          Section 1.2 Compliance Certificates and Opinions. Upon any application
or request by the Company to the Trustee to take any action under any provision
of this Indenture, the Company shall furnish to the Trustee an Officers'
Certificate stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with and an Opinion
of Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with, except that in the case of any such
application or request as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (including certificates provided for in
Section 10.8) shall include:

          (a) a statement that each individual signing such certificate or
opinion has read such covenant or condition and the definitions herein relating
thereto;

          (b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based;

          (c) a statement that, in the opinion of each such individual, he has
made such examination or investigation as is necessary to enable him to express
an informed opinion as to whether or not such covenant or condition has been
complied with; and

          (d) a statement as to whether, in the opinion of each such individual,
such condition or covenant has been complied with.

          Section 1.3 Form of Documents Delivered to the Trustee. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons

                                       14


as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

     Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company or any other Person
stating that the information with respect to such factual matters is in the
possession of the Company or such other Person, unless such counsel knows, or in
the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

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

          Section 1.4 Acts of Holders of Securities. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Indenture to be given or taken by Holders of Securities may be
embodied in and evidenced by (i) one or more instruments of substantially
similar tenor signed by such Holders in person or by an agent or proxy duly
appointed in writing by such Holders or (ii) the record of Holders of Securities
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities duly called and held in
accordance with the provisions of Article IX. Such action shall become effective
when such instrument or instruments or record is delivered to the Trustee and,
where it is hereby expressly required, to the Company. The Trustee shall
promptly deliver to the Company copies of all such instruments and records
delivered to the Trustee. Such instrument or instruments and records (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders of Securities signing such instrument or instruments
and so voting at such meeting. Proof of execution of any such instrument or of a
writing appointing any such agent or proxy, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 6.1) conclusive in favor of the Trustee and the Company if made in the
manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 9.6.

          (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 a certificate of a 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 the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.

          (c) The principal amount and serial number of any Security held by any
Person, and the date of his holding the same, shall be proved by the Security
Register.

                                       15


          (d) The fact and date of execution of any such instrument or writing
and the authority of the Person executing the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

          (e) The Company may set any day as the record date for the purpose of
determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted by this Indenture to be given or taken by
Holders. Promptly and in any case not later than ten days after setting a record
date, the Company shall notify the Trustee and the Holders of such record date.
If not set by the Company prior to the first solicitation of a Holder made by
any Person in respect of any such action, or, in the case of any such vote,
prior to such vote, the record date for any such action or vote shall be the
30th day (or, if later, the date of the most recent list of Holders required to
be provided pursuant to Section 14.1) prior to such first solicitation or vote,
as the case may be. With regard to any record date, the Holders on such date (or
their duly appointed agents or proxies), and only such Persons, shall be
entitled to give or take, or vote on, the relevant action, whether or not such
Holders remain Holders after such record date. Notwithstanding the foregoing,
the Company shall not set a record date for, and the provisions of this
paragraph shall not apply with respect to, any notice, declaration or direction
referred to in the next paragraph.

     Upon receipt by the Trustee from any Holder of (i) any notice of default or
breach referred to in Section 5.1(a)(vii), if such default or breach has
occurred and is continuing and the Trustee shall not have given such a notice to
the Company, (ii) any declaration of acceleration referred to in Section 5.1(b),
if an Event of Default has occurred and is continuing and the Trustee shall not
have given such a declaration to the Company, or (iii) any direction referred to
in Section 5.12, if the Trustee shall not have taken the action specified in
such direction, then, with respect to clauses (ii) and (iii), a record date
shall automatically and without any action by the Company or the Trustee be set
for determining the Holders entitled to join in such declaration or direction,
which record date shall be the close of business on the tenth day (or, if such
day is not a Business Day, the first Business Day thereafter) following the day
on which the Trustee receives such declaration or direction, and, with respect
to clause (i), the Trustee may set any day as a record date for the purpose of
determining the Holders entitled to join in such notice of default. Promptly
after such receipt by the Trustee of any such declaration or direction referred
to in clause (ii) or (iii), and promptly after setting any record date with
respect to clause (i), and as soon as practicable thereafter, the Trustee shall
notify the Company and the Holders of any such record date so fixed. The Holders
on such record date (or their duly appointed agents or proxies), and only such
Persons, shall be entitled to join in such notice, declaration or direction,
whether or not such Holders remain Holders after such record date; provided
that, unless such notice, declaration or direction shall have become effective
by virtue of Holders of the requisite principal amounts of Securities on such
record date (or their duly appointed agents or proxies) having joined therein on
or prior to the 90th day after such record date, such notice, declaration or
direction shall automatically and without any action by any Person be canceled
and of no further effect. Nothing in this paragraph shall be construed to
prevent a Holder (or a duly appointed agent or proxy thereof) from giving,
before or after the expiration of such 90-day period, a notice, declaration or
direction contrary to or different from, or, after the expiration of such
period, identical to, the notice, declaration or direction to which such record
date relates, in

                                       16


which event a new record date in respect thereof shall be set pursuant to this
paragraph. In addition, nothing in this paragraph shall be construed to render
ineffective any notice, declaration or direction of the type referred to in this
paragraph given at any time to the Trustee and the Company by Holders (or their
duly appointed agents or proxies) of the requisite principal amounts of
Securities on the date such notice, declaration or direction is so given.

          (f) Except as provided in Sections 5.12 and 5.13, any request, demand,
authorization, direction, notice, consent, election, waiver or other Act of 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.

          (g) The provisions of this Section are subject to the provisions of
Section 9.5.

          Section 1.5 Notices, Etc. to the Trustee and Company. Any request,
demand, authorization, direction, notice, consent, election, waiver or other Act
of Holders of Securities or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with:

          (a) the Trustee by any Holder of Securities or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with a Responsible Officer of the Trustee and received at its
Corporate Trust Office; and

          (b) the Company by the Trustee or by any Holder of Securities shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing, mailed, first-class postage prepaid, or telecopied and
confirmed by mail, first-class postage prepaid, or delivered by hand or
overnight courier, addressed to the Company at 11825 N. Pennsylvania Street,
Carmel, Indiana 46032, Attention: Daniel J. Murphy, Treasurer, or at any other
address previously furnished in writing to the Trustee by the Company.

          Section 1.6 Notice to Holders of Securities; Waiver. (a) Except as
otherwise expressly provided herein, where this Indenture provides for notice to
Holders of Securities of any event, such notice shall be sufficiently given to
Holders if in writing and mailed, first-class postage prepaid or delivered by an
overnight delivery service, or transmitted by telecopy or other electronic
means, with written confirmation of transmission, to each Holder of a Security
affected by such event, at the address of such Holder as it appears in the
Security Register, not earlier than the earliest date and not later than the
latest date prescribed for the giving of such notice.

          (b) Neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder of a Security shall affect the
sufficiency of such notice with respect to other Holders of Securities. In case
by reason of the suspension of regular mail service or by reason of any other
cause it shall be impracticable to give such notice by mail, then such
notification to Holders of Securities as shall be made with the approval of the
Trustee, which approval shall not be unreasonably withheld, shall constitute a
sufficient notification to such Holders for every purpose hereunder.

                                       17


          (c) Such notice shall be deemed to have been given three days after
mailing, if by mail, one day after mailing if by overnight courier, and on the
date the notice is furnished if by telecopy or other electronic means or by
hand.

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

          Section 1.8 Successors and Assigns. All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

          Section 1.9 Separability Clause. In case 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.

          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 hereunder and the Holders of
Securities, any benefit or legal or equitable right, remedy or claim under this
Indenture.

          Section 1.11 Governing Law. THIS INDENTURE AND THE SECURITIES SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          Section 1.12 Legal Holidays. In any case where any Interest Payment
Date, Redemption Date, Repurchase Date or Stated Maturity of any Security or the
last day on which a Holder of a Security has a right to convert his Security
shall not be a Business Day at a Place of Payment or Place of Conversion, as the
case may be, then (notwithstanding any other provision of this Indenture or of
the Securities) payment of principal amount of or Interest on, or the payment of
the Redemption Price or Repurchase Price (whether the same is payable in cash or
in shares of Common Stock or a combination of cash and stock in the case of the
Repurchase Price) with respect to, or delivery for conversion of, such Security
need not be made at such Place of Payment or Place of Conversion, as the case
may be, on or by such day, but may be made on or by the next succeeding Business
Day at such Place of Payment or Place of Conversion, as the case may be, with
the same force and effect as if made on the Interest Payment Date, Redemption
Date or Repurchase Date, or at the Stated Maturity or by such last day for
conversion; provided, however, that in the case that payment is made on such
succeeding Business Day, no Interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date,
Repurchase Date, Stated Maturity or last day for conversion, as the case may be.

                                       18


          Section 1.13 Conflict with Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act that is required under such Act to be a part of and govern this Indenture,
the latter provision shall control. If any provision of this Indenture modifies
or excludes any provision of the Trust Indenture Act that may be so modified or
excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be. Until such time as this
Indenture shall be qualified under the Trust Indenture Act, this Indenture, the
Company and the Trustee shall be deemed for all purposes hereof to be subject to
and governed by the Trust Indenture Act to the same extent as would be the case
if this Indenture were so qualified on the date hereof.

     Payments on the Securities will be made in U.S. dollars at the office of
the Trustee; provided that the Company may elect to make payments by check
mailed to the Holder's registered address or, with respect to Global Securities,
by wire transfer.

     In the event any Holder surrenders any Security for conversion during the
period between the close of business on a Record Date but prior to the
corresponding Interest Payment Date, the Company shall pay accrued Interest on
such Security on that Interest Payment Date to the Holder of such Security as of
such Record Date. However, the Holder surrendering the Security for conversion
shall be required to pay to the Company an amount equal to the Interest that has
accrued as of such Interest Payment Date and that amount will be paid to the
Holder of such Security as of the Record Date pursuant to the preceding
sentence. Notwithstanding the foregoing, the preceding sentence does not apply
to Securities that are surrendered for conversion after the Company has
specified a Redemption Date that is after a Record Date but on or prior to the
corresponding Interest Payment Date.

     The Company agrees, and by acceptance of a beneficial ownership in the
Securities each Holder of the Securities has agreed, for United States federal
income tax purposes, (a) to treat the Securities as "contingent payment debt
instruments" as defined in Treasury Regulations Section 1.1275-4 (the
"Contingent Payment Regulations") and, for purposes of the Contingent Payment
Regulations, to treat the Fair Market Value of any Common Stock beneficially
received by a beneficial owner upon conversion of the Securities as a contingent
payment; (b) to accrue interest with respect to the Securities as original issue
discount on a constant yield basis using the comparable yield of 7.375% per
annum compounded semi-annually; and (c) to be bound by the "comparable yield"
and the "projected payment schedule" within the meaning of the Contingent
Payment Regulations, as determined by the Company. A Holder or beneficial owner
of Securities may obtain the issue price, issue date, comparable yield and
projected payment schedule by submitting a written request to the Company at the
following address: Conseco Inc., 11825 N. Pennsylvania Street, Carmel, Indiana
46032, Attention: Investor Relations.

                                       24


     Except as specifically provided herein and in the Indenture, the Company
shall not be required to make any payment with respect to any tax, assessment or
other governmental charge imposed by any government or any political subdivision
or taxing authority thereof or therein.

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

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof or an Authenticating Agent by the
manual signature of one of their respective authorized signatories, this
Security shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

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

                                    CONSECO, INC.


                                    By:________________________
                                             Name:
                                             Title:

                                       25


                                [FORM OF REVERSE]

     This Security is one of a duly authorized issue of securities of the
Company designated as its "3.50% Convertible Debentures due September 30, 2035"
(herein called the "Securities"), limited in aggregate principal amount to U.S.
$330,000,000, issued and to be issued under an Indenture, dated as of August 15,
2005 (herein called the "Indenture"), between the Company and The Bank of New
York Trust Company, N.A., as Trustee (herein called 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 and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities are convertible into Conversion Consideration.

     No sinking fund is provided for the Securities.

     The Securities are subject to redemption at the option of the Company at
any time on or after October 5, 2010, in whole or in part, upon not less than 30
nor more than 60 days' notice to the Holders prior to the Redemption Date at a
Redemption Price equal to 100% of the Accreted Principal Amount, plus accrued
and unpaid interest (including Regular Interest, Contingent Interest, and
Additional Interest, as applicable, together "Interest") to, but excluding, the
Redemption Date.

     In the event of a redemption of the Securities, the Company will not be
required (a) to register the transfer or exchange of any Security for a period
beginning at the opening of business 15 days immediately preceding the mailing
of a Redemption Notice and ending on the close of business on the day of such
mailing or (b) to register the transfer or exchange of any Security, or portion
thereof, called for redemption (except the unredeemed portion of a Security
being redeemed in part).

     Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled to require the Company to repurchase this
Security on September 30, 2010, 2015, 2020, 2025 and 2030. The repurchase price
payable on any Repurchase Date will be equal to 100% of the Accreted Principal
Amount of the Securities to be repurchased, plus accrued and unpaid Interest to,
but not including, the applicable Repurchase Date.

     A Holder may withdraw any repurchase notice by delivering a written notice
of withdrawal to the Paying Agent prior to the close of business on the second
Business Day immediately preceding the Repurchase Date. The notice of withdrawal
must state: (i) the principal amount of the Securities being withdrawn; (ii) if
certificated, the certificate numbers of the Securities being withdrawn; and
(iii) the Initial Principal Amount of the Securities that remain subject to the
Repurchase Notice.

     If this Security is a Registrable Security (as defined in the Indenture),
then the Holder of this Security [if this security is a global security, then
insert - (including any Person that has a beneficial interest in this Security)]
and the Common Stock of the Company issuable upon

                                       26


conversion hereof is entitled to the benefits of a Registration Rights
Agreement, dated as of August 15, 2005 (the "Registration Rights Agreement"),
between the Company and the Initial Purchasers. Pursuant to the Registration
Rights Agreement, the Company has agreed for the benefit of the Holders from
time to time of the Registrable Securities that it will, at its expense, among
other things, and as more fully provided in such agreement, file a shelf
registration statement (the "Shelf Registration Statement") with the Commission
with respect to resales of the Registrable Securities and maintain such Shelf
Registration Statement effective under the Securities Act for a specified period
(the "Effectiveness Period"). The Company will be permitted to suspend the use
of the prospectus which is part of the Shelf Registration Statement during
certain periods of time as provided in the Registration Rights Agreement.

     If (a) on or prior to the 90th day following August 15, 2005, a Shelf
Registration Statement has not been filed with the Commission, or (b) on or
prior to the 210th day following August 15, 2005, such Shelf Registration
Statement is not declared effective (each, a "Registration Default"), additional
interest ("Additional Interest") will accrue on this Restricted Security from
and including the day following such Registration Default to but excluding the
day on which such Registration Default has been cured. Additional Interest will
be paid semi-annually in arrears, with the first semi-annual payment due on the
first Interest Payment Date, as applicable, in respect of the Restricted
Securities following the date on which such Additional Interest begin to accrue,
and will accrue at a rate per annum equal to one-quarter of one percent (0.25%)
of the principal amount of the Restricted Securities to and including the 90th
day following such Registration Default and at a rate per annum equal to
one-half of one percent (0.50%) thereof from and after the 91st day following
such Registration Default. Pursuant to the Registration Rights Agreement, in the
event that the Shelf Registration Statement ceases to be effective (or the
Holders of Registrable Securities are otherwise prevented or restricted by the
Company from effecting sales pursuant thereto) (an "Effective Failure") during
the Effectiveness Period for more than 30 days, whether or not consecutive,
during any 90-day period or for more than 90 days, whether or not consecutive,
during any 12-month period, then the Additional Interest will accrue at a rate
per annum equal to an additional one-half of one percent (0.50%) of the
principal amount of the Restricted Securities from the 31st day of the
applicable 90-day period or the 91st day of the applicable 12-month period until
the earlier of (i) such time as the Effective Failure is cured or (ii) the
Effectiveness Period expires.

