RESTRICTED STOCK UNIT AGREEMENT

PURSUANT TO THE

MARKETAXESS HOLDINGS INC. 2004 STOCK INCENTIVE PLAN

(AMENDED AND RESTATED EFFECTIVE APRIL 28, 2006)

THIS RESTRICTED
STOCK UNIT AGREEMENT (this “Agreement”), is dated January 19, 2011
(the “Grant Date”) by and between MarketAxess Holdings Inc. (the “Company”) and you
(the “Participant”).

WHEREAS, the Board of Directors of the Company (the “Board”) adopted The MarketAxess
Holdings Inc. 2004 Stock Incentive Plan (Amended and Restated Effective April 28, 2006) (the
“Plan”) which is administered by a Committee appointed by the Company’s Board of Directors
(the “Committee”);

WHEREAS, pursuant to Section 3.3 of the Plan, the Committee has adopted guidelines (the
“Guidelines”) for the grant of restricted stock units (“RSUs”) under the Plan, which constitute an
Other Stock-Based Award under the Plan; and

WHEREAS, the Company, through the Committee, wishes to grant to the Participant RSUs as set forth
below.

NOW, THEREFORE, the Company and the Participant agree as follows:

	1.	 	Grant of RSUs. Subject to the terms and conditions of the Plan, the Guidelines and
this Agreement, on the Grant Date the Company awarded to the
Participant 59,782 RSUs. The RSUs
hereunder are not Deferrable RSUs and are not eligible for deferral under Section 4 of the
Guidelines.
	 
	2.	 	Vesting.

	 	2.1	 	Except as set forth in this Section 2, and notwithstanding anything in the Guidelines
to the contrary (including without limitation Section 3.1 of the Guidelines), the RSUs
shall become vested (but shall remain subject to Section 3 of this Agreement) pursuant to
the following schedule, provided that the Participant has not had a Termination from the
date of grant until the applicable vesting date:

	 	 	 	 	 
	 	 	Incremental Percentage of RSUs	 
	Vesting Date	 	Vested	 
	January 15, 2012
	 	 	12.5	%
	January 15, 2013
	 	 	25.0	%
	January 15, 2014
	 	 	25.0	%
	January 15, 2015
	 	 	25.0	%
	January 15, 2016
	 	 	12.5	%

	 	2.2	 	Notwithstanding Section 2.1 of this Agreement and anything in the Guidelines to the
contrary (including without limitation Sections 3.3 and 3.4(iv) of the Guidelines):

(a) upon the Participant’s death or Disability 50% of any RSUs that are unvested on
the date of the Participant’s death or Disability, as applicable, shall become immediately
vested; and

 

 

 

(b) upon the Participant’s Termination (x) by the Company without Cause, or (y) by the
Participant for Good Reason, any portion of the RSUs that would
have otherwise become vested in (x) the twelve (12) month period following the
date of such Termination if such Termination occurs outside of a Change in
Control Period or (y) the twenty-four (24) month period following the date of
such Termination if such Termination occurs during a Change in Control Period,
shall become immediately vested on the date of such Termination.

“Change in Control Period” means the three (3) month period prior to, and the eighteen
month period following, a Change in Control that constitutes a Change in Control Event
within the meaning of Section 409A of the Code.

	 	2.3	 	Notwithstanding anything herein to the contrary, in the event of the Participant’s
Termination as a result of the Company’s non-extension of the letter agreement between the
Company and the Participant, dated January 19, 2011, in accordance with the terms thereof,
the then unvested portion of the RSUs shall continue to become vested in accordance with
Section 2.1, as if a Termination shall not have occurred.

	 	2.4	 	There shall be no proportionate or partial vesting in the periods prior to each vesting
date and all vesting shall occur only on the appropriate vesting date.

	3.	 	Securities Representations. The grant of the RSUs and any issuance of shares of
Common Stock pursuant to this Agreement are being made by the Company in reliance upon the
following express representations and warranties of the Participant.

