Purchase Payments or portion thereof made on or after the Endorsement Effective
Date as shown on the Endorsement Data Page that are included in the calculation
of the Benefit Base. If this Endorsement is added after the Contract Date, for
purposes of determining the Benefit Base, the Contract Value on the Endorsement

<PAGE>

MAXIMUM ANNUAL WITHDRAWAL PERCENTAGE ("MAWP")
The percentage used to determine the MAWA available for withdrawal each Benefit
Year under this Endorsement.

YOU, YOUR
The Covered Person(s) under this Endorsement.

                GUARANTEED MINIMUM WITHDRAWAL BENEFIT PROVISIONS

The Guaranteed Minimum Withdrawal Benefit described in this Endorsement provides
for guaranteed Withdrawals over the lifetime of the Covered Person(s), subject
to the following provisions:

GMWB CHARGE
The GMWB Charge percentage applicable to this Endorsement is as shown on the
Endorsement Data Page. If You surrender Your Contract and this Endorsement has
not been terminated, We will deduct a proportionate charge for the period of
time between the date of the last GMWB charge up to and including the date of
surrender.

CALCULATION OF THE COMPONENTS OF THE GMWB
The MAWA guaranteed under this Endorsement may change over time as a result of
increases or decreases in the Benefit Base as described below.

To determine the GMWB when the Bonus is not available, We use the following
components: Benefit Base Evaluation Period, Benefit Base, MAWP and MAWA. To
determine the GMWB when the Bonus is available, the following additional
components are used: Bonus Period, Bonus Base and Bonus Percentage. The
calculations for each component are detailed below.

BENEFIT BASE
If the GMWB is elected on the Contract Date, the initial Benefit Base is the
initial Eligible Purchase Payment. If the GMWB is elected after the Contract
Date, the initial Benefit Base is equal to the Contract Value on the Endorsement
Effective Date, which is subject to the Eligible Purchase Payment Limit shown on
the Endorsement Data Page. In each subsequent Benefit Year, the Benefit Base
equals the Benefit Base at the beginning of that Benefit Year plus any
subsequent Eligible Purchase Payments made during that Benefit Year, less
adjustments for Excess Withdrawals that occurred during that Benefit Year. The
Benefit Base is determined as detailed below and is not used in the calculation
of Contract Value or any other benefits under the Contract. On Benefit Year
anniversaries during the Benefit Base Evaluation Period, We determine if the
Benefit Base should be increased based on the maximum Anniversary Value or any
available Bonus. The calculation and components of this determination are
detailed below.

        CALCULATION OF THE BENEFIT BASE WHEN BONUS IS NOT AVAILABLE OR AFTER
        BONUS PERIOD The Benefit Base on each Benefit Year anniversary is based
        on the maximum Anniversary Value. Maximum Anniversary Value equals the
        highest Anniversary Value on any Benefit Year anniversary occurring
        during the Benefit Base Evaluation Period. On each Benefit Year
        anniversary occurring during the Benefit Base Evaluation Period, the
        Benefit Base is automatically increased to the Anniversary Value when
        the Anniversary Value is greater than both (a) and (b), where:

              (a) is the current Benefit Base; and

              (b) is all previous maximum Anniversary Values during the Benefit
                  Base Evaluation Period.

        CALCULATION OF THE BENEFIT BASE WHEN BONUS IS AVAILABLE
        The Bonus Base is used to calculate the amount of the Bonus during the
        Bonus Period. The Bonus amount is determined by multiplying the Bonus
        Percentage shown on the Endorsement Data Page by the Bonus Base. The
        initial Bonus Base is equal to the initial Eligible Purchase Payment.
        The Bonus Base is increased each time subsequent Eligible Purchase
        Payments are made. The Bonus Base also increases when the Benefit Base
        is increased as a result of a maximum Anniversary Value being achieved
        that is greater than both the current Benefit Base and all previous
        maximum Anniversary Values. The Bonus Base is decreased each time an
        Excess Withdrawal is taken, in the same proportion by which the Contract
        Value is reduced by the Excess Withdrawal. The Bonus Base is not used in
        the calculation of the Contract Value or any other benefits under the
        Contract.

        On each Benefit Year anniversary during the Bonus Period, We determine
        the amount to which the Bonus Base and / or the Benefit Base could
        increase. The components used to determine this amount are:

              (a) the Benefit Base calculated based on the maximum Anniversary
                  Value; and

                                       3

<PAGE>

              (b) the Bonus plus the current Benefit Base.

        If (a) is greater than (b), the Bonus Base and the Benefit Base are
        increased to the current Anniversary Value. If (b) is greater than (a),
        the Benefit Base is increased by the Bonus and the Bonus Base remains
        unchanged.

MAXIMUM ANNUAL WITHDRAWAL AMOUNT ("MAWA")
The MAWA is calculated by multiplying the Benefit Base by the Maximum Annual
Withdrawal Percentage ("MAWP"). The applicable MAWP used to calculate the MAWA
is determined by Your Age at the time You first take a Withdrawal from Your
Contract.

You may withdraw up to the MAWA throughout each Benefit Year without impacting
the annual amount guaranteed for Withdrawal under the GMWB. If You do not
withdraw the entire MAWA in a Benefit Year, You may not carry over any unused
MAWA to any subsequent Benefit Year. In addition Your MAWA for the next Benefit
Year will not be recalculated as a result of taking less than the entire MAWA in
any given Benefit Year.

Withdrawals made under the GMWB are treated like any other Withdrawal under the
Contract for purposes of calculating Contract Value, charges, including
Withdrawal Charges, fees, applicable taxes, and any other benefits under the
Contract.

Increases and decreases in the Benefit Base impact Your MAWA as follows:

INCREASES IN THE BENEFIT BASE
The Benefit Base is increased when an Eligible Purchase Payment is allocated to
Your Contract. If the Benefit Base is increased for Eligible Purchase Payments,
the MAWA will be recalculated upon receipt of the Eligible Purchase Payments by
multiplying the increased Benefit Base by the applicable MAWP. In any Benefit
Year when Eligible Purchase Payments are allocated to Your Contract, any
remaining Withdrawals of MAWA will be based on the increased MAWA. If the
Benefit Base is increased on a Benefit Year anniversary, the MAWA will be
recalculated on that Benefit Year anniversary by multiplying the increased
Benefit Base by the applicable MAWP. The GMWB charge on and after that Benefit
Year anniversary is assessed on the increased Benefit Base.

DECREASES IN THE BENEFIT BASE
Excess Withdrawals reduce Your Benefit Base. Any Excess Withdrawal in a Benefit
Year reduces the Benefit Base in the same proportion by which the Contract Value
is reduced by the Excess Withdrawal. When the Contract Value is less than or
equal to the Benefit Base, Excess Withdrawals will result in a reduction of the
Benefit Base which is greater than the amount of the Excess Withdrawal. As a
result of reduction of the Benefit Base, the MAWA will also be reduced. The new
MAWA will equal the reduced Benefit Base multiplied by the applicable MAWP. The
recalculated MAWA is available for Withdrawal at the beginning of the next
Benefit Year and will be lower than Your previously calculated MAWA.

If You are taking Required Minimum Distributions ("RMD") from the Contract to
which this Endorsement is attached, and the RMD amount based only on the
Contract is greater than the MAWA in any given Benefit Year, no portion of the
RMD Withdrawal will be treated as an Excess Withdrawal. Any portion of a
Withdrawal that is greater than either the MAWA or the RMD amount based only on
the Contract to which this Endorsement is attached will be considered an Excess
Withdrawal.

IF YOUR CONTRACT VALUE IS REDUCED TO ZERO
If Your Contract Value is reduced to zero and the Benefit Base is greater than
zero, a benefit remains payable under this Endorsement, but all other benefits
under the Contract, including Death Benefits, will no longer be available.
However, if Your Contract Value is reduced to zero because of an Excess
Withdrawal, no further benefits will be payable under this Endorsement or the
Contract.

When the Contract Value equals zero and the Benefit Base is greater than zero,
any remaining benefit under this Endorsement must be taken through one of the
following income options:

    1. The current MAWA, divided equally and paid on a quarterly, semi-annual
       or annual frequency as selected by You until the date of Your death(s);
       or

    2. Any payment option mutually agreeable between You and Us.

Once You elect an income option, it cannot be changed.

If You do not select a payment option, the remaining benefit will be paid as the
current MAWA on a quarterly basis until the date of Your death(s).

                                       4

<PAGE>

EXTENSION OF THE BENEFIT BASE EVALUATION PERIOD ("EXTENSION")
We may offer You Extension(s) of the Benefit Base Evaluation Period at the end
of the current Benefit Base Evaluation Period, provided You are age 85 or
younger at that time. If You elect such an Extension, You will receive a new
Endorsement with the GMWB Charge and provisions in effect at that time.

LATEST ANNUITY DATE
If there is remaining Contract Value and the Benefit Base is greater than zero
on the Latest Annuity Date, You must select one of the options listed below.

    1. Annuitize the Contract Value under the Annuity Provisions of the
       Contract; or

    2. Elect to receive the current MAWA as of the Latest Annuity Date in the
       form of a payment option, divided equally and paid on a quarterly,
       semi-annual or annual frequency as selected by You until the date of
       Your death; or

    3. Any payment option mutually agreeable between You and Us.

If You do not select an option listed above, on the Latest Annuity Date We will
annuitize the Contract Value under the Annuity Provisions of the Contract,
Options 3 and 3V with 120 Monthly Payments Guaranteed or payments that do not
exceed Your life expectancy as required by the IRS.

INVESTMENT OPTIONS
If the Bonus is elected, We will restrict allocations to the Variable Portfolios
or available Fixed Account Option(s). We will not allow transfers or Purchase
Payment(s) to be allocated into any of the restricted investment option(s) or in
any way that is outside the established restrictions. Established restrictions
are shown on the Application/Enrollment Form. Further, We will require
enrollment in a quarterly automatic asset rebalancing program. We will notify
You if investment restrictions change.

TERMINATION OF WITHDRAWALS OVER TWO LIVES
If there are two Covered Persons, Withdrawals guaranteed for the life of one of
the Covered Persons will terminate if:

    1. One of the two Covered Persons is removed from the Endorsement due to an
       ownership change; or

    2. The Covered Persons are no longer married at the time of death of the
       first Covered Person.

Termination of Withdrawals guaranteed for the life of one Covered Person does
not impact any other terms and conditions of this Endorsement.

TERMINATION OF THE GMWB
Once elected, this Endorsement maybe terminated and deduction of any
corresponding GMWB Charge will end after the termination date. You may terminate
the Endorsement if Your termination request is received:

    1. Through the 5th Benefit Year anniversary, the termination is effective
       on the 5th Benefit Year anniversary;

    2. After the 5th and through the 10th Benefit Year anniversary, the
       termination is effective on the 10th Benefit Year anniversary;

    3. In any Benefit Year after the 10th Benefit Year anniversary, the
       termination is effective on the Benefit Year anniversary following Our
       receipt of the election to terminate this Endorsement.

On the Benefit Year anniversary when termination occurs the GMWB Charge will be
deducted.

This Endorsement and the related charge will terminate automatically if:

    1. The Covered Person dies, or if there were two Covered Persons, upon
       the death of the surviving Covered Person; or,

    2. A Death Benefit is paid and the Contract is terminated; or,

    3. The Contract is annuitized; or

    4. Excess Withdrawals reduce the Contract Value to zero; or

    5. Any change that removes all Covered Persons; or

    6. The Contract is terminated for any reason.

If terminated for any reason, the GWMB may not be re-elected or reinstated.

DEATH OF COVERED PERSON(s)
If there is one Covered Person, then upon the death of the Covered Person, this
Endorsement and corresponding charge are terminated.

indirectly controlling or controlled by or under direct or indirect common
control with such specified person. For the purposes of this definition,
"control" when used with respect to any specified person means the power to
direct or cause the direction of the management and policies of such person,
directly or indirectly, whether through the ownership of voting securities, by
contract or otherwise; and the terms "controlling," "controlled" and "under
common control with" have meanings correlative to the foregoing.

     "Applicable Procedures" means, with respect to any transfer or transaction
involving a Global Security or beneficial interest therein, the rules and
procedures of the Depositary for such Security, in each case to the extent
applicable to such transaction and as in effect from time to time.

     "Bankruptcy Law" means Title 11 of the United States Code (or any successor
thereto) or any similar federal or state law for the relief of debtors.

     "Bid Solicitation Agent" means the agent of the Company appointed to obtain
quotations for the Securities as set forth under the definition of Trading
Price, which such agent shall initially be the Trustee and shall at no time be
an Affiliate of the Company. The Company may, from time to time, change the Bid
Solicitation Agent.

     "Board of Directors" means either the board of directors of the Company or
any duly authorized committee of such board.

     "Board Resolution" means a resolution of the Board of Directors.

     "Business Day" means any day, other than a Saturday or Sunday, that is

required by law, regulation or executive order to close in The City of New York
or place of payment.

     "Capital Stock" of any Person means any and all shares, units, interests,
participations, rights in or other equivalents (however designated) of such
Person's capital stock, other equity interests whether now outstanding or issued
after the date of this Indenture, partnership interests (whether general or
limited), limited liability company interests, any other interest or
participation that confers on a Person the right to receive a share of the
profits and losses of, or distributions of assets of, the issuing Person,

convertible into Capital Stock), warrants or options exchangeable for or
convertible into such Capital Stock.

     "Change of Control" means the occurrence of any of the following events:

     (i) the direct or indirect sale, lease, transfer, conveyance or other

properties or assets of the Company and its Subsidiaries, taken as a whole, to
any "person" (as that term is used in Section 13(d) of the Exchange Act);

     (ii) the adoption of a plan relating to the liquidation or dissolution of
the Company;

     (iii) the consummation of any transaction (including, without limitation,

of the Company, measured by voting power rather than number of shares;

     (iv) the Company consolidates with or merges with or into any Person, or
any such Person consolidates with or merges into or with the Company, in any
such event pursuant to a transaction in which the outstanding Voting Stock of
the Company is converted into or exchanged for cash, securities or other

     Section 1.05 Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an 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,
where it is hereby expressly required, to the Company, as described in Section
13.02. 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 1.05.

     (b) The fact and date of the execution by any person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to 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.

     (c) The principal amount and serial number of any Security and the
ownership of Securities shall be proved by the register for the Securities.

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

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

                                 THE SECURITIES

     Section 2.01 Form and Dating.

     (a) The Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibits A and B, which are a part of this
Indenture. The Securities may have notations, legends or endorsements required
by law, stock exchange rule or usage (provided that any such notation, legend or
endorsement required by usage is in a form acceptable to the Company). The
Company shall provide any such notations, legends or endorsements to the Trustee
in writing. Each Security shall be dated the date of its authentication. The
Securities may, but need not, have the corporate seal of the Company or a
facsimile thereof affixed thereto or imprinted thereon.

     (b) Global Securities. All of the Securities are initially being offered
and sold to qualified institutional buyers as defined in Rule 144A
(collectively, "QIBs" or individually, each a "QIB") in reliance on Rule 144A
under the Securities Act and Global Securities shall be issued initially in the
form of a Restricted Global Security (until such time as the Securities shall be
registered pursuant to the Registration Rights Agreement), which shall be
deposited with the Trustee at its Corporate Trust Office, as custodian for the
Depositary (as defined below) and registered in the name of The Depository Trust
Company ("DTC") or the nominee thereof (DTC, or any successor thereto, and any
such nominee being hereinafter referred to as the "Depositary"), duly executed
by the Company and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount 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.

     (c) Global Securities in General. Each Global Security shall represent such
of the outstanding Securities as shall be specified therein and each shall
provide that it shall represent the aggregate amount of outstanding Securities
from time to time endorsed thereon and that the aggregate 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 required by Section 2.12 hereof, and
shall be made on the records of the Trustee and the Depositary.

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

     The Company shall execute and the Trustee shall, in accordance with this
Section 2.01(d), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depositary or a
nominee thereof, (b) shall be delivered by the Trustee to the Depositary or held
by the Trustee pursuant to the Depositary's instructions and (c) shall be
substantially in the form of Exhibit A attached hereto.

     (e) Certificated Securities. Securities not issued as interests in the
Global Securities shall be issued in certificated form substantially in the form
of Exhibit B attached hereto.

                                       13

<PAGE>

     Section 2.02 Execution and Authentication.

     The Securities shall be executed on behalf of the Company by one Officer.
The signature of such Officer on the Securities may be manual or facsimile.

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

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

     The Trustee shall authenticate and deliver the Securities for original
issue in an aggregate principal amount of up to $135 million upon one or more
Company Orders without any further action by the Company (other than as
contemplated in Section 13.03, Section 13.04 and Section 13.05 hereof). The
aggregate principal amount of the Securities due at the Stated Maturity thereof
outstanding at any time may not exceed the amount set forth in the foregoing
sentence.

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

     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 purchase or payment ("Paying
Agent") and an office or agency where Securities may be presented for conversion
("Conversion Agent"). The Registrar shall keep a register of the Securities and
of their transfer and exchange. The Company may have one or more co-registrars,
one or more additional paying agents and one or more additional conversion
agents. The term Paying Agent includes any additional paying agent, including
any named pursuant to Section 4.07. The term Conversion Agent includes any
additional conversion agent, including any named pursuant to Section 4.07.

     The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-registrar (in each case, if such
Registrar, agent or co-registrar is a Person other than the Trustee). The
agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall promptly 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
Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar,
Conversion Agent or co-registrar.

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

                                       14

<PAGE>

     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
payments in respect of any Security, the Company shall deposit with the Paying
Agent a sum of money (in immediately available funds if deposited on the due
date) or shares of Common Stock sufficient to make such payments when so
becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money and shares of Common Stock
held by the Paying Agent for the making of payments in respect of the Securities
and shall promptly 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 shares of Common Stock so held in trust. If the
Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it
shall segregate the money and shares of 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 shares of Common Stock held by it to the
Trustee and to account for any funds and Common Stock disbursed by it. Upon
doing so, the Paying Agent shall have no further liability for the money or
shares of Common Stock.

     Section 2.05 Securityholder Lists.

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

     Section 2.06 Transfer and Exchange.

     (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 Securityholder or such
Securityholder's attorney duly authorized in writing, at the office or agency of
the Company designated as Registrar or co-registrar pursuant to Section 2.03,
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. 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
Securityholder requesting such transfer or exchange.

     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 Securityholder or such Securityholder's attorney duly authorized in writing,
at such office or agency. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

     The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of Securities selected for redemption (except,
in the case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities in respect of which a Repurchase Notice or
Fundamental Change Repurchase Notice has been given and not withdrawn by the
Holder thereof in

                                       15

<PAGE>

accordance with the terms of this Indenture (except, in the case of Securities
to be purchased in part, the portion thereof not to be purchased) or any
Securities for a period of 15 days before the mailing of a notice of redemption
of Securities to be redeemed.

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

     (d) Except as otherwise set forth in this Indenture, any such action taken
by a Holder shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is
made upon such Security or any Security issued in exchange or substitution
therefor.

     (e) 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.

     (f) 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.

     Section 2.07 Replacement Securities.

