insofar as it relates to legal matters, upon a certificate or opinion of, or

originally received in the corrected form and, irrespective of the date or dates
of the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Without limiting the generality of the foregoing, any Securities
issued under the authority of such defective document or instrument shall
nevertheless be the valid obligations of the Company entitled to the benefits of
this Indenture equally and ratably with all other Outstanding Securities.

      SECTION 1.4. Acts of Holders.

      (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given to or taken by Holders

appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments (including any
appointment of an agent) is or are delivered to the Trustee, and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Holders

                                       10
<PAGE>
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section 1.4.

      (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him or her the execution thereof.
Where such execution is by a Person acting in other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution by any Person of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner that the Trustee deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

      (c) The ownership of Securities shall be proved by the Securities
Register.

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

      (e) Without limiting the foregoing, a Holder entitled to take any action
hereunder with regard to any particular Security may do so with regard to all or
any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

      (f) Except as set forth in paragraph (g) of this Section 1.4, the Company
may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities entitled to give, make or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Indenture to be given, made or taken by Holders of Securities.
If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take
the relevant action, whether or not such Holders remain Holders after such
record date; provided, that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date (as defined in Section
1.4(h)) by Holders of the requisite principal amount of Outstanding Securities
on such record date. Nothing in this paragraph shall be construed to prevent the
Company from setting a new record date for any action for which a record date
has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be canceled
and of no effect). Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities in the manner
set forth in Section 1.6.

      (g) The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration or
rescission or annulment thereof referred to in Section 5.2, (iii) any request to
institute proceedings referred to in Section 5.7(b) or (iv) any

                                       11
<PAGE>
direction referred to in Section 5.12. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities on such record date, and
no other Holders, shall be entitled to join in such notice, declaration, request
or direction, whether or not such Holders remain Holders after such record date;
provided, that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities on such record date. Nothing in this paragraph
shall be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect). Promptly after any record
date is set pursuant to this paragraph, the Trustee, at the Company's expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities in the manner set forth in Section 1.6.

      (h) With respect to any record date set pursuant to paragraph (f) or (g)
of this Section 1.4, the party hereto that sets such record date may designate
any day as the "Expiration Date" and from time to time may change the Expiration
Date to any earlier or later day; provided, that no such change shall be
effective unless notice of the proposed new Expiration Date is given to the
other party hereto in writing, and to each Holder of Securities in the manner
set forth in Section 1.6, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section 1.4, the party hereto that set such record date shall be deemed
to have initially designated the ninetieth (90th) day after such record date as
the Expiration Date with respect thereto, subject to its right to change the
Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no
Expiration Date shall be later than the one hundred eightieth (180th) day after
the applicable record date.

      SECTION 1.5. Notices, Etc. to Trustee and Company.

      Any request, demand, authorization, direction, notice, consent, waiver,
Act of Holders, or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with:

purpose hereunder if made, given, furnished or filed in writing to or with and
received by the Trustee at its Corporate Trust Office, or

      (b) the Company by the Trustee or any Holder shall be sufficient for every
purpose hereunder if in writing and mailed, first class, postage prepaid, to the

class, postage prepaid, to each Holder affected by such event to the address of
such Holder as it appears in the Securities Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice. If, by reason of the suspension of or irregularities in regular mail
service or for any other reason, it shall be impossible or impracticable to mail
notice of any event to Holders when said notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice. In any case where notice to Holders is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      SECTION 1.7. Effect of Headings and Table of Contents.

      If any provision in this Indenture or in the Securities shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby, and
there shall be deemed substituted for the provision at issue a valid, legal and
enforceable provision as similar as possible to the provision at issue.

      SECTION 1.10. Benefits of Indenture.

      Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors and
assigns, the holders of Senior Debt, the Holders of the Securities and any
benefit or any legal or equitable right, remedy or claim under this Indenture.

the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, through but excluding such next succeeding

accepting a Security waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Securities.

      SECTION 1.15. Agent for Service of Process.

      The Company will designate and appoint CT Corporation System in New York
City as its process agent (the "Process Agent") upon which process may be served
in any action arising out of or relating to this Indenture which may be
instituted in any New York Court by the Trustee or the Holders, in accordance
with legal procedures prescribed for such courts within fifteen (15) days of
execution of the Indenture by the parties hereto, and will expressly consent to
the non-exclusive jurisdiction of any such court in respect of any such action,
and waive any other requirements of or objections to personal jurisdiction with
respect thereto. Such appointment

                                       14
<PAGE>

shall be irrevocable. Service of process upon the Process Agent and written
notice of such service of process to it shall be deemed, in every respect,
effective service of process upon the Company. Nothing herein shall in any way
be deemed to limit the ability of the Trustee or the Holders to serve any such
legal process, summons, notices and documents in any other manner permitted by
applicable law or to obtain jurisdiction over the Company or to bring actions,
suits or proceedings against the Company in such other jurisdictions, and in
such manner, as may be permitted by applicable law.

      SECTION 1.16. Currency Indemnity.

      If, for the purposes of obtaining judgment in any court in any
jurisdiction with respect to any payment due hereunder, it becomes necessary to
convert into the currency of such jurisdiction (the "Judgment Currency") any
amount due hereunder in any currency other than the Judgment Currency (the
"Currency Due"), then conversion shall be made at the rate of exchange
prevailing on the Business Day before the day on which judgment is given. For
this purpose, "rate of exchange" means the rate at which the Trustee is able, on
the relevant date, to purchase the Currency Due with the Judgment Currency in
accordance with its normal practice. In the event that there is a change in the
rate of exchange prevailing between the Business Day before the day on which the
judgment is given and the date of payment of the amount due, the Company will,
on the day of payment, pay such additional amount, if any, or be entitled to
receive reimbursement of such amount, if any, as may be necessary to ensure that
the amount paid on such date is the amount in the Judgment Currency which when
converted at the rate of exchange prevailing on the date of payment is the
amount then due hereunder in the Currency Due. If the amount of the Currency Due
which the Trustee would be able to purchase at such rate of exchange is less
than the amount of the Currency Due originally due to it, the Company shall
indemnify and save the Trustee and the Holders harmless from and against loss or
damage arising as a result of such deficiency. If the amount of the Currency Due
which the Trustee would be able to purchase at such rate of exchange is greater
than the amount of the Currency Due originally due to it, the Trustee shall
promptly pay to the Company in U.S. dollars an amount equal to such excess. This
indemnity shall constitute an obligation separate and independent from the other
obligations contained herein, shall give rise to a separate and independent
cause of action and shall continue in full force and effect notwithstanding any
judgment or order for a liquidated sum in respect of an amount due hereunder or
under any judgment or order.

                                 SECURITY FORMS

      SECTION 2.1. Form of Security.

      Any Security issued hereunder shall be in substantially the following
form:

<PAGE>

      Validus Holdings, Ltd., a company with limited liability organized under
the laws of Bermuda (hereinafter called the "Company," which term includes any
successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to [        ], or registered assigns, the
principal sum of [    ] ($[      ]) in accordance with the Indenture on June 15,
2037. The Company further promises to pay interest on said principal sum from
June 21, 2007, or from the most recent Interest Payment Date to which interest
has been paid or duly provided for, quarterly (subject to deferral as set forth
herein) in arrears on March 15, June15, September 15 and December 15 of each
year, commencing September 15, 2007, or if any such day is not a Business Day,
on the next succeeding Business Day (and additional interest shall accrue in
respect of the amounts whose payment is so delayed for the period from and after
such Interest Payment Date through but excluding such next succeeding Business
Day), except that, if such Business Day falls in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case, with the same force and effect as if made on the Interest Payment
Date, at a fixed rate equal to 8.48% per annum through but excluding June 15,
2012 and thereafter at a variable rate equal to LIBOR plus 2.95% per annum,
together with Additional Amounts, if any, as provided in Section 10.5 of the
Indenture, until the principal hereof is paid or duly provided for or made
available for payment; provided, further, that any overdue principal, premium,
if any, or Additional Amounts and any overdue installment of interest shall bear
Additional Interest at a fixed rate equal to 8.48% through but excluding June
15, 2012 and thereafter at a variable rate equal to LIBOR plus 2.95% per annum;
(to the extent that the payment of such interest shall be legally enforceable),
compounded quarterly, from the dates such amounts are due until they are paid or
made available for payment, and such interest shall be payable on demand,
provided further that during the Fixed Rate Period if any Interest Payment Date
shall not be a Business Day, and payment of interest, premium, or principal or
other amounts are made on the next succeeding Business Day, additional interest
shall not accrue in respect of the amounts whose payment is so delayed for the
period from and after such Interest Payment Date through but excluding such next
succeeding Business Day.

      The amount of interest payable for any interest period shall be computed
and paid (i) during the Fixed Rate Period on the basis of a 360-day year of
twelve 30-day months and (ii) thereafter on the basis of a 360-day year and the
actual number of days elapsed in the relevant interest period. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
shall, as provided in the Indenture, 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 installment. Any such
interest not so punctually paid or duly provided for shall forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid 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, notice whereof shall be
given to Holders of Securities not less than ten (10) days prior to such Special
Record Date, or be paid 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.

      So long as no Event of Default has occurred and is continuing, the Company
shall have the right, at any time and from time to time during the term of this
Security, to defer the payment of interest on this Security for a period of up
to twenty (20) consecutive quarterly interest payment periods (each such period,
an "Extension Period"), during which Extension Period(s),

                                       16
<PAGE>
no interest shall be due and payable (except any Additional Amounts that may be
due and payable). No Extension Period shall end on a date other than an Interest
Payment Date, and no Extension Period shall extend beyond the Stated Maturity of
the principal of this Security. No interest shall be due and payable during an
Extension Period (except any Additional Amounts that may be due and payable),
except at the end thereof, but each installment of interest that would otherwise
have been due and payable during such Extension Period shall bear Additional
Interest (to the extent payment of such interest would be legally enforceable)
at a fixed rate equal to 8.48% per annum through but excluding June 15, 2012 and
thereafter at a variable rate equal to LIBOR plus 2.95% per annum; compounded
quarterly, from the dates on which amounts would have otherwise been due and
payable until paid or made available for payment. At the end of any such
Extension Period, the Company shall pay all interest then accrued and unpaid on
this Security, together with such Additional Interest to Holders of record of
this Security as of the record date established for the Interest Payment Date
coinciding with the end of such Extension Period (regardless of who the Holders
of record may have been on any date during such Extension Period). Prior to the
termination of any such Extension Period, the Company may further defer the
payment of interest; provided, that (i) all such previous and further extensions
comprising such Extension Period do not exceed twenty (20) consecutive quarterly
interest payment periods, (ii) no Extension Period shall end on a date other
than an Interest Payment Date and (iii) no Extension Period shall extend beyond
the Stated Maturity of the principal of this Security. Upon the termination of
any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due on any Interest Payment Date, the
Company may elect to begin a new Extension Period; provided, that (i) such
Extension Period does not exceed twenty (20) consecutive quarterly interest
payment periods, (ii) no Extension Period shall end on a date other than an
Interest Payment Date and (iii) no Extension Period shall extend beyond the
Stated Maturity of the principal of this Security. The Company shall give the
Holder of this Security and the Trustee written notice of its election to begin
any such Extension Period at least five (5) Business Days prior to the next
succeeding Interest Payment Date on which interest on this Security would be
payable but for such deferral.

