matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Agreement, they may, but need not, be consolidated and
form one instrument.

Section 1.4 Acts of Holders; Record Dates.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Purchase Contract Agent and, where it is hereby expressly required, to
the Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and (subject to Section 7.1) conclusive in favor of
the Purchase Contract Agent and the Company, if made in the manner provided in
this Section.

                                       15
<PAGE>

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any manner which the Purchase Contract
Agent deems sufficient.

         (c) The ownership of Units shall be proved by the Corporate Units
Register or the Treasury Units Register, as the case may be.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Certificate shall bind every future
Holder of the same Certificate and the Holder of every Certificate issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Purchase
Contract Agent or the Company in reliance thereon, whether or not notation of
such action is made upon such Certificate.

         (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Units entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Agreement to be given, made or taken by
Holders of Units. If any record date is set pursuant to this paragraph, the
Holders of the Outstanding Corporate Units and the Outstanding Treasury Units,
as the case may be, on such record date, and no other Holders, shall be entitled
to take the relevant action with respect to the Corporate Units or the Treasury
Units, as the case may be, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite
number of Outstanding Units on such record date. Nothing contained in this
paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and be of no effect), and nothing
contained in this paragraph shall be construed to render ineffective any action
taken by Holders of the requisite number of Outstanding Units on the date such
action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Purchase Contract Agent in writing and to each Holder of Units in
the manner set forth in Section 1.6.

                                       16
<PAGE>

         With respect to any record date set pursuant to this Section, the
Company may designate any date as the "Expiration Date" and from time to time
may change the Expiration Date to any earlier or later day; provided that no
such change shall be effective unless notice of the proposed new Expiration Date
is given to the Purchase Contract Agent in writing, and to each Holder of Units
in the manner set forth in Section 1.6, on or prior to the existing Expiration
Date. If an Expiration Date is not designated with respect to any record date
set pursuant to this Section, the Company shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

Section 1.5 Notices.

         Any notice or communication is duly given if in writing and delivered
in Person or mailed by first-class mail (registered or certified, return receipt
requested), telecopier (with receipt confirmed) or overnight air courier
guaranteeing next day delivery, to the others' address; provided that notice

Section 1.6 Notice to Holders; Waiver.

         Where this Agreement provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the applicable Register, not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Agreement provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Purchase Contract Agent, but such filing shall not be a condition precedent to
the validity of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Purchase
Contract Agent shall constitute a sufficient notification for every purpose
hereunder.

Section 1.7 Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

Section 1.8 Successors and Assigns.

         All covenants and agreements in this Agreement by the Company shall
bind its successors and assigns, whether so expressed or not.

Section 1.9 Severability.

         If any provision in this Agreement is invalid or unenforceable in any
jurisdiction, then, to the fullest extent permitted by law, (i) the other
provisions of this Agreement shall remain in full force and effect in such
jurisdiction and shall be liberally construed in order to carry out the
intentions of the parties hereto as nearly as may be possible and (ii) the
invalidity or unenforceability of any provision of this Agreement in any
jurisdiction shall not in any way affect the validity or enforceability of such
provision in any other jurisdiction.

Section 1.10 Benefits of Agreement.

         Nothing contained in this Agreement or in the Units, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder and, to the extent provided hereby, the Holders, any
benefits or any legal or equitable right, remedy or claim under this Agreement.
The Holders from time to time shall be beneficiaries of this Agreement and shall
be bound by all of the terms and conditions hereof and of the Units evidenced by
their Certificates by their acceptance of delivery of such Certificates.

Section 1.11 Governing Law; Jurisdiction and Venue.

         THIS AGREEMENT AND THE UNITS SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         The Company, the Purchase Contract Agent and the Holders from time to
time of the Units, acting through the Purchase Contract Agent as their
attorney-in-fact, hereby submit to the nonexclusive jurisdiction of the United
States District Court for the Southern District of New York for the purposes of
all legal proceedings arising out of or relating to this Agreement or the
transactions contemplated hereby. The Company and the Holders from time to time
of the Units, acting through the Purchase Contract Agent as their
attorney-in-fact, irrevocably waive, to the fullest extent permitted by
applicable law, any objection which they may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

Section 1.12 Legal Holidays.

         In any case where any Payment Date shall not be a Business Day, then
(notwithstanding any other provision of this Agreement, the Corporate Unit
Certificates or the Treasury Unit Certificates) payments by or owed from the
Company contemplated by this Agreement shall not be made on such date, but shall
be made on the next succeeding Business Day with the same force and effect as if
made on such Payment Date, provided that no interest shall accrue or be payable
by the Company or any Holder for the period from and after any such Payment
Date, except that, if such next succeeding Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day with the same force and effect as if made on such Payment
Date.

         In any case where any Purchase Contract Settlement Date shall not be a
Business Day, notwithstanding any other provision of this Agreement, the
Corporate Unit Certificates or the Treasury Unit Certificates, Purchase
Contracts shall not be settled on such date, but the Purchase Contracts shall be
settled on the immediately following Business Day with the same force and effect
as if performed on the Purchase Contract Settlement Date.

         This Agreement may be executed in any number of counterparts by the

delivered, shall be deemed an original, but all such counterparts shall together
constitute one and the same instrument.

         A copy of this Agreement shall be available at all reasonable times
during normal business hours at the Corporate Trust Office for inspection by any
Holder or Beneficial Owner.

         Every Global Certificate authenticated, executed on behalf of the
Holders and delivered hereunder shall bear a legend in substantially the
following form:

                  "This Certificate is a Global Certificate within the meaning
         of the Purchase Contract Agreement hereinafter referred to and is
         registered in the name of The Depository Trust Company, a New York
         corporation (the "Depositary"), or a nominee of the Depositary. This

         a person other than the Depositary or its nominee only in the limited
         circumstances described in the Purchase Contract Agreement and no
         transfer of this Certificate (other than a transfer of this Certificate
         as a whole by the Depositary to a nominee of the Depositary or by a

                  Unless this Certificate is presented by an authorized
         representative of the Depositary to Endurance Specialty Holdings Ltd.
         or its agent for registration of transfer, exchange or payment, and any
         certificate issued is registered in the name of Cede & Co. or such
         other name as is requested by an authorized representative of the
         Depositary (and any payment hereon is made to Cede & Co. or to such

         Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
         OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the registered owner
         hereof, Cede & Co., has an interest herein."

<PAGE>

         The Certificates shall be issuable only in registered form and only in
denominations of a single Corporate Unit or Treasury Unit and any integral
multiple thereof.

Section 3.2 Rights and Obligations Evidenced by the Certificates.

         Each Corporate Unit Certificate shall evidence the number of Corporate
Units specified therein, with each such Corporate Unit representing (1) the
ownership by the Holder thereof of a beneficial interest in one Debt Security
or, if substituted therefor, the Pledged Treasury Portfolio Interest, in either
case, subject to the Pledge of such Debt Security or such Pledged Treasury
Portfolio Interest, as the case may be, by such Holder pursuant to the Pledge
Agreement, and (2) the rights and obligations of the Holder thereof and the
Company under one Purchase Contract. The Purchase Contract Agent as
attorney-in-fact for, and on behalf of, the Holder of each Corporate Unit shall
pledge, pursuant to the Pledge Agreement, the Debt Security or, if substituted
therefor, the Treasury Portfolio Interest, forming a part of such Corporate
Unit, to the Collateral Agent and grant to the Collateral Agent a security
interest in the right, title and interest of such Holder in such Debt Security
or such Treasury Portfolio Interest, as the case may be, for the benefit of the
Company, to secure the obligation of the Holder under each Purchase Contract to
purchase Ordinary Shares pursuant to the Purchase Contract.

         Upon the formation of Treasury Units pursuant to Section 3.13, each
Treasury Unit Certificate shall evidence the number of Treasury Units specified
therein, with each such Treasury Unit representing (1) the ownership by the
Holder thereof of a 1/20 undivided beneficial interest in a Treasury Security
with a principal amount equal to $1,000, subject to the Pledge of such Treasury
Security by such Holder pursuant to the Pledge Agreement, and (2) the rights and
obligations of the Holder thereof and the Company under one Purchase Contract.
The Purchase Contract Agent as attorney-in-fact for, and on behalf of, the
Holder of each Treasury Unit shall pledge, pursuant to the Pledge Agreement, the
Treasury Security or Treasury Securities forming a part of such Treasury Unit,
to the Collateral Agent and grant to the Collateral Agent a security interest in
the right, title and interest of such Holder in such Treasury Security or
Treasury Securities for the benefit of the Company, to secure the obligation of
the Holder under each Purchase Contract to purchase Ordinary Shares pursuant to
this Agreement and the related Purchase Contract.

         Prior to the purchase of Ordinary Shares under each Purchase Contract,
such Purchase Contract shall not entitle the Holder of a Corporate Unit
Certificate or a Treasury Unit Certificate to any of the rights of a holder of
Ordinary Shares, including, without limitation, the right to vote or receive any
dividends or other payments or to consent or to receive notice as a shareholder
in respect of the meetings of shareholders or for the election of directors of
the Company or for any other matter, or any other rights whatsoever as a
shareholder of the Company.

Section 3.3 Execution, Authentication, Delivery and Dating.

         Subject to the provisions of Sections 3.1, 3.13 and 3.14 hereof, upon
the execution and delivery of this Agreement, and at any time and from time to
time thereafter, the Company may deliver Certificates executed by the Company to
the Purchase Contract Agent for authentication, execution on behalf of the
Holders and delivery, together with its Issuer Order for authentication of such
Certificates, and the Purchase Contract Agent in accordance with such Issuer
Order shall authenticate, execute on behalf of the Holders and deliver such
Certificates.

         The Certificates shall be executed on behalf of the Company by its
Chairman of the Board, President, one of its Vice Presidents, Corporate
Secretary or Treasurer. The signature of any of these officers on the
Certificates may be manual or facsimile.

         Certificates bearing the manual or facsimile signatures of an
individual who was at any time the proper officer of the Company shall bind the
Company, notwithstanding that such individual has ceased to hold such office
prior to the authentication and delivery of such Certificates or did not hold
such office at the date of such Certificates.

         No Purchase Contract evidenced by a Certificate shall be valid until
such Certificate has been executed on behalf of the Holder by the manual
signature of an authorized officer of the Purchase Contract Agent, as such
Holder's attorney-in-fact. Such signature by an authorized officer of the
Purchase Contract Agent shall be conclusive evidence that the Holder of such
Certificate has entered into the Purchase Contract or Purchase Contracts
evidenced by such Certificate.

         Each Certificate shall be dated the date of its authentication.

         No Certificate shall be entitled to any benefit under this Agreement or
be valid or obligatory for any purpose unless there appears on such Certificate
a certificate of authentication substantially in the form provided for herein
executed by an authorized officer of the Purchase Contract Agent by manual
signature, and such certificate upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

Section 3.4 Temporary Certificates.

         Pending the preparation of definitive Certificates, the Company shall
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu
of such definitive Certificates, temporary Certificates which are in
substantially the form set forth in Exhibit A or Exhibit B hereto, as the case
may be, with such letters, numbers or other marks of identification or
designation and such legends or endorsements printed, lithographed or engraved
thereon as may be required by the rules of any securities exchange on which the
Corporate Units or Treasury Units are or may be listed, or as may, consistently
herewith, be determined by the officers of the Company executing such
Certificates, as evidenced by their execution of the Certificates.

                                       23
<PAGE>

         If temporary Certificates are issued, the Company will cause definitive
Certificates to be prepared without unreasonable delay. After the preparation of
definitive Certificates, the temporary Certificates shall be exchangeable for
definitive Certificates upon surrender of the temporary Certificates at the
Corporate Trust Office, at the expense of the Company and without charge to the
Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Company shall execute and deliver to the Purchase Contract
Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of
the Holder, and deliver in exchange therefor, one or more definitive
Certificates of like tenor and denominations and evidencing a like aggregate
number of Corporate Units or Treasury Units, as the case may be, as the
temporary Certificate or Certificates so surrendered. Until so exchanged, the
temporary Certificates shall in all respects evidence the same benefits and the
same obligations with respect to the Corporate Units or Treasury Units, as the
case may be, evidenced thereby as definitive Certificates.

Section 3.5 Registration; Registration of Transfer and Exchange.

         The Purchase Contract Agent shall keep at the Corporate Trust Office a
register (the "Corporate Units Register") in which, subject to such reasonable
regulations as it may prescribe, the Purchase Contract Agent shall provide for
the registration of Corporate Unit Certificates and of transfers of Corporate
Unit Certificates (the Purchase Contract Agent, in such capacity, the "Corporate
Units Registrar") and a register (the "Treasury Units Register") in which,
subject to such reasonable regulations as it may prescribe, the Purchase
Contract Agent shall provide for the registration of the Treasury Unit
Certificates and transfers of Treasury Unit Certificates (the Purchase Contract
Agent, in such capacity, the "Treasury Units Registrar").

         Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office, the Company shall execute and deliver to the Purchase
Contract Agent, and the Purchase Contract Agent shall authenticate, execute on
behalf of the designated transferee or transferees, and deliver, in the name of
the designated transferee or transferees, one or more new Certificates of any
authorized denominations, like tenor, and evidencing a like aggregate number of
Corporate Units or Treasury Units, as the case may be.

         At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Corporate Units or Treasury Units, as the case may be, upon surrender of the
Certificates to be exchanged at the Corporate Trust Office. Whenever any
Certificates are so surrendered for exchange, the Company shall execute and
deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall
authenticate, execute on behalf of the Holder, and deliver the Certificates
which the Holder making the exchange is entitled to receive.

                                       24
<PAGE>

         All Certificates issued upon any registration of transfer or exchange
of a Certificate shall evidence the ownership of the same aggregate number of
Corporate Units or Treasury Units, as the case may be, and be entitled to the
same benefits and subject to the same obligations, under this Agreement as the
Corporate Units or Treasury Units, as the case may be, evidenced by the
Certificate surrendered upon such registration of transfer or exchange.

         Every Certificate presented or surrendered for registration of transfer
or for exchange shall (if so required by the Purchase Contract Agent) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Purchase Contract Agent duly executed, by
the Holder thereof or its attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Purchase Contract Agent may
require payment from the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Certificates, other than any exchanges pursuant to
Sections 3.4, 3.6 and 8.5 not involving any transfer.

         Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall not be obligated to authenticate, execute on behalf of the Holder
and deliver any Certificate in exchange for any other Certificate presented or
surrendered for registration of transfer or for exchange on or after the
Business Day immediately preceding the earlier of the Purchase Contract
Settlement Date or the Termination Date. In lieu of delivery of a new
Certificate, upon satisfaction of the applicable conditions specified above in
this Section and receipt of appropriate registration or transfer instructions
from such Holder, the Purchase Contract Agent shall:

                  (1) if the Purchase Contract Settlement Date has occurred,
         deliver the Ordinary Shares issuable in respect of the Purchase
         Contracts forming a part of the Units evidenced by such other
         Certificate; or

                  (2) if a Termination Event shall have occurred prior to the
         Purchase Contract Settlement Date, transfer the Debt Securities, the
         Treasury Portfolio or the Treasury Securities, as the case may be,
         evidenced thereby,

in each case subject to the applicable conditions and in accordance with the
applicable provisions of Article Five hereof.

Section 3.6 Book-Entry Interests.

         The Certificates, on original issuance, will be issued in the form of
one or more fully registered Global Certificates, to be delivered to the
Depositary or its custodian by, or on behalf of, the Company. Such Global
Certificate shall initially be registered on the books and records of the
Company in the name of Cede & Co., the nominee of the Depositary, and no
Beneficial Owner will receive a definitive Certificate representing such
Beneficial Owner's interest in such Global Certificate, except as provided in
Section 3.9. The Purchase Contract Agent shall enter into an agreement with the
Depositary if so requested by the Company. Unless and until definitive, fully
registered Certificates have been issued to Beneficial Owners pursuant to
Section 3.9:

                                       25
<PAGE>

                  (1) the provisions of this Section 3.6 shall be in full force
         and effect;

                  (2) the Company shall be entitled to deal with the Depositary
         for all purposes of this Agreement (including making Purchase Contract
         Adjustment Payments and receiving approvals, votes or consents
         hereunder) as the Holder of the Units and the sole holder of the Global
         Certificates and shall have no obligation to the Beneficial Owners;

                  (3) to the extent that the provisions of this Section 3.6
         conflict with any other provisions of this Agreement, the provisions of
         this Section 3.6 shall control; and

                  (4) the rights of the Beneficial Owners shall be exercised
         only through the Depositary and shall be limited to those established
         by law and agreements between such Beneficial Owners and the Depositary
         and/or the Depositary Participants.

