          SECTION 1.05   Acts of Holders.

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

          (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 electronic delivery) or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing or delivering such instrument or writing
acknowledged to such officer the execution (or electronic delivery) thereof.
When such execution is by a signer acting in a capacity other than such signer's
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of such signer's authority. The fact and date of the execution
of any such instrument or writing (electronic or otherwise), or the authority of
the Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

          (c)  The ownership of Securities shall be proved by the register
maintained by the Registrar.

          (d)  Any request, demand, authorization, direction, notice, consent,
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.

          (e)  If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a resolution of the Board of
Directors, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other Act may be given before or after such record
date, but only the Holders of record at the close of business on such record
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of outstanding Securities have authorized or
agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other

                                       9

<PAGE>

Act, and for that purpose the outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture within six months after
the record date.

                                   ARTICLE 2
                                 THE SECURITIES

          SECTION 2.01   Form and Dating. The Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibits A-1
and A-2 attached hereto, which are a part of this Indenture. The Securities may
have notations, legends or endorsements required by law, stock exchange rule or
usage (provided that any such notation, legend or endorsement required by usage
is in a form acceptable to the Company). The Company shall provide any such
notations, legends or endorsements to the Trustee in writing. Each Security
shall be dated the date of its authentication.

          (a)  144A Global Securities. Securities offered and sold within the
United States to "qualified institutional buyers" as defined in Rule 144A
("QIBs") in reliance on Rule 144A shall be issued initially in the form of a
144A Global Security, which shall be deposited with the Trustee at its Corporate
Trust Office, as custodian for the Depositary and registered in the name of The
Depository Trust Company ("DTC") or the nominee thereof (such depositary, or any
successor thereto, and any such nominee being hereinafter referred to as the
"Depositary") duly executed by the Company and authenticated by the Trustee as
hereinafter provided. The aggregate Principal Amount at Maturity of the 144A
Global Securities may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depositary as hereinafter provided.

          (b)  Institutional Accredited Investor Securities. Except as provided
in Section 2.12(f)(i) and in this Section 2.01, 2.06 or the remainder of Section
2.12 hereof, owners of beneficial interests in Global Securities will not be
entitled to receive physical delivery of Certificated Securities. Securities
offered and sold within the United States to institutional "accredited
investors" as defined in Rule 501(a)(1), (2), (3) and (7) under the Securities
Act ("Institutional Accredited Investors") shall be issued, if in the form of
Certificated Securities, initially in the form of an Institutional Accredited
Investor Security, duly executed by the Company and authenticated by the Trustee
as hereinafter provided.

          (c)  Global Securities in General. Each Global Security shall
represent such of the outstanding Securities as shall be specified therein and
each shall provide that it shall represent the aggregate Principal Amount at
Maturity of outstanding Securities from time to time endorsed thereon and that
the aggregate Principal Amount at Maturity of outstanding Securities represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges, redemptions and conversions.

          Any adjustment of the aggregate Principal Amount at Maturity of a
Global Security to reflect the amount of any increase or decrease in the
Principal Amount at Maturity of outstanding Securities represented thereby shall
be made by the Trustee in accordance with

                                       10

<PAGE>

instructions given by the Holder thereof as required by Section 2.12 hereof and
shall be made on the records of the Trustee and the Depositary.

          (d)  Book-Entry Provisions. This Section 2.01(d) shall apply only to
Global Securities deposited with or on behalf of the Depositary.

          The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(d), authenticate and deliver initially one or more Global
Securities that (i) shall be registered in the name of the Depositary, (ii)
shall be delivered by the Trustee to the Depositary or pursuant to the
Depositary's instructions or held by the Trustee as custodian for such
Depositary and (iii) shall bear legends substantially to the following effect:

     "UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
     REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE ISSUER OR
     ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND
     ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR
     IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED
     REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT
     HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
     REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
     COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
     OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED
     OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS,
     IN WHOLE BUT NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST
     COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND
     TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO
     TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN
     ARTICLE TWO OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF."

          (e)  Certificated Securities. Securities not issued as interests in
the Global Securities will be issued in certificated form substantially in the
form of Exhibit A-2 attached hereto.

          (f)  U.S. Tax Legend. All Securities shall bear the following legend:

          THIS NOTE WAS ISSUED WITH ORIGINAL ISSUE DISCOUNT, FOR PURPOSES OF
     SECTIONS 1272, 1273 AND 1275 OF THE UNITED STATES INTERNAL REVENUE CODE OF
     1986, AS AMENDED. THE ISSUE PRICE OF THIS NOTE WAS $475.00 PER $1,000 OF
     PRINCIPAL AMOUNT AT MATURITY; THE AMOUNT OF ORIGINAL ISSUE DISCOUNT,
     INCLUDING CASH INTEREST PAYABLE THROUGH MAY 14, 2007 TAXABLE AS ORIGINAL
     ISSUE DISCOUNT UNDER TREASURY REGULATION SECTION 1.1273-1, IS $2,378.67 PER
     $1,000

                                  11

<PAGE>

     OF PRINCIPAL AMOUNT AT MATURITY; THE ISSUE DATE IS MAY 14, 2002; AND THE
     YIELD TO MATURITY FOR THE PURPOSES OF ACCRUING TAX ORIGINAL ISSUE DISCOUNT
     IS 6.90% PER ANNUM, CALCULATED ON A SEMIANNUAL BOND EQUIVALENT BASIS.

          SECTION 2.02   Execution and Authentication. The Securities shall be
executed on behalf of the Company by any Officer. The signature of the Officer
on the Securities may be manual or facsimile.

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

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

          The Trustee shall authenticate and deliver Securities for original
issue in an aggregate Principal Amount at Maturity of up to $368,500,000 upon a
Company Order without any further action by the Company. The aggregate Principal
Amount at Maturity of Securities outstanding at any time may not exceed the
amount set forth in the foregoing sentence, except as provided in Section 2.07
hereof

          The Securities shall be issued only in registered form without coupons
and only in denominations of $1,000 of Principal Amount at Maturity and any
integral multiple thereof.

          SECTION 2.03   Registrar, Paying Agent, Conversion Agent and Bid
Calculation Agent. The Company shall maintain an office or agency where
Securities may be presented for registration of transfer or for exchange
("Registrar"), an office or agency where Securities may be presented for
purchase or payment ("Paying Agent") and an office or agency where Securities
may be presented for conversion ("Conversion Agent"). The Company shall also
appoint a bid calculation agent (the "Bid Calculation Agent") to act pursuant to
Article 13. The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Company may have one or more co-registrars, one or
more additional paying agents and one or more additional conversion agents. The
term Paying Agent includes any additional paying agent, including any named
pursuant to Section 4.05 hereof. The term Conversion Agent includes any
additional conversion agent, including any named pursuant to Section 4.05
hereof.

          The Company shall enter into an appropriate agency agreement with any
Registrar or co-registrar, Paying Agent, Conversion Agent or Bid Calculation
Agent (other than the Trustee). The agreement shall implement the provisions of
this Indenture that relate to such agent. The Company shall notify the Trustee
of the name and address of any such agent. If the

                                       12

<PAGE>

Company fails to maintain a Registrar, Paying Agent, Conversion Agent or Bid
Calculation Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07 hereof. The Company
or any Subsidiary or an Affiliate of either of them may act as Paying Agent,
Registrar, Conversion Agent or co-registrar. None of the Company or any
Subsidiary or any Affiliate of either of them may act as Bid Calculation Agent.

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

          SECTION 2.04   Paying Agent to Hold Money and Securities in Trust.
Except as otherwise provided herein, not later than 10:00 a.m., New York City
time, on each due date of payments in respect of any Security, the Company shall
deposit with the Paying Agent a sum of money (in immediately available funds if
deposited on the due date) or Common Stock sufficient to make such payments when
so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money and Common Stock held by the
Paying Agent for the making of payments in respect of the Securities and shall
notify the Trustee of any default by the Company in making any such payment. At
any time during the continuance of any such default, the Paying Agent shall,
upon the written request of the Trustee, forthwith pay to the Trustee all money
and Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate
of either of them acts as Paying Agent, it shall segregate the money and Common
Stock held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money and Common Stock
held by it to the Trustee and to account for any funds and Common Stock
disbursed by it. Upon doing so, the Paying Agent shall have no further liability
for the money or Common Stock.

          SECTION 2.05   Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall cause to be furnished to the Trustee at least
semiannually on April 29 and October 30 a listing of Securityholders dated
within 15 days of the date on which the list is furnished and at such other
times as the Trustee may request in writing a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of
Securityholders.

          SECTION 2.06   Transfer and Exchange. Subject to Section 2.12 hereof,

          (a)  Upon surrender for registration of transfer of any Security,
together with a written instrument of transfer satisfactory to the Registrar
duly executed by the Securityholder or such Securityholder's attorney duly
authorized in writing, at the office or agency of the Company designated as
Registrar or co-registrar pursuant to Section 2.03 hereof, the Company shall
execute, and the Trustee upon receipt of a Company Order shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denomination or denominations, of a like
aggregate Principal Amount at Maturity. The Company shall not charge a service
charge for any registration of transfer or exchange, but the Company or the
Trustee may require payment of a sum sufficient to pay all taxes, assessments or
other governmental charges that may be imposed in connection with the
registration of transfer

                                       13

<PAGE>

or exchange of the Securities from the Securityholder requesting such
registration of transfer or exchange.

          At the option of the Holder, Certificated Securities may be exchanged
for other Securities of any authorized denomination or denominations, of a like
aggregate Principal Amount at Maturity, upon surrender of the Securities to be
exchanged, together with a written instrument of transfer satisfactory to the
Registrar duly executed by the Securityholder or such Securityholder's attorney
duly authorized in writing, at such office or agency. Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee upon
receipt of a Company Order shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

          The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities in respect of which a Purchase Notice or Change in
Control Purchase Notice has been given and not withdrawn by the Holder thereof
in accordance with the terms of this Indenture (except, in the case of
Securities to be purchased in part, the portion thereof not to be purchased) or
any Securities for a period of 15 days before the mailing of a notice of
redemption of Securities to be redeemed.

          (b)  Notwithstanding any provision to the contrary herein, so long as
a Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, shall be made
only in accordance with Section 2.12 hereof and this Section 2.06(b). Transfers
of a Global Security shall be limited to transfers of such Global Security in
whole, or in part, to nominees of the Depositary or to a successor of the
Depositary or such successor's nominee.

          (c)  Successive registrations and registrations of transfers and
exchanges as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Securities.

          (d)  Any Registrar appointed pursuant to Section 2.03 hereof shall
provide to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon registration
of transfer or exchange of Securities.

          (e)  No Registrar shall be required to make registrations of transfer
or exchange of Securities during any periods designated in the text of the
Securities or in this Indenture as periods during which such registration of
transfers and exchanges need not be made.

          (f)  If Securities are issued upon the registration of transfer,
exchange or replacement of Securities subject to restrictions on transfer and
bearing the legends set forth on the form of Security attached hereto as
Exhibits A-1 and A-2 setting forth such restrictions (collectively, the
"Legend"), or if a request is made to remove the Legend on a Security, the
Securities so issued shall bear the Legend, or the Legend shall not be removed,
as the case may be, unless there is delivered to the Company and the Registrar
such satisfactory evidence, which shall include an Opinion of Counsel, as may be
reasonably required by the Company and the Registrar, that neither the Legend
nor the restrictions on transfer set forth therein are required to

                                       14

<PAGE>

ensure that transfers thereof comply with the provisions of Rule 144A or Rule
144 or that such Securities are not "restricted" within the meaning of Rule 144.
Upon (i) provision of such satisfactory evidence, or (ii) notification by the
Company to the Trustee and Registrar of the sale of such Security pursuant to a
registration statement that is effective at the time of such sale, the Trustee,
upon receipt of a Company Order, shall authenticate and deliver a Security that
does not bear the Legend. If the Legend is removed from the face of a Security
and the Security is subsequently held by an Affiliate of the Company, the
Company shall use reasonable efforts to reinstate the Legend.

          The Trustee and the Registrar shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any
transfer of any interest in any Security (including any transfers between or
among Depositary participants or beneficial owners of interests in any Global
Security) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements
hereof.

          SECTION 2.07   Replacement Securities. If (a) any mutilated Security
is surrendered to the Trustee, or (b) the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Security, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been
acquired by a protected purchaser within the meaning of Article 8 of the Uniform
Commercial Code (a "Protected Purchaser"), the Company shall execute and upon
receipt of a Company Order, the Trustee shall authenticate and deliver, in
exchange for any such mutilated Security or in lieu of any such destroyed, lost
or stolen Security, a new Security of like tenor and Principal Amount at
Maturity, bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, or is about to be purchased by the
Company pursuant to Article 3 hereof, the Company in its discretion may, instead
of issuing a new Security, pay or purchase such Security, as the case may be.

          Upon the issuance of any new Securities 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 and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          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 destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all benefits of this Indenture equally and proportionately with any
and all other Securities duly issued hereunder.

                                       15

<PAGE>

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

          SECTION 2.08   Outstanding Securities; Determinations of Holders'
Action. Securities outstanding at any time are all the Securities authenticated
by the Trustee, except for those cancelled by it, those paid pursuant to Section
2.10 hereof and delivered to it for cancellation and those described in this
Section 2.08 as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate thereof holds the Security; provided,
however, that in determining whether the Holders of the requisite Principal
Amount at Maturity of Securities have given or concurred in any request, demand,
authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the
Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, only Securities which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded. Subject to the foregoing,
only Securities outstanding at the time of such determination shall be
considered in any such determination (including, without limitation,
determinations pursuant to Articles 6 and 9).

          If a Security is replaced pursuant to Section 2.07 hereof, the
replaced Security ceases to be outstanding unless the Trustee and the Company
receive proof satisfactory to each of them that the replaced Security is held by
a Protected Purchaser unaware that such Security has been replaced, in which
case the replacement security shall be deemed not to be outstanding.

          If the Paying Agent holds, in accordance with this Indenture, on a
Redemption Date, or on the Business Day following the Purchase Date or a Change
in Control Purchase Date, or on Stated Maturity, money or securities, if
permitted hereunder, sufficient to pay Securities payable on that date, then
immediately after such Redemption Date, Purchase Date, Change in Control
Purchase Date or Stated Maturity, as the case may be, such Securities shall
cease to be outstanding and Original Issue Discount or any cash interest on such
Securities shall cease to accrue; provided, that if such Securities are to be
redeemed, notice of such redemption has been duly given pursuant to this
Indenture.

          If a Security is converted in accordance with Article 11, then from
and after the time of conversion on the Conversion Date, such Security shall
cease to be outstanding and Original Issue Discount or cash interest shall cease
to accrue on such Security.

          SECTION 2.09   Temporary Securities. Pending the preparation of
definitive Securities, the Company may execute, and upon a Company Order, the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as conclusively evidenced by their execution of such Securities.

                                       16

<PAGE>

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 2.03,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities the Company shall execute and upon Company Order the
Trustee shall authenticate and deliver in exchange therefor a like Principal
Amount at Maturity of definitive Securities of authorized denominations. Until
so exchanged the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities.

          SECTION 2.10   Cancellation. All Securities surrendered for payment,
purchase by the Company pursuant to Article 3 hereof, conversion, redemption or
registration of transfer or exchange shall, if surrendered to any person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee. The Company may not issue new
Securities to replace Securities it has paid or delivered to the Trustee for
cancellation or that any Holder has converted pursuant to Article 11 hereof. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee.

          SECTION 2.11   Persons Deemed Owners. Prior to due presentment of a
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of the Security or the payment of any Redemption Price, Purchase Price
or Change in Control Purchase Price in respect thereof or cash interest thereon,
for the purpose of conversion and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the Trustee nor any agent
of the Company or the Trustee shall be affected by notice to the contrary.

          SECTION 2.12   Global Securities.

          (a)  Notwithstanding any other provisions of this Indenture or the
Securities, (i) transfers of a Global Security, in whole or in part, shall be
made only in accordance with Sections 2.06 and 2.12(b)(i) hereof, (ii) transfer
of a beneficial interest in a Global Security for a Certificated Security shall
comply with Sections 2.06 and 2.12(b)(i) hereof, and (iii) transfers of a
Certificated Security shall comply with Sections 2.06 and 2.12(b)(ii) hereof and
transfer of a Certificated Security for a Beneficial Interest in a Global
Security shall comply with Sections 2.06 and 2.12(b)(iii) hereof.

          (b)  Transfer of Global Security. A Global Security may not be
transferred, in whole or in part, to any Person other than the Depositary or a
nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided that this Section 2.12(b) shall not prohibit any
transfer of a Security that is issued in exchange for a Global Security but is
not itself a Global Security. No transfer of a Security to any Person shall be

                                       17

<PAGE>

effective under this Indenture or the Securities unless and until such Security
has been registered in the name of such Person. Nothing in this Section 2.12(b)
shall prohibit or render ineffective any transfer of a beneficial interest in a
Global Security effected in accordance with the other provisions of this Section
2.12(b).