      During any such Extension Period, the Company shall not, and shall not
permit any subsidiary of the Company to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Company's or such subsidiary's capital stock (other
than payments of dividends or distributions to the Company) or make any
guarantee payments with respect to the foregoing, (ii) make any payment of
principal of or any interest or premium, if any, on or repay, repurchase or
redeem any debt securities of the Company that rank pari passu in all respects
with or junior in interest to this Security (other than, with respect to clauses
(i) and (ii) above, (a) repurchases, redemptions or other acquisitions of shares
of capital stock of the Company or any subsidiary of the Company in connection
with (1) any employment contract, benefit plan or other similar arrangement with
or for the benefit of any one or more employees, officers, directors or
consultants, (2) a dividend reinvestment or stockholder stock purchase plan
and/or (3) the issuance of capital stock of the Company or of such subsidiary
(or securities convertible into or exercisable for such capital stock) as
consideration in an acquisition transaction entered into prior to the applicable
Extension Period, (b) as a result of an exchange or conversion of any class or
series of the Company's capital stock (or any capital stock of a subsidiary of
the Company) for any class or series of the Company's capital stock (or, in the
case of a subsidiary of the Company, any class or series of such subsidiary's
capital stock)or of any class or series of the Company's indebtedness for any
class or series of the Company's capital stock (or in the case of indebtedness
of a subsidiary of the

                                       17
<PAGE>
Company, of any class or series of such subsidiary's indebtedness for any class
or series of such subsidiary's capital stock), (c) the purchase of fractional
interests in shares of the Company's capital stock (or the capital stock of a
subsidiary of the Company) pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any Rights Plan, the issuance of
rights, stock or other property under any Rights Plan, or the redemption or
repurchase of rights pursuant thereto or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock and any cash payments in lieu of fractional shares issued in
connection therewith or (f) any repurchases, redemptions or other acquisitions
of shares of capital stock of the Company or any subsidiary of the Company made
by the Company or such subsidiary, which the Company's Board of Directors
determine in good faith are necessary or advisable in order to avoid, ameliorate
or limit any material adverse tax or regulatory consequences for the Company or
its shareholders) or (iii) enter into any new (as opposed to existing) contracts
on less than an arm's-length negotiation basis with shareholders holding more
than 10% of the outstanding shares of Common Shares of the Company.

      Payment of principal of, premium, if any, and interest on this Security
shall be made 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.
Payments of principal, premium, if any, and interest due at the Maturity of this
Security shall be made at the Place of Payment upon surrender of such Securities
to the Paying Agent, and payments of interest shall be made, subject to such
surrender where applicable, by wire transfer at such place and to such account
at a banking institution in the United States as may be designated in writing to
the Paying Agent at least ten (10) Business Days prior to the date for payment
by the Person entitled thereto unless proper written transfer instructions have
not been received by the relevant record date, in which case such payments shall
be made by check mailed to the address of such Person as such address shall
appear in the Security Register.

      The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and junior in right of payment to the prior payment
in full of all Senior Debt, and this Security is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this Security,
by accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his or her behalf to take such actions as
may be necessary or appropriate to effectuate the subordination so provided and
(c) appoints the Trustee his or her attorney-in-fact for any and all such
purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice
of the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Debt, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

      Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

                          [FORM OF REVERSE OF SECURITY]

Company (the "Securities") issued under the Junior Subordinated Indenture, dated

"Indenture"), between the Company and Wilmington Trust Company, as Trustee (in
such capacity, the "Trustee," which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee, the
holders of Senior Debt, the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered.

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

      The Company may, on any Interest Payment Date, at its option and in
accordance with the Indenture, on or after June 15, 2012 and subject to the
terms and conditions of Article XI of the Indenture, redeem this Security in
whole at any time or in part from time to time at a Redemption Price equal to

Interest, through but excluding the date fixed as the Redemption Date.

      In addition, upon the occurrence and during the continuation of a Special
Event, the Company may, at its option and in accordance with the Indenture,
redeem this Security, in whole but not in part, subject to the terms and

the Holder hereof upon the cancellation hereof. If less than all the Securities

Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose of modifying in any manner the rights and obligations

principal amount of the Outstanding Securities. The Indenture also contains
provisions permitting Holders of specified percentages in principal amount of
the Securities, on behalf of the Holders of all Securities, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

      No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium, if any, and
interest, including any Additional Interest (to the extent legally enforceable),

office or agency of the Company maintained for such purpose, duly endorsed by,

Company and the Securities Registrar and duly executed by, the Holder hereof or
such Holder's attorney duly authorized in writing, and thereupon one or more new
Securities, of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

      The Securities are issuable only in registered form without coupons in
minimum denominations of $100,000 and any integral multiple of $1,000 in excess
thereof. As provided in the Indenture and subject to certain limitations therein
set forth, Securities are exchangeable for a like aggregate principal amount of
Securities and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

      No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

interest in, this Security agree that, for United States federal, state and
local tax purposes, it is intended that this Security constitute indebtedness.

      ITS PURCHASE AND HOLDING THEREOF THAT IT IS NOT AN EMPLOYEE BENEFIT PLAN
      WITHIN THE MEANING OF SECTION 3(3) OF ERISA, OR A PLAN TO WHICH SECTION
      4975 OF THE CODE IS APPLICABLE, A TRUSTEE OR OTHER PERSON ACTING ON BEHALF
      OF AN EMPLOYEE BENEFIT PLAN OR PLAN, OR ANY OTHER PERSON OR ENTITY USING
      THE ASSETS OF ANY EMPLOYEE BENEFIT PLAN OR PLAN TO FINANCE SUCH PURCHASE.

      INTERESTS THEREIN ARE LIMITED AS SET FORTH IN SECTION 2.6 OF THE
      INDENTURE.

      HOLDERS OF THIS SECURITY AND/OR BENEFICIAL INTERESTS THEREIN ARE SUBJECT

      (b) The above legends shall not be removed from any Security unless there
is delivered to the Company satisfactory evidence, which may include an Opinion
of Counsel, as may be reasonably required to ensure that any future transfers
thereof may be made without restriction under or violation of the provisions of
the Securities Act and other applicable law. Upon provision of such satisfactory
evidence, the Company shall execute and deliver to the Trustee, and the Trustee
shall deliver, upon receipt of a Company Order directing it to do so, a Security
that does not bear the legend.

      SECTION 2.3. Form of Trustee's Certificate of Authentication.

      The Trustee's certificate of authentication shall be in substantially the

      SECTION 2.4. Temporary Securities.

      (a) Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities that are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any 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 evidenced by their execution of such
Securities.

                                       23
<PAGE>
      (b) 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 that purpose 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 one or more definitive Securities of any authorized
denominations having the same Original Issue Date and Stated Maturity and having
the same terms as such temporary Securities. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.

      SECTION 2.5. Definitive Securities.

      The Securities issued on the Original Issue Date shall be in definitive
form. The definitive Securities shall be printed, lithographed or engraved, or
produced by any combination of these methods, if required by any securities
exchange on which the Securities may be listed, on a steel engraved border or
steel engraved borders or may be produced in any other manner permitted by the
rules of any securities exchange on which the Securities may be listed, all as
determined by the officers executing such Securities, as evidenced by their
execution of such Securities.

      SECTION 2.6. Limited Holders.

      Notwithstanding anything contained in this Indenture or the Securities to
the contrary, for until the earlier of (i) June 15, 2012, (ii) the date on which
Standard & Poors ("S&P") issues any public rating on the Company or any
Significant Subsidiary for any reason or (iii) the first date on which the
Company elects to defer interest pursuant to Section 3.9, no Holder may Transfer
its Security or a beneficial interest therein if after giving effect to such
Transfer there would be greater than twenty (20) Holders of the Securities
(and/or of beneficial interests in the Securities) (the "Limited Holder
Restriction") without the prior written consent of the Company ("Limited Holder
Company Consent"), which Limited Holder Company Consent shall not be
unreasonably withheld or delayed; provided, however, that no Limited Holder
Company Consent shall be required if the Transfer of such Security or beneficial
interest in a Security is being made pursuant to the terms of the documents
governing the duties with respect to credit deterioration or substitution of a
collateral manager or trustee of a collateralized debt obligor Holder. The
Company shall notify the Trustee of the occurrence of item (ii) above. Neither
the Trustee nor the Securities Registrar shall be responsible for monitoring
compliance with any of the above limitations; provided, that the Trustee and the
Securities Registrar shall promptly respond to a Company request to identify the
Holders of the Securities. Any Transfer made in violation of the terms of this
Section 2.6 shall be an ineffective Transfer and shall be null and void.

                                   ARTICLE III

                                 THE SECURITIES

      SECTION 3.1. Payment of Principal and Interest.

      (a) The unpaid principal amount of the Securities shall bear interest at a
fixed rate equal to 8.48% per annum through but excluding June 15, 2012 and
thereafter at a variable rate of LIBOR plus 2.95% per annum until paid or duly
provided for; such interest to accrue from June 21, 2007, or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, and any overdue principal, premium, if any, or Additional Amounts and any
overdue installment of interest shall bear Additional Interest at the rate equal
to a fixed rate equal to 8.48% per annum through but excluding June 15, 2012 and
thereafter at a variable rate of LIBOR plus 2.95% per annum; compounded
quarterly from the dates such amounts are due until they are paid or funds for
the payment thereof are made available for payment.

      (b) Interest and Additional Interest on any Security that is payable, and
is punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, except that interest and any Additional Interest payable on
the Stated Maturity (or any date of principal repayment upon early maturity) of
the principal of a Security or on a Redemption Date shall be paid to the Person
to whom principal is paid. The initial payment of interest on any Security that
is issued between a Regular Record Date and the related Interest Payment Date
shall be payable as provided in such Security.