Section 3.7 Notices to Holders.

         Whenever a notice or other communication to the Holders is required to
be given under this Agreement, the Company or the Company's agent shall give
such notices and communications to the Holders and, with respect to any Units
registered in the name of a Depositary or the nominee of a Depositary, the
Company or the Company's agent shall, except as set forth herein, have no
obligations to the Beneficial Owners.

Section 3.8 Appointment of Successor Depositary.

         If any Depositary elects to discontinue its services as securities
depositary with respect to the Units or ceases to be eligible as a "depositary"
under the Exchange Act, the Company may, in its sole discretion, appoint a
successor Depositary with respect to the Units.

Section 3.9 Definitive Certificates.

         If (a) the Depositary is at any time unwilling, unable or ineligible to
continue as a "clearing agency" registered under the Exchange Act and a
successor Depositary is not appointed by the Company pursuant to Section 3.8
within 90 days of the date the Company and the Purchase Contract Agent is so
informed in writing thereof, (b) the Company executes and delivers to the
Purchase Contract Agent a Company Order (as defined in the Indenture) to the
effect that the Global Certificates shall be exchangeable for Definitive
Certificates or (c) a default by the Company in respect of its obligations under
one or more Purchase Contracts has occurred and is continuing, then upon
surrender of the Global Certificates representing the Units by the Depositary,
accompanied by registration instructions, the Company shall cause definitive
Certificates to be delivered to Beneficial Owners in accordance with the
instructions of the Depositary. The Company and the Purchase Contract Agent
shall not be liable for any delay in delivery of such instructions and may
conclusively rely on and shall be protected in relying on, such instructions.

                                       26

Section 3.10 Mutilated, Destroyed, Lost and Stolen Certificates.

         If any mutilated Certificate is surrendered to the Purchase Contract
Agent, the Company shall execute and deliver to the Purchase Contract Agent, and
the Purchase Contract Agent shall authenticate, execute on behalf of the Holder,
and deliver in exchange therefor, a new Certificate, evidencing the same number
of Corporate Units or Treasury Units, as the case may be, and bearing a
Certificate number not contemporaneously outstanding.

         If there shall be delivered to the Company and the Purchase Contract
Agent (i) evidence to their satisfaction of the destruction, loss or theft of
any Certificate, and (ii) such security or indemnity as may be required by them
to hold each of them and any agent of any of them harmless, then, in the absence
of notice to the Company or to a Responsible Officer of the Purchase Contract
Agent that such Certificate has been acquired by a bona fide purchaser, the
Company shall execute and deliver to the Purchase Contract Agent, and the
Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and
deliver to the Holder, in lieu of any such destroyed, lost or stolen
Certificate, a new Certificate, evidencing the same number of Corporate Units or
Treasury Units, as the case may be, and bearing a Certificate number not
contemporaneously outstanding.

         Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall not be obligated to authenticate, execute on behalf of the Holder,
and deliver to the Holder, a Certificate on or after the Business Day
immediately preceding the earlier of the Purchase Contract Settlement Date or
the Termination Date. In lieu of delivery of a new Certificate, upon
satisfaction of the applicable conditions specified above in this Section and
receipt of appropriate registration or transfer instructions from such Holder,
the Purchase Contract Agent shall:

                  (1) if the Purchase Contract Settlement Date has occurred,
         deliver the Ordinary Shares issuable in respect of the Purchase
         Contracts forming a part of the Units evidenced by such Certificate; or

                  (2) if a Termination Event shall have occurred prior to the
         Purchase Contract Settlement Date, transfer the Debt Securities, the
         Treasury Portfolio or the Treasury Securities, as the case may be,
         evidenced thereby,

                                       27
<PAGE>

in each case subject to the applicable conditions and in accordance with the
applicable provisions of Article Five hereof.

         Upon the issuance of any new Certificate under this Section, the
Company and the Purchase Contract Agent may require the payment by the Holder of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Purchase Contract Agent) connected therewith.

         Every new Certificate issued pursuant to this Section in lieu of any
destroyed, lost or stolen Certificate shall constitute an original additional
contractual obligation of the Company and of the Holder in respect of the Units
evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and
the Units evidenced thereby) shall be at any time enforceable by anyone, and
shall be entitled to all the benefits and be subject to all the obligations of
this Agreement equally and proportionately with any and all other Certificates
delivered hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Certificates.

Section 3.11 Persons Deemed Owners.

         Prior to due presentment of a Certificate for registration of transfer,
the Company and the Purchase Contract Agent, and any agent of the Company or the
Purchase Contract Agent, may treat the Person in whose name such Certificate is
registered as the owner of the Corporate Units or Treasury Units evidenced
thereby, for the purpose of receiving interest payments on the Debt Securities,
receiving Purchase Contract Adjustment Payments, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any interest
payments on the Debt Securities or the Purchase Contract Adjustment Payments
payable in respect of the Purchase Contracts constituting a part of the
Corporate Units or Treasury Units evidenced thereby shall be overdue and
notwithstanding any notice to the contrary, and neither the Company nor the
Purchase Contract Agent, nor any agent of the Company or the Purchase Contract
Agent, shall be affected by notice to the contrary.

         Notwithstanding the foregoing, with respect to any Global Certificate,
nothing contained herein shall prevent the Company, the Purchase Contract Agent
or any agent of the Company or the Purchase Contract Agent, from giving effect
to any written certification, proxy or other authorization furnished by any
Depositary (or its nominee), as a Holder, with respect to such Global
Certificate or impair, as between such Depositary and owners of beneficial
interests in such Global Certificate, the operation of customary practices
governing the exercise of rights of such Depositary (or its nominee) as Holder
of such Global Certificate.

                                       28

Section 3.12 Cancellation.

         All Certificates surrendered for delivery of Ordinary Shares on or
after the Purchase Contract Settlement Date, upon the transfer of Debt
Securities, the Treasury Portfolio or Treasury Securities, as the case may be,
after the occurrence of a Termination Event or pursuant to an Early Settlement,
or a Collateral Substitution or the recreation of Corporate Units or upon the
registration of a transfer or exchange of a Unit, shall, if surrendered to any
Person other than the Purchase Contract Agent, be delivered to the Purchase
Contract Agent and, if not already cancelled, shall be promptly cancelled by it.
The Company may at any time deliver to the Purchase Contract Agent for
cancellation any Certificates previously authenticated, executed and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the
Purchase Contract Agent. No Certificates shall be authenticated, executed on
behalf of the Holder and delivered in lieu of or in exchange for any
Certificates cancelled as provided in this Section, except as expressly
permitted by this Agreement. All cancelled Certificates held by the Purchase
Contract Agent shall be disposed of by the Purchase Contract Agent in accordance
with its customary procedures.

         If the Company or any Affiliate of the Company shall acquire any
Certificate, such acquisition shall not operate as a cancellation of such
Certificate unless and until such Certificate is delivered to the Purchase
Contract Agent cancelled or for cancellation.

Section 3.13 Creation of Treasury Units by Substitution of Treasury Securities.

         A Holder may separate the Debt Securities from the related Purchase
Contracts in respect of such Holder's Corporate Units by substituting for such
Debt Securities Treasury Securities or security entitlements thereto, pursuant
to the Pledge Agreement, in an aggregate principal amount equal to the aggregate
principal amount of such Debt Securities, at any time from and after the date of
this Agreement until 5:00 p.m. (New York City time) on the Election Date by:

                  (1) providing notice to the Purchase Contract Agent,
         substantially in the form of Exhibit C hereto, of such Holder's
         intention to create Treasury Units;

                  (2) for each group of 20 Corporate Units from which such
         Holder wishes to create Treasury Units, transferring a Treasury
         Security to the Securities Intermediary which shall then (y) deposit
         the Treasury Security with the Collateral Agent in the Collateral
         Account under the Pledge Agreement and instruct the Collateral Agent to
         hold such Treasury Security as Collateral under the Pledge Agreement
         and (z) instruct the Collateral Agent to release to the Purchase
         Contract Agent, on behalf of such Holder, $1,000 principal amount of
         Debt Securities formerly subject to the Pledge;

                                       29
<PAGE>

                  (3) transferring the related Corporate Units to the Purchase
         Contract Agent accompanied by a notice to the Purchase Contract Agent,
         substantially in the form of Exhibit D hereto, stating that the Holder
         has transferred the relevant amount of Treasury Securities to the
         Securities Intermediary and requesting that the Purchase Contract Agent
         instruct the Collateral Agent to release the Debt Securities relating
         to such Corporate Units, whereupon the Purchase Contract Agent shall
         promptly give such instruction to the Collateral Agent, substantially
         in the form of Exhibit A to the Pledge Agreement; and

                  (4) paying to the Collateral Agent any fees or expenses
         incurred in connection with the Collateral Substitution;

provided that, Holders may make Collateral Substitutions only in integral
multiples of 20 Corporate Units. Under no circumstances may a Holder of
Corporate Units create Treasury Units after the Election Date.

         The Holders' right to create Treasury Units as set forth in this
Section and the limit of the preceding sentence shall in no way limit the
ability of the Purchase Contract Agent, the Collateral Agent, the Securities
Intermediary or the Remarketing Agent to substitute the Treasury Portfolio for
the Debt Securities then comprising a part of the Corporate Units upon a
Successful Remarketing (other than the Debt Securities of Holders of Corporate
Units that have elected not to participate in the Remarketing).

         Upon receipt of the Treasury Securities described in clause (2) above
and the instruction described in clause (1) above, in accordance with the terms
of the Pledge Agreement, the Collateral Agent shall, under the Pledge Agreement,
cause the Securities Intermediary to effect the release of such Debt Securities
from the Pledge to the Purchase Contract Agent, free and clear of the Company's
security interest therein, and the transfer of such Debt Securities to the
Purchase Contract Agent on behalf of the Holder thereof. Upon receipt thereof,
the Purchase Contract Agent shall promptly:

                           (i) cancel the related Corporate Units;

                           (ii) transfer the applicable aggregate principal
                  amount of Debt Securities to the Holder; and

                           (iii) authenticate, execute on behalf of such Holder
                  and deliver a Treasury Unit Certificate executed by the
                  Company in accordance with Section 3.3 evidencing the same
                  number of Purchase Contracts as were evidenced by the
                  cancelled Corporate Units.

                                       30
<PAGE>

         Holders who elect to separate the Debt Securities from the related
Purchase Contracts and to substitute Treasury Securities for such Debt
Securities shall be responsible for any fees or expenses payable to the
Collateral Agent for its services as Collateral Agent in respect of the
substitution, and the Company shall not be responsible for any such fees or
expenses.

         In the event a Holder making a Collateral Substitution pursuant to this
Section 3.13 fails to effect a book-entry transfer of the Corporate Units or
fails to deliver Corporate Unit Certificates to the Purchase Contract Agent
after depositing Treasury Securities with the Collateral Agent, then the Debt
Securities or Treasury Portfolio Interest, as the case may be, constituting a
part of such Corporate Units, and any interest payments on such Debt Securities
or the Treasury Portfolio Interest, as the case may be, shall be held in the
name of the Purchase Contract Agent or its nominee in trust for the benefit of
such Holder, until such Corporate Units are so transferred or the Corporate Unit
Certificates are so delivered, as the case may be, or, with respect to the
Corporate Unit Certificates, such Holder provides evidence satisfactory to the
Company and the Purchase Contract Agent that such Corporate Unit Certificates
have been destroyed, lost or stolen, together with any indemnity that may be
required by the Purchase Contract Agent and the Company.

                  Except as described in this Sections 3.13 and 5.3, for so long
as the Purchase Contract relating to a Corporate Unit remains in effect, such
Corporate Unit shall not be separable into its constituent parts, and the rights
and obligations of the Holder in respect of the Debt Security or the Treasury
Portfolio Interest, as the case may be, and the Purchase Contract comprising
such Corporate Unit may be acquired, and may be transferred and exchanged, only
as a Corporate Unit.

Section 3.14 Recreation of Corporate Units.

         A Holder of Treasury Units may recreate Corporate Units at any time
until 5:00 p.m. (New York City time) on the Election Date by:

                  (1) providing notice to the Purchase Contract Agent,
         substantially in the form of Exhibit C hereto, of such Holder's
         intention to create Corporate Units;

                  (2) for each Treasury Unit such Holder wishes to substitute,
         transferring 20 Debt Securities to the Securities Intermediary which
         shall then (y) deposit such Debt Securities in the Collateral Account
         under the Pledge Agreement and instruct the Collateral Agent to hold
         such Debt Securities as Collateral and (z) instruct the Collateral
         Agent to release to such Holder the Treasury Security formerly subject
         to the Pledge;

                  (3) transferring the related Treasury Units to the Purchase
         Contract Agent accompanied by a notice to the Purchase Contract Agent,
         substantially in the form of Exhibit D hereto, (i) stating that the
         Holder has transferred the relevant amount of Debt Securities to the
         Securities Intermediary and (ii) requesting that the Purchase Contract
         Agent instruct the Collateral Agent to release the Treasury Securities
         relating to such Treasury Units, whereupon the Purchase Contract Agent
         shall promptly give such instruction to the Collateral Agent,
         substantially in the form of Exhibit C to the Pledge Agreement; and

                                       31
<PAGE>

                  (4) paying to the Collateral Agent any fees or expenses
         incurred in connection with the recreation of Corporate Units;

provided that, Holders of Treasury Units may recreate Corporate Units in
integral multiples of 20 Treasury Units for 20 Corporate Units. Under no
circumstance may a Holder of Treasury Units recreate Corporate Units after the
Election Date.

         Upon receipt of the Debt Securities described in clause (1) above and
the instruction described in clause (2) above, in accordance with the terms of
the Pledge Agreement, the Collateral Agent shall cause the Securities
Intermediary to effect the release of such Treasury Securities from the Pledge,
free and clear of the Company's security interest therein, and the transfer of
such Treasury Securities to the Holder thereof. Upon receipt thereof, the
Purchase Contract Agent shall promptly:

                           (i) cancel the related Treasury Units; and

                           (ii) authenticate, execute on behalf of such Holder
                  and deliver a Corporate Unit Certificate executed by the
                  Company in accordance with Section 3.3 evidencing the same
                  number of Purchase Contracts as were evidenced by the
                  cancelled Treasury Units.

         Holders who elect to recreate Corporate Units shall be responsible for
any fees or expenses payable to the Collateral Agent for its services as
Collateral Agent in respect of the substitution, and the Company shall not be
responsible for any such fees or expenses.

         Except as provided in this Section 3.14, for so long as the Purchase
Contract relating to a Treasury Unit remains in effect, such Treasury Unit shall
not be separable into its constituent parts and the rights and obligations of
the Holder of such Treasury Unit in respect of the 1/20 of a Treasury Security
and the Purchase Contract comprising such Treasury Unit may be acquired, and may
be transferred and exchanged, only as a Treasury Unit.

Section 3.15 Transfer of Collateral upon Occurrence of Termination Event.

         Upon the occurrence of a Termination Event and the transfer to the
Purchase Contract Agent of Debt Securities, Treasury Portfolio or Treasury
Securities, as the case may be, relating to the Corporate Units and the Treasury
Units, as the case may be, pursuant to the terms of the Pledge Agreement, the
Purchase Contract Agent shall request transfer instructions with respect to such
Debt Securities, Treasury Portfolio Interest or Treasury Securities, as the case
may be, from each Holder by written request, substantially in the form of
Exhibit E hereto, mailed to such Holder at its address as it appears in the
Corporate Units Register or the Treasury Units Register, as the case may be.

