THE SECURITIES
     Section 2.01 Designation; Terms of Securities There is hereby authorized
and established a new series of Securities under Section 3.01 of the Base
Indenture, which series of Securities is designated as the “2.875% Convertible

     (a) Initial Issuance Subject to Section 2.01(b) hereof, the aggregate
principal amount of Securities that may initially be authenticated and delivered

aggregate principal amount of additional Securities purchased by the Underwriter
pursuant to its option to purchase additional Securities set forth in Section 2
of the Underwriting Agreement, which aggregate Principal Amount shall not exceed
$80,000,000). In addition, the Company may execute, in accordance with
Section 3.03 of the Base Indenture, and the Trustee may authenticate, in

of the Base Indenture and Sections 2.04, 3.06 and 10.02 hereof.
     (b) Further Issues. Notwithstanding anything to the contrary provided in
Section 2.01(a) hereof, the Company may, without the consent of the Holders,
issue additional Securities under this Indenture with the same terms and the
same CUSIP number as the Securities initially issued under this Indenture in an
unlimited aggregate principal amount; provided, that the Company may issue such
additional Securities only if they are part of the same issue as the Securities
offered initially issued hereunder for United States federal income tax
purposes.
     (c) Purchases. The Company and its Subsidiaries may also from time to time
repurchase Securities in open market purchases or negotiated transactions
without giving prior

10

--------------------------------------------------------------------------------

 

notice to Holders. Any Securities purchased by the Company or any of its
Subsidiaries will be retired and no longer Outstanding under this Indenture.
     Section 2.02 Denominations Notwithstanding anything to the contrary in
Section 3.05 of the Base Indenture and pursuant to Section 3.01(x) of the Base
Indenture, the Securities will be issued only in minimum denominations of $2,000
and integral multiples of $1,000 in excess thereof.
     Section 2.03 Form of Securities
     (a) General Pursuant to Section 2.01 of the Base Indenture, the Securities
will be substantially in the forms set forth in Exhibit A, hereto, and may
include such insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture, and may have such letters, numbers or
other marks of identification and such legends or endorsements placed thereon as
may be required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities,
as evidenced by their execution of the Securities.
     Each Security will bear a Trustee’s certificate of authentication
substantially in the form set forth in Section 2.02 of the Base Indenture and a
form notice of conversion, form fundamental change repurchase notice and form of
transfer and assignment substantially in the forms set forth in Attachments 1, 2
and 3 to Exhibit A hereto.
     Each Security that is a Global Security will bear a legend substantially in
the form of the legend set forth in Section 3.06 of the Base Indenture (the
“Global Securities Legend”) and shall also bear the “Schedule of Increases and
Decreases of Global Security” set forth in Annex A to Exhibit A hereto.
Notwithstanding Sections 2.01 and 2.02 of the Base Indenture, the Trustee’s
certificate of authentication shall be in the form included in Exhibit A hereto.
     The terms and provisions contained in the Securities will constitute, and
are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.
However, to the extent that any provision of any Security conflicts with the
express provisions of this Indenture, the provisions of this Indenture will
govern and control.
     (b) Initial and Subsequent Form of Securities The Securities initially will
be issued in global form, registered in the name of Cede & Co., as the nominee
of the Depositary, and deposited with the Trustee, at its Corporate Trust
Office, as custodian for the Depositary.
     So long as the Securities are eligible for book-entry settlement with the
Depositary, unless otherwise required by law, and except to the extent provided
in Section 2.04(b)(i) through (iii) hereof, all Securities will be represented
by one or more Global Securities.
     (c) Global Securities Each Global Security will represent the aggregate
principal amount of the then Outstanding Securities endorsed thereon and provide
that it represents such aggregate principal amount of the then Outstanding
Securities, which aggregate principal amount

11

--------------------------------------------------------------------------------

 

may, from time to time, be reduced or increased to reflect transfers, exchanges,
conversions or repurchases by the Company.
     Only the Trustee, or the custodian holding such Global Security for the
Depositary, at the direction of the Trustee, may endorse a Global Security to
reflect the amount of any increase or decrease in the aggregate principal amount
of the then Outstanding Securities represented thereby, and whenever the Holder
of a Global Security delivers instructions to the Trustee to increase or
decrease the aggregate principal amount of the then Outstanding Securities
represented by a Global Security in accordance with this Indenture and the
Applicable Procedures, the Trustee, or the custodian holding such Global
Security for the Depositary, at the direction of the Trustee, will endorse such
Global Security to reflect such increase or decrease in the aggregate principal
amount of the then Outstanding Securities represented thereby. None of the
Trustee, the Company or any agent of the Trustee or the Company will have any
responsibility or bear any liability for any aspect of the records relating to
or payments made on account of the ownership of any beneficial interest in a
Global Security or with respect to maintaining, supervising or reviewing any
records relating to such beneficial interest.
     Section 2.04 Transfer and Exchange
     (a) In General Notwithstanding anything to the contrary in the Base
Indenture, the Company is not required to transfer or exchange any Securities or
portions thereof that have been surrendered for repurchase in accordance with
Article 3 hereof or for conversion in accordance with Article 10 hereof, and a
written form of transfer substantially in the form of the Form of Transfer and
Assignment set forth in Attachment 3 to Exhibit A hereto will be deemed to be a
satisfactory instrument of transfer to the Company and the Security Registrar.
     At such time as all interests in a Global Security have been repurchased,
converted, cancelled or exchanged for Securities in certificated form, such
Global Security shall, upon receipt thereof, be canceled by the Trustee in
accordance with standing procedures and instructions existing between the
Depositary and the custodian for the Global Security. At any time prior to such
cancellation, if any interest in a Global Security is repurchased, converted,
cancelled or exchanged for Securities in certificated form, the principal amount
of such Global Security shall, in accordance with the standing procedures and
instructions existing between the Depositary and the custodian for the Global
Security, be appropriately reduced, and an endorsement shall be made on such
Global Security, by the Trustee or the custodian for the Global Security, at the
direction of the Trustee, to reflect such reduction.
     (b) Global Securities Notwithstanding anything to the contrary in
Section 3.08 of the Base Indenture, every transfer and exchange of a beneficial
interest in a Global Security will be effected through the Depositary in
accordance with the Applicable Procedures and the provisions of this Indenture,
and each Global Security may be transferred only as a whole and only (A) by the
Depositary to a nominee of the Depositary, (B) by a nominee of the Depositary to
the Depositary or to another nominee of the Depositary, or (C) by the Depositary
or any such nominee to a successor Depositary or a nominee of such successor
Depositary.
     Notwithstanding anything to the contrary in Section 3.08 of the Base
Indenture:

12

--------------------------------------------------------------------------------

 

          (i) each Global Security will be exchanged for Definitive Securities
if the Depositary delivers notice to the Company that:
     (A) the Depositary is unwilling or unable to continue to act as Depositary;
or
     (B) the Depositary is no longer registered as a clearing agency under the
Exchange Act;
and, in either case, the Company promptly delivers a copy of such notice to the
Trustee and the Company fails to appoint a successor Depositary within 90 days
after receiving notice from the Depositary.
     (ii) if an Event of Default has occurred and is continuing, any owner of a
beneficial interest in a Global Security may exchange such beneficial interest
for Definitive Securities by delivering a written request to the Security
Registrar.
     (iii) if the Company determines that a Holder is, or will become, an
Affiliate of the Company or was, or will become, a Person that was an Affiliate
of the Company within the three immediately preceding months, the Company may,
at its option, issue to such Holder Definitive Securities in exchange for such
Holder’s beneficial interests in any Global Securities.
     In the case of an exchange for Definitive Securities under clause
(i) above:
          (A) each Global Security will be deemed surrendered to the Trustee for
cancellation;
          (B) the Trustee will cause each Global Security to be cancelled in
accordance with the Applicable Procedures; and
          (C) the Company, in accordance with Section 3.03 of the Base
Indenture, will promptly execute, and, upon receipt of a written request from an
Officer of the Company, the Trustee, in accordance with Section 3.02 of the Base
Indenture, will promptly authenticate and deliver, for each beneficial interest
in each Global Security so exchanged, an aggregate principal amount of
Definitive Securities equal to the aggregate principal amount of such beneficial
interest, registered in such names and in such authorized denominations as the
Depositary specifies, and bearing any legends that such Definitive Securities
are required to bear under this Indenture.
     In the case of an exchange for Definitive Securities under clause
(ii) above:
          (A) the Security Registrar will deliver notice of such request to the
Company and the Trustee, which notice will identify the owner of the beneficial
interest to be exchanged, the aggregate principal amount of such beneficial
interest and the CUSIP of the relevant Global Security;

13

--------------------------------------------------------------------------------

 

          (B) the Company, in accordance with Section 3.03 of the Base
Indenture, will promptly execute, and, upon receipt of a written request from an
Officer of the Company, the Trustee, in accordance with Section 3.02 of the Base
Indenture, will promptly authenticate and deliver to such owner, for the
beneficial interest so exchanged by such owner, Definitive Securities registered
in such owner’s name having an aggregate principal amount equal to the aggregate
principal amount of such beneficial interest and bearing any legends that such
Definitive Securities are required to bear under this Indenture; and
          (C) the Security Registrar, in accordance with the Applicable
Procedures, will cause the principal amount of such Global Security to be
decreased by the aggregate principal amount of the beneficial interest so
exchanged. If all of the beneficial interests in a Global Security are so
exchanged, such Global Security will be deemed surrendered to the Trustee for
cancellation, and the Trustee will cause such Global Security to be cancelled in
accordance with the Applicable Procedures.
     In the case of an exchange for Definitive Securities under clause
(iii) above:
          (A) the Company will deliver notice of such request to the Security
Registrar and the Trustee, which notice will identify the owner of the
beneficial interest to be exchanged, the aggregate principal amount of such
beneficial interest and the CUSIP of the relevant Global Security;
          (B) the Company, in accordance with Section 3.03 of the Base
Indenture, will promptly execute, and, upon receipt of a written request from an
Officer of the Company, the Trustee, in accordance with Section 3.02 of the Base
Indenture, will promptly authenticate and deliver to such owner Definitive
Securities registered in such owner’s name having an aggregate principal amount
equal to the aggregate principal amount of the beneficial interest so exchanged
and bearing any legends that such Definitive Securities are required to bear
under this Indenture and any applicable law; and
          (C) the Security Registrar, in accordance with the Applicable
Procedures, will cause the principal amount of each relevant Global Security to
be decreased by the aggregate principal amount of the beneficial interest so
exchanged. If all of the beneficial interests in a Global Security are so
exchanged, such Global Security will be deemed surrendered to the Trustee for
cancellation, and the Trustee will cause such Global Security to be cancelled in
accordance with the Applicable Procedures.
     (c) Definitive Securities Except as otherwise provided in Section 2.04(a)
hereof, Definitive Securities may be transferred or exchanged in accordance with
Section 3.07 of the Base Indenture.
     Section 2.05 Payments on the Securities
     (a) In General Each Security will accrue interest at a rate equal to 2.875%
per annum from the most recent date to which interest has been paid or duly
provided for, or, notwithstanding Section 3.05 of the Base Indenture, if no
interest has been paid or duly provided for, the Issue Date. Interest on a
Security will cease to accrue upon the earliest of the Maturity Date, subject to
the provisions of Article 10 hereof, any Conversion Date for such Security and,