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

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

     Upon the issuance of any new Securities under this Section 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 lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
contractual obligation of the Company, whether or not the

                                       16

<PAGE>

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

     The provisions of this Section 2.07 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.08 Outstanding Securities; Determinations of Holders' Action.

     Securities outstanding at any time are all the Securities authenticated by
the Trustee except for those cancelled by it, those redeemed or purchased
pursuant to Section 2.07, 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, a Guarantor or an Affiliate thereof 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 Act
hereunder, Securities owned by the Company or any other obligor upon the
Securities, a Guarantor or any Affiliate of the Company or such other obligor or
Guarantor shall be disregarded and deemed not to be outstanding, except that, in
determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent, waiver or other act,
only Securities which a Responsible Officer of the Trustee actually knows to be
so owned shall be so disregarded. Subject to the foregoing, only Securities
outstanding at the time of such determination shall be considered in any such
determination (including, without limitation, determinations pursuant to Article
6 and Article 9).

     If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it 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, or on the Business Day immediately following a Repurchase Date
or a Fundamental Change Repurchase Date, or on Stated Maturity, money or
securities, if permitted hereunder, sufficient to pay Securities payable on that
date, then from and after such Redemption Date, Repurchase Date, Fundamental
Change Repurchase Date or Stated Maturity, as the case may be, such Securities
shall cease to be outstanding and Interest and Additional Interest, if any, on
such Securities shall cease to accrue and the rights of the Holders therein
shall terminate whether or not the Securities are surrendered to the Paying
Agent (by effecting book entry transfer of the Securities or delivering
Certificated Securities), other than the right to receive such payment upon such
surrender; 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 from and
after the time of conversion on the date of conversion, such Security shall
cease to be outstanding and Interest and Additional Interest, if any, shall
cease to accrue and the rights of the Holders therein shall terminate (other
than the right to receive the Conversion Settlement Distribution).

     Section 2.09 Temporary Securities.

     Pending the preparation of Certificated Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the Certificated Securities in lieu of which they are issued and with
such appropriate insertions,

                                       17

<PAGE>

omissions, substitutions and other variations as the Officers executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities.

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

     Section 2.10 Cancellation.

     All Securities surrendered for payment, purchase by the Company pursuant to
Article 3, conversion, redemption or registration of transfer or exchange shall,
if surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the
Trustee. The Company may not issue new Securities to replace Securities it has
paid or delivered to the Trustee for cancellation other than in connection with
registrations of transfer or exchange or that any Holder has converted pursuant
to Article 10. No Securities shall be authenticated in lieu of or in exchange
for any Securities cancelled as provided in this Section 2.10, except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with the Trustee's
customary procedure.

     Section 2.11 Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of the principal amount of the Security or
any portion thereof, or the payment of any Redemption Price, Repurchase Price or
Fundamental Change Repurchase Price in respect thereof, and Interest or
Additional Interest thereon, for the purpose of conversion and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     Section 2.12 Global Securities.

     (a) Notwithstanding any other provisions of this Indenture or the
Securities, (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) below, (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)(ii) below and
Section 2.12(e) below, and (C) transfers of a Certificated Security shall comply
with Section 2.06, Section 2.12(a)(iii) and Section 2.12(a)(iv) 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, and no such transfer to any such other Person may be
registered; provided that this Section 2.12(a)(i) shall not prohibit any
transfer of a Security that is issued in exchange for a Global Security but is
not itself a Global Security. No transfer of a Security to any Person shall be
effective under this Indenture or the Securities unless and

                                       18

<PAGE>

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.

     (ii) Restrictions on Transfer of a Beneficial Interest in a Global Security
for a Certificated Security. A beneficial interest in a Global Security may not
be exchanged for a Certificated Security except upon satisfaction of the
requirements set forth in this paragraph below and in Section 2.12(e) below.
Upon receipt by the Trustee of a request to transfer a beneficial interest in a
Global Security in accordance with Applicable Procedures for a Certificated
Security in the form satisfactory to the Trustee, together with written
instructions to the Trustee to make, or direct the Registrar to make, an
adjustment on its books and records with respect to such Global Security to
reflect a decrease in the aggregate principal amount of the Securities
represented by the Global Security, such instructions to contain information
regarding the Depositary account to be decreased, then the Trustee shall cause,
or direct the Registrar to cause, in accordance with the standing instructions
and procedures existing between the Depositary and the Registrar, the aggregate
principal amount of the Securities represented by the Global Security to be
decreased by the aggregate principal amount of the Certificated Security to be
issued, shall issue such Certificated Security and shall debit or cause to be
debited to the account of the person specified in such instructions a beneficial
interest in the Global Security equal to the principal amount of the
Certificated Security so issued.

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

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

          (z) 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 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.

     (iv) Restrictions on Transfer or Exchange of a Certificated Security for a
Beneficial Interest in a Global Security. A Certificated Security may not be
transferred or exchanged for a beneficial interest in a Global Security except
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 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 equal to the principal amount of the Certificated Security so
cancelled. If no Global Securities are then outstanding, the Company shall issue
and the Trustee shall authenticate, upon written order of the Company in the
form of an Officer's Certificate, a new Global Security in the appropriate
principal amount.

     (b) [Reserved].

     (c) [Reserved].

     (d) [Reserved].

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

     (i) Notwithstanding any other provisions of this Indenture or the
Securities, a Global Security shall not be exchanged in whole or in part for a
Security registered in the name of any Person other than the Depositary or one
or more nominees thereof, provided that a Global Security may be exchanged for
Securities registered in the names of any Person designated by the Depositary in
the event that (i) the Depositary has notified the Company that it is unwilling
or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a "clearing agency" registered under Exchange Act, and a
successor Depositary is not appointed by the Company within 90 days (ii) the
Company determines at any time that the Securities shall no longer be
represented by Global Securities and shall inform such Depositary of such
determination in writing and participants in such Depositary elect to withdraw
their beneficial interests in the Global Securities from such Depositary,
following notification by the Depositary of their right to do so or (iii) an
Event of Default has occurred and is continuing. Any Global Security exchanged
pursuant to clause (i) above shall be so exchanged in whole and not in part, and
any Global Security exchanged pursuant to clauses (ii) or (iii) above may be
exchanged in whole or from time to time in part as directed by the Depositary.
Any Security issued in exchange for a Global Security or any portion thereof
shall be a Global Security; provided that any such Security so issued that is
registered in the name of a person other than the Depositary or a nominee
thereof or any successor of either of the foregoing pursuant to this paragraph
shall not be a Global Security.

     (ii) Securities issued in exchange for a Global Security or any portion
thereof shall be issued in definitive, fully registered form, 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 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 or its nominee 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.

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

     (iv) In the event of the occurrence of any of the events specified in
clause (i) above, the Company shall promptly make available to the Trustee a
reasonable supply of Certificated Securities in definitive, fully registered
form.

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

                                       20

<PAGE>

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

     (vi) Except as expressly set forth in this Indenture, including Sections
2.12(a)(ii) and 2.12(e), none of the Trustee, any Paying Agent, Conversion
Agent, the Company or the Registrar shall have any responsibility or obligation
to any beneficial owner in the Global Securities, a member of, or a participant
in the Depositary or other Person with respect to the accuracy of the records of
the Depositary or its nominee or of any participant or member thereof, with
respect to any ownership interest in the Global Securities or with respect to
the delivery to any participant, member, beneficial owner or other Person (other
than the Depositary) of any notice (including any notice of redemption) or the
payment of any amount, under or with respect to such Global Securities. All
notices and communications to be given to the Holders and all payments to be
made to Holders under the Securities shall be given or made only to or upon the
order of the registered Holders (which shall be, in the case of a Global
Security, the Depositary or its nominee). The rights of beneficial owners in the
Global Securities shall be exercised only through the Depositary subject to the
applicable rules and procedures of the Depositary. Other than as set forth in
this Indenture, the Trustee, any Paying Agent, the Conversion Agent, the Company
and the Registrar may rely and shall be fully protected in relying upon
information furnished by the Depositary with respect to its members,
participants and any beneficial owners. Except as expressly set forth in this
Indenture, including Sections 2.12(a)(ii) and 2.12(e), the Trustee, each Paying
Agent, the Conversion Agent, the Company and the Registrar shall be entitled to
deal with any depositary (including the Depositary), and any nominee thereof,
that is the Holder of any Global Securities as a Holder for all purposes of this
Indenture relating to such Global Securities (including the payment of
principal, Interest and Additional Interest, if any, and the giving of
instructions or directions by or to the owner or Holder of a beneficial
ownership interest in such Global Securities) as the sole Holder of such Global
Securities and shall have no obligations to the beneficial owners thereof. None
of the Trustee, any Paying Agent, the Conversion Agent, the Company or the
Registrar shall have any responsibility or liability for any acts or omissions
of any such depositary with respect to such Global Securities, for the records
of any such depositary, including records in respect of beneficial ownership
interests in respect of any such Global Securities, for any transactions between
such depositary and any participant in such depositary or between or among any
such depositary, any such participant and/or any holder or owner of a beneficial
interest in such Global Securities or for any transfers of beneficial interests
in any such Global Securities.

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

     The Trustee shall have no responsibility for the actions or omissions of
the Depositary, or the accuracy of the books and records of the Depositary.

                                       21

     Section 2.13 CUSIP Numbers.

     The Company may issue the Securities with one or more "CUSIP," "ISIN" or
other similar numbers (if then generally in use), and, if so, the Trustee shall
use "CUSIP," "ISIN" or other similar numbers in notices of redemption as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption or purchase 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 of
any change in the CUSIP, ISIN or other similar numbers.

                                    ARTICLE 3
                           REDEMPTION AND REPURCHASES

     Section 3.01 Company's Right to Redeem; Notices to Trustee.

     Prior to February 6, 2012, the Securities shall not be redeemable at the
Company's option. On or after February 6, 2012 through and including February 1,
2017, the Company, at its option, may redeem the Securities for U.S. legal
tender ("cash"), in whole or in part, at a redemption price (the "Redemption
Price") equal to 100% of the principal amount of the Securities redeemed, plus
any accrued and unpaid Interest and accrued and unpaid Additional Interest, if
any, on the Securities redeemed up to, but not including, the Redemption Date if
the Last Reported Sale Price of the Common Stock for at least 20 Trading Days
during the period of 30 consecutive Trading Days ending on the last Trading Day
is more than 130% of the Conversion Price in effect on such last Trading Day
(such last Trading Day being no later than February 1, 2017). On or after
February 1, 2017, the Company, at its option, may redeem the Securities for cash
at any time, in whole or in part, at a Redemption Price equal to 100% of the
principal amount of the Securities redeemed, plus any accrued and unpaid
Interest and accrued and unpaid Additional Interest, if any, on the Securities
redeemed up to, but not including, the Redemption Date. If the Redemption Date
is on a date that is after an Interest Record Date and on or prior to the
corresponding Interest Payment Date, the Redemption Price shall be 100% of the
principal amount of the Securities redeemed but shall not include accrued and
unpaid Interest and accrued and unpaid Additional Interest, if any. Instead, the
Company shall pay such Interest and Additional Interest, if any, on the Interest
Payment Date to the Holder of record on the corresponding Interest Record Date.
If the Company elects to redeem Securities pursuant to this Section 3.01, it
shall notify the Trustee in writing of such election together with the
Redemption Date, the Conversion Rate, the principal amount of Securities to be
redeemed and the Redemption Price. Notwithstanding the foregoing, the Company
may not redeem the Securities if it has failed to pay any Interest, including
Additional Interest, if any, on the Securities when due and such failure is
continuing.

     The Company shall give the notice to the Trustee provided for in this
Section 3.01 by a Company Order, at least 45 days but not more than 75 days
before the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee).

     Section 3.02 Selection of Securities to Be Redeemed.

     If less than all of the Securities are to be redeemed, unless the
procedures of the Depositary provide otherwise, the Trustee shall select the
Securities to be redeemed by lot, on a pro rata basis or by another method the
Trustee considers fair and appropriate (so long as such method is not prohibited
by the rules of any stock exchange or quotation association on which the
Securities are then traded or quoted). The Trustee may select for redemption
portions of the principal amount of Securities that have denominations larger
than $1,000.

                                       22

<PAGE>

     Securities and portions of Securities that the Trustee selects shall be in
principal amounts of $1,000 or an integral multiple of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of the Securities selected to be
redeemed and, in the case of any Securities selected for partial redemption, the
method it has chosen for the selection of the Security.

     Following a notice of redemption, Securities and portions of Securities
that have been called for redemption are convertible, pursuant to Section
10.01(a)(2), by the Holder until the close of business on the second Business
Day prior to the Redemption Date. If any Security selected for partial
redemption is converted in part before termination of the conversion right with
respect to the portion of the Security so selected, the converted portion of
such Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities that have been converted during a selection of Securities
to be redeemed may be treated by the Trustee as outstanding for the purpose of
such selection.

     Section 3.03 Notice of Redemption.

     At least 30 days but not more than 60 days before a Redemption Date, the
Company shall deliver a notice of redemption (substantially in the form of
Exhibit C) to each Holder of Securities to be redeemed.

     The notice shall identify the Securities to be redeemed and shall state
(along with any other information the Company wishes to include):

     (i) the Redemption Date;

     (ii) the Redemption Price;

     (iii) the Conversion Rate;

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

     (v) that Securities that have been called for redemption may be converted
at any time before the close of business on the second Business Day prior to the
Redemption Date;

     (vi) that Securities called for redemption and not converted shall be
redeemed on the Redemption Date;

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

     (viii) that Securities called for redemption must be surrendered to the
Paying Agent (by effecting book entry transfer of the Securities or delivering
Certificated Securities, together with necessary endorsements, as the case may
be) to collect the Redemption Price;

     (ix) 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;

     (x) that, unless the Company defaults in making payment of such Redemption
Price, Interest and Additional Interest, if any, on the Securities called for
redemption shall cease to accrue from and after the Redemption Date; and

                                       23

<PAGE>

     (xi) the "CUSIP," "ISIN" or other similar number(s), as the case may be, of
the Securities being redeemed.

     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 seven Business Days (or such shorter period as may
be satisfactory to the Trustee) prior to the date by which such notice of
redemption must be given to Holders in accordance with this Section 3.03.

     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 except for Securities that 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 and from and after the
Redemption Date (unless the Company shall default in the payment of the
Redemption Price) such Securities shall cease to bear Interest and Additional
Interest, if any, and the rights of the Holders therein shall terminate (other
than the right to receive the Redemption Price).

     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 Subsidiary
or an Affiliate of either of them is the Paying Agent, shall segregate and hold
in trust) money sufficient to pay the Redemption Price of all Securities to be
redeemed on that date other than Securities or portions of Securities called for
redemption which on or prior thereto have been delivered by the Company to the
Trustee for cancellation or have been converted. The Paying Agent shall as
promptly as practicable return to the Company any money not required for that
purpose because of conversion of Securities pursuant to Article 10. If such
money is then held by the Company or a Subsidiary or an Affiliate of either in
trust and is not required for such purpose it shall be discharged from such
trust.

     Section 3.06 Securities Redeemed in Part.

     Upon surrender of a Security that is redeemed in part, the Company shall
execute and the Trustee shall, without charge, 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.

     Section 3.07 Repurchase of Securities by the Company at Option of the
Holder.

     (a) On each of February 1, 2017 and February 1, 2022 (each, a "Repurchase
Date"), each Holder shall have the option to require the Company to repurchase
Securities for which that Holder has properly delivered and not withdrawn a
written Repurchase Notice (as defined below) at a repurchase price in cash equal
to 100% of the principal amount of those Securities, plus accrued and unpaid
Interest and accrued and unpaid Additional Interest, if any, on those
Securities, to, but not including, such Repurchase Date (the "Repurchase
Price"); provided that if the Repurchase Date is on a date that is after an
Interest Record Date and on or prior to the corresponding Interest Payment Date,
the Repurchase Price shall be 100% of the principal amount of the Securities
repurchased but shall not include accrued and unpaid Interest and accrued and
unpaid Additional Interest, if any. Instead, the Company shall pay such accrued
and unpaid Interest and Additional Interest, if any, on the Interest Payment
Date, to the Holder of Record on the corresponding Interest Record Date. Not
later than 25 Business Days prior to any Repurchase Date, the Company shall
deliver a Company Notice (substantially in the form of Exhibit D) to

                                       24

<PAGE>

the Trustee and to each Holder. The Company Notice shall include a form of
Repurchase Notice to be completed by a Holder and shall state:

     (i) the Repurchase Date, the Repurchase Price and the Conversion Rate;

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

     (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 terms 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 (by effecting
book entry transfer of the Securities or delivering Certificated Securities,
together with necessary endorsements, as the case may be) to collect payment;

     (v) that the Repurchase Price for any security as to which a Repurchase
Notice has been given and not withdrawn shall be paid promptly following the
later of the Business Day immediately following the Repurchase Date and the time
of surrender of such Security as described in clause (iv) above;

     (vi) the procedures the Holder must follow to exercise its right to require
the Company to repurchase such Holder's Securities under this Section 3.07 and a
brief description of that right;

     (vii) briefly, the conversion rights, if any, that exist at the date of the
Company Notice or as a result of the Company Notice with respect to 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 or Additional Interest,
if any, on such Securities shall cease to accrue from and after the Repurchase
Date; and

     (x) the "CUSIP," "ISIN" or other similar number(s), as the case may be, of
the Securities.

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

     (b) A Holder may exercise its rights specified in Section 3.07(a) upon
delivery to the Paying Agent of a written notice of repurchase (a "Repurchase
Notice") during the period beginning at any time from the opening of business on
the date that is 25 Business Days prior to the relevant Repurchase Date until
the close of business on the second Business Day prior to such Repurchase Date,
stating:

     (i) if Certificated Securities have been issued, the certificate number(s)
of the Securities which the Holder shall deliver to be repurchased or, if
Certificated Securities have not been issued for such Security, the Repurchase
Notice shall comply with the appropriate Depositary procedures for book-entry
transfer,

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

                                       25

<PAGE>

     (iii) that such Security shall be repurchased by the Company as of the
Repurchase Date pursuant to the terms and conditions specified in Section 5 of
the Securities and in this Indenture.

     The delivery of such Security (together with all necessary endorsements or
notifications of book entry transfer) to the Paying Agent at any time after
delivery of the Repurchase Notice at the offices of the Paying Agent shall be 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 (together with all necessary endorsements or
notifications of book entry transfer) so delivered to the Paying Agent shall
conform in all respects to the description thereof in the related Repurchase
Notice.

     The Company shall repurchase from the Holder thereof, pursuant to and
subject to the terms and conditions of 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 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 3.07 shall be consummated by the delivery of the consideration to
be received by the Holder promptly following the later of the Business Day
immediately following the Repurchase Date and the time of delivery of the
Security (together with all necessary endorsements or notifications of
book-entry transfer).

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Repurchase Notice contemplated by this Section 3.07 shall
have the right to withdraw such Repurchase Notice by delivery of a written
notice of withdrawal to the Paying Agent in accordance with Section 3.09 at any
time prior to the close of business on the second Business Day prior to the
Repurchase Date.

