action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company, as
described in Section 13.2. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the

respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

consent, waiver or other Act, but the Company shall have no obligation to do so.
If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other Act may be given before or after such record
date, but only the Holders of record at the close of business on such record
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of outstanding Securities have authorized or
agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other Act, and for that purpose the outstanding Securities
shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date.

or under any such Global Security, and the Depositary or such nominee, as the

Company or the Trustee as the absolute owner and holder of such Global Security
for all purposes whatsoever. Notwithstanding the foregoing, nothing contained
herein shall (A) prevent the Company, the Trustee or any agent of the Company or
the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or such nominee, as the case may be,
or (B) impair, as between the Depositary, its Agent Members and any other person

who was at the time of the execution of the Security an Officer shall bind the
Company, notwithstanding that such individual has ceased to hold such office(s)
prior to the authentication and delivery of such Securities or did not hold such
office(s) at the date of authentication of such Securities.

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

          The Trustee shall authenticate and deliver the Securities for original
issue in an aggregate principal amount of up to $115,000,000 upon one or more
Company Orders without any further action by the Company (other than as
contemplated in Section 13.4 and Section 13.5). The aggregate principal amount
of the Securities due at the Stated Maturity thereof outstanding at any time may
not exceed the amount set forth in the foregoing sentence except as provided in

     in or pursuant to a resolution of the Board of Directors and in conformity
     with the other provisions of this Indenture;

               (iii)    that such Securities, when authenticated and delivered
     by the Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general equity principles;

               (iv)     that all laws and requirements in respect of the

     and delivered by the Company and constitutes a valid and binding agreement
     of the Company enforceable in accordance with its terms.

the Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.

          The Securities shall be issued only in registered form without coupons
and only in denominations of $1,000 of principal amount and any integral
multiple of $1,000.

Trustee). The agreement shall implement the provisions of this Indenture that
relate to such agent. The Company shall notify the Trustee of the name and
address of any such agent. If the Company fails to maintain a Registrar, Paying
Agent or Conversion Agent, the Trustee shall act as such and shall be entitled
to appropriate compensation therefor pursuant to Section 9.7. The Company or any

Conversion Agent or co-registrar.

          The Company hereby initially appoints the Trustee as Registrar, Paying
Agent and Conversion Agent in connection with the Securities.

Agent (other than the Trustee) to agree in writing that the Paying Agent shall
hold in trust for the benefit of Securityholders or the Trustee all cash and
Applicable Stock held by the Paying Agent for the making of payments in respect
of the Securities and shall notify the Trustee of any default by the Company in
making any such payment. If the Company, a Subsidiary or an Affiliate of either
of them acts as Paying Agent, it shall segregate the money and Applicable Stock
held by it as Paying Agent and hold it as a separate trust fund. The Company at
any time may require a Paying Agent to pay all cash and Applicable Stock held by
it to the Trustee, and to account for any funds and Applicable Stock disbursed
by it, and the Trustee may at any time during the continuance of any such
default, upon the written request to the Paying Agent, require such Paying Agent
to forthwith pay to the Trustee all cash and Applicable Stock so held in trust.
Upon doing so, the Paying Agent shall have no further liability for the cash or
Applicable Stock.

          SECTION 2.5. SECURITYHOLDER LISTS.

and at such other times as the Trustee may request in writing a

                                       14
<Page>

list in such form and as of such date as the Trustee may reasonably require of

contained in Section 2.12, when a Security is presented to the Registrar with a
request to register a transfer thereof or to exchange such Security for an equal
principal amount of Securities of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested; PROVIDED,
HOWEVER, that every Security presented or surrendered for registration of
transfer or exchange shall be duly endorsed or accompanied by an assignment form
and, if applicable, a transfer certificate, each in the form included in Exhibit
A attached hereto and in form satisfactory to the Registrar and each duly
executed by the Holder thereof or its attorney duly authorized in writing. To
permit registration of transfers and exchanges, upon surrender of any Security
for registration of transfer or exchange at an office or agency maintained for
such purpose pursuant to Section 2.3, the Company shall execute, and the Trustee
shall authenticate Securities of a like aggregate principal amount at the
Registrar's request. Any transfer or exchange shall be without charge, except
that the Company or the Registrar may require payment of a sum sufficient to pay
all taxes, assessments or other governmental charges that may be imposed in
connection with the transfer or exchange of the Securities from the
Securityholder requesting such transfer or exchange.

          Neither the Company, the Registrar nor the Trustee shall be required
to exchange or register a transfer of (i) any Securities selected for redemption
(except, in the case of Securities to be redeemed in part, the portion thereof
not to be redeemed), (ii) any Securities in respect of which a Repurchase Notice
or a Change of Control Repurchase Notice has been given and not withdrawn by the
Holder thereof in accordance with the terms of this Indenture (except, in the
case of Securities to be repurchased in part, the portion thereof not to be
repurchased) or (iii) any Securities for a period of 15 days before the mailing
of a notice of redemption of Securities to be redeemed.

          All Securities issued upon any transfer or exchange of Securities
shall be valid obligations of the Company, evidencing the same debt and entitled
to the same benefits under this Indenture, as the Securities surrendered upon
such transfer or exchange.

          (b)  Any Registrar appointed pursuant to Section 2.3 shall provide to
the Trustee such information as the Trustee may reasonably require in connection
with the delivery by such Registrar of Securities upon transfer or exchange of
Securities.

          (c)  Each Holder of a Security agrees to indemnify the Company, the
Registrar and the Trustee against any liability that may result from the
transfer, exchange or assignment of such Holder's Security in violation of any
provision of this Indenture and/or applicable United States federal or state
securities law.

          The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between

                                       15
<Page>

or among Agent Members or other beneficial owners of interests in any Global
Security) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements
hereof.

          SECTION 2.7. REPLACEMENT SECURITIES.

          If (a) any mutilated Security is surrendered to the Company, the
Registrar or the Trustee, or (b) the Company, the Registrar and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Security, and there is delivered to the Company, the Registrar and the Trustee
such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company, the Registrar or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount, bearing a certificate number not contemporaneously
outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, or is about to be redeemed by the
Company pursuant to Article III or repurchased by the Company pursuant to
Article IV or V, the Company in its discretion may, instead of issuing a new
Security, pay, redeem or repurchase such Security, as the case may be.

          Upon the issuance of any new Securities under this Section 2.7, the
Company may require the payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee or the Registrar)
connected therewith.

          Every new Security issued pursuant to this Section 2.7 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all benefits of this Indenture equally and proportionately with any
and all other Securities duly issued hereunder.

          The provisions of this Section 2.7 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 Securities.

          SECTION 2.8. OUTSTANDING SECURITIES; DETERMINATIONS OF HOLDERS'
ACTION.

          Securities outstanding at any time are all the Securities
authenticated by the Trustee, except for those cancelled by it, those paid,
redeemed or repurchased pursuant to Section 2.7, those delivered to it for
cancellation and those described in this Section 2.8 as not outstanding.

          A Security does not cease to be outstanding because the Company or an
Affiliate thereof holds the Security; PROVIDED, HOWEVER, that in determining
whether the Holders of the

                                       16
<Page>

requisite principal amount of Securities have given or concurred in any request,
demand, authorization, direction, notice, consent, waiver, or other Act
hereunder, Securities owned by the Company or any other obligor upon the
Securities or any Affiliate of the Company or such other obligor shall be
disregarded and deemed not to be outstanding, except that, in determining
whether the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other Act, only Securities
which a Responsible Officer of the Trustee actually knows to be so owned shall
be so disregarded. Subject to the foregoing, only Securities outstanding at the
time of such determination shall be considered in any such determination.

          If a Security is replaced pursuant to Section 2.7, the replaced
Security ceases to be outstanding unless the Trustee receives proof satisfactory
to it that the replaced Security is held by a bona fide purchaser unaware that
such Security has been replaced.

          If the Paying Agent holds, in accordance with the terms of this
Indenture, prior to 10:00 a.m., New York City time, on a Redemption Date, a
Repurchase Date, a Change of Control Repurchase Date or Stated Maturity, as the
case may be, cash or securities, if permitted hereunder, sufficient to pay
Securities payable on that date, then on such Redemption Date, Repurchase Date,
Change of Control Repurchase Date or Stated Maturity, as the case may be, such
Securities shall cease to be outstanding and interest and Additional Amounts, if
any, on such Securities shall cease to accrue.

          If a Security is converted in accordance with Article XII, then from
and after the time of conversion on the date of conversion, such Security shall
cease to be outstanding and interest and Additional Amounts, if any, on such
Security shall cease to accrue.

          SECTION 2.9. TEMPORARY SECURITIES.

          Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 2.3,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

          SECTION 2.10. CANCELLATION.

                                       17
<Page>

          All Securities surrendered for payment, repurchase by the Company
pursuant to Articles IV or V, conversion, redemption or registration of transfer
or exchange shall, if surrendered to any person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly cancelled
by the Trustee. The Company may not issue new Securities to replace Securities
it has paid or delivered to the Trustee for cancellation or that any Holder has
converted pursuant to Article XII. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of by the Trustee in accordance with the
Trustee's customary procedure.

          SECTION 2.11. PERSONS DEEMED OWNERS.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment (whether in cash or Applicable
Stock) of principal of, Redemption Price, Repurchase Price or Change of Control
Repurchase Price, and interest and Additional Amounts, if any, on, the Security,
for the purpose of receiving cash or Applicable Stock upon conversion and for
all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

          SECTION 2.12. ADDITIONAL TRANSFER AND EXCHANGE REQUIREMENTS.

          (a)  TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.

               (i)      Certificated Securities shall be issued in exchange for
     interests in the Global Securities only if (x) the Depositary notifies the
     Company that it is unwilling or unable to continue as Depositary for the
     Global Securities or if it at any time ceases to be a "clearing agency"
     registered under the Exchange Act, if so required by applicable law or
     regulation and a successor Depositary is not appointed by the Company
     within 90 days, or (y) an Event of Default has occurred and is continuing.
     In either case, the Company shall execute, and the Trustee shall, upon
     receipt of a Company Order (which the Company agrees to deliver promptly),
     authenticate and deliver Certificated Securities in an aggregate principal
     amount equal to the principal amount of such Global Securities in exchange
     therefor. Only Restricted Certificated Securities shall be issued in
     exchange for beneficial interests in Restricted Global Securities, and only
     Unrestricted Certificated Securities shall be issued in exchange for
     beneficial interests in Unrestricted Global Securities. Certificated
     Securities issued in exchange for beneficial interests in Global Securities
     shall be registered in such names and shall be in such authorized
     denominations as the Depositary, pursuant to instructions from its direct
     or indirect participants or otherwise, shall instruct the Trustee. The
     Trustee shall deliver or cause to be delivered such Certificated Securities
     to the Persons in whose name such Securities are so registered. Such
     exchange shall be effected in accordance with the Applicable Procedures.

                                       18
<Page>

               (ii)     Notwithstanding any other provisions of this Indenture
     other than the provisions set forth in Section 2.12(a)(i), a Global
     Security may not be transferred except as a whole by the Depositary to a
     nominee of the Depositary or by a nominee of the Depositary to the
     Depositary or another nominee of the Depositary or by the Depositary or any
     such nominee to a successor Depositary or a nominee of such successor
     Depositary.

          (b)  TRANSFER AND EXCHANGE OF CERTIFICATED SECURITIES. In the event
that Certificated Securities are issued in exchange for beneficial interests in
Global Securities in accordance with Section 2.12(a)(i), and, on or after such
event, Certificated Securities are presented by a Holder to the Registrar with a
request:

          (x)  to register the transfer of the Certificated Securities to a
     person who will take delivery thereof in the form of Certificated
     Securities only; or

          (y)  to exchange such Certificated Securities for an equal principal
     amount of Certificated Securities of other authorized denominations,

such Registrar shall register the transfer or make the exchange as requested;
PROVIDED, HOWEVER, that the Certificated Securities presented or surrendered for
register of transfer or exchange:

               (i)      shall be duly endorsed or accompanied by a written
     instrument of transfer in accordance with the proviso to the first
     paragraph of Section 2.6; and

               (ii)     in the case of a Restricted Certificated Security, such
     request shall be accompanied by the following additional information and
     documents, as applicable:

                        (A)     if such Restricted Certificated Security is
          being delivered to the Registrar by a Holder for registration in the
          name of such Holder, without transfer, or such Restricted Certificated
          Security is being transferred to the Company or a Subsidiary of the
          Company, a certification to that effect from such Holder (in
          substantially the form set forth in the Transfer Certificate);

                        (B)     if such Restricted Certificated Security is
          being transferred to a person the Holder reasonably believes is a QIB
          in accordance with Rule 144A or pursuant to an effective registration
          statement under the Securities Act, a certification to that effect
          from such Holder (in substantially the form set forth in the Transfer
          Certificate); or

                        (C)     if such Restricted Certificated Security is
          being transferred pursuant to an exemption from the registration
          requirements of the Securities Act in accordance with Rule 144 or to
          an institutional "accredited investor" (as defined in Rule 501(a)(1),
          (2), (3) or (7) of Regulation D under the Securities Act) pursuant to
          and in compliance with an exemption from the registration requirements
          under the Securities Act, a certification to that effect from the
          Holder (in substantially the form set forth in the Transfer
          Certificate) and, in the case of a transfer to an institutional
          accredited investor, a certificate containing certain representations
          and warranties (in substantially the form set forth in

                                       19
<Page>

          Exhibit B) and, in either case, if the Company or the Registrar so
          requests, a customary Opinion of Counsel, certificates and other
          information reasonably acceptable to the Company and the Registrar to
          the effect that such transfer does not require registration under the
          Securities Act.

          (c)  TRANSFER OF A BENEFICIAL INTERESTS IN A RESTRICTED GLOBAL
SECURITY FOR A BENEFICIAL INTEREST IN AN UNRESTRICTED GLOBAL SECURITY. Any
person having a beneficial interest in a Restricted Global Security may upon
request, subject to the Applicable Procedures, transfer such beneficial interest
to a person who is required or permitted to take delivery thereof in the form of
an Unrestricted Global Security. Upon receipt by the Trustee of written
instructions, or such other form of instructions as is customary for the
Depositary, from the Depositary or its nominee on behalf of any person having a
beneficial interest in a Restricted Global Security and the following additional
information and documents in such form as is customary for the Depositary from
the Depositary or its nominee on behalf of the person having such beneficial
interest in the Restricted Global Security (all of which may be submitted by
facsimile or electronically):

               (i)      if such beneficial interest is being transferred
     pursuant to an effective registration statement under the Securities Act, a
     certification to that effect from the Holder (in substantially the form set
     forth in the Transfer Certificate); or

               (ii)     if such beneficial interest is being transferred
     pursuant to an exemption from the registration requirements of the
     Securities Act in accordance with Rule 144, a certification to that effect
     from the Holder (in substantially the form set forth in the Transfer
     Certificate) and, if the Company or the Trustee so requests, a customary
     Opinion of Counsel, certificates and other information reasonably
     acceptable to the Company and the Trustee to the effect that such transfer
     does not require registration under the Securities Act,

the Trustee, as the Registrar, shall reduce or cause to be reduced the aggregate
principal amount of the Restricted Global Security by the appropriate principal
amount and shall increase or cause to be increased the aggregate principal
amount of the Unrestricted Global Security by a like principal amount. Such
transfer shall otherwise be effected in accordance with the Applicable
Procedures. If no Unrestricted Global Security is then outstanding, the Company
shall execute and the Trustee shall, upon receipt of a Company Order (which the
Company agrees to deliver promptly), authenticate and deliver an Unrestricted
Global Security.

          (d)  TRANSFER OF A BENEFICIAL INTEREST IN AN UNRESTRICTED GLOBAL
SECURITY FOR A BENEFICIAL INTEREST IN A RESTRICTED GLOBAL SECURITY. Any person
having a beneficial interest in an Unrestricted Global Security may upon
request, subject to the Applicable Procedures, transfer such beneficial interest
to a person who is required or permitted to take delivery thereof in the form of
a Restricted Global Security (it being understood that only QIBs may own
beneficial interests in Restricted Global Securities). Upon receipt by the
Trustee of written instructions, or such other form of instructions as is
customary for the Depositary, from the Depository or its nominee on behalf of
any person having a beneficial interest in an Unrestricted Global Security and
the following additional information and documents in such form as is customary
for the Depositary, from the Depositary or its nominee on behalf of the person
having such beneficial

                                       20
<Page>

interest in the Unrestricted Global Security (all of which may be submitted by
facsimile or electronically): a certification from the Holder (in substantially
the form set forth in the Transfer Certificate) to the effect that such
beneficial interest is being transferred to a person that the transferor
reasonably believes is a QIB in accordance with Rule 144A. The Trustee, as the
Registrar, shall reduce or cause to be reduced the aggregate principal amount of
the Unrestricted Global Security by the appropriate principal amount and shall
increase or cause to be increased the aggregate principal amount of the
Restricted Global Security by a like principal amount. Such transfer shall
otherwise be effected in accordance with the Applicable Procedures. If no
Restricted Global Security is then outstanding, the Company shall execute and
the Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver a Restricted Global Security.

          (e)  TRANSFERS OF CERTIFICATED SECURITIES FOR BENEFICIAL INTEREST IN
GLOBAL SECURITIES. In the event that Certificated Securities are issued in
exchange for beneficial interests in Global Securities and, thereafter, the
events or conditions specified in Section 2.12(a)(i) which required such
exchange shall cease to exist, the Company shall mail notice to the Trustee and
to the Holders stating that Holders may exchange Certificated Securities or
interests in Global Securities by complying with the procedures set forth in
this Indenture and briefly describing such procedures and the events or
circumstances requiring that such notice be given. Thereafter, if Certificated
Securities are presented by a Holder to a Registrar with a request:

          (x)  to register the transfer of such Certificated Securities to a
     person who will take delivery thereof in the form of a beneficial interest
     in a Global Security, which request shall specify whether such Global
     Security will be a Restricted Global Security or an Unrestricted Global
     Security, or

          (y)  to exchange such Certificated Securities for an equal principal
     amount of beneficial interests in a Global Security, which beneficial
     interests will be owned by the Holder transferring such Certificated
     Securities (provided that in the case of such an exchange, Restricted
     Certificated Securities may be exchanged only for Restricted Global
     Securities and Unrestricted Certificated Securities may be exchanged only
     for Unrestricted Global Securities), the Registrar shall register the
     transfer or make the exchange as requested by canceling such Certificated
     Security and causing, or directing the Registrar to cause, the aggregate
     principal amount of the applicable Global Security to be increased
     accordingly and, if no such Global Security is then outstanding, the
     Company shall issue and the Trustee shall, upon receipt of a Company Order
     (which the Company agrees to deliver promptly) authenticate and deliver a
     new Global Security;

PROVIDED, HOWEVER, that the Certificated Securities presented or surrendered for
registration of transfer or exchange:

                        (1) shall be duly endorsed or accompanied by a written
          instrument of transfer in accordance with the proviso to Section 2.6;

                        (2) in the case of a Restricted Certificated Security to
          be transferred for a beneficial interest in an Unrestricted Global
          Security, such

                                       21
<Page>

          request shall be accompanied by the following additional information
          and documents, as applicable:

                                (i)     if such Restricted Certificated Security
                        is being transferred pursuant to an effective
                        registration statement under the Securities Act, a
                        certification to that effect from such Holder (in
                        substantially the form set forth in the Transfer
                        Certificate); or

                                (ii)    if such Restricted Certificated Security
                        is being transferred pursuant to an exemption from the
                        registration requirements of the Securities Act in
                        accordance with Rule 144, a certification to that effect
                        from such Holder (in substantially the form set forth in
                        the Transfer Certificate) and, if the Company or the
                        Registrar so requests, a customary Opinion of Counsel,
                        certificates and other information reasonably acceptable
                        to the Company and the Trustee to the effect that such
                        transfer does not require registration under of the
                        Securities Act;

                        (3) in the case of a Restricted Certificated Security to
          be transferred or exchanged for a beneficial interest in a Restricted
          Global Security, such request shall be accompanied by a certification
          from such Holder (in substantially the form set forth in the Transfer
          Certificate) to the effect that such Restricted Certificated Security
          is being transferred to a person the Holder reasonably believes is a
          QIB (which, in the case of an exchange, shall be such Holder) in
          accordance with Rule 144A;

                        (4) in the case of an Unrestricted Certificated Security
          to be transferred or exchanged for a beneficial interest in an
          Unrestricted Global Security, such request need not be accompanied by
          any additional information or documents; and

                        (5) in the case of an Unrestricted Certificated Security
          to be transferred or exchanged for a beneficial interest in a
          Restricted Global Security, such request shall be accompanied by a
          certification from such Holder (in substantially, the form set forth
          in the Transfer Certificate) to the effect that such Unrestricted
          Certificated Security is being transferred to a person the Holder
          reasonably believes is a QIB (which, in the case of an exchange, shall
          be such Holder) in accordance with Rule 144A.

