The Company'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, 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.

The Company's principal executive offices are located at One State Street, Hartford, Connecticut 06102. The Company's telephone number is (860) 722-1866. USE OF PROCEEDS The Company will not receive any of the proceeds of sales of Common Stock by the Selling Shareholders. SELLING SHAREHOLDERS The Company issued shares of Common Stock, as shown in the following table, to the Selling Shareholders on April 28, 1998 in connection with the merger (the "Merger") of SAI Acquisition Corporation, a Texas corporation and wholly owned subsidiary of the Company with and into Solomon Associates, Inc., whereby Solomon Associates, Inc. became a wholly owned subsidiary of the Company. In connection with the Merger, the shareholders of Solomon Associates, Inc. received the number of shares of the Company as shown in the following table (the "Shares"), which represent all of the Common Stock presently owned by the Selling Shareholders, and which in each shareholder's case represents less than 1% of the Company's Common Stock outstanding as of the date of this Prospectus. Name Number of shares - ----- ---------------- Lawrence D. Nieman 10,158 Solomon Enterprises, Ltd. 102,751 SAI Management Trust 92,265 Under the terms of the merger agreement dated April 20, 1998 by and among the Company, SAI Acquisition Corporation, Solomon Associates, Inc., Lee H. Solomon and the shareholders of Solomon Associates, Inc. (the "Merger Agreement"), the Company agreed to use its best efforts to file a registration statement with respect to the Shares and to maintain the effectiveness of such registration statement for a period of one year from the date of delivery of the Shares to the Selling Shareholders. PLAN OF DISTRIBUTION Shares of the Company's Common Stock may be sold pursuant to this Prospectus from time to time by the Selling Shareholders. Such sales may be made from time to time on the New York Stock Exchange or such other national securities exchange or automated interdealer quotation system on which shares of Common Stock are then listed, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The shares may be sold by (i) a block trade in which the broker or dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction; (ii) purchases by a broker or dealer as principal and resale by such broker or dealer for its account; and (iii) ordinary brokerage transactions and transactions in which the broker solicits purchasers. In effecting sales, brokers or dealers engaged by the Selling Shareholders may arrange for other brokers or dealers to participate. Brokers or dealers will receive commissions or discounts from the Selling Shareholders in amounts to be negotiated immediately prior to the sale. Such brokers or dealers may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In addition, any shares which qualify for sale under Rule 144 or Rule 144A under the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this Prospectus. The Company has been advised that, as of the date hereof, the Selling Shareholders have made no arrangement with any broker for the sale of their shares of Common Stock. The Selling Shareholders and any underwriters, brokers or dealers involved in the sale of the Securities may be considered "underwriters" as that term is defined by the Securities Act of 1933. Under the Merger Agreement, the Company has agreed to indemnify the Selling Shareholders and any other person who participates in the offering or sale of the Shares on behalf of the Selling Shareholders against certain liabilities which may be incurred in connection with the sale of the Shares under this Prospectus. At the time a particular offering of any Shares is made hereunder, to the extent required by law, a Prospectus Supplement will be distributed which will set forth the amount of Shares being offered and the terms of the offering, including the purchase price or public offering price, the name or names of any underwriters, dealers or agents, the purchase price paid by any underwriter for any Shares purchased from the Selling Shareholders, any discounts, commissions and other items constituting compensation from the Selling Shareholders and any discounts, commissions or concessions allowed or filed or paid to dealers. In order to comply with the securities laws of certain states, if applicable, the Shares will be sold hereunder in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the Securities may not be sold hereunder unless the Securities have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with. LEGAL MATTERS The validity of the Shares has been passed upon for the Company by Robert C. Walker, Esquire, Senior Vice President and General Counsel to the Company. Mr. Walker's current holdings in Registrant common stock consist of the following: 4,850 shares held directly, approximately 605 shares held through the Registrant's Thrift Incentive Plan and approximately 103 shares held through the Registrant's Employee Stock Ownership Plan, and 80,000 presently exercisable stock options. PART II INFORMATION NOT REQUIRED IN THE PROSPECTUS ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION The following table sets forth the estimated expenses in connection with the issuance and distribution of the securities being registered, other than underwriting discounts and commissions: Registration fee - Securities and Exchange Commission $4,055 Miscellaneous $1,000 Total $5,055 ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. HSB Group's Articles of Incorporation provide that the Company 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 the Company's Articles of Incorporation. As permitted by the CBCA, the Company will continue to secure insurance which provides broader indemnification of directors than is required under the CBCA. ITEM 16.

Walker, Senior Vice President and General Counsel 23 Consent of Coopers & Lybrand, L.L.P. Consent of Robert C. Walker (included in Exhibit 5) 24 Power of Attorney ITEM 17. UNDERTAKINGS The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (Section 230.424(b) of 17 C.F.R.) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii)To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under Item 15 above, or otherwise, the 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 the Registrant of expenses incurred or paid by a director, officer or controlling person of the 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, the 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 Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Hartford, in the State of Connecticut, on the 18th of May, 1998.
