ITEM 5.  OTHER EVENTS.
 
     On March 31, 1999, the Company sold to certain existing shareholders of the
Company an aggregate of 43,997,863 shares of Series C Convertible Cumulative
Voting Preferred Stock, par value $.01 per share, of the Company (the "Series C
Preferred Stock") for net cash proceeds of $50,996,794.50. The sale was made
pursuant to the terms of the Series C Convertible Cumulative Voting Preferred
Stock Subscription Agreement (the "Series C Preferred Stock Subscription
Agreement") which is filed as Exhibit 4.1 to this Report. Pursuant to the terms
of the Series C Preferred Stock Subscription Agreement, 31,997,863 shares of
Series C Preferred Stock were sold at $1.50 per share pursuant to the basic
subscription privilege (and overallotments with respect thereto) and 12,000,000
shares of Series C Preferred Stock were sold at $0.25 per share pursuant to the
additional allotment privilege (and overallotments with respect thereto). Shares
of Series C Preferred Stock may be converted into shares of common stock, par
value $.01 per share, of the Company (the "Common Stock") on a one-for-one basis
at the holder's option at any time, and are mandatorily convertible into shares
of Common Stock on a one-for-one basis upon the occurrence of certain events.
The net proceeds from the transaction will be used for general corporate
purposes and to make capital investments in the Company's wholly owned
subsidiary, Commercial Guaranty Assurance, Ltd.
 
     In connection with the consummation of the transactions contemplated by the
Series C Preferred Stock Subscription Agreement, on March 31, 1999, all issued
and outstanding shares of Series B Cumulative Voting Preferred Stock, par value
$.01 per share, of the Company (the "Series B Preferred Stock") were converted
into shares of Common Stock, at a conversion ratio of 11.816 shares of Common
Stock per share of Series B Preferred Stock. The conversion ratio was based on
an assumed value of $3.00 per share of Common Stock. As a result of the
conversion, 18,905,648 new shares of Common Stock were issued.
 
     The Company has amended its Bye-laws (including the Appendices thereto) as
of March 31, 1999, to reflect the new capital structure of the Company as a
result of the consummation of the transactions described above. The Amended and
Restated Bye-laws of the Company and the amended Appendices thereto are filed as
Exhibits 4.2 and 4.3, respectively, to this Report.
 
     The Company, the holders of the Common Stock and the holders of the Series
C Preferred Stock have entered into the Shareholders Agreement, dated as of June
12, 1997, as amended and restated as of March 31, 1999 (the "Amended and
Restated Shareholders Agreement"), to reflect the new capital structure of the
Company as a result of the consummation of the transactions described above, and
to add the new holders of Series C Preferred Stock as parties thereto with
respect to the shares of Series C Preferred Stock. The Amended and Restated
Shareholders Agreement is filed as Exhibit 4.4 to this Report.

                SERIES C CUMULATIVE CONVERTIBLE PREFERRED STOCK
                             SUBSCRIPTION AGREEMENT
 
     SUBSCRIPTION AGREEMENT, dated as of March 1, 1999 (this "Agreement"), among
CGA Group, Ltd., a company with limited liability organized under the laws of
Bermuda (together with its successors and permitted assigns, the "Company"), and
each of the Investors identified in Schedule I hereto (collectively, together
with their successors and permitted assigns, the "Investors").
 
     WHEREAS, the Company has distributed subscription rights (the "Rights") to
subscribe for shares of the Series C Cumulative Convertible Preferred Stock, par
value U.S. $.01 per share (the "Series C Preferred Stock") to the Investors
pursuant to an Offering Circular, dated January 21, 1999 as supplemented on
February 5, 1999, February 12, 1999 and February 22, 1999 (together with any
amendments, modifications or supplements thereto as may be made from time to
time on or prior to the Closing Date (as defined below), the "Offering
Circular");
 
     WHEREAS, the Investors understand that the voting power of their aggregate
ownership of voting securities of the company is subject to the Maximum
Percentage limitation contained in Bye-laws 1(cc) and 50 of the Company's
Amended and Restated Bye-laws (as defined herein), and as a result the voting
power of some shares of Series C Preferred Stock may be reduced in accordance
with the terms of the Bye-laws as described in the "Description of Securities"
contained in the Offering Circular; and
 
     WHEREAS, each of the Investors wishes to subscribe for and purchase,
severally and not jointly, and the Company wishes to issue and sell to each
Investor the number of shares of Series C Preferred Stock applicable to each
Investor set forth opposite such Investor's name on Schedule I hereto, on the
terms set forth herein.
 
     NOW THEREFORE, in consideration of the premises and mutual agreements
herein contained, the parties hereto hereby agree as follows:
 
                                   ARTICLE 1
 
            AUTHORIZATION; SUBSCRIPTION FOR SERIES C PREFERRED STOCK
 
     SECTION 1.1  The Series C Preferred Stock.  The Company has authorized the
issuance and sale pursuant to this Agreement of up to 52,000,000 shares of
Series C Preferred Stock having such rights, restrictions and privileges as are
contained in or accorded by (i) the Memorandum of Association of the Company in
the form attached hereto as Annex I (the "Memorandum of Association"), (ii) the
Amended and Restated Bye-laws of the Company, in the form attached hereto as
Annex II and all appendices and exhibits thereto (the "Amended and Restated
Bye-Laws"), (iii) the Amended and Restated Shareholders Agreement, to be dated
as of the Closing Date, among the Company, the Investors and the other parties
named therein, in the form attached hereto as Annex III (as such agreement may
be amended, supplemented, restated or otherwise modified from time to time in
accordance with its terms, the "Amended and Restated Shareholders Agreement"),
and (iv) this Agreement. Subject to the terms and conditions hereof, the
Preferred Stock will be issued on the Closing Date.
 
     SECTION 1.2  Subscription for Series C Preferred Stock.  (a) Subject to the
terms and conditions of this Agreement, each of the Investors hereby irrevocably
subscribes for and agrees to purchase, severally and not jointly, the aggregate
number of shares of Series C Preferred Stock set forth below such Investor's
name on the signature page hereto for the purchase price specified in Article 2
hereof. Such aggregate number is comprised of (i) the number of shares of Series
C Preferred Stock which such Investor is entitled to purchase upon exercise of
the Rights distributed to such Investor pursuant to the Offering Circular (the
"Basic Subscription"), (ii) such number of additional shares of Series C
Preferred Stock which the Investor requests to purchase pursuant to the Front
End Additional Allotment Privilege (as defined below), (iii) such number of
additional shares of Series C Preferred Stock which the Investor requests to
purchase pursuant to the Back End Oversubscription Privilege (as defined below)
set forth in the Offering Circular and (iv) such number of additional shares of
Series C Preferred Stock which the Investor requests to purchase pursuant to the
<PAGE>   6
 
Additional Back End Privilege (as defined below) set forth in the Offering
Circular. The Investors acknowledge that the Company may actually issue and sell
to each Investor at the Closing fewer than the number of shares of Series C
Preferred Stock set forth below each Investor's name on its signature page
hereto, based upon the calculations of oversubscriptions and additional
allotments as set forth in this Agreement.
 
     (b) In the event that the Company receives from the Investors subscriptions
to purchase at least U.S. $47 million in Series C Preferred Stock in the
aggregate at U.S. $1.50 per share pursuant to the Basic Subscription Privilege
and the Back End Oversubscription Privilege (as defined below), then those
Investors who fully exercise all Rights allotted to them pursuant to the Basic
Subscription Privilege will be entitled to purchase a portion of 12,000,000
additional shares of Series C Preferred Stock (the "Additional Shares") at a
price (the "Additional Allotment Price") of U.S. $0.25 per share (the "Front End
Additional Allotment Privilege"). The purchase by an Investor of its full
allotted number of shares pursuant to its Basic Subscription Privilege plus its
full allotted number of shares pursuant to its Front End Additional Allotment
Privilege is defined as such Investor's "Front End Purchase" and the average
price per share paid by such Investor for all such shares is defined as such
Investor's "Front End Share Price." The number of Additional Shares that each
Investor will be entitled to purchase at the Additional Allotment Price as part
of its Front End Purchase (a) will be contingent upon the dollar amount of the
Aggregate Basic Subscription (as defined below) and the resulting calculation of
Additional Back End Shares, as described below and (b) will equal a fraction
(the numerator of which will be the number of shares purchased pursuant to such
Investor's Basic Subscription Privilege and the denominator of which will be the
total number of shares purchased by all Investors who have fully exercised all
Rights allotted to them pursuant to the Basic Subscription Privilege) of the
number of shares equal to 12,000,000 minus the aggregate number of Additional
Back End Shares (as defined below) purchased by all Investors.
 
     (c) If the aggregate purchase price of the shares subscribed for by all
Investors in the aggregate pursuant to the Basic Subscription Privilege (the
"Aggregate Basic Subscription") is less than U.S. $47 million, then those
Investors who fully exercise all Rights allotted to them pursuant to the Basic
Subscription Privilege will be entitled, as a group, to purchase a number of
shares of Series C Preferred Stock, at U.S. $1.50 per share (the "Back End
Oversubscription Shares"), equal to the difference between U.S. $47 million and
the Aggregate Basic Subscription (the "Back End Oversubscription Privilege").
Each such Investor shall be entitled to purchase a percentage of the Back End
Oversubscription Shares equal to a fraction, the numerator of which is the total
number of shares purchased by such Investor pursuant to its Basic Subscription
Privilege, and the denominator of which is the total number of shares purchased
by all Investors who have fully exercised all Rights allotted to them pursuant
to the Basic Subscription Privilege. Any unsubscribed-for Back End
Oversubscription Shares will be offered to those Investors who have elected to
purchase their own full allotment of Back End Oversubscription Shares, pro rata
based on the number of shares constituting such elections.
 
     (d) Each Investor that elects to purchase Back End Oversubscription Shares
will also be entitled to purchase a number of Additional Shares (the "Additional
Back End Shares"), at the Additional Allotment Price of U.S. $0.25 per share
(the "Additional Back End Privilege"), such that the average price per share of
such Investor's Back End Oversubscription Shares and Additional Back End Shares,
taken as a whole, shall be 80% of the Front End Share Price.
 
     (e) Based upon (i) the number of shares of Series C Preferred Stock which
an Investor subscribes for pursuant to the Basic Subscription Privilege, the
Front End Additional Allotment Privilege, the Back End Oversubscription
Privilege and the Additional Back End Privilege such number being determined
after all prorations described above have been effected, the number of shares of
Series C Preferred Stock issuable to each Investor shall be determined as soon
as practicable thereafter.
 
     (f) For purposes of this Agreement, Maximum Percentage shall have the
meaning assigned to it in Bye-laws 1(cc) and 50 of the Amended and Restated
Bye-laws. In the event that the issuance of Series C
 
                                        2
<PAGE>   7
 
Preferred Stock upon exercise of Rights would cause an Investor's ownership of
voting stock of the Company to exceed the Maximum Percentage, the voting power
of such Investors' Series C Preferred Stock shall be reduced pursuant to the
terms and conditions set forth in the Bye-laws and described in the Offering
Circular, so that such Investor will not violate the Maximum Percentage
limitation.
 
     (g) No Investor shall be obligated to purchase any shares of Series C
Preferred Stock unless the conditions set forth in Article 3 hereof shall have

     five business days prior written notice, delivered by facsimile, to the

of the date of this Agreement and as of the Closing Date as follows:
 
     SECTION 5.1  Due Organization, Valid Existence and Authority of the Company
and the Company's Initial Subsidiaries.  (a) The Company has been duly

of the Closing, the Company will have full right, power and authority to carry
on its business as conducted and as proposed to be conducted as described in the
Offering Circular. The Company has full right, power and authority to enter into
this Agreement, and perform its obligations hereunder. The Memorandum of
Association, in the form attached hereto as Annex I, is a true and complete copy
of the Memorandum of Association of the Company as in effect at the date of this

the Company will not own any interest in or control, directly or indirectly, any
other corporations, partnerships or other entities, other than the Initial

<PAGE>   10
 
     (b) Each of the Initial Subsidiaries has been duly incorporated and is
validly existing under the laws of its jurisdiction of incorporation. Upon
completion of the Closing and the use of the proceeds therefrom as described in
the Offering Circular, each Initial Subsidiary will have the full right, power
and authority to carry on its business as proposed to be conducted as described
in the Offering Circular (including the documents incorporated therein by
reference).
 
     SECTION 5.2  Authorization and Validity of Agreements.  This Agreement has
been duly authorized, executed and delivered by the Company and constitutes a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally and subject, as to enforceability, to
general principles of equity, including principles of commercial reasonableness,

proceeding at law or in equity) (together, the "Creditor and Enforceability
Exceptions").
 
     SECTION 5.3  Capitalization.  The sale of the Series C Preferred Stock and
the issuance of the shares have been duly authorized by the Company and, upon
payment for the Series C Preferred Stock in accordance with Article 2 hereof,
the shares issued at Closing will be validly issued, fully paid and
non-assessable (meaning that no further sums will be payable in respect of the
holding of the Shares). Except as described in the Offering Circular (including
the documents incorporated therein by reference), the Company does not, and on
the Closing Date will not, have any outstanding or authorized options, warrants,
calls, rights or any other agreements of any character obligating it to issue
any of its shares or any securities convertible into or exchangeable for, or
evidencing the right to purchase or obtain, any of its shares or any agreements
or understandings with respect to the voting, sale or transfer of any of its
shares or any securities convertible into or exchangeable for or evidencing the
right to purchase or obtain any of its shares.
 
     SECTION 5.4  No Conflict with Other Instruments; No Approvals Required
Except as Have Been Obtained.  The execution and delivery of this Agreement by
the Company and compliance by the Company with the terms and conditions hereof,
will not violate, with or without the giving of notice or the lapse of time, or
both, or require any registration, qualification, approval or filing under, any
provision of law, statute, ordinance or regulation applicable to the Company or
any affiliate thereof, and will not conflict with, or require any consent or
approval under, or result in the breach or termination of any provision of, or
constitute a default under, or result in the acceleration of the performance of
the obligations of the Company or any affiliate thereof under, or result in the
creation of any claim, lien, charge or encumbrance upon any of the properties,
assets or businesses of the Company or any affiliate thereof pursuant to the
Memorandum of Association or Amended and Restated Bye-laws of the Company or the
organizational documents of such affiliate, as the case may be, or any order,
judgment, decree, law, ordinance or regulation applicable to the Company or such
affiliate, as the case may be, or any contract, instrument, agreement or
restriction to which the Company or such affiliate, as the case may be, is a
party or by which the Company or such affiliate, as the case may be, or any of
its assets or properties is bound. Except where the Company is obliged to obtain
Bermuda governmental approvals that have been obtained, neither the Company or
any affiliate thereof nor any of the Company's or any of its affiliates'
respective assets or properties is subject to any charter, bye-law, contract or
other instrument or agreement, order, judgment, decree, law, statute, ordinance
or regulation or any other restriction of any kind or character that would
prevent the Company from entering into this Agreement or from consummating the
transactions contemplated hereby in accordance with the terms hereof.
 
     SECTION 5.5  Regulatory Filings; Compliance with Law.  Upon completion of
the Closing and the use of proceeds therefrom as described in the Offering
Circular, CGA will be authorized on the Closing Date under Bermuda law to
conduct the business of selling insurance and reinsurance as contemplated by the
documents incorporated by reference in the Offering Circular and no further
approvals of insurance regulatory or other authorities are required for the
conduct of such business. Upon completion of the Closing, CGAIM will be
authorized on the Closing Date or immediately thereafter under the applicable
United States federal and state laws to conduct its business as contemplated by
the documents incorporated by reference in the Offering Circular and no further
approvals of regulatory or other authorities are required for the conduct of
such business. Upon completion of the Closing and the use of proceeds therefrom
as described in the Offering
 
                                        6
<PAGE>   11
 
Circular, the Company and the Initial Subsidiaries will be in compliance with
all applicable laws and regulations.
 
     SECTION 5.6  Stamp Duties or Taxes.  No Bermuda stamp, transfer or similar
duties or taxes are payable in respect of the issuance and delivery of the
Shares, and the sale and delivery of the Series C Preferred Stock, to the
Investors pursuant to this Agreement and if any such taxes arise in connection
with the execution of this Agreement, or the consummation of any of the
transactions contemplated hereby, then the Company will pay such taxes.
 
     SECTION 5.7  Private Offering of the Shares.  (a) The offer and sale of the
Series C Preferred Stock and the issuance and delivery of the shares are
intended to be exempt from the provisions of Section 5 of the United States
Securities Act of 1933, as amended (the "Securities Act"), and from the
registration provisions of the applicable state securities laws. Neither the
Company nor anyone acting on its behalf has taken, or omitted to take, any
action, with respect to the Series C Preferred Stock or any securities similar
to the Series C Preferred Stock, or otherwise, that would bring the sale of the
Series C Preferred Stock and the issuance of the shares within the provisions of
Section 5 of the Securities Act or that would violate any blue sky laws of a
state of the United States or securities law of any foreign jurisdiction
(including Bermuda).
 
     (b) In the case of each offer or sale of the Series C Preferred Stock, no
form of general solicitation or general advertising was used by the Company or
any person authorized to act on behalf of the Company, including, without
limitation, any advertisement, article, notice or other communication published
in any newspaper, magazine or similar medium or broadcast over television or
radio, or any seminar or meeting whose attendees have been invited by any
general solicitation or general advertising.
 
     (c) Neither the Company nor anyone acting on its behalf has taken, or
omitted to take, any action, with respect to any other shares of the Company
issued and sold by the Company that would bring the issuance and sale of such
shares within the provisions of Section 5 of the Securities Act or that would
violate any blue sky laws of a state of the United States or securities law of a
foreign jurisdiction (including Bermuda).
 
     (d) Neither the Company nor any Initial Subsidiary has issued or sold, or
agreed to issue or sell, any Series C Preferred Stock of the Company to any
persons other than to the Investors pursuant hereto.
 
     SECTION 5.8  The Offering Circular.  The Offering Circular (including the
documents incorporated therein by reference) does not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. There is no fact which the Company has not
disclosed herein or in the Offering Circular (including the documents
incorporated therein by reference) nor any amendment or supplement thereto as of
the date thereof and at all times subsequent thereto up to the Closing Date
that, so far as the Company can now foresee, is reasonably likely to have a
material adverse effect on the performance of obligations hereunder by the
Company and its Initial Subsidiaries, considered as a whole, or on the business,
operations, financial condition, assets, liabilities or prospects of the Company
and its Initial Subsidiaries taken as a whole.
 
     SECTION 5.9  Not an "Investment Company".  Each of the Company and the
Initial Subsidiaries is not, and when conducting business as contemplated by the
Offering Circular (including the documents incorporated therein by reference)
will not be, an "investment company" or an entity "controlled" by an
\"investment company" as such terms are defined in the United States Investment
Company Act of 1940, as amended.
 
     SECTION 5.10  Company Obligations.  Each of the Company and its Initial
Subsidiaries has incurred no material liens or encumbrances on present or future
assets or revenues and has no material proceedings pending against, or to the
Company's knowledge, threatened against or affecting it before any court,
governmental authority, arbitration board or tribunal, in each of the foregoing
cases, other than as disclosed in the Offering Circular (including the documents
incorporated therein by reference) or referred to herein or in an attachment
hereto.
 
                                        7
<PAGE>   12
 
     SECTION 5.11  Operating Company.  At the time the Company issues any Series
C Preferred Stock, the Company shall be an "operating company" as defined in
United States Department of Labor Regulation section 2510.3-101(c) issued under
the United States Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and the Company shall at all times thereafter conduct its activities
so that it will continue to qualify as such an "operating company." As a result,
pursuant to United States Department of Labor Regulation section
2510.3-101(a)(2)(i), at no time shall the assets of the Company constitute the
assets of any Investor or shareholder of the Company for purposes of Title I of
ERISA or Section 4975 of the United States Internal Revenue Code of 1986 (the
"Code").
 
     SECTION 5.12  No U.S. Trade or Business and Not a Controlled Foreign
Corporation.  The Company shall use its best efforts not to take, and to cause
CGA not to take, any action which the Company has reason to believe could cause
it or CGA to be considered engaged in the conduct of a trade or business in the
United States (within the meaning of Code Section 864) or to become a controlled
foreign corporation (within the meaning of Code Section 957) ("CFC"); provided,
however, that this Section 5.12 shall not apply to any action which affects the
election of directors pursuant to Section 12 of the Amended and Restated
Bye-laws; provided, further, that it is hereby understood that the Company shall
not be considered to violate this Section 5.12 in the event that (x) the board
of directors of the Company (the "Board") shall, in its sole discretion, request
the advice of counsel with respect to a proposed action and counsel determines
that in its opinion it is more likely than not that such proposed action will
not cause the Company or CGA to be engaged in the conduct of a trade or business
in the United States or become a CFC and (y) such proposed action to be taken by
the Company receives the prior approval of at least 75% of the members of the
Board then in office. The foregoing imposes no obligation on the Company or the
Board to seek the advice of counsel prior to taking any action unless the
Company wishes to take advantage of this second proviso to Section 5.12. It is
hereby understood that this Section 5.12 does not alter any provision in the
Company's Amended and Restated Bye-laws and all actions taken in connection
herewith must comply with such Amended and Restated Bye-laws.
 
     SECTION 5.13  Related Person Insurance Income.  (a) The Company shall use
its best efforts to cause CGA not to sell insurance or reinsurance to a U.S.
person that is a shareholder of the Company ("U.S. Shareholder") or a related
person (within the meaning of Section 953(c)(6) of the Code) to a U.S.
Shareholder ("Related Person") and which would therefore generate related person
insurance income (within the meaning of Section 953(c)(2) of the Code) ("RPII")
if the Company knows that (i) 20% or more of CGA's gross insurance income in any
taxable year (interpreted in accordance with Section 953(c)(3)(B) of the Code)
will be RPII and (ii) persons which are directly or indirectly insured or
reinsured by CGA ("Insureds") or Related Persons to Insureds own stock of CGA
that represents 20% or more of the combined voting power of all classes of stock
of the Company that are entitled to vote or 20% or more of the total value of
the Company ("Excess RPII"); provided, however, that it is hereby understood
that the Company shall not be considered to violate this Section 5.13(a) by
virtue of such sale which the Company has reason to believe will generate Excess
RPII if the Company receives the prior approval of 100% of the members of the
Board then in office; provided, further, that it is hereby understood that this
Section 5.13(a) does not alter any provision in the Amended and Restated
Bye-laws and all actions taken in connection herewith must comply with such
Amended and Restated Bye-laws.
 