          (i)   Restrictions on Transfer of a Beneficial Interest in a Global
     Security for a Certificated Security. A beneficial interest in a Global
     Security may not be exchanged for a Certificated Security except upon
     satisfaction of the requirements set forth below. Upon receipt by the
     Trustee of a request for transfer of a beneficial interest in a Global
     Security in accordance with Applicable Procedures for a Certificated
     Security in the form satisfactory to the Trustee, together with:

                (A)  so long as the Securities are Restricted Securities,
          certification, in the form set forth in Exhibit B-1 attached hereto,
          and, if requested by the Company or the Registrar, certification in
          the form set forth in Exhibit B-2 attached hereto, that such
          beneficial interest in the Global Security is being transferred to an
          Institutional Accredited Investor that satisfies the definitions set
          forth in subparagraphs (a)(1), (2), (3) or (7) of Rule 501 under the
          Securities Act;

                (B)  written instructions to the Trustee to make, or direct the
          Registrar to make, an adjustment on its books and records with respect
          to such Global Security to reflect a decrease in the aggregate
          Principal Amount at Maturity of the Securities represented by the
          Global Security, such instructions to contain information regarding
          the Depositary account to be credited with such decrease; and

                (C)  if the Company or Registrar so requests, an Opinion of
          Counsel or other evidence reasonably satisfactory to them as to the
          compliance with the restrictions set forth in the Legend,

     then the Trustee shall cause, or direct the Registrar to cause, in
     accordance with the standing instructions and procedures existing between
     the Depositary and the Registrar, the aggregate Principal Amount at
     Maturity of Securities represented by the Global Security to be decreased
     by the aggregate Principal Amount at Maturity of the Certificated Security
     to be issued, shall authenticate and deliver such Certificated Security and
     shall debit or cause to be debited to the account of the Person specified
     in such instructions a beneficial interest in the Global Security equal to
     the Principal Amount at Maturity of the Certificated Security so issued.

          (ii)  Transfer and Exchange of Certificated Securities. When
     Certificated Securities are presented to the Registrar with a request:

                (x)  to register the transfer of such Certificated Securities;
                     or

                (y)  to exchange such Certificated Securities for an equal
                     Principal Amount at Maturity of Certificated Securities of
                     other authorized denominations,

                                       18

<PAGE>

     the Registrar shall register the transfer or make the exchange as requested
     if its reasonable requirements for such transaction are met; provided,
     however, that the Certificated Securities surrendered for registration of
     transfer or exchange:

                 (A)  shall be duly endorsed or accompanied by a written
          instrument of transfer in form reasonably satisfactory to the Company
          and the Registrar, duly executed by the Holder thereof or his attorney
          duly authorized in writing; and

                 (B)  so long as such Securities are Restricted Securities, such
          Securities are being transferred or exchanged pursuant to an effective
          registration statement under the Securities Act or, if being
          transferred pursuant to clause (1), (2) or (3) of this Section
          2.12(b)(ii)B, are accompanied by the additional information and
          documents specified in each such clause, as applicable:

                      (1)  if such Certificated Securities are being delivered
                           to the Registrar by a Holder for registration in the
                           name of such Holder, without transfer, a
                           certification from such Holder to that effect; or

                      (2)  if such Certificated Securities are being transferred
                           to the Company, a certification to that effect; or

                      (3)  if such Certificated Securities are being transferred
                           pursuant to an exemption from registration (1) a
                           certification to that effect (in the form set forth
                           in Exhibit B-1 and B-2 attached hereto, if
                           applicable) and (2) if the Company or Registrar so
                           requests, an opinion of counsel or other evidence
                           reasonably satisfactory to them as to the compliance
                           with the restrictions set forth in the Legend.

          (iii)  Restrictions on Transfer of a Certificated Security for a
     Beneficial Interest in a Global Security. A Certificated Security may not
     be exchanged for a beneficial interest in a Global Security except upon
     satisfaction of the requirements set forth below.

          Upon receipt by the Trustee of a Certificated Security, duly endorsed
          or accompanied by appropriate instruments of transfer, in form
          satisfactory to the Trustee, together with:

                 (A)  so long as the Securities are Restricted Securities,
          certification, in the form set forth in Exhibit B-1 attached hereto,
          that such Certificated Security is being transferred to a QIB in
          accordance with Rule 144A; and

                 (B)  written instructions directing the Trustee to make, or to
          direct the Registrar to make, an adjustment on its books and records
          with respect to such Global Security to reflect an increase in the
          aggregate Principal Amount at Maturity of the Securities represented
          by the Global Security, such instructions to contain information
          regarding the Depositary account to be credited with such increase;
          and

                                       19

<PAGE>

then the Trustee shall cancel such Certificated Security and cause, or direct
the Registrar to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Registrar, the aggregate
Principal Amount at Maturity of Securities represented by the Global Security to
be increased by the aggregate Principal Amount at Maturity of the Certificated
Security to be exchanged, and shall credit or cause to be credited to the
account of the Person specified in such instructions a beneficial interest in
the Global Security equal to the Principal Amount at Maturity of the
Certificated Security so cancelled. If no Global Securities are then
outstanding, the Company shall issue and the Trustee, upon receipt of a Company
Order, shall authenticate a new Global Security in the appropriate Principal
Amount at Maturity.

          (c)  Subject to the succeeding paragraph, every Security shall be
subject to the restrictions on transfer provided in the Legend including the
requirement of the delivery of an Opinion of Counsel, if so provided. Whenever
any Restricted Security is presented or surrendered for registration of transfer
or for exchange for a Security registered in a name other than that of the
Holder, such Security must be accompanied by a certificate in substantially the
form set forth in Exhibit B-1 attached hereto, dated the date of such surrender
and signed by the Holder of such Security, as to compliance with such
restrictions on transfer. The Registrar shall not be required to accept for such
registration of transfer or exchange any Security not so accompanied by a
properly completed certificate.

          (d)  The restrictions imposed by the Legend upon the transferability
of any Security shall cease and terminate when such Security has been sold
pursuant to an effective registration statement under the Securities Act or
transferred in compliance with Rule 144 or, if earlier, upon the expiration of
the holding period applicable to sales thereof under paragraph (k) of Rule 144.
Any Security as to which such restrictions on transfer shall have expired in
accordance with their terms or shall have terminated may, upon a surrender of
such Security for exchange to the Registrar in accordance with the provisions of
this Section 2.12 (accompanied, in the event that such restrictions on transfer
have terminated by reason of a transfer in compliance with Rule 144, by an
opinion of counsel having substantial experience in practice under the
Securities Act and otherwise reasonably acceptable to the Company, addressed to
the Company, the Trustee and the Registrar and in form acceptable to the
Company, to the effect that the transfer of such Security has been made in
compliance with Rule 144), be exchanged for a new Security, of like tenor and
aggregate Principal Amount at Maturity, which shall not bear the restrictive
Legend. The Company shall inform the Trustee of the effective date of any
registration statement registering the Securities under the Securities Act. The
Trustee and the Registrar shall not be liable for any action taken or omitted to
be taken by it in good faith in accordance with the aforementioned opinion of
counsel or registration statement.

          (e)  As used in the preceding two paragraphs of this Section 2.12, the
term "transfer" encompasses any sale, pledge, transfer, hypothecation or other
disposition of any Security.

          (f)  The provisions of clauses (i), (ii), (iii), (iv) and (v) of this
Section 2.12(f) shall apply only to Global Securities:

                                       20

<PAGE>

          (i)    Notwithstanding any other provisions of this Indenture or the
     Securities, except as provided in Section 2.12(b)(i) hereof, a Global
     Security shall not be exchanged in whole or in part for a Security
     registered in the name of any Person other than the Depositary or one or
     more nominees thereof, provided that a Global Security may be exchanged for
     Securities registered in the names of any person designated by the
     Depositary in the event that (A) the Depositary has notified the Company
     that it is unwilling or unable to continue as Depositary for such Global
     Security or such Depositary has ceased to be a "clearing agency" registered
     under the Exchange Act, and a successor Depositary is not appointed by the
     Company within 90 days; (B) the Company elects to discontinue use of the
     system of book-entry transfer through DTC (or any successor depositary); or
     (C) an Event of Default has occurred and is continuing with respect to the
     Securities. Any Global Security exchanged pursuant to clause (A) of this
     sub-section shall be so exchanged in whole and not in part, and any Global
     Security exchanged pursuant to clause (B) of this sub-section may be
     exchanged in whole or from time to time in part as directed by the
     Depositary. Any Security issued in exchange for a Global Security or any
     portion thereof shall be a Global Security; provided that any such Security
     so issued that is registered in the name of a person other than the
     Depositary or a nominee thereof shall not be a Global Security.

          (ii)   Securities issued in exchange for a Global Security or any
     portion thereof shall be issued in definitive, fully registered form,
     without interest coupons, shall have an aggregate Principal Amount at
     Maturity equal to that of such Global Security or portion thereof to be so
     exchanged, shall be registered in such names and be in such authorized
     denominations as the Depositary shall designate and shall bear the
     applicable legends provided for herein. Any Global Security to be exchanged
     in whole shall be surrendered by the Depositary to the Registrar. With
     regard to any Global Security to be exchanged in part, to give effect to
     any conversion, redemption or other disposition of such part or otherwise,
     either such Global Security shall be so surrendered for exchange or, if the
     Trustee is acting as custodian for the Depositary or its nominee with
     respect to such Global Security, the Principal Amount at Maturity thereof
     shall be reduced, by an amount equal to the portion thereof to be so
     exchanged, by means of an appropriate adjustment made on the records of the
     Trustee. Upon any such surrender or adjustment, the Trustee shall
     authenticate and deliver the Security issuable on such exchange to or upon
     the order of the Depositary or an authorized representative thereof.

          (iii)  Subject to the provisions of clause (v) of this Section
     2.12(f), the registered Holder may grant proxies and otherwise authorize
     any Person, including Agent Members (as defined below) and persons that may
     hold interests through Agent Members, to take any action which a holder is
     entitled to take under this Indenture or the Securities.

          (iv)   In the event of the occurrence of any of the events specified
     in clause (i) above, the Company will promptly make available to the
     Trustee a reasonable supply of Certificated Securities in definitive, fully
     registered form, without interest coupons.

          (v)    Neither any members of, or participants in, the Depositary
     (collectively, the "Agent Members") nor any other Persons on whose behalf
     Agent Members may act

                                       21

<PAGE>

     shall have any rights under this Indenture with respect to any Global
     Security registered in the name of the Depositary or any nominee thereof,
     or under any such Global Security, and the Depositary or such nominee, as
     the case may be, may be treated by the Company, the Trustee and any agent
     of the Company or the Trustee as the absolute owner and holder of such
     Global Security for all purposes whatsoever. Notwithstanding the foregoing,
     nothing herein shall prevent the Company, the Trustee or any agent of the
     Company or the Trustee from giving effect to any written certification,
     proxy or other authorization furnished by the Depositary or such nominee,
     as the case may be, or impair, as between the Depositary, its Agent Members
     and any other person on whose behalf an Agent Member may act, the operation
     of customary practices of such Persons governing the exercise of the rights
     of a holder of any Security.

          SECTION 2.13   CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the CUSIP numbers.

                                   ARTICLE 3
                            REDEMPTION AND PURCHASES

          SECTION 3.01   Right to Redeem; Notices to Trustee. The Company, at
its option, may redeem the Securities in accordance with the provisions of
paragraphs 6 and 8 of the Securities. Prior to May 14, 2007, the Company may not
redeem the Securities. Beginning on May 14, 2007, the Company may redeem the
Securities for cash in whole at any time, or in part from time to time. If the
Company elects to redeem Securities pursuant to paragraph 6 of the Securities,
it shall notify the Trustee in writing of the Redemption Date, the Principal
Amount at Maturity of Securities to be redeemed, the Redemption Price and the
amount of accrued and unpaid cash interest, if any, payable on the Redemption
Date.

          The Company shall give the notice to the Trustee provided for in this
Section 3.01 by a Company Order, at least 45 days before the Redemption Date
(unless a shorter notice shall be satisfactory to the Trustee). If fewer than
all the Securities are to be redeemed, the record date relating to such
redemption shall be selected by the Company and given to the Trustee, which
record date shall not be less than ten days after the date of notice to the
Trustee.

          SECTION 3.02   Selection of Securities to Be Redeemed. If less than
all the outstanding Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by any other method the Trustee
considers fair and appropriate (so long as such method is not prohibited by the
rules of any stock exchange on which the Securities are then listed). The
Trustee shall make the selection at least 30 days but not more than 60 days
before the Redemption Date from outstanding Securities not previously called for
redemption. The Trustee may select for redemption portions of the Principal
Amount at Maturity of Securities that have denominations larger than $1,000.

                                       22

<PAGE>

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

          If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as may be) to be the portion selected for redemption. Securities which have
been converted during a selection of Securities to be redeemed may be treated by
the Trustee as outstanding for the purpose of such selection.

          SECTION 3.03   Notice of Redemption. At least 30 days but not more
than 60 days before a Redemption Date, the Company shall mail a notice of
redemption by first-class mail, postage prepaid, to each Holder of Securities to
be redeemed.

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

          (a)  the Redemption Date;

          (b)  the Redemption Price, or if then not ascertainable, the manner of
     calculation thereof, and accrued and unpaid cash interest, if any, payable
     on the Redemption Date;

          (c)  the Conversion Rate;

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

          (e)  that Securities called for redemption may be converted at any
     time before the close of business on the second Business Day immediately
     preceding the Redemption Date, even if not otherwise convertible at such
     time;

          (f)  that Holders who want to convert Securities must satisfy the
     requirements set forth in paragraph 9 of the Securities;

          (g)  that Securities called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price and accrued and unpaid cash
     interest, if any;

          (h)  if fewer than all the outstanding Securities are to be redeemed,
     the certificate number and Principal Amounts at Maturity of the particular
     Securities to be redeemed;

          (i)  that, unless the Company defaults in making payment of such
     Redemption Price and any cash interest which is due and payable, Original
     Issue Discount or cash interest, including Contingent Cash Interest, will
     cease to accrue on and after the Redemption Date;

          (j)  the CUSIP number of the Securities; and

                                       23

<PAGE>

          (k)   any other information the Company desires, in its own
     discretion, to present.

          At the Company's request, the Trustee shall give the notice of
redemption to Holders in the Company's name and at the Company's expense,
provided that the Company makes such request at least five Business Days (unless
a shorter period shall be satisfactory to the Trustee) prior to the date such
notice of redemption must be mailed.

          SECTION 3.04   Effect of Notice of Redemption. Once notice of
redemption is given, Securities called for redemption become due and payable on
the Redemption Date and at the Redemption Price (together with accrued and
unpaid cash interest, if any, to but not including the date of redemption)
stated in the notice except for Securities which are converted in accordance
with the terms of this Indenture. Upon surrender to the Paying Agent, such
Securities shall be paid at the Redemption Price (together with accrued and
unpaid cash interest, if any, to but not including the date of redemption)
stated in the notice.

          SECTION 3.05   Deposit of Redemption Price. Prior to 10:00 a.m. New
York City time, on any Redemption Date, the Company shall deposit with the
Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of
them is the Paying Agent, shall segregate and hold in trust) money sufficient to
pay the Redemption Price of, and any accrued and unpaid interest to but not
including the date of redemption with respect to, all Securities to be redeemed
on that date other than Securities or portions of Securities called for
redemption which on or prior thereto have been delivered by the Company to the
Trustee for cancellation or have been converted. The Paying Agent shall as
promptly as practicable return to the Company any money not required for that
purpose because of conversion of Securities pursuant to Article 11 hereof. If
such money is then held by the Company in trust and is not required for such
purpose it shall be discharged from such trust.

          SECTION 3.06   Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate and deliver to the Holder a new Security in an authorized
denomination equal in Principal Amount at Maturity to the unredeemed portion of
the Security surrendered.

          SECTION 3.07   Conversion Arrangement on Call for Redemption. In
connection with any redemption of Securities, the Company may arrange for the
purchase and conversion of any Securities called for redemption by an agreement
with one or more investment banks or other purchasers to purchase such
Securities by paying to the Trustee in trust for the Securityholders, on or
prior to 10:00 a.m. New York City time on the Redemption Date, an amount that,
together with any amounts deposited with the Trustee by the Company for the
redemption of such Securities, is not less than the Redemption Price of, and any
accrued and unpaid interest with respect to, such Securities. Notwithstanding
anything to the contrary contained in this Article 3, the obligation of the
Company to pay the Redemption Prices of such Securities shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, any Securities not duly
surrendered for conversion by the Holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article 11) surrendered by such purchasers for conversion,

                                       24

<PAGE>

all as of immediately prior to the close of business on the Business Day prior
to the Redemption Date, subject to payment of the above amount as aforesaid. The
Trustee shall hold and pay to the Holders whose Securities are selected for
redemption any such amount paid to it for purchase and conversion in the same
manner as it would moneys deposited with it by the Company for the redemption of
Securities. Without the Trustee's prior written consent, no arrangement between
the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture,
and the Company agrees to indemnify the Trustee from, and hold it harmless
against, any loss, liability or expense arising out of or in connection with any
such arrangement for the purchase and conversion of any Securities between the
Company and such purchasers, including the costs and expenses incurred by the
Trustee in the defense of any claim or liability arising out of or in connection
with the exercise or performance of any of its powers, duties, responsibilities
or obligations under this Indenture.

          SECTION 3.08 Purchase of Securities at Option of the Holder.