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

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

     (a) If a Fundamental Change occurs, each Holder shall have the right, at
such Holder's option, to require the Company to repurchase for cash all of such
Holder's Securities not previously called for redemption by the Company, or any
portion thereof that is equal to or an integral multiple of $1,000 principal
amount, at a repurchase price equal to 100% of the principal amount of those
Securities, plus accrued and unpaid Interest and accrued and unpaid Additional
Interest, if any, on those Securities (the "Fundamental Change Repurchase
Price") to, but not including, the date that is specified by the Company and is

Fundamental Change mailed by the Company pursuant to Section 3.08(b) (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); provided that if
the Fundamental Change Repurchase Date is on a date that is after an Interest
Record Date and on or prior to the corresponding Interest Payment Date, the
Fundamental Change Repurchase Price shall be 100% of the principal amount of the
Securities repurchased but shall not include accrued and unpaid Interest and
accrued and unpaid Additional Interest, if any. Instead, the Company shall pay
such Interest and Additional Interest, if any, on the Interest Payment Date to
the Holder of Record on the corresponding Interest Record Date.

     (b) No later than 15 days after the occurrence of a Fundamental Change, the
Company shall deliver a Company Notice of the Fundamental Change (substantially
in the form of Exhibit E) to the Trustee and to each Holder. The Company Notice
shall include a form of Fundamental Change Repurchase Notice to be completed by
the Holder and shall state:

     (viii) that the Securities must be surrendered to the Paying Agent (by
effecting book entry transfer of the Securities or delivering Certificated
Securities, together with necessary endorsements, as the case may be) to collect

Securities surrendered for purchase by the Company shall cease to accrue from
and after the Fundamental Change Repurchase Date; and

     (xiv) the "CUSIP," "ISIN" or other similar number(s), as the case may be,

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

     (c) A Holder may exercise its rights specified in this Section 3.08 upon

     number(s) of the Securities which the Holder shall deliver to be
     repurchased or, if Certificated Securities have not been issued, the
     Fundamental Change Repurchase Notice shall comply with the appropriate
     Depositary procedures for book-entry transfer;

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

          (iii) that such Security shall be repurchased pursuant to the terms
     and conditions specified in Section 5 of the Securities and in this
     Indenture.

     The delivery of such Security (together with all necessary endorsements or
notification of book-entry transfer) to the Paying Agent with the Fundamental
Change Repurchase Notice 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 (together with all
necessary endorsements or notification of book-entry transfer) so delivered to
the Paying Agent shall conform in all 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 Fundamental Change
Repurchase Price promptly following the later of the Business Day following the
Fundamental Change Repurchase Date or the time of delivery of such Security
(together with all necessary endorsements or notifications of book-entry
transfer).

     Notwithstanding the foregoing, Holders shall not have the right to require
the Company to repurchase the Securities upon a Fundamental Change as a result
of a Change of Control described in clause (4) of the definition thereof if 90%
or more of the consideration in the transaction or transactions constituting
such Change of Control consists of shares of common stock traded or to be traded
immediately following such Change of Control on a U.S. national securities
exchange or The New York Stock Exchange, and, as a result of such transaction or
transactions, the Securities become convertible into such common stock (and any
rights attached thereto).

     Notwithstanding anything herein to the contrary, any Holder delivering to
the Paying Agent the Fundamental Change Repurchase Notice contemplated by this
Section 3.08(c) shall have the right to withdraw such Fundamental Change
Repurchase Notice by delivery of a written notice of withdrawal to the Paying
Agent in accordance with Section 3.09 at any time prior to the close of business
on the second Business Day prior to the Fundamental Change Repurchase Date.

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

the original Repurchase Notice or Fundamental Change Repurchase Notice, as the
case may be, and which has been or shall be delivered for purchase by the
Company,

     (ii) if Certificated Securities have been issued, the certificate number,

agency for all of the aforesaid purposes. The Company shall give prompt written
notice to the Trustee of the location, and of any change in the location, of any
such office or agency (other than a change in the location of the office of the
Trustee). If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 13.02.

     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 4.08 No Layering of Indebtedness.

     The Company shall not incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is contractually subordinate or junior
in right of payment to any Senior Debt of the Company and senior in right of
payment to the Securities. In addition, no Guarantor shall incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness of such
Guarantor that is contractually subordinate or junior in right of payment to any
Indebtedness of such Guarantor and senior in right of payment to the Guarantee
of such Guarantor of the Securities. For purposes of this Section 4.08, Section
11.01 and Section 12.02, for the avoidance of doubt, no Indebtedness shall be
deemed to be subordinated in right of payment to any other Indebtedness solely
by virtue of being unsecured or secured by a junior priority lien or by virtue
of the fact that the holders of such Indebtedness have entered into
intercreditor agreements or other arrangements giving one or more of such
holders priority over the other holders in the collateral held by them or by
virtue of structural subordination.

     Section 4.09 Guarantees.

     (a) If the Company or any of its Subsidiaries acquires or creates another
Domestic Subsidiary after the date of this Indenture and such Domestic
Subsidiary becomes a guarantor or obligor in respect of other Indebtedness of
the Company or any of its Subsidiaries that is incurred, issued or raised in a
public or private U.S. capital markets transaction, then the Company will cause
that newly acquired or created Domestic Subsidiary to execute a Guarantee
pursuant to a supplemental indenture in the form of Exhibit G attached hereto or
as otherwise satisfactory to the Trustee and deliver an Opinion of Counsel to
the Trustee within 10 Business Days of the date on which it became a guarantor
or obligor of such Indebtedness to the effect that such supplemental indenture
has been duly authorized, executed and delivered by that Domestic Subsidiary and
constitutes a valid and binding agreement of that Domestic Subsidiary,
enforceable in accordance with its terms (subject to customary exceptions).

     (b) The Guarantee of any Domestic Subsidiary that becomes a Guarantor will
be released either with the consent of Holders of the Notes in accordance with
Section 9.02 hereof or without the consent of Holders of the Notes in accordance
with Section 12.07 hereof. The form of notation of Guarantee and the related
form of supplemental indenture are attached hereto as Exhibit F and Exhibit G,
respectively.

          (B) the resulting, surviving or transferee Person (the "successor
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 and the
successor Person (if not the Company) will expressly assume, by indenture
supplemental hereto, executed and delivered to the Trustee, in form reasonably
satisfactory to the Trustee, all of the obligations of the Company under the
Securities and this Indenture;

                                       33

<PAGE>

     (2) immediately after giving effect to such transaction, no Default or
Event of Default shall have occurred and be continuing; and

     (3) the Company shall have delivered to the Trustee an Officer's
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
relating to such transaction have been satisfied.

     (b) Each Guarantor will not, and the Company will not permit a Guarantor
to, consolidate with or merge with or into any other Person (other than the
Company or any Guarantor), unless:

     (1) Either

          (A) the Guarantor is the surviving Person in the case of a merger, or

          (B) the resulting, surviving or transferee Person (the "successor

of the United States of America, any State thereof or the District of Columbia
and the successor Guarantor Person (if not such Guarantor) will expressly

in form reasonably satisfactory to the Trustee, all of the obligations of such
Guarantor under the Securities and this Indenture;

     (2) immediately after giving effect to such transaction, no Default or

that such consolidation or merger and, if a supplemental indenture is required
in connection with such transaction, such supplemental indenture, comply with

such transaction have been satisfied.

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

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

Significant Subsidiary, of a petition or answer or consent seeking
reorganization or relief under any applicable Bankruptcy Law, or (iv) the
consent by the Company or any Significant Subsidiary to the filing of such
petition or to the appointment of or the taking possession by a custodian,
receiver, liquidator, assignee, trustee, sequestrator or other similar official
of the Company or any Significant Subsidiary or of any substantial part of any
of their property, or (v) the making by the Company or any Significant
Subsidiary, of a general assignment for the benefit of creditors, or the
admission by the Company or any Significant Subsidiary, in writing of its
inability to pay its debts generally as they become due; and

     (k) any Guarantee shall for any reason cease to be, or shall for any reason
be asserted in writing by any Guarantor or the Company not to be, in full force
and effect and enforceable in accordance with its terms, except to the extent
contemplated by this Indenture and any such Guarantee, including any release of
any Guarantee contemplated by this Indenture.

     The foregoing shall 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.

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

     Section 6.02 Acceleration.

     If an Event of Default (other than an Event of Default specified in Section
6.01(i) or Section 6.01(j) with respect to the Company) occurs and is continuing
(the Event of Default not having been cured or waived), the Trustee by notice to
the Company, or the Holders of at least 25% in aggregate principal amount of the
Securities at the time outstanding by notice to the Company and the Trustee, may
declare the principal amount of the Securities and any accrued and unpaid
Interest and any accrued and

                                       36

<PAGE>

unpaid Additional Interest, if any, on all the Securities to be immediately due
and payable. Upon such a declaration, such accelerated amount shall be
immediately due and payable. If an Event of Default specified in Section 6.01(i)
or Section 6.01(j) with respect to the Company occurs and is continuing, the
principal amount of the Securities and any accrued and unpaid Interest and any
accrued and unpaid Additional Interest, if any, on all the Securities shall
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Securityholders. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding, by notice
to the Trustee (and without notice to any other Securityholder) may rescind an
acceleration and its consequences, and thereby waive the Events of Default
giving rise to such 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 of the Securities and any
accrued and unpaid Interest and any accrued and unpaid Additional Interest, if
any, that have become due solely as a result of acceleration. No such rescission
shall affect any subsequent Event of 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 of the
Securities and any accrued and unpaid Interest and accrued and unpaid Additional
Interest, 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 the Trustee does not possess
any of the Securities or does not produce any of the Securities in the
proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative.

     Section 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 Securityholder), may waive any existing or past Default and its
consequences except (1) an Event of Default described in clauses (a), (b), (c),
(d), and (e) of Section 6.01 or (2) an Event of Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder affected. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or impair any
consequent right. This Section 6.04 shall be in lieu of Section 316(a)1(B) of
the TIA and such Section 316(a)1(B) is hereby expressly excluded from this
Indenture, as permitted by the TIA.

     Section 6.05 Control by Majority.

     The Holders of a majority in aggregate principal amount of the Securities
at the time outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee
determines is unduly prejudicial to the rights of other Securityholders or would
involve the Trustee in personal liability; provided, that the Trustee may take
any other action deemed proper by the Trustee which is not inconsistent with
such direction or this Indenture. Prior to taking any action under this
Indenture, the Trustee may require indemnity satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

     Section 6.06 Limitation on Suits.

     A Securityholder may not pursue any remedy with respect to this Indenture
or the Securities, except in case of a Default due to the non-payment of the
principal amount of the Securities, any accrued and unpaid Interest or any
accrued and unpaid Additional Interest, if any, unless:

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

     (ii) the Holders of at least 25% in aggregate principal amount of the
Securities at the time outstanding make a written request to the Trustee to
pursue the remedy;

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

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

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

     Section 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 of the Securities and any
accrued and unpaid Interest and any accrued and unpaid Additional Interest, if
any, in respect of the Securities held by such Holder, on or after the
respective due dates expressed in the 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 or the right to convert on or after such respective dates,
shall not be impaired or affected adversely without the consent of such Holder.

     Section 6.08 Collection Suit by Trustee.

     If an Event of Default described in Section 6.01 clauses (a) through (e)
(other than (b)) occurs and is continuing, the Trustee may recover judgment in
its own name and as trustee of an express trust against the Company for the
whole amount owing with respect to the Securities and the amounts provided for
in Section 7.07.

     Section 6.09 Trustee May File Proofs of Claim.

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

     (a) to file and prove a claim for the whole principal amount of the
Securities and any accrued and unpaid Interest and any accrued and unpaid
Additional Interest, if any, and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including
any

                                       38

<PAGE>

claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel or any other amounts due the Trustee under
Section 7.07) and of the Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or similar official in any
such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay the Trustee any amount
due it for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07.

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

     The Company agrees not to object to the Trustee participating as a member
of any official committee of creditors of the Company as it deems necessary or
advisable.

     Section 6.10 Priorities.

     Any money collected by the Trustee pursuant to this Article 6, and, after
an Event of Default, any money or other property distributable in respect of the
Company's obligations under this Indenture, shall be paid out in the following
order:

     FIRST: to the Trustee (including any predecessor Trustee) for amounts due
under Section 7.07;

     SECOND: to Securityholders for amounts due and unpaid on the Securities for
the principal amount of the Securities and any accrued and unpaid Interest and
any accrued and unpaid Additional Interest, if any, as the case may be, ratably,
without preference or priority of any kind, according to such amounts due and
payable on the Securities; and

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

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

     Section 6.11 Undertaking for Costs.

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

     Section 6.12 Waiver of Stay, Extension or Usury Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
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 or any usury or
other law wherever enacted, now or at any time hereafter in force, which would
prohibit or forgive the Company from paying all or any portion of the principal
amount of the Securities and any accrued and unpaid Interest and any accrued and
unpaid Additional Interest, if any, on Securities, as contemplated herein, or
which may affect the covenants or the performance of this Indenture; and the
Company (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it 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, and is actually
known to the Trustee, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs.

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

     (i) the Trustee need perform only those duties that are specifically set
forth in this Indenture and no others, and no implied duties, covenants or
obligations shall be read into this Indenture against the Trustee; and

     (ii) in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture, but in the case of any such
certificates or opinions which by any provision hereof are specifically required
to be furnished to the Trustee, the Trustee shall be under a duty to examine
such certificates and opinions to determine whether or not they conform to the
requirements of this Indenture, but need not confirm or investigate the accuracy
of mathematical calculations or other facts stated therein. This Section 7.01(b)
shall be in lieu of Section 315(a) of the TIA and such Section 315(a) is hereby
expressly excluded from this Indenture, as permitted by the TIA.

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

     (i) this Section 7.01(c) does not limit the effect of Sections 7.01(b) and
7.01(g);

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

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

                                       40

<PAGE>

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

     (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to this Section 7.01.

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

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

     (g) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

     Section 7.02 Rights of Trustee.

     Subject to the provisions of Section 7.01:

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

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

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

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

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

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

                                       41

<PAGE>

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

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

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

     (i) Except with respect to Section 4.01, the Trustee shall have no duty to
inquire as to the performance of the Company with respect to the covenants
contained in Article 4. In addition, the Trustee shall not be deemed to have
knowledge of an Event of Default except (i) any Default or Event of Default
occurring pursuant to Sections 6.01(a), 6.01(c), 6.01(d) or 6.01(e) or (ii) any
Default or Event of Default of which the Trustee shall have received written
notification or obtained actual knowledge;

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

     (k) the Trustee may request that the Company deliver an Officer's
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 Officer's Certificate may be signed by any person authorized to sign an
Officer's Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded;

     (l) the permissive rights of the Trustee to take certain actions under this
Indenture shall not be construed as a duty unless so specified herein;

     (m) delivery of reports, information and documents to the Trustee under
Section 4.02 is for informational purposes only and the Trustee's receipt of the
foregoing shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including compliance
with any of their covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officer's Certificates);

     (n) 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, 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; and

     (o) the Trustee shall not be responsible for any costs, expenses, damages
or other liabilities arising (directly or indirectly) as a result of (i) any
filing of a claim or proof of debt by holders of Senior Debt (or their
Representative) or (ii) any right of holders of Senior Debt (or their
Representative) to file any such claim or proof of debt, in any such case in
accordance with the second paragraph of Section 11.04.

     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 Section 7.10 and Section 7.11.

     Section 7.04 Trustee's Disclaimer.

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

     Section 7.05 Notice of Defaults.

     If a Default or Event of Default occurs and if it is known to the Trustee,
the Trustee shall give to each Securityholder notice of the Default or Event of
Default (and, to the extent applicable, notice if any payment is due with
respect to Section 6.03) within 90 days after it occurs or, if later, within 15
days after it is known to the Trustee, unless such Default or Event of Default
shall have been cured or waived before the giving of such notice.
Notwithstanding the preceding sentence, except in the case of a Default or Event
of Default described in clauses (d) and (e) of Section 6.01, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interest of the
Securityholders. The preceding sentence shall be in lieu of the proviso to
Section 315(b) of the TIA and such proviso is hereby expressly excluded from
this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have
knowledge of a Default or Event of Default unless a Responsible Officer of the
Trustee has received written notice of such Default or Event of Default, which
notice specifically references this Indenture and the Securities.

     Section 7.06 Reports by Trustee to Holders.

     Within 60 days after each December 31 beginning with December 31, 2007, the
Trustee shall mail to each Securityholder a brief report dated as of such
December 31 that complies with TIA Section 313(a), if required by such Section
313(a). The Trustee also shall comply with TIA Section 313(b). Any reports
required by this Section 7.06 shall be transmitted by mail to Securityholders
pursuant to TIA Section 313(c).

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

     Section 7.07 Compensation and Indemnity.

     The Company agrees:

     (a) to pay to the Trustee from time to time such compensation as the
Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which

                                       43

<PAGE>

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

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

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

     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, except that held in trust to pay the principal
amount of, or the Redemption Price, Repurchase Price, Fundamental Change
Repurchase Price, Interest or Additional Interest, if any, as the case may be,
on particular Securities.

     The Company's payment, reimbursement and indemnity obligations pursuant to
this Section 7.07 shall survive the satisfaction and discharge of this
Indenture, the resignation or removal of the Trustee and the termination of this
Indenture for any reason. In addition to and without prejudice to its rights
hereunder, when the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 6.01(i) or Section 6.01(j), the
expenses, including the reasonable charges and expenses of its counsel and the
compensation for services payable pursuant to Section 7.07(a), are intended to
constitute expenses of administration under any applicable federal or state
bankruptcy, insolvency or similar laws.

     For the purposes of this Section 7.07, the "Trustee" shall include any
predecessor Trustee; provided, however, that except as may be otherwise agreed
among the parties, the negligence, willful misconduct or bad faith of any
Trustee hereunder shall not affect the rights of any other Trustee hereunder.

     Section 7.08 Replacement of Trustee.

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

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

     (ii) the Trustee is adjudged bankrupt or insolvent;

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

     (iv) the Trustee otherwise becomes incapable of acting.

                                       44
<PAGE>

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

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

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

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

     So long as no Default or Event of Default shall have occurred and be
continuing, if the Company shall have delivered to the Trustee (i) a Board
Resolution appointing a successor Trustee, effective as of a date at least 30
days after delivery of such Resolution to the Trustee, and (ii) an instrument of
acceptance of such appointment, effective as of such date, by such successor
Trustee in accordance with this Indenture, the Trustee shall be deemed to have
resigned as contemplated in this Section 7.08, the successor Trustee shall be
deemed to have been accepted as contemplated in this Indenture, all as of such
date, and all other provisions of this Indenture shall be applicable to such
resignation, appointment and acceptance.

     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 Person,
the resulting, surviving or transferee Person without any further act shall be
the successor Trustee, subject to Sections 7.10 and 7.11.

     Section 7.10 Eligibility; Disqualification.

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

     Section 7.11 Preferential Collection of Claims Against Company.

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

Securities (other than Securities replaced or repaid pursuant to Section 2.07)
for cancellation or (ii) all outstanding Securities have become due and payable
and the Company deposits with the Trustee cash sufficient to pay all amounts due
and owing on all outstanding Securities (other than Securities replaced pursuant

applicable abandoned property law. After return to the Company, Holders entitled
to the money or securities must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another person
and the Trustee and the Paying Agent shall have no further liability to the
Securityholders with respect to such money or securities for that period
commencing after the return thereof.

