     Section 1.03 Incorporation by Reference of Trust Indenture Act. Whenever
this Indenture refers to a provision of the TIA, the provision is incorporated
by reference in and made a part of this Indenture. All TIA terms used in this
Indenture that are defined by the TIA, defined by TIA reference to another
statute or defined by SEC rule have the meanings assigned to them by such
definitions.

     Section 1.04 Rules of Construction.

          (1) a term has the meaning assigned to it;

          (2) an accounting term not otherwise defined has the meaning assigned
     to it and shall be construed in accordance with GAAP;

          (3) "OR" is not exclusive;

                                       6

          (4) "INCLUDING" means including, without limitation;

          (5) words in the singular include the plural, and words in the plural
     include the singular;

          (6) all references to $, dollars, cash payments or money refer to
     United States currency; and

          (7) all references to payments of interest on the Securities shall
     include Additional Amounts, if any, and Liquidated Damages, if any, payable
     in accordance with the terms of the Registration Rights Agreement.

     Section 1.05 Acts of Holders. 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 of substantially similar tenor signed by such Holders in Person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and 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 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.

          (a) The fact and date of the execution by any Person of any such
     instrument or writing may be proved by the affidavit of a witness of such
     execution or by a certificate of a notary public or other officer
     authorized by law to take acknowledgments of deeds, certifying that the
     individual signing such instrument or writing acknowledged to such officer
     the execution thereof. Where 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, or the authority of the Person executing the same, may also be
     proved in any other manner which the Trustee deems sufficient.

          (b) The ownership of Securities shall be proved by the register for
     the Securities.

          (c) 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, the Company or the Conversion Agent in reliance thereon, whether
     or not notation of such action is made upon such Security.

          (d) 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 board resolution, fix in advance a
     record date for the determination of Holders entitled to give such request,
     demand, authorization, direction,

                                       7

     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
     Act, and for that purpose the outstanding Securities shall be computed as
     of such record date; provided that no such authorization, agreement or
     consent by the Holders on such record date shall be deemed effective unless
     it shall become effective pursuant to the provisions of this Indenture not
     later than six months after the record date.

                                   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 set forth in the Form of
Security attached hereto as Exhibit A, which is 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. Except as otherwise
expressly permitted in this Indenture, all Securities shall be identical in all
respects. Notwithstanding any differences among them, all Securities issued
under this Indenture shall vote and consent together on all matters as one
class.

          (a) Global Securities. Securities offered and sold to qualified
     institutional buyers as defined in Rule 144A ("QIBS") in reliance on Rule
     144A shall be issued initially in the form of one or more permanent Global
     Securities, which shall be deposited with or on behalf of The Depository
     Trust Company ("DTC") and registered in the name of Cede & Co., as nominee
     of DTC (Cede & Co., DTC, or any successors thereto being hereinafter
     referred to as the "DEPOSITARY"), duly executed by the Company and
     authenticated by the Trustee as hereinafter provided. The aggregate
     principal amount of the 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) 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 of
     outstanding Securities from time to time endorsed thereon and that the
     aggregate principal amount of outstanding Securities represented thereby
     may from time to time be reduced or increased, as appropriate, to reflect
     exchanges, redemptions, repurchases and conversions.

     Any adjustment of the aggregate principal amount of a Global Security to
reflect the amount of any increase or decrease in the amount of outstanding
Securities represented thereby shall be made by the Trustee in accordance with
instructions given by the Holder thereof as

                                       8

required by Section 2.12 hereof and shall be made on the records of the Trustee
and the Depositary.

          (c) Book-Entry Provisions. This Section 2.01(c) 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(c), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depositary, (b) shall
be delivered by the Trustee to the Depositary or pursuant to the Depositary's
instructions and (c) shall bear a legend substantially to the effect of the
global note legend set forth in the Form of Security attached hereto as Exhibit
A.

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

     If an Officer whose signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security, the Security shall be valid
nevertheless.

     At any time after the execution and delivery of this Indenture, the Company
may deliver Securities executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and deliver such Securities.

     A Security shall not be valid until an authorized signatory of the Trustee
manually signs the certificate of authentication on the Security. The signature
shall be conclusive evidence that the Security has been duly authenticated under
this Indenture.

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

     The aggregate principal amount of Notes which may be authenticated and
delivered under this Indenture is unlimited. The Company may, without the
consent of the holders of Notes, issue additional Notes (the "ADDITIONAL NOTES")
from time to time in the future with the same terms and the same CUSIP number as
the Notes originally issued under this Indenture (the "INITIAL NOTES") in an
unlimited principal amount, provided that such Additional Notes must be part of
the same issue as the Initial Notes for United States federal income tax
purposes. The Initial Notes and any such Additional Notes will constitute a
single series of debt securities, and in circumstances in which this Indenture
provides for the holders of Notes to vote or take any action, the holders of
Initial Notes and the holders of any such Additional Notes will vote or take
that action as a single class.

     The Trustee shall act as the initial authenticating agent. Thereafter, the
Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.

                                       9

An authenticating agent shall have the same rights as the Registrar, Paying
Agent or Conversion Agent to deal with the Company or an Affiliate of the
Company.

     Section 2.03 Registrar, Paying Agent and Conversion 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 repurchase, redemption or payment ("PAYING
AGENT"), an office or agency where Securities may be presented for conversion
("CONVERSION AGENT") and an office or agency where notices to or upon the
Company in respect of the Securities and this Indenture may be served. The
Registrar shall keep a register of the Securities and of their transfer,
exchange, repurchase, redemption and conversion. 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. The term Conversion
Agent includes any additional conversion agent, including any named pursuant to
Section 4.05.

     The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-registrar not a party to this
Indenture, which shall incorporate the terms of the TIA. The agreement shall
implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee of the name and address of any such agent. If
the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the
Trustee shall act as such and shall be entitled to appropriate compensation
therefor pursuant to Section 7.07. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Registrar, Paying Agent,
Conversion Agent or co-registrar.

     The Company initially appoints the Trustee as Registrar, Conversion Agent
and Paying Agent in connection with the Securities, custodian for the Depositary
with respect to the Global Securities, and each office or agency of the Trustee
to be such office or agency of the Company for the aforesaid purposes.

     Section 2.04 Paying Agent to Hold Money and Securities in Trust.
Except as otherwise provided herein, on or prior to each due date of payment 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 or, as permitted by this Indenture, a combination thereof, 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 Holders 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 or a
Wholly Owned Subsidiary 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 the Paying Agent. Upon complying with this Section, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

                                       10

     Section 2.05 Holder 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 Holders. If the Trustee is not the Registrar, the Company shall
furnish to the Trustee, in writing at least five Business Days before each
Interest Payment Date, 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 Holders.

     Section 2.06 Transfer and Exchange. (a) Subject to Section 2.12 hereof,
upon surrender for registration of transfer of any Security, together with a
written instrument of transfer satisfactory to the Registrar duly executed by
the Holder or such Holder'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, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denomination or denominations, of a like
aggregate principal amount.

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

     The Company shall not charge a service charge for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
pay all taxes, assessments or other governmental charges that may be imposed in
connection with the transfer or exchange of the Securities from the Holder
requesting such transfer or exchange.

     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 Repurchase Notice or
Fundamental Change Repurchase Notice has been given and not withdrawn by the
Holder thereof in accordance with the terms of this Indenture (except, in the
case of Securities to be repurchased in part, the portion thereof not to be
repurchased).

          (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 and this Section 2.06(b).
     Transfers of a Global Security shall be limited to transfers of such Global
     Security to the Depositary, 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.

                                       11

          (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 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) Except as set forth in the following sentence, Securities that are
     issued upon the transfer, exchange or replacement of Restricted Securities
     shall bear the restrictive legend set forth in the Form of Security
     attached hereto as Exhibit A (the "RESTRICTIVE LEGEND") and be subject to
     the restrictions on transfer set forth therein. If any Restricted
     Securities are tendered for transfer, exchange or replacement or a request
     is made to remove the Restrictive Legend on a Security, the Securities
     issued upon such transfer, exchange or replacement shall bear the
     Restrictive Legend, or the Restrictive Legend shall not be removed, as the
     case may be, unless (i) there is delivered to the Company and the Registrar
     such satisfactory evidence, which may include an Opinion of Counsel, as may
     be reasonably required by the Company and the Registrar, that neither the
     Restrictive Legend nor the restrictions on transfer set forth therein are
     required to ensure that transfers thereof comply with the provisions of
     Rule 144A or Rule 144 under the Securities Act or that such Securities are
     not "restricted securities" within the meaning of Rule 144 under the
     Securities Act or (ii) the Company notifies the Trustee and Registrar of
     the sale of such Security pursuant to a registration statement that is
     effective at the time of such sale. Upon (i) provision of such satisfactory
     evidence, or (ii) notification by the Company to the Trustee and Registrar
     of such sale pursuant to an effective registration statement, the Trustee,
     upon receipt of a Company Order, shall authenticate and deliver a Security
     that does not bear the Restrictive Legend. If the Restrictive Legend is
     removed from the face of a Security and the Security is subsequently held
     by the Company or an Affiliate of the Company, the Restrictive Legend shall
     be reinstated.

     Section 2.07 Replacement Securities. If a mutilated Security is surrendered
to the Registrar or if the Holder of a Security claims that such Security has
been lost, destroyed or stolen, the Company shall issue and the Trustee shall
authenticate a replacement Security if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such
Holder shall furnish an indemnity bond sufficient in the judgment of the Company
and the Trustee to protect the Company, the Trustee, the Paying Agent, the
Registrar and any co-registrar from any loss which any of them may suffer if a
Security is replaced. The Company and the Trustee may charge the Holder for
their expenses in replacing a Security.

     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 repurchased by the
Company pursuant to Article 3 hereof, the Company in its discretion may, instead
of issuing a new Security, pay or repurchase such Security in cash in an amount
equal to its principal amount plus any accrued and unpaid interest thereon.

                                       12

     Upon the issuance of any new Securities under this Section 2.07, 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 2.07 in exchange for any
mutilated Security, or in lieu of any destroyed, lost or stolen Security, shall
constitute an original additional contractual obligation of the Company and any
other obligor upon the Securities, whether or not the mutilated, 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.

     Section 2.08 Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those cancelled
by it, those 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 of the Company holds the Security; provided,
however, that in determining whether the Holders of the requisite principal
amount of Securities have given or concurred in any request, demand,
authorization, direction, notice, consent, waiver or other action hereunder,
Securities owned by the Company or any obligor upon the Securities or any
Affiliate of the Company or such other obligor shall be disregarded and deemed
not to be outstanding, except that, in determining whether the Trustee shall be
protected in relying upon any such request, demand, authorization, direction,
notice, consent, waiver or other action, only Securities which a Trust 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, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

     If the Paying Agent holds, in accordance with this Indenture, on a
Redemption Date, on the Business Day following a Repurchase Date or a
Fundamental Change Repurchase Date, or on Stated Maturity, money sufficient to
pay Securities payable on that date, then on and after such Redemption Date or
Stated Maturity, or on and after the Business Day following the Repurchase Date
or Fundamental Change Repurchase Date, as the case may be, such Securities shall
cease to be outstanding and interest, if any (including Liquidated Damages and
Additional Amounts, if any), on such Securities shall cease to accrue and such
Securities shall cease to be convertible; provided, that if such Securities are
to be redeemed, notice of such redemption has been duly given pursuant to this
Indenture or provision therefor satisfactory to the Trustee has been made.

     If a Security is converted in accordance with Article 10, then on and after
the Conversion Date, such Security shall cease to be outstanding and interest,
if any (including Liquidated Damages and Additional Amounts, if any), shall
cease to accrue on such Security.

                                       13

     Section 2.09 Temporary Securities. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

     Section 2.10 Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment,
conversion or cancellation and shall dispose of such cancelled Securities in its
customary manner. The Company may not issue new Securities to replace Securities
it has redeemed, repurchased, paid or delivered to the Trustee for cancellation
or that any Holder has converted pursuant to Article 10.

     Section 2.11 Persons Deemed Owners. Prior to due presentment of an
outstanding 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 such Security or the payment of any Redemption
Price, Repurchase Price or Fundamental Change Repurchase Price in respect
thereof, and interest thereon (including Liquidated Damages and Additional
Amounts, if any), for the purpose of conversion thereof 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, (A) transfers of a Global Security, in whole
or in part, shall be made only in accordance with Section 2.06 and Section
2.12(a)(i), (B) transfers of a beneficial interest in a Global Security for a
Certificated Security shall comply with Section 2.06 and Section 2.12(a)(iii)
below, and (C) transfers of a Certificated Security shall comply with Section
2.06 and Section 2.12(a)(iv) and (v) below.

          (i) 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; provided that this clause (i) shall
     not prohibit any issuance of a Certificated Security in exchange for a
     Global Security pursuant to clause (iii) below. No transfer of a Security
     to any Person shall be 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(a)(i) 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(a).

          (ii) Restrictions on Transfer of a Beneficial Interest in a Global
     Security for a Certificated Security. Owners of beneficial interests in a
     Global Security will not be entitled to have Securities represented by that
     Global Security registered in their names, will not receive or be entitled
     to receive physical delivery of Certificated Securities,

                                       14

     except as provided below, and will not be considered the owners or
     holders thereof under this Indenture or under the Securities for any
     purpose, including with respect to the giving of any direction, instruction
     or approval to the Trustee.

          (iii) A beneficial interest in a Global Security may not be exchanged
     for a Certificated Security except:

          (A) Certificated Securities shall be issued to all owners of
     beneficial interests in a Global Security in exchange for such interests
     if:

          1) DTC notifies the Company that it is unwilling or unable to continue
     as Depositary for such Global Security or DTC ceases to be a clearing
     agency registered under the Exchange Act, at a time when DTC is required to
     be so registered in order to act as Depositary, and in each case a
     successor Depositary is not appointed by the Company within 90 days of such
     notice;

          2) the Company executes and delivers to the Trustee and Registrar an
     Officers' Certificate stating that the book-entry system through DTC shall
     be discontinued; or

          3) an Event of Default has occurred and is continuing with respect to
     the Securities.

          In connection with the exchange of one or more entire Global
     Securities for Certificated Securities pursuant to this subsection (ii),
     such Global Securities shall be deemed to be surrendered to the Trustee for
     cancellation, and the Company shall execute, and upon Company Order the
     Trustee shall authenticate and deliver, to each beneficial owner identified
     by DTC in exchange for its beneficial interest in such Global Security, an
     equal aggregate principal amount of Certificated Securities of authorized
     denominations.

          (B) The owner of a beneficial interest in a Global Security will be
     entitled to receive a Certificated Security in exchange for such interest
     if an Event of Default has occurred and is continuing.

          Upon receipt by the Registrar of instructions from the Holder of a
     Global Security directing the Registrar to (x) issue one or more
     Certificated Securities in authorized denominations and the amounts
     specified to the owner of a beneficial interest in such Global Security and
     (y) debit or cause to be debited an equivalent amount of beneficial
     interest in such Global Security, subject to the rules and procedures of
     DTC:

          1) the Registrar shall notify the Company and the Trustee of such
     instructions, identifying the owner and amount of such beneficial interest
     in such Global Security;

          2) the Company shall promptly execute and, upon Company Order, the
     Trustee shall authenticate and deliver to such beneficial owner
     Certificated Security(ies)

                                       15

     in authorized denominations and an equivalent amount to such beneficial
     interest in such Global Security; and

          3) the Registrar shall decrease such Global Security by such amount in
     accordance with the foregoing.

          (iv) 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 of Certificated Securities of other authorized
          denominations,

          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
          transfer or exchange:

     (1)  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

     (2)  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 pursuant to clause
          (a), (b) or (c) below, and are accompanied by the following additional
          information and documents, as applicable:

          (a) 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

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

          (c) if such Certificated Securities are being transferred pursuant to
     an exemption from registration, (i) a certification to that effect (in the
     form set forth in the Form of Security attached hereto as Exhibit A, if
     applicable) and (ii) if the Company so requests, an Opinion of Counsel in
     form and substance reasonably satisfactory to it or other evidence in form
     and substance reasonably satisfactory to it as to the compliance with the
     restrictions set forth in the Restrictive Legend.

          (v) 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.

                                       16

     Subject to the occurrence of the circumstances specified in Section
2.12(a)(iii) above, 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:

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

     (II) 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 of the Securities represented by the Global Security, such
     instructions to contain information regarding the Depositary account to be
     credited with such increase,

     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 of Securities represented by the Global Security to be
     increased by the aggregate principal amount 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 in authorized denominations and equal to the principal
     amount of the Certificated Security so cancelled.

          (b) Subject to Section 2.06(f), every Restricted Security, including
     beneficial interests in a Global Security, shall be subject to the
     restrictions on transfer provided in the Restrictive Legend, including the
     delivery of an Opinion of Counsel, if so required. Whenever any
     Certificated Security that is a 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 Restricted
     Security must be accompanied by a certificate in substantially the form set
     forth in the Form of Security attached hereto as Exhibit A, 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
     accept for such registration of transfer or exchange any Security not so
     accompanied by a properly completed certificate.

          (c) The restrictions imposed by the Restrictive 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 under
     the Securities Act (or any successor provision thereto) or, if earlier,
     upon the expiration of the holding period applicable to sales thereof under
     Rule 144(k) under the Securities Act (or any successor provision). The
     Holder of any Security as to which such restrictions on transfer shall have
     expired in accordance with their terms or shall have terminated may
     request, upon a surrender of such Security for exchange to the Registrar in
     accordance with the provisions of this Indenture, the removal of such
     Restrictive Legend in accordance with the provisions of Section 2.06(f).
     The Company shall inform the Trustee of the effective date of any
     registration statement registering the Securities under the Securities Act.
     The Trustee shall not be liable for any

                                       17

     action taken or omitted to be taken by it in good faith in accordance with
     the aforementioned opinion of counsel or registration statement.