          (a)  General. Securities shall be purchased by the Company pursuant to
paragraph 7 of the Securities as of May 14, 2007, 2012, 2017, 2022 and 2027
(each, a "Purchase Date"), at the purchase price of $425.00 per $1,000 of
Principal Amount at Maturity as of May 14, 2007, of $551.26 per $1,000 of
Principal Amount at Maturity as of May 14, 2012, of $639.76 per $1,000 of
Principal Amount at Maturity as of May 14, 2017, of $742.47 per $1,000 Principal
Amount at Maturity as of May 14, 2022, and of $861.67 per $1,000 Principal
Amount at Maturity as of May 14, 2027 in each case, plus accrued and unpaid cash
interest, if any, to the Purchase Date (each, a "Purchase Price", as
applicable), at the option of the Holder thereof, upon:

          (i)  delivery to the Paying Agent, by the Holder, of a written notice
     of purchase (a "Purchase Notice") at any time from the opening of business
     on the date that is 20 Business Days prior to a Purchase Date until the
     close of business on such Purchase Date stating:

               (A)  the certificate number of the Security which the Holder will
          deliver to be purchased,

               (B)  the portion of the Principal Amount at Maturity of the
          Security which the Holder will deliver to be purchased, which portion
          must be a Principal Amount at Maturity of $1,000 or an integral
          multiple thereof,

               (C)  that such Security shall be purchased as of the Purchase
          Date pursuant to the terms and conditions specified in paragraph 7 of
          the Securities and in this Indenture, and

               (D)  in the event the Company elects, pursuant to Section 3.08(b)
          hereof, to pay the Purchase Price to be paid as of such Purchase Date,
          in whole or in part, in shares of Common Stock but such portion of the
          Purchase Price shall ultimately be payable to such Holder entirely in
          cash because any of the conditions to payment of the Purchase Price in
          Common Stock is not satisfied

                                       25

<PAGE>

          prior to the close of business on such Purchase Date, as set forth in
          Section 3.08(d) hereof, whether such Holder elects (1) to withdraw
          such Purchase Notice as to some or all of the Securities to which such
          Purchase Notice relates (stating the Principal Amount at Maturity and
          certificate numbers of the Securities as to which such withdrawal
          shall relate), or (2) to receive cash in respect of the entire
          Purchase Price for all Securities (or portions thereof) to which such
          Purchase Notice relates; and

          (ii)   delivery of such Security to the Paying Agent prior to, on or
     after the Purchase Date (together with all necessary endorsements) at the
     offices of the Paying Agent, such delivery being a condition to receipt by
     the Holder of the Purchase Price therefor; provided, however, that such
     Purchase Price shall be so paid pursuant to this Section 3.08 only if the
     Security so delivered to the Paying Agent shall conform in all respects to
     the description thereof in the related Purchase Notice, as determined by
     the Company.

          If a Holder, in such Holder's Purchase Notice and in any written
notice of withdrawal delivered by such Holder pursuant to the terms of Section
3.10 hereof, fails to indicate such Holder's choice with respect to the election
set forth in clause (D) of Section 3.08(a)(i) hereof, such Holder shall be
deemed to have elected to receive cash in respect of the Purchase Price for all
Securities subject to such Purchase Notice in the circumstances set forth in
such clause (D).

          The Company shall purchase from the Holder thereof, pursuant to this
Section 3.08, a portion of a Security if the Principal Amount at Maturity of
such portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

          Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.08 shall be consummated by the delivery of the consideration to
be received by the Holder (together with accrued and unpaid cash interest, if
any) promptly following the later of the Purchase Date and the time of delivery
of the Security.

          Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Purchase Notice contemplated by this Section 3.08(a)
shall have the right to withdraw such Purchase Notice at any time prior to the
close of business on the business day prior to the Purchase Date by delivery of
a written notice of withdrawal to the Paying Agent in accordance with Section
3.10 hereof.

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

          (b)    Company's Right to Elect Manner of Payment of Purchase Price.
The Securities to be purchased pursuant to Section 3.08(a) hereof may be paid
for, at the election of the Company, in U.S. legal tender ("cash") or Common
Stock, or in any combination of cash and Common Stock, subject to the conditions
set forth in Sections 3.08(c) and (d) hereof. The Company shall designate, in
the Company Notice delivered pursuant to Section 3.08(e) hereof,

                                       26

<PAGE>

whether the Company will purchase the Securities for cash or Common Stock, or,
if a combination thereof, the percentages or amounts of the Purchase Price of
Securities in respect of which it will pay in cash or Common Stock; provided
that the Company will pay cash for fractional interests in Common Stock. For
purposes of determining the existence of potential fractional interests, all
Securities subject to purchase by the Company held by a Holder shall be
considered together (no matter how many separate certificates are to be
presented). Each Holder whose Securities are purchased pursuant to this Section
3.08 shall receive the same percentage of cash or Common Stock in payment of the
Purchase Price for such Securities, except (i) as provided in Section 3.08(d)
hereof with regard to the payment of cash in lieu of fractional shares of Common
Stock and (ii) in the event that the Company is unable to purchase the
Securities of a Holder or Holders for Common Stock because any necessary
qualifications or registrations of the Common Stock under applicable state
securities laws cannot be obtained, the Company may purchase the Securities of
such Holder or Holders for cash. The Company may not change its election with
respect to the consideration (or components or percentages of components
thereof) to be paid once the Company has given its Company Notice to
Securityholders except pursuant to this Section 3.08(b) or pursuant to Section
3.08(d) hereof in the event of a failure to satisfy, prior to the close of
business on the Purchase Date, any condition to the payment of the Purchase
Price, in whole or in part, in Common Stock.

          At least three Business Days before the Company Notice Date, the
Company shall deliver an Officers' Certificate to the Trustee specifying:

          (i)   the manner of payment selected by the Company,

          (ii)  the information required by Section 3.08(e) hereof,

          (iii) if the Company elects to pay the Purchase Price, or a specified
     percentage thereof, in Common Stock, that the conditions to such manner of
     payment set forth in Section 3.08(d) have been or will be complied with,
     and

          (iv)  whether the Company desires the Trustee to give the Company
     Notice required by Section 3.08(e) hereof.

          (c)   Purchase with Cash. On each Purchase Date, at the option of the
Company, the Purchase Price of Securities in respect of which a Purchase Notice
pursuant to Section 3.08(a) hereof has been given, or a specified percentage
thereof, may be paid by the Company with cash equal to the aggregate Purchase
Price of such Securities. If the Company elects to purchase Securities with
cash, the Company Notice, as provided in Section 3.08(e) hereof, shall be sent
to Holders (and to beneficial owners as required by applicable law) not less
than 20 Business Days prior to such Purchase Date (the "Company Notice Date").

          (d)   Payment by Issuance of Common Stock. On each Purchase Date, at
the option of the Company, the Purchase Price of Securities in respect of which
a Purchase Notice pursuant to Section 3.08(a) hereof has been given, or a
specified percentage thereof, may be paid by the Company by the issuance of a
number of shares of Common Stock equal to the quotient obtained by dividing (i)
the amount of cash to which the Securityholders would have been entitled had the
Company elected to pay all or such specified percentage, as the case may be, of

                                       27

<PAGE>

the Purchase Price of such Securities in cash by (ii) the Market Price of a
share of Common Stock, subject to the next succeeding paragraph.

          The Company will not issue a fractional share of Common Stock in
payment of the Purchase Price. Instead the Company will pay cash for the current
market value of the fractional share. The current market value of a fraction of
a share shall be determined by multiplying the Market Price by such fraction and
rounding the product to the nearest whole cent. It is understood that if a
Holder elects to have more than one Security purchased, the number of shares of
Common Stock shall be based on the aggregate amount of Securities to be
purchased.

          Upon a payment by Common Stock pursuant to the terms hereof, that
portion of accrued Original Issue Discount or cash interest attributable to the
period from the Issue Date to the Purchase Date with respect to the purchased
Security shall not be cancelled, extinguished or forfeited but rather shall be
deemed paid in full to the Holder through the delivery of the Common Stock in
exchange for the Security being purchased pursuant to the terms hereof, and the
fair market value of such Common Stock (together with any cash payments in lieu
of fractional shares of Common Stock) shall be treated as issued, to the extent
thereof, first in exchange for the accrued Original Issue Discount or cash
interest through the Purchase Date, and the balance, if any, of the fair market
value of such shares of Common Stock shall be treated as issued in exchange for
the Issue Price of the Security being purchased pursuant to the provisions
hereof. If the Company elects to purchase the Securities by the issuance of
shares of Common Stock, the Company Notice, as provided in Section 3.08(e)
hereof, shall be sent to the Holders (and to beneficial owners as required by
applicable law) not later than the Company Notice Date.

          The Company's right to exercise its election to purchase the
Securities pursuant to this Section 3.08 through the issuance of shares of
Common Stock shall be conditioned upon:

          (i)    the Company's not having given its Company Notice of an
     election to pay entirely in cash and its giving of timely Company Notice of
     election to purchase all or a specified percentage of the Securities with
     Common Stock as provided herein;

          (ii)   the shares of Common Stock having been admitted for listing or
     admitted for listing subject to notice of issuance on the principal United
     States securities exchange on which the Common Stock is then listed or, if
     the Common Stock is not then listed on a national or regional securities
     exchange, as quoted on the National Association of Securities Dealers
     Automated Quotation System;

          (iii)  the registration of the shares of Common Stock to be issued in
     respect of the payment of the Purchase Price under the Securities Act of
     1933, as amended (the "Securities Act"), or the Securities Exchange Act of
     1934, as amended (the "Exchange Act"), in each case, if required;

          (iv)   any necessary qualification or registration under applicable
     state securities laws or the availability of an exemption from such
     qualification and registration; and

          (v)    the receipt by the Trustee of an Officers' Certificate and an
     Opinion of Counsel each stating that (A) the terms of the issuance of the
     Common Stock are in

                                       28

<PAGE>

     conformity with this Indenture and (B) the shares of Common Stock to be
     issued by the Company in payment of the Purchase Price in respect of
     Securities have been duly authorized and, when issued and delivered
     pursuant to the terms of this Indenture in payment of the Purchase Price in
     respect of the Securities, will be validly issued, fully paid and
     non-assessable and, to the best of such counsel's knowledge, free from
     preemptive rights under law or material contracts, and, in the case of such
     Officers' Certificate, stating that conditions (i), (ii), (iii) and (iv)
     above and the condition set forth in the second succeeding sentence have
     been satisfied and, in the case of such Opinion of Counsel, stating that
     conditions (ii) and (iii) above have been satisfied.

          Such Officers' Certificate shall also set forth the number of shares
of Common Stock to be issued for each $1,000 Principal Amount at Maturity of
Securities and the Sale Price of a share of Common Stock on each Trading Day
during the period for which the Market Price is calculated. The Company may pay
the Purchase Price (or any portion thereof) in Common Stock only if the
information necessary to calculate the Market Price is published in a daily
newspaper of national circulation. If the foregoing conditions are not satisfied
with respect to a Holder or Holders prior to the close of business on the
Purchase Date and the Company has elected to purchase the Securities pursuant to
this Section 3.08 through the issuance of shares of Common Stock, the Company
shall pay the entire Purchase Price of the Securities of such Holder or Holders
in cash.

          The "Market Price" of the Common Stock means the average of the Sale
Prices of the Common Stock for the five Trading Day period ending on the third
Business Day (if the third Business Day prior to the applicable Purchase Date is
a Trading Day or, if not, then on the last Trading Day prior to such Business
Day) prior to the applicable Purchase Date, appropriately adjusted to take into
account the occurrence, during the period commencing on the first of such
Trading Days during such five Trading Day period and ending on such Purchase
Date, of any event described in Section 11.06, 11.07 or 11.08 hereof; subject,
however, to the conditions set forth in Sections 11.09 and 11.10 hereof.

          (e)   Notice of Election. The Company's notice of election to purchase
with cash or Common Stock or any combination thereof shall be sent to the
Holders (and to beneficial owners as required by applicable law) in the manner
provided in Section 14.02 hereof at the time specified in Section 3.08(c) or (d)
hereof, as applicable (the "Company Notice"). Such Company Notice shall state
the manner of payment elected and shall contain the following information:

          In the event the Company has elected to pay the Purchase Price (or a
specified percentage thereof) with Common Stock, the Company Notice shall:

          (i)   state that each Holder will receive Common Stock with a Market
     Price determined as of a specified date prior to the Purchase Date equal to
     such specified percentage of the Purchase Price of the Securities held by
     such Holder (except any cash amount to be paid in lieu of fractional
     shares);

          (ii)  set forth the method of calculating the Market Price of the
                Common Stock; and

                                       29

<PAGE>

          (iii) state that because the Market Price of Common Stock will be
     determined prior to the Purchase Date, Holders will bear the market risk
     with respect to the value of the Common Stock to be received from the date
     such Market Price is determined to the Purchase Date.

          In any case, each Company Notice shall include a form of Purchase
Notice to be completed by a Securityholder and shall state:

          (i)    the Purchase Price, the Conversion Rate and accrued and unpaid
     cash interest, including Contingent Cash Interest, if any, that will be
     accrued and payable with respect to the Securities as of the Purchase Date;

          (ii)   whether the Company will pay the Purchase Price in cash or in
     Common Stock or any combination thereof, specifying the percentage of each;

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

          (iv)   that Securities as to which a Purchase Notice has been given
     may be converted pursuant to Article 11 hereof only if the applicable
     Purchase Notice has been withdrawn in accordance with the terms of this
     Indenture;

          (v)    that Securities must be surrendered to the Paying Agent to
     collect payment of the Purchase Price and interest, if any;

          (vi)   that the Purchase Price for any Security as to which a Purchase
     Notice has been given and not withdrawn, together with any cash interest
     payable with respect thereto, will be paid promptly following the later of
     the Purchase Date and the time of surrender of such Security as described
     in (v);

          (vii)  the procedures the Holder must follow to exercise rights under
     this Section 3.08 and a brief description of those rights;

          (viii) briefly, the conversion rights of the Securities and that
     Holders who want to convert Securities must satisfy the requirements set
     forth in paragraph 9 of the Securities;

          (ix)   the procedures for withdrawing a Purchase Notice (including,
     without limitation, for a conditional withdrawal pursuant to the terms of
     Section 3.08(a)(i)(D) or Section 3.10 hereof);

          (x)    that, unless the Company defaults in making payment of such
     Purchase Price and cash interest, if any, Original Issue Discount and cash
     interest, including Contingent Cash Interest, if any, on Securities
     surrendered for purchase will cease to accrue on and after the Purchase
     Date; and

          (xi)   the CUSIP number of the Securities.

                                       30

<PAGE>

          At the Company's request, the Trustee shall give such Company Notice
in the Company's name and at the Company's expense; provided, however, that, in
all cases, the text of such Company Notice shall be prepared by the Company.

          Upon determination of the actual number of shares of Common Stock to
be issued for each $1,000 Principal Amount at Maturity of Securities, the
Company will issue a press release and publish such determination on the
Company's web site on the World Wide Web.

          (f)  Covenants of the Company. All shares of Common Stock delivered
upon purchase of the Securities shall be newly issued shares or treasury shares,
shall be duly authorized, validly issued, fully paid and nonassessable and shall
be free from preemptive rights and free of any lien or adverse claim created by
the Company.

          The Company shall use its reasonable efforts to list or cause to have
quoted any shares of Common Stock to be issued to purchase Securities on the
principal United States securities exchange or over-the-counter or other
domestic market on which any other shares of the Common Stock are then listed or
quoted. The Company will promptly inform the Trustee in writing of any such
listing.

          (g)  Procedure upon Purchase. The Company shall deposit cash (in
respect of a cash purchase under Section 3.08(c) hereof or for fractional
interests as applicable) or shares of Common Stock, or a combination thereof, as
applicable, at the time and in the manner as provided in Section 3.11 hereof,
sufficient to pay the aggregate Purchase Price of, and any accrued and unpaid
interest with respect to all Securities to be purchased pursuant to this Section
3.08. As soon as practicable after the Purchase Date, the Company shall deliver
to each Holder entitled to receive Common Stock through the Paying Agent, a
certificate for the number of full shares of Common Stock issuable in payment of
the Purchase Price and cash in lieu of any fractional interests. The person in
whose name the certificate for Common Stock is registered shall be treated as a
holder of record of shares of Common Stock on the Business Day following the
Purchase Date. Subject to Section 3.08(d) hereof, no payment or adjustment will
be made for dividends on the Common Stock the record date for which occurred on
or prior to the Purchase Date.

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

          SECTION 3.09   Purchase of Securities at Option of the Holder upon

indirectly through one or more intermediaries, of more than 50% of the voting

     at the time of such notice, the amount of interest, if any, that will be

     Control Purchase Date;

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

                                       32

          (vi)   the Conversion Rate and any adjustments thereto resulting from
     the Change in Control;

          (vii)  that Securities as to which a Change in Control Purchase Notice
     has been given may be converted pursuant to Article 11 hereof only if the
     Change in Control Purchase Notice has been withdrawn in accordance with the
     terms of this Indenture;

          (viii) that Securities must be surrendered to the Paying Agent to
     collect payment of the Change in Control Purchase Price and accrued and
     unpaid cash interest, if any;

          (ix)   that the Change in Control Purchase Price for any Security as
     to which a Change in Control Purchase Notice has been duly given and not
     withdrawn, together with any accrued interest payable with respect thereto,
     will be paid promptly following the later of the Change in Control Purchase
     Date and the time of surrender of such Security as described in Section
     3.09(b)(viii) hereof;

          (x)    briefly, the procedures the Holder must follow to exercise
     rights under this Section 3.09;

          (xi)   briefly, the conversion rights of the Securities;

          (xii)  the procedures for withdrawing a Change in Control Purchase
     Notice;

          (xiii) that, unless the Company defaults in making payment of such
     Change in Control Purchase Price and cash interest, if any on Securities
     surrendered for purchase, Original Issue Discount and any cash interest,
     including Contingent Cash Interest, on Securities surrendered for purchase
     will cease to accrue on and after the Change in Control Purchase Date; and

          (xiv)  the CUSIP number of the Securities.

          (c)    A Holder may exercise its rights specified in Section 3.09(a)
hereof upon delivery of a written notice of purchase (a "Change in Control
Purchase Notice") to the Paying Agent at any time prior to the close of business
on the Business Day prior to the Change in Control Purchase Date, stating:

          (i)    the certificate number or numbers of the Security or Securities
     which the Holder will deliver to be purchased;

          (ii)   the portion of the Principal Amount at Maturity of the Security
     which the Holder will deliver to be purchased, which portion must be $1,000
     or an integral multiple thereof; and

          (iii)  that such Security shall be purchased pursuant to the terms and
     conditions specified in paragraph 7 of the Securities.

          The delivery of such Security to the Paying Agent at any time after
the delivery of the Change in Control Purchase Notice (together with all
necessary endorsements) at the offices

                                       33

<PAGE>

of the Paying Agent shall be a condition to the receipt by the Holder of the
Change in Control Purchase Price therefor; provided, however, that such Change
in Control Purchase Price shall be so paid pursuant to this Section 3.09 only if
the Security so delivered to the Paying Agent shall conform in all respects to
the description thereof set forth in the related Change in Control Purchase
Notice.