     The Trustee shall hold in trust all money and other consideration deposited

held in trust is subject to the Trustee's rights under Section 7.07.

increase);

     (j) comply with the requirements of the SEC in order to effect or maintain

                                       47

<PAGE>

case with the written consent of the Holders of at least a majority of the
principal amount of the Securities at the time outstanding.

     Without the written consent or the affirmative vote of each Holder of

     (a) reduce the principal amount of or change the maturity of any Security,
or the payment date of any installment of Interest or Additional Interest

     (i) modify any of the provisions of this Section 9.02, or reduce the
percentage of the aggregate principal amount of outstanding Securities required
to amend, modify or supplement the Indenture or the Securities or waive an Event
of Default, except to provide that certain other provisions of this Indenture
cannot be modified or waived without the consent of the Holder of each
outstanding Security affected thereby; or

     (j) modify any of the provisions of this Indenture which relate to
subordination under Article 11 if such modification would adversely affect the
rights of Holders of Securities.

     It shall not be necessary for the consent of the Holders under this Section
9.02 to approve the particular form of any proposed amendment, but it shall be

     Section 9.03 Compliance With Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article 9 shall
comply with the TIA as then in effect.

     Section 9.04 Revocation and Effect of Consents, Waivers and Actions.

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

     Section 9.05 Notice of Amendments, Notation on or Exchange of Securities.

     Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article 9 may, and shall if required by
the Company, bear a notation in form approved by the Company 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 receive, and (subject to the provisions of Section
7.01) shall be fully protected in relying upon, an Officer's 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 9, 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.

                                   CONVERSIONS

     Section 10.01 Conversion Privilege.

     (a) Subject to and upon compliance with the provisions of this Article 10,
a Holder of a Security shall have the right, at such Holder's option, to convert
all or any portion (if the portion to be converted is $1,000 principal amount or
an integral multiple thereof) of such Security prior to the close of business on
the Business Day immediately preceding Stated Maturity into cash, shares of
Common Stock,

                                       49

<PAGE>

or a combination of cash and shares of Common Stock, as determined at the
Company's discretion, at the Conversion Rate (the "Conversion Obligation") in
effect on the date of conversion only as follows:

     (i) during any fiscal quarter of the Company (a "Fiscal Quarter")
commencing after the fiscal quarter ending March 31, 2007 (and only during such
Fiscal Quarter), if the Last Reported Sale Price of the Common Stock for at
least 20 Trading Days during the period of 30 consecutive Trading Days ending on
the last Trading Day of the immediately preceding Fiscal Quarter is more than
130% of the Conversion Price in effect on such last Trading Day;

     (ii) during the five Business Day period immediately following any five
consecutive Trading Day period (the "Measurement Period") in which the Trading
Price per $1,000 original principal amount of the Securities for each day of
such Measurement Period was less than 98% of the product of the Last Reported
Sale Price of the Common Stock and the Conversion Rate on each such date. The
Conversion Agent will, on the Company's behalf, determine if the Securities are
convertible as a result of the Trading Price of the Securities and notify the
Company and the Trustee; provided that the Conversion Agent shall have no
obligation to determine the Trading Price of the Securities unless the Company
has requested such determination in writing and the Company shall have no
obligation to make such request unless requested to do so by a Holder of the
Securities. Upon making any such request, any such requesting Holder shall
provide reasonable evidence that (A) such requesting Holder is a Holder of the
Securities as of the date of such notice, and (B) the Trading Price per $1,000
principal amount of Securities would be less than 98% of the product of the Last
Reported Sale Price of the Common Stock and the Conversion Rate. At such time,
the Company shall instruct the Conversion Agent 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 original principal amount of the
Securities is greater than or equal to 98% of the product of the Last Reported
Sale Price of the Common Stock and the Conversion Rate;

     (iii) at any time prior to the close of business on the second Business Day
immediately preceding the Redemption Date, if the Company has called the
Securities for redemption pursuant to Article 3 hereof, even if the Securities
are not otherwise convertible at that time;

     (iv) any time on or after November 1, 2026 and prior to the close of
business on the Stated Maturity;

     (v) as provided in clause (b) of this Section 10.01.

     The Company or, at its option, the Conversion Agent on behalf of the
Company, shall determine on a daily basis during the time periods specified in
Section 10.01(a)(i) or, following a request by a Holder of Securities in
accordance with the procedures specified in Section 10.01(a)(ii), whether the
Securities shall be convertible as a result of the occurrence of an event
specified in such Sections and, if the Securities shall be so convertible, the
Company or the Conversion Agent, as applicable, shall promptly deliver to the
Trustee and Conversion Agent or the Company, as applicable written notice
thereof. Whenever the Securities shall become convertible pursuant to this
Section 10.01 (as determined in accordance with this Section 10.01), the Company
or, at the Company's request, the Trustee in the name and at the expense of the
Company, shall promptly notify the Holders (with a copy to the Trustee and
Conversion Agent) of the event triggering such convertibility in the manner
provided in Section 13.02, and the Company shall also promptly disseminate a
press release through Dow Jones & Company, Inc. or Bloomberg Business News and
publish such information on the Company's Website or through another public
medium the Company may use at that time. Any notice so given shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice.

     (b) In the event that:

                                       50

<PAGE>

          (1) (A) the Company distributes to all or substantially all holders of
     Common Stock rights or warrants entitling them to purchase, for a period
     expiring within 60 days after the date of such distribution, Common Stock
     at less than the Last Reported Sale Price of the Common Stock on the
     Trading Day immediately preceding the announcement date for such
     distribution; or (B) the Company distributes to all or substantially all
     holders of Common Stock assets (including cash), debt securities or rights
     or warrants to purchase the Company's securities, which distribution has a
     per share value as determined by the Board of Directors exceeding 10% of
     the Last Reported Sale Price of the Common Stock on the Trading Day
     immediately preceding the announcement date of such distribution, then, in
     either case, the Securities may be surrendered for conversion at any time
     on and after the date that the Company gives notice to the Trustee and the
     Holders of such distribution, which shall be not less than 20 Business Days
     prior to the Ex-Dividend Date for such distribution, until the earlier of
     the close of business on the Business Day immediately preceding the
     Ex-Dividend Date or the date the Company announces that such distribution
     shall not take place, even if the Securities are not otherwise convertible
     at such time; provided that no Holder of a Security shall have the right to
     convert if the Holder may otherwise participate in such distribution
     without conversion; or

          (2) a Fundamental Change occurs, then the Securities may be
     surrendered for conversion at any time from and after the date which is 15
     days prior to the anticipated effective date of such transaction until and
     including the date which is 15 days after the actual effective date of such
     transaction (or, if such transaction also constitutes a Change of Control
     pursuant to which Holders have a right to require the Company to repurchase
     the Securities pursuant to Section 3.08, until the applicable Fundamental
     Change Repurchase Date). The Company shall notify the Trustee and Holders
     at the time the Company publicly announces the Change of Control
     transaction giving rise to the above conversion right (but in no event less
     than 15 days prior to the anticipated effective date of such transaction).
     If the Company engages in any reclassification of the Common Stock (other
     than a subdivision or combination of its outstanding Common Stock, or a
     change in par value, or from par value to no par value, or from no par
     value to par value) or is party to a consolidation, merger, binding share
     exchange or transfer of all or substantially all of its assets pursuant to
     which Holders of Common Stock would be entitled to receive cash, securities
     or other property, then at the effective time of such transaction, to the
     extent that it constitutes a Change of Control as described in this
     paragraph above as giving rise to a conversion right, the Conversion
     Obligation and the Conversion Settlement Distribution shall be based on the
     applicable Conversion Rate and the kind and amount of cash, securities or
     other property that a holder of one share of the Common Stock would have
     received in such transaction as determined pursuant to Section 10.05(b)
     (such property, collectively, the "Exchange Property"). In addition, if a
     Holder converts Securities following the effective time of any such
     transaction, any amounts of the Conversion Settlement Distribution to be
     settled in shares of Common Stock shall be paid in such Exchange Property
     rather than shares of Common Stock. If the transaction also constitutes a
     Fundamental Change, (A) a Holder can require the Company to repurchase all
     or a portion of its Securities pursuant to Section 3.08 or, (B) if such
     Holder elects, instead, to convert all or a portion of its Securities, such
     Holder shall receive Additional Shares upon conversion pursuant to Section
     10.01(c), in each case, subject to the terms and conditions set forth in
     each such Section.

     (c) If and only to the extent a Holder timely elects to convert Securities
during the period specified in Section 10.01(b)(2) above on or prior to February
1, 2017, and 10% or more of the consideration for the Common Stock in such
Change of Control transaction consists of consideration other than common stock
traded or scheduled to be traded immediately following such transaction on a
U.S. national securities exchange or The New York Stock Exchange, the Conversion
Rate shall be increased by an additional number of shares of Common Stock (the
"Additional Shares") as described

                                       51

<PAGE>

below; provided that if the Stock Price paid in connection with such transaction
is greater than $100.00 or less than $20.24 (subject in each case to adjustment
as described below), no Additional Shares shall be added to the Conversion Rate.
Notwithstanding this Section 10.01(c), if the Company elects to adjust the
Conversion Rate pursuant to Section 10.01(d), the provisions of Section 10.01(d)
shall apply in lieu of the provisions of this Section 10.01(c). The Company
shall notify the Trustee and Holders, at least 15 days prior to the anticipated
effective date of such transaction causing any increase of the Conversion Rate
pursuant to this Section 10.01(c), whether the Company elects to increase the
Conversion Rate as described above or to adjust the Conversion Rate pursuant to
Section 10.01(d).

     The number of Additional Shares to be added to the Conversion Rate as
described in the immediately preceding paragraph shall be determined by
reference to the table attached as Schedule I hereto, based on the effective
date of such Change of Control transaction and the Stock Price paid in
connection with such transaction; provided that if the Stock Price is between
two Stock Price amounts in the table or such effective date is between two
effective dates in the table, the number of Additional Shares shall be
determined by a straight-line interpolation between the number of Additional
Shares set forth for the higher and lower Stock Price amounts and the two dates,
as applicable, based on a 365-day year. The "effective date" with respect to a
Change of Control transaction means the date that a Change of Control becomes
effective.

     With respect to any Securities tendered for conversion to which Additional
Shares apply, any shares of Common Stock to be delivered upon conversion of such
Securities pursuant to Section 10.02 shall be delivered to Holders who elect to
convert their Securities on the later of (1) the fifth Business Day following
the effective date and (2) the third Business Day following the final day of the
Cash Settlement Averaging Period.

     The Stock Prices set forth in the first row of the table in Schedule I
hereto shall be adjusted as of any date on which the Conversion Rate of the
Securities is adjusted pursuant to Section 10.04. The adjusted Stock Prices
shall equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Rate
immediately prior to the adjustment giving rise to the Stock Price adjustment
and the denominator of which is the Conversion Rate as so adjusted. The number
of Additional Shares shall be adjusted in the same manner as the Conversion Rate
as set forth in Section 10.04.

     Notwithstanding the foregoing, in no event shall the total number of shares
of Common Stock issuable upon conversion of the Securities exceed 49.4071 per
$1,000 principal amount of Securities, subject to adjustments in the same manner
as the Conversion Rate as set forth in Section 10.04.

     (d) Notwithstanding the provisions of Section 10.01(c), in the case of a
Change of Control that would lead to the issuance of Additional Shares as set
forth in clause (c) above that is also a Public Acquirer Change of Control, the
Company may, at its option and in lieu of increasing the Conversion Rate by
Additional Shares as described in Section 10.01(c), elect to adjust the
Conversion Rate and the related Conversion Obligation such that from and after
the effective date of such Public Acquirer Change of Control, Holders of
Securities shall be entitled to convert their Securities (subject to the
satisfaction of the conditions to conversion set forth in Sections 10.01(a) and
10.03) into Public Acquirer Common Stock.

     The Conversion Rate following the effective date of such transaction will
be a number of shares of Public Acquirer Common Stock equal to the product
obtained by multiplying the Conversion Rate in effect immediately before the
Public Acquirer Change of Control and the average of the quotients obtained by
dividing:

                                       52

<PAGE>

     (i) the Acquisition Value of the Company's Common Stock by

     (ii) the Last Reported Sale Price of the Public Acquirer Common Stock for
each such Trading Day in the 10 consecutive Trading Day period ending on the
Trading Day immediately preceding the effective date of such Public Acquirer
Change of Control (the "Valuation Period").

     The "Acquisition Value" of the Common Stock means, for each Trading Day in
the Valuation Period, the value of the consideration paid per share of Common
Stock in connection with such Public Acquirer Change of Control, as follows:

     (i) For any cash, 100% of the face amount of such cash;

     (ii) for any Public Acquirer Common Stock, 100% of the Last Reported Sale
Price of such Public Acquirer Common Stock on such trading day; and

     (iii) for any other securities, assets or property, 102% of the fair market
value of such security, asset or property on such Trading Day, as determined by
three independent nationally recognized investment banks selected by the Company
for this purpose (or if prices are not available from three such firms, from two
such firms or, if prices are not available from two such firms, from one such
firm).

     "Public Acquirer Change of Control" means an event constituting a corporate
transaction that would otherwise obligate the Company to increase the Conversion
Rate as described in Section 10.01(c) and the acquirer, the Person formed by or
surviving the merger or consolidation or any entity that is direct or indirect
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act) of more
than 50% of such Person's or acquirer's Voting Stock has a class of common stock
traded on a national securities exchange or quoted on The New York Stock
Exchange or which shall be so traded or quoted when issued or exchanged in
connection with such Change of Control (the "Public Acquirer Common Stock");
provided, that if there is more than one of such entity, the relevant entity
shall be such entity with the most direct beneficial ownership to such
acquirer's or Person's capital stock.

     Upon a Public Acquirer Change of Control, if the Company so elects, Holders
may convert their Securities (subject to the satisfaction of the conditions to
conversion set forth in Section 10.01(a)) at the adjusted Conversion Rate
described above but shall not be entitled to the increased Conversion Rate
described in Section 10.01(c). The Company shall notify the Trustee and Holders
of its election in its written notice to Holders pursuant to Section 10.01(b)(2)
above. Holders may convert their Securities upon a Public Acquirer Change of
Control during the period specified in Section 10.01(b)(2). In addition, Holders
can also, subject to certain conditions, require the Company to repurchase all
or a portion of their Securities as described in Section 3.08.

     After any adjustment of the Conversion Rate in connection with a Public
Acquirer Change of Control, the Conversion Rate shall be subject to further
similar adjustments in the event that any of the events described in Section
10.04 occur thereafter.

     The Company may only make such election if such public acquirer is a
corporation organized under the laws of the United States, any State thereof or
the District Columbia and if the Company and such public acquirer executes a
supplemental indenture whereby the public acquirer agrees to comply with the
obligations of the Company under the Securities and the Indenture applicable to
such public acquirer or any securities thereof that may be issuable upon
conversion of the Securities.

     Section 10.02 Conversion Procedure; Conversion Rate; Fractional Shares.

     Subject to Section 10.01 and the Company's rights under Section 10.03, each
Security shall be convertible at the office of the Conversion Agent into a
combination of cash and fully paid and nonassessable shares (calculated to the
nearest 1/100th of a share) of Common Stock, if any, at a rate (the "Conversion
Rate") equal to, initially, 40.3323 shares of Common Stock for each $1,000
principal amount of Securities. The Conversion Rate shall be adjusted in certain
instances as provided in Section 10.04 hereof, but shall not be adjusted for any
accrued and unpaid Interest or Additional Interest, if any, unless such
Conversion Date occurs between an Interest Record Date and the Interest Payment
Date to which that Interest Record Date relates. Upon conversion, no payment
shall be made by the Company with respect to any accrued and unpaid Interest,
including Additional Interest, if any. Instead, such amount shall be deemed paid
by the applicable Conversion Settlement Distribution delivered upon conversion
of any Security. In addition, no payment or adjustment shall be made in respect
of dividends on the Common Stock with a record date prior to the Conversion
Date. The Company shall not issue any fraction of a share of Common Stock in
connection with any conversion of Securities, but instead shall, subject to
Section 10.03 hereof, make a cash payment (calculated to the nearest cent) equal
to such fraction multiplied by the Last Reported Sale Price of the Common Stock
on the Trading Day prior to the Conversion Date.

     (a) Before any Holder of a Security shall be entitled to convert the same
into a combination of cash and Common Stock, if any, such Holder shall (1) in
the case of Global Securities, comply with the procedures of the Depositary in
effect at that time for converting a beneficial interest in a Global Security,
and in the case of Certificated Securities, surrender such Securities, duly
endorsed to the Company or in blank, at the office of the Conversion Agent, and
(2) give written notice to the Conversion Agent in the form on the reverse of
such Certificated Security (the "Conversion Notice") at said office or place
that such Holder elects to convert the same and shall state in writing therein
the principal amount of Securities to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for
Common Stock included in the Conversion Settlement Distribution, if any, to be
registered.

     Before any such conversion, a Holder also shall pay all taxes or duties, if
any, as provided in Section 10.06 and any amount payable pursuant to Section
10.02(f).

     If more than one Security shall be surrendered for conversion at one time
by the same Holder, the number of full shares of Common Stock, if any, that
shall be deliverable upon conversion as part of the Conversion Settlement
Distribution shall be computed on the basis of the aggregate principal amount of
the Securities (or specified portions thereof to the extent permitted thereby)
so surrendered.

     (b) A Security shall be deemed to have been converted as of the close of
business on the date (the "Conversion Date") that the Holder has complied with
Section 10.02(a).

     (c) The Company shall, on the Conversion Settlement Date, (i) pay the cash
component (including cash in lieu of any fraction of a share to which such
Holder would otherwise be entitled) of the Conversion Obligation determined
pursuant to Section 10.03 to the Holder of a Security surrendered for
conversion, or such Holder's nominee or nominees or, and (ii) issue, or cause to
be issued, and deliver to the Conversion Agent or to such Holder, or such
Holder's nominee or nominees, certificates for the number of full shares of
Common Stock, if any, or make a book-entry transfer through DTC with respect to
uncertficated Shares, if applicable, to which such Holder shall be entitled as
part of such Conversion Obligation. The Company shall not be required to deliver
certificates for shares of Common Stock while the stock transfer books for such
stock or the security register are duly closed for any purpose, but certificates
for shares of Common Stock shall be issued and delivered as soon as practicable
after the

                                       54

<PAGE>

opening of such books or security register, and the Person or Persons entitled
to receive the Common Stock as part of the applicable Conversion Settlement
Distribution upon such conversion shall be treated for all purposes as the
record holder or holders of such Common Stock, as of the close of business on
the applicable Conversion Settlement Date.

     (d) In case any Security shall be surrendered for partial conversion, the
Company shall execute and the Trustee shall authenticate and deliver to or upon
the written order of the Holder of the Security so surrendered, without charge
to such Holder (subject to the provisions of Section 10.06 hereof), a new
Security or Securities in authorized denominations in an aggregate principal
amount equal to the unconverted portion of the surrendered Securities.