                                       32
<PAGE>

         Upon book-entry transfer of the Corporate Units or Treasury Units or
delivery of a Corporate Unit Certificate or Treasury Unit Certificate to the
Purchase Contract Agent with such transfer instructions, the Purchase Contract
Agent shall transfer such Debt Securities, Treasury Portfolio Interest or
Treasury Securities, as the case may be, relating to such Corporate Units or
Treasury Units, as the case may be, to such Holder by book-entry transfer, or
other appropriate procedures, in accordance with such instructions. In the event
a Holder of Corporate Units or Treasury Units fails to effect such transfer or
delivery, such Debt Securities, Treasury Portfolio Interest or Treasury
Securities, as the case may be, relating to such Corporate Units or Treasury
Units, as the case may be, and any interest thereon, shall be held in the name
of the Purchase Contract Agent or its nominee in trust for the benefit of such
Holder, until the earlier of:

                  (1) such Corporate Units or Treasury Units are transferred or
         the Corporate Unit Certificate or Treasury Unit Certificate is
         surrendered or such Holder provides satisfactory evidence that such
         Corporate Unit Certificate or Treasury Unit Certificate has been
         destroyed, lost or stolen, together with any indemnity that may be
         required by the Purchase Contract Agent and the Company; and

                  (2) the expiration of the time period specified in the
         abandoned property laws of the relevant State.

Section 3.16 No Consent to Assumption.

         Each Holder of a Unit, by acceptance thereof, shall be deemed expressly
to have withheld any consent to the assumption under Section 365 of the
Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its
trustee, receiver, liquidator or a person or entity performing similar functions
in the event that the Company becomes the debtor under the Bankruptcy Code or
subject to other similar state or federal law providing for reorganization or
liquidation.

                               The Debt Securities

Section 4.1 Interest Payments; Rights to Interest Preserved.

         Each Corporate Unit issued hereunder shall consist of the beneficial
ownership by the Holder of one Debt Security issued pursuant to the Indenture
or, if the Corporate Unit shall have been remarketed by the Remarketing Agent
pursuant to the Remarketing Agreement, the Treasury Portfolio Interest, in each
case, subject to the Pledge thereof by such Holder under the Pledge Agreement.

                                       33

         An interest payment on any Debt Security which is paid on any Payment
Date or the portion of the proceeds of a Treasury Portfolio Interest equal to
the interest payable on a Debt Security on the Purchase Contract Settlement Date
(such portion the "Treasury Portfolio Return"), as the case may be, subject to
receipt thereof by the Purchase Contract Agent from the Collateral Agent as
provided by the terms of the Pledge Agreement, shall promptly be paid to the
Person in whose name the Corporate Unit Certificate (or one or more Predecessor
Corporate Unit Certificates) of which such Debt Security or the Treasury
Portfolio Interest, as the case may be, is a part is registered at the close of
business on the Record Date for such Payment Date or Purchase Contract
Settlement Date, as applicable.

         Each Corporate Unit Certificate evidencing, in part, the Debt Security
or the Treasury Portfolio Interest delivered under this Agreement upon
registration of transfer of or in exchange for or in lieu of any other Corporate
Unit Certificate shall carry the right to accrued and unpaid interest, and the
right to accrue interest (and accreted and accreting principal in the case of
non-interest bearing components of the Treasury Portfolio Interest), which
rights were carried by the Debt Security or the Treasury Portfolio Interest, as
the case may be, relating to such other Corporate Unit Certificate.

         In the case of any Corporate Units with respect to which (1) Cash
Settlement of the related Purchase Contract is effected on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, (2) Early
Settlement of the related Purchase Contract is effected on an Early Settlement
Date, (3) Merger Early Settlement of the related Purchase Contract is effected
on a Merger Early Settlement Date or (4) a Collateral Substitution is effected,
in each case, on a date that is after any Record Date and on or prior to the
next succeeding Payment Date, the interest payment on the Debt Security or the
Treasury Portfolio Return, as the case may be, relating to such Corporate Units
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Cash Settlement, Early Settlement, Merger Early Settlement
or Collateral Substitution, as the case may be, and such payment shall, subject
to receipt thereof by the Purchase Contract Agent, be payable to the Person in
whose name the Corporate Unit Certificate (or one or more Predecessor Corporate
Unit Certificates) was registered at the close of business on the corresponding
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Corporate Units with respect to which Cash
Settlement, Early Settlement or Merger Early Settlement of the related Purchase
Contract is effected on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date, on an Early Settlement Date or on a Merger
Early Settlement Date, respectively, or with respect to which a Collateral
Substitution has been effected, interest payments on the related Debt Securities
or the Treasury Portfolio Return, as the case may be, that would otherwise be
payable after the fifth Business Day preceding the Purchase Contract Settlement
Date, after the Early Settlement Date, after the Merger Early Settlement Date,
or after the Collateral Substitution, respectively, shall not be payable
hereunder to the Holder of such Corporate Units; provided, however, that to the
extent that such Holder continues to hold the Separated Debt Security that
formerly comprised a part of such Holder's Corporate Units, such Holder shall be
entitled to receive the interest payments on such Separated Debt Security, as
provided in the Indenture.

Section 4.2 Interest Rate Reset.

         The applicable interest rate borne by the Debt Securities, whether or
not part of Corporate Units, shall be reset to the Reset Rate, pursuant to the
Indenture, and will be effective with respect to all Debt Securities, whether or
not then constituting a component of Corporate Units, as of the Remarketing
Settlement Date, in the case of a Successful Remarketing, or, as of the Purchase
Contract Settlement Date, in the event of a Failed Remarketing or in the event
there is no Remarketing pursuant to clause (c) of the definition of Reset Rate
in the Indenture Officers' Certificate.

Section 4.3 Notice and Voting.

         The Purchase Contract Agent is entitled to exercise the voting and any
other consensual rights pertaining to the Pledged Debt Securities, but only to
the extent instructed in writing by the Holders as described below. Upon receipt
of notice of any meeting at which holders of Debt Securities are entitled to
vote or upon any solicitation of consents, waivers or proxies of holders of Debt
Securities, the Purchase Contract Agent shall, as soon as practicable
thereafter, mail to the Holders of Corporate Units a notice:

                  (1) containing such information as is contained in the notice
         or solicitation;

                  (2) stating that each Holder on the record date set by the
         Purchase Contract Agent therefor (which, to the extent possible, shall
         be the same date as the record date for determining the holders of Debt
         Securities entitled to vote) shall be entitled to instruct the Purchase
         Contract Agent as to the exercise of the voting rights pertaining to
         such Debt Securities relating to their Corporate Units; and

                  (3) stating the manner in which such instructions may be
         given.

         Upon the written request of the Holders of Corporate Units on such
record date received by the Purchase Contract Agent at least six calendar days
prior to such meeting or by the expiration date of any such solicitation, the
Purchase Contract Agent shall endeavor insofar as practicable to vote or cause
to be voted, in accordance with the instructions set forth in such requests, the
maximum principal amount of Debt Securities as to which any particular voting
instructions are received. In the absence of specific instructions from the

                     The Purchase Contracts; The Remarketing

Section 5.1 Purchase of Ordinary Shares.

         Each Purchase Contract shall, unless a Termination Event has occurred
as set forth in Section 5.7, an Early Settlement has occurred in accordance with
Section 5.9 or a Merger Early Settlement has occurred in accordance with Section
5.10, obligate the Holder of the related Units to purchase, and the Company to
sell, on the Purchase Contract Settlement Date at a price equal to the Stated
Amount (the "Purchase Price"), a number of newly issued Ordinary Shares equal to
the Settlement Rate then in effect. The "Settlement Rate" is equal to:

                  (1) if the Applicable Closing Price per share is equal to or
         greater than $____ (the "Threshold Appreciation Price"), _____ Ordinary
         Shares per Purchase Contract;

                  (2) if the Applicable Closing Price per share is less than the
         Threshold Appreciation Price, but greater than $____ (the "Reference
         Price"), the number of Ordinary Shares determined by dividing the
         Stated Amount by the Applicable Closing Price; and

                  (3) if the Applicable Closing Price per share is less than or
         equal to the Reference Price, _____ Ordinary Shares per Purchase
         Contract,

in each case subject to adjustment as provided in Section 5.5 (and in each case
rounded upward or downward to the nearest 1/10,000th of a share).

         Promptly after the calculation of the Settlement Rate and the
Applicable Closing Price, the Company shall give the Purchase Contract Agent
notice thereof. All calculations and determinations of the Settlement Rate and
the Applicable Closing Price shall be made by the Company or its agent based on
their good faith calculations, and the Purchase Contract Agent shall have no
responsibility with respect thereto.

         As provided in Section 5.12, no fractional Ordinary Shares will be
issued upon settlement of Purchase Contracts.

         The "Applicable Closing Price" means the average of the Closing Prices
per share of Ordinary Shares on each of the 20 consecutive Trading Days ending
on the third Trading Day immediately preceding the Purchase Contract Settlement
Date, or in the case of the exercise of a Merger Early Settlement right, the
Cash Merger Date.

         The "Closing Price" per share of the Ordinary Shares on any date of
determination means:

                                       36
<PAGE>

                  (1) the closing sale price (or, if no closing price is
         reported, the last reported sale price) per share of the Ordinary
         Shares on the New York Stock Exchange, Inc. on such date;

                  (2) if the Ordinary Shares are not listed for trading on the
         New York Stock Exchange, Inc. on any such date, the closing sale price
         per share as reported in the composite transactions for the principal
         United States securities exchange on which the Ordinary Shares are so
         listed;

                  (3) if the Ordinary Shares are not so listed on a United
         States national or regional securities exchange, the closing sale price
         per share as reported by The Nasdaq Stock Market;

                  (4) if the Ordinary Shares are not so reported, the last
         quoted bid price per share for the Ordinary Shares in the
         over-the-counter market as reported by the National Quotation Bureau or
         similar organization; or

                  (5) if such bid price is not available, the average of the
         mid-point of the last bid and ask prices per share of the Ordinary
         Shares on such date from at least three nationally recognized
         independent investment banking firms retained for this purpose by the
         Company.

         A "Trading Day" means a day on which the Ordinary Shares (1) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (2) has
traded at least once on the national or regional securities exchange or
association or the over-the-counter market that is the primary market for the
trading of the Ordinary Shares.

         Each Holder of a Corporate Unit or a Treasury Unit, by its acceptance
thereof:

                  (1) irrevocably authorizes the Purchase Contract Agent to
         enter into and perform the related Purchase Contract on its behalf as
         its attorney-in-fact (including the execution of Certificates on behalf
         of such Holder as such Holder's attorney-in-fact);

                  (2) agrees to be bound by the terms and provisions thereof;

                  (3) covenants and agrees to perform its obligations under such
         Purchase Contracts;

                  (4) consents to the provisions hereof;

<PAGE>

                  (5) irrevocably authorizes the Purchase Contract Agent to
         enter into and perform this Agreement and the Pledge Agreement on its
         behalf as its attorney-in-fact; and

                  (6) consents to and agrees to be bound by the Pledge of the
         Debt Securities or the Treasury Securities pursuant to the Pledge
         Agreement; and

                  (7) agrees to treat itself as the owner of the related Debt
         Securities, Treasury Portfolio Interest or Treasury securities, as the
         case may be, in each case for U.S. Federal, state and local income and
         franchise tax purposes;

provided that, upon a Termination Event, the rights of the Holder of such Unit
under the Purchase Contract may be enforced without regard to any other rights
or obligations. Each Holder of a Corporate Unit or a Treasury Unit, by its
acceptance thereof, further covenants and agrees, that to the extent and in the
manner provided in Section 5.3 and the Pledge Agreement, but subject to the
terms thereof, proceeds from the Remarketing of the Debt Securities (less the
Remarketing Fee payable to the Remarketing Agent pursuant to the Remarketing
Agreement), the Treasury Portfolio Interest or the Treasury Securities at
maturity, as the case may be, to be paid upon settlement of such Holder's
obligations to purchase Ordinary Shares under the Purchase Contract, shall be
paid on the Purchase Contract Settlement Date by the Collateral Agent to the
Company in satisfaction of such Holder's obligations under such Purchase
Contract and such Holder shall acquire no right, title or interest in such
payments.

         Upon registration of transfer of a Certificate, the transferee shall be
bound (without the necessity of any other action on the part of such transferee)
by the terms of this Agreement, the Purchase Contracts relating to such
Certificate and the Pledge Agreement and the transferor shall be released from
the obligations under this Agreement, the Purchase Contracts relating to the
Certificates so transferred and the Pledge Agreement. The Company covenants and
agrees, and each Holder of a Certificate, by its acceptance thereof, likewise
covenants and agrees, to be bound by the provisions of this paragraph.

Section 5.2 Purchase Contract Adjustment Payments.

         The Company shall pay, on each Payment Date, the Purchase Contract
Adjustment Payments payable in respect of each Purchase Contract to the Person
in whose name a Certificate (or one or more Predecessor Certificates) is
registered at the close of business on the Record Date next preceding such
Payment Date in such coin or currency of the United States as at the time of
payment shall be legal tender for the payment of public and private debts. The
Purchase Contract Adjustment Payments will be payable at the office of the
Purchase Contract Agent in The City of New York maintained for that purpose or,
at the option of the Company, by wire transfer or by check mailed to the address
of the Person entitled thereto at such Person's address as it appears on the
Corporate Units Register or Treasury Units Register.

                                       38
<PAGE>

         Upon the occurrence of a Termination Event, the Company's obligation to
pay Purchase Contract Adjustment Payments (including any accrued Purchase
Contract Adjustment Payments) shall cease.

         Each Certificate delivered under this Agreement upon registration of
transfer of or in exchange for or in lieu of (including as a result of a
Collateral Substitution or the recreation of Corporate Units) any other
Certificate shall carry the right to accrued and unpaid Purchase Contract
Adjustment Payments, and the right to accrue Purchase Contract Adjustment
Payments, which rights were carried by the Purchase Contracts relating to such
other Certificates from the date of issuance to and excluding, the Purchase
Contract Settlement Date, unless such Purchase Contracts have been settled
earlier pursuant to this Agreement.

         In the case of any Units with respect to which (1) Cash Settlement of
the related Purchase Contract is effected on the fifth Business Day immediately
preceding the Purchase Contract Settlement Date, (2) Early Settlement of the
related Purchase Contract is effected on an Early Settlement Date or (3) Merger
Early Settlement of the related Purchase Contract is effected on a Merger Early
Settlement Date, in each case, on a date that is after any Record Date and on or
prior to the next succeeding Payment Date, Purchase Contract Adjustment Payments
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Cash Settlement, Early Settlement or Merger Early
Settlement, as the case may be, and such Purchase Contract Adjustment Payments
shall be paid to the Person in whose name the Certificate evidencing such Units
(or one or more Predecessor Certificates) is registered at the close of business
on such Record Date. Except as otherwise expressly provided in the immediately
preceding sentence, in the case of any Units with respect to which Cash
Settlement, Early Settlement or Merger Early Settlement of the related Purchase
Contract is effected on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date, an Early Settlement Date or a Merger Early
Settlement Date, respectively, Purchase Contract Adjustment Payments that would
otherwise be payable after the fifth Business Day preceding the Purchase
Contract Settlement Date, after the Early Settlement Date or after the Merger
Early Settlement Date, respectively, with respect to such Purchase Contract
shall not be payable.

         Promptly after the calculation of any adjustment to the Purchase
Contract Adjustment Payments arising from a Reset Transaction, the Company shall
give the Purchase Contract Agent notice thereof. All calculations and
determinations of the Adjusted Purchase Contract Adjustment Payment Rate shall
be made by the Company or its agent in good faith and the Purchase Contract
Agent shall have no responsibility with respect thereto. The Purchase Contract
Agent shall not at any time be under any duty or responsibility to any Holder of
Units to determine whether any facts exist which may require any adjustment to
the Purchase Contract Adjustment Payments, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the
method employed in making the same.

Section 5.3 Payment of Purchase Price; Remarketing.

         (a) Unless a Termination Event has occurred or a Holder has settled the
related Purchase Contract through a Cash Settlement pursuant to Section 5.8, an
Early Settlement pursuant to Section 5.9 or a Merger Early Settlement pursuant
to Section 5.10, the settlement of the Purchase Contract relating to a Unit will
be made by Remarketing in accordance with this Section 5.3.