14

--------------------------------------------------------------------------------

 

subject to the provisions of Article 3 hereof, any Fundamental Change Repurchase
Date for such Security. Interest on any Security will be payable semi-annually
in arrears on each Interest Payment Date, beginning July 15, 2011, to the Holder
of such Security as of the Close of Business on the Regular Record Date
immediately preceding the applicable Interest Payment Date. As provided in
Section 3.12 of the Base Indenture, interest will be computed on the basis of a
360-day year comprised of twelve 30-day months. Pursuant to Section 6.05 hereof,
in certain circumstances, the Company may be obligated to pay Holders Additional
Interest.
     The Securities will mature on the Maturity Date, and on the Maturity Date,
each Holder of a then Outstanding Security will be entitled on such date to
receive $1,000 in cash for each $1,000 in principal amount of then Outstanding
Securities held, together with accrued and unpaid interest to, but not
including, the Maturity Date on such then Outstanding Securities.
     If the Maturity Date or any Interest Payment Date or Fundamental Change
Repurchase Date falls on a day that is not a Business Day, then any action to be
taken on such date need not be taken on such date, but may be taken on the
immediately following Business Day with the same force and effect as if taken on
such date, and no additional interest will accrue on account of such delay.
     (b) Method of Payment The Company will pay the principal of, the
Fundamental Change Repurchase Price for, and any cash portion of the Conversion
Obligation with respect to, any Definitive Security to the Holder of such
Security in cash at the designated office of the Paying Agent in the borough of
Manhattan in The City of New York, New York, on the relevant payment or
settlement date, as the case may be. The Company will pay any interest on any
Definitive Security to the Holder of such Security (i) if such Holder holds
$5,000,000 or less aggregate principal amount of Securities, by check mailed to
such Holder’s registered address, and (ii) if such Holder holds more than
$5,000,000 aggregate principal amount of Securities, (A) by check mailed to such
Holder’s registered address or, (B) if such Holder delivers to the Registrar a
written request that the Company make such payments by wire transfer to an
account of such Holder within the United States, for each interest payment
corresponding to each Regular Record Date occurring during the period beginning
on the date on which such Holder delivered such request and ending on the date,
if any, on which such Holder delivers to the Registrar a written instruction to
the contrary, by wire transfer of immediately available funds to the account
specified by such Holder.
     The Company will pay the principal of, interest on, the Fundamental Change
Repurchase Price for, and any cash portion of the Conversion Obligation with
respect to, any Global Security to the Depositary by wire transfer of
immediately available funds on the relevant payment date.
     (c) Defaulted Amounts Whenever any amount payable on a Security (including,
the principal of, the Fundamental Change Repurchase Price for, and interest on,
such Security) has become due and payable, but the Company fails to punctually
pay or duly provide for such amount (any such amount, a “Defaulted Amount”),
such Defaulted Amount will forthwith cease to be payable to the Holder of such
Security on the relevant payment date by virtue of its having been due such
payment on such payment date, but will instead, to the extent permitted under
applicable law, accrue interest (“Default Interest”) at a rate equal to the
stated rate of interest on the Securities from, and including, such payment date
and to, but excluding, the date on which

15

--------------------------------------------------------------------------------

 

such Defaulted Amount is paid by the Company in accordance with either clause
(i) or (ii) below.
          (i) The Company may elect to pay any Defaulted Amount and Default
Interest on such Defaulted Amount to the Persons in whose names the Securities
(or their respective predecessor Notes) are registered at the Close of Business
on a special record date for the payment of such Defaulted Amount and Default
Interest (a “Special Regular Record Date”) fixed in accordance with the
following procedures:
     (A) At least 30 days before the date on which the Company proposes to pay
such Defaulted Amounts and Default Interest thereon, the Company will deliver to
the Trustee written notice of (i) the proposed payment date for such Defaulted
Amounts and Default Interest thereon and (ii) the aggregate amount of such
Defaulted Amounts and Default Interest thereon.
     (B) Simultaneously with delivering such notice to the Trustee, the Company
will either (i) deposit with the Trustee an amount of money, in immediately
available funds, equal to the aggregate amount of such Defaulted Amounts and
Default Interest thereon, or (ii) take other actions that the Trustee deems
reasonably satisfactory to ensure that an amount of money, in immediately
available funds, equal to the aggregate of such Defaulted Amounts and Default
Interest thereon will be deposited with the Trustee by 10:00 a.m., New York City
time, on the day that is five Business Days prior to the proposed payment date,
and in either case, upon receipt of such money, the Trustee will hold such money
in trust for the benefit of the Persons entitled to such Defaulted Amounts and
Default Interest pursuant to this Section 2.05(c)(i).
     (C) Upon (i) receipt of such notice and (ii) the Company’s depositing such
money or taking such other actions reasonably satisfactory to the Trustee, the
Company will promptly fix a Special Regular Record Date for the payment of such
Defaulted Amounts and Default Interest thereon, which Special Regular Record
Date will be not more than 15 calendar days and not less than 10 days prior to
the proposed payment date, and notify the Trustee of the Special Regular Record
Date. The Trustee will then, in the name and at the expense of the Company,
deliver notice to each Holder specifying such Special Regular Record Date and
the date on which such Defaulted Amounts and Default Interest thereon will be
paid by the Company.
     (D) After such notice has been delivered by the Trustee, such Defaulted
Amounts and Default Interest thereon will be paid to the Persons in whose names
the Notes (or their respective predecessor Notes) are registered at the Close of
Business on the Special Regular Record Date specified in such notice and such
Defaulted Amounts and Default Interest thereon will no longer be payable
pursuant to the following clause (ii) of this Section 2.05(c)(i).
          (ii) The Company may pay any Defaulted Amounts and Default Interest on
such Defaulted Amounts in any other lawful manner that is not inconsistent with
the

16

--------------------------------------------------------------------------------

 

requirements of any securities exchange or automated quotation system on which
the Notes are then listed (or, if applicable, have been listed) or designated
for issuance, and upon such notice as may be required by such exchange or
automated quotation system, if, after notice given by the Company to the Trustee
of the proposed payment pursuant to this clause, such manner of payment will be
deemed practicable by the Trustee.
     (d) Money for Securities Payments to be Held in Trust Each reference in
Section 4.03 of the Base Indenture to “principal of or any premium or interest”,
“principal and any premium and interest”, “principal of (and premium, if any) or
interest, if any,” and “principal, premium or interest” is hereby replaced with
a reference to “principal of, interest on, Fundamental Change Repurchase Price
with respect to, or cash portion of the Conversion Obligation due ”.
ARTICLE 3
FUNDAMENTAL CHANGES AND REPURCHASES THEREUPON
     Section 3.01 Fundamental Change Permits Holders to Require the Company to
Repurchase the Securities
     (a) General If a Fundamental Change occurs at any time, each Holder will
have the right, at its option, to require the Company to repurchase for cash, at
the Fundamental Change Repurchase Price, (i) all of such Holder’s Securities or
(ii) any portion of such Holder’s Securities such that the principal amount that
remains Outstanding of each Security of such Holder that is not repurchased in
full equals $2,000 or an integral multiple of $1,000 in excess thereof.
     (b) Fundamental Change Repurchase Price The “Fundamental Change Repurchase
Price” means, for any Securities to be repurchased on a Fundamental Change
Repurchase Date, a price equal to 100% of the principal amount of such
Securities to be repurchased, plus accrued and unpaid interest to, but
excluding, such Fundamental Change Repurchase Date; provided, however, that if a
Fundamental Change Repurchase Date occurs after a Regular Record Date, but on or
prior to the Interest Payment Date corresponding to such Regular Record Date,
the Company will instead pay the full amount of accrued and unpaid interest to
the Holder of record on such Regular Record Date and the Fundamental Change
Repurchase Price will be equal to 100% of the principal amount of the Securities
to be repurchased.
     (c) Fundamental Change Repurchase Date The “Fundamental Change Repurchase
Date” means, for any Fundamental Change, the date specified by the Company in
the Fundamental Change Notice for such Fundamental Change, which date will be
not less than 30 Business Days, nor more than 45 Business Days, following the
Fundamental Change Notice Date for such Fundamental Change.
     Section 3.02 Fundamental Change Notice (a) General On or before the 20th
calendar day after the occurrence of a Fundamental Change, the Company will
deliver to each Holder notice of the occurrence of such Fundamental Change and
of the resulting repurchase right (the “Fundamental Change Notice,” and the date
of such delivery, the “Fundamental Change

17

--------------------------------------------------------------------------------

 

Notice Date”). Simultaneously with delivering any Fundamental Change Notice, the
Company will publish notice in a newspaper of general circulation in The City of
New York, New York on the Company’s website, or through such other public medium
as the Company may use at that time, which notice will contain the same
information as such Fundamental Change Notice.
     For any Fundamental Change, the Fundamental Change Notice shall state:
     (i) the events causing such Fundamental Change;

     (iii) the last date on which a Holder may exercise its right to require the
Company to repurchase its Securities as a result of such Fundamental Change

amount of Securities for such Fundamental Change;
     (v) the Fundamental Change Repurchase Date for such Fundamental Change;
     (vi) the name and address of the Paying Agent and the Conversion Agent;
     (vii) if applicable, the Conversion Rate and any adjustments to the
Conversion Rate;
     (viii) if applicable, that the Securities with respect to which a
Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if such Holder withdraws such Fundamental Change Repurchase
Notice in accordance with the terms of this Indenture or to the extent that a
portion of such Securities is not subject to such Fundamental Change Repurchase
Notice; and
     (ix) the procedures that a Holder must follow to require the Company to
repurchase a Security.
     (b) Failure or Defect Notwithstanding anything to the contrary contained
elsewhere in this Indenture, neither the failure of the Company to deliver a
Fundamental Change Notice nor a defect in a Fundamental Change Notice delivered
by the Company will limit the repurchase rights of any Holder under this
Article 3 or impair or otherwise affect the validity of any proceedings relating
to the repurchase of any Security pursuant to this Article 3.
     Section 3.03 Fundamental Change Repurchase Notice
     (a) General. To exercise its repurchase rights under Section 3.01(a) hereof
with respect to any Fundamental Change, a Holder must deliver to the Paying
Agent, by the Close of Business on the Business Day immediately preceding the
Fundamental Change Repurchase Date:

18

--------------------------------------------------------------------------------

 

     (i) a duly completed “Form of Fundamental Change Repurchase Notice” in the
form of Attachment 2 of the Securities that such Holder is tendering for
repurchase (a “Fundamental Change Repurchase Notice”); and
     (ii) the Securities that such Holder is tendering for repurchase, (A) by
book-entry transfer if such Securities are Global Securities, or (B) by physical
delivery, if such Securities are Definitive Securities, in each case, together
with any endorsements or other documents reasonably requested by the Paying
Agent.
     (b) Contents of Fundamental Change Repurchase Notice The Fundamental Change
Repurchase Notice for any Security must state:
          (i) if such Security is to be repurchased in part, the principal
amount of such Security to be repurchased, which principal amount must be such
that the principal amount that will not be repurchased equals $2,000 or an
integral multiple of $1,000 in excess thereof;
          (ii) that such Security will be repurchased by the Company pursuant to