          (d) As used in Sections 2.12(b) and (c), the term "transfer"
     encompasses any sale, pledge, transfer, loan, hypothecation, or other
     disposition of any Security.

          (e) The provisions of clauses (i), (ii) and (iii) below shall apply
     only to Global Securities:

          (i) 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 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 Trustee, as Registrar. With regard to
     any Global Security to be exchanged in part, either such Global Security
     shall be so surrendered for exchange or, if the Trustee is acting as
     custodian for the Depositary with respect to such Global Security, the
     principal amount 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.

          (ii) Subject to the provisions of Section 2.12(f) below, the
     registered Holder may grant proxies and otherwise authorize any Person,
     including Agent Members 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.

          (iii) In the event of the occurrence of any of the events specified in
     Section 2.12(a)(iii) above, the Company will promptly make available to the
     Trustee a reasonable supply of Certificated Securities in definitive, fully
     registered form, without interest coupons.

          (f) Neither any members of, or participants in, the Depositary
     (collectively, the "AGENT MEMBERS") nor any other Persons on whose behalf
     Agent Members may act 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 under this Indenture
     and under the Securities. 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.

                                       18

     The Holder of a Global Security may grant proxies and otherwise authorize
     any Person, including Agent Members and Persons that may hold interests
     through Agent Members, to take any action that a Holder is entitled to take
     under this Indenture or the Securities.

     Section 2.13 CUSIP and ISIN Numbers. The Company in issuing the Securities
may use "CUSIP" and "ISIN" numbers (if then generally in use) and, if so, the
Trustee shall use CUSIP and ISIN numbers in notices of redemption as a
convenience to Holders; provided, however, that neither the Company nor the
Trustee shall have any responsibility for any defect in the CUSIP or ISIN number
that appears on any Security, check, advice of payment or redemption notice, and
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 shall
promptly notify the Trustee in the event of any change in the CUSIP or ISIN
numbers.

     Section 2.14 Liquidated Damages Under Registration Rights
Agreement. The terms of the Registration Rights Agreement are hereby
incorporated herein by reference and any Liquidated Damages payable pursuant to
the terms of the Registration Rights Agreement are deemed to be interest for
purposes of this Indenture.

     Section 2.15 Ranking. The Securities will be senior, unsecured
obligations of the Company and will rank equal in right of payment to all of the
Company's existing and future unsecured and unsubordinated indebtedness.

     Section 2.16 Company Determination Final. The Company will be
responsible for making all calculations required under the Securities, unless
otherwise set forth in this Indenture. Such calculations include, but are not
limited to, determinations of the Closing Sale Price of the Common Stock, the
Trading Price of the Securities, the amount of accrued interest (including
Liquidated Damages and Additional Amounts, if any) payable on the Securities and
the Conversion Price of the Securities. The Company shall make all such
calculations in good faith, and, absent manifest error, such calculations will
be final and binding on Holders of Securities. The Company shall provide a
schedule of its calculations to the Trustee, and the Trustee is entitled to rely
upon the accuracy of such calculations without independent verification. The
Trustee will forward such calculations to any Holder upon the request of such
Holder.

                                   ARTICLE 3

                           REDEMPTION AND REPURCHASES

     Section 3.01 Company's Right to Redeem; Notices to Trustee. (a) The
Securities will not be subject to redemption prior to September 1, 2012, except
as otherwise set forth in this Section 3.01. On or after September 1, 2012, the
Company shall have the right to redeem the Securities in whole or in part, at
any time or from time to time, for a cash Redemption Price equal to 100% of the
principal amount of the Securities to be redeemed, plus any accrued and unpaid
interest (including Liquidated Damages and Additional Amounts, if any) thereon
up to, but not including, the Redemption Date (the "REDEMPTION PRICE"). If the
Redemption Date is

                                       19

on a date that is after a Record Date and on or prior to the corresponding
Interest Payment Date, the Company shall pay the related interest (including
Liquidated Damages and Additional Amounts, if any) to the person to whom
principal is payable.

     (b) If, at any time, the Company determines it is necessary to redeem
the Securities in order to preserve the Company's qualification as a real estate
investment trust under the Internal Revenue Code of 1986, as amended ("REIT"),
the Company, upon not less than 30 nor more than 60 days' prior written notice
delivered to the Holders, may redeem all of the Securities then outstanding at
100% principal amount of the Securities, plus accrued and unpaid interest
(including Liquidated Damages and Additional Amounts, if any), to the Redemption
Date. In such case, the Company shall provide the Trustee with an Officer's
Certificate evidencing that the Board of Directors has, in good faith, made the
determination that it is necessary to redeem the Securities in order to preserve
the Company's qualification as a REIT for U.S. federal income tax purposes.

     The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 60 days before the Redemption Date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.

     Section 3.02 Selection of Securities To Be Redeemed. If fewer than
all outstanding Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed by lot, on a pro rata basis or by another method that
complies with applicable legal and securities exchange requirements, if any, and
that the Trustee considers appropriate. The Trustee shall make the selection
from outstanding Securities not previously called for redemption. The Trustee
may select for redemption portions of the principal amount of Securities that
have denominations larger than $1,000. Securities and portions of Securities the
Trustee selects shall be in principal amounts of $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The
Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed.

     If the Trustee selects a portion of a Holder's Securities for partial
redemption and such Holder converts a portion of the same Securities, the
converted portion will be deemed first to be from the portion selected for
redemption.

     Section 3.03 Notice of Redemption. At least 30 days but not more
than 60 days before a Redemption Date, the Company or the Trustee 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;

          (c) the Conversion Rate;

                                       20

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

          (e) that Securities called for redemption may be converted at any time
     before the close of business on the Business Day immediately preceding the
     Redemption Date;

          (f) that Holders who want to convert their Securities must satisfy all
     the requirements set forth herein and in the Securities;

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

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

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

          (j) the CUSIP and ISIN number(s) of the Securities.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense, provided that the Company
makes such request at least three Business Days prior to the date by which such
notice of redemption must be given to Holders in accordance with this Section
3.03, provided further that, in all cases, the text of such notice of redemption
shall be prepared by the Company.

     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 stated in the notice of redemption 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 stated in the notice of redemption.

     Section 3.05 Deposit of Redemption Price. Prior to 10:00 a.m. (New York
City time), on the Redemption Date, the Company shall deposit with the Paying
Agent (or if the Company or a Wholly Owned Subsidiary is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the Redemption Price of all
Securities to be redeemed on that date other than Securities or portions of
Securities called for redemption which 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 10. 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.

          (a) In the event of any redemption in part, the Company will not be
     required to issue, register the transfer of or exchange any Security during
     a period beginning at the

                                       21

     opening of business 15 days before any selection of Securities for
     redemption and ending at the close of business on the earliest date on
     which the relevant notice of redemption is deemed to have been given to all
     Holders of Securities to be so redeemed or, register the transfer of or
     exchange any Security, so selected for redemption, in whole or in part,
     except the unredeemed portion of any Security being redeemed in part.

          (b) 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 to
     the unredeemed portion of the Security surrendered, or in the case of a
     Global Security, the Company shall instruct the Registrar to decrease such
     Global Security by the principal amount of the redeemed portion of the
     Security surrendered.

     Section 3.07 Repurchase of Securities by the Company at Option of
the Holder. (a) General. Securities, in whole or in part (equal to $1,000 or a
integral multiple thereof), shall be repurchased by the Company at the option of
the Holder on September 1, 2012, September 1, 2017 and September 1, 2022 or the
next Business Day following such date to the extent any such date is not a
Business Day (each, a "REPURCHASE DATE"), in U.S. legal tender ("CASH") at 100%
of the principal amount to be repurchased plus any accrued and unpaid interest,
(including Liquidated Damages and Additional Amounts, if any), thereon up to,
but not including, such Repurchase Date (the "REPURCHASE PRICE"). If a
Repurchase Date is on a date that is after the Record Date and on or prior to
the corresponding Interest Payment Date, the Company shall pay the related
interest (including Liquidated Damages and Additional Amounts, if any) to the
person to whom the principal is payable.

     No Securities may be repurchased by the Company at the option of Holders if
there has occurred and is continuing an Event of Default with respect to the
Securities, other than a default in the payment of the Repurchase Price with
respect to the Securities. Repurchases of Securities hereunder shall be made, at
the option of the Holder thereof, upon:

          (i) delivery to the Paying Agent and the Company by the Holder of a
     written notice (or in the case of Global Securities, a notice delivered
     electronically or by other means in accordance with the Depositary's
     customary procedures) of repurchase (a "REPURCHASE NOTICE") during the
     period beginning at any time from the opening of business on the date that
     is 20 Business Days prior to the relevant Repurchase Date until the close
     of business on the second Business Day prior to such Repurchase Date
     stating:

          (A) if the Securities are Certificated Securities the certificate
     number of the Security which the Holder will deliver to be repurchased, if
     any; if the Securities are not Certificated Securities, all information
     required to comply with all DTC procedures,

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

                                       22

          (C) that such Security or portion thereof shall be repurchased by the
     Company as of the Repurchase Date pursuant to the terms and conditions
     specified in the applicable provisions of such Security and this Indenture,
     and

          (ii) delivery of such Security to the Paying Agent at any time after
     delivery of the Repurchase Notice (together with all necessary endorsements
     and compliance by the Holder with all DTC procedures) at the offices of the
     Paying Agent, such delivery being a condition to receipt by the Holder of
     the Repurchase Price therefor; provided, however, that such Repurchase
     Price shall be so paid pursuant to this Section 3.07 only if the Security
     so delivered to the Paying Agent shall conform in all respects to the
     description thereof in the related Repurchase Notice, as determined by the
     Company.

     The Company shall repurchase from the Holder thereof, pursuant to this
Section 3.07, a portion of a Security, if the principal amount of such portion
is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that

this Section 3.07 shall be consummated by the delivery to the Paying Agent of
the consideration to be received by the Holder on the Business Day following the
later of the Repurchase Date or the satisfaction of the foregoing conditions to
such repurchase to be fulfilled by the Holder hereunder. If the Paying Agent
holds money sufficient to pay the Repurchase Price of the Security on such
Business Day in accordance with the terms of this Indenture, then, from and
including the Repurchase Date, interest (including Liquidated Damages and
Additional Amounts, if any) on such Security will cease to accrue and all other
rights of the Holder shall terminate, other than the right to receive the
Repurchase Price upon satisfaction of the foregoing conditions.

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Repurchase Notice contemplated by this Section 3.07(a)
shall have the right to withdraw such Repurchase Notice at any time prior to the
close of business on the second Business Day prior to the Repurchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 3.09. If the Repurchase Notice is withdrawn during such period, the
Company will not be obligated to purchase the related Securities. The Paying
Agent shall promptly notify the Company of the receipt by it of any written
notice of withdrawal of a Repurchase Notice.

          (b) Company Notice. At least 30 days but not more than 60 days before
     a Repurchase Date (the "COMPANY NOTICE DATE"), the Company or the Trustee
     shall mail a notice to Holders setting forth information specified in this
     Section 3.07(b) (the "COMPANY NOTICE").

     Each Company Notice shall include a form of Repurchase Notice to be
completed by a Holder and shall state:

          (i) the Repurchase Price and the Conversion Rate;

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

                                       23

          (iii) that Securities as to which a Repurchase Notice has been given
     may be converted if they are otherwise convertible only in accordance with
     Article 10 hereof and the applicable provisions of the Securities if the
     applicable Repurchase Notice has been withdrawn in accordance with the
     terms of this Indenture;

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

          (v) that the Repurchase Price for any Security as to which a
     Repurchase Notice has been given and not withdrawn will be paid on the
     Business Day following the later of the Repurchase Date and the Holder's
     satisfaction of all applicable conditions;

          (vi) the procedures the Holder must follow to exercise its repurchase
     rights under this Section 3.07 and a brief description of such rights;

          (vii) briefly, the conversion rights, if any, of the Securities;

          (viii) the procedures for withdrawing a Repurchase Notice;

          (ix) that, unless the Company defaults in making payment on Securities
     for which a Repurchase Notice has been submitted, interest, if any
     (including Liquidated Damages and Additional Amounts, if any), on such
     Securities will cease to accrue on and after the Repurchase Date; and

          (x) the CUSIP and ISIN number(s) of the Securities.

     At the Company's request, the Trustee shall give such Company Notice in the
Company's name and at the Company's expense, provided that the Company makes
such request at least three Business Days prior to the date by which such
Company Notice must be given to Holders in accordance with this Section 3.07;
provided further that, in all cases, the text of such Company Notice shall be
prepared by the Company.

          (c) Procedure upon Repurchase. The Company shall deposit cash in
     respect of cash repurchases under this Section 3.07 at the time and in the
     manner as provided in Section 3.10, sufficient to pay the aggregate
     Repurchase Price of all Securities to be repurchased pursuant to this
     Section 3.07.

     Section 3.08 Repurchase of Securities at Option of the Holder Upon
a Fundamental Change.

          (a) If a Fundamental Change occurs prior to September 1, 2012,
     outstanding Securities shall be repurchased by the Company in whole or in
     part (equal to $1,000 or an integral multiple thereof), at the option of
     the Holder thereof, in cash, at the Repurchase Price on the Fundamental
     Change Repurchase Date (the "FUNDAMENTAL CHANGE REPURCHASE PRICE"), as of
     the date that is no earlier than 20 Business Days and no later than 30
     Business Days after the date of the Fundamental Change Notice delivered by
     the Company (the "FUNDAMENTAL CHANGE REPURCHASE DATE"), subject to
     satisfaction by or on behalf of the Holder of the requirements set forth in
     Section 3.08(c). If the

                                       24

     Fundamental Change Repurchase Date is on a date that is after a Record Date
     and on or prior to the corresponding Interest Payment Date, the Company
     will pay the related interest (including Liquidated Damages and Additional
     Amounts, if any) to the person to whom principal is payable. No Securities
     may be repurchased by the Company at the option of Holders upon a
     Fundamental Change if there has occurred and is continuing an Event of
     Default with respect to the Securities, other than a default in payment of
     the Fundamental Change Repurchase Price with respect to the Securities.

     A "FUNDAMENTAL CHANGE" shall be deemed to have occurred at such time after
the Securities are originally issued that any of the following events shall
occur:

          (i) a "person" or "group" (each within the meaning of Section 13(d)(3)
     of the Exchange Act) becomes the direct or indirect "beneficial owner," as
     defined in Rule 13d-3 under the Exchange Act, of shares of Common Stock
     representing more than 50% of the total voting power in the aggregate of
     classes of the Company's Capital Stock entitled to vote generally in the
     election of directors; or

          (ii) the first day on which a majority of the members of the Board of
     Directors does not consist of Continuing Directors; or

          (iii) a consolidation, merger or binding share exchange, or any
     conveyance, transfer, sale, lease or other disposition of all or
     substantially all of the Company's assets to another Person, other than:

          (A) any transaction

               (y) that does not result in any reclassification, conversion,
          exchange or cancellation of outstanding shares of the Company's
          Capital Stock; and

               (z) pursuant to which holders of the Company's Capital Stock
          immediately prior to the transaction have the entitlement to exercise,
          directly or indirectly, 50% or more of the total voting power of all
          shares of Capital Stock entitled to vote generally in election of
          directors of the continuing or surviving or successor Person
          immediately after giving effect to such issuance; or

          (B) any consolidation, merger, share exchange, conveyance, transfer,
     sale, lease or other disposition of assets or similar transaction solely
     for the purpose of changing the Company's jurisdiction of incorporation and
     resulting in a reclassification, conversion or exchange of outstanding
     Common Stock, if at all, solely into common stock, ordinary shares,
     American Depositary Shares or depositary receipts or other certificates
     representing common equity interests of the surviving entity or a direct or
     indirect parent of the surviving corporation; or

          (C) any consolidation or merger with or into any of the Company's
     Subsidiaries, so long as such merger or consolidation is not part of a plan
     or a series of transactions designed to or having the effect of merging or
     consolidating with any other Person;

                                       25

          (iv) a Termination of Trading; or

          (v) the holders of the Company's Capital Stock approve any plan or
     proposal for the liquidation or dissolution of the Company, whether or not
     in compliance with the terms hereof.

     Notwithstanding the foregoing provisions of this Section 3.08, a Holder
will not have the right to require the Company to repurchase its Securities upon
a Fundamental Change described in clause (iii) of the definition of such term if
more than 90% of the consideration in the transaction or transactions consists
of Listed Common Equity immediately following the relevant transaction or
transactions, and, as a result of the transaction or transactions, the
Securities become convertible into that Listed Common Equity (including any
rights attached thereto).

     If the Company desires the Trustee to give the Fundamental Change Notice
required by Section 3.08(b), at least three Business Days before the Fundamental
Change Notice Date, the Company shall deliver an Officers' Certificate to the
Trustee specifying the information required by Section 3.08(b).

