     time, on the Redemption Date, to the extent funds are available, in
     the case of Exchange Capital Securities held in book-entry form,
     the Property Trustee will deposit irrevocably with DTC funds
     sufficient to pay the applicable Redemption Price and will give DTC
     irrevocable instructions and authority to pay the Redemption Price
     to the holders of the Exchange Capital Securities. With respect to
     Exchange Capital Securities not held in book-entry form, the
     Property Trustee, to the extent funds are available, will
     irrevocably deposit with the paying agent for the Exchange Capital
     Securities funds sufficient to pay the applicable Redemption Price
     and will give such paying agent irrevocable instructions and
     authority to pay the Redemption Price to the holders thereof upon
     surrender of their certificates evidencing the Exchange Capital
     Securities. Notwithstanding the foregoing, Distributions payable on
     or prior to the Redemption Date for any Exchange Capital Securities
     called for redemption shall be payable to the holders of the
     Exchange Capital Securities on the relevant record dates for the
     related Distribution Dates. If notice of redemption shall have been
     given and funds deposited as required, then upon the date of such
     deposit, all rights of the holders of such Exchange Capital
     Securities so called for redemption will cease, except the right of
     the holders of such Exchange Capital Securities to receive the
     Redemption Price, but without interest on such Redemption Price,
     and such Exchange Capital Securities will cease to be outstanding.
     In the event that any date fixed for redemption of Exchange Capital
     Securities is not a Business Day, then payment of the Redemption
     Price payable on such date will be made on the next succeeding day
     which is a Business Day (and without any interest or other payment
     in respect of any such delay), except that, if such Business Day
     falls in the next calendar year, such payment will be made on the
     immediately preceding Business Day. In the event that payment of
     the Redemption Price in respect of Exchange Capital Securities
     called for redemption is improperly withheld or refused and not
     paid either by the Issuer Trust or by the Company pursuant to the
     Exchange Guarantee as described under "Description of Exchange
     Guarantee," Distributions on such Exchange Capital Securities will
     continue to accrue at the then applicable rate, from the Redemption
     Date originally established by the Issuer Trust for such Exchange
     Capital Securities to the date such Redemption Price is actually
     paid, in which case the actual payment date will be the date fixed
     for redemption for purposes of calculating the Redemption Price.

          Subject to applicable law (including, without limitation,
     United States federal securities law), the Company or its
     subsidiaries may at any time and from time to time purchase
     outstanding Capital Securities by tender, in the open market or by
     private agreement.

          If less than all of the Capital Securities and Common
     Securities are to be redeemed on a Redemption Date, then the
     aggregate Liquidation Amount of such Capital Securities and Common
     Securities to be redeemed shall be allocated pro rata to the
     Capital Securities and the Common Securities based upon the
     relative Liquidation Amounts of such classes. The particular
     Capital Securities to be redeemed shall be selected on a pro rata
     basis not more than 60 days prior to the Redemption Date by the
     Property Trustee from the outstanding Capital Securities not
     previously called for redemption. The Property Trustee shall
     promptly notify the trust registrar in writing of the Capital
     Securities selected for redemption and, in the case of any Capital
     Securities selected for partial redemption, the Liquidation Amount
     thereof to be redeemed. For all purposes of the Trust Agreement,
     unless the context otherwise requires, all provisions relating to
     the redemption of Capital Securities shall relate, in the case of
     any Capital Securities redeemed or to be redeemed only in part, to
     the portion of the aggregate Liquidation Amount of Capital
     Securities which has been or is to be redeemed.

          Notice of any redemption will be mailed at least 30 days but
     not more than 60 days before the Redemption Date to each holder of
     Capital Securities to be redeemed at its registered address. Unless
     the Company defaults in payment of the Redemption Price on the
     Junior Subordinated Debentures, on and after the Redemption Date
     interest will cease to accrue on the Junior Subordinated Debentures
     or portions thereof (and distributions will cease to accumulate on
     the Capital Securities or portions thereof) called for redemption.

          Conditional Right to Shorten Maturity or Redeem upon a Tax
     Event. If a Tax Event occurs then the Company shall have the right,
     prior to the termination of the Issuer Trust, (i) to shorten the
     Stated Maturity of the Junior Subordinated Debentures to the
     minimum extent required, but in any event to a date not earlier
     than April 15, 2012 (the action referred to in this clause (i)
     being referred to herein as a "Maturity Advancement"), such that,
     in the opinion of counsel to the Company experienced in such
     matters, after advancing the Stated Maturity, interest paid on the
     Junior Subordinated Debentures will be deductible for federal
     income tax purposes, or (ii) to redeem the Junior Subordinated
     Debentures, in whole but not in part, at any time within 90 days
     following the occurrence of the Tax Event at a Redemption Price
     equal to 100% of the principal amount thereof plus accrued and
     unpaid interest thereon to the Redemption Date. See "Description of
     Exchange Capital Securities Redemption" and "Description of
     Exchange Junior Subordinated Debentures General" and " Redemption".

          Holders of Capital Securities should consult their own tax
     advisors regarding the tax consequences to them of a Maturity
     Advancement.

          See "Certain Federal Tax Law Considerations--Possible Tax Law
     Changes" and "Risk Factors--Tax Event Shortening of Maturity or
     Redemption" and "--Possible Tax Law Changes Affecting the Capital
     Securities" for a discussion of previous legislative proposals. The
     adoption of similar legislation could give rise to a Tax Event,
     which may permit the Company to shorten the Stated Maturity of the
     Junior Subordinated Debentures or cause a redemption of the Capital
     Securities prior to July 15, 2007.

          Subordination of Common Securities. Payment of Distributions
     on, and the Redemption Price of, the Issuer Trust's Capital
     Securities and Common Securities, as applicable, shall be made pro
     rata based on the Liquidation Amount of such Capital Securities and
     Common Securities; provided, however, that if on any Distribution
     Date or Redemption Date a Debenture Event of Default shall have
     occurred and be continuing, no payment of any Distribution on, or
     Redemption Price of, any of the Common Securities, and no other
     payment on account of the redemption, liquidation or other
     acquisition of such Common Securities, shall be made unless payment
     in full in cash of all accumulated and unpaid Distributions on all
     of the outstanding Capital Securities for all Distribution periods
     terminating on or prior thereto, or in the case of payment of the
     Redemption Price the full amount of such Redemption Price on all of
     the outstanding Capital Securities then called for redemption,
     shall have been made or provided for, and all funds available to
     the Property Trustee shall first be applied to the payment in full
     in cash of all Distributions on, or Redemption Price of, the
     Capital Securities then due and payable.

          In the case of any Event of Default resulting from a Debenture
     Event of Default, the Company as holder of the Common Securities
     will be deemed to have waived any right to act with respect to any
     such Event of Default under the Trust Agreement until the effect of
     all such Events of Default with respect to such Capital Securities
     have been cured, waived or otherwise eliminated. Until any such
     Events of Default under the Trust Agreement with respect to the
     Capital Securities have been so cured, waived or otherwise
     eliminated, the Property Trustee shall act solely on behalf of the
     holders of such Capital Securities and not on behalf of the Company
     as holder of the Common Securities, and only the holders of such
     Capital Securities will have the right to direct the Property
     Trustee to act on their behalf.

          Liquidation Distribution Upon Termination. The amount payable
     on the Capital Securities in the event of any liquidation of the
     Issuer Trust is $1,000 per Capital Security plus accumulated and
     unpaid Distributions, which may be in the form of a distribution of
     such amount in Junior Subordinated Debentures, subject to certain
     exceptions.

          The holders of all of the outstanding Common Securities have
     the right at any time to terminate the Issuer Trust and, after
     satisfaction of the liabilities of creditors of the Issuer Trust as
     provided by applicable law, cause the Junior Subordinated
     Debentures to be distributed to the holders of the Capital
     Securities and Common Securities in liquidation of the Issuer
     Trust, subject to (i) the Property Trustee having received an
     opinion of counsel to the effect that such distribution will not be
     a taxable event to holders of Capital Securities.

          Pursuant to the Trust Agreement, the Issuer Trust shall
     automatically terminate upon expiration of its term and shall
     terminate on the first to occur of: (i) certain events of
     bankruptcy, dissolution or liquidation of the Company; (ii) the
     distribution of a Like Amount of the Junior Subordinated Debentures
     to the holders of its Trust Securities, if the holders of Common
     Securities have given written direction to the Property Trustee to
     terminate the Issuer Trust (which direction, subject to the
     foregoing restrictions, is optional and wholly within the
     discretion of the holders of Common Securities); (iii) redemption
     of all of the Capital Securities as described under "Description of
     Exchange Capital Securities Redemption" or (iv) the entry of an
     order for the dissolution of the Issuer Trust by a court of
     competent jurisdiction.

          If an early termination occurs as described in clause (i),
     (ii) or (iv) above, the Issuer Trust shall be liquidated by the
     Issuer Trustees as expeditiously as the Issuer Trustees determine
     to be possible by distributing, after satisfaction of liabilities
     to creditors of the Issuer Trust as provided by applicable law, to
     the holders of such Trust Securities a Like Amount of the Junior
     Subordinated Debentures, unless such distribution is determined by
     the Property Trustee not to be practical, in which event such
     holders will be entitled to receive out of the assets of the Issuer
     Trust available for distribution to holders, after satisfaction of
     liabilities to creditors of the Issuer Trust as provided by
     applicable law, an amount equal to, in the case of holders of
     Capital Securities, the aggregate of the Liquidation Amount plus
     accumulated and unpaid Distributions thereon to the date of payment
     (such amount being the "Liquidation Distribution"). If such
     Liquidation Distribution can be paid only in part because the
     Issuer Trust has insufficient assets available to pay in full the
     aggregate Liquidation Distribution, then the amounts payable
     directly by the Issuer Trust on its Capital Securities shall be
     paid on a pro rata basis. The holder(s) of the Common Securities
     will be entitled to receive distributions upon any such liquidation
     pro rata with the holders of the Capital Securities, except that if
     a Debenture Event of Default has occurred and is continuing, the
     Capital Securities shall have a priority over the Common
     Securities.

          After the liquidation date fixed for any distribution of
     Junior Subordinated Debentures (i) the Capital Securities will no
     longer be deemed to be outstanding, (ii) DTC or its nominee, as the
     record holder of the Capital Securities, will receive a registered
     global certificate or certificates representing the Junior
     Subordinated Debentures to be delivered upon such distribution with
     respect to Capital Securities held by DTC or its nominee and (iii)
     any certificates representing the Capital Securities not held by
     DTC or its nominee will be deemed to represent the Junior
     Subordinated Debentures having a principal amount equal to the
     stated Liquidation Amount of the Capital Securities and bearing
     accrued and unpaid interest in an amount equal to the accumulated
     and unpaid Distributions on the Capital Securities until such
     certificates are presented to the Security Registrar for transfer
     or reissuance.

          If the Company does not redeem the Junior Subordinated
     Debentures prior to maturity and the Issuer Trust is not liquidated
     and the Junior Subordinated Debentures are not distributed to
     holders of the Capital Securities, the Capital Securities will
     remain outstanding until the repayment of the Junior Subordinated
     Debentures.

          There can be no assurance as to the market prices for the
     Capital Securities or the Junior Subordinated Debentures that may
     be distributed in exchange for Capital Securities if a dissolution
     and liquidation of the Issuer Trust were to occur. Accordingly, the
     Capital Securities that an investor may purchase, or the Junior
     Subordinated Debentures that the investor may receive on
     dissolution and liquidation of the Issuer Trust, may trade at a
     discount to the price that the investor paid to purchase the
     Capital Securities offered hereby.

          Events of Default; Notice. Any one of the following events
     constitutes an "Event of Default" under the Trust Agreement (an
     "Event of Default") with respect to the Capital Securities
     (whatever the reason for such Event of Default and whether it shall
     be voluntary or involuntary or be effected by operation of law or
     pursuant to any judgment, decree or order of any court or any
     order, rule or regulation of any administrative or governmental
     body):

          (i) the occurrence of a Debenture Event of Default under the
     Exchange Junior Subordinated Indenture (see "Description of
     Exchange Junior Subordinated Debentures Debenture Events of
     Default"); or

          (ii) default by the Issuer Trust in the payment of any
     Distribution when it becomes due and payable, and continuation of
     such default for a period of 30 days (subject to the deferral of
     any due date in the case of an Extension Period); or

          (iii) default by the Issuer Trust in the payment of any
     Redemption Price of any Trust Security when it becomes due and
     payable; or

          (iv) default in the performance, or breach, in any material
     respect, of any covenant or warranty of the Issuer Trustees in the
     Trust Agreement (other than a covenant or warranty a default in the
     performance of which or the breach of which is dealt with in clause
     (ii) or (iii) above), and continuation of such default or breach
     for a period of 90 days after there has been given, by registered
     or certified mail, to the Issuer Trustees by the holders of at
     least 25% in aggregate Liquidation Amount of the outstanding
     Capital Securities a written notice specifying such default or
     breach and requiring it to be remedied and stating that such notice
     is a "Notice of Default" under the Trust Agreement; or

          (v) the occurrence of certain events of bankruptcy or
     insolvency with respect to the Property Trustee if a successor
     Property Trustee has not been appointed within 90 days thereof.

          Within five Business Days after the occurrence of any Event of
     Default actually known to the Property Trustee, the Property
     Trustee shall transmit notice of such Event of Default to the
     holders of Trust Securities and the Administrators, unless such
     Event of Default shall have been cured or waived. The Company, as
     Depositor, and the Administrators are required to file annually
     with the Property Trustee a certificate as to whether or not they
     are in compliance with all the conditions and covenants applicable
     to them under the Trust Agreement.

          If a Debenture Event of Default has occurred and is
     continuing, the Capital Securities shall have a preference over the
     Common Securities upon termination of the Issuer Trust as described
     above. See " Liquidation Distribution Upon Termination." The
     existence of an Event of Default does not entitle the holders of
     Capital Securities to accelerate the maturity thereof.

          Removal of Issuer Trustees; Appointment of Successors. The
     holders of a majority in Liquidation Amount of Capital Securities
     may remove an Issuer Trustee for cause or, if an Event of Default
     has occurred and is continuing, with or without cause. Unless an
     Event of Default described in (i), (ii) or (iii) of the definition
     thereof or an event which with notice and/or lapse of time would
     constitute such an Event of Default (collectively, an "Issuer Trust
     Default") shall have occurred and be continuing, any Issuer Trustee
     may be removed at any time by the holder of the Common Securities.
     If an Issuer Trustee shall resign, be removed by the holder of
     Common Securities or the holder of Capital Securities, become
     incapable of acting as trustee, or if a vacancy shall occur in the
     office of any Issuer Trustee for any cause, (i) if an Issuer Trust
     Default has not occurred, or has occurred and is not continuing,
     the holder of the Common Securities, or (ii) if an Issuer Trust
     Default has occurred and is continuing, the applicable Issuer
     Trustee (unless a Debenture Event of Default has occurred and is
     continuing), or the holders of at least 25% in Liquidation Amount
     of Capital Securities, shall appoint a successor. If a successor
     has not been appointed, any holder of Capital Securities or Common
     Securities or the Property Trustee may petition a court in the
     State of Delaware to appoint a successor. Any Delaware Trustee must
     meet the applicable requirements of Delaware law. Any Property
     Trustee must be a national or state-chartered bank and at the time
     of appointment have capital and surplus of at least $50,000,000. No
     resignation or removal of an Issuer Trustee and no appointment of a
     successor trustee shall be effective until the acceptance of
     appointment by the successor trustee in accordance with the
     provisions of the Trust Agreement.

          Merger or Consolidation of Issuer Trustees. Any entity into
     which the Property Trustee or the Delaware Trustee may be merged or
     converted or with which it may be consolidated, or any entity
     resulting from any merger, conversion or consolidation to which
     such Trustee shall be a party, or any entity succeeding to all or
     substantially all the corporate trust business of such Trustee,
     shall be the successor of such Trustee under the Trust Agreement,
     provided such entity shall be otherwise qualified and eligible.

          Mergers, Consolidations, Amalgamations or Replacements of the
     Issuer Trust. The Issuer Trust may not merge with or into,
     consolidate, amalgamate, or be replaced by, or convey, transfer or
     lease its properties and assets substantially as an entirety, to
     any entity, except as described below or as otherwise set forth in
     the Trust Agreement. The Issuer Trust may, at the request of the
     holder of the Common Securities and with the consent of the
     Administrative Trustees, but without the consent of the holders of
     the outstanding Trust Securities, merge with or into, consolidate,
     amalgamate, or be replaced by or convey, transfer or lease its
     properties and assets substantially as an entirety to a trust
     organized as such under the laws of any State; provided, that (i)
     such successor entity either (a) expressly assumes all of the
     obligations of the Issuer Trust with respect to the Capital
     Securities or (b) substitutes for the Capital Securities other
     securities having substantially the same terms as the Capital
     Securities (the "Successor Securities") so long as the Successor
     Securities rank the same as the Capital Securities rank in priority
     with respect to distributions and payments upon liquidation,
     redemption and otherwise, (ii) a trustee of such successor entity
     is appointed possessing the same powers and duties as the Property
     Trustee as the holder of the Junior Subordinated Debentures, (iii)
     such merger, consolidation, amalgamation, replacement, conveyance,
     transfer or lease does not cause the Capital Securities (including
     any Successor Securities) to be downgraded by any nationally
     recognized statistical rating organization, (iv) such merger,
     consolidation, amalgamation, replacement, conveyance, transfer or
     lease does not adversely affect the rights, preferences and
     privileges of the holders of the Capital Securities (including any
     Successor Securities) in any material respect, (v) such successor
     entity has a purpose substantially identical to that of the Issuer
     Trust, (vi) prior to such merger, consolidation, amalgamation,
     replacement, conveyance, transfer or lease, the Issuer Trust has
     received an opinion from independent counsel experienced in such
     matters to the effect that (a) such merger, consolidation,
     amalgamation, replacement, conveyance, transfer or lease does not
     adversely affect the rights, preferences and privileges of the
     holders of the Capital Securities (including any Successor
     Securities) in any material respect and (b) following such merger,
     consolidation, amalgamation, replacement, conveyance, transfer or
     lease, neither the Issuer Trust nor such successor entity will be
     required to register as an investment Company under the Investment
     Company Act of 1940, as amended (the "Investment Company Act"), and
     (vii) the Company or any permitted successor or assignee owns all
     of the common securities of such successor entity and guarantees
     the obligations of such successor entity under the Successor
     Securities at least to the extent provided by the Guarantee.
     Notwithstanding the foregoing, the Issuer Trust shall not, except
     with the consent of each holder of Capital Securities, consolidate,
     amalgamate, merge with or into, or be replaced by or convey,
     transfer or lease its properties and assets substantially as an
     entirety to any other entity or permit any other entity to
     consolidate, amalgamate, merge with or into, or replace it if such
     consolidation, amalgamation, merger, replacement, conveyance,
     transfer or lease would cause the Issuer Trust or the successor
     entity to be classified as other than a grantor trust for United
     States federal income tax purposes.

          Voting Rights; Amendment of Trust Agreement. Except as
     provided below and under "Description of Exchange Guarantee--
     Amendments and Assignment" and as otherwise required by law and the
     Trust Agreement, the holders of the Capital Securities will have no
     voting rights.

          The Trust Agreement may be amended from time to time by the
     holders of a majority of the Common Securities and the Property
     Trustee, without the consent of the holders of the Capital
     Securities (i) to cure any ambiguity, correct or supplement any
     provisions in the Trust Agreement that may be inconsistent with any
     other provision, or to make any other provisions with respect to
     matters or questions arising under the Trust Agreement, which shall
     not be inconsistent with the other provisions of the Trust
     Agreement, or (ii) to modify, eliminate or add to any provisions of
     the Trust Agreement to such extent as shall be necessary to ensure
     that the Issuer Trust will be classified for United States federal
     income tax purposes as a grantor trust at all times that any Trust
     Securities are outstanding or to ensure that the Issuer Trust will
     not be required to register as an "investment company" under the
     Investment Company Act; provided, however, such action shall not
     adversely affect in any material respect the interests of any
     holder of Trust Securities, and any amendments of the Trust
     Agreement shall become effective when notice thereof is given to
     the holders of Trust Securities. The Trust Agreement may be amended
     by the holders of a majority of the Common Securities and the
     Property Trustee with (i) the consent of holders representing not
     less than a majority (based upon Liquidation Amounts) of the
     outstanding Capital Securities and (ii) receipt by the Issuer
     Trustees of an opinion of counsel to the effect that such amendment
     or the exercise of any power granted to the Issuer Trustees in
     accordance with such amendment will not affect the Issuer Trust's
     status as a grantor trust for United States federal income tax
     purposes or the Issuer Trust's exemption from status as an
     "investment company" under the Investment Company Act.
     Notwithstanding the foregoing, without the consent of each holder
     of Trust Securities, the Trust Agreement may not be amended to (i)
     change the amount or timing of any Distribution on the Trust
     Securities or otherwise adversely affect the amount of any
     Distribution required to be made in respect of the Trust Securities
     as of a specified date or (ii) restrict the right of a holder of
     Trust Securities to institute suit for the enforcement of any such
     payment on or after such date. The Exchange Capital Securities and
     any Original Capital Securities which remain outstanding after
     consummation of the Exchange Offer will vote together as a single
     class for purposes of determining whether holders of the requisite
     percentage in outstanding Liquidation Amount thereof have taken
     certain actions or exercised certain rights under the Trust
     Agreement.

          So long as any Junior Subordinated Debentures are held by the
     Issuer Trust, the Issuer Trustees shall not (i) direct the time,
     method and place of conducting any proceeding for any remedy
     available to the Debenture Trustee, or executing any trust or power
     conferred on the Property Trustee with respect to the Junior
     Subordinated Debentures, (ii) waive any past default that is
     waivable under Section 5.13 of the Junior Subordinated Indenture,
     (iii) exercise any right to rescind or annul a declaration that the
     principal of all the Junior Subordinated Debentures shall be due
     and payable or (iv) consent to any amendment, modification or
     termination of the Junior Subordinated Indenture or the Junior
     Subordinated Debentures, where such consent shall be required,
     without, in each case, obtaining the prior approval of the holders
     of a majority in aggregate Liquidation Amount of all outstanding
     Capital Securities; provided, however, that where a consent under
     the Junior Subordinated Indenture would require the consent of each
     holder of Junior Subordinated Debentures affected thereby, no such
     consent shall be given by the Property Trustee without the prior
     consent of each holder of the Capital Securities. The Issuer
     Trustees shall not revoke any action previously authorized or
     approved by a vote of the holders of the Capital Securities except
     by subsequent vote of the holders of the Capital Securities. The
     Property Trustee shall notify each holder of Capital Securities of
     any notice of default with respect to the Junior Subordinated
     Debentures. In addition to obtaining the foregoing approvals of the
     holders of the Capital Securities, prior to taking any of the
     foregoing actions, the Issuer Trustees shall obtain an opinion of
     counsel experienced in such matters to the effect that the Issuer
     Trust will not be classified as an association taxable as a
     corporation for United States federal income tax purposes on
     account of such action.

          Any required approval of holders of Exchange Capital
     Securities may be given at a meeting of holders of Exchange Capital
     Securities convened for such purpose or pursuant to written
     consent. The Property Trustee will cause a notice of any meeting at
     which holders of Exchange Capital Securities are entitled to vote,
     or of any matter upon which action by written consent of such
     holders is to be taken, to be given to each holder of record of
     Exchange Capital Securities in the manner set forth in the Trust
     Agreement.

          No vote or consent of the holders of Capital Securities will
     be required to redeem and cancel Capital Securities in accordance
     with the Trust Agreement.

          Notwithstanding that holders of Capital Securities are
     entitled to vote or consent under any of the circumstances
     described above, any of the Capital Securities that are owned by
     the Company, the Issuer Trustees or any affiliate of the Company or
     any Issuer Trustee shall, for purposes of such vote or consent, be
     treated as if they were not outstanding.

          Form, Denomination, Book-Entry Procedures and Transfer. The
     Exchange Capital Securities initially will be represented by one or
     more Capital Securities in registered, global form (collectively,
     the "Global Capital Securities"). The Global Capital Securities
     will be deposited upon issuance with the Property Trustee as
     custodian for DTC, in New York, New York, and registered in the
     name of DTC or its nominee, in each case for credit to an account
     of a direct or indirect participant in DTC as described below.

          Except as set forth below, the Global Capital Securities may
     be transferred, in whole and not in part, only to another nominee
     of DTC or to a successor of DTC or its nominee, and such transfer
     shall be effective only when reflected in the securities register
     maintained by or on behalf of the Issuer Trust. Beneficial
     interests in the Global Capital Securities may not be exchanged for
     Capital Securities in certificated form except in the limited
     circumstances described below. See " Exchange of Book-Entry Capital
     Securities for Certificated Capital Securities".

          Other Capital Securities will be issued only in registered,
     certificated (i.e., non-global) form. Other Capital Securities may
     not be exchanged for beneficial interests in any Global Capital
     Securities except in the limited circumstances described below. See
     " Exchange of Certificated Capital Securities for Book-Entry
     Capital Securities".

          Depositary Procedures. DTC has advised the Issuer Trust and
     the Company that DTC is a limited-purpose trust Company created to
     hold securities for its participating organizations (collectively.
     the "Participants") and to facilitate the clearance and settlement
     of transactions in those securities between Participants through
     electronic book-entry changes in accounts of its Participants. The
     Participants include securities brokers and dealers (including the
     Initial Purchasers), banks, trust companies, clearing Corporations
     and certain other organizations. Access to DTC's system is also
     available to other entities such as banks, brokers, and trust
     companies that clear through or maintain a custodial relationship
     with a Participant, either directly or indirectly (collectively,
     the "Indirect Participants"). Persons who are not Participants may
     beneficially own securities held by or on behalf of DTC only
     through the Participants or the Indirect Participants. The
     ownership and transfer of ownership interest of each actual
     purchaser of each security held by or on behalf of DTC are recorded
     on the records of the Participants and Indirect Participants.

          DTC has also advised the Issuer Trust and the Company that,
     pursuant to procedures established by it, (i) upon deposit of the
     Global Capital Securities, DTC will credit the accounts of
     Participants designated by the Initial Purchasers with portions of
     the Liquidation Amount of the Global Capital Securities and (ii)
     ownership of such interests in the Global Capital Securities will
     be shown on, and the transfer of ownership thereof will be effected
     only through, records maintained by DTC (with respect to the
     Participants) or by the Participants and the Indirect Participants
     (with respect to other owners of beneficial interests in the Global
     Capital Securities).

          Investors in the Global Capital Securities may hold their
     interests directly through DTC if they are participants in such
     system, or indirectly through organizations which are participants
     in such system. All interests in a Global Capital Security may be
     subject to the procedures and requirements of DTC. The laws of some
     states require that certain persons take physical delivery in
     certificated form of securities that they own. Consequently, the
     ability to transfer beneficial interests in a Global Capital
     Security to such persons will be limited to that extent. Because
     DTC can act only on behalf of Participants, which in turn act on
     behalf of Indirect Participants and certain banks, the ability of a
     person having beneficial interests in a Global Capital Security to
     pledge such interests to persons or entities that do not
     participate in the DTC system, or otherwise take actions in respect
     of such interests, may be affected by the lack of a physical
     certificate evidencing such interests. For certain other
     restrictions on the transferability of the Capital Securities, see
     " Exchange of Book-Entry Capital Securities for Certificated
     Capital Securities" and " Exchange of Certificated Capital
     Securities for Book-Entry Capital Securities".

          Except as described below, owners of interests in the Global
     Capital Securities will not have Capital Securities registered in
     their name, will not receive physical delivery of Capital
     Securities in certificated form and will not be considered the
     registered owners or holders thereof under the Issuer Trust
     Agreement for any purpose.

          Payments in respect of the Global Capital Security registered
     in the name of DTC or its nominee will be payable by the Property
     Trustee to DTC in its capacity as the registered holder under the
     Trust Agreement. Under the terms of the Trust Agreement, the
     Property Trustee will treat the persons in whose names the Capital
     Securities, including the Global Capital Securities, are registered
     as the owners thereof for the purpose of receiving such payments
     and for any and all other purposes whatsoever. Consequently,
     neither the Property Trustee nor any agent thereof has or will have
     any responsibility or liability for (i) any aspect of DTC's records
     or any Participant's or Indirect Participant's records relating to
     or payments made on account of beneficial ownership interests in
     the Global Capital Securities, or for maintaining, supervising or
     reviewing any of DTC's records or any Participant's or Indirect
     Participant's records relating to the beneficial ownership
     interests in the Global Capital Securities or (ii) any other matter
     relating to the actions and practices of DTC or any of its
     Participants or Indirect Participants. DTC has advised the Issuer
     Trust and the Company that its current practice, upon receipt of
     any payment in respect of securities such as the Capital
     Securities, is to credit the accounts of the relevant Participants
     with the payment on the payment date, in amounts proportionate to
     their respective holdings in Liquidation Amount of beneficial
     interests in the relevant security as shown on the records of DTC
     unless DTC has reason to believe it will not receive payment on
     such payment date. Payments by the Participants and the Indirect
     Participants to the beneficial owners of Capital Securities will be
     governed by standing instructions and customary practices and will
     be the responsibility of the Participants or the Indirect
     Participants and will not be the responsibility of DTC, the
     Property Trustee, the Issuer Trust or the Company. Neither the
     Issuer Trust or the Company nor the Property Trustee will be liable
     for any delay by DTC or any of its Participants in identifying the
     beneficial owners of the Capital Securities, and the Issuer Trust
     or the Company and the Property Trustee may conclusively rely on
     and will be protected in relying on instructions from DTC or its
     nominee for all purposes.

          Secondary market trading activity in interests in the Global
     Capital Securities will settle in immediately available funds,
     subject in all cases to the rules and procedures of DTC and its
     participants. Transfers between Participants in DTC will be
     effected in accordance with DTC's procedures, and will be settled
     in same-day funds.

          DTC has advised the Issuer Trust and the Company that it will
     take any action permitted to be taken by a holder of Capital
     Securities only at the direction of one or more Participants to
     whose account with DTC interests in the Global Capital Securities
     are credited and only in respect of such portion of the Liquidation
     Amount of the Capital Securities as to which such Participant or
     Participants has or have given such direction. However, if there is
     an Event of Default under the Trust Agreement, DTC reserves the
     right to exchange the Global Capital Securities for legended
     Capital Securities in certificated form and to distribute such
     Capital Securities to its Participants.

