GENERAL TERMS CONTRACT A — Supplementary credit for purposes other than personal consumption,
applying from 21 December 2009

	1.	 	General terms for accounts held with Handelsbanken
	 
	 	 	The borrower disposes of the account in accordance with the
terms applying to the account to which
the overdraft facility is linked. The Bank may withdraw funds from the account if the borrower has
ordered this or has approved that the account may be debited.
	 
	 	 	The Bank may also debit the account with amounts corresponding to interest, charges and costs which
are associated with the account. In addition, the Bank may debit the account with amounts
corresponding to charges, costs and outlays for orders effected on behalf of the borrower and for
payment of other due claims which the Bank has on the borrower.
	 
	 	 	When the Bank is entitled to debit the account as stated in the previous paragraph, this may also
be done as at a day which is a public holiday or equivalent day. It is the duty of the borrower to
ensure that a sufficiently large amount is available on the account when the debit occurs. If the
borrower dies during the contract period, the estate of the deceased may not increase the debt on
the account without the consent of the Bank.
	 
	2.	 	Interest
	 
	 	 	The borrower shall pay utilisation interest to the Bank at an annual rate computed on the overdraft
amount outstanding at any time, plus contract interest on the granted overdraft amount. The
utilisation interest is calculated at the interest rate and on the grounds which the Bank applies
to this type of facility from time to time. The interest rates applying when the facility was
provided are set out in the contract. If different interest rates are applied for utilisation
interest in different ranges of the overdraft amount, this is indicated on page one with the
interest rates applying when the contract was entered into.
	 
	 	 	In the event of an extension of the
facility, additional contract interest is payable for each period of extension, this being payable
in advance for the period concerned.
	 
	 	 	The borrower is liable for contract interest for the period
until the end of the overdraft period set out in the contract, without any obligation for the Bank
to make a refund if the contract should be terminated before then.
	 
	3.	 	Overdrafts
	 
	 	 	If the borrower’s debt to the Bank under this contract exceeds the amount granted, the
borrower shall upon demand pay the difference. In this case, the borrower shall also pay interest
on the overdrawn amount at the rate and on the grounds applied by the Bank at any time, as well as
an unauthorised overdraft fee as set out in section 5 below.
	 
	 	 	Unauthorised overdrafts also entitle the Bank to terminate the facility for repayment and/or
suspend utilisation of the facility in advance. In this case the provisions in section 8 will
apply.
	 
	4.	 	Penalty interest
	 
	 	 	If payment of principal, interest and/or charges is not effected when due, the borrower shall pay
special annual penalty interest on the overdue amount until payment
is made. On amounts not
overdue, the usual interest rate continues to apply.
	 
	 	 	Penalty interest is calculated at the
utilisation interest rate applying to the facility, plus five percentage points or, when the entire
facility is overdue, one percentage point.
	 
	5.	 	Charges and costs
	 
	 	 	The account is subject to charges according to the terms generally applied from time to time by the Bank. Particulars of cur-
rent charges are available at any of the Bank’s branches.
	 
	 	 	The borrower shall reimburse the Bank for the costs and work
associated with obtaining, maintaining and utilising the security
agreed upon, as well as with the lodging of proof and collection
of the Bank’s claim on the borrower or on any other party liable
for payment thereof. The Bank’s written payment reminders
shall thus also be reimbursed.
	 
	6.	 	Order of debt settlement
	 
	 	 	When payment is made, the Bank is entitled to deduct the charges, costs and interest due on the
facility before settling the principal amount.
	 
	7.	 	Facility period
	 
	 	 	The facility period for the supplementary overdraft facility is set out in the contract and will
not be extended. If the Bank does not grant an extension of the normal overdraft facility or if the
normal overdraft facility is terminated for payment in advance, the supplementary overdraft
facility shall be due for payment at the same time as the normal overdraft facility irrespective of
whether the agreed facility period for the supplementary overdraft facility is longer or the
supplementary overdraft facility has not been subject to separate notice of termination.
	 