     (e) By delivering the combination of cash and shares of Common Stock, if
any, together with a cash payment in lieu of any fractional shares to the
Conversion Agent or to the Holder or such Holder's nominee or nominees, the
Company shall have satisfied in full its Conversion Obligation with respect to
such Security, and upon such delivery, accrued and unpaid Interest, if any, and
Additional Interest, if any, with respect to such Security shall be deemed to be
paid in full rather than canceled, extinguished or forfeited, and such amounts
shall no longer accrue.

     (f) If a Securityholder delivers a Conversion Notice after the Interest
Record Date for a payment of Interest (including Additional Interest, if any)
but prior to the corresponding Interest Payment Date, such Securityholder must
pay to the Company, at the time such Securityholder surrenders Securities for
conversion, an amount equal to the Interest (including Additional Interest, if
any), that has accrued and shall be paid on the related Interest Payment Date.
The preceding sentence shall not apply if (1) the Company has specified a
Redemption Date that is after an Interest Record Date but on or prior to the
corresponding Interest Payment Date, (2) the Company has specified a Fundamental
Change Repurchase Date during such period referred to in clause (1) of this
paragraph or (3) to the extent of overdue Interest (including Additional
Interest, if any), if any overdue Interest exists at the time of conversion with
respect to the Securities converted.

     Section 10.03 Payment Upon Conversion.

     (a) In the event that the Company receives a Conversion Notice on or prior
to the day that is 20 days prior to either Stated Maturity or, with respect to
Securities being redeemed, the applicable Redemption Date (the "Final Notice
Date"), the following procedures will apply:

     If the Company chooses to satisfy all or any portion of its Conversion
Obligation in cash, the Company will notify such Holder through the Trustee of
the dollar amount to be satisfied in cash (which must be expressed either as
100% of the Conversion Obligation or as a fixed dollar amount) at any time on or
before the date that is two Business Days following the Company's receipt of the
Conversion Notice as specified in Section 10.02 (such period, the "Cash
Settlement Notice Period"). If the Company timely elects to pay cash for any
portion of the Common Stock otherwise issuable to such Holder, the Conversion
Notice may be retracted at any time during the two Business Day period beginning
on the day after the final day of the Cash Settlement Notice Period (the
"Conversion Retraction Period"); no such retraction can be made (and a
Conversion Notice shall be irrevocable) if the Company does not elect to deliver
cash in lieu of shares of Common Stock (other than cash in lieu of fractional
shares). If the Conversion Notice is not retracted within the Conversion
Retraction Period, then settlement of the Conversion Obligation (in cash and/or
shares of Common Stock) (the "Conversion Settlement Distribution") (other than
with respect to any Additional Shares, for which settlement shall occur in the
time periods specified in Section 10.01(c)) will occur on the third Business Day
following the final day of the 20 Trading Day period beginning on the Trading
Day after the final day of the Conversion Retraction

                                       55

<PAGE>

Period (the "Cash Settlement Averaging Period"). The Conversion Settlement
Distribution will be computed as follows:

     (i) If the Company elects to satisfy the entire Conversion Obligation in
shares of Common Stock, the Company shall deliver to Holders surrendering
Securities for conversion a number of shares of Common Stock equal to (1) the
aggregate principal amount of Securities to be converted divided by 1,000,
multiplied by (2) the sum of the applicable Conversion Rate and the applicable
number of Additional Shares issuable upon conversion of $1,000 principal amount
of Securities, if any. In addition, the Company will pay cash for all fractional
shares of Common Stock as set forth in Section 10.02(c).

     (ii) If the Company elects to satisfy the entire Conversion Obligation in
cash, the Company will deliver to Holders surrendering Securities for
conversion, for each $1,000 principal amount of Securities, cash in an amount
equal to the product of:

          (1) a number equal to (x) the aggregate principal amount of Securities
to be converted divided by 1,000 multiplied by (y) the number of shares of
Common Stock calculated pursuant to subclause (2) of clause (i) of this Section
10.03(a), and

          (2) the average of the Closing Prices of the Common Stock during each
Trading Day during the Cash Settlement Averaging Period.

     (iii) If the Company elects to satisfy a fixed portion (other than 100%) of
the Conversion Obligation in cash, the Company will deliver to Holders
surrendering Securities for conversion, for each $1,000 principal amount of
Securities, such cash amount (the "Cash Amount") and a number of shares of
Common Stock equal to the excess, if any, of the number of shares of Common
Stock calculated pursuant to subclause (2) of clause (i) of this Section
10.03(a) over the number of shares of Common Stock equal to the sum, for each
day of the Cash Settlement Averaging Period, of (x) 5% of the Cash Amount (other
than cash for fractional shares of Common Stock), divided by (y) the Closing
Price of the Common Stock on such day. In addition, the Company will pay cash
for all fractional shares of Common Stock as set forth in Section 10.02(c).

     (b) (i) In the event that the Company receives a Conversion Notice after
the Final Notice Date, if the Company chooses to satisfy all or any portion of
the Conversion Obligation in cash, the Company shall send, on or prior to the
Final Notice Date, a single notice to the Trustee of the dollar amount to be
satisfied in cash (which must be expressed either as 100% of the Conversion
Obligation or as a fixed dollar amount). If the Company delivers a single notice
to the Trustee, the Company will not send individual notices of its election to
satisfy all or any portion of the Conversion Obligation in cash. The Conversion
Settlement Distribution will be computed in the same manner as set forth under
Section 10.03(a) above except that the "Cash Settlement Averaging Period" shall
be the 20 Trading Day period beginning on the Trading Day after the receipt of
the Conversion Notice (or, in the event the Company receives the Conversion
Notice on the Business Day prior to the Stated Maturity, the 20 Trading Day
period beginning on the Trading Day after the Stated Maturity). Settlement of
the Conversion Obligation pursuant to this Section 10.03(b)(i) (in cash and/or
shares of Common Stock) (other than with respect to any Additional Shares, for
which settlement shall occur in the time periods specified in Section 10.01(c))
will occur on the third Business Day following the final day of such Cash
Settlement Averaging Period.

     (ii) If a Holder elects to convert Securities pursuant to Section
10.01(a)(5) and such Holder, in connection with such conversion, would be
entitled to receive Additional Shares, the Company will not send individual
notices of its election to satisfy all or any portion of the Conversion
Obligation in cash. Instead, if the Company chooses to satisfy all or any
portion of the Conversion Obligation in cash, unless the Company has previously
sent a notice pursuant to Section 10.03(c), the Company will send a single

                                       56

<PAGE>

notice to the Trustee of the dollar amount to be satisfied in cash (which must
be expressed either as 100% of the Conversion Obligation or as a fixed dollar
amount) in connection with the announcement of the relevant corporate
transaction. The Conversion Settlement Distribution will be computed in the same
manner as set forth in Section 10.03(a) except that (1) the Cash Settlement
Averaging Period shall be the 20 Trading Day period beginning on the Trading Day
after the receipt of the Conversion Notice (or, in the event the Company
receives the Conversion Notice on the Business Day prior to the Stated Maturity,
the 20 Trading Day period beginning on the Trading Day after the Stated
Maturity), and (2) if the Securities become convertible into Exchange Property,
the Closing Price of the Common Stock shall be deemed to equal the sum of (A)
100% of the value of any Exchange Property consisting of cash received per share
of Common Stock, (B) the Closing Price of any Exchange Property received per
share of Common Stock consisting of securities that are traded on a U.S.
national securities exchange or approved for quotation on The New York Stock
Exchange and (3) the Fair Market Value of any other Exchange Property received
per share, as determined by two independent nationally recognized investment
banks selected by the Trustee for this purpose. Settlement (in cash and/or
shares) will occur on the third Business Day following the final day of such
Cash Settlement Averaging Period.

     (c) Notwithstanding anything to the contrary in this Indenture, at any time
prior to Stated Maturity, the Company may irrevocably elect, with respect to any
Securities which may be converted after the date of such election, in its sole
discretion without the consent of the Holders of the Securities, by notice to
the Trustee and the Holders of the Securities,

     (i) to satisfy in cash the lesser of (1) (A) the Conversion Rate,
multiplied by (B) the average Closing Price of the Common Stock during the Cash
Settlement Averaging Period and (2) 100% of the principal amount of any such
Security, with any remaining amount to be satisfied in shares of Common Stock,
or

     (ii) to satisfy all of the Conversion Obligation in shares of Common Stock.

     Any Conversion Notice delivered following the date the Company makes either
such election shall not be retractable, and the Conversion Settlement
Distribution shall be computed and settlement dates shall be determined in the
same manner as set forth in Section 10.03(a), except that the Cash Settlement
Averaging Period shall be the 20 Trading Day period beginning on the Trading Day
after receipt of the Conversion Notice. In the case of any Holders who elect to
convert any Securities pursuant to the provisions set forth in Section
10.01(a)(5) following the date the Company makes either election set forth in
this Section 10.03(c), and such Holder, in connection with such conversion,
would be entitled to receive Additional Shares, the Conversion Settlement
Distribution will be computed and the settlement dates will be determined in the
same manner as set forth in Section 10.03(b)(ii).

     Section 10.04 Adjustment of Conversion Rate.

     The Conversion Rate shall be adjusted, without duplication, from time to
time by the Company in accordance with this Section 10.04:

     (a) In case the Company shall hereafter pay a dividend or make a
distribution to all or substantially all holders of the outstanding Common Stock
in shares of Common Stock, the Conversion Rate shall be increased so that the
same shall equal the rate determined by multiplying the Conversion Rate in
effect at the opening of business on the date following the date fixed for the
determination of shareholders entitled to receive such dividend or other
distribution by a fraction,

                                       57

<PAGE>

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

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If any dividend or
distribution of the type described in this Section 10.04 is declared but not so
paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate
that would then be in effect if such dividend or distribution had not been
declared.

     (b) In case the Company shall issue rights, warrants or options (other than
pursuant to any dividend reinvestment or share repurchase plans) to all or
substantially all holders of its outstanding shares of Common Stock entitling
them (for a period expiring within 60 days after the date of such distribution)
to subscribe for or purchase shares of Common Stock at a price per share less
than the Current Market Price on the date fixed for determination of
shareholders entitled to receive such rights, warrants or options, the
Conversion Rate shall be adjusted so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect immediately prior to the
date fixed for determination of shareholders entitled to receive such rights,
warrants or options by a fraction,

     (i) the numerator of which shall be the sum of (A) the number of shares of
Common Stock outstanding on the date fixed for determination of shareholders
entitled to receive such rights or warrants plus (B) the total number of
additional shares of Common Stock offered for subscription or purchase, and

     (ii) the denominator of which is the sum of (A) the number of shares of
Common Stock outstanding on the date fixed for determination of shareholders
entitled to receive such rights or warrants plus (B) the total number of
additional shares of Common Stock that the aggregate offering price of the total
number of shares of Common Stock offered for subscription or purchase would
purchase at the Current Market Price of the Common Stock on such date.

     Such adjustment shall be successively made whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of
business on the day following the date fixed for determination of shareholders
entitled to receive such rights or warrants. To the extent that shares of Common
Stock are not delivered after the expiration of such rights or warrants, the
Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect had the adjustments made upon the issuance of such rights or warrants
been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. In the event that such rights or warrants are not so
exercised, the Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such date fixed for the determination of
shareholders entitled to receive such rights or warrants had not been fixed. In
determining whether any rights, options or warrants entitle the holders to
subscribe for or purchase shares of Common Stock at less than such Current
Market Price, and in determining the aggregate offering price of such shares of
Common Stock, there shall be taken into account any consideration received by
the Company for such rights or warrants and any amount payable on exercise or
conversion thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors.

     (c) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of

                                       58

<PAGE>

shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such combination becomes effective shall
be proportionately reduced, such increase or reduction, as the case may be, to
become effective immediately after the opening of business on the day following
the day upon which such subdivision or combination becomes effective.

     (d) In case the Company shall, by dividend or otherwise, distribute to all
or substantially all holders of its Common Stock shares of any class of Capital
Stock of the Company or evidences of its indebtedness or other assets (including
securities, but excluding any rights, options or warrants referred to in Section
10.04(b) and excluding any dividend or distribution (x) paid exclusively in cash
or (y) referred to in Section 10.04(a)) (any of the foregoing hereinafter in
this Section 10.04(d) called the "Distributed Assets"), then, in each such case,
the Conversion Rate shall be increased so that the same shall be equal to the
rate determined by multiplying the Conversion Rate in effect on the Ex-Dividend
Date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the Current Market Price per share of
the Common Stock on such Ex-Dividend Date; and

     (ii) the denominator of which shall be the Current Market Price per share
of the Common Stock less the Fair Market Value (as determined by the Board of
Directors and described in a resolution of the Board of Directors) on the
Ex-Dividend Date of the portion of the Distributed Assets so distributed in
respect of one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business
on the day following such Ex-Dividend Date; provided, however, that in the event
(1) the then Fair Market Value (as so determined) of the portion of the
Distributed Assets so distributed applicable to one share of Common Stock is
equal to or greater than the Current Market Price of the Common Stock on such
Ex-Dividend Date or (2) the Current Market Price of Common Stock on the
Ex-Dividend Date exceeds the then Fair Market Value (as so determined) of the
portion of the Distributed Assets so distributed applicable to one share of
Common Stock by less than $1.00, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder shall have the right to receive upon
conversion the amount of Distributed Assets such Holder would have received had
such Holder converted each Security on the Ex-Dividend Date for such
distribution. In the event that such dividend or distribution is not so paid or
made, the Conversion Rate shall be adjusted to be the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared. If the
Board of Directors determines the Fair Market Value of any distribution for
purposes of this Section 10.04(d) by reference to the actual or when issued
trading market for any securities, it must in doing so consider the prices in
such market over the same period used in computing the Current Market Price of
the Common Stock.

     Rights or warrants distributed by the Company to all holders of Common
Stock entitling the Holders thereof to subscribe for or purchase shares of the
Company's Capital Stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 10.04 (and no adjustment to the Conversion Rate under
this Section 10.04 shall be required) until the occurrence of the earliest
Trigger Event, whereupon such rights and warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 10.04. If any such right or warrant,
including any such existing rights or warrants distributed prior to the date of
this Indenture, are subject to events, upon the occurrence of which such rights
or warrants become exercisable to purchase different securities, evidences of
indebtedness or other assets, then the date of the occurrence of any and each
such event shall be deemed to be the date of distribution and record date with
respect to new rights or warrants

                                       59

<PAGE>

with such rights (and a termination or expiration of the existing rights or
warrants without exercise by any of the holders thereof). In addition, in the
event of any distribution (or deemed distribution) of rights or warrants, or any
Trigger Event or other event (of the type described in the preceding sentence)
with respect thereto that was counted for purposes of calculating a distribution
amount for which an adjustment to the Conversion Rate under this Section 10.04
was made, (1) in the case of any such rights or warrants that shall all have
been redeemed or repurchased without exercise by any holders thereof, the
Conversion Rate shall be readjusted upon such final redemption or repurchase to
give effect to such distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or repurchase
price received by a holder or holders of Common Stock with respect to such
rights or warrants (assuming such holder had retained such rights or warrants),
made to all holders of Common Stock as of the date of such redemption or
repurchase, and (2) in the case of such rights or warrants that shall have
expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights and warrants had not been
issued.

     No adjustment of the Conversion Rate shall be made pursuant to this Section
10.04(d) in respect of rights or warrants distributed or deemed distributed on
any Trigger Event to the extent that such rights or warrants are actually
distributed, or reserved by the Company for distribution to Holders of
Securities upon conversion by such Holders of Securities to Common Stock.

     For purposes of this Section 10.04(d) and Section 10.04(a) and (b), any
dividend or distribution to which this Section 10.04(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock (or both), shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, assets or shares of
capital stock other than such shares of Common Stock or rights or warrants (and
any Conversion Rate adjustment required by this Section 10.04(d) with respect to
such dividend or distribution shall then be made) immediately followed by (2) a
dividend or distribution of such shares of Common Stock or such rights or
warrants (and any further Conversion Rate adjustment required by Section
10.04(a) and (b) with respect to such dividend or distribution shall then be
made), except (A) the Ex-Dividend Date of such dividend or distribution shall be
substituted as "the date fixed for the determination of shareholders entitled to
receive such dividend or other distribution," "the date fixed for the
determination of shareholders entitled to receive such rights or warrants" and
"the date fixed for such determination" within the meaning of Section 10.04(a)
and (b), and (B) any shares of Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of Section 10.04(a).

     If any Distributed Assets requiring any adjustment pursuant to this Section
10.04(d) consists of the Capital Stock, or similar equity interests in, a
Subsidiary or other business unit of the Company which are or in connection with
such distribution will be listed or quoted for trading on a U.S. national or
regional securities exchange or The New York Stock Exchange, the Conversion Rate
in effect immediately before the close of business on the Ex-Dividend Date fixed
for determination of shareholders entitled to receive the distribution shall
instead be increased by multiplying the Conversion Rate then in effect by a
fraction, (A) the numerator of which is the sum of (1) the average of the Last
Reported Sale Prices of such distributed security for the 10 Trading Days
commencing on and including the fifth Trading Day after the Ex-Dividend Date on
The New York Stock Exchange or such other national or regional exchange or
market on which such securities are then listed or quoted plus (2) the average
of the Closing Prices of the Common Stock over the same Trading Day period and
(B) the denominator of which is such average of the Last Reported Sale Prices of
the Common Stock for the 10 Trading Days commencing on and including the fifth
Trading Day after the Ex-Dividend Date on The New York Stock Exchange or such
other national or regional exchange or market on which the securities are then
listed or quoted.

                                       60

<PAGE>

     (e) In case the Company shall, by dividend or otherwise, distribute to all
or substantially all holders of its Common Stock cash (an "Extraordinary Cash
Dividend") (excluding any quarterly cash dividend on the Company's Common Stock
to the extent that the aggregate cash dividend per share of Common Stock related
to any fiscal quarter does not exceed $0.0125 (which amount shall be
proportionally adjusted in the event of any occurrence described in Section
10.04(a) and Section 10.04(c) (the "Dividend Threshold Amount")), then, in such
case, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect immediately prior
to the close of business on the Ex-Dividend Date for such Extraordinary Cash
Dividend by a fraction,

     (i) the numerator of which shall be the Closing Price of the Common Stock
as of the Trading Day before such Ex-Dividend Date, and

     (ii) the denominator of which shall be such Closing Price of the Common
Stock as of the Trading Day before such Ex-Dividend Date minus the amount in
cash per share the Company distributes to holders in excess of the Dividend
Threshold Amount (and for which no adjustment has been made).

     If an adjustment is required to be made pursuant to this Section 10.04(e),
as a result of a distribution that is not a regular quarterly cash dividend, the
Dividend Threshold Amount will be deemed to be zero. The Dividend Threshold
Amount is subject to adjustment in a manner inversely proportional to
adjustments to the Conversion Rate, provided that no adjustment shall be made to
the Dividend Threshold Amount for any adjustment made to the Conversion Rate
pursuant to this Section 10.04(e).

     The adjustment shall become effective immediately after the close of
business on the Business Day immediately preceding the Ex-Dividend Date with
respect to the distribution.