          The information in this section concerning DTC and its book-
     entry systems has been obtained from sources that the Issuer Trust
     and the Company believe to be reliable, but neither the Issuer
     Trust nor the Company takes responsibility for the accuracy
     thereof.

          Although DTC has agreed to the foregoing procedures to
     facilitate transfers of interest in the Global Capital Securities
     among participants in DTC, they are under no obligation to perform
     or to continue to perform such procedures, and such procedures may
     be discontinued at any time. Neither the Issuer Trust or the
     Company nor the Property Trustee will have any responsibility for
     the performance by DTC or its participants or indirect participants
     of their respective obligations under the rules and procedures
     governing their operations.

          Exchange of Book-Entry Capital Securities for Certificated
     Capital Securities. A Global Capital Security is exchangeable for
     Exchange Capital Securities in registered certificated form if (i)
     DTC (x) notifies the Issuer Trust that it is unwilling or unable to
     continue as Depositary for the Global Capital Security and the
     Issuer Trust thereupon fails to appoint a successor Depositary
     within 90 days or (y) has ceased to be a clearing agency registered
     under the Exchange Act, (ii) the Company in its sole discretion
     elects to cause the issuance of the Exchange Capital Securities in
     certificated form or (iii) there shall have occurred and be
     continuing an Event of Default or any event which after notice or
     lapse of time or both would be an Event of Default under the Trust
     Agreement. In all cases, certificated Capital Securities delivered
     in exchange for any Global Capital Security or beneficial interests
     therein will be registered in the names, and issued in any approved
     denominations, requested by or on behalf of the Depositary (in
     accordance with its customary procedures).

          Exchange of Certificated Capital Securities for Book-Entry
     Capital Securities. Other Capital Securities, which will be issued
     in certificated form, may not be exchanged for beneficial interests
     in any Global Capital Security unless such exchange occurs in
     connection with a transfer of such Other Capital Securities and the
     transferor first delivers to the Property Trustee a written
     certificate (in the form provided in the Trust Agreement) to the
     effect that such transfer will comply with the appropriate transfer
     restrictions applicable to such Capital Securities.

          Payment and Paying Agency. Payments in respect of the Exchange
     Capital Securities shall be made to DTC, which shall credit the
     relevant accounts at DTC on the applicable Distribution Dates or,
     if the Issuer Trust's Exchange Capital Securities are not held by
     DTC, such payments may be made, at the option of the Company, by
     check mailed to the address of the holder entitled thereto as such
     address shall appear on the Security Register or by wire transfer.
     The paying agent (the "Paying Agent") shall initially be the
     Property Trustee and any co-paying agent chosen by the Property
     Trustee and acceptable to the Administrators. The Paying Agent
     shall be permitted to resign as Paying Agent upon 30 days' written
     notice to the Property Trustee and the Administrators. In the event
     that the Property Trustee shall no longer be the Paying Agent, the
     Company, or if an Issuer Trust Default shall have occurred and be
     continuing, the Property Trustee shall appoint a successor (which
     shall be a bank or trust Company reasonably acceptable to the
     Administrators) to act as Paying Agent.

          First Chicago has informed the Issuer Trust that so long as it
     serves as paying agent for the Exchange Capital Securities, it
     anticipates that information regarding Distributions on the Capital
     Securities, including payment date, record date and redemption
     information, will be made available through First Chicago.

          Registrar and Transfer Agent. The Property Trustee will act as
     registrar and transfer agent for the Capital Securities.

          Registration of transfers of Capital Securities will be
     effected without charge by or on behalf of the Issuer Trust, but
     upon payment of any tax or other governmental charges that may be
     imposed in connection with any transfer or exchange. The Issuer
     Trust will not be required to register or cause to be registered
     the transfer of its Capital Securities after such Capital
     Securities have been called for redemption.

          Information Concerning the Property Trustee. The Property
     Trustee, other than during the occurrence and continuance of an
     Event of Default, undertakes to perform only such duties as are
     specifically set forth in the Trust Agreement and, after such Event
     of Default, must exercise the same degree of care and skill as a
     prudent person would exercise or use in the conduct of his or her
     own affairs. Subject to this provision, the Property Trustee is
     under no obligation to exercise any of the powers vested in it by
     the Trust Agreement at the request of any holder of Capital
     Securities unless it is offered reasonable indemnity against the
     costs, expenses and liabilities that might be incurred thereby. If
     no Event of Default has occurred and is continuing and the Property
     Trustee is required to decide between alternative courses of
     action, construe ambiguous provisions in the Trust Agreement or is
     unsure of the application of any provision of the Trust Agreement,
     and the matter is not one on which holders of Capital Securities
     are entitled under the Trust Agreement to vote, then the Property
     Trustee shall take such action as it deems advisable and in the
     best interests of the holders of the Trust Securities and will have
     no liability except for its own bad faith, negligence or willful
     misconduct.

          For information concerning the relationship between First
     Chicago, the Property Trustee, and the Company, see "Description of
     Exchange Junior Subordinated Debentures Information Concerning the
     Debenture Trustee."

          Miscellaneous. The Administrators and the Property Trustee are
     authorized and directed to conduct the affairs of and to operate
     the Issuer Trust in such a way that the Issuer Trust will not be
     deemed to be an "investment Company" required to be registered
     under the Investment Company Act or classified as an association
     taxable as a Corporation for United States federal income tax
     purposes and so that the Junior Subordinated Debentures will be
     treated as indebtedness of the Company for United States federal
     income tax purposes. In this connection, the Property Trustee and
     the holders of Common Securities are authorized to take any action,
     not inconsistent with applicable law, the certificate of trust of
     the Issuer Trust or the Trust Agreement, that the Property Trustee
     and the holders of Common Securities determine in their discretion
     to be necessary or desirable for such purposes, as long as such
     action does not materially adversely affect the interests of the
     holders of the Capital Securities.

          Holders of the Capital Securities have no preemptive or
     similar rights.

          The Issuer Trust may not borrow money or issue debt or
     mortgage or pledge any of its assets.

     DESCRIPTION OF EXCHANGE JUNIOR SUBORDINATED DEBENTURES

          The Exchange Junior Subordinated Debentures are to be issued
     under the Junior Subordinated Indenture, between the Company and
     the Debenture Trustee. This summary of certain terms and provisions
     of the Exchange Junior Subordinated Debentures and the Junior
     Subordinated Indenture does not purport to be complete and is
     subject to, and is qualified in its entirety by reference to, the
     Junior Subordinated Indenture, a copy of which will be available
     from the Debenture Trustee upon request. Whenever particular
     defined terms of the Junior Subordinated Indenture (as supplemented
     or amended from time to time) are referred to herein, such defined
     terms are incorporated herein by reference.

          General. Concurrently with the issuance of the Exchange
     Capital Securities, the Issuer Trust invested the proceeds thereof,
     together with the consideration paid by the Company for the Common
     Securities, in the Original Junior Subordinated Debentures issued
     by the Company. The Exchange Junior Subordinated Debentures will
     bear interest, accruing from July 15, 1997, at the variable annual
     rate of LIBOR plus .91% on the principal amount thereof, payable
     quarterly in arrears on January 15, April 15, July 15 and October
     15 of each year (each, an "Interest Payment Date"), commencing
     October 15, 1997, to the person in whose name each Exchange Junior
     Subordinated Debenture is registered at the close of business on
     the January 1, April 1, July 1 and October 1 next preceding such
     Interest Payment Date. It is anticipated that, until the
     liquidation, if any, of the Issuer Trust, each Exchange Junior
     Subordinated Debenture will be held in the name of the Property
     Trustee for the benefit of the holders of the Trust Securities. The
     amount of interest payable for any period will be computed on the
     basis of the actual number of days in the applicable payment period
     (which actual number of days shall include the first day but
     exclude the last day of such payment period) divided by 360. In the
     event that any date on which interest is payable on the Exchange
     Junior Subordinated Debentures is not a Business Day, then payment
     of the interest payable on such date will be made on the next
     succeeding day that is a Business Day (and without any interest or
     other payment in respect of any such delay), except that, if such
     Business Day is in the next succeeding calendar year, such payment
     shall be made on the immediately preceding Business Day, in each
     case with the same force and effect as if made on the date such
     payment was originally payable. Accrued interest that is not paid
     on the applicable Interest Payment Date will bear additional
     interest on the amount thereof (to the extent permitted by law) at
     the variable rate per annum of LIBOR plus .91% on the principal
     amount thereof from the relevant payment date for such interest.
     The term "interest" as used herein shall include quarterly interest
     payments, interest on quarterly interest payments not paid on the
     applicable Interest Payment Date and Additional Sums (as defined
     below), as applicable.

          The Exchange Junior Subordinated Debentures will mature on the
          Stated Maturity.

          The Exchange Junior Subordinated Debentures will rank pari
     passu with the Original Junior Subordinated Debentures. The
     Exchange Junior Subordinated Debentures will be unsecured and will
     rank junior and be subordinate in right of payment to all Senior
     Indebtedness of the Company. Because the Company is a holding
     company, the right of the Company to participate in any
     distribution of assets of any subsidiary, upon such subsidiary's
     liquidation or reorganization or otherwise (and thus the ability of
     holders of the Capital Securities to benefit indirectly from such
     distribution), is subject to the prior claims of creditors of that
     subsidiary, except to the extent that the Company may itself be
     recognized as a creditor of that subsidiary. Accordingly, the
     Exchange Junior Subordinated Debentures will be effectively
     subordinated to all existing and future liabilities of the
     Company's subsidiaries, and holders of Exchange Junior Subordinated
     Debentures should look only to the assets of the Company for
     payments on the Exchange Junior Subordinated Debentures. See "HSB
     Group, Inc." The Junior Subordinated Indenture does not limit the
     incurrence or issuance of other secured or unsecured debt of the
     Company, including Senior Indebtedness, whether under the Junior
     Subordinated Indenture or any existing or other indenture that the
     Company may enter into in the future or otherwise. See "
     Subordination."

          Determination of Interest Rate. First Chicago, as Calculation
     Agent (the "Calculation Agent"), will calculate the interest rate
     for each quarterly interest period based on LIBOR determined as of
     two London Business Days (defined as any day, other than a Saturday
     or Sunday, on which banks are open for business in London) prior to
     the first day of such interest period (each, a "Determination
     Date"). "LIBOR" means, with respect to a quarterly interest period
     relating to an Interest Payment Date (in the following order of
     priority):

          (1) the rate (expressed as a percentage per annum) for
     Eurodollar deposits having a three-month maturity that appears on
     Telerate Page 3750 as of 11:00 a.m. (London time) on the related
     Determination Date;

          (2) if such rate does not appear on Telerate Page 3750 as of
     11:00 a.m. (London time) on the related Determination Date, LIBOR
     will be the arithmetic mean (if necessary rounded upwards to the
     nearest whole multiple of 0.00001%) of the rates (expressed as
     percentages per annum) for Eurodollar deposits having a three-
     month maturity that appear on Reuters Monitor Money Rates Page
     LIBOR ("Reuters Page LIBOR") as of 11:00 a.m. (London time) on such
     Determination Date;

          (3) if such rate does not appear on Reuters Page LIBOR as of
     11:00 a.m. (London time) on the related Determination Date, the
     Calculation Agent will request the principal London offices of four
     leading banks in the London interbank market to provide such banks'
     offered quotations (expressed as percentages per annum) to prime
     banks in the London interbank market for Eurodollar deposits having
     a three-month maturity as of 11:00 a.m. (London time) on such
     Determination Date. If at least two quotations are provided, LIBOR
     will be the arithmetic mean (if necessary rounded upwards to the
     nearest whole multiple of 0.00001%) of such quotations;

          (4) if fewer than two such quotations are provided as
     requested in clause (3) above, the Calculation Agent will request
     four major New York City banks to provide such banks' offered
     quotations (expressed as percentages per annum) to leading European
     banks for loans in Eurodollars having a three-month maturity as of
     11:00 a.m. (London time) on such Determination Date. If at least
     two such quotations are provided, LIBOR will be the arithmetic mean
     (if necessary rounded upwards to the nearest whole multiple of
     0.00001%) of such quotations; and

          (5) if fewer than two such quotations are provided as
     requested in clause (4) above, LIBOR will be LIBOR as determined on
     the previous Determination Date.

          If the rate for Eurodollar deposits having a three-month
     maturity that initially appears on Telerate Page 3750 or Reuters
     Page LIBOR, as the case may be, as of 11:00 a.m. (London time) on
     the related Determination Date is superseded on Telerate Page 3750
     or Reuters Page LIBOR, as the case may be, by a corrected rate
     before 12:00 noon (London time) on such Determination Date, the
     corrected rate as so substituted on the applicable page will be the
     applicable LIBOR for such Determination Date.

          Absent manifest error, the Calculation Agent's determination
     of LIBOR and its calculation of the applicable interest rate for
     each interest period will be final and binding. Investors may
     obtain the interest rates for the current and preceding interest
     period by writing or calling Corporate Trust Administration at the
     Calculation Agent at One First National Plaza, Suite 0126, Chicago,
     Illinois 60670-0126 (telephone (312) 407-4660).

          Option To Extend Interest Payment Period. So long as no Event
     of Default under the Junior Subordinated Indenture has occurred and
     is continuing, the Company has the right under the Junior
     Subordinated Indenture at any time during the term of the Exchange
     Junior Subordinated Debentures to defer the payment of interest at
     any time or from time to time for a period not exceeding 20
     consecutive quarterly periods with respect to each Extension
     Period, provided that no Extension Period may extend beyond the
     Stated Maturity of the Exchange Junior Subordinated Debentures. At
     the end of such Extension Period, the Company must pay all interest
     then accrued and unpaid (together with interest thereon at the
     variable annual rate of LIBOR plus .91% on the principal amount
     thereof, compounded quarterly from the relevant payment date for
     such interest. The amount of additional interest payable for any
     full interest period will be computed by dividing the rate per
     annum by four. During an Extension Period, interest will continue
     to accrue and holders of Exchange Junior Subordinated Debentures
     (or holders of Capital Securities while outstanding) will be
     required to accrue interest income for United States federal income
     tax purposes. See "Certain Federal Income Tax Consequences Interest
     Income and Original Issue Discount."

          During any such Extension Period, the Company may not, and may
     not permit any subsidiary of the Company to, (i) declare or pay any
     dividends or distributions on, or redeem, purchase, acquire, or
     make a liquidation payment with respect to, any of the Company's
     capital stock or (ii) make any payment of principal, interest or
     premium, if any, on or repay, repurchase or redeem any debt
     securities of the Company that rank pari passu in all respects with
     or junior in interest to the Exchange Junior Subordinated
     Debentures or (iii) make any guarantee payments with respect to any
     guarantee by the Company of the debt securities of any subsidiary
     of the Company if such guarantee ranks pari passu with or junior in
     interest to the Exchange Junior Subordinated Debentures (other than
     (a) dividends or distributions in common stock of the Company, (b)
     any declaration of a dividend in connection with the implementation
     of a stockholders' rights plan, or the issuance of stock under any
     such plan in the future, or the redemption or repurchase of any
     such rights pursuant thereto, (c) payments under the Guarantee and
     (d) purchases of common stock related to the issuance of common
     stock or rights under any of the Company's or its subsidiaries'
     benefit plans for their directors, officers or employees). Prior to
     the termination of any such Extension Period, the Company may
     further defer the payment of interest, provided that no Extension
     Period may exceed 20 consecutive quarterly periods or extend beyond
     the Stated Maturity of the Exchange Junior Subordinated Debentures.
     Upon the termination of any such Extension Period and the payment
     of all amounts then due on any Interest Payment Date, the Company
     may elect to begin a new Extension Period subject to the above
     requirements. No interest shall be due and payable during an
     Extension Period, except at the end thereof. The Company must give
     the Property Trustee and the Debenture Trustee notice of its
     election of such Extension Period at least one Business Day prior
     to the earlier of (i) the date the Distributions on the Capital
     Securities would have been payable except for the election to begin
     such Extension Period or (ii) the date the Property Trustee is
     required to give notice to any applicable self-regulatory
     organization or to holders of the Capital Securities of the record
     date or (iii) the date such Distributions are payable, but in any
     event not less than one Business Day prior to such record date. The
     Property Trustee shall give notice of the Company's election to
     begin a new Extension Period to the holders of the Capital
     Securities. There is no limitation on the number of times that the
     Company may elect to begin an Extension Period.

          Redemption. The Exchange Junior Subordinated Debentures are
     redeemable prior to maturity at the option of the Company (i) on or
     after July 15, 2007, in whole or in part at any time or in part
     from time to time, or (ii) in whole (but not in part) prior to July
     15, 2007, and within 90 days following the occurrence of a Tax
     Event (as defined under "Description of Exchange Capital Securities
     Redemption"), at a redemption price equal to 100% of the principal
     amount of the Exchange Junior Subordinated Debentures so redeemed
     plus accrued and unpaid interest thereon to date of redemption. The
     proceeds of any such redemption will be used by the Issuer Trust to
     redeem the Exchange Capital Securities.

          Conditional Right to Shorten Maturity upon a Tax Event. The
     maturity of the Exchange Junior Subordinated Debentures may be
     shortened at the option of the Company under the circumstances
     described under "Description of Exchange Capital Securities
     Conditional Right to Shorten Maturity or Redeem upon a Tax Event."
     Upon the exercise of the right to shorten the maturity of the
     Exchange Junior Subordinated Debentures, the Company will no longer
     have the right to redeem the Exchange Junior Subordinated
     Debentures prior to the new Stated Maturity upon the occurrence of
     a Tax Event or to further shorten the maturity of the Exchange
     Junior Subordinated Debentures.

          See "Certain Federal Income Tax Consequences Possible Tax Law
     Changes" for a discussion of certain legislative proposals that, if
     adopted, could give rise to a Tax Event, which may permit the
     Company to shorten the maturity of the Exchange Junior Subordinated
     Debentures.

          Additional Sums. If the Issuer Trust is required to pay any
     additional taxes, duties or other governmental charges as a result
     of a Tax Event, the Company will pay as additional amounts on the
     Exchange Junior Subordinated Debentures such amounts as shall be
     required so that the Distributions payable by the Issuer Trust
     shall not be reduced as a result of any such additional taxes,
     duties or other governmental charges. The Company has covenanted in
     the Junior Subordinated Indenture that, if and so long as (i) the
     Issuer Trust is the holder of all Junior Subordinated Debentures
     and (ii) a Tax Event in respect of the Issuer Trust has occurred
     and is continuing, the Company will pay to the Issuer Trust such
     Additional Sums (as defined under "Description of Exchange Capital
     Securities Redemption").

          Registration, Denomination and Transfer. The Exchange Junior
     Subordinated Debentures will be registered in the name of the
     Issuer Trust. In the event that the Exchange Junior Subordinated
     Debentures are distributed to holders of Exchange Capital
     Securities, it is anticipated that the depositary arrangements for
     the Exchange Junior Subordinated Debentures will be substantially
     identical to those in effect for the Exchange Capital Securities.
     See "Description of Exchange Capital Securities Book Entry,
     Delivery and Form."

          Although DTC has agreed to the foregoing procedures, it is
     under no obligation to perform or continue to perform such
     procedures, and such procedures may be discontinued at any time. If
     DTC is at any time unwilling or unable to continue as depositary
     and a successor depositary is not appointed by the Company within
     90 days, the Company will cause the Exchange Junior Subordinated
     Debentures to be issued in definitive registered form.

          Payments on Junior Subordinated Debentures represented by a
     global security will be made to Cede, the nominee for DTC, as the
     depositary for the Junior Subordinated Debentures. In the event
     Junior Subordinated Debentures are issued in definitive registered
     form, principal and interest will be payable, the transfer of the
     Junior Subordinated Debentures will be registrable, and Junior
     Subordinated Debentures will be exchangeable for Junior
     Subordinated Debentures of other denominations of a like aggregate
     principal amount, at the corporate trust office of the Debenture
     Trustee in New York, New York, or at the offices of any paying
     agent or transfer agent appointed by the Company, provided that
     payment of interest may be made at the option of the Company by
     check mailed to the address of the persons entitled thereto or by
     wire transfer.

          The Exchange Junior Subordinated Debentures will be issuable
     only in registered form without coupons. Exchange Junior
     Subordinated Debentures will be exchangeable for other Junior
     Subordinated Debentures, of any authorized denominations, of a like
     aggregate principal amount.

          Junior Subordinated Debentures may be presented for exchange
     as provided above, and may be presented for registration of
     transfer (with the form of transfer endorsed thereon, or a
     satisfactory written instrument of transfer, duly executed), at the
     office of the Security Registrar or at the office of any transfer
     agent designated by the Company for such purpose without service
     charge and upon payment of any taxes and other governmental charges
     as described in the Junior Subordinated Indenture. The Company will
     appoint the Debenture Trustee as Security Registrar under the
     Junior Subordinated Indenture. The Company may at any time
     designate additional transfer agents with respect to the Junior
     Subordinated Debentures.

          In the event of any redemption, neither the Company nor the
     Debenture Trustee shall be required to (i) issue, register the
     transfer of or exchange Junior Subordinated Debentures during a
     period beginning at the opening of business 15 days before the day
     of selection for redemption of Junior Subordinated Debentures and
     ending at the close of business on the day of mailing of the
     relevant notice of redemption or (ii) transfer or exchange any
     Junior Subordinated Debentures so selected for redemption, except,
     in the case of any Junior Subordinated Debentures being redeemed in
     part, any portion thereof not to be redeemed.

          Any moneys deposited with the Debenture Trustee or any paying
     agent, or then held by the Company in trust, for the payment of the
     principal of (and premium, if any) or interest on any Junior
     Subordinated Debenture and remaining unclaimed for two years after
     such principal (and premium, if any) or interest has become due and
     payable shall, at the request of the Company, be repaid to the
     Company and the holder of such Junior Subordinated Debenture shall
     thereafter look, as a general unsecured creditor, only to the
     Company for payment thereof.

          Restrictions on Certain Payments; Certain Covenants of the
     Company. The Company has covenanted that it will not, and will not
     permit any subsidiary of the Company to, (i) declare or pay any
     dividends or distributions on, or redeem, purchase, acquire, or
     make a liquidation payment with respect to, any of the Company's
     capital stock or (ii) make any payment of principal of or interest
     or premium, if any, on or repay, repurchase or redeem any debt
     securities of the Company that rank pari passu in all respects with
     or junior in interest to the Exchange Junior Subordinated
     Debentures or make any guarantee payments with respect to any
     guarantee by the Company of the debt securities of any subsidiary
     of the Company if such guarantee ranks pari passu with or junior in
     interest to the Exchange Junior Subordinated Debentures (other than
     (a) dividends or distributions in common stock of the Company, (b)
     any declaration of a dividend in connection with the implementation
     of a stockholders' rights plan, or the issuance of stock under any
     such plan in the future, or the redemption or repurchase of any
     such rights pursuant thereto, (c) payments under the Guarantee and
     (d) purchases of common stock related to the issuance of common
     stock or rights under any of the Company's or its subsidiaries'
     benefit plans for their directors, officers or employees), if at
     such time (i) there shall have occurred any event of which the
     Company has actual knowledge that (a) with the giving of notice or
     the lapse of time, or both, would constitute a Debenture Event of
     Default and (b) in respect of which the Company shall not have
     taken reasonable steps to cure, (ii) if such Junior Subordinated
     Debentures are held by the Issuer Trust, the Company shall be in
     default with respect to its payment of any obligations under the
     Guarantee or (iii) the Company shall have given notice of its
     selection of an Extension Period as provided in the Junior
     Subordinated Indenture with respect to the Exchange Junior
     Subordinated Debentures and shall not have rescinded such notice,
     or such Extension Period, or any extension thereof, shall be
     continuing.

          The Company has covenanted in the Junior Subordinated
     Indenture, (i) to maintain directly or indirectly 100% ownership of
     the Common Securities of the Issuer Trust, provided that certain
     successors which are permitted pursuant to the Junior Subordinated
     Indenture may succeed to the Company's ownership of the Common
     Securities, (ii) as holder of the Common Securities, not to
     voluntarily terminate, wind-up or liquidate the Issuer Trust,
     except (a) in connection with a distribution of Junior Subordinated
     Debentures to the holders of the Capital Securities in liquidation
     of the Issuer Trust or (b) in connection with certain mergers,
     consolidations or amalgamations permitted by the Trust Agreement
     and (iii) to use its reasonable efforts, consistent with the terms
     and provisions of the Trust Agreement, to cause the Issuer Trust to
     remain classified as a grantor trust and not as an association
     taxable as a Corporation for United States federal income tax
     purposes.

          Modification of Junior Subordinated Indenture. From time to
     time the Company and the Debenture Trustee may, without the consent
     of the holders of the Exchange Junior Subordinated Debentures,
     amend, waive or supplement the Junior Subordinated Indenture for
     specified purposes, including, among other things, curing
     ambiguities, defects or inconsistencies (provided that any such
     action does not materially adversely affect the interests of the
     holders of the Exchange Junior Subordinated Debentures or the
     holders of the Exchange Capital Securities so long as they remain
     outstanding) and qualifying, or maintaining the qualification of,
     the Junior Subordinated Indenture under the Trust Indenture Act of
     1939. The Junior Subordinated Indenture contains provisions
     permitting the Company and the Debenture Trustee, with the consent
     of the holders of not less than a majority in principal amount of
     the Exchange Junior Subordinated Debentures, to modify the Junior
     Subordinated Indenture in a manner affecting the rights of the
     holders of the Exchange Junior Subordinated Debentures; provided,
     that no such modification may, without the consent of the holder of
     each outstanding Exchange Junior Subordinated Debenture so
     affected, (i) change the Stated Maturity of the Exchange Junior
     Subordinated Debentures, or reduce the principal amount thereof or
     any premium payable upon redemption, or reduce the rate or extend
     the time of payment of interest thereon or (ii) reduce the
     percentage of principal amount of Exchange Junior Subordinated
     Debentures, the holders of which are required to consent to any
     such modification of the Subordinated Indenture, provided that, so
     long as any of the Exchange Capital Securities remain outstanding,
     no such modification may be made that adversely affects the holders
     of such Exchange Capital Securities in any material respect, and no
     termination of the Junior Subordinated Indenture may occur, and no
     waiver of any Debenture Event of Default or compliance with any
     covenant under the Junior Subordinated Indenture may be effective,
     without the prior consent of the holders of at least a majority of
     the aggregate Liquidation Amount of such Exchange Capital
     Securities unless and until the principal of the Exchange Junior
     Subordinated Debentures and all accrued and unpaid interest thereon
     have been paid in full and certain other conditions are satisfied.

          Debenture Events of Default. The Junior Subordinated Indenture
     provides that any one or more of the following described events
     with respect to the Exchange Junior Subordinated Debentures that
     has occurred and is continuing constitutes a Debenture Event of
     Default with respect to the Exchange Junior Subordinated
     Debentures:

          (i) failure for 30 days to pay any interest on the Exchange
     Junior Subordinated Debentures when due (subject to the deferral of
     any due date in the case of an Extension Period); or

          (ii) failure to pay any principal or premium, if any, on the
     Exchange Junior Subordinated Debentures when due whether at
     maturity, upon redemption, by declaration of acceleration or
     otherwise; or

          (iii) failure to observe or perform in any material respect
     certain other covenants contained in the Junior Subordinated
     Indenture for a period of 90 days after there has been given, by
     registered or certified mail, to the Company from the Debenture
     Trustee or the holders of at least 25% in aggregate outstanding
     principal amount of the outstanding Junior Subordinated Debentures
     a written notice specifying such default or breach and requiring it
     to be remedied and stating that such notice is a "Notice of
     Default"; or

          (iv) certain events in bankruptcy, insolvency or
     reorganization of the Company.

          The holders of a majority in aggregate outstanding principal
     amount of Junior Subordinated Debentures have the right to direct
     the time, method and place of conducting any proceeding for any
     remedy available to the Debenture Trustee. The Debenture Trustee or
     the holders of not less than 25% in aggregate outstanding principal
     amount of Junior Subordinated Debentures may declare the principal
     and accrued interest due and payable immediately upon a Debenture
     Event of Default, and, should the Debenture Trustee or such holders
     of Junior Subordinated Debentures fail to make such declaration,
     the holders of at least 25% in aggregate Liquidation Amount of the
     Capital Securities shall have such right. The holders of a majority
     in aggregate outstanding principal amount of Junior Subordinated
     Debentures may annul such declaration and waive the default if the
     default (other than the non-payment of the principal of Junior
     Subordinated Debentures which has become due solely by such
     acceleration) has been cured and a sum sufficient to pay all
     matured installments of interest and principal due otherwise than
     by acceleration has been deposited with the Debenture Trustee.
     Should the holders of Junior Subordinated Debentures fail to annul
     such declaration and waive such default, the holders of a majority
     in aggregate Liquidation Amount of the Capital Securities shall
     have such right.

          The holders of a majority in aggregate outstanding principal
     amount of the Junior Subordinated Debentures affected thereby may,
     on behalf of the holders of all the Junior Subordinated Debentures,
     waive any past default, except a default in the payment of
     principal or interest (unless such default has been cured and a sum
     sufficient to pay all matured installments of interest and
     principal due otherwise than by acceleration has been deposited
     with the Debenture Trustee) or a default in respect of a covenant
     or provision which under the Junior Subordinated Indenture cannot
     be modified or amended without the consent of the holder of each
     outstanding Junior Subordinated Debenture. Should the holders of
     such Junior Subordinated Debentures fail to waive any such past
     default, the holders of a majority in aggregate Liquidation Amount
     of the Capital Securities shall have such right. The Company is
     required to file annually with the Debenture Trustee a certificate
     as to whether or not the Company is in compliance with all the
     conditions and covenants applicable to it under the Junior
     Subordinated Indenture.

          In case a Debenture Event of Default shall occur and be
     continuing, the Property Trustee will have the right to declare the
     principal of and the accrued interest on the Junior Subordinated
     Debentures, and any other amounts payable under the Junior
     Subordinated Indenture, to be forthwith due and payable and to
     enforce its other rights as a creditor with respect to the Junior
     Subordinated Debentures.

          Enforcement of Certain Rights by Holders of Capital
     Securities. If a Debenture Event of Default has occurred and is
     continuing and such event is attributable to the failure of the
     Company to pay interest or principal on the Exchange Junior
     Subordinated Debentures on the date such interest or principal is
     otherwise payable, a holder of Exchange Capital Securities may
     institute a Direct Action. The Company may not amend the Junior
     Subordinated Indenture to remove the foregoing right to bring a
     Direct Action without the prior written consent of the holders of
     all of the Capital Securities. The Company shall have the right
     under the Exchange Junior Subordinated Indenture to set-off any
     payment made to such holder of Capital Securities by the Company in
     connection with a Direct Action.