          (b) Within 15 days after the occurrence of a Fundamental Change, the
     Company (or the Trustee, as applicable) shall mail a written notice of the
     Fundamental Change (the "FUNDAMENTAL CHANGE NOTICE," the date of such
     mailing, the "FUNDAMENTAL CHANGE NOTICE DATE") by first-class mail to the
     Trustee and to each Holder. Simultaneously with providing such notice, the
     Company will issue a press release and publish the information on its
     website. The Fundamental Change Notice shall include a form of Fundamental
     Change Repurchase Notice to be completed by the Holder and shall state:

          (i) briefly, the nature of the Fundamental Change and the date of such
     Fundamental Change;

          (ii) the date by which the Fundamental Change Repurchase Notice
     pursuant to Section 3.08(c) must be given;

          (iii) the Fundamental Change Repurchase Date;

          (iv) the Fundamental Change Repurchase Price;

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

          (vi) the Conversion Rate and any adjustments thereto;

          (vii) that the Securities as to which a Fundamental Change Repurchase
     Notice has been given may be converted if they are otherwise convertible
     pursuant to Article 10 hereof only if the Fundamental Change Repurchase
     Notice has been withdrawn in accordance with the terms of this Indenture;

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

                                       26

          (ix) that the Fundamental Change Repurchase Price for any Security as
     to which a Fundamental Change Repurchase Notice has been duly given and not
     withdrawn will be paid on the Business Day following the later of the
     Fundamental Change Repurchase Date and the Holder's satisfaction of all
     applicable conditions;

          (x) briefly, the procedures the Holder must follow to exercise rights
     under this Section 3.08;

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

          (xii) the procedures for withdrawing a Fundamental Change Repurchase
     Notice;

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

          (xiv) the CUSIP and ISIN number(s) of the Securities.

     At the Company's request, the Trustee shall give such Fundamental Change
Notice in the Company's name and at the Company's expense, provided that the
Company makes such request at least three Business Days prior to the date by
which such Fundamental Change Notice must be given to Holders in accordance with
this Section 3.08; provided further that, in all cases, the text of such
Fundamental Change Notice shall be prepared by the Company.

          (c) A Holder may exercise its rights specified in Section 3.08(a) upon
     delivery of a written notice of repurchase (a "FUNDAMENTAL CHANGE
     REPURCHASE NOTICE") to the Paying Agent at any time on or prior to the
     close of business on the second Business Day prior to Fundamental Change
     Repurchase Date, stating:

          (i) If the Securities are Certificated Securities, the certificate
     number of the Security which the Holder will deliver to be repurchased; if
     the Securities are not Certificated Securities, all information required to
     comply with all DTC procedures;

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

          (iii) that such Security shall be repurchased pursuant to the terms
     and conditions specified in the applicable provisions of such Security and
     this Indenture.

The delivery of such Security to the Paying Agent with the Fundamental Change
Repurchase Notice (together with all necessary endorsements and compliance by
the Holder with all DTC procedures) at the offices of the Paying Agent shall be
a condition to the receipt by the Holder of the Fundamental Change Repurchase
Price therefor; provided, however, that such Fundamental Change Repurchase Price
shall be so paid pursuant to this Section 3.08 only if the Security so

                                       27

delivered to the Paying Agent shall conform in all material respects to the
description thereof set forth in the related Fundamental Change Repurchase
Notice.

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

     Any repurchase by the Company contemplated pursuant to the provisions of
this Section 3.08 shall be consummated by the delivery of the consideration to
be received by the Holder on the Business Day following the later of the
Fundamental Change Repurchase Date or the satisfaction of the foregoing
conditions to such repurchase to be fulfilled by the Holder hereunder. If the
Paying Agent holds money sufficient to pay the Fundamental Change Repurchase
Price of the Securities which Holders have elected to require the Company to
repurchase on such Business Day in accordance with the terms of this Indenture,
then, from and including the Fundamental Change Repurchase Date, those
Securities will cease to be outstanding and interest (including Liquidated
Damages and Additional Amounts, if any) on the Securities will cease to accrue
and all other rights of the Holders shall terminate, other than the right to
receive the Fundamental Change Repurchase Price upon satisfaction of the
foregoing conditions.

          (d) Procedure upon Repurchase. The Company shall deposit cash, at the
     time and in the manner as provided in Section 3.10, sufficient to pay the
     aggregate Fundamental Change Repurchase Price of all Securities to be
     repurchased pursuant to this Section 3.08.

Notice. Upon receipt by the Paying Agent of the Repurchase Notice or Fundamental
Change Repurchase Notice specified in Section 3.07(a) or Section 3.08(c), as

     Section 3.11 Securities Repurchased in Part. Any Certificated
Security which is to be repurchased only in part shall be surrendered at the
office of the Paying Agent (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing) and the Company shall execute and the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge, a new Security or Securities, of any authorized denomination as

for, the portion of the principal amount of the Security so surrendered which is
not repurchased, or in the case of a Global Security, the Company shall instruct
the Registrar to decrease such Global Security by the principal amount of the
repurchased portion of the Security surrendered.

     Section 3.12 Covenant to Comply with Securities Laws Upon
Repurchase of Securities. When complying with the provisions of Section 3.07 or
3.08 hereof (provided that such offer or repurchase constitutes an "issuer

Company any cash held by the Trustee or the Paying Agent, as applicable, for the
payment of the Repurchase Price or Fundamental Change Repurchase Price, as the
case may be, that remains unclaimed by the Holders for a period of two years;
provided, however, that to the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 3.10 exceeds the aggregate
Repurchase Price or Fundamental Change Repurchase Price, as the case may be, of
the Securities or portions thereof which the Company is obligated to repurchase
as of the Business Day following the Repurchase Date or Fundamental Change

surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 12.02.

     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 United States
of America, 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 owner of Securities or holder or
beneficial owner of shares of Common Stock issued upon conversion thereof, the
Company will promptly furnish or cause to be furnished Rule 144A Information to
such Holder or any beneficial owner of Securities or holder or beneficial owner
of

                                       31

shares of Common Stock, or to a prospective purchaser of any such security
designated by any such Holder or holder, as the case may be, to the extent
required to permit compliance by such Holder or holder with Rule 144A under the
Securities Act in connection with the resale of any such Security, until such
time as the same are no longer "restricted securities" within the meaning of
Rule 144 under the Securities Act. "RULE 144A INFORMATION" shall be such
information as is specified pursuant to Rule 144A(d)(4) under the Securities
Act. Whether a Person is a beneficial owner shall be determined by the Company
to the Company's reasonable satisfaction.

                              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, convey, transfer,
sell or lease all or substantially all of its assets to any Person, or permit
any Person to consolidate with or merge into the Company, unless:

          (a) either the Company is the continuing corporation or the resulting,
     surviving or transferee Person will be a corporation organized and existing
     under the laws of the United States of America, any State thereof or the
     District of Columbia (unless such corporation has expressly assumed, by a
     supplemental indenture, executed and delivered to the Trustee, in form
     reasonably satisfactory to the Trustee, all of the Company's obligations
     under the Securities and this Indenture);

          (b) if as a result of such transaction the Securities become
     exchangeable into common stock or other equity securities issued by a third
     party, such third party assumes or fully and unconditionally guarantees all
     obligations under the Securities and this Indenture;

          (c) immediately after giving effect to such transaction (and treating
     any indebtedness which becomes an obligation of the successor Person, if
     other than the Company, as a result of such transaction as having been
     incurred by the successor Person at the time of such transaction), no Event
     of Default, and no Default shall have occurred and be continuing; and

          (d) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger, conveyance, transfer, sale 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.

     The successor Person formed by such consolidation or into which the Company
is merged or the successor Person to which such conveyance, transfer, sale or
lease is made shall succeed to, and be substituted for, and may exercise every
right and power of, the Company under this Indenture with the same effect as if
such successor Person had been named as the Company herein; and thereafter,
except in the case of a lease of all or substantially all of the

                                       32

Company's assets, the Company shall be discharged from all obligations and
covenants under this Indenture and the Securities. Subject to Section 9.06, the
Company, the Trustee and the successor Person shall enter into a supplemental
indenture to evidence the succession and substitution of such successor Person
and such discharge and release of the Company.

                                    ARTICLE 6

                              DEFAULTS AND REMEDIES

     Section 6.01 Events of Default. Each of the following events shall be an
"EVENT OF DEFAULT":

          (i) the Company defaults in any payment of interest due and payable on
     the Securities (including Liquidated Damages and Additional Amounts, if
     any), and such Default continues for a period of 30 days past the
     applicable due date;

          (ii) the Company defaults in the payment of all or any part of the
     principal amount, Redemption Price, Repurchase Price or Fundamental Change
     Repurchase Price when the same becomes due and payable at its Stated
     Maturity, upon redemption, upon repurchase at the option of a Holder, upon
     a Fundamental Change or any other Repurchase Date, or otherwise;

          (iii) the Company fails to provide a Fundamental Change Notice as
     required in Section 3.08(b);

          (iv) the Company defaults in its obligation to deliver when due the
     Settlement Amount upon conversion of the Securities, together with cash in
     lieu thereof in respect of any fractional shares, required to be delivered
     upon conversion of the Securities;

          (v) the Company fails to perform or observe any covenant in the
     Securities or in this Indenture (other than a failure that is the subject
     of the foregoing clauses (i) or (ii)) for 60 days after receipt by the
     Company of a notice of default from the Trustee or after receipt by the
     Company and the Trustee of a notice of default from the Holders of at least
     25% in principal amount of the outstanding Securities;

          (vi) a failure to pay when due at maturity or a Default that results
     in the acceleration of any indebtedness for borrowed money of the Company
     or its Subsidiaries in an aggregate amount of $15,000,000 or more;

          (vii) the failure by the Company or any of its Subsidiaries to pay
     final judgments aggregating in excess of $15,000,000, which judgments are
     not paid, discharged or stayed for a period of 60 days from the dates such
     judgments are entered; and

          (viii) the Company or any of its Significant Subsidiaries pursuant to
     or within the meaning of any Bankruptcy Law:

          (A) commences a voluntary case;

                                       33

          (B) consents to the entry of an order for relief against it in an
     involuntary case;

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

          (D) makes a general assignment for the benefit of its creditors or
     takes any comparable action under any foreign laws relating to insolvency;
     or

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

          (A) is for relief against the Company or any of its Significant
     Subsidiaries in an involuntary case;

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

          (C) orders the winding up or liquidation of the Company or any of its
     Significant Subsidiaries; or

          (D) grants any similar relief under any foreign laws and in each such
     case the order or decree remains unstayed and in effect for 60 days.

     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

     The term "BANKRUPTCY LAW" means Title 11, United States Code, or any
similar Federal, state or non-U.S. law for the relief of debtors. The term
"CUSTODIAN" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

     The Company shall deliver to the Trustee, as promptly as reasonably
practicable and in any event within 30 days after the occurrence thereof,
written notice in the form of an Officers' Certificate of any Event of Default
and any Default, its status and what action the Company is taking or proposes to
take with respect thereto.

     Section 6.02 Acceleration. Except as provided in Section 11.02, if
an Event of Default (other than an Event of Default specified in Sections
6.01(viii) or 6.01(ix)with respect to the Company) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities then outstanding by notice to the Company and
the Trustee, may declare the principal amount of Securities outstanding plus
accrued and unpaid interest, if any (including Liquidated Damages and Additional
Amounts, if any), on all the outstanding Securities to be immediately due and
payable. Upon such a declaration, such accelerated amount shall be due and
payable immediately. If an Event of Default specified in Sections 6.01(viii) or
6.01(ix) with respect to the Company occurs and is continuing, the principal
amount of Securities outstanding plus accrued and unpaid interest, if any
(including Liquidated Damages and Additional Amounts, if any), on all the
Securities shall,

                                       34

automatically and without any action by the Trustee or any Holder, become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. The Holders of a majority in aggregate principal
amount of the Securities at the time outstanding by notice to the Trustee and
the Company and without notice to any other Holder may rescind any declaration
of acceleration if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of the principal amount plus accrued and unpaid interest, if any
(including Liquidated Damages and Additional Amounts, if any), that have become
due solely as a result of acceleration. 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 principal amount plus accrued and unpaid interest, if any (including
Liquidated Damages and Additional Amounts, if any), 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 it 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 Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

     Section 6.04 Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding by notice
to the Trustee and without notice to any other Holder may waive any past Default
and its consequences except (a) an Event of Default described in Sections
6.01(i) and 6.01(ii), (b) a Default in respect of a covenant that under Section
9.02 cannot be amended without the consent of each Holder, (c) a Default which
constitutes a failure to convert any Security in accordance with the terms of
Article 10 or (d) a Default arising from the Company's failure to repurchase any
Securities when required in accordance with Sections 3.07 and 3.08. 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.

     Section 6.05 Control by Majority. The Holders of a majority in aggregate
principal amount of the Securities at the time outstanding may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. However,
the Trustee may refuse to follow any direction that conflicts with law or this
Indenture or, subject to Section 7.01, that the Trustee determines is unduly
prejudicial to the rights of other Holders or would potentially involve the
Trustee in personal liability. Prior to taking any action hereunder, the Trustee
shall be entitled to indemnification satisfactory to the Trustee in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

     Section 6.06 Limitation on Suits. A Holder may not pursue any remedy with
respect to this Indenture or the Securities, except in the case of a Default due
to the non-payment of principal or interest (including Liquidated Damages and
Additional Amounts, if any), a failure to deliver the Settlement Amount upon
conversion of the Securities, a Default arising from the Company's failure to
repurchase any Securities when required pursuant to the terms of this

                                       35

Indenture or a Default in respect of any covenant that cannot be amended without
the consent of each Holder affected unless:

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

          (b) the Holders of at least 25% in aggregate principal amount of the
     Securities at the time outstanding make a written request, and such Holder
     or Holders shall have offered indemnity satisfactory to the Trustee to
     pursue such remedy;

          (c) the Trustee has not received from the Holders of a majority in
     aggregate principal amount of the Securities at the time outstanding a
     direction inconsistent with such request; and

          (d) the Trustee fails to comply with the request within 60 days after
     receipt of the request and offer of indemnity.

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

     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, Redemption Price, Repurchase Price, Fundamental Change
Repurchase Price or interest, if any (including Liquidated Damages and
Additional Amounts, if any), in respect of the Securities held by such Holder,
on or after the respective due dates expressed in such Holder's Securities or
any Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, and
to convert the Securities in accordance with Article 10, 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 without the consent of such
Holder.

     Section 6.08 Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(i) or 6.01(ii) 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 then due and owing (together with interest on any unpaid
interest, including Liquidated Damages and Additional Amounts, to the extent
lawful) and the amounts provided for in Section 7.07.

     Section 6.09 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Holders allowed in any
judicial proceedings relative to the Company, its creditors or its property and,
unless prohibited by law or applicable regulations, may vote on behalf of the
Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make 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 to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

                                       36

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

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

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

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

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10. At least 15 days before such record date,
the Company shall mail to each Holder and the Trustee 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 omitted by it as Trustee, a court in its discretion may require
the filing by any party litigant 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 of the Securities at the time
outstanding.

     Section 6.12 Waiver of Stay or Extension Laws. The Company (to the extent
it may lawfully do so) shall not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall 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:

                                       37

          (i) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture.

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

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

          (ii) the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust 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.

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

          (e) The Trustee shall not be liable for interest on any money received
     by it.

          (f) Cash or Common Stock held in trust by the Trustee need not be
     segregated from other funds except to the extent required by law.

          (g) No provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur financial liability in the
     performance of any of its duties hereunder or in the exercise of any of its
     rights or powers.

          (h) Every provision of this Indenture relating to the conduct or
     affecting the liability of or affording protection to the Trustee shall be
     subject to the provisions of this Section and to the provisions of the TIA
     and the provisions of this Article 7 shall apply to the Trustee in its role
     as Registrar and Paying Agent.

          (i) The Trustee shall not be deemed to have notice of a Default or an
     Event of Default unless (i) a Trust Officer of the Trustee has received
     written notice thereof from the Company or any Holder referencing the
     Indenture and the Securities and stating that such notice is a notice of
     default or (ii) a Trust Officer shall have actual knowledge thereof.

     Section 7.02 Rights of Trustee. (a) The Trustee may conclusively rely on
any document believed by it to be genuine and to have been signed or presented
by the proper Person. The

                                       38

Trustee need not investigate any fact or matter stated in the document. The
Trustee may, however, in its discretion 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 expense of the Company and shall incur no
liability of any kind by reason of such inquiry or investigation.

          (b) Before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate or an Opinion of Counsel or both. The Trustee shall
     not be liable for any action it takes or omits to take in good faith in
     reliance on the Officers' Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents, attorneys or custodians and
     shall not be responsible for the misconduct or negligence of any agent,
     attorney or custodian appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits
     to take in good faith that it believes to be authorized or within its
     rights or powers unless the Trustee's conduct constitutes bad faith,
     willful misconduct or negligence.

          (e) The Trustee may consult with counsel of its own selection, and the
     advice or Opinion of Counsel with respect to legal matters relating to this
     Indenture and the Securities shall be full and complete authorization and
     protection from liability in respect to any action taken, omitted or
     suffered by it hereunder in good faith and in accordance with the advice or
     opinion of such counsel.

          (f) The permissive rights of the Trustee to do things enumerated in
     this Indenture shall not be construed as a duty unless so specified herein.

          (g) The Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee security or indemnity satisfactory to the
     Trustee against the costs, expenses and liabilities which might be incurred
     by it in compliance with such request or direction.

          (h) The rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, the Trustee in each of its
     capacities hereunder.

          (i) 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.

          (j) In no event shall the Trustee be responsible or liable for
     special, indirect, or consequential loss or damage of any kind whatsoever
     (including, but not limited to,

                                       39

     loss of profit) irrespective of whether the Trustee has been advised of the
     likelihood of such loss or damage and regardless of the form of action.

     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.