The Participant acknowledges, represents and warrants that:

	 	3.1	 	he or she has been advised that he or she may be an “affiliate” within the meaning of
Rule 144 under the Securities Act of 1933, as amended (the “Act”) and in this
connection the Company is relying in part on his or her representations set forth in this
section;

	 	3.2	 	if he or she is deemed an affiliate within the meaning of Rule 144 of the Act, the
Common Stock must be held indefinitely unless an exemption from any applicable resale
restrictions is available or the Company files an additional registration statement (or a
“re-offer prospectus”) with regard to such Common Stock and the Company is under no
obligation to register the Common Stock (or to file a “re-offer prospectus”); and

	 	3.3	 	if he or she is deemed an affiliate within the meaning of Rule 144 of the Act, he or
she understands that the exemption from registration under Rule 144 will not be available
unless (i) a public trading market then exists for the Common Stock, (ii) adequate
information concerning the Company is then available to the public, and (iii) other terms
and conditions of Rule 144 or
any exemption therefrom are complied with; and that any sale of the Common Stock may be
made only in limited amounts in accordance with such terms and conditions.

 

-2-

 

	4.	 	Not an Employment Agreement. Neither the execution of this Agreement nor the
grant of RSUs hereunder constitute an agreement by the Company to employ or to continue to
employ the Participant during the entire, or any portion of, the term of this Agreement.

	5.	 	Miscellaneous.

	 	5.1	 	This Agreement shall inure to the benefit of and be binding upon the parties hereto and
their respective heirs, personal legal representatives, successors, trustees,
administrators, distributees, devisees and legatees. The Company may assign to, and
require, any successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the Company or any
affiliate by which the Participant is employed to expressly assume and agree in writing to
perform this Agreement. Notwithstanding the foregoing, the Participant may not assign this
Agreement.

	 	5.2	 	This award of RSUs shall not affect in any way the right or power of the Board or
stockholders of the Company to make or authorize an adjustment, recapitalization or other
change in the capital structure or the business of the Company, any merger or consolidation
of the Company or subsidiaries, any issue of bonds, debentures, preferred or prior
preference stock ahead of or affecting the Common Stock, the dissolution or liquidation of
the Company, any sale or transfer of all or part of its assets or business or any other
corporate act or proceeding.

	 	5.3	 	The Participant agrees that the award of the RSUs hereunder is special incentive
compensation and that it, any dividends paid thereon (even if treated as compensation for
tax purposes) will not be taken into account as “salary” or “compensation” or “bonus” in
determining the amount of any payment under any pension, retirement or profit-sharing plan
of the Company or any life insurance, disability or other benefit plan of the Company.

	 	5.4	 	No modification or waiver of any of the provisions of this Agreement shall be effective
unless in writing and signed by the party against whom it is sought to be enforced.

	 	5.5	 	This Agreement may be executed in one or more counterparts, all of which taken together
shall constitute one contract.

	 	5.6	 	The failure of any party hereto at any time to require performance by another party of
any provision of this Agreement shall not affect the right of such party to require
performance of that provision, and any waiver by any party of any breach of any provision
of this Agreement shall not be construed as a waiver of any continuing or succeeding breach
of such provision, a waiver of the provision itself, or a waiver of any right under this
Agreement.

	 	5.7	 	The headings of the sections of this Agreement have been inserted for convenience of
reference only and shall in no way restrict or modify any of the terms or provisions
hereof.

 

-3-

 

	 	5.8	 	All notices, consents, requests, approvals, instructions and other communications
provided for herein shall be in writing and validly given or made when delivered, or on the
second succeeding business day after being mailed by registered or certified mail,

party may designate by like notice. Notices to the Company
shall be addressed to the Compensation Committee of the Board with a copy to General
Counsel, MarketAxess Holdings Inc., 299 Park Avenue, 10th Floor, New York, New
York, 10171.

	 	5.9	 	This Agreement shall be construed, interpreted and governed and the legal relationships
of the parties determined in accordance with the internal laws of the State of Delaware
without reference to rules relating to conflicts of law.