     Whenever in this Security there is a reference, in any context, to the
payment of the principal amount of or Interest on, or in respect of, any
Security, such mention shall be deemed to include mention of the payment of
Additional Interest payable as described in the immediately preceding paragraph
to the extent that, in such context, Additional Interest is, was or would be
payable in respect of such Security and express mention of the payment of
Additional Interest (if applicable) in any provisions of this Security shall not
be construed as excluding Additional Interest in those provisions of this
Security where such express mention is not made.

     If this Security is a Registrable Security and the Holder of this Security
[if this security is a global security, then insert - (including any Person that
has a beneficial interest in this security)] elects to sell this Security
pursuant to the Shelf Registration Statement then, by its acceptance hereof,
such Holder of this Security agrees to be bound by the terms of the Registration
Rights Agreement relating to the Registrable Securities which are the subject of
such election.

                                       27


     [The following paragraph shall appear in each Global Security:

     In the event of a deposit or withdrawal of an interest in this Security,
including an exchange, transfer, redemption, repurchase or conversion of this
Security in part only, the Trustee, as custodian of the Depositary, shall make
an adjustment on its records to reflect such deposit or withdrawal in accordance
with the Applicable Procedures.]

     [The following paragraph shall appear in each Security that is not a Global
Security:

     In the event of redemption, repurchase or conversion of this Security in
part only, a new Security or Securities for the unredeemed, unrepurchased or
unconverted portion hereof will be issued in the name of the Holder hereof.]

     If an Event of Default shall occur and be continuing, the principal amounts
of all the Securities, together with accrued Interest to the date of
declaration, may be declared due and payable in the manner and with the effect
provided in the Indenture. Upon payment (a) of the principal amounts so declared
due and payable, together with accrued Interest to the date of declaration, and
(b) of Interest on any overdue principal and, to the extent permitted by
applicable law, overdue interest, all of the Company's obligations in respect of
the payment of the principal of and Interest on the Securities shall terminate.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with either (a) the written consent of
the Holders of not less than a majority in principal amount of the Securities at
the time Outstanding, or (b) by the adoption of a resolution, at a meeting of
Holders of the Outstanding Securities at which a quorum is present, by the
Holders of at least a majority in aggregate principal amount of the Outstanding
Securities represented and entitled to vote at such meeting. The Indenture also
contains provisions permitting the Holders of specified percentages in principal
amounts of the Securities at the time Outstanding, on behalf of the Holders of
all the 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 in exchange therefor or in lieu hereof
whether or not notation of such consent or waiver is made upon this Security or
such other Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default, the Holders of not less
than 25% in principal amount of the Outstanding Securities shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee, the Holder or Holders shall have offered indemnity
satisfactory to the Trustee, the Trustee shall not have received from the
Holders of a majority in principal amount of the Securities Outstanding a
direction inconsistent with such request, and the Trustee shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity. The

                                       28


foregoing shall not apply to any suit instituted by the Holder of this Security
for the enforcement of any payment of principal amount hereof or Interest hereon
on or after the respective due dates expressed herein or for the enforcement of
the right to convert this Security as provided in the Indenture.

     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 amount of and Interest on this
Security at the times, places and rate, and in the coin or currency, herein
prescribed or to convert this Security as provided in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable on the Security Register
upon surrender of this Security for registration of transfer at the Corporate
Trust Office of the Trustee or at such other office or agency of the Company as
may be designated by it for such purpose in the Borough of Manhattan, The City
of New York (which shall initially be an office or agency of the Trustee), or at
such other offices or agencies as the Company may designate, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder thereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees by the Registrar. 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 recover any tax or other
governmental charge payable in connection therewith.

     Prior to due presentation of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner thereof for all
purposes, whether or not such Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     No recourse for the payment of the principal amount of or Interest on this
Security and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, employee, agent, officer or
director or subsidiary, as such, past, present or future, of the Company or of
any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of consideration for the
issue hereof, expressly waived and released.

     THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture. In the event of a conflict
between this Security and the Indenture, the terms of the Indenture shall
govern.

XIII of this Indenture and the Repurchase Price shall be payable at such places
as are identified in the notice of the Company given pursuant to Section 13.1
(any city in which any Paying Agent is located being herein called a "Place of
Payment").

          (f) The Registrable Securities are entitled to the benefits of a

                                       34


          (b) In the event that any Interest becomes payable on the Securities,
a Holder of any Security at the close of business on a Record Date shall be
entitled to receive such Interest on the corresponding Interest Payment Date;
provided, however, that:

          (i) Subject to Section 12.6, the Company will not pay accrued Interest
on Securities surrendered for conversion and upon payment by or on behalf of the
Company of the Conversion Consideration with respect thereto the Company shall
satisfy its obligations with respect to the Securities, including the payment of
the principal amount and any such accrued Interest, such amounts being deemed to
have been paid in full rather than cancelled, extinguished or forfeited by
receipt of Conversion Consideration; provided that, Additional Interest will be
payable as specified in the Registration Rights Agreement and this Indenture;
and

          (ii) all Interest will be paid to a Person other than the Holder of a
Security on a Record Date if the Company redeems the Security on a date that is
after such Record Date and on or prior to the corresponding Interest Payment
Date, in which case accrued and unpaid Interest on the Security being redeemed
to, but excluding, the Redemption Date will be paid to the same Person to whom
the principal amount of such Security is paid.

          (c) Except as provided below, the Company will pay Interest on:

          (i) any Global Security to the Depositary therefor in immediately
available funds; and

          (ii) any certificated Securities by check mailed to the Holders of
those Securities.

          (d) At maturity, Interest on any certificated Securities will be
payable at the office of the Trustee.

          (e) Payments on the Securities will be made in U.S. dollars at the

check mailed to the Holder's registered address or, with respect to Global
Securities, by wire transfer in immediately available funds.

          Section 3.3 Denominations. The Securities shall be issuable only in
registered form, without coupons, in denominations of U.S. $1,000 Initial
Principal Amount and integral multiples of U.S. $1,000 in excess thereof.

          Section 3.4 Execution, Authentication, Delivery and Dating. (a) The
Securities shall be executed on behalf of the Company by its Chairman of the
Board, its President or Chief Executive Officer, or one of its Vice Presidents.
Any such signature may be manual or facsimile.

          (b) Securities bearing the manual or facsimile signature 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.

                                       35


          (c) At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities executed by the Company to
the Trustee or to its order for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with such Company Order shall authenticate and make available for
delivery such Securities as in this Indenture provided.

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

          (e) 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 manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

          Section 3.5 Global Securities; Non-global Securities; Book-entry
Provisions. Global Securities. (a) (a) Each Global Security authenticated 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.

          (b) Except for exchanges of Global Securities for definitive,
non-Global Securities at the sole discretion of the Company, no Global Security
may be exchanged in whole or in part for Securities registered, 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 (A) has notified the Company that it is unwilling,
unable or no longer qualified to continue as Depositary for such Global Security
or (B) has ceased to be a clearing agency registered as such under the Exchange
Act or announces an intention permanently to cease business or does in fact do
so or (ii) there shall have occurred and be continuing an Event of Default with
respect to such Global Security. In the event clause (i)(A) of the immediately
preceding sentence is applicable, if a successor Depositary for such Global
Security is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company will
execute, and the Trustee, upon receipt of a Company Order, accompanied by an
Officers' Certificate, directing the authentication and delivery of Securities,
will authenticate and deliver, Securities, in any authorized denominations in an
aggregate principal amount equal to the principal amount of such Global Security
in exchange for such Global Security.

          (c) If any Global Security is to be exchanged for other Securities or
canceled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Trustee, as Security Registrar, for exchange or cancellation,
as provided in this Article III. 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, in each
case, as provided in Section 3.6, 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 the portion thereof to be so exchanged or canceled, or equal to 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

                                       36


of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with
the Applicable 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, the Trustee shall authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered in such names as may be
directed by, the Depositary or its authorized representative. Upon the request
of the Trustee in connection with the occurrence of any of the events specified
in the preceding paragraph, the Company shall promptly make available to the
Trustee a reasonable supply of Securities that are not in the form of Global
Securities. The Trustee shall, subject to Section 3.6(h), be entitled to rely
upon any order, direction or request of the Depositary or its authorized
representative which is given or made pursuant to this Article III if such
order, direction or request is given or made in accordance with the Applicable
Procedures.

          (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, whether pursuant to this Article III or otherwise, shall be
authenticated and delivered in the form of, and shall be, a registered 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, in which case such
Security shall be authenticated and delivered in definitive, fully registered
form, without interest coupons.

          (e) The Depositary or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under the
Indenture and the Securities, and owners of beneficial interests in a Global
Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will 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 Agent Members and
such owners of beneficial interests in a Global Security will not be considered
the owners or holders thereof.

Non-global Securities. Securities issued upon the events described in Section
3.5(b) shall be in definitive, fully registered form, without interest coupons,
and shall bear the Restricted Securities Legend if and as required by this
Indenture.

          Section 3.6 Registration; Registration of Transfer and Exchange;
Restrictions on Transfer. (a) The Company shall cause to be kept at the
Corporate Trust Office of the Trustee a register (the register maintained in
such office referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers and exchanges of Securities as herein provided.

          (b) Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 10.2 for such
purpose, the Company shall execute, and, upon receipt of a Company Order, the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities of any authorized denominations and
of a like aggregate principal amount and bearing such restrictive legends as may
be required by this Indenture.

                                       37


          (c) At the option of the Holder, and subject to the other provisions
of this Section, Securities may be exchanged for other Securities of any
authorized denomination and of a like aggregate principal amount, upon surrender
of the Securities to be exchanged at any such office or agency. Whenever any
Securities are so surrendered for exchange, and subject to the other provisions
of this Section, the Company shall execute and, upon receipt of a Company Order,
the Trustee shall authenticate and deliver, the Securities that the Holder
making the exchange is entitled to receive. Every Security presented or
surrendered for registration of transfer or for exchange shall (if so required
by the Company or the Security Registrar) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company, the
Trustee and the Security Registrar duly executed, by the Holder thereof or his
attorney duly authorized in writing.

          (d) All Securities issued upon any registration of 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 registration of transfer or exchange.

          (e) No service charge shall be charged to a Holder for any
registration of transfer or exchange of Securities except as provided in Section
3.7, 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
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 3.5, 3.6, 3.7, 8.5, 12.5 or 12.6 (other than where the
shares of Common Stock are to be issued or delivered in a name other than that
of the Holder of the Security) not involving any transfer and other than any
stamp and other duties, if any, which may be imposed in connection with any such
transfer or exchange by the United States or any political subdivision thereof
or therein, which shall be paid by the Company.

          (f) In the event of a redemption of the Securities, neither the
Company nor the Securities Registrar will be required (i) to register the
transfer or exchange of any Security for a period of beginning at the opening of
business 15 days immediately preceding the mailing of a Redemption Notice and
ending on the close of business on the day of such mailing or (ii) to register
the transfer or exchange of any Security, or portion thereof, called for
redemption (except the unredeemed portion of a Security being redeemed in part).

          (g) Certain Transfers and Exchanges. Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section shall be made only in accordance with this Section.

          (i) Restricted Global Security to Restricted Non-Global Security. In
the event that non-Global Securities are to be issued pursuant to Section 3.5(b)
in connection with any transfer of Securities, such transfer may be effected
only in accordance with the provisions of this clause and subject to the
Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of
(A) a Company Order from the Company directing the Trustee, as Security
Registrar, to (x) authenticate and deliver one or more Securities of the same
aggregate principal amount as the beneficial interest in the Restricted Global
Security to be transferred, such instructions to contain the name or names of
the designated transferee or transferees, the

                                       38


authorized denomination or denominations of the Securities to be so issued and
appropriate delivery instructions and (y) decrease the beneficial interest of a
specified Agent Member's account in a Restricted Global Security by a specified
principal amount not greater than the principal amount of such Restricted Global
Security, and (B) such other certifications, legal opinions or other information
as the Company or the Trustee may reasonably require to confirm that such
transfer is being made pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act, then the
Trustee, as Security Registrar, shall decrease the principal amount of the
Restricted Global Security by the specified amount and authenticate and deliver
Securities in accordance with such instructions from the Company as provided in
Section 3.5(c).

          (ii) Restricted Non-Global Security to Restricted Global Security. If
the Holder of a Restricted Security (other than a Global Security) wishes at any
time to transfer all or any portion of such Restricted Security to a Person who
wishes to take delivery thereof in the form of a beneficial interest in the
Restricted Global Security, such transfer may be effected only in accordance
with the provisions of this clause and subject to the Applicable Procedures.
Upon receipt by the Trustee, as Security Registrar, of such Restricted Security
as provided in this Section and instructions from the Company directing that a
beneficial interest in the Restricted Global Security in a specified principal
amount not greater than the principal amount of such Security be credited to a
specified Agent Member's account, then the Trustee, as Security Registrar, shall
cancel such Restricted Security (and issue a new Restricted Security in respect
of any untransferred portion thereof) as provided in this Section and increase
the principal amount of the Restricted Global Security by the specified
principal amount as provided in Section 3.5(c).

          (iii) Exchanges Between Global Security and Non-global Security. A
beneficial interest in a Global Security may be exchanged for a Security that is
not a Global Security only as provided in Section 3.5(b); provided that, if such
interest is a beneficial interest in the Restricted Global Security, then such
interest shall be exchanged for a Restricted Security (subject in each case to
clause (h) below. A Security that is not a Global Security may be exchanged for
a beneficial interest in a Global Security only if such exchange occurs in
connection with a transfer effected in accordance with clause (g)(ii) above.

          (h) Securities Act Legends. All Securities issued pursuant to this
Indenture, and all Successor Securities, shall bear the Restricted Securities
Legend and shall be subject to the restrictions on transfer specified therein,
subject to the following:

          (i) subject to the following clauses of this Section, a Security or
any portion thereof which is exchanged, upon transfer or otherwise, for a Global
Security or any portion thereof shall bear the Restricted Securities Legend
borne by such Global Security for which the Security was exchanged;

          (ii) subject to the following clauses of this Section 3.6, a new
Security that is not a Global Security and is issued in exchange for another
Security (including a Global Security) or any portion thereof, upon transfer or
otherwise, shall bear the Restricted Securities Legend borne by the Security for
which the new Security was exchanged;

                                       39


          (iii) any Securities that are sold or otherwise disposed of pursuant
to an effective registration statement under the Securities Act (including the
Shelf Registration Statement), together with their Successor Securities shall
not bear a Restricted Securities Legend; the Company shall inform the Trustee in
writing of the effective date of any such registration statement registering the
Securities under the Securities Act and shall notify the Trustee, in writing, at
any time when prospectuses must be delivered with respect to Securities to be
sold pursuant to such registration statement. The Trustee shall not be liable
for any action taken or omitted to be taken by it in good faith in accordance
with the aforementioned registration statement and instructions;

          (iv) at any time after the Securities may be freely transferred
without registration under the Securities Act or without being subject to
transfer restrictions pursuant to the Securities Act, a new Security that does
not bear a Restricted Securities Legend may be issued in exchange for or in lieu
of a Security (other than a Global Security) or any portion thereof that bears
such a legend if the Trustee has received an Unrestricted Securities
Certificate, satisfactory to the Trustee and duly executed by the Holder of such
Security bearing a Restricted Securities Legend or his attorney duly authorized
in writing, and after such date and receipt of such certificate, upon receipt of
a Company Order, the Trustee shall authenticate and deliver such new Security in
exchange for or in lieu of such other Security as provided in this Article III;

          (v) a new Security that does not bear a Restricted Securities Legend
may be issued in exchange for or in lieu of a Security or any portion thereof
that bears such a legend if, in the Company's judgment, placing such a legend
upon such new Security is not necessary to ensure compliance with the
registration requirements of the Securities Act, and the Trustee, at the
direction of the Company, shall authenticate and deliver such a new Security as
provided in this Article III; and

          (vi) notwithstanding the foregoing provisions of this Section 3.6, a
Successor Security of a Security that does not bear a Restricted Securities
Legend shall not bear such legend unless the Company has reasonable cause to
believe that such Successor Security is a "restricted security" within the
meaning of Rule 144, in which case the Trustee, at the direction of the Company,
shall authenticate and deliver a new Security bearing a Restricted Securities
Legend in exchange for such Successor Security as provided in this Article III.