	8.	 	The Bank’s right to terminate the facility and/or suspend utilisation of the facility
	 
	 	 	The Bank may terminate the facility for payment immediately or at any time determined by the Bank
and suspend utilisation of the overdraft facility, if any of the following circumstances
should apply:

	 	•	 	the borrower has failed to meet his obligations under this
contract or otherwise to the Bank,
	 
	 	•	 	the borrower has used the account improperly in a manner
set out under Section 3,
	 
	 	•	 	the collateral for the loan or for other obligations of the borrower towards the Bank is no longer satisfactory,
	 
	 	•	 	there is reasonable cause to assume that the borrower will
not meet his payment obligations to the Bank.

	 	 	If any of the circumstances set out above are present, the Bank is entitled, regardless of
whether termination has been made, to immediately suspend the right to utilise the facility
further.
	 
	 	 	If the Bank has terminated the facility in accordance with this section, the borrower
shall immediately return unused cheques and other instruments for operating the account.
	 
	9.	 	Closing bill and refund
	 
	 	 	When the agreed overdraft period has expired or when the facility is payable in advance pursuant to
section 3, 7 or 8, the Bank shall prepare a closing bill.
	 
	 	 	The borrower must immediately pay the debt according to the closing bill.
	 
	10.	 	Definition of a pledge, etc.
	 
	 	 	‘Pledge’ also refers to property that is included in a floating charge on
assets. The term ‘pledger’ also refers to an assignor of floating charge,
‘pledging’ also refers to assignment of the floating charge and
‘pledge deed’ also refers to deeds associated with a floating charge and pledge
claims.
	 
	11.	 	The Bank’s right to sell pledged financial instruments
	 
	 	 	If the security for the loan consists in full or in part of financial instruments and if the value
for borrowing purposes assigned by the Bank declines, implying that the security is no longer
satisfactory, the borrower must at the request of the Bank immediately provide additional security.
If such security is not provided, or if the Bank is unable to contact the borrower within a
reasonable period of time, the Bank has the right, but not the obligation, to sell the required
portion of the financial instruments. The proceeds shall be deposited to an interest-bearing
account and continue to constitute a pledge for the loan. That which is stated above does not
restrict the Bank’s right to terminate the facility for immediate payment in accordance
with section 8 and/or the right to immediately suspend utilisation of the facility in accordance
with section 8.
	 
	12.	 	Right of guarantor and pledger to prevent extension of overdraft period
	 
	 	 	A guarantor is not entitled to terminate his guarantee and a pledger may not revoke his mortgage.

Page 1 of 3 

 

Handelsbanken

	 	 	However, any guarantor or pledger may separately, not later than six weeks before the due date of
the facility, request in writing that the Bank shall not extend the facility. Such request may
imply that the guarantor becomes forced to pay by virtue of his guarantee, or that the Bank
utilises a pledge.
	 
	 	 	If the Bank within the period set out in the preceding paragraph has received a
request that the facility shall not be extended but nevertheless extends the facility, the
guarantee or pledge provided by the party making such request ceases to be valid. This does not
apply, however, if the Bank, due to the borrower’s negligence, before expiry of the
aforementioned time period, has commenced legal proceedings against the party who has opposed an
extension or has commenced negotiation with this party concerning the guarantee commitment or
pledge.
	 
	13.	 	Sequence of utilisation of security
	 
	 	 	If the borrower fails to meet his obligations under the contract, the Bank may determine the
sequence in which the securities (pledges, guarantees, etc.) shall be utilised.
	 
	14.	 	General right of pledge
	 
	 	 	Property pledged by the borrower in this contract shall also constitute security for any other
obligations towards the Bank for which the borrower is or may in the future be liable, in his
capacity as borrower, principal, account holder, guarantor or otherwise as customer of the Bank.
Such other obligation must have arisen before the borrower’s obligations under this
contract have been met. The Bank shall determine in which order the obligations
are to be settled out of the proceeds of the pledge. However, account must be taken of the right of
guarantors according to section 22.
	 
	 	 	Property thus pledged shall not, however, by reason of the pledge, constitute security for the
borrower’s obligations on account of bills of exchange which have been discounted, or
which may be discounted at the Bank by a third party, unless they concern the renewal of bills, or
have otherwise replaced bills originally discounted by the borrower. Neither shall the property
thus pledged secure any other claims on the borrower which the Bank has acquired or may acquire
from a third party.
	 