          The holders of the Exchange Capital Securities would not be
     able to exercise directly any remedies available to the holders of
     the Exchange Junior Subordinated Debentures other than those set
     forth in the preceding paragraph unless there shall have been an
     Event of Default under the Trust Agreement. See "Description of
     Exchange Capital Securities Events of Default; Notice."

          Consolidation, Merger, Sale of Assets and Other Transactions.
     The Junior Subordinated Indenture provides that the Company shall
     not consolidate with or merge into any other Person or convey,
     transfer or lease its properties and assets substantially as an
     entirety to any Person, and no Person shall consolidate with or
     merge into the Company or convey, transfer or lease its properties
     and assets substantially as an entirety to the Company, unless (i)
     in case the Company consolidates with or merges into another Person
     or conveys or transfers its properties and assets substantially as
     an entirety to any Person, the successor Person is organized under
     the laws of the United States or any state or the District of
     Columbia, and such successor Person expressly assumes the Company's
     obligations on the Exchange Junior Subordinated Debentures issued
     under the Junior Subordinated Indenture; (ii) immediately after
     giving effect thereto, no Debenture Event of Default, and no event
     which, after notice or lapse of time or both, would become a
     Debenture Event of Default, shall have occurred and be continuing;
     (iii) such transaction is permitted under the Trust Agreement and
     Guarantee and does not give rise to any breach or violation of the
     Trust Agreement or Guarantee; and (iv) certain other conditions as
     prescribed in the Junior Subordinated Indenture are met.

          The general provisions of the Junior Subordinated Indenture do
     not afford holders of the Exchange Junior Subordinated Debentures
     protection in the event of a highly leveraged or other transaction
     involving the Company that may adversely affect holders of the
     Exchange Junior Subordinated Debentures.

          Satisfaction and Discharge. The Junior Subordinated Indenture
     provides that when, among other things, all Junior Subordinated
     Debentures not previously delivered to the Debenture Trustee for
     cancellation (i) have become due and payable or (ii) will become
     due and payable at their Stated Maturity within one year, and the
     Company deposits or causes to be deposited with the Debenture
     Trustee funds, in trust, for the purpose and in an amount
     sufficient to pay and discharge the entire indebtedness on the
     Junior Subordinated Debentures not previously delivered to the
     Debenture Trustee for cancellation, for the principal (and premium,
     if any) and interest and Additional Sums to the date of the deposit
     or to the Stated Maturity, as the case may be, then the
     Subordinated Indenture will cease to be of further effect (except
     as to the Company's obligations to pay all other sums due pursuant
     to the Junior Subordinated Indenture and to provide the officers'
     certificates and opinions of counsel described therein), and the
     Company will be deemed to have satisfied and discharged the Junior
     Subordinated Indenture.

          Subordination. The Exchange Junior Subordinated Debentures
     shall be subordinate and junior in right of payment, to the extent
     set forth in the Junior Subordinated Indenture, to all Senior
     Indebtedness (as defined below) of the Company. In the event that
     the Company shall default in the payment of any principal, premium,
     if any, or interest, if any, on any Senior Indebtedness when the
     same becomes due and payable, whether at maturity or at a date
     fixed for prepayment or by declaration of acceleration or
     otherwise, then, unless and until such default shall have been
     cured or waived or shall have ceased to exist or all Senior
     Indebtedness shall have been paid, no direct or indirect payment
     (in cash, property, securities, by set-off or otherwise) shall be
     made or agreed to be made for principal, premium, if any, or
     interest, if any, on the Exchange Junior Subordinated Debentures,
     or in respect of any redemption, repayment, retirement, purchase or
     other acquisition of any of the Exchange Junior Subordinated
     Debentures.

          "Debt" means with respect to the Company, whether recourse is
     to all or a portion of the assets of the Company and whether or not
     contingent, (i) every obligation of the Company for money borrowed;
     (ii) every obligation of the Company evidenced by bonds,
     debentures, notes or other similar instruments, including
     obligations incurred in connection with the acquisition of
     property, assets or businesses; (iii) every reimbursement
     obligation of the Company with respect to letters of credit,
     bankers' acceptances or similar facilities issued for the account
     of the Company; (iv) every obligation of the Company issued or
     assumed as the deferred purchase price of property or services (but
     excluding trade accounts payable or accrued liabilities, arising in
     the ordinary course of business); (v) every capital lease
     obligation of the Company; (vi) all indebtedness of the Company
     whether incurred on or prior to the date of the Junior Subordinated
     Indenture or thereafter incurred, for claims in respect of
     derivative products, including interest rate, foreign exchange rate
     and commodity forward contracts, options and swaps and similar
     arrangements; and (vii) every obligation of the type referred to in
     clauses (i) through (vi) of another Person and all dividends of
     another Person the payment of which, in either case, the Company
     has guaranteed or is responsible or liable for, directly or
     indirectly, as obligor or otherwise.

          "Senior Indebtedness" means the principal of (and premium, if
     any) and interest, if any (including interest accruing on or after
     the filing of any petition in bankruptcy or for reorganization
     relating to the Company whether or not such claim for post-petition
     interest is allowed in such proceeding), on Debt of the Company,
     whether incurred on or prior to the date of the Junior Subordinated
     Indenture or thereafter incurred, unless, in the instrument
     creating or evidencing the same or pursuant to which the same is
     outstanding, it is provided that such obligations are not superior
     in right of payment to the Junior Subordinated Debentures;
     provided, however, that Senior Indebtedness shall not be deemed to
     include (i) any Debt of the Company which when incurred and without
     respect to any election under Section 1111(b) of the United States
     Bankruptcy Code of 1978, as amended, was without recourse to the
     Company, (ii) any Debt of the Company to any of its subsidiaries,
     (iii) Debt to any employee of the Company and (iv) any other debt
     securities issued pursuant to the Junior Subordinated Indenture.

          In the event of (i) any insolvency, bankruptcy, receivership,
     liquidation, reorganization, readjustment, composition or other
     similar proceeding relating to the Company, its creditors or its
     property, (ii) any proceeding for the liquidation, dissolution or
     other winding up of the Company, voluntary or involuntary, whether
     or not involving insolvency or bankruptcy proceedings, (iii) any
     assignment by the Company for the benefit of creditors or (iv) any
     other marshalling of the assets of the Company, all Senior
     Indebtedness (including any interest thereon accruing after the
     commencement of any such proceedings) shall first be paid in full
     before any payment or distribution, whether in cash, securities or
     other property, shall be made on account of the principal of or
     premium, if any, or interest, if any, on the Junior Subordinated
     Debentures. In such event, any payment or distribution on account
     of the principal of or premium, if any, or interest, if any, on the
     Junior Subordinated Debentures, whether in cash, securities or
     other property (other than securities of the Company or any other
     corporation provided for by a plan of reorganization or
     readjustment the payment of which is subordinate, at least to the
     extent provided in the subordination provisions with respect to the
     Junior Subordinated Debentures, to the payment of all Senior
     Indebtedness at the time outstanding, and to any securities issued
     in respect thereof under any such plan of reorganization or
     readjustment), which would otherwise (but for the subordination
     provisions) be payable or deliverable in respect of the Junior
     Subordinated Debentures shall be paid or delivered directly to the
     holders of Senior Indebtedness in accordance with the priorities
     then existing among such holders until all Senior Indebtedness
     (including any interest thereon accruing after the commencement of
     any such proceedings) shall have been paid in full.

          In the event of any such proceeding, after payment in full of
     all sums owing with respect to Senior Indebtedness, the holders of
     Junior Subordinated Debentures, together with the holders of any
     obligations of the Company ranking on a parity with the Junior
     Subordinated Debentures, shall be entitled to be paid from the
     remaining assets of the Company the amounts at the time due and
     owing on account of unpaid principal of and premium, if any, and
     interest, if any, on the Junior Subordinated Debentures and such
     other obligations before any payment or other distribution, whether
     in cash, property or otherwise, shall be made on account of any
     capital stock or obligations of the Company ranking junior to the
     Junior Subordinated Debentures and such other obligations. If any
     payment or distribution on account of the principal of or interest
     on the Junior Subordinated Debentures of any character or any
     security, whether in cash, securities or other property (other than
     securities of the Company or any other corporation provided for by
     a plan of reorganization or readjustment the payment of which is
     subordinate, at least to the extent provided in the subordination
     provisions with respect to the Junior Subordinated Debentures, to
     the payment of all Senior Indebtedness at the time outstanding and
     to any securities issued in respect thereof under any such plan of
     reorganization or readjustment) shall be received by any holder of
     any Junior Subordinated Debentures in contravention of any of the
     terms hereof and before all the Senior Indebtedness shall have been
     paid in full, such payment or distribution or security shall be
     received in trust for the benefit of, and shall be paid over or
     delivered and transferred to, the holders of the Senior
     Indebtedness at the time outstanding in accordance with the
     priorities then existing among such holders for application to the
     payment of all Senior Indebtedness remaining unpaid to the extent
     necessary to pay all such Senior Indebtedness in full. By reason of
     such subordination, in the event of the insolvency of the Company,
     holders of Senior Indebtedness may receive more, ratably, and
     holders of the Junior Subordinated Debentures having a claim
     pursuant to such securities may receive less, ratably, than the
     other creditors of the Company. Such subordination will not prevent
     the occurrence of any Event of Default in respect of the Junior
     Subordinated Debentures.

          The Junior Subordinated Indenture places no limitation on the
     amount of additional Senior Indebtedness that may be incurred by
     the Company. The Company expects from time to time to incur
     additional indebtedness constituting Senior Indebtedness.

          Governing Law. The Junior Subordinated Indenture and the
     Exchange Junior Subordinated Debentures will be governed by and
     construed in accordance with the laws of the State of New York.

          Information Concerning the Debenture Trustee. The Debenture
     Trustee is under no obligation to exercise any of the powers vested
     in it by the Junior Subordinated Indenture at the request of any
     holder of Exchange Junior Subordinated Debentures, unless offered
     reasonable indemnity by such holder against the costs, expenses and
     liabilities which might be incurred thereby. The Debenture Trustee
     is not required to expend or risk its own funds or otherwise incur
     personal financial liability in the performance of its duties if
     the Debenture Trustee reasonably believes that repayment or
     adequate indemnity is not reasonably assured to it.

          First Chicago, Debenture Trustee, also serves as issuing agent
     with respect to certain negotiable certificates of deposit issued
     by the Company's subsidiaries. In addition, the Company and certain
     of its affiliates maintain deposit accounts and/or conduct other
     banking transactions with First Chicago.

          Covenant to Pay Trust Expenses. The Indenture provides that
     the Company will irrevocably and unconditionally guarantee to each
     person or entity to whom the Issuer Trust becomes indebted or
     liable, the full payment of any costs, expenses or liabilities of
     the Issuer Trust, other than obligations of the Issuer Trust to pay
     to the holders of the Capital Securities or other similar interests
     in the Issuer Trust of the amounts due such holders pursuant to the
     terms of the Capital Securities or such other similar interests, as
     the case may be. The obligation of the Company includes the payment
     of fees and expenses related to (i) the offering of the Trust
     Securities and the Subordinated Debentures, (ii) the organization,
     maintenance and dissolution of the Issuer Trust, (iii) the
     retention of the Debenture Trustee, Issuer Trustee, Delaware
     Trustee, Property Trustee, the Calculation Agent and Administrative
     Trustees and (iv) the enforcement by the Property Trustee of the
     rights of the holders of the Capital Securities. The payment of
     such fees and expenses will be fully and unconditionally guaranteed
     by the Company. The obligations to guarantee payment of such
     expenses of the Issuer Trust will constitute an unsecured
     obligation of the Company and will rank subordinate and junior in
     right of payment to all Senior Indebtedness of the Company in the
     same manner as Junior Subordinated Debentures.

     DESCRIPTION OF EXCHANGE GUARANTEE

          An Exchange Guarantee will be executed and delivered by the
     Company concurrently with the issuance by the Issuer Trust of its
     Capital Securities for the benefit of the holders from time to time
     of such Exchange Capital Securities. First Chicago will act as
     trustee ("Guarantee Trustee") under the Exchange Guarantee. This
     summary of certain provisions of the Exchange Guarantee does not
     purport to be complete and is subject to, and qualified in its
     entirety by reference to, all of the provisions of the Exchange
     Guarantee Agreement, including the definitions therein of certain
     terms. A copy of the Exchange Guarantee is available upon request
     from the Guarantee Trustee. The Guarantee Trustee will hold the
     Exchange Guarantee for the benefit of the holders of the Exchange
     Capital Securities.

          General. The Company will irrevocably agree to pay in full on
     a subordinated basis, to the extent set forth herein, the Guarantee
     Payments (as defined below) to the holders of the Exchange Capital
     Securities, as and when due, regardless of any defense, right of
     set-off or counterclaim that such Issuer Trust may have or assert
     other than the defense of payment. The following payments with
     respect to the Exchange Capital Securities, to the extent not paid
     by or on behalf of the Issuer Trust (the "Guarantee Payments"),
     will be subject to the Exchange Guarantee: (i) any accrued and
     unpaid Distributions required to be paid on such Exchange Capital
     Securities, to the extent that the Issuer Trust has funds on hand
     available therefor at such time, (ii) the Redemption Price with
     respect to any Exchange Capital Securities called for redemption,
     to the extent that the Issuer Trust has funds on hand available
     therefor at such time, and (iii) upon a voluntary or involuntary
     termination, winding up or liquidation of the Issuer Trust (unless
     the Exchange Junior Subordinated Debentures are distributed to
     holders of the Exchange Capital Securities), the lesser of (a) the
     aggregate amount of the Liquidation Amount of $1,000 per Exchange
     Capital Security plus accrued and unpaid Distributions of the
     Exchange Capital Securities and (b) the amount of assets of the
     Issuer Trust remaining available for distribution to holders of
     Exchange Capital Securities on liquidation of the Issuer Trust. The
     Company's obligation to make a Guarantee Payment may be satisfied
     by direct payment of the required amounts by the Company to the
     holders of the Exchange Capital Securities or by causing the Issuer
     Trust to pay such amounts to such holders.

          The Exchange Guarantee will be an irrevocable guarantee on a
     subordinated basis of the Issuer Trust's obligations under the
     Exchange Capital Securities, but will apply only to the extent that
     the Issuer Trust has funds sufficient to make such payments, and is
     not a guarantee of collection.

          If the Company does not make interest payments on the Exchange
     Junior Subordinated Debentures held by the Issuer Trust, the Issuer
     Trust will not be able to pay Distributions on the Exchange Capital
     Securities and will not have funds legally available therefor. The
     Exchange Guarantee will rank subordinate and junior in right of
     payment to all Senior Indebtedness of the Company. See " Status of
     the Guarantee." Because the Company is a holding company, the right
     of the Company to participate in any distribution of assets of any
     subsidiary upon such subsidiary's liquidation or reorganization or
     otherwise, is subject to the prior claims of creditors of that
     subsidiary, except to the extent the Company may itself be
     recognized as a creditor of that subsidiary. Accordingly, the
     Company's obligations under the Exchange Guarantee will be
     effectively subordinated to all existing and future liabilities of
     the Company's subsidiaries, and claimants should look only to the
     assets of the Company for payments thereunder. The payment of
     dividends by the Company's insurance company subsidiaries,
     including Hartford Steam Boiler, is limited under the insurance
     holding laws of each subsidiary's domicile. See "HSB Group, Inc."
     The Exchange Guarantee does not limit the incurrence or issuance of
     other secured or unsecured debt of the Company, including Senior
     Indebtedness, whether under the Junior Subordinated Indenture or
     any other indenture that the Company may enter into in the future
     or otherwise.

          The Company has, through the Exchange Guarantee, the Trust
     Agreement, the Junior Subordinated Debentures and the Junior
     Subordinated Indenture, taken together, fully, irrevocably and
     unconditionally guaranteed all of the Issuer Trust's obligations
     under the Exchange Capital Securities. No single document standing
     alone or operating in conjunction with fewer than all of the other
     documents constitutes such guarantee. It is only the combined
     operation of these documents that has the effect of providing a
     full, irrevocable and unconditional guarantee of the Issuer Trust's
     obligations under the Exchange Capital Securities. See
     "Relationship Among the Exchange Capital Securities, the Exchange
     Junior Subordinated Debentures and the Exchange Guarantee."

          Status of the Exchange Guarantee. The Exchange Guarantee will
     constitute an unsecured obligation of the Company and will rank
     subordinate and junior in right of payment to all Senior
     Indebtedness of the Company in the same manner as the Exchange
     Junior Subordinated Debentures.

          The Exchange Guarantee will constitute a guarantee of payment
     and not of collection (i.e., the guaranteed party may institute a
     legal proceeding directly against the Guarantor to enforce its
     rights under the Exchange Guarantee without first instituting a
     legal proceeding against any other person or entity). The Exchange
     Guarantee will be held for the benefit of the holders of the
     Exchange Capital Securities. The Exchange Guarantee will not be
     discharged except by payment of the Guarantee Payments in full to
     the extent not paid by the Issuer Trust or upon distribution to the
     holders of the Exchange Capital Securities of the Exchange Junior
     Subordinated Debentures. The Exchange Guarantee does not place a
     limitation on the amount of additional Senior Indebtedness that may
     be incurred by the Company. The Company expects from time to time
     to incur additional indebtedness constituting Senior Indebtedness.

          The obligations of the Company under the Exchange Guarantee
     will rank pari passu with the obligations of the Company under any
     similar Guarantee Agreements issued by the Company on behalf of
     holders of preferred or capital securities issued by the Issuer
     Trust.

          Amendments and Assignment. Except with respect to any changes
     which do not adversely affect the rights of holders of the Exchange
     Capital Securities in any material respect (in which case no vote
     will be required), the Exchange Guarantee may not be amended
     without the prior approval of the holders of not less than a
     majority of the aggregate Liquidation Amount of such outstanding
     Exchange Capital Securities. The manner of obtaining any such
     approval will be as set forth under "Description of the Exchange
     Capital Securities Voting Rights; Amendment of Trust Agreement."
     All guarantees and agreements contained in the Guarantee shall bind
     the successors, assigns, receivers, trustees and representatives of
     the Company and shall inure to the benefit of the holders of the
     Exchange Capital Securities then outstanding.

          Events of Default. An event of default under the Exchange
     Guarantee will occur upon the failure of the Company to perform any
     of its payment or other obligations thereunder. The holders of not
     less than a majority in aggregate Liquidation Amount of the
     Exchange Capital Securities have the right to direct the time,
     method and place of conducting any proceeding for any remedy
     available to the Guarantee Trustee in respect of the Exchange
     Guarantee or to direct the exercise of any trust or power conferred
     upon the Guarantee Trustee under the Exchange Guarantee.

          Any holder of the Exchange Capital Securities may institute a
     legal proceeding directly against the Company to enforce its rights
     under the Exchange Guarantee without first instituting a legal
     proceeding against the Issuer Trust, the Guarantee Trustee or any
     other person or entity.

          The Company, as guarantor, is required to file annually with
     the Guarantee Trustee a certificate as to whether or not the
     Company is in compliance with all the conditions and covenants
     applicable to it under the Guarantee.

          Information Concerning the Guarantee Trustee. The Guarantee
     Trustee, other than during the occurrence and continuance of a
     default by the Company in performance of the Exchange Guarantee,
     undertakes to perform only such duties as are specifically set
     forth in the Exchange Guarantee and, after default with respect to
     the Exchange Guarantee, must exercise the same degree of care and
     skill as a prudent person would exercise or use in the conduct of
     his or her own affairs. Subject to this provision, the Guarantee
     Trustee is under no obligation to exercise any of the powers vested
     in it by the Exchange Guarantee at the request of any holder of any
     Exchange Capital Securities unless it is offered reasonable
     indemnity against the costs, expenses and liabilities that might be
     incurred thereby.

          For information concerning the relationship between First
     Chicago, the Property Trustee, and the Company, see "Description of
     Exchange Junior Subordinated Debentures Information Concerning the
     Debenture Trustee."

          Termination of the Exchange Guarantee. The Exchange Guarantee
     will terminate and be of no further force and effect upon full
     payment of the Redemption Price of the Exchange Capital Securities,
     upon full payment of the amounts payable upon liquidation of the
     Issuer Trust or upon distribution of Exchange Junior Subordinated
     Debentures to the holders of the Exchange Capital Securities. The
     Exchange Guarantee will continue to be effective or will be
     reinstated, as the case may be, if at any time any holder of the
     Exchange Capital Securities must restore payment of any sums paid
     under the Exchange Capital Securities or the Exchange Guarantee.

          Governing Law. The Exchange Guarantee will be governed by and
     construed in accordance with the laws of the State of New York.


         RELATIONSHIP AMONG THE EXCHANGE CAPITAL SECURITIES, THE EXCHANGE
             JUNIOR SUBORDINATED DEBENTURES AND THE EXCHANGE GUARANTEE

     FULL AND UNCONDITIONAL GUARANTEE

          Payments of Distributions and other amounts due on the
     Exchange Capital Securities (to the extent the Issuer Trust has
     funds available for the payment of such Distributions) are
     irrevocably guaranteed by the Company as and to the extent set
     forth under "Description of Exchange Guarantee." Taken together,
     the Company's obligations under the Exchange Junior Subordinated
     Debentures, the Junior Subordinated Indenture, the Trust Agreement,
     and the Exchange Guarantee provide, in the aggregate, a full,
     irrevocable and unconditional guarantee of payments of
     distributions and other amounts due on the Exchange Capital
     Securities. No single document standing alone or operating in
     conjunction with fewer than all of the other documents constitutes
     such guarantee. It is only the combined operation of these
     documents that has the effect of providing a full, irrevocable and
     unconditional guarantee of the Issuer Trust's obligations under the
     Exchange Capital Securities. If and to the extent that the Company
     does not make payments on the Exchange Junior Subordinated
     Debentures, the Issuer Trust will not pay Distributions or other
     payments due on the Exchange Capital Securities. The Exchange
     Guarantee does not cover payment of Distributions when the Issuer
     Trust does not have sufficient funds to pay such Distributions or
     other payments. In such event, the remedy of a holder of the
     Exchange Capital Securities is to institute a legal proceeding
     directly against the Company for enforcement of payment of such
     Distributions or other payments to such holder. The obligations of
     the Company under the Exchange Guarantee are subordinate and junior
     in right of payment to all Senior Indebtedness.

     SUFFICIENCY OF PAYMENTS

          As long as payments of interest and other payments are made
     when due on the Exchange Junior Subordinated Debentures, such
     payments will be sufficient to cover Distributions and other
     payments due on the Capital Securities, primarily because (i) the
     aggregate principal amount of the Exchange Junior Subordinated
     Debentures will be equal to the sum of the aggregate stated
     Liquidation Amount of the Exchange Capital Securities and Common
     Securities, (ii) the interest rate and interest and other payment
     dates on the Exchange Junior Subordinated Debentures will match the
     Distribution rate and Distribution and other payment dates for the
     Exchange Capital Securities, (iii) the Company shall pay for all
     and any costs, expenses and liabilities of the Issuer Trust except
     the Issuer Trust's obligations to holders of its Exchange Capital
     Securities, and (iv) the Trust Agreement further provides that the
     Issuer Trust will not engage in any activity that is not consistent
     with the limited purposes of the Issuer Trust.

          Notwithstanding anything to the contrary in the Junior
     Subordinated Indenture, the Company has the right to set off any
     payment it is otherwise required to make thereunder with, and to
     the extent the Company has theretofore made or is concurrently on
     the date of such payment making, a payment under the Exchange
     Guarantee.

     ENFORCEMENT RIGHTS OF HOLDERS OF EXCHANGE CAPITAL SECURITIES

          A holder of any Exchange Capital Security may institute a
     legal proceeding directly against the Company to enforce its rights
     under the Exchange Guarantee without first instituting a legal
     proceeding against the Guarantee Trustee, the Issuer Trust or any
     other person or entity.

          A default or event of default under any Senior Indebtedness of
     the Company would not constitute a default or an Event of Default
     under the Trust Agreement. However, in the event of payment
     defaults under, or acceleration of, Senior Indebtedness of the
     Company, the subordination provisions of the Junior Subordinated
     Indenture provide that no payments may be made in respect of the
     Exchange Junior Subordinated Debentures until such Senior
     Indebtedness has been paid in full or any payment default
     thereunder has been cured or waived. Failure to make required
     payments on the Exchange Junior Subordinated Debentures would
     constitute an Event of Default.

     LIMITED PURPOSE OF ISSUER TRUST

          The Issuer Trust's Exchange Capital Securities evidence an
     undivided beneficial interest in the assets of the Issuer Trust,
     and the Issuer Trust exists for the sole purpose of issuing its
     Capital Securities and Common Securities and investing the proceeds
     thereof in the Junior Subordinated Debentures. A principal
     difference between the rights of a holder of a Capital Security and
     a holder of Junior Subordinated Debentures is that a holder of
     Junior Subordinated Debentures is entitled to receive from the
     Company the principal amount of and interest accrued on Junior
     Subordinated Debentures held, while a holder of Capital Securities
     is entitled to receive Distributions from the Issuer Trust (or from
     the Company under the Guarantee) if and to the extent the Issuer
     Trust has funds available for the payment of such Distributions.

     RIGHTS UPON TERMINATION

          Upon any voluntary or involuntary termination, winding-up or
     liquidation of the Issuer Trust involving the liquidation of the
     Junior Subordinated Debentures, after satisfaction of the
     liabilities of creditors of the Issuer Trust as required by
     applicable law, the holders of the Capital Securities will be
     entitled to receive, out of assets held by the Issuer Trust, the
     Liquidation Distribution in cash. See "Description of Exchange
     Capital Securities Liquidation Distribution Upon Termination." Upon
     any voluntary or involuntary liquidation or bankruptcy of the
     Company, the Property Trustee, as holder of the Exchange Junior
     Subordinated Debentures, would be a subordinated creditor of the
     Company, subordinated in right of payment to all Senior
     Indebtedness as set forth in the Junior Subordinated Indenture, but
     entitled to receive payment in full of principal and interest,
     before any stockholders of the Company receive payments or
     distributions. Since the Company is the guarantor under the
     Exchange Guarantee and has agreed to pay for all costs, expenses
     and liabilities of the Issuer Trust (other than the Issuer Trust's
     obligations to the holders of its Capital Securities), the
     positions of a holder of the Exchange Capital Securities and a
     holder of such Exchange Junior Subordinated Debentures relative to
     other creditors and to stockholders of the Company in the event of
     liquidation or bankruptcy of the Company are expected to be
     substantially the same.


                       CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     GENERAL

          The following is a summary of certain of the material United
     States federal income tax consequences of the exchange of Original
     Securities for Exchange Securities pursuant to the Exchange Offer.
     Unless otherwise stated, this summary deals only with Capital
     Securities held as capital assets by holders who purchased the
     Capital Securities upon original issuance. It does not deal with
     special classes of holders such as banks, thrifts, real estate
     investment trusts, regulated investment companies, insurance
     companies, dealers in securities or currencies, tax- exempt
     investors, persons that have a functional currency other than the
     U.S. Dollar or persons that will hold the Capital Securities as a
     position in a "straddle," as part of a "synthetic security" or
     "hedge," as part of a "conversion transaction" or other integrated
     investment, or as other than a capital asset. Further, it does not
     include any description of any alternative minimum tax consequences
     or the tax laws of any state or local government of any foreign
     government that may be applicable to the Capital Securities. This
     summary is based on the Internal Revenue Code of 1986, as amended
     (the "Code"), Treasury regulations thereunder and administrative
     and judicial interpretations thereof, as of the date hereof, all of
     which are subject to change, possibly on a retroactive basis.

     EXCHANGE OF CAPITAL SECURITIES FOR EXCHANGE CAPITAL SECURITIES

          The exchange of Original Securities for Exchange Securities
     pursuant to the Exchange Offer should have no federal income tax
     consequences to holders. Such exchange should not be treated as an
     "exchange" for United States federal income tax purposes because
     the Exchange Capital Securities and Exchange Junior Subordinated
     Debentures should not be considered to differ materially in kind or
     extent from the Original Capital Securities and the Original Junior
     Subordinated Debentures, respectively, and because the exchange
     will occur by operation of the terms of the Original Capital
     Securities and Original Junior Subordinated Debentures.
     Accordingly, the Exchange Junior Subordinated Debentures should
     have the same issue price as the Junior Subordinated Debentures,
     and a holder should have the same adjusted tax basis and holding
     period in the Exchange Capital Securities as the holder had in the
     Original Capital Securities immediately before the exchange.
     Moreover, a holder that acquired an interest in the Original Junior
     Subordinated Debentures with either market discount or bond premium
     will hold an interest in the Exchange Junior Subordinated
     Debentures with the same amount of market discount or bond premium
     and will be required to include such market discount in or deduct
     such bond premium from their income in the same manner as on the
     Original Junior Subordinated Debentures. Holders are urged to
     consult their tax advisors regarding the applicability of the
     market discount and bond premium rules.

     CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES 

          In connection with the issuance of the Original Junior
     Subordinated Debentures, Skadden, Arps, Slate, Meagher & Flom LLP
     (''Skadden, Arps''), special tax counsel to the Company and Issuer
     Trust, rendered its opinion generally to the effect that, under
     then current law and assuming full compliance with the terms of the
     Indenture (and certain other documents), and based on certain facts
     and assumptions contained in such opinion, the Original Junior
     Subordinated Debentures held by the Issuer Trust will be classified
     for United States federal income tax purposes as indebtedness of
     the Company.

     CLASSIFICATION OF HSB CAPITAL TRUST 

          In connection with the issuance of the Original Capital
     Securities, Skadden, Arps rendered its opinion generally to the
     effect that, under then current law and assuming full compliance
     with the terms of the Declaration and the Indenture (and certain
     other documents), and based on certain facts and assumptions
     contained in such opinion, the Issuer Trust will be classified for
     United States federal income tax purposes as a grantor trust and
     not as an association taxable as a corporation. Accordingly, for
     United States federal income tax purposes, each holder of Capital
     Securities generally will be considered the owner of an undivided
     interest in the Junior Subordinated Debentures, and each holder
     will be required to include in its gross income interest or
     original issue discount (''OID'') with respect to its allocable
     share of those Junior Subordinated Debentures.

     INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT 

          Under applicable Treasury regulations (the ''Regulations''),
     the Junior Subordinated Debentures will constitute variable rate
     debt instruments that will not be treated as issued with OID
     provided that stated interest is unconditionally payable at least
     annually. Under such Regulations, a ''remote'' contingency that
     stated interest will not be timely paid will be ignored in
     determining whether a debt instrument is issued with OID. The
     Company believes that the likelihood of its exercising its option
     to defer payments is remote. Based on the foregoing, the Company
     believes that the Junior Subordinated Debentures will not be
     considered to be issued with OID at the time of their original
     issuance and, accordingly, a holder of the Capital Securities
     should include in gross income such holder's allocable share of
     interest on the Junior Subordinated Debentures in accordance with
     such holder's method of tax accounting.

          Under the Regulations, if the Company exercised its option to
     defer any payment of interest, the Junior Subordinated Debentures
     would at that time be treated as issued with OID, and all stated
     interest on the Junior Subordinated Debentures would thereafter be
     treated as OID as long as the Junior Subordinated Debentures
     remained outstanding. In such event, all of a holder's taxable
     interest income with respect to the Junior Subordinated Debentures
     would be accounted for as OID on an economic accrual basis
     regardless of such holder's method of tax accounting, and actual
     distributions of stated interest would not be reported as taxable
     income. In general, the amount of OID that would accrue during any
     quarter would be calculated as if interest on the Junior
     Subordinated Debentures were payable at a fixed rate equal to the
     value of LIBOR plus .91% at the time when the Company first
     exercised its option to defer an interest payment, increased or
     decreased to take into account the difference, if any, between that
     rate and any actual payment of stated interest during the quarter.
     Consequently, a holder of Capital Securities would be required to
     include in gross income OID even though the Company would not make
     any actual cash payments during an Extension Period.

          The Regulations have not been addressed in any rulings or
     other interpretations by the Internal Revenue Service (the
     "IRS"), and it is possible that the IRS could take a position
     contrary to the interpretation herein.

          Because income on the Capital Securities will constitute
     interest or OID, corporate holders of Capital Securities will not
     be entitled to a dividends-received deduction with respect to any
     income recognized with respect to the Capital Securities.

     RECEIPT OF JUNIOR SUBORDINATED DEBENTURES OR CASH 

          Under certain circumstances, as described under "Description
     of the Capital Securities Liquidation Distribution Upon
     Termination," Junior Subordinated Debentures may be distributed to
     holders in exchange for the Capital Securities upon the liquidation
     of the Issuer Trust. Under current law, such a distribution, for
     United States federal income tax purposes, would be treated as a
     non-taxable event to each holder, and each holder would receive an
     aggregate tax basis in the Junior Subordinated Debentures equal to
     such holder's aggregate tax basis in its Capital Securities. A
     holder's holding period in the Junior Subordinated Debentures
     received in liquidation of the Issuer Trust would include the
     period during which the Capital Securities were held by such
     holder.

          Under certain circumstances, as described under "Description
     of the Capital Securities Redemption", the Junior Subordinated
     Debentures may be redeemed by the Company for cash and the proceeds
     of such redemption distributed by the Issuer Trust to holders in
     redemption of their Capital Securities. Under current law, such a
     redemption would, for United States federal income tax purposes,
     constitute a taxable disposition of the redeemed Capital
     Securities, and a holder would recognize gain or loss as if it sold
     such redeemed Capital Securities for cash. See "--Sales of Capital
     Securities."

     SALES OF CAPITAL SECURITIES 

          A holder that sells Capital Securities will be considered to
     have disposed of all or part of the holder's pro rata share of the
     Junior Subordinated Debentures and will recognize gain or loss
     equal to the difference between its adjusted tax basis in the
     Capital Securities and the amount realized on the sale of such
     Capital Securities. Assuming that the Company does not exercise its
     option to defer payment of interest on the Junior Subordinated
     Debentures, a holder's adjusted tax basis in the Capital Securities
     generally will be its initial purchase price. If the Junior
     Subordinated Debentures are deemed to be issued with OID as a
     result of the Company's deferral of any interest payment, a
     holder's tax basis in the Capital Securities generally will be its
     initial purchase price, increased by OID previously includible in
     such holder's gross income to the date of disposition and decreased
     by distributions or other payments received on the Capital
     Securities since and including the date of the first Extension
     Period. Such gain or loss generally will be a capital gain or loss
     (except to the extent of any accrued interest with respect to such
     holder's pro rata share of the Junior Subordinated Debentures not
     previously included in income) and generally will be a long-term
     capital gain or loss if the Capital Securities have been held for
     more than one year.

          Should the Company exercise its option to defer any payment of
     interest on the Junior Subordinated Debentures, the Capital
     Securities may trade at a price that does not accurately reflect
     the value of accrued but unpaid interest with respect to the
     underlying Junior Subordinated Debentures. In the event of such a
     deferral, a holder who disposes of its Capital Securities between
     record dates for payments of distributions thereon will be required
     to include in income as ordinary income accrued but unpaid interest
     on the Junior Subordinated Debentures to the date of disposition
     and to add such amount to its adjusted tax basis in its pro rata
     share of the underlying Junior Subordinated Debentures deemed
     disposed of. To the extent the selling price is less than the
     holder's adjusted tax basis, such holder will recognize a capital
     loss. Subject to certain limited exceptions, capital losses cannot
     be applied to offset ordinary income for United States federal
     income tax purposes.

     CONDITIONAL RIGHT TO SHORTEN MATURITY 

          Prospective investors should be aware that the Company's
     exercise of its right to shorten the maturity of the Junior
     Subordinated Debentures will be a taxable event to holders of
     Capital Securities if the Junior Subordinated Debentures are
     treated as equity for purposes of United States federal income
     taxation before the maturity is shortened. See "Description of
     Capital Securities Conditional Right to Shorten Maturity or Redeem
     upon a Tax Event," "Description of Junior Subordinated Debentures
     Conditional Right to Shorten Maturity or Redeem upon a Tax Event
     and "--Possible Tax Law Changes."

     POSSIBLE TAX LAW CHANGES 

          On February 6, 1997, as part of the fiscal budget submitted to
     Congress, the Clinton Administration proposed the Clinton Proposal
     which would, among other things, generally treat as equity, for
     federal income tax purposes, certain debt obligations, such as the
     Junior Subordinated Debentures, that were issued on or after the
     date of "first committee action". The Junior Subordinated
     Debentures were issued prior to the date of first committee action.
     The Clinton Proposal was not included in the tax legislation signed
     into law by President Clinton on August 5, 1997. There can be no
     assurance, however, that similar legislation enacted in the future
     will not adversely affect the tax treatment of the Junior
     Subordinated Debentures, which could result in the redemption of
     the Junior Subordinated Debentures by the Company and the
     distribution of the resulting cash in redemption of the Capital
     Securities or a shortening of the maturity of the Capital
     Securities. See "Description of Exchange Junior Subordinated
     Debentures Redemption" and "Description of Exchange Capital
     Securities Redemption."

     UNITED STATES ALIEN HOLDERS 

          For purposes of this discussion, a "United States Alien
     Holder" is any corporation, individual, partnership, estate or
     trust that is, as to the United States, a foreign corporation, a
     non-resident alien individual, a foreign partnership, or a non-
     resident fiduciary of a foreign estate or trust.

          Under present United States federal income tax law: (i)
     payments by the Issuer Trust or any of its paying agents to any
     holder of a Capital Security who or which is a United States Alien
     Holder will not be subject to United States federal withholding
     tax; provided, that, (a) the beneficial owner of the Capital
     Security does not actually or constructively own 10% or more of the
     total combined voting power of all classes of stock of the Company
     entitled to vote, (b) the beneficial owner of the Capital Security
     is not a controlled foreign corporation that is related to the
     Company through stock ownership, and (c) either (A) the beneficial
     owner of the Capital Security certifies to the Issuer Trust or its
     agent, under penalties of perjury, that it is not a United States
     Alien Holder and provides its name and address or (B) a securities
     clearing organization, bank or other financial institution that
     holds customers' securities in the ordinary course of its trade or
     business (a ''Financial Institution''), and holds the Capital
     Security in such capacity, certifies to the Issuer Trust or its
     agent, under penalties of perjury, that such statement has been
     received from the beneficial owner by it or by a Financial
     Institution holding such security for the beneficial owner and
     furnished the Issuer Trust or its agent with a copy thereof; and
     (ii) a United States Alien Holder of a Capital Security will not be
     subject to United States federal withholding tax on any gain
     realized upon the sale or other disposition of a Capital Security.

          Proposed Treasury regulations could affect the procedures to
     be followed by a United States Alien Holder in establishing such
     holder's status for purposes of United States federal withholding
     tax rules. The proposed regulations, if adopted in their current
     form, generally would be effective for payments made after December
     31, 1997. Prospective purchasers should consult their tax advisors
     concerning the potential adoption of such regulations and their
     effect on an investment in the Capital Securities.

     INFORMATION REPORTING TO HOLDERS 

          Generally, income on the Capital Securities will be reported
     to holders on Forms 1099, which forms should be mailed to holders
     of Capital Securities by January 31 following each calendar year.

     BACKUP WITHHOLDING 

          Payments made on, and proceeds from the sale of, the Capital
     Securities may be subject to a ''backup'' withholding tax of 31%
     unless the holder complies with certain identification
     requirements. Any withheld amounts will be allowed as a credit
     against the holder's United States federal income tax, provided the
     required information is provided to the IRS on a timely basis.


          THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH
     ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE
     APPLICABLE DEPENDING UPON A HOLDER'S PARTICULAR SITUATION. HOLDERS
     SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
     CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF
     THE CAPITAL SECURITIES AND THE EXCHANGE OF ORIGINAL CAPITAL
     SECURITIES FOR EXCHANGE CAPITAL SECURITIES PURSUANT TO THE EXCHANGE
     OFFER, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN
     AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED
     STATES FEDERAL OR OTHER TAX LAWS.



                             CERTAIN ERISA CONSIDERATIONS

          Each fiduciary of a Plan should consider the fiduciary
     standards of ERISA in the context of the Plan's particular
     circumstances before authorizing an investment in the Capital
     Securities. Accordingly, among other factors, the fiduciary should
     consider whether the investment would satisfy the prudence and
     diversification requirements of ERISA and would be consistent with
     the documents and instruments governing the Plan.

          Section 406 of ERISA and Section 4975 of the Code prohibit
     Plans, as well as individual retirement accounts and Keogh plans
     subject to Section 4975 of the Code (also "Plans"), from engaging
     in certain transactions involving "plan assets" with persons who
     are "parties in interest" under ERISA or "disqualified persons"
     under the Code ("Parties in Interest") with respect to such Plan. A
     violation of these "prohibited transaction" rules may result in an
     excise tax or other liabilities under ERISA and/or Section 4975 of
     the Code for such persons, unless exemptive relief is available
     under an applicable statutory or administrative exemption. Employee
     benefit plans that are governmental plans (as defined in Section
     3(32) of ERISA), certain church plans (as defined in Section 3(33)
     of ERISA) and foreign plans (as described in Section 4(b)(5) of
     ERISA) are not subject to the requirements of ERISA or Section 4975
     of the Code.

          Under a regulation (the "Plan Assets Regulation") issued by
     the U.S. Department of Labor (the "DOL"), the assets of the Issuer
     Trust would be deemed to be "plan assets" of a Plan for purposes of
     ERISA and Section 4975 of the Code if "plan assets" of the Plan
     were used to acquire an equity interest in the Trust and no
     exception were applicable under the Plan Assets Regulation. An
     "equity interest" is defined under the Plan Assets Regulation as
     any interest in an entity other than an instrument which is treated
     as indebtedness under applicable local law and which has no
     substantial equity features and specifically includes a beneficial
     interest in a trust.

          Pursuant to an exception contained in the Plan Assets
     Regulation, the assets of the Issuer Trust would not be deemed to
     be "plan assets" of investing Plans if, immediately after the most
     recent acquisition of any equity interest in the Trust, less than
     25% of the value of each class of equity interests in the Trust
     were held by Plans, other employee benefit plans not subject to
     ERISA or Section 4975 of the Code (such as governmental, church and
     foreign plans), and entities holding assets deemed to be "plan
     assets" of any Plan (collectively, "Benefit Plan Investors"). No
     assurance can be given by the Initial Purchasers that the value of
     the Capital Securities held by Benefit Plan Investors will be less
     than 25% of the total value of such Capital Securities at the
     completion of the initial offering or thereafter, and no monitoring
     or other measures will be taken with respect to the satisfaction of
     the conditions to this exception. All of the Common Securities will
     be purchased and held by the Company.

          Certain transactions involving the Issuer Trust could be
     deemed to constitute direct or indirect prohibited transactions
     under ERISA and Section 4975 of the Code with respect to a Plan if
     the Capital Securities were acquired with "plan assets" of such
     Plan and assets of the Issuer Trust were deemed to be "plan assets"
     of Plans investing in the Issuer Trust. For example, if the Company
     is a Party in Interest with respect to an investing Plan (either
     directly or by reason of its ownership of its subsidiaries),
     extensions of credit between the Company and the Issuer Trust (as
     represented by the Junior Subordinated Debentures and the
     Guarantee) would likely be prohibited by Section 406(a)(1)(B) of
     ERISA and Section 4975(c)(1)(B) of the Code, unless exemptive
     relief were available under an applicable administrative exemption
     (see below). In addition, if the Company were considered to be a
     fiduciary with respect to the Issuer Trust as a result of certain
     powers it holds (such as the powers to remove and replace the
     Property Trustee and the Administrators), the optional redemption
     or acceleration of the Junior Subordinated Debentures could be
     considered to be prohibited transactions under Section 406(b) of
     ERISA and Section 4975(c)(1)(E) of the Code. In order to seek to
     avoid such prohibited transactions, each investing Plan, by
     purchasing the Capital Securities, will be deemed to have directed
     the Issuer Trust to invest in the Junior Subordinated Debentures
     and to have appointed the Property Trustee and will have certain
     powers with respect to the removal and replacement of the Property
     Trustee.

          The DOL has issued five PTCEs that may provide exemptive
     relief for direct or indirect prohibited transactions resulting
     from the purchase or holding of the Capital Securities, assuming
     that assets of the Issuer Trust were deemed to be "plan assets" of
     Plans investing in the Trust (see above). Those class exemptions
     are PTCE 96-23 (for certain transactions determined by in-house
     asset managers), PTCE 95-60 (for certain transactions involving
     insurance company general accounts), PTCE 91-38 (for certain
     transactions involving bank collective investment funds), PTCE 90-1
     (for certain transactions involving insurance company separate
     accounts), and PTCE 84-14 (for certain transactions determined by
     independent qualified asset managers).

          Because the Capital Securities may be deemed to be equity
     interests in the Issuer Trust for purposes of applying ERISA and
     Section 4975 of the Code, the Capital Securities may not be
     purchased or held by any Plan, any entity whose underlying assets
     include "plan assets" by reason of any Plan's investment in the
     entity (a "Plan Asset Entity") or any person investing "plan
     assets" of any Plan, unless such purchaser or holder is eligible
     for the exemptive relief available under PTCE 96-23, 95-60, 91- 38,
     90-1 or 84-14 or another applicable exemption. Any purchaser or
     holder of the Capital Securities or any interest therein will be
     deemed to have represented by its purchase and holding thereof that
     it either (a) is not a Plan or a Plan Asset Entity and is not
     purchasing such securities on behalf of or with "plan assets" of
     any Plan or (b) is eligible for the exemptive relief available
     under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another applicable
     exemption with respect to such purchase or holding. See "Notice to
     Investors" herein.

          In order to delineate fiduciary responsibility appropriately,
     each investing Plan, by purchasing the Capital Securities, will be
     deemed to have (i) directed the Issuer Trust to invest in the
     Junior Subordinated Debentures and (ii) appointed First Chicago (an
     entity unaffiliated with and independent of the Issuer Trust) as
     Property Trustee under the Trust Agreement responsible for certain
     administrative functions with respect to the Capital Securities.
     The appointment of First Chicago as Property Trustee in the
     preceding sentence does not extend beyond the duties of First
     Chicago as Property Trustee set forth in the Trust Agreement and
     First Chicago expressly assumes no other fiduciary responsibilities
     to the Plan, including without limitation any duty with respect to
     the prudence or diversification of investments under the Plan.

          Due to the complexity of these rules and the penalties that
     may be imposed upon persons involved in non-exempt prohibited
     transactions, it is particularly important that fiduciaries or
     other persons considering purchasing the Capital Securities on
     behalf of or with "plan assets" of any Plan consult with their
     counsel regarding the potential consequences if the assets of the
     Issuer Trust were deemed to be "plan assets" and the availability
     of exemptive relief under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14
     or any other applicable exemption.

          
                          PLAN OF DISTRIBUTION

          Each broker-dealer that receives Exchange Securities for its
     own account pursuant to the Exchange Offer must acknowledge that it
     will deliver a prospectus in connection with any resale of such
     Exchange Securities. This Prospectus, as it may be amended or
     supplemented from time to time, may be used by a broker-dealer in
     connection with resales of Exchange Securities received in exchange
     for Securities where such Securities were acquired as a result of
     market-making activities or other trading activities. The Company
     has agreed that, for a period of 180 days after the Expiration
     Date, it will make this prospectus, as amended or supplemented,
     available to any broker-dealer for use in connection with any such
     resale. In addition, until , 199 , all dealers effecting
     transactions in the Exchange Securities may be required to deliver
     a prospectus.

          The Company will not receive any proceeds from any sale of
     Exchange Securities by broker-dealers. Exchange Securities received
     by broker-dealers for their own account pursuant to the Exchange
     Offer may be sold from time to time in one or more transactions in
     the over-the-counter market, in negotiated transactions, through
     the writing of options on the Exchange Securities or a combination
     of such methods of resale, at market prices prevailing at the time
     of resale, at prices related to such prevailing market prices or
     negotiated prices. Any such resale may be made directly to
     purchasers or to or through brokers or dealers who may receive
     compensation in the form of commissions or concessions from any
     such broker-dealer or the purchasers of any such Exchange
     Securities. Any broker-dealer that resells Exchange Securities that
     were received by it for its own account pursuant to the Exchange
     Offer and any broker or dealer that participates in a distribution
     of such Exchange Securities may be deemed to be an "underwriter"
     within the meaning of the Securities Act and any profit on any such
     resale of Exchange Securities and any commission or concessions
     received by any such persons may be deemed to be underwriting
     compensation under the Securities Act. The Letter of Transmittal
     states that, by acknowledging that it will deliver and by
     delivering a prospectus, a broker-dealer will not be deemed to
     admit that it is an "underwriter" within the meaning of the
     Securities Act.

          For a period of 180 days after the Expiration Date the Company
     will promptly send additional copies of this Prospectus and any
     amendment or supplement to this Prospectus to any broker- dealer
     that requests such documents in the Letter of Transmittal. The
     Company has agreed to pay all expenses incident to the Exchange
     Offer (including the expenses of one counsel for the Holders of the
     Securities) other than commissions or concessions of any brokers or
     dealers and will indemnify the Holders of the Securities (including
     any broker-dealers) against certain liabilities, including
     liabilities under the Securities Act.

                         VALIDITY OF SECURITIES

          The validity of the Exchange Capital Securities, the Exchange
     Guarantee and the Exchange Junior Subordinated Debentures will be
     passed upon for the Company by Robert C. Walker, Senior Vice
     President and General Counsel of the Company and by Skadden, Arps, 
     Slate, Meagher & Flom LLP as special counsel to the Issuer Trust. 
     Certain matters relating to United States federal income tax 
     considerations will be passed upon for the Company by Skadden, 
     Arps, Slate, Meagher & Flom LLP.

     ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          HSB Group's Articles of Incorporation provide that HSB will
     indemnify directors to the fullest extent permitted under the law.
     The Connecticut Business Corporation Act ("CBCA") permits a
     corporation to indemnify its directors against liability (including
     judgments, settlements, penalties and fines) if such individual
     acted in good faith, reasonably believed that his or her conduct
     was in the corporation's best interests and, in the case of
     criminal proceedings, had no reasonable cause to believe his or her
     conduct was unlawful. In a proceeding by or in the right of the
     corporation, the corporation may indemnify a director only for
     reasonable expenses, and may not indemnify a director who is
     adjudged liable to the corporation. Indemnification of such
     expenses is mandatory when a director is successful in the defense
     of any proceeding. The CBCA also permits a corporation to pay or
     reimburse the reasonable expenses incurred by a director who is a
     party to an action, suit or proceeding (whether civil, criminal,
     administrative or investigative) in advance of the final
     disposition of such action, suit or proceeding provided that (i)
     such director affirms in writing such director's good faith belief
     that the standard of conduct required under the statute has been
     met; (ii) such director furnishes a written undertaking to repay
     the corporation if it is ultimately determined that such standard
     has not been met; and (iii) a determination is made pursuant to the
     statute that the facts then known would not preclude
     indemnification under the statute. Provision for such advance of
     expenses in accordance with the CBCA is included in HSB Group's
     Articles of Incorporation. As permitted by the CBCA, HSB Group will
     continue to secure insurance which provides broader indemnification
     of directors than is required under the CBCA.

     ITEM 22.  UNDERTAKINGS

          Each of the undersigned Registrants hereby undertakes that,
     for purposes of determining any liability under the Securities Act
     of 1933, as amended, each filing of a Registrant's annual report
     pursuant to Section 13(a) or Section 15(d) of the Securities
     Exchange Act of 1934 (and, where applicable, each filing of an
     employee benefit plan's annual report pursuant to Section 15(d) of
     the Securities Exchange Act of 1934) that is incorporated by
     reference in this Registration Statement shall be deemed to be a
     new registration statement relating to the securities offered
     herein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of each undersigned Registrant pursuant to the
     provisions, or otherwise, each Registrant has been advised that in
     the opinion of the Securities and Exchange Commission such
     indemnification is against public policy as expressed in the Act
     and is, therefore, unenforceable. In the event that a claim for
     indemnification against such liabilities (other than the payment by
     each undersigned Registrant of expenses incurred or paid by a
     director, officer of controlling person of each Registrant in the
     successful defense of any action, suit or proceeding) is asserted
     by such director, officer or controlling person in connection with
     the securities being registered, each Registrant will, unless in
     the opinion of its counsel the matter has been settled by the
     controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Act and will be governed
     by the final adjudication of such issue.

          The undersigned Registrants hereby undertake to respond to
     requests for information that is incorporated by reference into the
     Prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within
     one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt
     means. This includes information contained in documents filed
     subsequent to the effective date of the registration statement
     through the date of responding to the request.

No. R-___                                                        $_________

      HSB Group, Inc., a Connecticut corporation (hereinafter called the
"Corporation", which term includes any successor Person under the
Indenture hereinafter referred to), for value received, hereby promises
to pay to The First National Bank of Chicago, as Property Trustee,
pursuant to the Amended and Restated Trust Agreement of HSB Capital I,
dated as of July 15, 1997, or registered assigns, the principal sum of
____________ ($________) Dollars on July 15, 2027; provided that the
Corporation may shorten the Stated Maturity of the principal of this
Security to a date not earlier than April 15, 2012, in the circumstances
described on the reverse hereof. The Corporation further promises to pay
interest on said principal sum from October 15, 1997 or from the most
recent Interest Payment Date to which interest has been paid or duly
provided for quarterly (subject to deferral as set forth herein) in
arrears on January 15, April 15, July 15, and October 15 of each year,
commencing Janu ary 15, 1998, at the variable annual rate of LIBOR plus
 .91% on the principal amount thereof, together with Additional Sums, if
any, as provided in Section 10.6 of the Indenture until the principal
hereof is paid or duly provided for or made available for payment;
provided that any overdue principal, premium or Additional Sums and any
overdue installment of interest shall bear Additional Interest at the
variable annual rate of LIBOR plus .91% (to the extent that the payment
of such interest shall be legally enforceable), compounded quarterly from
the dates such amounts are due until they are paid. The amount of
interest payable for any period will be computed on the basis of the
actual number of Days in the applicable payment period (which actual
number of days shall include the first day but exclude the last day of
such payment period) divided by 360. LIBOR shall mean the rate for
Eurodollar deposits having a three month maturity determined in
accordance with the First Supplemental Indenture hereinafter referred to.
The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular
Record Date for such interest installment, which shall be the January 1,
April 1, July 1 or October 1 (whether or not a Business Day), as the case
may be, next preceding such Interest Payment Date. Any such interest not
so punctually paid or duly provided for shall forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture.

      So long as no Event of Default has occurred and is continuing, the
Corporation shall have the right, at any time during the term of this
Security, from time to time to defer the payment of interest on this
Security for up to 20 consecutive quarterly interest payment periods with
respect to each deferral period (each an "Extension Period") at the end
of which the Corporation shall pay all interest then accrued and unpaid
(including any Additional Interest, as provided below); provided,
however, that no Extension Period shall extend beyond the Stated Maturity
of the principal of this Security, as then in effect, and no such
Extension Period may end on a date other than an Interest Payment Date.
During any such Extension Period, the Corporation shall not and shall not
permit any subsidiary of the Company to, (i) declare or pay any dividends
or distributions on, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of the Corporation's capital stock, or (ii)
make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities of the Corporation that
rank pari passu in all respects with or junior in interest to this
Security or (iii) make any guarantee payments with respect to any
guarantee by the Corporation of the debt securities of any subsidiary of
the Corporation if such guarantee ranks pari passu with or junior in
interest to this Security (other than (a) dividends or distributions in
common stock of the Corporation, (b) any declaration of a dividend in
connection with the implementation of a stockholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) payments under the
Guarantee and (d) purchases of common stock related to the issuance of
common stock or rights under any of the Corpora tion's or its
subsidiaries' benefit plans for their directors, officers or employees).
Prior to the termination of any such Extension Period, the Corporation
may further defer the payment of interest, provided that no Extension
Period shall exceed 20 consecutive quarterly interest payment periods,
extend beyond the Stated Maturity of the principal of this Security or
end on a date other than an Interest Payment Date. Upon the termination
of any such Extension Period and upon the payment of all accrued and
unpaid interest and any Additional Interest then due on any Interest
Payment Date, the Corporation may elect to begin a new Extension Period,
subject to the above conditions. No interest shall be due and payable
during an Extension Period, except at the end thereof, but each
installment of interest that would otherwise have been due and payable
during such Extension shall bear Additional Interest (to the extent that
the payment of such interest shall be legally enforceable) at the rate of
LIBOR plus .91% per annum, compounded quarterly and calculated as set
forth in the first paragraph of this Security, from the dates on which
amounts would otherwise have been due and payable until paid or made
available for payment. The Corporation shall give the Holder of this
Security and the Trustee notice of its election to begin any Extension

such purposes. Each Holder hereof, by such Holder's acceptance hereof,
waives all notice of the acceptance of the subordination provisions
contained herein and in the Indenture by each holder of Senior
Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

      Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all

Depositor, the Trustees named therein and the Holders from time to time
of the Trust Securities issued pursuant thereto, shall have the meanings
assigned to them in the Indenture or the Trust Agreement, as the case may
be.

15, 2007 and subject to the terms and conditions of Article XI of the
Indenture, redeem this Security in whole at any time or in part from time
to time, at a Redemption Price equal to 100% of the principal amount

option, at any time within 90 days of the occurrence and during the
continuation of such Tax Event redeem this Security, in whole but not

Indenture, at a Redemption Price equal to 100% of the principal amount of

Corporation may, at its option, shorten the Stated Maturity of this
Security to the minimum extent, but in no event to a date not earlier

Maturity, interest paid on this Security will be deductible for U.S.
federal income tax purposes. Upon the exercise of the right to shorten
the Stated Maturity of this Security, the Corporation will not have the
right to redeem this Security prior to the new Stated Maturity upon the

rights and obligations of the Corporation and of the Holders of the
Securities, with the consent of the Holders of not less than a majority
in principal amount of the Outstanding Securities of each series to be
affected by such supplemental indenture. The Indenture also contains
provisions permitting Holders of specified percentages in principal
amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive
compliance by the Corporation with certain provisions of the Indenture
and certain past defaults under the Indenture and their consequences. Any
such consent or waiver by the Holder of this Security shall be conclusive

exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

an Event of Default with respect to the Securities of this series at the
time Outstanding occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities of this series may declare the
principal amount of all the Outstanding Securities of this series to be
due and payable immediately, by a notice in writing to the Corporation
(and to the Trustee if given by Holders), provided that, if upon an Event
of Default, the Trustee or such Holders fail to declare the principal of
all the Outstanding Securities of this series to be immediately due and
payable, the holders of at least 25% in aggregate Liquidation Amount of
the Capital Securities then Outstanding shall have the right to make such
declaration by a notice in writing to the Corporation and the Trustee;
and upon any such declaration the principal of and the accrued interest
(including any Additional Interest) on all the Securities of this series
shall become immediately due and payable, provided that the payment of
such principal and interest (including any Additional Interest) on such
Securities shall remain subordinated to the extent provided in Article
XIII of the Indenture.

      No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay the principal
of (and premium, if any) and interest (including any Additional Interest)
on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

      As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the
Securities Register, upon surrender of this Security for registration
of transfer at the office or agency of the Corporation maintained under
Section 10.2 of the Indenture for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to

authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or trans ferees.

without coupons in denominations of $1,000 and any integral multiple of

in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the
same.

transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in
connection therewith.

      Prior to due presentment of this Security for registration of
transfer, the Corporation, the Trustee and any agent of the Corporation
or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this
Security be overdue, and neither the Corporation, the Trustee nor any
such agent shall be affected by notice to the contrary.

beneficial interest therein, the Holder of, and any Person that acquires
a beneficial interest in, this Security agree that for United States
Federal, state and local tax purposes it is intended that this Security

agreement (the "Common Securities Guarantee"), with substantially identical

of the Common Securities (as defined herein), except that if an Event of
Default (as defined in the Declaration) has occurred and is continuing, the

of holders of Exchange Capital Securities and the Exchange Capital
Securities to receive Guarantee Payments under this Exchange Guarantee
Agreement and the Exchange Guarantee, as the case may be.

         NOW, THEREFORE, in consideration of the exchange by each Holder,

Guarantee Trustee for the benefit of the Holders, and the Guarantee Trustee
shall not transfer this Exchange Guarantee Agreement to any Person except
to a Successor Guarantee Trustee on acceptance by such Successor Guarantee

right, title and interest of the Guarantee Trustee, as such, hereunder
shall automatically vest in any Successor Guarantee Trustee, upon

occurred, shall undertake to perform only such duties as are specifically
set forth in this Exchange Guarantee Agreement (including pursuant to

Guarantee Agreement against the Guarantee Trustee. If an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6),
the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Exchange Guarantee Agreement, and use the same degree of care
and skill in its exercise thereof, as a prudent person would exercise or
use under the circumstances in the conduct of his or her own affairs.