          (i) Any stock certificate representing shares of Common Stock issued
upon conversion of the Securities shall bear the Restricted Securities Legend
borne by such Securities, to the extent required by this Indenture, unless such
shares of Common Stock have been sold pursuant to a registration statement that
has been declared effective under the Securities Act (and that continues to be
effective at the time of such transfer) or sold pursuant to Rule 144(k) of the
Securities Act, or unless otherwise agreed by the Company in writing with
written notice thereof to the transfer agent for the Common Stock. With respect
to the transfer of shares of Common Stock issued upon conversion of the
Securities that are restricted hereunder, any deliveries of certificates, legal
opinions or other instruments that would be required to be made to the Security
Registrar in the case of a transfer of Securities, as described above, shall
instead be made to the transfer agent for the Common Stock.

                                       40


          (j) Neither the Trustee, the Paying Agent nor any of their agents
shall (i) have any duty to monitor compliance with or with respect to any
Federal or state or other securities or tax laws or (ii) have any duty to obtain
documentation on any transfers or exchanges other than as specifically required
hereunder.

          Section 3.7 Mutilated, Destroyed, Lost or Stolen Securities. (a) If
any mutilated Security is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding. If the Holder of such lost, stolen or destroyed
Security delivers to the Company and the Trustee:

          (i) evidence to their satisfaction of the destruction, loss or theft
of any Security, and

          (ii) such security or indemnity as may be satisfactory to the Company
and the Trustee to save each of them and any agent of either of them harmless,
then, in the absence of actual notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and deliver, in lieu of any such lost, stolen
or destroyed Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

          (b) In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security, upon satisfaction of the conditions set forth in the preceding
paragraph.

          (c) Upon the issuance of any new Security under this Section, 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 (other than any
stamp and other duties, if any, which may be imposed in connection therewith by
the United States or any political subdivision thereof or therein, which shall
be paid by the Company) and any other expenses (including the fees and expenses
of the Trustee) connected therewith.

          (d) Every new Security issued pursuant to this Section 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 such new Security shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued
hereunder.

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

          Section 3.8 Regular Interest. Subject to the last paragraph of Section
3.11, "Regular Interest" will accrue on the Securities at the rate of 3.50% per
year during any six-month period from and including March 31 to and including
September 29 and from and including September 30 to and including March 30,
commencing March 31, 2006 (provided that

                                       41


the initial Interest Period shall commence on August 15, 2005 and run to but
excluding March 31, 2006). Regular Interest will be payable in arrears on
September 30 and March 31 of each year (provided, however, that if such date is
not a Business Day, interest will be payable on the next succeeding Business
Day, and no additional interest will accrue therefor), beginning March 31, 2006,
to the Holder of record at the close of business on the Regular Record Date
preceding such Interest Payment Date, provided that the Securities will cease to
accrue Regular Interest as of September 30, 2010.

          Section 3.9 Contingent Interest. (a) The Company will pay Contingent
Interest to Holders during any six-month period from and including March 31 to
and including September 29 or from and including September 30 to and including
March 30 (each, an "Interest Period") beginning with the six-month Interest
Period commencing on September 30, 2010, if the average Trading Price per
Security for the five consecutive Trading Day period immediately preceding the
first day of the relevant Interest Period (the "Measurement Period") equals or
exceeds 120% of the Accreted Principal Amount of that Security as of the last
day of such Measurement Period.

          (b) The amount of "Contingent Interest" payable per Security in any
Interest Period pursuant to this Section shall equal 0.25% of the average
Trading Price per Security for the applicable Measurement Period.

          (c) The Company shall pay Contingent Interest owed pursuant to this
Section for any Interest Period on the Interest Payment Date immediately
succeeding the applicable Interest Period, to Holders of Securities as of the
Regular Record Date related to such Interest Payment Date.

          (d) Upon determination that the Holders of the Securities are entitled
to receive Contingent Interest which may become payable during a relevant
Interest Period, the Company will notify such Holders and the Trustee, will
issue a Press Release containing information regarding the Contingent Interest
determination and will publish the information through a public medium customary
for such Press Releases.

          Section 3.10 Accretion. Beginning on September 30, 2010, the Initial
Principal Amount shall commence increasing daily at the rate of 3.50% per annum
computed on a semi-annual bond equivalent yield basis. References in this
Indenture to the "principal amount" shall mean the Initial Principal Amount at
any time prior to September 30, 2010 and the principal amount as adjusted
upwards for accretion at any time on or after September 30, 2010 (the "Accreted
Principal Amount"); provided that references to the Accreted Principal Amount
shall mean the Initial Principal Amount prior to September 30, 2010.

          Section 3.11 Payment of Interest; Interest Rights Preserved. (a) Any
Interest (including Additional Interest) on any Security that is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date 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 clause (i) or (ii) below:

                                       42


          (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, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security, the date of the
proposed payment and the Special Record Date, 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 reasonably 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 as in this
clause provided. The Special Record Date for the payment of such Defaulted
Interest shall be not more than 15 days and not less than 10 days prior to the
date of the proposed payment and not less than 10 days after the receipt by the
Trustee of the notice of the proposed payment. The Trustee, 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 at such Holder's address as it
appears in the Security Register, not less than 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 at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause
(ii).

          (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, if, after notice given by the Company to the Trustee
of the proposed payment pursuant to this clause, such manner of payment shall be
deemed practicable by the Trustee.

          (b) Subject to the foregoing and following provisions of this Section
3.11 and Section 3.6, each Security delivered under this Indenture upon
registration of 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, which were
carried by such other Security.

          (c) Interest on any Security that is converted in accordance with
Section 12.1 during a Record Date Period shall be payable in accordance with the
provisions of Section 12.1.

          Section 3.12 Persons Deemed Owners. Prior to due presentment of a
Security for registration of transfer, the Company, the Trustee, any Paying
Agent and any agent of the Company, the Trustee or any Paying Agent may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of the principal amount of and
Interest on such Security (subject to Section 3.2 and Section 3.11) and for all
other purposes whatsoever, whether or not such Security be overdue, and neither
the Company, the Trustee, any Paying Agent nor any agent of the Company, the
Trustee or any Paying Agent shall be affected by notice to the contrary.

          Section 3.13 Cancellation. All Securities surrendered for payment,
redemption, repurchase, registration of transfer or exchange or conversion
shall, if surrendered to any Person

                                       43


other than the Trustee, be delivered to the Trustee. All Securities so delivered
to the Trustee shall be canceled promptly by the Trustee (or its agent). No
Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section. The Trustee shall dispose of all canceled
Securities in accordance with applicable law and its customary practices in
effect from time to time.

          Section 3.14 Computation of Interest. Interest on the Securities
(including any Additional Interest) shall be computed on the basis of a 360-day
year of twelve 30-day months. Notwithstanding any other provision of this
Indenture, the Company shall notify the Trustee in writing of the amount of any
Contingent Interest or Accreted Principal Amount with respect to the Securities,
and at the same time the Company shall deposit with the Trustee an amount of
money equal to any such amount proposed to be paid in respect of such Contingent
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the Interest Payment Date.

          Section 3.15 CUSIP Numbers. The Company in issuing Securities may use
"CUSIP" numbers (if then generally in use); if so, the Trustee shall use such
CUSIP numbers in notices of redemption and repurchase as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such CUSIP numbers either as printed on the Securities
or as contained in any notice of a redemption or repurchase and that reliance
may be placed only on the serial or other identification numbers printed on the
Securities, and any such redemption or repurchase shall not be affected by any
defect in or omission of such CUSIP numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

                                   ARTICLE IV

in the name, and at the expense, of the Company; and

          (iii) the Company has deposited or caused to be deposited with the
Trustee as trust funds (immediately available to the Holders in the case of

the Trustee under Section 4.2 and the last paragraph of Section 10.3 and the
obligations of the Company and the Trustee under Section 3.6 and Article XII

pursuant to Section 4.1 shall be held in trust for the sole benefit of the

Outstanding Securities;

          (viii) the entry by a court having jurisdiction in the premises of (A)
a decree or order for relief in respect of the Company or any Significant

of its inability to pay its debts generally as they become due, or the taking of
corporate action by the Company in furtherance of any such action;

          (b) If an Event of Default (other than an Event of Default arising
under Section 5.1(a)(viii) or (ix)) occurs and is continuing, then in every case
the Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities may declare the principal amount of plus accrued and

provided, if (i) all Events of Default with respect to the Securities have been
cured (other than the nonpayment of principal amounts or Interest that has
become due solely by reason of the declaration of acceleration) and (ii) a
rescission and annulment would not conflict with any judgment or decree issued
in appropriate judicial proceedings regarding the payment by the Trustee to the

will affect any subsequent default or impair any right consequent thereon.

          Section 5.2 Covenant of Company to Pay to Trustee Whole Amount Due on
Securities on Default in Payment of Interest or Principal; Suits for Enforcement
by Trustee. (a) The Company covenants that if (i) default is made in the payment
of any Interest on any Security when such Interest becomes due and payable and
such default continues for a period of 30 calendar days or (ii) default is made
in the payment of the principal amount of any Security when it becomes due and
payable, the Company will, upon demand of the Trustee, pay to it, for the
benefit of the Holders of such Securities and, to the extent that payment of
such interest will be legally enforceable, interest on any overdue principal
amount and, to the extent permitted by applicable law, on any overdue Interest,
at the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as will be sufficient to cover the reasonable costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel.

          (b) If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon the
Securities, wherever situated.

          (c) If an Event of Default with respect to any Security occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Securities by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

          (d) In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
will be entitled and empowered, by intervention in such proceeding or otherwise,
to take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee will be authorized to collect and receive any money or
other property payable or deliverable on any such claims and to distribute the
same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator,
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the
Trustee consents to the making of such payments directly to the Holders, to pay
to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel, and any
other amounts due the Trustee under Section 6.7.

          Section 5.3 Trustee May File Proof of Claim. (a) In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or the creditors of either,
the Trustee (irrespective of whether the principal of, and any Interest on, the
Securities shall then be

                                       48


due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or Interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

          (i) to file and prove a claim for the whole amount of the principal
amount and Interest owing and unpaid in respect of the Securities and take such
other actions, including participating as a member, voting or otherwise, of any
official committee of creditors appointed in such matter, and to file such other
papers or documents, in each of the foregoing cases, as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders of Securities allowed in
such judicial proceeding, and

          (ii) to collect and receive any moneys or other property payable or
deliverable on any such claim and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder of
Securities to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders of
Securities to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and any other amounts due the Trustee under Section 6.7.

          (b) Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder of a
Security any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder of a Security in any such
proceeding; provided, however, that the Trustee may, on behalf of such Holders,
vote for the election of a trustee in bankruptcy or similar official.

          Section 5.4 Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee will be brought in
its own name as trustee of an express trust, and any recovery of judgment will,
after provision for the payment of the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel, be for
the ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

          Section 5.5 Application of Money Collected. Any money collected by the
Trustee pursuant to this Article will be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of the principal amount or Interest, upon presentation of the
Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.7;

     SECOND: To the payment of the amounts then due and unpaid for principal of
and Interest (including Additional Interest) on the Securities in respect of
which or for the benefit of

                                       49


which such money has been collected, ratably, without preference or priority of
any kind, according to the amounts due and payable on such Securities for
principal amount and Interest, respectively; and

     THIRD: To such other Person or Persons, if any, to the extent entitled
thereto; and

     FOURTH: To the Company.

          Section 5.6 Limitation on Suits. No Holder of any Security shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

          (a) such Holder has previously given written notice to the Trustee of
a continuing Event of Default;

          (b) the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default, appoint a receiver or
pursue any other remedy hereunder, as applicable, in its own name as Trustee
hereunder;

          (c) such Holder or Holders have offered to the Trustee and, if
requested, shall have provided indemnity satisfactory to the Trustee against the
costs, expenses, and liabilities to be incurred in compliance with such request;

          (d) the Trustee for 60 calendar days after its receipt of such notice,
request and offer of indemnity (or if requested, receipt of indemnity) has
failed to institute any such proceeding; and

          (e) no direction inconsistent with such written request has been given
to the Trustee during the 60 calendar day period referred to in Section 5.6(d)
hereof by the Holders of a majority in aggregate principal amount of the
Outstanding Securities, it being understood and intended that no one or more of
such Holders will have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb, or prejudice
the rights of any other of such Holders, or to obtain or to seek to obtain
priority or preference over any other of such Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all of such Holders.

     The Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

     Notwithstanding the foregoing, this Section 5.6 shall not affect the right
of a Holder to sue for enforcement of the payment of the principal of or
Interest on its Security on or after the respective due dates in the Security or
the Holder's right to convert its Securities in accordance with the provisions
of this Indenture.

          Section 5.7 Notice of Defaults. If a default occurs hereunder with
respect to Securities, the Trustee will give the Holders notice of such Event of
Default of which it has actual notice within 90 calendar days of occurrence;
provided, however, to the extent consistent

                                       50


with the Trust Indenture Act, the Trustee may withhold notice of any Event of
Default (except a default of the character specified in Section 5.1(a)(i) or
Section 5.1(a)(ii) if the Trustee in good faith determines that the withholding
of such notice is in the interests of the Holders). The Company will give the
Trustee written notice of any default that could mature into an Event of Default
of the character described in Section 5.1(a)(vii) within 30 calendar days of
such default and of any uncured Event of Default within 10 days after any
Responsible Officer of the Company becomes aware of or receives actual notice of
such Event of Default.

          Section 5.8 Unconditional Right of Holders to Receive Principal and
Interest. Notwithstanding any other provision in this Indenture, the Holder of
any Security will have the right, which is absolute and unconditional, to
receive payment of the principal amount of and Interest on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption or repurchase, on the Redemption Date or Repurchase Date, as the case
may be) and, as contemplated by Article XII, to convert such Security in
accordance with its terms and to institute suit for the enforcement of any such
payment, and any such right to convert and such rights may not be impaired
without the consent of such Holder.

          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 to such Holder, then and in
every such case, subject to any determination in such proceeding, the Company,
the Trustee, and the Holders will be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders will continue as though no such proceeding had been
instituted.

          Section 5.10 Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost, or stolen Securities in the last paragraph of Section 3.7, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy will, 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, will 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 of any Holder of any Securities to exercise any right or remedy
accruing upon any Event of Default will 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 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 by the Holders, as the case may be.

          Section 5.12 Control by Holders of Securities. The Holders of a
majority in principal amount of the Outstanding Securities will 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, with respect to the Securities; provided that, the Trustee

                                       51


may refuse to follow any direction that conflicts with any rule of law or with
this Indenture, that is prejudicial to the rights of other Holders or that would
involve the Trustee in personal liability.

          Section 5.13 Waiver of Past Defaults. The Holders, either through the
written consent of not less than a majority in principal amount of the
Outstanding Securities or by the adoption of a resolution, at a meeting of
Holders of the Outstanding Securities at which a quorum is present, by the
Holders of at least a majority in aggregate principal amount of the Outstanding
Securities represented at such meeting, may, by notice to the Trustee, on behalf
of the Holders of all the Securities waive any past default hereunder and its
consequences, except a default (i) in the payment of the principal amount of or
Interest (including Additional Interest) on any Security, or (ii) in respect of
a covenant or provision hereof which under Article VIII cannot be modified or
amended without the consent of the Holder of each Outstanding Security affected.

     Upon any such waiver, such 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
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 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 any suit against
the Trustee for any action taken, suffered 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 shall
not apply to any suit instituted by the Company, to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder of any Security for the enforcement of
the payment of the principal amount of or Interest on any Security on or after
the respective Stated Maturity or Maturities expressed in such Security (or, in
the case of redemption or repurchase, on or after the Redemption Date or
Repurchase Date, as the case may be) or for the enforcement of the right to
convert any Security in accordance with Article XII.