Trustee an Officers’ Certificate upon the occurrence of any Default or Event of
Default in accordance with Section 4.05 of the Base Indenture.

specified in Sections 6.02(vii) or 6.02(viii) hereof occurs with respect to the

provision of the Securities or this Indenture.
     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of the Securities in the proceeding. A
delay or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default will 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 6.05 Sole Remedy for Failure to Report
     (a) General Notwithstanding anything to the contrary in the Securities or
in this Indenture, and notwithstanding the remedies afforded to Holders of the
Securities upon the occurrence and continuation of an Event of Default as set
forth in Sections 6.03 and 6.04 hereof, to the extent the Company elects, the
sole remedy for an Event of Default relating to the Company’s failure to comply
with its reporting obligations under Section 4.04 of this Supplemental Indenture
(any such default, a “Reporting Default”), will, after the occurrence of such
Reporting Default, consist exclusively of the right to receive additional
interest on the Securities (“Additional Interest”) at a rate equal to 1.00% per
annum on the principal amount of then Outstanding Securities for each day during
the 180-day period beginning on, and including, the date on which such Reporting
Default first occurred during which such Reporting Default is continuing and has
not been cured or waived.
     If the Company so elects, such Additional Interest will be payable in the
same manner and on the same dates as the stated interest payable on the
Securities. On the 181st day after the occurrence of the Reporting Default (if
such Reporting Default have not been cured or waived prior to such 181st day),
the Securities will be subject to acceleration as provided in Section 6.03 of
this Supplemental Indenture.
     (b) Company Election Notice In order to elect to pay the Additional
Interest as the sole remedy during the first 180 days after the occurrence of a
Reporting Default in accordance with Section 6.05(a) and (b) hereof, the Company
must notify the Holders of such election prior to the beginning of such 180-day
period.
     (c) Limitation on Remedy
          (i) On the 181st day after the occurrence of such Reporting Default
(if such Reporting Default is not cured or waived prior to such 181st day), the
Securities will immediately be subject to acceleration in accordance with
Section 6.03 hereof.
          (ii) In addition, if a Reporting Default occurs and the Company fails
to timely elect to pay Additional Interest pursuant to Section 6.05(b) hereof,
the Securities will immediately be subject to acceleration pursuant to
Section 6.03 hereof on account of such Reporting Default.
          (iii) Notwithstanding anything to the contrary herein, if the Company
elects to pay the Additional Interest with respect to any Reporting Default, the
Company’s election will not affect the rights of any Holder with respect to any
other Event of Default.
     Section 6.06 Waiver of Past Defaults. If an Event of Default or a Default,
other than (a) an uncured Event of Default described in Sections 6.02(a)(i),
6.02(a)(ii) or 6.02(a)(iii) hereof or (b) a Default in respect of a provision
that under Section 9.03 hereof cannot be amended without the consent of each
affected Holder, the Holders of a majority in aggregate principal amount of the
then Outstanding Securities may waive such Event of Default or Default and all
of its consequences hereunder. Whenever any Event of Default is so waived, it
will cease to exist, and whenever any Default is so waived, it will be deemed
cured, and any Event of Default

--------------------------------------------------------------------------------

 

arising therefrom will be deemed not to occur. However, no such waiver will
extend to any subsequent or other Default or Event of Default or impair any
consequent right.
     Section 6.07 Control by Majority At any time, the Holders of a majority of
the aggregate principal amount of the then Outstanding Securities may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or for exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture or, subject to the Trustee’s duties under Article 6 of the
Base Indenture and the Trust Indenture Act, that the Trustee determines to be
unduly prejudicial to the rights of a Holder or to the Trustee, or that would
potentially involve the Trustee in personal liability unless the Trustee is
offered indemnity or security reasonably satisfactory to it against any loss,
liability or expense to the Trustee that may result from the Trustee’s
instituting such proceeding as the Trustee. Prior to taking any action
hereunder, the Trustee will be entitled to indemnification reasonably
satisfactory to it against all losses and expenses caused by taking or not
taking such action.
     Section 6.08 Limitation on Suits Subject to Section 6.09 hereof, no Holder
may pursue a remedy with respect to this Indenture or the Securities unless:
     (a) such Holder has previously delivered to the Trustee written notice that
an Event of Default has occurred and is continuing;
     (b) the Holders of at least 25% of the aggregate principal amount of the
then Outstanding Securities deliver to the Trustee a written request that the
Trustee pursue a remedy with respect to such Event of Default;
     (c) such Holder or Holders have offered and, if requested, provided to the
Trustee security or indemnity reasonably satisfactory to the Trustee against any
loss, liability or other expense of compliance with such written request;
     (d) the Trustee has not complied with such written request within 60 days
after receipt of such written request and offer of security or indemnity; and
     (e) during such 60-day period, the Holders of a majority of the aggregate
principal amount of the then Outstanding Securities did not deliver to the
Trustee a direction inconsistent with such written request.
     A Holder may not use this Indenture to prejudice the rights of any other
Holder or to obtain a preference or priority over any other Holder, it being
understood that the Trustee does not have any affirmative duty to ascertain
whether any usage of this Indenture by a Holder is unduly prejudicial to such
other Holders.
     Section 6.09 Rights of Holders to Receive Payment and to Convert
Notwithstanding anything to the contrary elsewhere in this Indenture, the right
of any Holder to receive payment of the principal of, Fundamental Change
Repurchase Price for, and accrued and unpaid interest on, its Securities, on or
after the respective due date, and to convert its Securities and receive the
Conversion Obligation due with respect to such Securities in accordance with
Article 10 hereof, or to bring suit for the enforcement of any such payment or
conversion rights, will not be

30

--------------------------------------------------------------------------------

 

impaired or affected without the consent of such Holder and will not be subject
to the requirements of Section 6.08 hereof.
     Section 6.10 Collection Suit by Trustee If an Event of Default specified in
Section 6.02(a)(i), 6.02(a)(ii) or 6.02(a)(iii) hereof occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as trustee of
an express trust against the Company for the whole amount of principal of,
interest on, Fundamental Change Repurchase Price for, and Conversion Obligation
with respect to, the Securities, as the case may be, and, to the extent lawful,
any Default Interest on such principal, interest and Fundamental Change
Repurchase Price, and such further amount as is sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, as well as
any other amounts that may be due under Section 6.07 of the Base Indenture.
     Section 6.11 Trustee May Enforce Claims Without Possession of Securities
     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders in respect of which such judgment has been recovered.
     Section 6.12 Trustee May File Proofs of Claim The Trustee is authorized to
file such proofs of claim and other papers or documents as may be necessary or
advisable to have the claims of the Trustee and the Holders allowed in any
judicial proceedings relative to the Company, its creditors or its property and,
unless prohibited by law or applicable regulations, will be entitled to collect,
receive and distribute any money or other property payable or deliverable on any
such claims, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and, in the
event that the Trustee consents to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.07 of the
Base Indenture. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 6.07 of the Base Indenture out
of the estate in any such proceeding, will be denied for any reason, payment of
the same will be secured by a lien on, and is paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding, whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained will be deemed to authorize the Trustee to authorize or consent to, or
to accept or to adopt on behalf of any Holder, any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of
any Holder, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

     Section 6.13 Restoration of Rights and Remedies If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then and in
every such case, subject to any determination in such proceeding, the Company,
the Trustee and the Holders shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.
     Section 6.14 Rights and Remedies Cumulative Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities in Section 3.09 of the Base Indenture, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.
     Section 6.15 Delay or Omission Not a Waiver No delay or omission of the
Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given
by this Article 6 or by law to the Trustee or to the Holders may be exercised
from time to time and as often as may be deemed expedient by the Trustee
(subject to the limitations contained in this Indenture) or by the Holders, as
the case may be.
     Section 6.16 Priorities If the Trustee collects any money pursuant to this
Article 6, it will pay out the money in the following order:
     FIRST: to the Trustee, its agents and attorneys for amounts due under
Section 6.07 of the Base Indenture, including payment of all compensation,
expenses and liabilities incurred, and all advances made, by the Trustee and the
costs and expenses of collection;
     SECOND: to the Holders, for any amounts due and unpaid on the principal of,
Fundamental Change Repurchase Price for, accrued and unpaid interest on, and
cash portion of the Conversion Obligation with respect to, any Security, without
preference or priority of any kind, according to such amounts due and payable on
all of the Securities; and
     THIRD: the balance, if any, to the Company or to such other party as a
court of competent jurisdiction directs.
     The Trustee may fix a record date and payment date for any payment to the
Holders pursuant to this Section 6.16. If the Trustee so fixes a record date and
a payment date, at least 15 days prior to such record date, the Company will
deliver to each Holder and the Trustee a written notice, which notice will state
such record date, such payment date and the amount of such payment.
     Section 6.17 Undertaking for Costs All parties to this Indenture agree, and
each Holder of a Security, by such Holder’s acceptance thereof, shall be deemed
to have agreed, that

32

--------------------------------------------------------------------------------

 

any court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; provided,
however, that the provisions of this Section 6.17 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in aggregate principal amount of
the Securities then Outstanding, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of, the Fundamental change
Repurchase Price with respect to, or accrued and unpaid interest, if any, on any
Note on or after the due date expressed or provided for in such Note or to any
suit for the enforcement of the right to convert any Note in accordance with the
provisions of Article 10 hereof.
     Section 6.18 Waiver of Stay, Extension and Usury Laws The Company covenants
that, to the extent that it may lawfully do so, it will not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law wherever enacted, now or at any time
hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Company, to the extent that it may lawfully do so, hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will instead suffer and permit the
execution of every such power as though no such law has been enacted.

not have the right to redeem the Securities prior to the Maturity Date, the
Securities will not have the benefit of a sinking fund, and pursuant to

33

--------------------------------------------------------------------------------

 