     Section 7.04 Trustee's Disclaimer. The Trustee shall not be responsible for
and makes no representation as to the validity, priority or adequacy of this
Indenture or the Securities, it shall not be accountable for the Company's use
of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication.

     Section 7.05 Notice of Defaults. If a Default or Event of Default occurs
and is continuing and if it is known to a Trust Officer of the Trustee, the
Trustee shall mail to each Holder notice of the Default or Event of Default
within 90 days after it occurs. Except in the case of a Default described in
Section 6.01(i) or 6.01(ii), the Trustee may withhold the notice if and so long
as a committee of its Trust Officers in good faith determines that withholding
the notice is in the interests of Holders. 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
Trust Officer of the Trustee has received written notice of such Default.

     Section 7.06 Reports by Trustee to Holders. As promptly as practicable
after each December 31 beginning with December 31, 2007, and in any event prior
to March 31 in each year thereafter, the Trustee shall mail to each Holder a
brief report dated as of December 31 each year that complies with TIA Section
313(a), if and to the extent required by such subsection. The Trustee shall also
comply with TIA Section 313(b).

     The Company agrees to notify promptly the Trustee if and when the
Securities become listed on any stock exchange and of any delisting thereof.

     Section 7.07 Compensation and Indemnity. The Company shall pay to the
Trustee from time to time such compensation as shall be agreed upon from time to
time in writing for its services. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee upon request for all reasonable out-of-pocket
expenses incurred or made by it, including costs of collection, in addition to
the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts. The Company shall fully indemnify the Trustee
against any and all loss, liability, claim, damage or expense (including
reasonable attorneys' fees and expenses) incurred by it in connection with the
acceptance and administration of this trust and the performance of its duties
hereunder, including the costs and expenses of defending itself against any
claim (whether asserted by the Company, any Holder or any other Person). The
Trustee

                                       40

shall notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company of any claim for which it may
seek indemnity of which a Trust Officer has actually received written notice
shall not relieve the Company of its obligations hereunder except to the extent
such failure shall have materially prejudiced the Company. The Company shall
defend the claim and the Trustee shall cooperate in the defense. If the Trustee
is advised by counsel in writing that it may have available to it defenses which
are in conflict with the defenses available to the Company, then the Trustee may
have separate counsel and the Company shall pay the reasonable fees and expenses
of such counsel. The Company need not reimburse any expense or indemnify against
any loss, liability, claim, damage or expense incurred by the Trustee through
the Trustee's own bad faith, willful misconduct or negligence. The Company need
not pay for any settlement made by the Trustee without the Company's consent.
All indemnifications and releases from liability granted hereunder to the
Trustee shall extend to its officers, directors, employees, agents, attorneys,
custodians, successors and assigns.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest (including Liquidated Damages and Additional Amounts,
if any) on particular Securities.

     The Company's obligations pursuant to this Section shall survive the
resignation or removal of the Trustee and the discharge of this Indenture. When
the Trustee incurs expenses after the occurrence of a Default specified in
Section 6.01(viii) or 6.01(ix) with respect to the Company, the expenses are
intended to constitute expenses of administration under the Bankruptcy Law.

     Section 7.08 Replacement of Trustee. The Trustee may resign at any time by
so notifying the Company at least 30 days prior to the proposed resignation. The
Holders of a majority in aggregate principal amount of the Securities then
outstanding may remove the Trustee by so notifying the Trustee. The Company
shall remove the Trustee if:

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

          (b) the Trustee is adjudged bankrupt or insolvent;

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

          (d) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns, is removed by the Company or by the Holders of a
majority in aggregate principal amount of the Securities then outstanding, or if
a vacancy exists in the office of Trustee for any reason (the Trustee in such
event being referred to herein as the retiring Trustee), the Company shall
promptly appoint a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to 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

                                       41

Holders. The retiring Trustee shall upon payment of all of its costs and the
costs of its agents and counsel promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section
7.07.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% or more in aggregate principal amount of the Securities then outstanding may
petition at the expense of the Company any court of competent jurisdiction for
the appointment of a successor Trustee.

     If the Trustee fails to comply with Section 7.10, any Holder who has been a
bona fide Holder of a Security for at least six months may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

     Notwithstanding the replacement of the Trustee pursuant to this Section,
the Company's obligations under Section 7.07 shall continue for the benefit of
the retiring 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 or banking association, the
resulting, surviving or transferee corporation or banking association without
any further act shall be the successor Trustee.

     In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trust created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
such successor to the Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Securities or in this Indenture provided that the
certificate of the Trustee shall have.

     Section 7.10 Eligibility; Disqualification. The Trustee shall at all times
satisfy the requirements of TIA Section 310(a). The Trustee shall have (or, in
the case of a corporation included in a bank holding company system, the related
bank holding company shall have) a combined capital and surplus of at least
$50,000,000 as set forth in its (or its related bank holding company's) most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b), subject to the penultimate paragraph thereof; provided, however,
that there shall be excluded from the operation of TIA Section 310(b)(1) any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

     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.

                                       42

     Section 7.12 Trustee's Application for Instructions from the Company. Any
application by the Trustee for written instructions from the Company may, at the
option of the Trustee, set forth in writing any action proposed to be taken or
omitted by the Trustee under this Indenture and the date on and/or after which
such action shall be taken or such omission shall be effective. The Trustee
shall not be liable to the Company for any action taken by, or omission of, the
Trustee in accordance with a proposal included in such application on or after
the date specified in such application (which date shall not be less than three
Business Days after the date any Officer of the Company actually receives such
application, unless any such Officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of any omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                                    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 pursuant to Section 2.07) for cancellation or (b) all outstanding
Securities have become due and payable or have been converted, and the Company
irrevocably deposits with the Trustee cash sufficient to pay all amounts due and
owing on all outstanding Securities (other than Securities replaced pursuant to
Section 2.07) or delivers all amounts owing on conversion, as the case may be,
and if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 2.07, cease to be of
further effect; provided, however, that the foregoing shall not discharge the
Company's obligation to effect conversion, registration of transfer or exchange
of Securities in accordance with the terms of this Indenture. The Trustee shall
acknowledge satisfaction and discharge of this Indenture with respect to the
Securities on demand of the Company accompanied by an Officers' Certificate and
an 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 promptly turn over to the Company upon request any excess money or
securities held by them at any time.

     Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal or interest that remains unclaimed for two years, and,
thereafter, Holders entitled to the money must look to the Company for payment
as general creditors.

                                    ARTICLE 9

                                   AMENDMENTS

     Section 9.01 Without Consent of Holders. The Company and the Trustee may
amend or supplement this Indenture or the Securities without the consent of any
Holder to:

                                       43

          (a) to add guarantees with respect to the Securities or secure the
     Securities or remove any such guarantees;

          (b) to evidence the assumption of the Company's obligations by a
     successor Person under Article 5;

          (c) to surrender any of the Company's rights or powers under this
     Indenture;

          (d) to add covenants or Events of Default for the benefit of the
     Holders of Securities;

          (e) eliminate the right to elect to satisfy the Company's conversion
     obligation entirely in shares of Common Stock;

          (f) cure any omission or correct any inconsistency in this Indenture,
     so long as such action will not materially adversely affect the interests
     of Holders;

          (g) to cure any ambiguity, manifest error or defect;

          (h) to modify or amend this Indenture to permit the qualification of
     this Indenture or any supplemental indenture under the Trust Indenture Act
     of 1939 as then in effect;

          (i) to establish the forms or terms of the Securities;

          (j) to evidence the acceptance of appointment by a successor Trustee;

          (k) to provide for uncertificated Securities in addition to or in
     place of Certificated Securities; provided, however, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;

          (l) to conform, as necessary, this Indenture and the form or terms of
     the Securities to the "Description of Notes" as set forth in the offering
     memorandum dated August 24, 2007 relating to the initial placement of the
     Securities; or

          (m) to make any other change to this Indenture or forms or terms of
     the Securities so long as such change will not adversely affect the
     interests of the Holders of the Securities.

     After an amendment under this Section 9.01 becomes effective, the Company
shall mail to Holders a notice briefly describing such amendment. The failure to
give such notice to all such Holders, or any defect therein, shall not impair or
affect the validity of an amendment under this Section.

     Section 9.02 With Consent of Holders. With the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time outstanding
(voting as a single class), the Company and the Trustee may amend or modify this
Indenture or the Securities. However,

                                       44

without the consent of each Holder affected, an amendment to, or modification
of, this Indenture or the Securities may not:

          (a) reduce the principal amount of or change the Stated Maturity of
     any Security;

          (b) reduce the rate or extend the time for payment of interest
     (including Liquidated Damages and Additional Amounts, if any) on any
     Security;

          (c) make any change that adversely affects the right to require the
     Company to repurchase a Security, reduce any amount payable upon repurchase
     of any Security (including upon the occurrence of a Fundamental Change) or
     change the time at which or circumstances under which the Securities may or
     shall be repurchased;

          (d) adversely change the terms upon which the Securities may be
     redeemed;

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

          (f) change the currency in which any Security is payable;

          (g) impair the right of a Holder to convert any Security in accordance
     with its terms or reduce the number of shares of Common Stock or amount of
     any other property receivable upon conversion;

          (h) reduce the quorum or voting requirements under this Indenture;

          (i) change the Company's obligation to maintain an office or agency in

          (j) amend or modify any provision of this Indenture relating to
     amendment or modification or waiver of provisions of this Indenture that
     themselves may not be amended without the consent of each Holder affected;
     or

          (k) reduce the percentage of Securities required for consent to any
     amendment or modification of this Indenture.

     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 shall comply with the TIA.

                                       45

     Section 9.04 Revocation and Effect of Consents, Waivers and Actions. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Holder. An amendment
or waiver becomes effective upon the execution of such amendment or waiver by
the Trustee.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to give their consent or take any
other action described above or required or permitted to be taken pursuant to
this Indenture. If a record date is fixed, then notwithstanding the immediately
preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such
action, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 120 days after
such record date.

     Section 9.05 Notation on or Exchange of Securities. Securities
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a
notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Securities so
modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for
outstanding Securities.

     Section 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 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
be provided with, and (subject to the provisions of Section 7.01) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture.

     Section 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

                                   CONVERSIONS

     Section 10.01 Conversion Rights. (a) A Holder of Securities may convert
such Securities, in whole or in part, prior to the close of business on the
Business Day immediately

                                       46

preceding the Stated Maturity; provided, however, that Holders may convert their
Securities only in the circumstances and to the extent specified in clauses (i)
through (vi) below:

          (i) during any fiscal quarter after the fiscal quarter ending
     September 30, 2007, if the Closing Sale Price per share of the Common Stock
     for at least 20 Trading Days during the 30-consecutive-Trading Day-period
     ending on the last Trading Day of the preceding fiscal quarter exceeds 130%
     of the Conversion Price per share of Common Stock on such last Trading Day;

          (ii) during the 5 Business Days immediately following any
     five-consecutive- Trading-Day period in which the Trading Price per $1,000
     principal amount of the Securities (as determined following a request by a
     Holder of the Securities in accordance with the procedures described in
     Section 10.01(c)) for each day of such period was less than 98% of the
     product of (x) the Closing Sale Price and (y) the Conversion Rate of the
     Securities on each such Trading Day;

          (iii) after the Company or the Trustee has issued a notice of
     redemption of the Securities pursuant to Section 3.01 hereof, at any time
     prior to the close of business one Business Day prior to the Redemption
     Date for such Securities, even if such Securities are not otherwise
     convertible at such time;

          (iv) at any time after the Company gives notice to Holders of
     Securities of any election by it to distribute to all, or substantially
     all, Holders of Common Stock:

          (A) rights or warrants entitling such Holders of the Common Stock to
     purchase, for a period expiring within 60 days after the date for such
     distribution, shares of Common Stock at less than the Closing Sale Price of
     the Common Stock on the Trading Day immediately preceding the announcement
     date of the distribution, or

          (B) assets (including cash), debt securities (or other evidences of
     indebtedness) or rights or warrants to purchase the Company's securities,
     which distribution has a value per share of Common Stock as determined by
     the Board of Directors exceeding 10% of the Closing Sale Price of the
     Common Stock on the Trading Day immediately preceding the announcement date
     of the distribution,

in each case, until the earlier of the close of business on the Business Day
immediately prior to the Ex-Dividend Date or the Company's announcement that
such distribution will not take place, provided that no Holder may exercise this
right to convert if such Holder may participate in the distribution without
conversion;

          (v) if a Fundamental Change occurs, regardless of whether a Holder has
     the right to require the Company to repurchase the Securities as described
     in Section 3.08, at any time from or including the effective date of the
     transaction until and including the 30th Business Day following such
     effective date; and

          (vi) at any time on or after April 1, 2027 until the close of business
     on the Business Day immediately preceding the Stated Maturity.

                                       47

          (b) The Company will determine on a daily basis whether the Securities
     are convertible as a result of the Closing Sale Price of the Common Stock
     pursuant to Section 10.01(a)(i) and will notify the Trustee if the
     Securities are so convertible.

          (c) The Trustee shall have no obligation to determine the Trading
     Price of the Securities as described in Section 10.01(a)(ii) unless the
     Company has requested such determination; and the Company shall have no
     obligation to make such request unless a Holder provides the Company with
     reasonable evidence that the Trading Price per $1,000 principal amount of
     Securities would be less than 98% of the product of (x) the Closing Sale
     Price of the Common Stock and (y) the Conversion Rate of the Securities on
     such day. At such time, the Company will instruct the Trustee to determine
     the Trading Price of the Securities beginning on the next Trading Day and
     on each successive Trading Day until the Trading Price per $1,000 principal
     amount of Securities is greater than or equal to 98% of the product of the
     Closing Sale Price of the Common Stock and the Conversion Rate of the
     Securities. The Trustee's sole duty in respect of such determination shall
     consist of requesting and receiving, and, if applicable, averaging the
     quotations provided by the independent nationally recognized securities
     dealers referred to in the definition of "Trading Price." The Trustee shall
     be entitled at its sole discretion to consult with the Company and to
     request the assistance of the Company in connection with the Trustee's
     duties and obligations pursuant to this Section 10.01(c) and the Company
     agrees, if requested by the Trustee, to cooperate with, and provide
     assistance to, the Trustee in carrying out its duties under this Section
     10.01(c).

          (d) If the Company makes a distribution described in Section
     10.01(a)(iv), the Company shall notify Holders at least 20 Business Days
     prior to the Ex-Dividend Date for such distribution.

          (e) The Company will notify Holders of the Securities and the Trustee
     on the same date on which the Company publicly announces any Fundamental
     Change, but in no event less than 5 Business Days prior to the anticipated
     effective date of such Fundamental Change.

          (f) The Company appoints the Trustee as the initial Conversion Agent.
     The Trustee may resign from its appointment as Conversion Agent at any time
     and the Company shall then appoint a new Conversion Agent.

          (g) Securities with respect to which a Repurchase Notice or a
     Fundamental Change Repurchase Notice has been given by the Holder may be
     converted pursuant to this Section 10.01 only if the Repurchase Notice or
     Fundamental Change Repurchase Notice has been withdrawn in accordance with
     the provisions of Section 3.09.

          (h) Whenever any event described in clauses (i) through (vi) of
     Section 10.01(a) shall occur such that the Securities become convertible as
     provided in this Section 10.01, the Company shall promptly inform the
     Trustee, issue a press release and use its reasonable efforts to post such
     information on its website or otherwise publicly disclose the information,
     or provide notice to the Holders of the Securities in a manner contemplated
     by this Indenture, including through the facilities of DTC, which press

                                       48

     release, website posting, notice or other public disclosure, as the case
     may be, shall include:

               (i) a description of such event;

               (ii) a description of the periods during which the Securities
          shall be convertible as provided in clauses (i) through (vi) of
          Section 10.01(a);

               (iii) a statement of whether an adjustment to the Conversion Rate
          shall take effect in respect of such event pursuant to Section 10.06
          through 10.11 below; and

               (iv) the procedures Holders of the Securities must follow to
          convert their Securities in accordance with Section 10.03 below,
          including the name and address of the Conversion Agent.

          (i) Notwithstanding any other provision of the Securities or this
     Indenture, no Holders of Securities shall be entitled to receive shares of
     Common Stock upon conversion of the Securities to the extent that receipt
     of such shares of Common Stock would cause any holder of beneficial
     interests (together with such holder's Affiliates) to exceed the Ownership
     Limit (as such term is defined in the Company's Articles of Amendment and
     Restatement in effect as of the date hereof). Any attempted conversion of
     Securities in excess of the Ownership Limit, in the absence of a waiver
     from the Company, shall be void ab initio to the extent of such excess, and
     the related Securities or portions thereof shall be returned by the Company
     to the Holder as promptly as practicable. The Company shall have no further
     obligation to the Holder with respect to such voided exchange and such
     Securities will be treated as if they had not been submitted for exchange.
     A Holder of returned Securities may resubmit such Securities for exchange
     at a later date subject to compliance with the terms hereof and the
     ownership limitations described in this Section 10.01(i).

     Section 10.02 Conversion Consideration.

          (a) Subject to the qualifications and the satisfaction of the
     conditions and during the periods described in Section 10.01(a), Holders
     shall be entitled to convert their Securities in denominations of $1,000
     principal amount or integral multiples thereof initially at a conversion
     rate of 92.7085 shares per $1,000 principal amount of Securities, which
     will be subject to adjustments as described in Sections 10.06 through
     10.11, but will not be adjusted for accrued interest (the "CONVERSION
     RATE"). The "CONVERSION PRICE" at any given time is equal to the principal
     amount of a Security divided by the Conversion Rate.