          Section 5.15 Waiver of Stay, Usury 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 stay, usury or extension law wherever enacted, now
or at any time hereafter in force, that 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 by reason of such law 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 Certain Duties and Responsibilities. (a) 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, but in the case of
any such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture, but not to verify the contents thereof.

          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph (c) shall
not be construed to limit the effect of paragraph (a) of this Section; (ii) the
Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it shall be proved that the Trustee was negligent in
ascertaining the pertinent facts; (iii) 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 a majority in principal amount
of the Outstanding Securities relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture; and (iv) 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.

          (d) 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.

          (e) The Trustee may refuse to perform any duty or exercise any right
or power under this Indenture unless it receives indemnity satisfactory to it
against any loss, liability or expense.

          (f) If the Trustee becomes one of the Company's creditors, it may
become subject to limitations in the indenture on its rights to obtain payment
of claims or to realize on some property received for any such claim, as
security or otherwise. The Trustee is permitted to

                                       53


engage in other transactions with us. If, however, it acquires any conflicting
interest, it must eliminate that conflict or resign as Trustee under this
Indenture.

          Section 6.2 Notice of Defaults. Within 90 days after the occurrence of
any default hereunder as to which the Trustee has received written notice, the
Trustee shall give to all Holders of Securities, in the manner provided in
Section 1.6, notice of such default, unless such default shall have been cured
or waived; provided, however, that, except in the case of a default in the
payment of the principal amount of or Interest on any Security the Trustee shall
be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders.

          Section 6.3 Certain Rights of Trustee. Subject to the provisions of
Section 6.1:

          (a) the Trustee may conclusively rely, and shall be protected in
acting or refraining from acting, upon any resolution, Officers' Certificate,
other certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, coupon, other evidence of
indebtedness or other paper or document (collectively, the "Documents") believed
by it to be genuine and to have been signed or presented by the proper party or
parties, and the Trustee need not investigate any fact or matter stated in such
Documents;

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

          (c) 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 the one specifically prescribed) may, in the absence of bad faith on its
part, request and conclusively rely upon an Officers' Certificate or Opinion of
Counsel;

          (d) the Trustee may consult with counsel of its selection 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 of Securities pursuant to this Indenture, unless such Holders
shall have offered, and, if requested by the Trustee, delivered to the Trustee,
reasonable security against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;

          (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, debenture,
note, coupon, other evidence of indebtedness or other paper or document, but the
Trustee in its discretion may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to

                                       54


make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney
and shall, absent its bad faith, incur no liability of any kind by reason of
such inquiry or investigation;

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

          (h) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act
hereunder, absent bad faith on the part the of Trustee (in any such capacity)
and of such agent, custodian or other Person.

          Section 6.4 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 the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity, sufficiency or priority of this
Indenture, of the Securities or of the Common Stock issuable upon the conversion
of the Securities. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

          Section 6.5 May Hold Securities, Act as Trustee Under Other
Indentures. The Trustee, any Authenticating Agent, any Paying Agent, any
Conversion Agent or any other agent of the Company or the Trustee, 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, Conversion Agent or such
other agent.

     The Trustee may become and act as trustee under other indentures under
which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder.

          Section 6.6 Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. 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.

          Section 6.7 Compensation and Reimbursement. (a) The Company agrees:

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

          (ii) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by

                                       55


the Trustee (including costs and expenses of enforcing this Indenture and
defending itself against any claim (whether asserted by the Company, any Holder
of Securities or any other Person) or liability in connection with the exercise
of any of its powers or duties hereunder) 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 or bad faith; and

          (iii) to indemnify the Trustee (and its directors, officers, employees
and agents) for, and to hold it harmless against, any loss, liability or expense
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of this trust, including the
reasonable costs, expenses and reasonable attorneys' fees of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder.

          (b) The Trustee shall have a lien prior to the Securities on all money
or property held or controlled by the Trustee to secure the Company's payment
obligations in this Section, except that held in trust to pay principal and
Interest (including Additional Interest) on the Securities.

          (c) When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(a)(viii) or (ix), the expenses
(including the reasonable charges of its counsel) and the compensation for the
services are intended to constitute expenses of the administration under any
applicable Federal or state bankruptcy, insolvency or other similar law.

          (d) The provisions of this Section 6.7 shall survive the termination
of this Indenture or the earlier resignation or removal of the Trustee.

          Section 6.8 Corporate Trustee Required; Eligibility. There shall at
all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such, and the Trustee and its
parent corporation shall have (or be part of a holding company group with) a
combined capital and surplus of at least U.S. $50 million, subject to
supervision or examination by Federal or state authority, and in good standing.
The Trustee or an Affiliate of the Trustee shall maintain an established place
of business in the Borough of Manhattan, The City of New York. If such
corporation 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, 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, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article and a successor shall be appointed pursuant to Section 6.9.

          Section 6.9 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 shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 6.10.

                                       56


          (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 6.10 shall not have been delivered to the Trustee within 30
calendar 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.

          (c) The Trustee may be removed at any time by an Act of the Holders of
a majority in principal amount of the Outstanding Securities, delivered to the
Trustee and the Company. If the instrument of acceptance by a successor Trustee
required by Section 6.10 shall not have been delivered to the Trustee within 30
calendar days after the giving of such notice of removal, the removed Trustee
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

          (d) The Trustee may be removed at any time by the Company and the
Company may appoint a successor Trustee pursuant to this Article; provided that,
(i) there is not an Event of Default that is continuing at the time of removal,
(ii) the successor Trustee appointed by the Company meets the eligibility
requirements of Section 6.8, and (iii) such removal and resignation shall not
become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 6.10.

          (e) If at any time: (i) the Trustee shall cease to be eligible under
Section 6.8 and shall fail to resign after written request therefor by the
Company or by any Holder of a Security who has been a bona fide Holder of a
Security for at least six months, or (ii) the Trustee shall become incapable of
acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee
or of its property shall be appointed or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then, in any such case (i) the
Company by a Board Resolution may remove the Trustee, or (ii) subject to Section
5.14, any Holder of a Security who has been a bona fide Holder of a Security for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          (f) 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 cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee and
shall comply with the applicable requirements of this Section 6.9 and Section
6.10. If no successor Trustee shall have been so appointed by the Company or the
Holders of Securities and accepted appointment in the manner required by this
Section 6.9 and Section 6.10, any Holder of a Security who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

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

                                       57


          Section 6.10 Acceptance of Appointment by Successor. Every successor
Trustee appointed hereunder 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. 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 such rights, powers and trusts.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be eligible under this Article.

          Section 6.11 Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee (including the trust created by this Indenture), by sale
or otherwise, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and
deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

          Section 6.12 Authenticating Agents. (a) The Trustee may, with the
consent of the Company, appoint an Authenticating Agent or Agents acceptable to
the Company with respect to the Securities, which Authenticating Agent shall be
authorized to act on behalf of the Trustee to authenticate Securities issued
upon exchange or substitution pursuant to this Indenture.

          (b) Securities authenticated by an Authenticating Agent 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, and every reference
in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
subject to acceptance by the Company and shall at all times be a corporation
organized and doing business under the laws of the United States of America, any
State thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent and subject to supervision or examination by government or
other fiscal authority. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of

                                       58


this Section 6.12, such Authenticating Agent shall resign immediately in the
manner and with the effect specified in this Section 6.12.

          (c) Any corporation into which an Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 6.12, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

          (d) 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, the Trustee may appoint a successor Authenticating
Agent which shall be subject to acceptance by the Company. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

          (e) The Company agrees to pay to each Authenticating Agent from time
to time reasonable compensation for its services under this Section.

          (f) If an Authenticating Agent is appointed with respect to the
Securities pursuant to this Section, the Securities may have endorsed thereon,
in addition to or in lieu of the Trustee's certification of authentication, an
alternative certificate of authentication in the following form:

     This is one of the Securities referred to in the within-mentioned
Indenture.

          Section 6.13 Disqualification; Conflicting Interests. If the Trustee
has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to
the extent and in the manner provided by, and subject to the provisions of, the
Trust Indenture Act and this Indenture.

          Section 6.14 Preferential Collection of Claims Against Company. If and
when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Company
(or any such other obligor).

                                  ARTICLE VII
                     CONSOLIDATION, MERGER, SALE OR TRANSFER

          Section 7.1 Company May Consolidate, Etc. Only on Certain Terms.

          (a) The Company shall not (i) consolidate with or merge with or into
any other Person, or convey, sell, transfer or lease or otherwise dispose of all
or substantially all of its assets to any other Person in any one transaction or
a series of related transactions; or (ii) permit any Person to consolidate with
or merge with or into the Company, unless:

          (i) in the case of a merger or consolidation, either the Company is
the surviving Person or, if the Company is not the surviving Person, the
surviving Person formed by such merger or consolidation or into which the
Company is merged or consolidated or in the case of a conveyance, sale,
transfer, lease or other disposition of all or substantially all of the
Company's assets, the Person to which the Company's properties and assets are so
transferred shall be a corporation organized and existing under the laws of the
United States, any state thereof, or the District of Columbia, and shall execute
and deliver to the Trustee a supplemental indenture expressly assuming the
payment when due of the principal amount of and Interest, if any, on the
Securities and the performance of each of the Company's other covenants under
the Securities and this Indenture;

          (ii) in either case, immediately after giving effect to such
transaction, no default or Event of Default shall have occurred and be
continuing; and

          (iii) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such merger,
consolidation, conveyance, transfer or lease and, if a supplemental indenture is
required, such supplemental indenture comply with this Article VII and that all
conditions precedent provided for in this Indenture relating to such transaction
have been complied with.

          (b) In the case of a merger or consolidation pursuant to which all or
substantially all of the Common Stock would be converted into cash, securities
or other property, or any sale, transfer or lease of all or substantially all of
the Company's assets, the right to convert a Security into Common Stock will be
changed into a right to convert such Security into the type and amount of cash,
securities or other property that the Holder of such Security would have
received had the Holder held a number of shares of Common Stock equal to the
product of

                                       60


37.5090 and the Parity Share Number then in effect immediately prior to the
transaction; provided, however, that upon conversion such Holder will continue
to receive cash in satisfaction of all or a portion of the Conversion
Consideration as provided in Article XII. In such event, the Company and the
Trustee shall enter into a supplemental indenture providing for adjustments
that, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article VII. The above provisions of this
Section shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers, leases or other dispositions. Notice of the
execution of such a supplemental indenture shall be given by the Company to the
Holder of each Security as provided in Section 1.6 promptly upon such execution.
For purposes of this Section 7.1(b), the type and amount of consideration that a
Holder would have been entitled to receive as a holder of the Common Stock in
the case of a merger or consolidation that causes the Common Stock to be
converted into the right to receive more than a single type and amount of
consideration (determined based in part upon any form of stockholder election),
will be deemed to be the weighted average of the types and amounts of
consideration received by the holders of the Common Stock that affirmatively
make such an election. In addition, if the transaction constitutes a Change in
Control and a Holder converts such Holder's Securities in connection with a
Change in Control, the Capped Anti-Dilution Multiplier will be increased (but
only prior to September 30, 2010), as provided in Section 12.10.

          (c) Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
Common Stock or other securities or property or cash receivable by Holders of
Securities upon the conversion of their Securities after any such consolidation,
merger, conveyance, transfer, sale, lease (or other disposition or to any such
adjustment, but may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, an Officers' Certificate or
an Opinion of Counsel with respect thereto, which the Company shall cause to be
furnished to the Trustee.

          Section 7.2 Successor Substituted. Upon any consolidation of the
Company with, or merger of the Company into, any other Person or any sale,
transfer or lease, sale or other disposition of all or substantially all the
properties and assets of the Company in accordance with Section 7.1, the
successor Person formed by such consolidation or into which the Company is
merged or to which such sale, transfer, lease or other disposition is made shall
succeed to and be substituted for, and may exercise every right and power of the
Company under this Indenture with the same effect as if such successor or Person
had been named as the Company herein, and thereafter, except in the case of a
lease, the predecessor Person shall be relieved of all obligations and covenants

the Trustee of the documents described in Section 8.3 hereof, the Trustee shall

                                       62


execution of any supplemental indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations
that may be therein contained.

     Notwithstanding any other provision of this Indenture or the Securities,
the Registration Rights Agreement and the obligation to pay Additional Interest
thereunder may only be amended, modified or waived in accordance with the
provisions of the Registration Rights Agreement.

          Section 8.2 Supplemental Indentures with Consent of Holders of

the Securities.

     It shall not be necessary for any Act of Holders of Securities under this
Section 8.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

          Section 8.3 Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Sections
6.1 and 6.3) shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of such supplemental indenture is authorized or
permitted by this Indenture, and that such supplemental indenture has been duly
authorized, executed and delivered by the Company, constitutes a valid and
legally binding obligation of the Company enforceable against the Company in
accordance with its terms and does not conflict with or violate the terms of
this Indenture. The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which adversely affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

          Section 8.4 Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article VIII, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder appertaining
thereto shall be bound thereby.

          Section 8.5 Reference in Securities to Supplemental Indentures.
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Securities
so modified as to conform, in the opinion of the Company and the Trustee, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities.

          Section 8.6 Notice of Supplemental Indentures. Promptly after the
execution by the Company and the Trustee of any supplemental indenture pursuant
to the provisions of Section 8.1 or Section 8.2, the Company shall give notice
to all Holders of Securities of such fact, setting forth in general terms the
substance of such supplemental indenture, in the manner provided in Section 1.6.
Any failure of the Company to give such notice, or any defect therein, shall not
in any way impair or affect the validity of any such supplemental indenture.

any time call a meeting of Holders of Securities for any purpose specified in
Section 9.1, to be held at such time and at such place in the Borough of
Manhattan, The City of New York, as the Trustee shall determine. Notice of every
meeting of Holders of Securities, setting forth the time and the place of such
meeting and in general terms the action proposed to be taken at such meeting,

reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 21 days after
receipt of such request or shall not thereafter proceed to cause the meeting to
be held as provided herein, then the Company or the Holders of Securities in the
amount specified, as the case may be, may determine the time and the place in

reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage of the principal amount of the Outstanding Securities

different vote) shall be effectively passed and decided if passed or decided by
the lesser of: (i) the Holders of not less than a majority in aggregate
principal amount of Outstanding Securities and (ii) the Persons entitled to vote

the Holders of Securities whether or not present or represented at the meeting.
The Trustee shall, in the name and at the expense of the Company, notify all the
Holders of Securities of any such resolutions or decisions pursuant to Section
1.6.

          Section 9.5 Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any

and of the appointment of proxies and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the

temporary chairman (which may be the Trustee) of the meeting, unless the meeting
shall have been called by the Company or by Holders of Securities as provided in
Section 9.2(b), in which case the Company or the Holders of Securities calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities represented at the meeting.

                                       66


          (c) At any meeting, each Holder of a Security or proxy shall be
entitled to one vote for each U.S. $1,000 principal amount of Securities held or
represented by him; provided, however, that no vote shall be cast or counted at
any meeting in respect of any Security challenged as not Outstanding and ruled
by the chairman of the meeting to be not Outstanding. The chairman of the
meeting shall have no right to vote, except as a Holder or proxy.

          (d) Any meeting of Holders of Securities duly called pursuant to
Section 9.2 at which a quorum is present may be adjourned from time to time by
Persons entitled to vote a majority in principal amount of the Outstanding
Securities represented at the meeting, and the meeting may be held as so
adjourned without further notice.

          Section 9.6 Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities shall be
by written ballots on which shall be subscribed the signatures of the Holders of
Securities or of their representatives by proxy and the principal amounts at
Stated Maturity and serial numbers of the Outstanding Securities held or
represented by them. The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A
record, at least in duplicate, of the proceedings of each meeting of Holders of
Securities shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more Persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 9.2(a) and, if
applicable, Section 9.4(a). Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                                   COVENANTS

          Section 10.1 Payment of Principal and Interest. The Company covenants
and agrees that it will duly and punctually pay the principal amount of and
Interest on the Securities in accordance with the terms of the Securities and
this Indenture. The Company will deposit or cause to be deposited with the

due date for any installment of Interest, all payments so due, which payments
shall be in immediately available funds on the date of such Stated Maturity or
due date, as the case may be.