          (f)  LEGENDS.

                        (1) Except as permitted by the following paragraphs (2),
          (3) and (4), each Global Security and Certificated Security (and all
          Securities issued in exchange therefor or upon registration of
          transfer or replacement thereof) shall bear a legend in substantially
          the form called for by footnote 2 to Exhibit A attached hereto (each a
          "TRANSFER RESTRICTED SECURITY"), for so long as it is required by this
          Indenture to bear such legend. Each Transfer Restricted Security

                                       22
<Page>

          shall have attached thereto a certificate (a "TRANSFER CERTIFICATE")
          in substantially the form called for by footnote 4 to Exhibit A
          attached hereto.

                        (2) Upon any sale or transfer of a Transfer Restricted
          Security (x) after the expiration of the holding period applicable to
          sales of the Securities under Rule 144(k) of the Securities Act; (y)
          pursuant to Rule 144 or (z) pursuant to an effective registration
          statement under the Securities Act:

                                (i)     in the case of any Restricted
                        Certificated Security, any Registrar shall permit the
                        Holder thereof to exchange such Restricted Certificated
                        Security for an Unrestricted Certificated Security, or
                        (under the circumstances described in Section 2.12(e))
                        to transfer such Restricted Certificated Security to a
                        transferee who shall take such Security in the form of a
                        beneficial interest in an Unrestricted Global Security,
                        and in each case shall rescind any restriction on the
                        transfer of such Security; PROVIDED, HOWEVER, that the
                        Holder of such Restricted Certificated Security shall,
                        in connection with such exchange or transfer, comply
                        with the other applicable provisions of this Section
                        2.12; and

                                (ii)    in the case of any beneficial interest
                        in a Restricted Global Security, the Trustee shall
                        permit the beneficial owner thereof to transfer such
                        beneficial interest to a transferee who shall take such
                        interest in the form of a beneficial interest in an
                        Unrestricted Global Security and shall rescind any
                        restriction on transfer of such beneficial interest;
                        PROVIDED, that such Unrestricted Global Security shall
                        continue to be subject to the provisions of Section
                        2.12(a)(ii); and PROVIDED, FURTHER, that the owner of
                        such beneficial interest shall, in connection with such
                        transfer, comply with the other applicable provisions of
                        this Section 2.12.

                        (3) Upon the exchange, registration of transfer or
          replacement of Securities not bearing the legend described in
          paragraph (1) above, the Company shall execute, and the Trustee shall
          authenticate and deliver Securities that do not bear such legend and
          that do not have a Transfer Certificate attached thereto.

                        (4) After the expiration of the holding period pursuant
          to Rule 144(k) of the Securities Act, the Company may with the consent
          of the Holder of a Restricted Global Security or a Restricted
          Certificated Security, remove any restriction of transfer on such
          Security, and the Company shall execute, and the Trustee shall
          authenticate and deliver Securities that do not bear such legend and
          that do not have a Transfer Certificate attached thereto.

                        (5) Until the expiration of the holding period
          applicable to sales of the Securities under Rule 144(k) of the
          Securities Act or a transfer pursuant to Rule 144 or pursuant to an
          effective registration statement under the

                                       23
<Page>

          Securities Act, the Ordinary Shares issued upon conversion of the
          Securities shall bear the legend in substantially the form called for
          by Exhibit C attached hereto.

          (g)  TRANSFERS TO THE COMPANY. Nothing contained in this Indenture or
in the Securities shall prohibit the sale or other transfer of any Securities
(including beneficial interests in Global Securities) to the Company or any of
its Subsidiaries, which Securities shall thereupon be cancelled in accordance
with Section 2.11.

          SECTION 2.13. CUSIP NUMBERS.

          The Company may issue the Securities with one or more "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

          SECTION 2.14. RANKING.

          The indebtedness of the Company arising under or in connection with
this Indenture and every outstanding Security issued under this Indenture from
time to time constitutes and will constitute a senior unsecured general
obligation of the Company, ranking equally with other existing and future senior
unsecured Indebtedness of the Company and ranking senior in right of payment to
any future Indebtedness of the Company that is expressly made subordinate to the
Securities by the terms of such Indebtedness.

          For purposes of this Section 2.14 only, "INDEBTEDNESS" means, without
duplication, the principal or face amount of:

          (a)  all obligations for borrowed money;

          (b)  all obligations evidenced by notes or other similar instruments;

          (c)  all obligations in respect of letters of credit or bankers
     acceptances or similar instruments (or reimbursement obligations with
     respect thereto);

          (d)  all obligations to pay the deferred purchase price of property or
     services, except trade accounts payable arising in the ordinary course of
     business;

          (e)  all obligations as lessee which are capitalized in accordance
     with generally accepted accounting principles; and

          (f)  all Indebtedness of others guaranteed by the Company or any of
     its Subsidiaries or for which the Company or any of its Subsidiaries is
     legally responsible or liable (whether by agreement to purchase
     indebtedness of, or to supply funds or to invest in, others).

                                   ARTICLE III

                                   REDEMPTION

          SECTION 3.1. THE COMPANY'S RIGHT TO REDEEM; NOTICE TO TRUSTEE.

          Prior to December 6, 2006, the Securities will not be redeemable at
the Company's option. Beginning on December 6, 2006, the Company, at its option,
may redeem the Securities in accordance with this Article III for cash at any
time as a whole, or from time to time in part, at a redemption price equal to
the principal amount of those Securities plus any accrued and unpaid interest
and Additional Amounts, if any, on those Securities to, but not including, the
Redemption Date (the "Redemption Price").

          In the event that the Company elects to redeem the Securities on a
date that is after any Regular Record Date but before the corresponding Interest
Payment Date, the Company shall be required to pay any accrued and unpaid
interest and Additional Amounts, if any, to the redeemed Securityholder and not
the Holder on the corresponding Interest Payment Date.

          If the Company elects to redeem Securities, it shall notify the
Trustee in writing of the Redemption Date, the principal amount of Securities to
be redeemed and the Redemption Price. The Company shall give this notice to the
Trustee by a Company Order at least 40 days before the Redemption Date (unless a
shorter notice shall be satisfactory to the Trustee).

          SECTION 3.2. SELECTION OF SECURITIES TO BE REDEEMED.

          If fewer than all of the outstanding Securities are to be redeemed,
unless the procedures of the Depositary provide otherwise, the Trustee shall
select the Securities to be redeemed by lot or on a pro rata basis. The Trustee
shall make the selection within five Business Days after it receives the notice
provided for in Section 3.1 from outstanding Securities not previously called
for redemption.

          Securities and portions of Securities that the Trustee selects shall
be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions
of this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of the Securities to be redeemed.

          Securities and portions of Securities that are to be redeemed are
convertible by the Holder until 5:00 p.m., New York City time, on the second
Business Day immediately preceding to the Redemption Date. If any Security
selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Security so selected, the
converted portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption. Securities which have been converted during a
selection of Securities to be redeemed may be treated by the Trustee as
outstanding for the purpose of such selection.

          SECTION 3.3. NOTICE OF REDEMPTION.

                                       25
<Page>

          At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail a notice of redemption by first-class mail, postage
prepaid, to each Holder of Securities to be redeemed.

          The notice of redemption shall identify the Securities to be redeemed
and shall state:

          (a)  the Redemption Date;

          (b)  the Redemption Price;

          (c)  the Conversion Price;

          (d)  the name and address of the Paying Agent and Conversion Agent;

          (e)  that Securities called for redemption may be converted at any
     time prior to 5:00 p.m., New York City time, on the second Business Day
     preceding the Redemption Date;

          (f)  that Holders who want to convert their Securities must satisfy
     the requirements set forth in Article XII;

          (g)  that Securities called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price;

          (h)  if fewer than all of the outstanding Securities are to be
     redeemed, the certificate numbers, if any, and principal amounts of the
     particular Securities to be redeemed;

          (i)  that, unless the Company defaults in making payment of such
     Redemption Price, interest and Additional Amounts, if any, on Securities
     called for redemption will cease to accrue on and after the Redemption
     Date;

          (j)  the CUSIP number(s) of the Securities; and

          (k)  any other information the Company wants to present.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense; PROVIDED,
HOWEVER, that the Company makes such request at least five Business Days (unless
a shorter period shall be satisfactory to the Trustee) prior to the date by
which such notice of redemption must be given to Holders in accordance with this
Section 3.3; PROVIDED, FURTHER, that the text of the notice of redemption shall
be prepared by the Company.

          SECTION 3.4. EFFECT OF NOTICE OF REDEMPTION.

          Once notice of redemption is given, Securities called for redemption
become due and payable on the Redemption Date and at the Redemption Price,
except for Securities which

                                       26
<Page>

are converted in accordance with the terms of this Indenture. Upon surrender to
the Paying Agent, such Securities shall be paid at the Redemption Price.

          SECTION 3.5. DEPOSIT OF REDEMPTION PRICE.

          Prior to 10:00 a.m., New York City time, on the applicable Redemption
Date, the Company shall deposit with the Paying Agent (or if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent,
shall segregate and hold in trust as provided in Section 2.4) an amount of cash
(in immediately available funds if deposited on the Redemption Date) sufficient
to pay the aggregate Redemption Price of all Securities or portions thereof
which are to be redeemed as of such Redemption Date other than Securities or
portions of Securities called for redemption which on or prior thereto have been
delivered by the Company to the Trustee for cancellation or have been converted.

          If the Paying Agent holds, in accordance with the terms hereof, at
10:00 a.m., New York City time, on the applicable Redemption Date, cash
sufficient to pay the Redemption Price of any Securities for which notice of
redemption is given, then, on such Redemption Date, such Securities will cease
to be outstanding and interest and Additional Amounts, if any, on such
Securities will cease to accrue, whether or not such Securities are delivered to
the Paying Agent, and the rights of the Holders in respect thereof shall
terminate (other than the right to receive the Redemption Price upon delivery of
such Securities).

          SECTION 3.6. SECURITIES REDEEMED IN PART.

          Any Certificated Security which is to be redeemed only in part shall
be surrendered at the office of the Paying Agent and the Company shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security,
without charge, a new Security or Securities, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to the unredeemed
portion of the Security surrendered.

          SECTION 3.7. REPAYMENT TO THE COMPANY.

          To the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 3.5 exceeds the aggregate Redemption Price of the
Securities or portions thereof which the Company is redeeming as of the
Redemption Date, then, promptly after the Redemption Date, the Paying Agent
shall return any such excess to the Company.

                                   ARTICLE IV

                            REPURCHASE OF SECURITIES
                            AT THE OPTION OF HOLDERS
                                ON SPECIFIC DATES

          SECTION 4.1. OPTIONAL PUT.

          (a)  Securities shall be repurchased by the Company at the option of
the Holder on December 6, 2007, December 1, 2010, December 1, 2012 and December
1, 2017 (each, a "REPURCHASE DATE"), at a repurchase price equal to the
principal amount of those

                                       27
<Page>

Securities plus accrued and unpaid interest and Additional Amounts, if any, to,
but not including, such Repurchase Date (the "REPURCHASE PRICE"), subject to
satisfaction by or on behalf of the Holder of the requirements set forth in
Section 4.1(c).

          (b)  No later than 20 days prior to each Repurchase Date, the Company
shall mail a written notice of the repurchase right by first class mail to the
Trustee and to each Holder (and to beneficial owners as required by applicable
law). The notice shall include a form of Repurchase Notice to be completed by
the Holder and shall briefly state, as applicable:

               (i)      the date by which the Repurchase Notice must be
     delivered to the Paying Agent in order for a Holder to exercise the
     repurchase right;

               (ii)     the Repurchase Date;

               (iii)    the Repurchase Price;

               (iv)     whether the Repurchase Price will be paid in cash or
     Ordinary Shares, or a combination thereof and, in the case of a
     combination, the percentage of each;

               (v)      if the Company elects to pay the Repurchase Price in
     Ordinary Shares or a combination of cash and Ordinary Shares, that the
     number of Ordinary Shares each Holder will receive will equal the portion
     of the Repurchase Price to be paid in Ordinary Shares divided by 97.5% of
     the Market Price of one Ordinary Share;

               (vi)     if the Company elects to pay the Repurchase Price in
     Ordinary Shares or a combination of cash and Ordinary Shares, the method of
     calculating the Market Price of the Ordinary Shares;

               (vii)    state that because the Market Price of one Ordinary
     Share will be determined prior to the Repurchase Date, Holders of the
     Securities will bear the market risk that the Ordinary Shares to be
     received will decline in value between the date such Market Price is
     determined and the Repurchase Date;

               (viii)   the name and address of the Paying Agent and the
     Conversion Agent;

               (ix)     the Conversion Rate and any adjustments thereto;

               (x)      that the Securities as to which a Repurchase Notice has
     been given may be converted if they are otherwise convertible pursuant to
     Article XII only if the Repurchase Notice has been withdrawn in accordance
     with the terms of this Indenture;

               (xi)     that the Securities must be surrendered to the Paying
     Agent to collect payment;

               (xii)    that the Repurchase Price for any Security as to which a
     Repurchase Notice has been duly given and not withdrawn will be paid
     promptly

                                       28
<Page>

     following the later of the Repurchase Date and the time of surrender of
     such Security as described in Section 4.1(b)(xi);

               (xiii)   the procedures the Holder must follow to exercise its
     put right under this Section 4.1;

               (xiv)    the conversion rights, if any, of the Securities;

               (xv)     the procedures for withdrawing a Repurchase Notice;

               (xvi)    that, unless the Company defaults in making payment of
     such Repurchase Price, interest and Additional Amounts, if any, on
     Securities surrendered for repurchase by the Company will cease to accrue
     on and after the Repurchase Date; and

               (xvii)   the CUSIP number(s) of the Securities.

          At the Company's request, the Trustee shall give the notice of
repurchase right in the Company's name and at the Company's expense; PROVIDED,
HOWEVER, that the Company makes such request at least five Business Days (unless
a shorter period shall be satisfactory to the Trustee) prior to the date by
which such notice of repurchase right must be given to the Holders in accordance
with this Section 4.1(b); PROVIDED, FURTHER, that the text of the notice of
repurchase right shall be prepared by the Company.

          (c)  A Holder may exercise its right specified in Section 4.1(a) upon
delivery of a written notice of repurchase (a "REPURCHASE NOTICE") to the Paying
Agent at any time during the period beginning at 9:00 a.m., New York City time,
on the date that is 20 Business Days preceding the relevant Repurchase Date
until 5:00 p.m., New York City time, on the Business Day immediately preceding
such Repurchase Date, stating:

               (i)      the certificate number of the Security which the Holder
     will deliver to be repurchased or the appropriate Depositary procedures if
     Certificated Securities have not been issued;

               (ii)     the portion of the principal amount of the Security
     which the Holder will deliver to be repurchased, which portion must be in
     principal amounts of $1,000 or an integral multiple of $1,000;

               (iii)    that such Security shall be repurchased by the Company
     as of the Repurchase Date pursuant to the terms and conditions specified in
     Section 6 of the Securities and in this Indenture; and

               (iv)     in the event the Company elects, pursuant to
     Section 4.2(b), to pay the Repurchase Price, in whole or in part, in
     Ordinary Shares but such portion of the Repurchase Price shall ultimately
     be paid to such Holder entirely in cash because any of the conditions to
     payment of the Repurchase Price in Ordinary Shares is not satisfied prior
     to 5:00 p.m., New York City time, on the Business Day immediately preceding
     the relevant Repurchase Date, as set forth in Section 4.2(b), whether such
     Holder elects to (A) withdraw such Repurchase Notice as to some or all of
     the Securities to which such

                                       29
<Page>

     Repurchase Notice relates (stating the principal amount and certificate
     numbers, if any, of the Securities as to which such withdrawal shall
     relate), or (B) receive cash in respect of the entire Repurchase Price for
     all Securities (or portions thereof) to which such Repurchase Notice
     relates.

          The delivery of such Security to the Paying Agent with, or at any time
after delivery of, the Repurchase Notice (together with all necessary
endorsements) at the offices of the Paying Agent shall be a condition to the
receipt by the Holder of the Repurchase Price therefor; PROVIDED, HOWEVER, that
such Repurchase Price shall be so paid pursuant to this Section 4.1 only if the
Security so delivered to the Paying Agent shall conform in all respects to the
description thereof in the related Repurchase Notice.

          If a Holder, in such Holder's Repurchase Notice and in any written
notice of withdrawal delivered by such Holder pursuant to the terms of Section
4.3, fails to indicate such Holder's choice with respect to the election set
forth in Section 4.1(c)(iv), such Holder shall be deemed to have elected to
receive cash in respect of the entire Repurchase Price for all Securities
subject to such Repurchase Notice in the circumstances set forth in such Section
4.1(c)(iv).

          The Company shall repurchase from the Holder thereof, pursuant to this
Section 4.1, a portion of a Security, so long as the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the repurchase of all of a Security also apply to the
repurchase of such portion of such Security.

          Any repurchase by the Company contemplated pursuant to the provisions
of this Section 4.1 shall be consummated by the delivery of the consideration to
be received by the Holder promptly following the later of the Repurchase Date
and the time of delivery of the Security.

          Notwithstanding anything contained herein to the contrary, any Holder
delivering to the Paying Agent the Repurchase Notice contemplated by this
Section 4.1(c) shall have the right to withdraw such Repurchase Notice at any
applicable time prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Repurchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 4.3.

          The Paying Agent shall promptly notify the Company of the receipt by
it of any Repurchase Notice or written notice of withdrawal thereof.

          SECTION 4.2. THE COMPANY'S RIGHT TO ELECT MANNER OF PAYMENT OF
REPURCHASE PRICE.