      (c) Any interest on any Security that is due and payable, but is not
timely paid or duly provided for, on any Interest Payment Date for Securities
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date

                                       25
<PAGE>
by virtue of having been such Holder, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in paragraph (i) or (ii)
below:

            (i) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities (or their respective
      Predecessor Securities) are registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest (a "Special
      Record Date"), which shall be fixed in the following manner. At least
      thirty (30) days prior to the date of the proposed payment, the Company
      shall notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on each Security and the date of the proposed payment,
      and at the same time the Company shall deposit with the Trustee an amount
      of money equal to the aggregate amount proposed to be paid in respect of
      such Defaulted Interest or shall make arrangements satisfactory to the
      Trustee for such deposit prior to the date of the proposed payment, such
      money when deposited to be held in trust for the benefit of the Persons
      entitled to such Defaulted Interest. Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be not more than fifteen (15) days and not less than ten (10) days
      prior to the date of the proposed payment and not less than ten (10) days
      after the receipt by the Trustee of the notice of the proposed payment.
      The Trustee shall promptly notify the Company of such Special Record Date
      and, in the name and at the expense of the Company, shall cause notice of
      the proposed payment of such Defaulted Interest and the Special Record
      Date therefor to be mailed, first class, postage prepaid, to each Holder
      of a Security at the address of such Holder as it appears in the
      Securities Register not less than ten (10) days prior to such Special
      Record Date. Notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor having been so mailed, such Defaulted
      Interest shall be paid to the Persons in whose names the Securities (or
      their respective Predecessor Securities) are registered on such Special
      Record Date; or

            (ii) The Company may make payment of any Defaulted Interest 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 (or by the Trustee if the
      Securities are not listed), if, after notice given by the Company to the
      Trustee of the proposed payment pursuant to this clause, such payment
      shall be deemed practicable by the Trustee.

      (d) Payments of interest on the Securities shall include interest accrued
to but excluding the respective Interest Payment Dates. Interest payments for
the Securities shall be computed and paid (i) during the Fixed Rate Period on
the basis of a 360-day year of twelve 30-day months and (ii) thereafter on the
basis of a 360-day year and the actual number of days elapsed in the relevant
interest period.

      (e) Payment of principal of, premium, if any, and interest on the
Securities shall be made 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. Payments of principal, premium, if any, and interest due at the
Maturity of such Securities shall be made at the Place of Payment upon surrender
of such Securities to the Paying Agent and payments of interest shall be made
subject to such surrender where applicable, by wire transfer at such place and
to such account at a banking institution in the United States as may be
designated in writing to the Paying Agent at

                                       26
<PAGE>
least ten (10) Business Days prior to the date for payment by the Person
entitled thereto unless proper written transfer instructions have not been
received by the relevant record date, in which case such payments shall be made
by check mailed to the address of such Person as such address shall appear in
the Security Register.

      (f) Subject to the foregoing provisions of this Section 3.1, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, that were carried by such other Security.

      SECTION 3.2. Denominations.

      The Securities shall be in registered form without coupons and shall be
issuable in minimum denominations of $100,000 and any integral multiple of
$1,000 in excess thereof.

      SECTION 3.3. Execution, Authentication, Delivery and Dating.

      (a) At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities in an aggregate principal
amount (including all then Outstanding Securities) not in excess of Two Hundred
Million Dollars ($200,000,000) executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon:

            (i) a copy of any Board Resolution relating thereto; and

            (ii) an Opinion of Counsel substantially to the effect that: (1)
      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, and the Indenture
      constitutes, valid and legally binding obligations of the Company, each
      enforceable in accordance with its terms, subject to bankruptcy,
      insolvency, fraudulent transfer, reorganization, moratorium and similar
      laws of general applicability relating to or affecting creditors' rights
      and to general equity principles; (2) the Securities have been duly
      authorized and executed by the Company and have been delivered to the
      Trustee for authentication in accordance with this Indenture; (3) the
      Securities are not required to be registered under the Securities Act; and
      (4) the Indenture is not required to be qualified under the Trust
      Indenture Act.

      (b) The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, its Chief Financial Officer, its President or one of its Vice
Presidents. The signature of any of these officers on the Securities may be
manual or facsimile. Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

                                       27
<PAGE>
      (c) 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
executed by the Trustee by the manual signature of one of its authorized
signatories, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.8, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

      (d) Each Security shall be dated the date of its authentication.

      SECTION 3.4. Global Securities.

      (a) Upon the election of the Holder after the Original Issue Date, which
election need not be in writing, the Securities owned by such Holder shall be
issued in the form of one or more Global Securities registered in the name of
the Depositary or its nominee. Each Global Security issued under this Indenture
shall be registered in the name of the Depositary designated by the Company for
such Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture. In connection
with any such election, if requested by a Holder in writing, the Company will
act reasonably (including, without limitation, in light of Section 2.6 of this
Indenture) in designating and entering into any necessary arrangements, at the
cost of such Holder, with a Depositary reasonably acceptable to it and such
Holder.

      (b) Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for registered Securities, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (i) such Depositary advises the Trustee and the Company in
writing that such Depositary is no longer willing or able to properly discharge
its responsibilities as Depositary with respect to such Global Security, and no
qualified successor is appointed by the Company within ninety (90) days of
receipt by the Company of such notice, (ii) such Depositary ceases to be a
clearing agency registered under the Exchange Act and no successor is appointed
by the Company within ninety (90) days after obtaining knowledge of such event,
(iii) the Company executes and delivers to the Trustee a Company Order stating
that the Company elects to terminate the book-entry system through the
Depositary or (iv) an Event of Default shall have occurred and be continuing.
Upon the occurrence of any event specified in clause (i), (ii), (iii) or (iv)
above, the Trustee shall notify the Depositary and instruct the Depositary to
notify all owners of beneficial interests in such Global Security of the
occurrence of such event and of the availability of Securities to such owners of
beneficial interests requesting the same. The Trustee may conclusively rely, and
be protected in relying, upon the written identification of the owners of
beneficial interests furnished by the Depositary, and shall not be liable for
any delay resulting from a delay by the Depositary. Upon the issuance of such
Securities and the registration in the Securities Register of such Securities in
the names of the Holders of the beneficial interests therein, the Trustees shall
recognize such holders of beneficial interests as Holders.

                                       28
<PAGE>

      (c) If any Global Security is to be exchanged for other Securities or
canceled in part, or if another Security is to be exchanged in whole or in part
for a beneficial interest in any Global Security, then either (i) such Global
Security shall be so surrendered for exchange or cancellation as provided in
this Article III or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to (x) the portion thereof to be so exchanged or
canceled, or (y) the principal amount of such other Security to be so exchanged
for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Securities Registrar,
whereupon the Trustee, in accordance with the Applicable Depositary Procedures,
shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Security by the Depositary, accompanied by registration
instructions, the Company shall execute and the Trustee shall authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) in accordance with the instructions of the Depositary. The
Trustee shall not be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be fully protected in relying on, such
instructions.

      (d) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof shall be authenticated and delivered in the form of, and shall be, a
Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof.

      (e) [Reserved].

      (f) The Depositary or its nominee, as the registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under
this Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Depositary
Procedures. Accordingly, any such owner's beneficial interest in a Global
Security shall be shown only on, and the transfer of such interest shall be
effected only through, records maintained by the Depositary or its nominee or
its Depositary Participants. The Securities Registrar and the Trustee shall be
entitled to deal with the Depositary for all purposes of this Indenture relating
to a Global Security (including the payment of principal and interest thereon
and the giving of instructions or directions by owners of beneficial interests
therein and the giving of notices) as the sole Holder of the Security and shall
have no obligations to the owners of beneficial interests therein. Neither the
Trustee nor the Securities Registrar shall have any liability in respect of any
transfers effected by the Depositary.

      (g) The rights of owners of beneficial interests in a Global Security
shall be exercised only through the Depositary and shall be limited to those
established by law and agreements between such owners and the Depositary and/or
its Depositary Participants.

      (h) No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the owner of
such Global Security for all purposes whatsoever. None of the Company, the
Trustee nor any agent of the Company or the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests. Notwithstanding the foregoing, nothing herein

                                       29
<PAGE>
shall 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 a Depositary or impair, as between a Depositary and
such holders of beneficial interests, the operation of customary practices
governing the exercise of the rights of the Depositary (or its nominee) as
Holder of any Security.

      SECTION 3.5.  Registration, Transfer and Exchange Generally.

      (a) The Trustee shall cause to be kept at the Corporate Trust Office a
register (the "Securities Register") in which the registrar and transfer agent
with respect to the Securities (the "Securities Registrar"), subject to such
reasonable regulations as it may prescribe, shall provide for the registration
of Securities and of transfers and exchanges of Securities. The Trustee shall at
all times also be the Securities Registrar. The provisions of Article VI shall
apply to the Trustee in its role as Securities Registrar.

      (b) Subject to compliance with Section 2.2(b), upon surrender for
registration of transfer of any Security at the offices or agencies of the
Company designated for that purpose the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations of like
tenor and aggregate principal amount.

      (c) At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations, of like tenor and aggregate
principal amount, upon surrender of the Securities to be exchanged at such
office or agency. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities that the Holder making the exchange is entitled to receive.

      (d) All Securities issued upon any transfer or exchange of Securities
shall be the 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.

      (e) Every Security presented or surrendered for transfer or exchange shall
(if so required by the Company or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or
such Holder's attorney duly authorized in writing.

      (f) No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

      (g) Neither the Company nor the Trustee shall be required pursuant to the
provisions of this Section 3.5 (g): (i) to issue, register the transfer of or
exchange any Security during a period beginning at the opening of business
fifteen (15) days before the day of selection for redemption of Securities
pursuant to Article XI and ending at the close of business on the day of mailing
of the notice of redemption or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except, in the case of
any such Security to be redeemed in part, any portion thereof not to be
redeemed.

                                       30
<PAGE>
      (h) The Company shall designate an office or offices or agency or agencies
where Securities may be surrendered for registration or transfer or exchange.
The Company initially designates the Corporate Trust Office as its office and
agency for such purposes. The Company shall give prompt written notice to the
Trustee and to the Holders of any change in the location of any such office or
agency.

      SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

      (a) If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Trustee to save the Company
and the Trustee harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of like tenor and
aggregate principal amount and bearing a number not contemporaneously
outstanding.

      (b) If there shall be delivered to the Trustee (i) evidence to its
satisfaction of the destruction, loss or theft of any Security and (ii) such
security or indemnity as may be required by it to save each of the Company and
the Trustee harmless, then, in the absence of notice to the Company 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 lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and aggregate principal amount as such
destroyed, lost or stolen Security, and bearing a number not contemporaneously
outstanding.

      (c) If any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

      (d) Upon the issuance of any new Security under this Section 3.6, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

      (e) Every new Security issued pursuant to this Section 3.6 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

      (f) The provisions of this Section 3.6 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 3.7. Persons Deemed Owners.