          Section 10.2 Maintenance of Offices or Agencies. The Company will
maintain in the Borough of Manhattan, The City of New York, an office or agency

and this Indenture may be served. The Company will give prompt

                                       67


written notice to the Trustee of the location, and any change in the location,
of such office or agency not designated or appointed by the Trustee. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office or the office or agency of the Trustee in the Borough of Manhattan, The
City of New York.

     The Company may at any time and from time to time vary or terminate the
appointment of any such agent or appoint any additional agents for any or all of
such purposes; provided, however, that until all of the Securities have been
delivered to the Trustee for cancellation, or moneys sufficient to pay the
principal amount of and Interest on the Securities have been made available for
payment and either paid or returned to the Company pursuant to the provisions of
Section 10.3, the Company will maintain in the Borough of Manhattan, The City of
New York, an office or agency where Securities may be presented or surrendered
for payment and conversion, which shall initially be the Corporate Trust Office
of the Trustee, where Securities may be surrendered for registration of transfer
or exchange and where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served. The Company will give prompt
written notice to the Trustee, and notice to the Holders in accordance with
Section 1.6, of the appointment or termination of any such agents and of the
location and any change in the location of any such office or agency.

     The Company hereby initially designates the Trustee as Paying Agent,
Security Registrar and Conversion Agent, and the Corporate Trust Office of the
Trustee as one such office or agency of the Company for each of the aforesaid
purposes.

          Section 10.3 Money for Security Payments to Be Held in Trust. (a) If
the Company shall act as its own Paying Agent, it will, on or before each due
date of the principal amount of or Interest on any of the Securities, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal amount of or Interest so becoming due until such
sums shall be paid to such Persons or otherwise disposed of as herein provided
and the Company will promptly notify the Trustee, in writing, of its action or
failure so to act.

          (b) Whenever the Company shall have one or more Paying Agents, it
will, no later than the opening of business on each due date of the principal
amount or Interest on any Securities, deposit with the Trustee a sum in funds
immediately payable on the payment date sufficient to pay the principal amount
or Interest so becoming due, such sum to be held for the benefit of the Persons
entitled to such principal amount or Interest and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee, in writing, of any
failure so to act.

          (c) The Company will cause each Paying Agent 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 that
such Paying Agent will:

          (i) hold all sums held by it for the payment of the principal amount
of or Interest on Securities for the benefit of the Persons entitled thereto
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided;

                                       68


          (ii) give the Trustee written notice of any default by the Company (or
any other obligor upon the Securities) in the making of any payment of principal
amount or Interest; and

          (iii) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held by
such Paying Agent.

          (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 amount of or
Interest on any Security and remaining unclaimed for two years after such
principal amount or Interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall 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.

          (f) In the absence of a written request from the Company to return
unclaimed funds to the Company, the Trustee shall from time to time deliver all
unclaimed funds to or as directed by applicable escheat authorities, as
determined by the Trustee in its sole discretion, in accordance with the
customary practices and procedures of the Trustee. Any unclaimed funds held by
the Trustee pursuant to this Section shall be held uninvested and without any
liability of interest.

          Section 10.4 Existence. Subject to Article VII, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights (charter and statutory) and franchises; provided,
however, that the Company shall not be required to preserve any such right or
franchise if the Company shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

          Section 10.5 Maintenance of Properties. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Subsidiary to be maintained and kept in good condition, repair and working order
and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section shall prevent the
Company from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, in

                                       69


the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

          Section 10.6 Payment of Taxes and Other Claims. The Company will pay
or discharge, or cause to be paid or discharged, before the same may become
delinquent,

upon the Company or any Subsidiary or upon the income, profits or property of
the Company or any Significant Subsidiary,

          (b) all claims for labor, materials and supplies which, if unpaid,
might by law become a lien or charge upon the property of the Company or any
Significant Subsidiary, and

          (c) subject to Section 12.14, all stamps and other duties, if any,
which may be imposed by the United States or any political subdivision thereof
or therein in connection with the issuance, transfer, exchange or conversion of
any Securities or with respect to this Indenture;

provided, however, that, in the case of clauses (a) and (b), the Company shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim (i) if the failure to do so will not, in the
aggregate, have a material adverse impact on the Company and its Subsidiaries
taken as a whole, or (ii) if the amount, applicability or validity is being
contested in good faith by appropriate proceedings.

          Section 10.7 Registration and Listing. The Company will effect all
registrations with, and obtain all approvals by, all governmental authorities
that may be necessary under any United States federal or state law (including
the Securities Act, the Exchange Act and state securities and Blue Sky laws)
before the shares of Common Stock issuable upon conversion of Securities are
issued and delivered, and qualified or listed as contemplated under the
Registration Rights Agreement.

     Nothing in this Section will limit the application of Section 10.12.

          Section 10.8 Statement by Officers as to Default. (a) The Company
shall deliver to the Trustee, within 90 days after the end of each fiscal year
of the Company ending after the date hereof, an Officers' Certificate, stating
whether or not to the best knowledge of the signer thereof the Company is in
default in the performance and 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.

          (b) The Company will deliver to the Trustee, forthwith upon becoming
aware of any default or any Event of Default under the Indenture, an Officers'
Certificate specifying with particularity such default or Event of Default and
further stating what action the Company has taken, is taking or proposes to take
with respect thereto.

          (c) Any notice required to be given under this Section shall be

          Section 10.9 Delivery of Certain Information. At any time when the
Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the
request of a Holder of a Restricted Security or the holder of shares of Common
Stock issued upon conversion thereof, the Company will promptly furnish or cause
to be furnished Rule 144A Information to such Holder of Restricted Securities or
such holder of shares of Common Stock issued upon conversion of Restricted
Securities, or to a prospective purchaser of any such security designated by any
such Holder or holder, as the case may be, to the extent required to permit
compliance by such Holder or holder with Rule 144A under the Securities Act (or
any successor provision thereto) in connection with the resale of any such
security; provided, however, that the Company shall not be required to furnish
such information in connection with any request made on or after the date that

last acquired from the Company or

          (b) the date such a Security (or any such predecessor security) was
last acquired from an "affiliate" of the Company within the meaning of Rule 144
under the Securities Act (or any successor provision thereto). "Rule 144A
Information" shall be such information as is specified pursuant to Rule
144A(d)(4) under the Securities Act (or any successor provision thereto).

          Section 10.10 Tax Treatment of Securities. The Company agrees, and by
acceptance of a beneficial ownership interest in the Securities each Holder of
Securities has agreed, for United States federal income tax purposes,

          (a) (i) to treat the Securities as contingent payment debt instruments
as defined in Treasury Regulation Section 1.1275-4 (the "Contingent Payment
Regulations") and, for purposes of the Contingent Payment Debt Regulations, to
treat the Fair Market Value of any Common Stock beneficially received by a
beneficial owner upon conversion of the Securities as a contingent payment; and
(ii) to accrue interest with respect to the Securities as original issue
discount on a constant yield basis using the comparable yield of 7.375% per
annum compounded semi-annually;

          (b) to be bound by the Company's application of the Contingent Payment
Debt Regulations to the Securities including the Company's determination of the
comparable yield and projected payment schedule, within the meaning of the
Contingent Payment Debt Regulations, with respect to the Securities. A Holder of
Securities may obtain the Issue Price, Issue Date, comparable yield and
projected payment schedule by submitting a written request to the Company at the
following address: Conseco, Inc., 11825 N. Pennsylvania Street, Carmel, Indiana
46032, Attention: Investor Relations;

          (c) that the comparable yield and the projected payment schedule are
determined on the basis of an assumption of a fixed growth of stock price and
the comparable yield and the projected payment schedule are not determined for
any purpose other than for the purpose of applying Treasury Regulation section
1.1275-4(b)(4) to the Security, and the comparable yield and the projected
payment schedule do not constitute a projection or representation regarding the
actual amounts payable on the Securities;

                                       71


          (d) that each Holder shall use the projected payment schedule with
respect to the Securities described in Section 10.10(b) above, as required by
Treasury Regulations Section 1.1275-4(b)(4)(iv), to determine its interest
accruals and adjustments as provided in Treasury Regulation Section 1.1275-4(b);
and

          (e) not to take any position on a tax return inconsistent with (a),
(b), (c) or (d), unless otherwise required by applicable law.

          Section 10.11 Resale of Certain Securities. During the period
beginning on the last date of original issuance of the Securities and ending on
the date that is two years from such date (or such shortened period under Rule
144(k) under the Securities Act or any successor rule), the Company will not,
and will not permit any of its subsidiaries or other "affiliates" (as defined
under Rule 144 under the Securities Act or any successor provision thereto) to,
resell:

          (a) any Securities that constitute "restricted securities" under Rule
144 or

          (b) any securities into which the Securities have been converted under
this Indenture that constitute "restricted securities" under Rule 144 that in
either case have been reacquired by any of them.

     The Trustee shall have no responsibility in respect of the Company's
performance of its agreement in the preceding sentence.

          Section 10.12 Registration Rights. (a) The Company agrees that the
Holders from time to time of Registrable Securities are entitled to the benefits
of the Registration Rights Agreement.

          (b) Whenever in this Indenture there is mentioned, in any context, the
payment of the principal amount of or Interest on, or in respect of, any
Security, such mention shall be deemed to include mention of the payment of
Additional Interest provided for in this Section and the Registration Rights
Agreement to the extent that, in such context, Additional Interest is, was or
would be payable in respect thereof pursuant to the provisions of this Section
and the Registration Rights Agreement and express mention of the payment of
Additional Interest (if applicable) in any provisions hereof shall not be
construed as excluding Additional Interest in those provisions hereof where such
express mention is not made.

          (c) If a Security, or the shares of Common Stock issuable upon
conversion of a Security, is a Registrable Security, and the Holder thereof
elects to sell such Registrable Security pursuant to the Shelf Registration
Statement then, by its acceptance thereof, the Holder of such Registrable
Security will have agreed to be bound by the terms of the Registration Rights
Agreement relating to the Registrable Securities which are the subject of such
election.

          (d) For the purposes of the Registration Rights Agreement, the term
"Holder" means any Person that is the record owner of Registrable Securities
(and includes any Person that has a beneficial interest in any Registrable
Security in book entry form).

          (e) If Additional Interest is payable under the Registration Rights
Agreement, the Company shall deliver to the Trustee a certificate to that effect
stating:

                                       72


          (i) the amount of Additional Interest that is payable and

          (ii) the date on which Additional Interest is payable.

          (f) Unless and until a Responsible Officer of the Trustee receives at
the Corporate Trust Office such a certificate, the Trustee may assume without
inquiry that no Additional Interest is payable. If Additional Interest has been
paid by the Company directly to the Persons entitled to them, the Company shall
deliver to the Trustee a certificate setting forth the particulars of such
payment.

          Section 10.13 Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 10.4 (other than with respect to the existence of the Company (subject
to Article VII)), 10.5 and 10.6, inclusive (other than a covenant or condition
which under Article VII cannot be modified or amended without the consent of the
Holder of each Outstanding Security affected), if before the time for such
compliance the Holders shall, through:

          (a) the written consent of not less than a majority in aggregate
principal amount of the Outstanding Securities or

          (b) the adoption of a resolution at a meeting of Holders of the
Outstanding Securities at which a quorum is present by the Holders of not less
than a majority in aggregate principal amount of the Outstanding Securities
represented at such meeting,

either waive such compliance in such instance or generally waive compliance with
such covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee or any Paying or Conversion Agent in respect of any such covenant or
condition shall remain in full force and effect.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

          Section 11.1 Right of Redemption. The Company will have the right to
redeem the Securities, in whole or in part, for cash at any time or from time to
time on or after October 5, 2010 at a Redemption Price equal to 100% of the
Accreted Principal Amount of the Securities selected for redemption, plus
accrued and unpaid Interest, if any, to, but not including, the Redemption Date.

          Section 11.2 Applicability of Article. Redemption of Securities at the
election of the Company or otherwise, as permitted or required by any provision
of the Securities or this Indenture, shall be made in accordance with such
provision and this Article XI.

          Section 11.3 Election to Redeem; Notice to Trustee. (a) The election
of the Company to redeem any Securities will be evidenced by a Board Resolution.
In case of any redemption, the Company will, at least 60 calendar days prior to
the Redemption Date fixed by

                                       73


the Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee in writing of such Redemption Date and of the Accreted
Principal Amount of Securities of such series to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company will furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

          (b) If less than all the Securities are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 calendar days prior
to the Redemption Date by the Trustee, from the Outstanding Securities not
previously called for redemption, on a pro rata basis unless another method is
required by the New York Stock Exchange or The Nasdaq National Market or another
national or regional securities exchange on which the Common Stock is then
listed or quoted. If any Security selected for partial redemption is converted
in part before termination of the conversion right with respect to the portion
of the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption by the
Trustee in accordance with the preceding sentence. Securities which have been
converted during a selection of Securities to be redeemed may be treated by the
Trustee as Outstanding for the purpose of such selection. The Trustee shall
promptly notify the Company and each Security Registrar in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the Accreted Principal Amount thereof to be redeemed.

          (c) For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

          Section 11.4 Notice of Redemption. Notice of redemption of Securities
to be redeemed will be given by the Company or, at the Company's written request
(which request shall be delivered to the Trustee simultaneously with
notification of the Redemption Date pursuant to Section 11.3), by the Trustee in
the name and at the expense of the Company and will be irrevocable (such notice,
a "Redemption Notice"). A Redemption Notice will be given by mail, first class
postage prepaid, not less than 30 or more than 60 calendar days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at his address
appearing in the Security Register. All notices of redemption will include the
CUSIP number and will state:

          (i) the Redemption Date;

          (ii) the Redemption Price and accrued Interest;

          (iii) if less than all the Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption of any
Securities, the Accreted Principal Amounts) of the particular Securities to be
redeemed;

          (iv) that on the Redemption Date the Redemption Price will become due
and payable upon each such Security to be redeemed and, if applicable, that
Interest thereon will cease to accrue on and after said date;

                                       74


          (v) that Securities called for redemption may be converted at any time
prior to the close of business on the Business day immediately preceding the
Redemption Date;

          (vi) the place or places where such Securities are to be surrendered
for payment of the Redemption Price; and

          (vii) the specific provision of this Indenture pursuant to which such
Securities are to be redeemed.

     Notice of redemption of Securities to be redeemed shall be given by the
Trustee to each Paying Agent in the name of and at the expense of the Company.

     If the Company exercises its right to redeem the Securities, in whole or in
part, it will disseminate a Press Release containing information regarding the
redemption and publish the information through a public medium that is customary
for such Press Release.

          Section 11.5 Deposit of Redemption Price. Prior to 10:00 a.m. (local
time at the Place of Payment) on the Redemption Date specified in the Redemption
Notice given as provided in Section 11.4, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of
money (which shall be in immediate available funds on such Redemption Date)
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) any accrued Interest to, but not including,
the Redemption Date on, all of the Securities that are to be redeemed on that
date other than any Securities called for redemption on the date which have been
converted prior to the date of such deposit.

     If any Security called for redemption is converted, any money deposited
with the Trustee or so segregated and held in trust for the redemption of such
Security shall (subject to any right of the Holder of such Security or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 3.11) be paid to the Company or, if then held by the Company, shall be
discharged from such trust.

          Section 11.6 Securities Payable on Redemption Date. (a) A Redemption
Notice having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein
specified, and from and after such date (unless the Company shall default in the
payment of the Redemption Price, including accrued Interest) such Securities
shall cease to accrue Interest. Upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued and unpaid Interest to,
but not including, the Redemption Date.

          (b) If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the Accreted Principal Amount and, to the
extent permitted by applicable law, accrued Interest shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security and such Security shall remain convertible until the Redemption Price
of such Security (or portion thereof, as the case may be) has been paid in full.