     As used in this Section 10.04(e), "Ex-Dividend Date" means the first date
on which the shares of Common Stock trade on the applicable exchange or in the
applicable market, regular way, without the right to receive the issuance,
dividend or distribution in question.

     (f) In case a tender (other than an odd-lot offer) or exchange offer made
by the Company or any Subsidiary for all or any portion of the Common Stock
shall expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to shareholders of consideration per share of
Common Stock having a Fair Market Value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a resolution
of the Board of Directors) that as of the last time (the "Expiration Time")
tenders or exchanges may be made pursuant to such tender or exchange offer (as
it may be amended) exceeds the Last Reported Sale Price of the Common Stock on
the Trading Day next succeeding the Expiration Time, the Conversion Rate shall
be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect immediately prior to the Expiration Time by a
fraction,

     (i) the numerator of which shall be the sum of (x) the Fair Market Value
(determined as aforesaid) of the aggregate consideration payable to shareholders
based on the acceptance (up to any maximum specified in the terms of the tender
or exchange offer) of all shares validly tendered or exchanged and not withdrawn
as of the Expiration Time (the shares deemed so accepted up to any such maximum,
being referred to as the "Purchased Shares") and (y) the product of the number
of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the average of the Last Reported Sale Prices of the Common
Stock on the 10 Trading Days commencing on and including the first Trading Day
after the Expiration Time, and

     (ii) the denominator of which shall be the product of the number of shares
of Common Stock outstanding (including any Purchased Shares) at the Expiration
Time multiplied by the average of the

                                       61

<PAGE>

Last Reported Sale Prices of the Common Stock on the 10 Trading Days commencing
on and including the first Trading Day after the Expiration Time,

such adjustment to become effective immediately prior to the opening of business
on the day following the Expiration Time. In the event that the Company is
obligated to purchase shares pursuant to any such tender or exchange offer, but
the Company is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such
tender or exchange offer had not been made.

     (g) The Company may make such increases in the Conversion Rate, in addition
to those required by this Section 10.04, as the Board of Directors considers to
be advisable to avoid or diminish any U.S. federal income tax to holders of
Common Stock resulting from any stock dividend or distribution (or rights to
acquire capital stock) or from any event treated as such for income tax
purposes; provided, however, that such increase in the Conversion Rate shall not
adversely affect the interests of the Holders of Securities (after taking into
account U.S. federal income tax and other consequences of such increase).

     To the extent permitted by applicable law and the listing requirements of
The New York Stock Exchange or any national securities exchange on which the
Common Stock is then listed, the Company from time to time may increase the
Conversion Rate by any amount for any period of time if the period is at least
20 days, the increase is irrevocable during the period and the Board of
Directors shall have made a determination that such increase would be in the
best interests of the Company, which determination shall be conclusive. Whenever
the Conversion Rate is increased pursuant to the preceding sentence or the first
paragraph of this Section 10.04(g), the Company shall deliver to the Trustee and
Holders of record of the Securities a notice of the increase at least 15 days
prior to the date the increased Conversion Rate takes effect, and such notice
shall state the increased Conversion Rate and the period during which it shall
be in effect.

     (h) All calculations under this Article 10 shall be made by the Company and
shall be made to the nearest cent or to the nearest one-ten thousandth of a
share, as the case may be, with one half-cent and 0.005 of a share,
respectively, being rounded upward. Notwithstanding the foregoing, no adjustment
need be made for:

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

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

     (iii) the issuance of any shares of Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or convertible security outstanding
as of the date the Securities were first issued, including the issuance of
shares of Common Stock upon the conversion or exchange of any of the Company's
Class B Common Shares outstanding as of the date the Securities were first
issued,

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

     (v) accrued and unpaid Interest, including Additional Interest, if any.

                                       62

<PAGE>

     (i) Whenever the Conversion Rate is adjusted as herein provided, the
Company shall promptly file with the Trustee and any Conversion Agent (if other
than the Trustee) an Officer's Certificate setting forth the Conversion Rate
after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Unless and until a Responsible Officer of the Trustee shall
have received such Officer's Certificate, the Trustee shall not be deemed to
have knowledge of any adjustment of the Conversion Rate and may assume that the
last Conversion Rate of which it has knowledge is still in effect. Promptly
after delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and
the date on which each adjustment becomes effective and shall deliver such
notice of such adjustment of the Conversion Rate to the Holder of each Security
at his last address appearing on the Security register provided for in Section
2.03 of this Indenture, within 20 days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of any such
adjustment.

     (j) In any case in which this Section 10.04 provides that an adjustment
shall become effective immediately after (1) a record date or Ex-Dividend Date
for an event, (2) the date fixed for the determination of shareholders entitled
to receive a dividend or distribution pursuant to Section 10.04(a), (3) a date
fixed for the determination of shareholders entitled to receive rights or
warrants pursuant to Section 10.04(b), (4) the effective date of any subdivision
or combination of Common Stock, or (5) the Expiration Time for any tender or
exchange offer pursuant to Section 10.04(f), (each a "Determination Date"), the
Company may elect to defer until the occurrence of the relevant Adjustment Event
(as hereinafter defined) (x) issuing to the Holder of any Security converted
after such Determination Date and before the occurrence of such Adjustment
Event, the additional shares of Common Stock or other securities issuable upon
such conversion by reason of the adjustment required by such Adjustment Event
over and above the Common Stock issuable upon such conversion before giving
effect to such adjustment and (y) paying to such Holder any amount in cash in
lieu of any fraction pursuant to Section 10.04(a). For purposes of this Section
10.04(j), the term "Adjustment Event" shall mean:

     (i) in any case referred to in clause (1) hereof, the occurrence of such
event,

     (ii) in any case referred to in clause (2) hereof, the date any such
dividend or distribution is paid or made,

     (iii) in any case referred to in clause (3) hereof, the date of expiration
of such rights or warrants,

     (iv) in any case referred to in clause (4) hereof, the date of such
subdivision or combination, and

     (v) in any case referred to in clause (5) hereof, the date a sale or
exchange of Common Stock pursuant to such tender or exchange offer is
consummated and becomes irrevocable.

     (k) For purposes of this Section 10.04, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company shall not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

     Section 10.05 Effect of Reclassification, Consolidation, Merger or Sale.

     (a) If any of the following events occur, namely (i) any reclassification
or change of the outstanding shares of Common Stock (other than a subdivision or
combination to which Section 10.04(c)

                                       63

<PAGE>

applies or a change in par value) as a result of which holders of Common Stock
shall be entitled to receive Exchange Property with respect to or in exchange
for such Common Stock, (ii) any consolidation, merger, binding share exchange or
combination of the Company with another Person as a result of which holders of
Common Stock shall be entitled to receive Exchange Property with respect to or
in exchange for such Common Stock, or (iii) any sale or conveyance of all or
substantially all the properties and assets of the Company to any other Person
as a result of which holders of Common Stock shall be entitled to receive
Exchange Property with respect to or in exchange for such Common Stock, then the
Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental
indenture) providing for the conversion and settlement of the Securities as set
forth in this Indenture. Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 10. If, in the case of any such
reclassification, change, consolidation, merger, binding share exchange,
combination, sale or conveyance, the Exchange Property receivable thereupon by a
holder of Common Stock includes shares of stock or other securities and assets
of a corporation other than the successor or purchasing corporation, as the case
may be, in such reclassification, change, consolidation, merger, binding share
exchange, combination, sale or conveyance, then such supplemental indenture
shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Securities
as the Board of Directors shall reasonably consider necessary by reason of the
foregoing.

     (b) The Conversion Obligation with respect to each $1,000 principal amount
of Securities converted following the effective date of any such transaction,
shall be calculated (as provided in clause (c) below) based on the Exchange
Property. In the event holders of the Common Stock have the opportunity to elect
the form of consideration to be received in such transaction (subject to the
ability of the Company to settle the Conversion Obligation in cash pursuant to
Section 10.03), the Company shall make adequate provision whereby the Holders of
the Securities shall have a reasonable opportunity to determine the form of
consideration, consistent with the election rights and restrictions applicable
to holders of Common Stock, into which all of the Securities, treated as a
single class, shall be convertible from and after the effective date of such
transaction. Such determination shall be made pursuant to Section 1.05 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 in such event and shall be conducted in such a manner as
to be completed by the date which is the earliest of (a) the deadline for
elections to be made by holders of the Common Stock in connection with such
transaction, and (b) two Trading Days prior to the anticipated effective date of
such event. The Company shall provide notice of the opportunity to determine the
form of such consideration, as well as notice of the determination made by
Holders of the Securities by issuing a press release and providing a copy of
such notice to the Trustee. The Company shall not become a party to any such
transaction unless its terms are consistent with the preceding.

     (c) The Conversion Obligation in respect of any Securities converted
following the effective date of any such transaction shall be computed in the
same manner as set forth in Section 10.03(a) except that (1) the Cash Settlement
Averaging Period shall be the 10 Trading Day period beginning on the second
Trading Day after the Conversion Date (or, in the event the Conversion Date is
on the Business Day prior to the Stated Maturity, the 10 Trading Day period
beginning on the second Trading Day after the Stated Maturity), and (2) if the
Securities become convertible into Exchange Property, the Last Reported Sale
Price of the Common Stock shall be deemed to equal the sum of (A) 100% of the
value of any Exchange Property consisting of cash received per share of Common
Stock, (B) the Last Reported Sale Price of any Exchange Property received per
share of Common Stock consisting of securities that are traded on a U.S.
national securities exchange or approved for quotation on The New York Stock
Exchange and (C) the Fair Market Value of any other Exchange Property received
per share, as determined by three independent nationally recognized investment
banks selected by the Company for

                                       64

<PAGE>

this purpose. Settlement (in cash and/or shares) shall occur on the third
Business Day following the final day of such Cash Settlement Averaging Period,
provided, that any amount of the Conversion Settlement Distribution to be
delivered in shares of Common Stock shall be paid in Exchange Property rather
than shares of Common Stock. If the Exchange Property includes more than one
kind of property, the amount of Exchange Property of each kind to be delivered
shall be in the proportion that the value of the Exchange Property (as
calculated pursuant to Section 10.03) of such kind bears to the value of all
such Exchange Property. If the foregoing calculations would require the Company
to deliver a fractional share or unit of Exchange Property to a Holder of
Securities being converted, the Company shall deliver cash in lieu of such
fractional share or unit based on the value of the Exchange Property.

     (d) The Company shall cause notice of the execution of such supplemental
indenture to be delivered to each Holder of Securities, at its address appearing
on the Security register provided for in Section 2.03 of this Indenture, within
20 days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

     (e) The above provisions of this Section 10.05 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, statutory share
exchanges, combinations, sales and conveyances.

     If this Section 10.05 applies to any event or occurrence, Section 10.04
shall not apply.

     Section 10.06 Taxes on Shares Issued.

     The issue of stock certificates on conversions of Securities shall be made
without charge to the converting Holder for any tax in respect of the issue
thereof, except for applicable withholding, if any. The Company shall not,
however, be required to pay any tax or duty which may be payable in respect of
any transfer involved in the issue and delivery of stock in any name other than
that of the Holder of any Securities converted, and the Company shall not be
required to issue or deliver any such stock certificate unless and until the
Person or Persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

     Section 10.07 Reservation of Shares, Shares to Be Fully Paid; Compliance
with Governmental Requirements.

     (a) The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock for the conversion of the Securities from time to time as such
Securities are presented for conversion.

     (b) Before taking any action which would cause an adjustment increasing the
Conversion Rate to an amount that would cause the Conversion Price to be reduced
below the then par value, if any, of the shares of Common Stock issuable upon
conversion of the Securities, the Company shall take all corporate action which
may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at such adjusted
Conversion Rate.

     (c) (i) The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities shall upon issue be fully paid and
non-assessable by the Company and free from all taxes, liens and charges with
respect to the issue thereof.

     (ii) The Company covenants that, if any shares of Common Stock to be
provided for the purpose of conversion of Securities hereunder require
registration with or approval of any governmental

                                       65

<PAGE>

or regulatory authority under any federal or state law, regulation or
requirement (including but not limited to, the shareholder approval rules of The
New York Stock Exchange) before such shares may be validly issued upon
conversion, the Company shall in good faith and as expeditiously as possible, to
the extent then permitted by the rules and interpretations of the SEC (or any
successor thereto), endeavor to secure such registration or approval, as the
case may be.

     Section 10.08 Responsibility of Trustee.

     The Trustee and any other Conversion Agent shall not at any time be under
any duty or responsibility to any Holder of Securities to determine the
Conversion Rate or whether any facts exist which may require any adjustment of
the Conversion Rate, or with respect to the nature or extent or calculation of
any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental indenture provided to be employed, in making the same.
The Trustee and any other Conversion Agent shall not be accountable with respect
to the validity or value (or the kind or amount) of any shares of Common Stock,
or of any securities or property, which may at any time be issued or delivered
upon the conversion of any Security; and the Trustee and any other Conversion
Agent make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any Security for the
purpose of conversion or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article 10. Without limiting the
generality of the foregoing, neither the Trustee nor any Conversion Agent shall
be under any responsibility to determine the correctness of any provisions
contained in any supplemental indenture entered into pursuant to Section 10.05
relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Holders upon the conversion of their
Securities after any event referred to in such Section 10.05 or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Section 7.01, may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon the Officer's Certificate
(which the Company shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.

     Section 10.09 Notice to Holders Prior to Certain Actions.

     In case:

     (a) the Company shall declare a dividend (or any other distribution) on its
Common Stock that would require an adjustment in the Conversion Rate pursuant to
Section 10.04; or

     (b) the Company shall authorize the granting to the holders of all of its
Common Stock of rights or warrants to subscribe for or purchase any share of any
class or any other rights or warrants that would require an adjustment in the
Conversion Rate pursuant to Section 10.04(b); or

     (c) of any reclassification or reorganization of the Common Stock of the
Company (other than a subdivision or combination of its outstanding Common
Stock, or a change in par value, or from par value to no par value, or from no
par value to par value), or of any consolidation, merger or statutory share
exchange to which the Company is a party and for which approval of any
shareholders of the Company is required, or of the sale or transfer of all or
substantially all of the assets of the Company; or

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

the Company shall cause to be filed with the Trustee and to be delivered to each
Holder of Securities at his address appearing on the register provided for in
Section 2.03 of this Indenture, as promptly as

                                       66

<PAGE>

possible but in any event at least ten (10) days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution of rights or warrants, or,
if a record is not to be taken, the date as of which the Holders of Common Stock
of record to be entitled to such dividend, distribution or rights are to be
determined, or (y) the date on which such reclassification, consolidation,
merger, or statutory share exchange, sale, transfer, dissolution, liquidation or
winding up is expected to become effective or occur, and the date as of which it
is expected that holders of Common Stock of record shall be entitled to exchange
their Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, or statutory share exchange, sale,
transfer, dissolution, liquidation or winding up. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, or statutory
share exchange, sale, transfer, dissolution, liquidation or winding up.

     Section 10.10 Shareholder Rights Plan.

     To the extent that the Company has a rights plan in effect upon conversion
of the Securities into Common Stock, a Holder who converts securities shall
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 shall be adjusted at the time of separation as
if the Company distributed to all Holders of Common Stock, shares of the
Company's Capital Stock, evidences of indebtedness or assets as described in
Section 10.04(d) above, subject to readjustment in the event of the expiration,
termination or redemption of such rights. In lieu of any such adjustment, the
Company may amend such applicable shareholder rights plan to provide that upon
conversion of the Securities the Holders shall receive, in addition to the
Common Stock issuable upon such conversion, the rights which would have attached
to such Common Stock if the rights had not become separated from the Common
Stock under such applicable shareholder rights agreement.

     Section 10.11 Unconditional Right of Holders to Convert.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to convert
its Security in accordance with this Article 10 and to bring an action for the
enforcement of any such right to convert, and such rights shall not be impaired
or affected without the consent of such Holder.

     Section 10.12 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 without complying with
The New York Stock Exchange's shareholder approval rules, to the extent
applicable.

                                   ARTICLE 11
                                  SUBORDINATION

     Section 11.01 Agreement of Subordination.

     The Company covenants and agrees, and each Holder of Securities issued
hereunder by its acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article 11; and
each Person holding any Security, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees to be bound by such
provisions.

     The payment of the principal, Interest and Additional Interest, if any, on
all Securities (including, but not limited to, the Redemption Price, the
Repurchase Price and the Fundamental Change Repurchase

                                       67

<PAGE>

Price with respect to the Securities subject to redemption or repurchase in
accordance with Article 3 and the payment of any cash upon conversion in
accordance with Article 10) issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and subject in right of payment to
the prior payment in full in cash or other payment satisfactory to the holders
of Senior Debt of all Senior Debt, whether outstanding at the date of this
Indenture or thereafter incurred.

     No provision of this Article 11 shall prevent the occurrence of any default
or Event of Default hereunder.

     Section 11.02 Payments to Holders.

     (a) No payment shall be made with respect to the principal of, redemption
of, Interest or Additional Interest, if any, or any other amounts due on the
Securities (including, but not limited to, the Redemption Price, the Repurchase
Price and the Fundamental Change Repurchase Price with respect to the Securities
subject to redemption or purchase in accordance with Article 3 and any payment
of cash upon conversion in accordance with Article 10), except (i) payments and
distributions made by the Trustee as permitted by the first or second paragraph
of Section 11.05 and (ii) as set forth in Section 11.08, if:

     (i) a default in the payment of any Designated Senior Debt occurs and is
continuing (or, in the case of Designated Senior Debt for which there is a
period of grace, in the event of such a default that continues beyond the period
of grace, if any, specified in the instrument evidencing such Designated Senior
Debt) (a "Payment Default"); or

     (ii) a default, other than a Payment Default, occurs and is continuing that
then permits holders of such Designated Senior Debt (or any Representative) to
accelerate its maturity (a "Non-Payment Default") and a Responsible Officer of
the Trustee receives at the Corporate Trust Office a written notice of the
default (a "Payment Blockage Notice") from a Representative of Designated Senior
Debt.

          Notwithstanding the foregoing, not more than one Payment Blockage
Notice may be given in any consecutive 365-day period, irrespective of the
number of defaults with respect to Designated Senior Debt during such period. No
default which existed or was continuing on the date of the delivery of any
Payment Blockage Notice with respect to the Designated Senior Debt whose holders
delivered the Payment Blockage Notice may be made the basis of a subsequent
Payment Blockage Notice by the holders of such Designated Senior Debt, whether
or not within a period of 365 consecutive days, unless the default has been
cured or waived for a period of not less than 90 consecutive days.

     The Company may and shall resume payments on and distributions in respect
of the Securities:

     (i) in the case of a Payment Default, upon the date upon which such Payment
Default is cured or waived or ceases to exist, or

     (ii) in the case of a Non-Payment Default, the earlier of (i) the date on
which such Non-Payment Default is cured or waived or ceases to exist, in each
case as and to the extent permitted under the documentation for the Designated
Senior Debt, or (ii) 179 days from after the date on which the applicable
Payment Blockage Notice is received, in each case, unless the maturity of the
Designated Senior Debt has been accelerated in which case the immediately
preceding clause (i) shall become applicable.