     (b) In the event that the Board shall have given prior authorization (as
provided in subsection (a) of this Section 5.13) for CGA to sell insurance or
reinsurance which the Company has reason to believe will generate Excess RPII
for any tax year, then, unless a U.S. statute, a final regulation of the U.S.
Treasury or a published ruling of the U.S. Internal Revenue Service issued after
the Closing Date provides or establishes that subpart F insurance income (as
defined in Code Section 953) does not constitute unrelated business taxable
income (as defined in Code Section 512), the Company shall notify any U.S.
Shareholder that the Company knows is subject, pursuant to Code Section 511, to
tax only on its unrelated business taxable income not later than June 30 of the
tax year in which the Company proposes that CGA generate Excess RPII of such
authorization.
 
     SECTION 5.14  Operating Guidelines.  Attached hereto as Annex V is a true,
correct and complete copy of the operating guidelines of the Company and the
Initial Subsidiaries (the "Operating Guidelines"),
                                        8
<PAGE>   13
 
which were adopted by all necessary corporate action of the Board at a duly
called and convened meeting of the Board. The resolutions pursuant to which the
Operating Guidelines were adopted provide that the Operating Guidelines may only
be amended or revoked pursuant to a resolution adopted by a two-thirds vote of
the Board at a duly called and convened meeting of the Board. To the extent the
Operating Guidelines are followed by the Company and the Initial Subsidiaries,
(i) neither the Company nor CGA will be considered to be engaged in the conduct
of a trade or business in the United States through a U.S. "permanent
establishment" as defined in Article 3 of the Convention between the Government
of the United States of America and the Government of the United Kingdom of
Great Britain and Northern Ireland (on behalf of the Government of Bermuda)
relating to the Taxation of Insurance Enterprises and Mutual Assistance in Tax
Matters and (ii) neither the Company nor any Initial Subsidiaries will be
considered to be transacting the business of insurance in any state of the
United States without appropriate licenses or approvals.
 
     SECTION 5.15  Passive Foreign Investment Company.  The Company shall use
its best efforts to operate its business and the business of CGA in such manner
that neither the Company nor CGA will be considered a passive foreign investment
company within the meaning of Section 1297(a) of the Code.
 
     SECTION 5.16  Use of Proceeds of the Offering.  The net proceeds from the
Rights Offering shall be used by the Company for general corporate purposes and,
at the Company's discretion, to make a capital investment in CGA, which will use
such funds, if any, for general corporate purposes.
 
     SECTION 5.17  Shareholders.  Schedule II to this Agreement represents the
Company's best information regarding the identity and ownership interests of the
shareholders of the Company upon completion of the Closing. The Investors
acknowledge and agree that a true and complete list of the shareholders of the
Company and their respective shareholdings shall not be known at the time each
Investor executes this Agreement but shall be calculable upon expiration of the
Rights and after application of the Maximum Percentage limitation and
oversubscription and additional allotment allocations described herein. The
Company agrees to provide at the Closing an Amended and Restated Schedule II
which sets its best information regarding the identity of the shareholders of
the Company and their respective shareholdings on the Closing Date.
 
     SECTION 5.18  Bermuda Withholding Tax.  The making of payments to any
holder of the shares will not be subject to any tax withholding requirement
under current Bermuda tax law.
 
     SECTION 5.19  No Events of Non-Compliance.  No event has occurred and no
condition exists which, upon the consummation of transactions under this
Agreement would constitute an Event of Non-Compliance (as defined in the Series
A Subscription Agreement) with or without notice or lapse of time or both.
 
     SECTION 5.20  Registration Rights.  Other than as provided in the Amended
and Restated Shareholders Agreement, the Company has not agreed to register any
of its Series C Preferred Stock under the Securities Act.
 
                                   ARTICLE 6
 
                REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

and Restated Shareholders Agreement has been duly authorized, executed and
delivered by such Investor at the Closing, and assuming, in the case of the
Amended and Restated Shareholders Agreement, the due authorization, execution
and delivery thereof by the other parties thereto, will constitute a valid and
binding obligation of such Investor enforceable against such Investor in
accordance with its terms, subject to the Creditor and Enforceability
Exceptions.
 
     SECTION 6.3  Investment Intent.  (a) Such Investor is acquiring the Series
C Preferred Stock for its own account as principal or for one or more separate
accounts maintained by such Investor or for the account of one or more pension
or trust funds of which such Investor is trustee, in each case, for investment
purposes only, and not with a view to, or for, the resale or other distribution
thereof, in whole or in part; provided that, subject to the terms hereof, the
disposition of such Investor's or their property shall at all times be within
such Investor's or their control.
 
     (b) If the Series C Preferred Stock is acquired for the account of one or
more pension or trust funds, such Investor is acting as sole trustee (other than
with respect to the Investors listed on Schedule III) and has sole investment
discretion with respect to such Investor's acquisition of the Series C Preferred
Stock, and the determination and decision on such Investor's behalf to acquire
the Series C Preferred Stock for such pension or trust funds is being made by
the same individual or group of individuals who customarily pass on such
investments so that such Investor's decision as to acquisitions for all such
funds is the result of one study and conclusion. Such Investor (i) is an
insurance company and is using the assets of its general account or (ii) has
advised the Company in writing of such Investor's form of organization and,
except with respect to a commingled trust account, the accounts for which such
Investor is purchasing, and all such information provided to the Company is true
and correct as of the date hereof.
 
     SECTION 6.4  No Conflict with Other Instruments; No Approvals Required
Except as Have Been Obtained.  The execution and delivery of this Agreement and
Amended and Restated Shareholders Agreement by such Investor and the compliance
by such Investor with the terms and conditions hereof and thereof will not
violate, with or without the giving of notice or the lapse of time, or both, or
require any registration, qualification, approval or filing under, any provision
of law, statute, ordinance or regulation applicable to such Investor, and will
not conflict with, or require any consent or approval under, or result in the
breach or termination of any provision of, or constitute a default under, or
result in the acceleration of the performance of the obligations of such
Investor under, or result in the creation of any claim, lien, charge or
encumbrance upon any of the properties, assets or businesses of such Investor
pursuant to the articles of incorporation or bye-laws of such Investor (if such
Investor is a corporation) or equivalent organizational documents (if such
Investor is not a corporation) or any order, judgment, decree, law, statute,
ordinance or regulation applicable to such Investor or any contract, instrument,
agreement or restriction to which such Investor is a party or by which such
Investor or any of its assets or properties is bound other than any such (i)
violation, (ii) failure to register, qualify, obtain approval or file, (iii)
conflict, (iv) breach, termination or default, (v) acceleration, or (vi)
creation of claim, lien, charge or encumbrance that would not, individually or
in the aggregate, have a material adverse effect on such Investor's ability to
consummate the transactions contemplated hereby. Neither such Investor nor any
of its assets or properties is subject to any charter, bye-law, contract or
other instrument or agreement, order, judgment, decree, law, statute, ordinance
or regulation or any other restriction of any kind or char acter that would
prevent such Investor from entering into this Agreement or the Amended and
Restated Shareholders Agreement or from consummating the transactions
contemplated hereby or thereby in accordance with the terms hereof or thereof
other than that which would not, individually or in the aggregate have a
material adverse effect on such Investor's ability to consummate the
transactions contemplated in accordance with the terms hereof or thereof.
Notwithstanding anything in this Agreement to the contrary, no representation or
warranty is made by any Investor regarding compliance with ERISA or Section 4975
of the Code, or the effect under ERISA or Section 4975 of the Code of the
execution and delivery of this Agreement and the Amended and Restated
Shareholders Agreement by such Investor and the compliance by such Investor with
the terms and conditions hereof or thereof.

     SECTION 6.5  Investor Awareness and Suitability.  Such Investor
acknowledges, agrees and is aware that:
 
          (i) An investment in the Series C Preferred Stock involves a high
     degree of risk, including, without limitation, the risks identified under
     the caption "Risk Factors" in the Offering Circular, and such Investor may
     lose the entire amount of its investment and such Investor has the
     knowledge and experience in financial affairs that it is capable of
     evaluating the merits and risks of purchasing the Series C Preferred Stock;
 
          (ii) The Company has only recently been organized and has limited
     financial and operating history;
 
          (iii) The Offering Circular contains a summary of certain United
     States and Bermuda tax consequences under current laws relating to (i) the
     United States federal income taxation of the Company and CGA and of U.S.
     Persons (as defined below) and non-U.S. Persons that own Series C Preferred
     Stock of the Company and (ii) the Bermuda taxation of persons or entities
     not resident in Bermuda for exchange control purposes that own Series C
     Preferred Stock of the Company. Positions of, and developments in rulings
     of, the United States Internal Revenue Service, court decisions or
     legislative or administrative actions may have an adverse effect on one or
     more of the tax benefits sought by the Company. Moreover, the Company
     retains the right to alter the conduct of its affairs in such a manner as
     to subject its business to United States federal and/or state taxation,
     subject to the limitations set forth in Section 5.12 and the Operating
     Guidelines. The Offering Circular does not address the Bermuda taxation of
     Investors that are resident in Bermuda for exchange control purposes or the
     taxation of Investors by any jurisdiction other than the United States or
     Bermuda, which tax consequences may be significantly different from the tax
     consequences discussed in the Offering Circular. (For purposes of this
     Section 6.5, "U.S. Person" means (1) an individual who is a citizen or
     resident of the United States, (2) a company, corporation or partnership
     created or organized under the laws of the United States or any state
     thereof, (3) an estate the income of which, from non-United States sources
     and not effectively connected with the conduct of a trade or business in
     the United States, is includable in gross income for United States federal
     income tax purposes, and (4) a trust in respect of which (i) a court within
     the United States may exercise primary supervision over its administration,
     and (ii) one or more United States fiduciaries have the authority to
     control all substantial decisions);
 
          (iv) No Bermuda or United States federal or state regulatory authority
     or any foreign agency has passed upon the accuracy, adequacy, validity or
     completeness of the Offering Circular, this Agreement or the Amended and
     Restated Shareholders Agreement or made any finding or determination as to
     the fairness of an investment in the Series C Preferred Stock;
 
          (v) The Series C Preferred Stock is illiquid, and such Investor must
     bear the financial risk of investment in the Series C Preferred Stock for
     an indefinite period of time and such Investor represents and warrants that
     such Investor has the financial ability to bear the financial risk of its
     investment, and, except for Starwood CGA, LLC, CGA Firemark Venture Fund I,
     LLC and Lennar CGA Holdings, Inc., such Investor's investment does not
     exceed ten percent (10%) of such Investor's net worth;
 
          (vi) The Amended and Restated Bye-laws, the Amended and Restated
     Shareholders Agreement and this Agreement contain substantial restrictions
     on the transferability of the Series C Preferred Stock;
 
          (vii) There is no existing public or other market for the Series C
     Preferred Stock, and it is not expected that any such market will develop.
     There can be no assurance that such Investor will be able to sell or
     dispose of such Investor's Series C Preferred Stock. Without limiting the
     generality of the foregoing, in order not to jeopardize the exempt status
     under the Securities Act or under the securities laws of any other
     jurisdiction of the offering contemplated hereby, the transferee of such
     Series C Preferred Stock may, among other things, be required to fulfill
     the investor suitability requirements thereunder;
 
          (viii) The Series C Preferred Stock has not been registered under the
     Securities Act or under the securities laws of any other jurisdiction,
     including the states of the United States and, except as provided in the
     Amended and Restated Shareholders Agreement, the Company is under no
     obligation to, and
                                       11
<PAGE>   16
 
     currently does not intend to, register or qualify the Series C Preferred
     Stock for resale by such Investor or assist such Investor in complying with
     any exemption under the Securities Act or the securities laws of any such
     jurisdiction or any other jurisdiction. An offer or sale of Series C
     Preferred Stock by such Investor in the absence of registration under such
     securities laws will require the availability of an exemption thereunder. A
     restrictive legend in substantially the form set forth in Section 7.1
     hereof shall be placed on the certificates representing the Series C
     Preferred Stock and a notation shall be made in the appropriate records of
     the Company indicating that the Series C Preferred Stock is subject to
     restrictions on transfer;
 
          (ix) Such Investor shall hold the Series C Preferred Stock subject to
     this Agreement, the Amended and Restated Bye-laws of the Company and the
     Amended and Restated Shareholders Agreement from time to time in effect and
     shall have voting rights with respect to the Series C Preferred Stock as
     specified in the Amended and Restated Bye-laws of the Company from time to
     time in effect and subject to applicable law; and
 
          (x) It is intended that no person or entity may acquire or own,
     directly, indirectly or by attribution (within the meaning of Section 958
     of the Code) 10% or more of the total combined voting power of the Common
     Stock, the Series A Preferred Stock and the Series C Preferred Stock as
     such voting power is described in the Amended and Restated Bye-laws.
 
     SECTION 6.6  Accredited Investor Status.  Such Investor hereby represents
and warrants to the Company that it qualifies as an "accredited investor" within
the meaning of Rule 501(a) of Regulation D under the Securities Act because such
Investor is:
 
          (a) A bank as defined in Section 3(a)(2) of the Securities Act or a

     a state of the United States, its political subdivisions, or an agency or
     instrumentality of such state or its political subdivisions for the benefit
     of its employees, if such plan has total assets in excess of U.S.
     $5,000,000; an employee benefit plan within the meaning of the ERISA, if
     the investment decision is made by a plan fiduciary, as defined in Section
     3(21) of ERISA, which is either a bank, savings and loan association,
     insurance company, or registered investment advisor, or if the employee
     benefit plan has total assets in excess of U.S. $5,000,000 or, if a
     self-directed plan, with investment decisions made solely by persons that
     are accredited investors; or
 
          (b) A private business development company as defined in Section
     202(a)(22) of the United States Investment Advisers Act of 1940; or an
     organization described in Section 501(c)(3) of the Code, corporation,
     Massachusetts or similar business trust, or partnership, not formed for the
     specific purpose of acquiring the Series C Preferred Stock, with total
     assets in excess of U.S. $5,000,000; or
 
          (c) A director, executive officer or general partner of the Company;

     year or (ii) whose individual net worth, or joint net worth with his or her

     total liabilities; or
 
          (e) A trust, with total assets in excess of U.S. $5,000,000, not

                                       12
<PAGE>   17
 
          (f) An entity in which all of the equity owners are accredited
     investors.
 
     SECTION 6.7  Receipt of Information, Access to Information.  Such Investor:
 
          (a) has been furnished with the Offering Circular, the documents
     incorporated by reference therein, the Amended and Restated Bye-laws of the
     Company, the Amended and Restated Shareholders Agreement and any documents
     that may have been made available upon such Investor's request (such
     documents, other than the Offering Circular, being collectively referred to
     as the "Other Documents"), and such Investor has carefully read the
     Offering Circular, the documents incorporated therein by reference and the
     Other Documents and understands and has evaluated the risks of a purchase
     of the Series C Preferred Stock, including the considerations set forth
     under the caption "Investment Considerations" in the Offering Circular;
 
          (b) has been given the opportunity to ask questions of, and receive
     answers from the Company concerning the terms and conditions of the
     offering contemplated hereby and other matters pertaining to an investment
     in the Series C Preferred Stock, has been given the opportunity to obtain
     such additional information necessary to evaluate the merits and risks of a
     purchase of the Series C Preferred Stock to the extent the Company
     possesses such information, and has received all documents and information
     that it has requested relating to an investment in the Series C Preferred
     Stock;
 
          (c) has not relied upon any representations or other information
     (whether oral or written) from the Company or its directors, officers or
     affiliates, or from any other persons, other than the representations
     contained in this Agreement and the information contained or incorporated
     by reference in the Offering Circular and the Other Documents; and
 
          (d) has carefully considered and has, to the extent such Investor
     believes such discussion necessary, discussed with such Investor's
     professional legal, financial and tax advisers, the suitability of an
     investment in the Series C Preferred Stock for such Investor's particular
     financial and tax situation and has determined that such Investor's Series
     C Preferred Stock is a suitable investment for such Investor.
 
     SECTION 6.8  Series C Preferred Stock Ownership Limitations.  To such
Investor's knowledge, such Investor's purchase on the Closing Date of Series C
Preferred Stock pursuant to this Agreement will not cause any person or entity
to own on the Closing Date directly, indirectly or by attribution (within the
meaning of Section 958 of the Code) 10% or more of the total combined voting
power of the Common Stock, the Series A Preferred Stock and the Series C
Preferred Stock as such voting power is described in the Bye-Laws or to be
treated by virtue of its ownership of stock in the Company as indirectly or
constructively owning on the Closing Date 10% or more of the voting power of all
classes of capital stock of CGA entitled to vote. Such Investor may rely on the
list of anticipated shareholders of the Company and their respective anticipated
shareholdings set forth in Schedule II hereto for purposes of making this
representation and warranty.
 
     At such time as the Company supplies the Investors with names of the Series
C Preferred Stock investors, prior to the Closing, the Investors will indicate
whether the inclusion of any of the names will cause any person or entity to own
on the Closing Date directly, indirectly or by attribution (within the meaning
of Section 958 of the Code), 10% or more of the total combined voting power of
the Common Stock, the Series A Preferred Stock and the Series C Preferred Stock
as such voting power is described in the Bye-Laws or to be treated by virtue of
its ownership of stock in the Company as indirectly or constructively owning on
the Closing Date 10% or more of the voting power of all classes of capital stock
of CGA entitled to vote.

by the Company's Amended and Restated Bye-laws or applicable law, each
certificate representing the Series C Preferred Stock and any shares of Common
Stock issuable upon conversion of the Series C Preferred Stock shall (unless
otherwise permitted by the provisions of this Article 7) be stamped or otherwise
imprinted with a legend in substantially the following form:
 
       "Any sale, assignment, transfer, pledge or other disposition of the
       shares represented by this certificate is restricted by, and the rights
       of the holder of such securities are subject to, the terms and conditions
       contained in the Amended and Restated Bye-laws of CGA Group, Ltd. (the
       "Company"), the Series C Cumulative Convertible Preferred Stock
       Subscription Agreement and the Amended and Restated Shareholders
       Agreement which are available for examination by holders of these shares
       at the registered office of the Company. In addition to the foregoing
       restrictions, these securities have not been registered under the United
       States Securities Act of 1933, as amended (the "Securities Act") or under
       the securities laws of any jurisdiction and may not be transferred, sold
       or otherwise disposed of unless a registration statement is in effect
       under the Securities Act and any applicable securities laws with respect
       to such shares or a written opinion of counsel acceptable to the Company
       is provided to the Company to the effect that no registrations are
       required under such securities laws. The prior approval of the Bermuda
       Monetary Authority is not required for any sale, assignment, transfer,
       pledge or other disposition of the securities represented by this
       certificate provided that any such sale, assignment, transfer, pledge or
       other disposition is between persons who are designated as non-residents
       of Bermuda for the purposes of the Exchange Control Act, 1972."
 
     SECTION 7.2  Notice of Proposed Transfers.  (a) The holder of any
securities bearing the entire restrictive legend set forth in Section 7.1 above
("Restricted Securities"), by acceptance thereof, agrees that, unless a
registration statement is in effect under the Securities Act and under
applicable securities laws with respect to such Restricted Securities, prior to
any transfer or attempted transfer of such Restricted Securities, such holder
will give the Company (i) unless the transferee is an Affiliate of the
transferor (as defined in the Amended and Restated Shareholders Agreement),
written notice describing the proposed transfer of any Restricted Securities in
reasonable detail only to the extent necessary to evaluate whether such transfer
is in compliance with the applicable securities laws, the Amended and Restated
Shareholders Agreement and the Amended and Restated Bye-laws sections 61 through
63, (ii) unless the transferee is an Affiliate of the transferor (as defined in
the Amended and Restated Shareholders Agreement), such other information about
the proposed transfer of such Restricted Securities or the proposed transferee
of such Restricted Securities as the Company may reasonably request only to the
extent necessary to evaluate whether such transfer is in compliance with the
applicable securities laws, the Amended and Restated Shareholders Agreement and
61 through 63 of the Amended and Restated Bye-laws, and (iii) an opinion of
counsel (both counsel and opinion reasonably satisfactory to the Company (it
being understood that in-house counsel for such holder shall be considered
satisfactory to the Company)) to the effect that the proposed transfer of such
Restricted Securities may be effected without registration of such Restricted
Securities under the Securities Act and under other applicable securities laws.
The Company hereby acknowledges that no prior approval of the Bermuda Monetary
Authority is necessary for any transfer of restricted shares between persons who
are designated as non-residents of Bermuda for the purposes of the Exchange
Control Act, 1972.
 
     (b) If the holder of the Restricted Securities delivers to the Company an
opinion of counsel that subsequent transfers of such Restricted Securities will
not require registration or qualification under the Securities Act or under
other applicable securities laws, the Company will, or will cause the transfer
agent, if any, for such Restricted Securities promptly after such contemplated
transfer to deliver new certificates for such Restricted Securities that do not
bear that section of the restrictive legend set forth in Section 7.1 above
imposed by the Securities Act and under other applicable securities laws of any
other jurisdictions. If the foregoing conditions entitling the holder to effect
a proposed transfer of such Restricted Securities without registration under the
Securities Act and under other applicable securities laws and the conditions
relating to

the transfer of securities in the Amended and Restated Shareholders Agreement
have not been satisfied, the holder shall not transfer the Restricted
Securities, and the Company will cause the transfer agent not to transfer such
Restricted Securities on its books or issue any certificates representing such
Restricted Securities. Any purported transfer of Restricted Securities not in
accordance with applicable securities laws shall be void.
 