                                       75


          Section 11.7 Securities Redeemed in Part. (a) Any Security that is to
be redeemed only in part shall be surrendered at a Place of Payment therefor
(with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Security without service charge, a new Security or
Securities of like tenor, of any authorized denomination as requested by such
Holder, in aggregate Accreted Principal Amount equal to and in exchange for the
unredeemed portion of the Accreted Principal Amount of the Security so
surrendered.

          (b) In the event of any redemption in part, the Company and the
Trustee will not be required

          (i) to issue, register the transfer of, or exchange any Securities
during a period beginning at the opening of business 15 calendar days before the
mailing of a Redemption Notice of Securities selected for redemption under
Section 11.3 and ending at the close of business on the day of such mailing 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 Securities to be
redeemed in part, the portion thereof not being redeemed.

                                  ARTICLE XII
                            CONVERSION OF SECURITIES

          Section 12.1 Right to Convert. Subject to and upon compliance with the
provisions of this Article XII, at the option of the Holder, any Securities or
any portion of the principal amount thereof that is an integral multiple of
$1,000 (but for purposes of such denominations based on the Initial Principal
Amount of such Securities) may be converted:

          (a) prior to September 30, 2034, during any Conversion Period, if the
Parity Price of the Common Stock for at least 20 Trading Days in the 30
consecutive Trading Day period ending on the first day of that Conversion Period
is greater than 120% of the product of (i) $26.66 and (ii) the Accreted
Principal Amount of a Security with an Initial Principal Amount of $1,000
divided by $1,000;

          (b) prior to September 30, 2034, during the five consecutive Business
Day period following any five consecutive Trading Day period in which the
Trading Price of a Security with an Initial Principal Amount of $1,000 for each
day of that five Trading Day period was less than 98% of the of the product of
(i) the Parity Price and (ii) 37.5090;

          (c) at any time on or after September 30, 2034;

          (d) if the Securities are called for redemption pursuant to Article
XI, at any time after the date of the mailing of the applicable Redemption
Notice and prior to the close of business on the Business Day immediately
preceding the Redemption Date; provided that if the

                                       76


Company elects to redeem less than all of the Securities, only those Securities
called for redemption may be converted; or

          (e) upon the occurrence of a corporate transaction described in
Section 12.2.

     Notwithstanding the provisions of this Section 12.1, prior to September 30,
2010, except in the case of a conversion of Securities made in connection with a
Fundamental Change (as provided in Section 12.5), Holders will not have the
option to convert Securities if such conversion would result in a default under
the terms of the Company's other outstanding Indebtedness or would otherwise be
prohibited by the terms of such other Indebtedness.

          Section 12.2 Certain Corporate Transactions.

          (a) If the Company elects to:

          (i) distribute to all holders of Common Stock rights, options or
warrants entitling them to purchase, for a period expiring within 60 days of the
declaration date for such distribution, shares of Common Stock at less than the
Closing Price of the Common Stock on the Trading Day immediately preceding the
declaration date for such distribution; or

          (ii) distribute to all holders of Common Stock assets, debt securities
or rights, options or warrants to purchase securities of the Company, which
distribution has a per share fair market value (determined in the manner
specified in Section 12.9(f)) exceeding 10% of the Closing Price of the Common
Stock on the Trading Day immediately preceding the declaration date for such
distribution;

then in the case of the foregoing clauses (i) and (ii), the Company shall notify
the Holders at least 20 days prior to the ex-dividend date for such
distribution. Once the Company has given such notice, even if the Securities are
not otherwise convertible at such time, Holders may surrender their Securities
for conversion at any time thereafter until the earlier of the close of business
on the Business Day immediately prior to the ex-dividend date or the Company's
announcement that such distribution will not take place, subject to the
limitations imposed by the last paragraph of Section 12.1; provided, however,
that a Holder may not exercise this right to convert if the Holder is otherwise
entitled to participate in the distribution without conversion. As used herein,
the term "ex-dividend date" or "ex-date" when used with respect to any issuance
or distribution, shall mean the first date upon which a sale of shares of Common
Stock does not automatically transfer the right to receive the relevant dividend
or distribution from the seller of such Common Stock to its buyer.

          (b) If the Company is party to a consolidation, merger or binding
share exchange pursuant to which all or substantially all of the Common Stock
would be converted into cash, securities or other property, even if the
Securities are not otherwise convertible at the time, Holders may surrender
their Securities for conversion at any time from and after the date that is 15
days prior to the anticipated effective date of the transaction until 15 days
after the actual date of the transaction. If such consolidation, merger or
binding share exchange constitutes a Fundamental Change, the right to convert
Securities contemplated by this Section 12.2(b) will not be subject to the
limitations imposed by the last paragraph of Section 12.1.

                                       77


          (c) If a Fundamental Change occurs, Holders may surrender their
Securities for conversion during the period described in paragraph (b) above.
However, a conversion of a Security will only be considered "in connection with"
a Fundamental Change if the Security is surrendered during the period described
in Section 12.5(e) and the provisions of Section 12.5(d) and Section 12.5(e) are
complied with. Section 12.10 provides for an adjustment to the Capped
Anti-Dilution Multiplier only if a Security is deemed to be converted "in
connection with" a Change in Control.

          Section 12.3 Determination of Satisfaction of Certain Conversion
Triggers. (a) Prior to September 30, 2034, the Company shall determine if the
Securities are convertible in accordance with Section 12.1(a) and shall notify
the Trustee if the Securities become convertible. The Company or its Agent shall
make such determination during the 30 consecutive Trading Days ending on the
first day of each Conversion Period.

          (b) The Company shall determine if the Securities are convertible in
accordance with Section 12.1(b) and notify the Trustee if the Securities become
convertible; provided that, the Company shall have no obligation to make such
determination unless requested in writing to do so by a Holder. Upon such
request, the Company shall determine the Trading Price of a Security with an
Initial Principal Amount of $1,000 beginning on the next Trading Day and on each
successive Trading Day until the Trading Price of a Security with an Initial
Principal Amount of $1,000 is greater than or equal to 98% of the product of (1)
the Parity Price and (2) 37.5090. For this purpose, if the Company cannot
reasonably obtain at least one bid for $5.0 million in Initial Principal Amount
of the Securities from a nationally recognized securities dealer or if, in the
reasonable judgment of the Company, the bid quotations are not indicative of the
secondary market value of the Securities, then a Holder may surrender Securities
for conversion during the five consecutive Business Day period following such
event or determination.

          Section 12.4 Notice of Conversion. Upon the determination by or on
behalf of the Company that Holders are or will be entitled to convert the
Securities in accordance with the provisions of Section 12.1 or Section 12.2,
the Company will issue a Press Release containing information about the right of
conversion, publish the information through a public medium that is customary
for such Press Release and publish the information on the Company's website.

          Section 12.5 Conversion at Option of the Holder Upon a Fundamental
Change.

          (a) If a Fundamental Change occurs at any time prior to Maturity, each
Holder will have the right to convert any or all of such Holder's Securities
into Conversion Consideration pursuant to the procedures set forth in this
Section 12.5.

          (b) On or before the fifth day after the occurrence of a Fundamental
Change, the Company will provide to all Holders, the Trustee and the Paying
Agent a notice of the occurrence of the Fundamental Change (such notice, a
"Fundamental Change Notice") and of the resulting rights of Holders. Each
Fundamental Change Notice shall state, among other things:

          (i) the events causing the Fundamental Change;

                                       78


          (ii) the date of the Fundamental Change;

          (iii) the last date (determined as provided below) on which a Holder
may exercise its conversion right in connection with such Fundamental Change;

          (iv) the Fundamental Change Election Date, which date shall be no less
than 22 days after the date of the applicable Fundamental Change Notice (but not
more than 35 days, unless a longer period is required by law);

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

          (vi) the Parity Price, the Parity Share Number and any adjustments to
the Parity Share Number (including any adjustments to the Capped Anti-Dilution
Multiplier pursuant to Section 12.10 hereof);

          (vii) the Conversion Consideration (or, if not known, the method for
determining the amount of Conversion Consideration) that Holders will be
entitled to receive upon conversion; and

          (viii) the procedures that Holders must follow to convert their
Securities.

          (c) Simultaneously with providing the Fundamental Change Notice, the
Company will issue a Press Release and publish the information contained therein
through a public medium customary for such Press Releases.

          (d) To exercise the conversion right contemplated by this Section
12.5, a Holder must deliver, before the close of business on the second Business
Day immediately preceding the Fundamental Change Election Date, the Fundamental
Change Election Notice, duly completed, to the Paying Agent. The Fundamental
Change Election Notice must state:

          (i) if certificated, the certificate numbers of the Securities to be
delivered for conversion;

          (ii) the portion of the Initial Principal Amount of the Securities to
be converted, which must be $1,000 or an integral multiple thereof; and

          (iii) that the Securities are to be converted by the Company pursuant
to the applicable provisions of the Securities and this Indenture.

     If the Securities are Global Securities, the Fundamental Change Election
Notice must comply with the Applicable Procedures.

          (e) A conversion of Securities by a Holder will be deemed for purposes
of this Section 12.5 and Section 12.10 to be "in connection with" a Fundamental
Change if the Fundamental Change Election Notice is received by the Conversion
Agent subsequent to the Fundamental Change Effective Date and before the close
of business on the second Business Day immediately preceding the Fundamental
Change Election Date.

                                       79


          (f) A Holder may withdraw any Fundamental Change Election Notice (in
whole or in part) by a written notice of withdrawal delivered to the Paying
Agent prior to the close of business on the Business Day prior to the
Fundamental Change Election Date. The notice of withdrawal must state: (i) the
principal amount of the withdrawn Securities; (ii) if certificated Securities
have been issued, the certificate numbers of the withdrawn Securities; and (iii)
the principal amount, if any, that remains subject to the Fundamental Change
Election Notice.

     If the Securities are Global Securities, the withdrawal notice must comply
with the Applicable Procedures.

          (g) A Holder must either effect book-entry transfer or deliver the
Securities, together with necessary endorsements, to the office of the Paying
Agent after delivery of the Fundamental Change Election Notice to receive
payment of the Conversion Consideration. Holders will receive payment of the
Conversion Consideration promptly following the later of the Fundamental Change
Election Date or the time of book-entry transfer or the delivery of the
Securities to the Paying Agent. If the Paying Agent holds money or securities
sufficient to pay the Conversion Consideration of the Securities on the Business
Day following the Fundamental Change Election Date, then: (i) the Securities
will cease to be Outstanding and Interest, if any, will cease to accrue or
principal to accrete (whether or not book-entry transfer of the Securities is
made or whether or not the Security is delivered to the Paying Agent); and (ii)
all other rights of the Holder will terminate (other than the right to receive
the Conversion Consideration upon delivery or transfer of the Securities).

          Section 12.6 Exercise of Conversion Privilege. (a) In order to convert
a security other than in connection with a Fundamental Change (which is governed
by Section 12.5 above), the Holder of any Security to be converted must deliver
an irrevocable conversion notice substantially in the form set forth in Section
2.4 together with the Security (if the Security is in certificated form), duly
endorsed in blank, by the time required by Section 12.1 or 12.2, as the case may
be, to the Conversion Agent at any office or agency of the Company maintained
for that purpose pursuant to Section 10.2 (the date of such delivery of notice
and satisfaction of all other requirements for conversion, the "Conversion
Date"). Any Holder may obtain copies of the required form of the conversion
notice from the Conversion Agent. Upon conversion, the Company will satisfy its
conversion obligations with respect to the principal amount of the Securities to
be converted into Conversion Consideration.

          (b) The Conversion Agent will convert the Securities and the Company
will remit the Conversion Consideration as soon as practicable, but in no event
later than the third Business Day following the last day of the Applicable
Conversion Reference Period.

          (c) In the event any Holder surrenders any Security for conversion
during the period between the close of business on a Record Date but prior to
the corresponding Interest Payment Date, the Company shall pay accrued Interest
on such Security on that Interest Payment Date to the Holder of such Security as
of such Record Date. The Holder surrendering the Security for conversion shall
be required to pay to the Company an amount equal to the Interest that has
accrued as of such Interest Payment Date and that will be paid to the Holder of
such Security as of the Record Date. The preceding sentence does not apply to
Securities that are

                                       80


surrendered for conversion after the Company has specified a Redemption Date
that is after a Record Date but on or prior to the corresponding Interest
Payment Date.

          (d) Securities shall be deemed to have been converted immediately
prior to the close of business on the day of surrender of such Securities for
conversion in accordance with the foregoing provisions, and at such time the
rights of the Holders of such Securities as Holders shall cease, and the Person
or Persons entitled to receive any Common Stock issuable upon conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
at such time. As promptly as practicable on or after the Conversion Date, the
Company shall issue and deliver to the Trustee, for delivery to the Holder
(unless a different Person is indicated on the Conversion Notice), a certificate
or certificates for the number of full shares of Common Stock issuable upon
conversion as provided in clause (b) above, together with payment in lieu of any
fraction of a share, as provided in Section 12.8.

          (e) All shares of Common Stock delivered upon conversion of Restricted
Securities shall bear restrictive legends substantially in the form of the
legends required to be set forth on the Restricted Securities pursuant to
Section 3.6(h) and shall be subject to the restrictions on transfer provided in
such legends. Neither the Trustee nor any agent maintained for the purpose of
such conversion shall have any responsibility for the inclusion or content of
any such restrictive legends on such Common Stock; provided, however, that the
Trustee or any agent maintained for the purpose of such conversion shall have
provided, to the Company or to the Company's transfer agent for such Common
Stock, prior to or concurrently with a request to the Company to deliver such
Common Stock, written notice that the Securities delivered for conversion are
Restricted Securities.

          (f) In the case of any Security which is converted in part only, upon
such conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amount of such Security to be
converted is any integral multiple of U.S. $1,000 (but for purposes of such
denominations based on the Initial Principal Amount of such Securities) and the
principal amount of such security to remain Outstanding after such conversion is
equal to or in excess of U.S. $1,000.

          (g) If shares of Common Stock to be issued upon conversion of a
Restricted Security, or Securities to be issued upon conversion of a Restricted
Security in part only, are to be registered in a name other than that of the
beneficial owner of such Restricted Security, then such Holder must deliver to
the Conversion Agent a Surrender Certificate, dated the date of surrender of
such Restricted Security and signed by such beneficial owner, as to compliance
with the restrictions on transfer applicable to such Restricted Security.
Neither the Trustee nor any Conversion Agent, Registrar or transfer agent shall
be required to register in a name other than that of the beneficial owner,
shares of Common Stock issued upon conversion of any such Restricted Security
not so accompanied by a properly completed Surrender Certificate.

          Section 12.7 Exchange in Lieu of Conversion. When a Holder surrenders
Securities for conversion, the Conversion Agent may direct the Holder to
surrender the Securities

                                       81


to a financial institution designated by the Company for exchange in lieu of
conversion. In order to accept any Securities surrendered for conversion, the
designated institution must agree to deliver, in exchange for the Securities,
the Conversion Consideration. If the designated institution accepts any such
Securities, it will deliver the Conversion Consideration to the Conversion Agent
and the Conversion Agent will deliver that consideration to the Holder. Any
Securities exchanged by the designated institution will remain Outstanding. If
the designated institution agrees to accept any Securities for exchange but does
not timely deliver the related Conversion Consideration, the Company will, as
promptly as practical thereafter, but not later than the third Business Day
following the Applicable Conversion Response Period, convert the Securities and
deliver the Conversion Consideration owed upon such conversion.

     The Company's designation of an institution to which the Securities may be
submitted for exchange does not require the institution to accept any
Securities. If the designated institution declines to accept any Securities
surrendered for exchange, the Company will convert those Securities into the
cash payment and the number of shares of Common Stock, issuable upon conversion,
as described in this Article XII. The Company will not pay any consideration to,
or otherwise enter into any arrangement with, the designated institution for or
with respect to such designation.