         (d) No provision of this Exchange Guarantee Agreement shall be
construed to relieve the Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act or its own wilful
misconduct, except that:

                  (i) Prior to the occurrence of any Event of Default and
         after the curing or waiving of all such Events of Default that may
         have occurred:

                           (A) the duties and obligations of the Guarantee
                  Trustee shall be determined solely by the express
                  provisions of this Exchange Guarantee Agreement
                  (including pursuant to Section 2.1), and the Guarantee
                  Trustee shall not be liable except for the performance of
                  such duties and obligations as are specifically set forth
                  in this Exchange Guarantee Agreement (including pursuant
                  to Section 2.1); and

                           (B) in the absence of bad faith on the part of
                  the Guarantee Trustee, the Guarantee Trustee may
                  conclusively rely, as to the truth of the statements and
                  the correctness of the opinions expressed therein, upon
                  any certificates or opinions furnished to the Guarantee
                  Trustee and conforming to the requirements of this
                  Exchange Guarantee Agreement; but in the case of any such
                  certificates or opinions that by any provision hereof or
                  of the Trust Indenture Act are specifically required to
                  be furnished to the Guarantee Trustee, the Guarantee
                  Trustee shall be under a duty to examine the same to
                  determine whether or not they conform to the requirements
                  of this Exchange Guarantee Agreement.

                  (ii) The Guarantee Trustee shall not be liable for any
         error of judgment made in good faith by a Responsible Officer of
         the Guarantee Trustee, unless it shall be proved that the
         Guarantee Trustee was negligent in ascertaining the pertinent
         facts upon which such judgment was made.

                  (iii) The Guarantee Trustee shall not be liable with
         respect to any action taken or omitted to be taken by it in good
         faith in accordance with the direction of the Holders of not less
         than a Majority in Liquidation Amount of the Exchange Capital
         Securities relating to the time, method and place of conducting
         any proceeding for any remedy available to the Guarantee Trustee,
         or exercising any trust or power conferred upon the Guarantee
         Trustee, under this Exchange Guarantee Agreement.

                  (iv) Subject to Sections 3.1(b) and 3.1(d), no provision
         of this Exchange Guarantee Agreement shall require the Guarantee
         Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if the
         Guarantee Trustee shall have reasonable grounds for believing that
         the repayment of such funds or liability is not reasonably assured
         to it under the terms of this Exchange Guarantee Agreement or
         adequate indemnity against such risk or liability is not
         reasonably assured to it.

         (unless other evidence is herein specifically prescribed) may, in
         the absence of bad faith on its part, request and rely upon an

         exercise any of the rights or powers vested in it by this Exchange
         Guarantee Agreement at the request or direction of any Holder

         person in the position of the Guarantee Trustee against the costs,
         expenses (including attorneys' fees and expenses) and liabilities
         that might be incurred by it in complying with such request or
         direction, including such reasonable advances as may be requested
         by the Guarantee Trustee; provided that nothing contained in this
         Section 3.2(a)(v) shall be taken to relieve the Guarantee Trustee,
         upon the occurrence of an Event of Default, of its obligation to
         exercise the rights and powers vested in it by this Exchange
         Guarantee Agreement.

         negligence on the part of any such agent or attorney appointed by
         it with due care hereunder.

                  (viii) Whenever in the administration of this Exchange
         Guarantee Agreement the Guarantee Trustee shall deem it desirable

         (b) No provision of this Exchange Guarantee Agreement shall be
deemed to impose any duty or obligation on the Guarantee Trustee to perform

         by any provision of law in regard to the compensation of a trustee
         of an express trust); and

                  (b) except as otherwise expressly provided herein, to
         reimburse the Guarantee Trustee upon request for all reasonable
         expenses, disbursements and advances incurred or made by the
         Guarantee Trustee in accordance with any provision of this
         Exchange Guarantee Agreement (including the reasonable
         compensation and the expenses and disbursements of its agents and
         counsel), except any such expense, disbursement or advance as may
         be attributable to its negligence or bad faith; and

                  (c) to the fullest extent permitted by applicable law, to
         indemnify and hold harmless (i) the Guarantee Trustee, (ii) any
         Affiliate of the Guarantee Trustee, and (iii) any officer,
         director, shareholder, employee, representative or agent of the
         Guarantee Trustee (referred to herein as an "Indemnified Person"),
         from and a any loss, damage, liability, tax, penalty, expense or
         claim of any kind or nature whatsoever incurred by such
         Indemnified Person in connection with this Exchange Guarantee
         Agreement or any act or omission performed or omitted by such
         Indemnified Person in good faith and in manner such Indemnified
         Person reasonably believed to be within the scope of authority
         conferred on such Indemnified Person by this Exchange Guarantee
         Agreement, except that no Indemnified Person shall be entitled to
         be indemnified in respect of any loss, damage or claim incurred by
         such Indemnified Person by reason of negligence or willful
         misconduct with respect to such acts or omissions.

         The Guarantee Trustee will not claim or exact any lien or charge

of this Exchange Guarantee Agreement or the resignation or removal of the
Guarantee Trustee.

                             GUARANTEE TRUSTEE

         SECTION 4.1. Guarantee Trustee; Eligibility.

         (a) There shall at all times be a Guarantee Trustee which shall:

                  (i) not be an Affiliate of the Guarantor; and

                  (ii) be a Person that is a national or state chartered
         bank and eligible pursuant to the Trust Indenture Act to act as
         such, and that has at the time of such appointment securities
         rated in one of the three highest rating categories by a
         nationally recognized statistical rating organization and a
         combined capital and surplus of at least $50,000,000, and shall be
         a corporation meeting the requirements of Section 310(a) of the
         Trust Indenture Act. If such corporation publishes reports of
         condition at least annually, pursuant to law or to the
         requirements of its supervising or examining authority, then, for
         the purposes of this Section 4.1 and to the extent permitted by
         the Trust Indenture Act, the combined capital and surplus of such
         corporation shall be deemed to be its combined capital and surplus
         as set forth in its most recent report of condition so published.

         (b) If at any time the Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section
4.2.

         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act,
the Guarantee Trustee and Guarantor shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2. Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(c), the Guarantee Trustee may be
appointed or removed at any time by the Guarantor.

         (b) Subject to Section 4.2(c), the Guarantee Trustee may resign
from office (without need for prior or subsequent accounting) by giving
written notice thereof to the Holders and the Guarantor and by appointing a
successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office
until a Successor Guarantee Trustee shall have been appointed and shall
have accepted such appointment. No removal or resignation of a Guarantee
Trustee shall be effective until a Successor Guarantee Trustee has been
appointed and has accepted such appointment by written instrument executed
by such Successor Guarantee Trustee and delivered to the Guarantor and, in
the case of any resignation, the resigning Guarantee Trustee.

         (d) If the Guarantee Trustee shall resign, be removed or become
incapable of acting as Guarantee Trustee and a replacement shall not be
appointed prior to such resignation or removal, or if a vacancy shall occur
in the office of Guarantee Trustee for any reason, and no Successor
Guarantee Trustee shall have been appointed and accepted appointment as
provided in this Section 4.2 within 60 days after delivery to the Holders
and the Guarantor of a notice of resignation, the resigning Guarantee
Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee.
Such court may thereupon, after prescribing such notice, if any, as it may
deem proper, appoint a Successor Guarantee Trustee.


                                 ARTICLE V

                                 GUARANTEE

         SECTION 5.1. Guarantee.

         The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by or on behalf of the Issuer Trust), as and when due,
regardless of any defense, right of set-off or counterclaim that the Issuer
Trust may have or assert, except the defense of payment. The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment
of the required amounts by the Guarantor to the Holders or by causing the
Issuer Trust to pay such amounts to the Holders.

         SECTION 5.2. Waiver of Notice and Demand.

         The Guarantor hereby waives notice of acceptance of this Exchange
Guarantee Agreement and of any liability to which it applies or may apply,
presentment, demand for payment, any right to require a proceeding first
against the Guarantee Trustee, the Issuer Trust or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.

         SECTION 5.3. Obligations Not Affected.

         The obligations, covenants, agreements and duties of the Guarantor
under this Exchange Guarantee Agreement shall in no way be affected or
impaired by reason of the happening from time to time of any of the
following:

                  (a) the release or waiver, by operation of law or
         otherwise (other than by Act (as defined in the Trust Agreement)
         of the Holders), of the performance or observance by the Issuer
         Trust of any express or implied agreement, covenant, term or
         condition relating to the Exchange Capital Securities to be
         performed or observed by the Issuer Trust;

                  (b) the extension of time for the payment by the Issuer
         Trust of all or any portion of the Distributions (other than an
         extension of time for payment of Distributions that results from
         the extension of any interest payment period on the Debentures as
         provided in the Indenture), Redemption Price, Liquidation
         Distribution or any other sums payable under the terms of the
         Exchange Capital Securities or the extension of time for the
         performance of any other obligation under, arising out of, or in
         connection with, the Exchange Capital Securities;

                  (c) any failure, omission, delay or lack of diligence on
         the part of the Holders to enforce, assert or exercise any right,
         privilege, power or remedy conferred on the Holders pursuant to
         the terms of the Exchange Capital Securities, or any action on the
         part of the Issuer Trust granting indulgence or extension of any
         kind;

                  (d) the voluntary or involuntary liquidation,
         dissolution, receivership, insolvency, bankruptcy, assignment for
         the benefit of creditors, reorganization, arrangement, composition
         or readjustment of debt of, or other similar proceedings
         affecting, the Issuer Trust or any of the assets of the Issuer
         Trust;

                  (e) any invalidity of, or defect or deficiency in, the
         Exchange Capital Securities;

                  (f) the settlement or compromise of any obligation
         guaranteed hereby or hereby incurred; or

                  (g) the consummation of the Exchange Offer; or

                  (h) any other circumstance whatsoever that might
         otherwise constitute a legal or equitable discharge or defense of
         a guarantor (other than payment of the underlying obligation), it
         being the intent of this Section 5.3 that the obligations of the
         Guarantor hereunder shall be absolute and unconditional under any
         and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

         SECTION 5.4. Rights of Holders.

         The Guarantor expressly acknowledges that: (i) this Exchange
Guarantee Agreement will be deposited with the Guarantee Trustee to be held
for the benefit of the Holders; (ii) the Guarantee Trustee has the right to
enforce this Exchange Guarantee Agreement on behalf of the Holders; (iii)
the Holders of a Majority in Liquidation Amount of the Exchange Capital
Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee
in respect of this Exchange Guarantee Agreement or exercising any trust or
power conferred upon the Guarantee Trustee under this Exchange Guarantee
Agreement; and (iv) any Holder may institute a legal proceeding directly
against the Guarantor to enforce its rights under this Exchange Guarantee
Agreement without first instituting a legal proceeding against the
Guarantee Trustee, the Issuer Trust or any other Person.

         SECTION 5.5. Guarantee of Payment.

         This Exchange Guarantee Agreement creates a guarantee of payment
and not of collection. This Exchange Guarantee Agreement will not be
discharged except by payment of the Guarantee Payments in full (without
duplication of amounts theretofore paid by the Issuer Trust) or upon the
distribution of Debentures to Holders as provided in the Trust Agreement.

         SECTION 5.6. Subrogation.

         The Guarantor shall be subrogated to all rights (if any) of the
Holders against the Issuer Trust in respect of any amounts paid to the
Holders by the Guarantor under this Exchange Guarantee Agreement; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any rights
which it may acquire by way of subrogation or any indemnity, reimbursement
or other agreement, in all cases as a result of payment under this Exchange
Guarantee Agreement, if, at the time of any such payment, any amounts are
due and unpaid under this Exchange Guarantee Agreement. If any amount shall
be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay
over such amount to the Holders.

         SECTION 5.7. Independent Obligations.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer Trust with respect to the
Exchange Capital Securities and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to
the terms of this Exchange Guarantee Agreement notwithstanding the
occurrence of any event referred to in subsections (a) through (g),
inclusive, of Section 5.3 hereof.


                                 ARTICLE VI

                        COVENANTS AND SUBORDINATION

         SECTION 6.1. Subordination.

         The obligations of the Guarantor under this Exchange Capital
Securities Guarantee Agreement will constitute unsecured obligations of the
Guarantor and will rank subordinate and junior in right of payment to all
Senior Indebtedness (as defined in the Indenture) of the Guarantor to the
extent and in the manner set forth in the Indenture with respect to the
Debentures, and the provisions of Article XIII of the Indenture will apply,
mutatis mutandis, to the obligations of the Guarantor hereunder. The
obligations of the Guarantor hereunder do not constitute Senior
Indebtedness (as defined in the Indenture) of the Guarantor.

         SECTION 6.2. Pari Passu Guarantees.

         The obligations of the Guarantor under this Exchange Guarantee
Agreement shall rank pari passu with the obligations of the Guarantor under
(i) any similar guarantee agreements issued by the Guarantor on behalf of
the holders of preferred or capital securities issued by any Issuer Trust
(as defined in the Indenture) including the Guarantee Agreement, dated as
of July 15, 1997 in respect of the Series A Capital Securities; (ii) the
Indenture and the Securities (as defined therein) issued thereunder; and
(iii) any other security, guarantee or other agreement or obligation that
is expressly stated to rank pari passu with the obligations of the
Guarantor under this Exchange Guarantee Agreement or with any obligation
that ranks pari passu with the obligations of the Guarantor under this
Exchange Guarantee Agreement.


                                ARTICLE VII

                                TERMINATION

         SECTION 7.1. Termination.

         This Exchange Guarantee Agreement shall terminate and be of no
further force and effect upon (i) full payment of the Redemption Price (as
defined in the Trust Agreement) of all Exchange Capital Securities, (ii)
the distribution of Debentures to the Holders in exchange for all of the
Exchange Capital Securities, or (iii) full payment of the amounts payable
in accordance with Article IX of the Trust Agreement upon liquidation of
the Issuer Trust. Notwithstanding the foregoing, this Exchange Guarantee
Agreement will continue to be effective or will be reinstated, as the case
may be, if at any time any Holder is required to repay any sums paid with
respect to Exchange Capital Securities or this Exchange Guarantee
Agreement.


                                ARTICLE VIII

                               MISCELLANEOUS

of the Holders will be required), this Exchange Guarantee Agreement may

Majority in Liquidation Amount of the Exchange Capital Securities. The

          Dear Sirs and Madams:

                    HSB Capital I, a statutory business trust
          created pursuant to a Trust Agreement, as amended and
          restated (the "Trust Agreement"), under the laws of the
          state of Delaware (the "Trust"), proposes to issue and
          sell to certain purchasers (the "Initial Purchasers"),
          upon the terms set forth in a purchase agreement, dated
          July 15, 1997 (the "Purchase Agreement"), $110,000,000
          liquidation amount of Global Floating Rate Capital
          Securities, Series A (liquidation amount $1,000 per
          Capital Security) (the "Capital Securities"). 
          Capitalized terms used but not specifically defined
          herein are defined in the Purchase Agreement.

                    The Trust exists for the sole purpose of
          issuing its trust interests and investing the proceeds
          thereof in Global Floating Rate Junior Subordinated
          Deferable Interest Debentures, Series A (the "Junior
          Subordinated Debentures") to be issued by HSB Group,
          Inc., a Connecticut corporation (the "Company").  The
          Company has, through a Guarantee Agreement, the Trust
          Agreement, the Junior Subordinated Debentures, and the
          Indenture under which the Junior Subordinated Debentures
          are issued (the "Indenture") (the "Guarantee" and,
          together with the Capital Securities and the Junior
          Subordinated Debentures, the "Securities") guaranteed
          certain obligations in respect of the Capital Securities. 
          As an inducement to the Initial Purchasers to enter into
          the Purchase Agreement and in satisfaction of a condition
          to your obligations thereunder, the Company and the Trust
          agree with you, for the benefit of the holders of the
          Capital Securities (including the Initial Purchasers)
          (the "Holders"), as follows:

                    1.   REGISTERED EXCHANGE OFFER.  The Company
          and the Trust shall use their best efforts to file with
          the Commission within 90 calendar days after the Closing
          Date a registration statement (the "Exchange Offer
          Registration Statement") on an appropriate form under the
          Securities Act with respect to a proposed offer (the
          "Registered Exchange Offer") to the Holders to issue and
          deliver to such Holders, in exchange for (a) the Capital
          Securities, a like amount of a new series of capital
          securities of the Trust (the "Exchange Capital
          Securities") with terms substantially identical to those
          of the Capital Securities (except that the Exchange
          Capital Securities will not contain terms with respect to
          transfer restrictions under the Securities Act, and will
          be entitled, to the extent applicable, to the benefits of
          trust indentures which have been qualified under the
          Trust Indenture Act), (b) the Guarantee, the Company's
          guarantee in respect of the Exchange Capital Securities
          (the "Exchange Guarantee") with terms substantially
          identical to those of the Guarantee (except that the
          Exchange Guarantee will not contain terms with respect to
          transfer restrictions under the Securities Act) and (c)
          the Junior Subordinated Debentures, a like amount of a
          new series of junior subordinated debentures (the
          "Exchange Junior Subordinated Debentures" and, together
          with the Exchange Capital Securities and the Exchange
          Guarantee, the "Exchange Securities") with terms
          substantially identical to those of the Junior
          Subordinated Debentures (except that the Exchange Junior
          Subordinated Debentures will not contain terms with
          respect to transfer restrictions under the Securities
          Act, and will be entitled, to the extent applicable, to
          the benefits of trust indentures which have been
          qualified under the Trust Indenture Act), shall use their
          best efforts to cause the Exchange Offer Registration
          Statement to become effective under the Securities Act
          within 150 calendar days of the Closing Date and shall
          keep the Exchange Offer Registration Statement effective
          for not less than 30 calendar days (or longer, if
          required by applicable law) after the date notice of the
          Exchange Offer is mailed to the Holders (such period
          being called the "Exchange Offer Registration Period"). 
          The Exchange Securities will be issued under the
          Indenture or an indenture (the "Exchange Securities
          Indenture") between the Company and the Debenture Trustee
          or such other bank or trust company reasonably
          satisfactory to you, as trustee (the "Exchange Securities
          Trustee"), such indenture to be identical in all material
          respects to the Indenture except for the transfer
          restrictions relating to the Securities (as described
          above).

                    Upon the effectiveness of the Exchange Offer
          Registration Statement, the Company and the Trust shall
          promptly commence the Registered Exchange Offer.  An
          exchange for purposes of clauses (i) and (ii) of the next
          sentence will be deemed to have been completed only if
          the Exchange Securities received by holders, other than
          holders that are unable to make the representations set
          forth in the penultimate paragraph of Section 1 or are
          referred to in clause (iv) of Section 2 hereof, are, upon
          receipt, transferable by each such holder without
          restriction under the Securities Act and without material
          restrictions under the blue sky or securities laws of a
          substantial majority of the States of the United States
          of America.  The Exchange Offer shall be deemed to have
          been completed upon the earlier to occur of (i) the
          Company and the Trust having exchanged the Exchange
          Securities for all outstanding Securities pursuant to the
          Exchange Offer and (ii) the Company having exchanged,
          pursuant to the Exchange Offer, Exchange Securities for
          all Securities that have been properly tendered and not
          withdrawn before the expiration of the Exchange Offer
          Registration Period.  The Company and the Trust
          acknowledge that, pursuant to current interpretations by
          the Commission's staff of Section 5 of the Securities
          Act, (i) each Holder that is a broker-dealer electing to
          exchange Securities, acquired for its own account as a
          result of market making activities or other trading
          activities, for Exchange Securities (an "Exchanging
          Dealer"), is required to deliver a prospectus containing
          the information set forth in Annex A hereto on the cover,
          in Annex B hereto in the "Exchange Offer Procedures"
          section and the "Purpose of the Exchange Offer" section,
          and in Annex C hereto in the "Plan of Distribution"
          section of such prospectus in connection with a sale of
          any such Exchange Securities received by such Exchanging
          Dealer pursuant to the Registered Exchange Offer and (ii)
          if any Initial Purchaser elects to sell Exchange
          Securities acquired in exchange for Securities
          constituting any portion of an unsold allotment it is
          required to deliver a prospectus, containing the
          information required by Items 507 and/or 508 of
          Regulation S-K under the Securities Act, as applicable,
          in connection with such a sale.

                    In connection with the Registered Exchange
          Offer, the Company and the Trust shall:

                    (a)  mail to each Holder a copy of the
          prospectus forming part of the Exchange Offer
          Registration Statement, together with an appropriate
          letter of transmittal and related documents;

                    (b)  keep the Registered Exchange Offer open
          for not less that 30 days after the date notice thereof
          is mailed to the Holders (or longer if required by
          applicable law);

                    (c)  utilize the services of a Depositary for
          the Registered Exchange Offer with an address in the
          Borough of Manhattan, The City of New York;

                    (d)  permit Holders to withdraw tendered
          Securities at any time prior to the close of business,
          New York time, on the last business day on which the
          Registered Exchange Offer shall remain open; and

                    (e)  otherwise comply in all respects with all
          applicable laws applicable to the Registered Exchange
          Offer.

                    As soon as practicable after the close of the
          Registered Exchange Offer, the Company and/or the Trust,
          as the case may be, shall:

                    (a)  accept for exchange all Securities
          tendered and not validly withdrawn pursuant to the
          Registered Exchange Offer;

                    (b)  deliver to the Property Trustee for
          cancellation all Capital Securities so accepted for
          exchange; and

                    (c)  cause the Property Trustee promptly to
          authenticate and deliver to each holder of Capital
          Securities, Exchange Capital Securities equal in
          liquidation amount to the Capital Securities of such
          holder so accepted for exchange.

                    The Company shall make available for a period
          of 180 days after the consummation of the Registered
          Exchange Offer, a copy of the prospectus forming part of
          the Exchange Offer Registration Statement to any
          broker-dealer for use in connection with any resale of
          any Exchange Securities.  The Company shall keep the
          Exchange Offer Registration Statement effective for a
          period (the "Resale Period") beginning when Exchange
          Securities are first issued in the Exchange Offer and
          ending upon the earlier of (i) either (a) the expiration
          of the 180th day after the Exchange Offer has been
          completed or (b) in the event the Company and the Trust
          have at any time suspended the use of the prospectus
          contained in the Exchange Offer Registration Statement
          pursuant to Section 4(b) hereof, the day beyond the 180th
          day after the Exchange Offer has been completed that
          reflects an additional period of days equal to the number
          of days during all of the periods from and including the
          dates the Company and the Trust give notice pursuant to
          Section 4(b) hereof to and including the date when
          broker-dealers receive an amended or supplemented
          prospectus necessary to permit resales of Exchange
          Securities or to and including the date on which the
          Company and the Trust give a Resumption Notice (as
          defined in Section 4(x)) or (ii) such time as such
          broker-dealers no longer own any Exchange Securities
          whose resales by them are subject to the prospectus
          delivery requirements under the Securities Act.  With
          respect to such registration statement, each
          broker-dealer that holds Exchange Securities received in
          an Exchange Offer in exchange for Securities not acquired
          by it directly from the Company shall have the benefit of
          the rights of indemnification and contribution set forth
          in Section 6 hereof in connection with resales of
          Exchange Securities during the Resale Period.

                    Each Holder participating in the Registered
          Exchange Offer shall be required to represent to the
          Company and the Trust that at the time of the
          consummation of the Registered Exchange Offer (i) any
          Exchange Securities received by such Holder will be
          acquired in the ordinary course of business, (ii) such
          Holder will have no arrangements or understanding with
          any person to participate in the distribution of the
          Securities or the Exchange Securities within the meaning
          of the Securities Act and (iii) such Holder is not an
          affiliate of the Company within the meaning of the
          Securities Act.

                    Notwithstanding any other provisions hereof,
          the Company and the Trust will ensure that (i) any
          Exchange Offer Registration Statement and any amendment
          thereto and any prospectus forming part thereof and any
          supplement thereto complies in all material respects with
          the Securities Act and the rules and regulations
          thereunder, (ii) any Exchange Offer Registration
          Statement and any amendment thereto does not, when it
          becomes effective, contain an untrue statement of a
          material fact or omit to state a material fact required
          to be stated therein or necessary to make the statements
          therein not misleading and (iii) any prospectus forming
          part of any Exchange Offer Registration Statement, and
          any supplement to such prospectus, does not include an
          untrue statement of a material fact or omit to state a
          material fact necessary in order to make the statements
          therein, in the light of the circumstances under which
          they were made, not misleading.

                    2.   SHELF REGISTRATION.  If (i) the Company
          and the Trust are not required to file the Exchange Offer
          Registration Statement or permitted to consummate the
          Exchange Offer because the Exchange Offer is not
          permitted by applicable law or Commission policy, (ii)
          for any reason the Exchange Offer Registration Statement
          is not declared effective within 150 calendar days after
          the Closing Date, (iii) the Company has received an
          opinion of counsel, rendered by a law firm having a
          recognized national tax practice, to the effect that, as
          a result of the consummation of the Exchange Offer, there
          is more than an insubstantial risk that (x) the Trust is,
          or will be, within 90 days of the date of such opinion,
          subject to United States federal income tax with respect
          to income received or accrued on the Junior Subordinated
          Debentures or Exchange Junior Subordinated Debentures,
          (y) interest payable by the Company on such Junior
          Subordinated Debentures or Exchange Junior Subordinated
          Debentures is not, or within 90 days of the date of such
          opinion, will not be, deductible by the Company, in whole
          or in part, for United States federal income tax
          purposes, or (z) the Trust is, or will be within 90 days
          of such opinion, subject to more than a de minimis amount
          of other taxes, duties or other governmental charges, or
          (iv) any holder of Transfer Restricted Securities
          notifies the Company or the Trust on or by the 20th
          business day following the consummation of the Exchange
          Offer that (A) it is prohibited by law or Commission
          policy from participating in the Exchange Offer, (B) it
          may not resell the Exchange Capital Securities, the
          Exchange Guarantees and the Exchange Junior Subordinated
          Debentures acquired by it in the Exchange Offer to the
          public without delivering a prospectus and the prospectus
          contained in the Exchange Offer Registration Statement is
          not appropriate or available for such resales or (C) it
          is a broker-dealer and owns Capital Securities acquired
          directly from the Trust or an affiliate of the Trust, or
          (v) if the Company so elects, then the following
          provisions shall apply:

                    (a)  The Company and the Trust shall use their
          best efforts as promptly as practicable to file with the
          Commission and thereafter shall use their best efforts to
          cause to be declared effective a "shelf" registration
          statement on an appropriate form under the Securities Act
          providing for the registration of, and the sale on a
          continuous or delayed basis by the holders of, all of the
          Transfer Restricted Securities, pursuant to Rule 415 or
          any similar rule that may be adopted by the Commission
          (hereafter, a "Shelf Registration Statement" and,
          together with any Exchange Offer Registration Statement,
          a "Registration Statement").

                    (b)  The Company and the Trust shall use their
          best efforts to keep the Shelf Registration Statement
          continuously effective in order to permit the prospectus
          forming part thereof to be usable by Holders for a period
          ending on the earlier of (i) (x) the second anniversary
          of the Closing Date, (y) the expiration of the period
          following the Closing Date after which Rule 144(k) under
          the Securities Act generally becomes available to
          non-affiliates of an issuer or (z) in the event the
          Company and the Trust have at any time suspended the use
          of the prospectus contained in the Shelf Registration
          Statement pursuant to Section 4(b) hereof, the date
          beyond the earlier of the periods referred to in clauses
          (x) and (y) that reflects an additional period of days
          equal to the number of days during all of the periods
          from and including the dates the Company and the Trust
          give notice of such suspension pursuant to Section 4(b)
          to and including the date when holders of Securities
          receive an amended or supplemented prospectus necessary
          to permit resales of Securities under the Shelf
          Registration Statement or to and including the date on
          which the Company and Trust give a Resumption Notice or
          (ii) such time as all of the Securities covered by the
          Shelf Registration Statement have been sold pursuant to
          the Shelf Registration Statement or pursuant to Rule 144
          (in any such case, such period being called the "Shelf
          Registration Period").  The Company and the Trust shall
          be deemed not to have used their best efforts to keep the
          Shelf Registration Statement effective during the
          requisite period if they voluntarily take any action that
          would result in Holders of Securities covered thereby not
          being able to offer and sell such Securities during that
          period, unless such action, in the opinion of the Company
          after consulting with legal counsel, is required by
          applicable law.

                    (c)  Notwithstanding any other provisions
          hereof, the Company and the Trust will ensure that (i)
          any Shelf Registration Statement and any amendment
          thereto and any prospectus forming part thereof and any
          supplement thereto complies in all material respects with
          the Securities Act and the rules and regulations
          thereunder, (ii) any Shelf Registration Statement and any
          amendment thereto does not, when it becomes effective,
          contain an untrue statement of a material fact or omit to
          state a material fact required to be stated therein or
          necessary to make the statements therein not misleading
          and (iii) any prospectus forming part of any Shelf
          Registration Statement, and any supplement to such
          prospectus does not include an untrue statement of a
          material fact or omit to state a material fact necessary
          in order to make the statements therein, in the light of
          the circumstances under which they were made, not
          misleading.