          (b) On the third Business Day following the expiration of the Cash
     Settlement Averaging Period, the Company shall deliver to the Holder,
     through the Conversion Agent, an amount (the "SETTLEMENT AMOUNT") equal to
     the sum of the Daily Settlement Amounts for each of the 20 consecutive
     Trading Days in the Cash Settlement Averaging Period, subject to the
     provisions of Section 10.02(d).

                                       49

          The "DAILY SETTLEMENT AMOUNT," for each of the 20 consecutive Trading
     Days in the Cash Settlement Averaging Period, shall consist of:

          (i) cash in an amount equal to the lesser of (x) $50 (the "DAILY
     MEASUREMENT VALUE") and (y) the Daily Conversion Value; and

          (ii) if the Daily Conversion Value exceeds the Daily Measurement
     Value, a number of shares of Common Stock equal to (x) the difference
     between the Daily Conversion Value and the Daily Measurement Value divided
     by (y) the Closing Sale Price of the Common Stock for such Trading Day as
     adjusted pursuant to Section 10.20.

          The "DAILY CONVERSION VALUE" means, for each of the 20 consecutive
     Trading Days during the Cash Settlement Averaging Period, one-twentieth
     (1/20th) of the product of (x) the Conversion Rate and (y) the Daily VWAP
     on such Trading Day.

          The "CASH SETTLEMENT AVERAGING PERIOD" with respect to any Securities
     means the 20-consecutive-Trading-Day period beginning (x) on the Redemption
     Date, if prior to the relevant Conversion Date the Company has called the
     Securities that are being converted for redemption, (y) on the 27th Trading
     Day immediately preceding the Stated Maturity, if the relevant Conversion
     Date is on or after the 30th day immediately preceding the Stated Maturity,
     and (z) in all other instances, on the second Trading Day after the
     relevant Conversion Date.

          The "DAILY VWAP" for the Common Stock means, for each of the 20
     consecutive Trading Days during the Cash Settlement Averaging Period, the
     per share volume-weighted average price on the New York Stock Exchange as
     displayed under the heading "Bloomberg VWAP" on Bloomberg page "AHR
     *equity** VAP" (or its equivalent successor if such page is not
     available) in respect of the period from scheduled open of trading until
     the scheduled close of trading of the primary trading session on such
     Trading Day (or if such volume-weighted average price is unavailable, the
     market value of one share of the Common Stock on such Trading Day
     determined by a nationally recognized independent investment banking firm
     retained for this purpose by the Company, using a volume-weighted method).
     The Daily VWAP will be determined without regard to after hours trading or
     any other trading outside of the regular trading session hours.

          (c) Any payments of cash and, if Common Stock is to be delivered, a
     stock certificate or certificates for the related number of shares of
     Common Stock, will be delivered to the Holders, or a book-entry transfer
     therefor through DTC will be made.

          (d) Notwithstanding the other provisions of this Article 10, any time
     on or prior to September 1, 2012 the Company may irrevocably elect, in its
     sole discretion without the consent of the Holders of the Securities, to
     deliver, upon conversion of Securities, in lieu of the Settlement Amount
     specified in Section 10.02(b), solely shares of Common Stock (and cash in
     lieu of fractional shares) in accordance with the provisions of this
     Section 10.02(d) (a "PHYSICAL SETTLEMENT ELECTION"). If the Company makes a
     Physical Settlement Election, the Company will deliver to Holders, in
     respect of

                                       50

     any Securities they convert, a number of shares of Common Stock equal to
     (i) the aggregate principal amount of Securities to be converted (ii)
     divided by $1,000 and (iii) multiplied by the Conversion Rate (which will
     include any increase to reflect any Additional Shares which Holders may be
     entitled to receive as described under Section 10.20). The Company will
     deliver such shares on the third Business Day after the Conversion Date.
     Prior to making any Physical Settlement Election, the Company may
     irrevocably elect to waive its right to make any such election, effective
     upon the Company's delivery to the Trustee of a notice that it is
     irrevocably waiving its ability to make a Physical Settlement Election at
     any time with respect to the Securities. If the Company makes a Physical
     Settlement Election, that election will be irrevocable and its right to
     waive the ability to make a Physical Settlement Election will expire.

          (e) The Company shall pay, in lieu of any fractional shares of Common
     Stock that would be otherwise issuable upon conversion of any Securities, a
     cash amount equal to the number of such fractional shares multiplied by the
     Daily VWAP on the Trading Day immediately preceding the Conversion Date.

     Section 10.03 Conversion Procedures. (a) To convert a Security, a Holder
shall (i) complete and manually sign a Conversion Notice or a facsimile of the
Conversion Notice, a form of which is on the back of the Security or may be
obtained from the Conversion Agent, and deliver such Conversion Notice to the
Conversion Agent, which notice shall be irrevocable, (ii) surrender the Security
to the Conversion Agent, (iii) if required by the Conversion Agent, furnish
appropriate endorsement and transfer documents, (iv) pay all transfer or similar
taxes required to be paid by such Holder pursuant to Section 10.04 and (v) if
required pursuant to Section 11.01(d), pay funds equal to interest payable on
the next Interest Payment Date. If a Person's interest is a beneficial interest
in a Global Security, to convert, such Person shall comply with requirements
(iii), (iv) and (v) above and comply with the Depositary's procedures for
converting a beneficial interest into a Global Security. The date a Holder
complies with all of the applicable requirements is the "CONVERSION DATE."

          (b) Securities will be deemed to have been converted immediately prior
     to the close of business on the Conversion Date and the converting Holder
     will be treated as a shareholder of record of the Company as of such time.

          (c) No payment or adjustment will be made for dividends on, or other
     distributions with respect to, any Common Stock except as provided in
     Sections 10.06 to 10.09 below. Upon conversion of a Security, a Holder will
     not receive any cash payment of interest (including Liquidated Damages and
     Additional Amounts, if any) unless such conversion occurs between a Record
     Date and the Interest Payment Date to which that Record Date relates.

          (d) If the last day on which a Security may be converted is not a
     Business Day, the Security may be surrendered on the next succeeding day
     that is a Business Day.

          (e) Provisions of this Indenture that apply to conversion of all of a
     Security also apply to conversion of a portion of a Security. Upon
     surrender of a Security that is converted in part, the Company shall
     execute, and the Trustee shall authenticate and

                                       51

     deliver to the Holder, a new Security or Securities in an authorized
     denomination equal in principal amount to the unconverted portion of the
     Security surrendered.

     Section 10.04 Taxes on Conversions. If a Holder converts a Security, the
Company shall pay any documentary, stamp or similar issue or transfer tax due on
the issue of any 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 or delivered in a name other than the Holder's name. 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 Common
Stock is to be delivered in a name other than the Holder's name. Nothing herein
shall preclude any tax withholding required by law or regulations.

     Section 10.05 Company to Provide Stock. The Company shall, prior to
issuance of any Securities under this Article 10, and from time to time as may
be necessary, reserve out of its authorized but unissued shares of Common Stock
a sufficient number of shares of Common Stock to permit the conversion of the
Securities.

     Any 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 or
similar rights and shall be free of any lien or adverse claim. The Company will
endeavor promptly to comply with all federal and state securities laws
regulating the offer and delivery of Common Stock, if any, 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 shares of Common Stock are then listed or quoted.

     Section 10.06 Adjustment for Change in Capital Stock. If, after the Issue
Date of the Securities, the Company:

          (a) pays a dividend or makes another distribution payable exclusively
     in shares of Common Stock on the Company's Common Stock;

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

          (c) combines the outstanding shares of Common Stock into a smaller
     number of shares;

then the Conversion Rate in effect immediately prior to such action shall be
adjusted based on the following formula:

                              CR(1) = CR(0) x OS(1)
                                              -----
                                              OS(0)

                                       52

where

     CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
     Date for such dividend or distribution, or the effective date of such share
     split or share combination;

     CR(1) = the new Conversion Rate in effect immediately after the Ex-Dividend
     Date for such dividend or distribution, or the effective date of such share
     split or share combination;

     OS(0) = the number of shares of Common Stock outstanding immediately prior
     to such Ex-Dividend Date, or effective date; and

     OS(1) = the number of shares of Common Stock outstanding immediately prior
     to such Ex- Dividend Date, or effective date but after giving effect to
     such dividend, distribution, share split or share combination.

     If any dividend or distribution described in this Section 10.06 is declared
but not so paid or made, the new Conversion Rate shall be readjusted to the
Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

     Section 10.07 Adjustment for Rights Issue. If, after the Issue Date of the
Securities, the Company distributes to all, or substantially all, holders of the
Company's Common Stock any rights, warrants or options entitling them, for a
period of not more than 60 days after the date of issuance thereof, to subscribe
for or to purchase shares of Common Stock at an exercise price per share of
Common Stock less than the average of the Closing Sale Prices of the Common
Stock for each Trading Day in the 10-consecutive-Trading-Day period ending on
the Trading Day immediately preceding the time of announcement of such issuance,
the Conversion Rate shall be adjusted in accordance with the following formula:

                           CR(1) = CR(0) x (OS(0) + X)
                                           -----------
                                           (OS(0) + Y)

where

     CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
     Date for such distribution;

     CR(1) = the new Conversion Rate in effect immediately after the Ex-Dividend
     Date for such distribution;

     OS(0) = the number of shares of Common Stock outstanding immediately prior
     to the Ex-Dividend Date for such distribution;

     X = the number of shares of Common Stock issuable pursuant to such rights,
     warrants or options; and

     Y = the number of shares of Common Stock equal to the quotient of (A) the
     aggregate price payable to exercise such rights, warrants or options and
     (B) the average of the

                                       53

     Closing Sale Prices of the Common Stock for each Trading Day in the
     10-consecutive-Trading Day period ending on the Trading Day immediately
     preceding the date of announcement for the issuance of such rights,
     warrants or options.

     For purposes of this Section 10.07, in determining whether any rights,
warrants or options entitle the Holders to subscribe for or purchase the
Company's Common Stock at less than the average of the Closing Sale Prices for
each Trading Day in the applicable 10-consecutive-Trading Day period, there
shall be taken into account any consideration the Company receives for such
rights, warrants or options and any amount payable on exercise thereof, with the
value of such consideration, if other than cash, to be determined by the
Company's Board of Directors.

     If any right, warrant or option described in this Section 10.07 is not
exercised prior to the expiration of the exercisability thereof, the new
Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect if such right, warrant or option had not been so issued.

     Section 10.08 Adjustment for Other Distributions. If, after the Issue Date
of the Securities, the Company distributes to all, or substantially all, holders
of its Common Stock evidence of indebtedness or other assets or property,
excluding:

          (A) dividends, distributions, rights, warrants or options referred to
     in Section 10.06 or 10.07 above;

          (B) dividends or distributions paid exclusively in cash; and

          (C) Spin-Offs described below in this Section 10.08,

then the Conversion Rate will be adjusted based on the following formula:

                           CR(1) = CR(0) x     SP(0)
                                           -------------
                                           (SP(0) - FMV)

where

     CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
     Date for such distribution;

     CR(1) = the new Conversion Rate in effect immediately after the Ex-Dividend
     Date for such distribution;

     SP(0) = the average of the Closing Sale Prices of the Common Stock for each
     Trading Day in the 10-consecutive Trading-Day period ending on the Trading
     Day immediately preceding the Ex-Dividend Date for such distribution; and

     FMV = the fair market value (as determined in good faith by the Board of
     Directors) of the shares of Capital Stock, evidences of indebtedness,
     assets or property distributed with respect to each outstanding share of
     Common Stock on the earlier of the Record Date or the Ex-Dividend Date for
     such distribution.

                                       54

     With respect to an adjustment pursuant to this Section 10.08, where there
has been a payment of a dividend or other distribution to all, or substantially
all, holders of Common Stock of shares of Capital Stock of any class or series,
or similar equity interest, of or relating to any Subsidiary or other business
unit (a "SPIN-OFF"), the Conversion Rate in effect immediately before the close
of business on the effective date of the Spin-Off will be adjusted based on the
following formula:

                         CR(1) = CR(0) x (FMV(0)+MP(0))
                                         --------------
                                             MP(0)

where

     CR(0) = the Conversion Rate in effect immediately prior to the effective
     date of the Spin-Off;

     CR(1) = the new Conversion Rate after the Spin-Off;

     FMV(0) = the average of the Closing Sale Prices of the Capital Stock or
     similar equity interest distributed to holders of Common Stock applicable
     to one share of Common Stock over the first 10 consecutive Trading Days
     after, and including, the effective date of the Spin-Off; and

     MP(0) = the average of the Closing Sale Prices of the Common Stock over the
     10 consecutive Trading Days after, and including, the effective date of the
     Spin-Off.

     An adjustment to the Conversion Rate made pursuant to the immediately
preceding paragraph will occur on the 10th Trading Day from and including the
effective date of the Spin-Off; provided that in respect of any conversion
within the 10 Trading Days following, and including, the effective date of any
Spin-Off, references within this Section 10.08 to 10 Trading Days shall be
deemed replaced with such lesser number of Trading Days as have elapsed between
the effective date of such Spin-Off and the Conversion Date in determining the
Conversion Rate.

     If any such dividend or distribution described in this Section 10.08 is
declared but not paid or made, the new Conversion Rate shall be readjusted to be
the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.

     Section 10.09 Adjustment for Cash Dividends. If, after the Issue Date of
the Securities, the Company makes any cash dividend or distribution to all, or
substantially all, Holders of its outstanding Common Stock, other than regular
quarterly cash dividends (without regard to the actual period in which paid)
that do not exceed the Reference Dividend, the Conversion Rate will be adjusted
based on the following formula:

                           CR(1) = CR(0) x     SP(0)
                                           -----------
                                           (SP(0) - C)

                                       55

where

     CR(0) = the Conversion Rate in effect immediately prior to the Ex-Dividend
     Date for such distribution;

     CR(1) = the new Conversion Rate in effect immediately after the Ex-Dividend
     Date for such distribution;

     SP(0) = the average of the Closing Sale Prices of the Common Stock for each
     Trading Day in the 10-consecutive-Trading-Day period ending on the Trading
     Day immediately preceding the Ex-Dividend Date for such distribution; and

     C = the amount in cash per share that the Company distributes to holders of
     its Common Stock in respect of the applicable quarterly period that exceeds
     the Reference Dividend.

     If any dividend or distribution described in this Section 10.09 is declared
but not so paid or made, the new Conversion Rate shall be readjusted to the
Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

     The Reference Dividend amount is subject to adjustment in a manner
inversely proportional to adjustments to the Conversion Rate; provided that no
adjustment will be made to the Reference Dividend amount for any adjustment made
to the Conversion Rate under this Section 10.09.

     Notwithstanding the foregoing, if an adjustment is required to be made
under this Section 10.09 as a result of a distribution that is not a regular
quarterly dividend, the Reference Dividend amount will be deemed to be zero.

     Section 10.10 Adjustment for Company Tender Offer. If, after the Issue Date
of the Securities, the Company or any of its subsidiaries makes a payment in
respect of a tender offer or exchange offer for its Common Stock, to the extent
that the cash and value of any other consideration included in the payment per
share of its Common Stock exceeds the Closing Sale Price of a share of its
Common Stock on the Trading Day following the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Conversion
Rate will be adjusted based on the following formula:

                     CR(1) = CR(0) x (AC + (SP(1) x OS(1)))
                                     ----------------------
                                           (SP(1) x OS(0))

where

     CR(0) = the Conversion Rate in effect on the day immediately following the
     date such tender or exchange offer expires;

     CR(1) = the new Conversion Rate in effect after such tender or exchange
     offer expires;

                                       56

     AC = the aggregate value of all cash and any other consideration (as
     determined by the Company's Board of Directors) paid or payable for the
     Company's Common Stock purchased in such tender or exchange offer;

     OS(0) = the number of shares of the Company's Common Stock outstanding
     immediately prior to the date such tender or exchange offer expires;

     OS(1) = the number of shares of the Company's Common Stock outstanding
     immediately after the date such tender or exchange offer expires (after
     giving effect to the purchase or exchange of shares pursuant to such tender
     or exchange offer); and

     SP(1) = the average of the Closing Sale Prices of the Company's Common
     Stock for each Trading Day in the 10-consecutive-Trading-Day period
     commencing on the Trading Day following the date such tender or exchange
     offer expires.

     The adjustment to the Conversion Rate under this Section 10.10 will occur
on the 10th Trading Day from, and including, the Trading Day following the date
such tender or exchange offer expires; provided that in respect of any
conversion within 10 Trading Days immediately following, and including, the
expiration date of any tender or exchange offer, references with respect to 10
Trading Days shall be deemed replaced with such lesser number of Trading Days as
have elapsed between the expiration date of such tender or exchange offer and
the Conversion Date in determining the Conversion Rate.

     Section 10.11 Additional Adjustments. (a) The Company may, in its sole
discretion, increase the Conversion Rate as its Board of Directors deems
advisable to avoid or diminish any income tax to Holders of its Securities
resulting from any dividend or distribution of Capital Stock issuable upon
conversion of the Securities (or rights to acquire Capital Stock) or from any
event treated as such for income tax purposes.

          (b) The Company may, from time to time, to the extent permitted by
     applicable law, increase the Conversion Rate by any amount for any period
     of at least 20 Business Days if its Board of Directors has determined that
     such increase would be in the Company's best interests. If its Board of
     Directors makes such determination, it will be conclusive. The Company will
     give Holders of Securities at least 15 days' prior notice of such an
     increase in the Conversion Rate.