	15.	 	Yield on property pledged
	 
	 	 	Yield and all other rights based on the pledge are also covered by the pledging and constitute a
pledge. Thus, the pledging of shares, for example, includes the right of the Bank to participate in
bonus issues, new issues and other issues for which the shares qualify. As stated in section 16,
the Bank is, however, not liable for ensuring that such rights are safeguarded. Where this
nevertheless occurs, the Bank is accountable to the pledger.
	 
	16.	 	Safeguard by the Bank of the pledge
	 
	 	 	The Bank has a duty to take good care of the pledge. 

Where appropriate, the Bank shall renew
limitation periods and lodge proof of claim in case of summons of unknown creditors and also in
bankruptcies, where the pledger so requests after commencement of the bankruptcy. Where
announcement has been made regarding the cancellation of a pledged document, the Bank shall give
notice that it holds the document. However, the Bank is not obliged to take any of these measures
regarding certificates of claim consisting of coupons or which are intended for the open market,
such as bonds, or to which Swedish law does not apply.
	 
	 	 	The Bank is not obliged to maintain personal liability for payment in respect of mortgaged
instruments of debt.
	 
	 	 	The Bank’s safeguard of the pledge does not extend beyond what has
been stated above. Thus the Bank is not, for example,
as far as securities are concerned, obliged to collect dividends
and interest or observe the pledger’s rights in connection with
issues, exchanges of shares, conversions, distributions of net
assets, etc.
	 
	17.	 	How a pledge may be utilised by the Bank
	 
	 	 	The Bank may utilise a pledge as the Bank deems fit. In this respect, the Bank shall proceed with care and, where possible
and if in the opinion of the Bank it can be accomplished without
prejudice to the Bank, notify the pledger to this effect in advance.
	 
	 	 	When applying the above, a financial instrument can be sold in a different way than on a market
where the instrument is registered or is normally traded.
	 
	 	 	If the pledge consists of funds deposited in an account with the Bank, the Bank may immediately
debit the account in reimbursement of the amount due, without informing the pledger in advance.
	 
	 	 	Should the pledge consist of an instrument of debt for which the pledger is liable personally or
with certain property, the instrument is, with respect to the pledger, due for payment on demand,
regardless of the due date stipulated in the instrument.
	 
	18.	 	The Bank’s right to sign on behalf of the pledger
	 
	 	 	Through his pledging, the pledger authorises the Bank, or anyone appointed by the Bank, to sign on
behalf of the pledger, where this is necessary in order to safeguard the Bank’s right of
pledge. This authorisation may not be revoked as long as the pledging is in force.
	 
	19.	 	Release of pledge
	 
	 	 	The Bank may release pledges without being bound to observe any right to the pledge which may
accrue to a guarantor who has made payment to a party other than the Bank by virtue of his
guarantee.
	 
	20.	 	Transfer of unpledged deeds of mortgage
	 
	 	 	When the Bank no longer holds the pledge and has not been informed of a new pledge-holder or
received a request that a written deed of mortgage shall be issued, the Bank is entitled to
transfer an electronic deed of mortgage to the National Land Survey’s register of
mortgages for which no other mortgage-holder is registered, known as the Public Archive.
	 
	21.	 	Payment by the guarantor
	 
	 	 	If a guarantor makes payment to the Bank on account of his guarantee, he shall specifically notify
the Bank that he is paying in his capacity as guarantor and request that this fact be noted by the
Bank.
	 
	22.	 	Guarantor’s right to pledges
	 
	 	 	If a guarantee has been signed on this contract, the following shall apply with regard to the
guarantor’s right to pledges in this contract by the borrower alone or jointly with
another:
	 
	 	 	The pledge shall constitute security for the guarantor’s claim for recourse
against the borrower to the extent that it is not utilised by the Bank for the borrower’s
obligations under this contract. When the pledge constitutes security for the right of recourse of
several guarantors, they shall have rights to the pledge in proportion to the right of recourse of
each of them, unless they agree otherwise.
	 
	 	 	In relation to the Bank, a guarantor is not entitled to any other property which has been pledged
to the Bank by the borrower or another party.
	 
	 	 	The Bank may release yield from the pledge which is not required for payment of amounts due under
this contract, without thereby reducing the liability of any guarantor.
	 