      The Company, the Trustee and any agent of the Company or the Trustee shall
treat the Person in whose name any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any interest
on such Security and for all other purposes whatsoever, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

                                       31
<PAGE>
      SECTION 3.8. Cancellation.

      All Securities surrendered for payment, redemption, transfer or exchange
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee, and any such Securities and Securities surrendered directly to the
Trustee for any such purpose shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder that the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 3.8, except as expressly
permitted by this Indenture. All canceled Securities shall be retained or
disposed of by the Trustee in accordance with its customary practices and the
Trustee shall deliver to the Company a certificate of such disposition.

      SECTION 3.9. Deferrals of Interest Payment Dates.

      (a) So long as no Event of Default has occurred and is continuing, the
Company shall have the right, at any time and from time to time during the term
of the Security, to defer the payment of interest on the Securities for a period
of up to twenty (20) consecutive quarterly interest payment periods (each such
period, an "Extension Period"), during which Extension Period(s), the Company
shall have the right to make no payments or partial payments of interest on any
Interest Payment Date (except any Additional Amounts that otherwise may be due
and payable). No Extension Period shall end on a date other than an Interest
Payment Date and no Extension Period shall extend beyond the Stated Maturity of
the principal of the Securities. No interest shall be due and payable during an
Extension Period, except at the end thereof, but each installment of interest
that would otherwise have been due and payable during such Extension Period
shall bear Additional Interest (to the extent payment of such interest would be
legally enforceable) at the rate equal to a fixed rate equal to 8.48% per annum
through but excluding June 15, 2012 and thereafter at a variable rate equal to
LIBOR plus 2.95% per annum, compounded quarterly, from the dates on which
amounts would have otherwise been due and payable until paid or until funds for
the payment thereof have been made available for payment. At the end of any such

exercised by such Holder or any collateral manager thereof.

      SECTION 5.9. Restoration of Rights and Remedies.

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

      SECTION 5.10. Rights and Remedies Cumulative.

      Except as otherwise provided in Section 3.6(f), no right or remedy herein
conferred upon or reserved to the Trustee or the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

      SECTION 5.11. Delay or Omission Not Waiver.

      No delay or omission of the Trustee or any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article V or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or the Holders, as the case may
be.

      SECTION 5.12. Control by Holders.

      The Holders of not less than a majority in aggregate principal amount of
the Outstanding Securities shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee; provided, that:

      (a) such direction shall not be in conflict with any rule of law or with
this Indenture,

      (b) the Trustee may take any other action deemed proper by the Trustee
that is not inconsistent with such direction, and

      (c) subject to the provisions of Section 6.2, the Trustee shall have the
right to decline to follow such direction if a Responsible Officer or Officers
of the Trustee shall, in good faith, reasonably determine that the proceeding so
directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability.

      SECTION 5.13. Waiver of Past Defaults.

      (a) The Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities may waive any past Event of Default hereunder and
its consequences except an Event of Default:

            (i) in the payment of the principal of or any premium or interest
      (including any Additional Interest) on any Security (unless such Event of
      Default has been cured and the Company has paid to or deposited with the
      Trustee a sum sufficient to pay all installments of interest (including
      any Additional Interest) due and past due and all principal of and any
      premium on all Securities due otherwise than by acceleration), or

            (ii) in respect of a covenant or provision hereof that under Article
      IX cannot be modified or amended without the consent of each Holder of any
      Outstanding Security.

      (b) Any such waiver shall be deemed to be on behalf of the Holders of all
the Securities.

      (c) Upon any such waiver, such Event of Default shall cease to exist and
any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Event of Default or impair any right consequent thereon.

      SECTION 5.14. Undertaking for Costs.

      All parties to this Indenture agree, and each Holder of any Security by
his or her acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.14 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Holder, or group of Holders, holding
in the aggregate more than ten percent (10%) in aggregate principal amount of
the Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of or any premium on the Security
after the Stated Maturity or any interest (including any Additional Interest) on
any Security after it is due and payable.

      SECTION 5.15. Waiver of Usury, Stay or Extension 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 usury, stay or extension law wherever
enacted, now or at any time hereafter in force, 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.

                                   ARTICLE VI

                                   THE TRUSTEE

      SECTION 6.1. Corporate Trustee Required.

      There shall at all times be a Trustee hereunder with respect to the
Securities. The Trustee shall be a corporation organized and doing business
under the laws of the United States or of any state thereof, authorized to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000, subject to supervision or examination by Federal or state
authority and having an office within the United States. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of such supervising or examining authority, then, for the purposes
of this Section 6.1, the combined capital and surplus of such corporation shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.1, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article VI.

      SECTION 6.2. Certain Duties and Responsibilities.

      Except during the continuance of an Event of Default:

            (i) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture, and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; 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;
      provided, that in the case of any such certificates or opinions that by
      any provision hereof are specifically required to be furnished to the
      Trustee, the Trustee shall be under a duty to examine the same to
      determine whether or not they substantially conform on their face to the
      requirements of this Indenture.

      (b) If an Event of Default known to the Trustee has occurred and is
continuing, the Trustee shall, prior to the receipt of directions, if any, from
the Holders of at least a majority in aggregate principal amount of the
Outstanding Securities, exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

      (c) Notwithstanding the foregoing, no provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 6.2. To the extent that, at law or in
equity, the Trustee has duties and liabilities relating to the Holders, the

                                       44
<PAGE>

Trustee shall not be liable to any Holder for the Trustee's good faith reliance
on the provisions of this Indenture. The provisions of this Indenture, to the
extent that they restrict the duties and liabilities of the Trustee otherwise
existing at law or in equity, are agreed by the Company and the Holders to
replace such other duties and liabilities of the Trustee.

      (d) No provisions of this Indenture shall be construed to relieve the
Trustee from liability with respect to matters that are within the authority of
the Trustee under this Indenture for its own negligent action, negligent failure
to act or willful misconduct, except that:

            (i) the Trustee shall not be liable for any error or judgment made
      in good faith by an authorized officer of the Trustee, unless it shall be
      proved that the Trustee was negligent in ascertaining the pertinent facts;

            (ii) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the Holders of at least a majority in aggregate principal
      amount of the Outstanding Securities relating to the time, method and
      place of conducting any proceeding for any remedy available to the Trustee
      under this Indenture; and

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

      SECTION 6.3. Notice of Defaults.

      Within ninety (90) days after the occurrence of any default actually known
to the Trustee, the Trustee shall give the Holders notice of such default unless
such default shall have been cured or waived; provided, that except in the case
of a default in the payment of the principal of or any premium or interest on
any Securities, the Trustee shall be fully protected in withholding the notice
if and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determines that withholding the notice is in the interest of holders of
Securities; and provided, further, that in the case of any default of the
character specified in Section 5.1(c), no such notice to Holders shall be given
until at least thirty (30) days after the occurrence thereof. For the purpose of
this Section 6.3, the term "default" means any event which is, or after notice
or lapse of time or both would become, an Event of Default.

      SECTION 6.4. Certain Rights of Trustee.

      Subject to the provisions of Section 6.2:

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

                                       45
<PAGE>

      (b) if (i) in performing its duties under this Indenture the Trustee is
required to decide between alternative courses of action, (ii) in construing any
of the provisions of this Indenture the Trustee finds ambiguous or inconsistent
with any other provisions contained herein or (iii) the Trustee is unsure of the
application of any provision of this Indenture, then, except as to any matter as
to which the Holders are entitled to decide under the terms of this Indenture,
the Trustee shall deliver a notice to the Company requesting the Company's
written instruction as to the course of action to be taken and the Trustee shall
take such action, or refrain from taking such action, as the Trustee shall be
instructed in writing to take, or to refrain from taking, by the Company;
provided, that if the Trustee does not receive such instructions from the
Company within ten Business Days after it has delivered such notice or such
reasonably shorter period of time set forth in such notice the Trustee may, but
shall be under no duty to, take such action, or refrain from taking such action,
as the Trustee shall deem advisable and in the best interests of the Holders, in
which event the Trustee shall have no liability except for its own negligence,
bad faith or willful misconduct;

      (c) any request or direction of the Company 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;

      (d) the Trustee may consult with counsel (which counsel may be counsel to
the Trustee, the Company or any of its Affiliates, and may include any of its
employees) and the advice of such counsel or any Opinion of Counsel shall be
full and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon;

      (e) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee security or indemnity reasonably satisfactory to it against the
costs, expenses (including reasonable attorneys' fees and expenses) and
liabilities that might be incurred by it in compliance with such request or
direction, including reasonable advances as may be requested by the Trustee;

      (f) 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, indenture,
note or other paper or document, but the Trustee in its discretion may make such
inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company, personally
or by agent or attorney;

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

      (h) whenever in the administration of this Indenture the Trustee shall
deem it desirable to receive instructions with respect to enforcing any remedy
or right or taking any other action with respect to enforcing any remedy or
right hereunder, the Trustees (i) may request instructions from the Holders
(which instructions may only be given by the Holders of the same

                                       46
<PAGE>

aggregate principal amount of Outstanding Securities as would be entitled to
direct the Trustee under this Indenture in respect of such remedy, right or
action), (ii) may refrain from enforcing such remedy or right or taking such
action until such instructions are received and (iii) shall be protected in
acting in accordance with such instructions;

      (i) except as otherwise expressly provided by this Indenture, the Trustee
shall not be under any obligation to take any action that is discretionary under
the provisions of this Indenture;

      (j) without prejudice to any other rights available to the Trustee under
applicable law, when the Trustee incurs expenses or renders services in
connection with any bankruptcy, insolvency or other proceeding referred to in
clauses (d) or (e) of the definition of Event of Default, such expenses
(including legal fees and expenses of its agents and counsel) and the
compensation for such services are intended to constitute expenses of
administration under any bankruptcy laws or law relating to creditors rights
generally;

      (k) 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 addressing such matter, which,
upon receipt of such request, shall be promptly delivered by the Company;

      (l) the Trustee shall not be charged with knowledge of any Event of
Default unless either (i) a Responsible Officer of the Trustee shall have actual
knowledge or (ii) the Trustee shall have received written notice thereof from
the Company or a Holder; and

      (m) in the event that the Trustee is also acting as Paying Agent,
Authenticating Agent or Securities Registrar hereunder, the rights and
protections afforded to the Trustee pursuant to this Article VI shall also be
afforded such Paying Agent, Authenticating Agent, or Securities Registrar.

      SECTION 6.5. May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Securities
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Securities Registrar or such other agent.

      SECTION 6.6. Compensation; Reimbursement; Indemnity.

