         principal amount equal to the aggregate principal amount of all
         outstanding Senior Notes (a "Global Senior Note"), to be registered in
         the name of the Depository, or its nominee, and delivered by the
         Property Trustee to the Depository for crediting to the accounts of its
         participants pursuant to the instructions of the Administrative
         Trustees. The Company upon any such presentation shall execute a Global
         Senior Note in such aggregate principal amount and deliver the same to
         the Trustee for authentication and delivery in accordance with the
         Indenture. Payments on the Senior Notes issued as a Global Senior Note
         will be made to the Depository. The Company initially appoints The
         Depository Trust Company to act as Depository with respect to the
         Global Senior Note, if issued.

         (ii) If the Preferred Securities are held in certificated form, the
         Senior Notes shall be presented to the Trustee by the Property Trustee
         and each outstanding Preferred Security certificate will be deemed to
         represent a beneficial interest in such Senior Note in an aggregate
         principal amount equal to the aggregate Liquidation Amount of the
         Preferred Securities represented by such Preferred Security
         certificate. When the holder of a

                                       8
<PAGE>

     Preferred Security certificate presents such certificate for transfer or
     reissuance, such certificate will be canceled and a Senior Note, registered
     in the name of such holder or such holder's transferee, as the case may be,
     in an aggregate principal amount equal to the aggregate Liquidation Amount
     of the canceled certificate, will be executed by the Company and delivered
     to the Trustee for authentication and delivery in accordance with the
     Indenture. On issue of such Senior Notes, Senior Notes with an equivalent
     aggregate principal amount that were presented by the Property Trustee to
     the Trustee will be deemed to have been canceled.

     (b)  Any Global Senior Note may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Depository, by a national
securities exchange or by the National Association of Securities Dealers, Inc.
in order for the Senior Notes to be tradeable on the PORTAL Market or as may be
required for the Senior Notes to be tradeable on any other market developed for
trading of securities pursuant to Rule 144A or required to comply with any
applicable law or any regulation thereunder or with the rules and regulations of
any securities exchange upon which the Senior Notes may be listed or traded or
to conform with any usage with respect thereto, or to indicate any special
limitations or restrictions to which any particular Senior Notes are subject.

     (c)  Each Senior Note that bears or is required to bear the legend set
forth in this Section 2.04(c) (a "Restricted Security") shall be subject to the
restrictions on transfer provided in the legend set forth in this Section
2.04(c), unless such restrictions on transfer shall be waived by the written
consent of the Company, and the Holder of each Restricted Security, by such
Holder's acceptance thereof, agrees to be bound by such restrictions on
transfer. As used in this Section 2.04(c) and in Section 2.04(d), the term
"transfer" encompasses any sale, pledge, transfer or other disposition of any
Restricted Security.

     After the occurrence of a Dissolution Event and prior to the Transfer
Restriction Termination Date, any certificate evidencing a Replacement Note
shall bear a legend in substantially the following form, unless otherwise agreed
by the Company (with written notice thereof to the Trustee):

          THE SECURITIES EVIDENCED HEREBY HAVE NOT
          BEEN REGISTERED UNDER THE U.S.

          EACH PERSON TO WHOM THE SECURITY
          EVIDENCED HEREBY IS TRANSFERRED A NOTICE

          LEGEND. AT THE REQUEST OF THE HOLDER,
          THIS LEGEND WILL BE REMOVED AFTER THE
          EXPIRATION OF THE HOLDING PERIOD
          APPLICABLE TO SALES OF THE SECURITIES
          EVIDENCED HEREBY UNDER RULE 144(k) UNDER
          THE SECURITIES ACT.

     Following the Transfer Restriction Termination Date, any Senior Note or
security issued in exchange or substitution therefor (other than Senior Notes
acquired by the Company or any Affiliate) may upon surrender of such Senior Note
or security for exchange to the Trustee in accordance with the provisions of
this Section 2.04, be exchanged for a new Senior Note or Senior Notes, of like
tenor and aggregate principal amount, which shall not bear the restrictive
legend required by this Section 2.04(c).

                                      10
<PAGE>

     (d) Any Senior Note that, prior to the Transfer Restriction Termination
Date, is purchased or owned by the Company or any Affiliate thereof may not be
resold by the Company or such Affiliate unless registered under the Securities
Act or resold pursuant to an exemption from the registration requirements
thereof.

     (e) Except as provided in (f) below, a Global Senior Note may be
transferred, in whole but not in part, only to another nominee of the
Depository, or a successor Depository selected or approved by the Company or to
a nominee of such successor Depository.

     (f) If (i) the Depository notifies the Company that it is unwilling or
unable to continue as a depositary for such Global Senior Note and no successor
depositary shall have been appointed by the Company within 90 days of such
notice or (ii) the Depository, at any time, ceases to be a clearing agency
registered under the Exchange Act at which time the Depository is required to be
so registered to act as such depositary and no successor depositary shall have
been appointed by the Company within 90 days after the Company is notified of
such event, in each case, the Company will execute and the Trustee, upon written
notice from the Company and receipt of a Company Order, will authenticate and
deliver in exchange for such Global Senior Note, the Senior Notes in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Senior
Note. If (A) the Company, in its sole discretion, determines that the Senior
Notes shall no longer be represented by a Global Senior Note or (B) there shall
have occurred an Event of Default with respect to such Senior Notes, in each
case, the Company will execute and the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Company and a Company Order,
will authenticate and make available for delivery in exchange for such Global
Senior Note, the Senior Notes in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Senior Note. Such Senior Notes shall be
registered in such names and in such authorized denominations as the Depository,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall (i) deliver such Senior Notes to
the Depository for delivery to the Persons in whose names such Senior Notes are
so registered and (ii) cancel the Global Senior Note.

     (g) The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
First Supplemental Indenture or under applicable law with respect to any
transfer of any interest in any Senior Note (including any transfers between or
among beneficial owners in any Global Senior Note) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required

                                       11

by, and to do so if and when expressly required by, the terms of this First
Supplemental Indenture and the Base Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements
hereof.