          (a)  The Securities to be repurchased on any Repurchase Date pursuant
to Section 4.1(a) may be paid for at the election of the Company, in cash or
Ordinary Shares, or in any combination of cash and Ordinary Shares, subject to
the conditions set forth in Section 4.2(b). The Company shall designate, in the
notice of repurchase right delivered pursuant to Section 4.1(b), whether the
Company will repurchase the Securities for cash or Ordinary Shares, or, if a
combination thereof, the percentages of the Repurchase Price in respect of which
it will pay in cash or Ordinary Shares; PROVIDED that the Company will pay cash
for fractional interests in an Ordinary Share. For purposes of determining the
existence of potential fractional interests,

                                       30
<Page>

all Securities subject to repurchase by the Company held by a Holder shall be
considered together (no matter how many separate certificates are to be
presented). Each Holder whose Securities are repurchased pursuant to Section 4.1
shall receive the same percentage of cash or Ordinary Shares in payment of the
Repurchase Price for such Securities, except as provided in this Section 4.2(a)
with regard to the payment of cash in lieu of fractional shares of an Ordinary
Share. The Company may not change its election with respect to the consideration
(or components or percentages of components thereof) to be paid once the Company
has given its notice of repurchase right to Holders except in the event of a
failure to satisfy, prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Repurchase Date, any condition to the payment of the
Repurchase Price in whole or in part, in Ordinary Shares.

          (b)  If the Company elects to pay all or a portion of the Repurchase
Price of Securities in respect of which a Repurchase Notice pursuant to Section
4.1(c) has been given in Ordinary Shares, the number of Ordinary Shares to be
issued shall be equal to (i) the portion of the Repurchase Price to be paid in
Ordinary Shares divided by (ii) 97.5% of the Market Price of one Ordinary Share,
subject to satisfaction of the conditions set forth in the second succeeding
paragraph.

          The Company will not issue any fraction of an Ordinary Share in
payment of the Repurchase Price. Instead, the Company will make a cash payment
(calculated to the nearest cent) equal to such fraction multiplied by the Market
Price of one Ordinary Share. If a Holder elects to have more than one Security
purchased, the number of Ordinary Shares shall be based on the aggregate amount
of Securities to be purchased.

          The Company's right to exercise its election to repurchase Securities
through the issuance of Ordinary Shares shall be conditioned upon:

               (i)      the registration of such Ordinary Shares under the
     Securities Act and the Exchange Act, in each case, if required;

               (ii)     any qualification or registration of such Ordinary
     Shares under applicable state securities laws, if necessary, or the
     availability of an exemption from such qualification and registration;

               (iii)    the listing of such Ordinary Shares on a United States
     national securities exchange or the quotation of such Ordinary Shares in an
     inter-dealer quotation system of any registered United States national
     securities association; and

               (iv)     the receipt by the Trustee of an Officers' Certificate
     stating (A) that the terms of the issuance of the Ordinary Shares are in
     conformity with this Indenture; (B) that the Ordinary Shares to be issued
     in payment of the Repurchase Price in respect of Securities have been duly
     authorized and, when issued and delivered pursuant to the terms of this
     Indenture in payment of the Repurchase Price in respect of Securities, will
     be validly issued, fully paid, non-assessable and free from preemptive
     rights; (C) that the conditions above and the condition set forth in the
     second succeeding sentence have been satisfied; and (D) the number of
     Ordinary Shares to be issued for each $1,000 principal amount of Securities
     and the Sale Price of an Ordinary Share on

                                       31
<Page>

     each Trading Day during the period commencing on the first Trading Day of
     the period during which the Market Price is calculated and ending on the
     Trading Day immediately preceding the Repurchase Date; and

               (v)      the receipt by the Trustee of an Opinion of Counsel
     stating that (A) the terms of the issuance of the Ordinary Shares are in
     conformity with this Indenture; (B) the Ordinary Shares to be issued in
     payment of the Repurchase Price in respect of Securities have been duly
     authorized, and when issued and delivered pursuant to the terms of this
     Indenture in payment of the Repurchase Price in respect of Securities, will
     be validly issued, fully paid and non-assessable and, to the best of such
     counsel's knowledge, free from preemptive rights; and (C) the conditions in
     clauses (i) through (iii) above have been satisfied.

          If the foregoing conditions are not satisfied with respect to a Holder
or Holders prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Repurchase Date, and the Company has elected to
repurchase the Securities pursuant to this Section 4.2 through the issuance of
Ordinary Shares, the Company shall pay the entire Repurchase Price of the
Securities of such Holder or Holders in cash.

          Upon determination of the actual number of Ordinary Shares to be
issued upon repurchase of Securities, the Company shall be required to
disseminate a press release through Dow Jones & Company, Inc. or Bloomberg
Business News containing this information or publish the information on the
Company's web site or through such other public medium as the Company may use at
that time.

          (c)  COVENANTS OF THE COMPANY. All Ordinary Shares delivered upon
repurchase of the Securities shall be newly issued shares, shall be duly
authorized, validly issued, fully paid and nonassessable, and shall be free from
preemptive rights and free of any lien or adverse claim.

          (d)  TAXES. If a Holder of a repurchased Security is paid in Ordinary
Shares, the Company shall pay any documentary, stamp or similar issue or
transfer tax due on such issue of Ordinary Shares. However, the Holder shall pay
any such tax which is due because the Holder requests the Ordinary Shares to be
issued in a name other than the Holder's name. The Paying Agent may refuse to
deliver the certificates representing the Ordinary Shares being issued in a name
other than the Holder's name until the Paying Agent receives a sum sufficient to
pay any tax which will be due because the Ordinary Shares are to be issued in a
name other than the Holder's name. Nothing contained herein shall preclude any
income tax withholding required by law or regulations.

          SECTION 4.3. EFFECT OF REPURCHASE NOTICE.

          Upon receipt by the Paying Agent of the Repurchase Notice specified in
Section 4.1(c), the Holder of the Security in respect of which such Repurchase
Notice was given shall (unless such Repurchase Notice is withdrawn as specified
in the following paragraph) thereafter be entitled to receive solely the
Repurchase Price with respect to such Security. Such Repurchase Price shall be
paid to such Holder, subject to receipts of cash and/or securities by the

                                       32
<Page>

Paying Agent, promptly following the later of (a) the Repurchase Date with
respect to such Security (provided the conditions in Section 4.1(c) have been
satisfied) and (b) the time of delivery of such Security to the Paying Agent by
the Holder thereof in the manner required by Section 4.1(c). Securities in
respect of which a Repurchase Notice has been given by the Holder thereof may
not be converted pursuant to Article XII on or after the date of the delivery of
such Repurchase Notice unless such Repurchase Notice has first been validly
withdrawn as specified in the following paragraph.

          A Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent in accordance with the
Repurchase Notice at any time prior to 5:00 p.m., New York City time, on the
Business Day immediately preceding the Repurchase Date, specifying:

          (a)  the certificate number, if any, of the Security in respect of
     which such notice of withdrawal is being submitted;

          (b)  the principal amount of the Security with respect to which such
     notice of withdrawal is being submitted; and

          (c)  the principal amount, if any, of such Security which remains
     subject to the original Repurchase Notice and which has been or will be
     delivered for repurchase by the Company.

          SECTION 4.4. DEPOSIT OF REPURCHASE PRICE.

          Prior to 10:00 a.m., New York City time, on the applicable Repurchase
Date, the Company shall deposit with the Paying Agent (or if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent,
shall segregate and hold in trust as provided in Section 2.4) an amount of cash
(in immediately available funds if deposited on such Business Day) and/or
Ordinary Shares, if permitted hereunder, sufficient to pay the aggregate
Repurchase Price of all the Securities or portions thereof which are to be
repurchased as of such Repurchase Date.

          If the Paying Agent holds, in accordance with the terms hereof, at
10:00 a.m., New York City time, on the applicable Repurchase Date, cash and/or
Ordinary Shares, if permitted hereunder, sufficient to pay the Repurchase Price
of any Securities for which a Repurchase Notice has been tendered and not
withdrawn pursuant to Section 4.3, then, on such Repurchase Date, such
Securities will cease to be outstanding and interest and Additional Amounts, if
any, on such Securities will cease to accrue, whether or not such Securities are
delivered to the Paying Agent, and the rights of the Holders in respect thereof
shall terminate (other than the right to receive the Repurchase Price upon
delivery of such Securities).

          As soon as practicable on and after the Repurchase Date, the Company
shall deliver to each Holder entitled to receive Ordinary Shares through the
Paying Agent, a certificate for the number of full Ordinary Shares issuable in
payment of the Repurchase Price and cash in lieu of any fractional interests.
The person in whose name the certificate for the Ordinary Shares is registered
shall be treated as a holder of record of Ordinary Shares on the Business Day

                                       33
<Page>

following the Repurchase Date. No payment or adjustment will be made for
dividends on the Ordinary Shares the record date for which occurred on or prior
to the Repurchase Date.

          SECTION 4.5. SECURITIES REPURCHASED IN PART.

          Any Certificated Security which is to be repurchased only in part
shall be surrendered at the office of the Paying Agent (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Security, without charge, a new Security or Securities, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in exchange for, the portion of the principal amount of the Security so
surrendered which is not repurchased.

          SECTION 4.6. COVENANT TO COMPLY WITH SECURITIES LAWS UPON REPURCHASE
OF SECURITIES.

          When complying with the provisions of Section 4.1 hereof (provided
that such offer or purchase constitutes an "issuer tender offer" for purposes of
Rule 13e-4 (which term, as used herein, includes any successor provision
thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

          (a)  comply with Rule 13e-4 and Rule 14e-1 (or any successor
     provision) under the Exchange Act;

          (b)  file the related Schedule TO (or any successor schedule, form or
     report) under the Exchange Act; and

          (c)  otherwise comply with all Federal and state securities laws so as
     to permit the rights and obligations under Article IV to be exercised in
     the time and in the manner specified therein.

          SECTION 4.7. REPAYMENT TO THE COMPANY.

          To the extent that the aggregate amount of cash or Ordinary Shares
deposited by the Company pursuant to Section 4.4 exceeds the aggregate
Repurchase Price of the Securities or portions thereof which the Company is
obligated to repurchase as of the Repurchase Date, then, promptly after the
Repurchase Date, the Paying Agent shall return any such excess to the Company.

                                    ARTICLE V

                       REPURCHASE AT THE OPTION OF HOLDERS
                            UPON A CHANGE OF CONTROL

          SECTION 5.1. CHANGE OF CONTROL PUT.

                                       34
<Page>

          (a)  If a Change of Control occurs, the Securities not previously
repurchased by the Company shall be repurchased by the Company, at the option of
the Holder thereof, at a repurchase price equal to the principal amount of those
Securities plus accrued and unpaid interest and Additional Amounts, if any, to,
but not including, the change of control repurchase date (the "CHANGE OF CONTROL
REPURCHASE PRICE"), subject to satisfaction by or on behalf of the Holder of the
requirements set forth in Section 5.1(c). The change of control repurchase date
is the 30th day after the date of a notice of Change of Control delivered by the
Company (the "CHANGE OF CONTROL REPURCHASE DATE").

          (b)  No later than 30 days after the occurrence of a Change of
Control, the Company shall mail a written notice of the Change of Control by
first class mail to the Trustee and to each Holder (and to beneficial owners as
required by applicable law). The notice shall include a form of Change of
Control Repurchase Notice to be completed by the Holder and shall briefly state,
as applicable:

               (i)      the events causing a Change of Control and the date of
     such Change of Control;

               (ii)     that the Holder has a right to require us to repurchase
     the Holder's Securities;

               (iii)    the date by which the Change of Control Repurchase
     Notice must be delivered to the Paying Agent in order for a Holder to
     exercise the change of control repurchase right;

               (iv)     the Change of Control Repurchase Date;

               (v)      the Change of Control Repurchase Price;

               (vi)     whether the Change of Control Repurchase Price will be
     paid in cash or shares of Applicable Stock, or a combination thereof and,
     in the case of a combination, the percentage of each;

               (vii)    if the Company elects to pay the Change of Control
     Repurchase Price in shares of Applicable Stock or a combination of cash and
     shares of Applicable Stock, that the number of shares of Applicable Stock
     each Holder will receive will equal the portion of the Change of Control
     Repurchase Price to be paid in shares of Applicable Stock divided by 97.5%
     of the Market Price of one share of Applicable Stock;

               (viii)   if the Company elects to pay the Change of Control
     Repurchase Price in shares of Applicable Stock or a combination of cash and
     shares of Applicable Stock, the method of calculating the Market Price of
     the shares of Applicable Stock;

               (ix)     state that because the Market Price of one share of
     Applicable Stock will be determined prior to the Change of Control
     Repurchase Date, Holders of the Securities will bear the market risk that
     the shares of Applicable Stock to be received will decline in value between
     the date such Market Price is determined and the Change of Control
     Repurchase Date;

                                       35
<Page>

               (x)      the name and address of the Paying Agent and the
     Conversion Agent;

               (xi)     the Conversion Rate and any adjustments thereto;

               (xii)    that the Securities as to which a Change of Control
     Repurchase Notice has been given may be converted if they are otherwise
     convertible pursuant to Article XII only if the Change of Control
     Repurchase Notice has been withdrawn in accordance with the terms of this
     Indenture;

               (xiii)   that the Securities must be surrendered to the Paying
     Agent to collect payment;

               (xiv)    that the Change of Control Repurchase Price for any
     Security as to which a Change of Control Repurchase Notice has been duly
     given and not withdrawn will be paid promptly following the later of the
     Change of Control Repurchase Date and the time of surrender of such
     Security as described in 5.1(b)(xii);

               (xv)     the procedures the Holder must follow to exercise its
     put right under this Section 5.1;

               (xvi)    the conversion rights, if any, of the Securities;

               (xvii)   the procedures for withdrawing a Change of Control
     Repurchase Notice;

               (xviii)  that, unless the Company defaults in making payment of
     such Change of Control Repurchase Price, interest and Additional Amounts,
     if any, on Securities surrendered for repurchase by the Company will cease
     to accrue on and after the Change of Control Repurchase Date; and

               (xix)    the CUSIP number(s) of the Securities.

          At the Company's request, the Trustee shall give the notice of change
of control in the Company's name and at the Company's expense; PROVIDED,
HOWEVER, that the Company makes such request at least five Business Days (unless
a shorter period shall be satisfactory to the Trustee) prior to the date by
which such notice of change of control must be given to the Holders in
accordance with this Section 5.1(b); PROVIDED, FURTHER, that the text of the
notice of change of control shall be prepared by the Company.

          (c)  A Holder may exercise its right specified in Section 5.1(a) upon
delivery of a written notice of repurchase (a "CHANGE OF CONTROL REPURCHASE
NOTICE") to the Paying Agent at any time prior to 5:00 p.m., New York City time,
on the Business Day immediately preceding the Change of Control Repurchase Date,
stating:

               (i)      the certificate number of the Security which the Holder
     will deliver to be repurchased or the appropriate depositary procedures if
     Certificated Securities have not been issued;

                                       36
<Page>

               (ii)     the portion of the principal amount of the Security
     which the Holder will deliver to be repurchased, which portion must be
     $1,000 or an integral multiple of $1,000;

               (iii)    that such Security shall be repurchased as of the Change
     of Control Repurchase Date pursuant to the terms and conditions specified
     in Section 6 of the Securities and in this Indenture; and

               (iv)     in the event the Company elects, pursuant to
     Section 5.2(b), to pay the Change of Control Repurchase Price, in whole or
     in part, in shares of Applicable Stock but such portion of the Change of
     Control Repurchase Price shall ultimately be paid to such Holder entirely
     in cash because any of the conditions to payment of the Change of Control
     Repurchase Price in shares of Applicable Stock is not satisfied prior to
     5:00 p.m., New York City time, on the Business Day immediately preceding
     the Change of Control Repurchase Date, as set forth in Section 5.2(b),
     whether such Holder elects to (A) withdraw such Change of Control
     Repurchase Notice as to some or all of the Securities to which such Change
     of Control Repurchase Notice relates (stating the principal amount and
     certificate numbers, if any, of the Securities as to which such withdrawal
     shall relate), or (B) receive cash in respect of the entire Change of
     Control Repurchase Price for all Securities (or portions thereof) to which
     such Change of Control Repurchase Notice relates.

          The delivery of such Security to the Paying Agent with, or at any time
after delivery of, the Change of Control Repurchase Notice (together with all
necessary endorsements) at the offices of the Paying Agent shall be a condition
to the receipt by the Holder of the Change of Control Repurchase Price therefor;
PROVIDED, HOWEVER, that such Change of Control Repurchase Price shall be so paid
pursuant to this Section 5.1 only if the Security so delivered to the Paying
Agent shall conform in all respects to the description thereof set forth in the
related Change of Control Repurchase Notice.

          If a Holder, in such Holder's Change of Control Repurchase Notice and
in any written notice of withdrawal delivered by such Holder pursuant to the
terms of Section 5.3, fails to indicate such Holder's choice with respect to the
election set forth in Section 5.1(c)(iv), such Holder shall be deemed to have
elected to receive cash in respect of the entire Change of Control Repurchase
Price for all Securities subject to such Change of Control Repurchase Notice in
the circumstances set forth in such Section 5.1(c)(iv).

          The Company shall repurchase from the Holder thereof, pursuant to this
Section 5.1, a portion of a Security, so long as the principal amount of such
portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the repurchase of all of a Security also apply to the
repurchase of such portion of such Security.

          Any repurchase by the Company contemplated pursuant to the provisions
of this Section 5.1 shall be consummated by the delivery of the consideration to
be received by the Holder promptly following the later of the Change of Control
Repurchase Date and the time of delivery of the Security.

                                       37
<Page>

          Notwithstanding anything contained herein to the contrary, any Holder
delivering to the Paying Agent the Change of Control Repurchase Notice
contemplated by this Section 5.1(c) shall have the right to withdraw such Change
of Control Repurchase Notice at any time prior to 5:00 p.m., New York City time,
on the Business Day immediately preceding the Change of Control Repurchase Date
by delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 5.3.

          The Paying Agent shall promptly notify the Company of the receipt by
it of any Change of Control Repurchase Notice or written notice of withdrawal
thereof.

          SECTION 5.2. THE COMPANY'S RIGHT TO ELECT MANNER OF PAYMENT OF CHANGE
OF CONTROL REPURCHASE PRICE.

          (a)  The Securities to be repurchased on any Change of Control
Repurchase Date pursuant to Section 5.1(a) may be paid for at the election of
the Company, in cash or shares of Applicable Stock, or in any combination of
cash and shares of Applicable Stock, subject to the conditions set forth in
Section 5.2(b). The Company shall designate, in the notice of change of control
delivered pursuant to Section 5.1(b), whether the Company will repurchase the
Securities for cash or shares of Applicable Stock, or, if a combination thereof,
the percentages of the Change of Control Repurchase Price in respect of which it
will pay in cash or shares of Applicable Stock; PROVIDED that the Company will
pay cash for fractional interests in shares of Applicable Stock. For purposes of
determining the existence of potential fractional interests, all Securities
subject to repurchase by the Company held by a Holder shall be considered
together (no matter how many separate certificates are to be presented). Each
Holder whose Securities are repurchased pursuant to Section 5.1 shall receive
the same percentage of cash or shares of Applicable Stock in payment of the
Change of Control Repurchase Price for such Securities, except as provided in
this Section 5.2(a) with regard to the payment of cash in lieu of fractional
shares of Applicable Stock. The Company may not change its election with respect
to the consideration (or components or percentages of components thereof) to be
paid once the Company has given its notice of change of control to Holders
except in the event of a failure to satisfy, prior to 5:00 p.m., New York City
time, on the Business Day immediately preceding the Change of Control Repurchase
Date, any condition to the payment of the Change of Control Repurchase Price in
whole or in part, in shares of Applicable Stock.