      (a) The Company agrees:

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

                                       47
<PAGE>

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

            (iii) to the fullest extent permitted by applicable law, to
      indemnify the Trustee and its Affiliates, and their officers, directors,
      shareholders, agents, representatives and employees for, and to hold them
      harmless against, any loss, damage, liability, tax (other than income,
      franchise or other taxes imposed on amounts paid pursuant to (i) or (ii)
      hereof), penalty, expense or claim of any kind or nature whatsoever
      incurred without negligence, bad faith or willful misconduct on its part
      arising out of or in connection with the acceptance or administration of
      this trust or the performance of the Trustee's duties hereunder, including
      the costs and expenses of defending itself against any claim or liability
      in connection with the exercise or performance of any of its powers or
      duties hereunder.

      (b) To secure the Company's payment obligations in this Section 6.6, the
Company hereby grants and pledges to the Trustee and the Trustee shall have a
lien prior to the Securities on all money or property held or collected by the
Trustee, other than money or property held in trust to pay principal and
interest on particular Securities. Such lien shall survive the satisfaction and
discharge of this Indenture or the resignation or removal of the Trustee.

      (c) The obligations of the Company under this Section 6.6 shall survive
the satisfaction and discharge of this Indenture and the earlier resignation or
removal of the Trustee.

      (d) In no event shall the Trustee be liable for any indirect, special,
punitive or consequential loss or damage of any kind whatsoever, including, but
not limited to, lost profits, even if the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action.

      (e) In no event shall the Trustee be liable for any failure or delay in
the performance of its obligations hereunder because of circumstances beyond its
control, including, but not limited to, acts of God, flood, war (whether
declared or undeclared), terrorism, fire, riot, embargo, government action,
including any laws, ordinances, regulations, governmental action or the like
which delay, restrict or prohibit the providing of the services contemplated by
this Indenture.

      SECTION 6.7. Resignation and Removal; Appointment of Successor.

      (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article VI shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.8.

      (b) The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 6.8 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series. If the

                                       48
<PAGE>

acceptance of appointment is substantially contemporaneous with the resignation,
then the notice called for by the first sentence of this subsection may be
combined with the instrument called for by Section 6.8.

      (c) Unless an Event of Default shall have occurred and be continuing, the
Trustee may be removed at any time by the Company by a Board Resolution. If an
Event of Default shall have occurred and be continuing, the Trustee may be
removed by Act of the Holders of a majority in aggregate principal amount of the
Outstanding Securities, delivered to the Trustee and to the Company.

      (d) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any reason, at a time
when no Event of Default shall have occurred and be continuing, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee, and such
successor Trustee and the retiring Trustee shall comply with the applicable
requirements of Section 6.8. If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any reason, at a time when an Event of Default shall have occurred and be
continuing, the Holders, by Act of the Holders of a majority in aggregate
principal amount of the Outstanding Securities, shall promptly appoint a
successor Trustee, and such successor Trustee and the retiring Trustee shall
comply with the applicable requirements of Section 6.8. If no successor Trustee
shall have been so appointed by the Company or the Holders and accepted
appointment within sixty (60) days after the giving of a notice of resignation
by the Trustee or the removal of the Trustee in the manner required by Section
6.8, any Holder who has been a bona fide Holder of a Security for at least six
months may, on behalf of such Holder and all others similarly situated, and any
resigning Trustee may, at the expense of the Company, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

      (e) The Company shall give notice to all Holders in the manner provided in
Section 1.6 of each resignation and each removal of the Trustee and each
appointment of a successor Trustee. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

      SECTION 6.8. Acceptance of Appointment by Successor.

      (a) In case of the appointment hereunder of a successor Trustee, each
successor Trustee so appointed shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.

      (b) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all rights, powers and trusts referred to in paragraph
(a) of this Section 6.8.

                                       49
<PAGE>

      (c) No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article VI.

      SECTION 6.9. Merger, Conversion, Consolidation or Succession to Business.

      Any Person into which the Trustee may be merged or converted or with which
it may be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any Person succeeding to
all or substantially all of the corporate trust business of the Trustee, shall
be the successor of the Trustee hereunder, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, provided,
that such Person shall be otherwise qualified and eligible under this Article
VI. In case any Securities shall have been authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or consolidation
or as otherwise provided above in this Section 6.9 to such authenticating
Trustee may adopt such authentication and deliver the Securities so
authenticated, and in case any Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor Trustee or in the name of such successor Trustee, and in all
cases the certificate of authentication shall have the full force which it is
provided anywhere in the Securities or in this Indenture that the certificate of
the Trustee shall have.

      SECTION 6.10. Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of the Securities or the proceeds thereof.

      SECTION 6.11. Appointment of Authenticating Agent.

      (a) The Trustee may appoint an Authenticating Agent or Agents with respect
to the Securities, which shall be authorized to act on behalf of the Trustee to
authenticate Securities issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
3.6, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, or of any State or Territory thereof or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or state authority. If such Authenticating
Agent publishes reports of condition at least annually pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section 6.11 the combined capital and surplus of such Authenticating
Agent shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published. If at

                                       50
<PAGE>

any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section 6.11, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 6.11.

      (b) Any Person into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion or consolidation to which such Authenticating Agent shall be
a party, or any Person succeeding to all or substantially all of the corporate
trust business of an Authenticating Agent shall be the successor Authenticating
Agent hereunder, provided such Person shall be otherwise eligible under this
Section 6.11, without the execution or filing of any paper or any further act on
the part of the Trustee or the Authenticating Agent.

      (c) An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.11, the Trustee may appoint a successor
Authenticating Agent eligible under the provisions of this Section 6.11, which
shall be acceptable to the Company, and shall give notice of such appointment to

      SECTION 10.1. Payment of Principal, Premium, if any, and Interest.

      The Company covenants and agrees for the benefit of the Holders of the
Securities that it will duly and punctually pay the principal of and any premium

with the terms of the Securities and this Indenture. As of the date of this
Indenture, the Company represents that it has no present intention to exercise
its right under Section 2.11 to defer payments of interest on the Securities.

      SECTION 10.2. Money for Security Payments to be Held in Trust.

      (a) If the Company shall at any time act as its own Paying Agent with
respect to the Securities, it will, on or before each due date of the principal
of and any premium or interest (including any Additional Interest) on the
Securities, segregate and hold in trust for the benefit of the Persons entitled

prior to 10:00 a.m., New York City time, on each due date of the principal of or
any premium or interest (including any Additional Interest) on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided in the Trust Indenture Act and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its failure so to act.

      (c) The Company will cause each Paying Agent for the Securities other than
the Trustee to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee, subject to the provisions of this
Section 10.2, that such Paying Agent will (i) comply with the provisions of this
Indenture and the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor

      (d) The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

      (e) Any money deposited with the Trustee or any Paying Agent, or then held
by the Company in trust for the payment of the principal of and any premium or
interest (including any Additional Interest) on any Security and remaining
unclaimed for two years after such principal

                                       57
<PAGE>

and any premium or interest has become due and payable shall (unless otherwise
required by mandatory provision of applicable escheat or abandoned or unclaimed
property law) be paid on Company Request to the Company, or (if then held by the
Company) shall (unless otherwise required by mandatory provision of applicable
escheat or abandoned or unclaimed property law) be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the Borough of Manhattan, The City of New York,
notice that such money remains unclaimed and that, after a date specified

      SECTION 10.3. Statement as to Compliance.

      The Company shall deliver to the Trustee, within ninety (90) days after
the end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate covering the preceding calendar year, stating whether or
not to the knowledge of the signers thereof the Company is in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture (without regard to any period of grace or requirement of notice
provided hereunder), 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 10.4. Calculation Agent.

      (a) The Company hereby agrees that for so long as any of the Securities
remain Outstanding, there will at all times be an agent appointed to calculate
LIBOR in respect of each Interest Payment Date in accordance with the terms of
Schedule A (the "Calculation Agent"). The Company has initially appointed the
Trustee as Calculation Agent for purposes of determining LIBOR for each Interest
Payment Date. The Calculation Agent may be removed by the Company at any time.
If the Calculation Agent is unable or unwilling to act as such or is removed by
the Company, the Company will promptly appoint as a replacement Calculation
Agent the London office of a leading bank which is engaged in transactions in
Eurodollar deposits in the international Eurodollar market and which does not
control or is not controlled by or under common control with the Company or its
Affiliates. The Calculation Agent may not resign its duties without a successor
having been duly appointed.

      (b) The Calculation Agent shall be required to agree that, as soon as
possible after 11:00 a.m. (London time) on each LIBOR Determination Date (as
defined in Schedule A), but in no event later than 11:00 a.m. (London time) on
the Business Day immediately following each LIBOR Determination Date, the
Calculation Agent will calculate the interest rate (the Interest Payment shall
be rounded to the nearest cent, with half a cent being rounded upwards) for the
related Interest Payment Date, and will communicate such rate and amount to the
Company, the Trustee, each Paying Agent and the Depositary. The Calculation
Agent will also specify to the Company the quotations upon which the foregoing
rates and amounts are based and, in any event, the Calculation Agent shall
notify the Company before 5:00 p.m. (London time) on each

                                       58
<PAGE>

LIBOR Determination Date that either: (i) it has determined or is in the process
of determining the foregoing rates and amounts or (ii) it has not determined and
is not in the process of determining the foregoing rates and amounts, together
with its reasons therefor. The Calculation Agent's determination of the
foregoing rates and amounts for any Interest Payment Date will (in the absence
of manifest error) be final and binding upon all parties. For the sole purpose
of calculating the interest rate for the Securities, "Business Day" shall be
defined as any day on which dealings in deposits in Dollars are transacted in
the placeCityLondon interbank market.

      SECTION 10.5. Additional Amounts.

      All payments of principal of and premium, if any, interest (including any
Additional Interest) and any other amounts on, or in respect of, the Securities
of any series shall be made without withholding or deduction at source for, or
on account of, any present or future taxes, fees, duties, assessments or
governmental charges of whatever nature imposed or levied by or on behalf of
Bermuda or any other jurisdiction in which the Company is organized (each, a
"taxing jurisdiction") or any political subdivision or taxing authority thereof
or therein, unless such taxes, fees, duties, assessments or governmental charges
are required to be withheld or deducted by (i) the laws (or any regulations or
ruling promulgated thereunder) of a taxing jurisdiction or any political
subdivision or taxing authority thereof or therein or (ii) an official position
regarding the application, administration, interpretation or enforcement of any
such laws, regulations or rulings (including, without limitation, a holding by a
court of competent jurisdiction or by a taxing authority in a taxing
jurisdiction or any political subdivision thereof).