     (c) No Investor shall transfer any shares of Series C Preferred Stock or
any shares of Common Stock issuable upon conversion of the Series C Preferred
Stock held by such Investor unless the transferee of such shares has agreed to
be bound by the terms of the Amended and Restated Shareholders Agreement and has
duly executed a counterpart signature page to the Amended and Restated
Shareholders Agreement. Any transfer or purported transfer made in violation of
this Section 7.2(c) hereof shall be null and void and of no effect and the
Company shall cause any correction required to be made to the register of the
Members of the Company to be effected.
 
     (d) As used in this Agreement, the term "transfer" encompasses any sale,
transfer, pledge or other disposition of any securities referred to herein.

     SECTION 8.11  Full Payment.  (a) All payments in respect of the Series C
Preferred Stock (including, without limitation, redemption and liquidation
payments, and payments under Section 8.11(b)), shall be made in immediately
available U.S. dollar funds, provided, however, that the Company may make
payments or redemptions in shares of Common Stock as set forth in the Bye-laws
attached as Annex II hereto. Each reference in this Agreement to U.S. dollars
(the "relevant currency") is of the essence. To the fullest extent permitted by
law, the obligations of the Company and each Investor in respect of any amount
due under this Agreement will, notwithstanding any payment in any other currency
(whether pursuant to a judgment or otherwise), be discharged only to the extent
of the amount in the relevant currency that the party entitled to receive such
payment may, in accordance with its normal procedures, purchase with the sum
paid in such other currency (after any premium and costs of exchange) on the
business day immediately following the day on which such party receives such
payment. If the amount in the relevant currency that may be so purchased for any
reason falls short of the amount originally due, the Company or such Investor,
as the case may be, will pay such additional amounts, in the relevant currency,
as may be necessary to compensate for the shortfall. Any obligation of the
Company or such Investor, as the case may be, not discharged by such payment
will, to the fullest extent permitted by applicable law, be due as a separate
and independent obligation and, until discharged as provided herein, will
continue in full force and effect.
 
     (b) The Company will make all redemption and liquidation payments to the
holders of Series C Preferred Stock in respect of this Agreement and the Amended
and Restated Bye-laws free and clear of and without deductions or withholding
for or on account of any present or future taxes, duties, assessments, fees or
other governmental charges imposed or levied by or on behalf of Bermuda or any
other jurisdiction from or through which such payment is made to the holders of
Series C Preferred Stock (all such taxes, duties, assessments, fees or other
governmental charges being referred to herein as "Taxes"), unless such
withholding or deduction is required by law. In that event, the Company will pay
to the holders of Series C Preferred Stock such additional amounts as may be
necessary in order that every liquidation and redemption payment made by the
Company after deduction or withholding for or on account of any such present or
future Taxes will not be less than the amount then due and payable in respect of
this Agreement and the Amended and Restated Bye-laws.
 
     SECTION 8.12  Indemnification.  (a) The Company shall defend, hold harmless
and indemnify each Investor and its Affiliates from and against all damages,
losses, costs and expenses (including reasonable legal expenses) to which any of
such persons becomes subject as a result of any inaccuracy in any representation
or
 
                                       16
<PAGE>   21
 
warranty of the Company contained in this Agreement or any document delivered in
connection herewith (including the certificate referred to in Section 3.3) or
the breach of any covenant or agreement of the Company contained in this
Agreement, the Company's Amended and Restated Bye-laws, or the Amended and
Restated Shareholders Agreement.
 
     (b) In the event a party entitled to indemnification under this Agreement
(an "Indemnified Party") becomes aware of a claim, liability, expense or other
event with respect to which such party is entitled to indemnification (an
"Indemnification Event"), such Indemnified Party shall promptly give notice of
such Indemnification Event to the Company. The failure by any Indemnified Party
to give such notice to the Company within a reasonable period of time shall
relieve the Company of its obligations under this Section 8.12, if and to the
extent that it did not otherwise learn of such Indemnification Event and such
failure results in the forfeiture by the Company of substantial rights and
defenses.
 
     (c) The Company shall have the right to defend, contest, settle or
otherwise resolve any Indemnification Event involving a third-party claim (a
"Third-Party Indemnification Event") as long as the Indemnification Event may
not possibly give rise to a non-monetary liability, including, without
limitation, injunctions and criminal liability; provided, however, that the
Company shall not settle or compromise any Third-Party Indemnification Event
without the Indemnified Party's prior written consent thereto, unless the terms
of such settlement or compromise provide for an unconditional release of the
Indemnified Parties. Notwithstanding the foregoing, any Indemnified Party shall
have the right to employ separate counsel (including local counsel), and the
Company shall bear the reasonable costs, fees and expenses of such separate
counsel if (i) the use of counsel chosen by the Company to represent such
Indemnified Party would present such counsel with any actual or potential
conflict of interest, (ii) the actual or potential defendants in, or targets of,
any Third-Party Indemnification Event include both such Indemnified Party and
the Company or any Affiliate thereof and such Indemnified Party shall have
reasonably concluded that there may be legal defenses available to it which are
different from or additional to those available to the Company or any Affiliate
thereof which is an actual or potential defendant in, or target of, such
Third-Party Indemnification Event, (iii) the Indemnification Event may give rise
to a non-monetary liability including, without limitation, injunctions and
criminal liability, or (iv) the Company has authorized such Indemnified Party to
employ separate counsel. The Indemnified Parties and the Company shall cooperate
fully in defending any Third-Party Indemnification Event, and the Company shall
have reasonable access to the books and records and personnel of the Indemnified
Parties that are relevant hereto.
 
     (d) The indemnification provisions of this Article 8 shall be in addition
to any rights each Indemnified Party may otherwise have.
 
     SECTION 8.13  Submission to Jurisdiction.  The Company irrevocably submits
to the non-exclusive jurisdiction of any New York State or federal court sitting
in The City of New York and any court sitting in Bermuda, and any appellate
court from any thereof, in any suit, action or proceeding arising out of or
relating to this Agreement or the transactions contemplated hereby (a "Related
Proceeding"), and the Company hereby irrevocably agrees that all claims in
respect of any Related Proceeding may be heard and determined in such New York
State or federal court or any court sitting in Bermuda. The Company hereby
irrevocably waives, to the fullest extent it may effectively do so, the defense
of an inconvenient forum to the maintenance of any Related Proceeding and any
objection to any Related Proceeding on the grounds of venue, residence or
domicile. A final judgment in any such suit, action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
any other manner provided by law.
 
     The Company hereby irrevocably appoints the CT Corporation System (the
"Process Agent"), with an office on the date hereof at 1633 Broadway, New York,
New York, United States of America, as its agent to receive on behalf of the
Company and its property service of copies of the summons and complaint and any
other process that may be served in any Related Proceeding in such New York
State or federal court sitting in The City of New York. Service may be made by
U.S. registered mail or other comparable means or by delivering by hand a copy
of such process to the Company in care of the Process Agent at the address
specified above for the Process Agent (such service to be effective upon the
mailing or delivery by hand of such process to the office of the Process Agent),
and the Company hereby irrevocably authorizes and directs the Process
 
                                       17
<PAGE>   22
 
Agent to accept on its behalf such service. Failure of the Process Agent to give
notice to the Company, or failure of the Company to receive notice of such
service of process, shall not affect in any way the validity of such service on
the Process Agent or the Company. As an alternative method of service, the
Company also irrevocably consents to the service of any and all process in any
Related Proceeding in a New York State or federal court sitting in The City of
New York by sending by U.S. registered mail or other comparable means copies of
such process to the Company at its address under Section 8.10 (such service to
be effective seven days after mailing thereof). The Company covenants and agrees
that it shall take any and all reasonable action, including the execution and
filing of any and all documents, that may be necessary to continue the
designation of the Process Agent in full force and effect, and to cause the
Process Agent to continue to act as such. Nothing herein shall affect the right
of any party to serve legal process in any other manner permitted by law or
affect the right of any party to bring any suit, action or proceeding against
any other party or its property in the courts of other jurisdictions.
 
     To the extent that the Company has or hereafter may acquire any immunity
from any legal action, suit or proceeding, from jurisdiction of any court or
from setoff or any legal process (whether through service or notice, attachment
in aid of execution or otherwise) with respect to itself or any of its property,
the Company hereby irrevocably waives and agrees not to plead or claim such
immunity in respect of its obligations under this Agreement.
 
     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

                                 INTERPRETATION
 
1.  INTERPRETATION
 
     (1) In these Bye-laws the following words and expressions shall, where not
inconsistent with the context, have the following meanings respectively:
 
            (a) "Act" means the Companies Act 1981 as amended from time to time;
 
            (b) "Affiliate" of any specified Person means any other Person
     directly or indirectly controlling or controlled by or under direct or
     indirect common control with such specified Person and includes each
     officer, director, trustee or general partner of such Person, and each
     owner of 10% or more of any class of voting stock or interests of such
     Person. For the purposes of this definition, "control" when used with
     respect to any specified Person means the power to direct the management
     and policies of such Person, directly or indirectly, whether through the
     ownership of voting securities, by contract or otherwise; and the terms
     "controlling" and "controlled" have meanings correlative to the foregoing.
     A Person shall not be deemed an Affiliate of the Company solely through
     possession of the right to elect one director;
 
            (c) "Affiliated Member" means with respect to any other Member a

    (T X Maximum Percentage) - 1
    ----------------------------
                 C
 
     Where:
 
            "T" is the aggregate number of votes conferred by all of the issued
            and outstanding shares of the Company, and
 
            "C" is the number of votes conferred by the Controlled Shares of
            such Person.
 
     (3) If, as a result of giving effect to the foregoing provisions of this
Bye-law 50 or otherwise, the votes conferred by the Controlled Shares of a
Person would otherwise represent an amount equal to or greater than the Maximum
Percentage applicable to such Person, the votes conferred by the Controlled
Shares of such Person shall be reduced in accordance with the foregoing
provisions of this Bye-law 50. Such process shall be repeated until the votes
conferred by the Controlled Shares of each Person represent less than the
Maximum Percentage applicable to such Person. The limitations described in this
subparagraph shall not apply to the designation of Directors by certain Members
or classes of Members pursuant to subparagraphs (2) and (3) of Bye-law 12,
subparagraph (1) of Bye-law 15 and subparagraph (1) of Bye-law 16.
 
     (4) Notwithstanding any other provisions of these Bye-laws to the contrary,
with respect to any matter required to be submitted to a vote of the members of
the Insurance Subsidiary, the Company shall be required to submit a proposal
relating to such matters to the Members who shall vote at a meeting in
accordance with these Bye-laws and shall vote all the shares of the Insurance
Subsidiary held by the Company in accordance with and proportional to such vote
of the Members; PROVIDED THAT the Board shall not be required to submit such a
proposal contemplated by this Bye-law 50(4) to the Members at such time as the
Insurance Subsidiary shall no longer be a subsidiary of the Company.
 
  51.  POWER TO ISSUE SHARES
 
     (1) Subject to these Bye-laws and to any resolution of the Members to the
contrary and without prejudice to any special rights previously conferred on the
holders of any existing shares or class of shares, including, without
limitation, the rights of preemption contained in the Shareholders Agreement,
the Board shall have power to issue any unissued and authorised shares of the
Company on such terms and conditions as it may determine and any such shares or
class of shares may be issued with such preferred, deferred or other
                                       16
<PAGE>   21
 
special rights or such restrictions, whether in regard to dividend, voting,
return of capital or otherwise as the Company may from time to time by
resolution of the Members prescribe; PROVIDED THAT the Board shall have used its
best efforts to assure that upon consummation of any such issuance or
determination no Person shall hold the Maximum Percentage applicable to such
Person in terms of voting power of the Controlled Shares.
 
     (2) The Board shall, in connection with the issue of any share, have the
power to pay such commission and brokerage as may be permitted by law.
 
     (3) The Company shall not give, whether directly or indirectly, whether by
means of loan, guarantee, provision of security or otherwise, any financial
assistance for the purpose of a purchase or subscription made or to be made by
any Person of or for any shares in the Company, but nothing in this Bye-Law
shall prohibit transactions mentioned in Sections 39A and 39B of the Act.
 
     (4) Subject to the rights of the holders of any existing classes of shares,
the Company may from time to time do any one or more of the following things:
 
          (a) make arrangements on the issue of shares for a difference between
     the Members in the amounts and times of payments of calls on their shares;
 
          (b) accept from any Member the whole or a part of the amount remaining
     unpaid on any shares held by him, although no part of that amount has been
     called up;
 
          (c) pay dividends in proportion to the amount paid up on each share
     where a larger amount is paid up on some shares than on others; and
 
          (d) issue its shares in fractional denominations and deal with such
     fractions to the same extent as its whole shares and shares in fractional
     denominations shall have in proportion to the respective fractions
     represented thereby all of the rights of whole shares including (but
     without limiting the generality of the foregoing) the right to vote, to
     receive dividends and distributions and to participate in a winding up.
 
52.  VARIATION OF RIGHTS, ALTERATION OF SHARE CAPITAL AND PURCHASE OF SHARES OF
THE COMPANY
 
     (1) Subject to the provisions of Sections 42 and 43 of the Act and the
terms of the Preference Shares, any preference shares may be issued or converted
into shares that, at a determinable date or at the option of the Company, are
liable to be redeemed on such terms and in such manner as the Company before the
issue or conversion may by resolution of the Members determine.
 
     (2) If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may, whether or not the Company is being
wound up, be varied, subject to the terms of such shares and, in the case of the
Preference Shares, the Appendices hereto, with the consent in writing of the
holders of three-fourths of the issued shares of that class or with the sanction
of a resolution passed by a majority of the votes cast at a separate general
meeting of the holders of the shares of the class in accordance with Section
47(7) of the Act. The rights conferred upon the holders of the shares of any
class issued with preferred or other rights shall not, unless otherwise
expressly provided by the terms of issue of the shares of that class, be deemed
to be varied by the creation or issue of further shares ranking pari passu
therewith.
 
     (3) The Company may from time to time by resolution of the Members change
the currency denomination of, increase, alter or reduce its share capital in
accordance with the provisions of Sections 45 and 46 of the Act, subject to the
terms of such shares and, in the case of the Preference Shares, the Appendices
hereto. Where, on any alteration of share capital, fractions of shares or some
other difficulty would arise, the Board may deal with or resolve the same in
such manner as it thinks fit including, without limiting the generality of the
foregoing, the issue to Members, as appropriate, of fractions of shares and/or
arranging for the sale or transfer of the fractions of shares of Members.
 
     (4) The Company may from time to time redeem or purchase its own shares in
accordance with Bye-law 11 or otherwise and the provisions of Sections 42 and
42A of the Act; PROVIDED THAT, except in
 
                                       17
<PAGE>   22
 
the case of a redemption or purchase of Series A Preference Shares during an
Event of Non-Compliance, the Company shall have used its best efforts to ensure
that upon consummation of any such redemption or purchase no Person shall hold
the Maximum Percentage applicable to such Person in terms of voting power of the
Controlled Shares.
 
53.  REGISTERED HOLDER OF SHARES
 
     (1) The Company shall be entitled to treat the registered holder of any
share as the absolute owner thereof and accordingly shall not be bound to
recognize any equitable or other claim to, or interest in, such share on the
part of any other Person.
 
     (2) Any dividend, interest or other moneys payable in cash in respect of
shares may be paid by cheque or draft sent through the post directed to the
Member at such Member's address in the Register of Members or, in the case of
joint holders, to such address of the holder first named in the Register of
Members, or to such Person and to such address as the holder or joint holders
may in writing direct. If two or more Persons are registered as joint holders of
any shares any one can give an effectual receipt for any dividend paid in
respect of such shares.
 
54.  DEATH OF A JOINT HOLDER
 
     Where two or more Persons are registered as joint holders of a share or
shares then in the event of the death of any joint holder or holders the
remaining joint holder or holders shall be absolutely entitled to the said share
or shares and the Company shall recognize no claim in respect of the estate of
any joint holder except in the case of the last survivor of such joint holders.
 
55.  SHARE CERTIFICATES
 
     (1) Every Member shall be entitled to a certificate under the seal of the
Company (or a facsimile thereof) specifying the number and, where appropriate,
the class of shares held by such Member and whether the same are fully paid up
and, if not, how much has been paid thereon. The Board may by resolution
determine, either generally or in a particular case, that any or all signatures
on certificates may be printed thereon or affixed by mechanical means.
 
     (2) The Company shall be under no obligation to complete and deliver a
share certificate unless specifically called upon to do so by the Person to whom
such shares have been allotted.
 
     (3) If any such certificate issued to a Member shall be proved to the
satisfaction of the Board to have been worn out, lost, mislaid or destroyed the
Board may cause a new certificate to be issued and request an indemnity from
such Member for the lost certificate if it sees fit.
 
56.  CALLS ON SHARES
 
     (1) The Board may from time to time make such calls as it thinks fit upon
the Members in respect of any monies unpaid on the shares allotted to or held by
such Members and, if a call is not paid on or before the day appointed for
payment thereof, the Member may at the discretion of the Board be liable to pay
the Company interest on the amount of such call at such rate as the Board may
determine, from the date when such call was payable up to the actual date of
payment. The joint holders of a share shall be jointly and severally liable to
pay all calls in respect thereof.
 
     (2) The Board may, on the issue of shares, differentiate between the
holders as to the amount of calls to be paid and the times of payment of such
calls.
 
57.  FORFEITURE OF SHARES
 
     (1) If any Member fails to pay, on the day appointed for payment thereof,
any call in respect of any share allotted to or held by such Member, the Board
may, at any time thereafter during such time as the call
 
                                       18
<PAGE>   23
 
remains unpaid, direct the Secretary to forward to such Member a notice in the
form, or as near thereto as circumstances admit, of Form "B" in the Schedule
hereto.
 
     (2) If the requirements of such notice are not complied with, any such
share may at any time thereafter before the payment of such call and the
interest due in respect thereof be forfeited by a resolution of the Board to
that effect, and such share shall thereupon become the property of the Company
and may be disposed of as the Board shall determine.
 
     (3) A Member whose share or shares have been forfeited as aforesaid shall,
notwithstanding such forfeiture, be liable to pay to the Company all calls owing
on such share or shares at the time of the forfeiture and all interest due
thereon.
 
                              REGISTER OF MEMBERS
 
58.  CONTENTS OF REGISTER OF MEMBERS
 
     The Board shall cause to be kept in one or more books a Register of Members
and shall enter therein the particulars required by the Act.
 
59.  INSPECTION OF REGISTER OF MEMBERS
 
     The Register of Members shall be open to inspection at the registered
office of the Company on every Business Day, subject to such reasonable
restrictions as the Board may impose, so that not less than two hours in each
Business Day be allowed for inspection. The Register of Members may, after
notice has been given by advertisement in an appointed newspaper to that effect,
be closed for any time or times not exceeding in the whole thirty days in each
year.
 
60.  DETERMINATION OF RECORD DATES
 
     Notwithstanding any other provision of these Bye-laws the Board may fix any
date (except that if such date is with respect to the payment of dividends as
provided in any of the Appendices, such date shall always be on the first day of
the month during which such payment is scheduled to be made) as the record date
for:
 
          (a) determining the Members entitled to receive any dividend; and
 
          (b) determining the Members entitled to receive notice of and to vote
     at any general meeting of the Company.
 
                               TRANSFER OF SHARES
 
61.  INSTRUMENT OF TRANSFER
 
     (1) An instrument of transfer shall be in the form or as near thereto as
circumstances admit of Form "C" in the Schedule hereto or in such other common
form as the Board may accept. Such instrument of transfer shall be signed by or
on behalf of the transferor and transferee provided that, in the case of a fully
paid share, the Board may accept the instrument signed by or on behalf of the
transferor alone. The transferor shall be deemed to remain the holder of such
share until the same has been transferred to the transferee in the Register of
Members.
 
     (2) The Board may refuse to recognize any instrument of transfer unless it
is accompanied by the certificate in respect of the shares to which it relates
and by such other evidence as the Board may reasonably require to show the right
of the transferor to make the transfer.
 
62.  RESTRICTION ON TRANSFER
 
     (1) The Board shall refuse to register a transfer unless (x) all applicable
consents, authorisations and permissions of any governmental body or agency in
Bermuda have been obtained and (y) the Board or its
                                       19
<PAGE>   24
 
transfer agent determines that such transfer would not cause the transferee or
any U.S. Person to become a "United States Shareholder" of the Company or the
Insurance Subsidiary, as such term is defined under Section 951(b) of the Code,
as amended; PROVIDED FURTHER, that a request to transfer shall not be
unreasonably refused. A refusal shall not be deemed unreasonable based upon the
failure of the Board to receive evidence of satisfaction of condition (x) or (y)
above. The Board may reasonably require the transferor to show that such
transferor has complied with the terms regarding transfers in the Shareholders'
Agreement to make the transfer, to the extent such terms are applicable to such
transfer. If a transferor is not negligent in providing information to the Board
or its agent in response to a request for such information in connection with a
transfer, the Company shall indemnify and hold harmless such transferor in
respect of any and all liabilities to the Company, its affiliates, holders of
Capital Stock of the Company and their respective affiliates in connection with
such transfer causing the transferee or any U.S. Person to become a United
States Shareholder.
 
     (2) If the Board refuses to register a transfer of any share the Secretary
shall, as soon as practicable but in no event later than five days after the
date on which the transfer request was lodged with the Company or its agent,
send to the transferor and transferee notice of the refusal or acceptance.
 
     (3) Unless a transferor or transferee knowingly provides incorrect
information to the Board or its agent in connection with a proposed transfer,
such transferor or transferee shall have no liability to the Company, its
affiliates, other holders of Capital Stock of the Company and their respective
affiliates in connection with such transfer.
 
63.  TRANSFERS BY JOINT HOLDERS
 
     The joint holders of any share or shares may transfer such share or shares
to one or more of such joint holders, and the surviving holder or holders of any
share or shares previously held by them jointly with a deceased Member may
transfer any such share to the executors or administrators of such deceased
Member.
 