	6.	 	Provisions of Plan and Guidelines Control. This Agreement is subject to all the
terms, conditions and provisions of the Plan and the Guidelines, including, without
limitation, the amendment provisions thereof, and to such rules, regulations and
interpretations relating to the Plan and the Guidelines as may be adopted by the Committee
and as may be in effect from time to time. The Plan and the Guidelines are incorporated
herein by reference. A copy of the Plan and the Guidelines have been delivered to the
Participant. If and to the extent that this Agreement conflicts or is inconsistent with
the terms, conditions and provisions of the Plan and the Guidelines, the Plan and the
Guidelines shall control, and this Agreement shall be deemed to be modified accordingly.
Unless otherwise indicated, any capitalized term used but not defined herein shall have the
meaning ascribed to such term in the Plan or the Guidelines. This Agreement contains the
entire understanding of the parties with respect to the subject matter hereof (other than
any other documents expressly contemplated herein or in the Plan or the Guidelines) and

interest in a Global Security may exchange such beneficial interest for Definitive

Company or was, or will become, a Person that was an Affiliate of the Company within the

          (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 ”.

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

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

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.

Repurchase Notice with respect to any Security or any portion of a Security, the Paying Agent will

     (b) Timing of Payment Upon the Paying Agent’s receipt of (i) a valid Fundamental Change
Repurchase Notice (together with all necessary endorsements) and (ii) the Securities to which such

Repurchase Date for any Fundamental Change, the Paying Agent holds money sufficient to pay the
Fundamental Change Repurchase Price for every Security subject to a Fundamental
Change Repurchase Notice validly delivered in accordance with Section 3.03 hereof and not

Fundamental Change Repurchase Date:

Base Indenture, and the Trustee will authenticate, in accordance with Section 3.02 of the Base
Indenture, and deliver to the surrendering Holder, without a service charge, a new Security or

Registrar to decrease the principal amount of such Global Security by the principal amount
repurchased. Any Securities that are repurchased or owned by the Company, whether or not in
connection with a Fundamental Change, will be submitted to the Trustee for cancellation and will be

Supplemental Indenture) an amount of immediately available funds sufficient to pay the
Fundamental Change Repurchase Price of all the Securities or portions thereof that the Company
is required to repurchase on such Fundamental Change Repurchase Date.

21

 

     Section 3.09 Covenant Not to Repurchase Securities upon Certain Events of Default

     (a) General Notwithstanding anything to the contrary in this Article 3, no Securities may be
repurchased at the option of Holders upon a Fundamental Change if the principal amount of the
Securities has been accelerated, and such acceleration has not been rescinded, on or prior to such
date (except in the case of an acceleration resulting from a default by the Company that would be
cured by the Company’s payment of the Fundamental Change Repurchase Price with respect to such
Securities).

Change Repurchase Notice for a Security has been validly tendered in accordance with Section 3.03
hereof and has not been validly withdrawn in accordance with Section 3.04 hereof, and (ii) pursuant

Company in an involuntary case or proceeding or adjudicates the Company insolvent or
bankrupt;

Subsidiary of the Company;

     and, in each case, the order or decree remains unstayed and in effect for 60 consecutive days.

27

 

     (b) Cause Irrelevant Each of the events enumerated in Section 6.02(a) hereof will constitute
an Event of Default whatever the cause and regardless of whether voluntary or involuntary or
effected by operation of law or pursuant to any judgment, decree or order of any court or any
order, rule or regulation of any administrative or governmental body.

     (c) Notice of Default or Event of Default The Company shall deliver to the Trustee an
Officers’ Certificate upon the occurrence of any Default or Event of Default in accordance with
Section 4.05 of the Base Indenture.

     Section 6.03 Acceleration

     (a) Automatic Acceleration in Certain Circumstances If an Event of Default specified in
Sections 6.02(vii) or 6.02(viii) hereof occurs with respect to the Company or any Significant
Subsidiary of the Company, the principal amount of and accrued and unpaid interest, if any, on all
of the then Outstanding Securities will immediately become due and payable without any further
action or notice by any party.

     (b) Optional Acceleration If any other Event of Default occurs and is continuing, the Trustee
by notice to the Company, or the Holders of at least 25% in aggregate principal amount of then
Outstanding Securities by notice to the Company and the Trustee, may, and the Trustee at the
request of such Holders shall, declare the principal amount of and accrued and unpaid
interest, if any, on all the Outstanding Securities to be due and payable. Upon such a
declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due
and payable immediately.