         (b) The Company shall engage _______________, or another nationally
recognized investment bank, to act as Remarketing Agent (the "Remarketing
Agent") pursuant to the Remarketing Agreement to remarket (1) the Pledged Debt
Securities comprising part of the Corporate Units, other than those Pledged Debt
Securities of Holders that have elected not to participate in the Remarketing
pursuant to Section 5.3(e) below, and (2) the Separated Debt Securities of
holders of Separated Debt Securities that have elected to participate in the
Remarketing pursuant to paragraph ___ of the Indenture Officers' Certificate and
Section ___ of the Pledge Agreement (the Debt Securities described in clauses
(1) and (2) collectively being referred to as the "Remarketing Debt Securities")
pursuant to the Remarketing Procedures.

         On the seventh Business Day prior to the Initial Remarketing Date, the
Company shall give notice of Remarketing in an Authorized Newspaper, including
the specific U.S. Treasury security or securities (including the CUSIP number
and/or the principal terms of such Treasury security or securities) that must be
delivered by Holders of Corporate Units that elect not to participate in the
Remarketing pursuant to Section 5.3(e) below, no later than 5:00 p.m. (New York
City time) on the Election Date. Not later than 15 calendar days nor more than
30 calendar days prior to the Initial Remarketing Date, the Company shall
request DTC (or any successor Depositary), to notify its Beneficial Owners or
Depositary Participants holding Corporate Units or Separate Debt Securities of
the impending Remarketing.

         The Purchase Contract Agent shall notify, by 11:00 a.m. (New York City
time), on the Business Day immediately preceding the Initial Remarketing Date,
the Remarketing Agent, the Collateral Agent, the Trustee and the Company, by use
of a notice substantially in the form of Exhibit G hereto, of the aggregate
principal amount of Pledged Debt Securities of Corporate Unit Holders to be
remarketed on the Initial Remarketing Date or Subsequent Remarketing Date, as
applicable, and the Collateral Agent, pursuant to the Pledge Agreement, having
separately notified the Remarketing Agent, the Trustee and the Company of the
aggregate principal amount of Separated Debt Securities to be included on the
Initial Remarketing Date or Subsequent Remarketing Date, as applicable, by 11:00
a.m. (New York City time), on the Business Day immediately preceding the Initial
Remarketing Date, shall concurrently therewith, pursuant to the Pledge
Agreement, deliver for Remarketing to the Remarketing Agent all Remarketing Debt
Securities. Upon receipt of such notice from the Purchase Contract Agent and the
Collateral Agent and such Remarketing Debt Securities from the Collateral Agent,
the Remarketing Agent, pursuant to the Remarketing Agreement, will, use its
commercially reasonable efforts to remarket such Remarketing Debt Securities on
such date pursuant to the Remarketing Procedures and the Remarketing Agreement.

         If there has been a Successful Initial Remarketing or a Successful
Subsequent Remarketing, the Remarketing Agent will on the Remarketing Date of
such Remarketing (i) deduct and retain for itself as the remarketing fee for
itself an amount not exceeding [ ] basis points ([ ]%) of the principal amount
of each remarketed Remarketing Debt Security (the "Remarketing Fee"), (ii) use
the remaining proceeds attributable to the Pledged Debt Securities from such
Successful Remarketing to purchase the appropriate U.S. Treasury securities (the
"Treasury Portfolio" and the related interest in the Treasury Portfolio
applicable to a Corporate Unit, the "Treasury Portfolio Interest") with the
CUSIP numbers, if any, selected by Remarketing Agent, described in clauses
(1)(i) and (2)(i) of the definition of Remarketing Value related to the Debt
Securities of Holders of Corporate Units that were remarketed, (iii) if any
Separated Debt Securities were remarketed, remit to the Collateral Agent, along
with notification thereof, for payment to the holders of such Separated Debt
Securities sold in the Remarketing the remaining proceeds from such Successful
Remarketing equal to the amounts described in clauses (1)(ii) and (2)(ii) of the
definition of Remarketing Value and (iv) if there then remains any proceeds from
such Successful Remarketing, after the application of such proceeds as set forth
in clauses (i) through (iii) above of this sentence, then remit, along with
notification thereof, any such remaining proceeds to the Purchase Contract Agent
for the benefit of holders of the remarketed Debt Securities and to the
Collateral Agent for the benefit of the holders of such Separated Debt
Securities, on a pro rata basis, provided, however, that if such Successful
Remarketing is consummated after 4:30 p.m. (New York City time) on such
Remarketing Date and, despite using its commercially reasonable efforts, the
Remarketing Agent cannot cause the applications of the proceeds specified above
to occur on such Remarketing Date, then the Remarketing Agent may make such
applications and remittances on the next succeeding Business Day. Holders of
Remarketing Debt Securities that are so remarketed will not otherwise be
responsible for the payment of any remarketing fee or expenses in connection
with the Remarketing. On the Remarketing Settlement Date, the Remarketing Agent
shall deliver the Treasury Portfolio to the Collateral Agent. The Collateral
Agent, for the benefit of the Company, will thereupon apply such Treasury
Portfolio, in accordance with the Pledge Agreement, to secure such Holders'
obligations under the Purchase Contracts.

         In the event that all or any portion of the Pledged Treasury Portfolio
Interest matures before the Purchase Contract Settlement Date, the Collateral
Agent shall invest the proceeds therefrom in Permitted Investments in accordance
with the Pledge Agreement. The Collateral Agent shall cause the Securities
Intermediary to remit, on the Purchase Contract Settlement Date, a portion of
the proceeds of the maturing Pledged Treasury Portfolio Interest and of the
investment earnings from the related investment in Permitted Investments, in
each case, in an amount equal to the Treasury Portfolio Return to the Purchase
Contract Agent for the benefit of the Holders of the related Corporate Units
when received. Without receiving any instruction from any such Holder of
Corporate Units, the Collateral Agent shall apply, on the Purchase Contract
Settlement Date, the proceeds of the maturing Pledged Treasury Portfolio
Interest and of the investment earnings from the related investment in Permitted
Investments in an aggregate amount equal to the aggregate Purchase Price
applicable to such Corporate Units to satisfy in full such Holder's obligations
to pay the Purchase Price to purchase the Ordinary Shares under the related
Purchase Contracts on the Purchase Contract Settlement Date. In the event the
sum of the proceeds from the related Pledged Treasury Portfolio Interest and the
investment earnings from the related investment in Permitted Investments exceeds
the sum of the related Treasury Portfolio Return and the aggregate Purchase
Price of the Purchase Contracts being settled thereby, the Collateral Agent
shall instruct the Securities Intermediary to distribute such excess, when
received, to the Purchase Contract Agent for distribution to the Holders whose
Purchase Contracts were settled with such proceeds, on a pro rata basis.

                                       41
<PAGE>

         If, by 4:00 p.m. (New York City time), on the ninth Business Day
preceding the Purchase Contract Settlement Date, the Remarketing Agent, despite
using its commercially reasonable efforts, has been and is unable to remarket
all of the Remarketing Debt Securities tendered for purchase at a price equal to
at least the Remarketing Value, the Remarketing Agent shall Transfer to the
Collateral Agent, along with notification thereof, by the sixth Business Day
preceding the Purchase Contract Settlement Date, the Pledged Debt Securities
that that were to be remarketed in the Initial or Subsequent Remarketing,
whereupon the Collateral Agent shall, for the benefit of the Company, apply such
Pledged Debt Securities, to secure the obligation of the related Holders of
Corporate Units to purchase Ordinary Shares under the related Purchase
Contracts.

         (c) Unless a Termination Event has occurred or a Holder has settled the
related Purchase Contract through a Cash Settlement, an Early Settlement or a
Merger Early Settlement, or a Successful Initial Remarketing or a Successful
Subsequent Remarketing has occurred, such Holder shall be deemed to have
consented to the Remarketing of such Holder's Pledged Debt Securities in the
Final Remarketing on the Final Remarketing Date. The Purchase Contract Agent,
shall by 11:00 a.m. (New York City time), on the Business Day immediately
preceding the Final Remarketing Date, notify the Remarketing Agent, the
Collateral Agent, the Trustee and the Company, by use of a notice substantially
in the form of Exhibit G hereto, of such event and of the aggregate principal
amount of Pledged Debt Securities of Corporate Unit Holders to be remarketed on
the Final Remarketing Date, whereupon the Collateral Agent, shall concurrently
therewith, without any instruction from such Holder of Corporate Units with
respect to their Pledged Debt Securities, transfer the Remarketing Debt
Securities to the Remarketing Agent for Remarketing. Upon receiving such
Remarketing Debt Securities, the Remarketing Agent, pursuant to the terms of the
Remarketing Agreement, will use its commercially reasonable efforts to remarket
such Remarketing Debt Securities on the Final Remarketing Date.

                                       42
<PAGE>

         If a Successful Final Remarketing shall have occurred, the Remarketing
Agent will on the Remarketing Date (i) deduct and retain for itself the
Remarketing Fee, pursuant to the Remarketing Agreement, (ii) cause the remaining
proceeds of the Remarketing with respect to the Pledged Debt Securities in an
amount equal to the aggregate principal amount of such Debt Securities to be
delivered to the Collateral Agent, on the Remarketing Settlement Date, (iii) if
any Separated Debt Securities were remarketed, remit, along with notification
thereof, to the Collateral Agent for payment to the holders of such Separated
Debt Securities sold in the Remarketing the remaining proceeds from such
Successful Remarketing attributable to the Separated Debt Securities in an
amount equal to the principal amount of such Debt Securities and (iv) if there
remains any proceeds from such Successful Remarketing, after the application of
such proceeds as set forth in clauses (i) through (iv) of this sentence, then
remit, along with notification thereof, such remaining proceeds to the Purchase
Contract Agent for the benefit of the holders of the Pledged Debt Securities and
to the Collateral Agent for the benefit of holders of Separated Debt Securities,
on a pro rata basis, provided, however, that if such Successful Remarketing is
consummated after 4:30 p.m. (New York City time) on such Remarketing Date and,
despite using its commercially reasonable efforts, the Remarketing Agent cannot
cause the applications of the proceeds specified above to occur on such
Remarketing Date, then the Remarketing Agent may make such applications and
remittances on the next succeeding Business Day. Holders of the Remarketing Debt
Securities that are so remarketed will not otherwise be responsible for the
payment of any remarketing fee or expenses in connection with the Remarketing.
The Purchase Contract Agent shall give written directions to the Collateral
Agent, and the Collateral Agent shall instruct the Securities Intermediary, to
apply a portion of the Proceeds with respect to the Pledged Debt Securities from
such Remarketing, on the Purchase Contract Settlement Date, equal to the
aggregate principal amount of such Pledged Debt Securities to satisfy in full
the obligations of such Holders of Corporate Units to pay the Purchase Price to
purchase the Ordinary Shares under the related Purchase Contracts.

         If, (1) by 4:00 p.m. (New York City time), on the Final Remarketing
Date, despite using its commercially reasonable efforts, the Remarketing Agent
cannot remarket the Debt Securities included in the Remarketing at a price equal
to at least the Remarketing Value, or (2) the Remarketing Agent has determined
that the Remarketing may not be consummated as contemplated herein and by the
Remarketing Procedures under applicable law, the Remarketing will be deemed to
have failed (a "Failed Remarketing"). If a Failed Remarketing occurs, the
Remarketing Agent will, pursuant to the Remarketing Agreement, promptly advise
the Trustee, the Purchase Contract Agent, the Collateral Agent, the Company and
the Depositary that a Failed Remarketing has occurred. The Collateral Agent,
under the Pledge Agreement and for the benefit, and on behalf, of the Company,
may exercise its rights as a secured party with respect to such Pledged Debt
Securities, including those actions specified in paragraph (d) below; provided
that, if upon a Failed Remarketing, the Collateral Agent exercises such rights
for the benefit of the Company with respect to such Pledged Debt Securities, any
accumulated and unpaid interest on such Debt Securities will become payable by
the Company to the Purchase Contract Agent for payment to the Holders of the
Corporate Units to which such Pledged Debt Securities relate. Such payment will
be made by the Company on or prior to 11:00 a.m. (New York City time), on the
Purchase Contract Settlement Date in lawful money of the United States by
certified or cashiers' check or wire transfer in immediately available funds
payable to or upon the order of the Purchase Contract Agent. The Company will
cause a notice of any Failed Remarketing to be sent to the holders of all Debt
Securities and to be published in an Authorized Newspaper, in each case, no
later than on the Business Day immediately preceding the Purchase Contract
Settlement Date.

                                       43
<PAGE>

         (d) With respect to any Pledged Debt Securities which are subject of a
Failed Remarketing, the Collateral Agent, for the benefit of the Company, and
upon written direction of the Company as provided in the Pledge Agreement,
reserves all of its rights as a secured party with respect thereto and, subject
to applicable law and paragraph (e) below, may (i) retain such Debt Securities
in full satisfaction of the Holders' obligations under the related Purchase
Contracts or (ii) sell such Debt Securities in one or more public or private
sales.

         (e) A Holder of Corporate Units may elect not to participate in the
Remarketing by creating Treasury Units by notifying the Purchase Contract Agent
of such election and complying with the procedures for creating Treasury Units
set forth in Section 3.13 until 5:00 p.m. (New York City time) on the Election
Date. A Holder that does not so create Treasury Units by delivering the Treasury
Security or Treasury Securities pursuant to this paragraph and Section 3.13
shall be deemed to have elected to participate in any Remarketing.

         (f) In the event that all or any portion of the Pledged Treasury
Securities of Treasury Units matures before the Purchase Contract Settlement
Date, the Collateral Agent shall invest the proceeds therefrom in Permitted
Investments in accordance with the Pledge Agreement.

         Without receiving any instruction from any such Holder of Treasury
Units, the Collateral Agent shall apply, on the Purchase Contract Settlement
Date, the proceeds of the maturing Pledged Treasury Securities and of the
investment earnings from the related investment in Permitted Investments, in
each case, in an amount equal to the aggregate Purchase Price applicable to such
Treasury Units to satisfy in full such Holder's obligations to pay the Purchase
Price to purchase the Ordinary Shares under the related Purchase Contracts on
the Purchase Contract Settlement Date.

         In the event the sum of the proceeds from the related Pledged Treasury
Securities and the investment earnings from the related investment in Permitted
Investments exceeds the aggregate Purchase Price of the Purchase Contracts being
settled thereby, the Collateral Agent shall instruct the Securities Intermediary
to distribute such excess, when received, to the Purchase Contract Agent for
distribution to the Holders whose Purchase Contracts were settled with such
proceeds, on a pro rata basis.

         (g) Any distributions to Holders of excess funds and interest described
in paragraphs (b), (c) and (f) above shall be payable at the office of the
Purchase Contract Agent in The City of New York maintained for that purpose or,
at the option of the Holder, or the holder of Separated Debt Securities, as
applicable, by check mailed to the address of the Person entitled thereto at
such address as it appears on the Register or by wire transfer to an account
specified by the Holder, or the holder of Separated Debt Securities, as
applicable.

                                       44
<PAGE>

         (h) The obligations of each Holder to pay the Purchase Price are
non-recourse obligations and except to the extent paid by Cash Settlement, Early
Settlement or Merger Early Settlement, are payable solely out of the proceeds of
any Collateral pledged to secure the obligations of the Holders, and in no event
shall Holders be liable for any deficiency between such payments and the
Purchase Price.

         (i) Notwithstanding anything to the contrary herein, the Company shall
not be obligated to issue any Ordinary Shares in respect of a Purchase Contract
or deliver any certificates therefor to the Holder of the related Units unless
the Company shall have received payment in full of the aggregate Purchase Price
for the Ordinary Shares to be purchased thereunder by such Holder in the manner
herein set forth, which payment, in the case of Corporate Units upon the
occurrence of a Failed Remarketing, shall occur by the resale of Pledged Debt
Securities or foreclosure on and retention of such Pledged Debt Securities.

Section 5.4 Issuance of Ordinary Shares.