     (b) Amendment to the Base Indenture The reference to “3.11, 11.02 or 12.01”
in Section 3.01 of the Base Indenture shall, with respect to the Securities, be
deemed replaced with “or 3.11”.
     Section 8.03 Discharge of Liability on Securities When (a)(i) the Company
delivers to the Registrar all Outstanding Securities (other than Securities
replaced pursuant to Section 3.09 of the Base Indenture) for cancellation or
(ii) all Outstanding Securities have become due and payable, whether on the
Maturity Date, any Fundamental Change Repurchase Date, upon conversion or
otherwise, and the Company irrevocably deposits with the Trustee or delivers to
the Holders, as applicable, cash and/or shares of Common Stock (solely to
satisfy any outstanding Conversion Obligation with respect to the Securities),
sufficient to pay or deliver, as the case may be, all amounts due and owing on
all Outstanding Securities (other than Securities replaced pursuant to
Section 3.09 of the Base Indenture) and (b) the Company pays all other sums
payable by it under this Indenture, then, this Indenture will cease to be of
further effect with respect to the Securities and the Holders and the Trustee
will acknowledge the satisfaction and discharge of this Indenture with respect
to the Securities; provided, however, that Sections 2.05, 3.07, 3.08, 4.01,
4.02, 4.03, 4.07, 10.03, 10.06, 10.07 hereof, Sections 3.12, 3.13, 4.03 of the
Base Indenture (as amended by this Supplemental Indenture) and Article 8 hereof
will survive any discharge of this Indenture until such time as the Securities
have been paid in full and there are no Securities Outstanding; provided,
further, that any obligation of the Company to the Trustee under Sections 4.03
or 6.07 of the Base Indenture shall survive after the Securities are paid in
full and there are no Securities Outstanding.
     Section 8.04 Deposited Moneys to Be Held in Trust Subject to Section 8.05
hereof, all cash and/or shares of Common Stock, if any, deposited with the
Trustee pursuant to Section 8.02 hereof will be held in trust for the sole
benefit of the Holders, and such cash and/or shares of Common Stock, if any,
will be applied by the Trustee, either directly or through the Paying Agent, to
the payment of the obligation for which such cash and shares of Common Stock, if
any, have been deposited with the Trustee.
     Section 8.05 Paying Agent to Repay Monies Held Upon the satisfaction and
discharge of this Supplemental Indenture, all cash and shares of Common Stock,
if any, then held by the Paying Agent (if other than the Trustee) shall, upon

property law, the Trustee and the Paying Agent, upon receiving a written request
from the Company, will promptly turn over to the Company any cash or shares of
the Common Stock held for payment on the Securities that remains unclaimed two
years after the date on which such payment was due. After the Trustee and the
Paying Agent return such cash and shares of Common Stock, the Trustee and the
Paying Agent will have no further liability to any Holder with respect to such
cash and shares of Common Stock, and any Holder entitled to the payment of such
cash or shares of the Common Stock under the Securities or this Indenture must
look to the Company for payment as general creditor of the Company.

apply any cash or shares of Common Stock in accordance with Section 8.03 hereof
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 of this
Supplemental Indenture until such time as the Trustee or the Paying Agent is
permitted to apply all such cash and shares of Common Stock, if any, in
accordance with Section 8.03 hereof; provided, however, that if the Company
makes any payment of the principal of, interest on, Fundamental Change
Repurchase Price for, or cash portion of the Conversion Obligation with respect
to, any Security following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders to receive such payment from
any cash and shares of Common Stock, if any, held by the Trustee or Paying
Agent.

ARTICLE 10
CONVERSIONS
     Section 10.01 Right to Convert Subject to and upon compliance with the
provisions of this Indenture, a Holder will have the right, at such Holder’s
option, to convert its Securities, or any portion of such Securities such that
the principal amount that is not converted of each Security that is not
converted in full equals $2,000 or an integral multiple of $1,000 in excess
thereof, into an amount of cash and a number of shares of Common Stock, if any,
determined in accordance with Section 10.03 hereof, based on a conversion rate
initially equal to 19.5160 shares of Common Stock (and subject to adjustment as
provided in Sections 10.05, 10.06 and 10.07 hereof) per $1,000 principal amount
of Securities (the “Conversion Rate”), at any time until the second Scheduled
Trading Day immediately preceding the Maturity Date.
     Section 10.02 Conversion Procedures
     (a) General To exercise its conversion privilege with respect to a
beneficial interest in a Global Security or with respect to a Certificated
Security, the Holder of such Security must:
     (i) pay any funds required under Section 10.02(d) hereof;
     (ii) pay any taxes or duties required under the proviso of Section 10.02(e)
hereof; and
     (iii) if such Security is a Global Security, (A) complete any instruction
form required by the Depositary to effect the conversion of a beneficial
interest under the Applicable Procedures; and (B) otherwise comply with the
Applicable Procedures of the Depositary in effect on the date such Holder seeks
to convert such beneficial interest; or
     (iv) if such Security is a Definitive Security, (A) complete and manually
sign the conversion notice on the back of the Security (the “Conversion
Notice”), or a facsimile of the Conversion Notice; (B) deliver the Conversion
Notice (or facsimile thereof), which is irrevocable, and the Security to the
Conversion Agent; and, (C) if required, furnish appropriate endorsements and
transfer documents.
     In addition, if a Holder has already delivered a Fundamental Change
Repurchase Notice with respect to a Security in accordance with Section 3.03
hereof, except to the extent that a portion of such Security is not subject to a
Fundamental Change Repurchase Notice, the Holder

37

--------------------------------------------------------------------------------

 

may not surrender that Security for conversion until the Holder has withdrawn
the Fundamental Change Repurchase Notice in accordance with Section 3.04 of this
Supplemental Indenture.
     The first Business Day on which a Holder complies with the relevant
procedures for conversion set forth in clauses (i) through (iv) above and any
other procedures required to effect a conversion under this Indenture shall be
the “Conversion Date” with respect to such Security, and any conversion of a
Security will be deemed to occur at the Close of Business on the Conversion Date
applicable to such Security. If, at any time, the last date on which any
Security may be converted is not a Business Day, such Security may be converted
on the immediately following Business Day.
     (b) Holder of Record If a Holder surrenders the entire principal amount of
a Security for conversion, as of the Close of Business on the applicable
Conversion Date, such Person will no longer be the Holder of such Security. If
any shares of Common Stock are issuable upon the conversion of a Security,
except as provided under Sections 10.05(g) and 10.06(g) hereof, the Person in
whose name such shares of Common Stock will be registered will become the holder
of record of such shares (i) if Physical Settlement applies to such Security, at
the Close of Business on the Conversion Date, and (ii) if Combination Settlement
applies to such Security, at the Close of Business on the last Trading Day of
the applicable Observation Period.
     (c) Conversions in Part. If a Holder surrenders only a portion of the
principal amount of a Definitive Security for conversion, promptly after the
applicable Conversion Date, the Company, in accordance with Section 3.03 of the
Base Indenture, will execute, and the Trustee, in accordance with Section 3.02
of the Base Indenture, will authenticate and deliver to such Holder, one or more
new Definitive Securities, each in an authorized denomination and having an
aggregate principal amount equal to the unconverted portion of the Definitive
Security converted in part. Upon the conversion of any beneficial interest in a
Global Security, the Conversion Agent will promptly request that the Trustee
make a notation on the “Schedule of Increases and Decreases of Global Security”
of such Global Security to reduce the principal amount represented by such
Global Security by the principal amount of the converted beneficial interest.
     (d) Reimbursement of Interest upon Conversion If a Holder converts a
Security after the Close of Business on a Regular Record Date but prior to the
Open of Business on the Interest Payment Date corresponding to such Regular
Record Date, such Holder must accompany such Security with an amount of cash
equal to the amount of interest that will payable on such Security on the
corresponding Interest Payment Date; provided, however, that a Holder need not
make such payment (A) if the Conversion Date follows the Regular Record Date
immediately preceding the Maturity Date; (B) if the Company has specified a
Fundamental Change Repurchase Date that is after a Regular Record Date and on or
prior to the Business Day immediately following the corresponding Interest
Payment Date and the Holder converts its Security after the Close of Business on
such Regular Record Date and on or prior to the Open of Business on such
Interest Payment Date; or (C) to the extent of any overdue interest, if any
overdue interest exists at the time of conversion with respect to such Security.
     (e) Taxes Due upon Conversion If a Holder converts a Security, the Company
will pay any documentary, stamp or similar issue or transfer tax due on the
issue of any shares of the

38

--------------------------------------------------------------------------------

 

Common Stock upon the conversion, unless the tax is due because the Holder
requests that any shares be issued in a name other than the Holder’s name, in
which case the Holder will pay that tax.
Section 10.03 Settlement Upon Conversion
     (a) Settlement Methods Except to the extent otherwise provided in
Sections 10.05(f), 10.05(g), 10.05(h), 10.05(i), 10.06(g) and 10.07 hereof, if a
Holder converts a Security, the Company will satisfy its obligation to convert
the Security (the “Conversion Obligation”) by paying or delivering, as the case
may be, cash (a “Cash Settlement”), shares of Common Stock, together with cash
in lieu of any fractional share of Common Stock (a “Physical Settlement”), or a
combination of cash and shares of Common Stock, together with cash in lieu of
any fractional share of Common Stock (a “Combination Settlement,” and each of
Cash Settlement, Physical Settlement and Combination Settlement, a “Settlement
Method”), based on the Settlement Method that applies to the Security and the
Conversion Rate in effect on the applicable Conversion Date, in each case, as
follows:
          (i) Physical Settlement If Physical Settlement applies to a Security,
the Company will deliver to the Holder of such Security a number of shares of
Common Stock equal to the product of (A)(x) the aggregate principal amount of
such Security that is being converted, divided by (y) $1,000 and (B) the
Conversion Rate in effect on the applicable Conversion Date; provided, however,
that the Company will pay an amount of cash in lieu of any fractional share of
Common Stock determined in accordance with Section 10.03(a)(iv) hereof. The
Company will deliver such shares of Common Stock, and pay any amount of cash in
lieu of any fractional share of Common Stock, on the third Business Day
immediately following the applicable Conversion Date.
          (ii) Cash Settlement If Cash Settlement applies to a Security, the
Company will pay to the Holder of such Security an amount of cash equal to the
product of (A)(x) the aggregate principal amount of such Security that is being
converted, divided by (y) $1,000, and (B) the sum of the Daily Conversion Values
for each of the twenty-five (25) consecutive Trading Days in the applicable
Observation Period. The Company shall pay such amount of cash on the third
Business Day immediately following the last Trading Day of such Observation
Period.
          (iii) Combination Settlement If Combination Settlement applies to a
Security, the Company will pay or deliver, as the case may be, to the Holder of
such Security, the product of (A)(x) the aggregate principal amount of such
Security that is being converted, divided by (y) $1,000, and (B) the sum of the
Daily Settlement Amounts for each of the twenty-five (25) consecutive Trading
Days in the applicable Observation Period; provided, however, that the Company
will pay an amount of cash in lieu of any fractional share of Common Stock
determined in accordance with Section 10.03(a)(iv) below. The Company shall pay
or deliver, as the case may be, such amount of cash and number of shares of
Common Stock on the third Business Day immediately following the last Trading
Day of such Observation Period.
          (iv) Fractional Shares If Physical Settlement or Combination
Settlement applies to a Security and the Company’s Conversion Obligation with
respect to such Security includes a fractional share of Common Stock, in lieu of
delivering such fractional share of

39

--------------------------------------------------------------------------------

 