                             TRANSMISSION OF SHARES
 
64.  REPRESENTATIVE OF DECEASED MEMBER
 
     In the case of the death of a Member, the survivor or survivors where the
deceased Member was a joint holder, and the legal personal representatives of
the deceased Member where the deceased Member was a sole holder, shall be the
only persons recognized by the Company as having any title to the deceased
Member's interest in the shares. Nothing herein contained shall release the
estate of a deceased joint holder from any liability in respect of any share
which had been jointly held by such deceased Member with other persons. Subject
to the provisions of Section 52 of the Act, for the purpose of this Bye-law,
legal personal representative means the executor or administrator of a deceased
Member or such other person as the Board may in its absolute discretion decide
as being properly authorised to deal with the shares of a deceased Member.
 
65.  REGISTRATION ON DEATH OR BANKRUPTCY
 
     Any Person becoming entitled to a share in consequence of the death or
bankruptcy of any Member may be registered as a Member upon such evidence as the
Board may deem sufficient or may elect to nominate some Person to be registered
as a transferee of such share, and in such case the Person becoming entitled
shall execute in favour of such nominee an instrument of transfer in the form,
or as near thereto as circumstances admit, of Form "D" in the Schedule hereto.
On the presentation thereof to the Board, accompanied by such evidence as the
Board may require to prove the title of the transferor, the transferee shall be
registered as a Member but the Board shall, in either case, have the same right
to decline or suspend registration as it would have had in the case of a
transfer of the share by that Member before such Member's death or bankruptcy,
as the case may be.

66.  DECLARATION OF DIVIDENDS BY THE BOARD
 
     The Board may, subject to these Bye-laws, including, without limitation,
the terms of the Preference Shares, and in accordance with Section 54 of the Act
and any restrictions contained in Bye-law 51, declare a dividend to be paid to
the Members, in proportion to the number of shares held by them, and such
dividend may be paid in cash or wholly or partly in specie in which case the
Board may fix the value for distribution in specie of any assets.
 
67.  OTHER DISTRIBUTIONS
 
     The Board may declare and make such other distributions (in cash or in
specie) to the Members as may be lawfully made out of the assets of the Company.
 
68.  RESERVE FUND
 
     The Board may from time to time before declaring a dividend set aside, out
of the surplus or profits of the Company, such sum as it thinks proper as a
reserve fund to be used to meet contingencies or for equalizing dividends or for
any other special purpose.
 
69.  DEDUCTION OF AMOUNTS DUE TO THE COMPANY
 
     The Board may deduct from the dividends or distributions payable to any
Member all monies due, if uncontested, from such Member to the Company on
account of calls.
 
                                 CAPITALIZATION
 
70.  ISSUE OF BONUS SHARES
 
     (1) The Board may resolve to capitalise any part of the amount for the time
being standing to the credit of any of the Company's share premium or other
reserve accounts or to the credit of the profit and loss account or otherwise
available for distribution by applying such sum in paying up unissued shares to
be allotted as fully paid bonus shares pro rata to the Members.
 
     (2) The Company may capitalise any sum standing to the credit of a reserve
account or sums otherwise available for dividend or distribution by applying
such amounts in paying up in full partly paid shares of those Members who would
have been entitled to such sums if they were distributed by way of dividend or
distribution.
 
                       ACCOUNTS AND FINANCIAL STATEMENTS
 
71.  RECORDS OF ACCOUNT
 
     The Board shall cause to be kept proper records of account with respect to
all transactions of the Company in accordance with the requirements of the Act
and Section 4 of the Shareholders Agreement, and, in particular, without
limitation, with respect to:
 
          (a) all sums of money received and expended by the Company and the
     matters in respect of which the receipt and expenditure relates;
 
          (b) all sales and purchases of goods by the Company; and
 
          (c) the assets and liabilities of the Company.
 
                                       21

     Such records of account shall be kept at the registered office of the
Company or, subject to Section 83 (2) of the Act, at such other place as the
Board thinks fit and shall be available for inspection by the Directors during
normal business hours.

Members in general meeting.
 
                                     AUDIT
 
74.  APPOINTMENT OF AUDITOR
 
     Subject to Section 88 of the Act, at the annual general meeting or at a
subsequent special general meeting in each year, an independent representative

the Company shall, during his or her continuance in office, be eligible to act
as an Auditor of the Company.

     If the office of Auditor becomes vacant by the resignation or death of the
Auditor, or by the Auditor becoming incapable of acting by reason of illness or
other disability at a time when the Auditor's services are required, the Board
shall, as soon as practicable, convene a special general meeting to fill the
vacancy thereby created.

79.  NOTICES TO MEMBERS OF THE COMPANY
 
     A notice may be given by the Company to any Member either by delivering it
to such Member in person or by sending it to such Member's address in the
Register of Members or to such other address given for the purpose. For the

Persons is named first in the Register of Members and notice so given shall be
sufficient notice to all the holders of such shares.
 
81.  SERVICE AND DELIVERY OF NOTICE
 
     Any notice shall be deemed to have been served at the time when the same
would be delivered in the ordinary course of transmission and, in proving such
service, it shall be sufficient to prove that the notice was properly addressed
and prepaid, if posted, and the time when it was posted, delivered to the
courier or to the cable company or transmitted by telex, facsimile or other
method, as the case may be.
 
                              SEAL OF THE COMPANY

Director, Officer or Resident Representative, may affix the seal of the Company
attested by such Director, Officer or Resident Representative's signature to any
authenticated copies of these Bye-laws, the incorporating documents of the
Company, the minutes of any meetings or any other documents required to be
authenticated by such Director, Officer or Resident Representative.

84.  WINDING-UP/DISTRIBUTION BY LIQUIDATOR
 
     If the Company shall be wound up the liquidator may, with the sanction of a
resolution of the Members and subject to the rights of the holders of the
Preference Shares, divide amongst the Members in specie or in kind the whole or
any part of the assets of the Company (whether they shall consist of property of
the same kind or not) and may, for such purpose, set such value as he or she
deems fair upon any property to be divided as aforesaid and may determine how
such division shall be carried out as between the Members or different classes
of Members. The liquidator may, with the like sanction, vest the whole or any
part of such assets in trustees upon such trusts for the benefit of the Members
as the liquidator shall think fit, but so that no Member shall be compelled to
accept any shares or other securities or assets whereon there is any liability.

                                   APPENDIX A
                                TO THE BYE-LAWS
 
                      DESIGNATIONS, NUMBER, VOTING POWERS,
                             PREFERENCES AND RIGHTS
                                       OF
                  SERIES A CUMULATIVE VOTING PREFERENCE SHARES
 
     1.  Designation and Number.  The Series A Preference Shares shall be for
the purposes of the Act designated as a separate Series of Preference Shares in
the Company and shall be designated the Series A Cumulative Voting Preference
Shares, par value U.S.$.01 per share (the "Series A Preference Shares"); and the
number of shares designated as the Series A Preference Shares shall be initially
10,000,000; provided, that no such shares may be issued in excess of 2,600,000
shares other than as dividends on the Series A Preference Shares or in exchange
for outstanding Series A Preference Shares.
 
     2.  Dividends.
 
     (a) (i) Subject to the provisions of Section 2(b) of this Appendix A, the
holders of Series A Preference Shares shall be entitled to receive, when and as
declared, out of the net profits or surplus of the Company legally available
therefor, dividends per share at the rate of 13.75% per annum (subject to
adjustments as subsequently provided, the "Series A Preferred Dividend Rate")
based on the Series A Preferred Stated Value (as defined below), payable as the
Board may determine; provided that, (A) such dividends accruing on or prior to
June 17, 2002 shall be payable only in Series A Preference Shares (with each
share being valued for this purpose at the Series A Preferred Stated Value) and
(B) such dividends accruing thereafter shall be payable only in cash at a rate
of 11.75% per annum, and, to the extent such dividends accrue in excess of a
rate of 11.75% per annum (the "Excess Dividend Rate"), such Excess Dividend Rate
shall be payable in cash or in Series A Preference Shares (with each share being
valued for this purpose at the Series A Preferred Stated Value), or cash in part
and Series A Preference Shares (with each share being valued for this purpose at
the Series A Preferred Stated Value) in part (such option shall be in the
Company's sole discretion, except that the Company shall use its best efforts to
obtain written assurance from Duff & Phelps Credit Rating Company that the
payment in cash of such Excess Dividend Rate will not adversely affect the AAA
claims paying ability rating of the Insurance Subsidiary and if such assurance
is obtained with respect to all or a portion of such Excess Dividend Rate, then
the entire Excess Dividend Rate or, if such assurance is only with respect to a
portion of the Excess Dividend Rate, such portion, if any, shall be payable only
in cash). The Board shall determine to pay, and shall set apart for or pay, such
dividends to the holders of the Series A Preference Shares before any dividends
(other than the dividends payable in Shares Junior to the Series A Preferred (as
defined below)) shall be set apart for or paid upon the Series B Preference
Shares, the Series C Preference Shares, the Common Shares or any other shares of
Capital Stock ranking on liquidation junior to the Series A Preference Shares
(such shares being referred to hereinafter collectively as "Shares Junior to the
Series A Preferred"). All dividends declared upon Series A Preference Shares
shall be declared pro rata per share.
 
     (ii) Notwithstanding the foregoing, the Series A Preferred Dividend Rate
shall be adjusted as follows (such adjustments being cumulative):
 
          (A) if at any time after June 17, 2002, the Series A Preference Shares
     are rated investment grade (a rating of BBB- or higher from Duff & Phelps
     Credit Rating Company (or any successor thereto) ("DCR") or the
     then-equivalent rating in the event that DCR changes its rating
     designations after June 17, 1997), the Series A Preferred Dividend Rate
     shall be decreased by 200 basis points for the period from such time until
     redemption;
 
          (B) In the event that the Company fails to keep the Registration
     Statement on Form S-1 with respect to the Series A Preference Shares ("the
     Shelf Registration Statement") effective continuously until June 17, 1999
     or such shorter period that will terminate when all the Series A Preference
     Shares required by the Series A Preferred Stock Subscription Agreement to
     be covered by such Shelf
<PAGE>   2
 
     Registration Statement have been sold pursuant to such registration
     statement, then the Series A Preferred Dividend Rate shall be increased or,
     to the extent previously increased as provided below in clause (C) of this
     Section 2(a)(ii), further increased, as the case may be, by 50 basis points
     for the period from the date that the Shelf Registration Statement is no
     longer effective until the earlier of (y) the date the Shelf Registration
     Statement is again deemed effective and (z) June 17, 1999; and
 
          (C) if an Event of Non-Compliance occurs, the Series A Preferred
     Dividend Rate shall be increased or further increased, as the case may be,
     by 250 basis points for the period from the date of such event until the
     date that no Event of Non-Compliance is continuing.
 
     (b) Dividends on the Series A Preference Shares shall be fully cumulative,
whether or not in any fiscal year there shall be net profits or surplus
available for the payment of dividends in such fiscal year, so that, if in any
fiscal year or years, dividends in whole or in part are not paid upon the Series
A Preference Shares, unpaid dividends shall accrue quarterly at the Series A
Preferred Dividend Rate and be compounded quarterly. Dividends on the Series A
Preference Shares shall accrue at the Series A Preferred Dividend Rate based on
the actual number of days elapsed over a year of 360 days from June 17, 1997
through and until the redemption of such shares.
 
     3.  Liquidation, Dissolution or Winding Up.
 
     (a) In the event of any voluntary or involuntary liquidation, dissolution
or winding up of the Company or similar procedures affecting the Company, and
after the Company has paid or set aside all amounts due to creditors and any
dividends accrued but unpaid on the Series A Preference Shares pursuant to
Sections 2(a) and (b) above (and any dividends accrued but unpaid with respect
to any such accrued but unpaid dividends as a result of compounding at a
quarterly rate) through the date of such liquidation, dissolution or winding up
or similar procedure, the holders of Series A Preference Shares then issued and
outstanding shall be entitled, on a pro rata per share basis, to be paid out of
the assets of the Company available for distribution to its Members, before any
payment shall be made to the holders of Shares Junior to the Series A Preferred,
an amount equal to US $25.00 (the "Series A Preferred Stated Value") per share,
subject to adjustment in the event of any share split or combination with
respect to such shares. The aggregate of all liquidation payments to which the
holder of a Series A Preference Share shall become entitled under this Section 3
with respect to each Series A Preference Share held by it shall be referred to
as its "Series A Liquidation Value."
 
     (b) If upon any such liquidation, dissolution or winding up of the Company
(or similar procedure affecting the Company) the remaining assets of the Company
available for the distribution to its shareholders shall be insufficient to pay
the holders of Series A Preference Shares the full Series A Liquidation Value
for each Series A Preference Share held by such holders, the holders of Series A
Preference Shares and the holders of any class of shares ranking on liquidation
on parity with the Series A Preference Shares, if any, shall share ratably in
any distribution of the remaining assets and funds of the Company in proportion
to the respective amounts which would otherwise be payable in respect of the
shares held by them upon such distribution if all amounts payable on or with
respect to said shares were paid in full.
 
     (c) The holders of Series A Preference Shares shall not participate with
the holders of the Shares Junior to the Series A Preferred in the distribution
of any assets of the Company in excess of the aggregate Series A Liquidation
Value of the outstanding Series A Preference Shares.
 
     (d) The amalgamation of the Company into or with another company or
corporation, the amalgamation of any other company or corporation into or with
the Company, or the sale, conveyance, mortgage, pledge or lease of all or
substantially all the assets of the Company shall not be deemed to be a
liquidation, dissolution or winding up (or similar procedure) of the Company for
purposes of this Section 3.
 
     4.  Voting.
 
     (a) Except as otherwise provided by the Bye-laws (including Bye-law 12(3))
or as set forth below, each issued and outstanding Series A Preference Share
shall entitle the holder thereof to seven votes at each general meeting of the
Company with respect to any and all matters presented to the Members of the
Company for their action or consideration; provided, that if at any time at
which a vote is taken by the
 
                                        2
<PAGE>   3
 
Members there are greater than 2,600,000 Series A Preference Shares outstanding,
each Series A Preference Share shall entitle the holder thereof to such number
of votes as determined by dividing 18,200,000 by the number of issued and
outstanding Series A Preference Shares. Except as provided by law or by the
provisions of paragraph (b) below or by the Bye-laws, the holders of Series A
Preference Shares and of any other outstanding preference shares shall vote
together with the holders of Common Shares as a single class.
 
     (b) Notwithstanding anything in the Bye-laws to the contrary, the Company
shall not (i) amend, alter or repeal the preferences or special rights attached
to the Series A Preference Shares as set out in the Bye-laws, including this
Appendix A, or (ii) authorize or issue shares of any class or Series having any
preference or priority as to dividends or redemption or upon liquidation
superior to or on parity with the Series A Preference Shares, in each case,
without the written consent of the holders of at least 90% of the then issued
and outstanding Series A Preference Shares, given in writing, consenting
separately as a class.
 
     5.  Redemption.
 
     (a) Each issued and outstanding Series A Preference Share shall be redeemed
in full for an amount equal to the Series A Preferred Stated Value per share
plus dividends accrued but unpaid thereon pursuant to Sections 2(a) and (b)
above (and any dividends accrued but unpaid with respect to any such accrued but
unpaid dividends as a result of compounding at a quarterly rate) through the
date of such redemption, subject to adjustment in the event of any share split
or combination with respect to such shares, payable in cash on the date which is
June 17, 2007.
 
     (b) Upon the occurrence of a Change In Control Event, any holder of
outstanding Series A Preference Shares may elect to have all of its Series A
Preference Shares redeemed by giving written notice to the Company no later than
thirty (30) calendar days after written notice to such holder of such Change In
Control Event, and each Series A Preference Share as to which a holder has
elected redemption shall be redeemed in full for the sum of (i) 101% of the sum
of (A) the Series A Preferred Stated Value per share and (B) any non-cash
dividends accrued but unpaid thereon pursuant to Sections 2(a) and (b) above
(and any non-cash dividends accrued but unpaid with respect to any such accrued
but unpaid dividends as a result of compounding at a quarterly rate) through the
date of such redemption and (ii) any cash dividends accrued but unpaid thereon
pursuant to Section 2(a) and (b) above (and any cash dividends accrued but
unpaid with respect to any such accrued but unpaid dividends as a result of
compounding at a quarterly rate) through the date of such redemption, subject to
adjustment in the event of any share split or combination with respect to such
shares. For purposes of this Section 5(b), "Change in Control Event" means an
event or Series of events by which (A) any "person" or "group" (as defined in
Sections 13(d)(3) and 14(d) of the United States Securities Exchange Act of
1934, as amended (the "Exchange Act"), other than one or more Specified Holders
or an underwriter engaged in a firm commitment underwriting in connection with a
public offering of the Voting Stock (as defined below) of the Company, is or
becomes the "beneficial owner" (as defined under Rule 13d-3 of the Exchange

individuals who at the beginning of such period constituted the Board (together
with any new Directors (x) whose election by the Board or whose nomination for
election by the Members of the Company was approved by a vote of 66 2/3% of the
Directors of the Company then still in office who were either Directors at the
beginning of such period or whose election or nomination for election was
previously so approved or (y) were designated by one or more Specified Holders
(provided that, in the case of a designation by other holders in addition to
Specified Holders, such new Director was designated by Specified Holders
sufficient to make such designation without the approval or votes of such other
holders) pursuant to Bye-law 12(2) or 12(3)) shall cease for any reason to
constitute 66 2/3% of the Directors of the Company then still in office;
provided that, in the event that a "person" or "group" (as defined in Section
13(d)(3) and 14(d) of the Exchange Act), other than one or more Specified
Holders acting pursuant to Bye-law 12(2) or 12(3), that is the "beneficial
owner" (as defined under Rule 13d-3 under the Exchange Act), directly or
indirectly, of less than 35% of the Voting Stock of the Company is able to elect
a majority of the Board of Directors of the Company pursuant to an agreement
with the Company, a Change In Control Event shall be deemed to have occurred; or
(C) the Company consolidates with or amalgamates into, or conveys, transfers or
leases all or substantially all of its assets to any Person, or any Person
consolidates with or amalgamates into the Company, in either event pursuant to a
                                        3
<PAGE>   4
 
transaction in which any Voting Stock of the Company issued and outstanding
immediately prior to the effectiveness thereof is reclassified or changed into
or exchanged for cash, securities or property, unless (i) such Change In Control
Event arises from a transaction between the Company and a Restricted Subsidiary
thereof, or (ii) such Change In Control Event arises from a transaction
involving an exchange of Voting Stock by the holders of the Voting Stock of the
Company at such time for Voting Stock of a surviving entity immediately
following which such holders own at least 50% of the outstanding Voting Stock of
such surviving entity and upon consummation of which none of the events
described in clause (A) or (B) shall have occurred in respect of such surviving
entity.
 
     (c) On or after June 17, 2002, all or a portion of the issued and
outstanding Series A Preference Shares may be redeemed in cash, at the Company's
option and in its sole discretion, at any time or from time to time (provided
such time is during a Business Day) upon ten calendar days' prior written notice
to the holders thereof, and each Series A Preference Share so redeemed shall be
redeemed for the sum of (i) the applicable redemption percentage (as set forth
below) of the sum of (A) the Series A Preferred Stated Value per share and (B)
any non-cash dividends accrued but unpaid thereon pursuant to Sections 2(a) and
(b) above (and any non-cash dividends accrued but unpaid with respect to any
such accrued but unpaid dividends as a result of compounding at a quarterly
rate) through the date of redemption and (ii) any cash dividends accrued but
unpaid thereon pursuant to Sections 2(a) and (b) above (and any cash dividends
accrued but unpaid with respect to any such accrued but unpaid dividends as a
result of compounding at a quarterly rate) through the date of such redemption,
subject to adjustment in the event of any share split or combination with

     (d) Notwithstanding the foregoing, on and prior to June 17, 2000, up to 35%
of the issued and outstanding Series A Preference Shares may be redeemed in
cash, at the Company's option and in its sole discretion, at any time or from
time to time (provided such time is during a Business Day) upon ten calendar
days' prior written notice to the holders thereof, and each Series A Preference
Share so redeemed shall be redeemed for the sum of (i) 120% of the sum of (A)
the Series A Preferred Stated Value per share and (B) any non-cash dividends

Section 5(d) shall only be made with the net proceeds from one or more public
offerings in the United States of the Company's shares registered with the

5, other than Section 5(b), shall be made pro rata from among the registered
holders of such shares then issued and outstanding and with ten calendar days'
prior notice to such registered holders.
 
     (f) Notwithstanding any other provision of this Section 5, any redemption
pursuant to this Section 5 shall be subject to the Company being in compliance
with the Act as determined by the Board. If the Company is unable, as determined
by the Board, to redeem any Series A Preference Shares pursuant to this Section
5 because such redemption would violate the applicable laws of Bermuda, then the
Company shall redeem such Series A Preference Shares as soon thereafter as
redemption would not violate such laws. Any Series A Preference Shares that are
redeemed shall be permanently retired and shall no longer be deemed
 
                                        4

issued and outstanding and shall not under any circumstances be reissued, and
the Company may from time to time take such appropriate corporate action as may
be necessary to reduce the number of authorized Series A Preference Shares
accordingly.
 
     6.  Dividend and Redemption Preferences.
 
     (a) For so long as any of the Series A Preference Shares remains
outstanding, the Company shall not (i) purchase, redeem or otherwise acquire any
Shares Junior to the Series A Preferred (other than (1) Series B Preference
Shares in accordance with the terms thereof in effect as of June 17, 1997 (and
not as amended thereafter) and (2) redemptions or repurchases of any Common
Shares held by directors, officers or employees of the Company and its
Subsidiaries which shares are subject to redemption or repurchase upon any such
person ceasing to be a director, officer or employee, as the case may be, of the
Company, each in accordance with the terms of any applicable agreement between
the Company and any such person or the terms of any agreement or plan pursuant
to which such shares were issued, provided that such repurchases and
redemptions, in the aggregate, are in respect of no more than 10% of the number
of Common Shares issued and outstanding on June 17, 1997 (or the equivalent
number of any other securities into which or for which the Common Shares may be
converted or exchanged as set forth in the Bye-laws) and are redeemed or
repurchased for an amount not in excess of the fair market value at the time of
redemption or repurchase) or (ii) declare or pay or set apart for payment any
dividend on or make any distribution to Shares Junior to the Series A Preferred,
whether in cash or other property, other than dividends payable in Shares Junior
to the Series A Preferred.
 