          The Company shall purchase from the Holder thereof, pursuant to this
Section 3.09, a portion of a Security if the Principal Amount at Maturity of
such portion is $1,000 or an integral multiple of $1,000. Provisions of this
Indenture that apply to the purchase of all of a Security also apply to the
purchase of such portion of such Security.

          Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.09 shall be consummated by the delivery of the consideration to
be received by the Holder (together with accrued and unpaid interest, if any)
promptly following the later of the Change in Control Purchase Date and the time
of delivery of the Security to the Paying Agent in accordance with this Section
3.09.

          Notwithstanding anything herein to the contrary, any Holder delivering
to the Paying Agent the Change in Control Purchase Notice contemplated by this
Section 3.09(c) shall have the right to withdraw such Change in Control Purchase
Notice at any time prior to the close of business on the Business Day prior to
the Change in Control Purchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 3.10 hereof.

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

          The Company shall not be required to comply with this Section 3.09 if
a third party mails a written notice of Change in Control in the manner, at the
times and otherwise in compliance with this Section 3.09 and repurchases all
Securities for which a Change in Control Purchase Notice shall be delivered and
not withdrawn.

Notice. Upon receipt by the Paying Agent of the Purchase Notice or Change in
Control Purchase Notice specified in Section 3.08(a) or Section 3.09(c) hereof,
as applicable, the Holder of the Security in respect of which such Purchase
Notice or Change in Control Purchase Notice, as the case may be, was given shall
(unless such Purchase Notice or Change in Control Purchase Notice is withdrawn
as specified in the following two paragraphs) thereafter be entitled to receive
solely the Purchase Price or Change in Control Purchase Price, as the case may
be, and any accrued and unpaid interest, with respect to such Security. Such
Purchase Price or Change in Control Purchase Price which price reflects the
Issue Price plus accrued Original Issue Discount and accrued and unpaid cash
interest, including Contingent Cash Interest, if any, shall be paid to such
Holder, subject to receipt of funds and/or securities by the Paying Agent,
promptly following the later of (x) the Purchase Date or the Change in Control
Purchase Date, as the case may be, with respect to such Security (provided the
conditions in Section 3.08(a) or Section 3.09(c) hereof, as applicable, have
been satisfied) and (y) the time of delivery of such Security to the Paying
Agent by the Holder thereof in the manner required by Section 3.08(a) or Section
3.09(c) hereof, as applicable. Securities in respect of which a Purchase Notice
or Change in Control Purchase

                                       34

<PAGE>

Notice, as the case may be, has been given by the Holder thereof may not be
converted pursuant to Article 11 hereof on or after the date of the delivery of
such Purchase Notice or Change in Control Purchase Notice, as the case may be,
unless such Purchase Notice or Change in Control Purchase Notice, as the case
may be, has first been validly withdrawn as specified in the following two
paragraphs.

          A Purchase Notice or Change in Control Purchase Notice, as the case
may be, may be withdrawn by means of a written notice of withdrawal delivered to
the office of the Paying Agent at any time prior to the close of business on the
Business Day prior to the Purchase Date or the Change in Control Purchase Date,
as the case may be, specifying:

          (a)   the certificate number or numbers of the Security or Securities
     in respect of which such notice of withdrawal is being submitted,

          (b)   the Principal Amount at Maturity of the Security or Securities
     with respect to which such notice of withdrawal is being submitted, and

          (c)   the Principal Amount at Maturity, if any, of such Security which
     remains subject to the original Purchase Notice or Change in Control
     Purchase Notice, as the case may be, and which has been or will be
     delivered for purchase by the Company.

          A written notice of withdrawal of a Purchase Notice may be in the form
set forth in the preceding paragraph or may be in the form of a conditional
withdrawal contained in a Purchase Notice pursuant to the terms of Section
3.08(a)(i)(D) hereof.

          There shall be no purchase of any Securities pursuant to Section 3.08
hereof (other than through the issuance of Common Stock in payment of the
Purchase Price, including cash in lieu of fractional shares) or 3.09 hereof if
there has occurred (prior to, on or after, as the case may be, the giving, by
the Holders of such Securities, of the required Purchase Notice or Change in
Control Purchase Notice, as the case may be) and is continuing an Event of
Default (other than a default in the payment of the Purchase Price or Change in
Control Purchase Price, as the case may be, and any accrued and unpaid cash
interest with respect to such Securities). The Paying Agent will promptly return
to the respective Holders thereof any Securities (x) with respect to which a
Purchase Notice or Change in Control Purchase Notice, as the case may be, has
been withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of an Event of Default (other than a default in the payment of the
Purchase Price or Change in Control Purchase Price, as the case may be, and any
accrued and unpaid cash interest with respect to such Securities) in which case,
upon such return, the Purchase Notice or Change in Control Purchase Notice with
respect thereto shall be deemed to have been withdrawn.

          SECTION 3.11   Deposit of Purchase Price or Change in Control Purchase
Price. Prior to 10:00 a.m., New York City time, on the Business Day following
the Purchase Date or the Change in Control Purchase Date, as the case may be,
the Company shall deposit with the Trustee or with the Paying Agent (or, if the
Company or a Subsidiary or an Affiliate of either of them is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 2.04
hereof) an amount of money (in immediately available funds if deposited on such
Business Day) or Common Stock, if permitted hereunder, sufficient to pay the
aggregate

                                       35

<PAGE>

Purchase Price or Change in Control Purchase Price, as the case may be, of, and
any accrued and unpaid cash interest with respect to, all the Securities or
portions thereof which are to be purchased as of the Purchase Date or Change in
Control Purchase Date, as the case may be.

          SECTION 3.12   Securities Purchased in Part. Any Security which is to
be purchased only in part shall be surrendered at the office of the Paying Agent
(with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge,
a new Security or Securities, of any authorized denomination as requested by
such Holder in aggregate Principal Amount at Maturity equal to, and in exchange
for, the portion of the Principal Amount at Maturity of the Security so
surrendered which is not purchased.

          SECTION 3.13   Repayment to the Company. The Trustee and the Paying
Agent shall promptly return to the Company any cash or shares of Common Stock
that remain unclaimed as provided in paragraph 15 of the Securities, together
with interest or dividends, if any, thereon (subject to the provisions of
Section 7.01(f) hereof), held by them for the payment of the Purchase Price or
Change in Control Purchase Price, as the case may be, or contingent interest, if
any; provided, however, that to the extent that the aggregate amount of cash or
shares of Common Stock deposited by the Company pursuant to Section 3.11 hereof
exceeds the aggregate Purchase Price or Change in Control Purchase Price, as the
case may be, of, and the accrued and unpaid contingent interest with respect to,
the Securities or portions thereof which the Company is obligated to purchase as
of the Purchase Date or Change in Control Purchase Date, as the case may be,
whether as a result of withdrawal or otherwise, then promptly after the Business
Day following the Purchase Date or Change in Control Purchase Date, as the case
may be, the Trustee shall return any such excess to the Company together with
interest or dividends, if any, thereon (subject to the provisions of Section
7.01(f) hereof).

                                    ARTICLE 4
                                    COVENANTS

          SECTION 4.01   Payment of Securities. The Company shall promptly make
all payments in respect of the Securities on the dates and in the manner
provided in the Securities or pursuant to this Indenture. Any amounts to be
given to the Trustee or Paying Agent, shall be deposited with the Trustee or
Paying Agent by 10:00 a.m., New York City time, by the Company. Principal Amount
at Maturity, Restated Principal Amount, Issue Price plus accrued Original Issue
Discount, Redemption Price, Purchase Price, Change in Control Purchase Price,
and cash interest shall be considered paid on the applicable date due if on such
date (or, in the case of a Purchase Price or Change in Control Purchase Price,
on the Business Day following the applicable Purchase Date or Change in Control
Purchase Date, as the case may be) the Trustee or the Paying Agent holds, in
accordance with this Indenture, money or securities, if permitted hereunder,
sufficient to pay all such amounts then due.

          The Company shall, to the extent permitted by law, pay cash interest
on overdue amounts at the rate per annum set forth in paragraph 1 of the
Securities, compounded semiannually, which interest shall accrue from the date
such overdue amount was originally due

                                       36

<PAGE>

to the date payment of such amount, including interest thereon, has been made or
duly provided for. All such interest shall be payable on demand. The accrual of
such interest on overdue amounts shall be in lieu of, and not in addition to,
the continued accrual of Original Issue Discount.

          SECTION 4.02  SEC and Other Reports. The Company shall deliver to the
Trustee, within 30 days after it files such annual and quarterly reports,
information, documents and other reports with the SEC, copies of its annual
report and of the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act. The Company also shall comply with the
provisions of TIA Section 314(a), provided that no report required thereby to be
filed with the SEC need be so filed unless this Indenture is qualified under the
TIA. Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of the same shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

          SECTION 4.03  Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company
(beginning with the fiscal year ending on December 31, 2002) an Officers'
Certificate, stating whether or not to the knowledge of the signers thereof the
Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

          SECTION 4.04  Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out the
purposes of this Indenture.

          SECTION 4.05  Maintenance of Office or Agency. The Company will
maintain in the Borough of Manhattan, The City of New York, an office or agency
of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities
may be presented or surrendered for payment, where Securities may be surrendered
for registration of transfer, exchange, purchase, redemption or conversion and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The office of the Trustee, located at JPMorgan
Chase Bank, 450 W. 33rd Street, 15th Floor, New York, New York 10001 Attention:
Institutional Trust Services, shall initially be such office or agency for all
of the aforesaid purposes. The Company shall give prompt written notice to the
Trustee of the location, and of any change in the location, of any such office
or agency (other than a change in the location of the office of the Trustee). If
at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 14.02 hereof.

                                       37

<PAGE>

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

          SECTION 4.06  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 or any beneficial holder of Securities or shares of Common
Stock which are restricted securities issued upon conversion thereof, the
Company will promptly furnish or cause to be furnished Rule 144A Information (as
defined below) to such Holder or any beneficial holder of Securities or holder
of shares of Common Stock issued upon conversion of Securities, or to a
prospective purchaser of any such security designated by any such holder, as the
case may be, to the extent required to permit compliance by such Holder or
holder with Rule 144A under the Securities Act in connection with the resale of
any such security. "Rule 144A Information" shall be such information as is
specified pursuant to Rule 144A(d)(4) under the Securities Act.

          SECTION 4.07  Covenant to Comply With Securities Laws Upon Purchase of
Securities. In connection with any offer to purchase or purchase of Securities
under Section 3.08 or 3.09 hereof (provided that such offer or purchase
constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as
used herein, includes any successor provision thereto) under the Exchange Act at
the time of such offer or purchase), the Company shall to the extent applicable
(a) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act, (b) file the
related Schedule TO (or any successor schedule, form or report) under the
Exchange Act, and (c) otherwise comply with all Federal and state securities
laws so as to permit the rights and obligations under Sections 3.08 and 3.09
hereof to be exercised in the time and in the manner specified in Sections 3.08
and 3.09 hereof.

          SECTION 4.08  Waiver of Compliance. The Company may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 4.01 to 4.07, inclusive, if before the time for such compliance the
Holders of a majority in aggregate Principal Amount at Maturity of the
Securities at the time outstanding shall notify the Company that they elect to
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 in respect of any such covenant or condition shall remain in full
force and effect.

                                   ARTICLE 5
                              SUCCESSOR CORPORATION

          SECTION 5.01  When Company May Merge or Transfer Assets. The Company
shall not consolidate with or merge with or into any other person or convey,
transfer or lease all or substantially all of its properties and assets to any
person, nor will the Company permit any Subsidiary to enter into any such
transaction or series of transactions if such transaction or series of
transactions, in the aggregate, would result in a sale, assignment, transfer,

                                       38

<PAGE>

lease or other disposition of all or substantially all of the properties and
assets of the Company and its Subsidiaries on a consolidated basis to any other
person or persons, unless:

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

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

          (c)  the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture,
comply with this Article 5 and that all conditions precedent herein provided for
relating to such transaction have been satisfied.

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

          The successor person formed by such consolidation or into which the
Company or the applicable Subsidiary is merged or the successor person to which
such conveyance, transfer or lease is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company or the applicable
Subsidiary under this Indenture with the same effect as if such successor had
been named as the Company or the applicable Subsidiary herein; and thereafter,
except in the case of a lease and any obligations the Company or the applicable
Subsidiary may have under a supplemental indenture pursuant to Section 11.14
hereof, the Company or the applicable Subsidiary shall be discharged from all
obligations and covenants under this Indenture and the Securities. Subject to
Section 9.06 hereof, the Company, the applicable Subsidiary, the Trustee and the
successor person shall enter into a supplemental indenture to evidence the
succession and substitution of such successor person and such discharge and
release of the Company and the applicable Subsidiary.

                              DEFAULTS AND REMEDIES

        SECTION 6.01  Events of Default. An "Event of Default" occurs if:

          (a)   the Company defaults in payment of any interest, including any
     Contingent Cash Interest, when due under the Securities and such default
     continues for 30 days;

          (b)   the Company defaults in the payment of the Principal Amount at
     Maturity (or, if the Securities have been converted to semiannual coupon
     notes following a Tax Event pursuant to Section 10.01 of the Indenture, the
     Restated Principal Amount), Issue Price plus accrued Original Issue
     Discount and any cash interest, including any Contingent Cash Interest,
     Redemption Price, Purchase Price or Change in Control Purchase Price on any
     Security when the same becomes due and payable at its Stated Maturity, upon
     redemption, upon declaration, when due for purchase by the Company or
     otherwise;

          (c)   the Company fails to comply with any of its agreements in the
     Security or this Indenture (other than those referred to in clauses (a) and
     (b) above) and such failure continues for 60 days after receipt by the
     Company of a Notice of Default;

          (d)   default under any Debt, whether such Debt now exists or is
     created later, which default results in such Debt becoming or being
     declared due and payable prior to the date on which it would otherwise have
     become due and payable, and the principal amount of all Debt so
     accelerated, together with all Debt due and payable but not paid prior to
     the end of any grace period, is $10,000,000 or more, and such acceleration
     has not been rescinded or annulled within a period of 10 days after receipt
     by the Company of a Notice of Default from the Trustee; provided, however,
     that if any such default shall be cured, waived, rescinded or annulled,
     then the Event of Default by reason thereof shall be deemed not to have
     occurred;

          (e)   the Company pursuant to or under or within the meaning of any
     Bankruptcy Law:

          (ii)  commences a voluntary case or proceeding;

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

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

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

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

                                       40

<PAGE>

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

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

          (i)   is for relief against the Company in an involuntary case or
                proceeding, or adjudicates the Company insolvent or bankrupt;

          (ii)  appoints a Custodian of the Company or for any substantial part
                of its property; or

          (iii) orders the winding up or liquidation of the Company;

          and such order or decree remains unstayed and in effect for 60 days.

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

          The Company shall deliver to the Trustee, within 30 days after it
becomes aware of the occurrence thereof, written notice of any event which with
the giving of notice or the lapse of time, or both, would become an Event of
Default under clause (3) or clause (4) above, its status and what action the
Company is taking or proposes to take with respect thereto.

          SECTION 6.02  Acceleration. If an Event of Default (other than an
Event of Default specified in Section 6.01(e) or (f) in respect of the Company)
occurs and is continuing, the Trustee by written Notice to the Company, or the
Holders of at least 25% in aggregate Principal Amount at Maturity of the
Securities at the time outstanding by notice to the Company and the Trustee, may
declare the Issue Price plus accrued Original Issue Discount and any accrued and
unpaid cash interest (or if the Securities have been converted to semiannual
coupon notes following a Tax Event, the Restated Principal Amount, plus accrued
interest), including accrued and unpaid Contingent Cash Interest, through the
date of declaration on all the Securities to be immediately due and payable.
Upon such a declaration, such Issue Price plus accrued Original Issue Discount,
and such accrued and unpaid interest, if any, shall be due and payable
immediately. If an Event of Default specified in Section 6.01(e) or (f) occurs
in respect of the Company and is continuing, the Issue Price plus accrued
Original Issue Discount and any accrued and unpaid cash interest (or, if the
Securities have been converted to semiannual coupon notes following a Tax Event,
the Restated Principal Amount, plus accrued interest), including accrued and
unpaid Contingent Cash Interest, on all the Securities shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders. The Holders of a majority in aggregate
Principal Amount at Maturity of the Securities at the time outstanding, by
notice to the Trustee (and without notice to any other

                                       41

<PAGE>

Securityholder) may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of the Issue Price
plus accrued Original Issue Discount and any accrued and unpaid cash interest
(or, if the Securities have been converted to semiannual coupon notes following
a Tax Event, the Restated Principal Amount, plus accrued interest), including
accrued and unpaid Contingent Cash Interest, that have become due solely as a
result of acceleration and if all amounts due to the Trustee under Section 7.07
hereof have been paid. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

          SECTION 6.03  Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of the Issue Price plus accrued Original Issue Discount and any accrued and
unpaid cash interest (or, if the Securities have been converted to semiannual
coupon notes following a Tax Event, the Restated Principal Amount, plus accrued
interest), including accrued and unpaid Contingent Cash Interest, on the
Securities or to enforce the performance of any provision of the Securities or
this Indenture.

          The Trustee may maintain a proceeding even if the Trustee does not
possess any of the Securities or does not produce any of the Securities in the
proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default. Except as set forth in Section 2.07 hereof, no remedy is
exclusive of any other remedy. All available remedies are cumulative.