          Section 12.8 Fractions of Shares. (a) No fractional shares of Common
Stock shall be issued upon conversion of any Security or Securities. Instead of
any fractional shares of Common Stock that would otherwise be issued upon
conversion of the Securities, the Company will pay a cash amount (calculated to
the nearest cent) equal to the value of such fractional shares, based on the
Closing Price on the last Trading Day of the Applicable Conversion Reference
Period.

          (b) For purposes of paragraphs (a) above, if more than one Security
shall be surrendered for conversion at one time by a Holder, the number of full
shares of Common Stock which shall be issuable upon conversion thereof shall be
computed on the basis of the aggregate principal amount of the Securities (or
specified portions thereof) so surrendered.

          Section 12.9 Anti-Dilution Adjustments. The Capped Anti-Dilution
Multiplier and the Uncapped Anti-Dilution Multiplier will be subject to
adjustment, without duplication, as follows upon the occurrence of any of the
following events:

          (a) Stock Splits and Combinations. In the event that the outstanding
shares of Common Stock shall be subdivided, split or recombined (including an
effective subdivision of Common Stock through the reclassification of Common
Stock), the Uncapped Anti-Dilution Multiplier in effect immediately before the
close of business on the record date fixed for such subdivision, split or
recombination becomes effective shall be proportionately increased or reduced.

          (b) Stock Dividends. In the event that the Company pays a dividend or
makes a distribution on Common Stock, payable exclusively in shares of Common
Stock, the Uncapped Anti-Dilution Multiplier in effect immediately before the
close of business on the record date

                                       82


fixed for the determination of stockholders entitled to receive such dividend or
other distribution shall be adjusted by multiplying it by a fraction:

          (i) the numerator of which shall be (A) the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination, plus (B) the total number of shares constituting the dividend or
distribution; and

          (ii) the denominator of which shall be the number of shares of Common
Stock outstanding on the record date fixed for such dividend or distribution.

     If, after any such date fixed for determination, any dividend or
distribution is not in fact paid, the Uncapped Anti-Dilution Multiplier shall be
immediately readjusted, effective as of the date the Board of Directors
determines not to pay such dividend or distribution, to the Uncapped
Anti-Dilution Multiplier that would have been in effect if such determination
date had not been fixed.

          (c) Issuance of Rights or Warrants. In the event that the Company
issues to all or substantially all holders of Common Stock rights, options or
warrants (other than pursuant to any dividend reinvestment or share purchase or
similar plan) entitling such holders to subscribe for or purchase shares of
Common Stock for a period expiring within 60 days from the date of issuance of
the rights, options or warrants at less than the Current Market Price per share
of the Common Stock on the date fixed for the determination of stockholders
entitled to receive such rights, options or warrants, the Uncapped Anti-Dilution
Multiplier in effect immediately before the close of business on the record date
fixed for such determination shall be increased by multiplying it by a fraction:

          (i) the numerator of which shall be (A) the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination plus (B) the total number of shares of Common Stock so offered for
subscription or purchase;

          (ii) the denominator of which shall be the sum of (A) the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus (B) the total number of shares of Common Stock that
the aggregate offering price of the total number of shares offered for
subscription or purchase would purchase at the Current Market Price.

     If, after any such date fixed for determination, any such rights, options
or warrants are not in fact exercised prior to the expiration thereof (and as a
result no additional shares of Common Stock are delivered or issued pursuant to
such rights, options or warrants), the Uncapped Anti-Dilution Multiplier shall
be immediately readjusted, to the Uncapped Anti-Dilution Multiplier that would
then be in effect had the adjustments made upon the issuance of such rights,
options or warrants been made on the basis of delivery or issuance of only the
number of shares of Common Stock actually delivered or issued.

     "Current Market Price" of the Common Stock (unless otherwise stated below)
means the average of the Closing Prices of the Common Stock for the five
consecutive Trading Days ending on the earlier of the record date fixed for
determination of the stockholders entitled to

                                       83


receive such distribution (if such record date is a Trading Day or, if not, then
on the last Trading Day prior to such record date) and the day before the
ex-dividend date for such distribution.

          (d) Spin-Offs. In the event the Company pays a dividend or makes a
distribution of shares of capital stock of any class or series, or similar
equity interests, of or relating to a Subsidiary of the Company or other
business unit ("Spin-Off"), the Uncapped Anti-Dilution Multiplier in effect
immediately before the close of business on the record date fixed for
determination of stockholders entitled to receive that distribution will be
increased by multiplying it by a fraction equal to the sum of the Daily
Adjustments for each of the ten consecutive Trading Days beginning on the
effective date of the Spin-Off. The "Daily Adjustment" for any given Trading Day
is equal to a fraction:

          (i) the numerator of which is the Closing Price of the Common Stock on
that Trading Day plus the Closing Price of the portion of those shares of
capital stock or similar equity interests so distributed applicable to one share
of Common Stock on that Trading Day; and

          (ii) the denominator of which is the product of (a) 10 and (b) the
Closing Price of the Common Stock on that Trading Day.

     The adjustment to the Uncapped Anti-Dilution Multiplier in the event of a
Spin-Off will take effect at the opening of business on the tenth Trading Day
from, and including, the effective date of the Spin-Off.

          (e) Cash Dividends or Distributions. In the event the Company makes
regular quarterly, semi-annual or annual cash dividends or distribution
consisting exclusively of cash to all or substantially all holders of the Common
Stock, the Uncapped Anti-Dilution Multiplier in effect immediately before the
close of business on the record date fixed for such dividend or distribution
will be increased by multiplying it by a fraction:

          (i) the numerator of which is the Current Market Price of the Common
Stock; and

          (ii) the denominator of which is the Current Market Price of the
Common Stock, minus the amount per share of such dividend or distribution.

     In the event the Company makes other dividends or distributions consisting
exclusively of cash to all or substantially all holders of Common Stock
(excluding any dividends or distribution in connection with the Company's
liquidation, dissolution or winding up), the Uncapped Anti-Dilution Multiplier
will be increased by multiplying it by the fraction set forth above.

     Notwithstanding the foregoing, in cases where (i) the amount per share of
Common Stock of such distribution equals or exceeds the Current Market Price of
the Common Stock or (ii) the Current Market Price of the Common Stock exceeds
the amount per share of Common Stock of such distribution by less than $1.00, in
lieu of making the foregoing adjustment, the Company will have the right to
adjust a Holder's conversion right such that such Holder will receive upon
conversion, in addition to cash and shares of Common Stock, if any, the
distribution the Holder

                                       84


would have received if the Holder had held a number of shares equal to the
product of (i) 37.5090 and (ii) the Parity Share Number then in effect
immediately prior to the record date for such distribution or dividend. If the
Company elects to adjust the Holders' conversion rights as contemplated by this
paragraph, the Company will promptly notify the Trustee, the Conversion Agent
and the Holders of such election.

          (f) Distributions of Indebtedness, Securities or Assets. In the event
the Company distributes to all or substantially all holders of Common Stock
evidences of indebtedness, securities or other assets or any other rights,
options or warrants to purchase its securities (the "distributed assets"), but
excluding:

          (i) dividends or distributions described in Section 12.9(b);

          (ii) rights or warrants described in Section 12.9(c)

          (iii) dividends or distributions in connection with a Spin-Off
described in Section 12.9(d); and

          (iv) dividends or distributions paid exclusively in cash described in
Section 12.9(e);

the Uncapped Anti-Dilution Multiplier in effect immediately before the close of
business on the record date fixed for determination of stockholders entitled to
receive that distribution will be increased by multiplying it by a fraction:

          (i) the numerator of which is the Current Market Price of the Common
Stock; and

          (ii) the denominator of which is the Current Market Price of the
Common Stock minus the fair market value, as determined by the Board of
Directors, whose determination in good faith will be conclusive, of the portion
of those distributed assets applicable to one share of Common Stock.

     Notwithstanding the foregoing, in cases where (i) the fair market value per
share of Common Stock of the distributed assets equals or exceeds the Current
Market Price of the Common Stock, or (ii) the Current Market Price of the Common
Stock exceeds the fair market value per share of Common Stock of the distributed
assets by less than $1.00, in lieu of making the foregoing adjustment, the
Company will have the right to adjust the conversion rights of the Securities
such that a Holder will receive upon conversion, in addition to cash and shares
of Common Stock, the distributed assets the Holder would have received if the
Holder had held a number of shares of Common Stock equal to the product of
37.5090 and the Parity Share Number then in effect immediately prior to the
record date for such distribution of assets.

          (g) Repurchases. In the event the Company or one of its Subsidiaries
makes a payment in respect of a repurchase of Common Stock, the consideration
for which exceeds the Then-Prevailing Market Price of the Common Stock (such
amount being the "Repurchase Premium"), and that repurchase, together with any
other repurchases of Common Stock by the Company or a Subsidiary of the Company
involving a Repurchase Premium concluded within

                                       85


the preceding 12 months, results in the payment by the Company (or its
Subsidiary) of an aggregate consideration exceeding an amount equal to 10% of
the Market Capitalization of the Common Stock, the Uncapped Anti-Dilution
Multiplier in effect immediately before the close of business on the day of such
payment in respect of a repurchase will be increased by multiplying it by a
fraction:

          (i) the numerator of which shall be the Current Market Price of the
Common Stock; and

          (ii) the denominator of which shall be (A) the Current Market Price of
the Common Stock, minus (B) the quotient of (1) the aggregate amount of all of
the Repurchase Premiums paid in connection with such repurchases and (2) the
number of shares of Common Stock outstanding on the day next succeeding the date
of the repurchase triggering the adjustment, as determined by the Board of
Directors;

provided that no adjustment to the Uncapped Anti-Dilution Multiplier shall be
made to the extent the Uncapped Anti-Dilution Multiplier is not increased as a
result of the above calculation and; provided further that the repurchases of
Common Stock effected by the Company, any of its Subsidiaries or their
respective agents in conformity with Rule 10b-18 under the Exchange Act will not
be included in any adjustment to the Uncapped Anti-Dilution Multiplier made
under this Section 12.9(g).

     For purposes of this Section 12.9(g):

          (i) "Market Capitalization" will be calculated by multiplying (A) the
Current Market Price of the Common Stock by (B) the number of shares of Common
Stock then outstanding on the date of the repurchase triggering the adjustment;

          (ii) "Current Market Price" will be the average of the Closing Prices
of the Common Stock for the five consecutive Trading Days beginning on the
Trading Day next succeeding the date of the repurchase triggering the
adjustment; and

          (iii) in determining the Repurchase Premium, the "Then-Prevailing
Market Price" of the Common Stock will be the average of the Closing Prices of
the Common Stock for the five consecutive Trading Days ending on the relevant
repurchase date.

          (h) Tender or Exchange Offers. In the event the Company or one of its
Subsidiaries makes a payment in respect of a tender offer or exchange offer for
Common Stock, to the extent the cash and value of any other consideration
included in the payment per share of the Common Stock exceeds the Closing Price
of the Common Stock on the Trading Day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender offer or exchange
offer, as the case may be, the Uncapped Anti-Dilution Multiplier in effect
immediately before the close of business on the date fixed for the consummation
of such tender or exchange offer will be increased by multiplying it by a
fraction:

          (i) the numerator of which shall be the sum of (A) the fair market
value, as determined by the Board of Directors of the aggregate consideration
payable for all shares of Common Stock the Company or any such Subsidiary
purchases in the tender or exchange offer

                                       86


and (B) the product of (1) the number of shares of Common Stock outstanding on
the date of consummation of such tender or exchange offer less any such
purchased shares and (2) the Closing Price of the Common Stock on the Trading
Day next succeeding the date of the expiration of the tender or exchange offer;
and

          (ii) the denominator of which shall be the product of (A) the number
of shares of Common Stock outstanding on the date of consummation of such tender
or exchange offer, including any such purchased shares, and (B) the Closing
Price of the Common Stock on the Trading Day next succeeding the date of
expiration of the tender or exchange offer;

          (i) In addition to the adjustments set forth above, the Company may
increase the Parity Share Number as the Board of Directors considers advisable
to avoid or diminish any income tax to holders of Common Stock or rights to
purchase Common Stock resulting from any dividend or distribution of capital
stock (or rights to acquire capital stock) or from any event treated as such for
income tax purposes. The Company may also, from time to time, to the extent
permitted by applicable law, increase the Parity Share Number by any amount for
any period of at least 20 days if the Board of Directors has determined that
such increase would be in the Company's best interests. If the Board of
Directors makes such a determination, it will be conclusive. The Company will
give Holders at least 15 days' notice of such an increase in the Parity Share
Number.

     No adjustment to the Parity Share Number or a Holder's ability to convert
its Securities will be made if the Holder otherwise participated in the
distribution without conversion.

     Notwithstanding the foregoing provisions of this Section 12.9, neither the
Capped Anti-Dilution Multiplier nor the Uncapped Anti-Dilution Multiplier will
be adjusted:

          (i) upon the issuance of any shares of Common Stock pursuant to any
present or future plan providing for the reinvestment of dividends or interest
payable on the Company's securities and the investment of additional optional
amounts in shares of Common Stock under any plan;

          (ii) upon the issuance of any shares of Common Stock or options or
rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or
any of its Subsidiaries;

          (iii) upon the issuance of any shares of Common Stock pursuant to any
option, warrant, right or exercisable, exchangeable or convertible security not
described in the preceding clause and outstanding as of the date the Securities
were first issued;

          (iv) for a change in the par value of the Common Stock; or

          (v) for accrued and unpaid Interest, if any.

     Holders will receive, upon conversion of their Securities, in addition to
cash and Common Stock, as the case may be, the rights under any stockholder
rights plan the Company may adopt, unless prior to such conversion a Trigger
Event (as defined in Section 12.17) shall

                                       87


have occurred, in which case the Uncapped Anti-Dilution Multiplier will be
adjusted at the time of the Trigger Event as described in Section 12.9(f).

     Simultaneously with an adjustment to the Capped Anti-Dilution Multiplier or
the Uncapped Anti-Dilution Multiplier, as the case may be, the Company will
disseminate a Press Release detailing the new Capped Anti-Dilution Multiplier,
the Uncapped Anti-Dilution Multiplier and Parity Share Number and other relevant
information.

          Section 12.10 Adjustment to Capped Anti-Dilution Multiplier In
Connection With a Change in Control. (a) If a Change in Control occurs prior to
September 30, 2010, the Capped Anti-Dilution Multiplier in effect immediately
before the close of business on the date on which such Change in Control
transaction becomes effective (the "Change in Control Effective Date") will be
increased by multiplying it by a factor (the "Adjustment Factor") determined by
reference to the table set forth below in Section 12.10(b) based on the Change
in Control Effective Date and the Change in Control Price (as defined below). If
holders of Common Stock receive only cash in a Change in Control transaction,
the "Change in Control Price" shall be the cash amount paid per share multiplied
by the Parity Share Number then in effect. Otherwise, the Change in Control
Price will be the average of the Parity Prices of the Common Stock on each of
the ten consecutive Trading Days prior to but not including the Change in
Control Effective Date.

          (b) The following table sets forth the Change in Control Prices and
Adjustment Factors for a Security with an Initial Principal Amount of $1,000:



                                                           Change in Control Price

Change in
Control           $20.91 $22.50 $25.00  $27.50 $30.00 $35.00 $40.00  $45.00 $50.00 $60.00  $70.00 $80.00 $90.00  $100.00 $120.00

          (c) In the event that the exact Change in Control Price and Change in
Control Effective Date are not set forth in Section 12.10(b), if the Change in
Control Price is:

          (i) between two Change in Control Price amounts on the table or the
Change in Control Effective Date is between two dates on the table, the
Adjustment Factor will be determined by straight-line interpolation between the
Adjustment Factor set forth for the higher and lower Change in Control Price
amounts and the two Change in Control Effective Dates, as applicable, based on a
365-day year;

          (ii) more than $120.00 per share, no adjustment will be made; and

          (iii) less than $20.91 per share, no adjustment will be made.

                                       88


          (d) Notwithstanding the provisions of this Section 12.10, in no event
will the Capped Adjustment Multiplier exceed 1.2750.