          (b)  If the Company elects to pay all or a portion of the Change of
Control Repurchase Price of Securities in respect of which a Change of Control
Repurchase Notice pursuant to Section 5.1(c) has been given in Applicable Stock,
the number of shares of Applicable Stock to be issued shall be equal to (i) the
portion of the Change of Control Repurchase Price to be paid in shares of
Applicable Stock divided by (ii) 97.5% of the Market Price of one share of
Applicable Stock, subject to satisfaction of the conditions set forth in the
second succeeding paragraph.

          The Company will not issue any fraction of a share of Applicable Stock
in payment of the Change of Control Repurchase Price. Instead, the Company will
make a cash payment (calculated to the nearest cent) equal to such fraction
multiplied by the Market Price of one share of Applicable Stock. If a Holder
elects to have more than one Security purchased, the

                                       38
<Page>

number of shares of Applicable Stock shall be based on the aggregate amount of
Securities to be purchased.

          The Company's right to exercise its election to repurchase Securities
through the issuance of shares of Applicable Stock shall be conditioned upon:

               (i)      the registration of such shares of Applicable Stock
     under the Securities Act and the Exchange Act, in each case, if required;

               (ii)     any qualification or registration of such shares of
     Applicable Stock under applicable state securities laws, if necessary, or
     the availability of an exemption from such qualification and registration;

               (iii)    the listing of such shares of Applicable Stock on a
     United States national securities exchange or the quotation of such shares
     of Applicable Stock in an inter-dealer quotation system of any registered
     United States national securities association; and

               (iv)     the receipt by the Trustee of an Officers' Certificate
     stating (A) that the terms of the issuance of the shares of Applicable
     Stock are in conformity with this Indenture; (B) that the shares of
     Applicable Stock to be issued in payment of the Change of Control
     Repurchase Price in respect of Securities have been duly authorized and,
     when issued and delivered pursuant to the terms of this Indenture in
     payment of the Change of Control Repurchase Price in respect of Securities,
     will be validly issued, fully paid, non-assessable and free from preemptive
     rights; (C) that the conditions above and the condition set forth in the
     second succeeding sentence have been satisfied; and (D) the number of
     shares of Applicable Stock to be issued for each $1,000 principal amount of
     Securities and the Sale Price of a share of Applicable Stock on each
     Trading Day during the period commencing on the first Trading Day of the
     period during which the Market Price is calculated and ending on the
     Trading Day immediately preceding the Change of Control Repurchase Date;
     and

               (v)      the receipt by the Trustee of an Opinion of Counsel
     stating that (A) the terms of the issuance of the shares of Applicable
     Stock are in conformity with this Indenture; (B) the shares of Applicable
     Stock to be issued by the Company in payment of the Change of Control
     Repurchase Price in respect of Securities have been duly authorized, and
     when issued and delivered pursuant to the terms of this Indenture in
     payment of the Change of Control Repurchase Price in respect of Securities,
     will be validly issued, fully paid and non-assessable and, to the best of
     such counsel's knowledge, free from preemptive rights; and (C) the
     conditions in clauses (i) through (iii) above have been satisfied.

          If the foregoing conditions are not satisfied with respect to a Holder
or Holders prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Change of Control Repurchase Date, and the Company has
elected to repurchase the Securities pursuant to this Section 5.2 through the
issuance of shares of Applicable Stock, the Company shall pay the entire Change
of Control Repurchase Price of the Securities of such Holder or Holders in cash.

                                       39
<Page>

          Upon determination of the actual number of shares of Applicable Stock
to be issued upon repurchase of Securities, the Company shall be required to
disseminate a press release through Dow Jones & Company, Inc. or Bloomberg
Business News containing this information or publish the information on the
Company's web site or through such other public medium as the Company may use at
that time.

          (c)  COVENANTS OF THE COMPANY. All shares of Applicable Stock
delivered upon repurchase of the Securities shall be newly issued shares, shall
be duly authorized, validly issued, fully paid and nonassessable, and shall be
free from preemptive rights and free of any lien or adverse claim.

          (d)  TAXES. If a Holder of a repurchased Security is paid in shares of
Applicable Stock, the Company shall pay any documentary, stamp or similar issue
or transfer tax due on such issue of Applicable Stock. However, the Holder shall
pay any such tax which is due because the Holder requests the Applicable Stock
to be issued in a name other than the Holder's name. The Paying Agent may refuse
to deliver the certificates representing the shares of Applicable Stock being
issued in a name other than the Holder's name until the Paying Agent receives a
sum sufficient to pay any tax which will be due because the shares of Applicable
Stock are to be issued in a name other than the Holder's name. Nothing contained
herein shall preclude any income tax withholding required by law or regulations.

          SECTION 5.3. EFFECT OF CHANGE OF CONTROL REPURCHASE NOTICE.

          Upon receipt by the Paying Agent of the Change of Control Repurchase
Notice specified in Section 5.1(c), the Holder of the Security in respect of
which such Change of Control Repurchase Notice was given shall (unless such
Change of Control Repurchase Notice is withdrawn as specified in the following
paragraph) thereafter be entitled to receive solely the Change of Control
Repurchase Price with respect to such Security. Such Change of Control
Repurchase Price shall be paid to such Holder, subject to receipts of cash
and/or securities by the Paying Agent, promptly following the later of (a) the
Change of Control Repurchase Date with respect to such Security (provided the
conditions in Section 5.1(c) have been satisfied) and (b) the time of delivery
of such Security to the Paying Agent by the Holder thereof in the manner
required by Section 5.1(c). Securities in respect of which a Change of Control
Repurchase Notice has been given by the Holder thereof may not be converted
pursuant to Article XII on or after the date of the delivery of such Change of
Control Repurchase Notice unless such Change of Control Repurchase Notice has
first been validly withdrawn as specified in the following paragraph.

          A Change of Control Repurchase Notice may be withdrawn by means of a
written notice of withdrawal delivered to the office of the Paying Agent in
accordance with the Change of Control Repurchase Notice at any time prior to
5:00 p.m., New York City time, on the Business Day immediately preceding the
Change of Control Repurchase Date, specifying:

          (a)  the certificate number, if any, of the Security in respect of
     which such notice of withdrawal is being submitted;

                                       40
<Page>

          (b)  the principal amount of the Security with respect to which such
     notice of withdrawal is being submitted; and

          (c)  the principal amount, if any, of such Security which remains
     subject to the original Change of Control Repurchase Notice and which has
     been or will be delivered for repurchase by the Company.

          SECTION 5.4. DEPOSIT OF CHANGE OF CONTROL REPURCHASE PRICE.

          Prior to 10:00 a.m., New York City time, on the applicable Change of
Control Repurchase Date, the Company shall deposit with the Paying Agent (or if
the Company or a Subsidiary or an Affiliate of either of them is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an
amount of cash (in immediately available funds if deposited on such Business
Day) and/or Applicable Stock, if permitted hereunder, sufficient to pay the
aggregate Change of Control Repurchase Price of all the Securities or portions
thereof which are to be repurchased as of such Change of Control Repurchase
Date.

          If the Paying Agent holds, in accordance with the terms hereof, at
10:00 a.m., New York City time, on the applicable Change of Control Repurchase
Date, cash and/or Applicable Stock, if permitted hereunder, sufficient to pay
the Change of Control Repurchase Price of any Securities for which a Change of
Control Repurchase Notice has been tendered and not withdrawn pursuant to
Section 5.3, then, on such Change of Control Repurchase Date, such Securities
will cease to be outstanding and interest and Additional Amounts, if any, on
such Securities will cease to accrue, whether or not such Securities are
delivered to the Paying Agent, and the rights of the Holders in respect thereof
shall terminate (other than the right to receive the Change of Control
Repurchase Price upon delivery of such Securities).

          As soon as practicable on and after the Change of Control Repurchase
Date, the Company shall deliver to each Holder entitled to receive shares of
Applicable Stock through the Paying Agent, a certificate for the number of full
shares of Applicable Stock issuable in payment of the Change of Control
Repurchase Price and cash in lieu of any fractional interests. The person in
whose name the certificate for the shares of Applicable Stock is registered
shall be treated as a holder of record of Applicable Stock on the Business Day
following the Change of Control Repurchase Date. No payment or adjustment will
be made for dividends on the shares of Applicable Stock the record date for
which occurred on or prior to the Change of Control Repurchase Date.

          SECTION 5.5. SECURITIES REPURCHASED IN PART.

          Any Certificated Security which is to be repurchased only in part
shall be surrendered at the office of the Paying Agent (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Security, without charge, a new Security or Securities, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in

                                       41
<Page>

exchange for, the portion of the principal amount of the Security so surrendered
which is not repurchased.

          SECTION 5.6. COVENANT TO COMPLY WITH SECURITIES LAWS UPON REPURCHASE
OF SECURITIES.

          When complying with the provisions of Section 5.1 hereof (provided
that such offer or purchase constitutes an "issuer tender offer" for purposes of
Rule 13e-4 (which term, as used herein, includes any successor provision
thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

          (a)  comply with Rule 13e- 4 and Rule 14e-1 (or any successor
     provision) under the Exchange Act;

          (b)  file the related Schedule TO (or any successor schedule, form or
     report) under the Exchange Act; and

          (c)  otherwise comply with all Federal and state securities laws so as
     to permit the rights and obligations under Article V to be exercised in the
     time and in the manner specified therein.

          SECTION 5.7. REPAYMENT TO THE COMPANY.

          To the extent that the aggregate amount of cash or shares of
Applicable Stock deposited by the Company pursuant to Section 5.4 exceeds the
aggregate Change of Control Repurchase Price of the Securities or portions
thereof which the Company is obligated to repurchase as of the Change of Control
Repurchase Date then, promptly after the Change of Control Repurchase Date, the
Paying Agent shall return any such excess to the Company.

                                   ARTICLE VI

                                    COVENANTS

          SECTION 6.1. PAYMENT OF SECURITIES.

          The Company shall promptly make all payments in respect of the
Securities on the dates and in the manner provided in the Securities or pursuant
to this Indenture. Principal amount, Redemption Price, Repurchase Price and
Change of Control Repurchase Price and accrued and unpaid interest and
Additional Amounts, if any, shall be considered paid on the applicable date due
if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in
accordance with this Indenture, cash or securities, if permitted hereunder,
sufficient to pay all such amounts then due. The Company shall, to the fullest
extent permitted by law, pay interest on overdue principal and overdue
installments of interest and Additional Amounts, if any, at the rate borne by
the Securities per annum. All references in this Indenture or the Securities to
interest shall be deemed to include Additional Amounts, if any, payable pursuant
to the Registration Rights Agreement.

                                       42
<Page>

          Payment of the principal of and interest and Additional Amounts, if
any, on the Securities shall be in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts or in Applicable Stock, as the case may be.

          The Company shall pay interest and Additional Amounts, if any, on the
Securities to the Person in whose name the Securities are registered at the
close of business on the Regular Record Date next preceding the corresponding
Interest Payment Date. Any such interest and Additional Amounts, if any, not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may be paid (a) to the Person in whose
name the Securities are registered at the close of business on a Special Record
Date for the payment of such defaulted interest and Additional Amounts, if any,
to be fixed by the Trustee, notice whereof will be given to the Holders not less
than 10 calendar days prior to such Special Record Date or (b) at any time in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange.

          The Holder must surrender the Securities to the Paying Agent to
collect payment of principal. Payment of interest and Additional Amounts, if
any, on Certificated Securities will be made by check mailed to the address of
the Person entitled thereto as such address appears in the Register and payment
of interest and Additional Amounts, if any, on Certificated Securities in
aggregate principal amount in excess of $5,000,000 will be made by wire transfer
in immediately available funds at the election of such Holder. Notwithstanding
the foregoing, so long as the Securities are registered in the name of a
Depositary or its nominee, all payments with respect to the Securities shall be
made by wire transfer of immediately available funds to the account of the
Depositary or its nominee.

          SECTION 6.2. SEC AND OTHER REPORTS TO THE TRUSTEE.

          The Company shall ensure delivery to the Trustee within 15 calendar
days after it files such annual and quarterly reports, information, documents
and other reports with the SEC, copies of its annual report and of the
information, documents and other reports (or copies of such portions of any of
the foregoing as the SEC may by rules and regulations prescribe) which the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act in accordance with TIA Section 314(a). In the event the Company is
at any time no longer subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, it shall continue to provide the Trustee with reports
containing substantially the same information as would have been required to be
filed with the SEC had the Company continued to have been subject to such
reporting requirements. In such event, such reports shall be provided at the
times the Company would have been required to provide reports had it continued
to have been subject to such reporting requirements. The Company also shall
comply with the other provisions of TIA Section 314(a). Delivery of such
reports, information and documents to the Trustee is for informational purposes
only and the Trustee's receipt of such shall not constitute constructive notice
of any information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely conclusively on Officers'
Certificates).

                                       43
<Page>

          SECTION 6.3. COMPLIANCE CERTIFICATE.

          The Company shall deliver to the Trustee within 120 calendar days
after the end of each fiscal year of the Company (beginning with the fiscal year
ending December 31, 2003) an Officers' Certificate, stating whether or not to
the knowledge of the signers thereof, the Company is in Default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture and if the Company shall be in Default, specifying all such
Defaults and the nature and status thereof of which they may have knowledge.

          SECTION 6.4. FURTHER INSTRUMENTS AND ACTS.

          Upon request of the Trustee, or as otherwise necessary, the Company
will execute and deliver such further instruments and do such further acts as
may be reasonably necessary or proper to carry out more effectively the purposes
of this Indenture.

          SECTION 6.5. MAINTENANCE OF OFFICE OR AGENCY OF THE TRUSTEE,
REGISTRAR, PAYING AGENT AND CONVERSION AGENT.

          The Company will maintain in the Borough of Manhattan, the City of New
York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion
Agent where Securities may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer, exchange,
redemption, repurchase or conversion and where notices and demands to or upon
the Company in respect of the Securities and this Indenture may be served. The
office of The Bank of New York, 101 Barclay Street, 21st Floor West, New York,
New York 10286 (Attention: Corporate Trust Administration--Global Finance Unit),
shall initially be such office or agency for all of the aforesaid purposes. The
Company shall give prompt written notice to the Trustee of the location, and of
any change in the location, of any such office or agency (other than a change in
the location of the office of the Trustee). If at any time the Company shall
fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the address of the Trustee set forth in Section
13.2.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
PROVIDED, HOWEVER, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, for such purposes.

          SECTION 6.6. DELIVERY OF INFORMATION REQUIRED UNDER RULE 144A.

          At any time when the Company is not subject to Section 13 or 15(d) of
the Exchange Act, upon the request of a Holder or any beneficial owner of
Securities or holder or beneficial owner of Ordinary Shares issued upon
conversion thereof, the Company will promptly furnish or cause to be furnished
the information required pursuant to Rule 144A(d)(4) under the Securities Act to
such Holder or any beneficial owner of Securities or holder or beneficial owner
of Ordinary Shares, or to a prospective purchaser of any such security
designated by any such holder, as the case may be, to the extent required to
permit compliance by such Holder or holder with Rule 144A under the Securities
Act in connection with the resale of any such security.

                                       44
<Page>

Whether a person is a beneficial owner shall be determined by the Company to the
Company's reasonable satisfaction.

          SECTION 6.7. WAIVER OF STAY, EXTENSION OR USURY LAWS.

          The Company covenants (to the extent that it may lawfully do so) that
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 or any usury or
other law wherever enacted, now or at any time hereafter in force, which would
prohibit or forgive the Company from paying all or any portion of the principal
amount, Redemption Price, Repurchase Price or Change of Control Repurchase Price
in respect of Securities, or any interest and Additional Amounts, if any, on
such amounts, as contemplated herein, or which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          SECTION 6.8. STATEMENT BY OFFICERS AS TO DEFAULT.

          The Company shall deliver to the Trustee, as soon as practicable and
in any event within five Business Days after the Company becomes aware of the
occurrence of any Default or Event of Default or, an Officers' Certificate
setting forth the details of such Default or Event of Default and the action
which the Company proposes to take with respect thereto.

                                   ARTICLE VII

                              SUCCESSOR CORPORATION

          SECTION 7.1. WHEN COMPANY MAY MERGE OR TRANSFER ASSETS.

          The Company shall not consolidate with or merge with or into any other
person or convey, transfer, sell, lease or otherwise dispose of all or
substantially all of its properties and assets to any person, unless:

          (a)  either (i) the Company shall be the continuing corporation or
     (ii) the Person (if other than the Company) formed by such consolidation or
     into which the Company is merged or the Person which acquires by
     conveyance, transfer, sale, lease or other disposition all or substantially
     all of the properties and assets of the Company substantially as an
     entirety (1) shall be organized and validly existing under the laws of (A)
     the United States or any State thereof or the District of Columbia or (B)
     the Cayman Islands or Bermuda and (2) shall expressly assume, by an
     indenture supplemental hereto, executed and delivered to the Trustee, in
     form reasonably satisfactory to the Trustee, all of the obligations of the
     Company under the Securities and this Indenture;

          (b)  immediately after giving effect to such transaction, no Default
     shall have occurred and be continuing; and

                                       45
<Page>

          (c)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such (A)
     consolidation, merger, conveyance, transfer, sale, lease or other
     disposition and, if a supplemental indenture is required in connection with
     such transaction, such supplemental indenture, comply with this Article VII
     and that all conditions precedent herein provided for relating to such
     transaction have been satisfied and (B) in the case of a merger or
     consolidation in which the Company is not the continuing corporation and in
     which the successor to the Company is an entity organized under the laws of
     the Cayman Islands or Bermuda, that such merger will not result in any
     material adverse tax consequences to any Holders of the Securities.

          For purposes of the foregoing, the transfer (by lease, assignment,
sale or otherwise) of the properties and assets of one or more Subsidiaries
(other than to the Company or another Subsidiary), which, if such assets were
owned by the Company, would constitute all or substantially all of the
properties and assets of the Company, shall be deemed to be the transfer of all
or substantially all of the properties and assets of the Company.

          The successor Person formed by such consolidation or into which the
Company is merged or the successor Person to which such conveyance, transfer,
sale, lease or other disposition is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if such successor had been named as the Company herein;
and thereafter, except in the case of a lease and obligations the Company may
have under a supplemental indenture, the Company shall be discharged from all
obligations and covenants under this Indenture and the Securities. Subject to
Section 11.6, the Company, the Trustee and the successor Person shall enter into
a supplemental indenture to evidence the succession and substitution of such
successor Person and such discharge and release of the Company.

                                  ARTICLE VIII

                              DEFAULTS AND REMEDIES

          SECTION 8.1. EVENTS OF DEFAULT.