      If a withholding or deduction at source is required, the Company shall,
subject to certain limitations and exceptions set forth below, pay to the Holder
of any such Security such additional amounts ("Additional Amounts") as may be
necessary so that every net payment of principal, premium, if any, interest
(including any Additional Interest) or any other amount made to such Holder,
after such withholding or deduction, shall not be less than the amount provided
for in such Security and this Indenture to be then due and payable; provided,
however, that the Company shall not be required to make payment of such
Additional Amounts for or on account of:

      (a) any tax, fee, duty, assessment or governmental charge of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of, or receipt of payment under, such Security; (B) presented
such Security, where presentation is required, for payment in the relevant
taxing jurisdiction or any political subdivision thereof, unless such Security
could not have been presented for payment elsewhere; or (C) presented such
Security, where presentation is required, more than thirty (30) days after the
date on which the payment in respect of such Security first became due and
payable or provided for, whichever is later, except to the extent that the
Holder would have been entitled to such Additional Amounts if it had presented
such Security for payment on any day within such period of thirty (30) days;

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

                                       59
<PAGE>

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

      (d) any withholding or deduction required to be made pursuant to any EU
Directive on the taxation of savings implementing the conclusions of the ECOFIN
Council meetings of 26-27 November 2000, 3 June 2003 or any law implementing or
complying with, or introduced in order to confirm to, such EU Directive; or

      (e) any combination of items (a), (b), (c) and (d);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required

tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

of the principal of or any premium, interest (including Additional Interest) or
any other amounts on, or in respect of, any Security of any series or the net
proceeds received on the sale or exchange of any Security of any series, such

the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms, and express mention of the
payment of Additional Amounts (if applicable) in any provision hereof shall not
be construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.

      the actual Redemption Price on the date that such Redemption Price is
      calculated);

            (iii) if less than all Outstanding Securities are to be redeemed,

      due and payable upon each such Security or portion thereof, and that any

redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security.

in the notice of redemption given as provided in Section 11.5, the Company will

provided in Section 10.2) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including any Additional Interest) on, all
the Securities (or portions thereof) that are to be redeemed on that date.

      SECTION 11.7. Payment of Securities Called for Redemption.

places stated in such notice at the applicable Redemption Price, together with

principal amount equal to the unredeemed portion of the Security so presented
and having the same Original Issue Date, Stated Maturity and terms.

      (c) If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and any premium on such

                           SUBORDINATION OF SECURITIES

      SECTION 12.1. Securities Subordinate to Senior Debt.

      The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article XII, the payment of the
principal of and any premium and interest (including any Additional Interest) on
each and all of the Securities are hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all Senior Debt (whether
outstanding on the date hereof or hereafter created, incurred, assumed or
guaranteed).

      SECTION 12.2. No Payment When Senior Debt in Default; Payment Over of
Proceeds Upon Dissolution, Etc.

      (a) In the event and during the continuation of any default by the Company
in the payment of any principal of or any premium or interest on any Senior Debt
(following any grace period, if applicable) when the same becomes due and
payable, whether at maturity or at a date fixed for prepayment or by declaration
of acceleration or otherwise, then, upon written notice of such default to the
Company by the holders of such Senior Debt or any trustee therefor, unless and
until such default shall have been cured or waived or shall have ceased to
exist, no direct or indirect payment (in cash, property, securities, by set-off
or otherwise) shall be made or agreed to be made on account of the principal of
or any premium or interest (including any Additional Interest) on any of the
Securities, or in respect of any redemption, repayment, retirement, purchase or
other acquisition of any of the Securities.

      (b) In the event of a bankruptcy, insolvency or other proceeding described
in clause (d) or (e) of the definition of Event of Default (each such event, if
any, herein sometimes referred to as a "Proceeding"), all Senior Debt (including
any interest thereon accruing after the commencement of any such proceedings)
shall first be paid in full before any payment or distribution, whether in cash,
securities or other property, shall be made to any Holder of any of the
Securities on account thereof. Any payment or distribution, whether in cash,
securities or other property (other than securities of the Company or any other
entity provided for by a plan of reorganization or readjustment the payment of
which is subordinate, at least to the extent provided in these subordination
provisions with respect to the indebtedness evidenced by the Securities, to the
payment of all Senior Debt at the time outstanding and to any securities issued
in respect thereof under any such plan of reorganization or readjustment), which
would otherwise (but for these subordination provisions) be payable or
deliverable in respect of the Securities shall be paid or delivered directly to
the holders of Senior Debt in accordance with the priorities

                                       65
<PAGE>

then existing among such holders until all Senior Debt (including any interest
thereon accruing after the commencement of any Proceeding) shall have been paid
in full.

      (c) In the event of any Proceeding, after payment in full of all sums
owing with respect to Senior Debt, the Holders of the Securities, together with
the holders of any obligations of the Company ranking on a parity with the
Securities, shall be entitled to be paid from the remaining assets of the
Company the amounts at the time due and owing on account of unpaid principal of
and any premium and interest (including any Additional Interest) on the
Securities and such other obligations before any payment or other distribution,
whether in cash, property or otherwise, shall be made on account of any capital
stock or any obligations of the Company ranking junior to the Securities and
such other obligations. If, notwithstanding the foregoing, any payment or
distribution of any character or any security, whether in cash, securities or
other property (other than securities of the Company or any other entity
provided for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Securities, to the payment of
all Senior Debt at the time outstanding and to any securities issued in respect
thereof under any such plan of reorganization or readjustment) shall be received
by the Trustee or any Holder in contravention of any of the terms hereof and
before all Senior Debt shall have been paid in full, such payment or
distribution or security shall be received in trust for the benefit of, and
shall be paid over or delivered and transferred to, the holders of the Senior
Debt at the time outstanding in accordance with the priorities then existing
among such holders as calculated and certified by the Company for application to
the payment of all Senior Debt remaining unpaid, to the extent necessary to pay
all such Senior Debt (including any interest thereon accruing after the
commencement of any Proceeding) in full. In the event of the failure of the
Trustee or any Holder to endorse or assign any such payment, distribution or
security, each holder of Senior Debt is hereby irrevocably authorized to endorse
or assign the same.

      (d) The Trustee and the Holders, at the expense of the Company, shall take
such reasonable action (including the delivery of this Indenture to an agent for
any holders of Senior Debt or consent to the filing of a financing statement
with respect hereto) as may, in the opinion of counsel designated by the holders
of a majority in principal amount of the Senior Debt at the time outstanding, be
necessary or appropriate to assure the effectiveness of the subordination
effected by these provisions.

      (e) The provisions of this Section 12.2 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

      (f) The securing of any obligations of the Company, otherwise ranking on a
parity with the Securities or ranking junior to the Securities, shall not be
deemed to prevent such obligations from constituting, respectively, obligations
ranking on a parity with the Securities or ranking junior to the Securities.

      SECTION 12.3. Payment Permitted If No Default.

      Nothing contained in this Article XII or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time, except during
the pendency of the conditions described in paragraph (a) of Section 12.2 or of
any Proceeding referred to in Section

                                       66
<PAGE>

12.2, from making payments at any time of principal of and any premium or
interest (including any Additional Interest) on the Securities or (b) the
application by the Trustee of any moneys deposited with it hereunder to the
payment of or on account of the principal of and any premium or interest
(including any Additional Interest) on the Securities or the retention of such
payment by the Holders, if, at the time of such application by the Trustee, it
did not have knowledge (in accordance with Section 12.8) that such payment would
have been prohibited by the provisions of this Article XII, except as provided
in Section 12.8.

      SECTION 12.4. Subrogation to Rights of Holders of Senior Debt.

      Subject to the payment in full of all amounts due or to become due on all
Senior Debt, or the provision for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, the Holders of
the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Debt pursuant to the provisions
of this Article XII (equally and ratably with the holders of all indebtedness of
the Company that by its express terms is subordinated to Senior Debt of the
Company to substantially the same extent as the Securities are subordinated to
the Senior Debt and is entitled to like rights of subrogation by reason of any
payments or distributions made to holders of such Senior Debt) to the rights of
the holders of such Senior Debt to receive payments and distributions of cash,
property and securities applicable to the Senior Debt until the principal of and
any premium and interest (including any Additional Interest) on the Securities
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article XII, and no payments made
pursuant to the provisions of this Article XII to the holders of Senior Debt by
Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Debt, and the Holders of the Securities,
be deemed to be a payment or distribution by the Company to or on account of the
Senior Debt.

      SECTION 12.5. Provisions Solely to Define Relative Rights.

      The provisions of this Article XII are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Debt on the other hand. Nothing contained in
this Article XII or elsewhere in this Indenture or in the Securities is intended
to or shall (a) impair, as between the Company and the Holders of the
Securities, the obligations of the Company, which are absolute and
unconditional, to pay to the Holders of the Securities the principal of and any
premium and interest (including any Additional Interest) on the Securities as
and when the same shall become due and payable in accordance with their terms,
(b) affect the relative rights against the Company of the Holders of the
Securities and creditors of the Company other than their rights in relation to
the holders of Senior Debt or (c) prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, including filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article XII of the holders
of Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

<PAGE>

      SECTION 12.6. Trustee to Effectuate Subordination.

      Each Holder of a Security by his or her acceptance thereof authorizes and
directs the Trustee on his or her behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination provided in this
Article XII and appoints the Trustee his or her attorney-in-fact for any and all
such purposes.

      SECTION 12.7. No Waiver of Subordination Provisions.

      (a) No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or be
otherwise charged with.

      (b) Without in any way limiting the generality of paragraph (a) of this
Section 12.7, the holders of Senior Debt may, at any time and from to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to such Holders of the Securities
and without impairing or releasing the subordination provided in this Article
XII or the obligations hereunder of such Holders of the Securities to the
holders of Senior Debt, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt
or any instrument evidencing the same or any agreement under which Senior Debt
is outstanding, (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Debt, (iii) release any Person
liable in any manner for the payment of Senior Debt and (iv) exercise or refrain
from exercising any rights against the Company and any other Person.

      SECTION 12.8. Notice to Trustee.

      (a) The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment to or by the Trustee in respect of the Securities.
Notwithstanding the provisions of this Article XII or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts that would prohibit the making of any payment to or by the Trustee
in respect of the Securities, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
of Senior Debt or from any trustee, agent or representative therefor; provided,
that if the Trustee shall not have received the notice provided for in this
Section 12.8 at least two Business Days prior to the date upon which by the
terms hereof any monies may become payable for any purpose (including, the
payment of the principal of and any premium on or interest (including any
Additional Interest) on any Security), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies and to apply the same to the purpose for which they were
received and shall not be affected by any notice to the contrary that may be
received by it within two Business Days prior to such date.