	23.	 	How the pledge may be utilised for a guarantor’s right of recourse
	 
	 	 	Where a guarantor has made payment to the Bank by virtue of his guarantee, he may exercise his
right to a pledge under section 22 only when the Bank has received payment in full for its claim
under this contract. If the guarantor wishes to exercise this right, the Bank is entitled to choose
between releasing the pledge to the guarantor or utilising the pledge on behalf of the guarantor.
Section 17 shall apply in this connection.
	 
	24.	 	Property pledged by a party other than the borrower
	 
	 	 	Property pledged on this contract by a party other than the borrower shall constitute security only for the borrower’s obligations
under this contract, unless otherwise agreed.
	 
	 	 	Without any reduction of the Bank’s right to property which a party other than the
borrower has pledged on this contract, the Bank is entitled to release property pledged by the
borrower or any other party, which has not been pledged on this contract, as well as the yield on
such property. The Bank is also entitled to release the yield on property pledged on this contract
by the

Page 2 of 3 

 

Handelsbanken

	 	 	borrower or any other party, if the yield is due for payment but is not required to cover interest
or costs due under the contract.
	 
	25.	 	Cancellation of the contract
	 
	 	 	The contract will be cancelled one month after the overdraft has been repaid in full, unless the
borrower has asked in advance for it to be returned.
	 
	26.	 	Insurance
	 
	 	 	Property which constitutes security for the Bank’s claim shall be satisfactorily insured.
	 
	 	 	If the borrower fails to show proof that insurance as prescribed above is in force, the Bank shall
be entitled to arrange for such insurance at the borrower’s expense.
	 
	27.	 	Processing of personal data
	 
	 	 	Personal data submitted in connection with a credit application or otherwise registered in
connection
with processing or administration of this credit will be subject to such processing in computer
systems at the Bank as required by the credit agreement. This includes information about contacts
between the borrower and the Bank.
	 
	 	 	This promissory note contains special information on the processing of data for credit references.
	 
	 	 	The personal data is also used for marketing and customer research, business and methods
development and risk management in the Handelsbanken Group. Risk management also involves
processing information on the borrower and loans to assess the quality of loans for purposes of
capital adequacy.
	 
	 	 	The personal data is also used for marketing purposes, unless the borrower has
requested a block on direct advertising from the Bank. The processing of personal data can — within
the framework of current bank confidentiality regulations — take place with other Group companies
and other companies with whom the Bank collaborates in its operations.
	 
	 	 	If the borrower requires
information about the personal data about him/her which is being processed by the Bank, the
borrower can request this in writing from his/her branch of the Bank. Requests to correct
incomplete or incorrect personal data can be made at the Bank branch or sent to Handelsbanken,
Central auditing department, SE-106 70 Stockholm, Sweden.
	 
	 	 	The above statements regarding borrowers
also apply to guarantors, if any, or pledgers other than the borrower.
	 
	28.	 	Notices, etc.
	 
	 	 	The borrower, guarantors and pledgers shall notify the Bank of any changes of address, telephone
number or fax number.
	 
	 	 	Registered letters regarding the overdraft facility which the Bank has
forwarded to any of the parties mentioned above shall be deemed to have reached the addressee not
later than on the seventh day after despatch if the letter has been sent to the address which is
known to the Bank.
	 
	 	 	Notices sent by fax shall be deemed to have reached the addressee no later than the next business
day if the fax message was sent to a number which the addressee has submitted to the Bank. A
business day is a day other than a Sunday, public holiday, Saturday, Midsummer’s Eve,
Christmas Eve or New Year’s Eve.
	 
	 	 	These provisions do not apply to notices renewing periods of limitation.
	 
	29.	 	Limitation of the Bank’s liability
	 
	 	 	The Bank shall not be held responsible for any loss or damage resulting from a legal enactment
(Swedish or foreign), the intervention of a public authority (Swedish or foreign), an act of war, a
strike, a blockade, a boycott, a lockout or any other similar circumstance. The reservation in
respect of strikes, blockades, boycotts and lockouts applies even if the Bank itself is subjected
to such measures or takes such measures.
	 
	 	 	Any damage which occurs in other circumstances shall not
be compensated by the Bank, provided the Bank has exercised normal standards of care. The Bank
shall in no case be liable for indirect damage.
	 