          So long as any Securities are outstanding, each of the following shall
be an "EVENT OF DEFAULT":

          (a)  the Company defaults in the payment of the principal amount of
     any Security when the same becomes due and payable at its Stated Maturity;

          (b)  the Company defaults in the payment of any accrued and unpaid
     interest and Additional Amounts, if any, in each case, when due and
     payable, and continuance of such default for a period of 30 days;

          (c)  the Company fails to convert any portion of the principal amount
     of any Security following the exercise by the Holder of the right to
     convert such Security into Ordinary Shares (or cash or a combination of
     Ordinary Shares and cash, if the Company so elects) pursuant to and in
     accordance with Article XII;

                                       46
<Page>

          (d)  the Company defaults in its obligation to redeem any Security, or
     any portion thereof, called for redemption by the Company pursuant to and
     in accordance with Article III;

          (e)  the Company defaults in its obligation to repurchase any
     Security, or any portion thereof, upon the exercise by the Holder of such
     Holder's right to require the Company to repurchase such Securities
     pursuant to and in accordance with Article IV or V;

          (f)  the Company fails to comply with any of its agreements or
     covenants in the Securities or this Indenture (other than those referred to
     in clause (a) through (e) above) and such failure continues for 60 days
     after receipt by the Company of a Notice of Default;

          (g)  the Company fails to pay when due at maturity or there occurs a
     default that results in the acceleration of maturity of any indebtedness
     for borrowed money of the Company or any Designated Subsidiary in an
     aggregate amount of $25,000,000 or more, unless the acceleration is
     rescinded, stayed or annulled within 30 days after receipt by the Company
     of a Notice of Default;

          (h)  the Company or any Designated Subsidiary, or any group of two or
     more Subsidiaries that, taken as a whole, would constitute a Designated
     Subsidiary, pursuant to or under or within the meaning of any Bankruptcy
     Law:

               (i)      commences a voluntary case or proceeding;

               (ii)     consents to the entry of any order for relief against it
     in an involuntary case or proceeding or the commencement of any case
     against it;

               (iii)    consents to the appointment of a Custodian of it or for
     any substantial part of its property;

               (iv)     makes a general assignment for the benefit of its
     creditors;

               (v)      files a petition in bankruptcy or answer or consent
     seeking reorganization or relief; or

               (vi)     consents to the filing of such petition or the
     appointment of or taking possession by a Custodian; or

          (i)  a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (i)      is for relief against the Company or any Designated
     Subsidiary, or any group of two or more Subsidiaries that, taken as whole,
     would constitute a Designated Subsidiary, in an involuntary case or
     proceeding, or adjudicates the Company or any Designated Subsidiary, or any
     group of two or more Subsidiaries that, taken as whole, would constitute a
     Designated Subsidiary, insolvent or bankrupt;

                                       47
<Page>

               (ii)     appoints a Custodian of the Company or any Designated
     Subsidiary, or any group of two or more Subsidiaries that, taken as whole,
     would constitute a Designated Subsidiary, or for any substantial part of
     its property; or

               (iii)    orders the winding up or liquidation of the Company or
     any Designated Subsidiary, or any group of two or more Subsidiaries that,
     taken as whole, would constitute a Designated Subsidiary,

     and the order of decree remains unstayed and in effect for 60 days.

          A Default under clause (f) or (g) above is not an Event of Default
until the Trustee notifies the Company, or the Holders of at least 25% in
aggregate principal amount of the Securities at the time outstanding notify the
Company and the Trustee, of the Default and the Company does not cure such
Default (and such Default is not waived) within the time specified in clause (f)
or (g) above after actual receipt of such notice. Any such notice must specify
the Default, demand that it be remedied and state that such notice is a "NOTICE
OF DEFAULT."

          SECTION 8.2. ACCELERATION.

          If an Event of Default (other than an Event of Default specified in
Section 8.1(h) or (i)) occurs and is continuing, the Trustee by notice to the
Company, or the Holders of at least 25% in aggregate principal amount of the
Securities at the time outstanding by notice to the Company and the Trustee, may
declare the principal amount plus accrued and unpaid interest and Additional
Amounts, if any, on all the Securities to be immediately due and payable. Upon
such a declaration, such accelerated amount shall be due and payable
immediately.

          If an Event of Default specified in Section 8.1(h) or (i) occurs and
is continuing, the principal amount plus accrued and unpaid interest and
Additional Amounts, if any, on all the Securities shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders.

          The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding, by notice to the Trustee (and without notice
to any other Securityholder) may rescind an acceleration and its consequences if
the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of the
principal amount plus accrued and unpaid interest and Additional Amounts, if
any, that have become due solely as a result of acceleration and if all amounts
due to the Trustee under Section 9.7 have been paid. No such rescission shall
affect any subsequent Default or impair any right consequent thereto.

          SECTION 8.3. OTHER REMEDIES.

          If an Event of Default occurs and is continuing, the Trustee may, but
shall not be obligated to, pursue any available remedy to collect the payment of
the principal amount plus accrued and unpaid interest and Additional Amounts, if
any, on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

                                       48
<Page>

          The Trustee may maintain a proceeding even if the Trustee does not
possess any of the Securities or does not produce any of the Securities in the
proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative.

          SECTION 8.4. WAIVER OF PAST DEFAULTS.

          Subject to Sections 8.7 and 11.2, the Holders of a majority in
aggregate principal amount of the Securities at the time outstanding, by notice
to the Trustee (and without notice to any other Securityholder), may waive an
existing Default and its consequences except:

          (a)  an Event of Default described in Section 8.1(a), (b), (d) or (e);

          (b)  a Default which constitutes a failure to convert any Security in
     accordance with the terms of Article XII; or

          (c)  a Default in respect of any provision of this Indenture or the
     Securities, which, under Section 11.2, cannot be amended or modified
     without the consent of each Securityholder affected thereby.

          When a Default is waived, it is deemed cured, but no such waiver shall
extend to any subsequent or other Default or impair any consequent right. This
Section 8.4 shall be in lieu of Section 316(a)1(B) of the TIA and such Section
316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the
TIA.

          SECTION 8.5. CONTROL BY MAJORITY.

          The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee determines in good faith is prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability unless the
Trustee is offered indemnity satisfactory to it. This Section 8.5 shall be in
lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby
expressly excluded from this Indenture, as permitted by the TIA.

          SECTION 8.6. LIMITATION ON SUITS.

          A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities unless:

          (a)  the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

     Securities at the time outstanding make a written request to the Trustee to
     pursue the remedy;

                                       49

          (c)  such Holder or Holders offer to the Trustee security or indemnity
     satisfactory to the Trustee against any loss, liability or expense;

          (d)  the Trustee does not comply with the request within 60 days after
     receipt of such notice, request and offer of security or indemnity; and

          (e)  the Holders of a majority in aggregate principal amount of the
     Securities at the time outstanding do not give the Trustee a direction
     inconsistent with the request during such 60-day period.

          A Securityholder may not use this Indenture to prejudice the rights of
any other Securityholder or to obtain a preference or priority over any other
Securityholder.

          SECTION 8.7. RIGHTS OF HOLDERS TO RECEIVE PAYMENT OR TO CONVERT.

          Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of the principal amount, Redemption Price,
Repurchase Price, Change of Control Repurchase Price or interest and Additional
Amounts, if any, in respect of the Securities held by such Holder, on or after
the respective due dates expressed in the Securities and in this Indenture, and
to convert such Securities in accordance with Article XII, or to bring suit for
the enforcement of any such payment on or after such respective dates or the
right to convert, is absolute and unconditional and shall not be impaired or
affected adversely without the consent of such Holder.

          SECTION 8.8. COLLECTION SUIT BY TRUSTEE.

          If an Event of Default described in Section 8.1(a), (b), (d) or (e)
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company or another obligor on the
Securities for the whole amount owing with respect to the Securities and the
amounts provided for in Section 9.7.

          SECTION 8.9. TRUSTEE MAY FILE PROOFS OF CLAIM.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal amount, Redemption
Price, Repurchase Price, Change of Control Repurchase Price or interest and
Additional Amounts, if any, in respect of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
any such amount) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

          (a)  to file and prove a claim for the whole amount of the principal
     amount, Redemption Price, Repurchase Price, Change of Control Repurchase
     Price, or interest and Additional Amounts, if any, and to file such other
     papers or documents as may be necessary or advisable in order to have the
     claims of the Trustee (including any claim for the reasonable compensation,
     expenses, disbursements and advances of the Trustee, its

                                       50
<Page>

     agents and counsel or any other amounts due the Trustee under Section 9.7)
     and of the Holders allowed in such judicial proceeding, and

          (b)  to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.7.

          Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

          SECTION 8.10. PRIORITIES.

          If the Trustee collects any money pursuant to this Article VIII, it
shall pay out the money in the following order:

          FIRST: to the Trustee for amounts due under Section 9.7;

          SECOND: to Securityholders for amounts due and unpaid on the
     Securities for the principal amount, Redemption Price, Repurchase Price,
     Change of Control Repurchase Price or interest and Additional Amounts, if
     any, as the case may be, ratably, without preference or priority of any
     kind, according to such amounts due and payable on the Securities; and

          THIRD: the balance, if any, to the Company.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 8.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder and the Company a
notice that states the record date, the payment date and the amount to be paid.

          SECTION 8.11. UNDERTAKING FOR COSTS.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant (other than the Trustee) in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 8.11 does not apply to a suit
by the Trustee, a suit by a Holder pursuant to Section 8.7 or a suit by Holders
of more than 10% in aggregate principal amount of the

                                       51
<Page>

Securities at the time outstanding. This Section 8.11 shall be in lieu of
Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded
from this Indenture, as permitted by the TIA.

                                   ARTICLE IX

                                     TRUSTEE

          SECTION 9.1. DUTIES OF TRUSTEE.

          (a)  If an Event of Default has occurred and is continuing, the
Trustee shall exercise the rights and powers vested in it by this Indenture and
use the same degree of care and skill in its exercise of those rights and powers
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

          (b)  Except during the continuance of an Event of Default:

               (i)      the Trustee need perform only those duties that are
     specifically set forth in this Indenture and no others; and

               (ii)     in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture, but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     examine the certificates and opinions to determine whether or not they
     conform to the requirements of this Indenture, but need not confirm or
     investigate the accuracy of mathematical calculations or other facts stated
     therein.

This Section 9.1(b) shall be in lieu of Section 315(a) of the TIA and such
Section 315(a) is hereby expressly excluded from this Indenture, as permitted by
the TIA.

          (c)  The Trustee may not be relieved from liability for its own
grossly negligent action, its own grossly negligent failure to act or its own
willful misconduct, except that:

               (i)      this Section (c) does not limit the effect of
     Section (b) of this Section 9.1;

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

               (iii)    the Trustee shall not be liable with respect to any
     action it takes or omits to take in good faith in accordance with a
     direction received by it pursuant to Section 8.5.

                                       52
<Page>

Subparagraphs (c)(i), (ii) and (iii) shall be in lieu of Sections 315(d)(1),
315(d)(2) and 315(d)(3) of the TIA, respectively, and such Sections 315(d)(1),
315(d)(2) and 315(d)(3) are hereby expressly excluded from this Indenture, as
permitted by the TIA.

          (d)  Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 9.1.

          (e)  The Trustee may refuse to perform any duty or exercise any right
or power or extend or risk its own funds or otherwise incur any financial
liability unless it receives indemnity satisfactory to it against any loss,
liability or expense.

          (f)  Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
(acting in any capacity hereunder) shall be under no liability for interest on
any money received by it hereunder unless otherwise agreed in writing with the
Company.

          SECTION 9.2. RIGHTS OF TRUSTEE.

          Subject to its duties and responsibilities under the TIA,

          (a)  the Trustee may conclusively rely and shall be protected in
     acting or refraining from acting upon any resolution, certificate,
     statement, instrument, opinion, report, notice, request, direction,
     consent, order, bond, debenture, note, other evidence of indebtedness or
     other paper or document believed by it to be genuine and to have been
     signed or presented by the proper party or parties;

          (b)  whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, conclusively rely upon an Officers' Certificate;

          (c)  the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder;

          (d)  the Trustee shall not be liable for any action taken, suffered,
     or omitted to be taken by it in good faith which it believes to be
     authorized or within its rights or powers conferred under this Indenture;

          (e)  the Trustee may consult with counsel selected by it and any
     advice or Opinion of Counsel shall be full and complete authorization and
     protection in respect of any action taken or suffered or omitted by it
     hereunder in good faith and in reliance on such advice or Opinion of
     Counsel;

          (f)  the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the

                                       53
<Page>

     Holders, pursuant to the provisions of this Indenture, unless such Holders
     shall have offered to the Trustee security or indemnity satisfactory to it
     against the costs, expenses and liabilities which may be incurred therein
     or thereby;

          (g)  any request or direction of the Company mentioned herein shall be
     sufficiently evidenced by a Company Request or Company Order and any
     resolution of the Board of Directors may be sufficiently evidenced by a
     Board Resolution;

          (h)  the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney at the sole cost of the Company
     and shall incur no liability or additional liability of any kind by reason
     of such inquiry or investigation;

          (i)  the Trustee shall not be deemed to have notice of any Default or
     Event of Default unless a Responsible Officer of the Trustee has actual
     knowledge thereof or unless written notice of any event which is in fact
     such a default is received by the Trustee at the Corporate Trust Office of
     the Trustee, and such notice references the Securities and this Indenture;

          (j)  the rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and to each agent, custodian and other
     person employed to act hereunder; and

          (k)  the Trustee may request that the Company deliver an Officers'
     Certificate setting forth the names of individuals and/or titles of
     officers authorized at such time to take specified actions pursuant to this
     Indenture, which Officers' Certificate may be signed by any person
     authorized to sign an Officers' Certificate, including any person specified
     as so authorized in any such certificate previously delivered and not
     superseded.

          SECTION 9.3. INDIVIDUAL RIGHTS OF TRUSTEE.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee. Any Paying
Agent, Registrar, Conversion Agent or co-registrar may do the same with like
rights. However, the Trustee must comply with Sections 9.10 and 9.11.

          SECTION 9.4. TRUSTEE'S DISCLAIMER.

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use or application of the proceeds from the Securities, it shall not be
responsible for any statement in any registration

                                       54
<Page>

statement for the Securities under the Securities Act or in any offering
document for the Securities, this Indenture or the Securities (other than its
certificate of authentication), or the determination as to which beneficial
owners are entitled to receive any notices hereunder.

          SECTION 9.5. NOTICE OF DEFAULTS.

          If a Default occurs and if it is known to the Trustee, the Trustee
shall give to each Securityholder notice of the Default within 90 days after it
occurs or, if later, within 15 days after it is known to the Trustee, unless
such Default shall have been cured or waived before the giving of such notice.
Notwithstanding the preceding sentence, except in the case of a Default
described in Section 8.1(a), (b), (d) or (e), the Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interest of the
Securityholders. The preceding sentence shall be in lieu of the proviso to
Section 315(b) of the TIA and such proviso is hereby expressly excluded from
this Indenture, as permitted by the TIA.

          SECTION 9.6. REPORTS BY TRUSTEE TO HOLDERS.

          Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to each Securityholder a
brief report dated as of such May 15 that complies with TIA Section 313(a), if
required by such Section 313(a). The Trustee also shall comply with TIA Section
313(b).

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each securities exchange, if any, on which the
Securities are listed. The Company agrees to notify the Trustee promptly
whenever the Securities become listed on any securities exchange and of any
delisting thereof.

          SECTION 9.7. COMPENSATION AND INDEMNITY.

          The Company agrees to:

          (a)  pay to the Trustee from time to time such compensation as the
     Company and the Trustee shall from time to time agree in writing for all
     services rendered by it hereunder (which compensation shall not be limited
     (to the extent permitted by law) by any provision of law in regard to the
     compensation of a trustee of an express trust);

          (b)  reimburse the Trustee upon its request for all expenses,
     disbursements and advances incurred or made by the Trustee in accordance
     with any provision of this Indenture (including the compensation and the
     expenses, advances and disbursements of its agents and counsel), except any
     such expense, disbursement or advance as may be attributable to its own
     gross negligence or willful misconduct; and

          (c)  fully indemnify the Trustee or any predecessor Trustee and their
     agents for, and to hold them harmless against, any and all loss, damage,
     claim, liability, cost or expense (including attorney's fees and expenses,
     and taxes (other than taxes based upon, measured by or determined by the
     income of the Trustee)) incurred without gross negligence or willful
     misconduct on its part, arising out of or in connection with the

                                       55
<Page>

     acceptance or administration of this trust, including the costs and
     expenses of defending itself against any claim (whether asserted by the
     Company or any Holder or any other person) or liability in connection with
     the exercise or performance of any of its powers or duties hereunder, or in
     connection with enforcing the provisions of this Section 9.7.

          The Trustee shall have the right to employ separate counsel in any
such action or proceeding and participate in the investigation and defense
thereof, and the Company shall pay the reasonable fees and expenses of such
separate counsel; PROVIDED, HOWEVER, that the Trustee may only employ separate
counsel at the expense of the Company if in the judgment of the Trustee (i) a
conflict of interest exists by reason of common representation or (ii) there are
legal defenses available to the Trustee that are different from or are in
addition to those available to the Company or if all parties commonly
represented do not agree as to the action (or inaction) of counsel.

          To secure the Company's payment obligations in this Section 9.7, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, except that held in trust to pay the principal
amount, Redemption Price, Repurchase Price, Change of Control Repurchase Price
or interest and Additional Amounts, if any, as the case may be, on particular
Securities.

          The Company's payment obligations pursuant to this Section 9.7 shall
survive the discharge of this Indenture and the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 8.1(h) or (i), the expenses including the reasonable
charges and expenses of its counsel, are intended to constitute expenses of
administration under any Bankruptcy Law.

          SECTION 9.8. REPLACEMENT OF TRUSTEE.

          The Trustee may resign by so notifying the Company; PROVIDED, HOWEVER,
that no such resignation shall be effective until a successor Trustee has
accepted its appointment pursuant to this Section 9.8. The Holders of a majority
in aggregate principal amount of the Securities at the time outstanding may
remove the Trustee by so notifying the Trustee and the Company. The Company
shall remove the Trustee if:

          (a)  the Trustee fails to comply with Section 9.10;

          (b)  the Trustee is adjudged bankrupt or insolvent;

          (c)  a receiver or public officer takes charge of the Trustee or its
     property; or

          (d)  the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint, by
resolution of its Board of Directors, a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company satisfactory in form and
substance to the retiring Trustee

                                       56
<Page>

and the Company. Thereupon the resignation or removal of the retiring Trustee
shall become effective, and the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture. The successor Trustee
shall mail a notice of its succession to Securityholders. The retiring Trustee
shall promptly transfer all property held by it as Trustee to the successor
Trustee, subject to the lien provided for in Section 9.7.

          If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of a majority in aggregate principal amount of the Securities at the
time outstanding may petition at the expense of the Company any court of
competent jurisdiction at the expense of the Company for the appointment of a
successor Trustee.

          If the Trustee fails to comply with Section 9.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          SECTION 9.9. SUCCESSOR TRUSTEE BY MERGER.

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all its corporate trust business or assets to,
another corporation, the resulting, surviving or transferee corporation without
any further act shall be the successor Trustee.

          SECTION 9.10. ELIGIBILITY; DISQUALIFICATION.

          The Trustee shall at all times satisfy the requirements of TIA
Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recent published annual report of condition. Nothing contained herein shall
prevent the Trustee from filing with the Commission the application referred to
in the penultimate paragraph of TIA Section 310(b).

          SECTION 9.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated
therein.

                                    ARTICLE X

                             DISCHARGE OF INDENTURE

          SECTION 10.1. DISCHARGE OF LIABILITY ON SECURITIES.