Common Stock, the Company will pay the converting holder, (A) if Physical
Settlement applies to such Security, an amount of cash equal to the product of
(x) such fraction of a share of Common Stock and (y) the Daily VWAP on the
applicable Conversion Date (or, if such Conversion Date is not a Trading Day,
the immediately preceding Trading Day), and, (B) if Combination Settlement
applies to such Security, an amount of cash equal to the product of (x) such
fraction of a share of Common Stock and (y) the Daily VWAP on the last Trading
Day of the applicable Observation Period.
          (v) Conversion of Multiple Securities by a Single Holder If a Holder
surrenders more than one Security for conversion on a single Conversion Date,
the Company will calculate its Conversion Obligation with respect to such
Securities as if such Holder had surrendered for conversion one Security having
an aggregate principal amount equal to the sum of the principal amounts of each
of the Securities surrendered for conversion by such Holder on such Conversion
Date.
          (vi) Settlement of Accrued Interest and Deemed Payment of Principal
Notwithstanding anything to the contrary in this Indenture, if a Holder converts
a Security, the Company will not adjust the Conversion Rate to account for any
accrued and unpaid interest on such Security and the Company’s payment or
delivery, as the case may be, of the amount of cash, number of shares of Common
Stock, or the amount of cash and the number of shares of Common Stock due as
part of the Company’s Conversion Obligation with respect to such Security will
be deemed to satisfy and discharge in full the Company’s obligation to pay the
principal of the Security and accrued and unpaid interest, if any, on, such
Security to, but excluding the Conversion Date; provided, however, that if a
Holder converts a Security after a Regular Record Date and prior to the Open of
Business on the corresponding Interest Payment Date, the Company will still be
obligated to pay the interest due on such Interest Payment Date to the Holder of
such Security on such Regular Record Date.
     As a result, except as otherwise provided in the proviso to the immediately
preceding sentence, any accrued and unpaid interest with respect to a converted
Security will be deemed to be paid in full rather than cancelled, extinguished
or forfeited. In addition, if the Conversion Obligation for any Security
includes both cash and shares of the Common Stock, accrued and unpaid interest
will be deemed to be paid first out of the amount of cash delivered upon such
conversion.
     (b) Company’s Right to Elect the Settlement Method Except to the extent
otherwise provided in Section 10.06(g) hereof:
          (i) The Company shall use the same Settlement Method to settle every
Security having a given Conversion Date that occurs before the Final Conversion
Period Start Date.
          (ii) The Company shall use the same Settlement Method to settle every
Security having any Conversion Date that occurs on or after the Final Conversion
Period Start Date, regardless of whether such Securities have the same
Conversion Date.

40

--------------------------------------------------------------------------------

 

          (iii) To elect the Settlement Method that will apply to every Security
having a given Conversion Date that occurs before the Final Conversion Period
Start Date, on or prior to the second Scheduled Trading Day immediately
following such Conversion Date, the Company shall deliver, to each Holder
converting a Security on such date, through the Trustee, notice of the
Settlement Method that will apply to every Security converted on such Conversion
Date.
          (iv) To elect the Settlement Method that will apply to every Security
having a Conversion Date on or after the Final Conversion Period Start Date, on
or prior to the Final Conversion Period Start Date, the Company shall deliver,
to each Holder, through the Trustee and a press release, notice of the
Settlement Method that will apply to every Security having a Conversion Date on
or after the Final Conversion Period Start Date.
          (v) Whenever the Company elects to settle Securities with a
Combination Settlement, the notice electing such Settlement Method must also
state the maximum amount of cash that a Holder may receive (for any Combination
Settlement, the “Specified Dollar Amount” for such Combination Settlement) per
$1,000 principal amount of Securities that are subject to such Combination
Settlement.
          (vi) If the Company fails to validly elect a Settlement Method (and
Specified Dollar Amount, if applicable) in accordance with this Section 10.03(b)
that will apply (i) to every Security having a given Conversion Date that occurs
before the Final Conversion Period Start Date or (ii) every Security having a
Conversion Date on or after the Final Conversion Period Start Date, as the case
may be, then Combination Settlement will apply to every Security converted on
such Conversion Date or Conversion Dates, as the case may be, and the Specified
Dollar Amount for such Combination Settlement will equal $1,000.
     (c) Notices Whenever a Conversion Date occurs with respect to a Security,
the Conversion Agent will, as promptly as possible, and in no event later than
the Scheduled Trading Day immediately following such Conversion Date, deliver to
the Company and the Trustee notice that a Conversion Date has occurred, which
notice will state such Conversion Date, the principal amount of Securities
converted on such Conversion Date and the names of the Holders that converted
Securities on such Conversion Date
     On the first Business Day immediately following the last Trading Day of the
Observation Period applicable to any Conversion Date, the Company will deliver
written notice to the Conversion Agent and the Trustee stating (A) the Daily
Settlement Amounts for each Trading Day in such Observation Period, and (B) the
amount of cash, the number of shares of Common Stock, or the amount of cash and
the number of shares of Common Stock, as the case may be, that the Company is
obligated to pay or deliver, as the case may be, to satisfy its conversion
obligation with respect to each Security converted on such Conversion Date.
     (d) Definition Only for the purposes of determining amounts due upon
conversion, “Trading Day” means a day on which (i) there is no Market Disruption
Event and (ii) trading in the Common Stock generally occurs on The NASDAQ Global
Select Market or, if the Common Stock is not then listed on The NASDAQ Global
Select Market, on the primary other United States national or regional
securities exchange on which the Common Stock is then listed or, if the Common
Stock is not then listed on a United States national or regional securities
exchange,

41

--------------------------------------------------------------------------------

 

on the principal other market on which the Common Stock is then listed or
admitted for trading. If the Common Stock is not so listed or admitted for
trading, “Trading Day” means a “Business Day.”
Section 10.04 Certain Covenants Related to Stock Issued Upon Conversion
     (a) To the extent necessary to satisfy its obligations under this
Indenture, prior to issuing any shares of Common Stock, the Company will reserve
out of its authorized but unissued shares or shares held in treasury, the
maximum number of shares of Common Stock potentially required to satisfy
conversion of the Securities from time to time as Securities are presented for
conversion.
     (b) Any shares of Common Stock delivered upon the conversion of the
Securities will be newly issued shares or treasury shares, duly and validly
issued, fully paid, nonassessable, free from preemptive rights and free of any
lien or adverse claim (except to the extent of any lien or adverse claim created
by the action or inaction of the Holder or other Person to whom such shares of
Common Stock will be delivered).
     (c) In addition, 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 authority under any federal or
state law before such shares may be validly issued upon conversion, the Company
will, to the extent then permitted by the rules and interpretations of the
Commission, secure such registration or approval, as the case may be.
     (d) The Company will also use commercially reasonable efforts to cause any
shares of Common Stock issuable upon conversion of a Security to be listed on
whatever stock exchange(s) the Common Stock is listed on the date the converting
Holder becomes a record holder of such Common Stock.
     Section 10.05 Adjustment of Conversion Rate The Company will adjust the
Conversion Rate from time to time as described in this Section 10.05, except
that the Company will not make an adjustment to the Conversion Rate for any
transaction described in this Section 10.05 (other than in the case of a share
split or share combination) if each Holder has the right to participate, in such
transaction at the same time and upon the same terms as holders of the Common
Stock and solely as a result of holding the Securities, without having to
convert its Securities and as if it held a number of shares of the Common Stock
equal to the applicable Conversion Rate, multiplied by the principal amount of
Securities held by such Holder and divided by $1,000.
     (a) Stock Dividends and Share Splits If the Company exclusively issues
shares of Common Stock as a dividend or distribution on all or substantially all
shares of the outstanding Common Stock, or if the Company effects a share split
or share combination of the Common Stock, the Conversion Rate will be adjusted
based on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795801.gif]
     where:

42

--------------------------------------------------------------------------------

 

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Open of
Business on the Ex-Dividend Date of such dividend or distribution, or
immediately prior to the Open of Business on the effective date of such share
split or share combination, as applicable;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Open of Business
on such Ex-Dividend Date or effective date;
 
           
 
  OS0   =   the number of shares of Common Stock outstanding immediately prior
to the Open of Business on such Ex-Dividend Date or such effective date; and
 
           
 
  OS1   =   the number of shares of Common Stock outstanding immediately after
giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this Section 10.05(a) shall become effective
immediately after the Open of Business on the Ex-Dividend Date for such dividend
or distribution, or immediately after the Open of Business on the effective date
for such share split or share combination. If any dividend or distribution of
the type described in this Section 10.05(a) is declared but not so paid or made,
the Conversion Rate shall be immediately readjusted, effective as of the date
the Board of Directors determines not to pay such dividend or distribution to
the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared or announced.
     (b) Rights, Options, and Warrants If the Company issues to all or
substantially all holders of the outstanding Common Stock rights, options or
warrants entitling such holders for a period of not more than 45 calendar days
after the date of such issuance to subscribe for or purchase shares of the
Common Stock at a price per share less than the average of the Last Reported
Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending
on the Trading Day immediately preceding the date of announcement of such
issuance, the Conversion Rate will be increased based on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795802.gif]
     where:

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Open of
Business on the Ex-Dividend Date for such issuance;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Open of Business
on such Ex-Dividend Date;
 
           
 
  OS   =   the number of shares of Common Stock outstanding immediately prior to
the Open of Business on such Ex-Dividend Date;
 
           
 
  X   =   the total number of shares of Common Stock issuable pursuant to such
rights, options or warrants; and

43

--------------------------------------------------------------------------------

 

             
 
  Y   =   the number of shares of Common Stock equal to the aggregate price
payable to exercise such rights, options or warrants divided by the average of
the Last Reported Sale Prices of the Common Stock over the 10 consecutive
Trading Day period ending on the Trading Day immediately preceding the date of
announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 10.05(b) will be made successively whenever
any such rights, options or warrants are issued and shall become effective
immediately after the Open of Business on the Ex-Dividend Date for such
issuance. To the extent that shares of Common Stock are not delivered after the
expiration of such rights, options or warrants, the Conversion Rate shall be
decreased to the Conversion Rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights, options or warrants are not so issued, the Conversion
Rate shall be decreased to such Conversion Rate that would then be in effect if
the Ex-Dividend Date for such issuance had not occurred.
     In determining whether any rights, options or warrants entitle holders of
the Common Stock to subscribe for or purchase shares of the Common Stock at a
price per share less than the average of the Last Reported Sale Prices for
Common Stock over the 10 consecutive Trading Day period ending on the Trading
Day immediately preceding the date of announcement for an issuance 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, options 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) Spin-Offs and Other Distributed Property
     (i) If the Company distributes shares of the Capital Stock of the Company,
evidences of its indebtedness, other assets or property of the Company or
rights, options or warrants to acquire the Company’s Capital Stock or other
securities of the Company to all or substantially all holders of Common Stock,
excluding:
     (A) dividends, distributions, rights, options or warrants as to which an
adjustment was effected pursuant to Section 10.05(a) hereof or Section 10.05(b)
hereof;
     (B) dividends or distributions paid exclusively in cash as to which an
adjustment was effected pursuant to Section 10.05(d) hereof; and
     (C) Spin-Offs as to which the provisions of Section 10.05(c)(ii) hereof
shall apply,
then the Conversion Rate will be increased based on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795803.gif]

44

--------------------------------------------------------------------------------

 

    where:

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Open of
Business on the Ex-Dividend Date for such distribution;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Open of Business
on such Ex-Dividend Date;
 
           
 
  SP0   =   the average of the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period ending on the Trading Day immediately
preceding the Ex-Dividend Date for such distribution; and
 
           
 
  FMV   =   the fair market value (as determined by the Board of Directors) of
the shares of Capital Stock, evidences of indebtedness, other assets, or
property of the Company or rights, options or warrants to acquire the Company’s
Capital Stock or other securities distributed with respect to each outstanding
share of Common Stock on the Ex-Dividend Date for such distribution.