     (b) For so long as (i) on or after June 17, 2007, the Company shall have
failed to redeem Series A Preference Shares pursuant to Section 5(a)
(notwithstanding Section 5(f)) or (ii) there are any unpaid (cash or non-cash)

                  SERIES B CUMULATIVE VOTING PREFERENCE SHARES
 
     1.  Designation and Number.  The Series B Preference Shares shall be a
separate Series of Preference Shares in the Company and shall be designated the
Series B Cumulative Voting Preference Shares, par value US $0.01 per share (the
"Series B Preference Shares"); and the number of shares designated the Series B
Preference Shares shall be initially 10,000,000; provided, that there shall no
more than 1,600,000 shares issued and outstanding at any one time other than as
dividends on the Series B Preference Shares, in connection with a Commitment
Draw or in exchange for outstanding Series B Preference Shares.
 
     2.  Dividends.
 
     (a) Subject to the provisions of Section 2(b) of this Appendix B, Section
6(a)(ii) of Appendix A and Section 7 of Appendix D to the Bye-laws, the holders
of Series B Preference Shares shall be entitled to receive, when and as
declared, out of the net profits or surplus of the Company legally available
therefor, dividends per share at the rate of 7.00% per annum (the "Series B
Preferred Dividend Rate") based on the Series B Preferred Stated Value (as
defined in Section 3(a) of this Appendix B), payable as the Board may determine;
provided, that such dividends accruing on or prior to June 17, 2007 and so long
as any Series A Preference Shares are outstanding shall be payable only in
Series B Preference Shares (with each share being valued for this purpose at the
Series B Preferred Stated Value) and such dividends accruing thereafter shall be
payable only in cash. Subject to Section 6(a)(ii) of Appendix A and Section 7 of
Appendix D to the Bye-laws, the Board shall determine to pay, and shall set
apart for or pay, such dividends to holders of the Series B Preference Shares
after any dividends then due upon the Series A Preference Shares, the Series C
Preference Shares and any other shares ranking on liquidation senior to the
Series B Preference Shares (such shares being referred to hereinafter
collectively as "Shares Senior to the Series B Preferred") shall be set apart
for or paid upon the Shares Senior to the Series B Preferred and before any
dividends (other than dividends payable in Shares Junior to the Series B
Preferred (as defined below)) shall be set apart for or paid upon the Common
Shares or any other shares ranking on liquidation junior to the Series B
Preference Shares (such shares being referred to hereinafter collectively as
"Shares Junior to the Series B Preferred") in any year. All dividends declared
upon Series B Preference Shares shall be declared pro rata per share.
 
     (b) Dividends on the Series B Preference Shares shall be fully cumulative,
whether or not in any fiscal year there shall be net profits or surplus
available for the payment of dividends in such fiscal year, so that, if in any
fiscal year or years, dividends in whole or in part are not paid upon the Series
B Preference Shares, unpaid dividends shall accrue quarterly at the Series B
Preferred Dividend Rate and be compounded quarterly. Dividends on the Series B
Preference Shares shall accrue at the Series B Preferred Dividend Rate based on
the actual number of days elapsed over a year of 360 days from the date of
issuance of such shares through and until the redemption of such shares.
 
     3.  Liquidation, Dissolution or Winding Up.
 
     (a) In the event of any voluntary or involuntary liquidation, dissolution
or winding up of the Company or similar procedures affecting the Company, and
after the Company has paid or set aside all amounts due to creditors and the
holders of the Shares Senior to the Series B Preferred and any dividends accrued
but unpaid on the Series B Preference Shares pursuant to Sections 2(a) and (b)
above (and any dividends accrued but unpaid thereon with respect to any such
accrued but unpaid dividends as a result of compounding at a quarterly rate)
through the date of such liquidation, dissolution or winding up (or similar
procedure), the holders of Series B Preference Shares then issued and
outstanding shall be entitled, on a pro rata per share basis, to be paid out of
the assets of the Company available for distribution to its Members, after the
Company has paid or set apart for payment all amounts due to creditors and the
holders of Shares Senior to the Series B Preferred and before any payment shall
be made by the Company to the holders of Shares Junior to the
<PAGE>   7
 
Series B Preferred, an amount equal to U.S.$25.00 (the "Series B Preferred
Stated Value") per Series B Preference Share, subject to adjustment in the event
of any share split or combination with respect to such shares. The aggregate of
all liquidation payments to which the holder of a Series B Preference Share
shall become entitled under this Section 3 with respect to each Series B
Preference Share held by it shall be referred to as its "Series B Liquidation
Value."
 
     (b) If upon any such liquidation, dissolution or winding up of the Company
(or similar procedure affecting the Company) the remaining assets of the Company
available for the distribution to its Members shall be insufficient to pay the
holders of Series B Preference Shares the full Series B Liquidation Value for
each Series B Preference Share held by such holders, the holders of Series B
Preference Shares and the holders of any class of shares ranking on liquidation
on parity with the Series B Preference Shares shall share ratably in any
distribution of the remaining assets and funds of the Company in proportion to
the respective amounts which would otherwise be payable in respect of the shares
held by them upon such distribution if all amounts payable on or with respect to
said shares were paid in full.
 
     (c) The holders of Series B Preference Shares shall not participate with
the holders of the Shares Junior to the Series B Preferred in the distribution
of any assets of the Company in excess of the aggregate Series B Liquidation
Value of the outstanding Series B Preference Shares to the Members.
 
     (d) The amalgamation of the Company into or with another company or
corporation, the amalgamation of any other company or corporation into or with
the Company, or the sale, conveyance, mortgage, pledge or lease of all or
substantially all the assets of the Company shall not be deemed to be a
liquidation, dissolution or winding up (or similar procedure) of the Company for
purposes of this Section 3.
 
     4.  Voting.
 
     (a) Except as otherwise provided in the Bye-laws or as set forth below,
each issued and outstanding Series B Preference Share shall entitle the holder
thereof to five votes at each general meeting of Members of the Company with
respect to any and all matters presented to the Members of the Company for their
action or consideration; provided, that if at any time at which a vote is taken
by the Members there are greater than 1,600,000 Series B Preference Shares
issued and outstanding, each Series B Preference Share shall entitle the holder
thereof to such number of votes as determined by dividing 8,000,000 by the
number of issued and outstanding Series B Preference Shares. Except as provided
by law or by the provisions of paragraph (b) below or by the Bye-laws, holders
of Series B Preference Shares and of any other issued and outstanding preference
shares shall vote together with the holders of Common Shares as a single class.
 
     (b) Except as set forth in paragraph (c) below, Series B Preference Shares
issued in connection with the Commitment Draw shall not entitle the holders
thereof to any votes on matters presented to the Members of the Company for any
reason.
 
     (c) Notwithstanding anything in the Bye-laws to the contrary, the Company
shall not (i) amend, alter or repeal the preferences or special rights attached
to the Series B Preference Shares as set out in the Bye-laws, including this
Appendix B, or (ii) authorize or issue shares of any class or Series having any
preference or priority as to dividends or redemption or upon liquidation
superior to or on parity with the Series B Preference Shares (other than the
Series A Preference Shares), in each case, without the written consent of the
holders of at least 90% of the then outstanding Series B Preference Shares
including holders of Series B Preference Shares issued in connection with a
Commitment Draw, given in writing, consenting separately as a class.
 
     5.  Redemption.
 
     (a) Subject to Section 6 of Appendix A and Section 7 of Appendix D, each
issued and outstanding Series B Preference Share shall be redeemed in full for
an amount equal to the Series B Preferred Stated Value per share plus dividends
accrued but unpaid thereon pursuant to Sections 2(a) and (b) above (and any
dividends accrued but unpaid with respect to any such accrued but unpaid
dividends as a result of compounding at a quarterly rate) through the date of
such redemption, subject to adjustment in the event of any share split or
combination with respect to such shares, payable in cash on the date that is the
earliest to occur of (i) June 17, 2012, (ii) the Qualified Public Offering,
(iii) the acquisition of a majority of the issued
 
                                        2
<PAGE>   8
 
and outstanding Common Shares at the time of such acquisition by one or more
purchasers acting in concert in a single transaction or in a Series of related
transactions including, without limitation, acquisitions occasioned by a
purchase or exchange, or an amalgamation, consolidation, share acquisition or
other form of corporate reorganization in which Persons who were holders of
Common Shares immediately prior to such corporate reorganization do not,
immediately thereafter, own more than 50% of the Common Shares previous voting
power, measured immediately prior to such corporate reorganization, in the
acquiring, amalgamated, consolidated or otherwise reorganized company with
respect to its issued and outstanding voting securities; provided, however, that
the distribution of Rights pursuant to an Offering Circular dated January 21,
1999, as supplemented on February 5, 1999 and February 12, 1999, and a
Subsequent Offering (as defined in the Amended and Restated Shareholders
Agreement, dated March 31, 1999) shall not trigger a redemption under any of the
foregoing clauses (i), (ii) or (iii).
 
     (b) Any redemption of Series B Preference Shares pursuant to this Section 5
shall be made pro rata from among the registered holders of such shares then
issued and outstanding and with ten calendar days' prior notice to such holders.
 
     (c) Notwithstanding any other provision of this Section 5 and subject to
Section 6 of Appendix A and Section 7 of Appendix D, any redemption pursuant to
this Section 5 shall be subject to the Company being in compliance with the Act,
as determined by the Board. If the Company is unable, as determined by the
Board, to redeem any Series B Preference Shares pursuant to this Section 5
because such redemption would violate the applicable laws of Bermuda, then the
Company shall redeem such Series B Preference Shares as soon thereafter as
redemption would not violate such laws. Any Series B Preference Shares that are
redeemed shall be permanently retired, shall no longer be deemed outstanding and
shall not under any circumstances be reissued, and the Company may from time to
time take such appropriate corporate action as may be necessary to reduce the
number of authorized Series B Preference Shares accordingly.
 
     6.  Dividend and Redemption Preferences.
 
     (a) For so long as any of the Series B Preference Shares remains issued and
outstanding, the Company shall not (i) purchase, redeem or otherwise acquire any
Shares Junior to the Series B Preferred (other than redemptions or repurchases
of any Common Shares held by directors, officers or employees of the Company and
its Subsidiaries which shares are subject to redemption or repurchase upon any
such person ceasing to be a director, officer or employee, as the case may be,
of the Company, each in accordance with the terms of any applicable agreement
between the Company and any such person or the terms of any agreement or plan
pursuant to which such shares were issued, provided that such repurchases and
redemptions, in the aggregate, are in respect of no more than 10% of the number
of Common Shares issued and outstanding on June 17, 1997 (or the equivalent
number of any other securities into which or for which the Common Shares may be
converted or exchanged as set forth in the Bye-laws) and are redeemed or
repurchased for an amount not in excess of the fair market value at the time of
redemption or repurchase) or (ii) declare or pay or set apart for payment any
dividend on or make any distribution to Shares Junior to the Series B Preferred,
whether in cash or other property, other than dividends payable in Shares Junior
to the Series B Preferred.
 
     (b) For so long as (i) the Company shall fail to redeem Series B Preference
Shares pursuant to Section 5(a) (notwithstanding Section 5(c)) or (ii) there are
any unpaid (cash or non-cash) dividends in respect of any Series B Preference
Shares, the Company shall not declare or pay or set apart for payment dividends
(other than dividends payable in Shares Junior to the Series B Preferred) on or
make distributions to shares ranking on parity with the Series B Preference
Shares.
 
     7.  Conversion.  The Series B Preference Shares are not convertible into
any other security of the Company except as provided in Section 7(a) below.
 
     (a) All Series B Preference Shares issued and outstanding on the date of
issuance of the Series C Preference Shares (the "Series C Closing Date") shall
automatically, without any action on the part of the Company or the holder
thereof, be converted into Common Shares. The number of Common Shares into which
such Series B Preference Shares shall be converted shall be determined by
dividing (X) the Series B Preferred Stated Value per share plus dividends
accrued but unpaid on the Series B Preference Shares
 
                                        3
<PAGE>   9
 
pursuant to Sections 2(a) and (b) above (and any dividends accrued but unpaid
with respect to any such accrued but unpaid dividends as a result of compounding
at a quarterly rate) through the date of such conversion, subject to adjustment
in the event of any share split or combination with respect to such shares by
(Y) a conversion price of US$3.00 per share and rounding down to the nearest
whole share.
 
     (b) The Series B Preference Shares shall be deemed to have been converted
into Common Shares on the Series C Closing Date, and the person entitled to
receive the Common Shares issuable upon such conversion shall be deemed for all
purposes to be the record holder of such Common Shares as of the close of
business on the Series C Closing Date. Accordingly, certificates for Series B
Preference Shares outstanding immediately preceding the Series C Closing Date
shall only represent such number of Common Shares into which the Series B
Preference Shares were converted.
 
     (c) Holders of certificates for Series B Preference Shares on the Series C
Closing Date can obtain certificates for Common Shares by surrendering their
certificates for Series B Preference Shares, duly endorsed if the Company shall
so require, or accompanied by appropriate instruments of transfer satisfactory
to the Company, at the office of the transfer agent for the Series B Preference
Shares, or at such other office as may be designated by the Company, together
with written request to convert the Series B Preference Shares being surrendered
into Common Shares. Such notice shall also state the name and address in which
such holder wishes the certificate for the Common Shares issuable upon
conversion to be issued. As soon as practicable after receipt of the
certificates representing the Series B Preference Shares to be converted and the
notice of election to convert the same, the Company shall issue and deliver at
said office a certificate for the number of whole Common Shares issuable upon
conversion of the Series B Preference Shares.

     (b) The amalgamation of the Company into or with another company or
corporation, the amalgamation of any other company or corporation into or with
the Company, or the sale, conveyance, mortgage, pledge or lease of all or

     (a) Except as otherwise provided in the Bye-laws or set forth below, each

after the Company has paid or set aside all amounts due to creditors and the
holders of the Series A Preference Shares and any other shares ranking on
liquidation senior to the Series C Preference Shares through the date of such
liquidation, dissolution or winding up (or similar procedure), the holders of
Series C Preference Shares then issued and outstanding shall be entitled, on a

to the Series C Preferred"), an amount equal to (i) U.S. $1.50 (the "Series C
Preferred Stated Value") per share, subject to adjustment in the event of any

to 7.00% per annum of the Series C Preferred Stated Value, which amount shall

the immediately preceding sentence to which the holder of a Series C Preference
Share shall become entitled under this Section 3 with respect to each such
Preference Share held by it shall be referred to as its "Series C Liquidation

     (b) If, upon any such liquidation, dissolution or winding up of the Company
(or similar procedure affecting the Company), the remaining assets of the
Company available for the distribution to its Members shall be insufficient to
pay the holders of Series C Preference Shares the full Series C Liquidation
Value for each Series C Preference Share held by such holders, the holders of

corporation, the amalgamation of any other company or corporation into or with
the Company, or the sale, conveyance, mortgage, pledge or lease of all or

     (b) Notwithstanding anything in the Bye-laws to the contrary, the Company
shall not (i) amend, alter or repeal the preferences or special rights attached
to the Series C Preference Shares as set out in the Bye-laws, including this
Appendix D, or (ii) authorize or issue shares of any class or Series having any
preference or priority as to redemption or upon liquidation superior to or on
parity with the Series C Preference Shares, in each case, without the written
consent of the holders of at least 90% of the then issued and outstanding Series
C Preference Shares, given in writing, consenting separately as a class.
 
     5.  Redemption.
 
     (a) The Series C Preference Shares shall be redeemed by the Company upon a
Sale (as defined below) of the Company but only if and to the extent that the
consideration to be paid (or deemed to be paid) for each Series C Preference
Share in connection with such Sale is less than the Series C Liquidation Value.
In such case, the Company shall redeem in full each Series C Preference Share
for the Series C Liquidation Value. In the case of an asset sale as described in
clause (i) of paragraph (b) below, the consideration per share deemed to be paid
for each Series C Preference Share shall be determined by (x) dividing the
aggregate gross purchase price received by the Company in connection therewith
by the fully diluted number of Common Shares outstanding assuming conversion or
exchange of all convertible or exchangeable securities and exercise of all
warrants and other derivative securities for Common Shares and (y) multiplying
the result of the calculation in clause (x) by the number of shares into which
each Series C Preference Share is convertible at the time of the consummation of
the applicable Sale based upon the then applicable Conversion Price. Upon the
consummation of any such Sale, the Company shall promptly give notice to the
holders of Series C Preference Shares setting forth the per share consideration
payable in respect of the Series C Preference Shares calculated pursuant to the
immediately preceding sentence. Except as set forth in Section 5(c), below, the
Series C Preference Shares may not be redeemed by the holder under any
circumstances, and the redemption contemplated by this Section 5(a) shall be
made ten (10) calendar days following dispatch of such notice.
 
     (b) For purposes of this Section 5, a "Sale" of the Company shall mean, (i)
a sale or other transfer in one or a series of related transactions of all or
substantially all of the assets of the Company and its subsidiaries taken as a
whole and (ii) a merger, consolidation or amalgamation to which the Company is a
party which results in the owners of all of the Company's classes of voting
securities prior to such merger, consolidation or amalgamation owning securities
with less than 50% of the then-outstanding voting power of the surviving entity
following such merger, consolidation or amalgamation.
 
     (c) At the Maturity Date (as defined in Section 6 below), the Series C
Preference Shares shall, at the option of the Company, either (i) be redeemed
for cash in an amount per share equal to the Series C Liquidation Value or (ii)
converted in Common Shares as provided by Section 6 below. No later than 10 days
prior to the Maturity Date, the Company shall give notice to the holders of
Series C Preference Shares of the impending maturity of such shares, of whether
the Company intends to redeem such shares for cash or Common Shares, and of the
then-applicable Series C Liquidation Value or number of Common Shares into which
a Series C Preference Share is then convertible.
 
     (d) Any redemption of Series C Preference Shares pursuant to this Section 5
(other than a redemption pursuant to Section 5(c) above) shall be made pro rata
from among the registered holders of such shares then issued and outstanding and
with ten calendar days' prior notice to such registered holders.
 
     (e) Notwithstanding any other provision of this Section 5, any redemption
pursuant to this Section 5 shall be subject to the Company being in compliance
with the Act as determined by the Board. If the Company is unable, as determined
by the Board, to redeem any Series C Preference Shares pursuant to this Section
5 because such redemption would violate the applicable laws of Bermuda, then the
Company shall redeem such Series C Preference Shares as soon thereafter as
redemption would not violate such laws. Any Series C Preference Shares that are
redeemed shall be permanently retired and shall no longer be deemed
 
                                        2
<PAGE>   13
 
issued and outstanding and shall not under any circumstances be reissued, and
the Company may from time to time take such appropriate corporate action as may
be necessary to reduce the number of authorized Series C Preference Shares
accordingly.
 
     6.  Conversion.
 
     (a) For purposes of this Section 6 the following definitions shall apply:
 
          (i) "Conversion Date" shall mean the earlier to occur of the Maturity
     Date or the date upon which the Series C Preference Shares are required to
     be converted pursuant to the provisions of clause (ii) of Section 6(b)

     such sale shall have been reported. If the Company's Common Shares are not
     listed on the Nasdaq National Market on the date on which the fair market
     value is to be determined, the Board of Directors shall determine in good
     faith the fair market value in whatever manner it considers appropriate;
 
          (iv) "Issue Date" shall mean March 31, 1999; and
 
          (v) "Maturity Date" shall mean March 31, 2009.
 
     (b) The Series C Preference Shares shall automatically be converted into
Common Shares at the earlier to occur of (i) the Maturity Date, with such Series
C Preference Shares being converted in such case into such number of Common
Shares as provided in Section 6(c) below, notwithstanding the then-applicable
Conversion Price, or (ii) the issuance by the Company in one or a series of
related transactions either privately or through registered public offerings
(other than pursuant to acquisitions, mergers or other business combinations or
pursuant to stock option plans, stock purchase plans or other employee benefit
plans or arrangements) of equity securities (which, for purposes of
clarification, shall not include any debt securities convertible or exchangeable
for equity securities of the Company) resulting in aggregate gross proceeds to
the Company of at least fifty million dollars (US$50,000,000) and at a price per
share determined by a majority of the Board of Directors to be fair and
reasonable ("New Equity"), with such Series C Preference Shares being converted
in such case into such number of Common Shares as set forth in Section 6(d)
below. The Company shall deliver a notice to each holder of Series C Preference
Shares at least ten days prior to the Maturity Date or, with respect to an event
described in clause (ii) of the immediately preceding sentence, promptly upon a
determination by the Board of Directors that such event is reasonably likely to
occur. Such notice shall set forth (i) the Maturity Date or the expected closing
date of such event, as applicable and (ii) the Fair Market Value, in addition to
the items specified in Section 5(c) above.
 
     (c) If an election is not made pursuant to Section 5(c) above, at the
Maturity Date, the Series C Preference Shares shall, notwithstanding the
then-applicable Conversion Price, be converted into such number of Common
Shares, determined by dividing the Series C Liquidation Value by (x) the
Conversion Price if the Fair Market Value per Common Share at the Maturity Date
is at least U.S. $1.50 or (y) ninety-five percent (95%) of the Fair Market
Value, if the Fair Market Value per Common Share at the Maturity Date is less
than U.S. $1.50. The conversion ratio described in the preceding sentence shall
not be applicable to the conversion of the Series C Preference Shares into
Common Shares on a date prior to the Maturity Date.
 
     (d) Upon the issuance by the Company of New Equity, each Series C
Preference Share shall be converted into such number of Common Shares to be
determined by dividing the Series C Preferred Stated Value by the Conversion
Price.
 