          When (i) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced or repaid pursuant to Section 2.7)
for cancellation or (ii) all outstanding Securities have become due and payable
(whether at the Stated Maturity or upon acceleration, or on any Redemption Date,
Repurchase Date or Change of Control Repurchase Date, or upon conversion) and
the Company deposits with the Paying Agent or Conversion Agent cash or
Applicable Stock sufficient to pay all amounts due and owing on all outstanding
Securities (other

                                       57
<Page>

than Securities replaced pursuant to Section 2.7), and if in either case the
Company pays all other sums payable hereunder by the Company, then this
Indenture shall, subject to Section 9.7, cease to be of further effect. The
Trustee shall join in the execution of a document prepared by the Company
acknowledging satisfaction and discharge of this Indenture on demand of the
Company accompanied by an Officers' Certificate and Opinion of Counsel and at
the cost and expense of the Company.

          SECTION 10.2. REPAYMENT TO THE COMPANY.

          The Trustee and the Paying Agent shall return to the Company upon
written request any cash or securities held by them for the payment of any
amount with respect to the Securities that remains unclaimed for two years,
subject to applicable unclaimed property law. After return to the Company,
Holders entitled to the cash or securities must look to the Company for payment
as general creditors unless an applicable abandoned property law designates
another person and the Trustee and the Paying Agent shall have no further
liability to the Securityholders with respect to such cash or securities for
that period commencing after the return thereof.

                                   ARTICLE XI

                                   AMENDMENTS

          SECTION 11.1. WITHOUT CONSENT OF HOLDERS.

          The Company and the Trustee may amend this Indenture or the Securities
without the consent of any Securityholder to:

          (a)  add to the covenants of the Company for the benefit of the
     Holders of Securities;

          (b)  surrender any right or power herein conferred upon the Company;

          (c)  provide for conversion rights of Holders of Securities if any
     reclassification or change of the Ordinary Shares or any consolidation,
     merger or sale of all or substantially all of the Company's assets occurs;

          (d)  provide for the assumption of the Company's obligations to the
     Holders of Securities in the case of a merger, consolidation, conveyance,
     transfer, sale, lease or other disposition pursuant to Article VII;

          (e)  reduce the Conversion Price; PROVIDED, HOWEVER, that such
     reduction in the Conversion Price shall not adversely affect the interests
     of the Holders of Securities (after taking into account tax and other
     consequences of such reduction);

          (f)  comply with the requirements of the SEC in order to effect or
     maintain the qualification of this Indenture under the TIA;

          (g)  make any changes or modifications necessary in connection with
     the registration of the Securities under the Securities Act as contemplated
     in the Registration

                                       58
<Page>

     Rights Agreement; PROVIDED, HOWEVER, that such action pursuant to this
     clause (g) does not, in the good faith opinion of the Board of Directors of
     the Company (as evidenced by a Board Resolution) and the Trustee, adversely
     affect the interests of the Holders of Securities in any material respect;

          (h)  cure any ambiguity, correct or supplement any provision herein
     which may be inconsistent with any other provision herein or which is
     otherwise defective, or to make any other provisions with respect to
     matters or questions arising under this Indenture which the Company may
     deem necessary or desirable and which shall not be inconsistent with the
     provisions of this Indenture; PROVIDED, HOWEVER, that such action pursuant
     to this clause (h) does not, in the good faith opinion of the Board of
     Directors of the Company (as evidenced by a Board Resolution) and the
     Trustee, adversely affect the interests of the Holders of Securities in any
     material respect; and

          (i)  add or modify any other provisions herein with respect to matters
     or questions arising hereunder which the Company and the Trustee may deem
     necessary or desirable and which will not adversely affect the interests of
     the Holders of Securities.

          SECTION 11.2. WITH CONSENT OF HOLDERS.

          Except as provided below in this Section 11.2, this Indenture or the
Securities may be amended, modified or supplemented, and noncompliance in any
particular instance with any provision of this Indenture or the Securities may
be waived, in each case with the written consent or affirmative vote of the
Holders of at least a majority of the principal amount of the Securities at the
time outstanding.

          Without the written consent or the affirmative vote of each Holder of
Securities affected thereby (in addition to the written consent or the
affirmative vote of the holders of at least a majority of the principal amount
of the Securities at the time outstanding), an amendment or waiver under this
Section 11.2 may not:

          (a)  change the maturity of the principal amount of, or the payment
     date of any installment of interest or Additional Amounts, if any, on, any
     Security;

          (b)  reduce the principal amount of, or interest or Additional
     Amounts, if any, on, or the Redemption Price, Repurchase Price or Change of
     Control Repurchase Price of, any Security;

          (c)  change the currency of payment of principal amount of, or
     interest or Additional Amounts, if any, on, or the Redemption Price,
     Repurchase price or Change of Control Repurchase Price of, any Security
     from U.S. Dollars;

          (d)  alter or otherwise modify the rate of interest or Additional
     Amounts, if any, on any Security, or the manner of calculation thereof;

          (e)  impair the right of any Holder to institute suit for the
     enforcement of any payment or with respect to, or conversion of, any
     Security;

                                       59
<Page>

          (f)  modify the obligation of the Company to maintain an agency in The
     City of New York pursuant to Section 6.5;

          (g)  impair or adversely affect the conversion rights of the Holder of
     the Securities as provided in Article XII;

          (h)  impair or adversely affect the repurchase rights of the Holders
     of the Securities as provided in Articles IV and V;

          (i)  modify the optional redemption provisions of Article III in a
     manner adverse to the Holders of the Securities;

          (j)  reduce the percentage of the principal amount of the outstanding
     Securities the written consent or affirmative vote of whose Holders is
     required for any such supplemental indenture; or

          (k)  reduce the percentage of the principal amount of the outstanding
     Securities the written consent or affirmative vote of whose Holders is
     required for any waiver of any past Default provided for in this Indenture.

          It shall not be necessary for the consent of the Holders under this
Section 11.2 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

          After an amendment under this Section 11.2 becomes effective, the
Company shall mail to each Holder a notice briefly describing the amendment.

          Nothing contained in this Section 11.2 shall impair the ability of the
Company and the Trustee to amend this Indenture or the Securities without the
consent of any Securityholder to provide for the assumption of the Company's
obligations to the Holders of Securities in the case of a merger, consolidation,
conveyance, transfer, sale, lease or other disposition pursuant to Article VII.

          SECTION 11.3. COMPLIANCE WITH TRUST INDENTURE ACT.

          Every supplemental indenture executed pursuant to this Article shall
comply with the TIA.

          SECTION 11.4. REVOCATION AND EFFECT OF CONSENTS, WAIVERS AND ACTIONS.

          Until an amendment, waiver or other action by Holders becomes
effective, a consent thereto by a Holder of a Security hereunder is a continuing
consent by the Holder and every subsequent Holder of that Security or portion of
the Security that evidences the same obligation as the consenting Holder's
Security, even if notation of the consent, waiver or action is not made on the
Security. However, any such Holder or subsequent Holder may revoke the consent,
waiver or action as to such Holder's Security or portion of the Security if the
Trustee receives the notice of revocation before the date the amendment, waiver
or action becomes

                                       60
<Page>

effective. After an amendment, waiver or action becomes effective, it shall bind
every Securityholder.

          SECTION 11.5. NOTATION ON OR EXCHANGE OF SECURITIES.

          Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article XI may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for outstanding Securities.

          SECTION 11.6. TRUSTEE TO SIGN SUPPLEMENTAL INDENTURES.

          The Trustee shall sign any supplemental indenture authorized pursuant
to this Article XI if the amendment contained therein does not affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign such supplemental indenture. In signing such
supplemental indenture the Trustee shall receive, and (subject to the provisions
of Section 9.1) shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel stating that such amendment is authorized
or permitted by this Indenture.

          SECTION 11.7. EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

                                   ARTICLE XII

                                   CONVERSION

          SECTION 12.1. CONVERSION RIGHT.

          (a)  Subject to and upon compliance with the provisions of this
Article XII, a Holder of a Security shall have the right, at such Holder's
option, to convert all or any portion (if the portion to be converted is $1,000
or an integral multiple of $1,000) of such Security into, subject to Section
12.13, Ordinary Shares at the Conversion Price in effect on the date of
conversion:

               (i)      during any Conversion Period, if the Sale Price of the
     Ordinary Shares for at least 20 Trading Days in the 30 consecutive Trading
     Day period ending on the first day of such Conversion Period exceeds 120%
     of the Conversion Price in effect on such 30th Trading Day;

               (ii)     during any period in which the Securities are rated by
     either Moody's or Standard & Poor's and the credit rating assigned to the
     Securities by either

                                       61
<Page>

     rating agency is downgraded by two levels or more, suspended or withdrawn,
     PROVIDED that the Company has no obligation to have the notes rated;

               (iii)    if such Security has been called for redemption pursuant
     to Article III; or

               (iv)     as provided in Section (b) of this Section 12.1.

          The Conversion Agent shall, on behalf of the Company, determine on a
daily basis whether the Securities shall be convertible as a result of the
occurrence of an event specified in clause (i) above and, if the Securities
shall be so convertible, the Conversion Agent shall promptly deliver to the
Company and the Trustee written notice thereof. Whenever the Securities shall
become convertible pursuant to this Section 12.1, the Company or, at the
Company's request, the Trustee in the name and at the expense of the Company,
shall notify the Holders of the event triggering such convertibility in the
manner provided in Section 13.2, and the Company shall also publicly announce
such information and publish it on the Company's Website. Any notice so given
shall be conclusively presumed to have been duly given, whether or not the
Holder receives such notice.

          (b)  (i)      In the event that:

                        (A)     the Company distributes to all holders of its
          Ordinary Shares rights or warrants entitling them (for a period
          expiring within 60 days of the Record Date for such distribution) to
          subscribe for or purchase Ordinary Shares at a price per Ordinary
          Share less than the Sale Price of the Ordinary Shares on the Business
          Day immediately preceding the announcement of such distribution;

                        (B)     the Company distributes to all holders of its
          Ordinary Shares cash or other assets, debt securities or rights or
          warrants to purchase its securities, where the Fair Market Value (as
          determined by the Board of Directors) of such distribution per
          Ordinary Share exceeds 10% of the Sale Price of the Ordinary Shares on
          the Business Day immediately preceding the date of declaration of such
          distribution; or

                        (C)     a Change of Control occurs,

then, in each case, the Securities may be surrendered for conversion at any time
on and after the date that the Company gives notice to the Holders of such
right, which shall be, in the case of (A) or (B), not less than 20 days prior to
the Ex-Dividend Time for such distribution, or, in the case of (C), within 30
days after the occurrence of the Change of Control, until 5:00 p.m., New York
City time, on, in the case of (A) or (B), the earlier of the Business Day
immediately preceding the Ex-Dividend Time and the date the Company announces
that such distribution will not take place or, in the case of (C), the earlier
of the 30th day after the Company's delivery of the notice of the change of
control and the date the Company announces that the Change of Control will not
take place; PROVIDED, HOWEVER, that in the case of (A) or (B), a Holder of
Securities may not surrender Securities for conversion if the Holder will
otherwise participate in such distribution without conversion.

                                       62
<Page>

               (ii)     In addition, in the event that the Company consolidates
with or merges into another corporation, or is a party to a binding share
exchange pursuant to which the Ordinary Shares would be converted into cash,
securities or other property as set forth in Section 12.4, then the Securities
may be surrendered for conversion at any time from and after the date which is
15 calendar days prior to the date announced by the Company as the anticipated
effective time of such transaction until 15 calendar days after the actual date
of such transaction.

          SECTION 12.2. CONVERSION PROCEDURE; CONVERSION PRICE; FRACTIONAL
SHARES.

          (a)  Subject to Section 12.13, each Security shall be convertible at
the office of the Conversion Agent into fully paid and nonassessable Ordinary
Shares (calculated to the nearest 1/10,000th of a share). The number of Ordinary
Shares issuable upon conversion of a Security shall be determined by dividing
the principal amount of the Security or portion thereof surrendered for
conversion by the Conversion Price in effect on the date of conversion.

          The Conversion Agent shall notify the Company when it receives a
Conversion Notice. The Company shall determine the number of Ordinary Shares
and/or the amount of cash, if any, that the Holder that submitted the Conversion
Notice is entitled to receive upon surrender of the Securities covered by that
Conversion Notice.

          No payment or adjustment shall be made in respect of dividends or
distributions on the Ordinary Shares issued upon conversion or accrued and
unpaid interest or Additional Amounts, if any, on a converted Security, except
as described in Section 12.9.

          The Company will not issue any fraction of an Ordinary Share in
connection with any conversion of Securities. Instead, the Company will, subject
to Section 12.3(h), make a cash payment (calculated to the nearest cent) equal
to such fraction multiplied by the Sale Price of the Ordinary Shares on the last
Trading Day prior to the date of conversion.

          Notwithstanding the foregoing, a Security in respect of which a Holder
has delivered a Repurchase Notice or a Change of Control Repurchase Notice
exercising such Holder's right to require the Company to repurchase such
Security may be converted only if such Repurchase Notice or Change of Control
Repurchase Notice, as the case may be, is withdrawn in accordance with the
Section 4.3 or 5.3, as the case may be, prior to 5:00 p.m., New York City time,
on the Business Day immediately preceding the applicable Repurchase Date or
Change of Control Repurchase Date, as the case may be.

          (b)  Before any Holder of a Security shall be entitled to convert the
same into Ordinary Shares, such Holder shall, in the case of Global Securities,
comply with the Applicable Procedures of the Depositary in effect at that time,
and in the case of Certificated Securities, surrender such Securities, duly
endorsed to the Company or in blank, at the office of the Conversion Agent, and
shall give written notice to the Company at said office or place in the form of
the Conversion Notice attached to the Security (the "CONVERSION NOTICE") that
such Holder elects to convert the same and shall state in writing therein the
principal amount of Securities to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for
Ordinary Shares to be issued.

                                       63
<Page>

          Before any such conversion, a Holder also shall pay all funds
required, if any, relating to interest or Additional Amounts, if any, on the
Securities, as provided in Section 12.9, and all taxes or duties, if any, as
provided in Section 12.8.

          If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full Ordinary Shares which shall be
deliverable upon conversion shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof to the extent
permitted thereby) so surrendered. Subject to the next succeeding sentence, the
Company will, as soon as practicable thereafter, issue and deliver at said
office or place to such Holder of a Security, or to such Holder's nominee or
nominees, certificates for the number of full Ordinary Shares to which such
Holder shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share to which such Holder would otherwise be entitled. The
Company shall not be required to deliver certificates for Ordinary Shares while
the stock transfer books for such stock or the security register are duly closed
for any purpose, but certificates for Ordinary Shares shall be issued and
delivered as soon as practicable after the opening of such books or security
register.

          If Ordinary Shares to be issued upon conversion of a Restricted
Security are to be issued in the name of a Person other than the Holder of such
Restricted Security, such Holder must deliver to the Conversion Agent a
certification in substantially the form set forth in a Transfer Certificate
dated the date of surrender of such Restricted Security and signed by such
Holder, as to compliance with the restrictions on transfer applicable to such
Restricted Security. The Company shall not be required to issue Ordinary Shares
upon conversion of any such Restricted Security to a Person other than the
Holder if such Restricted Security is not so accompanied by a properly completed
certification, and the Registrar shall not be required to register Ordinary
Shares upon conversion of any such Restricted Security in the name of a Person
other than the Holder if such Restricted Security is not so accompanied by a
properly completed certification.

          (c)  A Security shall be deemed to have been converted immediately
prior to 5:00 p.m., New York City time, on the date of the surrender of such
Securities for conversion as provided above, and the person or persons entitled
to receive the Ordinary Shares issuable upon such conversion shall be treated
for all purposes as the record Holder or Holders of such Ordinary Shares as of
5:00 p.m., New York City time, on such date.

          (d)  In case any Certificated Security shall be surrendered for
partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to or upon the written order of the Holder of the Security so
surrendered, without charge to such Holder (subject to the provisions of Section
12.8), a new Security or Securities in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered
Certificated Securities.

          SECTION 12.3. ADJUSTMENT OF CONVERSION PRICE FOR ORDINARY SHARES.

          The Conversion Price shall be adjusted from time to time as follows:

                                       64
<Page>

          (a)  In case the Company shall, at any time or from time to time while
any of the Securities are outstanding, pay a dividend or make a distribution in
Ordinary Shares to all holders of its outstanding Ordinary Shares, then the
Conversion Price in effect at the opening of business on the date next following
the Record Date fixed for the determination of shareholders entitled to receive
such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction:

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

       (ii) the denominator of which shall be the sum of such number of Ordinary
     Shares and the total number of Ordinary Shares constituting such dividend
     or other distribution.

               Such reduction shall become effective immediately after the
opening of business on the day following the Record Date fixed for such
determination. If any dividend or distribution of the type described in this
Section 12.3(a) is declared but not so paid or made, the Conversion Price shall
again be adjusted to the Conversion Price which would then be in effect if such
dividend or distribution had not been declared.

          (b)  In case the Company shall, at any time or from time to time while
any of the Securities are outstanding, subdivide its outstanding Ordinary Shares
into a greater number of Ordinary Shares, then the Conversion Price in effect at
the opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately reduced, and conversely, in case the
Company shall, at any time or from time to time while any of the Securities are
outstanding, combine its outstanding shares of Ordinary Shares into a smaller
number of Ordinary Shares, then the Conversion Price in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately increased.

               Such reduction or increase, as the case may be, shall become
effective immediately after the opening of business on the day following the day
upon which such subdivision or combination becomes effective.

          (c)  In case the Company shall, at any time or from time to time while
any of the Securities are outstanding, issue rights or warrants for a period
expiring within 60 days (other than any rights or warrants referred to in
Section 12.3(d)) to all holders of its outstanding Ordinary Shares entitling
them to subscribe for or purchase Ordinary Shares (or securities convertible
into or exchangeable or exercisable for Ordinary Shares), at a price per
Ordinary Share (or having a conversion, exchange or exercise price per Ordinary
Share) less than the Sale Price of the Ordinary Shares on the Business Day
immediately preceding the date of the announcement of such issuance (treating
the conversion, exchange or exercise price per Ordinary Share of the securities
convertible into Ordinary Shares as equal to (x) the sum of (i) the price for a
unit of the security convertible into or exchangeable or exercisable for
Ordinary Shares and (ii) any additional consideration initially payable upon the
conversion of or exchange or exercise for such security into Ordinary Shares
divided by (y) the number of Ordinary Shares initially underlying such
convertible, exchangeable or exercisable security), then the Conversion Price
shall be adjusted so that the same shall equal the price determined by
multiplying the Conversion

                                       65
<Page>

Price in effect at the opening of business on the date after such date of
announcement by a fraction:

        (i) the numerator of which shall be the number of Ordinary Shares
     outstanding on the close of business on the date of announcement, plus the
     number of Ordinary Shares (or convertible, exchangeable or exercisable
     securities) which the aggregate offering price of the total number of
     Ordinary Shares (or convertible, exchangeable or exercisable securities) so
     offered for subscription or purchase (or the aggregate conversion, exchange
     or exercise price of the convertible, exchangeable or exercisable
     securities so offered) would purchase at such Sale Price of the Ordinary
     Shares; and

       (ii) the denominator of which shall be the number of Ordinary Shares
     outstanding at the close of business on the date of announcement, plus the
     total number of additional Ordinary Shares so offered for subscription or
     purchase (or into which the convertible, exchangeable or exercisable
     securities so offered are convertible, exchangeable or exercisable).