     Section 2.05. Interest. (a) Interest on the principal amount of each Senior
Note will accrue and be payable at a rate (the "Interest Rate") per annum equal
to

          (i)   from and including the Closing Date to but excluding the earlier
     of (A) the Remarketing Settlement Date on which Replacement Notes are
     issued and (B) the date such principal amount is paid, LIBOR plus 150 basis
     points;

          (ii)  from and including the Remarketing Settlement Date on which
     Replacement Notes are issued to but excluding the date such principal
     amount is paid, the Winning Bid Rate; and

          (iii) notwithstanding clauses (i) and (ii) above, if the Company fails
     to pay the principal amount on the date such amount becomes due, then from
     and including such due date to but excluding the date such principal amount
     is paid, the applicable periodic Interest Rate, compounded quarterly, but
     only to the extent permitted by applicable law.

     Interest that is not paid when due will bear Additional Interest thereon
compounded quarterly at the applicable periodic Interest Rate specified above
(to the extent permitted by applicable law). The term "interest", as used
herein, includes any such Additional Interest unless otherwise stated.

     (b) Until the Remarketing Settlement Date on which Replacement Notes are
issued, interest on the Senior Notes will be payable quarterly in arrears (A) on
January 1, April 1, July 1 and October 1 of each year, commencing January 1,
2001 and (B) on such Remarketing Settlement Date (each, subject to the last
sentence of the immediately succeeding paragraph, a "Pre-Remarketing Interest
Payment Date"), and will accrue from and including the most recent date to which
interest has been paid or, if no interest has been paid, from January 1, 2001,
to but excluding the related Pre-Remarketing Interest Payment Date, except as
otherwise described below.

     The Interest Rate in effect for the period from and including the Closing
Date to but excluding January 2, 2001 shall be the rate determined by the
Calculation Agent two London Banking Days prior to Closing Date and shall equal
LIBOR plus 150 basis points. The Interest Rate in effect thereafter, for each
quarterly period from and including the immediately preceding Pre-Remarketing

                                       12
<PAGE>

Interest Payment Date to but excluding the applicable Pre-Remarketing Interest
Payment Date, shall be determined by the Calculation Agent two London Banking
Days prior to such immediately preceding Pre-Remarketing Interest Payment Date
(a "Date of Determination") and shall equal LIBOR plus 150 basis points. Upon
determination of the applicable periodic Interest Rate, the Calculation Agent
shall promptly notify the Trustee of such determination. Prior to the
Remarketing Settlement Date, the amount of interest payable for any period shall
be computed on the basis of a 360-day year and the actual number of days elapsed
in such period. If a Pre-Remarketing Interest Payment Date is not a Business
Day, then such Pre-Remarketing Interest Payment Date will be the next succeeding
Business Day, except if such Business Day is in the next succeeding calendar
month, such Pre-Remarketing Distribution Date will be the immediately preceding
Business Day.

     All percentages resulting from any calculations on the Senior Notes will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upward (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and all
dollar amounts used in or resulting from such calculation will be rounded to the
nearest cent (with one-half cent being rounded upward).

     (c) Except with respect to Replacement Notes, interest shall be paid to the
Person in whose name such Senior Note or any predecessor Senior Note is
registered on the books and records of the Company at the close of business on
the Regular Record Date for such interest installment, which shall be fifteen
(15) days prior to a Pre-Remarketing Interest Payment Date (the "Pre-Remarketing
Regular Record Date").

     (d) From and including the Remarketing Settlement Date on which Replacement
Notes are issued, interest on the Replacement Notes will be payable quarterly in
arrears (A) on January 1, April 1, July 1 and October 1 of each year, commencing
on the first such date following such Remarketing Settlement Date and (B) on the
Maturity Date (each, an "Interest Payment Date"), and will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from and including such Remarketing Settlement Date, to but excluding the
related Interest Payment Date, except as otherwise described below. From and
including such Remarketing Settlement Date, the amount of interest payable for
any quarterly period shall be computed on the basis of a 360-day year of twelve
30-day months. Except as provided in the last sentence of this paragraph, from
and including such Remarketing Settlement Date the amount of interest payable
for any period shorter than a full quarterly period for which interest is
computed will be computed on the basis of the actual number of days elapsed per
30-day month. If an Interest Payment Date is not a Business Day, then

                                       13
<PAGE>

such Interest Payment Date will be postponed to the next succeeding Business Day
(and without any interest or other payment in respect of any such delay).

     (e) Interest on Replacement Notes shall be paid to the Person in whose name
the Senior Note or any predecessor Senior Note is registered on the books and
records of the Company, at the close of business on the Regular Record Date for
such interest installment, which, in respect of (i) Senior Notes of which the
Property Trustee is the Holder or (ii) a Global Senior Note, shall be the close
of business on the Business Day next preceding that Interest Payment Date (the
"Regular Record Date"). If the Replacement Notes are not held by the Property
Trustee and are not represented by a Global Senior Note, the Regular Record Date
for such interest installment shall be fifteen (15) days prior to that Interest
Payment Date.

     (f) In the event that (i) the Property Trustee is the Holder of all of the
outstanding Senior Notes, (ii) a Tax Event in respect of the Trust shall have
occurred and be continuing and (iii) the Company shall not have (A) redeemed the
Senior Notes pursuant to Section 3.01 or (B) terminated the Trust pursuant to
Section 8.01(a)(iii) of the Trust Agreement, the Company shall pay to the Trust
(or its permitted successors or assigns under the Trust Agreement) for so long
as the Property Trustee, on behalf of the Trust (or its permitted successor or
assignee) is the registered holder of the Senior Notes, such additional amounts
as may be necessary in order that the amount of distributions (including any
Additional Distributions as defined in the Trust Agreement) then due and payable
by the Trust on the Preferred Securities and Common Securities that at any time
remain outstanding in accordance with the terms thereof shall not be reduced as
a result of any Additional Taxes (the "Additional Sums"). Whenever in this
Indenture or the Senior Notes there is a reference in any context to the payment
of principal of or interest on the Senior Notes, such mention shall be deemed to
include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not be construed as excluding Additional Sums in those
provisions hereof where such express mention is not made.