                                       68
<PAGE>

      (b) The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or herself to be a holder of
Senior Debt (or a trustee, agent, representative or attorney-in-fact therefor)
to establish that such notice has been given by a holder of Senior Debt (or a
trustee, agent, representative or attorney-in-fact therefor). In the event that
the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior Debt to participate in
any payment or distribution pursuant to this Article XII, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Debt held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article XII, and
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

      SECTION 12.9. Reliance on Judicial Order or Certificate of Liquidating
Agent.

      Upon any payment or distribution of assets of the Company referred to in
this Article XII, the Trustee and the Holders of the Securities shall be
entitled to conclusively rely upon any order or decree entered by any court of
competent jurisdiction in which such Proceeding is pending, or a certificate of
the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee
for the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of Securities, for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
XII.

      SECTION 12.10. Trustee Not Fiduciary for Holders of Senior Debt.

      The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be
liable to any such holders if it shall in good faith mistakenly pay over or
distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article XII or otherwise.

      SECTION 12.11. Rights of Trustee as Holder of Senior Debt; Preservation of
Trustee's Rights.

      The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article XII with respect to any Senior Debt that may at any
time be held by it, to the same extent as any other holder of Senior Debt, and
nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder.

      SECTION 12.12. Article Applicable to Paying Agents.

      If at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article XII shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article XII in addition to or in place of the Trustee; provided,
that Sections

12.8 and 12.11 shall not apply to the Company or any Affiliate of the Company if
the Company or such Affiliate acts as Paying Agent.

                             DETERMINATION OF LIBOR

      With respect to the Securities, the London interbank offered rate
("LIBOR") shall be determined by the Calculation Agent in accordance with the
following provisions (in each case rounded to the nearest .000001%):

(1) On the second LIBOR Business Day (as defined below) prior to an Interest
Payment Date (each such day, a "LIBOR Determination Date"), LIBOR for any given
security shall for the following interest payment period equal the rate, as
obtained by the Calculation Agent from Bloomberg Financial Markets Commodities
News, for three-month Eurodollar deposits that appears on Dow Jones Telerate
Page 3750 (as defined in the International Swaps and Derivatives Association,
Inc. 1991 Interest Rate and Currency Exchange Definitions), or such other page
as may replace such Page 3750, as of 11:00 a.m. (London time) on such LIBOR
Determination Date.

(2) If, on any LIBOR Determination Date, such rate does not appear on Dow Jones
Telerate Page 3750 or such other page as may replace such Page 3750, the
Calculation Agent shall determine the arithmetic mean of the offered quotations
of the Reference Banks (as defined below) to leading banks in the London
interbank market for three-month Eurodollar deposits in an amount determined by
the Calculation Agent by reference to requests for quotations as of
approximately 11:00 a.m. (London time) on the LIBOR Determination Date made by
the Calculation Agent to the Reference Banks. If, on any LIBOR Determination
Date, at least two of the Reference Banks provide such quotations, LIBOR shall
equal such arithmetic mean of such quotations. If, on any LIBOR Determination
Date, only one or none of the Reference Banks provide such quotations, LIBOR
shall be deemed to be the arithmetic mean of the offered quotations that leading
banks in the City of New York selected by the Calculation Agent are quoting on
the relevant LIBOR Determination Date for three-month Eurodollar deposits in an
amount determined by the Calculation Agent by reference to the principal London
offices of leading banks in the London interbank market; provided that, if the
Calculation Agent is required but is unable to determine a rate in accordance
with at least one of the procedures provided above, LIBOR shall be LIBOR as
determined on the previous LIBOR Determination Date.

(3) As used herein: "Reference Banks" means four major banks in the London
interbank market selected by the Calculation Agent; and "LIBOR Business Day"
means a day on which commercial banks are open for business (including dealings
in foreign exchange and foreign currency deposits) in London.

                         BACKSTOP SUBSCRIPTION AGREEMENT

            This BACKSTOP SUBSCRIPTION AGREEMENT, dated as of July 5, 2007 (this
"Agreement"), is made between VALIDUS HOLDINGS, LTD., a company with limited
liability organized under the laws of Bermuda (the "Company"), and each of the
undersigned (each, a "Major Investor" and collectively, the "Major Investors").

            WHEREAS, the Company has entered into a Share Sale Agreement dated
May 15, 2007 among the Company and the sellers identified therein relating to
the acquisition (the "Talbot Acquisition") by the Company of all of the issued
share capital of Talbot Holdings Ltd, a company organized under the laws of
Bermuda (together with its subsidiaries, "Talbot");

            WHEREAS the Company may make an offer to its members, in accordance
with the provisions of Section 4.1(e) of its Bye-Laws or otherwise, offering
(the "Offering") them the right to subscribe for Common Shares (as defined
below) of the Company; the purpose of the Offering being to provide additional
financial resources to the Company if the Talbot Acquisition is consummated
prior to the consummation of a public offering that provides net proceeds to the
Company of at least US$200,000,000; and

            WHEREAS, each of the Major Investors, subject to the terms and
conditions of this Agreement, has severally agreed (i) to purchase their Pro
Rata Portion (as defined in the Bye-Laws) of any Offering and (ii) to purchase
100% of their Percentage Commitment (as indicated on Schedule A hereto) of any
Common Shares not offered to (or if offered to, not for any reason subscribed
for by) members (other than Major Investors) in any such Offering, in each case
up to an aggregate several commitment for all Major Investors of US$200,000,000,
with each Major Investor agreeing to purchase its Percentage Commitment thereof.

            In consideration of the premises and mutual agreements herein
contained, the sufficiency of which is hereby acknowledged, the parties hereto
hereby agree as follows:

                                    ARTICLE I

                  AUTHORIZATION; SUBSCRIPTION FOR SECURITIES

            Section 1.1 The Securities. The Company has authorized the issuance
and sale of Voting Common Shares, par value US$0.175 per share (the "Voting
Common Shares"), and Non-Voting Common Shares, par value US$0.175 per share (the
"Non-Voting Common Shares" and, together with the Voting Common Shares, the
"Common Shares"), having a value (determined as set forth below) of
US$200,000,000, such shares each having such rights, restrictions and privileges
contained in the Memorandum of Association and Bye-Laws of the Company as in
effect from time to time (the "Memorandum of Association" and the "Bye-laws,"
respectively). Subject to the terms and conditions hereof, the purchase
severally by each of the Major Investors pursuant to this Agreement of the
Common Shares shall occur on one date (the "Closing Date") determined by the
Company and of which each of the Major Investors has been given at least ten
(10) business days' prior written notice (the "Closing Notice").

            The Company acknowledges that it will not deliver a Closing Notice
to a Major Investor unless a Closing Notice is delivered to each Major Investor
requiring each Major Investor to purchase its full Percentage Commitment of any
such Offering.

            Section 1.2 Subscription for Securities Pursuant to This Agreement.
Subject to the terms and conditions of this Agreement, each Major Investor,
acting severally and not jointly, hereby ir-

<PAGE>

revocably subscribes for and agrees to purchase on the Closing Date up to the
number of Common Shares of the applicable series set forth opposite its name on
Schedule A attached hereto (the "Securities"), for a purchase price per Security
as determined by the Board of Directors (based on the recommendation by the
Finance Committee) and acceptable to the Qualified Sponsors (as defined in the
Bye-Laws) in their sole discretion (the "Purchase Price"). Notwithstanding any
other provision of this Agreement, any Major Investor shall be entitled at any
time prior to the Closing Date to designate in writing one or more entities
affiliated with such Major Investor to purchase the Securities to be purchased
by it.

            Section 1.3 Other Subscribers. Prior to any Closing hereunder, the
Company will offer all of its members, in accordance with the provisions of
Section 4.1(e) of its Bye-Laws or otherwise, the right to subscribe for Common
Shares (as defined below) of the Company in the Offering. All such members
(other than the Major Investors) will be entitled to ten (10) business days
advance notice of the price of the Securities to be purchased in the Offering
before they are required to make an investment decision. The Company agrees that
any such member who does not subscribe for its pro rata portion of the Offering
will not be entitled to, or granted a right to, sell Common Shares in the
Company's initial public offering, without the prior written consent of the
Company and the Qualified Sponsors.

                                   ARTICLE II

                                     CLOSING

            The closing of the purchase and sale of the Securities contemplated
by this Agreement (the "Closing") shall take place as set forth below.

            Section 2.1 Closing Date. On the basis of the representations and
warranties hereinafter set forth and subject to the conditions hereinafter set
forth, the Company will sell to the Major Investors, and each Major Investor
(acting severally and not jointly) will purchase from the Company, at the
Closing on the Closing Date its Percentage Commitment of the Common Shares to be
sold to all of the Major Investors on the Closing Date, up to the full dollar
amount of the Securities set forth in Schedule A opposite its name (except as
provided therein), in each case, for a purchase price per Security equal to the
Purchase Price.

            Section 2.2 Payment and Delivery. Subject to the terms and
conditions of this Agreement and on the basis of the representations and
warranties hereinafter set forth, (A) at the Closing, each Major Investor
(acting severally and not jointly) will deliver to the Company full payment of
its Purchase Price for the Securities to be purchased by it by wire transfer of
immediately available funds and (B) at the Closing, the Company shall cause each
Major Investor's name to be entered in the register of shareholders of Common
Shares against payment of its Purchase Price, and shall deliver to such Major
Investor, within three (3) business days of the Closing Date, duly executed
certificates evidencing the Securities, in each case, registered in the name of
such Major Investor (or its nominee(s) as set forth on such Major Investor's
signature page).

                                   ARTICLE III

              REPRESENTATIONS AND WARRANTIES OF THE MAJOR INVESTORS

            Each Major Investor for itself (and not any other Major Investor)
hereby represents and warrants to the Company as of the date hereof and as of
immediately prior to the Closing on the Closing Date as follows:

                                      -2-
<PAGE>

            Section 3.1 Organization and Standing. The Major Investor is either
an individual or a corporation (including any similar entity formed under the
laws of a jurisdiction outside the U.S.), government instrumentality or
partnership or limited liability company taxed as a partnership for U.S. federal
income tax purposes or trust (and where such partnership or trust is not a
separate legal entity from, as the case may be, the partners or beneficiaries
thereof, the general or managing partner or trustee, as applicable, thereof is)
duly organized, validly existing and in good standing under the laws of its
jurisdiction of organization.

            Section 3.2 Authorization. This Agreement has been duly authorized,
executed and delivered by the Major Investor and, assuming due authorization,
execution and delivery by the Company, constitutes a legal, valid and binding
obligation of the Major Investor enforceable against the Major Investor in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally and by
general equitable principles (regardless of whether such enforceability is
considered in a proceeding at equity or at law).