         (a) Unless a Termination Event shall have occurred on or prior to the
Purchase Contract Settlement Date, the applicable Early Settlement Date or the
Merger Early Settlement Date, upon its receipt of payment in full of the
Purchase Price for the Ordinary Shares purchased by Holders pursuant to the
provisions of this Article and subject to Section 5.5(b), the Company shall
issue and deposit with the Company's transfer agent and registrar for its
Ordinary Shares (the "Ordinary Shares Transfer Agent"), for the benefit of the
Holders of the Outstanding Units, one or more certificates representing the
newly issued Ordinary Shares registered in the name of the Purchase Contract
Agent (or its nominee) as custodian for the Holders (such certificates for
Ordinary Shares, together with any dividends or distributions for which a record
date and payment date for such dividend or distribution has occurred after the
applicable Early Settlement Date, the Merger Early Settlement Date or the
Purchase Contract Settlement Date, as the case may be, being hereinafter
referred to as the "Purchase Contract Settlement Fund") to which the Holders are
entitled hereunder. The Company shall furnish to the Purchase Contract Agent the
name and address of the Ordinary Shares Transfer Agent and of any change
thereof.

         (b) Upon surrender of a Certificate to the Purchase Contract Agent on
or after the applicable Early Settlement Date, the Merger Early Settlement Date
or the Purchase Contract Settlement Date, as the case may be, together with
settlement instructions thereon duly completed and executed, the Holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing that number of whole Ordinary Shares which such Holder is entitled
to receive pursuant to the provisions of this Article Five (after taking into
account all Units then held by such Holder), together with cash in lieu of
fractional shares as provided in Section 5.12 and any dividends or distributions
with respect to such shares constituting part of the Purchase Contract
Settlement Fund, but without any interest thereon (or, if such Certificate is
not surrendered to the Purchase Contract Agent; or if no such instructions are
given to the Purchase Contract Agent by the Holder, the Ordinary Shares Agent
shall hold such certificate representing Ordinary Shares, and the Purchase
Contract Agent shall hold such cash in lieu of fractional shares and dividends
or distributions, as applicable, in the name of the Purchase Contract Agent or
its nominee in trust for the benefit of such Holder until the expiration of the
time period specified in the abandoned property laws of the relevant state,
following which the Purchase Contract Agent shall cause such cash to be
delivered to such Holders), and the Certificate so surrendered shall forthwith
be cancelled. Such shares shall be registered by the Ordinary Shares Transfer
Agent in the Company's register for its Ordinary Shares and in accordance with
its customary procedures for issuance of such Ordinary Shares, in the name of
the Holder or the Holder's designee as specified in the settlement instructions
provided by the Holder to the Purchase Contract Agent and forwarded by the
Purchase Contract Agent to the Ordinary Shares Transfer Agent. If any Ordinary
Shares issued in respect of a Purchase Contract are to be registered to a Person
other than the Person in whose name the Certificate evidencing such Purchase
Contract is registered, no such registration shall be made unless the Person
requesting such registration has paid any transfer and other taxes required by
reason of such registration in a name other than that of the registered Holder
of the Certificate evidencing such Purchase Contract or has established to the
satisfaction of the Company that such tax either has been paid or is not
payable.

Section 5.5 Adjustment of Settlement Rate and Early Settlement Rate.

         (a) Adjustments for Dividends, Distributions, Stock Splits, Etc.

                  (1) In case the Company shall pay or make a dividend or other
         distribution on the Ordinary Shares in Ordinary Shares, the Settlement
         Rate in effect or the Early Settlement Rate, as applicable, in effect
         at the opening of business on the Business Day following the date fixed
         for the determination of shareholders entitled to receive such dividend
         or other distribution shall be increased by dividing such Settlement
         Rate by a fraction of which:

                           (i) the numerator shall be the number of Ordinary
                  Shares outstanding at the close of business on the date fixed
                  for such determination; and

                           (ii) the denominator shall be the sum of such number
                  of shares and the total number of shares constituting such
                  dividend or other distribution,

         such increase to become effective immediately after the opening of
         business on the day following the date fixed for such determination.
         For the purposes of this paragraph (1), the number of Ordinary Shares
         at any time outstanding shall not include shares held in the treasury
         of the Company but shall include any shares issuable in respect of any
         scrip certificates issued in lieu of fractions of Ordinary Shares. The
         Company will not pay any dividend or make any distribution on Ordinary
         Shares held in the treasury of the Company.

                                       46
<PAGE>

                  (2) In case the Company shall issue rights, options or
         warrants to all holders of Ordinary Shares (not being available on an
         equivalent basis to Holders of the Units upon settlement of the
         Purchase Contracts relating to such Units) entitling them, for a period
         expiring within 45 days after the record date for the determination of
         shareholders entitled to receive such rights, options or warrants, to
         subscribe for or purchase Ordinary Shares at a price per share less
         than the Current Market Price per share of Ordinary Shares on the date
         fixed for the determination of shareholders entitled to receive such
         rights, options or warrants (other than pursuant to a dividend
         reinvestment plan), the Settlement Rate or the Early Settlement Rate,
         as applicable, in effect at the opening of business on the day
         following the date fixed for such determination shall be increased by
         dividing such Settlement Rate or the Early Settlement Rate, as
         applicable, by a fraction of which:

                           (i) the numerator shall be the number of Ordinary
                  Shares outstanding at the close of business on the date fixed
                  for such determination plus the number of Ordinary Shares
                  which the aggregate of the offering price of the total number
                  of Ordinary Shares so offered for subscription or purchase
                  would purchase at such Current Market Price; and

                           (ii) the denominator shall be the number of Ordinary
                  Shares outstanding at the close of business on the date fixed
                  for such determination plus the number of Ordinary Shares so
                  offered for subscription or purchase,

         such increase to become effective immediately after the opening of
         business on the day following the date fixed for such determination.
         For the purposes of this paragraph (2), the number of Ordinary Shares
         at any time outstanding shall not include shares held in the treasury
         of the Company but shall include any shares issuable in respect of any
         scrip certificates issued in lieu of fractions of Ordinary Shares. The
         Company shall not issue any such rights, options or warrants in respect
         of Ordinary Shares held in the treasury of the Company.

                           (3) In case outstanding Ordinary Shares shall be
                  subdivided or split into a greater number of Ordinary Shares,
                  the Settlement Rate or the Early Settlement Rate, as
                  applicable, in effect at the opening of business on the day
                  following the day upon which such subdivision or split becomes
                  effective shall be proportionately increased, and, conversely,
                  in case outstanding Ordinary Shares shall each be combined
                  into a smaller number of Ordinary Shares, the Settlement Rate
                  or the Early Settlement Rate, as applicable, in effect at the
                  opening of business on the day following the day upon which
                  such combination becomes effective shall be proportionately
                  reduced, such increase or reduction, as the case may be, to
                  become effective immediately after the opening of business on
                  the day following the day upon which such subdivision, split
                  or combination becomes effective.

                  (4) In case the Company shall, by dividend or otherwise,
         distribute to all holders of Ordinary Shares evidences of its
         indebtedness or assets (including securities, but excluding any rights,
         options or warrants referred to in paragraph (2) of this Section
         5.5(a), any dividend or distribution paid exclusively in cash and any
         dividend or distribution referred to in paragraph (1) of this Section
         5.5(a)), the Settlement Rate or the Early Settlement Rate, as
         applicable, in effect, shall be adjusted so that the same shall equal
         the rate determined by dividing the Settlement Rate or the Early
         Settlement Rate, as applicable, in effect immediately prior to the
         close of business on the date fixed for the determination of
         shareholders entitled to receive such distribution by a fraction of
         which:

                           (i) the numerator shall be the Current Market Price
                  per share of Ordinary Shares on the date fixed for such
                  determination less the then fair market value (as determined
                  by the Board of Directors, whose determination shall be
                  conclusive and described in a Board Resolution) of the portion
                  of the assets or evidences of indebtedness so distributed
                  applicable to one share of Ordinary Shares; and

                           (ii) the denominator shall be such Current Market
                  Price per share of Ordinary Shares,

         such adjustment to become effective immediately prior to the opening of
         business on the day following the date fixed for the determination of
         shareholders entitled to receive such distribution. In any case in
         which this paragraph (4) is applicable, paragraph (2) of this Section
         5.5(a) shall not be applicable.

                  (5) In case the Company shall, by dividend or otherwise,
         distribute to all holders of Ordinary Shares (I) cash (excluding any
         cash that is distributed in a Reorganization Event to which Section
         5.5(b) applies or as part of a distribution referred to in paragraph
         (4) of this Section 5.5(a)) in an aggregate amount that, combined
         together with the aggregate amount of any other distributions to all
         holders of Ordinary Shares made exclusively in cash (other than in
         connection with a Reorganization Event) within the 12 months preceding
         the date of payment of such distribution and in respect of which no
         adjustment pursuant to this paragraph (5) or paragraph (6) of this
         Section has been made and (II) the aggregate of any cash plus the fair
         market value (as determined by the Board of Directors, whose
         determination shall be conclusive and described in a Board Resolution)
         of consideration payable in respect of any tender or exchange offer by
         the Company or any of its subsidiaries for all or any portion of
         Ordinary Shares concluded within the 12 months preceding the date of
         payment of the distribution described in Clause (I) above and in
         respect of which no adjustment pursuant to this paragraph (5) or
         paragraph (4) or paragraph (6) of this Section 5.5(a) has been made,
         exceeds 15% of the product of the Current Market Price per share of
         Ordinary Shares on the date for the determination of holders of
         Ordinary Shares entitled to receive such distribution times the number
         of Ordinary Shares outstanding on such date, then, and in each such
         case, immediately after the close of business on such date for
         determination, the Settlement Rate or Early Settlement Rate, as
         applicable, in effect, shall be increased so that the same shall equal
         the rate determined by dividing the Settlement Rate or Early Settlement
         Rate, as applicable, in effect immediately prior to the close of
         business on the date fixed for determination of the shareholders
         entitled to receive such distribution by a fraction of which:

                                       48
<PAGE>

                           (i) the numerator shall be equal to the Current
                  Market Price per share of the Ordinary Shares on the date
                  fixed for such determination less an amount equal to the
                  quotient of (x) the combined amount distributed or payable in
                  the transactions described in clauses (I) and (II) above
                  divided by (y) the number of Ordinary Shares outstanding on
                  such date for determination; and

                           (ii) the denominator shall be equal to the Current
                  Market Price per share of Ordinary Shares on such date for
                  determination.

                  (6) In case a tender or exchange offer made by the Company or
         any subsidiary of the Company for all or any portion of Ordinary Shares
         shall expire and such tender or exchange offer (as amended upon the
         expiration thereof) shall require the payment to shareholders (based on
         the acceptance (up to any maximum specified in the terms of the tender
         or exchange offer) of Purchased Shares) of (I) an aggregate
         consideration having a fair market value (as determined by the Board of
         Directors, whose determination shall be conclusive and described in a
         Board Resolution) that combined together with the aggregate of the cash
         plus the fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive and described in a Board
         Resolution), as of the expiration of such tender or exchange offer, of
         consideration payable in respect of any other tender or exchange offer,
         by the Company or any subsidiary of the Company for all or any portion
         of the Ordinary Shares expiring within the 12 months preceding the
         expiration of such tender or exchange offer and in respect of which no
         adjustment pursuant to paragraph (5) of this Section 5.5(a) or this
         paragraph (6) has been made, and (II) the aggregate amount of any
         distributions to all holders of Ordinary Shares made exclusively in
         cash within the 12 months preceding the expiration of such tender or
         exchange offer and in respect of which no adjustment pursuant to
         paragraph (5) of this Section 5.5(a) or this paragraph (6) has been
         made, exceeds 15% of the product of the Current Market Price per share
         of Ordinary Shares as of the last time (the "Expiration Time") tenders
         could have been made pursuant to such tender or exchange offer (as it
         may be amended) times the number of Ordinary Shares outstanding
         (including any tendered shares) on the Expiration Time, then, and in
         each such case, immediately prior to the opening of business on the day
         after the date of the Expiration Time, the Settlement Rate or Early
         Settlement Rate, as applicable, in effect, shall be adjusted so that
         the same shall equal the rate determined by dividing the Settlement
         Rate or Early Settlement Rate, as applicable, in effect immediately
         prior to the close of business on the date of the Expiration Time by a
         fraction of which:

                                       49
<PAGE>

                           (i) the numerator shall be equal to (A) the product
                  of (1) the Current Market Price per share of Ordinary Shares
                  on the date of the Expiration Time and (2) the number of
                  Ordinary Shares outstanding (including any tendered shares) on
                  the Expiration Time less (B) the amount of cash plus the fair
                  market value (determined as aforesaid) of the aggregate
                  consideration payable to shareholders based on the
                  transactions described in clauses (I) and (II) above (assuming
                  in the case of clause (I) the acceptance, up to any maximum
                  specified in the terms of the tender or exchange offer, of
                  Purchased Shares); and

                           (ii) the denominator shall be equal to the product of
                  (A) the Current Market Price per share of Ordinary Shares as
                  of the Expiration Time and (B) the number of Ordinary Shares
                  outstanding (including any tendered shares) as of the
                  Expiration Time less the number of all shares validly tendered
                  and not withdrawn as of the Expiration Time (the shares deemed
                  so accepted, up to any such maximum, being referred to as the
                  "Purchased Shares").

                  (7) The reclassification of Ordinary Shares into securities
         including securities other than Ordinary Shares (other than any
         reclassification upon a Reorganization Event to which Section 5.5(b)
         applies) shall be deemed to involve:

                                       50
<PAGE>

                           (i) a distribution of such securities other than
                  Ordinary Shares to all holders of Ordinary Shares (and the
                  effective date of such reclassification shall be deemed to be
                  "the date fixed for the determination of shareholders entitled
                  to receive such distribution" and the "date fixed for such
                  determination" within the meaning of paragraph (4) of this
                  Section 5.5(a)); and

                           (ii) a subdivision, split or combination, as the case
                  may be, of the number of Ordinary Shares outstanding
                  immediately prior to such reclassification into the number of
                  Ordinary Shares outstanding immediately thereafter (and the
                  effective date of such reclassification shall be deemed to be
                  "the day upon which such subdivision or split becomes
                  effective" or "the day upon which such combination becomes
                  effective", as the case may be, and "the day upon which such
                  subdivision, split or combination becomes effective" within
                  the meaning of paragraph (3) of this Section 5.5(a)).

                  (8) The "Current Market Price" per share of Ordinary Shares on
         any day means the average of the daily Closing Prices for the five
         consecutive Trading Days selected by the Company commencing not more
         than 30 Trading Days before, and ending not later than, the earlier of
         the day in question and the day before the "ex date" with respect to
         the issuance or distribution requiring such computation. For purposes
         of this paragraph, the term "ex date", when used with respect to any
         issuance or distribution, shall mean the first date on which the
         Ordinary Shares trades regular way on such exchange or in such market
         without the right to receive such issuance or distribution.

                  (9) All adjustments to the Settlement Rate or the Early
         Settlement Rate, as applicable, shall be calculated to the nearest
         1/10,000th of a share of Ordinary Shares (or if there is not a nearest
         1/10,000th of a share, to the next lower 1/10,000th of a share). No
         adjustment in the Settlement Rate or the Early Settlement Rate, as
         applicable, shall be required unless such adjustment would require an
         increase or decrease of at least one percent thereof; provided,
         however, that any adjustments which by reason of this subparagraph are
         not required to be made shall be carried forward and taken into account
         in any subsequent adjustment. If an adjustment is made to the
         Settlement Rate or the Early Settlement Rate, as applicable, pursuant
         to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section
         5.5(a), an adjustment shall also be made to the Applicable Closing
         Price solely to determine which of clauses (1), (2) or (3) of the
         definition of Settlement Rate or the Early Settlement Rate, as
         applicable, in Section 5.1 will apply on the Purchase Contract
         Settlement Date. Such adjustment shall be made by multiplying the
         Applicable Closing Price by a fraction of which the numerator shall be
         the Settlement Rate or the Early Settlement Rate, as applicable, in
         effect immediately after such adjustment pursuant to paragraph (1),
         (2), (3), (4), (5), (6), (7) or (10) of this Section 5.5(a) and the
         denominator shall be the Settlement Rate or the Early Settlement Rate,
         as applicable, in effect immediately before such adjustment; provided,
         however, that if such adjustment to the Settlement Rate or the Early
         Settlement Rate, as applicable, in effect, is required to be made
         pursuant to the occurrence of any of the events contemplated by
         paragraph (1), (2), (3), (4), (5), (7) or (10) of this Section 5.5(a)
         during the period taken into consideration for determining the
         Applicable Closing Price, appropriate and customary adjustments shall
         be made to the Settlement Rate or the Early Settlement Rate, as
         applicable.