                                       68

<PAGE>

     (b) Upon any payment by the Company, or any distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors, in each case upon any dissolution or winding-up or liquidation or
reorganization of the Company (whether voluntary or involuntary) or in
bankruptcy, insolvency, receivership or similar proceedings, all amounts due or
to become due upon all Senior Debt shall first be paid in full in cash, or other
payments satisfactory to the holders of Senior Debt, before any payment of cash,
property or securities is made on account of the principal of, redemption of,
Interest or Additional Interest, if any, on, or with respect to the conversion
of, the Securities (except (i) payments made pursuant to Article 8 from monies
deposited with the Trustee pursuant thereto prior to commencement of proceedings
for such dissolution, winding-up, liquidation or reorganization and (ii) Holders
may receive junior securities as set forth in Section 11.08); and upon any such
dissolution or winding-up or liquidation or reorganization of the Company or
bankruptcy, insolvency, receivership or other proceeding, any payment by the
Company, or any distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the Holders of the Securities
or the Trustee would be entitled, except for the provision of this Article 11,
shall (except as aforesaid) be paid by the Company or by any receiver, trustee
in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders of the Securities or by the Trustee under this
Indenture if received by them or it, directly to the holders of Senior Debt (pro
rata to such holders on the basis of the respective amounts of Senior Debt held
by such holders, or as otherwise required by law or a court order) or their
Representative or Representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Debt may have
been issued, as their respective interests may appear, to the extent necessary
to pay all Senior Debt in full in cash, or other payment satisfactory to the
holders of Senior Debt, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt, before any payment or
distribution is made to the Holders of the Securities or to the Trustee.

     The consolidation of the Company with, or the merger of the Company into,
another corporation or the liquidation or dissolution of the Company following
the conveyance, transfer or lease of all or substantially all its property to
another corporation upon the terms and conditions provided for in Article 5
shall not be deemed a dissolution, winding-up, liquidation or reorganization for
the purposes of this Section 11.02 if such other corporation shall, as a part of
such consolidation, merger, conveyance, transfer or lease, comply with the
conditions stated in Article 5.

     (c) If the payment of the Securities is accelerated because of an Event of
Default, the Company or the Trustee shall promptly notify holders of Senior Debt
or their Representatives of such acceleration. The Company shall not pay the
Securities until five Business Days after the holders or Representatives for the
holders of Senior Debt receive notice of the acceleration and after which the
Company shall pay the Securities only if this Article 11 otherwise permits
payment at that time.

     In the event that, notwithstanding the foregoing provisions, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing, shall be received by the Trustee or the
Holders of the Securities before all Senior Debt is paid in full, in cash or
other payment satisfactory to the holders of Senior Debt, or provision is made
for such payment thereof in accordance with its terms in cash or other payment
satisfactory to the holders of Senior Debt, such payment or distribution shall
be held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Senior Debt or their Representative or Representatives, as their
respective interests may appear, as calculated and directed by the Company, for
application to the payment of all Senior Debt remaining unpaid to the extent
necessary to pay all Senior Debt in full, in cash or other payment satisfactory
to the holders of Senior Debt or their Representative, after giving effect to
any concurrent payment or distribution, or provision therefor, to or for the
holders of such Senior Debt.

                                       69

     Nothing in this Section 11.02 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.10 and Section 7.07. This Section 11.02
shall be subject to the further provisions of Section 11.05.

     Section 11.03 Subrogation of Securities.

     Subject to the payment in full, in cash or other payment satisfactory to
the holders of Senior Debt, of all Senior Debt, the rights of the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Debt pursuant to the provisions of this
Article 11 (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to Senior Debt of the Company
to substantially the same extent as the Securities are subordinated and is
entitled to like rights of subrogation) to the rights of the holders of Senior
Debt to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Debt until the principal, Interest or
Additional Interest, if any, on the Securities shall be paid in full in cash or
other payment satisfactory to the holders of Securities; and, for the purposes
of such subrogation, no payments or distributions to the holders of the Senior
Debt of any cash, property or securities to which the Holders of the Securities
or the Trustee would be entitled except for the provisions of this Article 11,
and no payment pursuant to the provisions of this Article 11, to or for the
benefit of the holders of Senior Debt by Holders of the Securities or the
Trustee, shall, as between the Company, its creditors other than holders of
Senior Debt, and the Holders of the Securities, be deemed to be a payment by the
Company to or on account of the Senior Debt; and no payments or distributions of
cash, property or securities to or for the benefit of the Holders of the
Securities pursuant to the subrogation provisions of this Article 11, which
would otherwise have been paid to the holders of Senior Debt shall be deemed to
be a payment by the Company to or for the account of the Securities. It is
understood that the provisions of this Article 11 are and are intended solely
for the purposes of defining the relative rights of the Holders of the
Securities, on the one hand, and the holders of the Senior Debt, on the other
hand.

     Nothing contained in this Article 11 or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Company and the
Holders of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the principal of,
redemption of, Interest and Additional Interest, if any, on the Securities as
and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the Holders of the
Securities and creditors of the Company other than the holders of the Senior
Debt, nor shall anything herein or therein prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article 11 of the holders of Senior Debt in respect of cash, property or
securities of the Company received upon the exercise of any such remedy.

     Upon any payment or distribution of assets of the Company referred to in
this Article 11, the Trustee, subject to the provisions of Section 7.01, and the
Holders of the Securities shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or to the Holders of the Securities, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Debt and other indebtedness of the Company, the amount thereof or payable
thereon and all other facts pertinent thereto or to this Article 11.

     Section 11.04 Authorization to Effect Subordination.

     Each Holder by its acceptance of a Note agrees to be bound by this Article
11 and authorizes and expressly directs the Trustee, on his behalf, to take such
action as may be necessary or appropriate to effectuate the subordination
between the Holders and the holders of Senior Debt as provided in this Article
11 and appoints the Trustee as attorney-in-fact for any and all such purposes.

     If the Trustee does not file a proof of claim in such proceeding prior to
30 days before the expiration of the time to file a proof of claim in such
proceeding, then the holders of Senior Debt (or their Representative) are hereby
authorized to have the right to file and are (or is) hereby authorized to file,
in the name of the Trustee, a proof of claim for and on behalf of the Holders;
provided that (i) if the holders of the Senior Debt (or their Representative)
file any proof of claim as contemplated above and the Trustee shall subsequently
file a proof of claim in such proceeding before the expiration of the time to
file a proof of claim in such proceeding, such subsequent proof of claim filed
by the Trustee shall supersede any such proof of claim theretofore filed by the
holders of the Senior Debt (or their Representative), and such proof of claim
theretofore filed by the holders of the Senior Debt (or their Representative)
shall thereupon be deemed to be withdrawn, and (ii) the foregoing provisions of
this paragraph shall not be construed to authorize the holders of the Senior
Debt (or their Representative) to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes, or to authorize the holders of the Senior Debt
(or their Representative) to vote in respect of the claim of any Holder in any
such proceeding. This paragraph is intended solely to permit the holders of
Senior Debt to preserve their "turnover right" pursuant to the applicable
subordination provisions in this Article 11 in circumstances where a proof of
claim has not been filed by the Trustee before the expiration of the time to
file a proof of claim in a bankruptcy proceeding, and nothing herein is intended
to impair the rights of the Trustee under Section 6.10 and Section 7.07.

     Section 11.05 Notice to Trustee.

     The Company shall give prompt written notice in the form of an Officer's
Certificate to a Responsible Officer of the Trustee and to any Paying Agent of
any fact known to the Company which would prohibit the making of any payment of
monies to or by the Trustee or any Paying Agent in respect of the Securities
pursuant to the provisions of this Article 11. Notwithstanding the provisions of
this Article 11 or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts which would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article 11, unless and until a
Responsible Officer of the Trustee shall have actual knowledge thereof or
received written notice thereof at the Corporate Trust Office from the Company
(in the form of an Officer's Certificate) or a Representative or a holder or
holders of Senior Debt or from any trustee thereof.

     The Trustee, subject to the provisions of Section 7.01, shall be entitled
to rely on the delivery to it of a written notice by a Representative or a
person representing himself to be a holder of Senior Debt (or a trustee on
behalf of such holder) or Designated Senior Debt to establish that such notice
has been given by a Representative or a holder of Senior Debt or Designated
Senior Debt. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any person as a holder of
Senior Debt or Designated Senior Debt to participate in any payment or
distribution pursuant to this Article 11, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Debt or Designated Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article 11,
and if such evidence is not furnished the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

     Section 11.06 Trustee's Relation to Senior Debt.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 11 in respect of any Senior Debt at any time held by
it, to the same extent as any other holder of Senior Debt, and nothing in
Section 7.11 or elsewhere in this Indenture shall deprive the Trustee of any of
its rights as such holder.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Debt and shall not be liable to any such Holders if the Trustee shall in
good faith mistakenly pay over or distribute to Holders of Securities or to the
Company or to any other person cash, property or securities to which any holders
of Senior Debt shall be entitled by virtue of this Article 11 or otherwise. With
respect to the holders of Senior Debt, the Trustee undertakes to perform or to
observe only such of its covenants or obligations as are specifically set forth
in this Article 11 and no implied covenants or obligations with respect to
holders of Senior Debt shall be read into this Indenture against the Trustee.

     Section 11.07 No Impairment of Subordination.

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

     Section 11.08 Certain Issuances Not Deemed Payment.

     For the purposes of this Article 11 only, the issuance and delivery of
common stock or other securities into which Securities are then convertible upon
conversion of Securities in accordance with Article 10 and the issuance of
junior securities in respect of the Securities shall not be deemed to constitute
a payment or distribution on account of the principal of such Security or
interest. For the purposes of this Article 11, the term "junior securities"
means (a) shares of any Capital Stock of any class of the Company, or (b) debt
of the Company which is subordinated in right of payment to all Senior Debt that
may be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article 11.

     Section 11.09 Obligations Not Impaired.

     Nothing contained in this Article 11 or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Company and the
Holders, the right, which is absolute and unconditional, of the Holder of any
Security to convert such Security in accordance with Article 10.

     Section 11.10 Article Applicable to Paying Agents.

     If at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article 11 shall (unless the context otherwise requires) be
construed as extending to and including such Paying Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this
Article 11 in addition to or in place of the Trustee; provided, however, that
the first paragraph of Section 11.05 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent.

     Section 11.11 Senior Debt Entitled to Rely.

     The holders of Senior Debt (including, without limitation, Designated
Senior Debt) shall have the right to rely upon this Article 11, and no amendment
or modification of the provisions contained herein shall diminish the rights of
such holders unless such holders shall have agreed in writing thereto.

                                   ARTICLE 12
                                   GUARANTEES

     Section 12.01 Guarantee.

     (a) Subject to this Article 12, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Security authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the
Securities or the obligations of the Company hereunder or thereunder, that:

     (1) the principal of, premium and Additional Interest, if any, and interest
on the Securities will be promptly paid in full when due, whether at Stated
Maturity, by acceleration or otherwise, and interest on the overdue principal of
and interest on the Securities, if any, if lawful, and all other obligations of
the Company to the Holders or the Trustee hereunder or thereunder will be
promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and

     (2) in case of any extension of time of payment or renewal of any
Securities or any of such other obligations, that same will be promptly paid in
full when due or performed in accordance with the terms of the extension or
renewal, whether at Stated Maturity, by acceleration or otherwise.

     Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

     (b) The obligations of the Guarantors hereunder are independent of the
obligations of the Company under the Securities and this Indenture and a
separate action or actions may be brought and prosecuted against any Guarantor
whether or not an action or proceeding is brought against the Company and
whether or not the Company is joined in any such action or proceeding. The
liability of the Guarantors hereunder is irrevocable, absolute and unconditional
and (to the extent permitted by law) the liability and obligations of the
Guarantors hereunder shall not be released, discharged, mitigated, waived,
impaired or affected in whole or in part by:

     (i) any defect or lack of validity or enforceability in respect of any
Indebtedness or other obligation of the Company or any other Person under this
Indenture or the Securities, or any agreement or instrument relating to any of
the foregoing;

     (ii) any grants of time, renewals, extensions, indulgences, releases,
discharges or modifications which the Trustee or the Holders may extend to, or
make with, the Company, any Guarantor or any other Person, or any change in the
time, manner or place of payment of, or in any other term of, all or any of the
Obligations under the Indenture or the Securities, or any other amendment or
waiver of, or any consent to or departure from, this Indenture or the
Securities, including any increase or decrease in the Obligations under the
Indenture or the Securities;

     (iii) the taking of security from the Company, any Guarantor or any other
Person, and the release, discharge or alteration of, or other dealing with, such
security;

                                       73

<PAGE>

     (iv) the occurrence of any change in the laws, rules, regulations or
ordinances of any jurisdiction by any present or future action of any
governmental authority or court amending, varying, reducing or otherwise
affecting, or purporting to amend, vary, reduce or otherwise affect, any of the
Obligations under the Indenture or the Securities and the obligations of any
Guarantor hereunder;

     (v) the abstention from taking security from the Company, any Guarantor or
any other Person or from perfecting, continuing to keep perfected or taking
advantage of any security;

     (vi) any loss, diminution of value or lack of enforceability of any
security received from the Company, any Guarantor or any other Person, and
including any other guarantees received by the Trustee;

     (vii) any other dealings with the Company, any Guarantor or any other
Person, or with any security;

     (viii) Trustee's or the Holders' acceptance of compositions from the
Company or any Guarantor;

     (ix) the application by the Holders or the Trustee of all monies at any
time and from time to time received from the Company, any Guarantor or any other
Person on account of any indebtedness and liabilities owing by the Company or
any Guarantor to the Trustee or the Holders, in such manner as the Trustee or
the Holders deems best and the changing of such application in whole or in part
and at any time or from time to time, or any manner of application of
collateral, or proceeds thereof, to all or any of the Obligations under the
Indenture or the Securities, or the manner of sale of any collateral;

     (x) the release or discharge of the Company or any Guarantor of the
Securities or of any Person liable directly as surety or otherwise by operation
of law or otherwise for the Securities, other than an express release in writing
given by the Trustee, on behalf of the Holders, of the liability and obligations
of any Guarantor hereunder;

     (xi) any change in the name, business, capital structure or governing
instrument of the Company or any Guarantor or any refinancing or restructuring
of any of the Obligations under the Indenture or the Securities;

     (xii) the sale of the Company's or any Guarantor's business or any part
thereof;

     (xiii) subject to Section 12.07, any merger or consolidation, arrangement
or reorganization of the Company, any Guarantor, any Person resulting from the
merger or consolidation of the Company or any Guarantor with any other Person or
any other successor to such Person or merged or consolidated Person or any other
change in the corporate existence, structure or ownership of the Company or any
Guarantor or any change in the corporate relationship between the Company and
any Guarantor, or any termination of such relationship;

     (xiv) the insolvency, bankruptcy, liquidation, winding-up, dissolution,

existence;

     (xv) subject to Section 12.07, any arrangement or plan of reorganization
affecting the Company or any Guarantor;

                                       74

<PAGE>

     (xvi) any failure, omission or delay on the part of the Company to conform
or comply with any term of this Indenture;

     (xvii) any limitation on the liability or obligations of the Company or any
other Person under this Indenture, or any discharge, termination, cancellation,
distribution, irregularity, invalidity or unenforceability in whole or in part
of this Indenture;

     (xviii) any other circumstance (including any statute of limitations) that
might otherwise constitute a defense available to, or discharge of, the Company
or any Guarantor; or

     (xix) any modification, compromise, settlement or release by the Trustee,
or by operation of law or otherwise, of the Obligations under the Indenture or
the Securities or the liability of the Company or any other obligor under the
Securities, in whole or in part, and any refusal of payment by the Trustee, in
whole or in part, from any other obligor or other guarantor in connection with
any of the Obligations under the Indenture or the Securities, whether or not
with notice to, or further assent by, or any reservation of rights against, each
of the Guarantors.

     (c) If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or the
Guarantors, any amount paid by either to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, will be reinstated in full
force and effect.

     (d) Each Guarantor hereby waives all rights of subrogation or contribution,
whether arising by contract or operation of law (including, without limitation,
any such right arising under federal bankruptcy law) or otherwise by reason of
any payment by it pursuant to the provisions of this Article 12 until payment in
full of all Obligations under the Indenture, the Securities and the Guarantees.
Each Guarantor further agrees that, as between the Guarantors, on the one hand,
and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) will forthwith become due and payable by the Guarantors for
the purpose of this Guarantee. Each Guarantor that makes a payment or
distribution under its Guarantee shall be entitled to a contribution from each
other Guarantor, if any, so long as the exercise of such right does not impair
the rights of the Holders under the Guarantee, in a pro rata amount based on the
net assets of each Guarantor, determined in accordance with GAAP.

     Section 12.02 Subordination of Guarantees.

     The Obligations of each Guarantor under its Guarantee pursuant to this
Article 12 will be junior and subordinated to the Senior Debt of such Guarantor
on the same basis as the Securities are junior and subordinated to Senior Debt
of the Company. For the purposes of the foregoing sentence, the Trustee and the
Holders will have the right to receive and/or retain payments by any of the
Guarantors only at such times as they may receive and/or retain payments in
respect of the Securities pursuant to this Indenture, including Article 11
hereof.

     Each Holder of Securities, by accepting a Security or a Guarantee,
acknowledges and agrees that the subordination provisions set forth in Article
11 are, and are intended to be, an inducement and consideration to each holder
of Senior Debt, whether such Senior Debt was created or acquired before or after
the issuance of the Securities or the Guarantees, to acquire and continue to
hold, or to continue to hold, such Senior Debt, and such holder of Senior Debt
shall be deemed conclusively to have relied on the

                                       75

<PAGE>

subordination provisions set forth in this Article 12 in acquiring and
continuing to hold, or in continuing to hold, such Senior Debt.

     The provisions of this Section 12.02, insofar as they relate to the
subordination of the Guarantees to Senior Debt of the Company, may not be
amended or modified without the written consent of the holders of all Senior
Debt.

     Section 12.03 Guarantee is in Addition to Other Security.

     This Guarantee shall be in addition to and not in substitution for any
other guarantees which the Trustee may now or hereafter hold in respect of the
Obligations under the Indenture and the Securities owing to the Trustee or the
Holders by the Company and (except as may be required by law) the Trustee shall
be under no obligation to marshal in favor of each of the Guarantors any other
guarantees or any moneys or other assets which the Trustee may be entitled to
receive or upon which the Trustee or the Holders may have a claim.

     Section 12.04 Failure to Exercise Rights Shall Not Operate as a Waiver; No
Suspension of Remedies.

     (a) No failure to exercise and no delay in exercising, on the part of the
Trustee or the Holders, any right, power, privilege or remedy under this Article
12 and this Guarantee shall operate as a waiver thereof, nor shall any single or
partial exercise of any rights, power, privilege or remedy preclude any other or
further exercise thereof, or the exercise of any other rights, powers,
privileges or remedies. The rights and remedies herein provided for are
cumulative and not exclusive of any rights or remedies provided in law or
equity.