            Section 3.3 Investment Intent. The Major Investor is acquiring the
Securities for its own account or for one or more separate accounts maintained
by it or for the account of one or more pension or trust funds of which it is
trustee, in each case, for investment purposes only and not with a view to
distribution thereof, in whole or in part. If the Securities are acquired for
the account of one or more pension or trust funds, the Major Investor represents
that it is acting as sole trustee and has sole investment discretion with
respect to its acquisition of the Securities and that the determination and
decision on its behalf to acquire the Securities for such pension or trust funds
is being made by the same individual or group of individuals who customarily
pass on such investments, so that the Major Investor's decision as to
acquisitions for all such funds is the result of one study and conclusion. The
Major Investor has advised the Company in writing of its form of organization
and the accounts for which it is purchasing, as applicable, and all such
information provided to the Company is true and correct as of the date hereof.

            Section 3.4 Investor Awareness.  The Major Investor is aware and
agrees and acknowledges that:

            (a) neither the Securities nor the underlying common shares have
      been registered under the Securities Act of 1933, as amended (the
      "Securities Act"), or under any federal, foreign, state or other
      jurisdiction's securities laws; the transfer thereof is restricted by the
      Securities Act and applicable securities laws; and the Company is under no
      obligation to, and currently does not intend to, register or qualify the
      Securities for resale by the Major Investor or assist the Major Investor
      in complying with any exemption under the Securities Act or the securities
      laws of any such jurisdiction or any other jurisdiction. An offer or sale
      directly or indirectly of Securities by the Major Investor will be subject
      to the terms and provisions of this Agreement, the Certificate of
      Designations with respect to the Common Shares and the Bye-laws and, in
      the absence of registration under the Securities Act, will require the
      availability of an exemption thereunder and an opinion of counsel of the
      Major Investor that is reasonably acceptable to the Company regarding the
      availability of such exemption. Subject to the Bye-laws and this
      Agreement, certificates representing Securities will contain a restrictive
      legend reflecting such restrictions.

            (b) The Major Investor is acquiring the Securities for his or her
      own account, for investment only and not with a view toward the transfer,
      resale or distribution thereof in violation of any applicable securities
      law.

            Section 3.5 Accredited Investor. The Major Investor is, and at the
time of the offer by the Company to sell the Securities and at the time of such
Major Investor's purchase of the Securities

                                      -3-
<PAGE>

will be, an "accredited investor," as that term is defined in Rule 501(a) of
Regulation D under the Securities Act (a copy of the definition of "accredited
investor" is attached hereto as Schedule B).

            Section 3.6 Brokers or Finders. The Major Investor has not incurred,
nor will it incur, directly or indirectly, as a result of any action taken by
the Major Investor, any liability for brokerage or finders' fees or agents'
commissions or any similar charges in connection with this Agreement and the
transactions contemplated hereby.

            Section 3.7 Maximum Major Investor's Holdings. To the best knowledge
of the Major Investor, it is not acquiring the Securities pursuant to this
Agreement that would cause (after giving effect to the operation of Section 4.3
of the Bye-laws) the Major Investor, if a U.S. Person (as defined below), to
own, directly, indirectly or constructively, or cause another U.S. Person that
is a Beneficial Owner (as defined below) to own, directly, indirectly or
constructively, more than (i) 9.09% of the voting power of the Company's issued
and outstanding shares of stock or (ii) 24.5% of the Company's issued and
outstanding shares of stock. As used in this Section 3.7, the term "Beneficial
Owner" means any person that owns stock or warrants of the Company directly or
indirectly; references to "direct, indirect or constructive ownership" includes
ownership within the meaning of Sections 958(a) and Section 958(b) of the
Internal Revenue Code of 1986, as amended (the "Code") and references to "direct
or indirect ownership" includes ownership within the meaning of Section 958(a)
of the Code (but not Section 958(b) of the Code). The term "U.S. Person" means
(i) an individual who is a citizen or resident of the United States, (ii) a
corporation or partnership that is, as to the United States, a domestic
corporation or a domestic partnership, (iii) an estate or trust that is subject
to U.S. federal income tax on its income regardless of its source, or (iv) the
United States and the states thereof, including any of their political
subdivisions.

            The Company represents and warrants to each Major Investor that, for
purposes of such Major Investor's calculation of its total percentage ownership,
the total number of Common Shares issued and outstanding as of June 30, 2007 is
59,236,096. The Company agrees that, notwithstanding any other provision of this
Agreement, no Major Investor, together with its affiliates, shall be required to
purchase securities pursuant to this Agreement which would result in such Major
Investor, together with its affiliates, owning, directly or indirectly, or
constructively, more than 24.500% of the Company's issued and outstanding shares
of stock or otherwise exceeding the ownership limitations set forth in the first
sentence of the preceding paragraph of this Section 3.7, with any Common Shares
not being purchased pursuant to this paragraph being allocated to and purchased
by the other Major Investors.

                                   ARTICLE IV

                             CONDITIONS TO PURCHASE

                                    ARTICLE V

                                  MISCELLANEOUS

            Section 5.1 Termination. The several obligations of each Major
Investor shall terminate on the earlier of (i) consummation of one or more

has been duly delivered before any such termination the several obligation of
each Major Investor to purchase Securities shall continue until satisfied.

            Section 5.2 NASD Matters. The Company hereby agrees (for the benefit
of each Major Investor who is affiliated with an NASD member who is or would be
an underwriter of any initial public offering of securities of the Company as
well for the benefit of each such underwriter), that to the extent the
acquisition of Common Shares hereunder would result in underwriter's
compensation to such underwriter in excess of the applicable maximum amount
permitted by NASD Rule 2710 (after discussion with the NASD staff), the Company
will endeavor to purchase, or if it cannot so purchase, cause the purchase of,
such shares so purchased hereunder at the price paid hereunder, to the extent
necessary to avoid or eliminate such excess.

            Section 5.3 Other. The representations and warranties of the parties
contained in this Agreement shall survive the Closing. The parties have made no
representations or warranties other than those that are expressly set forth in

            4.    Rights Attaching to Shares

            4.1 Subject to Bye-law 2 and the Memorandum of Association, the
      holders of the Common Stock shall, subject to the provisions of the
      Bye-laws....

                  (e) have a right of first refusal (the "Preemptive Right") to
            purchase any New Securities that the Company may, from time to time,
            propose to issue and sell. Such Preemptive Right shall allow each
            Member to purchase New Securities proposed to be issued and sold by
            the Company in an amount determined in accordance with Bye-law
            4.1(e)A described below.

                        A. In the event that the Company proposes to undertake
                  an issuance or sale of New Securities, it shall give each
                  Member written notice of its intention (the "New Issue
                  Notice"), describing the type and number of New Securities it
                  intends to issue, the purchase price therefor (which shall be
                  payable solely in cash by a Member), and the terms and
                  conditions upon which the Company proposes to issue the same.
                  Each Member shall have five (5) Business Days following the
                  date the New Issue Notice is received by such Member to
                  determine whether to purchase all or any portion of such New
                  Securities for the purchase price and upon the terms and
                  conditions specified in the New Issue Notice by giving written
                  notice to the Company (a "Preemptive Rights Notice"), stating
                  therein the number of New Securities such Member is
                  subscribing to purchase (which shall not, in any event, exceed
                  the number of New Securities proposed to be issued), which
                  Preemptive Rights Notice shall be binding on such Member. If
                  Members subscribe for an aggregate amount of New Securities in
                  excess of the number of New Securities proposed to be issued
                  and sold by the Company as described in the New Issue Notice,
                  each Member exercising its Preemptive Right will be allocated
                  (a) first, a number of New Securities equal to the lesser of
                  (x) the number of New Securities requested by such Member and
                  (y) such Member's Pro Rata Portion of the New Securities
                  proposed to be issued, and (b) second, with respect to any
                  remaining New Securities, a number of New Securities equal to
                  (x) such Member's Pro Rata Portion of such remaining New
                  Securities or (y) if the remaining number of New Securities
                  requested by such Member is less than the number in clause
                  (b)(x), the remaining number of New Securities requested by
                  such Member. The calculation in clause (b) of the preceding
                  sentence shall be repeated as necessary until all New
                  Securities have been allocated. Each Member that on the date
                  of such New Issue Notice owns Non-Voting Common Stock shall be
                  entitled at its option to receive any New Securities it may
                  purchase pursuant to a Preemptive Right in the form of a
                  non-voting security, which security shall be identical to the
                  New Securities except that such security shall have rights
                  substantially similar to those set forth in Bye-law 4.1A, with
                  such other changes as are appropriate to make such non-voting
                  security substantially identical to the

                                    Annex A-1

<PAGE>

                  New Securities. Any such non-voting security shall have
                  provisions to convert such security to a voting security
                  otherwise substantially ide t 18 ntical thereto, which
                  conversion provisions shall be substantially identical to the
                  conversion provisions contained in Bye-law 4.1C and 4.1D.
                  References in this Bye-law 4.1(e) to "New Securities" shall
                  include such non-voting securities, to the extent applicable.
                  For the avoidance of doubt, the Company shall not be under any
                  obligation to issue or sell any of the New Securities proposed
                  to be issued or sold in any New Issue Notice.

                        B. If the Members have not agreed to purchase all or any
                  portion of the New Securities to be issued in accordance with
                  the terms of any New Issue Notice and the provisions of
                  Bye-law 4.1(e)(A), then the Company shall have the right to
                  issue and sell all such New Securities not agreed to be
                  purchased by the Members pursuant to Bye-law 4.1(e)(A) (the
                  "Remaining New Securities") at a price no less than that
                  contained in the New Issue Notice and on non-price terms no
                  less favorable (taken as a whole) to the Company than those
                  contained in the New Issue Notice; provided that (i) the
                  Company has fully complied with the provisions of Bye-law
                  4.1(e) and (ii) such issuance and sale of Remaining New
                  Securities is consummated by the Company within 90 days after
                  the sending of the New Issue Notice to the Members pursuant to
                  Bye-law 4.1(e)(A) hereof, provided that, if such issue is
                  subject to regulatory approval, such 90-day period shall be
                  extended until the expiration of five (5) business days after
                  such approvals have been received, but in no event later than
                  180 days from the date of the New Issue Notice. In the event
                  that the issuance and sale of the Remaining New Securities is
                  not fully consummated by the Company prior to the end of such
                  period, the provisions of Bye-law 4.1(e) must be again be
                  complied with by the Company before the Company may issue or
                  sell any additional New Securities.

                        C.    Notwithstanding anything contained in Bye-law
                  4.1(e) to the contrary, the purchase price for any New
                  Security shall be determined by the Board.

                        D.    This Bye-law 4.1(e) shall terminate upon the
                  First Public Offering.