	 	 	Where a circumstance as referred to in the first paragraph should prevent the Bank from making a
payment or taking other measures, such payment or measures may be postponed until the obstacle no
longer exists. In the event of a postponement of payment the Bank shall, if it is committed to pay
interest, pay such interest at the interest rate prevailing on the due date for the postponed
payment. Where the Bank is not committed to pay interest, the Bank shall not be obliged to pay
interest at a higher rate than the prevailing reference rate of Sveriges Riks-bank pursuant to the
Section 9 of the Interest Act (1975:635), plus two percentage points. Where a circumstance as
referred to in the first paragraph should prevent the Bank from receiving payments, the Bank shall,
as long as the obstacle exists, be entitled to interest only on the terms prevailing on the due
date of the payment.

ARTICLE 2

The Securities

     Section 2.01. Designation, Amount and Issuance of Securities. The Securities shall be
designated as “2.75% Senior Convertible Debentures Due 2031.” The Securities will initially be
issued in the aggregate principal amount of $690,000,000. The Company may issue additional
securities in accordance with Section 2.17. Upon the execution of this Indenture, or from time to
time thereafter, Securities may be executed by the Company and delivered to the Trustee for
authentication, and the Trustee shall thereupon authenticate and deliver Securities upon a written
order of the Company, such order signed by an Officer of the Company, without any further action by
the Company hereunder.

     Section 2.02. Form of the Securities. The Securities and the Trustee’s certificate of
authentication to be borne by such Securities shall be substantially in the form set forth in
Exhibit A hereto. The terms and provisions contained in the form of Securities attached as Exhibit
A hereto shall constitute, and are hereby expressly made, a part of this Indenture and, to the
extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby.

     Any of the Securities may have such letters, numbers or other marks of identification and such
notations, legends, endorsements or changes as the officers executing the same may approve
(execution thereof to be conclusive evidence of

12

 

such approval) and as are not inconsistent with the
provisions of this Indenture, or as may be required by the custodian for the Global Securities, the
Depositary or as may be required to comply with any applicable law or any regulation thereunder or
with the rules and regulations of any securities exchange or automated quotation system upon which
the Securities may be listed or traded or designated for issuance or to conform with any usage with
respect thereto, or to indicate any special limitations or restrictions to which any particular
Securities are subject.

     So long as the Securities are eligible for book-entry settlement with the Depositary, or
unless otherwise required by law, subject to Section 2.09, all of the Securities will be
represented by one or more Securities in global form registered in the name of the Depositary or
the nominee of the Depositary (“Global Securities”). The transfer and exchange of beneficial
interests in any such Global
Securities shall be effected through the Depositary in accordance with this Indenture and the
applicable procedures of the Depositary. Except as provided in Section 2.09, beneficial owners of
a Global Security shall not be entitled to have certificates registered in their names, will not
receive or be entitled to receive physical delivery of certificates in definitive form and will not
be considered Holders of such Global Security.

     Any Global Securities shall represent such of the outstanding Securities as shall be specified
therein and shall provide that it shall represent the aggregate amount of outstanding Securities
from time to time endorsed thereon and that the aggregate amount of outstanding Securities
represented thereby may from time to time be increased or reduced to reflect issuances,
redemptions, repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of
a Global Security to reflect the amount of any increase or decrease in the amount of outstanding
Securities represented thereby shall be made by the Trustee or the custodian for the Global
Security, at the direction of the Trustee, in such manner and upon instructions given by the Holder
of such Securities in accordance with this Indenture. Payment of principal of, and interest on,
any Global Securities shall be made to the Depositary in immediately available funds.

     Section 2.03. Date and Denomination of Securities; Payment at Maturity; Payment of Interest.
The Securities shall be issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. Each Security shall be dated the date of its
authentication and shall bear interest from the date specified on the face of the form of
Securities attached as Exhibit A hereto. Interest on the Securities shall be computed on the basis
of a 360-day year comprised of twelve 30-day months.

     On the Maturity Date, each Holder shall be entitled to receive on such date the principal
amount of the Securities held and accrued and unpaid interest to, but not including, the Maturity
Date. With respect to Global Securities, principal and interest will be paid to the Depositary in
immediately available funds. With respect to any certificated Securities, principal and interest
will be payable at the

13

 

Company’s office or agency maintained for that purpose, which initially will
be the Trustee’s office at 100 Wall Street, Suite 1600, New York, NY 10005.

     The Person in whose name any Security is registered on the Register at 5:00 p.m., New York
City time, on any Interest Record Date with respect to any interest payment date shall be entitled
to receive the interest payable on such interest payment date.