<PAGE>

                  (10) The Company may make such increases in the Settlement
         Rate or the Early Settlement Rate, as applicable, in addition to those
         required by this Section 5.5(a), as it considers to be advisable in
         order to avoid or diminish any income tax to any holders of Ordinary
         Shares resulting from any dividend or distribution of stock or issuance
         of rights, options or warrants to purchase or subscribe for stock or
         from any event treated as such for income tax purposes or for any other
         reason.

         (b) Adjustment for Consolidation, Merger or Other Reorganization Event.

                                 In the event of:

                  (i) any consolidation or merger of the Company with or into
         another Person (other than a merger or consolidation in which the
         Company is the continuing corporation and in which the Ordinary Shares
         outstanding immediately prior to the merger or consolidation are not
         exchanged for cash, securities or other property of the Company or
         another corporation);

                  (ii) any sale, transfer, lease or conveyance to another Person
         of the property of the Company as an entirety or substantially as an
         entirety;

                  (iii) any statutory exchange of securities of the Company with
         another Person (other than in connection with a merger or acquisition);
         or

                                       52
<PAGE>

                  (iv) any liquidation, dissolution or winding up of the Company
         other than as a result of or after the occurrence of a Termination
         Event (any such event, a "Reorganization Event"),

the Settlement Rate or Early Settlement Rate, as applicable, in effect, will be
adjusted to provide that each Holder of Units will receive on the Purchase
Contract Settlement Date with respect to each Purchase Contract forming a part
thereof, the kind and amount of securities, cash and other property receivable
upon such Reorganization Event (without any interest thereon, and without any
right to dividends or distribution thereon which have a record date that is
prior to the Purchase Contract Settlement Date) by a Holder of the number of
Ordinary Shares issuable on account of each Purchase Contract if the Purchase
Contract Settlement Date had occurred immediately prior to such Reorganization
Event, assuming such Holder of Ordinary Shares is not a Person with which the
Company consolidated or into which the Company merged or which merged into the
Company or to which such sale or transfer was made, as the case may be (any such
Person, a "Constituent Person"), or an Affiliate of a Constituent Person to the
extent such Reorganization Event provides for different treatment of Ordinary
Shares held by Affiliates of the Company and non-Affiliates and such Holder
failed to exercise his rights of election, if any, as to the kind or amount of
securities, cash and other property receivable upon such Reorganization Event
(provided that if the kind or amount of securities, cash and other property
receivable upon such Reorganization Event is not the same for each share of
Ordinary Shares held immediately prior to such Reorganization Event by other
than a Constituent Person or an Affiliate thereof and in respect of which such
rights of election shall not have been exercised ("non-electing share"), then
for the purpose of this Section the kind and amount of securities, cash and
other property receivable upon such Reorganization Event by each non-electing
share shall be deemed to be the kind and amount so receivable per share by a
plurality of the non-electing shares).

         In the event of such a Reorganization Event, the Person formed by such
consolidation, merger or exchange or the Person which acquires the assets of the
Company or, in the event of a liquidation, dissolution or winding up of the
Company, the Company or a liquidating trust created in connection therewith,
shall execute and deliver to the Purchase Contract Agent an agreement
supplemental hereto providing that the Holders of each Outstanding Unit shall
have the rights provided by this Section 5.5(b). Such supplemental agreement
shall provide for adjustments which, for events subsequent to the effective date
of such supplemental agreement, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section. The above
provisions of this Section shall similarly apply to successive Reorganization
Events.

         (c) All calculations and determinations pursuant to this Section 5.5
shall be made by the Company or its agent and the Purchase Contract Agent shall
have no responsibility with respect thereto.

         Rate or Early Settlement Rate, as applicable and the Applicable Closing
         Price, the method of calculation thereof in reasonable detail, and the
         facts requiring such adjustment and upon which such adjustment is
         based; and

                  (ii) within 10 Business Days following the occurrence of an
         event that requires an adjustment to the Settlement Rate or Early
         Settlement Rate, as applicable and the Applicable Closing Price
         pursuant to Section 5.5 (or if the Company is not aware of such
         occurrence, as soon as practicable after becoming so aware), provide a
         written notice to the Holders of the Units of the occurrence of such
         event and a statement in reasonable detail setting forth the method by
         which the adjustment to the Settlement Rate then or Early Settlement
         Rate, as applicable and the Applicable Closing Price was determined and
         setting forth the adjusted Settlement Rate or Early Settlement Rate, as
         applicable and Applicable Closing Price.

         (b) The Purchase Contract Agent shall not at any time be under any duty
or responsibility to any Holder of Units to determine whether any facts exist
which may require any adjustment of the Settlement Rate or Early Settlement
Rate, as applicable or the Applicable Closing Price, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed in making the same. The Purchase Contract Agent
shall not be accountable with respect to the validity or value (or the kind or
amount) of any Ordinary Shares, or of any securities or property, which may at
the time be issued or delivered with respect to any Purchase Contract; and the
Purchase Contract Agent makes no representation with respect thereto. The
Purchase Contract Agent shall not be responsible for any failure of the Company
to issue, transfer or deliver any Ordinary Shares pursuant to a Purchase
Contract or to comply with any of the duties, responsibilities or covenants of
the Company contained in this Article.

Section 5.7 Termination Event; Notice.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive, and the obligations of the Company to pay, Purchase Contract
Adjustment Payments and the rights and obligations of Holders to purchase
Ordinary Shares, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Purchase Contract Agent or
the Company, if, on or prior to the Purchase Contract Settlement Date, a
Termination Event shall have occurred. Upon and after the occurrence of a
Termination Event, the Units shall thereafter represent the right to receive the

the case of Corporate Units, or Treasury Securities in the case of Treasury
Units, in accordance with the provisions of Section 5.4 of the Pledge Agreement.

no event later than two Business Days thereafter, give written notice to the
Purchase Contract Agent and the Collateral Agent and shall cause written notice
thereof to be given to the Holders, at their addresses as they appear in the
Register.

         Purchase Contract Agent the Pledged Debt Securities, for delivery to
         the Holders of the related Corporate Units who have complied with this
         Section. Any cash received by the Collateral Agent shall be invested
         promptly by the Securities Intermediary in Permitted Investments and

                  (iii) If a Holder of a Corporate Unit fails to notify the
         Purchase Contract Agent of its intention to make a Cash Settlement in
         accordance with paragraph (a)(i) above, or notifies the Purchase
         Contract Agent as provided in paragraph (a)(i) above of its intention
         to pay the Purchase Price in cash but fails to make such payment as

         the third Business Day prior to the Purchase Contract Settlement Date
         pursuant to the Final Remarketing as described in Section 5.3 or, (B)
         if a Failed Remarketing occurs, to the Collateral Agent, for the
         benefit of the Company, and upon written direction of the Company as
         provided in the Pledge Agreement, exercising all of its rights as a
         secured party with respect to any Pledged Debt Securities under the
         Pledge Agreement and, subject to applicable law and Section 5.3(i), by
         either (i) retaining such Debt Securities in full satisfaction of such

                  (iv) By 11:00 a.m. (New York City time), on the fourth
         Business Day immediately preceding the Purchase Contract Settlement
         Date, the Purchase Contract Agent, based on notices received by the
         Purchase Contract Agent pursuant to Section 5.8(a)(i) hereof and notice
         from the Securities Intermediary regarding cash received by it prior to
         such time, shall notify the Remarketing Agent, the Collateral Agent,
         the Trustee and the Company, by use of a notice substantially in the
         form of Exhibit G hereto, of the aggregate principal amount of Pledged
         Debt Securities to be remarketed on the Final Remarketing Date in
         accordance with the procedures set forth in Section 5.3(c).

Settlement of the related Purchase Contract in the manner described in Section
5.9 or a Merger Early Settlement of the related Purchase Contract in the manner
described in Section 5.10, a Termination Event shall have occurred pursuant to

<PAGE>

                  (ii) A Holder of a Treasury Unit who has so notified the
         Purchase Contract Agent of its intention to make a Cash Settlement in
         accordance with paragraph (b)(i) above shall pay the Purchase Price to
         the Securities Intermediary for deposit in the Collateral Account prior
         to 11:00 a.m. (New York City time), on the Business Day immediately
         preceding the Purchase Contract Settlement Date in lawful money of the
         United States by certified or cashiers' check or wire transfer, in each
         case, in immediately available funds payable to or upon the order of
         the Securities Intermediary and the Securities Intermediary shall
         instruct the Collateral Agent to release to the Purchase Contract Agent
         the Pledged Treasury Securities for delivery to the Holders of the
         related Treasury Units who have complied with this Section. Any cash
         received by the Collateral Agent shall be invested promptly by the
         Securities Intermediary in Permitted Investments and paid to the
         Company on the Purchase Contract Settlement Date in settlement of the

         in respect of the investment earnings from the investment in such
         Permitted Investments shall be distributed to the Purchase Contract
         Agent when received for payment to the Holder of the related Treasury
         Units on the Purchase Contract Settlement Date.

                  (iii) If a Holder of a Treasury Unit fails to notify the
         Purchase Contract Agent of its intention to make a Cash Settlement in
         accordance with paragraph (b)(i) above, or does notify the Purchase
         Contract Agent as provided in paragraph (b)(i) above of its intention
         to pay the Purchase Price in cash but fails to make such payment as

         Pledged Treasury Securities held by the Securities Intermediary, the
         principal amount of the Treasury Securities received by the Securities
         Intermediary shall be invested promptly in Permitted Investments. On
         the Purchase Contract Settlement Date, an amount equal to the Purchase
         Price shall be remitted to the Company as payment thereof without
         receiving any instructions from the Holder of the related Treasury
         Units. In the event the sum of the Proceeds from the related Pledged
         Treasury Securities and the investment earnings earned from such
         investments is in excess of the aggregate Purchase Price of the
         Purchase Contracts being settled thereby, the Collateral Agent shall

         Purchase Contract Agent for the benefit of the Holder of the related
         Treasury Units when received.

         (c) Upon Cash Settlement of any Purchase Contract:

                  (i) the Collateral Agent will in accordance with the terms of
         the Pledge Agreement cause the Pledged Debt Securities or the Pledged
         Treasury Securities, as the case may be, relating to the relevant Units
         to be released from the Pledge, free and clear of any security interest
         of the Company, and transferred to the Purchase Contract Agent for
         delivery to the Holder thereof or its designee as soon as practicable;

                                       57
<PAGE>

                  (ii) subject to the receipt thereof, the Purchase Contract
         Agent shall, by book-entry transfer or other appropriate procedures, in
         accordance with written instructions provided by the Holder thereof,
         transfer such Debt Securities or such Treasury Securities, as the case
         may be (or, if no such instructions are given to the Purchase Contract
         Agent by the Holder, the Purchase Contract Agent shall hold such Debt
         Securities or such Treasury Securities, as the case may be, and any
         interest payment thereon, in the name of the Purchase Contract Agent or
         its nominee in trust for the benefit of such Holder until the
         expiration of the time period specified in the abandoned property laws
         of the relevant State) and, in connection with such Debt Securities,
         the Purchase Contract Agent shall have no responsibility to vote or
         take any other consensual action with respect thereto; and

                  (iii) the Company shall cause the number of Ordinary Shares
         issuable upon Cash Settlement of the related Purchase Contracts
         pursuant to Section 5.4, together with any payment in lieu of any
         fraction of a share, as provided in Section 5.12, to the Holder which
         has exercised its right to Cash Settlement, in accordance with Section
         5.4.

Section 5.9 Early Settlement.

         (a) Unless a Holder has effected a Merger Early Settlement of the
related Purchase Contract pursuant to Section 5.10 or a Termination Event shall
have occurred pursuant to Section 5.7, subject to and upon compliance with the
provisions of this Section 5.9, at the option of the Holder thereof, Purchase
Contracts relating to Units may be settled early ("Early Settlement") on or
prior to the Election Date. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts, the Holder of the Certificate
evidencing Units shall deliver such Certificate to the Purchase Contract Agent
at the Corporate Trust Office duly endorsed for transfer to the Company or in
blank with the form of Election to Settle Early on the reverse thereof duly
completed and accompanied by payment (payable to the Company in immediately
available funds) in an amount (the "Early Settlement Amount") equal to:

                  (1) the product of (A) the Stated Amount times (B) the number
         of Purchase Contracts with respect to which the Holder has elected to
         effect Early Settlement; plus

                  (2) if such delivery is made with respect to any Purchase
         Contracts during the period from the close of business on any Record
         Date next preceding any Payment Date to the opening of business on such
         Payment Date, an amount equal to the Purchase Contract Adjustment
         Payments payable on such Payment Date with respect to such Purchase
         Contracts.

                                       58
<PAGE>

         Except as provided in the immediately preceding sentence and subject to
the last paragraph of Section 5.2, no payment shall be made upon Early
Settlement of any Purchase Contract on account of any Purchase Contract
Adjustment Payments accrued on such Purchase Contract or on account of any
dividends on the Ordinary Shares issued upon such Early Settlement. If the
foregoing requirements are first satisfied with respect to Purchase Contracts
relating to any Units at or prior to 5:00 p.m. (New York City time), on a
Business Day, such day shall be the "Early Settlement Date" with respect to such
Units and if such requirements are first satisfied after 5:00 p.m. (New York
City time), on a Business Day or on a day that is not a Business Day, the "Early
Settlement Date" with respect to such Units shall be the next succeeding
Business Day.

         Upon the receipt of such Certificate and Early Settlement Amount from
the Holder, the Purchase Contract Agent shall pay to the Company such Early
Settlement Amount, the receipt of which payment the Company shall confirm in
writing. The Purchase Contract Agent shall then, in accordance with Section 5.6
of the Pledge Agreement, notify the Collateral Agent that (A) such Holder has
elected to effect an Early Settlement, which notice shall set forth the number
of such Purchase Contracts as to which such Holder has elected to effect Early
Settlement, (B) the Purchase Contract Agent has received from such Holder, and
paid to the Company as confirmed in writing by the Company, the related Early
Settlement Amount and (C) all conditions to such Early Settlement have been
satisfied.

         (b) Upon Early Settlement of Purchase Contracts by a Holder of the
related Units, the Company shall issue, and the Holder shall be entitled to
receive, 3.0084 Ordinary Shares, subject to adjustment in the same manner and at
the same time as the Settlement Rate is adjusted pursuant to Section 5.5, on
account of each Purchase Contract as to which Early Settlement is effected (the
"Early Settlement Rate").

         (c) No later than the third Business Day after the applicable Early
Settlement Date, the Company shall cause:

                  (1) the Ordinary Shares issuable upon Early Settlement of the
         related Purchase Contracts to be issued and delivered pursuant to
         Section 5.4, together with payment in lieu of any fraction of a share,
         as provided in Section 5.12; and

                  (2) the related Debt Securities, in the case of Corporate
         Units, or the related Treasury Securities, in the case of Treasury
         Units, to be released from the Pledge by the Collateral Agent and
         transferred, in each case, to the Purchase Contract Agent for delivery
         to the Holder thereof or its designee.

         (d) Upon Early Settlement of any Purchase Contracts, and subject to
receipt by the Ordinary Shares Transfer Agent of Ordinary Shares from the
Company and receipt by the Purchase Contract Agent of the related Debt
Securities, or Treasury Securities, as the case may be, from the Securities
Intermediary, as applicable, the Ordinary Shares Transfer Agent shall, in
accordance with the instructions provided by the Holder thereof on the
applicable form of Election to Settle Early on the reverse of the Certificate
evidencing the related Units as forwarded by the Purchase Contract Agent to the
Ordinary Shares Transfer Agent, deliver to such Holder a certificate or
certificates for the full number of Ordinary Shares issuable upon such Early
Settlement of the related Purchase Contract, pursuant to Section 5.4 and the
Purchase Contract Agent shall transfer to such Holder the related Debt
Securities or Treasury Securities, as the case may be, forming a part of such
Units.

                                       59
<PAGE>

         (e) In the event that Early Settlement is effected with respect to
Purchase Contracts relating to less than all the Units evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the
Purchase Contract Agent shall execute on behalf of the Holder, authenticate and
deliver to the Holder thereof, at the expense of the Company, a Certificate
evidencing the Units as to which Early Settlement was not effected.