          (c) To the extent that the Company has a rights plan in effect upon
     any conversion of the Securities into Common Stock, a Holder will receive,
     in addition to the Common Stock, the rights under the rights plan, unless,
     prior to any conversion, the rights have separated from the Common Stock,
     in which case the Conversion Rate will be adjusted at the time of
     separation as described in Section 10.08. A further adjustment will occur
     as described in Section 10.08 above, if such rights become exercisable to
     purchase different securities, evidences of indebtedness or assets, subject
     to readjustment in the event of the expiration, termination or redemption
     of such rights.

          (d) Following:

          (A) any reclassification of the Company's Common Stock;

                                       57

          (B) a consolidation, merger, binding share exchange or combination
     involving the Company; or

          (C) a conveyance, transfer, sale, lease or other disposition to
     another Person or entity of all or substantially all of the Company's
     assets;

     the Settlement Amount in respect of the Company's conversion obligation
     will be computed as set forth in Section 10.02 above, based on the kind and
     amount of shares of stock, securities, other property or assets (including
     cash or any combination thereof) that Holders of the Company's Common Stock
     are entitled to receive in respect of each share of the Company's Common
     Stock in such transaction (the "REFERENCE PROPERTY") and Reference Property
     will be delivered in lieu of the shares of the Company's Common Stock that
     would have otherwise been deliverable upon conversion. If Holders of Common
     Stock would be entitled to elect the kind of consideration for their Common
     Stock received in any transaction described in the previous sentence, the
     Company shall make adequate provision (which shall be similar to the
     provisions of the election to be made holders of the Common Stock) whereby
     the Holders shall have the opportunity, on a timely basis, to determine the
     form of consideration into which all of the Notes, treated as a single
     class, shall be convertible. Such determination shall be based on the
     weighted average of elections made by Holders of the Notes who participate
     in such determination and shall be subject to any limitations to which all
     of the holders of the Common Stock are subject, such as pro rata reductions
     applicable to any portion of the consideration payable. If no Holders
     participate in such election than the kind of consideration for their
     Common Stock shall be based on the weighted average of the kind and amount
     of consideration received by the holders of the Company's Common Stock that
     affirmatively make such an election. The determination of the Reference
     Property will apply to all of the Securities and the Company will notify
     the Trustee of the composition of the Reference Property promptly after it
     is determined.

     All calculations under this Article 10 shall be made to the nearest
1/10,000th of a share, as the case may be.

     The Company will not take any action that would result in an adjustment
pursuant to this Section 10 without complying with the shareholder approval
rules of The New York Stock Exchange or any stock exchange on which the Common
Stock is listed at the relevant time.

     Section 10.12 When No Adjustment Required. No adjustment shall be made:

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

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

                                       58

          (c) upon the issuance of any shares of Common Stock pursuant to any
     option, warrant, right or exercisable, exchangeable or convertible security
     and outstanding as of the date the Securities were first issued (unless
     explicitly otherwise provided in this Article 10);

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

          (e) for accrued and unpaid interest (including Liquidated Damages and
     Additional Amounts, if any).

     Section 10.13 De minimis Impact on Conversion Rate. Notwithstanding
anything in the foregoing provisions of this Article 10, to the contrary, the
Company will not be required to adjust the Conversion Rate unless the adjustment
would result in a change of at least 1% of the Conversion Rate. However, the
Company will carry forward any adjustments that are less than 1% of the
Conversion Rate and make such carried forward adjustments, regardless of whether
the aggregate adjustment is less than 1%, upon any conversion of the Securities.

     Section 10.14 Notice of Adjustment. Whenever the Conversion Rate is
adjusted, the Company shall promptly mail to Holders a notice of the adjustment.
The Company shall file with the Trustee and the Conversion Agent such notice
briefly stating the facts requiring the adjustment and the manner of computing
it. The notice of adjustment 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 notice of adjustment except to exhibit
the same to any Holder desiring inspection thereof.

     Section 10.15 Company Determination Final. Any determination that the
Company or the Board of Directors must make pursuant to Section 10.02(d), 10.06,
10.07, 10.08, 10.09, 10.10, 10.11, 10.12 or 10.15 is conclusive, absent manifest
error.

     Section 10.16 Trustee's Adjustment Disclaimer. The Trustee has no duty to
determine when the Securities are convertible or when an adjustment under this
Article 10 should be made, how it should be made or what it should be. 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 10. Each Conversion Agent shall have the same
protection under this Section 10.16 as the Trustee.

     Section 10.17 Simultaneous Adjustments. In the event that this Article 10
requires adjustments to the Conversion Rate under more than one of Sections
10.06, 10.07, 10.08 or 10.09, only one such adjustment shall made by applying,
first, the provisions of Section 10.06, second, the provisions of Section 10.08,
third, the provisions of Section 10.09 and, fourth, the provisions of Section
10.07.

     Section 10.18 Successive Adjustments. After an adjustment to the Conversion
Rate under this Article 10, any subsequent event requiring an adjustment under
this Article 10 shall cause an adjustment to the Conversion Rate as so adjusted.

                                       59

     Section 10.19 Limitation on Adjustments. The Company shall not take any
action that would result in an adjustment pursuant to the foregoing provisions
in this Article 10 if that adjustment would reduce the Conversion Price below
the then par value of the shares of Common Stock issuable upon conversion of the
Securities.

     Section 10.20 Adjustment to Conversion Rate Upon Certain Fundamental Change
Transactions. If, after the Issue Date of the Securities, the Fundamental Change
Effective Date of a Fundamental Change pursuant to paragraphs (i) or (iii) of
the definition of Fundamental Change set forth in Section 3.08, occurs prior to
September 1, 2012 and 10% or more of the consideration for the Company's Common
Stock in the transaction consists of consideration other than common stock that
is traded or scheduled to be traded immediately following such transaction on a
U.S. national or regional securities exchange (collectively, "LISTED COMMON
EQUITY") and the Securities are surrendered for conversion in connection with
such transaction, the Company will increase the Conversion Rate by a number of
additional shares of the Company's Common Stock (the "ADDITIONAL SHARES")
determined pursuant to this Section 10.20.

     A conversion of the Securities will be deemed for these purposes to be "IN
CONNECTION WITH" a Fundamental Change transaction if the related Conversion
Notice is received by the Conversion Agent during the period from and including
the Fundamental Change Effective Date until and including the 30th Business Day
following such Fundamental Change Effective Date.

     The Company shall mail to Holders not later than five Business Days prior
to the anticipated effective date of the Fundamental Change a notice describing
the Fundamental Change and the Holders' right to Additional Shares.

     The number of Additional Shares shall be determined by reference to the
table below with reference to the date such Fundamental Change transaction
becomes effective (the "FUNDAMENTAL CHANGE EFFECTIVE DATE") and the price (the
"SHARE PRICE") paid per share of Common Stock in such Fundamental Change
transaction. If the Holders of Common Stock receive only cash in the Fundamental
Change transaction, the Share Price shall be the cash amount paid per share of
Common Stock. Otherwise, the Share Price shall be the average of the Closing
Sale Prices of the Common Stock on the five Trading Days immediately prior to
but not including the Fundamental Change Effective Date.

     As of any date upon which the Conversion Rate is adjusted, the Share Prices
set forth in the first row of the table below shall be adjusted such that the
adjusted Share Prices shall equal the Share Prices applicable immediately prior
to such adjustment multiplied by a fraction, the numerator of which is the
Conversion Rate immediately prior to such adjustment and the denominator of
which is the Conversion Rate as so adjusted pursuant to Sections 10.06 through
10.11. If the Share Price is between two Share Prices in the table or the
Fundamental Change Effective Date is between two Effective Dates in the table,
the number of Additional Shares will be determined by straight-line
interpolation between the number of Additional Shares set forth for the higher
and lower Share Prices and the two Effective Dates, as applicable, based on a
365-day year. If the Share Price is in excess of $40.00 per share (subject to
adjustment as set forth herein), or if the Share Price is less than $9.18 per
share (subject to adjustment as set forth herein), no Additional Shares will be
added to the Conversion Rate.

     Notwithstanding the foregoing, in no event will the number of Additional
Shares of Common Stock by which the Conversion Rate is adjusted pursuant to this
Section 10.20 exceed 16.2239 shares per $1,000 principal amount of Securities,

                                   ARTICLE 11

                               PAYMENT OF INTEREST

     Section 11.01 Payment of Interest. (a) The Company shall pay interest on
the Securities at a rate of 11.75% per annum, payable semi-annually in arrears
on September 1 and March 1 of each year (each, an "INTEREST PAYMENT DATE"),
commencing on March 1, 2008. For so long as the Securities are held in
book-entry only form, interest (including Liquidated Damages and Additional
Amounts, if any) on a Security shall be paid to the Holder of such Security at
the close of business on the Business Day before the Interest Payment Date
(each, a "RECORD DATE"). In the event that the Securities do not remain in
book-entry only form or are not in the form of a Global Certificate, the Company
will have the right to select Record Dates, which will be at least one Business
Day before an Interest Payment Date. Interest shall be computed on the basis of
a 360-day year comprised of twelve 30-day months and will accrue from August 29,
2007 or from the most recent date to which interest has been paid or duly
provided for. In the event of the maturity, conversion, redemption or repurchase
of a Security by the Company at the option of the Holder, interest shall cease
to accrue on such Security.

          (b) If any Interest Payment Date, Stated Maturity, Redemption Date or
     Repurchase Date (including upon the occurrence of a Fundamental Change)
     falls on a day that is not a Business Day, then the required payment will
     be made on the next succeeding Business Day with the same force and effect
     as if made on the date that the payment was due, and no additional interest
     will accrue on that payment for the period from and after the Interest
     Payment Date, Stated Maturity, Redemption Date or Repurchase Date, as the
     case may be, to such next succeeding Business Day.

                                       61

          (c) Upon conversion of a Security, (i) a Holder shall not receive any
     cash payment of interest (unless such conversion occurs between a Record
     Date and the Interest Payment Date to which it relates) and (ii) except as
     set forth in clause (d) below, the Company's delivery to a Holder of the
     full amount of cash and shares, if any, of Common Stock into which the
     Security is convertible together with any cash payment of factional shares
     shall be deemed to satisfy its obligation with respect to the principal
     amount of such Security, and any accrued but unpaid interest (including
     Liquidated Damages and Additional Amounts, if any). As a result, accrued
     but unpaid interest (including Liquidated Damages and Additional Amounts,
     if any) up to but excluding the Conversion Date will be deemed to be paid
     in full rather than cancelled, extinguished or forfeited.

          (d) If Securities are surrendered for conversion by a Holder after the
     close of business on any Record Date but prior to the opening of business
     on the Interest Payment Date to which such Record Date relates, Holders of
     such Securities at the close of business on the Record Date will receive an
     amount equal to the interest (including Liquidated Damages and Additional
     Amounts, if any) payable on the Securities on the corresponding Interest
     Payment Date notwithstanding the conversion. Such Securities, upon
     surrender for conversion, must be accompanied by funds equal to the amount
     of interest (including Liquidated Damages and Additional Amounts, if any)
     payable on the Securities so converted on the corresponding Interest
     Payment Date. However, no such payment shall be made:

          (i)   in connection with any conversion following the regular Record
                Date immediately preceding the Stated Maturity;

          (ii)  if the Company has specified a Redemption Date that is after a
                Record Date and on or prior to the corresponding Interest
                Payment Date;

          (iii) if the Company has specified a Fundamental Change Repurchase
                Date that is after a Record Date and on or prior to the
                corresponding Interest Payment Date;

          (iv)  if a scheduled Repurchase Date occurs after a Record Date and on
                or prior to the corresponding Interest Payment Date; or

          (v)   to the extent of any overdue interest (including overdue
                Liquidated Damages and Additional Amounts, if any) if overdue
                interest, Liquidated Damages or Additional Amounts exist at the
                time of conversion with respect to such Security.

     In addition, notwithstanding the forgoing, the Company shall pay, on the
Stated Maturity, accrued and unpaid interest to but excluding the Stated
Maturity on any Securities surrendered for conversion on or after August 1, 2027
to the converting Holder.

     Section 11.02 Additional Amounts. Notwithstanding the provisions
described in Section 6.02, the sole remedy under this Indenture and any Security
for an Event of Default relating to the failure to comply with the Company's
reporting obligations to the Trustee and the SEC, as set

                                       62

forth in this Indenture, and for any failure to comply with the requirements of
Section 314(a)(1) of the Trust Indenture Act, shall, for the 180 days after the
occurrence of such an Event of Default, consist exclusively of the right to
receive additional interest on the Securities at an annual rate equal to 0.25%
of the aggregate principal amount of the Securities (the "ADDITIONAL AMOUNTS").
Any such Additional Amounts shall be payable in the same manner and on the same
dates as the stated interest payable on the Securities. The Additional Amounts
shall accrue on all outstanding Securities from and including the date on which
such an Event of Default first occurs to, but not including, the 181st day
thereafter (or, if applicable, the earlier date on which such Event of Default
is cured or waived). If such Event of Default is continuing on the 181st day
after such Event of Default first occurs, the Securities shall be subject to
acceleration as provided in Section 6.02. The provisions of this Section 11.02
shall not affect the rights of Holders of Securities in the event of the
occurrence of any other Events of Default.

     Section 11.03 Defaulted Interest. Any installment of interest that is
payable, but is not punctually paid or duly provided for on any Interest Payment
Date ("DEFAULTED INTEREST") shall forthwith cease to be payable to the Holders
in whose names the Securities were registered on the Record Date applicable to
such installment of interest. The Company shall make payment of any Defaulted
Interest (including any interest on such Defaulted Interest) to the Holders in
whose names the Securities are registered at the close of business on a special
record date for the payment of such Defaulted Interest (a "SPECIAL RECORD
DATE"), which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Holders entitled to such Defaulted Interest as provided in this
Section 11.03. Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest, which shall be not more than 15 calendar
days and not less than ten calendar days prior to the date of the proposed
payment and not less than ten calendar 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 sent, first-class mail, postage
prepaid, to each Holder at such Holder's address as it appears in the
registration books of the Registrar, not less than ten calendar days prior to
such Special Record Date. 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 Holders in whose names the
Securities are registered at the close of business on such Special Record Date.

     Section 11.04 Interest Rights Preserved. Subject to the foregoing
provisions of this Article 11 and Section 2.06, each Security delivered under
this Indenture upon registration of transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES

          or otherwise make available for use by Holders a previously filed
          effective Shelf Registration Statement, not later than 210 days after
          the date hereof (the "EFFECTIVENESS TARGET DATE", and the date of such

          Registration Statement becomes effective until the date that the Notes
          and the shares of Common Stock issuable upon exchange thereof have
          ceased to be Transfer Restricted Securities.

          (b) Not less than 30 days prior to the Effectiveness Target Date, the
     Company shall mail the Notice and Questionnaire to the Holders. Each Holder
     that becomes a Notice Holder (and provides such additional information as

     the initial Registration Statement made available to Holders under the
     Shelf Registration Statement.

          (c) If the Shelf Registration Statement ceases to be effective for any
     reason at any time during the Effectiveness Period (other than because all
     Transfer Restricted Securities registered thereunder shall have been resold
     pursuant thereto or shall have otherwise ceased to be Transfer Restricted
     Securities), the Company shall use commercially reasonable efforts to
     obtain the prompt withdrawal of any order suspending the effectiveness
     thereof or file or designate a subsequent Shelf Registration Statement
     covering all of the securities that as of the date of such filing or
     designation are Transfer Restricted Securities. If such a subsequent Shelf
     Registration Statement is filed or designated (and is not already
     effective), the Company shall use commercially reasonable efforts to cause
     the subsequent Shelf Registration Statement to become effective as promptly
     as is practicable after such filing or designation and to keep such
     subsequent Shelf Registration Statement continuously effective until the
     end of the Effectiveness Period.

          (d) The Company shall use commercially reasonable efforts to
     supplement and amend the Shelf Registration Statement if required by the
     rules, regulations or instructions applicable to the registration form used
     by the Company for such Shelf Registration Statement, if required by the
     Securities Act or as reasonably requested by the Initial Purchasers or by
     the Trustee on behalf of the Holders of the Transfer Restricted Securities
     covered by such Shelf Registration Statement.

          (e) The Company shall cause the Shelf Registration Statement and the
     related Prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement or such amendment or
     supplement, and any Issuer Free Writing Prospectus, as of the date thereof,
     (i) to comply in all material respects with the applicable requirements of
     the Securities Act, and (ii) not to contain any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary in order to make the statements therein (in the case
     of the Prospectus and any Issuer Free Writing Prospectus, in light of the
     circumstances under which they were made) not misleading.