     Section 2.06. Right to Proceed. The Company acknowledges the rights of the
Holders of Preferred Securities under the Trust Agreement to take Direct Action
referred to in Section 3.08(e) thereof and Annex I thereto.

     Section 2.07. No Issuance upon the Exercise of Warrants. The Senior Notes
shall not be issuable upon the exercise of warrants.

Indenture) at any time, upon not less than 30 nor more than 60 days' notice, to

the occurrence of such Special Event (the "90 Day Period") at a redemption price

the Mandatory Redemption Price on a Pro Rata basis. The Redemption Price shall

or such earlier time as the Company determines, provided that the Company shall
by 10:00 a.m. New York City time, deposit with the Trustee an amount sufficient
to pay the Redemption Price prior to the Redemption Date.

     Section 3.02. Optional Redemption by Company. Except as provided in Section
3.01, the Senior Notes are not subject to any optional redemption by the
Company.

     Section 3.03. No Sinking Fund. The Senior Notes are not entitled to the
benefit of any sinking fund.

     Section 3.04. Mandatory Redemption upon a Qualifying Offering. If at any
time a Qualifying Offering occurs, the Company shall, upon not less than 30 nor
more than 60 days' notice (and upon at least 45 days notice to the Trustee),
redeem Senior Notes having an aggregate principal amount equal to the gross
proceeds of such Qualifying Offering (without deduction of any applicable
underwriting discounts and commissions), on the 90th day following the closing
of such Qualifying Offering, and, simultaneously with such redemption, cause a
Like Amount of the Trust Securities to be redeemed by the Trust on a Pro Rata

     Section 8.01. Effectiveness of this Article; Incorporation of Remarketing
Agreement. (a) Sections 8.02 and 8.04 shall become effective if and only if the
Senior Notes have been distributed to the holders of the Trust Securities prior
to Remarketing. Notwithstanding the foregoing, on the Remarketing Settlement
Date (except in the case of a Failed Remarketing), the certificates representing
the Senior Notes held by the Property Trustee shall be exchanged for
certificates representing the Replacement Notes.

     (b) Every Person, by virtue of having become a Holder in accordance with

and expressly made a part of this First Supplemental Indenture.

     Section 8.02. Determination of Reset Date; Remarketing.

     (a) (i) Subject to Section 8.04, if (x) the Closing Price of the Common
Shares on any Trading Day is less than the Trigger Price or (y) a Cross Default
occurs, and, in each case, the Senior Notes have been distributed to the holders
of the Trust Securities (each, a "Trigger Event"), the holders of a majority in
principal amount of the Senior Notes (the "Requesting Holders") will have the
right to require remarketing of the Senior Notes. The Requesting Holders may
exercise this right by delivering a written notice to the Remarketing Agent at
any time on or prior to the sixth Business Day following the date on which such
Trigger Event occurs. Upon the receipt of such notice, the Remarking Agent shall
immediately deliver a written notice to the Company on behalf of the Requesting
Holders (the "Remarketing Notice"). If the Requesting Holders exercise their
right to require the remarketing of the Senior Notes, the Reset Date shall be
the sixth Business Day after the date on which the Remarketing Notice is
delivered by the Remarketing Agent (the "Expected Reset Date").

          (ii)  If the Requesting Holders do not exercise their right to require
     the remarketing of the Senior Notes pursuant to Section 8.02(a)(i) above
     with respect to any Trigger Event, the Requesting Holders shall have the
     option to require the remarketing of the Senior Notes in accordance with
     Section 8.02(a)(i) with respect to any subsequent Trigger Event.

          (iii) Notwithstanding Section 8.02(a)(i):

<PAGE>

               (A) the Company may, by notice to the Remarketing Agent, direct
          that the Reset Date be delayed if the Company believes it will be
          unable to meet the conditions to Remarketing in the absence of such a
          delay; and

               (B) the Remarketing Agent may, by notice to the Company, direct
          that the Reset Date be delayed if the Remarketing Agent believes that
          a Remarketing will not be successful in the absence of such a delay;

provided that the Company and the Remarketing Agent, in either such event, will
use their reasonable best efforts to establish a delayed Reset Date that is
within five Business Days after the Expected Reset Date, but in no event later
than the 15th Business Day following the date on which the related Remarketing
Notice was delivered, or the 20th Business Day in the case of a Renewed
Remarketing to which the provisions of Section 8.04 apply (as applicable, the
"Final Reset Date").

          (iv) If the Company and the Remarketing Agent have not agreed, on or
     prior to the sixth Business Day preceding the Final Reset Date, to a Reset
     Date that is not later than the Final Reset Date, a Failed Remarketing
     shall be deemed to have occurred.

     (b) The Company shall, by notice to the Remarketing Agent no later than
five Business Days prior to the Reset Date, select and specify three Reference
Corporate Dealers. By 3:00 p.m., New York City time, on the Reset Date, the
Remarketing Agent shall request Bids from such Reference Corporate Dealers. The
Remarketing Agent or an Affiliate or Associated Person thereof (any such person,
an "Affiliated Bidder") may, at its option, enter a Bid. The Remarketing Agent
shall disclose to the Company the Bids obtained and determine the lowest Bid
Rate from among the Bids obtained on the Reset Date (the "Winning Bid Rate"). By
approximately 4:30 p.m., New York City time, on the Reset Date, the Remarketing
Agent shall notify the Company and the Trustee of the Winning Bid Rate. If on a
Reset Date, Bids are not submitted by at least two Reference Corporate Dealers,
or if the lowest Bid submitted would result in a Winning Bid Rate in excess of
the rate permitted by applicable law, the Remarketing shall be deemed to be a
Failed Remarketing on the corresponding Remarketing Settlement Date. The Winning
Bid Rate determined by the Remarketing Agent, absent manifest error, shall be
binding and conclusive upon the holders of the Senior Notes, the Company, the
Guarantor, the Trust and the Trustee.