          SECTION 6.04  Waiver of Past Defaults. Subject to Section 6.02, the
Holders of a majority in aggregate Principal Amount at Maturity of the
Securities at the time outstanding, by notice to the Trustee (and without notice
to any other Securityholder), may waive an existing Default and its consequences
except (a) an Event of Default described in Section 6.01(a) or (b), (b) a
Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Securityholder affected or (c) a Default which
constitutes a failure to convert any Security in accordance with the terms of
Article 11. When a Default is waived, it is deemed cured, but no such waiver
shall extend to any subsequent or other Default or impair any consequent right.
This Section 6.04 shall be in lieu of Section 316(a)1(B) of the TIA and such
Section 316(a)1(B) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

          SECTION 6.05  Control by Majority. The Holders of a majority in
aggregate Principal Amount at Maturity of the Securities at the time outstanding
may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or of exercising any trust or power conferred on
the Trustee. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or that the Trustee determines in good
faith is unduly prejudicial to the rights of other Securityholders or would
involve the Trustee in personal liability unless the Trustee is offered
indemnity satisfactory to it. This Section 6.05 shall be in lieu of Section
316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded
from this Indenture, as permitted by the TIA.

          SECTION 6.06  Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:

                                       42

<PAGE>

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

          (b)  the Holders of at least 25% in aggregate Principal Amount at
               Maturity of the Securities at the time outstanding make a written
               request to the Trustee to pursue the remedy;

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

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

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

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

          SECTION 6.07  Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of the Principal Amount at Maturity (or if the Securities have been
converted to semiannual coupon notes following a Tax Event pursuant to Article
10 hereof, the Restated Principal Amount, plus accrued cash interest), Issue
Price plus accrued Original Issue Discount, Redemption Price, Purchase Price,
Change in Control Purchase Price, or cash interest, including Contingent Cash
Interest, in respect of the Securities held by such Holder, on or after the
respective due dates expressed in the Securities or any Redemption Date, and to
convert the Securities in accordance with Article 11 hereof, or to bring suit
for the enforcement of any such payment on or after such respective dates or the
right to convert, shall not be impaired or affected adversely without the
consent of such Holder.

          SECTION 6.08  Collection Suit by Trustee. If an Event of Default
described in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Company for the whole amount owing with respect to the Securities and the
amounts provided for in Section 7.07 hereof.

          SECTION 6.09  Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the Principal Amount at Maturity, Restated
Principal Amount, Issue Price plus accrued Original Issue Discount, cash
interest, including Contingent Cash Interest, Redemption Price, Purchase Price,
Change in Control Purchase Price shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of any such amount)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                                       43

<PAGE>

          (a)  to file and prove a claim for the whole amount of the Principal
Amount at Maturity, Restated Principal Amount, Issue Price plus accrued Original
Issue Discount, cash interest, including Contingent Cash Interest, Redemption
Price, Purchase Price or Change in Control Purchase Price (or, if the Securities
have been converted to semiannual coupon notes following a Tax Event, the
Restated Principal Amount, plus accrued interest), as the case may be, and to
file such other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel or any other amounts due the Trustee under Section 7.07 hereof) and
of the Holders allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 hereof.

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

          SECTION 6.10  Priorities. If the Trustee collects any money pursuant
to this Article 6, it shall pay out the money in the following order:

          FIRST: to the Trustee for amounts due under Section 7.07 hereof;

          SECOND: to Securityholders for amounts due and unpaid on the
          Securities for the Principal Amount at Maturity, Restated Principal
          Amount, Issue Price plus accrued Original Issue Discount, cash
          interest, including Contingent Cash Interest, Redemption Price,
          Purchase Price or Change in Control Purchase Price (or, if the
          Securities have been converted to semiannual coupon notes following a
          Tax Event, the Restated Principal Amount, plus accrued cash interest),
          as the case may be, ratably, without preference or priority of any
          kind, according to such amounts due and payable on the Securities; and

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

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder and the Company a
notice that states the record date, the payment date and the amount to be paid.

          SECTION 6.11  Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or

                                       44

<PAGE>

omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant (other than the Trustee) in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in aggregate Principal Amount at Maturity of the
Securities at the time outstanding. This Section 6.11 shall be in lieu of
Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded
from this Indenture, as permitted by the TIA.

          SECTION 6.12  Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other law
wherever enacted, now or at any time hereafter in force, which would prohibit or
forgive the Company from paying all or any portion of the Principal Amount at
Maturity, Restated Principal Amount, Issue Price plus accrued Original Issue
Discount, cash interest, including Contingent Cash Interest, Redemption Price,
Purchase Price or Change in Control Purchase Price (or, if the Securities have
been converted to semiannual coupon notes following a Tax Event, the Restated
Principal Amount, plus accrued interest), as contemplated herein, or which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

                                    ARTICLE 7
                                     TRUSTEE

          SECTION 7.01  Duties of Trustee.

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

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

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

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

                                       45

<PAGE>

     requirements of this Indenture, but need not confirm or investigate the
     accuracy of mathematical calculations or other facts stated therein.

This Section 7.01(b) shall be in lieu of Section 315(a) of the TIA and such
Section 315(a) is hereby expressly excluded from this Indenture, as permitted by
the TIA.

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

          (i)   this paragraph (c) does not limit the effect of paragraph (b) of
                this Section 7.01;

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

          (iii) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05 hereof.

Subparagraphs (c)(i), (ii) and (iii) of this Section 7.01 shall be in lieu of
Sections 315(d)(1), 315(d)(2) and 315(d)(3) of the TIA and such Sections
315(d)(1), 315(d)(2) and 315(d)(3) are hereby expressly excluded from this
Indenture, as permitted by the TIA.

          (d)   Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 7.01.

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

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

          SECTION 7.02  Rights of Trustee. Subject to its duties and
responsibilities under the provisions of Section 7.01 hereof, and, except as
expressly excluded from this Indenture pursuant to said Section 7.01 hereof,
subject also to its duties and responsibilities under the TIA:

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

                                       46

<PAGE>

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

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

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

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

          (f)  the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby;

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

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

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

          (j)  the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be

                                       47

<PAGE>

enforceable by, the Trustee in each of its capacities hereunder, and to each
agent, custodian and other Person employed to act hereunder;

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

          (l)  the permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as duties.

          SECTION 7.03  Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion
Agent or co-registrar may do the same with like rights. However, the Trustee
must comply with Sections 7.10 and 7.11 hereof.

          SECTION 7.04  Trustee's Disclaimer. The Trustee makes no
representation as to the validity or adequacy of this Indenture or the
Securities, it shall not be accountable for the Company's use or application of
the proceeds from the Securities, it shall not be responsible for any statement
in the registration statement for the Securities under the Securities Act or in
the Indenture or the Securities (other than its certificate of authentication),
or the determination as to which beneficial owners are entitled to receive any
notices hereunder.

          SECTION 7.05  Notice of Defaults. If a Default occurs and if it is
known to a Responsible Officer of the Trustee, the Trustee shall give to each
Securityholder notice of the Default within 90 days after such Responsible
Officer obtains knowledge of such Default unless such Default shall have been
cured or waived before the giving of such notice. Except in the case of a
Default described in Section 6.01(a) or (b) hereof, the Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of Securityholders.
The second sentence of this Section 7.05 shall be in lieu of the proviso to
Section 315(b) of the TIA and such proviso is hereby expressly excluded from
this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have
knowledge of a Default unless a Responsible Officer of the Trustee has received
written notice of such Default.

          SECTION 7.06  Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the
Trustee shall mail to each Securityholder a brief report dated as of such May 15
that complies with TIA Section 313(a), if required by such Section 313(a). The
Trustee also shall comply with TIA Section 313(b).

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC (but only if this Indenture is then qualified under
the TIA) and with each securities exchange, if any, on which the Securities are
listed. The Company agrees to promptly notify the

                                       48

<PAGE>

Trustee whenever the Securities become listed on any securities exchange and of
any delisting thereof.

          SECTION 7.07  Compensation and Indemnity. The Company agrees:

          (a)  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 all services rendered by it hereunder (which compensation shall not
be limited (to the extent permitted by law) by any provision of law in regard to
the compensation of a trustee of an express trust);

          (b)  to reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the reasonable
compensation and the expenses, advances 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

          (c)  to indemnify the Trustee and its agents for, and to hold them
harmless against, any loss, liability or expense (including reasonable
attorney's fees and expenses and taxes (other than taxes based upon, measured by
or determined by the income of the Trustee)) incurred without negligence or bad
faith on their part, arising out of or in connection with the acceptance or
administration of this trust, including the reasonable costs and expenses of
defending itself against any claim (whether asserted by the Company or any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

          To secure the Company's payment obligations in this Section 7.07, the
Holders shall have been deemed to have granted to the Trustee a lien prior to
the Securities on all money or property held or collected by the Trustee, except
that held in trust to pay the Principal Amount at Maturity, Issue Price plus
accrued Original Issue Discount, Redemption Price, Purchase Price, Change in
Control Purchase Price or cash interest, if any, as the case may be, on
particular Securities.

          The Company's payment obligations pursuant to this Section 7.07 shall
survive the discharge of this Indenture and the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.01(e) or (f) hereof, the expenses including the
reasonable charges and expenses of its counsel, are intended to constitute
expenses of administration under any Bankruptcy Law.

          SECTION 7.08  Replacement of Trustee. The Trustee may resign by so
notifying the Company; provided, however, no such resignation shall be effective
until a successor Trustee has accepted its appointment pursuant to this Section
7.08. The Holders of a majority in aggregate Principal Amount at Maturity of the
Securities at the time outstanding may remove the Trustee by so notifying the
Trustee and the Company. The Company shall remove the Trustee if:

          (a)  the Trustee fails to comply with Section 7.10 hereof;

          (b)  the Trustee is adjudged bankrupt or insolvent;

                                       49

<PAGE>

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

          (d)  the Trustee otherwise becomes incapable of acting.

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

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company satisfactory in form and
substance to the retiring Trustee and the Company. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held
by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07 hereof.

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

          If the Trustee fails to comply with Section 7.10 hereof, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

          SECTION 7.09  Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation, the resulting,
surviving or transferee corporation without any further act shall be the
successor Trustee.

          SECTION 7.10  Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee
(or its parent holding company) shall have a combined capital and surplus of at
least $50,000,000 as set forth in its most recent published annual report of
condition. Nothing herein contained shall prevent the Trustee from filing with
the Commission the application referred to in the penultimate paragraph of TIA
Section 310(b).

          SECTION 7.11  Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                   ARTICLE 8
                             DISCHARGE OF INDENTURE

          SECTION 8.01  Discharge of Liability on Securities. When (a) the
Company delivers to the Trustee all outstanding Securities (other than
Securities replaced

                                       50

<PAGE>

pursuant to Section 2.07 hereof) for cancellation or (b) all outstanding
Securities have become due and payable and the Company irrevocably deposits with
the Trustee, the Paying Agent (if the Paying Agent is not the Company or any of
its Affiliates) or the Conversion Agent cash or, if expressly permitted by the
terms of the Securities or the Indenture, Common Stock sufficient to pay all
amounts due and owing on all outstanding Securities (other than Securities
replaced pursuant to Section 2.07 hereof), and if in either case the Company
pays all other sums payable hereunder by the Company, then this Indenture shall,
subject to Section 7.07 hereof, cease to be of further effect. The Trustee shall
join in the execution of a document prepared by the Company acknowledging
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and Opinion of Counsel and at the cost
and expense of the Company.

          SECTION 8.02  Repayment to the Company. The Trustee and the Paying
Agent shall return to the Company upon written request any money or securities
held by them for the payment of any amount with respect to the Securities that
remains unclaimed for two years, subject to applicable unclaimed property law.
After return to the Company, Holders entitled to the money or securities must
look to the Company for payment as general creditors unless an applicable
abandoned property law designates another person and the Trustee and the Paying
Agent shall have no further liability to the Securityholders with respect to
such money or securities for that period commencing after the return thereof.

                                   ARTICLE 9
                                   AMENDMENTS

          SECTION 9.01  Without Consent of Holders. The Company and the Trustee
may amend this Indenture or the Securities without the consent of any
Securityholder:

          (a)  to cure any ambiguity, omission, defect or inconsistency;

          (b)  to comply with Article 5 or Section 11.14 hereof;

          (c)  to secure the Company's obligations under the Securities and this
     Indenture;

          (d)  to add to the Company's covenants for the benefit of the
     Securityholders or to surrender any right or power conferred upon the
     Company;

          (e)  to make any change to comply with the TIA, or any amendment
     thereto, or to comply with any requirement of the SEC in connection with
     the qualification of the Indenture under the TIA, or as necessary in
     connection with the registration of the Securities under the Securities
     Act; or

          (f)  to make any change that does not adversely affect the rights of
     any Holders (it being understood that any amendment described in clause (a)
     of this Section 9.01 made solely to conform this Indenture to the final
     offering memorandum provided to investors in connection with the initial
     offering of the Securities will be deemed not to adversely affect the
     rights or interests of Holders).

                                       51

<PAGE>

          SECTION 9.02  With Consent of Holders. With the written consent of the
Holders of at least a majority in aggregate Principal Amount at Maturity of the
Securities at the time outstanding, the Company and the Trustee may amend this
Indenture or the Securities. However, without the consent of each Securityholder
affected, an amendment to this Indenture or the Securities may not:

          (a)  reduce the percentage in Principal Amount at Maturity of
     Securities whose Holders must consent to an amendment;

          (b)  make any change in the manner or rate of accrual of Original
     Issue Discount or cash interest, including Contingent Cash Interest, reduce
     the rate of cash interest, including Contingent Cash Interest, referred to
     in paragraph 1 of the Securities, or extend the time for payment of
     Original Issue Discount or cash interest, including Contingent Cash
     Interest, on any Security;

          (c)  reduce the Principal Amount at Maturity, Restated Principal
     Amount, Issue Price, accrued Original Issue Discount or cash interest, with
     respect to any Security, or extend the Stated Maturity of any Security;

          (d)  reduce the Redemption Price, Purchase Price or Change in Control
     Purchase Price of any Security;

          (e)  make any Security payable in money or securities other than that
     stated in the Security;

          (f)  make any change in Article 10 hereof, or this Section 9.02,
     except to increase any percentage set forth therein;

          (g)  make any change that adversely affects the right to convert any
     Security;

          (h)  make any change that adversely affects the right to require the
     Company to purchase the Securities in accordance with the terms thereof and
     this Indenture; or

          (i)  impair the right to institute suit for the enforcement of any
     payment with respect to, or conversion of, the Securities.

          It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

          After an amendment under this Section 9.02 becomes effective, the
Company shall mail to each Holder a notice briefly describing the amendment.

          SECTION 9.03  Compliance with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article 9 shall comply with the TIA.

          SECTION 9.04  Revocation and Effect of Consents, Waivers and Actions.
Until an amendment, consent, waiver or other action by Holders becomes
effective, a consent

                                       52

<PAGE>

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

          SECTION 9.05  Notation on or Exchange of Securities. Securities
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article 9 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 Board of Directors, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for outstanding
Securities.

          SECTION 9.06  Trustee to Sign Supplemental Indentures. The Trustee
shall sign any supplemental indenture authorized pursuant to this Article 9 if
the amendment contained therein does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need
not, sign such supplemental indenture. In signing such supplemental indenture
the Trustee shall receive, and (subject to the provisions of Section 7.01
hereof) shall be fully protected in relying upon, in addition to the documents
required by Section 14.04 hereof, an Officers' Certificate and an Opinion of
Counsel stating that such amendment is authorized or permitted by this
Indenture.

          SECTION 9.07  Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

                                   ARTICLE 10
                          SPECIAL TAX EVENT CONVERSION

          SECTION 10.01 Optional Conversion to Semiannual Coupon Note upon Tax
Event. From and after (a) the date of the occurrence of a Tax Event (the "Tax
Event Date") subsequent to May 14, 2007 and (b) the date the Company exercises
the option provided for in this Section 10.01, whichever is later (the "Option
Exercise Date"), at the option of the Company, interest in lieu of future
Original Issue Discount or cash interest shall accrue at the rate of 3% per
annum, calculated on a semiannual bond equivalent basis, on a Restated Principal
Amount, per $1,000 original Principal Amount at Maturity (the "Restated
Principal Amount") equal to the Issue Price plus Original Issue Discount accrued
through the Option Exercise Date and shall be payable semiannually on May 14 and
November 14 of each year (each an "Interest Payment Date") to Holders of record
at the close of business on the April 29 or October 30, respectively, (each a
"Regular Record Date") immediately preceding such Interest Payment Date.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months and

                                       53

<PAGE>

will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Option Exercise Date. Within 15 days of the
occurrence of a Tax Event, the Company shall deliver a written notice of such
Tax Event by facsimile and first-class mail to the Trustee and within 15 days of
its exercise of such option the Company shall deliver a written notice of the
Option Exercise Date by facsimile and first-class mail to the Trustee and by
first class mail to the Holders of the Securities. From and after the Option
Exercise Date, (a) the Company shall be obligated to pay at Stated Maturity, in
lieu of the Principal Amount at Maturity of a Security, the Restated Principal
Amount thereof plus accrued and unpaid interest on such Security and (b) "Issue
Price and accrued Original Issue Discount," "Issue Price plus Original Issue
Discount" or similar words, as used herein, shall mean Restated Principal Amount
plus accrued and unpaid interest with respect to any Security. Securities
authenticated and delivered after the Option Exercise Date may, and shall if
required by the Trustee, bear a notation in a form approved by the Trustee as to
the conversion of the Securities to semiannual coupon notes. No other changes to
this Indenture shall result as a result of the events described in this Section
10.01.

                                   ARTICLE 11
                                   CONVERSION

          SECTION 11.01 Conversion Privilege. A Holder of a Security may convert
such Security into shares of Common Stock at any time prior to the close of
business on May 14, 2032, subject to the provisions of this Article 11 and
paragraph 9 of the Securities. The number of shares of Common Stock issuable
upon conversion of a Security per $1,000 of Principal Amount at Maturity thereof
(the "Conversion Rate") shall be determined in accordance with the provisions of
paragraph 9 of the Securities.