          (f) Each Holder agrees that if such Holder wishes to sell Transfer
     Restricted Securities pursuant to a Shelf Registration Statement and
     related Prospectus, it will do so only in accordance with the terms and
     conditions of this Agreement. Each Holder wishing to sell Transfer
     Restricted Securities pursuant to a Shelf Registration Statement and
     related Prospectus from and after the Effectiveness Date agrees to deliver

                                        6

     a Notice and Questionnaire to the Company at least 10 Business Days prior
     to any intended distribution of Transfer Restricted Securities under the
     Shelf Registration Statement. From and after the Effectiveness Date, the
     Company shall, as promptly as practicable after the date a Notice and
     Questionnaire is delivered to it, and in any event upon the later of (x) 10
     Business Days after such date or (y) 10 Business Days after the expiration
     of any Suspension Period in effect when the Notice and Questionnaire is
     delivered or put into effect within 10 Business Days of such delivery date:

               (i) if required by applicable law, file with the SEC a
          post-effective amendment to the Shelf Registration Statement or
          prepare and, if required by applicable law, file a supplement to the
          related Prospectus or a supplement or amendment to any document
          incorporated therein by reference or file any other required document
          so that the Holder delivering such Notice and Questionnaire is named
          as a selling securityholder in the Shelf Registration Statement and
          the related Prospectus in such a manner as to permit such Holder to
          deliver such Prospectus to purchasers of the Transfer Restricted
          Securities in accordance with applicable law and, if the Company shall
          file a post-effective amendment to the Shelf Registration Statement,
          use commercially reasonable efforts to cause such post-effective
          amendment to become effective under the Securities Act as promptly as
          is practicable, but in any event by the date (the "AMENDMENT
          EFFECTIVENESS DEADLINE DATE") that is 45 days after the date such
          post-effective amendment is required by this clause to be filed;

               (ii) provide such Holder a copy of each document filed pursuant
          to Section 2(f)(i); and

               (iii) notify such Holder as promptly as practicable after the
          effectiveness under the Securities Act of any post-effective amendment
          filed pursuant to Section 2(f)(i);

provided that if such Notice and Questionnaire is delivered during a Suspension
Period, the Company shall so inform the Holder delivering such Notice and
Questionnaire and shall take the actions set forth in clauses (i), (ii) and
(iii) above upon expiration of the Suspension Period in accordance with Section
4(b); provided, however, that if a post-effective amendment to the Shelf
Registration Statement is required, the Company will not be obligated to file
more than one such amendment for all such Holders during any fiscal quarter
unless the principal amount of the Transfer Restricted Securities to be included
in such amendment is more than $5 million. Notwithstanding the preceding
sentence, the Company will not be obligated to file more than two such
supplements to the related Prospectus during any fiscal quarter. Notwithstanding
anything contained herein to the contrary, (i) the Company shall be under no
obligation to name any Holder that is

                                        7

not a Notice Holder as a selling securityholder in any Registration Statement or
related Prospectus and (ii) the Amendment Effectiveness Deadline Date shall be
extended by up to 10 Business Days from the Expiration of a Suspension Period
(and the Company shall incur no obligation to pay Liquidated Damages during such
extension) if such Suspension Period shall be in effect on the Amendment
Effectiveness Deadline Date.

     3. Liquidated Damages.

          (a) If:

               (i) the Shelf Registration Statement is not filed, or on file,

               (v) except as provided in Section 4(b)(ii) hereof, the Shelf
          Registration Statement is filed and has become effective but, during
          the Effectiveness Period, shall thereafter cease to be effective or

          consecutive Business Days; or

               (vi) Suspension Periods (as defined below) exceed an aggregate of
          90 days in any 360-day period;

     ("LIQUIDATED DAMAGES") with respect to the Transfer Restricted Securities
     from and including the day following the Registration Default to but
     excluding the earlier of (1) the day on which the Registration Default has
     been cured and (2) the date the Shelf Registration Statement is no longer
     required to be kept effective, accruing at a rate:

                    (A) in respect of the Notes, to each holder of Notes, (x)
               with respect to the first 90-day period during which a
               Registration Default shall have occurred and be continuing,

                                        8

               equal to 0.25% per annum of the aggregate principal amount of the

               day following the day the Registration Default shall have
               occurred and be continuing, equal to 0.50% per annum of the
               aggregate principal amount of the Notes; provided that in no
               event shall Liquidated Damages accrue at a rate per year
               exceeding 0.50% of the aggregate principal amount of the Notes;
               and

                    (B) in respect of the Notes that are Transfer Restricted
               Securities submitted for conversion into Common Stock during the

               Stock, the holder will not be entitled to receive any Liquidated
               Damages with respect to such Common Stock but (x) will be
               entitled to a conversion rate adjustment in accordance with the
               terms of the Notes as set forth in the Indenture and (y) will
               receive from the Company on the settlement date with respect to
               such conversion, accrued and unpaid Liquidated Damages calculated

               defined in the Indenture); and

                    (C) in respect of Common Stock issued upon conversion of
               Notes, each holder of such Common Stock will not be entitled to
               any Liquidated Damages if the Registration Default with respect
               to such Common Stock occurs after the holder has converted the
               Notes into Common Stock.

          (b) All accrued Liquidated Damages shall be paid in arrears to Record
     Holders by the Company on each Liquidated Damages Payment Date. Upon the
     cure of all Registration Defaults relating to any particular Transfer
     Restricted Security, the accrual of applicable Liquidated Damages will
     cease.

     All obligations of the Company set forth in this Section 3 that are
outstanding with respect to any Transfer Restricted Security at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such Transfer Restricted Security

          (a) In connection with the Shelf Registration Statement, the Company
     shall comply with all the provisions of Section 4(b) hereof and shall use
     commercially reasonable efforts to effect such registration to

                                        9

     permit the sale of the Transfer Restricted Securities, and pursuant
     thereto, shall as expeditiously as possible prepare and file with the
     Commission a Shelf Registration Statement relating to the registration on
     any appropriate form under the Securities Act, or otherwise make available
     for use by Holders a previously filed Shelf Registration Statement.

          (b) In connection with the Shelf Registration Statement and any
     Prospectus required by this Agreement to permit the sale or resale of
     Transfer Restricted Securities, the Company shall:

               (i) Subject to any notice by the Company in accordance with this
          Section 4(b) of the existence of any fact or event of the kind
          described in Section 4(b)(iv)(D), use commercially reasonable efforts
          to keep the Shelf Registration Statement continuously effective during
          the Effectiveness Period; upon the occurrence of any event that would
          cause the Shelf Registration Statement or the Prospectus contained
          therein (A) to contain a material misstatement or omission or (B) not
          to be effective and usable for resale of Transfer Restricted
          Securities during the Effectiveness Period, the Company shall file
          promptly a post-effective amendment to the Shelf Registration
          Statement or an amendment or supplement to the related Prospectus or
          file any other required document, in the case of clause (A),
          correcting any such misstatement or omission, and, in the case of
          either clause (A) or (B), use commercially reasonable efforts to cause
          any such amendment to become effective and the Shelf Registration
          Statement and the related Prospectus to become usable for their
          intended purposes as soon as practicable thereafter;

               (ii) Notwithstanding Section 4(b)(i) hereof, the Company may
          suspend the effectiveness of the Shelf Registration Statement (each
          such period, a "SUSPENSION PERIOD"):

                    (x) if an event occurs and is continuing as a result of
          which the Shelf Registration Statement, the Prospectus, any amendment
          or supplement thereto, or any document incorporated by reference
          therein would, in the Company's judgment, contain an untrue statement
          of a material fact or omit to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading; and

                    (y) if the Company determines in good faith that the
          disclosure of a material event at such time may be detrimental to the
          Company and its subsidiaries.

                                       10

          Upon the occurrence of any event described in clauses (x) and (y) of
          this Section 4(b)(ii), the Company shall give notice to the Holders
          that the availability of the Shelf Registration is suspended and, upon
          actual receipt of any such notice, each Holder agrees not to sell any
          Transfer Restricted Securities pursuant to the Shelf Registration
          until such Holder's receipt of copies of the supplemented or amended
          Prospectus provided for in Section 4(b) hereof. The Suspension Period
          shall not exceed an aggregate of 90 days in any 360-day period. The
          Company shall not be required to specify in the written notice to the
          Holders the nature of the event giving rise to the Suspension Period.

                    (iii) Prepare and file with the Commission such amendments
               and post-effective amendments to the Shelf Registration Statement
               as may be necessary to keep the Shelf Registration Statement
               effective during the Effectiveness Period; cause the Prospectus
               to be supplemented by any required Prospectus supplement, and as
               so supplemented to be filed pursuant to Rule 424 under the
               Securities Act, and to comply fully with the applicable
               provisions of Rule 424 under the Securities Act in a timely
               manner; and comply with the provisions of the Securities Act with
               respect to the disposition of all Transfer Restricted Securities
               covered by the Shelf Registration Statement during the applicable
               period in accordance with the intended method or methods of
               distribution by the sellers thereof set forth or to be set forth
               in the Shelf Registration Statement or supplement to the
               Prospectus;

                    (iv) Advise the selling Holders and any Initial Purchaser
               that has provided in writing to the Company a telephone or
               facsimile number and address for notices, promptly and, if
               requested by such selling Holders, to confirm such advice in
               writing (which notice pursuant to clauses (B) through (E) below
               shall be accompanied by an instruction to suspend the use of the
               Prospectus until the Company shall have remedied the basis for
               such suspension):

                         (A) when the Prospectus, any Prospectus supplement, any
                    post-effective amendment or any Issuer Free Writing
                    Prospectus has been filed, and, with respect to the Shelf
                    Registration Statement or any post-effective amendment
                    thereto, when the same has become effective,

                         (B) of any request by the Commission for amendments or
                    supplements to the Shelf Registration Statement, the
                    Prospectus or any Issuer Free Writing Prospectus or for
                    additional information relating thereto,

                                       11

                         (C) of the issuance by the Commission of any stop order
                    suspending the effectiveness of the Shelf Registration
                    Statement under the Securities Act or of any notice that
                    would prevent its use, or of the suspension by any state
                    securities commission of the qualification of the Transfer
                    Restricted Securities for offering or sale in any
                    jurisdiction, or the threatening or initiation of any

                    any event, during the Effectiveness Period, that makes any
                    statement of a material fact made in the Shelf Registration

                    thereto, or any document incorporated by reference therein
                    untrue, or that requires the making of any additions to or
                    changes in the Shelf Registration Statement or the
                    Prospectus in order to make the statements therein (in the
                    case of the Prospectus, in the light of the circumstances
                    under which they were made) not misleading, or

                    information that may conflict with the information contained
                    in the Registration Statement.

                    (v) If at any time the Commission shall issue any stop order
               suspending the effectiveness of the Shelf Registration Statement

               to obtain the withdrawal or lifting of such order at the earliest
               possible time, including, if necessary, by filing an amendment to

               and will provide to each Holder who is named in the Shelf
               Registration Statement prompt notice of the withdrawal of any
               such order or of the filing or effectiveness of any such
               amendment or new registration statement;

                    (vi) Make available at reasonable times for inspection by

               post-effective amendment to the Shelf Registration Statement such
               information as the Managing Underwriters reasonably agree should
               be included therein and to which the Company does not reasonably
               object and shall make all required filings of such Prospectus
               supplement or post-effective amendment as soon as

                                       16

          practicable after it is notified of the matters to be included or
          incorporated in such Prospectus supplement or post-effective
          amendment.

               (xxv) Use commercially reasonable efforts to take all other steps
          necessary to effect the registration of the Transfer Restricted
          Securities covered by the Shelf Registration Statement.

               (xxvi) Enter into customary agreements (including, if requested,
          an underwriting agreement in customary form) and take all other
          appropriate actions in order to expedite or facilitate the
          registration or the disposition of the Transfer Restricted Securities,
          and in connection therewith, if an underwriting agreement is entered
          into, cause the same to contain indemnification provisions and
          procedures no less favorable than those set forth in Section 6 hereof.

     The actions set forth in clauses (xx), (xxi), (xxii) and (xxiii) of this
Section 4(b) shall be performed at (A) the effectiveness of the Shelf
Registration Statement and each post-effective amendment thereto; and (b) each
closing under any underwriting or similar agreement as and to the extent
required thereunder.

          (c) Each Holder agrees by acquisition of a Transfer Restricted
     Security that, upon receipt of any notice (a "SUSPENSION NOTICE") from the
     Company of the existence of any fact of the kind described in Section
     4(b)(iv)(B) through (E) hereof, such Holder will forthwith discontinue
     disposition of Transfer Restricted Securities pursuant to the Shelf
     Registration Statement and use of the Prospectus and any related Free
     Writing Prospectuses until:

               (i) such Holder has received copies of the supplemented or
          amended Prospectus or applicable Issuer Free Writing Prospectus
          contemplated by Section 4(b)(xi) hereof; or

               (ii) such Holder is advised in writing by the Company that the
          use of the Prospectus and any applicable Issuer Free Writing
          Prospectus may be resumed, and has received copies of any additional
          or supplemental filings that are incorporated by reference in the
          Prospectus.

If so directed by the Company, each Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities and any Issuer Free Writing Prospectus that was current at the time
of receipt of such Suspension Notice.

                                       17

          (d) Each Holder agrees by acquisition of a Transfer Restricted
     Security, that no Holder shall be entitled to sell any of such Transfer
     Restricted Securities pursuant to a Registration Statement, or to receive a
     Prospectus relating thereto, unless such Holder has furnished the Company
     with a fully completed Notice and Questionnaire as required pursuant to
     Section 2(b) or Section 2(f) hereof (including the information required to
     be included in such Notice and Questionnaire) and the information set forth
     in the next sentence. The Company may require each Notice Holder of Notes
     to be sold pursuant to the Shelf Registration Statement to furnish to the
     Company such information regarding the Holder and the distribution of such
     Notes as the Company may from time to time reasonably require for inclusion
     in such Registration Statement. Each Notice Holder agrees promptly to
     furnish to the Company all information required to be disclosed in order to
     make the information previously furnished to the Company by such Notice
     Holder not misleading and any other information regarding such Notice
     Holder and the distribution of such Transfer Restricted Securities as the
     Company may from time to time reasonably request in writing. Any sale of
     any Transfer Restricted Securities by any Holder shall constitute a
     representation and warranty by such Holder that the information relating to
     such Holder and its plan of distribution is as set forth in the Prospectus
     delivered by such Holder in connection with such disposition, that such
     Prospectus does not as of the time of such sale contain any untrue
     statement of a material fact relating to or provided by such Holder or its
     plan of distribution and that such Prospectus does not as of the time of
     such sale omit to state any material fact relating to or provided by such
     Holder or its plan of distribution necessary to make the statements in such
     Prospectus, in light of the circumstances under which they were made not
     misleading. The Company may exclude from such Shelf Registration Statement
     the Notes of any Holder that unreasonably fails to furnish such information
     within a reasonable time after receiving such request.

     5. Registration Expenses.

          All expenses incident to the Company's performance of or compliance
     with this Agreement shall be borne by the Company regardless of whether a
     Shelf Registration Statement becomes effective, including, without
     limitation:

          (a) all registration and filing fees and expenses (including filings
     made with the FINRA);

          (b) all fees and expenses of compliance with federal securities and
     state Blue Sky or securities laws, if required;

                                       18

          (c) all expenses of printing (including printing of Prospectuses,
     Issuer Free Writing Prospectuses and certificates for the Common Stock to
     be issued upon conversion of the Notes) and the Company's expenses
               for messenger and delivery services and telephone;

          (d) all reasonable and documented fees and disbursements of counsel to
     the Company;

          (e) all application and filing fees in connection with listing (or
     authorizing for quotation) the Common Stock on a national securities
     exchange or automated quotation system pursuant to the requirements hereof;
     and

          (f) all fees and disbursements of independent registered public
     accountants of the Company.

     The Company shall bear its internal expenses (including, without
limitation, all salaries and expenses of their officers and employees performing
legal, accounting or other duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company. The Company shall pay all expenses customarily borne by issuers in an
underwritten offering as set forth in Section 8(c) hereof.

     6. Indemnification And Contribution.

          (a) The Company agrees to indemnify and hold harmless each Holder of
     Transfer Restricted Securities (including each Initial Purchaser), its
     directors, officers, employees and agents, and each person, if any, who
     controls any Holder within the meaning of the Securities Act or the
     Exchange Act (each, an "INDEMNIFIED HOLDER"), against any loss, claim,
     damage, liability or expense, as incurred, or any action in respect thereof
     (including, but not limited to, any loss, claim, damage, liability or
     expense relating to resales of the Transfer Restricted Securities)
     (collectively, "LOSSES"), to which such Indemnified Holder may become
     subject, insofar as any such Loss arises out of or is based upon:

               (i) any untrue statement or alleged untrue statement of a
          material fact contained in (A) the Shelf Registration Statement as
          originally filed or in any amendment thereof, or (B) any blue sky
          application or other document or any amendment or supplement thereto
          prepared or executed by the Company (or based upon written information
          furnished by or on behalf of the Company expressly for use in such
          blue sky application or other document or amendment or supplement)
          filed in any jurisdiction specifically for the purpose of qualifying
          any or all of the Transfer Restricted Securities under the securities
          law of any state or other jurisdiction

                                       19

          (such application or document being hereinafter called a "BLUE SKY
          APPLICATION"), or, in each case, the omission or alleged omission to
          state therein any material fact required to be stated therein or
          necessary to make the statements therein not misleading; or

               (ii) any untrue statement or alleged untrue statement of a
          material fact contained in any Issuer Free Writing Prospectus, any
          preliminary prospectus or the Prospectus (or any amendment or
          supplement thereto), or the omission or alleged omission therefrom of
          a material fact, in each case, necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading,

     and to reimburse each Indemnified Holder for any and all reasonable
     expenses (including the fees and disbursements of counsel) as they are
     incurred by such Indemnified Holder in connection with investigating,
     defending, settling, compromising or paying any such Loss; provided,
     however, that the foregoing indemnity agreement shall not apply to any Loss
     to the extent, but only to the extent, arising out of or based upon any
     untrue statement or alleged untrue statement or omission or alleged
     omission made in reliance upon and in conformity with written information
     furnished to the Company by or on behalf of such Holder (or its related
     Indemnified Holder) expressly for use therein (including, without
     limitation, information within such Holder's Notice and Questionnaire). The
     indemnity agreement set forth in this Section 6(a) shall be in addition to
     any liabilities that the Company may otherwise have.