     Notwithstanding the foregoing, any Securities or portion thereof surrendered for conversion
during the period after the Interest Record Date for any interest payment date and ending prior to
the corresponding interest payment date shall be accompanied by payment, in immediately available
funds or other funds acceptable to the Company, of an amount equal to the interest otherwise
payable on such interest payment date on the principal amount being converted;
provided that no such payment need be made (1) if a Holder converts its Securities that have
been called for redemption and the Company has specified a Redemption Date that is after an
Interest Record Date and on or prior to the corresponding interest payment date, (2) if a Holder
converts its Securities following a Fundamental Change and the Company has specified a Fundamental
Change Repurchase Date that is after an Interest Record Date and on or prior to the corresponding
interest payment date, (3) for any conversion following the Interest Record Date immediately
preceding the Maturity Date, or (4) to the extent of any overdue interest, if overdue interest
exists at the time of conversion with respect to such Securities.

     Except as provided above, the Company shall pay interest (i) on any Global Securities by wire
transfer of immediately available funds to the account of the Depositary or its nominee, (ii) on
any Securities in certificated form having a principal amount of less than $2,000,000, by check
mailed to the address of the Person entitled thereto as it appears in the Register, provided that
at maturity, interest will be payable at the office of the Company maintained by the Company for
such purposes, which shall initially be an office or agency of the Trustee located at 100 Wall
Street, Suite 1600, New York, NY 10005 and (iii) on any Securities in certificated form having a
principal amount of $2,000,000 or more, by wire transfer in immediately available funds at the
election of the Holder of such Securities who has duly delivered notice of such election and
applicable wire instructions to the Trustee at least five Business Days prior to the relevant
interest payment date, provided that at maturity, interest will be payable at the office of the
Company maintained by the Company for such purposes, which shall initially be an office or agency
of the Trustee located at 100 Wall Street, Suite 1600, New York, NY 10005. If a payment date is
not a Business Day, payment shall be made on the next succeeding Business Day, and no interest will
be payable on such interest payment in respect of the delay.

     Upon the conversion of any Securities, the accrued but unpaid interest attributable to the
period from the issue date of the Securities to the Conversion

14

 

Date, with respect to the converted
Securities, shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be
paid in full to the Holder thereof through delivery of the cash (including a cash payment in lieu
of fractional shares, if any) and shares of Common Stock, if any, in exchange for the Securities
being converted pursuant to the provisions hereof.

     Section 2.04. Execution and Authentication. One or more Officers shall sign the Securities
for the Company by manual or facsimile signature.

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

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

     The Trustee may appoint an authenticating agent reasonably acceptable to the Company to
authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a
Trust Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by
such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

     Section 2.05. Registrar, Paying Agent and Conversion Agent. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer or for exchange
(the “Registrar”), an office or agency where Securities may be presented for payment (the “Paying
Agent”) and an office or agency where Securities may be presented for conversion (the “Conversion
Agent”). The Corporate Trust Office shall be considered as one such office or agency of the
Company for each of the aforesaid purposes. The Registrar shall keep a register of the Securities
(the “Register”) and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term “Paying Agent” includes any
additional paying agent, and the term “Registrar” includes any co-registrars. The Company
initially appoints the Trustee as (i) Registrar and Paying Agent in connection with the Securities,
(ii) the custodian with respect to the Global Securities and (iii) Conversion Agent.

     The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent
or Conversion Agent not a party to this Indenture, which shall incorporate the terms of the TIA if
required by the TIA. The agreement shall implement the provisions of this Indenture that relate to
such agent. The

15

 

Company shall notify the Trustee of the name and address of any such agent. If
the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act
as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically organized Wholly Owned Subsidiaries may act as Paying Agent,
Conversion Agent or Registrar.

     The Company may remove any Registrar, Paying Agent or Conversion Agent upon written notice to
such Registrar, Paying Agent or Conversion Agent and to the Trustee; provided that no such removal
shall become effective until (1) acceptance of an appointment by a successor as evidenced by an
appropriate agreement entered into by the Company and such successor Registrar, Paying Agent or
Conversion Agent, as the case may be, and delivered to the Trustee or (2) notification to the
Trustee that the Trustee shall serve as Registrar, Paying Agent or Conversion Agent until the
appointment of a successor in accordance with clause (1) above. The Registrar, Paying Agent or
Conversion Agent may resign
at any time upon written notice; provided that the Trustee may resign as Paying Agent,
Conversion Agent or Registrar only if the Trustee also resigns as Trustee in accordance with
Section 7.08.