          (e) The adjustment to the Capped Anti-Dilution Multiplier pursuant to
this Section 12.10 will occur on the Change in Control Effective Date and will
remain in effect only for purposes of determining the number of shares a Holder
is entitled to receive if such Holder submits a Fundamental Change Election
Notice and converts such Holder's Securities in connection with the Change in
Control.

          Section 12.11 Notice of Adjustments. Whenever the Capped Anti-Dilution
Multiplier or the Uncapped Anti-Dilution Multiplier is adjusted as herein
provided:

          (a) the Company shall compute the adjusted Parity Share Number in
accordance with Section 12.9 and 12.10 and shall prepare a certificate signed by
its principal financial officer, Comptroller or Treasurer of the Company setting
forth the adjusted Parity Share Number (and the Capped Anti-Dilution Multiplier
and/or the Uncapped Anti-Dilution Multiplier, as the case may be) and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall promptly be filed with the Trustee and with each Conversion
Agent; and

          (b) upon each such adjustment, a notice stating that the Parity Share
Number has been adjusted and setting forth the adjusted Parity Share Number
shall be required, and as soon as practicable after it is required, such notice
shall be provided by the Company to all Holders in accordance with Section 1.6.

     Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours, and shall not be deemed to have knowledge of any adjustment in the Capped
Anti-Dilution Multiplier, the Uncapped Anti-Dilution Multiplier or the Parity
Share Number unless and until a Responsible Officer of the Trustee shall have
received such a certificate. Until a Responsible Officer of the Trustee receives
such a certificate, the Trustee and each Conversion Agent may assume without
inquiry that the last Parity Share Number of which the Trustee has knowledge
remains in effect.

          Section 12.12 Notice of Certain Corporate Action. In case:

          (a) the Company shall declare a dividend (or any other distribution)
on its Common Stock payable (i) otherwise than exclusively in cash or (ii)
exclusively in cash in an amount that would require any adjustment pursuant to
Section 12.9; or

          (b) the Company shall authorize the granting to all or substantially
all of the holders of its Common Stock of rights, options or warrants to
subscribe for or purchase any shares of capital stock of any class or of any
other rights; or

          (c) of any reclassification of the Common Stock, or of any
consolidation, merger or share exchange to which the Company is a party and for
which approval of any

                                       89


stockholders of the Company is required, or of the conveyance, sale, transfer or
lease (other than a mere grant of security interest) of all or substantially all
of the assets of the Company; or

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

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.2, and shall
cause to be provided to all Holders in accordance with Section 1.6, at least 20
days (or 10 days in any case specified in clause (a) or (b) above and 30 days
for clause (c) above) prior to the applicable record or effective date
hereinafter specified, a notice stating (i) the date on which a record is to be
taken for the purpose of such dividend, distribution, rights, options or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights,
options or warrants are to be determined or (ii) the date on which such
reclassification, consolidation, merger, conveyance, transfer, sale, lease,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record will be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger,
conveyance, transfer, sale, lease, dissolution, liquidation or winding up.
Neither the failure to give such notice or the notice referred to in the
following paragraph nor any defect therein shall affect the legality or validity
of the proceedings described in clauses (a) through (d) of this Section. If at
the time the Trustee shall not be the Conversion Agent, a copy of such notice
shall also forthwith be filed by the Company with the Trustee.

     The Company shall cause to be filed at the Corporate Trust Office and each
office or agency maintained for the purpose of conversion of Securities pursuant
to Section 10.2, and shall cause to be provided to all Holders in accordance
with Section 1.6, notice of any tender offer by the Company or any Subsidiary
for all or any portion of the Common Stock at or about the time that such notice
of tender offer is provided to the public generally.

          Section 12.13 Company to Provide Common Stock. As soon as practicable,
the Company shall reserve for issuance upon conversion of Securities an amount
of shares of Common Stock sufficient for the purpose of effecting the conversion
of all of the Outstanding Securities.

          Section 12.14 Taxes on Conversions. Except as provided in the next
sentence, the Company will pay all stamp taxes and other duties that may be
payable in respect of the issue or delivery of shares of Common Stock on
conversion of Securities pursuant to Article XII. The Company shall not,
however, be required to pay any tax or duty (i) in respect of income of the
Holder or (ii) caused by a Holder's request that the shares of Common Stock
deliverable upon conversion be issued in a name other than its own. Certificates
representing shares of Common Stock will be issued or delivered only after all
applicable taxes and duties payable by the Holder, if any, are paid.

     The Company agrees, and each Holder is deemed to agree, that delivery to
such Holder of the full number of shares of Common Stock into which each
Security is convertible, together with the cash portion of any Conversion
Consideration and any cash payment of such Holder's

                                       90


fractional shares in accordance with Section 12.8, will be treated as a
contingent payment (in an amount equal to the sum of the then Fair Market Value
of such Common Stock and such cash payment, if any) on the Securities for
purposes of the Contingent Payment Debt Regulations governing contingent payment
debt obligations.

     If the Conversion Consideration paid by the Company to a Holder upon
conversion of the Securities pursuant to this Article XII is not sufficient to
allow the Company to comply with the U.S. federal withholding tax obligations
imposed by the Code with respect to accrued and unpaid Interest on the
Securities payable to the beneficial owner of such Securities, the Company may,
to the extent required by applicable law, recoup or set-off such liability
against any amounts owed to such Holder, including, but not limited to, the
shares of Common Stock to be issued upon conversion to such beneficial owner or
any actual cash dividends or distributions subsequently made with respect to
such shares of Common Stock to such beneficial owner.

     If the Parity Share Number is adjusted pursuant to this Indenture, to the
extent such adjustment results in a constructive distribution to beneficial
owners of Securities under Section 305 of the Code, which distribution gives
rise to a U.S. federal withholding tax liability, the Company may, to the extent
required by law, recoup or set-off such liability against any payments (whether
in cash or Common Stock) made with respect to the Securities (or any payment
with respect to Common Stock received upon conversion thereof) to such
beneficial owners.

          Section 12.15 Covenant as to Common Stock. The Company agrees that all
shares of Common Stock that may be delivered upon conversion of Securities, upon
such delivery, will be newly issued shares and will have been duly authorized
and validly issued and will be fully paid and nonassessable and, except as
provided in Section 12.14, the Company will pay all taxes, liens and charges
with respect to the issue thereof.

          Section 12.16 Cancellation of Converted Securities. All Securities
delivered for conversion shall be delivered to the Trustee or its agent to be
canceled by or at the direction of the Trustee, which shall dispose of the same
as provided in Section 3.13.

          Section 12.17 Rights Issued in Respect of Common Stock. Rights or
warrants distributed by the Company to all holders of Common Stock entitling the
holders thereof to subscribe for or purchase shares of the Company's capital
stock (either initially or under certain circumstances), which rights or
warrants, until the occurrence of a specified event or events identified in the
instruments governing such rights or warrants ("Trigger Event"):

          (a) are deemed to be transferred with such shares of Common Stock,

          (b) are not exercisable, and

          (c) are also issued in respect of future issuances of Common Stock,

shall not be deemed distributed for purposes of Section 12.9(f) until the
occurrence of the earliest Trigger Event. In addition, in the event of any
distribution of rights or warrants, or any Trigger Event with respect thereto,
that shall have resulted in an adjustment to the Uncapped Ant-Dilution
Multiplier under Section 12.9(f), (1) in the case of any such rights or warrants
that shall

                                       91


all have been redeemed or repurchased without exercise by any holders thereof,
the Uncapped Ant-Dilution Multiplier shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger Event,
as the case may be, as though it were a cash distribution, equal to the per
share redemption or repurchase price received by a holder of Common Stock with
respect to such rights or warrants (assuming such holder had retained such
rights or warrants), made to all holders of Common Stock as of the date of such
redemption or repurchase, and (2) in the case of any such rights or warrants all
of which shall have expired without exercise by any holder thereof, the Uncapped
Ant-Dilution Multiplier shall be readjusted as if such issuance had not
occurred.

          Section 12.18 Responsibility of Trustee for Conversion Provisions. The
Trustee, subject to the provisions of Section 6.1, and any Conversion Agent
shall not at any time be under any duty or responsibility to any Holder of
Securities to determine whether any facts exist that may require any adjustment
of the Parity Share Number, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, herein or in any
supplemental indenture provided to be employed, in making the same, or whether a
supplemental indenture need be entered into. Neither the Trustee, subject to the
provisions of Section 6.1, nor any Conversion Agent shall be accountable with
respect to the validity or value (or the kind or amount) of any Common Stock, or
of any other securities or property or cash, which may at any time be issued or
delivered upon the conversion of any Security; and it or they do not make any
representation with respect thereto. Neither the Trustee, subject to the
provisions of Section 6.1, nor any Conversion Agent shall be responsible for any
failure of the Company to make or calculate any cash payment or to issue,
transfer or deliver any shares of Common Stock or share certificates or other
securities or property or cash upon the surrender of any Security for the
purpose of conversion; and the Trustee, subject to the provisions of Section
6.1, and any Conversion Agent shall not be responsible for any failure of the
Company to comply with any of the covenants of the Company contained in this
Article.

                                  ARTICLE XIII
                            REPURCHASE OF SECURITIES

          Section 13.1 Repurchase Rights. (a) Holders will have the right to
require the Company to repurchase the Securities on September 30, 2010,
September 30, 2015, September 30, 2020, September 30, 2025 and September 30,
2030 (each such date, a "Repurchase Date"). The repurchase price payable will be
equal to 100% of the Accreted Principal Amount of the Securities to be
repurchased, plus accrued and unpaid Interest, if any, to, but not including,
the applicable Repurchase Date (the "Repurchase Price"). The Company will be
required to repurchase any outstanding Securities for which a Holder delivers a
written repurchase notice to the Paying Agent substantially in the form in
Section 2.2 (the "Repurchase Notice"). Such notice must be delivered by a Holder
during the period beginning at any time from the opening of business on the date
that is 22 Business Days prior to the relevant Repurchase Date until the close
of business on the second Business Day prior to the applicable Repurchase Date.
If the Repurchase Notice is given and withdrawn during such period, the Company
will not be obligated to repurchase the related Securities. The Company will pay
the Repurchase Price for any Securities submitted for repurchase on the
Repurchase Date solely in cash.

                                       92


          (b) The Company will give notice to each Holder in accordance with
Section 1.6 at least 22 Business Days prior to each Repurchase Date as required
by applicable law, stating, among other things, the procedures that Holders must
follow to require the Company to repurchase the Securities.

          (c) The Repurchase Notice given by each Holder electing to require the
Company to repurchase Securities on the Repurchase Date must be given so as to
be received by the Paying Agent no later than the close of business on the
second Business Day immediately preceding the Repurchase Date and must state:
(i) if certificated, the certificate numbers of the Securities to be delivered
for repurchase; (ii) the portion of the Initial Principal Amount of Securities
to be repurchased, which must be $1,000 or an integral multiple thereof; and
(iii) that the Securities are to be repurchased by the Company pursuant to the
applicable provisions of the Securities and this Indenture.

     If the Securities are Global Securities, the withdrawal notice must comply
with the Applicable Procedures.

          (d) A Holder may withdraw any Repurchase Notice by delivering a
written notice of withdrawal to the Paying Agent prior to the close of business
on the second Business Day immediately preceding the applicable Repurchase Date.
The notice of withdrawal must state: (i) the Initial Principal Amount of
Securities being withdrawn; (ii) if certificated, the certificate numbers of the
Securities being withdrawn; and (iii) the Initial Principal Amount, if any, of
the Securities that remain subject to the Repurchase Notice.

     If the Securities are Global Securities, the withdrawal notice must comply
with the Applicable Procedures.

          (e) In connection with any repurchase, the Company will, to the extent
applicable: (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any
other tender offer rules under the Exchange Act which may then be applicable;
and (ii) file a Schedule TO and any other required schedule under the Exchange
Act.

          (f) The Company's obligation to pay the Repurchase Price for
Securities for which a Repurchase Notice has been delivered and not validly
withdrawn is conditioned upon the following: A Holder must either effect
book-entry transfer or deliver the Securities (if they are in certificated
form), together with necessary endorsements, to the office of the Paying Agent
after delivery of the Repurchase Notice to receive payment of the Repurchase
Price. The Company will cause the Repurchase Price for the Securities to be paid
promptly following the later of the applicable Repurchase Date or the time of
book-entry transfer or delivery of the Securities, together with such
endorsements.

          (g) The Company shall deposit cash, at the time and in the manner
contemplated by Section 11.5, sufficient to pay the Repurchase Price of all
Securities to be repurchased hereunder. If the Paying Agent holds money
sufficient to pay the Repurchase Price of the Securities for which a Repurchase
Notice has been given on the second Business Day immediately following the
applicable Repurchase Date in accordance with the terms of this Indenture, then,
immediately after such Repurchase Date, the Securities will cease to be

                                       93


Outstanding and Interest, if any, on the Securities will cease to accrue,
whether or not the Securities are delivered to the Paying Agent, and all other
rights of the Holder shall terminate, other than the right to receive the
Repurchase Price upon delivery of the Securities.

          Section 13.2 Exchange in Lieu of Repurchase. If a Holder exercises its
right to require the Company to repurchase any of such Holder's Securities
pursuant to Section 13.1 hereof, the Company may cause the Securities first to
be offered to a financial institution chosen by the Company for exchange in lieu
of repurchase. In order to accept any Securities surrendered for repurchase, the
designated institution must agree to deliver, in exchange for such Securities,
the Repurchase Price for such Securities that the Holder of such Securities
would otherwise receive upon repurchase by the Company. If the designated
institution accepts any such Securities for repurchase, it will deliver the
Repurchase Price to the Paying Agent. Any Securities purchased by the designated
institution will remain Outstanding. If the designated institution agrees to
accept any Securities for repurchase but does not timely deliver the related
Repurchase Price payment, the Company will, as promptly as practical thereafter,
but not later than one Business Day following the applicable Repurchase Date,
cause the Repurchase Price for the Securities to be paid; provided, however, if
such designated institution declines to accept any Securities surrendered for
repurchase, the Company will repurchase the Securities pursuant to Section 13.1
hereof.

     The Company will not pay any consideration to, or otherwise enter into any
arrangement with, the designated institution for or with respect to such
designation.

the Trustee in its capacity as Security Registrar. The Trustee may destroy any

their rights under this

Indenture or under the Securities, and the corresponding rights, and duties of
the Trustee, shall be as provided by the Trust Indenture Act.

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

          Section 14.3 Reports by Trustee. (a) After this Indenture has been
qualified under the Trust Indenture Act, the Trustee shall transmit to Holders
such reports concerning the Trustee and its actions under this Indenture as may
be required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant thereto.

          (b) After this Indenture has been qualified under the Trust Indenture
Act, a copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which the
Securities are listed, with the Commission and with the Company. The Company
will notify the Trustee when the Securities are listed on any stock exchange.

          Section 14.4 Reports by Company. After this Indenture has been
qualified under the Trust Indenture Act, the Company shall file with the Trustee
and the Commission, and transmit to Holders, such information, documents and
other reports, and such summaries thereof, as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant to such
Act; provided that any such information, documents or reports required to be
filed with the Commission pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 shall be filed with the Trustee within 15 days after the
same is filed with the Commission.

          Section 14.5 Calculations in Respect of Securities. The Company will
be responsible for making any calculations called for under the Securities.
These calculations include, but are not limited to, determinations of the
Trading Price of the Securities and the Closing Price of the Common Stock, any
accrued Interest payable on the Securities, the Capped Anti-Dilution Multiplier,
the Uncapped Anti-Dilution Multiplier, the Parity Share Number and the projected
payment schedule with respect to the Securities. The Company will make these
calculations in good faith and, absent manifest error, its calculations will be
final and binding on the Holders of Securities. The Company will provide a
schedule of its calculations to the Trustee, and the Trustee is entitled to rely
upon the accuracy of the Company's calculations without independent
verification. The Trustee will forward the Company's calculations to any Holder
of Securities upon a written request by such Holder.