If “FMV” (as defined above) is equal to or greater than the “SP0” (as defined
above), in lieu of the foregoing increase, each Holder of Securities will
receive, in respect of each $1,000 principal amount of Securities it holds, at
the same time and upon the same terms as holders of the Common Stock, the amount
and kind of shares of the Company’s Capital Stock, evidences of indebtedness,
other assets or property of the Company or rights, options or warrants to
acquire the Company’s Capital Stock or other securities that such Holder would
have received if such Holder had owned a number of shares of the Common Stock
equal to the Conversion Rate in effect on the Ex-Dividend Date for the
distribution.
     Any increase in the Conversion Rate made under this Section 10.05(c)(i)
will become effective immediately after the Open of Business on the Ex-Dividend
Date for such distribution. If such distribution is not so paid or made, the
Conversion Rate shall be decreased to be the Conversion Rate that would then be
in effect if such dividend or distribution had not been declared.
          (ii) With respect to an adjustment pursuant to this Section 10.05(c)
where there has been a payment of a dividend or other distribution on the Common
Stock of shares of Capital Stock of any class or series, or similar equity
interest, of or relating to an Affiliate or other business unit of the Company,
and such Capital Stock or similar equity interest is listed or quoted (or will
be listed or quoted upon the consummation of such dividend or other
distribution) on a national securities exchange or a reasonably comparable
non-U.S. equivalent (a “Spin-Off”), the Conversion Rate will be increased based
on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795804.gif]

45

--------------------------------------------------------------------------------

 

    where:

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Open of
Business on the Ex-Dividend Date for the Spin-Off;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Open of Business
on the Ex-Dividend Date for the Spin-Off;
 
           
 
  FMV0   =   the average of the Last Reported Sale Prices of the Capital Stock
or similar equity interest distributed to holders of Common Stock applicable to
one share of the Common Stock over the first 10 consecutive Trading Day period
after, and including, the effective date of the Spin-Off (the “Valuation
Period”); and
 
           
 
  MP0   =   the average of the Last Reported Sale Prices of the Common Stock
over the Valuation Period.

If a Holder converts a Security, Cash Settlement or Combination Settlement
applies to such Security, and the first Trading Day of the Observation Period
applicable to such Security occurs after the first Trading Day of the Valuation
Period for a Spin-Off, but on or before the last Trading Day of the Valuation
Period for such Spin-Off, the reference in the above definition of “FMV” to “10”
shall be deemed replaced with such lesser number of Trading Days as have elapsed
from, and including, the effective date of such Spin-Off to, but excluding, the
first Trading Day of such Observation Period. If a Holder converts a Security,
Cash Settlement or Combination Settlement applies to the Conversion Date
applicable to such Security, and one or more Trading Days of the Observation
Period applicable to such Security occurs on or after the Ex-Dividend Date for a
Spin-Off, but on or prior to the first Trading Day of the Valuation Period for
such Spin-Off, such Observation Period will be suspended on the first such
Trading Day and will resume immediately after the first Trading Day of the
Valuation Period for such Spin-Off, and the reference in the above definition of
“FMV” to “10” shall be deemed replaced with a reference to “one” (1) .
     For purposes of this Section 10.05(c)(ii), the Last Reported Sale Price of
any Capital Stock or similar equity interest shall be calculated in a manner
analogous to that used to calculate the Last Reported Sale Price of the Common
Stock in the definition of “Last Reported Sale Price” set forth in Section 1.01
hereof.
     For purposes of Section 10.05(a) hereof, Section 10.05(b) hereof and this
Section 10.05(c), if any dividend or distribution to which this Section 10.05(c)
applies includes one or both of:
     (A) a dividend or distribution of shares of Common Stock to which
Section 10.05(a) hereof also applies (the “Clause A Distribution”); or
     (B) a dividend or distribution of rights, options or warrants to which
Section 10.05(b) hereof also applies (the “Clause B Distribution”),

46

--------------------------------------------------------------------------------

 

then (i) such dividend or distribution, other than the Clause A Distribution and
the Clause B Distribution, shall be deemed to be a dividend or distribution to
which this Section 10.05(c) applies (the “Clause C Distribution”) and any
Conversion Rate adjustment required to be made under this Section 10.05(c) with
respect to such Clause C Distribution shall be made, (ii) the Clause B
Distribution, if any, shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 10.05(b)
hereof with respect thereto shall then be made, except that, if determined by
the Company, (A) the “Ex-Dividend Date” of the Clause B Distribution and the
Clause A Distribution, if any, shall be deemed to be the Ex-Dividend Date of the
Clause C Distribution and (B) any shares of Common Stock included in the Clause
A Distribution or the Clause B Distribution shall not be deemed to be to be
“outstanding immediately prior to the Open of Business on such Ex-Dividend Date”
within the meaning of Section 10.05(b) hereof, and (iii) the Clause A
Distribution, if any, shall be deemed to immediately follow the Clause C
Distribution or the Clause B Distribution, as the case may be, except that, if
determined by the Company, (A) the “Ex-Dividend Date” of the Clause A
Distribution and the Clause B Distribution, if any, shall be deemed to be the
Ex-Dividend Date of the Clause C Distribution, and any shares of Common Stock
included in the Clause A distribution shall not be deemed to be “outstanding
immediately prior to the Open of Business on such Ex-Dividend Date or such
effective date” within the meaning of Section 10.05(a) hereof.
     (d) Cash Dividends or Distributions If any cash dividend or distribution is
made to all or substantially all holders of the Common Stock, the Conversion
Rate will be adjusted based on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795805.gif]
     where:

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Open of
Business on the Ex-Dividend Date for such dividend or distribution;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Open of Business
on the Ex-Dividend Date for such dividend or distribution;
 
           
 
  SP0   =   the Last Reported Sale Price of the Common Stock on the Trading Day
immediately preceding the Ex-Dividend Date for such dividend or distribution;
and
 
           
 
  C   =   the amount in cash per share the Company distributes to holders of the
Common Stock.

If “C” (as defined above) is equal to or greater than “SP” (as defined above),
in lieu of the foregoing increase, each Holder shall receive, for each $1,000
principal amount of Securities it holds, at the same time and upon the same
terms as holders of the Common Stock the amount of cash that such Holder would
have received if such Holder had owned a number of shares of the Common Stock
equal to the Conversion Rate on the Ex-Dividend Date. Any increase made under
this Section 10.05(d) shall become effective immediately after the Open of
Business on the

47

--------------------------------------------------------------------------------

 

Ex-Dividend Date for such dividend or distribution. If such dividend or
distribution is not so paid, the Conversion Rate shall be decreased to be the
Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.
     (e) Tender Offers or Exchange Offers If the Company or any of its
Subsidiaries makes a payment in respect of a tender offer or exchange offer for
the Common Stock, to the extent that the cash and value of any other
consideration included in the payment per share of the Common Stock exceeds the
Last Reported Sale Price of the Common Stock on the Trading Day next succeeding
the last date on which tenders or exchanges may be made pursuant to such tender
offer or exchange offer (the “Expiration Date”), the Conversion Rate will be
increased based on the following formula:
(MATHEMATICAL EQUATION) [v57958v5795806.gif]
     where:

             
 
  CR0   =   the Conversion Rate in effect immediately prior to the Close of
Business on the Expiration Date;
 
           
 
  CR1   =   the Conversion Rate in effect immediately after the Close of
Business on the Expiration Date;
 
           
 
  AC   =   the aggregate value of all cash and any other consideration (as
determined by the Board of Directors) paid or payable for shares purchased in
such tender or exchange offer;
 
           
 
  OS0   =   the number of shares of Common Stock outstanding immediately prior
to the Close of Business on the Expiration Date (prior to giving effect to the
purchase of all shares accepted for purchase or exchange in such tender or
exchange offer);
 
           
 
  OS1   =   the number of shares of Common Stock outstanding immediately after
the Close of Business on the Expiration Date (after giving effect to the
purchase of all shares accepted for purchase or exchange in such tender or
exchange offer); and
 
           
 
  SP1   =   the average of the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period commencing on the Trading Day next
succeeding the Expiration Date (the “Averaging Period”).

If a Holder converts a Security, Cash Settlement or Combination Settlement
applies to such Security, and the first Trading Day of the Observation Period
applicable to such Security occurs after the first Trading Day of the Averaging
Period for any tender or exchange offer, but on or before the last Trading Day
of the Averaging Period for such tender or exchange offer, the reference in the
above definition of “SP1” to “10” shall be deemed replaced with such lesser
number of Trading Days as have elapsed from, and including, the first Trading
Day of the

48

--------------------------------------------------------------------------------

 

Averaging Period for such tender or exchange offer to, but excluding, the first
Trading Day of such Observation Period. If a Holder converts a Security, Cash
Settlement or Combination Settlement applies to such Security, and one or more
Trading Days of the Observation Period for such Security occurs on or after the
Expiration Date for any tender or exchange offer, but on or prior to the first
Trading Day in the Averaging Period for a tender or exchange offer, such
Observation Period will be suspended on the first such Trading Day and will
resume immediately after the first Trading Day of the Averaging Period for such
tender or exchange offer and the reference in the above definition of “SP” to
“10” shall be deemed replaced with a reference to “one” (1).
     If 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 be decreased to the Conversion Rate that would then be in
effect if such tender or exchange offer had not been made or had been made only
in respect of the purchases that actually were effective.
     (f) Special Provisions for the Physical Settlement of Certain Conversions
Notwithstanding anything to the contrary in Sections 10.05(a) through 10.05(e)
hereof, if (i) the Ex-Dividend Date occurs for any event that, pursuant to any
of Sections 10.05(a) through 10.05(e) hereof would require that an adjustment be
made to the Conversion Rate to account for such event on such Ex-Dividend Date,
(ii) a Holder converts a Security on or after such Ex-Dividend Date and on or
prior to the record date for such event, (iii) Physical Settlement applies to
such Security, and (iv) as a result of such conversion, such Holder, but for
this Section 10.05(f), would be entitled to receive a shares of Common Stock as
part of a Conversion Obligation calculated based on a Conversion Rate adjusted
to account for such event and would be treated as the record holder of such
shares of Common Stock on the applicable Conversion Date (and therefore be
entitled to participate in such event on account of such shares of Common
Stock), then (i) the Company will not increase the Conversion Rate for such
Holder pursuant to such clause of this Section 10.05 as a result of such event
and (ii) shall instead treat such Holder as entitled to participate in the event
that, but for this Section 10.05(f), would have given rise to such adjustment,
on account of such shares of Common Stock.
     (g) Special Provisions for Combination Settlement of Certain Conversions
Notwithstanding anything to the contrary herein:
          (i) If a Holder converts a Security and (A) Combination Settlement
applies to such Security and (B) the Daily Settlement Amount for any Trading Day
during the applicable Observation Period (x) is calculated based on a Conversion
Rate adjusted on account of any event described in clauses (a) through (e) of
this Section 10.05; and (y) includes any shares of Common Stock that, but for
this provision, would entitle their Holder to participate in such event, then,
although the Company will treat such Holder as the holder of record of such
shares of Common Stock on the last Trading Day of such Observation Period, the
Company will not permit such Holder to participate in such event on account of
such shares of Common Stock.
          (ii) If a Holder converts a Security and (A) Combination Settlement
applies to such Security, (B) the record date, effective date or expiration date
for any event that requires an adjustment to the Conversion Rate under any of
clauses (a) through (e) of this Section 10.05