                    3.   LIQUIDATED DAMAGES.

                    (a)  The parties hereto agree that the Holders
          of Securities will suffer damages if the Company fails to
          fulfill its obligations under Section l or Section 2, as
          applicable, and that it would not be feasible to
          ascertain the extent of such damages.  Accordingly, if
          (i) the applicable Registration Statement is not filed
          with the Commission on or prior to 90 calendar days after
          the Closing Date, (ii) the Exchange Offer Registration
          Statement or, as the case may be, the Shelf Registration
          Statement, is not declared effective within 150 calendar
          days after the Closing Date, (iii) the Exchange Offer is
          not consummated on or prior to 30 business days after the
          date on which the Exchange Offer Registration Statement
          was declared effective by the Commission, or (iv) the
          Shelf Registration Statement is filed and declared
          effective within 150 calendar days after the Closing Date
          but shall thereafter cease to be effective (at any time
          that the Company is obligated to maintain the
          effectiveness thereof) without being succeeded within 30
          calendar days by an additional Registration Statement
          filed and declared effective (each such event referred to
          in clauses (i) through (iv), a "Registration Default"),
          the Company will pay to holders of Transfer Restricted
          Securities (as defined below) as liquidated damages,
          additional interest in respect of the Junior Subordinated
          Debentures, and corresponding distributions shall
          accumulate on the Liquidation Amount of Capital
          Securities, at a rate of 0.25% per annum until (i) the
          applicable Registration Statement is filed, (ii) the
          Exchange Registration Statement is declared effective and
          the Exchange Offer is consummated, (iii) the Shelf
          Registration Statement is declared effective or (iv) the
          Shelf Registration Statement again becomes effective, as
          the case may be.  Following the cure of all Registration
          Defaults, the accrual of liquidated damages will cease. 
          As used herein, "Transfer Restricted Securities" means
          each Capital Security, Guarantee and Junior Subordinated
          Debenture until (i) the date on which such securities
          have been exchanged for a freely transferable Exchange
          Capital Security, Exchange Guarantee and Exchange Junior
          Subordinated Debenture in the Exchange Offer, (ii) the
          date on which such securities have been effectively
          registered under the Securities Act and disposed of in
          accordance with the Shelf Registration Statement or (iii)
          the date on which such securities are distributed to the
          public pursuant to Rule 144 under the Securities Act or
          are salable pursuant to Rule 144(k) under the Securities
          Act.  Notwithstanding anything to the contrary in this
          Section 3(a), the Company shall not be required to pay
          liquidated damages to the holder of Transfer Restricted
          Securities if such holder: (a) failed to comply with its
          obligations to make the representations in the second to
          last paragraph of Section 1; or (b) failed to provide the
          information required to be provided by it, if any,
          pursuant to Section 4(n).

                    (b)  The Company and the Trust shall notify the
          Property Trustee under the Trust Agreement immediately
          upon the happening of each and every Registration
          Default.  The Company shall pay the liquidated damages
          due on the Transfer Restricted Securities by depositing
          with the Property Trustee (which may not be the Company
          for these purposes), in trust, for the benefit of the
          Holders thereof, prior to 10:00 a.m. New York City time
          on the next date specified by the Trust Agreement and the
          Capital Securities for the payment of cash distributions
          in respect of the Capital Securities, sums sufficient to
          pay the liquidated damages then due.  The liquidated
          damages due shall be payable on each distribution payment
          date specified by the Trust Agreement and the Capital
          Securities to the record holder entitled to receive this
          distribution payment to be made on such date.  Each
          obligation to pay liquidated damages shall be deemed to
          accrue from and including the applicable Registration
          Default.

                    (c)  The parties hereto agree that the
          liquidated damages provided for in this Section 3
          constitute a reasonable estimate of and are intended to
          constitute the sole damages that will be suffered by
          holders of Transfer Restricted Securities by reason of
          the failure of (i) the Shelf Registration Statement or
          the Exchange Offer Registration Statement to be filed,
          (ii) the Shelf Registration Statement to be declared
          effective or to remain effective, or (iii) the Exchange
          Offer Registration Statement to be declared effective and
          the Exchange Offer to be consummated, to the extent
          required by this Agreement.

                    4.   REGISTRATION PROCEDURES. In connection
          with any Registration Statement, the following provisions
          shall apply:

                    (a)  The Company and the Trust shall (i)
          furnish to you, prior to the filing thereof with the
          Commission, a copy of the Registration Statement and each
          amendment thereof and each supplement, if any, to the
          prospectus included therein and, in the event that any of
          the Initial Purchasers (with respect to any portion of an
          unsold allotment from the original offering) are
          participating in the Registered Exchange Offer or the
          Shelf Registration, shall use reasonable efforts to
          reflect in each such document, when so filed with the
          Commission, such comments as you reasonably may propose;
          (ii) with respect to an Exchange Offer Registration
          Statement, include the information set forth in Annex A
          hereto on the cover, in Annex B hereto in the "Exchange
          Offer Procedures" section and the "Purpose of the
          Exchange Offer" section and in Annex C hereto in the
          "Plan of Distribution" section of the prospectus forming
          a part of the Exchange Offer Registration Statement, and
          include the information set forth in Annex D hereto in
          the Letter of Transmittal delivered pursuant to the
          Registered Exchange Offer; and (iii) if requested by any
          Initial Purchaser, include the information required by
          Items 507 or 508 of Regulation S-K under the Securities
          Act, as applicable, in the prospectus forming a part of
          the Exchange Offer Registration Statement.

                    (b)  The Company and the Trust shall advise you
          and, in the case of a Shelf Registration Statement, the
          Holders (if applicable), and, if requested by you or any
          such Holder, confirm such advice in writing (which advice
          pursuant to clauses (ii)-(v) hereof shall be accompanied
          by an instruction to suspend the use of the prospectus
          until the requisite changes have been made):

                         (i)  when the Registration Statement and
          any amendment thereto has been filed with the Commission
          and when the Registration Statement or any post-effective
          amendment thereto has become effective;

                         (ii)  of any comments by the Commission
          and by the Blue Sky or securities commissioner or
          regulator of any state with respect thereto or of any
          request by the Commission for amendments or supplements

          may reasonably request for delivery by (i) such

          any such Holder reasonably requests in writing and do any
          and all other acts or things necessary or advisable to
          enable the offer and sale in such jurisdictions of the
          Securities or Exchange Securities covered by such
          Registration Statement; provided, however, that the
          Company and the Trust (or any subsidiary or affiliate of
          the Company) will not be required to qualify generally to
          do business in any jurisdiction where they are not then
          so qualified or to take any action which would subject
          them to general service of process or to taxation in any
          such jurisdiction where they are not then so subject.

                    (i)  The Company and the Trust will cooperate
          with the Holders of Securities to facilitate the timely
          preparation and delivery of certificates representing

          any Registration Statement free of any restrictive
          legends and in such denominations and registered in such
          names as Holders may request in writing prior to delivery
          of Securities or Exchange Securities pursuant to such
          Registration Statement.

                    (j)  Upon the occurrence of any event
          contemplated by paragraphs (b)(ii) through (v) above
          during the period for which the Company and the Trust are
          required to maintain an effective Registration Statement,
          the Company and the Trust will promptly prepare a
          post-effective amendment to the Registration Statement or
          a supplement to the related prospectus or file any other
          required document so that, as so amended or supplemented,
          the prospectus will not include an untrue statement of a
          material fact or omit to state any material fact required
          to be stated therein or necessary to make the statements
          therein, in the light of the circumstances under which
          they were made, not misleading.

                    (k)  Not later than the effective date of the
          applicable Registration Statement, the Company and the
          Trust will provide a CUSIP number for the Securities or
          Exchange Securities, as the case may be, and provide the
          applicable trustee with printed certificates for the
          Securities or Exchange Securities, as the case may be, in
          a form eligible for deposit with The Depository Trust
          Company.

                    (l)  The Company will comply with all
          applicable rules and regulations of the Commission and

          beginning at the end of the fiscal quarter in which the
          applicable Registration Statement first became effective
          under the Securities Act, an earnings statement (which
          need not be audited) satisfying the provisions of Section
          ll(a) of the Securities Act.

                    (m)  The Company and the Trust will cause the
          Trust Agreement and the Indenture or the Exchange
          Securities Indenture, as the case may be, to be qualified
          under the Trust Indenture Act as required by applicable
          law in a timely manner.

                    (n)  The Company and the Trust may require each
          Holder of Securities to be sold pursuant to any Shelf
          Registration Statement to furnish to the Company such
          information regarding the Holder and the distribution of
          such Securities as the Company may from time to time
          reasonably request in writing for inclusion in such
          Registration Statement, but only to the extent that such
          information is required in order to comply with the
          Securities Act or the Rules of the NASD, and the Company
          may exclude from such registration the Securities of any
          Holder that unreasonably fails to furnish such
          information within a reasonable time after receiving such
          request.

          registration, and each person who participates as an
          underwriter in any offering or sale of such Securities
          and each person who controls any such person against any
          losses, claims, damages or liabilities, joint or several,
          to which such holder or underwriter may become subject
          under the Securities Act, the Exchange Act or other
          federal or state statutory law or regulation, at common
          law or otherwise, insofar as such losses, claims, damages
          or liabilities (or actions in respect thereof) arise out
          of or are based upon an untrue statement or alleged
          untrue statement of a material fact contained in any
          registration statement under which such Securities were
          registered under the Securities Act, or any preliminary,
          final or summary prospectus contained therein or
          furnished by the Company or the Trust to any such holder
          or underwriter, or any amendment or supplement thereto,
          or arise out of or are based upon the omission or alleged
          omission to state therein a material fact required to be
          stated therein or necessary to make the statements
          therein not misleading and each of the Company and the
          Trust shall, and it hereby agrees jointly and severally
          to, reimburse each such holder or underwriter for any
          legal or other expenses reasonably incurred by them in
          connection with investigating or defending any such loss,
          claim, damage, liability or action; provided, however,
          that the Company and the Trust shall not be liable to any
          such person in any such case to the extent that any such
          loss, claim, damage or liability arises out of or is
          based upon an untrue statement or alleged untrue
          statement or omission or alleged omission made in such
          registration statement, or preliminary, final or summary
          prospectus, or amendment or supplement thereto, in
          reliance upon and in conformity with written information
          furnished to the Company and the Trust by holders of
          Securities expressly for use therein.  This indemnity
          agreement will be in addition to any liability which the
          Company or the Trust may otherwise have.

                    (b)  The Company and the Trust may require, as
          a condition to including any Securities in any
          registration statement filed pursuant to Section 1 or 2
          hereof or to entering into any underwriting agreement
          with respect thereto, that the Company and the Trust
          shall have received an undertaking reasonably
          satisfactory to it from the holder of such Securities and
          from each underwriter named in any such underwriting
          agreement, severally and not jointly, to indemnify and
          hold harmless the Company and the Trust, each of the
          Company's directors, and each person who controls the
          Company or the Trust within the meaning of either the
          Securities Act or the Exchange Act, to the same extent as
          the foregoing indemnity from the Company and the Trust,
          but only with reference to written information furnished
          to the Company and the Trust by or on behalf of such
          person specifically for use in any registration
          statement, or any preliminary or final or summary
          prospectus contained therein or any amendment or
          supplement thereto.  This indemnity agreement will be in
          addition to any liability which any such person may
          otherwise have.

                    (c)  Promptly after receipt by an indemnified
          party under Section 6(a) or (b) of notice of the
          commencement of any action, such indemnified party will,
          if a claim in respect thereof is to be made against the
          indemnifying party under such subsection, notify the
          indemnifying party in writing of the commencement
          thereof; provided, however, that failure to so notify an
          indemnifying party shall not relieve such indemnifying
          party from any obligation that it may have pursuant to
          this Section except to the extent it has been materially
          prejudiced by such failure; provided further, however,
          that the failure to notify the indemnifying party shall
          not relieve it from any liability that it may have to an
          indemnified party otherwise than on account of this
          Section.  If any such claim or action shall be brought
          against an indemnified party, and the indemnified party
          notifies the indemnifying party thereof, the indemnifying
          party shall be entitled to participate therein and, to
          the extent that it may elect by written notice delivered
          to the indemnified party promptly after receiving the
          aforesaid notice from such indemnified party, jointly
          with any other similarly notified indemnifying party, to
          assume the defense thereof with counsel satisfactory to
          the indemnified party, provided that, if the defendants
          in any such action include both the indemnified party and
          the indemnifying party and the indemnified party shall
          have reasonably concluded that there may be legal
          defenses available to it and/or other indemnified parties
          which are different from or additional to those available
          to the indemnifying party, the indemnified party or
          parties shall have the right to select separate counsel
          to assert such legal defenses and to otherwise
          participate in the defense of such action on behalf of
          such indemnified party or parties.  Upon receipt of
          notice from the indemnifying party to the indemnified
          party of its election to assume the defense of such claim
          or action and approval by the indemnified party of
          counsel, the indemnifying party shall not be liable to
          the indemnified party under this Section 6 for any legal
          or other expenses subsequently incurred by the
          indemnified party in connection with the defense thereof
          other than reasonable costs of investigation; provided,
          however, that an indemnified party will have the right to
          employ its own counsel in any such action, but the fees,
          expenses and other charges of such counsel will be at the
          expense of such indemnified party unless (1) the
          employment of counsel by the indemnified party has been
          authorized in writing by the indemnifying party, (2) the
          indemnified party shall have employed separate counsel in
          connection with the assertion of legal defenses in
          accordance with the proviso to the next preceding
          sentence, (3) a conflict or potential conflict exists
          (based on advice of counsel to the indemnified party)
          between the indemnified party and indemnifying party (in
          which case the indemnifying party will not have the right
          to direct the defense of such action on behalf of the
          indemnified party) or (4) the indemnifying party has not
          in fact employed counsel satisfactory to the indemnified
          party to assume the defense of such action within a
          reasonable time after receiving notice of the
          commencement of the action, in each of which cases the
          reasonable fees, disbursements and other charges of
          counsel will be at the expense of the indemnifying party
          or parties.  It is understood that the indemnifying party
          or parties shall not, in connection with any proceeding
          or related proceedings in the same jurisdiction, be
          liable for the reasonable fees, disbursements and other
          charges of more than one separate firm of attorneys (in
          addition to any local counsel) at any one time for all
          such indemnified party or parties.  Each indemnified
          party shall use all reasonable efforts to cooperate with
          the indemnifying party in the defense of any such action
          or claim.  No indemnifying party shall be liable for any
          settlement of any such action effected without its
          written consent, but if settled with its written consent
          or if there be a final judgment for the plaintiff in any
          such action, the indemnifying party agrees to indemnify
          and hold harmless any indemnified party from and against
          any loss or liability by reason of such settlement or
          judgment.  No indemnifying party shall, without the prior
          written consent of the indemnified party, effect any
          settlement of any pending or threatened proceeding in
          respect of which any indemnified party is or could have
          been a party and indemnity could have been sought
          hereunder by such indemnified party, unless such
          settlement includes an unconditional release of such
          indemnified party from all liability on claims that are
          the subject matter of such proceeding.

                    (d)  Each party hereto agrees that, if for any
          reason the indemnification provisions contemplated by
          Section 6(a) or Section 6(b) are unavailable to or
          insufficient to hold harmless an indemnified party in
          respect of any losses, claims, damages or liabilities (or
          actions in respect thereof) referred to therein (other
          than by reason of the exceptions to the indemnification
          obligations set forth in such Sections), then each
          applicable indemnifying party, in lieu of indemnifying
          such indemnified party, shall contribute to the amount
          paid or payable by such indemnified party as a result of
          such losses, claims, damages or liabilities (or actions
          in respect thereof) in such proportion as is appropriate
          to reflect the relative fault of the indemnifying party
          and indemnified party in connection with the statements
          or omissions that resulted in such losses, claims,
          damages or liabilities (or actions in respect thereof) as
          well as any other relevant equitable considerations.  The
          relative fault of such indemnifying party and indemnified
          party shall be determined by reference to, among other
          things, whether the untrue or alleged untrue statement of
          a material fact or omission or alleged omission to state
          a material fact relates to information supplied by such
          indemnifying party or indemnified party, and the parties'
          relative intent, knowledge, access to information and
          opportunity to correct or prevent such statement or
          omission.  The amount paid or payable by an indemnified
          party as a result of the losses, claims, damages, or
          liabilities (or actions in respect thereof) referred to
          above shall be deemed to include any legal or other fees
          or expenses reasonably incurred by such indemnified party
          in connection with investigating or defending any such
          action or claim.

                    The parties hereto agree that it would not be
          just and equitable if contribution pursuant to this
          Section 6(d) were determined by pro rata allocation (even
          if the holders or any agents or underwriters or all of
          them were treated as one entity for such purpose) or by
          any other method of allocation that does not take into
          account the equitable considerations referred to in the
          immediately preceding paragraph.  Notwithstanding the
          provisions of this Section, an indemnifying party that is
          a holder of Transfer Restricted Securities or Exchange
          Securities shall not be required to contribute any amount
          in excess of the amount by which the dollar amount of the
          proceeds received by such holder from the sale of any
          Securities (after deducting any fees, discounts and
          commissions applicable thereto) exceeds the amount of any
          damages that such holder has otherwise been required to
          pay by reason of such untrue or alleged untrue statement
          or omission or alleged omission, and no underwriter shall
          be required to contribute any amount in excess of the
          amount by which the total price at which the Securities
          underwritten by it and distributed to the public were
          offered to the public exceeds the amount of any damages
          which such underwriter has otherwise been required to pay
          by reason of such untrue or alleged untrue statement or
          omission or alleged omission.  No person guilty of
          fraudulent misrepresentation (within the meaning of
          Section ll(f) of the Securities Act) shall be entitled to
          any contribution from any person who was not guilty of
          such fraudulent misrepresentation.  The holders' and any
          underwriters' obligations in this Section 6(d) to
          contribute shall be several in proportion to the
          principal amount of Securities registered or
          underwritten, as the case may be, by them and not joint.

                    7.   RULES 144 AND 144A.  The Company shall use
          its best efforts to file the reports required to be filed
          by it under the Securities Act and the Exchange Act in a
          timely manner and, if at any time the Company is not
          required to file such reports, it will, upon the written
          request of any holder of Transfer Restricted Securities,
          make publicly available other information so long as
          necessary to permit sales of such holder's securities
          pursuant to Rules 144 and 144A.  The Company covenants
          that it will take such further action as any holder of
          Transfer Restricted Securities may reasonably request,
          all to the extent required from time to time to enable
          such holder to sell Transfer Restricted Securities
          without registration under the Securities Act within the
          limitation of the exemptions provided by Rules 144 and
          144A (including, without limitation, the requirements of
          Rule 144A(d)(4)).  Upon the written request of any holder
          of Transfer Restricted Securities, the Company shall
          deliver to such holder a written statement as to whether
          it has complied with such requirements.  Notwithstanding
          the foregoing, nothing in this Section 7 shall be deemed
          to require the Company or the Trust to register any of
          its securities pursuant to the Exchange Act.

                    8.   UNDERWRITTEN REGISTRATIONS.  If any of the
          Transfer Restricted Securities covered by any Shelf
          Registration Statement are to be sold in an underwritten
          offering, the investment banker or investment bankers and
          manager or managers that will administer the offering
          will be selected by the holders of a majority in
          aggregate liquidation amount of Capital Securities to be
          included in such offering, subject to the consent of the
          Company (which shall not be unreasonably withheld or
          delayed).  The Holders shall be responsible for all
          underwriting commissions and discounts.

                    No person may participate in any underwritten
          registration hereunder unless such person (i) agrees to
          sell such person's Transfer Restricted Securities on the
          basis provided in any underwriting arrangements approved
          by the persons entitled hereunder to approve such
          arrangements and (ii) completes and executes all
          questionnaires, powers of attorney, indemnities,
          underwriting agreements and other documents reasonably
          required under the terms of such underwriting
          arrangements.

                    9.   MISCELLANEOUS.

                    (a)  AMENDMENTS AND WAIVERS.  The provisions of
          this Agreement may not be amended, modified or
          supplemented, and waivers or consents to departures from
          the provisions hereof may not be given, unless the
          Company and the Trust have obtained the written consent
          of Holders of a majority in aggregate liquidation amount
          of the Capital Securities and the Exchange Capital
          Securities, taken as a single class.  Notwithstanding the
          foregoing, a waiver or consent to depart from the
          provisions hereof with respect to a matter that relates
          exclusively to the rights of the Holders of Securities
          whose Securities or Exchange Securities are being sold
          pursuant to a Registration Statement and that does not
          directly or indirectly affect the rights of other Holders
          may be given by Holders of a majority in aggregate
          liquidation amount of the Capital Securities or Exchange
          Capital Securities being sold by such Holders pursuant to
          such Registration Statement.

                    (b)  NOTICES.  All notices and other
          communications provided for or permitted hereunder shall
          be made in writing by hand-delivery, first-class mail,
          telecopier, or air courier guaranteeing overnight
          delivery:

                    (1)  if to a Holder, at the most current
          address given by such Holder to the Trust in accordance
          with the provisions of this Section 9(b), which address
          initially is, with respect to each Holder, the address of
          such Holder maintained by the Trustee under the Trust
          Agreement;

                    (2)  if to you, initially at the respective
          addresses set forth in the Purchase Agreement; and

                    (3)  if to the Company or the Trust, initially
          at the address set forth in the Purchase Agreement.

                    All such notices and communications shall be
          deemed to have been duly given: when delivered by hand,
          if personally delivered; one business day after being
          delivered to a next-day air courier; five business days
          after being deposited in the mail; when answered back, if
          faxed; and when receipt is acknowledged by the
          recipient's telecopier machine, if telecopied.

                    (c)  SUCCESSORS AND ASSIGNS.  All the terms and
          provisions of this Registration Rights Agreement shall be
          binding upon, shall inure to the benefit of and shall be
          enforceable by the respective successors and assigns of
          the parties hereto.  In the event that any transferee of
          any holder of Securities shall, in any manner, whether by
          gift, bequest, purchase, operation of law or otherwise
          acquire Transfer Restricted Securities, such transferee
          shall, without any further writing or action of any kind,
          be deemed a party hereto for all purposes and such
          Securities shall be held subject to all of the terms of
          this Registration Rights Agreement, and by taking and
          holding such Securities such transferee shall be entitled
          to receive the benefits of, and be conclusively deemed to
          have agreed to be bound by and to perform, all of the
          applicable terms and provisions of this Registration
          Rights Agreement.

                    (d)  COUNTERPARTS.  This Agreement may be
          executed in any number of counterparts (which may be
          delivered in original form or by telecopies) and by the
          parties hereto in separate counterparts, each of which
          when so executed shall be deemed to be an original and
          all of which taken together shall constitute one and the
          same agreement.

                    (e)  HEADINGS.  The headings in this Agreement
          are for convenience of reference only and shall not limit
          or otherwise affect the meaning hereof. 

                    (f)  GOVERNING LAW; SUBMISSION TO JURISDICTION;
          WAIVER OF JURY TRIAL.

                    THIS AGREEMENT SHALL BE GOVERNED BY AND
          CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
          YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN
          THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
          CONFLICTS OF LAW.  THE COMPANY AND THE TRUST HEREBY
          IRREVOCABLY SUBMIT TO THE JURISDICTION OF ANY NEW YORK
          STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE
          CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE
          BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK IN RESPECT
          OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR
          RELATING TO THIS AGREEMENT, AND IRREVOCABLY ACCEPT FOR
          ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND
          UNCONDITIONALLY, JURISDICTION OF THE AFORESAID COURTS. 
          THE COMPANY AND THE TRUST IRREVOCABLY WAIVE, TO THE
          FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE
          LAW, TRIAL BY JURY AND ANY OBJECTION THAT THEY MAY NOW OR
          HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH
          SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT AND
          ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING
          BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN
          INCONVENIENT FORUM.  NOTHING HEREIN SHALL AFFECT THE
          RIGHT OF ANY HOLDER OF A TRANSFER RESTRICTED SECURITY TO
          SERVE PROCESS IN ANY MANNER PERMITTED BY LAW OR TO
          COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST
          THE COMPANY IN ANY OTHER JURISDICTION.

                    (g)  REMEDIES.  In the event of a breach by the
          Company, the Trust or a holder of Transfer Restricted
          Securities, of any of their obligations under this
          Agreement, each holder of Transfer Restricted Securities
          or the Company or the Trust, as the case may be, in
          addition to being entitled to exercise all rights granted
          by law, including recovery of damages (other than the
          recovery of damages for a breach by the Company or the
          Trust of their obligations under Sections 1 and 2 hereof
          for which liquidated damages have been paid pursuant to
          Section 3 hereof), will be entitled to specific
          performance of its rights under this Agreement.  The
          Company, the Trust and each holder of Transfer Restricted
          Securities agree that, except for such liquidated
          damages, when payable monetary damages would not be
          adequate compensation for any loss incurred by reason of
          a breach by it of any of the provisions of this Agreement
          and hereby further agree that, in the event of any action
          for specific performance in respect of such breach, it
          shall waive the defense that a remedy at law would be
          adequate.

                    (h)  NO INCONSISTENT AGREEMENTS.  The Company
          and the Trust have not, nor shall they on or after the
          date of this Agreement, enter into any agreement that is
          inconsistent with the rights granted to the holders of
          Transfer Restricted Securities in this Agreement or
          otherwise conflicts with the provisions hereof.  The
          Company and the Trust have not previously entered into
          any agreement which remains in effect granting any
          registration rights with respect to any capital
          securities to any person.  Without limiting the
          generality of the foregoing, without the written consent
          of the holders of a majority in aggregate principal
          amount of the then outstanding Transfer Restricted
          Securities, the Company and the Trust shall not grant to
          any person the right to request the Company to register
          any capital securities of the Company or the Trust under
          the Securities Act unless the rights so granted are
          subject in all respects to the prior rights of the
          holders of Transfer Restricted Securities set forth
          herein, and are not otherwise in conflict or inconsistent
          with the provisions of the Agreement.

                    (i)  NO PIGGYBACK ON REGISTRATIONS.  Neither
          the Company nor any of its securityholders (other than
          the holders of Transfer Restricted Securities in such
          capacity) shall have the right to include any securities
          of the Company in any Shelf Registration or Exchange
          Offer other than Transfer Restricted Securities.

                    (j)  SEVERABILITY.  The remedies provided
          herein are cumulative and not exclusive of any remedies
          provided by law.  If any term, provision, covenant or
          restriction of this Agreement is held by a court of
          competent jurisdiction to be invalid, illegal, void or
          unenforceable, the remainder of the terms, provisions,
          covenants and restrictions set forth herein shall remain
          in full force and effect and shall in no way be affected,
          impaired or invalidated, and the parties hereto shall use
          their reasonable efforts to find and employ an
          alternative means to achieve the same or substantially
          the same result as that contemplated by such term,
          provision, covenant or restriction.  It is hereby
          stipulated and declared to be the intention of the
          parties that they would have executed the remaining
          terms, provisions, covenants and restrictions without
          including any of such that may be hereafter declared
          invalid, illegal, void or unenforceable.

                    (k)  SURVIVAL.  The respective indemnities,
          agreements, representations, warranties and each other
          provision set forth in this Registration Rights Agreement
          or made pursuant hereto shall remain in full force and
          effect regardless of any investigation (or statement as
          to the results thereof) made by or on behalf of any
          holder of Securities, any director, officer or partner of
          such holder, any agent or underwriter or any director,
          officer or partner thereof, or any controlling person of
          any of the foregoing, and shall survive delivery of and
          payment for the Securities pursuant to the Purchase
          Agreement and the transfer and registration of Securities
          by such holder and the consummation of an Exchange Offer.

                    (l)  INSPECTION.  For so long as this
          Registration Rights Agreement shall be in effect, this
          Registration Rights Agreement and a complete list of the
          names and addresses of all the holders of Securities
          shall be made available, upon reasonable prior notice to
          the Company, the Property Trustee or the Trustee under
          the Indenture, as applicable, for inspection and copying
          on any business day by any holder of Securities for
          proper purposes only (which shall include any purpose
          related to the rights of the holders of Securities under
          the Securities, the Indenture and this Agreement) at the
          offices of the Company at the address thereof referenced
          in Section 9(b) above, at the office of the Property
          Trustee or at the office of the Trustee under the
          Indenture.

                    Please confirm that the foregoing correctly
          sets forth the agreement between the Company and you.

                              Very truly yours,

          On behalf of each of the Initial Purchasers



                                   ANNEX A

                    Each broker-dealer that receives Exchange
          Securities for its own account pursuant to the Exchange
          Offer must acknowledge that it will deliver a prospectus
          in connection with any resale of such Exchange
          Securities.  The Letter of Transmittal states that by so
          acknowledging and by delivering a prospectus, a
          broker-dealer will not be deemed to admit that it is an
          "underwriter" within the meaning of the Securities Act. 
          This Prospectus, as it may be amended or supplemented
          from time to time, may be used by a broker-dealer in
          connection with resales of Exchange Securities received
          in exchange for Securities where such Securities were
          acquired by such broker-dealer as a result of
          marketmaking activities or other trading activities.  The
          Company has agreed that, for a period of 180 days after
          the Expiration Date (as defined herein), it will make
          this Prospectus available to any broker-dealer for use in
          connection with any such resale.  See "Plan of
          Distribution."



                                   ANNEX B

                    Each broker-dealer that receives Exchange
          Securities for its own account in exchange for
          Securities, where such Securities were acquired by such
          broker-dealer as a result of market-making activities or
          other trading activities, must acknowledge that it will
          deliver a prospectus in connection with any resale of
          such Exchange Securities.  See "Plan of Distribution."



                                   ANNEX C

                             PLAN OF DISTRIBUTION

                    Each broker-dealer that receives Exchange
          Securities for its own account pursuant to the Exchange
          Offer must acknowledge that it will deliver a prospectus
          in connection with any resale of such Exchange
          Securities.  This Prospectus, as it may be amended or
          supplemented from time to time, may be used by a
          broker-dealer in connection with resales of Exchange
          Securities received in exchange for Securities where such
          Securities were acquired as a result of market-making
          activities or other trading activities.  The Company has
          agreed that, for a period of 180 days after the
          Expiration Date, it will make this prospectus, as amended
          or supplemented, available to any broker-dealer for use
          in connection with any such resale.  In addition, until
                          , 199   , all dealers effecting
          transactions in the Exchange Securities may be required
          to deliver a prospectus./*/

                    The Company will not receive any proceeds from
          any sale of Exchange Securities by broker-dealers. 
          Exchange Securities received by broker-dealers for their
          own account pursuant to the Exchange Offer may be sold
          from time to time in one or more transactions in the
          over-the-counter market, in negotiated transactions,
          through the writing of options on the Exchange Securities
          or a combination of such methods of resale, at market
          prices prevailing at the time of resale, at prices
          related to such prevailing market prices or negotiated
          prices.  Any such resale may be made directly to
          purchasers or to or through brokers or dealers who may
          receive compensation in the form of commissions or
          concessions from any such broker-dealer or the purchasers
          of any such Exchange Securities.  Any broker-dealer that
          resells Exchange Securities that were received by it for
          its own account pursuant to the Exchange Offer and any
          broker or dealer that participates in a distribution of
          such Exchange Securities may be deemed to be an
          "underwriter" within the meaning of the Securities Act
          and any profit on any such resale of Exchange Securities
          and any commission or concessions received by any such
          persons may be deemed to be underwriting compensation
          under the Securities Act.  The Letter of Transmittal
          states that, by acknowledging that it will deliver and by
          delivering a prospectus, a broker-dealer will not be
          deemed to admit that it is an "underwriter" within the
          meaning of the Securities Act.

