     as of December 30, 1994, by and between The Hartford Steam
     Boiler Inspection and Insurance Company, a Connecticut
     corporation ("Hartford"), and General Reinsurance Corpora-
     tion, a Delaware corporation ("GenRe").
     
               Hartford and GenRe currently each hold a 50%
     general partnership interest in Engineering Insurance
     Group, a Connecticut partnership (the "Partnership"). 
     Hartford and GenRe desire to exchange their interests
     (each an "Interest") in the Partnership for stock of EIG,
     Co., a newly formed Delaware corporation ("Newco"), on the
     terms hereinafter set forth.
     
               In order to implement the foregoing and in
     consideration of the mutual representations, warranties,
     covenants and agreements contained herein, the parties
     hereto agree as follows:
     
     1.   Transaction.
     
               1.1.  Formation of Newco.  Upon the terms and
     subject to the conditions set forth in this Agreement,
     Hartford, in reliance upon the representations, warranties
     and agreements contained herein, hereby agrees to transfer
     all of its Interest in the Partnership, on the Closing
     Date (as defined below), to Newco in exchange for 200
     shares of common stock of Newco, per value $.01 per share
     (the "Newco Common Stock").  At the Closing (as defined
     below), Hartford shall also acquire 35 additional shares
     of Newco Common Stock for $3.5 million in cash.
     
               1.2.  Exchange.  Upon the terms and subject to
     the conditions set forth in this Agreement, GenRe, in
     reliance upon the representations, warranties and agree-
     ments contained herein, hereby agrees to transfer all of
     its Interest in the Partnership, on the Closing Date (as
     defined in Section 1.3 below), to Newco in exchange for
     2,000 shares of Series A Cumulative Preferred Stock of
     Newco having the terms and preferences set forth in Exhib-

               1.3.  The Closing.  The closing (the "Closing")
     of the transactions contemplated by Sections 1.1 and 1.2
     shall take place on December 30, 1994 or as soon thereaf-
     ter as is practicable.  On the date the Closing occurs
     (the "Closing Date"), GenRe shall transfer its Interest to
     Newco and Newco shall deliver GenRe a certificate or
     certificates registered in GenRe's name representing the
     Newco Preferred Stock.  On the Closing Date, Hartford
     shall transfer its Interest to Newco and Newco shall
     deliver to Hartford a certificate or certificates regis-
     tered in Hartford's name representing the Newco Common
     Stock.
     
     2.   Further Agreements.
     
               2.1. Keepwell.  Hartford hereby agrees, for the
     express benefit of GenRe (and not for the benefit of any
     person not a party hereto), to provide Newco with suffi-
     cient funds to pay any debt or equity obligation of Newco
     upon maturity or redemption, as the case may be (by accel-
     eration or otherwise), and to pay dividends on the Newco
     Preferred Stock as such dividends become due.  Hartford
     further agrees that it will cause the Board of Directors
     of Newco to declare and pay dividends on the Newco Pre-
     ferred Stock for each and every "Dividend Period" (as that
     term is defined in Exhibit A), subject to the requirements
     of applicable law.
     
               2.2.  Call.  Hartford, at any time within a
     twenty-business day period commencing on the second anni-
     versary of the Closing, may elect to exchange 2,000 shares
     of Series B Convertible Preferred Stock of Hartford to be
     issued pursuant to a certificate of designation in the
     form of Exhibit B hereto (the "Hartford Preferred Stock")
     for the Newco Preferred Stock, such shares of Newco Pre-
     ferred Stock to be duly issued, fully paid and nonassess-
     able and such exchange to be consummated as promptly as
     practicable after such election.
     
               2.3.  Put.  GenRe, at any time within a twenty-
     business day period commencing on the fifth anniversary of
     the Closing, may elect to exchange the Newco Preferred
     Stock for 2,000 shares of Hartford Preferred Stock, such
     shares to be duly issued, fully paid and nonassessable and
     such exchange to be consummated as promptly as practicable
     after such election.
     
               2.4.  Financial Statements.  Promptly after the
     Closing Date, Hartford will cause Newco to prepare finan-
     cial statements of Newco as of the Closing Date.  Such
     financial statements will be delivered to Hartford and
     GenRe.
     
     3.  Representations, Warranties and Agreements of 
     Hartford.  Hartford represents and warrants to GenRe as
     follows:
     
                    (a)  Hartford has all requisite corporate
     power and authority to enter into, execute, deliver and
     consummate the transactions contemplated by this Agreement
     and this Agreement has been duly authorized, executed and
     delivered by Hartford and is a valid and binding obli-
     gation of Hartford enforceable against Hartford in accor-
     dance with its terms;
     
                    (b)  the Hartford Preferred Stock, when

     sessable;
     
                    (c)  neither the execution and delivery by
     Hartford of this Agreement nor the consummation by Hart-
     ford of the transactions contemplated hereby will violate
     any provision of the Charter (as in effect at the Closing)
     or By-Laws of Hartford, any law or regulation applicable
     to Hartford or to which its properties are subject or
     result in any material breach of any terms or provisions
     of, or constitute a material default under, any material

     party or by which Hartford is bound;
     