49

--------------------------------------------------------------------------------

 

occurs (x) on or after the first trading day of the applicable Observation
Period, and (y) on or prior to the last trading day of such Observation Period;
and (C) the Daily Settlement Amount for any trading day in such Observation
Period that occurs on or prior to such record date, effective date or expiration
date (x) includes shares of the Common Stock that do not entitle their holder to
participate in such event; and (y) is calculated based on a Conversion Rate that
is not adjusted on account of such event, then, on account of such conversion,
the Company will, on such record date, effective date or expiration date, as the
case may be, treat such Holder, as a result of having converted such Securities,
as though it were the holder of record of a number of shares of Common Stock
equal to the total number of shares of Common Stock that (A) are deliverable as
part of the Daily Settlement Amount (x) for a Trading Day in such Observation
Period that occurs on or prior to such record date, effective date or expiration
date; and (y) is calculated based on a Conversion Rate that is not adjusted for
such event; and (B) but for this provision, would not entitle such Holder to
participate in such event.
     (h) Rights Plan To the extent that the Company’s existing rights plan or
any future rights plan is in effect, if Physical Settlement applies to a
Security converted by a Holder, on the applicable Conversion Date, and if
Combination Settlement applies to a Security converted by a Holder, on any
Trading Day in the Observation Period applicable to such Security, the
converting Holder will receive, in addition to any shares of Common Stock that
it would otherwise receive as part of, if Physical Settlement applies, the
Conversion Obligation calculated on such Conversion Date, and if Combination
Settlement applies, the Daily Settlement Amount for such Trading Day, the rights
under such rights plan, unless prior to such Conversion Date or Trading Day, as
the case may be, the rights have separated from the Common Stock, in which case,
and only in such case, the Conversion Rate will be adjusted at the time of
separation as if the Company distributed, to all holders of the Common Stock,
shares of the Capital Stock, evidences of indebtedness, other assets or property
of the Company or rights, options or warrants to acquire Capital Stock of the
Company or other securities as described in clause (c) of this Section 10.05,
subject to readjustment in the event of the expiration, termination or
redemption of such rights.
     (i) Other Adjustments Whenever a provision of this Indenture requires the
calculation of the Last Reported Sale Prices, the Daily VWAPs, the Daily
Conversion Values, the Daily Settlement Amounts, the Last Reported Sale Prices
or any functions thereof over a span of multiple days (including, without
limitation, during an Observation Period and during the 10 Trading Day period
used to determine the Stock Price for a Fundamental Change), the Company will
make appropriate adjustments to each to account for any event requiring an
adjustment to the Conversion Rate where the Ex-Dividend Date, effective date or
Expiration Date of the event occurs at any time during the period in which the
Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values, the
Daily Settlement Amounts, or functions thereof are to be calculated.
     (j) Successive Adjustments After an adjustment to the Conversion Rate under
this Article 10, any subsequent event requiring an adjustment under this
Article 10 will cause an adjustment to the Conversion Rate as so adjusted,
without duplication.
     (k) Limitations on Adjustments

--------------------------------------------------------------------------------

 

          (i) Except as stated in this Article X, the Company will not adjust

of Common Stock (or rights to acquire shares of Common Stock) or from any event
treated as such for U.S. federal income tax purposes.

required to file with the Commission a Schedule TO in connection with such
tender or exchange offer, an additional notice (i) when the Company first files
such Schedule TO, which notice shall include the address at which such
Schedule TO is available on EDGAR (or any successor thereto), and, (ii) whenever
the Company files an amendment to such Schedule TO, which notice shall include
the address at which such amendment is available on EDGAR (or any successor
thereto).
               (C) Voluntary Increases If the Company increases the Conversion

date on which such dissolution, liquidation or winding-up, as the case may be,
is expected to become effective or occur, and (ii) 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
dissolution, liquidation or winding-up, as the case may be, which notice shall
state the expected effective date and record date for such event, as applicable,
and the amount and kind of property that a holder of one share of the Common
Stock is expected to be entitled, or may elect, to receive in such event. The
Company shall deliver an additional notice to holders, as promptly as

or the amount and kind of property that a holder of one share of the Common
Stock is expect to be entitled to receive in such event, changes.
     (ii) Notices After Certain Actions and Events Whenever an adjustment to the
Conversion Rate becomes effective pursuant to Section 10.05 hereof, the Company
will (i) file with the Trustee an Officers’ Certificate stating that such
adjustment has become effective, the Conversion Rate, and the manner in which
the adjustment was computed and (ii) deliver notice to the Holder’s stating that
such adjustment has become effective and the Conversion Rate or conversion
privilege as adjusted. Failure to give any such notice, or any defect therein,
shall not affect the validity of any such adjustment.
     Section 10.06 Adjustments to Conversion Rate upon Conversion In Connection
With a Make-Whole Fundamental Change
     (a) General If a Fundamental Change occurs and a Holder elects to convert
its Securities “in connection with” such Fundamental Change, the Company will,
in the circumstances described in this Section 10.06, increase the Conversion
Rate applicable to the Securities so surrendered for conversion by a number of
additional shares of Common Stock (the “Additional Shares”) as set forth n this
Section 10.06. For purposes of this Section 10.06, a conversion of Securities
will be deemed to be “in connection with” a Fundamental Change if the Conversion
Notice for such Securities is received by the Conversion Agent during the period
from, and including, the day that is 10 days prior to the anticipated effective
date of such Fundamental Change (the “Fundamental Change Effective Date”) up to,
and including, the Close of Business on the Business Day immediately preceding
the Fundamental Change Repurchase Date for such Fundamental Change.
(b) Notices
          (i) Notice of an Anticipated Fundamental Change The Company will
notify the Holders of any Fundamental Change and the anticipated Fundamental
Change Effective Date for such Fundamental Change as promptly as practicable
following the date on which the Company publicly announces such Fundamental
Change, but in no event less than 35 Scheduled Trading Days prior to the
anticipated Fundamental Change Effective Date for such Fundamental

53

--------------------------------------------------------------------------------

 

Change; provided that if the Company does not have knowledge of a Fundamental
Change or the anticipated Fundamental Change Effective Date for such Fundamental
Change at least 35 Scheduled Trading Days prior to the anticipated Fundamental
Change Effective Date for such Fundamental Change, the Company will notify the
Holders of the Fundamental Change within one Business Day of the date upon which
it receives notice, or otherwise become aware, of the Fundamental Change and the
anticipated Fundamental Change Effective Date for such Fundamental Change, but
in no event later than the actual Fundamental Change Effective Date for such
Fundamental Change.
          (ii) Additional Notices If the Company has previously notified the
Holders of a Fundamental Change and the anticipated Fundamental Change Effective
Date for such Fundamental Change, the Company will deliver updated notice to the
Holders within one business day of (i) any change in the anticipated Fundamental
Change Effective Date for such Fundamental Change, (ii) the occurrence of the
Fundamental Change Effective Date, and (iii) the Company’s determination that
the Fundamental Change will not take place, as applicable.
     (c) Determination of Additional Shares The number of Additional Shares, if
any, by which the Conversion Rate will be increased if a Holder converts a
Security “in connection with” a Fundamental Change will be determined by
reference to the table below and will be based on the Fundamental Change
Effective Date and the Stock Price for such Fundamental Change.
     (d) Adjustment of Stock Prices and Additional Shares The Stock Prices set
forth in the column headings of the table below will be adjusted as of any date
on which the Conversion Rate of the Securities is otherwise required to be
adjusted pursuant to Section 10.05 hereof. The adjusted Stock Prices in the
table below will equal the Stock Prices in effect immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate in effect immediately prior to the adjustment giving rise to the adjustment
to the Stock Price and the denominator of which is the Conversion Rate in effect
immediately after such adjustment. The numbers of Additional Shares set forth in
the table below will be adjusted in the same manner, at the same time and on
account of the same events for which the Conversion Rate must be adjusted as set
forth in Section 10.05 hereof.
     (e) Additional Shares Table The following table sets forth the number of
Additional Shares by which the Conversion Rate will be increased for a
Fundamental Change having the Stock Price and the Fundamental Change Effective
Date set forth below:

     (f) Use of Additional Shares Table If the Stock Price and/or Fundamental
Change Effective Date for a Fundamental Change are not set forth in the table
above, then:
          (i) if the Stock Price is between two Stock Prices in the table or the
Fundamental Change Effective Date is between two Fundamental Change Effective
Dates in the table, the number of Additional Shares will be determined by a
straight-line interpolation between the numbers of Additional Shares set forth
in the table for the higher and lower Stock Prices and the earlier and later
Fundamental Change Effective Dates, as applicable, based on a 365-day year;
          (ii) if the Stock Price is greater than $130.00 per share, subject to
adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above, no additional shares will be added to the
Conversion Rate; and
          (iii) if the Stock Price is less than $36.60 per share, subject to
adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above, no additional shares will be added to the
Conversion Rate.
Notwithstanding the foregoing, in no event will the Conversion Rate, as
increased pursuant to this Section 10.06 by the number of Additional Shares,
exceed 27.3224 shares of Common Stock per $1,000 principal amount of Securities,
subject to adjustments in the same manner, at the same time and on account of
the same events for which the Conversion Rate is required to be adjusted as set
forth in Section 10.05 hereof.
     (g) Settlement of Conversions “In Connection With” a Fundamental Change If
a Holder converts a Security “in connection with” a Fundamental Change, the
Company will settle the conversion in accordance with Section 10.03 hereof;
provided, however, that notwithstanding anything to the contrary in
Section 10.03 hereof, if a Holder converts a Security “in connection with” a
Fundamental Change and such Fundamental Change is a Cash Merger, the Company
will satisfy its Conversion Obligation with respect to such Security by paying
to the converting Holder, on the third Business Day immediately following the
applicable Conversion Date, in lieu of any cash, shares of the Common Stock, or
combination of cash and shares of the Common Stock that it would otherwise be
obligated to pay or deliver, as the case may be, to such Holder pursuant to
Section 10.03, an amount of cash equal to the product of (i) the Conversion Rate
in effect on the applicable Conversion Date (including any adjustment that the
Company is required to make pursuant to this Section 10.06), multiplied by the
Stock Price for such Fundamental Change; and provided, further, that
notwithstanding anything to the contrary in Section 10.03 of this Supplemental
Indenture or the immediately preceding proviso to this section 10.06(g), if a
Holder converts a Security “in connection with” a Fundamental Change and:

55

--------------------------------------------------------------------------------

 

          (i) (A)(1) Physical Settlement applies to the applicable Conversion
Date or (2) such Fundamental Change is a Cash Merger and (B) the applicable
Conversion Date occurs on or before the Fundamental Change Effective Date for
such Fundamental Change; or
          (ii) (A) Cash Settlement or Combination Settlement applies to the
applicable Conversion Date, (B) such Fundamental Change is not a Cash Merger and
(C) the first day of the applicable Observation Period occurs on or before the
Fundamental Change Effective Date for such Fundamental Change,
then, in each case,
          (iii) the Company will settle its Conversion Obligation with respect
to such Security as provided in either Section 10.03 hereof or the immediately
preceding proviso to this Section 10.06(g) except that the Conversion Rate used
to determine such Settlement Obligation will not include the Additional Shares;
and
          (iv) if such Fundamental Change becomes effective, the Company will
satisfy the remainder of its Conversion Obligation as if (A) the Conversion Date
applicable to such Security were the Fundamental Change Effective Date for such
Fundamental Change, (B) the Conversion Rate in effect on such Fundamental Change
Effective Date equaled the number of Additional Shares for such Fundamental
Change, and (C) if such Fundamental Change is not a Cash Merger, the Company
elected (or was deemed to elect) that the Settlement Method applicable to such
deemed Conversion Date is the same Settlement Method that was applicable to the
actual Conversion Date for the Security, notwithstanding any election or deemed
election by the Company with respect to such deemed Settlement Date to the
contrary; or
          (v) if such Fundamental Change fails to become effective the Company
will have no obligation to deliver any additional consideration under this
Section 10.06 to satisfy its Conversion Obligation with respect to such Security
with respect to any Additional Shares.
     Section 10.07 Effect of Recapitalization, Reclassification, Consolidation,
Merger or Sale
     (a) In General If any of the following events occur:
          (i) any recapitalization, reclassification or change of the Common
Stock (other than changes resulting from a subdivision or combination or change
in par value);
          (ii) any consolidation, merger or combination involving the Company;
          (iii) any sale, lease or other transfer to a third party of the
consolidated assets of the Company and its Subsidiaries substantially as an
entirety; or
          (iv) any statutory share exchange;
and, in each case, as a result of such event, the Common Stock would be
converted into, or exchanged for, stock, other securities, other property or
assets (including cash or any combination thereof) (each such event, a “Merger
Event,” such stock, other securities, other property or assets (including cash
or any combination thereof), “Reference Property,” and the

56

--------------------------------------------------------------------------------

 

amount and kind of Reference Property that a holder of one share of Common Stock
is entitled to receive in such Merger Event, or if in such Merger Event the
holders of the Common Stock are entitled to elect to convert their shares of
Common Stock into, or exchange their shares of Common Stock for, the right to
receive more than a single type of consideration, the weighted per-share of
common Stock average of the types and amounts of consideration received by the
holders of Common Stock that affirmatively make such an election, a “Unit of
Reference Property”), then at and after the effective time of Merger Event, the
right to convert each $1,000 principal amount of Securities based on a number of
shares of the Common Stock equal to the applicable Conversion Rate will be
changed into the right to convert each $1,000 principal amount of Securities
into based on a number of Units of Reference Property equal to the applicable
Conversion Rate. In particular, prior to the effective date of the Merger Event,
the Company or the successor or purchasing Person, as the case may be, will
execute with the Trustee a supplemental indenture pursuant to Section 9.02
hereof, that will not adversely affect the rights of any Holder and that will
provide that, at and after the effective time of the Merger Event:
     (A) the Company will continue to have the right to choose the Settlement
Method applicable to any converted Securities to the extent otherwise provided
in Section 10.03 hereof;
     (B) any amount of cash that the Company would otherwise be required to pay
pursuant to Sections 10.03, 10.05 and 10.06 as part of the Conversion Obligation
with respect to a Security will continue to be payable in cash;
     (C) any number of shares of the Common Stock that the Company would
otherwise be required to deliver pursuant to Sections 10.03, 10.05 and 10.06
hereof as part the Conversion Obligation with respect to a Security will instead
be deliverable in Units of Reference Property;
     (D) the Daily VWAP and the Last Reported Sale Price will be calculated
based on the value of a Unit of Reference Property; and
     (E) the Conversion Rate shall be subject to adjustments that the Board of
Directors determines are as nearly equivalent as possible to the adjustments
provided for in Article 10 hereof.
     (b) If, for any Merger Event, the Reference Property includes shares of
stock, securities or other property or assets (including cash or any combination
thereof) of a Person other than the successor or purchasing corporation, as the
case may be, in such Merger Event, then such supplemental indenture shall also
be executed by such other Person 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.
     (c) Notices If the Company or any successor or purchasing Person or other
Person executes a supplemental indenture pursuant to Section 10.07(a) hereof and
10.07(b) hereof, as applicable, then the Company or such successor or purchasing
Person or other Person, as applicable, shall promptly file with the Trustee an
Officers’ Certificate briefly stating the reasons

57

--------------------------------------------------------------------------------

 

therefore, the kind or amount of cash, securities or property or assets that
will comprise a Unit of Reference Property after the applicable Merger Event,
any adjustment to be made with respect thereto and that all relevant conditions
precedent have been complied with, and shall promptly mail notice thereof to all
Holders. If, at the time such a supplemental indenture is executed, the Company
cannot calculate the composition of a Unit of Reference Property because it is
subject to a shareholder election, the Company may deliver notice of the kind or
amount of cash, securities or property or assets that will comprise a Unit of
Reference Property after the Merger Event as promptly as practicable after it is
able to make such calculation. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.
     (d) The above provisions of this Section 10.07 shall similarly apply to
successive recapitalizations, reclassifications, mergers, consolidations,
statutory share exchanges, combinations, sales and conveyances.
     Section 10.08 No Responsibility of Trustee. The Trustee and the Conversion
Agent will not have any duty or responsibility to any Holder to determine
whether any facts exist that require an 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 in making the same. Neither the
Trustee nor the Conversion Agent will be responsible for any failure of the
Company to deliver any amount of cash or number of shares of Common Stock upon
the surrender of any Securities 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 the Conversion Agent will be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 10.07 hereof, including with respect to the
calculation of the amount of cash, the number of Units of Reference Property, or
the combination of cash and Units of Reference Property receivable by Holders
upon the conversion of their Securities after any Merger Event, and each,
subject to the provisions of Article 6 of the Base Indenture in the case of the
Trustee, may accept as conclusive evidence of the correctness of any such
provisions, and will be protected in relying upon, the Officers’ Certificate
(which the Company will be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.

or the Conversion Agent, as the case may be, and each of the Trustee and
Conversion Agent will be entitled to rely conclusively upon the accuracy of any
calculations contained in such a schedule without independent verification. If
any Holder requests a copy of such a schedule from the Trustee, the Trustee will
request such a schedule from the Company and, upon receipt of such a schedule,

[FORM OF REVERSE OF SECURITY]
DENDREON CORPORATION
2.875% Convertible Senior Notes due 2016
     This Security is one of a duly authorized issue of Securities of Dendreon
Corporation (the “Company”), designated as its 2.875% Convertible Senior Notes
due 2016 (the “Securities”), all issued or to be issued under and pursuant to an
indenture dated as of March 16, 2007 (the “Base Indenture”), as supplemented by
the First Supplemental Indenture dated as of January 20, 2011 (the “Supplemental
Indenture,” and the Base Indenture, as supplemented by the Supplemental
Indenture, and as it may be further amended or supplemented from time to time,
the “Indenture”), between the Company and The Bank of New York Mellon Trust
Company, N.A. (the “Trustee”), and reference is made herby to the Indenture for
a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders and of the
terms upon which the Securities are, and will be, authenticated and delivered.
     As provided in and subject to the provisions of the Indenture, upon the
occurrence of a Fundamental Change, the Holder of this Security will have the
right, at such Holder’s option, to require the Company to repurchase this
Security, or any portion of this Security such that the principal amount of this
Security that is not repurchased equals $2,000 or an integral multiple of $1,000
in excess thereof, on the Fundamental Change Repurchase Date at a price equal to
the Fundamental Change Repurchase Price for such Fundamental Change Repurchase
Date.
     This Security is not subject to redemption at the option of the Company and
does not benefit from a sinking fund.
     As provided in and subject to the provisions of the Indenture, the Holder
of this Security has the right, at its option, at any time prior to the Close of
Business on the second Scheduled Trading Day immediately preceding the Maturity
Date, to convert this Security or a portion of this Security such that the
principal amount of this Security that is not converted equals $2,000 or an
integral multiple of $1,000 in excess thereof, into an amount of cash, a number
of shares of Common Stock, or a combination of cash and shares of Common Stock,
in each case, determined in accordance with Article 10 of the Supplemental
Indenture.
     As provided in and subject to the provisions of the Indenture, the Company
will make all payments in respect of the Fundamental Change Purchase Price for,
and the principal amount of, this Security to the Holder that surrenders this
Security to the Paying Agent to collect such payments in respect of this
Security. The Company will 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.
     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities to be effected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of then Outstanding Securities, on
behalf of the Holders of all

Securities, to waive compliance by the Company with certain provisions of the
Indenture and certain past Defaults and Events of Default under the Indenture
and their consequences. Without the consent of or notice to any Holder, the
Company and the Trustee may amend or supplement the Indenture or the Securities
to, among other things, cure any ambiguity, defect or inconsistency or make any
other change that does not adversely affect the rights under the Indenture of
any Holder of Outstanding Securities. Any such amendment, consent or waiver by
the Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such amendment, consent or waiver is made upon this
Security.
     As provided in and subject to the provisions of the Indenture, in case
certain Events of Default, as defined in the Indenture, shall have occurred and
be continuing, the principal of, and the interest on, all Securities may be
declared due and payable by either the Trustee or Holders of at least 25% in
aggregate principal amount of then Outstanding Securities, and upon said
declaration shall become due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture. In the case of certain
insolvency events relating to the Company or any Significant Subsidiary of the
Company, the principal of, and interest on, all Securities will immediately
become due and payable.
     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Register, upon
surrender of this Security for registration of transfer at the office or agency
of the Company in any place where the principal of and interest on this Security
are payable, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar duly executed by,
the Holder hereof or its attorney duly authorized in writing, and thereupon one
or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.
     The Securities are issuable only in registered form without coupons in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
the Securities are exchangeable for a like aggregate principal amount of
Securities and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.
     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or Trustee may treat the
Person in whose name the Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.
     All defined terms used in this Security that are defined in the Indenture
shall have the meanings assigned to them in the Indenture. If any provision of
this Security limits, qualifies or conflicts with a provision of the Indenture,
such provision of the Indenture shall control.