                    For a period of 180 days after the Expiration
          Date the Company will promptly send additional copies of

          __________________   
          /*/  In addition,  the legend required by  Item 502(e) of
               Regulation S-K will appear on the back cover page of
               the Exchange Offer prospectus.


          this Prospectus and any amendment or supplement to this
          Prospectus to any broker-dealer that requests such
          documents in the Letter of Transmittal.  The Company has
          agreed to pay all expenses incident to the Exchange Offer
          (including the expenses of one counsel for the Holders of
          the Securities) other than commissions or concessions of
          any brokers or dealers and will indemnify the Holders of
          the Securities (including any broker-dealers) against
          certain liabilities, including liabilities under the
          Securities Act.



                                   ANNEX D

     [ ]  check here if you are a broker-dealer and wish to receive
          10 additional copies of the prospectus and 10 copies of
          any amendments or supplements thereto.

          If the undersigned is not a broker-dealer, the
          undersigned represents that it is not engaged in, and
          does not intend to engage in, a distribution of Exchange
          Securities.  If the undersigned is a broker-dealer that
          will receive Exchange Securities for its own account in
          exchange for Securities that were acquired as a result of
          market-making activities or other trading activities, it
          acknowledges that it will deliver a prospectus in
          connection with any resale of such Exchange Securities;
          however, by so acknowledging and delivering a prospectus,
          the undersigned will not be deemed to admit that it is an
          "underwriter" within the meaning of the Securities Act.

               Hartford, Connecticut 06102

          Ladies and Gentlemen:

                    We have acted as special counsel to HSB Group,
          Inc., a Connecticut corporation (the "Company"), and HSB
          Capital I, a business trust formed under the Business
          Trust Act of the State of Delaware (Chapter 38, Title 12,
          of the Delaware Code, 12 Del. C. SECTIONS 3801 et. seq.) (the
          "Issuer Trust"), in connection with the preparation of
          the Registration Statement on Form S-4 (the "Registration
          Statement") to be filed by the Company and the Issuer
          Trust with the Securities and Exchange Commission (the
          "Commission") on the date hereof.  The Registration
          Statement relates to the registration under the
          Securities Act of 1933, as amended (the "Act"), of
          $110,000,000 aggregate liquidation amount of Global
          Floating Rate Capital Securities, Series B (the "Capital
          Securities") in connection with a proposed exchange offer
          (the "Exchange Offer").

                    The Capital Securities are to be issued
          pursuant to the Amended and Restated Trust Agreement of
          the Issuer Trust, dated as of July 15, 1997 (the "Trust
          Agreement"), among Saul L. Basch, R. Kevin Price and
          Robert C. Walker, as administrative trustees, The First
          National Bank of Chicago, as property trustee (the
          "Property Trustee"), First Chicago Delaware Inc., as
          Delaware trustee, and the Company, as sponsor.

                    This opinion is being furnished in accordance
          with the requirements of Item 601(b)(5) of Regulation S-K
          under the Act.

                    In connection with this opinion, we have
          examined originals or copies, certified or otherwise
          identified to our satisfaction, of (i) the Registration
          Statement; (ii) an executed copy of the Registration
          Rights Agreement, dated as of July 15, 1997 (the
          "Registration Rights Agreement"), among the Company, the
          Issuer Trust, and Goldman, Sachs & Co.; (iii) the form of
          the Capital Securities and a specimen certificate
          thereof; (iv) the Certificate of Trust of the Issuer
          Trust filed with the Secretary of State of the State of
          Delaware on July 10, 1997; and (v) the Trust Agreement. 
          We have also examined originals or copies, certified or
          otherwise identified to our satisfaction, of such other
          documents, certificates and records as we have deemed
          necessary or appropriate as a basis for the opinions set
          forth herein.

                    In our examination, we have assumed the legal
          capacity of all natural persons, the genuineness of all
          signatures, the authenticity of all documents submitted
          to us as originals, the conformity to original documents
          of all documents submitted to us as certified or
          photostatic copies and the authenticity of the originals
          of such latter documents.  In making our examination of
          documents executed by parties other than the Issuer
          Trust, we have assumed that such parties had the power,
          corporate or other, to enter into and perform all
          obligations thereunder and have also assumed the due
          authorization by all requisite action, corporate or
          other, and execution and delivery by such parties of such
          documents and the validity and binding effect thereof on
          such parties.  As to any facts material to the opinions
          expressed herein which we did not independently establish
          or verify, we have relied upon oral or written statements
          and representations of officers, trustees and other
          representatives of the Company, the Issuer Trust and
          others.

                    Members of our firm are admitted to the bar in 
          the States of New York and Delaware, and we do not
          express any opinion as to the laws of any other
          jurisdiction other than the laws of the United States of
          America to the extent referred to specifically herein.

                    Based upon and subject to the foregoing, we are
          of the opinion that:

                    1. The Capital Securities have been duly
          authorized for issuance by the Issuer Trust, and when (i)
          the Registration Statement becomes effective and the
          Trust Agreement has been qualified under the Trust
          Indenture Act of 1939, as amended, and (ii) the Capital
          Securities are duly executed, authenticated and issued in
          accordance with the Trust Agreement and delivered and
          issued in the Exchange Offer as contemplated by the
          Registration Rights Agreement and the Registration
          Statement, the Capital Securities will be duly and
          validly issued, fully paid and nonassessable undivided
          beneficial interests in the assets of the Issuer Trust.
          We bring to your attention, however, that the holders of
          the Capital Securities may be obligated, pursuant to the
          Trust Agreement, to (i) provide indemnity and/or security
          in connection with, and pay taxes or governmental charges
          arising from, transfers of Capital Securities and the
          issuance of replacement Capital Securities and (ii)
          provide security and indemnity in connection with
          requests of or directions to the Property Trustee in
          connection with the exercise of its rights and powers
          under the Trust Agreement.

                    2. The holders of the Capital Securities will
          be entitled to the same limitation of personal liability
          extended to stockholders of private corporations for
          profit organized under the General Corporation Law of the
          State of Delaware. 

                    We hereby consent to the filing of this opinion
          with the Commission as an exhibit to the Registration
          Statement.  We also consent to the reference to our firm
          under the caption "Validity of Securities" in the
          Registration Statement.  In giving this consent, we do
          not thereby admit that we are included in the category of
          persons whose consent is required under Section 7 of the
          Act or the rules and regulations of the Commission.  This
          opinion is expressed as of the date hereof, and we
          disclaim any undertaking to advise you of any subsequent
          changes in the facts stated or assumed herein or of any
          subsequent changes in applicable law.

                                   Very truly yours,

                              /S/Skadden, Arps, Slate, Meagher & Flom LLP

                    Re:  Global Floating Rate Capital 
                         Securities of HSB Capital I

          Ladies and Gentlemen:

                    The undersigned, an attorney-at-law admitted to
          practice in the State of Connecticut, is Senior Vice
          President and General Counsel of HSB Group, Inc., a
          Connecticut corporation (the "Company").  As such, I am
          familiar with the proceedings taken by the Company and
          HSB Capital I, a trust formed under the laws of the State
          of Delaware and all of the common securities of which are
          owned by the Company (the "Issuer Trust"), in connection
          with the preparation of a Registration Statement on Form
          S-4 (the "Registration Statement") filed with the
          Securities and Exchange Commission (the "Commission") on
          the date hereof by the Company and the Issuer Trust with
          respect to the registration under the Securities Act of
          1933, as amended (the "Act"), (i) by the Issuer Trust of
          $110 million aggregate liquidation amount of Global
          Floating Rate Capital Securities, Series B (the "Exchange
          Capital Securities"); (ii) by the Company of its
          guarantee of payment of cash distributions and payments
          on liquidation of the Issuer Trust or redemption of the
          Exchange Capital Securities pursuant to the Exchange
          Guarantee Agreement (the "Exchange Guarantee Agreement")
          and (iii) by the Company of $110 million aggregate
          principal amount of its Global Junior Subordinated
          Deferrable Interest Debentures, Series B due July 15,
          2027 (the "Exchange Junior Subordinated Debentures").

                    This opinion is being furnished in accordance
          with the requirements of Item 601(b)(5) of Regulation S-K
          under the Act.

                    In rendering the opinions set forth herein,
          either I or other members of my staff subject to my
          supervision have examined (i) the Registration Statement
          filed with the Commission on the date hereof (the
          "Registration Statement"), (ii) the Registration Rights
          Agreement dated as of July 15, 1997 (the "Registration
          Rights Agreement"), among the Company, the Issuer Trust
          and Goldman Sachs & Co. and Conning & Co., (iii) the
          Indenture and the First Supplemental Indenture dated as
          of July 15, 1997 (collectively, the "Indenture") between
          The First National Bank of Chicago, as Indenture Trustee,
          and the Company, (iv) the Amended and Restated Trust
          Agreement, dated as of July 15, 1997 (the "Trust
          Agreement") among Saul L. Basch, R. Kevin Price and
          Robert C. Walker, as Administrative Trustees, The First
          National Bank of Chicago, as property trustee, First
          Chicago Delaware Inc., as Delaware trustee and the
          Company, as sponsor, (v) the form of the Exchange Junior
          Subordinated Debentures and a specimen certificate
          thereof; (vi) the Exchange Guarantee Agreement, (vii) the
          Certificate of Incorporation and By-Laws of the Company
          and (viii) originals or copies, certified or otherwise
          identified to our satisfaction, of such other agreements,
          instruments, certificates of public officials and
          corporate officers of the Company and such other
          documents, certificates, records, authorizations and
          proceedings, as have been deemed requisite to enable me
          to express the opinions hereinafter set forth.

                    In our examination, we have assumed the legal
          capacity of all natural persons, the genuineness of all
          signatures, the authenticity of all documents submitted
          to us as originals, the conformity to original documents
          of all documents submitted to us as certified or
          photocopies and the authenticity of the originals of such
          latter documents.  In making our examination of documents
          executed by parties other than the Company, we have
          assumed that such parties had the power, corporate or
          other, to enter into and perform all obligations
          thereunder and have also assumed the due authorization by
          all requisite action, corporate or other, and execution
          and delivery by such parties of such documents and the
          validity and binding effect thereof on such parties.

                    Based on the foregoing, it is my opinion that:

                    (a)  The Exchange Guarantee Agreement has
               been duly authorized by the Company, and when
               (i) the Trust Agreement and Indenture have been
               qualified under the Trust Indenture Act of
               1939, as amended (the "TIA"), and (ii) the
               Exchange Guarantee Agreement is duly executed
               and delivered by the Company and issued in the
               exchange offer as contemplated by the
               Registration Rights Agreement and the
               Registration Statement, the Exchange Guarantee
               Agreement will constitute a valid, legal and
               binding agreement of the Company in favor of
               the holders of Exchange Capital Securities,
               enforceable against the Company in accordance
               with its terms, except to the extent that
               enforcement thereof may be limited by (1)
               bankruptcy, reorganization, insolvency,
               moratorium, fraudulent conveyance or other
               similar laws now or hereafter in effect
               relating to creditors' rights generally and (2)
               general principles of equity (regardless of
               whether enforceability is considered in a
               proceeding at law or in equity); and

                    (b)  The Exchange Junior Subordinated
               Debentures have been duly authorized for
               issuance and sale by the Company and when (i)
               the Trust Agreement and Indenture have been
               qualified under the TIA and (ii) the Exchange
               Junior Subordinated Debentures are duly
               executed, authenticated and issued in
               accordance with the Indenture and delivered and
               issued in the exchange offer as contemplated by
               the Registration Rights Agreement and the
               Registration Statement, the Exchange Junior
               Subordinated Debentures will constitute valid
               and binding obligations of the Company
               enforceable against the Company in accordance
               with their terms, except to the extent that
               enforcement thereof may be limited by (1)
               bankruptcy, reorganization, insolvency,
               moratorium, fraudulent conveyance or other
               similar laws now or hereafter in effect
               relating to creditors' rights generally and (2)
               general principles of equity (regardless of
               whether enforceability is considered in a
               proceeding at law or in equity).

                    My opinions are subject to the following
          qualification:

                    (a)  I am qualified to practice law in the
               State of Connecticut.  The opinions expressed
               herein are limited to the law of the State of
               Connecticut.

                    I hereby consent to the filing of this opinion
          with the Commission as an exhibit to the Registration
          Statement.  I also consent to the reference to myself
          under the caption "Validity of Securities" in the
          Registration Statement.

                                        Very truly yours,

                         Re:  Registration Statement on Form S-4 

          Ladies and gentlemen:

                    We have acted as special tax counsel to HSB
          Group, Inc., a Connecticut corporation (the "Company"),
          and HSB Capital I, a Delaware business trust (the "Issuer
          Trust"), in connection with the exchange of up to 110,000
          of the Issuer Trust's Global Floating Rate Capital
          Securities, Series B, liquidation amount $1,000 per
          preferred security (the "Exchange Capital Securities")
          for a like liquidation amount of the Issuer Trust's
          outstanding Global Floating Rate Capital Securities,
          Series A (the "Original Capital Securities") (the
          "Exchange Offer").  Pursuant to the Exchange Offer, the
          Company is offering to exchange up to $110,000,000
          aggregate principal amount of its Global Floating Rate
          Junior Subordinated Deferrable Interest Debentures,
          Series B, due July 15, 2027 (which date may be shortened,
          in certain circumstances, to a date not earlier than
          April 15, 2012) (the "Exchange Debentures") for a like
          aggregate principal amount of Global Floating Rate Junior
          Subordinated Deferrable Interest Debentures, Series A,
          due July 15, 2027 (which date may be shortened, in
          certain circumstances, to a date not earlier than April
          15, 2012) (the "Original Debentures").

                    In rendering our opinion, we have participated
          in the preparation of the above-captioned registration
          statement on Form S-4 (the "Registration Statement")
          filed with the Securities and Exchange Commission (the
          "Commission") on the date hereof.  Our opinion is
          conditioned on, among other things, the initial and
          continuing accuracy of the facts, information, covenants
          and representations set forth in the Registration
          Statement and certain other documents and the statements
          and representations made by officers of the Company.  In
          our examination, we have assumed the genuineness of all
          signatures, the legal capacity of natural persons, the
          authenticity of all documents submitted to us as
          originals, the conformity to original documents of all
          documents submitted to us as certified or photostatic
          copies and the authenticity of the originals of such
          documents.  We also have assumed that the transactions
          related to the exchange of Exchange Capital Securities
          for Original Capital Securities and Exchange Debentures
          for Original Debentures will be consummated in the manner
          contemplated by the Registration Statement.

                    In rendering our opinion, we have considered
          the current provisions of the Internal Revenue Code of
          1986, as amended, Treasury regulations promulgated
          thereunder, judicial decisions and Internal Revenue
          Service rulings, all of which are subject to change,
          which changes may be retroactively applied.  A change in
          the authorities upon which our opinion is based could
          affect our conclusions.  There can be no assurances,
          moreover, that any of the opinions expressed herein will
          be accepted by the Internal Revenue Service or, if
          challenged, by a court.

                    Based solely upon the foregoing, we are of the
          opinion that, although the summary set forth in the
          Registration Statement under the heading "Certain Federal
          Income Tax Consequences" does not purport to discuss all
          possible United States federal income tax consequences of
          the exchange of Exchange Capital Securities for Original
          Capital Securities and Exchange Debentures for Original
          Debentures, such summary constitutes, in all material
          respects, a fair and accurate summary of the United
          States federal income tax consequences of such exchange
          under current United States federal income tax law.

                    Except as set forth above, we express no
          opinion to any party as to the tax consequences, whether
          federal, state, local or foreign, of the exchange of
          Exchange Capital Securities for Original Capital
          Securities or Exchange Debentures for Original Debentures
          or of any transaction related to or contemplated by the
          Exchange Offer.  This opinion is furnished to you solely
          for your benefit in connection with the Exchange Offer
          and is not to be used, circulated, quoted or otherwise
          referred to for any other purpose or relied upon by any
          other person without our prior written consent.  We
          consent to the use of our name under the heading
          "Validity of Securities" in the Registration Statement. 
          We hereby consent to the filing of this opinion with the
          Commission as Exhibit 8 to the Registration Statement. 
          In giving this consent, we do not thereby admit that we
          are within the category of persons whose consent is
          required under Section 7 of the Securities Act of 1933 or
          the rules and regulations of the Commission promulgated
          thereunder.  This opinion is expressed as of the date
          hereof, unless otherwise expressly stated, and we
          disclaim any undertaking to advise you of any subsequent
          changes of the facts stated or assumed herein or any
          subsequent changes in applicable law.  

                                   Very truly yours,


                                   /S/ Skadden, Arps, Slate, Meagher

               THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT
          THE UNDERSIGNED HAS FULL POWER AND AUTHORITY TO TENDER,
          EXCHANGE, SELL, ASSIGN AND TRANSFER THE ORIGINAL CAPITAL
          SECURITIES TENDERED HEREBY AND THAT, WHEN THE SAME ARE

          MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE AND CLEAR
          OF ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND
          THAT THE ORIGINAL CAPITAL SECURITIES TENDERED HEREBY ARE
          NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES. THE

          ADDITIONAL DOCUMENTS DEEMED BY THE COMPANY, THE ISSUER
          TRUST OR THE EXCHANGE AGENT TO BE NECESSARY OR DESIRABLE TO

          holder(s) (which term, for purposes of this document, shall
          include any participant in DTC) of the Original Capital
          Securities tendered hereby should be printed above, if they
          are not already set forth above, as they appear on the
          Certificates representing such Original Capital Securities.
          The Certificate number(s) and the Original Capital
          Securities that the undersigned wishes to tender should be
          indicated in the appropriate boxes above. 

               If any tendered Original Capital Securities are not
          exchanged pursuant to the Exchange Offer for any reason, or
          if Certificates are submitted for more Original Capital
          Securities than are tendered or accepted for exchange,
          Certificates for such nonexchanged or nontendered Original
          Capital Securities will be returned (or, in the case of
          Original Capital Securities tendered by book-entry
          transfer, such Original Capital Securities will be credited
          to an account maintained at DTC), without expense to the
          tendering holder, promptly following the expiration or
          termination of the Exchange Offer.

          Capital Securities pursuant to any one of the procedures
          described in "The Exchange Offer-Procedures for Tendering

          Original Capital Securities, constitute a binding agreement
          between the undersigned, the Company and the Issuer Trust
          upon the terms and subject to the conditions of the
          Exchange Offer. 

               The undersigned recognizes that, under certain
          circumstances set forth in the Prospectus, the Company and
          the Issuer Trust may not be required to accept for exchange
          any of the Original Capital Securities tendered hereby.  

               Unless otherwise indicated herein in the box entitled
          "Special Issuance Instructions" below, the undersigned
          hereby directs that the Exchange Capital Securities be
          issued in the name(s) of the undersigned or, in the case of
          a book-entry transfer of Original Capital Securities, that
          such Exchange Capital Securities be credited to the account
          indicated above maintained at DTC. If applicable,
          substitute Certificates representing Original Capital
          Securities not exchanged or not accepted for exchange will
          be issued to the undersigned or, in the case of a
          book-entry transfer of Original Capital Securities, will be

          THIS LETTER OF TRANSMITTAL, OR EFFECTING DELIVERY OF AN
          AGENT'S MESSAGE IN LIEU THEREOF, THE UNDERSIGNED HEREBY
          REPRESENTS AND AGREES THAT (I) THE UNDERSIGNED IS NOT AN
          "AFFILIATE" OF THE COMPANY OR THE ISSUER TRUST, (II) ANY
          EXCHANGE CAPITAL SECURITIES TO BE RECEIVED BY THE
          UNDERSIGNED ARE BEING ACQUIRED IN THE ORDINARY COURSE OF
          ITS BUSINESS, (III) THE UNDERSIGNED HAS NO ARRANGEMENT OR
          UNDERSTANDING WITH ANY PERSON TO PARTICIPATE IN A
          DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES ACT) OF
          EXCHANGE CAPITAL SECURITIES TO BE RECEIVED IN THE EXCHANGE
          OFFER, AND (IV) IF THE UNDERSIGNED IS NOT A BROKER-DEALER,

          EXCHANGE OFFER AND EXECUTING THIS LETTER OF TRANSMITTAL, OR
          EFFECTING DELIVERY OF AN AGENT'S MESSAGE IN LIEU THEREOF, A
          HOLDER OF ORIGINAL CAPITAL SECURITIES WHICH IS A
          BROKER-DEALER REPRESENTS AND AGREES, CONSISTENT WITH
          CERTAIN INTERPRETIVE LETTERS ISSUED BY THE STAFF OF THE
          DIVISION OF CORPORATION FINANCE OF THE SECURITIES AND
          EXCHANGE COMMISSION TO THIRD PARTIES, THAT (A) SUCH
          ORIGINAL CAPITAL SECURITIES HELD BY THE BROKER-DEALER ARE
          HELD ONLY AS A NOMINEE, OR (B) SUCH ORIGINAL CAPITAL
          SECURITIES WERE ACQUIRED BY SUCH BROKER-DEALER FOR ITS OWN
          ACCOUNT AS A RESULT OF MARKET-MAKING ACTIVITIES OR OTHER
          TRADING ACTIVITIES AND IT WILL DELIVER THE PROSPECTUS (AS
          AMENDED OR SUPPLEMENTED FROM TIME TO TIME) MEETING THE
          REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY
          RESALE OF SUCH EXCHANGE CAPITAL SECURITIES (PROVIDED THAT,
          BY SO ACKNOWLEDGING AND BY DELIVERING A PROSPECTUS, SUCH
          BROKER-DEALER WILL NOT BE DEEMED TO ADMIT THAT IT IS AN
          "UNDERWRITER" WITHIN THE MEANING OF THE SECURITIES ACT). 

               THE COMPANY AND THE ISSUER TRUST HAVE AGREED THAT,
          SUBJECT TO THE PROVISIONS OF THE REGISTRATION RIGHTS
          AGREEMENT, THE PROSPECTUS, AS IT MAY BE AMENDED OR

          PARTICIPATING BROKER-DEALER (AS DEFINED BELOW) IN CONNECTION
          WITH RESALES OF EXCHANGE CAPITAL SECURITIES RECEIVED IN
          EXCHANGE FOR ORIGINAL CAPITAL SECURITIES, WHERE SUCH
          ORIGINAL CAPITAL SECURITIES WERE ACQUIRED BY SUCH
          PARTICIPATING BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT
          OF MARKET-MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES, FOR
          A PERIOD ENDING 90 DAYS AFTER THE EXPIRATION DATE (SUBJECT
          TO EXTENSION UNDER CERTAIN LIMITED CIRCUMSTANCES DESCRIBED
          IN THE PROSPECTUS) OR, IF EARLIER, WHEN ALL SUCH EXCHANGE
          CAPITAL SECURITIES HAVE BEEN DISPOSED OF BY SUCH
          PARTICIPATING BROKER-DEALER. IN THAT REGARD, EACH
          BROKER-DEALER WHO ACQUIRED ORIGINAL CAPITAL SECURITIES FOR
          ITS OWN ACCOUNT AS A RESULT OF MARKET-MAKING OR OTHER
          TRADING ACTIVITIES (A "PARTICIPATING BROKER-DEALER"), BY
          TENDERING SUCH ORIGINAL CAPITAL SECURITIES AND EXECUTING
          THIS LETTER OF TRANSMITTAL, OR EFFECTING DELIVERY OF AN
          AGENT'S MESSAGE IN LIEU THEREOF, AGREES THAT, UPON RECEIPT
          OF NOTICE FROM THE COMPANY OR THE ISSUER TRUST OF THE
          OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY FACT WHICH
          MAKES ANY STATEMENT CONTAINED OR INCORPORATED BY REFERENCE
          IN THE PROSPECTUS UNTRUE IN ANY MATERIAL RESPECT OR WHICH
          CAUSES THE PROSPECTUS TO OMIT TO STATE A MATERIAL FACT
          NECESSARY IN ORDER TO MAKE THE STATEMENTS CONTAINED OR
          INCORPORATED BY REFERENCE THEREIN, IN LIGHT OF THE
          CIRCUMSTANCES UNDER WHICH THEY WERE MADE, NOT MISLEADING OR
          OF THE OCCURRENCE OF CERTAIN OTHER EVENTS SPECIFIED IN THE
          REGISTRATION RIGHTS AGREEMENT, SUCH PARTICIPATING BROKER-
          DEALER WILL SUSPEND THE SALE OF EXCHANGE CAPITAL SECURITIES
          PURSUANT TO THE PROSPECTUS UNTIL THE COMPANY AND THE ISSUER
          TRUST HAVE AMENDED OR SUPPLEMENTED THE PROSPECTUS TO CORRECT
          SUCH MISSTATEMENT OR OMISSION AND HAVE FURNISHED COPIES OF
          THE AMENDED OR SUPPLEMENTED PROSPECTUS TO THE PARTICIPATING
          BROKER-DEALER OR THE COMPANY OR THE ISSUER TRUST HAS GIVEN
          NOTICE THAT THE SALE OF THE EXCHANGE CAPITAL SECURITIES MAY
          BE RESUMED, AS THE CASE MAY BE. IF THE COMPANY OR THE ISSUER
          TRUST GIVES SUCH NOTICE TO SUSPEND THE SALE OF THE EXCHANGE
          CAPITAL SECURITIES, THEY SHALL EXTEND THE 90-DAY PERIOD
          REFERRED TO ABOVE DURING WHICH PARTICIPATING BROKER-DEALERS
          ARE ENTITLED TO USE THE PROSPECTUS IN CONNECTION WITH THE
          RESALE OF EXCHANGE CAPITAL SECURITIES BY THE NUMBER OF DAYS
          DURING THE PERIOD FROM AND INCLUDING THE DATE OF THE GIVING
          OF SUCH NOTICE TO AND INCLUDING THE DATE WHEN PARTICIPATING
          BROKER-DEALERS SHALL HAVE RECEIVED COPIES OF THE
          SUPPLEMENTED OR AMENDED PROSPECTUS NECESSARY TO PERMIT
          RESALES OF THE EXCHANGE CAPITAL SECURITIES OR TO AND
          INCLUDING THE DATE ON WHICH THE COMPANY OR THE ISSUER TRUST
          HAS GIVEN NOTICE THAT THE SALE OF EXCHANGE CAPITAL
          SECURITIES MAY BE RESUMED, AS THE CASE MAY BE. 

               AS A RESULT, A PARTICIPATING BROKER-DEALER WHO INTENDS
          TO USE THE PROSPECTUS IN CONNECTION WITH RESALES OF EXCHANGE
          CAPITAL SECURITIES RECEIVED IN EXCHANGE FOR ORIGINAL CAPITAL
          SECURITIES PURSUANT TO THE EXCHANGE OFFER MUST NOTIFY THE
          COMPANY AND THE ISSUER TRUST, OR CAUSE THE COMPANY AND THE
          ISSUER TRUST TO BE NOTIFIED, ON OR PRIOR TO THE EXPIRATION
          DATE, THAT IT IS A PARTICIPATING BROKER-DEALER. SUCH NOTICE

               (i)  this Letter of Transmittal is signed by the

                    this document, shall include any participant in
                    DTC whose name appears on a security position
                    listing as the owner of the Original Capital
                    Securities) of Original Capital Securities
                    tendered herewith, unless such holder(s) has
                    completed either the box entitled "Special
                    Issuance Instructions" or the box entitled
                    "Special Delivery Instructions" above, or  

               (ii) such Original Capital Securities are tendered for

                    Institution.

          guarantee the signature(s) on this Letter of Transmittal. 
          See Instruction 5. 
           
               3.   Inadequate Space. If the space provided in the
          box captioned "Description of Original Capital Securities"
          is inadequate, the Certificate number(s) and/or the
          principal amount of Original Capital Securities and any
          other required information should be listed on a separate
          signed schedule which is attached to this Letter of
          Transmittal. 
           
               4.   Partial Tenders and Withdrawal Rights. Tenders of
          Original Capital Securities will be accepted only in the
          principal amount of $1,000 (1 Capital Security) and
          integral multiples of $1,000 in excess thereof, provided
          that if any Original Capital Securities are tendered for
          exchange in part, the untendered principal amount thereof
          must be $1,000 (1 Capital Security) or any integral
          multiple of $1,000 in excess thereof. If less than all the
          Original Capital Securities evidenced by any Certificate
          submitted are to be tendered, fill in the principal amount
          of Original Capital Securities which are to be tendered in
          the box entitled "Principal Amount of Original Capital
          Securities Tendered." In such case, new Certificate(s) for
          the remainder of the Original Capital Securities that were
          evidenced by your old Certificate(s) will only be sent to
          the holder of the Original Capital Security, promptly after
          the Expiration Date. All Original Capital Securities
          represented by Certificates delivered to the Exchange Agent
          will be deemed to have been tendered unless otherwise
          indicated.  

               Except as otherwise provided herein, tenders of
          Original Capital Securities may be withdrawn at any time on
          or prior to the Expiration Date. In order for a withdrawal
          to be effective on or prior to that time, a written,
          telegraphic, telex or facsimile transmission of such notice
          of withdrawal must be timely received by the Exchange Agent
          at one of its addresses set forth above or in the
          Prospectus on or prior to the Expiration Date. Any such
          notice of withdrawal must specify the name of the person
          who tendered the Original Capital Securities to be
          withdrawn, the aggregate principal amount of Original
          Capital Securities to be withdrawn, and (if Certificates
          for Original Capital Securities have been tendered) the
          name of the registered holder of the Original Capital
          Securities as set forth on the Certificate for the Original
          Capital Securities, if different from that of the person
          who tendered such Original Capital Securities. If
          Certificates for the Original Capital Securities have been
          delivered or otherwise identified to the Exchange Agent,
          then prior to the physical release of such Certificates for
          the Original Capital Securities, the tendering holder must
          submit the serial numbers shown on the particular
          Certificates for the Original Capital Securities to be
          withdrawn and the signature on the notice of withdrawal
          must be guaranteed by an Eligible Institution, except in
          the case of Original Capital Securities tendered for the
          account of an Eligible Institution. If Original Capital
          Securities have been tendered pursuant to the procedures
          for book-entry transfer set forth in the Prospectus under
          "The Exchange Offer-Procedures for Tendering Original
          Capital Securities," the notice of withdrawal must specify
          the name and number of the account at DTC to be credited
          with the withdrawal of Original Capital Securities, in
          which case a notice of withdrawal will be effective if
          delivered to the Exchange Agent by written, telegraphic,
          telex or facsimile transmission. Withdrawals of tenders of
          Original Capital Securities may not be rescinded. Original
          Capital Securities properly withdrawn will not be deemed
          validly tendered for purposes of the Exchange Offer, but
          may be retendered at any subsequent time on or prior to the
          Expiration Date by following any of the procedures
          described in the Prospectus under "The Exchange
          Offer-Procedures for Tendering Original Capital
          Securities." 