     (c) Rescission of Events of Default and/or Acceleration Notwithstanding anything to the
contrary in this Indenture, the Holders of a majority in principal amount of then Outstanding
Securities may waive all past Events of Default (except with respect to nonpayment of principal
(including the Fundamental Change Repurchase Price) or interest or with respect to the Company’s
failure to deliver the Conversion Obligation as required under Article 10 hereof) and rescind any
such acceleration with respect to the Securities and its consequences hereunder by delivering
notice to the Trustee if (i) rescission would not conflict with any judgment or decree of a court
of competent jurisdiction, (ii) all existing Events of Default, other than the nonpayment of the
principal of and interest on the Securities that have become due solely by such declaration of
acceleration, have been cured or waived and (iii) all payments due under this Indenture to the
Trustee have been made.

     Section 6.04 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available
remedy to collect the payment of the principal of, accrued and unpaid interest on, or the
Fundamental Change Repurchase Price for, the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or
any Holder in exercising any right or remedy accruing upon an Event of Default 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.

28

 

     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

29

 

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.

31

 

     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.

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,

to the Trustee under Sections 4.03 or 6.07 of the Base Indenture shall survive after the Securities

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 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:

     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:

     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:

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:

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:

     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:

     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

50

 

          (i) Except as stated in this Article X, the Company will not adjust the Conversion Rate for
the issuance of shares of Common Stock or any securities convertible into or exchangeable for
shares of Common Stock or the right to purchase shares of Common Stock or such convertible or
exchangeable securities.

          (ii) In addition, notwithstanding anything herein, the Company will not be required to adjust
the Conversion Rate:

               (A) upon the issuance of:

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

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

                    (3) any shares of Common Stock pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security not described in clause (2) above and already outstanding as
of the Issue Date;

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

               (C) for accrued and unpaid interest on the Securities, if any.

     (l) Certain Definitions For purposes of this Section 10.05:

          (i) subject to Section 10.05(c) hereof, the number of shares outstanding at any time will
include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock, but, so long as the Company does not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company, will not include shares of Common Stock
held in the treasury of the Company; and

     “effective date” will mean the first date on which the Common Stock trades on the applicable
exchange or in the applicable market, regular way, reflecting the transaction.

     (m) Voluntary Adjustments

     (i) Incentive Increases The Company may from time to time increase the Conversion Rate, to
the extent permitted by law, by any amount for any period of time if such period is at least 20
Business Days.

     (ii) Tax-Related Increases The Company may also increase the Conversion Rate if the Board of
Directors determines that such increase would avoid or diminish U.S. federal income tax to holders
of the Common Stock in connection with a dividend or distribution

51

 

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.

     (n) Notices

          (i) Notice to Holders Prior to Certain Actions and Events The Company shall deliver notices of the events specified below at the times specified below
and containing the information specified below unless, in each case, (i) pursuant to this
Indenture, the Company is already required to deliver notice of such event containing at least the
information specified below at an earlier time, or, (ii) the Company, at the time it is required to
deliver a notice, does not have knowledge of all of the information required to be included in such
notice, in which case, the Company shall (A) deliver notice at such time containing only the
information that it has knowledge of at such time (if it has knowledge of any such information at
such time), and (B) promptly upon obtaining knowledge of any such information not already included
in a notice delivered by the Company, deliver notice to each Holder containing such
information. In each case, the failure by the Company to give such notice, or any defect
therein, shall not affect the legality or validity of such event.

               (A) Issuances, Distributions, and Dividends and Distributions If the Company (A) announces
any issuance of any rights, options or warrants that would require an adjustment in the Conversion
Rate pursuant to Section 10.05(b) hereof; (B) authorizes any distribution that would require an
adjustment in the Conversion Rate pursuant to Section 10.05(c) hereof (including any separation of
rights from the Common Stock described in Section 10.05(h) hereof); or (C) announces any dividend
or distribution that would require an adjustment in the Conversion Rate pursuant to Section
10.05(d) hereof, then the Company shall deliver to the Holders, as promptly as possible, but in any
event at least 35 scheduled trading days prior to the applicable Ex-Dividend Date, notice
describing such issuance, distribution, dividend or distribution, as the case may be, and stating
the expected Ex-Dividend Date and record date for such issuance, distribution, dividend or
distribution, as the case may be. In addition, the Company shall deliver to the Holders notice if
the consideration included in such issuance, distribution, dividend or distribution, or the
Ex-Dividend Date or record date of such issuance, distribution, dividend or distribution, as the
case may be, change.