     (c) On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "Secondary Purchaser") the Reference Corporate

                                       19
<PAGE>

Dealer providing the Bid containing the Winning Bid Rate. If the Winning Bid
Rate is specified in the Bids submitted by two or more bidders, the Remarketing
Agent shall, in consultation with the Company, designate one of such bidders as
the Secondary Purchaser.

     (d) On the Reset Date, the Secondary Purchaser shall enter into a Secondary
Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate principal amount of Senior Notes, with an
Interest Rate equal to the Winning Bid Rate and with a Maturity Date on the
Remarketed Maturity Date.

     (e) If a Remarketing has occurred pursuant to this Section 8.02 but
settlement of the purchase and sale of the Senior Notes does not occur on the
corresponding Remarketing Settlement Date, then, unless the provisions of
Section 8.04 with respect to a Renewed Remarketing shall apply, a Failed
Remarketing shall be deemed to have occurred on such Remarketing Settlement
Date.

     (f) At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay on the Remarketing Settlement Date
to the Remarketing Agent on behalf of the holders of the Senior Notes an amount
of cash equal to the Remarketing Price.

     (g) Unless otherwise agreed among the Remarketing Agent, the Paying Agent
and any Former Holder, the Remarketing Agent shall promptly pay the Remarketing
Price, less the Remarketing Fee, to the Paying Agent, acting solely as agent for
the Former Holders, and the Paying Agent shall pay such amount to the Former
Holders in the manner specified in the Base Indenture for payments of principal
and as otherwise specified herein.

     (h) The obligation of the Remarketing Agent to make payment to the Former
Holders in connection with the Remarketing shall be limited to the extent that
the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

     (i) Any outstanding Senior Notes purchased on the Remarketing Settlement
Date shall be deemed to be transferred to the Secondary Purchaser and shall be
replaced in the manner provided in Section 8.02(j); provided that if Replacement
Notes are to be issued to the Property Trustee, the Property Trustee shall
surrender its Senior Notes to the Company for cancellation at the time of
delivery of the Replacement Notes. On and after the Remarketing Settlement Date
(except in the event of (i) a Failed Remarketing or (ii) a failure by the
Company to pay on the Remarketing Settlement Date all accrued interest

                                       20
<PAGE>

(including any Additional Interest) on the Senior Notes to such Remarketing
Settlement Date), (A) the Company shall make no further payments to, and the
Company shall have no further obligations under this First Supplemental
Indenture (or the Indenture) in respect of, the holders of such replaced Senior
Notes (the "Former Holders"), (B) the Company shall only be obligated to make
payments to the holders of Replacement Notes and (C) the Senior Notes of the
Former Holders shall no longer represent an obligation of the Company, but shall
only represent a right to receive the proceeds of the Remarketing from the
Paying Agent.

     (j) The Company shall cause replacement certificates evidencing the
remarketed Senior Notes (or, if the Preferred Securities have been remarketed,
reset Senior Notes) to be executed by the Company and authenticated by the
Trustee in accordance with the provisions of Section 3.6 of the Base Indenture
(the "Replacement Notes"). If the Replacement Notes are to be purchased on the
Remarketing Settlement Date, the Replacement Notes shall be delivered to the
purchaser or purchasers of the remarketed Senior Notes in accordance with the
terms of the Secondary Purchase Agreement.

     Section 8.03. Reset of Interest Rate and Maturity Date. From and including
the Remarketing Settlement Date on which Replacement Securities are issued, if
the Senior Notes are remarketed pursuant to Article 8 hereof or the Preferred
Securities are remarketed pursuant to Article 6 of the Trust Agreement, the
Interest Rate on the Senior Notes shall be the Winning Bid Rate and the Maturity
Date shall be the Remarketed Maturity Date.

     Section 8.04. Renewed Remarketing. If a Remarketing has occurred pursuant
to Section 8.02 that would be a Failed Remarketing pursuant to Section 8.02(e),
because the purchase and sale of the Senior Notes do not take place on the
corresponding Remarketing Settlement Date, and the reason for such failure
shall, in the good faith determination of the Remarketing Agent, result from
facts or circumstances that are not due to the action or inaction of the
Company, then the provisions of Section 8.02 shall apply to a second remarketing
(a "Renewed Remarketing") of the Senior Notes, except that the Expected Reset
Date shall be the sixth Business Day following such corresponding Remarketing
Settlement Date; provided that upon the occurrence of a Failed Remarketing
pursuant to Section 8.02, only one Renewed Remarketing may occur pursuant to
this Section 8.04, and no Renewed Remarketing shall occur after the Final Reset
Date.

     Section 8.05. Failed Remarketing. The Remarketing Agent shall give notice
of any Failed Remarketing on the date such Failed Remarketing occurs, or is
deemed to occur, by 4:00 p.m., New York City time, on the date of such Failed
Remarketing, to the Company, the Trustee and the Paying Agent.

                    AUCTION RATE RESET SENIOR NOTE SERIES A

         Mutual Group Ltd., a Delaware corporation (the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to __________, or registered assigns,
the principal sum of ___________ dollars ($___________) on the Maturity Date.

         (a)      Interest on the principal amount of this Senior Note will
accrue and be payable at a rate (the "Interest Rate") per annum equal to

                  (i)  from and including the Closing Date to but excluding the
         earlier of (A) the Remarketing Settlement Date on which Replacement
         Notes are issued and (B) date on which the principal amount of this
         Senior Note becomes due upon the maturity, acceleration or redemption
         thereof, LIBOR plus 150 basis points; and

                  (ii) if the Company fails to pay the principal amount due upon
         the maturity, acceleration or redemption of this Senior Note on the
         date such amount becomes due, from and including such due date to but
         excluding the date of actual payment by the Company, the applicable
         periodic Interest Rate compounded quarterly.