                    (d)  Hartford has not entered into any

     shares of Common Stock, of which approximately 20,500,000
     shares were issued and outstanding as of September 30,
     1994, and 500,000 shares of Preferred Stock, without par
     value, of which a series of the Company's Preferred Stock
     known as the Series A Preferred Stock has been authorized
     and of which no shares are outstanding and of which a
     series of the Company's Preferred Stock known as the
     Series B Preferred Stock has been created and of which no

     purchase of, or any agreements, providing for the issuance
     (contingent or otherwise) of, or any calls, commitments or
     claims of any character relating to, any shares of capital
     stock or any securities convertible into or exchangeable

     from Hartford good and marketable title to the Interest
     currently held by Hartford, free and clear of any lien,
     charge, claim, pledge, option, encumbrance or other rights
     of third parties.

     5.   Investment Representations; Transfer Restriction.
     
               5.1.  Investment Intention; No Resales.  GenRe,
     with respect to all of the shares of Newco Preferred Stock
     to be acquired by it hereunder (or shares of Hartford
     Preferred Stock issuable upon exchange thereof), and Hart-
     ford, with respect to the Newco Common Stock to be ac-
     quired by it hereunder, each represents and warrants that
     it is acquiring such shares for investment solely for its
     own account and not with a view to, or for resale in
     connection with, the distribution thereof and not with a
     present intention of distribution.  Each such party agrees
     and acknowledges (to the other and for the benefit of
     Newco) that, it will not, directly or indirectly, offer,
     transfer, sell, assign, pledge, hypothecate or otherwise
     dispose of any of such shares, or solicit any offers to
     purchase or otherwise acquire or take a pledge of any of
     such shares, unless such offer, transfer, sale, assign-
     ment, pledge, hypothecation or other disposition is pursu-
     ant to an effective registration statement under the
     Securities Act of 1933, as amended (the "Act"), and has
     been registered under all applicable state securities and
     "blue sky" laws or such party shall have furnished Newco
     (or, in the case of Hartford Preferred Stock, Hartford)
     with an opinion of counsel, which opinion and counsel
     shall be reasonably satisfactory to Newco (or, in the case
     of Hartford Preferred Stock, Hartford), to the effect that
     no such registration is required because of the availabil-
     ity of an exemption from registration under the Act and
     all applicable state securities and "blue sky" laws.
     
               5.2.  Federal Securities Laws Matters.  Each of
     GenRe and Hartford hereby further represents and warrants
     to the other and for the benefit of Newco that it is
     familiar with Release No. 5226 issued by the Securities
     and Exchange Commission under the Act, it has consulted
     with its counsel with regard thereto, and it is fully
     aware of the position of the Commission limiting the
     resale to the public of any shares of Newco Preferred
     Stock, Hartford Preferred Stock or Newco Common Stock.
     
               5.3.  Additional Investment Representations.
     Each of GenRe and Hartford hereby further represents and
     warrants to the other and for the benefit of Newco that
     either (i) it is an "Accredited Investor" (as such term is
     defined in Rule 501 of Regulation D under the Act) or (ii)
     (A) its financial situation is such that it can afford to
     bear the economic risk of holding the shares of Newco
     Preferred Stock, Hartford Preferred Stock or Newco Common
     Stock for an indefinite period of time, (B) it can afford
     to suffer complete loss of its investment in the shares of
     Newco Preferred Stock, Hartford Preferred Stock or Newco
     Common Stock, and (C) its knowledge and experience in
     financial and business matters are such that it is capable
     of evaluating the merits and risks of investment in the
     shares of Newco Preferred Stock, Hartford Preferred Stock
     or Newco Common Stock.
     
               5.4.  Transfer Restriction; Certain Permitted
     Transfers.  GenRe shall not transfer the shares of Newco
     Preferred Stock at any time prior to the second anniversa-
     ry of the Closing Date (the "Second Anniversary") without
     the prior written consent of Hartford, which consent may
     be withheld in Hartford's sole discretion.  Hartford shall
     not transfer the shares of Newco Common Stock acquired
     hereunder at any time prior to the Second Anniversary
     without the prior written consent of GenRe, which consent
     may be withheld in GenRe's sole discretion.  The certifi-
     cates with respect to the shares of Newco Common Stock or
     Newco Preferred Stock acquired hereunder will contain a
     legend which shall refer to this restriction.  Anything to
     the contrary in this Agreement notwithstanding, each of
     GenRe and Hartford may transfer any of its shares of Newco
     Preferred Stock, Hartford Preferred Stock or Newco Common
     Stock to any subsidiary of such party who is an Accredited
     Investor, and no opinion of counsel as to the availability
     of an exemption under the Act is required in connection
     therewith.
     
     6.   Conditions to Obligations of GenRe.
     
               The obligation of GenRe hereunder is subject to