               (B) Tender and Exchange Offers If the Company announces any tender or exchange offer that
could require an adjustment in the Conversion Rate pursuant to Section 10.05(e) hereof, the Company
shall deliver to the Holders on the day it announces such tender or exchange offer, and, if the
Company is 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 Rate pursuant to Section
10.05(m), the Company shall deliver notice to the Holders at least 15 days prior to the date on
which such increase will become effective, which notice shall state the date

52

 

on which such
increased will become effective and the amount by which the Conversion Rate will be increased.

               (D) Dissolutions, Liquidations and Winding-Ups If there is a voluntary or involuntary
dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the
Holders at promptly as possible, but in any event at least 35 scheduled trading days prior to the
earlier of (i) the 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 practicable, whenever the expected effective date or record date, as
applicable, 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.

ARTICLE 11

MISCELLANEOUS

     Section 11.01 Additional Elections Under Original Indenture; Ratification of Original
Indenture

     (a) The initial purchase price of the Securities shall be as set forth in the Underwriting
Agreement.

     (b) Payments on the Securities may be made only in the United States dollars and United States

different addresses for subsequent notices or communications.

     If the Company mails a notice or communication to the Holders, it will, at the same time, mail
a copy to the Trustee and each of the Registrar, Paying Agent and Conversion Agent.

     If the Company is required under this Indenture to give a notice to the Holders, in lieu of
delivering such notice to the Holders, the Company may deliver such notice to the Trustee and cause
the Trustee to have delivered such notice to the Holders on or prior to the date on which the
Company would otherwise have been required to deliver such notice to the Holders. In such a case,
the Company will also cause the Trustee to mail a copy of the notice to each of the Registrar,
Paying Agent and Conversion Agent at the same time it mails the notice to the Holders.

     Section 11.04 Waiver of Jury Trial and Submission to Jurisdiction

     The Company: (a) agrees that any suit, action or proceeding against it arising out of or
relating to this Indenture or any Securities, as the case may be, may be instituted in any United
States federal court with applicable subject matter jurisdiction sitting in The City of New York;
(b) waives, to the fullest extent permitted by applicable law, any objection which it may now or
hereafter have to the laying of venue of any such suit, action or proceeding, and any claim that
any suit, action or proceeding in such a court has been brought in an inconvenient forum; and (c)
submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding.

     Section 11.05 Calculations. Except as otherwise provided in this Indenture, the Company will be responsible for making
all calculations called for under the Securities and this Indenture. These calculations include,
but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock,
accrued interest payable on the Securities and the Conversion Rate of the Securities.

     The Company will make these calculations in good faith and, absent manifest error, the
Company’s calculations will be final and binding on Holders. If the Trustee or the Conversion
Agent request a schedule detailing any of the Company’s calculations, the Company will provide such
a schedule to the Trustee 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, promptly forward a copy of it to such Holder.

     All calculations will be made to the nearest cent or to the nearest 1/10,000th of a share, as
the case may be.

59

 

     Section 11.06 Confirmation of Indenture. The Base Indenture, as supplemented and amended by this Supplemental Indenture and all
other indentures supplemental thereto, is in all respects ratified and confirmed, and the Base
Indenture, this Supplemental Indenture and all indentures supplemental thereto shall be read, taken
and construed as one and the same instrument.

other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent,
any Registrar and their successors hereunder or the Holders, any benefit or any legal or equitable

authority, any act of God or war, civil unrest, local or national disturbance or disaster, any act
of terrorism, or the unavailability of the Federal Reserve Bank wire or facsimile or other wire or

[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

 

A-4

 

 

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.