         Interest that is not paid when due will bear Additional Interest
thereon compounded quarterly at the applicable periodic Interest Rate (to the
extent permitted by applicable law).

         The term "interest", as used herein, includes any Additional Interest
unless otherwise stated.

         (b) Until the Remarketing Settlement Date on which Replacement Notes
are issued, interest on this Senior Note will be payable quarterly in arrears
(i) on January 1, April 1, July 1 and October 1 of each year, commencing January
1, 2001 and (ii) on such Remarketing Settlement Date (each, subject to the last
sentence of the immediately succeeding paragraph, a "Pre-Remarketing Interest
Payment Date"), and will accrue from and including the most recent date to which
interest has been paid or, if no interest has been paid, from the Closing Date,
to but excluding the related Pre-Remarketing Interest Payment Date, except as
otherwise described below.

                                     A1-2
<PAGE>

         The Interest Rate in effect for the period from and including the
Closing Date to but excluding January 2, 2001 shall be the rate determined by
the Calculation Agent two London Banking Days prior to the Closing Date and
shall equal LIBOR plus 150 basis points. The Interest Rate in effect thereafter,
for each quarterly period from and including the immediately preceding Pre-
Remarketing Interest Payment Date to but excluding the applicable Pre-
Remarketing Interest Payment Date, shall be determined by the Calculation Agent
two London Banking Days prior to such immediately preceding Pre-Remarketing
Interest Payment Date (a "Date of Determination") and shall equal LIBOR plus 150
basis points. Prior to the Remarketing Settlement Date, the amount of interest
payable for any period shall be computed on the basis of a 360-day year and the
actual number of days elapsed in such period. If a Pre-Remarketing Interest
Payment Date is not a Business Day, then such Pre-Remarketing Interest Payment
Date will be the next succeeding Business Day, except if such Business Day is in
the next succeeding calendar month, such Pre-Remarketing Distribution Date will
be the immediately preceding Business Day.

         As used herein, "London Banking Day" means any day on which dealings in
deposits in U.S. Dollars are transacted in the London interbank market.

         All percentages resulting from any calculations on the Senior Notes
will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, with five one-millionths of a percentage point rounded upward
(e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and
all dollar amounts used in or resulting from such calculations will be rounded
to the nearest cent (with one-half cent being rounded upward).

         (c) From and including the Remarketing Settlement Date on which
Replacement Notes are issued, interest on the Replacement Notes will be payable
quarterly in arrears (i) on January 1, April 1, July 1 and October 1 of each
year, commencing on such Remarketing Settlement Date and (ii) on the Maturity
Date (each, an "Interest Payment Date"), and will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from and
including such Remarketing Settlement Date, to but excluding the related
Interest Payment Date, except as otherwise described below. From and including
such Remarketing Settlement Date, the amount of interest payable for any period
shall be computed on the basis of a 360-day year of twelve 30-day months. Except
as provided in the last sentence of this paragraph, from and including the
Remarketing Settlement Date the amount of interest payable for any period
shorter than a full quarterly period for which interest is computed will be
computed on the basis of the actual number of days elapsed per 30-day month. If
an Interest Payment Date is not a Business Day, then such Interest Payment Date

                                     A1-3
<PAGE>

will be postponed to the next succeeding Business Day (and without interest or
other payment in respect of any such delay).

         (d) Interest shall be paid to the Person in whose name this Senior Note
or any predecessor Senior Note is registered on the books and records of the
Company at the close of business on the Regular Record Date for such interest
installment, which shall be fifteen (15) days prior to a Pre-Remarketing
Interest Payment Date (the "Pre-Remarketing Regular Record Date").
Notwithstanding the foregoing, so long as the Holder of this Senior Note is the
Property Trustee, the payment of the principal of (and premium, if any) and
interest on this Senior Note will be made at such place and to such account as
may be designated by the Property Trustee.

         This Senior Note shall not be entitled to any benefit under the
Indenture hereinafter referred to, or be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed by
or on behalf of the Trustee.

         The provisions of this Senior Note are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

         IN WITNESS WHEREOF, the Company has caused this instrument to be
executed.

                           [FORM OF REVERSE OF NOTE]

         This Senior Note is one of a duly authorized series of Securities of
the Company (herein sometimes referred to as the "Senior Notes"), specified in
the Base Indenture (as defined below), all issued or to be issued in one or more
series under and pursuant to an Indenture (the "Base Indenture") dated as of
September 21, 2000, duly executed and delivered among the Company, Mutual Risk
Management Ltd., as Guarantor (the "Guarantor"), and The Chase Manhattan Bank,
as Trustee (the "Trustee"), as supplemented by the First Supplemental Indenture
dated as of September 21, 2000 among the Company, the Guarantor and the Trustee
(the Base Indenture as so supplemented, the "Indenture"), to which Indenture and
all indentures supplemental thereto reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company and the holders of the Senior Notes. By
the terms of the Indenture, the Senior Notes are issuable thereunder in series
that may vary as to amount, date of maturity, rate of interest and in other
respects as provided in the Indenture. This series of Senior Notes is limited in
aggregate principal amount as specified in such First Supplemental Indenture and
herein sometimes referred to as the "Senior Notes."