     (e) Series C Preference Shares may be converted into Common Shares at any
time at the option of the holder at the then-applicable Conversion Price. For
purposes of conversions at the option of the holder
 
                                        3
<PAGE>   14
 
contemplated by this Section 6(e), each Series C Preference Share shall be
valued at the Series C Preferred Stated Value.
 
     (f) With respect to any conversions of securities pursuant to the preceding
paragraphs of this Section 6, the holder thereof shall surrender the
certificates therefor, duly endorsed if the Company shall so require, or
accompanied by appropriate instruments of transfer satisfactory to the Company,
at the office of the transfer agent for the Series C Preference Shares, or at
such other office as may be designated by the Company, together with written
notice that such holder irrevocably elects to convert such shares. Such notice
shall also state the name and address in which such holder wishes the
certificate for the Common Shares issuable upon conversion to be issued. As soon
as practicable after receipt of the certificates representing the Series C
Preference Shares to be converted and the notice of election to convert the
same, the Company shall issue and deliver at said office a certificate for the
number of whole Common Shares issuable upon conversion of the Series C
Preference Shares surrendered for conversion (rounding down to the nearest whole
share), to the person entitled to receive the same. The Series C Preference
Shares shall be deemed to have been converted immediately prior to the close of
business on the date such shares are surrendered for conversion and notice of
election to convert the same is received by the Company in accordance with the
foregoing provision, and the person entitled to receive the Common Shares
issuable upon such conversion shall be deemed for all purposes as the record
holder of such Common Shares as of the close of business on such date.
 
     (g) No fractional Common Shares shall be issued upon conversion of any
Series C Preference Shares. If more than one stock certificate for Series C
Preference Shares shall be surrendered for conversion at one time by the same
holder, the number of full Common Shares issuable upon conversion thereof shall
be computed on the basis of the aggregate number of shares represented by all
the certificates so surrendered. If the conversion of any Series C Preference
Shares results in a fractional Common Share, the Company shall round down to the
nearest whole share amount and issue a certificate for such whole number of
shares.
 
     (h) The Conversion Price shall be adjusted from time to time as follows:
 
          (i) In the event that the Company shall pay or make a dividend or
     other distribution on any class of Common Shares or Preference Shares
     (other than the Series C Preference Shares) of the Company in Common
     Shares, the Conversion Price in effect at the opening of business on the
     date following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction, the numerator of which
     shall be the number of Common Shares outstanding at the close of business
     on the date fixed for such determination, and the denominator of which
     shall be the sum of such number of shares and the total number of shares
     constituting such dividend or other distribution, such reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination. For purposes of this subsection, the
     number of Common Shares at any time outstanding shall not include shares
     held in the treasury of the Company or issued to the treasury as a dividend
     with respect thereto.
 
          (ii) In the event that the Company shall issue options, rights or
     warrants to any holders of any class of Common Shares or Preference Shares
     (other than the Series C Preference Shares) of the Company entitling them
     to subscribe for or purchase Common Shares or at a price per share less
     than the Conversion Price on the date fixed for the determination of
     stockholders entitled to receive such options, rights or warrants (other
     than pursuant to a dividend reinvestment plan, an employee stock option
     plan, an employee stock warrant plan or any similar plan for the benefit of
     the employees of the Company and/or its subsidiaries), the Conversion Price
     in effect at the opening of business on the day following the date fixed
     for such determination shall be reduced by multiplying such Conversion
     Price by a fraction, the numerator of which shall be the number of Common
     Shares outstanding at the close of business on the date fixed for such
     determination, and the denominator of which shall be the number of Common
     Shares outstanding at the close of business on the date fixed for such
     determination plus the number of Common Shares issuable upon exercise of
     such options, rights or warrants, such reduction to become effective
     immediately after the opening of business on the day following the date
     fixed for such determination. For the purposes of this subsection (ii), the
     number of Common Shares at any time outstanding shall not
 
                                        4
<PAGE>   15
 
     include shares held in the treasury of the Company or issuable pursuant to
     warrants held in or issued to treasury.
 
          (iii) In the event that outstanding Common Shares shall be subdivided
     into a greater number of Common Shares, the Conversion Price in effect at
     the opening of business on the day following the day upon which such
     subdivision becomes effective shall be proportionately reduced, and,
     conversely, in case outstanding Common Shares shall be combined into a
     smaller number of Common Shares, the Conversion Price in effect at the
     opening of business on the day following the day upon which such
     combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective immediately
     after the opening of business on the day following the day upon which such
     subdivision or combination becomes effective.
 
          (iv) In the event that the Company shall, by dividend or otherwise,
     distribute to any holders of any class of Common Shares or Preference
     Shares (other than the Series C Preference Shares) of the Company evidences
     of its indebtedness or assets (including (A) securities, but excluding (B)
     any rights or warrants referred to in subsection (ii) above, any dividend
     or distribution paid in cash out of the consolidated retained earnings of
     the Company and any dividend or distribution referred to in subsection (i)
     above), the Conversion Price shall be adjusted so that the same shall equal
     the price determined by multiplying the Conversion Price in effect
     immediately prior to the close of business on the date fixed for the
     determination of stockholders entitled to receive such distribution by a
     fraction, the numerator of which shall be the Fair Market Value of the
     Common Shares on the date fixed for such determination less the then fair
     market value (as determined by the Board of Directors of the Company, whose
     determination shall be conclusive and shall be described in a statement
     filed with the transfer agent for the Series C Preference Shares) of the
     portion of the evidences of indebtedness or assets so distributed
     applicable to one share of Common Shares, and the denominator of which
     shall be such Fair Market Value of the Common Shares, such adjustment to
     become effective immediately prior to the opening of business on the day
     following the date fixed for the determination of stockholders entitled to
     receive such distribution.
 
          (v) The reclassification of Common Shares into securities including
     securities other than Common Shares (other than any reclassification upon a
     consolidation or merger to which Section 6(j) below applies) shall be
     deemed to involve (A) a distribution of such securities other than Common
     Shares to all holders of Common Shares (and the effective date of such
     reclassification shall be deemed to be "the date fixed for the
     determination of stockholders entitled to receive such distribution" and
     the "date fixed for such determination" within the meaning of subsection
     (iv) above), and (B) a subdivision or combination, as the case may be, of
     the number of Common Shares outstanding immediately prior to such
     reclassification into the number of Common Shares outstanding immediately
     thereafter (and the effective date of such reclassification shall be deemed
     to be "the day upon which such subdivision became effective" or "the day
     upon which such subdivision becomes effective" as the case may be, and "the
     day upon which such combination becomes effective" within the meaning of
     subsection (iii) above).
 
          (vi) Notwithstanding the foregoing, no adjustment to the Conversion
     Price for the Series C Preference Shares shall be required unless such
     adjustment would require an increase or decrease of at least 1% in such
     price; provided, however, that any adjustments which by reason of this
     subsection (vi) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment. All calculations under
     this Section shall be made to the nearest cent or to the nearest one-
     hundredth of a share, as the case may be.
 
     (i) Whenever the Conversion Price shall be adjusted as herein provided (i)
the Company shall forthwith make available at the office of the transfer agent
for the Series C Preference Shares a statement describing in reasonable detail
the adjustment, the facts requiring such adjustment and the method of
calculation used; and (ii) the Company shall cause to be mailed by first class
mail, postage prepaid, as soon as practicable to each holder of record of Series
C Preference Shares a notice stating that the Conversion Price has been adjusted
and setting forth the adjusted Conversion Price.
 
                                        5
<PAGE>   16
 
     (j) In the event of any consolidation of the Company with, or merger of the
Company into, any other corporation (other than a merger in which the Company is
the surviving corporation and which does not result in any reclassification,
conversion, exchange or cancellation of outstanding Common Shares of the
Company) or a sale, lease or conveyance of the assets of the Company as an
entirety or substantially as an entirety, or any statutory exchange of
securities with another corporation, the holder of each share of Series C
Preference Shares shall have the right, after such consolidation, merger, sale
or exchange to convert such share only into the number and kind of shares of
stock or other securities, and the amount of cash or other property receivable
upon such consolidation, merger, sale or exchange by a holder of the number of
Common Shares issuable upon conversion of such Series C Preference Shares
immediately prior to such consolidation, merger, sale or exchange. No provision
shall be made for adjustments in the Conversion Price. The provisions of this
Section 6(j) shall similarly apply to successive consolidations, mergers, sales
or exchanges.
 
     (k) The Company shall pay any taxes that may be payable in respect of the
issuance of Common Shares upon conversion of Series C Preference Shares, but the
Company shall not be required to pay any taxes which may be payable in respect
of any transfer involved in the issuance of Common Shares in the name other than
that in which the Series C Preference Shares so converted are registered, and
the Company shall not be required to issue or deliver any such shares unless and
until the person requesting such issuance shall have paid to the Company the
amount of any such taxes, or shall have established to the satisfaction of the
Company that such taxes have been paid.
 
     (l) The Company may (but shall not be required to) make such reductions in
the Conversion Price, in addition to those required by subsections (i) through
(iv) of Section 6(h) above, as it considers to be advisable in order that
certain stock-related distributions hereafter made by the Company to its
stockholders shall not be taxable.
 
     (m) The Company shall at all times reserve and keep available out of its
authorized but unissued Common Shares the full number of Common Shares issuable
upon the conversion of all Series C Preference Shares then outstanding.
 
     7.  Dividend and Redemption Preferences
 
     (a) For so long as any of the Series C Preference Shares remains
outstanding, the Company shall not declare or pay or set apart for payment any
dividend on or make any distribution to Shares Junior to the Series C Preferred,
whether in cash or other property, including dividends payable in Shares Junior
to the Series C Preferred other than dividends on Series B Preference Shares
payable in accordance with Appendix B.
 
     (b) In the event of any default by the Company on any payment due to the
holders of Series C Preference Shares, the Company shall not (A) purchase,
redeem or otherwise acquire any Shares Junior to the Series C Preferred, (B)
declare or pay or set apart for payment dividends on or make distributions to
Shares Junior to the Series C Preferred and (C) pay or set apart for payment
dividends on any shares ranking on parity with the Series C Preference Shares.

     WHEREAS, the Common Holders and the Company desire to enter into the
agreements contained herein with respect to certain matters relating to the
operations of the Company and the disposition of Company Stock.
 
     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto hereby agree as follows:
 
1.  TRANSFERS
 
     (a) Separation of Investment Units and Resale of Securities.
 
     (i) Prior to the occurrence of a Separation Event (as defined below), no
Common Holder may transfer any Company Stock constituting a part of an
Investment Unit other than collectively as a unit with the other Common Stock,
Series B Preferred Stock and the Commitment constituting a part of such
Investment Unit. Upon the occurrence of a Separation Event, a Common Holder may
transfer some or all of the Common Stock, the Series B Preferred Stock and the
Commitment constituting an Investment Unit other than collectively as a unit,
subject to applicable restrictions on transfers of Company Stock or Units set
forth in this Agreement, the Investment Units Subscription Agreement and the
Company's Amended and Restated Bye-Laws. The non-collective transfers described
in the immediately preceding sentence are referred to herein as the "Separate
Transfers". As used herein, the phrase "Separation Event" means the earlier to
occur of (x) a Trigger Event, provided that the Company receives written
notification from Duff & Phelps Credit Rating Company ("DCR") that neither such
Trigger Event nor the Separate Transfers will cause the claims paying ability
rating of Commercial Guaranty Assurance, Ltd. to be downgraded by DCR or (y)
receipt by the Company of written notification from DCR that the Separate
Transfers will not cause DCR to downgrade CGA's claims paying ability. The
parties to this Agreement expressly agree that the Series B Conversion shall not
constitute a Separation Event. Within 10 days prior to the occurrence of each
Trigger Event, the Company shall request in writing that DCR deliver the written
notification referred to in the proviso to clause (x) above. Upon the request of
any Investment Unit holder, the Company shall request in writing that DCR
deliver the written notification specified in clause (y) above. Notwithstanding
the foregoing, prior to a Separation Event, Commitments with an aggregate value
(which value shall be determined based on the product of (A) the maximum number
of shares of Series B Preferred Stock required to be purchased pursuant to such
Commitments and (B) $25.00) of up to $7.5 million may be transferred separately
from the Common Stock and Series B Preferred Stock constituting the Investment
Units held by a Common Holder without receipt from DCR of the notices provided
above; provided, further, that Olympus Growth Fund II, L.P. and Olympus
Executive Fund, L.P. shall have the first right, prior to any other Common
Holder, to so transfer all or any portion of the Commitments that it, or its
Affiliates, own; provided, further, that if Olympus Growth Fund II, L.P. and
Olympus Executive Fund, L.P. notifies the Company prior to the occurrence of a
Separation Event
 
                                        2
<PAGE>   5
 
that it will not exercise such first right or that it will not exercise such
first right with respect to Commitments with an aggregate value of $7.5 million,
Commitments with an aggregate value equal to the difference between $7.5 million
and the aggregate value of the Commitments so transferred by Olympus Growth Fund
II, L.P. and Olympus Executive Fund, L.P. may be transferred by such Common
Holders as shall request such right on a pro rata basis based on the amount of
shares of Common Stock owned by each such requesting Common Holder, as compared
to the aggregate of all of the shares of Common Stock owned by all of the
requesting Common Holders, and as shall be approved by the Board of the Company
in its sole discretion.
 
     (ii) No Common Holder shall transfer, prior to a Separation Event, any
Investment Units or Common Stock and, after a Separation Event, any Common Stock
held by such Common Holder, whether held separately or as part of one or more
Investment Units, other than, in each case, (a) in accordance with the Company's
Amended and Restated Bye-Laws and the provisions of this Section 1 and Section 2
hereof and (b) in accordance with Article VII of the Investment Unit
Subscription Agreement, Article VII of the Series C Subscription Agreement,
Article VII of the Founders' Subscription Agreement or Article IV of the Warrant
Acquisition Agreement, as the case may be. Unless (x) a registration statement
is in effect with respect to the Common Stock to be transferred or (y) the
transfer is made pursuant to Rule 144 of the Securities Act, or (z) the transfer
is of Common Stock that has been transferred previously pursuant to (x) or (y),
no Common Holder shall transfer any Common Stock whether held separately or as
part of one or more Investment Units, unless the transferee of such shares has
agreed to be bound by the terms of this Agreement and has duly executed a
counterpart of this Agreement. Any transfer or purported transfer made in
violation of this Section 1 and Section 2 hereof shall be null and void and of
no effect and the Company shall cause any correction required to be made to the
register of the Members of the Company to be effected.
 
     (iii) No Series C Holder shall transfer any Series C Preferred Stock held
by such holder, other than, in each case, (a) in accordance with the Company's
Amended and Restated Bye-Laws and the provisions of this Section 1 and Section 2
hereof and (b) in accordance with Article VII of the Series C Subscription
Agreement. Unless (x) a registration statement is in effect with respect to the
Series C Preferred Stock, or (y) the transfer is made pursuant to Rule 144 of
the Securities Act, or (z) the transfer is of stock that has been transferred
previously pursuant to (x) or (y), no Series C Holder shall transfer any such
shares unless the transferee of such shares has agreed to be bound by the terms
of this Agreement and has duly executed a counterpart of this Agreement. Any
transfer or purported transfer made in violation of this Section 1 and Section 2
hereof shall be null and void and of no effect and the Company shall cause any
correction required to be made to the register of the Members of the Company to
be effected.
 
     (b) Right of First Offer.
 
     (i) Subject to subsection (vii) below, any Common Holder desiring to
transfer, prior to any Separation Event, Investment Units or Common Stock,
whether held separately or as part of one or more Investment Units and after a
Separation Event any Common Stock (hereinafter for purposes of this Section 1(b)
only, the "Securities"), held by such Common Holder (the "Seller") shall give
written notice (the "Sales Notice") to the other Common Holders that the Seller
desires to effect such a transfer (a "Sale") and setting forth the number of
Investment Units or shares of Common Stock proposed to be transferred by the
Seller.
 
     (ii) The receipt of the Sales Notice by each other Common Holder party to
this Shareholders Agreement shall constitute an offer (the "Offer") by the
Seller to sell to such Common Holder or group of Common Holders for cash the
Securities subject to the Sale, subject to the Seller's approval of the terms
and conditions of the Bid (as defined below). Each Common Holder, or any group
of one or more Common Holders, receiving an Offer shall have a 15-day period
(the "Order Period") in which to give a written notice (a "Bid") to the Seller
prior to the expiration of such 15-day period, which written notice shall set
the price per Security that such Common Holder or group of Common Holders
proposes to pay (the "Proposed Sales Price") and such other terms and conditions
it or they propose with respect to the Sale; provided, however, a Bid must be
for all of the Securities the Seller proposes to transfer as stated in the Sales
Notice.
 
     (iii) Upon the receipt of all Bids, if any, the Seller shall have the right
to solicit offers for the Securities subject to the Sale from any non-affiliated
third-party (a "Third-Party Offer") for a period of 90 days from the date the
Order Period expires. To the extent the Seller receives a Third-Party Offer and
such Third-Party
 
                                        3
<PAGE>   6
 
Offer contains a Proposed Sales Price in excess of the highest Sales Price
received by Seller pursuant to the Bids made by the Common Holders or group of
Common Holders, then Seller shall have the right to sell the Securities to the
Third-Party pursuant to its Offer. If no Bids are delivered during the Order
Period then the Seller shall be entitled to accept, in its sole discretion, any
Third-Party Offer it so chooses. If such sale pursuant to a Third-Party Offer is
not consummated within 120-days from receipt of the Third-Party Offer, and no
Bids of Common Holders are accepted by the Seller within 10 days following the
expiration of the 90-day period described in the first sentence of this
subparagraph (iii), then the provisions of this Section 1(b) shall be reinstated
as to any other transfers proposed to be made by the Seller.
 
     (iv) The Common Holders or group of Common Holders providing a Bid to the
Seller during the Order Period as to all of the Securities subject to the Sale,
and which Bid is accepted by the Seller, shall be required to purchase and pay
for all the Securities accepted pursuant to their Bid within a 30-day period
from the date on which the buying Common Holder (or group of Common Holders)
receives written notice of the Seller's acceptance of the Bid; provided that if
the purchase and sale of such Securities is subject to any prior regulatory
approval, the time period during which such purchase and sale may be consummated
shall be extended until the expiration of five Business Days after all such
approvals shall have been received.
 
     (v) Subject to the transfer restrictions of Section 1(a)(ii), the Seller
may transfer Investment Units or shares in accordance with subsection (b)(iii)
for consideration other than cash to an unaffiliated third-party only if the
Seller has first obtained and delivered to each of the Common Holders an opinion
of an independent investment banking firm of national standing indicating that
the fair market value of the per share non-cash consideration that the Seller
proposes to accept as consideration for such Investment Units or shares,
together with any per share cash consideration, is at least equal to the highest
proposed Sale Price received by the Seller pursuant to Bids made by the Common
Holders or group of Common Holders.
 
     (vi) Notwithstanding any provision of this Section 1(b), no action may be
taken by the Seller, the other Common Holders or the Company that would cause a
violation of the provisions of Section 2.
 
     (vii) The Company shall take all reasonable steps necessary to ensure
application is made for the appropriate permissions from the Bermuda authorities
in connection with any Transfer complying with this Agreement. The Company
hereby acknowledges that no prior approval of the Bermuda Monetary Authority is
necessary for any Transfer between Persons who are designated as non-residents
of Bermuda for the purposes of the Exchange Control Act, 1972.
 
     (viii) The provisions of this Section 1(b) shall not apply to:
 
          (A) a Transfer of shares of Common Stock to an Affiliate of the
     Seller;
 
          (B) a Transfer of shares of Common Stock to another Common Holder;
 
          (C) a Transfer of Investment Units to a Common Holder holding
     Investment Units;
 
          (D) a Transfer by one or more Common Holders of a majority of all
     shares of Common Stock (and, if prior to a Separation Event, Investment
     Units) then outstanding to any Person or Persons;
 
          (E) a Transfer required by the provisions of Section 1(c) or Section
     2;
 
          (F) a Transfer permitted by the provisions of Section 1(d);
 
          (G) a Transfer pursuant to an effective registration statement with
     respect to the Common Stock to be transferred; or
 
          (H) a Transfer on or after June 12, 2002; or
 
     (c) Drag Along Right.
 
     (i) If at any time and from time to time after the date of this Agreement
Common Holders holding a majority of all shares of Common Stock then issued and
outstanding (whether or not any or all of such shares are held separately or as
part of Investment Units, the "Transferring Investors") wish to Transfer in a
bona fide arm's-length sale for cash consideration all of the Common Stock (and,
if prior to a Separation Event, the
 
                                        4
<PAGE>   7
 
Investment Units) held by the Transferring Investors to any Person or Persons
who are not Affiliates of the Transferring Investors (for purposes of this
Section 1(c), the "Proposed Transferee"), the Transferring Investors shall have
the right (the "Drag-Along Right"), subject to applicable law and compliance
with Section 1(a) with respect to such Transfer, to require all (but not less
than all) other Common Holders to sell, pursuant to Section 1(c)(ii), to the
Proposed Transferee all (but not less than all) of the shares of Common Stock
(and, if prior to a Separation Event, the Investment Units) then owned by such
other Common Holders. Each Common Holder agrees to take all steps necessary to
enable such Common Holder to comply with the provisions of this Section 1(c).
 
     (ii) To exercise a Drag-Along Right, the Transferring Investors shall give
each other Common Holder and the Company a written notice (for purposes of this
Section 1(c), a "Drag-Along Notice") containing (a) the aggregate number of
shares of Common Stock (and, if prior to a Separation Event, the Investment
Units) that the Proposed Transferee proposes to acquire from the Transferring
Investors and the other Common Holders, (b) the name and address of the Proposed
Transferee and (c) the proposed purchase price, terms of payment and other
material terms and conditions of the Proposed Transferee's offer. Each Common
Holder shall thereafter be obligated, subject to applicable law, to sell all
(but not less than all) of its shares of Common Stock (and, if prior to a
Separation Event, its Investment Units) as provided in such Drag-Along Notice,
provided that the sale to the Proposed Transferee is consummated within one
hundred and twenty (120) days of delivery of the Drag-Along Notice. If the sale
is not consummated within such 120-day period, then each Common Holder shall no
longer be obligated to sell such Common Holder's shares of Common Stock (or, if
prior to a Separation Event, Investment Units) pursuant to that specific
Drag-Along Right but shall remain subject to the provisions of this Section 1(c)
with respect to any subsequent Drag-Along Rights.
 