          A Holder may convert a portion of the Principal Amount at Maturity of
a Security if the portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to conversion of all of a Security also
apply to conversion of a portion of a Security.

          SECTION 11.02 Conversion Procedure. To convert a Security, a Holder
must satisfy the requirements in paragraph 9 in the Securities. The date on
which the Holder satisfies all those requirements is the conversion date (the
"Conversion Date"). As soon as practicable after the Conversion Date but in any
event no later than the seventh Business Day following the Conversion Date, the
Company shall deliver to the Holder, through the Conversion Agent, a certificate
for the number of full shares of Common Stock issuable upon the conversion and
cash in lieu of any fractional share determined pursuant to Section 11.03
hereof. The Company shall determine such full number of shares and the amounts
of the required cash with respect to any fractional share, and shall set forth
such information in an Officer's certificate delivered to the Conversion Agent.
The Conversion Agent shall have no duties under this paragraph unless and until
it has received such certificate.

          The Person in whose name the certificate is registered shall be
treated as a stockholder of record on and after the Conversion Date; provided,
however, that no surrender of a Security on any date when the stock transfer
books of the Company shall be closed shall be effective to constitute the Person
or Persons entitled to receive the shares of Common Stock upon such conversion
as the record holder or holders of such shares of Common Stock on such

                                       54

<PAGE>

date, but such surrender shall be effective to constitute the Person or Persons
entitled to receive such shares of Common Stock as the record holder or holders
thereof for all purposes at the close of business on the next succeeding day on
which such stock transfer books are open; such conversion shall be at the
Conversion Rate in effect on the date that such Security shall have been
surrendered for conversion, as if the stock transfer books of the Company had
not been closed. Upon conversion of a Security, such Person shall no longer be a
Holder of such Security.

          No payment or adjustment will be made for dividends on, or other
distributions with respect to, any Common Stock except as provided in this
Article 11. On conversion of a Security, that portion of accrued Original Issue
Discount and cash interest, including Contingent Cash Interest, if any,
attributable to the period from the Issue Date of the Security through the
Conversion Date, with respect to the converted Security shall not be cancelled,
extinguished or forfeited, but rather shall be deemed to be paid in full to the
Holder thereof through delivery of the Common Stock (together with the cash
payment, if any, in lieu of fractional shares) in exchange for the Security
being converted pursuant to the provisions hereof; and the fair market value of
such shares of Common Stock (together with any such cash payment in lieu of
fractional shares) shall be treated as issued, to the extent thereof, first in
exchange for accrued Original Issue Discount and cash interest, including
Contingent Cash Interest, if any, through the Conversion Date, and the balance,
if any, of such fair market value of such Common Stock (and any such cash
payment) shall be treated as issued in exchange for the Issue Price of the
Security being converted pursuant to the provisions hereof. Notwithstanding the
foregoing, accrued cash interest will be payable upon conversion of Securities
made concurrently with or after acceleration of Securities following an Event of
Default.

          If the Holder converts more than one Security at the same time, the
number of shares of Common Stock issuable upon the conversion shall be based on
the total Principal Amount at Maturity of the Securities converted.

          A Security surrendered for conversion based on (a) the Common Stock
price may be surrendered for conversion until the close of business on May 14,
2032, (b) the Security being called for redemption may be surrendered for
conversion at any time prior to the close of business on the second Business Day
immediately preceding the Redemption Date, even if it is not otherwise
convertible at such time, (c) a credit downgrade may be surrendered for
conversion until the close of business on any Business Day during the period of
the continuance of the credit downgrade as more fully described in paragraph 9
of the Security, and (d) upon the occurrence of certain corporate transactions
more fully described in paragraph 9 of the Security may be surrendered for
conversion at any time from and after the date which is 15 days prior to the
anticipated effective date of such transaction until 15 days after the actual
date of such transaction, and if such day is not a Business Day, the next
occurring Business Day following such day.

          Upon surrender of a Security that is converted in part, the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder, a
new Security in an authorized denomination equal in Principal Amount at Maturity
to the unconverted portion of the Security surrendered.

                                       55

<PAGE>

          SECTION 11.03  Fractional Shares. The Company will not issue a
fractional share of Common Stock upon conversion of a Security. Instead, the
Company will deliver cash for the current market value of the fractional share.
The current market value of a fractional share shall be determined, to the
nearest 1/1,000th of a share, by multiplying the per share Sale Price of the
Common Stock, on the last Trading Day prior to the Conversion Date, by the
fractional amount and rounding the product to the nearest whole cent.

          SECTION 11.04  Taxes on Conversion. If a Holder converts a Security,
the Company shall pay any documentary, stamp or similar issue or transfer tax
due on the issue of shares of Common Stock upon the conversion. However, the
Holder shall pay any such tax which is due because the Holder requests the
shares to be issued in a name other than the Holder's name and any income tax
which is imposed on the Holder as a result of the conversion. The Conversion
Agent may refuse to deliver the certificates representing the Common Stock being
issued in a name other than the Holder's name until the Conversion Agent
receives a sum sufficient to pay any tax which will be due because the shares
are to be issued in a name other than the Holder's name. Nothing herein shall
preclude the Company from any tax withholding or directing the withholding of
any tax required by law or regulations.

          SECTION 11.05  Company to Provide Stock. The Company shall, prior to
issuance of any Securities under this Article 11, and from time to time as may
be necessary, reserve out of its authorized but unissued Common Stock a
sufficient number of shares of Common Stock to permit the conversion of the
Securities.

          All shares of Common Stock delivered upon conversion of the Securities
shall be newly issued shares or treasury shares, shall be duly and validly
issued and fully paid and nonassessable and shall be free from preemptive rights
and free of any lien or adverse claim created by the Company.

          The Company will endeavor promptly to comply with all federal and
state securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Securities, if any, and will list or cause to have
quoted such shares of Common Stock on each national securities exchange or in
the over-the-counter market or such other market on which the Common Stock is
then listed or quoted.

          SECTION 11.06  Adjustment for Change in Capital Stock. Except as set
forth in Section 11.14 hereof, if, after the Issue Date of the Securities, the
Company:

          (a)  pays a dividend or makes a distribution on its Common Stock in
shares of its Common Stock or other Capital Stock;

          (b)  subdivides its outstanding shares of Common Stock into a greater
number of shares;

          (c)  pays a dividend or makes a distribution of its Common Stock in
shares of its Capital Stock (other than Common Stock or rights, warrants or
options for its Capital Stock);

          (d)  combines its outstanding shares of Common Stock into a smaller
number of shares; or

                                       56

<PAGE>

          (e)  issues by reclassification of its Common Stock any shares of its
Capital Stock (other than rights, warrants or options for its Capital Stock);

then the conversion privilege and the Conversion Rate in effect immediately
prior to such action shall be adjusted so that the Holder of a Security
thereafter converted may receive the number of shares or other units of Capital
Stock of the Company which such Holder would have owned immediately following
such action if such Holder had converted the Security immediately prior to such
action.

          The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.

          SECTION 11.07  Adjustment for Rights Issue. Except as set forth in
Sections 11.14 and 11.19 hereof, if after the Issue Date, the Company
distributes any rights, warrants or options to all holders of its Common Stock
entitling them, for a period expiring within 60 days of the Issue Date, to
purchase shares of Common Stock at a price per share less than the Sale Price of
the Common Stock as of the Time of Determination, the Conversion Rate shall be
adjusted in accordance with the formula:

                           R'  =     R (O + N)
                                -------------------
                                 (O + [(N x P)/M])

     where:

     R' = the adjusted Conversion Rate.

     R = the current Conversion Rate.

     O = the number of shares of Common Stock outstanding on the record date for
the distribution to which this Section 11.07 is being applied.

     N = the number of additional shares of Common Stock offered pursuant to the
distribution.

     P = the offering price per share of the additional shares.

          M = the Average Sale Price.

          The adjustment shall become effective immediately after the record
date for the determination of shareholders entitled to receive the rights,
warrants or options to which this Section 11.07 applies. If all of the shares of
Common Stock subject to such rights, warrants or options have not been issued
when such rights, warrants or options expire, then the Conversion Rate shall
promptly be readjusted to the Conversion Rate which would then be in effect had
the adjustment upon the issuance of such rights, warrants or options been made
on the basis of the actual number of shares of Common Stock issued upon the
exercise of such rights, warrants or options.

                                       57

<PAGE>

          No adjustment shall be made under this Section 11.07 if the
application of the formula stated above in this Section 11.07 would result in a
value of R' that is equal to or less than the value of R.

          SECTION 11.08  Adjustment for Other Distributions. If, after the Issue
Date of the Securities, the Company distributes to all holders of its Common
Stock any of its assets or evidence of indebtedness or any rights, warrants or
options to purchase securities of the Company (including securities or cash, but
excluding (x) distributions of Capital Stock referred to in Section 11.06 hereof
and distributions of rights, warrants or options referred to in Section 11.07
hereof and (y) cash dividends or other cash distributions that are paid out of
consolidated current net earnings or earnings retained in the business as shown
on the books of the Company unless such cash dividends or other cash
distributions are Extraordinary Cash Dividends), the Conversion Rate shall be
adjusted, in accordance with the formula:

                   R' =  R x M
                        -------
                         M - F

where:

     R' = the adjusted Conversion Rate.

     R = the current Conversion Rate.

     M = the Average Sale Price.

     F = the fair market value (on the record date for the distribution to which
this Section 11.08 applies) of the assets, securities, rights, warrants or
options to be distributed in respect of each share of Common Stock in the
distribution to which this Section 11.08 is being applied (including, in the
case of cash dividends or other cash distributions giving rise to an adjustment,
all such cash distributed concurrently).

          The Board of Directors shall determine fair market values for the
purposes of this Section 11.08.

          The adjustment shall become effective immediately after the record
date for the determination of shareholders entitled to receive the distribution
to which this Section 11.08 applies.

          For purposes of this Section 11.08, the term "Extraordinary Cash
Dividend" shall mean any cash dividend or distribution with respect to the
Common Stock the amount of which, together with the aggregate amount of cash
dividends on the Common Stock to be aggregated with such cash dividend in
accordance with the provisions of this paragraph, equals or exceeds the
threshold percentage set forth in item (a) below. For purposes of item (a)
below, the "Ex-Dividend Measurement Period" with respect to a cash dividend on
the Common Stock shall mean the 365 consecutive day period ending on the date
prior to the Ex-Dividend Time with respect to such cash dividend, and the
"Relevant Cash Dividends" with respect to a cash dividend on the Common Stock
shall mean the cash dividends on the Common Stock with Ex-Dividend Times
occurring in the Ex-Dividend Measurement Period.

                                       58

<PAGE>

          (a)  If, upon the date prior to the Ex-Dividend Time with respect to a
               cash dividend on the Common Stock, the aggregate amount of such
               cash dividend together with the amounts of all Relevant Cash
               Dividends equals or exceeds on a per share basis 5% of the Sale
               Price of the Common Stock on the last Trading Day preceding the
               date of declaration by the Board of Directors of the cash
               dividend or distribution with respect to which this provision is
               being applied, then such cash dividend together with all Relevant
               Cash Dividends, shall be deemed to be an Extraordinary Cash
               Dividend and for purposes of applying the formula set forth above
               in this Section 11.08, the value of "F" shall be equal to (y) the
               aggregate amount of such cash dividend together with the amount
               of all Relevant Cash Dividends, minus (z) the aggregate amount of
               all Relevant Cash Dividends for which a prior adjustment in the
               Conversion Rate was previously made under this Section 11.08.

          In making the determinations required by item (a) above, the amount of
          cash dividends paid on a per share basis and the amount of any
          Relevant Cash Dividends specified in item (a) above, shall be
          appropriately adjusted to reflect the occurrence during such period of
          any event described in Section 11.06 hereof.

          SECTION 11.09  When Adjustment May Be Deferred. No adjustment in the
Conversion Rate need be made unless the adjustment would require an increase or
decrease of at least 1% in the Conversion Rate. Any adjustments that are not
made shall be carried forward and taken into account in any subsequent
adjustment and all adjustments that are made and carried forward shall be taken
in the aggregate in order to determine if the 1% threshold is met.

          All calculations under this Article 11 shall be made to the nearest
cent or to the nearest 1/1,000th of a share, as the case may be.

          SECTION 11.10  When No Adjustment Required. No adjustment need be made
for a transaction referred to in Section 11.06, 11.07, 11.08 or 11.14 hereof if
Securityholders may participate in the transaction. Such participation by
Securityholders may include participation without conversion or upon conversion,
provided that if such participation is upon conversion, an adjustment shall be
made at such time as the Securityholders are no longer entitled to participate.

          No adjustment need be made for rights to purchase Common Stock
pursuant to a Company plan for reinvestment of dividends or interest.

          Unless otherwise required by a provision of this Article 11, no
adjustment need be made for a change in the par value or no par value of the
Common Stock.

          To the extent the Securities become convertible pursuant to this
Article 11 into cash, no adjustment need be made thereafter as to the cash.
Interest will not accrue on the cash.

          No adjustment will be made pursuant to this Article 11 that would
result, through the application of two or more provisions hereof, in the
duplication of any adjustment.

                                       59

<PAGE>

          SECTION 11.11  Notice of Adjustment. Whenever the Conversion Rate is
adjusted, the Company shall promptly mail to Securityholders a notice of the
adjustment. The Company shall file with the Trustee and the Conversion Agent
such notice and a certificate from the Company's independent public accountants
briefly stating the facts requiring the adjustment and the manner of computing
it. Upon receipt by it of such notice, and at the written request of the
Company, the Conversion Agent will promptly mail such notice to Securityholders
at the Company's expense. The certificate shall be conclusive evidence that the
adjustment is correct. Neither the Trustee nor any Conversion Agent shall be
under any duty or responsibility with respect to any such certificate except to
exhibit the same to any Holder desiring inspection thereof.

          SECTION 11.12  Voluntary Increase. The Company from time to time may
increase the Conversion Rate by any amount for any period of time. Whenever the
Conversion Rate is increased, the Company shall mail to Securityholders and file
with the Trustee and the Conversion Agent a notice of the increase. The Company
shall mail the notice at least 15 days before the date the increased Conversion
Rate takes effect. The notice shall state the increased Conversion Rate and the
period it will be in effect.

          A voluntary increase of the Conversion Rate does not change or adjust
the Conversion Rate otherwise in effect for purposes of Section 11.06, 11.07 or
11.08 or 11.14 hereof.

          SECTION 11.13  Notice of Certain Transactions. If:

          (a)  the Company takes any action that would require an adjustment in
the Conversion Rate pursuant to Section 11.06, 11.07 or 11.08 hereof (unless no
adjustment is to occur pursuant to Section 11.10 hereof); or

          (b)  the Company takes any action that would require a supplemental
indenture pursuant to Section 11.14; or

          (c)  there is a liquidation or dissolution of the Company;

then the Company shall mail to Securityholders and file with the Trustee and the
Conversion Agent a notice stating the proposed record date for a dividend or
distribution or the proposed effective date of a subdivision, combination,
reclassification, consolidation, merger, binding share exchange, transfer,
liquidation or dissolution. The Company shall file and mail the notice at least
15 days before such date. Failure to file or mail the notice or any defect in it
shall not affect the validity of the transaction.

          SECTION 11.14  Reorganization of Company; Special Distributions. If
the Company is a party to a transaction subject to Article 5 hereof (other than
a sale of all or substantially all of the assets of the Company in a transaction
in which the holders of Common Stock immediately prior to such transaction do
not receive securities, cash, property or other assets of the Company or any
other Person) or a merger or binding share exchange which reclassifies or
changes its outstanding Common Stock, the Person obligated to deliver
securities, cash or other assets upon conversion of Securities shall, no later
than the closing date of such transaction, enter into a supplemental indenture.
If the issuer of securities deliverable upon

                                       60

<PAGE>

conversion of Securities is an Affiliate of the successor Company, that issuer
shall, no later than the closing date of such transaction, join in the
supplemental indenture.

          The supplemental indenture shall provide that the Holder of a Security
may convert it into the kind and amount of securities, cash or other assets
which such Holder would have received immediately after the consolidation,
merger, binding share exchange or transfer if such Holder had converted the
Security immediately before the effective date of the transaction, assuming (to
the extent applicable) that such Holder was not a constituent Person or an
Affiliate of a constituent Person to such transaction. The supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as
may be practical to the adjustments provided for in this Article 11. The
successor Company shall mail to Securityholders a notice briefly describing the
supplemental indenture.

          If this Section applies, neither Section 11.06 nor 11.07 hereof
applies.

          If the Company makes a distribution to all holders of its Common Stock
of any of its assets, or debt securities or any rights, warrants or options to
purchase securities of the Company that would otherwise result in an adjustment
in the Conversion Rate pursuant to the provisions of Section 11.08 hereof, then,
from and after the record date for determining the holders of Common Stock
entitled to receive the distribution, a Holder of a Security that converts such
Security in accordance with the provisions of this Indenture shall upon such
conversion be entitled to receive, in addition to the shares of Common Stock
into which the Security is convertible, the kind and amount of securities, cash
or other assets comprising the distribution that such Holder would have received
if such Holder had converted the Security immediately prior to the record date
for determining the holders of Common Stock entitled to receive the
distribution.

          SECTION 11.15  Company Determination Final. Any determination that the
Company or the Board of Directors must make pursuant to Section 11.03, 11.06,
11.07, 11.08, 11.09, 11.10, 11.14 or 11.17 hereof is conclusive.

          SECTION 11.16  Trustee's Adjustment Disclaimer. The Trustee has no
duty to determine when an adjustment under this Article 11 should be made, how
it should be made or what it should be. The Trustee has no duty to determine
whether a supplemental indenture under Section 11.14 hereof need be entered into
or whether any provisions of any supplemental indenture are correct. The Trustee
shall not be accountable for and makes no representation as to the validity or
value of any securities or assets issued upon conversion of Securities. The
Trustee shall not be responsible for the Company's failure to comply with this
Article 11. Each Conversion Agent (other than the Company or an Affiliate of the
Company) shall have the same protection under this Section 11.16 as the Trustee.