         Because of the occurrence and continuation of a Special Event or a
Qualifying Offering, in certain circumstances, this Senior Note may become due
and payable at the principal amount together with any interest accrued thereon
(including Additional Interest) (the "Redemption Price"). The Redemption Price
shall be paid prior to 12:00 Noon, New York City time, on the date of such
redemption or at such earlier time as the Company determines. If the Maturity
Date or any other date fixed for redemption of the Senior Notes is not a
Business Day, then payment of the Redemption Price or principal payable on such
date will be made on the next succeeding day that is a Business Day with
interest thereon to the date of payment; provided that, upon prior written
notice, the Company may elect to make the payment on the immediately preceding
day that is a Business Day.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Senior Notes may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company, the Guarantor
and the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Senior Notes and each other series of
Securities Outstanding and affected, to execute supplemental indentures for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the

                                              A1-6
<PAGE>

provisions of the Indenture or of modifying in any manner the rights of the
holders of such Series of Securities; provided that the Company, the Guarantor
and the Trustee may not, without the consent of the holder of each Senior Note
then Outstanding and affected thereby: (a) change the time of payment of the
principal (or any installment) of any Senior Note, or reduce the principal
amount thereof, or reduce the rate or change the time of payment of interest
thereon, or impair the right to institute suit for the enforcement of any
payment on any Senior Note when due or (b) reduce the percentage in principal
amount of the Senior Notes, the consent of whose holders is required for any
such supplemental indenture. The Indenture also contains provisions providing
that the holders of a majority in aggregate principal amount of Senior Notes
may, on behalf of the holders of all Senior Notes, waive any past default with
respect to the Senior Notes and its consequences, except a default (i) in
respect of a covenant or provision of the Indenture or of any Senior Note which
cannot be modified or amended without the consent of the holder of each
Outstanding Senior Note or (ii) in the payment of the principal of, any premium
or interest (including any Additional Interest) on, or any Additional Amounts
with respect to the Senior Notes.

         No reference herein to the Indenture and no provision of this Senior
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Senior Note at the time and place and at the rate and
in the money herein prescribed.

         As provided in the Indenture and subject to certain limitations herein
and therein set forth, this Senior Note is transferable by the registered holder
hereof on the Securities Register of the Company, upon surrender of this Senior
Note for registration of transfer at the office or agency of the Trustee in the
City and State of New York accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and the Securities Registrar duly
executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Senior Notes of authorized denominations
and for the same aggregate principal amount will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in relation thereto.

         Prior to due presentment for registration of transfer of this Senior
Note, the Company, the Guarantor, the Trustee, any Paying Agent and the
Securities Registrar may deem and treat the registered holder hereof as the
owner hereof (whether or not this Senior Note shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone other
than the Securities Registrar) for the purpose of receiving payment of or on
account of the principal

                                     A1-7
<PAGE>

hereof and premium, if any, and interest due hereon and for all other purposes,
and neither the Company nor the Guarantor nor the Trustee nor any Paying Agent
nor any Securities Registrar shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Senior Note, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         The Senior Notes of this series are issuable only in registered form
without coupons in denominations of $100,000 and any integral multiple of $1,000
thereof. A holder of Senior Notes may transfer or exchange Senior Notes held by
it only in minimum denominations of $100,000 and integral multiples of $1,000 in
excess thereof. Any attempted transfer, sale or other disposition of Senior
Notes in a denomination of less than $100,000 shall be deemed to be void and of
no legal effect whatsoever.

         All terms used in this Senior Note that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

THE INDENTURE AND THE SENIOR NOTES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS
PRINCIPLES OF CONFLICTS OF LAWS.

                               REPLACEMENT NOTE

         Mutual Group Ltd., a Delaware corporation (the "Company", which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to __________, or registered assigns,
the principal sum of ____________ dollars ($__________) on the Maturity Date.

         (a) Interest on the principal amount of this Senior Note will accrue
and be payable at a rate (the "Interest Rate") per annum equal to, from and
including the date of issuance to but excluding the date such principal amount
is paid, the Winning Bid Rate; and if the Company fails to pay the principal
amount on the date such amount becomes due, then from and including such due
date to but excluding the date such principal amount is paid, the applicable
periodic Interest Rate, compounded quarterly, but only to the extent permitted
by applicable law.

         Interest that is not paid when due will bear additional interest
thereon compounded quarterly at the applicable periodic Interest Rate (to the
extent permitted by applicable law).

         The term "interest", as used herein, includes any Additional Interest
unless otherwise stated.

         (b) From and including the Remarketing Settlement Date on which the
Replacement Notes are issued, interest on this Replacement Note will be payable
quarterly in arrears (i) on January 1, April 1, July 1 and October 1 of each
year, commencing on the first such date following such Remarketing Settlement
Date on which this Replacement Note is issued and (ii) on the Maturity Date
(each, an "Interest Payment Date"), and will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from and
including such Remarketing Settlement Date, to but excluding the related
Interest Payment Date, except as otherwise described below. The amount of
interest payable for any period shall be computed on the basis of a 360-day year
of twelve 30-day months. Except as provided in the last sentence of this
paragraph, the amount of interest payable for any period shorter than a full
quarterly period for which interest is computed will be computed on the basis of
the actual number of days elapsed per 30-day month. If an Interest Payment Date
is not a Business Day, then such

Company at the close of business on the Regular Record Date for such interest
installment, which, in respect of Senior Notes of which the Property Trustee is
the Holder or a Global Senior Note, shall be the close of business on the
Business Day next preceding that Interest Payment Date (the "Regular Record
Date"). If the Senior Notes are not represented by a Global Senior Note, the
Regular Record Date for such interest installment shall be fifteen (15) days

         This Senior Note is one of a duly authorized series of Securities of
the Company (herein sometimes referred to as the "Senior Notes"), specified in
the Base Indenture (as defined below), all issued or to be issued in one or more
series under and pursuant to an Indenture (the "Base Indenture") dated as of
September 21, 2000, duly executed and delivered among the Company, Mutual Risk
Management Ltd., as Guarantor (the "Guarantor"), and The Chase Manhattan Bank,
as Trustee (the "Trustee"), as supplemented by the First Supplemental Indenture
dated as of September 21, 2000 among the Company, the Guarantor and the Trustee
(the Base Indenture as so supplemented, the "Indenture"), to which Indenture and
all indentures supplemental thereto reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company, the Guarantor and the holders of the
Senior Notes. By the terms of the Indenture, the Senior Notes are issuable
thereunder in series that may vary as to amount, date of maturity, rate of
interest and in other respects as provided in the Indenture. This series of
Senior Notes is limited in aggregate principal amount as specified in such First
Supplemental Indenture and herein sometimes referred to as the "Senior Notes."

