(1) This Registration Statement relates to the common shares, par value $.10 per
    share, of the Registrant estimated to be issuable in connection with the
    business combination.

(2) The number of Trenwick Group Ltd. common shares to be registered pursuant to
    this Registration Statement is based on the maximum number of Trenwick Group
    Ltd. common shares estimated to be issuable to holders of Trenwick common
    stock, LaSalle Re Holdings Limited common shares and LaSalle Re Limited
    exchangeable non-voting common shares upon the effectiveness of the business
    combination under the terms of the business combination agreement which
    represents that number of shares of Trenwick common stock, LaSalle common
    shares and LaSalle Re exchangeable non-voting common shares (other than
    those owned by LaSalle), expected to be outstanding immediately prior to the
    effective time of the business combination, multiplied by the exchange ratio
    of one Trenwick Group Ltd. common share for each share of Trenwick common
    stock, LaSalle common share and LaSalle Re exchangeable non-voting common
    share.

(3) The estimated registration fees have been computed pursuant to Rule
    457(f)(1) and 457(c) under the Securities Act and estimated solely for the
    purpose of calculating the registration fee, the proposed maximum aggregate
    offering price is equal to the sum of (a) the product of (x) $19.6875, the
    average of the high and low sales prices per share of Trenwick common stock
    on the New York Stock Exchange, Inc. Composite Transaction Tape on August
    17, 2000, multiplied by (y) 16,288,082, the total number of shares of
    Trenwick common stock to be exchanged pursuant to the terms of the business
    combination agreement and (b) the product of (x) $18.9375, the average of
    the high and low sales prices per share of LaSalle common shares on the New
    York Stock Exchange, Inc. Composite Transaction Tape on August 17, 2000,
    multiplied by (y) 20,455,385, the total number of LaSalle common shares and
    LaSalle Re exchangeable non-voting common shares to be exchanged pursuant to
    the terms of the business combination agreement.

(4) This fee has been calculated pursuant to Rule 457(f) under the Securities
    Act as .0264 of one percent of $708,045,467.80, the proposed maximum
    aggregate offering price. Pursuant to Rule 457(b) under the Securities Act,
    the amount of the registration fee has been reduced by $103,787.51, the
    amounts paid to the Securities and Exchange Commission on July 5, 2000
    ($6,545.92), May 17, 2000 ($9,456.25) and March 20, 2000 ($87,785.34) with
    respect to this transaction. The difference of $83,136.49 is being paid
    herewith.

(5) Includes associated Rights to purchase one one-hundredth of a share of
    Trenwick Group Ltd. Series A First Preference Shares, par value $.10 per
    share. Until the occurrence of certain prescribed events, the Rights are not
    exercisable. The Rights are evidenced by the certificates representing
    Trenwick Group Ltd. common shares and will be transferred only with such
    shares.
                            ------------------------
    THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL

STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933, AS AMENDED, OR UNTIL THIS REGISTRATION STATEMENT
SHALL BECOME EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID
SECTION 8(a), MAY DETERMINE.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under Bermuda law, a company is permitted to indemnify any officer or
director, out of the funds of the company against (a) any liability incurred by
him or her in defending any proceedings, whether civil or criminal, in which
judgment is given in his or her favor, or in which he or she is acquitted, or in
connection with any application under relevant Bermuda legislation in which
relief from liability is granted to him or her by the court and (b) any loss or
liability resulting from negligence, default, breach of duty or breach of trust,
save for his or her fraud and dishonesty.

     The Bye-laws of Trenwick Group Ltd. provide for the indemnity of its
officers and directors as well as their heirs, executors and administrators to
the fullest extent permitted by law. Bermuda law does not permit indemnification
of a person who is or may be found guilty of fraud or dishonesty.

     The Bye-laws of Trenwick Group Ltd. also provide that all reasonable
expenses (including attorneys' fees) incurred by or on behalf of an officer or
director of Trenwick Group Ltd. in defending any civil, criminal, administrative
or investigative action, suit or proceeding shall be paid by Trenwick Group Ltd.
in advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such director or officer to repay
such amount if it shall ultimately be determined that he or she is not entitled
to be indemnified by Trenwick Group Ltd. pursuant to Bermuda law.

     The Bye-laws of Trenwick Group Ltd. also provide that an officer or
director of Trenwick Group Ltd. shall not be personally liable to Trenwick Group
Ltd. or its shareholders for monetary damages for any breach of fiduciary duty
as a director or officer, except to the extent that such limitation is
prohibited by Bermuda law.

ITEM 22.  UNDERTAKINGS.

     (a) 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 the 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 Securities and Exchange Commission pursuant to Rule 424(b) if,
        in the aggregate, the changes in volume and price represent no more than
        a 20 percent change in the maximum aggregate offering price set forth in
        the effective Registration Statement; and

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the 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.

          (4) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

          (5) That every prospectus: (i) that is filed pursuant to paragraph (4)
     immediately preceding, or (ii) that purports to meet the requirements of
     Section 10(a)(3) of the Act and is used in connection with an offering of
     securities subject to Rule 415, will be filed as a part of an amendment to
     the Registration Statement and will not be used until such amendment is
     effective, and that, for purposes 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.

     (b) 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 foregoing provisions, 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

                                      II-3
   5

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 controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

     (c) The undersigned Registrant hereby undertakes 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.

     (d) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                                      II-4