               Such adjustment shall become effective immediately after the
opening of business on the day following the date of announcement of such
issuance. To the extent that Ordinary Shares (or securities convertible,
exchangeable or exercisable into Ordinary Shares) are not delivered pursuant to
such rights or warrants, upon the expiration or termination of such rights or
warrants, the Conversion Price shall be readjusted to the Conversion Price which
would then be in effect had the adjustments made upon the issuance of such
rights or warrants been made on the basis of the delivery of only the number of
Ordinary Shares (or securities convertible, exchangeable or exercisable into
Ordinary Shares) actually delivered. In the event that such rights or warrants
are not so issued, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if the date fixed for the
determination of shareholders entitled to receive such rights or warrants had
not been fixed. In determining whether any rights or warrants entitle the
holders to subscribe for or purchase Ordinary Shares at less than such Sale
Price, and in determining the aggregate offering price of such Ordinary Shares,
there shall be taken into account any consideration received for such rights or
warrants, the value of such consideration if other than cash, to be determined
by the Board of Directors.

          (d)  (A)      In case the Company shall, at any time or from time to
time while any of the Securities are outstanding, by dividend or otherwise,
distribute to all holders of its outstanding Ordinary Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation and the Ordinary Shares are not changed or
exchanged), shares of its capital stock evidences of its Indebtedness or other
assets, including securities, but excluding (i) dividends or distributions of
Ordinary Shares referred to in Section 12.3(a), (ii) any rights or warrants
referred to in Section 12.3(c), (iii) dividends and distributions paid
exclusively in cash referred to in Section 12.3(e) and (iv) dividends and
distributions of stock, securities or other property or assets (including cash)
in connection with the reclassification, change, merger, consolidation,
statutory share exchange, combination, sale or conveyance to which Section 12.4
applies (such capital stock, evidence of its indebtedness, other assets or
securities being distributed hereinafter in this Section 12.3(d) called the
"DISTRIBUTED ASSETS"), then, in each such case, subject to paragraphs (D) and
(E) of this Section 12.3(d), the Conversion Price shall be reduced so that the
same shall be equal to the

                                       66
<Page>

price determined by multiplying the Conversion Price in effect immediately prior
to the close of business on the Record Date with respect to such distribution by
a fraction:

        (i) the numerator of which shall be the Current Market Price of the
     Ordinary Shares, less the Fair Market Value on such date of the portion of
     the distributed assets so distributed applicable to one Ordinary Share
     (determined on the basis of the number of Ordinary Shares outstanding on
     the Record Date)(determined as provided in Section 12.3(g)) on such date;
     and

       (ii) the denominator of which shall be such Current Market Price.

               Such reduction shall become effective immediately prior to the
opening of business on the day following the Record Date for such distribution.
In the event that such dividend or distribution is not so paid or made, the
Conversion Price shall again be adjusted to be the Conversion Price which would
then be in effect if such dividend or distribution had not been declared.

               (B)      If the Board of Directors determines the Fair Market
Value of any distribution for purposes of this Section 12.3(d) by reference to
the actual or when issued trading market for any distributed assets comprising
all or part of such distribution, it must in doing so consider the prices in
such market over the same period (the "REFERENCE PERIOD") used in computing the
Current Market Price pursuant to Section 12.3(g) to the extent possible, unless
the Board of Directors determines in good faith that determining the Fair Market
Value during the Reference Period would not be in the best interest of the
Holders.

               (C)      In the event any such distribution consists of shares of
capital stock of, or similar equity interests in, one or more of the Company's
Subsidiaries (a "SPIN-OFF"), the Fair Market Value of the securities to be
distributed shall equal the average of the closing sale prices of such
securities on the principal securities market on which such securities are
traded for the five consecutive Trading Days commencing on and including the
sixth Trading Day of those securities after the effectiveness of the Spin-Off,
and the Current Market Price shall be measured for the same period. In the
event, however, that an underwritten initial public offering of the securities
in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of
the securities distributed in the Spin-Off shall mean the initial public
offering price of such securities and the Current Market Price shall mean the
Sale Price for the Ordinary Shares on the same Trading Day.

               (D)      Rights or warrants distributed by the Company to all
holders of its outstanding Ordinary Shares entitling them to subscribe for or
purchase shares of the Company's capital stock (either initially or under
certain circumstances), which rights or warrants, until the occurrence of a
specified event or events ("TRIGGER EVENT"), (x) are deemed to be transferred
with such Ordinary Shares, (y) are not exercisable and (z) are also issued in
respect of future issuances of Ordinary Shares shall be deemed not to have been
distributed for purposes of this Section 12.3(d) (and no adjustment to the
Conversion Price under this Section 12.3(d) will be required) until the
occurrence of the earliest Trigger Event. If such right or warrant is subject to
subsequent events, upon the occurrence of which such right or warrant shall
become exercisable to purchase different distributed assets, evidences of
indebtedness or other assets, or entitle the

                                       67
<Page>

holder to purchase a different number or amount of the foregoing or to purchase
any of the foregoing at a different purchase price, then the occurrence of each
such event shall be deemed to be the date of issuance and Record Date with
respect to a new right or warrant (and a termination or expiration of the
existing right or warrant without exercise by the holder thereof). In addition,
in the event of any distribution (or deemed distribution) of rights or warrants,
or any Trigger Event or other event (of the type described in the preceding
sentence) with respect thereto, that resulted in an adjustment to the Conversion
Price under this Section 12.3(d):

        (i) in the case of any such rights or warrants which shall all have been
     redeemed or repurchased without exercise by any holders thereof, the
     Conversion Price shall be readjusted upon such final redemption or
     repurchase to give effect to such distribution or Trigger Event, as the
     case may be, as though it were a cash distribution, equal to the per share
     redemption or repurchase price received by a holder of Ordinary Shares with
     respect to such rights or warrants (assuming such holder had retained such
     rights or warrants), made to all holders of Ordinary Shares as of the date
     of such redemption or repurchase; and

       (ii) in the case of such rights or warrants which shall have expired or
     been terminated without exercise, the Conversion Price shall be readjusted
     as if such rights and warrants had never been issued.

               (E)      For purposes of this Section 12.3(d) and
Sections 12.3(a), 12.3(b) and 12.3(c), any dividend or distribution to which
this Section 12.3(d) is applicable that also includes (x) Ordinary Shares, (y) a
subdivision or combination of Ordinary Shares to which Section 12.3(b) applies
or (z) rights or warrants to subscribe for or purchase Ordinary Shares to which
Section 12.3(c) applies (or any combination thereof), shall be deemed instead to
be:

        (i) a dividend or distribution of the evidences of indebtedness, assets,
     shares of capital stock, rights or warrants, other than such Ordinary
     Shares, such subdivision or combination or such rights or warrants to which
     Sections 12.3(a), 12.3(b) and 12.3(c) apply, respectively (and any
     Conversion Price reduction required by this Section 12.3(d) with respect to
     such dividend or distribution shall then be made), immediately followed by

       (ii) a dividend or distribution of such Ordinary Shares, such subdivision
     or combination or such rights or warrants (and any further Conversion Price
     reduction required by Sections 12.3(a), 12.3(b) and 12.3(c) with respect to
     such dividend or distribution shall then be made), except:

          (A)  the Record Date of such dividend or distribution shall be
     substituted as (i) "the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution," "Record Date
     fixed for such determinations" and "Record Date" within the meaning of
     Section 12.3(a), (ii) "the day upon which such subdivision becomes
     effective" and "the day upon which such combination becomes effective"
     within the meaning of Section 12.3(b), and (iii) as "the date fixed for the
     determination of stockholders entitled to receive such rights or warrants,"
     "the Record Date fixed for the

                                       68
<Page>

     determination of the stockholders entitled to receive such rights or
     warrants" and such "Record Date" within the meaning of Section 12.3(c); and

          (B)  any Ordinary Shares included in such dividend or distribution
     shall not be deemed "outstanding at the close of business on the date fixed
     for such determination" within the meaning of Section 12.3(a) and any
     reduction or increase in the number of Ordinary Shares resulting from such
     subdivision or combination shall be disregarded in connection with such
     dividend or distribution.

          (e)  In case the Company shall, at any time or from time to time while
any of the Securities are outstanding, by dividend or otherwise, distribute to
all holders of its outstanding Ordinary Shares, cash (excluding any cash that is
distributed upon a reclassification, change, merger, consolidation, statutory
share exchange, combination, sale or conveyance to which Section 12.4 applies or
as part of a distribution referred to in Section 12.3(d)), in an aggregate
amount that, combined together with:

        (i) the aggregate amount of any other such distributions to all holders
     of outstanding Ordinary Shares made exclusively in cash within the 12
     months preceding the date of payment of such distribution, and in respect
     of which no adjustment pursuant to this Section 12.3(e) has been made; and

       (ii) the aggregate amount of any cash, plus the Fair Market Value of
     other consideration paid in respect of any tender offer or exchange offer
     by the Company or any of its Subsidiaries for all or any portion of the
     Ordinary Shares concluded within the 12 months preceding the date of such
     distribution, and in respect of which no adjustment pursuant to Section
     12.3(f) has been made;

exceeds 10% of the product of the Sale Price of the Ordinary Shares on the
Record Date with respect to such distribution, times the number of Ordinary
Shares outstanding on such date, then, and in each case, immediately after the
close of business on such date, the Conversion Price shall be reduced so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the close of business of such Record Date by a
fraction:

          (A)  the numerator of which shall be equal to the Current Market Price
     on the Record Date, less an amount equal to the quotient of (x) the excess
     of such combined amount over such 10% and (y) the number of Ordinary Shares
     outstanding on the Record Date; and

          (B)  the denominator of which shall be equal to the Current Market
     Price on such date.

          (f)  In case a tender offer or exchange offer made by the Company or
any of its Subsidiaries for all or any portion of the Ordinary Shares shall
expire and such tender offer 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 offer or exchange offer) of
shares tendered) of an aggregate consideration having a Fair Market Value (as
determined by the Board of Directors) that combined together with:

                                       69
<Page>

        (i) the aggregate amount of the cash, plus the Fair Market Value, as of
     the expiration of such tender offer or exchange offer, of any other
     consideration payable in respect of any other tender offers or exchange
     offers, by the Company or any of its Subsidiaries for all or any portion of
     the Ordinary Shares expiring within the 12 months preceding the expiration
     of such tender offer or exchange offer and in respect of which no
     adjustment pursuant to this Section 12.3(f) has been made; and

       (ii) the aggregate amount of any distributions to all holders of Ordinary
     Shares made exclusively in cash within 12 months preceding the expiration
     of such tender offer or exchange offer and in respect of which no
     adjustment pursuant to Section 12.3(e) has been made;

exceeds 10% of the product of the Sale Price of the Ordinary Shares as of the
last time (the "EXPIRATION TIME") tenders or exchanges could have been made
pursuant to such tender offer or exchange offer (as it may be amended), times
the number of Ordinary Shares outstanding (including any tendered or exchanged
shares) on the Expiration Time (such excess above 10%, the "EXCESS AMOUNT"),
then, and in each such case, immediately prior to the opening of business on the
day after the date of the Expiration Time, the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the close of business on the
date of the Expiration Time by a fraction:

          (A)  the numerator of which shall be the (x) the product of (i) the
     number of Ordinary Shares outstanding (including any tendered or exchanged
     shares) at the Expiration Time and (ii) the Current Market Price of the
     Ordinary Shares at the Expiration Time, less (y) the Excess Amount; and

          (B)  the denominator shall be the product of the number of Ordinary
     Shares outstanding (including any tendered or exchanged shares) at the
     Expiration Time and the Current Market Price of the Ordinary Shares at the
     Expiration Time.

          Such reduction (if any) shall become effective immediately prior to
the opening of business on the day following the Expiration Time. In the event
that the Company is obligated to purchase shares pursuant to any such tender
offer or exchange offer, but the Company is permanently prevented by applicable
law from effecting any such purchases or all or a portion of such purchases are
rescinded, the Conversion Price shall again be adjusted to be the Conversion
Price which would then be in effect if such (or such portion of the) tender
offer or exchange offer had not been made. If the application of this Section
12.3(f) to any tender offer or exchange offer would result in an increase in the
Conversion Price, no adjustment shall be made for such tender offer under this
Section 12.3(f).

          Pursuant to rights issued under any of the Company's rights plans, if
Holders of the Securities exercising the right of conversion attaching after the
date the rights separate from the underlying Ordinary Shares are not entitled to
receive the rights that would otherwise be attributable to the Ordinary Shares
received upon conversion, the Conversion Price will be adjusted as though the
rights were being distributed to holders of Ordinary Shares on the date of such
separation. If such an adjustment is made and the rights are later redeemed,
invalidated or

                                       70
<Page>

terminated, then a corresponding reversing adjustment will be made to the
Conversion Price on an equitable basis.

          (g)  For purposes of this Article XII, the following terms shall have
the meanings indicated:

          "CURRENT MARKET PRICE" on any date means the average of the daily Sale
Prices per share of Ordinary Shares for the ten consecutive Trading Days
immediately prior to such date; PROVIDED, HOWEVER, that if:

        (i) the "ex" date (as hereinafter defined) for any event (other than the
     issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c),
     (d), (e), or (f) occurs during such ten consecutive Trading Days, the Sale
     Price for each Trading Day prior to the "ex" date for such other event
     shall be adjusted by dividing such Sale Price by the same fraction by which
     the Conversion Price is so required to be adjusted as a result of such
     other event;

        (ii) the "ex" date for any event (other than the issuance or
     distribution requiring such computation) that requires an adjustment to the
     Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e), or (f)
     occurs on or after the "ex" date for the issuance or distribution requiring
     such computation and prior to the day in question, the Sale Price for each
     Trading Day on and after the "ex" date for such other event shall be
     adjusted by dividing such Sale Price by the reciprocal of the fraction by
     which the Conversion Price is so required to be adjusted as a result of
     such other event; and

      (iii) the "ex" date for the issuance or distribution requiring such
     computation is prior to the day in question, after taking into account any
     adjustment required pursuant to clause (1) or (2) of this proviso, the Sale
     Price for each Trading Day on or after such "ex" date shall be adjusted by
     adding thereto the amount of any cash and the Fair Market Value (as
     determined by the Board of Directors in a manner consistent with any
     determination of such value for purposes of Section 12.3(d), (e) or (f) of
     the evidences of Indebtedness, shares of capital stock or assets being
     distributed applicable to one share of Ordinary Shares as of the close of
     business on the day before such "ex" date.

For purposes of any computation under Section 12.3(f), if the "ex" date for any
event (other than the tender offer requiring such computation) that requires an
adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d),
(e) or (f) occurs on or after the Expiration Time for the tender or exchange
offer requiring such computation and prior to the day in question, the Sale
Price for each Trading Day on and after the "ex" date for such other event shall
be adjusted by dividing such Sale Price by the reciprocal of the fraction by
which the Conversion Price is so required to be adjusted as a result of such
other event. For purposes of this paragraph, the term "ex" date, when used:

        (i) with respect to any issuance or distribution, means the first date
     on which the Ordinary Shares trade regular way on the relevant exchange or
     in the relevant market from which the Sale Price was obtained without the
     right to receive such issuance or distribution;

                                       71
<Page>

       (ii) with respect to any subdivision or combination of Ordinary Shares,
     means the first date on which the Ordinary Shares trade regular way on such
     exchange or in such market after the time at which such subdivision or
     combination becomes effective; and

      (iii) with respect to any tender offer or exchange offer, means the
     first date on which the Ordinary Shares trade regular way on such exchange
     or in such market after the Expiration Time of such offer.

Notwithstanding the foregoing, whenever successive adjustments to the Conversion
Price are called for pursuant to this Section 12.3, such adjustments shall be
made to the Current Market Price as may be necessary or appropriate to
effectuate the intent of this Section 12.3 and to avoid unjust or inequitable
results as determined in good faith by the Board of Directors.

          "FAIR MARKET VALUE" means the amount which a willing buyer would pay a
willing seller in an arm's length transaction (as determined by the Board of
Directors, whose determination shall be conclusive).

          "RECORD DATE" means, with respect to any dividend, distribution or
other transaction or event in which the holders of Ordinary Shares have the
right to receive any cash, securities or other property or in which the Ordinary
Shares (or other applicable security) is exchanged for or converted into any
combination of cash, securities or other property, the date fixed for
determination of shareholders entitled to receive such cash, securities or other
property (whether such date is fixed by the Board of Directors or by statute,
contract or otherwise).

          (h)  The Company shall be entitled to make such additional reductions
in the Conversion Price, in addition to those required by Sections 12.3(a), (b),
(c), (d), (e) and (f), as shall be necessary in order that any dividend or
distribution of Ordinary Shares, any subdivision, reclassification or
combination of Ordinary Shares or any issuance of rights or warrants referred to
above shall not be taxable to the holders of Ordinary Shares for United States
Federal income tax purposes.

          (i)  To the extent permitted by applicable law, the Company may, from
time to time, reduce the Conversion Price by any amount for any period of time
if such period is at least 20 days, the reduction is irrevocable during the
period and the Board of Directors determines that such reduction would be in the
best interest of the Company. Whenever the Conversion Price is reduced pursuant
to the preceding sentence, the Company shall mail to the Trustee and each Holder
at the address of such Holder as it appears in the register of the Securities
maintained by the Registrar, at least 15 days prior to the date the reduced
Conversion Price takes effect, a notice of the reduction stating the reduced
Conversion Price and the period during which it will be in effect.

          (j)  In any case in which this Section 12.3 shall require that any
adjustment be made effective as of or retroactively immediately following a
Record Date, the Company may elect to defer (but only for five Trading Days
following the filing of the notice referred to in Section 12.5) issuing to the
Holder of any Securities converted after such Record Date the Ordinary Shares
issuable upon such conversion over and above the Ordinary Shares issuable upon
such conversion on the basis of the Conversion Price prior to adjustment;
PROVIDED,

                                       72
<Page>

HOWEVER, that the Company shall deliver to such Holder a due bill or other
appropriate instrument evidencing such Holder's right to receive such additional
Ordinary Shares upon the occurrence of the event requiring such adjustment.

          (k)  All calculations under this Section 12.3 shall be made to the
nearest cent or one-hundredth of a share, with one-half cent and 0.005 of a
share, respectively, being rounded upward. Notwithstanding any other provision
of this Section 12.3, the Company shall not be required to make any adjustment
of the Conversion Price unless such adjustment would require an increase or
decrease of at least 1% of such price. Any lesser adjustment shall be carried
forward and shall be made at the time of and together with the next subsequent
adjustment which, together with any adjustment or adjustments so carried
forward, shall amount to an increase or decrease of at least 1% in such price.
Any adjustments under this Section 12.3 shall be made successively whenever an
event requiring such an adjustment occurs.

          (l)  In the event that at any time, as a result of an adjustment made
pursuant to this Section 12.3, the Holder of any Securities thereafter
surrendered for conversion shall become entitled to receive any shares of stock
of the Company other than Ordinary Shares into which the Securities originally
were convertible, the Conversion Price of such other shares so receivable upon
conversion of any such Security shall be subject to adjustment from time to time
in a manner and on terms as nearly equivalent as practicable to the provisions
with respect to Ordinary Shares contained in subparagraphs (a) through (k) of
this Section 12.3, and the provision of Sections 12.1, 12.2 and 12.4 through
12.9 with respect to the Ordinary Shares shall apply on like or similar terms to
any such other shares and the determination of the Board of Directors as to any
such adjustment shall be conclusive.