         Because of the occurrence and continuation of a Special Event or a
Qualifying Offering in certain circumstances, this Senior Note may become due

(including Additional Interest) (the "Redemption Price"). The Redemption Price
shall be paid prior to 12:00 Noon, New York City time, on the date of such

Date or any other date fixed for redemption of the Senior Notes is not a
Business Day, then payment of the Redemption Price or principal payable on such
date will be made on the next succeeding day that is a Business Day with
interest thereon to the date of payment; provided that, upon prior written
notice, the Company may elect to make the payment on the immediately preceding
day that is a Business Day.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Senior Notes may be

and the Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Senior Notes and each other series of
Securities Outstanding and affected, to execute supplemental indentures for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the

                                     A2-6
<PAGE>

provisions of the Indenture or of modifying in any manner the rights of the
holders of such Series of Securities; provided that the Company, the
Guarantorand the Trustee may not, without the consent of the holder of each
Senior Note then Outstanding and affected thereby: (a) change the time of
payment of the principal (or any installment) of any Senior Note, or reduce the
principal amount thereof, or reduce the rate or change the time of payment of
interest thereon, or impair the right to institute suit for the enforcement of
any payment on any Senior Note when due or (b) reduce the percentage in
principal amount of the Senior Notes, the consent of whose holders is required
for such supplemental indenture. The Indenture also contains provisions

Notes may, on behalf of the holders of all Senior Notes waive any past default
with respect to the Senior Notes and its consequences, except a default (i) in
respect of a covenant or provision of the Indenture or of any Senior Note which
cannot be modified or amended without the consent of the holder of each
Outstanding Senior Note or (ii) in the payment of the principal of, any premium
or interest (including any Additional Interest) on, or any Additional Amounts

Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and premium, if
any, and interest on this Senior Note at the time and place and at the rate and
in the money herein prescribed.

hereof on the Securities Register of the Company, upon surrender of this Senior

other governmental charge payable in relation thereto.

interest on this Senior Note, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as

default or Event of Default or impair any right consequent therefrom.

default in the payment of a Guarantee Payment, the Guarantee Trustee shall be
protected in withholding such notice if and so long as the Board of Directors,

Officers of the Guarantee Trustee in good faith determines that the withholding
of such notice is in the interests of the Holders.

         (b) The Guarantee Trustee shall not be deemed to have knowledge of any

                                   ARTICLE 3
              Powers, Duties And Rights Of The Guarantee Trustee

         Section 3.01. Powers and Duties of the Guarantee Trustee. (a) This
Guarantee Agreement shall be held by the Guarantee Trustee for the benefit of
the Holders, and the Guarantee Trustee shall not transfer this Guarantee
Agreement to any Person except a Holder exercising his or her rights pursuant to
Section 5.04(d) or 6.04(d) or to a Successor Guarantee Trustee on acceptance by
such Successor Guarantee Trustee of its appointment to act as Successor
Guarantee Trustee. The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor Guarantee Trustee, upon acceptance by such
Successor Guarantee Trustee of its appointment hereunder, and such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

         (b) If an Event of Default actually known to the Responsible Officer of
the Guarantee Trustee has occurred and is continuing, the Guarantee Trustee
shall enforce this Guarantee Agreement for the benefit of the Holders.

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.06) and is
actually known to the Responsible Officer of the Guarantee Trustee, the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

                                       7
<PAGE>

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

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

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

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

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

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

         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document believed by it to be genuine
         and to have been signed, sent or presented by the proper party or
         parties.

             (ii)  Any direction or act of the Guarantor or MRM contemplated by
         this Guarantee Agreement shall be sufficiently evidenced by an
         Officers' Certificate of the Guarantor or MRM, as the case may be,
         unless otherwise prescribed herein.

             (iii) Whenever, in the administration of this Guarantee Agreement,
         the Guarantee Trustee shall deem it desirable that a matter be proved
         or established before taking, suffering or omitting to take any action
         hereunder, the Guarantee Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and rely upon an Officers' Certificate which, upon receipt of
         such request from the Guarantee Trustee, shall be promptly delivered by
         the Guarantor.

             (iv)  The Guarantee Trustee may consult with legal counsel, and the
         advice or opinion of such legal counsel with respect to legal matters
         shall be full and complete authorization and protection in respect of
         any action taken, suffered or omitted to be taken by it hereunder in
         good faith and in accordance with such advice or opinion. Such legal
         counsel may be legal counsel to the Guarantor or MRM or any of their
         Affiliates and may be one of its employees. The Guarantee Trustee shall
         have the right at any time to seek instructions concerning the

         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such Holder
         shall have provided to the Guarantee Trustee such adequate security and
         indemnity as would satisfy a reasonable person in the position of the
         Guarantee Trustee, against the costs, expenses (including attorneys'
         fees and expenses) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Guarantee Trustee; provided that

         upon the occurrence of an Event of Default, of its obligation to
         exercise the rights and powers vested in it by this Guarantee Agreement

         conduct of his or her own affairs.