          SECTION 11.17  Simultaneous Adjustments. In the event that this
Article 11 requires adjustments to the Conversion Rate under more than one of
Sections 11.06, 11.07 or 11.08 hereof, and the record dates for the
distributions giving rise to such adjustments shall occur on the same date, then
such adjustments shall be made by applying, first, the provisions of Section
11.06 hereof, second, the provisions of Section 11.08 hereof and, third, the
provisions of Section 11.07 hereof.

          SECTION 11.18  Successive Adjustments. After an adjustment to the
Conversion Rate under this Article 11, any subsequent event requiring an
adjustment under this Article 11 shall cause an adjustment to the Conversion
Rate as so adjusted.

          SECTION 11.19  Rights Issued in Respect of Common Stock Issued Upon
Conversion. Each share of Common Stock issued upon conversion of Securities
pursuant to this Article 11 shall be entitled to receive the appropriate number
of common stock or preferred stock purchase rights, as the case may be (the
"Rights"), if any, that all shares of Common Stock are entitled to receive and
the certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
shareholder rights agreement adopted by the Company, as the same may be amended
from time to time (in each case, a "Rights Agreement"). Provided that such
Rights Agreement requires that each share of Common Stock issued by the Company
(including those that might be issued upon conversion of Securities) at any time
prior to the distribution of separate certificates representing the Rights be
entitled to receive such Rights, then, notwithstanding anything else to the
contrary in this Article 11, there shall not be any adjustment to the conversion
privilege or Conversion Rate or any other term or provision of the Securities as
a result of the issuance of Rights, the distribution of separate certificates
representing the Rights, the exercise or redemption of such Rights in accordance
with any such Rights Agreement, or the termination or invalidation of such
Rights.

          SECTION 11.20  Company's Right to Elect to Pay Cash or Common Stock.
In lieu of delivery of Common Stock upon notice of conversion of any Securities
(for all or any portion of the Securities), the Company may elect to pay holders
surrendering Securities an amount in cash per Security (or a portion of a
Security) equal to the Average Sale Price of Common Stock for the five
consecutive Trading Days immediately following either (a) the date of notice of
election to deliver cash as described below if the Company has not given notice
of redemption, or (b) the conversion date, in the case of conversion following
the notice of redemption specifying that the Company intends to deliver cash
upon conversion, in either case multiplied by the Conversion Rate in effect on
that date. The Company will inform the Holders through the Trustee no later than
two business days following the Conversion Date of its election to deliver
shares of Common Stock or to pay cash in lieu of delivery of Common Stock,
unless the Company has already informed holders of its election in connection
with its optional redemption of the Securities pursuant to Section 3.1 herein.
If the Company elects to deliver all of such payment in Common Stock, the Common
Stock will be delivered through the Conversion Agent no later than the fifth
business day following the Conversion Date. If the Company elects to pay all or
a portion of such payment in cash, the payment, including any delivery of Common
Stock, will be made to Holders surrendering Securities no later than the tenth
business day following the applicable conversion date. If an Event of Default
(other than a default in a cash payment upon conversion of the Securities) has
occurred and is continuing, the Company may not pay cash upon conversion of any
Security or portion of a Security (other than cash for fractional shares).

                               PAYMENT OF INTEREST

          SECTION 12.01  Interest Payments. Interest on any Security that is
payable in cash, and is punctually paid or duly provided for, on any applicable
payment date shall be paid to the person in whose name that Security is
registered at the close of business on the Record Date or accrual date, as the
case may be, for such interest at the office or agency of the Company maintained
for such purpose. Each installment of semiannual or contingent interest on any
Security shall be paid in same-day funds by transfer to an account maintained by
the payee located inside the United States, if the Trustee shall have received
proper wire transfer instructions from such payee not later than the related
Record Date or accrual date, as the case may be, or, if no such instructions
have been received, by check drawn on a bank in New York City mailed to the
payee at its address set forth on the Registrar's books. In the case of a
permanent Global Security, semiannual or contingent interest payable on any
applicable payment date will be paid to the Depositary, with respect to that
portion of such permanent Global Security held for its account by Cede & Co. for
the purpose of permitting such party to credit the interest received by it in
respect of such permanent Global Security to the accounts of the beneficial
owners thereof.

          SECTION 12.02  Defaulted Interest. Except as otherwise specified with
respect to the Securities, any interest on any Security that is payable, but is
not punctually paid or duly provided for, within 30 days following any
applicable payment date (herein called "Defaulted Interest", which term shall
include any accrued and unpaid interest that has accrued on such defaulted
amount in accordance with paragraph 1 of the Securities), shall be paid by the
Company, at its election in each case (x) to the Holder as of Special Record
Date, as determined in accordance with clause (a) below, or (y) in the manner
set forth in clause (b) below:

          (a)  The Company may elect to make payment of any Defaulted Interest
     to the persons in whose names the 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 and the date of the proposed payment (which
     shall not be less than 20 days after such notice is received by the
     Trustee), and at the same time the Company shall deposit with the Trustee
     an amount of money equal to the aggregate amount proposed to be paid in
     respect of such Defaulted Interest or shall make arrangements satisfactory
     to the Trustee for such deposit on or 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.
     Thereupon the Trustee shall fix a special record date (the "Special Record
     Date") for the payment of such Defaulted Interest which 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 shall promptly notify the
     Company of such Special Record Date and, in the name and at the expense of
     the Company, shall cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be mailed, first-class
     postage prepaid, to each Holder of Securities at his address as it appears
     on the list of Securityholders maintained pursuant to Section 2.05 hereof
     not less than 10 days prior to such Special Record Date.

                                       63

<PAGE>

     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been mailed as aforesaid, such Defaulted
     Interest shall be paid to the persons in whose names the Securities are
     registered at the close of business on such Special Record Date and shall
     no longer be payable pursuant to the following clause (b) of this Section
     12.02.

          (b)  The Company may make payment of any Defaulted Interest on the
     Securities in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which such 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.

          SECTION 12.03  Interest Rights Preserved. Subject to the foregoing
provisions of this Article 12 and Section 2.06 hereof, 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 semiannual interest accrued
and unpaid, and to accrue, which were carried by such other Security.

                                   ARTICLE 13
                            CONTINGENT CASH INTEREST

          SECTION 13.01  Contingent Cash Interest. The Company shall make
Contingent Cash Interest payments to the Holders of Securities, as set forth in
Section 13.02 below, during any six month period commencing May 14 or November
14 beginning with the six-month period commencing on May 14, 2007 (each a
"Semiannual Period") if, but only if, the average of the Security Market Prices
of a Security for the five Trading Days in the relevant Five-Trading-Day
Measurement Period equals 120% or more of the Relevant Value of such Security.
During any Semiannual Period when Contingent Cash Interest is payable pursuant
to this section, each Contingent Cash Interest payment due and payable on each
$1,000 Principal Amount at Maturity shall be calculated for any quarterly period
within the applicable Semiannual Period, and in each instance shall equal the
greater of the applicable Conversion Rate at such time with respect to the
Securities as determined in accordance with Article 11 hereof and paragraph 9 of
the Securities, multiplied by the greater of (a) $0.105 and (b) the sum of all
Regular Cash Dividends paid by the Company per share on the Common Stock during
the applicable quarter of such Semiannual Period.

          As used in this Article 13, "Five-Trading-Day Measurement Period"
means the five Trading Days ending on the third Trading Day immediately
preceding the first day of the applicable Semiannual Period; provided, however,
that if the Company declares a dividend on the Common Stock for which the record
date (the "Common Stock Record Date") falls prior to the first day of the next
Semiannual Period, but the payment date for the Common Stock falls within such
Semiannual Period, then, the "Five-Trading-Day Measurement Period" shall mean
the five Trading Days ending on the third Trading Day immediately preceding such
Common Stock Record Date. "Relevant Value" means the sum of the Issue Price, the
accrued Original Issue Discount and accrued cash interest, if any, on such
Security to the day immediately preceding the first day of the applicable
Semiannual Period. "Security Market Price" means, as

                                       64

<PAGE>

of any date of determination, the average of the secondary market bid quotations
per $1,000 Principal Amount at Maturity of Securities obtained by the Bid
Calculation Agent for $5 million Principal Amount at Maturity of Securities at
approximately 4:00 p.m., New York City time, on such determination date from
three independent nationally recognized securities dealers (none of which shall
be an Affiliate of the Company) selected by the Company; provided, however, if
(a) at least three such bids are not obtained by the Bid Calculation Agent or
(b) in the Company's reasonable judgment, the bid quotations are not indicative
of the secondary market value of the Securities as of such determination date,
then the Securities Market Price for such determination date shall equal the
product of (i) the Conversion Rate in effect as of such determination date
multiplied by (ii) the average Sale Price of the Common Stock for the five
Trading Days ending on such determination date, appropriately adjusted to take
into account the occurrence, during the period commencing on the first of such
Trading Days during such five Trading Day period and ending on such
determination date, of any event described in Section 11.06, 11.07 or 11.08
hereof (subject to the conditions set forth in Sections 11.08 and 11.10 hereof).

          The Original Issue Discount of the Securities will continue to accrue
whether or not Contingent Cash Interest payments are made.

          SECTION 13.02  Payment of Contingent Cash Interest; Contingent Cash
Interest Rights Preserved. If payable, Contingent Cash Interest shall be paid on
the last day of the applicable Semiannual Period (in each case, a "Contingent
Cash Interest Payment Date") or, if the Company pays a Regular Cash Dividend on
the Common Stock during a Semiannual Period, on the payment date for the related
Common Stock dividend. Contingent Cash Interest payments on any Security that
are payable, and are punctually paid or duly provided for, on any Contingent
Cash Interest Payment Date shall be paid to the Person who is the holder of that
Security on the 15th day preceding the last day of such Semiannual Period (the
"Contingent Cash Interest Record Date") or, if the company pays regular cash
dividends on the Common Stock during one quarter within such Semiannual Period,
the Common Stock Record Date. Each payment of Contingent Cash Interest on any
Security shall be paid (A) if such Security is held in the form of a Global
Note, in the same-day funds by transfer to an account maintained by the payee
located inside the United States, or (B) if such Security is held in the form of
a Certificated Note, by check, mailed to the address of such Holder as set forth
in the Security Register. In the case of a Global Note, interest payable on any
Contingent Cash Interest Payment date will be paid to the Depositary for the
purpose of permitting DTC to credit the interest received by it in respect of
such Global Note to the accounts of the beneficial owners thereof. If the
Company only pays a Regular Cash Dividend on the Common Stock during one quarter
within such Semiannual Period, the remaining Contingent Cash Interest payments
will accrue and be payable as of the 15th day preceding the last day of the
applicable Semiannual Period.

          Upon determination that Holders of Securities will be entitled to
receive Contingent Cash Interest during a Semiannual Period, prior to the start
of such Semiannual Period, the Company will issue a press release and publish
such information on its website as soon as practicable.

          SECTION 13.03  Bid Calculation Agent. The Bid Calculation Agent shall
solicit bids from securities dealers which the Company indicates that it
believes are willing to bid for the Securities. The Company initially appoints
the Trustee to act as the Bid Calculation

                                       65

Agent. The Company may change the Bid Calculation Agent at its discretion;
provided, however, the Bid Calculation Agent may not be an Affiliate of the
Company.

                                   TAX MATTERS

          SECTION 13A.01 Tax Treatment. The parties hereto hereby agree, and
each Holder and any beneficial holder of a Security by its purchase of a
Security hereby agrees (in the absence of administrative pronouncement or
judicial ruling to the contrary):

          (a) to treat the Securities as indebtedness of the Company for all
     United States federal income tax purposes;

          (b) to treat the Securities as debt instruments that are subject to
     U.S. Treasury Regulation section 1.1275-4(b); and

          (c) to treat any payment to and receipt by a Holder of Common Stock
     upon conversion of a Security, or upon a purchase by the Company at the
     option of the Holder of a Security where the Company elects to pay in
     Common Stock, as a contingent payment under U.S. Treasury Regulation
     section 1.1275-4(b).

          SECTION 13A.02 Comparable Yield and Projected Payment Schedule. Solely
for purposes of applying U.S. Treasury Regulation section 1.1275-4 to the Notes:

          (a)  for United States Federal income tax purposes, the Company shall
               accrue interest with respect to outstanding Securities as
               original issue discount according to the "noncontingent bond
               method," as set forth in U.S. Treasury Regulation section
               1.1275-4(b) using a comparable yield of 6.90%, compounded
               semiannually, and the projected payment schedule attached as
               Annex 1 to this Indenture;

          (b)  the Company shall file with the Trustee promptly at the end of
               each calendar year (i) a written notice specifying the amount of
               original issue discount for United States federal income tax
               purposes (including daily rates and accrual periods) accrued on
               outstanding Securities as of the end of such year and (ii) such
               other specific information relating to such original issue
               discount that the Company determines to be relevant under the
               Internal Revenue Code of 1986, as amended from time to time,
               including the amount of any adjustment made under the
               noncontingent bond method to account for the amount of any
               difference between the amount of an actual payment and the amount
               of a projected payment; and

          (c)  the Company acknowledges and agrees, and each Holder and any
               beneficial holder of a Security, by its purchase of a Security
               shall be deemed to acknowledge and agree, that (i) the comparable
               yield and the projected payment schedule are determined on the
               basis of an assumption of linear growth of stock price and a
               constant growth in dividend yield, (ii) the comparable yield and
               the projected payment schedule are not

                                       66

               determined for any purpose other than for the purpose of applying
               U.S. Treasury Regulation section 1.1275-4(b)(4) to the Security
               and (iii) the comparable yield and the projected payment schedule
               do not constitute a projection or representation regarding the
               actual amounts payable on the Securities.

*    The comparable yield and the schedule of projected payments are determined
on the basis of an assumption of linear growth of the stock price and a constant
growth in dividend yield and are not determined for any purpose other than for
the determination of interest accruals and adjustments thereof in respect of the
Securities for United States federal income tax purposes. The comparable yield
and the schedule of projected payments do not constitute a projection or
representation regarding the amounts payable on Securities.

                    [FORM OF REVERSE SIDE OF ALL SECURITIES]

                        Senior Convertible Notes due 2032

1.   Interest.

     The Company promises to pay interest in cash on the Principal Amount at
Maturity of this Note at the rate per annum of 1.425% from the Issue Date, or
from the most recent date to which interest has been paid or provided for, until
May 14, 2007. During such period, the Company will pay cash interest
semiannually in arrears on May 14 and November 14 of each year (each an
"Interest Payment Date") to Holders of record at the close of business on each
April 29 and October 30 (whether or not a business day) (each a "Regular Record
Date") immediately preceding such Interest Payment Date. Cash interest on the
Securities will accrue from the most recent date to which interest has been paid
or duly provided or, if no interest has been paid, from the Issue Date. Cash
interest will be computed on the basis of a 360-day year of twelve 30-day
months.

     After May 14, 2007, this Security shall not bear interest, except as
specified in this paragraph or in paragraph 11 hereof. If the Principal Amount
at Maturity hereof or any portion of such Principal Amount at Maturity is not
paid when due (whether upon acceleration pursuant to Section 6.02 of the
Indenture, upon the date set for payment of the Redemption Price pursuant to
paragraph 6 hereof, upon the date set for payment of the Purchase Price or
Change in Control Purchase Price pursuant to paragraph 7 hereof or upon the
Stated Maturity of this Security) or if installments of cash interest are not
paid when due in accordance with paragraph 11 hereof, then in each such case the
overdue amount shall, to the extent permitted by law, bear interest at the rate
of 3% per annum, compounded semiannually, which interest shall accrue from the
date such overdue amount was originally due to the date payment of such amount,
including interest thereon, has been made or duly provided for. All such
interest shall be payable on demand. The accrual of such interest on overdue
amounts shall be in lieu of, and not in addition to, the continued accrual of
Original Issue Discount or cash interest.

     Original Issue Discount (the difference between the Issue Price and the
Principal Amount at Maturity of the Security), in the period during which a
Security remains outstanding, shall accrue at 3.00% per annum, on a semiannual
bond equivalent basis using a 360-day year composed of twelve 30-day months,
from the Issue Date of this Security.

2.   Method of Payment.

     Subject to the terms and conditions of the Indenture, the Company will
make payments in respect of Redemption Prices, Purchase Prices, Change in
Control Purchase Prices and at Stated Maturity to Holders who surrender
Securities to a Paying Agent to collect such payments in respect of the
Securities. In addition, the Company will pay cash interest from the Issue Date
until May 14, 2007, as more fully described in paragraph 1 hereof. The Company
will pay any cash amounts in money of the United States that at the time of
payment is legal tender for

                                     A-1-4

<PAGE>

payment of public and private debts. However, the Company may make such cash
payments by check payable in such money.

3.   Paying Agent, Conversion Agent, Registrar and Bid Calculation Agent.

     Initially, JPMorgan Chase Bank, a New York banking corporation chartered
trust company (the "Trustee"), will act as Paying Agent, Conversion Agent,
Registrar and Bid Calculation Agent. The Company may appoint and change any
Paying Agent, Conversion Agent, Registrar or co-registrar and Bid Calculation
Agent without notice, other than notice to the Trustee except that the Company
will maintain at least one Paying Agent in the State of New York, City of New
York, Borough of Manhattan, which shall initially be an office or agency of the
Trustee. The Company or any of its Subsidiaries or any of their Affiliates may
act as Paying Agent, Conversion Agent, Registrar or co-registrar. None of the
Company, any of its Subsidiaries or any of their Affiliates shall act as Bid
Calculation Agent.