          (m)  No adjustment shall be made pursuant to this Section 12.3 if (i)
the effect thereof would be to reduce the Conversion Price below the par value
(if any) of the Ordinary Shares or (ii) any dividend, distribution or issuance
that would otherwise give rise to an adjustment pursuant to this Section 12.3 is
made or paid to the Holders of the Securities.

          SECTION 12.4. CONSOLIDATION OR MERGER OF THE COMPANY.

     If any of the following events occurs, namely:

          (a)  any reclassification or change of the outstanding Ordinary Shares
     (other than a change in par value, or from par value to no par value, or
     from no par value to par value, or as a result of a subdivision or
     combination);

          (b)  any merger, consolidation, statutory share exchange or
     combination of the Company with another corporation as a result of which
     holders of Ordinary Shares shall be entitled to receive stock, securities
     or other property or assets (including cash) with respect to or in exchange
     for such Ordinary Shares; or

          (c)  any sale or conveyance of the properties and assets of the
     Company as, or substantially as, an entirety to any other corporation as a
     result of which holders of Ordinary Shares shall be entitled to receive
     stock, securities or other property or assets (including cash) with respect
     to or in exchange for such Ordinary Shares;

                                       73
<Page>

the Company or the successor or purchasing corporation, as the case may be,
shall execute with the Trustee a supplemental indenture (which shall comply with
the Trust Indenture Act as in force at the date of execution of such
supplemental indenture, if such supplemental indenture is then required to so
comply) providing that such Securities shall be convertible into the kind and
amount of shares of stock and other securities or property or assets (including
cash) which such Holder would have been entitled to receive upon such
reclassification, change, merger, consolidation, statutory share exchange,
combination, sale or conveyance had such Securities been converted into Ordinary
Shares immediately prior to such reclassification, change, merger,
consolidation, statutory share exchange, combination, sale or conveyance
assuming such holder of Ordinary Shares did not exercise its rights of election,
if any, as to the kind or amount of securities, cash or other property
receivable upon such merger, consolidation, statutory share exchange, sale or
conveyance (PROVIDED, that if the kind or amount of securities, cash or other
property receivable upon such merger, consolidation, statutory share exchange,
sale or conveyance is not the same for each share of Ordinary Shares in respect
of which such rights of election shall not have been exercised ("NON-ELECTING
SHARE"), then for the purposes of this Section 12.4, the kind and amount of
securities, cash or other property receivable upon such merger, consolidation,
statutory share exchange, sale or conveyance for 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). Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article XII. If, in the case of any such
reclassification, change, merger, consolidation, statutory share exchange,
combination, sale or conveyance, the stock or other securities and assets
receivable thereupon by a holder of Ordinary Shares includes shares of stock or
other securities and assets of a corporation other than the successor or
purchasing corporation, as the case may be, in such reclassification, change,
merger, consolidation, statutory share exchange, combination, sale or
conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the Holders of the Securities as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the
extent practicable the provisions providing for the Change of Control repurchase
rights set forth in Article V.

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder, at the address of such Holder as it
appears on the register of the Securities maintained by the Registrar, within 20
days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

          The above provisions of this Section 12.4 shall similarly apply to
successive reclassifications, mergers, consolidations, statutory share
exchanges, combinations, sales and conveyances.

          If this Section 12.4 applies to any event or occurrence, Section 12.3
shall not apply.

          SECTION 12.5. NOTICE OF ADJUSTMENT.

          Whenever an adjustment in the Conversion Price with respect to the
Securities is required:

                                       74
<Page>

          (a)  the Company shall forthwith place on file with the Trustee and
     any Conversion Agent for such securities a certificate of the Treasurer of
     the Company, stating the adjusted Conversion Price determined as provided
     herein and setting forth in reasonable detail such facts as shall be
     necessary to show the reason for and the manner of computing such
     adjustment; and

          (b)  a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be given by the
     Company or, at the Company's request, by the Trustee in the name and at the
     expense of the Company, to each Holder in the manner provided in Section
     13.2. Any notice so given shall be conclusively presumed to have been duly
     given, whether or not the Holder receives such notice.

          SECTION 12.6. NOTICE IN CERTAIN EVENTS.

          In case of:

          (a)  a consolidation or merger to which the Company is a party and for
     which approval of any shareholders of the Company is required, or of the
     sale or conveyance to another Person or entity or group of Persons or
     entities acting in concert as a partnership, limited partnership, syndicate
     or other group (within the meaning of Rule 13d-3 under the Exchange Act) of
     all or substantially all of the property and assets of the Company; or

          (b)  the voluntary or involuntary dissolution, liquidation or winding
     up of the Company; or

          (c)  any action triggering an adjustment of the Conversion Price
     referred to in clauses (x) or (y) below;

then, in each case, the Company shall cause to be filed with the Trustee and the
Conversion Agent, and shall cause to be given, to the Holders of the Securities
in the manner provided in Section 13.2, at least 15 days prior to the applicable
date hereinafter specified, a notice stating:

          (x)  the date on which a record is to be taken for the purpose of any
     distribution or grant of rights or warrants triggering an adjustment to the
     Conversion Price pursuant to this Article XII, or, if a record is not to be
     taken, the date as of which the holders of record of Ordinary Shares
     entitled to such distribution, rights or warrants are to be determined; or

          (y)  the date on which any reclassification, consolidation, merger,
     sale, conveyance, dissolution, liquidation or winding up triggering an
     adjustment to the Conversion Price pursuant to this Article XII is expected
     to become effective, and the date as of which it is expected that holders
     of Ordinary Shares of record shall be entitled to exchange their Ordinary
     Shares for securities or other property deliverable upon such
     reclassification, consolidation, merger sale, conveyance, dissolution,
     liquidation or winding up.

                                       75
<Page>

          Failure to give such notice or any defect therein shall not affect the
legality or validity of the proceedings described in clause (a), (b) or (c) of
this Section 12.6.

          SECTION 12.7. COMPANY TO RESERVE STOCK: REGISTRATION; LISTING.

          (a)  The Company shall, prior to issuance of any Securities hereunder,
and from time to time as may be necessary, reserve and keep available, free from
preemptive rights, out of its authorized but unissued Ordinary Shares, for the
purpose of effecting the conversion of the Securities, such number of its duly
authorized Ordinary Shares as shall from time to time be sufficient to effect
the conversion of all Securities then outstanding into such Ordinary Shares at
any time (assuming that, at the time of the computation of such number of
Ordinary Shares, all such Securities would be held by a single Holder). The
Company covenants that all Ordinary Shares which may be issued upon conversion
of Securities will upon issue be fully paid and nonassessable and free from all
liens and charges and, except as provided in Section 12.8, taxes with respect to
the issue thereof.

          (b)  If any Ordinary Shares which would be issuable upon conversion of
Securities hereunder require registration with or approval of any governmental
authority before such shares or securities may be issued upon such conversion,
the Company will use its reasonable best efforts to cause such shares or
securities to be duly registered or approved, as the case may be. The Company
further covenants that so long as the Ordinary Shares shall be listed on the
NYSE, the Company will use its reasonable best efforts, if permitted by the
rules of the NYSE, to list and keep listed all Ordinary Shares issuable upon
conversion of the Securities, and the Company will use its reasonable best
efforts to list the Ordinary Shares to be delivered upon conversion of the
Securities prior to such delivery upon any other national securities exchange
upon which the outstanding Ordinary Shares is listed at the time of such
delivery.

          SECTION 12.8. TAXES ON CONVERSION.

          The issue of stock certificates on conversion of Securities shall be
made without charge to the converting Holder for any documentary, stamp or
similar issue or transfer taxes in respect of the issue thereof, and the Company
shall pay any and all documentary, stamp or similar issue or transfer taxes that
may be payable in respect of the issue or delivery of Ordinary Shares on
conversion of Securities pursuant hereto. The Company shall not, however, be
required to pay any such tax which may be payable in respect of any transfer
involved in the issue or delivery of Ordinary Shares or the portion, if any, of
the Securities which are not so converted in a name other than that in which the
Securities so converted were registered, and no such issue or delivery shall be
made unless and until the Person requesting such issue has paid to the Company
the amount of such tax or has established to the satisfaction of the Company
that such tax has been paid.

          SECTION 12.9. CONVERSION AFTER REGULAR RECORD DATE.

          Except as provided in the succeeding paragraph, the Holder of such
Securities shall not be entitled to receive any accrued and unpaid interest or
Additional Amounts, if any.

          If any Securities are surrendered for conversion subsequent to the
close of business on any Regular Record Date but prior to the opening of
business on the corresponding

Interest Payment Date, the Holder of such Securities at the close of business on
such Regular Record Date shall receive the interest and Additional Amounts, if
any, payable on such Securities on such Interest Payment Date notwithstanding
the conversion thereof. Securities surrendered for conversion during the period
from the close of business on any Regular Record Date to the opening of business
on the corresponding Interest Payment Date shall (except in the case of
Securities which have been called for redemption on a Redemption Date within
such period) be accompanied by payment by Holders, for the account of the
Company, in New York Clearing House funds or other funds acceptable to the
Company of an amount equal to the interest and Additional Amounts, if any,
payable on such interest payment date on the Securities being surrendered for
conversion.

          Except as provided in this Section 12.9, no payment or adjustment
shall be made in respect of dividends or distributions on the Ordinary Shares
issued upon conversion or accrued and unpaid interest or Additional Amounts, if
any, on a converted Security.

          SECTION 12.10. COMPANY DETERMINATION FINAL.

          Any determination that the Company or the Board of Directors must make
pursuant to this Article XII shall be conclusive if made in good faith and in
accordance with the provisions of this Article, absent manifest error, and set
forth in a Board Resolution.

          SECTION 12.11. RESPONSIBILITY OF TRUSTEE FOR CONVERSION PROVISIONS.

          The Trustee has no duty to determine when an adjustment under this
Article XII should be made, how it should be made or what it should be. The
Trustee makes no representation as to the validity or value of any securities or
assets issued upon conversion of Securities. The Trustee shall not be
responsible for any failure of the Company to comply with this Article XII. Each
Conversion Agent other than the Company shall have the same protection under
this Section 12.11 as the Trustee.

          The rights, privileges, protections, immunities and benefits given to
the Trustee under the Indenture including, without limitation, its rights to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each Paying Agent or Conversion Agent acting
hereunder.

          SECTION 12.12. UNCONDITIONAL RIGHT OF HOLDERS TO CONVERT.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
convert its Security in accordance with this Article XII and to bring an action
for the enforcement of any such right to convert, and such rights shall not be
impaired or affected without the consent of such Holder.

          SECTION 12.13. CASH CONVERSION OPTION.

          (a)  If a Holder elects to convert all or any portion of a Security
into Ordinary Shares pursuant to Section 12.1, the Company may choose to satisfy
all or any portion of its conversion obligation (the "CONVERSION OBLIGATION") in
cash. Upon such election, the Company will notify such Holder through the
Trustee of the dollar amount to be satisfied in cash

                                       77
<Page>

(which must be expressed either as a percentage of the Conversion Obligation or
as a fixed dollar amount) at any time on or before the date that is two Business
Days following receipt of the Conversion Notice required pursuant to Section
12.2 (such period, the "CASH SETTLEMENT NOTICE PERIOD"). If the Company elects
to pay cash for any portion of the Ordinary Shares otherwise issuable to the
Holder, the Holder may retract the conversion notice at any time during the two
Business Day period beginning on the day after the final day of the Cash
Settlement Notice Period (a "CONVERSION RETRACTION PERIOD"); no such retraction
can be made (and a Conversion Notice shall be irrevocable) if the Company does
not elect to deliver cash in lieu of shares (other than cash in lieu of
fractional shares). If the Conversion Notice has not been retracted, then
settlement (in cash and/or Ordinary Shares) will occur on the Business Day
following the final day of the 20 Trading Day period beginning on the day after
the final day of the Conversion Retraction Period (the "CASH SETTLEMENT
AVERAGING PERIOD"). Settlement amounts will be computed as follows:

               (i)      if the Company elects to satisfy the entire Conversion
     Obligation in Ordinary Shares, the Company will deliver to such Holder a
     number of Ordinary Shares equal to (1) the aggregate original principal
     amount of Securities to be converted divided by 1,000, multiplied by (2)
     the Conversion Rate;

               (ii)     if the Company elects to satisfy the entire Conversion
     Obligation in cash, the Company will deliver to such Holder cash in an
     amount equal to the product of:

                        (1)     a number equal to (x) the aggregate original
          principal amount of Securities to be converted divided by 1,000,
          multiplied by (y) the Conversion Rate, and

                        (2)     the average Sale Price of the Ordinary Shares
          during the Cash Settlement Averaging Period; and

               (iii)    if the Company elects to satisfy a portion of the
     Conversion Obligation in cash (the "CASH AMOUNT"), the Company will deliver
     to such Holder the Cash Amount and a number of Ordinary Shares equal to (1)
     the number of Ordinary Shares calculated in clause (i) above, minus (2) the
     quotient of the Cash Amount divided by the average of the Sale Price of the
     Ordinary Shares over the Cash Settlement Averaging Period.

Notwithstanding the foregoing, a Security in respect of which a Holder has
delivered a Repurchase Notice or a Change of Control Repurchase Notice, as the
case may be, exercising such Holder's right to require the Company to repurchase
such Security may be converted as described in this Section 12.13(a) only if
such notice of exercise is withdrawn in accordance with the Section 4.3 or 5.3,
as applicable, prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the applicable Repurchase Date or Change of Control
Repurchase date, as the case may be.

          (b)  If a Holder elects to convert all or any portion of a Security
into Ordinary Shares after the Company has exercised its right to redeem all or
any portion of the Securities

                                       78
<Page>

pursuant to Section 5 of the Securities or within 20 days of the Stated
Maturity, the Company may choose to satisfy all or any portion of the Conversion
Obligation in cash provided the Company notifies such Holder through the Trustee
of the dollar amount to be satisfied in cash (which must be expressed either as
100% of the Conversion Obligation or as a fixed dollar amount) at any time on or
before the date that is 20 days prior to Stated Maturity or Redemption Date.
Settlement amounts will be computed in the same manner as set forth in (a) above
except that the "Cash Settlement Averaging Period" shall be the 20 Trading Day
period beginning on the day after the Stated Maturity or Redemption Date, as the
case may be. Settlement (in cash and/or shares) will occur on the Business Day
following the final day of such Cash Settlement Averaging Period.

          (c)  The Company shall elect to satisfy in cash any Conversion
Obligation with respect to a Holder that does not certify on its Conversion
Notice that neither it nor any other Person shall become a 10% Shareholder if
the Company satisfies such Conversion Obligation entirely in Ordinary Shares.

SCOTTISH ANNUITY & LIFE HOLDINGS, LTD., a Cayman Islands exempted company (the
"Company", which term shall include any successor corporation under the
Indenture referred to on the reverse hereof) promises to pay to
_____________________, or registered assigns, the principal amount of
_______________ Dollars ($_________) [, or such greater or lesser amount as is
indicated in the records of the Trustee and the Depositary,](3) on December 1,
2022, and to pay interest thereon from November 22, 2002 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, on
June 1 and December 1 in each year (each, an "Interest Payment Date"),
commencing on June 1, 2003, at the rate of 4.50% per annum, until the principal
hereof is paid or made available for payment at December 1, 2022 or upon
acceleration, or until such date on which the Securities are converted, redeemed
or repurchased as provided herein, and at the rate of 4.50% per annum on any
overdue principal and on any overdue installment of interest and Additional
Amounts, if any. The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture (as
hereinafter defined), be paid to the Person in whose name this Security (or one
or more predecessor Securities) is registered at the close of business on the
regular record date for such interest, which will be the May 15 or November 15
(whether or not a Business Day), as the case may be, next preceding the
corresponding Interest Payment Date (a "Regular Record Date"). Any such interest
and Additional Amounts, if any, not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
be paid (a) to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a special
record date for the payment of such defaulted interest to be fixed by the
Trustee (a "Special Record Date"), notice whereof will be given to Holders not
less than 10 calendar days prior to such Special Record Date, or (b) at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

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

Securities or portions thereof. Securities in denominations larger than $1,000

Indenture.

          Holders have the right to withdraw any Repurchase Notice or Change of
Control Repurchase Notice by delivering to the Paying Agent a written notice of
withdrawal in accordance with the provisions of the Indenture.

          If cash and/or Applicable Stock, if permitted under the Indenture, is
sufficient to pay the Repurchase Price or Change of Control Repurchase Price, as
the case may be, of all Securities or portions thereof to be repurchased on the
Repurchase Date or the Change of Control Repurchase Date, as the case may be, is
deposited with the Paying Agent, at 10:00 a.m., New York City time, on the
Repurchase Date or the Change of Control Repurchase Date, as the case may be,
such Securities will cease to be outstanding and interest and Additional
Amounts, if any, on such Securities will cease to accrue and the Holder thereof
shall have no other rights as such other than the right to receive the
Repurchase Price or Change of Control Repurchase Price upon surrender of such
Security.

12.13 thereof, fully paid and nonassessable shares of Ordinary Shares at the
Conversion Price in effect on the date of conversion.

          The Company will notify Holders of any event triggering the right to
convert the Securities as specified above in accordance with the Indenture.

                                      A - 8
<Page>

          A Security in respect of which a Holder has delivered a Repurchase
Notice or Change of Control Repurchase Notice, as the case may be, exercising
the right of such Holder to require the Company to repurchase such Security may
be converted only if such Repurchase Notice or Change of Control Repurchase
Notice is withdrawn in accordance with the terms of the Indenture.

          The initial Conversion Price is $21.71, subject to adjustment in
certain events described in the Indenture.

          To surrender a Security for conversion, a Holder must, in the case of
Global Securities, comply with the Applicable Procedures of the Depositary in
effect at that time, and in the case of Certificated Securities, (1) surrender
the Security to the Conversion Agent, (2) complete and manually sign the
conversion notice below (or complete and manually sign a facsimile of such
notice) and deliver such notice to the Conversion Agent, (3) furnish appropriate
endorsements and transfer documents and (4) pay all funds required, if any,
relating to interest or Additional Amounts, if any, and any transfer or similar
tax, if required.

          No fractional Ordinary Share shall be issued upon conversion of any
Security. Instead, the Company shall pay a cash adjustment as provided in the
Indenture.

          No payment or adjustment will be made for accrued and unpaid interest
and Additional Amounts, if any, or dividends on the Ordinary Shares, except as
provided in the Indenture.

          Upon conversion, the Company may choose to deliver, in lieu of
Ordinary Shares, cash or a combination of cash and Ordinary Shares in accordance
with the Indenture.

          If the Company (i) is a party to a consolidation, merger or binding
share exchange (ii) reclassifies the Ordinary Shares or (iii) conveys, transfers
or leases its properties and assets substantially as an entirety to any Person,
the right to convert a Security into shares of Ordinary Shares may be changed
into a right to convert it into securities, cash or other assets of the Company
or such other Person, in each case in accordance with the Indenture.

8.   DENOMINATIONS; TRANSFER; EXCHANGE.

          The Securities are in fully registered form, without coupons, in
denominations of $1,000 of principal amount and integral multiples of $1,000. A
Holder may transfer or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not transfer or exchange
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities in respect of which a Repurchase Notice or Change of Control
Repurchase Notice has been given and not withdrawn (except, in the case of a
Security to be repurchased in part, the portion of the Security not to be
repurchased) or any Securities for a period of 15 days before the mailing of a
notice of redemption of Securities to be redeemed.

material respect, (viii) cure any ambiguity, correct or supplement any provision