     (d) Tag Along Right.
 
     If at any time or from time to time after the date of this Agreement one or
more Common Holders (whether or not such shares are held separately or as part
of Investment Units, the "Transferors") wish to Transfer, in one transaction or
a Series of related transactions, a majority of the then issued and outstanding
Common Stock (whether or not such shares of Common Stock are held separately or
as part of Investment Units) to any Person or Persons who are not Affiliates of
the Transferors (other than pursuant to an effective registration statement with
respect to the shares of Common Stock to be transferred or as a result of a
pledge of shares as security for a bona fide loan), such Transferors shall
notify each other Common Holder holding Common Stock (and, if prior to a
Separation Event, Investment Units) (the "Other Holders") and the Company, in
writing, of such Transfer and its terms and conditions. Within 20 days of the
date that such notice is deemed to have been given (as provided in Section 6(f)
herein) to such Other Holders, each of the Other Holders shall notify the
Transferors if it elects to participate in such Transfer. Each of the Other
Holders that so notifies the Transferors shall be obligated to sell, at the same
price and on the same terms as the Transferors, such number of shares of Common
Stock (or, if prior to a Separation Event, such number of shares of Common Stock
or Investment Units, as the case may be) equal to the number of shares of Common
Stock (or, if prior to a Separation Event, such number of shares of Common Stock
or Investment Units, as the case may be) the third party actually proposes to
purchase multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock (or, if prior to a Separation Event, such number of
shares of Common Stock or Investment Units, as the case may be) owned by such
Other Holder and the denominator of which shall be the aggregate number of
shares of Common Stock (or, if prior to a Separation Event, such number of
shares of Common Stock or Investment Units, as the case may be) held by the
Transferors and each Other Holder exercising its rights under this Section 1(d).
 
     (e) Preemption Right.
 
     If at any time from and after the date hereof, the Company proposes to
issue equity securities of any kind (the term "equity securities" shall include
for these purposes any warrants, options or other rights to acquire equity
securities or debt securities convertible into equity securities) of the Company
(except for issuances pursuant to the terms of the Stock Warrant Plans and
issuances in connection with (i) a Qualified Public Offering, (ii) a conversion
or exchange of any outstanding securities, (iii) a stock dividend, (iv) the
exercise of any right existing pursuant to any agreements in effect immediately
following June 17, 1997 to acquire
 
                                        5
<PAGE>   8
 
equity securities of the Company, including, without limitation, pursuant to the
Warrants and the Commitments, or (v) a merger, amalgamation, reclassification or
other reorganization), then, as to each Common Holder who holds Company Stock at
such time, the Company shall:
 
          (i) give written notice (the "Offer Notice") setting forth in
     reasonable detail (1) the designation and all of the terms and provisions
     of the equity securities proposed to be issued (the "Proposed Securities"),
     including, where applicable, the voting powers, preferences and relative
     participating, optional or other special rights, and the qualification,
     limitations or restrictions thereof and interest rate and maturity; (2) the
     price, if applicable, and other terms of the proposed sale or issuance of
     such securities; (3) the amount of such securities proposed to be issued;
     and (4) such other information as may be reasonably required in order to
     evaluate the proposed issuance; and
 
          (ii) offer to issue to each such Common Holder a portion of the
     Proposed Securities equal to a percentage determined by dividing (x) the
     number of shares of Common Stock held by such Common Holder (whether held
     separately or as part of one or more Investment Units) by (y) the total
     number of shares of Common Stock including those part of any Investment
     Units then issued and outstanding (the quotient of (x) and (y) with respect
     to each such Common Holder is referred to hereinafter as such Common
     Holder's "Allotted Amount").
 
     Each such Common Holder that wishes to exercise any or all of its
preemption rights hereunder must deliver a written notice (the "Election
Notice") to that effect to the Company within fifteen (15) days after the date
the Offer Notice was deemed to have been given (as provided in Section 6(f)
herein) by the Company. Each such Election Notice shall set forth (i) the
portion of such Common Holder's Allotted Amount for which such Common Holder has
elected to subscribe and (ii) the amount, if any, of additional Proposed
Securities for which such Common Holder wishes to subscribe (the "Proposed
Overallotment Amount" with respect to each such Common Holder) in the event that
all of the Proposed Securities offered or issued to the Common Holders as a
whole are not fully subscribed for; provided, however, that in no event shall
any Common Holder be permitted to subscribe for or purchase shares of Company
Stock to the extent that such Common Holder would be in violation of Section 2
of this Agreement or the Maximum Percentage limitations set forth in Bye-law
1(ac) and Bye-law 50 of the Company's Amended and Restated Bye-laws.
 
     Each Common Holder shall be entitled to subscribe for all or a portion of
its Proposed Overallotment Amount only to the extent that one or more Common
Holders does not subscribe for its full Allotted Amount. Any such
unsubscribed-for Proposed Securities ("Excess Proposed Securities") shall be
allocated pro rata (and by rounding down to the nearest whole share) among those
Common Holders electing to receive their Proposed Overallotment Amount in
proportion to the aggregate number of shares requested by them pursuant to the
Allotted Amount and Proposed Overallotment Amount; provided, however, that in no
event shall any Common Holder be permitted to subscribe for or purchase shares
of Company Stock to the extent that such Common Holder would be in violation of
Section 2 of this Agreement or the Maximum Percentage limitations set forth in
Bye-law 1(ac) and Bye-law 50 of the Company's Amended and Restated Bye-laws.
 
     Upon the expiration of the offering period described above, the Company
may, in its sole discretion, offer to sell or issue such Proposed Securities
that the Common Holders have not elected to purchase or exercise, as the case
may be, during the 180 days following such expiration, on terms and conditions
no more favorable to the prospective purchasers thereof than those offered to
such Common Holders. Any such sale or issuance of Proposed Securities may be
consummated within 60 days after the expiration of such 180-day period. Any
Proposed Securities offered, sold or issued by the Company after such 180-day
period (other than pursuant to the immediately preceding sentence) must be
reoffered to the Common Holders pursuant to this Section 1(e). The election by a
Common Holder not to exercise its preemption rights under this Section 1(e) in
any one instance shall not affect its right (other than in respect of a
reduction in its percentage holdings) as to any subsequent proposed issuance.
Any sale or issuance of such securities by the Company without first giving the
Common Holders the rights described in this Section 1(e) shall be void and of no
force and effect and the Company shall cause any correction required to be made
to the Register of the Members of the Company to be effected.
 
                                        6
<PAGE>   9
 
     The Company hereby agrees that it shall cause each of its wholly-owned
subsidiaries to comply with the terms of this Section 1(e) with respect to the
issuance of any equity securities by such subsidiary (except for issuances of
stock dividends or in connection with a merger, amalgamation, reclassification
or other reorganization).
 
     The parties to this Agreement agree that (a) for the purposes of this
Section 1(e) only, holders of Series B Preferred Stock shall be deemed to be
Common Holders with respect to the Company's offering of rights to purchase
Series C Preferred Stock, on substantially the terms set forth in the Rights
Offering Circular dated as of January 21, 1999, as supplemented on February 5,
1999 (the "Rights Offering"), it being understood that for the purposes of such
Rights Offering, the then-existing shares of Series B Preferred Stock shall be
deemed to have been converted into Series B Conversion Shares at the rate set
forth in the Company's Amended and Restated Bye-laws and (b) the Rights Offering
shall be deemed to be in full compliance with this Section 1(e).
 
     The parties to this Agreement further agree that upon consummation of the
Rights Offering, the Company may, in the discretion of the Company's Board of
Directors, issue and sell additional equity securities of the Company at no less
than the per share price of Common Stock contemplated by the Rights Offering
(based upon the conversion price of the Series C Preferred Stock of $1.50 as of
the date of its original issuance and a purchase price of $1.50 per share of
Series C Preferred Stock) and for aggregate gross proceeds equal to the
difference between $200 million and the gross proceeds raised pursuant to the
Rights Offering (the "Subsequent Offering"), and that the Common Holders and
Series B Holders hereby consent to such Subsequent Offering and waive, for one
year following the consummation of the Rights Offering (and for an additional 60
days, as set forth above in this Section 1(e), if necessary, for the Company to
consummate the transactions contemplated in such Subsequent Offering), their
preemption rights contained in this Section 1(e) with respect to any such
Subsequent Offering.
 
     (f) Regulatory Transfer.
 
     If a Common Holder reasonably determines and delivers written notice to the
Company that its holding of shares of Company Stock (x) has resulted in a
violation of any law or governmental rule, regulation, order or decree to which
such Common Holder is subject, or (y) has caused such Common Holder to become
subject to and be required to comply with any law, regulation, order or decree
to which it was not theretofore subject, the result of which violation or
subjection and compliance, as the case may be, would be materially adverse to
such Common Holder, the Company shall use its commercially reasonable efforts,
after such Common Holder has complied with Section 1(b), to locate on behalf of
the Common Holder a purchaser for all or part of the Company Stock held by such
Common Holder.
 
     (g) Termination of Rights.
 
     The rights and obligations provided by this Section 1 shall expire upon a
Qualified Public Offering.
 
2.  RESTRICTIONS ON STOCK OWNERSHIP
 
     (a) Share Ownership Limitations.
 
     (i) Notwithstanding any other provision of this Agreement, no Common Holder
may transfer, purchase or acquire (except by operation of law) any Company
Stock, directly, indirectly or by attribution, or take any other action if such
transfer, purchase, acquisition or other action would cause any Person to (A)
become a 10% Investor (as defined in Section 5(a) hereof) or (B) own more than
20% of the issued and outstanding shares of Common Stock calculated on a fully
diluted basis (a "20% Common Investor"). For avoidance of doubt, it is agreed
that for purposes of determining whether any person is a 20% Common Investor,
such person shall be deemed to own all shares of Common Stock issuable upon
exercise of warrants, options or other similar derivative securities or issuable
upon conversion or exchange of any convertible or exchangeable security of the
Company.
 
     (ii) Without limiting Section 2(a)(i), if any Common Holder becomes a 10%
Investor or a 20% Common Investor, such Common Holder (the "Excess Investor")
shall give notice to the Company within
 
                                        7
<PAGE>   10
 
five (5) days following the date of such Common Holder's becoming aware that it
has become a 10% Investor or 20% Common Investor. Such notice shall specify the
identity of such record or beneficial owner, and such Common Holder shall
furnish to the Company such other information as the Company shall reasonably
request.
 
     (iii) Any proposed Transfer in violation of this Section (2)(a) made known
to the Company shall not be registered in the Register of Members of the
Company. If the Company learns that a Common Holder is holding Company Stock in
violation of this Section 2(a) that is registered in the Register of Members,
the Company may deregister the transfer of the Common Stock held in violation of
this Section 2(a) and register such Company Stock in the name of the Member that
transferred such Company Stock or repurchase the Company Stock held in violation
of this Section 2(a) as determined by the Board in its absolute and unfettered
discretion, subject to the restrictions on repurchase set forth in Bye-law 52(4)
of the Company's Amended and Restated Bye-laws.
 
     (iv) The Board of Directors of the Company may, in its sole discretion,
waive any of the provisions of this Section 2(a) with respect to one or more
Common Holders.
 
     (b) Prompt Disposition of Shares.
 
     If a Common Holder takes any action resulting in a violation of the
provisions of Section (2)(a) and the Company determines, pursuant to a
Super-Majority Board Action (as defined in Section 5(a) hereof), that the
disposition of Company Stock by such Excess Investor is in the interest of the
Company and its Members, (i) the Company shall require the Excess Investor to
dispose of a number of shares of Company Stock such that such Excess Investor or
other Person, as the case may be, no longer exceeds the limitations set forth in
Section (2)(a) and (ii) each Common Holder hereby agrees, if so required by the
Company, to sell such Company Stock as the Company may direct in accordance with
Section 2(c). Any disposition pursuant to this Section (2)(b) should occur no
later than the 28th calendar day after the date on which the Excess Investor
first violated, or caused another Person to violate, the share ownership
limitations set forth in Section (2)(a) and such Excess Investor shall make all
reasonable efforts to effect such disposition within such 28-day period. The
determination of whether an Excess Investor is in violation of the share
ownership limitations of Section (2)(a) and, if so, whether such disposition is
in the interests of the Company and its members may be made on behalf of the
Company by the Board, pursuant to a Super-Majority Board Action, in its judgment
and such determination shall be binding on the Common Holders.
 
     (c) Manner of Disposition.
 
     Any Company Stock required to be disposed of pursuant to Section (2)(b)
shall (i) (x) if purchased by the Excess Investor or a Related Person from
another Common Holder or Common Holders, be resold to such other Common Holder
or Common Holders at the original purchase price and (y) each Common Holder
agrees, if applicable, to purchase such Company Stock back from the Excess
Investor as contemplated by the foregoing clause, or (ii) if otherwise acquired
by the Excess Investor, be sold to any Person subject to the restrictions of
Section (2)(a) (including, but not limited to, the Company if a sale to the
Company would not cause any Person to exceed the share ownership limitations of
Section (2)(a)), but within the time period set forth in Section (2)(b).
 
     Notwithstanding the foregoing, a holder of Series A Preferred Stock shall
not be obligated to dispose of shares of such Stock, but it may be obligated in
accordance with the foregoing to dispose of other classes of stock of the
Company.

     (i) Request for Registration.  If the Company shall receive from an
Initiating Holder, at any time after 180 days after a Qualified Public Offering,
a written request that the Company effect any registration with respect to all
or a part of the Registrable Securities, the Company will:
 
          (A) promptly give written notice of the proposed registration to all
     other Holders of Registrable Securities; and
 
                                        9
<PAGE>   12
 
          (B) as soon as practicable, use its best efforts to effect a
     registration statement, in accordance with Section 3(e), as would permit or
     facilitate the sale and distribution of all or such portion of such
     Registrable Securities as are specified in such request in accordance with
     such request, together with all or such portion of the Registrable
     Securities of any Holder or Holders joining in such request as are
     specified in a written request received by the Company within 10 Business
     Days after written notice from the Company is deemed given (as provided in
     Section 6(f) herein) under Section 3(b)(i)(A) above; provided that the
     Company shall not be obligated to effect, or take any action to effect, any
     such registration pursuant to this Section 3(b):
 
             (v) within 180 days following the effective date of any
        underwritten public offering of the Company's securities;
 
             (w) for a period of 180 days following the date of the Board
        resolution described in this clause (w), if the Company furnishes to the
        Holders requesting the filing of a registration statement pursuant to
        this Section 3(b) a certificate signed by the President or Chief
        Executive Officer of the Company stating that the Board has passed a
        resolution authorizing the Company to register any of its equity
        securities for its own account and the Company is in the process of
        effecting such registration (it being understood that the limitation
        described in this clause (w) shall not affect any Holder's rights with
        respect to a registration effected pursuant to Section 3(c));
 
             (x) in any particular jurisdiction in which the Company would be
        required as a result of such registration to (1) qualify generally to do
        business in any jurisdiction where it would not otherwise be required to
        qualify but for this clause (x), (2) subject itself to taxation or
        regulation of its insurance business in any such jurisdiction other than
        Bermuda or (3) consent to service of process in effecting such
        registration, qualification or compliance;
 
             (y) if the Registrable Securities requested by all Holders to be
        registered pursuant to such request do not (i) represent at least 10% of
        the Registrable Securities or (ii) have an anticipated aggregate public
        offering price (before any underwriting discounts and commissions) of at
        least $10,000,000.
 
     The registration statement filed pursuant to the request of the Initiating
Holders may, subject to the provisions of Section 3(b)(ii) below, include other
securities of the Company which are held by Persons who, by virtue of agreements
with the Company, are entitled to include their securities in any such
registration, but the right of such Persons to include any of their securities
in any such registration shall be subject to the limitations set forth in
Section 3(b)(ii) below.
 
     Holders holding a majority of the Registrable Securities requested to be
registered may, at any time prior to the effective date of the registration
statement relating to such registration, revoke such request, without liability
to any of the other Holders or the Other Shareholders (as defined below), by
providing a written notice to the Company revoking such request.
 
     (ii) Underwriting.  The Initiating Holders shall distribute the Registrable
Securities covered by their request by means of an underwriting (which
underwriter shall be selected by the Company and reasonably acceptable to the
Initiating Holders).
 
     If holders of Common Stock other than Registrable Securities who are
entitled, by virtue of agreements with the Company, to have Common Stock
included in such a registration (the "Other Shareholders") request such
inclusion, the securities of such Other Shareholders shall be included in the
underwriting subject to the applicable provisions of this Section 3. The Holders
whose shares are to be included in such registration and the Company shall
(together with all Other Shareholders proposing to distribute their securities
through such underwriting) enter into an underwriting agreement in customary
form with the representative of the underwriter or underwriters selected for
such underwriting by the Company and reasonably acceptable to the Initiating
Holders. Notwithstanding any other provision of this Section 3(b), if the
representative advises the Holders or the Company in writing that (i) marketing
factors require a limitation on the number of shares to be underwritten or (ii)
the inclusion of shares held by officers and directors of the Company in the
offering could, in the representative's best judgment, materially reduce the
offering price per share, then, in the case of
 
                                       10
<PAGE>   13
 
the preceding clause (i), the Common Stock held by Other Shareholders shall be
excluded from such underwriting to the extent so required by such limitations
and, in the case of the preceding clause (ii), the Common Stock held by officers
and directors of the Company shall be excluded from such underwriting to the
extent advised by the representative. If, after the exclusion of such shares,
further reductions are required to meet the limitation on the number of shares
to be underwritten as advised by the representative, the number of shares that
may be included in the underwriting by each Holder requesting inclusion in the
registration shall be reduced on a pro rata basis (based on the number of shares
held at such time by the respective Holders requesting inclusion in such
registration) by such minimum number of shares as is necessary to comply with
such limitation. If any Other Shareholder who has requested inclusion in such
registration as provided above disapproves of the terms of the underwriting,
such person may elect to withdraw therefrom by written notice to the Company,
the underwriter and the Initiating Holders. If the underwriter has not limited
the number of Registrable Securities or other securities to be underwritten, the
Company may include its securities for its own account in such registration if
the representative so agrees and if the number of Registrable Securities and
other securities which would otherwise have been included in such registration
and underwriting will not thereby be limited. Any Registrable Securities or
other securities excluded or withdrawn from such underwriting shall not be
included in such registration.
 
     (iii) Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting the filing of a registration statement pursuant to this
Section 3(b) a certificate signed by the President or Chief Executive Officer of
the Company stating that, in the good faith judgment of the Board, it would be
materially detrimental to the Company and its members for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, then the Company shall have the right to defer such
filing for a period of not more than 90 days after receipt of the request of the
Initiating Holders; provided, however, that the Company may not utilize this
right more than once in any twelve (12) month period.
 
     (c) Piggyback Registration.
 
     (i) If the Company shall determine to register any of its Common Stock
either for its own account or for the account of a holder or holders of Common
Stock (other than a registration on Form S-8 (or similar or successor form)
relating solely to stock option, stock purchase or other employee benefit plans,
or a registration on Form S-4 (or similar or successor form) relating solely to
a transaction exempt under Rule 145 of the Securities Act, or a registration on
any registration form which does not permit secondary sales or does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities), the Company
will:
 
          (A) promptly give to each of the Holders a written notice thereof
     (which shall include a list of the jurisdictions in which the Company
     intends to attempt to qualify such securities under the applicable blue sky
     or other state securities laws); and
 
          (B) include in such registration (and any related qualification under
     blue sky laws or other compliance), and in any underwriting involved
     therein, all the Registrable Securities specified in a written request or
     requests made by the Holders within fifteen (15) days after the date
     written notice described in clause (i)(A) above is deemed given (as
     provided in Section 6(f) herein) by the Company except as set forth in
     Section 3(c)(ii) below. Such written request may specify all or a part of
     the Holders' Registrable Securities.
 
     (ii) Underwriting.  If the registration of which the Company gives notice
is for a registered public offering involving an underwriting (which underwriter
shall be selected by the Company, in its sole discretion), the Company shall so
advise each of the Holders as a part of the written notice given pursuant to
Section 3(c)(i)(A). In such event, the right of each of the Holders to
registration pursuant to this Section 3(c) shall be conditioned upon such
Holders' participation in such underwriting and the inclusion of such Holders'
Registrable Securities in the underwriting to the extent provided herein. The
Holders whose shares are to be included in such registration shall (together
with the Company and the Other Shareholders distributing their Common Stock
through such underwriting) enter into an underwriting agreement in customary
form with the representative of the underwriter or underwriters selected for
underwriting by the Company. Notwithstanding any other provision of this Section
3(c), if the representative advises the Holders
 
                                       11
<PAGE>   14
 
or the Company in writing that (i) marketing factors require a limitation on the
number of shares to be underwritten or (ii) the inclusion of shares held by the
officers and directors of the Company in the offering could, in the
representative's best judgment, materially reduce the offering price per share,
then, in the case of the preceding clause (i), the Common Stock held by Other
Shareholders shall be excluded from such underwriting to the extent so required
by such limitations and, in the case of the preceding clause (ii), the Common
Stock held by officers and directors of the Company shall be excluded from such
underwriting to the extent so advised by the representative. If, after exclusion
of such shares, further reductions are required to meet the limitation on the
number of shares to be underwritten as advised by the representative, the number
of shares that may be included in the underwriting by each Holder requesting
inclusion in such registration shall be reduced, on a pro rata basis (based on
the number of shares held at such time by the respective Holders requesting
inclusion in such registration), by such minimum number of shares as is
necessary to comply with such limitation (it is hereby understood that the
foregoing shall not be a limitation on the number of shares of Common Stock to
be registered by the Company). If any of the Holders or any officer, director or
Other Shareholder disapproves of the terms of any such underwriting, he may
elect to withdraw therefrom by written notice to the Company and the
underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall not be included in such registration.
 