         (f) Notwithstanding anything to the contrary contained herein, Holders
may make effect Early Settlement of Treasury Units only in integral multiples of
20 Treasury Units.

authenticate, countersign and deliver to the Holder thereof, at the expense of
the Company, a Certificate evidencing the Units as to which Merger Early
Settlement was not effected.

         (f) Notwithstanding anything to the contrary contained herein, Holders
may effect Merger Early Settlement of Units only in integral multiples of 20
Corporate Units or 20 Treasury Units.

Section 5.11 Optional Remarketing.

         Pursuant to the Indenture and the Remarketing Agreement, holders of
Separated Debt Securities may elect to have such Separated Debt Security
remarketed if such holder, on or prior to 5:00 p.m. (New York City time) on the
Election Date, delivers (a) to the Trustee and the Collateral Agent a notice of
that election, substantially in the form of Exhibit __ of the Indenture
Officers' Certificate and Exhibit __ of the Pledge Agreement, respectively,
specifying the aggregate principal amount of Debt Securities to be remarketed,
and (b) such Separated Debt Securities, by book-entry transfer or other
appropriate procedures, to the Collateral Agent for Remarketing, in each case,
pursuant to the Indenture. Once the holder of such Separated Debt Securities
delivers such notice and Separated Debt Securities as specified in the preceding
sentence, such election may not be withdrawn and may not be conditioned upon the
level at which the Reset Rate is established in the Remarketing; provided,
however, that if such a holder delivers only such a notice but not the Separated
Debt Securities subject to the notice, then none of such holder's Separated Debt
Securities shall be included in the Remarketing.

Section 5.12 No Fractional Shares.

         No fractional shares or scrip representing fractional Ordinary Shares
shall be issued or delivered upon settlement on the Purchase Contract Settlement
Date or upon Early Settlement or Merger Early Settlement of any Purchase
Contracts. If Certificates evidencing more than one Purchase Contract shall be
surrendered for settlement at one time by the same Holder, the number of full
Ordinary Shares which shall be delivered upon settlement shall be computed on
the basis of the aggregate number of Purchase Contracts evidenced by the
Certificates so surrendered. Instead of any fractional share of Ordinary Shares
which would otherwise be deliverable upon settlement of any Purchase Contracts
on the Purchase Contract Settlement Date or upon Early Settlement or Merger
Early Settlement, the Company, through the Purchase Contract Agent, shall make a
cash payment in respect of such fractional interest in an amount equal to the
value of such fractional shares times the Applicable Closing Price. The Company
shall provide the Purchase Contract Agent from time to time with sufficient
funds to permit the Purchase Contract Agent to make all cash payments required
by this Section 5.12 in a timely manner. Promptly after the calculation of the
Applicable Closing Price, the Company shall give the Purchase Contract Agent
notice thereof. All calculations and determinations of the Applicable Closing
Price shall be made by the Company or its agent and the Purchase Contract Agent
shall have no responsibility with respect thereto.

Section 5.13 Charges and Taxes.

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the Ordinary Shares pursuant to the
Purchase Contracts; provided, however, that the Company shall not be required to
pay any such tax or taxes which may be payable in respect of any exchange of or
substitution for a Certificate evidencing a Unit or any issuance of a share of
Ordinary Shares in a name other than that of the registered Holder of a
Certificate surrendered in respect of the Units evidenced thereby, other than in
the name of the Purchase Contract Agent, as custodian for such Holder, and the
Company shall not be required to issue or deliver such share certificates or
Certificates unless the Person or Persons requesting the transfer or issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

of Purchase Contract Adjustment Payments pursuant to Section 5.9(a)), to receive
each Purchase Contract Adjustment Payment with respect to the Purchase Contract
constituting a part of such Units on the respective Payment Date for such Units

each such case, to institute suit for the enforcement of any such Purchase
Contract Adjustment Payment and right to purchase Ordinary Shares, and such

Section 6.2 Restoration of Rights and Remedies.

         If any Holder has instituted any proceeding to enforce any right or
remedy under this Agreement and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to such Holder, then
and in every such case, subject to any determination in such proceeding, the
Company and such Holder shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of such Holder
shall continue as though no such proceeding had been instituted.

of mutilated, destroyed, lost or stolen Certificates in the last paragraph of

Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 6.4 Delay or Omission Not Waiver.

         No delay or omission of any Holder to exercise any right or remedy upon
a default shall impair any such right or remedy or constitute a waiver of any
such right. Every right and remedy given by this Article or by law to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Holders.

Section 6.5 Undertaking for Costs.

         All parties to this Agreement agree, and each Holder of Corporate Units
or Treasury Units, by its acceptance of such Corporate Units or Treasury Units,
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Agreement, or in
any suit against the Purchase Contract Agent for any action taken, suffered or
omitted by it as Purchase Contract Agent, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section shall not apply to any suit
instituted by the Company, to any suit instituted by the Purchase Contract
Agent, to any suit instituted by any Holder, or group of Holders, holding in the
aggregate more than 10% of the Outstanding Units, or to any suit instituted by
any Holder for the enforcement of interest payable on any Debt Securities or
Purchase Contract Adjustment Payments on any Purchase Contract on or after the
respective Payment Date therefor in respect of any Units held by such Holder, or
for enforcement of the right to purchase Ordinary Shares under the Purchase
Contracts constituting part of any Units held by such Holder.

it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Agreement; and the Company expressly waives (to the extent
that it may lawfully do so) all benefit or advantage of any such law and

herein granted to the Purchase Contract Agent or the Holders, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

         hereunder, and to each Purchase Contract Agent, custodian and other
         Person employed to act hereunder;

                  (8) the Purchase Contract Agent shall not be liable for any

Unit for at least six months may, on behalf of himself and all others similarly
situated, petition, at the expense of the Company, any court of competent
jurisdiction for the removal of the Purchase Contract Agent and the appointment
of a successor Purchase Contract Agent.

         (e) If the Purchase Contract Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Purchase
Contract Agent for any cause, the Company, by a Board Resolution, shall promptly
appoint a successor Purchase Contract Agent and shall comply with the applicable
requirements of Section 7.10. If no successor Purchase Contract Agent shall have
been so appointed by the Company and accepted appointment in the manner required
by Section 7.10, any Holder who has been a bona fide Holder of a Unit for at
least six months may, on behalf of itself and all others similarly situated,
petition, at the expense of the Company, any court of competent jurisdiction for

Contract Agent an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Purchase Contract Agent shall become
effective and such successor Purchase Contract Agent, without any further act,
deed or conveyance, shall become vested with all the rights, powers, agencies
and duties of the retiring Purchase Contract Agent; but, on the request of the
Company or the successor Purchase Contract Agent, such retiring Purchase
Contract Agent shall, upon payment of its charges, execute and deliver an

Section 9.1 When Company May Merge, Etc.

         The Company shall not consolidate with or merge into, or sell, lease
(for a term extending beyond the last stated maturity of the Units and the Debt
Securities then Outstanding) or convey all or substantially all of its assets
to, any Person or group of Affiliated Persons in one transaction or a series of

agreements, in form satisfactory to the Purchase Contract Agent, all the
obligations of the Company with respect to the Units and this Agreement, and the
Company or the successor or transferee Person, as the case may be, (i) [shall be
a Corporation organized and existing under the laws of one of the states in the
United States and (ii)] shall not, immediately after such consolidation or
merger or sale, lease or conveyance, be in default in the performance or any
covenant or condition hereunder or under any of the Units. The Company shall
deliver to the Purchase Contract Agent an Officers' Certificate (as defined in

conveyance and such supplemental agreement comply with this Agreement and that
all conditions precedent to the consummation of any such consolidation, or
merger, or any sale, lease or conveyance have been met.

         Upon any consolidation or merger, or any sale, lease or conveyance of
all or substantially all of the assets of the Company in accordance with Section
9.1, the successor corporation or the transferee corporation formed by such
consolidation or into which the Company is merged or to which such transfer is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Agreement with the same effect as if such
successor corporation had been named as the Company herein.

                                       76
<PAGE>

         Such successor or transferee Person thereupon may cause to be signed,
and may issue either in its own name or in the name of Endurance Specialty
Holdings Ltd., any or all of the Certificates evidencing Units issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Purchase Contract Agent; and, upon the order of such successor
or such transferee Person, instead of the Company, and subject to all the terms,
conditions and limitations in this Agreement prescribed, the Purchase Contract
Agent shall authenticate and execute on behalf of the Holders and deliver any
Certificates which previously shall have been signed and delivered by the
officers of the Company to the Purchase Contract Agent for authentication and
execution, and any Certificate evidencing Units which such successor corporation
or transferee corporation thereafter shall cause to be signed and delivered to
the Purchase Contract Agent for that purpose. All the Certificates issued shall
in all respects have the same legal rank and benefit under this Agreement as the
Certificates theretofore or thereafter issued in accordance with the terms of
this Agreement as though all of such Certificates had been issued at the date of
the execution hereof.

         In case of any such merger, consolidation, share exchange, sale,
assignment, transfer, lease or conveyance such change in phraseology and form
(but not in substance) may be made in the Certificates evidencing Units
thereafter to be issued as may be appropriate.

entirety, or substantially the entirety, thereof; or (b) the approval by the
Company of, or the consent by the Company to, any consolidation or merger to
which any Restricted Subsidiary (as defined in the Original Indenture) or any
other subsidiary or affiliate of the Company may be a party or any conveyance,
transfer or lease by any Subsidiary (as defined in the Original Indenture) or
any such other subsidiary or affiliate of any of its assets.

                 (FORM OF REVERSE OF CORPORATE UNIT CERTIFICATE)

1. Purchase Contract Agreement; Purchase Contracts.

         Each Purchase Contract evidenced hereby is being issued under and
governed by a Purchase Contract Agreement, dated as of [DATE] (as may be
amended, modified or supplemented from time to time pursuant to the terms
thereof, the "Purchase Contract Agreement"), between the Company and [ ], as
Purchase Contract Agent (including its successors thereunder, the "Purchase
Contract Agent"), to which Purchase Contract Agreement and amended, modified or
supplemental agreements thereto reference is hereby made for a description of
the respective rights, limitations of rights, obligations, duties and immunities
thereunder of the Purchase Contract Agent, the Company, and the Holders and of
the terms upon which the Corporate Unit Certificates are, and are to be,
executed and delivered. The terms of this Corporate Unit Certificate include
those stated herein and in the Purchase Contract Agreement. To the extent
permitted by applicable law, in the event of an inconsistency between this
Corporate Unit Certificate and the Purchase Contract Agreement, the terms of the
Purchase Contract Agreement shall control. Capitalized terms used but not
defined herein have the meanings ascribed thereto in the Purchase Contract
Agreement.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate Unit Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of Ordinary Shares equal to the Settlement Rate then in effect
unless on or prior to the Purchase Contract Settlement Date, there shall have
occurred a Termination Event, an Early Settlement or a Merger Early Settlement
with respect to the Units of which such Purchase Contract is a part. The
"Settlement Rate" is equal to:

                  (1)      if the Applicable Closing Price (as defined below)
                           per share is equal to or greater than $____ (the
                           "Threshold Appreciation Price"), _____ Ordinary
                           Shares per Purchase Contract;

                  (2)      if the Applicable Closing Price per share is less
                           than the Threshold Appreciation Price but greater
                           than $____ (the "Reference Price"), the number of
                           Ordinary Shares determined by dividing the Stated
                           Amount by the Applicable Closing Price; and

                  (3)      if the Applicable Closing Price per share is less
                           than or equal to the Reference Price, _____ Ordinary
                           Shares per Purchase Contract,

in each case subject to adjustment as provided in the Purchase Contract
Agreement.

         No fractional Ordinary Shares will be issued upon settlement of
Purchase Contracts, as provided in the Purchase Contract Agreement.

                                      A-5
<PAGE>

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Corporate Unit Certificate shall pay the Purchase Price for the
Ordinary Shares purchased pursuant to each Purchase Contract evidenced hereby by
(i) effecting a Cash Settlement, an Early Settlement or Merger Early Settlement
or (ii) application of payments received in respect of the Pledged Treasury
Portfolio Interest acquired from the proceeds of a Remarketing of the related
Pledged Debt Securities relating to the Corporate Units represented by this
Corporate Unit Certificate. As provided in the Purchase Contract Agreement, upon
the occurrence of a Failed Remarketing, the Collateral Agent shall exercise, for
the benefit of the Company, its rights as a secured creditor with respect to the
Pledged Debt Securities related to this Corporate Unit Certificate and, subject
to applicable law, may (i) retain such Pledged Debt Securities in full
satisfaction of the Holders' obligations under the Purchase Contracts or (ii)
sell such Pledged Debt Securities in one or more public or private sales, the
proceeds, if any, of such sale to constitute full satisfaction of the Holders'
obligations under the Purchase Contracts. With respect to such Pledged Debt
Securities which are the subject of a Failed Remarketing, any accrued and unpaid
interest payments on such Pledged Debt Securities will become payable by the
Company to the Holder of this Corporate Unit Certificate in the manner provided
for in the Purchase Contract Agreement.

         The Company shall not be obligated to issue any Ordinary Shares in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the Ordinary Shares to be purchased thereunder in the manner set forth in the
Purchase Contract Agreement which payment, in the case of a Failed Remarketing
shall occur by the resale of Pledged Debt Securities or foreclosure on and
retention of such Pledged Debt Securities pursuant to the Purchase Contract
Agreement and the Pledge Agreement.

         2. Termination Event; Early Settlement; Merger Early Settlement.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive, and the obligation of the Company to pay, Purchase Contract
Adjustment Payments, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Purchase Contract Agent or
the Company, if, on or prior to the Purchase Contract Settlement Date, a
Termination Event shall have occurred. Upon the occurrence of a Termination
Event, the Company shall promptly but in no event later than two Business Days
thereafter give written notice to the Purchase Contract Agent, the Collateral
Agent and the Holders, at their addresses as they appear in the Corporate Units
Register. Upon the occurrence of a Termination Event, the Collateral Agent shall
release the Debt Securities or Pledged Treasury Portfolio Interest, as the case
may be, from the Pledge in accordance with the provisions of the Pledge
Agreement. A Corporate Unit shall thereafter represent the right to receive the
Debt Security forming a part of such Corporate Unit in accordance with the terms
of the Purchase Contract Agreement and the Pledge Agreement.

                                      A-6
<PAGE>

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
relating to Units may be settled early ("Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Corporate
Unit Certificate, the Holder of this Corporate Unit Certificate shall deliver
this Corporate Unit Certificate to the Purchase Contract Agent at the Corporate
Trust Office duly endorsed for transfer to the Company or in blank with the form
of Election to Settle Early set forth below duly completed and accompanied by
payment in the form of immediately available funds payable to the order of the
Company in an amount (the "Early Settlement Amount") equal to:

                  (1)      the product of (A) the Stated Amount times (B) the
                           number of Purchase Contracts with respect to which
                           the Holder has elected to effect Early Settlement,
                           plus

                  (2)      if such delivery is made with respect to any Purchase
                           Contracts during the period from the close of
                           business on any Record Date for any Payment Date to
                           the opening of business on such Payment Date, an
                           amount equal to the Purchase Contract Adjustment
                           Payments payable on such Payment Date with respect to
                           such Purchase Contracts.

         Upon Early Settlement of Purchase Contracts by a Holder of the related
Units, the Pledged Debt Securities relating to such Units shall be released from
the Pledge as provided in the Pledge Agreement and the Holder shall be entitled
to receive a number of Ordinary Shares on account of each Purchase Contract
forming part of a Corporate Unit as to which Early Settlement is effected equal
to the Early Settlement Rate. The Early Settlement Rate shall initially be equal
to _____ Ordinary Shares per Purchase Contract and shall be adjusted in the same
manner and at the same time as the Settlement Rate is adjusted as provided in
the Purchase Contract Agreement.