4.   Indenture.

     The Company issued the Securities pursuant to an Indenture dated as of
May 14, 2002 (the "Indenture"), between the Company and the Trustee. The terms
of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as in effect from
time to time (the "TIA"). Capitalized terms used herein and not defined herein
have the meanings ascribed thereto in the Indenture. The Securities are subject
to all such terms, and Securityholders are referred to the Indenture and the TIA
for a statement of those terms.

     The Securities are general unsecured and unsubordinated obligations, of
the Company, limited to $368,500,000 aggregate Principal Amount at Maturity
(subject to Section 2.07 of the Indenture). The Indenture does not limit other
indebtedness of the Company, secured or unsecured.

5.   Contingent Cash Interest.

     Subject to the conditions of the Indenture and the accrual and record
date provisions specified in this paragraph 5, the Company shall pay Contingent
Cash Interest to the Securityholders during any six-month period (a "Contingent
Cash Interest Period") from May 14 to November 14 and from November 14 to May
14, with the initial six-month period commencing after May 14, 2007, if the
average Securities Market Price for the Five-Trading-Day Measurement Period with
respect to such Contingent Cash Interest period equals 120% or more of the sum
of the Issue Price of a Security, Original Issue Discount and cash interest, if
any, accrued thereon to the day immediately preceding the first day of the
relevant Contingent Interest Period.

     Contingent Cash Interest, if any, will accrue and be payable to holders
of this Security as of the Contingent Cash Interest Record Date or a Common
Stock Record Date, as applicable. Original Issue Discount will continue to
accrue at 3% whether or not Contingent Cash Interest is paid.

                                     A-1-5

<PAGE>

     The amount of Contingent Cash Interest payable per $1,000 Principal Amount
at Maturity hereof in respect of any quarterly period of the applicable
Contingent Cash Interest Period shall equal the greater of (x) $0.105 and (y)
the sum of all Regular Cash Dividends paid by the Company per share of Common
Stock during that three-month period of the applicable Contingent Cash Interest
Period, in each case, multiplied by the number of shares of Common Stock into
which $1,000 Principal Amount at Maturity hereof is convertible pursuant to
paragraph 9 hereof as of the accrual date for such Contingent Cash Interest.

     Upon determination that Securityholders will be entitled to receive
Contingent Cash Interest during a Contingent Cash Interest Period, the Company
shall issue a press release and publish such information on its web site on the
World Wide Web as soon as practicable.

6.   Redemption at the Option of the Company.

     No sinking fund is provided for the Securities. The Securities are
redeemable as a whole, or from time to time in part, at any time at the option
of the Company in accordance with the Indenture at the Redemption Prices set
forth below, provided that the Securities are not redeemable prior to May 14,
2007.

     The table below shows Redemption Prices of a Security per $1,000
Principal Amount at Maturity on the dates shown below and at Stated Maturity,
which prices reflect accrued Original Issue Discount calculated to each such
date. The Redemption Price of a Security redeemed between such dates shall
include an additional amount reflecting the additional Original Issue Discount
accrued since the immediately preceding date in the table to, but not including,
the Redemption Date and any accrued and unpaid cash interest.

equals the quotient of:

        .   the Issue Price and accrued Original Issue Discount or accrued
            cash interest to that day, divided by

        .   the number of shares of Common Stock issuable upon conversion of

Services, a division of the McGraw-Hill Companies Inc. and its successors
("Standard & Poor's) is BB+ or lower, or (b) the Securities are no longer rated
by either or both of Moody's or Standard & Poor's, or (c) either or both of

has not been satisfied, in the event that the Company declares a dividend or
distribution described in Section 11.07 of the Indenture, or a dividend or a
distribution described in Section 11.08 of the Indenture and, in the case of a
dividend or distribution described in Section 11.08 of the Indenture, the fair
market value, per share, of such dividend or distribution per share of Common
Stock, as determined in the Indenture, exceeds 15% of the Sale Price of the
Common Stock on the Business Day immediately preceding the date of declaration
for such dividend or distribution, the Securities may be surrendered for
conversion beginning on the date the Company gives notice to the Holders of such
right, which shall not be less than 20 days prior to the Ex-Dividend Time for
such dividend or distribution, and Securities may be surrendered for conversion
at any time thereafter until the close of business on the Business Day prior to
the Ex-Dividend Time or until the Company announces that such dividend or
distribution will not take place.

       Conversion Upon Occurrence of Certain Corporate Transactions. Subject to
the provisions of this paragraph 9 and notwithstanding the fact that any other
condition described herein to conversion has not been satisfied, in the event
the Company is a party to a consolidation, merger or binding share exchange
pursuant to which the Common Stock would be converted into cash, securities or
other property as set forth in Section 11.14 of the Indenture, the Securities
may be surrendered for conversion at any time from and after the date which is
15 days prior to the date announced by the Company as the anticipated effective
time until 15 days after the actual effective date of such transaction, and at
the effective time of such transaction the right to convert a Security into
Common Stock will be deemed to have changed into a right to convert it into the
kind and amount of cash, securities or other property which the holder would
have received if the holder had converted its Security immediately prior to the
transaction.

       A Security in respect of which a Holder has delivered a Purchase Notice
or Change in Control Purchase Notice exercising the option of such Holder to
require the Company to purchase such Security may be converted only if such
notice of exercise is withdrawn in accordance with the terms of the Indenture.

       The initial Conversion Rate is 17.763 shares of Common Stock per $1,000
Principal Amount at Maturity, subject to adjustment in the case of certain
events described in the Indenture. The Company will deliver cash or a check in
lieu of any fractional share of Common Stock. The ability to surrender
Securities for conversion will expire at the close of business on May 14, 2032.

       In the event the Company exercises its option pursuant to Section 10.01
of the Indenture to have interest in lieu of Original Issue Discount or cash
interest accrue on the Security following a Tax Event, the Holder will be
entitled on conversion to receive the same number of

                                     A-1-10

<PAGE>

shares of Common Stock such Holder would have received if the Company had not
exercised such option.

       Accrued and unpaid interest in lieu of Original Issue Discount and cash
interest, including Contingent Cash Interest, will not be paid on Securities
that are converted following a Tax Event provided, however that Securities
surrendered for conversion during the period, in the case of interest in lieu of
Original Issue Discount, from the close of business on any Regular Record Date
next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date, shall be entitled to receive such interest, in lieu of
Original Issue Discount, payable on such Securities on the corresponding
Interest Payment Date and (except Securities with respect to which the Company
has mailed a notice of redemption) Securities surrendered for conversion during
such periods must be accompanied by payment of an amount equal to the interest
in lieu of Original Issue Discount with respect thereto that the registered
Holder is to receive.

       To convert a Security, a Holder must (a) complete and manually sign the
conversion notice (or complete and manually sign a facsimile of such notice) and
deliver such notice to the Conversion Agent, (b) surrender the Security to the
Conversion Agent, (c) furnish appropriate endorsements and transfer documents if
required by the Conversion Agent, the Company or the Trustee and (d) pay any
transfer or similar taxes, if required.

       A Holder may convert a portion of a Security if the Principal Amount at
Maturity of such portion is $1,000 or an integral multiple of $1,000. No payment
or adjustment will be made for dividends on the Common Stock except as provided
in the Indenture. On conversion of a Security, accrued Original Issue Discount
and any accrued and unpaid cash interest (or interest if the Company has
exercised its option provided for in paragraph 11 hereof), including Contingent
Cash Interest, attributable to the period from the Issue Date (or, if the
Company has exercised the option referred to in paragraph 11 hereof, the later
of (x) the date of such exercise and (y) the date on which interest was last
paid) through the Conversion Date shall not be cancelled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the Holder thereof
through the delivery of the Common Stock (together with the cash payment, if
any, in lieu of fractional shares) in exchange for the Security being converted
pursuant to the terms hereof; and the fair market value of such shares of Common
Stock (together with any such cash payment in lieu of fractional shares) shall
be treated as issued, to the extent thereof, first in exchange for the Original
Issue Discount and any accrued and unpaid cash interest (or interest, if the
Company has exercised its option provided for in paragraph 11 hereof), including
Contingent Cash Interest, accrued through the Conversion Date, and the balance,
if any, of such fair market value of such Common Stock (and any such cash
payment) shall be treated as issued in exchange for the Issue Price of the
Security being converted pursuant to the provisions hereof.

       The Conversion Rate will be adjusted in accordance with Article 11 of the
Indenture for dividends or distributions on Common Stock payable in Common Stock
or other Capital Stock; subdivisions, combinations or certain reclassifications
of Common Stock; distributions to all holders of Common Stock of certain rights
to purchase Common Stock for a period expiring within 60 days of the Issue Date
at less than the Sale Price of the Common Stock at the Time of Determination;
and distributions to such holders of assets or debt securities of the Company or
certain rights to purchase securities of the Company (excluding certain cash
dividends or

                                     A-1-11

<PAGE>

distributions) and certain rights pursuant to shareholder rights plans. The
Company from time to time may voluntarily increase the Conversion Rate.

       If the Company is a party to a consolidation, merger or binding share
exchange or a transfer of all or substantially all of its assets, or upon
certain distributions described in the Indenture, the right to convert a
Security into Common Stock may be changed into a right to convert it into
securities, cash or other assets of the Company or another person.

10.    [INTENTIONALLY OMITTED.]

11.    Tax Event.

       (a) From and after (i) the date (the "Tax Event Date") of the occurrence
of a Tax Event and (ii) the date the Company exercises the option provided for
in this paragraph 11, whichever is later (the "Option Exercise Date"), at the
option of the Company, interest in lieu of future Original Issue Discount shall
accrue at the rate of 3% per annum on a principal amount per Note (the "Restated
Principal Amount") equal to the Issue Price plus Original Issue Discount accrued
through the Option Exercise Date and shall be payable semiannually on May 14 and
November 14 of each year (each an "Interest Payment Date") to Holders of record
at the close of business on the April 29 and October 30, respectively, (each a
"Regular Record Date") immediately preceding such Interest Payment Date.
Interest will be computed on a semiannual bond equivalent basis using a 360-day
year comprised of twelve 30-day months and will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from the
Option Exercise Date.

       (b) Interest on any Security that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the person in
whose name that Security is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Company maintained
for such purpose. Each installment of interest on any Security shall be paid in
same-day funds by transfer to an account maintained by the payee located inside
the United States.

12.    Defaulted Interest.

       Except as otherwise specified with respect to the Securities, any
Defaulted Interest on any Security shall forthwith cease to be payable to the
registered Holder thereof on the relevant Regular Record Date or accrual date,
as the case may be, and such Defaulted Interest shall be paid by the Company as
provided for in Section 12.02 of the Indenture.

13.    Denominations; Transfer; Exchange.

       The Securities are in fully registered form, without coupons, in
denominations of $1,000 of Principal Amount at Maturity and integral multiples
of $1,000. A Holder may transfer or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Registrar need not transfer
or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or any Securities in respect of which a

                                     A-1-12

<PAGE>

Purchase Notice or Change in Control Purchase Notice has been given and not
withdrawn (except, in the case of a Security to be purchased in part, the
portion of the Security not to be purchased) or any Securities for a period of
15 days before the mailing of a notice of redemption of Securities to be
redeemed.

14.    Persons Deemed Owners.

       The registered Holder of this Security may be treated as the owner of
this Security for all purposes.

15.    Unclaimed Money or Securities.

       The Trustee and the Paying Agent shall return to the Company upon written
request any money or securities held by them for the payment of any amount with
respect to the Securities that remains unclaimed for two years, subject to
applicable unclaimed property laws. After return to the Company, Holders
entitled to the money or securities must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another
person.

16.    Amendment; Waiver.

       Subject to certain exceptions set forth in the Indenture, (a) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate Principal Amount at Maturity of the
Securities at the time outstanding and (b) certain Defaults may be waived with
the written consent of the Holders of a majority in aggregate Principal Amount
at Maturity of the Securities at the time outstanding. Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 or Section 11.14 of the Indenture, to secure the Company's
obligations under this Security or to add to the Company's covenants for the
benefit of the Securityholders or to surrender any right or power conferred, to
comply with any requirement of the SEC in connection with the qualification of
the Indenture under the TIA, or as necessary in connection with the registration
of the Securities under the Securities Act or to make any change that does not
adversely affect the rights of any Holders.

17.    Defaults and Remedies.

       Under the Indenture, Events of Default include (a) default in payment of
interest when due under the Securities and such default continues for 30 days;
(b) default in payment of the Principal Amount at Maturity (or, if the
Securities have been converted to semiannual coupon notes following a Tax Event,
the Restated Principal Amount), Issue Price plus accrued Original Issue Discount
or cash interest, Redemption Price, Purchase Price or Change in Control Purchase
Price, as the case may be, in respect of the Securities when the same becomes
due and payable; (c) failure by the Company to comply with other agreements in
the Indenture or the Securities, subject to notice and lapse of time; (d)
default in the payment of any principal when due or resulting in acceleration of
other indebtedness of the Company for borrowed money where the aggregate
principal amount with respect to which the default or acceleration has occurred
exceeds $10,000,000, and such acceleration has not been rescinded or annulled
within a period

                                     A-1-13

<PAGE>

of 10 days after receipt by the Company of a Notice of Default, subject to
notice and lapse of time; and (e) certain events of bankruptcy or insolvency. If
an Event of Default occurs and is continuing, the Trustee, or the Holders of at
least 25% in aggregate Principal Amount at Maturity of the Securities at the
time outstanding, may declare all the Securities to be due and payable
immediately. Certain events of bankruptcy or insolvency are Events of Default
which will result in the Securities becoming due and payable immediately upon
the occurrence of such Events of Default.

       Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives indemnity or security reasonably satisfactory
to it. Subject to certain limitations, Holders of a majority in aggregate
Principal Amount at Maturity of the Securities at the time outstanding may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default (except a Default
in payment of amounts specified in clause (a) or (b) above) if it determines
that withholding notice is in their interests.

18.    Trustee Dealings with the Company.

       Subject to certain limitations imposed by the TIA, if applicable, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

19.    No Recourse Against Others.

       A director, officer, employee, agent, representative, stockholder or
equity holder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.

20.    Authentication.

       This Security shall not be valid until an authorized signatory of the
Trustee manually signs the Trustee's Certificate of Authentication on the other
side of this Security.

21.    Abbreviations.

       Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with right of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors

       We hereby confirm that:

              (i)   we are an "accredited investor" within the meaning of Rule
       501(a)(1), (2) or (3) under the Securities Act of 1933, as amended (the
       "Securities Act"), or an entity in which all of the equity owners are
       accredited investors within the meaning of Rule 501(a)(1), (2) or (3)
       under the Securities Act (an "Institutional Accredited Investor");

              (ii)  the purchase of Securities by us is for our own account or
       for the account of one or more other Institutional Accredited Investors
       or as fiduciary for the account of one or more trusts, each of which is
       an "accredited investor" within the meaning of Rule 501(a)(7) under the
       Securities Act and for each of which we exercise sole investment
       discretion or (B) we are a "bank," within the meaning of Section 3(a)(2)
       of the Securities Act, or a "savings and loan association" or other
       institution described in Section 3(a)(5)(A) of the Securities Act that is

       institutions for which we exercise sole investment discretion;

              (iii) we will acquire Securities having a minimum principal amount

              (iv) we have such knowledge and experience in financial and
       business matters that we are capable of evaluating the merits and risks
       of purchasing Securities; and

              (v)  we are not acquiring Securities with a view to distribution
       thereof or with any present intention of offering or selling Securities
       or the Common Stock issuable upon conversion thereof, except as permitted
       below; provided that the disposition of our property and property of any
       accounts for which we are acting as fiduciary shall remain at all times
       within our control.

       We understand that the Securities were originally offered and sold in a
transaction not involving any public offering within the United States within
the meaning of the Securities Act and that the Securities and the Common Stock
issuable upon conversion thereof (the Securities and such Common Stock
hereinafter referred to as the "Securities") have not been registered under the
Securities Act, and we agree, on our own behalf and on behalf of each account
for which we acquire any Securities, that if in the future we decide to resell
or otherwise transfer such Securities prior to the date (the "Resale Restriction
Termination Date") which is two years after the later of the last day the
Securities of this issue were issued and the last date on which the Company or
an affiliate of the Company was the owner of the Security, such Securities may
be resold or otherwise transferred only (i) to Horace Mann Educators Corporation
or any subsidiary thereof, or (ii) for as long as the Securities are eligible
for resale pursuant to Rule 144A, to a person it reasonably believes is a
"qualified institutional buyer" (as defined in Rule 144A under the Securities
Act) that purchases for its own account or for the account of a qualified
institutional buyer to which notice is given that the transfer is being made in
reliance on Rule 144A, or (iii) to an Institutional Accredited Investor that is
acquiring the Security for its own account, or for the account of such
Institutional Accredited Investor for investment purposes and not with a view
to, or for offer or sale in connection with, any distribution in violation of
the Securities Act, or (iv) pursuant to another available exemption from
registration under the Securities Act (if applicable), or (v) pursuant to a
registration statement which has been declared effective under the Securities
Act and, in each case, in accordance with any applicable securities laws of any
state of the United States or any other applicable jurisdiction and in
accordance with the legends set forth on the Securities. We further agree to
provide any person purchasing any of the Securities from us other than pursuant
to clause (v) above a notice advising such purchaser that resales of such
securities are restricted as stated herein. We understand that the trustee or
the transfer agent, as the case may be, for the Securities will not be required
to accept for registration of transfer any Securities pursuant to (iii) or (iv)
above except upon presentation of evidence satisfactory to the Company that the
foregoing restrictions on transfer have been complied with. We further
understand that any Securities will be in the form of definitive physical
certificates and that such certificates will bear a legend reflecting the
substance of this paragraph other than certificates representing Securities
transferred pursuant to clause (v) above.

       We acknowledge that the Company, others and you will rely upon our
confirmations, acknowledgments and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.