     (iii) Number.  Each of the Holders shall be entitled to have its shares
included in an unlimited number of registrations pursuant to this Section 3(c).
 
     (d) Expenses of Registration.
 
     Upon the exercise of registration rights set forth in this Section 3, the
Company shall pay all Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to this Section 3, provided
that such expenses shall not include Selling Expenses which shall be borne by
the Holders of the securities so registered pro rata on the basis of the number
of their shares so registered; provided, however, that the Company shall not
otherwise be required to pay any Registration Expenses if, as a result of the
withdrawal of a request for registration by any of the Holders, as applicable,
including, without limitation, as provided in the last paragraph of Section
3(b)(i), the registration statement does not become effective, in which case
each of the Holders and Other Shareholders requesting registration and
thereafter withdrawing its request for registration shall bear such Registration
Expenses pro rata on the basis of the number of its shares so included in the
registration request (it is hereby understood that this proviso shall not apply
to a withdrawal of a registration being effected pursuant to Section 3(c));
provided, further, however, that the Company shall not otherwise be required to
pay any Registration Expenses after the Company has effected four (4)
registrations pursuant to Section 3(b) requested by an Initiating Holder and
such registrations have been declared or ordered effective and the sales of such
Registrable Securities shall have closed.
 
     (e) Registration Procedures.
 
     In the case of each registration effected by the Company pursuant to
Section 3, the Company will keep the Holders requesting inclusion in such
registration advised in writing as to the initiation of each registration and as
to the completion thereof. In connection with any offering of Registrable
Securities registered pursuant to clause (b) or (c) of this Section 3, the
Company shall use its best efforts to obtain all necessary permissions from the
Bermuda governmental authorities and, upon obtaining such permission, at its
expense, the Company shall:
 
          (i) prepare and file with the Commission, as promptly as practical
     after receipt of a request for registration pursuant to this Section 3, a
     registration statement on any form for which the Company then qualifies,
     and which form shall be available for the sale of the Registrable
     Securities in accordance with the intended methods of distribution thereof,
     and use its best efforts to cause such registration statement to become and
     remain effective as provided herein; provided that before filing with the
     Commission a registration statement or prospectus or any amendments or
     supplements thereto, the Company will (A) furnish, to one counsel selected
     by the Holders of a majority of the Registrable Securities requested to be
     registered, copies of all such documents proposed to be filed for said
     counsel's review and comment and (B) notify each Holder of Registrable
     Securities to be registered of any stop order issued or
 
                                       12
<PAGE>   15
 
     threatened by the Commission and take all reasonable actions required to
     prevent the entry of such stop order or to remove it if entered;
 
          (ii) prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     effective for a period of one hundred and eighty (180) days or until the
     Holders have completed the distribution described in the registration
     statement relating thereto, whichever first occurs (but not before the time
     periods referred to in Section 4(3) of the Securities Act and Rule 174
     promulgated thereunder, or any successor provisions, if applicable) and
     comply with the provisions of the Securities Act with respect to the
     disposition of securities covered by such registration statement during
     such period in accordance with the intended method of disposition by
     sellers thereof set forth in such registration statement; provided,
     however, that (A) such 180-day period shall be extended for a period of
     time equal to the period, if any, during which the Holders refrain from
     selling any securities included in such registration in accordance with
     provisions of the last paragraph of this Section 3(e) and (B) in the case
     of any registration of Registrable Securities on Form S-3 which are
     intended to be offered on a continuous or delayed basis, such 180-day
     period shall be extended until all such Registrable Securities are sold,
     provided that (x) Rule 415, or any successor Rule under the Securities Act,
     permits an offering on a continuous or delayed basis and (y) the applicable
     rules under the Securities Act governing the obligation to file a
     post-effective amendment permit, in lieu of filing a post-effective
     amendment which (1) includes any prospectus required by Section 10(a)(3) of
     the Securities Act or (2) reflects facts or events representing a material
     or fundamental change in the information set forth in the registration
     statement, the incorporation in the registration statement by reference to
     periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act
     of the information specified in clauses (1) and (2) above;
 
          (iii) furnish to each underwriter, if any, and each Holder of
     Registrable Securities covered by such registration statement such number
     of copies of such registration statement, each amendment and supplement
     thereto (in each case including all exhibits thereto), and the prospectus
     included in such registration statement (including each preliminary
     prospectus) in conformity with the requirements of the Securities Act, and
     such other documents incident thereto as each of the Holders from time to
     time may reasonably request in order to facilitate the disposition of the
     Registrable Securities owned by such Holder;
 
          (iv) use its best efforts to register or qualify such Registrable
     Securities under such other state securities or "blue sky" laws of such
     jurisdictions as any Holder, and underwriter, if any, of Registrable
     Securities covered by such registration statement reasonably requests and
     do any and all other acts and things that may be reasonably necessary or
     advisable to enable such Holder and each underwriter, if any, to consummate
     the disposition in such jurisdictions of the Registrable Securities owned
     by such Holder; provided that the Company will not be required as a result
     thereof to (A) qualify generally to do business in any jurisdiction where
     it would not otherwise be required to qualify but for this clause (iv), (B)
     subject itself to taxation or regulation of its insurance business in any
     such jurisdiction other than Bermuda or (C) consent to general service of
     process in any such jurisdiction;
 
          (v) use its best efforts to cause the Registrable Securities covered
     by such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary by virtue of
     the business and operations of the Company to enable the Holder or Holders
     thereof to consummate the disposition of such Registrable Securities;
 
          (vi) immediately notify each Holder of such Registrable Securities at
     any time when a prospectus relating thereto is required to be delivered
     under the Securities Act of the happening of any event that comes to the
     Company's attention if as a result of such event the prospectus included in
     such registration statement contains an untrue statement of a material fact
     or omits to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading; and the Company
     will promptly prepare and furnish to such Holder a supplement or amendment
     to such prospectus so that, as thereafter delivered to the purchasers of
     such Registrable Securities, such prospectus will not contain an
 
                                       13
<PAGE>   16
 
     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
     not misleading;
 
          (vii) use its best efforts to cause all such Registrable Securities to
     be listed on a national securities exchange in the United States or Nasdaq
     and on each securities exchange on which similar securities issued by the
     Company may then be listed, and enter into such customary agreements
     including a listing application and indemnification agreement in customary
     form, and, subject to Bermuda law, to provide a transfer agent and
     registrar for such Registrable Securities covered by such registration
     statement no later than the effective date of such registration statement;
 
          (viii) enter into such customary agreements (including an underwriting
     agreement or qualified independent underwriting agreement, in each case, in
     customary form) and take all such other actions as the Holders of a
     majority of the Registrable Securities being covered by such registration
     statement or the underwriters retained by such Holders, if any, reasonably
     request in order to expedite or facilitate the disposition of such
     Registrable Securities, including customary representations, warranties,
     indemnities and agreements;
 
          (ix) make available for inspection, during business hours of the
     Company, by any Holder of Registrable Securities covered by such
     registration statement, any underwriter participating in any disposition
     pursuant to such registration statement, and any attorney, accountant or
     other agent retained by any such Holder or underwriter (collectively, the
     "Inspectors"), all financial and other records, pertinent corporate
     documents and properties of the Company and its subsidiaries (collectively,
     "Records"), if any, as shall be reasonably necessary to enable them to
     exercise their due diligence responsibility, and cause the Company's
     officers, directors and employees, and those of the Company's affiliates,
     if any, to supply all information and respond to all inquiries reasonably
     requested by any such Inspector in connection with such registration
     statement;
 
          (x) use its best efforts to obtain a "cold comfort" letter from the
     Company's appointed auditors in customary form and covering such matters of
     the type customarily covered by "cold comfort" letters as the Holders of a
     majority in interest of the Registrable Securities being sold reasonably
     request; and
 
          (xi) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission and all conditions imposed by
     Bermuda governmental authorities or under Bermuda law, including, without
     limitation, under the Bermuda Companies Act, and make available to the
     Holders, as soon as reasonably practicable, an earnings statement covering
     a period of at least twelve months beginning after the effective date of
     the registration statement (as the term "effective date" is defined in Rule
     158(c) under the Securities Act) which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.
 
          It shall be a condition precedent to the obligation of the Company to
     take any action with respect to any Registrable Securities that the Holder
     thereof shall furnish to the Company such information regarding the
     Registrable Securities and any other Company Stock held by such Holder and
     the intended method of disposition of the Registrable Securities held by
     such Holder as the Company shall reasonably request and as shall be
     required in connection with the action taken by the Company.
 
          Each Holder of Registrable Securities agrees that, upon receipt of any
     notice from the Company of the happening of any event of the kind described
     in Section 3(e)(vi) hereof, such Holder will forthwith discontinue
     disposition of Registrable Securities until such Holder's receipt of the
     copies of the supplemented or amended prospectus contemplated by Section
     3(e)(vi) hereof, and, if so directed by the Company (at the Company's
     expense), such Holder will deliver to the Company all copies (including,
     without limitation, any and all drafts), other than permanent file copies,
     then in such Holder's possession, of the prospectus covering such
     Registrable Securities current at the time of receipt of such notice.
 
     (f) Indemnification.
 
     (i) In the event of any registration of any shares of Company Stock under
the Securities Act pursuant to this Agreement, the Company will indemnify and
hold harmless each of the Holders of any Registrable
 
                                       14

Securities covered by such registration statement, their respective directors
and officers, general partners, limited partners and managing directors, each
other Person who participates as an underwriter in the offering or sale of such
securities and each other Person, if any, who controls, is controlled by or is
under common control with any such Holder or any such underwriter within the
meaning of the Securities Act (and directors, officers, controlling Persons,
partners and managing directors of any of the foregoing) against any and all
losses, claims, damages and liabilities (or actions in respect thereto), joint
or several, and expenses (including any amounts paid in any settlement effected
with the Company's consent, which consent will not be unreasonably withheld) to
which such Holder, any such director or officer or general or limited partner or
managing director or any such underwriter or controlling Person may become
subject under the Securities Act, United States state securities "blue sky"
laws, common law or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) or expenses arise out
of or are based upon (A) any untrue statement (or alleged untrue statement) of
any material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary, final or
summary prospectus contained therein, or any amendment or supplement thereto,
(B) any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or (C) any violation (or alleged violation) by the Company of any United States
federal, state or common law Rule or regulation applicable to the Company and
relating to action required of or inaction by the Company in connection with any
such registration, qualification or compliance. The Company will reimburse each
such Holder, director, officer, general partner, limited partner, managing
director or underwriter and controlling Person (and directors, officers,
controlling Persons, partners and managing directors of any of the foregoing)
for any legal and any other expenses reasonably incurred in connection with
investigating or defending such claim, loss, damage, liability or action;
provided, however, that the Company shall not be liable in any such case to the
extent that any such claim, loss, damage, liability (or action or proceeding in
respect thereof) or expense arises out of or is based on any untrue statement
(or alleged untrue statement) or omission (or alleged omission) made in such
registration statement or amendment or supplement thereto or in any such
preliminary, final or summary prospectus in reliance upon and in conformity with
written information furnished to the Company by such Holder in its capacity as a
Holder or any such director, officer, general or limited partner, managing
director, underwriter or controlling Person specifically stating that it is for
use therein; provided, further, however, that the Company shall not be liable to
any Holder, any Person who participates as an underwriter in the offering or
sale of Registrable Securities, if any, or any other Person, if any, who
controls such underwriter within the meaning of the Securities Act, pursuant to
this Section 3(f) with respect to any untrue statement or omission or alleged
untrue statement or omission made in any preliminary prospectus or the final
prospectus or the final prospectus as amended or supplemented, as the case may
be, to the extent that any such loss, claim, damage or liability of such Holder,
underwriter or controlling Person results from the fact that such Holder or
underwriter sold Registrable Securities to a Person to whom there was not sent
or given, at or prior to the written confirmation of such sale, a copy of the
final prospectus or of the final prospectus as then amended or supplemented,
whichever is most recent, if the Company has previously furnished copies thereof
to such Holder or underwriter and such final prospectus, as then amended or
supplemented, had corrected any such misstatement or omission.
 
     The indemnity provided for herein shall remain in full force and effect
regardless of any investigation made by or on behalf of such Holder or any such
director, officer, general partner, limited partner, managing director,
underwriter or controlling Person and shall survive the transfer of such
securities by such Holder.
 
     (ii) Each of the Holders will, if Registrable Securities held by it are
included in any registration statement filed in accordance with the provisions
hereof, (x) indemnify, on a several and not joint basis, the Company and its
directors, officers, controlling Persons and all other prospective sellers and
their respective directors, officers, general and limited partners, managing
directors, and their respective controlling Persons against all claims, losses,
damages and liabilities (or actions in respect thereof) and expenses to which
any such Person may become subject under the Securities Act, United States state
securities "blue sky" laws, common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof) or
expenses arise out of or are based upon (A) any untrue statement (or alleged
untrue statement) of a material fact with respect to such Holder contained in
any such registration statement,

preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto, or (B) any omission (or alleged omission) to state therein a
material fact with respect to such Holder required to be stated therein or
necessary to make the statements made by such Holder therein not misleading and
(y) reimburse the Company and its directors, officers, controlling Persons and
all other prospective sellers and their respective directors, officers, general
and limited partners, managing directors, and their respective controlling
Persons for any legal or any other expenses reasonably incurred in connection
with investigating or defending any such claim, loss, damage, liability or
action, in the case of both clause (x) and clause (y), to the extent, and only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto in reliance upon and in conformity with written information
furnished to the Company by such Holder with respect to such Holder and stated
to be specifically for use therein; provided, however, that the obligations of
each of the Holders hereunder shall be limited to an amount equal to the
proceeds to be received by such Holder from securities sold by such Holder
pursuant to such registration statement or prospectus.
 
     The indemnity provided for herein shall remain in full force and effect
regardless of any investigation made by or on behalf of the Company or any of
the Holders of Registrable Securities, underwriters or any of their respective
directors, officers, general or limited partners, managing directors or
controlling Persons and shall survive the transfer of such securities by such
Holder.
 
     (iii) Each party entitled to indemnification under this Section 3(f) (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom provided that counsel for the Indemnifying Party,
who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld) and the Indemnified Party may participate in such
defense at such party's expense (unless the Indemnified Party shall have
reasonably concluded that there may be a conflict of interest between the
Indemnifying Party and the Indemnified Party in such action, in which case the
fees and expenses of the Indemnified Party's counsel shall be at the expense of
the Indemnifying Party and shall be reimbursed as they are incurred); and
provided, further, that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 3 except to the extent the Indemnifying Party is actually
materially prejudiced thereby. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as a term thereof the giving by the claimant or plaintiff to such
Indemnified Party of an unconditional release from all liability with respect to
such claim or litigation. Each Indemnified Party shall promptly furnish such
information regarding itself or the claim in question as an Indemnifying Party
may reasonably request in writing and as shall be reasonably required in
connection with the defense of such claim and litigation resulting therefrom.
 
     (iv) In order to provide for a just and equitable contribution in
circumstances in which the foregoing indemnity agreements provided for in this
Section 3(f) is for any reason held to be unenforceable although applicable in
accordance with its terms, the Company and the Holders shall contribute to the
aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by such indemnity agreement in such proportion as shall be
appropriate to reflect (A) the relative benefits received by the Company, on the
one hand, and the Holders of the Registrable Securities included in the offering
on the other hand, from the offering of the Registrable Securities and any other
securities included in such offering, and (B) the relative fault of the Company,
on the one hand, and the Holders of the Registrable Securities included in the
offering, on the other, with respect to the statements or omissions that
resulted in such loss, liability, claim, damage or expense, or action in respect
thereof, as well as any other relevant equitable considerations; provided,
however, that no Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to a
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The relative fault 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
 
                                       16
<PAGE>   19
 
information supplied by the Company or the Holders of the Registrable
Securities, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holders of the Registrable Securities agree that it would
not be just and equitable if a contribution pursuant to this Section 3(f) were
to be determined by pro rata allocation or by any other method of allocation
that does not take into account the equitable considerations referred to herein.
Notwithstanding anything to the contrary contained herein, the Company and the
Holders agree that any contribution required to be made by a Holder pursuant to
this Section 3(f) shall not exceed the net proceeds from the offering of
Registrable Securities (before deducting expenses) received by such Holder with
respect to such offering. For purposes of this Section 3(f), each Person, if
any, who controls a Holder within the meaning of Section 15 of the Securities
Act shall have the same rights to contribution as such Holder, and each director
of the Company, each officer of the Company who signed the registration
statement, and each Person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act shall have the same rights to contribution
as the Company.
 
     (v) The foregoing indemnity agreements of the Company and the Holders are
subject to the condition that, insofar as they relate to any loss, claim,
liability or damage made in a preliminary prospectus but eliminated or remedied
in the amended prospectus on file with the Commission at the time the
registration statement in question becomes effective or the amended prospectus
filed with the Commission pursuant to Commission Rule 424(b) (the "Final
Prospectus"), such indemnity agreements shall not inure to the benefit of any
underwriter if a copy of the Final Prospectus was furnished to the underwriter
and was not furnished to the Person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.
 
     (g) Information by the Holders.
 
     Each of the Holders and each Other Shareholder holding Company Stock
included in any registration shall furnish to the Company such information
regarding such Holder or Other Shareholder and the distribution proposed by such
Holder or Other Shareholder as the Company may reasonably request in writing and
as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Section 3.
 
     (h) Rule 144 Reporting.
 
     With a view to making available the benefits of certain rules and
regulations of the Commission which may permit the sale of the restricted
securities to the public without registration, the Company agrees to:
 
          (A) make and keep public information available as those terms are
     understood and defined in Rule 144 under the Securities Act, at all times
     from and after the effective date of the first registration statement under
     the Securities Act filed by the Company for an offering of its securities
     to the general public;
 
          (B) use its best efforts to file with the Commission in a timely
     manner all reports and other documents required of the Company under the
     Securities Act and the Exchange Act at any time after it has become subject
     to such reporting requirements; and
 
          (C) so long as any Holder owns any Registrable Securities, furnish to
     such Holder upon request a written statement by the Company as to its
     compliance with the reporting requirements of Rule 144 under the Securities
     Act (at any time from and after the effective date of the first
     registration statement filed by the Company for an offering of its
     securities to the general public), and of the Securities Act and the
     Exchange Act (at any time after it has become subject to such reporting
     requirements), a copy of the most recent annual or quarterly report of the
     Company, and such other reports and documents so filed as such Holder may
     reasonably request in availing itself of any Rule or regulation of the
     Commission allowing such Holder to sell any such securities without
     registration.
 
     (i) "Market Stand-off" Agreement.
 
     (i) If any registration of Common Stock (or other securities) of the
Company shall be in connection with an underwritten public offering, each Holder
of Registrable Securities agrees not to effect any sale or
 
                                       17
<PAGE>   20
 
distribution, including any private placement or any sale pursuant to Rule 144A
under the Securities Act (or any successor provision) or otherwise or any sale
pursuant to Rule 144 under the Securities Act (or any successor provision),
under the Securities Act of any Registrable Securities, other than by pro-rata
distribution to its shareholders, partners or other beneficial holders, and not
to effect any such sale or distribution of any other equity security of the
Company or of any security convertible into or exchangeable or exercisable for
any equity security of the Company (in each case, other than as part of such
underwritten public offering) during the ten calendar days prior to, and during
the 180 calendar day period (or such lesser period as may be agreed upon between
such Holders and the representative of the underwriters of such offering) that
begins on the effective date of such registration statement (except as part of
such registration), without the consent of the representative of the
underwriters of such offerings; provided, however, that written notice of such
registration has been deemed given (as provided in Section 6(f) herein) to each
Holder of Registrable Securities at least two Business Days prior to the
anticipated beginning of the ten calendar day period referred to above.
 
     (ii) If requested by the representative of the underwriters, the Holders
shall execute a separate agreement to the foregoing effect. The Company may
impose stop-transfer instructions with respect to the shares (or securities)
subject to the foregoing restriction until the end of said 180-day period. The
provisions of this Section 3(ii) shall be binding upon any transferee who
acquires Registrable Securities, including, without limitation, any Holder's
shareholders, partners or other beneficial holders, whether or not such
transferee is entitled to the registration rights provided hereunder.
 
     (iii) If any registration of Registrable Securities shall be in connection
with an underwritten public offering, the Company agrees (A) not to effect any
public sale or distribution of any of its equity securities or of any security
convertible into or exchangeable or exercisable for any equity security of the
Company (other than any such sale or distribution of such securities in
connection with any amalgamation, merger or consolidation by the Company or any
Affiliate of the Company or the acquisition by the Company or an Affiliate of
the Company of the shares or substantially all the assets of any other Person or
in connection with a stock option, stock purchase or other employee benefit
plan) during the ten days prior to, and during the 180-day period (or such
lesser period as may be agreed upon between the Company and the representative
of the underwriters of such offering) which begins on the effective date of such
registration statement (except as part of such registration) without the consent
of the representative of the underwriters of such offering and (B) that any
agreement entered into after the date hereof pursuant to which the Company
issues or agrees to issue any privately placed equity securities shall contain a
provision under which the holders of such securities agree not to effect any
sale or distribution of any such securities during the period and in the manner
referred to in the foregoing clause (A) of this Section 3(i)(iii).
 
     (j) Assignability.
 
     The registration rights set forth in this Section 3 shall be assignable by
any Holder, in whole or in part, to any transferee of Registrable Securities
provided such transferee agrees to be bound by all provisions of this Agreement.
 
     (k) Termination.
 
     The registration rights set forth in this Section 3 shall not be available
to any Holder if, in the opinion of counsel to the Company, all of the
Registrable Securities then owned by such Holder could be sold in any 90-day
period pursuant to Rule 144 under the Securities Act (without giving effect to
the provisions of Rule 144(k)).