             (vi)   The Guarantee Trustee shall not be bound to make any

jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

severally, agree to pay to the Guarantee Trustee from time to time reasonable
compensation for all services rendered by it hereunder (which compensation shall

direction if the Guarantee Trustee shall determine that the action so directed
would be unjustly prejudicial to the Holders not taking part in such direction

and, by execution and delivery of this Guarantee Agreement, MRM hereby

Corporation, 111 8th Avenue, New York, NY 10011, Telephone: 212-590-9100, as its

Street, Hamilton, HM 12 Bermuda, Attention: James C. Kelly, Telephone:
441-295-5688, Telecopier: 441-292-1867) brought against it with respect to any
such proceeding in any such court in The City of New York, such service being
hereby acknowledged by MRM to be effective and binding service on it in every
respect whether or not MRM shall then be doing or shall have at any time done

the obligations of MRM hereunder remain outstanding, or until the appointment of
a successor by MRM, as the case may be, and such successor's acceptance of such
appointment. Upon such acceptance, MRM shall notify the Guarantee Trustee of the
name and address of such successor. MRM further agrees for the benefit of the
Guarantee Trustee and the Holders from time to time of the Preferred Securities
to take any and all action, including the execution and filing of any and all
such documents and instruments, as may be necessary to continue such designation
and appointment of said agent in full force and effect so long as any of the

not be obligated and shall have no responsibility with respect to any failure by
MRM to take any such action. Nothing herein shall affect the right to serve
process in any other manner permitted by any law or limit the right of the

court it is necessary to convert the sum due in Dollars into a currency in which
a judgment

                                       22
<PAGE>

will be rendered (the "Judgment Currency"), the rate of exchange used shall be
the rate at which in accordance with normal banking procedures the Guarantee
Trustee could purchase in The City of New York the requisite amount of Dollars
with the Judgment Currency on the Business Day preceding the day on which a
final unappealable judgment is given and (b) its obligations under this
Guarantee Agreement to make payments in Dollars (i) shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with clause (a)), in any currency other than the
Dollars, except to the extent that such tender or recovery shall result in the
actual receipt, by the payee, of the full amount of the Dollars expressed to be
payable in respect of such payments, (ii) shall be enforceable as an alternative
or additional cause of action for the purpose of recovering in Dollars the
amount, if any, by which such actual receipt shall fall short of the full amount
of Dollars so expressed to be payable and (iii) shall not be affected by
judgment being obtained for any other sum due under this Agreement.

         Section 8.10. Net Payments. All payments hereunder by MRM ("Guarantee
Payments") shall be made by MRM without withholding or deduction at source for,
or on account of, any present or future taxes, fees, duties, assessments or
governmental charges of whatever nature imposed or levied by or on behalf of
Bermuda (a "taxing jurisdiction") or any political subdivision or taxing
authority thereof or therein, unless such taxes, fees, duties, assessments or
governmental charges are required to be withheld or deducted by (i) the laws (or
any regulations or ruling promulgated thereunder) of a taxing jurisdiction or
any political subdivision or taxing authority thereof or therein or (ii) an
official position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If a
withholding or deduction at source is required, MRM shall, subject to certain
limitations and exceptions set forth below, pay to the Holder of any Preferred
Security such Additional Amounts (as defined below) as may be necessary so that
every net Guarantee Payment, after such withholding or deduction, shall not be
less than the amount due and payable pursuant to this Guarantee Agreement;
provided, however, that MRM shall not be required to make payment of such
Additional Amounts for or on account of:

                                (1) any tax, fee, duty, assessment or
                           governmental change of whatever nature which would
                           not have been imposed but for the fact that such
                           Holder: (A) was a resident, domiciliary or national
                           of, or engaged in business or maintained a permanent
                           establishment or was physically present in, the
                           taxing jurisdiction or any political subdivision
                           thereof or otherwise had some connection with

                                       23
<PAGE>

                           the taxing jurisdiction other than by reason of the
                           mere ownership of such Preferred Security or receipt
                           of a Guarantee Payment; (B) presented such Preferred
                           Security for payment in the taxing jurisdiction or
                           any political subdivision thereof, unless such
                           Preferred Security could not have been presented for
                           payment elsewhere; or (C) presented such Preferred
                           Security more than 30 days after the date on which
                           the payment in respect of such Preferred Security
                           first became due and payable or provided for,
                           whichever is later, except to the extent that the
                           Holder would have been entitled to such Additional
                           Amounts if it had presented such Preferred Security
                           for payment on any day within such period of 30 days;

                                (2) any estate, inheritance, gift, sale,
                           transfer, personal property or similar tax,
                           assessment or other governmental charge;

                                (3) any tax, assessment or other governmental
                           charge that is imposed or withheld by reason of the
                           failure by the Holder or the beneficial owner of such
                           Preferred Security to comply with any reasonable
                           request by MRM addressed to the Holder within 90 days
                           of such request (A) to provide information concerning
                           the nationality, residence or identity of the Holder
                           or such beneficial owner or (B) to make any
                           declaration or other similar claim or satisfy any
                           information or reporting requirement, which, in the
                           case of (A) or (B), is required or imposed by
                           statute, treaty, regulation or administrative
                           practice of the taxing jurisdiction or any political
                           subdivision thereof as a precondition to exemption
                           from all or part of such tax, assessment or other
                           governmental charge; or

                                (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any Guarantee Payment to
any Holder who is a fiduciary or partnership or other than the sole beneficial
owner of such Preferred Security to the extent such payment would be required by
the laws of the taxing jurisdiction (or any political subdivision or taxing
authority thereof or therein) to be included in the income for tax purposes of a
beneficiary or partner or settlor with respect to such fiduciary or a member of
such partnership or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the holder of the Preferred Security.

         If any withholding for or on account of any tax, fee, duty, assessment
or other governmental charge described in this Section 8.10 shall be required in
connection with a Guarantee Payment, MRM shall specify, in a certificate to the
Guarantee Trustee, by the jurisdiction in which the Holders of Preferred
Securities are resident for tax purposes the amount, if any, required to be
withheld on such payments to such Holders, and MRM agrees to pay to the
Guarantee Trustee the additional amounts required by this Section 8.10. MRM
covenants to indemnify the Guarantee Trustee for, and to hold it harmless
against, any loss, liability or expense reasonably incurred without negligence
or bad faith on its part arising out of or in connection with actions taken or
omitted by it in reliance on any such certificate furnished pursuant to this
Section 8.10.

         "Additional Amounts" means any additional amounts which are required
hereby, under circumstances specified herein, to be paid by MRM in respect of
certain taxes, assessments or other governmental charges imposed on Holders and
which are owing to such Holders.