               All questions as to the validity, form and eligibility
          (including time of receipt) of such withdrawal notices will
          be determined by the Company and the Issuer Trust, in their
          sole discretion, whose determination shall be final and
          binding on all parties. Neither the Company, the Issuer
          Trust, any affiliates or assigns of the Company or the
          Issuer Trust, the Exchange Agent nor any other person shall
          be under any duty to give any notification of any
          irregularities in any notice of withdrawal or incur any
          liability for failure to give any such notification. Any
          Original Capital Securities which have been tendered but
          which are withdrawn will be returned to the holder thereof
          without cost to such holder promptly after withdrawal.

               5.   Signatures on Letter of Transmittal, Assignments
          and Endorsements. If this Letter of Transmittal is signed
          by the registered holder(s) of the Original Capital
          Securities tendered hereby, the signature(s) must
          correspond exactly with the name(s) as written on the face
          of the Certificate(s) without alteration, enlargement or
          any change whatsoever. 

               If any of the Original Capital Securities tendered
          hereby are owned of record by two or more joint owners, all
          such owners must sign this Letter of Transmittal. 

          If any tendered Original Capital Securities are registered
          in different name(s) on several Certificates, it will be
          necessary to complete, sign and submit as many separate
          Letters of Transmittal (or facsimiles thereof) as there are
          different registrations of Certificates. 

               If this Letter of Transmittal or any Certificates or
          bond powers are signed by trustees, executors,
          administrators, guardians, attorneys-in-fact, officers of
          corporations or others acting in a fiduciary or
          representative capacity, such persons should so indicate
          when signing and must submit proper evidence satisfactory
          to the Company and the Issuer Trust, in their sole
          discretion, of each such person's authority so to act. 

               When this Letter of Transmittal is signed by the
          registered owner(s) of the Original Capital Securities
          listed and transmitted hereby, no endorsement(s) of
          Certificate(s) or separate bond power(s) are required
          unless Exchange Capital Securities are to be issued in the
          name of a person other than the registered holder(s).
          Signature(s) on such Certificate(s) or bond power(s) must
          be guaranteed by an Eligible Institution. 

               If this Letter of Transmittal is signed by a person
          other than the registered owner(s) of the Original Capital
          Securities listed, the Certificates must be endorsed or
          accompanied by appropriate bond powers, signed exactly as
          the name or names of the registered owner(s) appear(s) on
          the Certificates, and also must be accompanied by such
          opinions of counsel, certifications and other information
          as the Company, the Issuer Trust or the Trustee for the
          Original Capital Securities may require in accordance with
          the restrictions on transfer applicable to the Original
          Capital Securities. Signatures on such Certificates or bond
          powers must be guaranteed by an Eligible Institution. 

               6.   Special Issuance and Delivery Instructions. If
          Exchange Capital Securities are to be issued in the name of
          a person other than the signer of this Letter of
          Transmittal, or if Exchange Capital Securities are to be
          sent to someone other than the signer of this Letter of
          Transmittal or to an address other than that shown above,
          the appropriate boxes on this Letter of Transmittal should
          be completed. Certificates for Original Capital Securities
          not exchanged will be returned by mail or, if tendered by
          book-entry transfer, by crediting the account indicated
          above maintained at DTC. See Instruction 4. 
           
                7.  Irregularities. The Company and the Issuer Trust
          will determine, in their sole discretion, all questions as
          to the form of documents, validity, eligibility (including
          time of receipt) and acceptance for exchange of any tender
          of Original Capital Securities, which determination shall
          be final and binding on all parties. The Company and the
          Issuer Trust reserve the absolute right to reject any and
          all tenders determined by either of them not to be in
          proper form or the acceptance of which, or exchange for
          which, may, in the view of counsel to the Company and the
          Issuer Trust be unlawful. The Company and the Issuer Trust
          also reserve the absolute right, subject to applicable law,
          to waive any of the conditions of the Exchange Offer set
          forth in the Prospectus under "The Exchange
          Offer-Conditions to the Exchange Offer" or any conditions
          or irregularity in any tender of Original Capital
          Securities of any particular holder whether or not similar
          conditions or irregularities are waived in the case of
          other holders. The Company's and the Issuer Trust's
          interpretation of the terms and conditions of the Exchange
          Offer (including this Letter of Transmittal and the
          instructions hereto) will be final and binding. No tender
          of Original Capital Securities will be deemed to have been
          validly made until all irregularities with respect to such
          tender have been cured or waived. The Company, the Issuer
          Trust, any affiliates or assigns of the Company, the Issuer
          Trust, the Exchange Agent, or any other person shall not be
          under any duty to give notification of any irregularities
          in tenders or incur any liability for failure to give such
          notification. 

               8.   Questions, Requests For Assistance and Additional
          Copies. Questions and requests for assistance may be
          directed to the Exchange Agent at its address and telephone
          number set forth on the front of this Letter of
          Transmittal. Additional copies of the Prospectus, the
          Notice of Guaranteed Delivery and this Letter of

          your broker, dealer, commercial bank, trust company or
          other nominee. 

               9.   31% Backup Withholding; Substitute Form W-9.
          Under U.S. Federal income tax law, a holder whose tendered
          Original Capital Securities are accepted for exchange is
          required to provide the Exchange Agent with such holder's
          correct taxpayer identification number ("TIN") on
          Substitute Form W-9 below. If the Exchange Agent is not
          provided with the correct TIN, the Internal Revenue Service
          (the "IRS") may subject the holder or other payee to a $50
          penalty. In addition, payments to such holders or other
          payees with respect to Original Capital Securities
          exchanged pursuant to the Exchange Offer may be subject to
          31% backup withholding. 

               The box in Part 2 of the Substitute Form W-9 may be
          checked if the tendering holder has not been issued a TIN
          and has applied for a TIN or intends to apply for a TIN in
          the near future. If the box in Part 2 is checked, the
          holder or other payee must also complete the Certificate of
          Awaiting Taxpayer Identification Number below in order to
          avoid backup withholding. Notwithstanding that the box in
          Part 2 is checked and the Certificate of Awaiting Taxpayer
          Identification Number is completed, the Exchange Agent will
          withhold 31% of all payments made prior to the time a
          properly certified TIN is provided to the Exchange Agent.
          The Exchange Agent will retain such amounts withheld during
          the 60-day period following the date of the Substitute Form
          W-9. If the holder furnishes the Exchange Agent with its
          TIN within 60 days after the date of the Substitute Form W-
          9, the amounts retained during the 60-day period will be
          remitted to the holder and no further amounts shall be
          retained or withheld from payments made to the holder
          thereafter. If, however, the holder has not provided the
          Exchange Agent with its TIN within such 60-day period,
          amounts withheld will be remitted to the IRS as backup
          withholding. In addition, 31% of all payments made
          thereafter will be withheld and remitted to the IRS until a
          correct TIN is provided. 

               The holder is required to give the Exchange Agent the
          TIN (e.g., social security number or employer
          identification number) of the registered owner of the
          Original Capital Securities or of the last transferee
          appearing on the transfers attached to, or endorsed on, the
          Original Capital Securities. If the Original Capital
          Securities are registered in more than one name or are not
          in the name of the actual owner, consult the enclosed
          "Guidelines for Certification of Taxpayer Identification
          Number on Substitute Form W-9" for additional guidance on
          which number to report. 

               Certain holders (including, among others,
          corporations, financial institutions and certain foreign
          persons) may not be subject to these backup withholding and
          reporting requirements. Such holders should nevertheless
          complete the attached Substitute Form W-9 below, and write
          "exempt" on the face thereof, to avoid possible erroneous
          backup withholding. A foreign person may qualify as an
          exempt recipient by submitting a properly completed IRS
          Form W-8, signed under penalties of perjury, attesting to
          that holder's exempt status. Please consult the enclosed
          "Guidelines for Certification of Taxpayer Identification
          Number on Substitute Form W-9" for additional guidance on
          which holders are exempt from backup withholding. 

               Backup withholding is not an additional U.S. Federal
          income tax. Rather, the U.S. Federal income tax liability
          of a person subject to backup withholding will be reduced
          by the amount of tax withheld. If withholding results in an
          overpayment of taxes, a refund may be obtained.

               10.  Waiver of Conditions. The Company and the Issuer
          Trust reserve the absolute right to waive satisfaction of
          any or all conditions enumerated in the Prospectus.

               11.  No Conditional Tenders. No alternative,
          conditional or contingent tenders will be accepted. All
          tendering holders of Original Capital Securities, by
          execution of this Letter of Transmittal, shall waive any
          right to receive notice of the acceptance of Original
          Capital Securities for exchange. 

               Neither the Company, the Issuer Trust, the Exchange
          Agent nor any other person is obligated to give notice of
          any defect or irregularity with respect to any tender of
          Original Capital Securities nor shall any of them incur any
          liability for failure to give any such notice. 

               12.  Lost, Destroyed or Stolen Certificates. If any
          Certificate(s) representing Original Capital Securities
          have been lost, destroyed or stolen, the holder should
          promptly notify the Exchange Agent. The holder will then be
          instructed as to the steps that must be taken in order to
          replace the Certificate(s). This Letter of Transmittal and
          related documents cannot be processed until the procedures
          for replacing lost, destroyed or stolen Certificate(s) have
          been followed. 

               13.  Security Transfer Taxes. Holders who tender their
          Original Capital Securities for exchange will not be
          obligated to pay any transfer taxes in connection
          therewith. If, however, Exchange Capital Securities are to
          be delivered to, or are to be issued in the name of, any
          person other than the registered holder of the Original
          Capital Securities tendered, or if a transfer tax is
          imposed for any reason other than the exchange of Original
          Capital Securities in connection with the Exchange Offer,
          then the amount of any such transfer tax (whether imposed
          on the registered holder or any other persons) will be
          payable by the tendering holder. If satisfactory evidence
          of payment of such taxes or exemption therefrom is not
          submitted with the Letter of Transmittal, the amount of
          such transfer taxes will be billed directly to such
          tendering holder. 
           
               IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE
          THEREOF) AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED
          BY THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.

          of all payments made to me on account of the Exchange
          Capital Securities shall be retained until I provide a
          taxpayer identification number to the Exchange Agent and
          that, if I do not provide my taxpayer identification number
          within 60 days, such retained amounts shall be remitted to
          the Internal Revenue Service as backup withholding and 31%
          of all reportable payments made to me thereafter will be
          withheld and remitted to the Internal Revenue Service until
          I provide a taxpayer identification number.

                                        October ___, 1997


          The First National Bank of Chicago
          One First National Plaza
          Suite 0126
          Chicago, Illinois 60670-0126

          Ladies and Gentlemen:

               HSB Capital I, a trust formed under the laws of the
          State of Delaware (the "Trust") proposes to make an offer
          (the "Exchange Offer") to exchange its Global Floating
          Rate Capital Securities, Series A (Liquidation Amount
          $1,000 per Capital Security) (the "Original Capital
          Securities") for its Global Floating Rate Capital
          Securities, Series B (Liquidation Amount $1,000 per
          Capital Security) (the "Exchange Capital Securities"). 
          All of the beneficial interests represented by common
          securities of the Trust are owned by HSB Group, Inc. a
          Connecticut corporation (the "Corporation").  The terms
          and conditions of the Exchange Offer as currently
          contemplated are set forth in a prospectus, dated ______,
          1997 (the "Prospectus"), to be distributed to all record
          holders of the Original Capital Securities.  The Original
          Capital Securities and the Exchange Capital Securities
          are collectively referred to herein as the "Securities."

               The Trust hereby appoints The First National Bank of
          Chicago to act as exchange agent (the "Exchange Agent")
          in connection with the Exchange Offer.  References
          hereinafter to "you" shall refer to The First National
          Bank of Chicago.

               The Exchange Offer is expected to be commenced by
          the Trust on or about _______, 1997.  The Letter of
          Transmittal accompanying the Prospectus (or in the case
          of book entry securities, the ATOP system) is to be used
          by the holders of the Original Capital Securities to
          accept the Exchange Offer and contains instructions with
          respect to (i) the delivery of certificates for Original
          Capital Securities tendered in connection therewith and
          (ii) the book-entry transfer of Securities to the
          Exchange Agent's account.

               The Exchange Offer shall expire at 5:00 P.M., New
          York City time, on _______, 1997 or on such later date or
          time to which the Trust may extend the Exchange Offer
          (the "Expiration Date").  Subject to the terms and
          conditions set forth in the Prospectus, the Trust
          expressly reserves the right to extend the Exchange Offer
          from time to time by giving oral (to be confirmed in
          writing) or written notice to you before 9:00 A.M., New
          York City time, on the business day following the
          previously scheduled Expiration Date.

               The Trust expressly reserves the right to amend or
          terminate the Exchange Offer, and not to accept for
          exchange any Original Capital Securities not theretofore
          accepted for exchange, upon the occurrence of any of the
          conditions of the Exchange Offer specified in the
          Prospectus under the caption "The Exchange Offer--
          Conditions to the Exchange Offer."  The Trust will give
          oral (confirmed in writing) or written notice of any
          amendment, termination or nonacceptance of Original
          Capital Securities to you promptly after any amendment,
          termination or nonacceptance.

               In carrying out your duties as Exchange Agent, you
          are to act in accordance with the following instructions:

               1.   You will perform such duties and only such
          duties as are specifically set forth in the section of
          the Prospectus captioned "The Exchange Offer" or as
          specifically set forth herein; provided, however, that in
          no way will your general duty to act in good faith be
          discharged by the foregoing.

               2.   You will establish an account with respect to
          the Original Capital Securities at The Depository Trust
          Company (the "Book-Entry Transfer Facility") for purposes
          of the Exchange Offer within two business days after the
          date of the Prospectus, and any financial institution
          that is a participant in the Book-Entry Transfer
          Facility's system may make book-entry delivery of the
          Original Capital Securities by causing the Book-Entry
          Transfer Facility to transfer such Original Capital
          Securities into your account in accordance with the Book-
          Entry Transfer Facility's procedure for such transfer.

               3.   You are to examine each of the Letters of
          Transmittal and certificates for Original Capital
          Securities (or confirmation of book-entry transfer into
          your account at the Book-Entry Transfer Facility) and any
          other documents delivered or mailed to you by or for
          holders of the Original Capital Securities to ascertain
          whether: (i) the Letters of Transmittal and any such
          other documents are duly executed and properly completed
          in accordance with instructions set forth therein and
          (ii) the Original Capital Securities have otherwise been
          properly tendered.  In each case where the Letter of
          Transmittal or any other document has been improperly
          completed or executed or any of the certificates for
          Original Capital Securities are not in proper form for
          transfer or some other irregularity in connection with
          the acceptance of the Exchange Offer exists, you will
          endeavor to inform the presenters of the need for
          fulfillment of all requirements and to take any other
          action as may be necessary or advisable to cause such
          irregularity to be corrected. 

               4.   With the approval of any Administrative Trustee
          of the Trust or any person designated in writing by the
          Corporation (a "Designated Officer") or any other party
          designated by any such Administrative Trustee or
          Designated Officer in writing, you are authorized to
          waive any irregularities in connection with any tender of
          Original Capital Securities pursuant to the Exchange
          Offer. 

               5.   Tenders of Original Capital Securities may be
          made only as set forth in the Letter of Transmittal and
          in the section of the Prospectus captioned "The Exchange
          Offer--Procedures for Tendering Original Capital
          Securities," and Original Capital Securities shall be
          considered properly tendered to you only when tendered in
          accordance with the procedures set forth therein.

               Notwithstanding the provisions of this paragraph 5,
          Original Capital Securities which any Administrative
          Trustee of the Trust or Designated Officer of the
          Corporation shall approve as having been properly
          tendered shall be considered to be properly tendered
          (such approval, if given orally, shall be confirmed in
          writing).

               6.   You shall advise the Trust and the Corporation
          with respect to any Original Capital Securities received
          subsequent to the Expiration Date and accept their
          instructions with respect to disposition of such Original
          Capital Securities. 

               7.   You shall accept tenders:

               (a)  in cases where the Original Capital Securities
          are registered in two or more names only if signed by all
          named holders;

               (b)  in cases where the signing person (as indicated
          on the Letter of Transmittal) is acting in a fiduciary or
          a representative capacity only when proper evidence of
          such person's authority so to act is submitted; and 

               (c)  from persons other than the registered holder
          of Original Capital Securities provided that customary
          transfer requirements, including any applicable transfer
          taxes, are fulfilled.

               You shall accept partial tenders of Original Capital
          Securities where so indicated and as permitted in the
          Letter of Transmittal and deliver certificates for
          Original Capital Securities to the transfer agent for
          split-up and return any untendered Original Capital
          Securities to the holder (or such other person as may be
          designated in the Letter of Transmittal) as promptly as
          practicable after expiration or termination of the
          Exchange Offer.

               8.   Upon satisfaction or waiver of all of the
          conditions to the Exchange Offer, the Trust will notify
          you (such notice if given orally, to be confirmed in
          writing) of its acceptance, promptly after the Expiration
          Date, of all Original Capital Securities properly
          tendered and you, on behalf of the Trust, will exchange
          such Original Capital Securities for Exchange Capital
          Securities and cause such Original Capital Securities to
          be canceled.  Delivery of Exchange Capital Securities
          will be made on behalf of the Trust by you at the rate of
          $1,000 principal amount of Exchange Capital Securities
          for each $1,000 principal amount of the corresponding
          series of Original Capital Securities tendered promptly
          after notice (such notice if given orally, to be
          confirmed in writing) of acceptance of said Original
          Capital Securities by the Trust; provided, however, that
          in all cases, Original Capital Securities tendered
          pursuant to the Exchange Offer will be exchanged only
          after timely receipt by you of certificates for such
          Original Capital Securities (or confirmation of book-
          entry transfer into your account at the Book-Entry
          Transfer Facility), a properly completed and duly
          executed Letter of Transmittal (or facsimile thereof)
          with any required signature guarantees and any other
          required documents.  You shall issue Exchange Capital
          Securities only in denominations of $1,000 or any
          integral multiple thereof.  Original Capital Securities
          may be tendered in whole or in part in denominations of
          $100,000 and integral multiples of $1,000 in excess
          thereof, provided that if any Original Capital Securities
          are tendered for exchange in part, the untendered
          principal amount thereof must be $100,000 or any integral
          multiple of $1,000 in excess thereof.

               9.   Tenders pursuant to the Exchange Offer are
          irrevocable, except that, subject to the terms and upon
          the conditions set forth in the Prospectus and the Letter
          of Transmittal, Original Capital Securities tendered
          pursuant to the Exchange Offer may be withdrawn at any
          time on or prior to the Expiration Date.

               10.  The Trust shall not be required to exchange any
          Original Capital Securities tendered if any of the
          conditions set forth in the Exchange Offer are not met. 
          Notice of any decision by the Trust not to exchange any
          Original Capital Securities tendered shall be given
          orally (and confirmed in writing) or in writing by the
          Trust to you.

               11.  If, pursuant to the Exchange Offer, the Trust
          does not accept for exchange all or part of the Original
          Capital Securities tendered because of an invalid tender,
          the occurrence of certain other events set forth in the
          Prospectus under the caption "The Exchange Offer--
          Conditions to the Exchange Offer" or otherwise, you shall
          promptly after the expiration or termination of the
          Exchange Offer return those certificates for unaccepted
          Original Capital Securities (or effect appropriate book-
          entry transfer), together with any related required
          documents and the Letters of Transmittal relating thereto
          that are in your possession, to the persons who deposited
          them.

               12.  All certificates for reissued Original Capital
          Securities, unaccepted Original Capital Securities or for
          Exchange Capital Securities shall be forwarded by (a)
          first-class certified mail, return receipt requested,
          under a blanket surety bond protecting you and the Trust
          from loss or liability arising out of the non-receipt or
          non-delivery of such certificates, (b) by registered mail
          insured separately for the replacement value of each of
          such certificates, or (c) by appropriate book-entry
          transfer. 

               13.  You are not authorized to pay or offer to pay
          any concessions, commissions or solicitation fees to any
          broker, dealer, bank or other persons or to engage or
          utilize any person to solicit tenders.

               14.  As Exchange Agent hereunder you:

               (a) shall have no duties or obligations other than
          those specifically set forth in the section of the
          Prospectus captioned "The Exchange Offer," the Letter of
          Transmittal or herein or as may be subsequently agreed to
          in writing by you and the Trust;

               (b)  will be regarded as making no representations
          and having no responsibilities as to the validity,
          sufficiency, value or genuineness of any of the
          certificates or the Original Capital Securities
          represented thereby deposited with you pursuant to the
          Exchange Offer, and will not be required to and will make
          no representation as to the validity, value or
          genuineness of the Exchange Offer;

               (c)  shall not be obligated to take any legal action
          hereunder which might in your reasonable judgment involve
          any expense or liability, unless you shall have been
          furnished with reasonable indemnity; 

               (d)  may reasonably rely on and shall be protected
          in acting in reliance upon any certificate, instrument,
          opinion, notice, letter, telegram or other document or
          security delivered to you and reasonably believed by you
          to be genuine and to have been signed by the proper party
          or parties;

               (e)  may reasonably act upon any tender, statement,
          request, agreement or other instrument whatsoever not
          only as to its due execution and validity and
          effectiveness of its provisions, but also as to the truth
          and accuracy of any information contained therein, which
          you shall in good faith believe to be genuine or to have
          been signed or represented by a proper person or persons;

               (f)  may rely on and shall be protected in acting
          upon written or oral instructions from any Administrative
          Trustee of the Trust or from any Designated Officer of
          the Corporation;

               (g)  may consult with your counsel with respect to
          any questions relating to your duties and
          responsibilities and the advice or opinion of such
          counsel shall be full and complete authorization and
          protection in respect of any action taken, suffered or
          omitted to be taken by you hereunder in good faith and in
          accordance with the advice or opinion of such counsel;
          and

               (h)  shall not advise any person tendering Original
          Capital Securities pursuant to the Exchange Offer as to
          the wisdom of making such tender or as to the market
          value or decline or appreciation in market value of any
          Original Capital Securities.

               15.  You shall take such action as may from time to
          time be requested by the Trust or its counsel or any
          Designated Officer of the Corporation (and such other
          action as you may reasonably deem appropriate) to furnish
          copies of the Prospectus, Letter of Transmittal and the
          Notice of Guaranteed Delivery (as defined in the
          Prospectus) or such other forms as may be approved from
          time to time by the Trust or the Corporation, to all
          persons requesting such documents and to accept and
          comply with telephone requests for information relating
          to the Exchange Offer, provided that such information
          shall relate only to the procedures for accepting (or
          withdrawing from) the Exchange Offer.  The Trust will
          furnish you with copies of such documents at your
          request.  All other requests for information relating to
          the Exchange Offer shall be directed to the Trust,
          Attention: ___________.

               16.  You shall advise by facsimile transmission or
          telephone, and promptly thereafter confirm in writing to
          __________ of the Trust, and such other person or persons
          as the Trust or the Corporation may request, daily (and
          more frequently during the week immediately preceding the
          Expiration Date and if otherwise requested) up to and
          including the Expiration Date, as to the number of
          Original Capital Securities which have been tendered
          pursuant to the Exchange Offer and the items received by
          you pursuant to this Agreement, separately reporting and
          giving cumulative totals as to items properly received
          and items improperly received.  In addition, you will
          also inform, and cooperate in making available to, the
          Trust or the Corporation or any such other person or
          persons upon oral request made from time to time on or
          prior to the Expiration Date of such other information as
          it or such person reasonably requests.  Such cooperation
          shall include, without limitation, the granting by you to
          the Trust or the Corporation and such person as the Trust
          or the Corporation may request of access to those persons
          on your staff who are responsible for receiving tenders,
          in order to ensure that immediately prior to the
          Expiration Date the Trust or the Corporation shall have
          received information in sufficient detail to enable it to
          decide whether to extend the Exchange Offer.  You shall
          prepare a final list of all persons whose tenders were
          accepted, the aggregate principal amount of Original
          Capital Securities tendered, the aggregate principal
          amount of Original Capital Securities accepted and
          deliver said list to the Trust promptly after the
          Expiration Date.

               17.  Any Letters of Transmittal and Notices of
          Guaranteed Delivery which are received by the Exchange
          Agent shall be stamped by you as to the date and the time
          of receipt thereof and shall be preserved by you for a
          period of time at least equal to the period of time you
          preserve other records pertaining to the transfer of
          securities. You shall dispose of unused Letters of
          Transmittal and other surplus materials by returning them
          to the Trust at the address set forth below for notices.

               18.  You hereby expressly waive any lien,
          encumbrance or right of set-off whatsoever that you may
          have with respect to funds deposited with you for the
          payment of transfer taxes by reasons of amounts, if any,
          borrowed by the Trust, or any of its subsidiaries or
          affiliates pursuant to any loan or credit agreement with
          you or for compensation owed to you hereunder. 

               19.  For services rendered as Exchange Agent
          hereunder, you shall be entitled to such compensation as
          set forth on Schedule I attached hereto. 

               20.  You hereby acknowledge receipt of the
          Prospectus and the Letter of Transmittal and further
          acknowledge that you have examined each of them.  Any
          inconsistency between this Agreement, on the one hand,
          and the Prospectus and the Letter of Transmittal (as they
          may be amended from time to time), on the other hand,
          shall be resolved in favor of the latter two documents,
          except with respect to the duties, liabilities and
          indemnification of you as Exchange Agent, which shall be
          controlled by this Agreement. 

               21.  (a) The Trust covenants and agrees to indemnify
          and hold you harmless in your capacity as Exchange Agent
          hereunder against any loss, liability, cost or expense,
          including reasonable attorneys' fees and expenses,
          arising out of or in connection with any act, omission,
          delay or refusal made by you in reliance upon any
          signature, endorsement, assignment, certificate, order,
          request, notice, instruction or other instrument or
          document reasonably believed by you to be valid, genuine
          and sufficient and in accepting any tender or effecting
          any transfer of Original Capital Securities reasonably
          believed by you in good faith to be authorized, and in
          delaying or refusing in good faith to accept any tenders
          or effect any transfer of Original Capital Securities;
          provided, however, that the Trust shall not be liable for
          indemnification or otherwise for any loss, liability,
          cost or expense to the extent arising out of your
          negligence or misconduct.  In no case shall the Trust be
          liable under this indemnity with respect to any claim
          against you unless the Trust shall be notified by you, by
          letter or cable or by facsimile confirmed by letter, of
          the written assertion of a claim against you or of any
          other action commenced against you, promptly after you
          shall have received any such written assertion or notice
          of commencement of action.  The Trust shall be entitled
          to participate at its own expense in the defense of any
          such claim or other action, and, if the Trust so elects,
          the Trust may assume the defense of any suit brought to
          enforce any such claim.  In the event that the Trust
          shall assume the defense of any such suit or threatened
          action in respect of which indemnification may be sought
          hereunder, the Trust shall not be liable for the fees and
          expenses of any additional counsel thereafter retained by
          you so long as you consent to the Trust's retention of
          counsel, which consent may not be unreasonably withheld;
          provided that the Trust shall not be entitled to assume
          the defense of any such action if the named parties to
          such action include both the Trust and you and
          representation of both parties by the same legal counsel
          would, in the written opinion of counsel to you, be
          inappropriate due to actual or potential conflicting
          interests between you and the Trust.  It is understood
          that the Trust shall not be liable under this paragraph
          for the fees and expenses of more than one legal counsel
          for you.  In the event that the Trust shall assume the
          defense of any such suit, the Trust shall not thereafter
          be liable for the fees and expenses of any counsel
          retained by you.

               (b)  You agree that, without the prior written
          consent of the Trust, you will not settle, compromise or
          consent to the entry of any pending or threatened claim,
          action or proceeding in respect of which indemnification
          could be sought in accordance with the indemnification
          provisions of this Agreement (whether or not you or the
          Trust or any of its trustees, or controlling persons is
          an actual or potential party to such claim, action or
          proceeding), unless such settlement, compromise or
          consent includes an unconditional release of the Trust
          and its trustees and controlling persons from all
          liability arising out of such claim, action or
          proceeding.

               22.  You shall arrange to comply with all
          requirements under the tax laws of the United States,
          including those relating to missing Tax Identification
          Numbers, and shall file any appropriate reports with the
          Internal Revenue Service.  The Trust understands that you
          are required in certain instances to deduct 31% with
          respect to interest paid on the Exchange Capital
          Securities and proceeds from the sale, exchange,
          redemption or retirement of the Exchange Capital
          Securities from holders who have not supplied their
          correct Taxpayer Identification Number or required
          certification.  Such funds will be turned over to the
          Internal Revenue Service in accordance with applicable
          regulations.

               23.  You shall notify the Trust of the amount of any
          transfer taxes payable in respect of the exchange of
          Original Capital Securities and, upon receipt of written
          approval from the Trust, you shall deliver or cause to be
          delivered, in a timely manner to each governmental
          authority to which any transfer taxes are payable in
          respect of the exchange of Original Capital Securities,
          your check in the amount of all transfer taxes so
          payable, and the Trust shall reimburse you for the amount
          of any and all transfer taxes payable in respect of the
          exchange of Original Capital Securities; provided,
          however, that you shall reimburse the Trust for amounts
          refunded to you in respect of your payment of any such
          transfer taxes, at such time as such refund is received
          by you. 

               24.  This Agreement and your appointment as Exchange
          Agent hereunder shall be construed and enforced in
          accordance with the laws of the State of New York
          applicable to agreements made and to be performed
          entirely within such state, and without regard to
          conflicts of law principles, and shall inure to the
          benefit of, and the obligations created hereby shall be
          binding upon, the successors and assigns of each of the
          parties hereto. 

               25.  This Agreement may be executed in one or more
          counterparts, each of which shall be deemed to be an
          original and all of which taken together shall constitute
          one and the same agreement.

               26.  In case any provision of this Agreement shall
          be invalid, illegal or unenforceable, the validity,
          legality and enforceability of the remaining provisions
          shall not in any way be affected or impaired thereby. 

               27.  This Agreement shall not be deemed or construed
          to be modified, amended, rescinded, canceled or waived,
          in whole or in part, except by a written instrument
          signed by a duly authorized representative of the party
          to be charged.  This Agreement may not be modified
          orally. 

               28.  Unless otherwise provided herein, all notices,
          requests and other communications to any party hereunder
          shall be in writing (including facsimile or similar