         3. Creation of Treasury Units; Recreation of Corporate Units.

         A holder of a Corporate Unit may substitute for the Pledged Debt
Securities securing its obligation under the related Purchase Contract Treasury
Securities in an aggregate principal amount at maturity equal to the aggregate
principal amount of the Pledged Debt Securities in accordance with the terms of
the Purchase Contract Agreement and the Pledge Agreement. From and after such
Collateral Substitution, the Units for which such Pledged Treasury Securities
secures the Holder's obligation under the Purchase Contract shall be referred to
as "Treasury Units." A Holder may make such Collateral Substitution only in
integral multiples of 20 Corporate Units for 20 Treasury Units. Such Collateral
Substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, this Corporate Unit
Certificate shall not represent more than __________ Corporate Units, or if in
the form of a Global Certificate, such other maximum amount as shall at the time
be prescribed by the applicable Depositary. All such adjustments to the
equivalent aggregate principal amount of this Corporate Unit Certificate if a
Global Certificate shall be duly recorded by placing an appropriate notation on
the Schedule as may be attached hereto.

                                      A-7
<PAGE>

         A Holder of Treasury Units may recreate Corporate Units by delivering
to the Securities Intermediary Debt Securities with an aggregate principal
amount equal to the aggregate principal amount at maturity of the Pledged
Treasury Securities in exchange for the release of such Pledged Treasury
Securities in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement. Holders may recreate Corporate Units only in integral
multiples of 20 Corporate Units.

         4. Registered Form; Denomination; Registration, Transfer and Exchange.

         The Corporate Unit Certificates are issuable only in registered form
and only in denominations of a single Corporate Unit and any integral multiple
thereof. The transfer of any Corporate Unit Certificate will be registered and
Corporate Unit Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate Units Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Purchase Contract Agent may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. A Holder who
elects to substitute a Treasury Security for Debt Securities, thereby creating
Treasury Units, shall be responsible for any fees or expenses payable in
connection therewith. Except as provided in the Purchase Contract Agreement, for
so long as the Purchase Contract relating to any Corporate Units remains in
effect, such Corporate Units shall not be separable into their constituent
parts, and the rights and obligations of the Holder of such Corporate Unit in
respect of the Debt Security or Treasury Portfolio Interest, as the case may be,
and Purchase Contract constituting such Corporate Units may be transferred and
exchanged only as Corporate Units.

         Upon registration of transfer of this Corporate Unit Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Purchase Contract Agent
pursuant to the Purchase Contract Agreement), under the terms of the Purchase
Contract Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts
evidenced by this Corporate Unit Certificate. The Company covenants and agrees,
and the Holder, by its acceptance hereof, likewise covenants and agrees, to be
bound by the provisions of this paragraph.

         The Company, the Purchase Contract Agent and its Affiliates and any
agent of the Company or the Purchase Contract Agent may treat the Person in
whose name this Corporate Unit Certificate is registered as the owner of the
Corporate Units evidenced hereby for the purpose of receiving payments of
interest payable quarterly on the Debt Securities or Treasury Portfolio Return,
as the case may be, receiving Purchase Contract Adjustment Payments, performance
of the Purchase Contracts and for all other purposes whatsoever, whether or not
any payments in respect thereof be overdue and notwithstanding any notice to the
contrary, and neither the Company, the Purchase Contract Agent nor any such
agent shall be affected by notice to the contrary.

                                      A-8
<PAGE>

         5. Place and Method of Payment.

         The Company shall pay, on each Payment Date, the Purchase Contract
Adjustment Payments payable in respect of each Purchase Contract to the Person
in whose name the Corporate Unit Certificate evidencing such Purchase Contract
is registered at the close of business on the Record Date for such Payment Date.
Purchase Contract Adjustment Payments will be payable at the office of the
Purchase Contract Agent in The City of New York or, at the option of the Company
by wire transfer or by check mailed to the address of the Person entitled
thereto at such address as it appears on the Corporate Units Register.

         6. Authorization of Purchase Contract Agent.

         The Holder of this Corporate Unit Certificate, by its acceptance
hereof, authorizes the Purchase Contract Agent to enter into and perform the
related Purchase Contracts forming part of the Corporate Units evidenced hereby
on its behalf as its attorney-in-fact, expressly withholds any consent to the
assumption (i.e., affirmance) of the Purchase Contracts by the Company or its
trustee in the event that the Company becomes the subject of a case under the
Bankruptcy Code, agrees to be bound by the terms and provisions thereof,
covenants and agrees to perform its obligations under such Purchase Contracts,
consents to the provisions of the Purchase Contract Agreement, authorizes the
Purchase Contract Agent to enter into and perform the Purchase Contract
Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and
consents to the Pledge of the Debt Securities or Treasury Portfolio Interest, as
the case may be, relating to this Corporate Unit Certificate pursuant to the
Pledge Agreement. The Holder further covenants and agrees that, to the extent
and in the manner provided in the Purchase Contract Agreement and the Pledge
Agreement, but subject to the terms thereof, payments in respect of the
aggregate principal amount of the Pledged Debt Securities or Pledged Treasury
Portfolio Interest, as the case may be, shall be paid on the Purchase Contract
Settlement Date by the Collateral Agent to the Company in satisfaction of such
Holder's obligations under such Purchase Contract and such Holder shall acquire
no right, title or interest in such payments.

         7. Amendment.

         The provisions of the Purchase Contract Agreement and this Corporate
Unit Certificate may be amended only as provided in the Purchase Contract
Agreement.

         8. Voting Rights.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of Ordinary Shares. Upon
settlement of the Purchase Contracts, the Holder will be entitled to all of the
rights of a holder of Ordinary Shares, including, without limitation, the right
to vote and receive dividends and other payments and to consent and receive
notice as a shareholder in respect of the meetings of shareholders and for the
election of directors of the Company and for all other matters, and all other
rights whatsoever as a shareholder of the Company. Under the terms of the Pledge
Agreement, the Purchase Contract Agent will be entitled to exercise the voting
and any other consensual rights pertaining to the Pledged Debt Securities upon
behalf of and upon receipt of instructions from the beneficial owners of such
Pledged Debt Securities. Upon receipt of notice of any meeting at which holders
of Debt Securities are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Debt Securities, the Purchase Contract Agent
shall, as soon as practicable thereafter, mail to the Corporate Unit Holders a
notice:

                                      A-9

                           date set by the Purchase Contract Agent therefor
                           (which, to the extent possible, shall be the same
                           date as the record date for determining the holders
                           of Debt Securities entitled to vote) shall be
                           entitled to instruct the Purchase Contract Agent as
                           to the exercise of the voting rights pertaining to
                           the Debt Securities constituting a part of such
                           Holder's Corporate Units; and

                  (3)      stating the manner in which such instructions may be
                           given.

Upon the written request of the Corporate Unit Holders on such record date, the
Purchase Contract Agent shall endeavor insofar as practicable to vote or cause
to be voted, in accordance with the instructions set forth in such requests, the
maximum aggregate principal amount of Debt Securities as to which any particular
voting instructions are received. In the absence of specific instructions from
the Holder of a Corporate Unit, the Purchase Contract Agent shall abstain from
voting the Debt Securities evidenced by such Corporate Units.

         9. Severability.

         If any provision in this Corporate Unit and the Debt Securities is
invalid or unenforceable in any jurisdiction, then, to the fullest extent
permitted by law, (i) the other provisions of this Corporate Unit shall remain
in full force and effect in such jurisdiction and shall be liberally construed
in order to carry out the intentions of the parties hereto as nearly as may be
possible and (ii) the invalidity or unenforceability of any provision of this
Corporate Unit in any jurisdiction shall not in any way affect the validity or
enforceability of such provision in any other jurisdiction.

         10. Governing Law.

         Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Treasury Unit evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder
under the Purchase Contract comprising a portion of such Treasury Units.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury Unit Certificate to purchase, and the Company, to sell, on the Purchase
Contract Settlement Date, at a price equal to $50 in cash (the "Stated Amount"),
a number of Ordinary Shares equal to the Settlement Rate then in effect, unless
on or prior to the Purchase Contract Settlement Date there shall have occurred a
Termination Event or an Early Settlement or Merger Early Settlement with respect
to the Treasury Units of which such Purchase Contract is a part, all as provided
in the Purchase Contract Agreement and more fully described on the reverse
hereof. The purchase price (the "Purchase Price") for the Ordinary Shares
purchased pursuant to each Purchase Contract evidenced hereby, if not paid
earlier, shall be paid on the Purchase Contract Settlement Date by application
of the proceeds from the Treasury Securities at maturity pledged pursuant to the
Pledge Agreement to secure the obligations under such Purchase Contract of the
Holder of the Treasury Units of which such Purchase Contract is a part.

         The Company shall pay on __________, __________, __________ and
__________ of each year (each, a "Payment Date"), commencing [DATE], in respect
of each Purchase Contract forming part of the Treasury Units evidenced hereby,
an amount (the "Purchase Contract Adjustment Payments") equal to (a) if a Reset
Transaction has not occurred, ____% per annum of the Stated Amount or (b)
following the occurrence of a Reset Transaction, if at all, the Adjusted
Purchase Contract Adjustment Payment Rate related to such Reset Transaction
until any such succeeding Reset Transaction shall occur, in either case,
computed on the basis of (i) for any full quarterly period, a 360-day year of
twelve 30-day months, (ii) for any period shorter than a full quarterly period,
a 30-day month and (iii) for periods less than a month, the actual number of
days elapsed per 30-day period). Such Purchase Contract Adjustment Payments
shall be payable to the Person in whose name this Treasury Unit Certificate (or
a Predecessor Treasury Unit Certificate) is registered at the close of business
on the Record Date for such Payment Date.

         Purchase Contract Adjustment Payments will be payable at the office of
the Purchase Contract Agent in The City of New York or, at the option of the
Company, by wire transfer or by check mailed to the address of the Person
entitled thereto as such address appears on the Treasury or Units Register.

         Reference is hereby made to the further provisions set forth on the
reverse hereof, which further provisions shall for all purposes have the same
effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Purchase Contract Agent by manual signature, this Treasury Unit Certificate
shall not be entitled to any benefit under the Purchase Contract Agreement or

                 (FORM OF REVERSE OF TREASURY UNIT CERTIFICATE)

         1. Purchase Contract Agreement; Purchase Contracts.

         Each Purchase Contract evidenced hereby is being issued under and
governed by a Purchase Contract Agreement, dated as of [DATE] (as may be
amended, modified or supplemented from time to time pursuant to the terms
thereof, the "Purchase Contract Agreement") between the Company and [ ], as
Purchase Contract Agent (including its successors thereunder, the "Purchase
Contract Agent"), to which the Purchase Contract Agreement and supplemental
agreements thereto reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Purchase Contract Agent, the Company and the Holders and of the terms upon
which the Treasury Unit Certificates are, and are to be, executed and delivered.
The terms of this Treasury Unit Certificate include those stated herein and in
the Purchase Contract Agreement. To the extent permitted by applicable law, in
the event of an inconsistency between this Treasury Unit Certificate and the
Purchase Contract Agreement, the terms of the Purchase Contract Agreement shall
control. Capitalized terms used but not defined herein have the meanings
ascribed thereto in the Purchase Contract Agreement.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury Unit Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price") a number of Ordinary Shares equal to the Settlement Rate then in effect
unless on or prior to the Purchase Contract Settlement Date, there shall have
occurred a Termination Event, an Early Settlement or a Merger Early Settlement
with respect to the Units of which such Purchase Contract is a part. The
"Settlement Rate" is equal to:

                  (1)      if the Applicable Closing Price (as defined below)
                           per share is equal to or greater than $____ (the
                           "Threshold Appreciation Price"), ____ Ordinary Shares
                           per Purchase Contract;

                  (2)      if the Applicable Closing Price per share is less
                           than the Threshold Appreciation Price but greater
                           than $____ (the "Reference Price"), the number of
                           Ordinary Shares determined by dividing the Stated
                           Amount by the Applicable Closing Price; and

                  (3)      if the Applicable Closing Price per share is less
                           than or equal to the Reference Price, then ____
                           Ordinary Shares per Purchase Contract;

         in each case subject to adjustment as provided in the Purchase Contract
Agreement.

         No fractional Ordinary Shares will be issued upon settlement of
Purchase Contracts, as provided in the Purchase Contract Agreement.

                                      B-4
<PAGE>

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Treasury Unit Certificate shall pay the Purchase Price for the
Ordinary Shares purchased pursuant to each Purchase Contract evidenced hereby by
(i) effecting a Cash Settlement, an Early Settlement or Merger Early Settlement
or (ii) application of payments received in respect of the Pledged Treasury
Securities relating to the Treasury Units represented by this Treasury Unit
Certificate.

         The Company shall not be obligated to issue any Ordinary Shares in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the Ordinary Shares to be purchased thereunder in the manner herein set forth in
the Purchase Contract Agreement.

         2. Termination Event; Early Settlement; Merger Early Settlement.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive, and the obligation of the Company to pay, Purchase Contract
Adjustment Payments, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Purchase Contract Agent or
the Company, if, on or prior to the Purchase Contract Settlement Date, a
Termination Event shall have occurred. Upon the occurrence of a Termination
Event, the Company shall promptly but in no event later than two Business Days
thereafter give written notice to the Purchase Contract Agent, the Collateral
Agent and the Holders, at their addresses as they appear in the Treasury Units
Register. Upon the occurrence of a Termination Event, the Collateral Agent shall
release the Treasury Securities from the Pledge in accordance with the
provisions of the Pledge Agreement. A Treasury Unit shall thereafter represent
the right to receive the interest in the Treasury Security forming a part of
such Treasury Unit, in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
relating to Units may be settled early ("Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Treasury
Unit the Holder of this Treasury Unit Certificate shall deliver this Treasury
Unit Certificate to the Purchase Contract Agent at the Corporate Trust Office
duly endorsed for transfer to the Company or in blank with the form of Election
to Settle Early set forth below duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "Early Settlement Amount") equal to:

                  (1)      the product of (A) the Stated Amount times (B) the
                           number of Purchase Contracts with respect to which
                           the Holder has elected to effect Early Settlement,
                           plus

                  (2)      if such delivery is made with respect to any Purchase
                           Contracts during the period from the close of
                           business on any Record Date for any Payment Date to
                           the opening of business on such Payment Date, an
                           amount equal to the Purchase Contract Adjustment
                           Payments payable on such Payment Date with respect to
                           such Purchase Contracts.

                                      B-5
<PAGE>

Upon Early Settlement of Purchase Contracts by a Holder of the related Units,
the Pledged Treasury Securities relating to such Units shall be released from
the Pledge as provided in the Pledge Agreement and the Holder shall be entitled
to receive a number of Ordinary Shares on account of each Purchase Contract
forming part of a Treasury Unit as to which Early Settlement is effected equal
to the Early Settlement Rate. The Early Settlement Rate shall initially be equal
to ____ Ordinary Shares per Purchase Contract and shall be adjusted in the same
manner and at the same time as the Settlement Rate is adjusted as provided in
the Purchase Contract Agreement.

         3. Recreation of Corporate Units.

         A Holder of Treasury Units may recreate Corporate Units by delivering
to the Collateral Agent Debt Securities with a principal amount equal to the
aggregate principal amount of maturity of the Pledged Treasury Securities in
exchange for the release of such Pledged Treasury Securities in accordance with
the terms of the Purchase Contract Agreement and the Pledge Agreement. From and
after such Collateral Substitution, the Holder's Units shall be referred to as a
"Corporate Units." Such Collateral Substitution may cause the equivalent
aggregate principal amount of this Certificate to be increased or decreased;
provided, however, this Treasury Unit Certificate shall not represent more than
__________ Treasury Units, or if in the form of a Global Certificate, such other
maximum amount as shall at the time be prescribed by the applicable Depositary.
All such adjustments to the equivalent aggregate principal amount of this
Treasury Unit Certificate if a Global Certificate, shall be duly recorded, by
placing an appropriate notation on the Schedule as may be attached hereto. A
Holder who elects to substitute Debt Securities for Treasury Securities, thereby
recreating Corporate Units, shall be responsible for any fees or expenses
associated therewith.

         4. Registered Form; Denominations; Registration, Transfer and Exchange.

         The Treasury Unit Certificates are issuable only in registered form and
only in denominations of a single Treasury Unit and any integral multiple
thereof. The transfer of any Treasury Unit Certificate will be registered and
Treasury Unit Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Treasury Units Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents permitted by
the Purchase Contract Agreement. No service charge shall be required for any
such registration of transfer or exchange, but the Company and the Purchase
Contract Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A Holder who elects to
substitute Debt Securities for a Treasury Security, thereby creating Corporate