          The Company also agrees to indemnify as provided in this Section 6(a)
     or contribute as provided in Section 6(e) hereof to Losses of each
     underwriter, if any, of Transfer Restricted Securities registered under a
     Shelf Registration Statement, their directors, officers, employees or
     agents and each person who controls such underwriter on substantially the
     same basis as that of the indemnification of the Initial Purchasers and the
     selling Holders provided in this Section 6(a) and shall, if requested by
     any Holder, enter into an underwriting agreement reflecting such agreement,
     as provided in Section 4(b)(xxvi) hereof.

          (b) Each Holder agrees, severally and not jointly, to indemnify and
     hold harmless the Company, each of its directors, each of its officers who
     sign the Shelf Registration Statement and each person, if any, who controls
     the Company within the meaning of the Securities Act or the Exchange Act
     (i) to the same extent as the foregoing indemnity from the Company to each
     such Holder, but only with reference to written information relating to
     such Holder furnished to the Company by or on

                                       20

     behalf of such Holder specifically for inclusion in the documents referred
     to in the foregoing indemnity and (ii) against any Loss, joint or several,
     including, but not limited to, any Loss relating to resales of the Transfer
     Restricted Securities, to which such person may become subject, insofar as
     any such Loss arises out of, or is based upon any Free Writing Prospectus
     used by such Holder without the prior consent of the Issuer, and in
     connection with any underwritten offering, the underwriters, provided that
     the indemnification obligation in this clause (ii) shall be several, not
     joint and several, among the Holders who used such Free Writing Prospectus.
     This indemnity agreement set forth in this Section shall be in addition to
     any liabilities which any such Holder may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     6 of notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against an indemnifying party
     under this Section 6, notify the indemnifying party in writing of the
     commencement thereof, but the failure to notify the indemnifying party (i)
     will not relieve it from liability under paragraph (a) or (b) above unless
     and to the extent it did not otherwise learn of such action and such
     failure results in the forfeiture by the indemnifying party of substantial
     rights and defenses and (ii) will not, in any event, relieve the
     indemnifying party from any obligations to any indemnified party other than
     the indemnification obligation provided in paragraph (a) or (b) above. In
     case any such action is brought against any indemnified party and such
     indemnified party seeks or intends to seek indemnity from an indemnifying
     party, the indemnifying party will be entitled to participate in, and, to
     the extent that it shall elect, jointly with all other indemnifying parties
     similarly notified, by written notice delivered to the indemnified party
     promptly after receiving the aforesaid notice from such indemnified party,
     to assume the defense thereof with counsel satisfactory to such indemnified
     party; provided, however, if the defendants in any such action include both
     the indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that a conflict may arise between the
     positions of the indemnifying party and the indemnified party in conducting
     the defense of any such action or that there may be legal defenses
     available to it and/or other indemnified parties that are different from or
     additional to those available to the indemnifying party, the indemnified
     party or parties shall have the right to select separate counsel to assume
     such legal defenses and to otherwise participate in the defense of such
     action on behalf of such indemnified party or parties. Upon receipt of
     notice from the indemnifying party to such indemnified party of such
     indemnifying party's election so to assume the defense of such action and
     approval by the indemnified party of counsel, the indemnifying party will
     not be liable to such indemnified party under this Section 6 for any legal
     or other expenses subsequently incurred by such indemnified party in
     connection with the defense thereof unless (i) the

                                       21

     indemnified party shall have employed separate counsel in accordance with
     the proviso to the preceding sentence (it being understood, however, that
     the indemnifying party shall not be liable for the expenses of more than
     one separate counsel (other than local counsel), reasonably approved by the
     indemnifying party, representing the indemnified parties who are parties to
     such action) or (ii) the indemnifying party shall not have employed counsel
     satisfactory to the indemnified party to represent the indemnified party
     within a reasonable time after notice of commencement of the action, in
     each of which cases the fees and expenses of counsel shall be at the
     expense of the indemnifying party.

          (d) The indemnifying party under this Section 6 shall not be liable
     for any settlement of any proceeding effected without its written consent,
     which shall not be withheld unreasonably, but if settled with such consent
     or if there is a final judgment for the plaintiff, the indemnifying party
     agrees to indemnify the indemnified party against any Loss by reason of
     such settlement or judgment. Notwithstanding the foregoing sentence, if at
     any time an indemnified party shall have requested an indemnifying party to
     reimburse the indemnified party for fees and expenses of counsel as
     contemplated by Section 6(c) hereof, the indemnifying party agrees that it
     shall be liable for any settlement of any proceeding effected without its
     written consent if (i) such settlement is entered into more than 30 days
     after receipt by such indemnifying party of the aforesaid request and (ii)
     such indemnifying party shall not have reimbursed the indemnified party in
     accordance with such request prior to the date of such settlement. No
     indemnifying party shall, without the prior written consent of the
     indemnified party, effect any settlement, compromise or consent to the
     entry of judgment in any pending or threatened action, suit or proceeding
     in respect of which any indemnified party is or could have been a party and
     indemnity was or could have been sought hereunder by such indemnified
     party, unless such settlement, compromise or consent (x) includes an
     unconditional release of such indemnified party from all liability on
     claims that are the subject matter of such action, suit or proceeding and
     (y) does not include a statement as to or an admission of fault,
     culpability or a failure to act, by or on behalf of any indemnified party.

          (e) If the indemnification provided for in this Section 6 is for any
     reason unavailable to or otherwise insufficient to hold harmless an
     indemnified party in respect of any Loss referred to therein, then each
     indemnifying party shall contribute to the aggregate amount paid or payable
     by such indemnified party, as incurred, as a result of any Loss referred to
     therein:

               (i) in such proportion as is appropriate to reflect the relative
          benefits received by the Company, on the one hand, and

                                       22

          the Holders, on the other hand, from the offering and sale of the
          Transfer Restricted Securities, on the one hand, and a Holder with
          respect to the sale by such Holder of the Transfer Restricted
          Securities, on the other hand, or

               (ii) if the allocation provided by Section (6)(e)(i) above is not
          permitted by applicable law, in such proportion as is appropriate to
          reflect not only the relative benefits referred to in Section 6(e)(i)
          above but also the relative fault of the Company, on the one hand, and
          the Holders, on the other hand, in connection with the statements or
          omissions or alleged statements or omissions that resulted in such
          Loss, as well as any other relevant equitable considerations.

     The relative benefits received by the Company, on the one hand, and the
     Holders, on the other hand, in connection with such offering and such sale
     of the Transfer Restricted Securities pursuant to this Agreement shall be
     deemed to be in the same respective proportions as the total net proceeds
     from the offering of the Notes purchased under the Purchase Agreement
     (before deducting expenses) received by the Company and the total proceeds
     received by the Holders with respect to their sale of Transfer Restricted
     Securities. The relative fault of the Company, on the one hand, and the
     Holders, on the other hand, shall be determined by reference to, among
     other things, whether any such untrue or alleged untrue statement of a
     material fact or omission or alleged omission to state a material fact
     relates to information supplied by the Company, on the one hand, or the
     Holders, on the other hand, and the parties' relative intent, knowledge,
     access to information and opportunity to timely correct or prevent such
     statement or omission. The Company and the Holders agree that it would not
     be just and equitable if contribution pursuant to this Section 6(e) were
     determined by pro rata allocation (even if the Holders were treated as one
     entity for such purpose) or by any other method of allocation that does not
     take account of the equitable considerations referred to in this Section
     6(e).

          The amount paid or payable by a party as a result of the Loss referred
     to above shall be deemed to include, subject to the limitations set forth
     in Section 6(c), any legal or other fees or expenses reasonably incurred by
     such party in connection with investigating or defending any action or
     claim.

          Notwithstanding the provisions of this Section 6, in no event will (i)
     any Holder be required to undertake liability to any person under this
     Section 6 for any amounts in excess of the dollar amount of the proceeds to
     be received by such Holder from the sale of such Holder's Transfer
     Restricted Securities (after deducting any fees, discounts and commissions

                                       23

     applicable thereto) pursuant to any Shelf Registration Statement under
     which such Transfer Restricted Securities are to be registered under the
     Securities Act and (ii) any underwriter be required to undertake liability
     to any person hereunder for any amounts in excess of the discount or
     commission payable to such underwriter with respect to the Transfer
     Restricted Securities underwritten by it and distributed to the public. No
     Person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Securities Act) shall be entitled to contribution from
     any Person who was not guilty of such fraudulent misrepresentation. The
     Holders' obligations to contribute as provided in this Section 6(e) are
     several and not joint.

          (f) The provisions of this Section 6 shall remain in full force and
     effect, regardless of any investigation made by or on behalf of any Holder
     or the Company or any of the officers, directors, employees, agents or
     controlling persons referred to in Section 6 hereof, and will survive the
     sale by a Holder of Transfer Restricted Securities.

     7. Rule 144A and Rule 144. The Company agrees with each Holder, for so long
as any Transfer Restricted Securities remain outstanding and during any period
in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange
Act, to make available, upon request of any Holder, to such Holder of Transfer
Restricted Securities in connection with any sale thereof and any prospective
purchaser of such Transfer Restricted Securities designated by such Holder, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A, and
(ii) is subject to Section 13 or 15(d) of the Exchange Act, to make all filings
required thereby in a timely manner in order to permit resales of such Transfer
Restricted Securities pursuant to Rule 144.

     8. Underwritten Registrations.

          (a) Any Holder of Transfer Restricted Securities who desires to do so
     may sell Transfer Restricted Securities (in whole or in part) in an
     underwritten offering; provided that (i) the Electing Holders of at least
     33-1/3% in aggregate principal amount of the Transfer Restricted Securities
     then covered by the Shelf Registration Statement shall request such an
     offering and (ii) at least such aggregate principal amount of such Transfer
     Restricted Securities shall be included in such offering (which shall be no
     less than $15 million aggregate principal amount); and provided further
     that the Company shall not be obligated to participate in more than one
     underwritten offering during the Effectiveness Period. Upon receipt of such
     a request, the Company shall provide all Holders of Transfer Restricted
     Securities written notice of the request, which notice shall inform such
     Holders that they have the opportunity to participate in the offering. If
     any of the Transfer Restricted Securities covered by the Shelf

                                       24

     Registration Statement are to be sold in an underwritten offering, the
     Managing Underwriters shall be selected by the Majority Holders.

          (b) No person may participate in any underwritten offering pursuant to
     the Shelf Registration Statement unless such person (i) agrees to sell such
     person's Transfer Restricted Securities on the basis reasonably provided in
     any underwriting arrangements approved by the persons entitled hereunder to
     approve such arrangements; (ii) completes and executes all questionnaires,
     powers of attorney, indemnities, underwriting agreements and other
     documents reasonably required under the terms of such underwriting
     arrangements; and (iii) if such Holder is not then a Notice Holder, such
     Holder returns a completed and signed Notice and Questionnaire to the
     Company in accordance with Section 2(b) or Section 2(f) hereof within a
     reasonable amount of time before such underwritten offering.

          (c) The Holders participating in any underwritten offering shall be
     responsible for any underwriting discounts and commissions and fees and,
     subject to Section 5 hereof, expenses of their own counsel. The Company
     shall pay all expenses customarily borne by issuers in an underwritten
     offering, including but not limited to filing fees, the fees and
     disbursements of its counsel and independent public accountants and any
     printing expenses incurred in connection with such underwritten offering.
     Notwithstanding the foregoing or the provisions of Section 4(b)(xxiv)
     hereof, upon receipt of a request from the Managing Underwriter or a
     representative of holders of a majority of the Transfer Restricted
     Securities to be included in an underwritten offering to prepare and file
     an amendment or supplement to the Shelf Registration Statement and
     Prospectus in connection with an underwritten offering, the Company may
     delay the filing of any such amendment or supplement for up to 90 days if
     the Board of Directors of the Company shall have determined in good faith
     that the Company has a bona fide business reason for such delay.

     9. Miscellaneous.

          (a) Free Writing Prospectuses. Each Holder represents that it has not
     prepared or had prepared on its behalf or used or referred to, and agrees
     that it will not prepare or have prepared on its behalf or use or refer to,
     any Free Writing Prospectus, and has not distributed and will not
     distribute any written materials in connection with the offer or sale of
     the Transfer Restricted Securities without the prior express written
     consent of the Company and, in connection with any underwritten offering,
     the underwriters. Any such Free Writing Prospectus consented to by the
     Company and, if applicable, the underwriters, as the case may be, is
     hereinafter referred to as a "PERMITTED FREE WRITING PROSPECTUS." The
     Company represents and agrees that it has treated and will treat, as the

                                       25

     case may be, each Permitted Free Writing Prospectus as an Issuer Free
     Writing Prospectus, including in respect of timely filing with the
     Commission, legending and recordkeeping.

          (b) Actions Affecting Transfer Restricted Securities. The Company
     shall not, directly or indirectly, take any action with respect to the
     Transfer Restricted Securities as a class that would adversely affect the
     ability of the Holders of Transfer Restricted Securities to include such
     Transfer Restricted Securities in a registration undertaken pursuant to
     this Agreement.

          (c) No Inconsistent Agreements. The Company has not, as of the date
     hereof, entered into, nor shall it, on or after the date hereof, enter
     into, any agreement with respect to its securities that is inconsistent
     with the rights granted to the Holders in this Agreement or otherwise
     conflicts with the provisions hereof. In addition, the Company shall not
     grant to any of its securityholders (other than the Holders of Transfer
     Restricted Securities in such capacity) the right to include any of its
     securities in the Shelf Registration Statement provided for in this
     Agreement other than the Transfer Restricted Securities.

          (d) Amendments and Waivers. This Agreement may not be amended,
     modified or supplemented, and waivers or consents to or departures from the
     provisions hereof may not be given, unless the Company has obtained the
     written consent of a Majority of Holders; provided, however, that with
     respect to any matter that directly or indirectly adversely affects the
     rights of any Initial Purchaser hereunder, the Company shall obtain the
     written consent of each such Initial Purchaser against which such
     amendment, qualification, supplement, waiver or consent is to be effective.
     Notwithstanding the foregoing (except the foregoing proviso), a waiver or
     consent to depart from the provisions hereof with respect to a matter that
     relates exclusively to the rights of Holders whose securities are being
     sold pursuant to a Shelf Registration Statement and does not directly or
     indirectly adversely affect the rights of other Holders, may be given by
     the Majority Holders, determined on the basis of Transfer Restricted
     Securities being sold rather than registered under such Shelf Registration
     Statement.

          (e) Notices. All notices and other communications provided for or
     permitted hereunder shall be made in writing by hand delivery, first class
     mail (registered or certified, return receipt requested), facsimile
     transmission, or air courier guaranteeing overnight delivery:

               (i) if to a Holder, at the address set forth on the records of
          the registrar under the Indenture or the transfer agent of the Common
          Stock, as the case may be; and

                                       26

               (ii) if to the Company, initially at its address set forth in the
          Purchase Agreement,

                    With a copy to:

                    Matthew J. Mallow, Esq.
                    Skadden, Arps, Slate, Meagher & Flom LLP
                    Four Times Square
                    New York, New York 10036

          All such notices and communications shall be deemed to have been duly
     given: at the time delivered by hand, if personally delivered; four
     Business Days after being deposited in the mail, postage prepaid, if
     mailed; when receipt acknowledged, if transmitted by facsimile; and on the
     next Business Day, if timely delivered to an air courier guaranteeing
     overnight delivery.

     Any party hereto may change the address for receipt of communications by
giving written notice to the others.

          (f) Successors and Assigns. This Agreement shall inure to the benefit
     of and be binding upon the successors and assigns of each of the parties,
     including without limitation and without the need for an express
     assignment, subsequent Holders of Transfer Restricted Securities. The
     Company hereby agrees to extend the benefit of this Agreement to any Holder
     and any such Holder may specifically enforce the provisions of this
     Agreement as if an original party hereto.

          (g) Counterparts. This Agreement may be executed in any number of
     counterparts and by the parties hereto in separate counterparts (including
     by facsimile), each of which when so executed shall be deemed to be an
     original and all of which taken together shall constitute one and the same
     agreement.

          (h) Notes Held by the Company or Their Affiliates. Whenever the
     consent or approval of Holders of a specified percentage of Transfer
     Restricted Securities is required hereunder, Transfer Restricted Securities
     held by the Company or its Affiliates (other than subsequent Holders if
     such subsequent Holders are deemed to be Affiliates solely by reason of
     their holding of such Transfer Restricted Securities) shall not be counted
     in determining whether such consent or approval was given by the Holders of
     such required percentage.

          (i) Headings. The headings in this Agreement are for convenience of
     reference only and shall not limit or otherwise affect the meaning hereof.

                                       27

          (j) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
     IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

          (k) Severability. If any one or more of the provisions contained
     herein, or the application thereof in any circumstance, is held invalid,
     illegal or unenforceable, the validity, legality and enforceability of any
     such provision in every other respect and of the remaining provisions
     contained herein shall not be affected or impaired thereby, it being
     intended that all of the rights and privileges of the parties shall be
     enforceable to the fullest extent permitted by law.

          (l) Entire Agreement. This Agreement is intended by the parties as a
     final expression of their agreement and intended to be a complete and
     exclusive statement of the agreement and understanding of the parties
     hereto in respect of the subject matter contained herein. There are no
     restrictions, promises, warranties or undertakings, other than those set
     forth or referred to herein with respect to the registration rights granted
     by the Company with respect to the Transfer Restricted Securities. This
     Agreement supersedes all prior agreements and understandings between the
     parties with respect to such subject matter.

                                       28

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.