     (b) Nothing contained in this Article 12 shall limit the right of the
Trustee or the Holders to take any action to accelerate the maturity of the
Securities pursuant to Article 6 or to pursue any rights or remedies hereunder
or under applicable law.

     Section 12.05 Limitation on Guarantor Liability.

     Each Guarantor that is a Subsidiary of the Company, and by its acceptance
hereof each Holder, hereby confirms that it is the intention of all such parties
that the Guarantee by such Guarantor pursuant to its Guarantee not constitute a
fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law. To effectuate the foregoing intention, the Holders
and such Guarantor hereby irrevocably agree that the obligations of such
Guarantor under its Guarantee shall be limited to the maximum amount which,
after giving effect to all other contingent and fixed liabilities of such
Guarantor, and after giving effect to any collections from or payments made by
or on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under its Guarantee or pursuant to its contribution obligations under
this Indenture, will result in the obligations of such Guarantor under its
Guarantee not constituting such fraudulent transfer or conveyance.

     Section 12.06 Execution and Delivery of Guarantee.

     To evidence its Guarantee set forth in Section 12.01 hereof, each Guarantor
hereby agrees that a notation of such Guarantee substantially in the form
attached as Exhibit F hereto will be endorsed by an Officer of such Guarantor on
each Security authenticated and delivered by the Trustee and that this Indenture
will be executed on behalf of such Guarantor by one of its Officers.

                                       76

<PAGE>

     Each Guarantor hereby agrees that its Guarantee set forth in Section 12.01
hereof will remain in full force and effect notwithstanding any failure to
endorse on each Security a notation of such Guarantee.

     If an Officer whose signature is on this Indenture or on the Guarantee no
longer holds that office at the time the Trustee authenticates the Security on
which a Guarantee is endorsed, the Guarantee will be valid nevertheless.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, will constitute due delivery of the Guarantee set forth in
this Indenture on behalf of the Guarantor.

     In the event that the Company or any of its Subsidiaries creates or
acquires any Domestic Subsidiary after the date of this Indenture, if required
by Section 4.09 hereof, the Company will cause such Domestic Subsidiary to
comply with the provisions of Section 4.09 hereof and this Article 12, to the
extent applicable.

     Section 12.07 Releases.

     (a) In the event that any Guarantor no longer guarantees Indebtedness of
the Company or any of the Subsidiaries of the Company that was incurred, issued
or raised in a public or private U.S. capital markets transaction, other than
the Securities, then such Guarantor will be released and relieved of any
obligations under its Guarantee. Upon delivery by the Company to the Trustee of
an Officer's Certificate and an Opinion of Counsel to the effect that such
Guarantor no longer guarantees such Indebtedness, the Trustee will execute any
documents reasonably required in order to evidence the release of any Guarantor
from its obligations under its Guarantee and this Indenture.

     (b) Upon satisfaction and discharge of this Indenture in accordance with
Article 12 hereof, each Guarantor will be released and relieved of any
obligations under its Guarantee.

     Any Guarantor not released from its obligations under its Guarantee as
provided in this Section 12.07 will remain liable for the full amount of
principal of and interest and premium and Additional Interest, if any, on the
Securities and for the other obligations of any Guarantor under this Indenture
as provided in this Article 12.

                      [FORM OF REVERSE OF GLOBAL SECURITY]

           4.125% Convertible Senior Subordinated Debentures Due 2027

     This Security is one of a duly authorized issue of 4.125% Convertible
Senior Subordinated Debentures Due 2027 (the "Securities") of Invacare
Corporation, an Ohio corporation (including any successor corporation under the
Indenture hereinafter referred to, the "Company"), issued under an Indenture,
dated as of February 12, 2007 (the "Indenture"), among the Company, the
Guarantors and Wells Fargo Bank, N.A., as trustee (the "Trustee"). This Security
is entitled to the benefits of the Guarantees by the Guarantors of the punctual
payment when due and performance of the obligations under the Indenture and this
Security. Reference is made to Article 12 of the Indenture for a statement of
the respective rights, limitations of rights, duties and obligations under the
Guarantees of the Guarantors. The terms of the Security include those stated in
the Indenture, those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended ("TIA"), and those set forth in this Security.
This Security is subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of all such terms. To the extent permitted
by applicable law, in the event of any inconsistency between the terms of this
Security and the terms of the Indenture, the terms of the Indenture shall
control. Capitalized terms used but not defined herein have the meanings
assigned to them in the Indenture unless otherwise indicated.

1.   INTEREST.

     The Securities shall bear interest on the principal amount thereof at a
rate of 4.125% per year. The Company shall pay Additional Interest, if any, as
set forth in the Indenture.

     Interest shall be payable in cash semi-annually in arrears on each Interest
Payment Date to Holders at the close of business on the preceding Interest
Record Date. Interest shall be computed on the basis of a 360-day year comprised
of twelve 30 day months.

     The Company shall pay Interest to the Securityholder of record on the
Interest Record Date even if the Company elects to redeem, or Securityholders
elect to require the Company to repurchase, the Securities on a date that is
after an Interest Record Date but on or prior to the corresponding Interest
Payment Date. In that instance, the Company shall pay accrued and unpaid
Interest on the Securities being redeemed to, but not including, the Redemption
Date, the Repurchase Date or the Fundamental Change Repurchase Date, as the case
may be, in cash to the Securityholder of record on the Interest Record Date.

     If the principal amount of any Security, or any accrued and unpaid
Interest, if any, are not paid when due (whether upon acceleration pursuant to
Section 6.02 of the Indenture, upon the date set for payment of the Redemption
Price pursuant to Section 4 hereof, upon the date set for payment of the
Repurchase Price or Fundamental Change Repurchase Price pursuant to Section 5
hereof, upon the Stated Maturity of the Securities or upon the Interest Payment
Dates), then in each such case the overdue amount shall, to the extent permitted
by law, bear cash interest at the rate of 4.125% per annum, compounded
semi-annually, which interest shall accrue from the date such overdue amount was
originally due to the date payment of such amount, including interest thereon,
has been made or duly provided for. All such interest shall be payable in cash
on demand but if not so demanded shall be paid quarterly to the Holders on the
last day of each quarter.

                                       A-5

<PAGE>

2.   METHOD OF PAYMENT.

     Except as provided below, the Company shall pay Interest, including

amount of $2,000,000 or less, by check mailed to the Holder of such Security and
(iii) any Certificated Security having an aggregate principal amount of more
than $2,000,000, by wire transfer in immediately available funds if requested by
the Holder of any such Security as least five business days prior to the
relevant Interest Payment Date.

     At Stated Maturity, the Company shall pay Interest on Certificated
Securities at the Company's office or agency maintained for that purpose, which
initially shall be the office or agency of the Trustee located at MAC N9303-120,
608-2nd Avenue South, Minneapolis, MN 55479.

     Subject to the terms and conditions of the Indenture, the Company shall

Fundamental Change Repurchase Prices and at Stated Maturity to Holders who
surrender Securities to a Paying Agent to collect such payments in respect of
the Securities. The Company shall pay cash amounts in money of the United States
that at the time of payment is legal tender for payment of public and private
debts. However, the Company may make such cash payments by check payable in such
money.

3.   INDENTURE.

     The Securities are general unsecured obligations of the Company limited to
$135,000,000 aggregate principal amount. The Indenture does not limit other
indebtedness of the Company, secured or unsecured.

4.   REDEMPTION AT THE OPTION OF THE COMPANY.

     No sinking fund is provided for the Securities. The Securities are
redeemable for cash, in whole or in part, on or after February 6, 2012 through
and including February 1, 2017, at a redemption price (the "Redemption Price")
equal to 100% of the principal amount of those Securities, plus accrued and
unpaid Interest and accrued and unpaid Additional Interest, if any, on those
Securities up to, but not including, the Redemption Date if the Last Reported
Sale Price of the Common Stock for at least 20 Trading Days during the period of
30 consecutive Trading Days ending on the last Trading Day is more than 130% of
the Conversion Price in effect on such last Trading Day (such last Trading Day
being no later than February 1, 2017). The Securities are also redeemable for
cash at the option of the Company, in whole or in part, at any time or from time
to time on or after February 1, 2017 upon not less than 30 nor more than 60
days' notice by mail for a Redemption Price equal to 100% of the principal
amount of those Securities plus accrued and unpaid Interest and accrued and
unpaid Additional Interest, if any, on those Securities up to, but not

     In no event shall any Security be redeemable before February 6, 2012.

5.   PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER.

     Subject to the terms and conditions of the Indenture, the Company shall
become obligated to repurchase, at the option of the Holder, all or any portion
of the Securities held by such Holder on February 1, 2017 and February 1, 2022

deliver to the Paying Agent a Repurchase Notice containing the information set

                                       A-6

     At the option of the Holder and subject to the terms and conditions of the
Indenture, the Company shall become obligated to repurchase the Securities held
by such Holder after the occurrence of a Fundamental Change for a Fundamental
Change Repurchase Price equal to 100% of the principal amount of those
Securities plus accrued and unpaid Interest and accrued and unpaid Additional
Interest, if any, on those Securities up to, but not including, the Fundamental
Change Repurchase Date. To exercise such right, a Holder shall deliver to the
Paying Agent a Fundamental Change Repurchase Notice containing the information
set forth in the Indenture at any time on or prior to the close of business on
the second Business Day prior to such Fundamental Change Repurchase Date and
shall deliver the Securities to the Paying Agent as set forth in the Indenture.

     Holders have the right to withdraw any Repurchase Notice or Fundamental
Change Repurchase Notice, as the case may be, by delivering to the Paying Agent
a written notice of withdrawal in accordance with the provisions of the
Indenture.

     If cash sufficient to pay the Repurchase Price or Fundamental Change
Repurchase Price, as the case may be, of all Securities or portions thereof to
be purchased as of the Repurchase Date or the Fundamental Change Repurchase
Date, as the case may be, is deposited with the Paying Agent prior to or on the
Repurchase Date or the Fundamental Change Repurchase Date, as the case may be,
Interest and Additional Interest, if any, shall cease to accrue on such
Securities (or portions thereof) on and following such Repurchase Date or
Fundamental Change Repurchase Date, and the Holder thereof shall have no other
rights as such other than the right to receive the Repurchase Price or
Fundamental Change Repurchase Price upon surrender of such Security.

6.   NOTICE OF REDEMPTION.

     Notice of redemption pursuant to Section 4 of this Security shall be mailed
at least 30 days but not more than 60 days before the Redemption Date to each
Holder of Securities to be redeemed at the Holder's registered address. If money
sufficient to pay the Redemption Price of all Securities (or portions thereof)
to be redeemed on the Redemption Date is deposited with the Paying Agent prior
to or on the Redemption Date, Interest and Additional Interest, if any, shall
cease to accrue on such Securities or portions thereof on and following such
Redemption Date, and the Holder thereof shall have no other rights as such other
than the right to receive the Redemption Price upon surrender of such Security.
Securities in denominations larger than $1,000 principal amount may be redeemed
in part but only in integral multiples of $1,000 of principal amount.

7.   CONVERSION.

     Subject to the occurrence of certain events and in compliance with the
provisions of the Indenture (including, without limitation, the conditions to
conversion of this Security set forth in Section 10.01 thereof), a Holder is
entitled, at such Holder's option, to convert the Holder's Security (or any
portion of the principal amount thereof that is $1,000 or an integral multiple
of $1,000), into cash or a combination of cash and fully paid and nonassessable
shares of Common Stock at the Conversion Rate in effect at the time of
conversion.

     The Company shall notify Holders of any event triggering the right to
convert the Securities as specified in the Indenture.

                                       A-7

<PAGE>

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

     The initial Conversion Rate is 40.3323 shares of Common Stock per $1,000
principal amount, subject to adjustment in certain events described in the
Indenture. The Conversion Rate shall not be adjusted for any accrued and unpaid
Interest or accrued and unpaid Additional Interest, if any. Upon conversion, no
payment shall be made by the Company with respect to accrued and unpaid Interest
and accrued and unpaid Additional Interest, if any. Instead, such amount shall
be deemed paid by the cash and shares of Common Stock, if any, delivered upon
conversion of any Security. In addition, no payment or adjustment shall be made
in respect of dividends on the Common Stock, except as set forth in the
Indenture.

     In addition, following certain corporate transactions as set forth in
Section 10.01(b) of the Indenture that occur on or prior to February 1, 2017 and
that also constitute a Change of Control, a Holder who elects to convert its
Securities in connection with such corporate transaction shall be entitled to
receive Additional Shares of Common Stock upon conversion. Notwithstanding the
previous sentence, in the case of a Public Acquirer Change of Control, the
Company may, in lieu of increasing the Conversion Rate by Additional Shares,
elect to adjust the Conversion Rate and Conversion Obligation such that from and
after the effective date of such Public Acquirer Change of Control, Holders of
the Securities shall be entitled to convert their Securities into a number of
shares of Public Acquirer Common Stock, as determined pursuant to Section
10.01(d) of the Indenture.

     To surrender a Security for conversion, a Holder must (1) complete and
manually sign the Conversion Notice attached hereto (or complete and manually
sign a facsimile of such notice) and deliver such notice to the Conversion
Agent, (2) surrender the Security to the Conversion Agent, (3) if required,
furnish appropriate endorsements and transfer documents, (4) if required by
Section 10.02(f) of the Indenture, pay Interest and Additional Interest and (5)
pay any transfer or similar tax, if required.

     No fractional shares of Common Stock shall be issued upon conversion of any
Security. Instead of any fractional share of Common Stock that would otherwise
be issued upon conversion of such Security, the Company shall pay a cash
adjustment as provided in the Indenture.

     If the Company engages in any reclassification of the Common Stock (other
than a subdivision or combination of its outstanding Common Stock, or a change
in par value, or from par value to no par value, or from no par value to par
value) or is party to a consolidation, merger, binding share exchange or
transfer of all or substantially all of its assets, and as a result of any such
event the Holders of Common Stock would be entitled to receive Exchange Property
for their Common Stock, upon conversion of the Securities after the effective
date of such event, the Conversion Obligation and the Conversion Settlement
Distribution shall be based on the applicable Conversion Rate and the Exchange
Property, in each case in accordance with the Indenture.

8.   SUBORDINATION

     To the extent provided in the Indenture, the Securities and the Guarantees
are subordinated to Senior Debt, as defined in the Indenture, of the Company and
each Guarantor. The Company and each Guarantor agree, and each Holder of
Securities by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give it effect and
appoints the Trustee as attorney-in-fact for such purpose.

                                       A-8

<PAGE>

9.   PAYING AGENT, CONVERSION AGENT AND REGISTRAR.

     Initially, the Trustee shall act as Paying Agent, Conversion Agent and
Registrar. The Company may appoint and change any Paying Agent, Conversion Agent
or Registrar without notice, other than notice to the Trustee. The Company or
any of its Subsidiaries or any of their Affiliates may act as Paying Agent,
Conversion Agent or Registrar.

10.  DENOMINATIONS; TRANSFER; EXCHANGE.

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

11.  PERSONS DEEMED OWNERS.

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

12.  UNCLAIMED MONEY OR SECURITIES.

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

13.  AMENDMENT; WAIVER.

     Subject to certain exceptions set forth in the Indenture, (i) the Indenture
or the Securities may be amended with the written consent of the Holders of at
least a majority in aggregate principal amount of the outstanding Securities and
(ii) certain Events of Defaults may be waived with the written consent of the
Holders of a majority in aggregate principal amount of the outstanding
Securities. Subject to certain exceptions set forth in the Indenture, without
the consent of any Securityholder, the Company and the Trustee may amend the
Indenture or the Securities (i) to add guarantees with respect to the Securities
or secure the Securities, (ii) to remove any guarantee added to the Securities
pursuant to clause (i), unless such guarantee is required pursuant to Section
5.01(a) of the Indenture, (iii) to conform any non-conforming language or
defined terms in the terms in the text of this Indenture or the Securities to
any provision of the "Description of the Debentures" section of the Offering
Memorandum so that such provision in the "Description of the Debentures" section
reflects a verbatim recitation of a provision of this Indenture or the
Securities, (iv) to add to the covenants or Events of Defaults of the Company
for the benefit of the Holders of Securities, (v) to surrender any right or
power conferred upon the Company in the Indenture, (vi) to provide for
conversion rights of Holders of Securities if any reclassification or change of
the Company's Common Stock or any consolidation, merger or sale of all or
substantially all of the Company's assets occurs, (vii) to provide for the
assumption by a successor Person (and the public

                                       A-9

<PAGE>

acquirer, if applicable) of the Company's obligations to the Holders of
Securities in the case of a merger, consolidation, conveyance, transfer, sale,
lease or other disposition as provided under the Indenture and to provide for
the assumption by a successor Guarantor Person of a Guarantor's obligations
under its Guarantee in the case of a merger or consolidation as provided under
the Indenture, (viii) to provide for uncertificated Securities in addition to or
in place of Certificated Securities; provided, however, that uncertificated
Securities are issued in registered form for purposes of Section 163(f) of the
Code, or in a manner such that uncertificated Securities are described in
Section 163(f)(2)(B) of the Code, (ix) to change the Conversion Rate in
accordance with the Indenture; provided, however, that any increase in the
Conversion Rate other than pursuant to Article 10 shall not adversely affect the
interests of the Holders of Securities (after taking into account U.S. federal
income tax and other consequences of such increase), (x) to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA, (xi) to cure any ambiguity or to correct or supplement
any provision in the Indenture which may be a mistake or inconsistent with any
other provision in the Indenture or which is otherwise defective (xii) make
other changes to the Indenture or forms or terms of the Securities, provided
that no such change individually or in the aggregate with all other such changes
have or will have a material adverse effect on the interests of the Holders of
Securities, (xiii) to establish the form of Securities if issued in definitive
form or issue any Securities pursuant to the over-allotment option pursuant to
the Purchase Agreement, (xiv) to evidence and provide for the acceptance of the
appointment under the Indenture of a successor Trustee and (xv) irrevocably
elect to pay the principal of the Securities in cash or to pay all of the
Conversion Obligation in shares of Common Stock.

14.  DEFAULTS AND REMEDIES.

     If any Event of Default with respect to Securities shall occur and be
continuing, the principal amount of the Securities and any accrued and unpaid
Interest and accrued and unpaid Additional Interest, if any, on all the
Securities may be declared due and payable in the manner and with the effect
provided in the Indenture.

15.  TRUSTEE DEALINGS WITH THE COMPANY.

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

16.  CALCULATIONS IN RESPECT OF SECURITIES.

     The Company or its agents shall be responsible for making all calculations
called for under the Securities including, but not limited to, determination of
the market prices for the Securities and of the Common Stock and the amount of
Additional Interest, if any, accrued on the Securities. Any calculations made in
good faith and without manifest error shall be final and binding on Holders of
the Securities. The Company or its agents shall be required to deliver to the
Trustee a schedule of its calculations and the Trustee shall be entitled to
conclusively rely upon the accuracy of such calculations without independent
verification.

17.  NO RECOURSE AGAINST OTHERS.

     A director, officer, employee or shareholder, as such, of the Company or
any Guarantor shall not have any liability for any obligations of the Company or
the Guarantors under the Securities, the Indenture or the Guarantees or for any
claim based on, in respect of or by reason of such obligations or

                                      A-10