     Section 2.06. Paying Agent to Hold Money in Trust. On or prior to each due date of the
principal and interest on any Security, the Company shall deposit with the Paying Agent (or if the
Company or a Wholly Owned Subsidiary of the Company is acting as Paying Agent, segregate and hold
in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal
and interest when so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of
Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of
or interest on the Securities and shall notify the Trustee of any default by the Company in making
any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent,
it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to
account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

     Section 2.07. Securityholder Lists. The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish, or cause the
Registrar to furnish, to the Trustee, in writing at least five Business Days before each interest
payment date and at such other times as the Trustee may request in writing, a list in such form and
as of such date as the Trustee may reasonably require of the names and addresses of
Securityholders.

16

 

     Section 2.08. Exchange and Registration of Transfer of Securities. The Company shall cause
to be kept at the Corporate Trust Office the Register in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities. The Register shall be in written form or in any form capable of being
converted into written form within a reasonably prompt period of time.

     Upon surrender for registration of transfer of any Securities to the Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.08
and in Section 2.10, the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities of any authorized
denominations and of a like aggregate principal amount and bearing such restrictive legends as may
be required by this Indenture.

     Securities may be exchanged for other Securities of any authorized denominations and of a like
aggregate principal amount and bearing such
restrictive legends as may be required by this Indenture, upon surrender of the Securities to
be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02.
Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to
receive bearing registration numbers not contemporaneously outstanding.

     All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

     All Securities presented or surrendered for registration of transfer or for exchange,
redemption, repurchase or conversion shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory
to the Company, duly executed by the Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made to any Holder for any registration of, transfer or exchange of
Securities, but the Company may require payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities.

     Neither the Company nor the Trustee nor any Registrar shall be required to exchange, issue or
register a transfer of (a) any Securities for a period of fifteen calendar days next preceding the
date of mailing of a notice of redemption, (b) any Securities or portions thereof called for
redemption pursuant to Section 3.02, except for the unredeemed portion of any Securities being
redeemed in part, (c)

17

 

any Securities or portions thereof surrendered for conversion pursuant to
Article 10, (d) any Securities or portions thereof tendered for repurchase (and not withdrawn)
pursuant to Section 3.04 or (e) any Securities or portions thereof tendered for repurchase (and not
withdrawn) pursuant to Section 3.05.

     Section 2.09. Global Securities. The following provisions shall apply to Global Securities:

     (a) Each Global Security authenticated under this Indenture shall be registered in the name of
the Depositary or a nominee thereof and delivered to the Depositary or a nominee thereof or
custodian for the Global Securities therefor, and each such Global Security shall constitute a
single Security for all purposes of this Indenture.

     (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged
in whole or in part for Physical Securities registered, and no transfer of a Global Security in
whole or in part may be registered, in the name of any Person other than the Depositary or a
nominee thereof unless (A) the
Depositary (x) has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Security or (y) has ceased to be a clearing agency registered under the
Exchange Act, and a successor depositary has not been appointed by the Company within 90 calendar
days, or (B) the Company, in its sole discretion, notifies the Trustee in writing that it no longer
wishes to have all the Securities represented by Global Securities. Any Global Securities
exchanged pursuant to this Section 2.09(b) shall be so exchanged in whole and not in part.

     (c) In addition, Physical Securities will be issued in exchange for beneficial interests in a
Global Security upon request by or on behalf of the Depositary in accordance with customary
procedures following the request of a beneficial owner seeking to enforce its rights under the
Securities or this Indenture upon the occurrence and during the continuance of an Event of Default.

     (d) Physical Securities issued in exchange for a Global Security or any portion thereof
pursuant to Section 2.09(b) or Section 2.09(c) shall be issued in definitive, fully registered
form, without interest coupons, shall have an aggregate principal amount equal to that of such
Global Securities or portion thereof to be so exchanged, shall be registered in such names and be
in such authorized denominations as the Depositary shall designate and shall bear any legends
required hereunder. Any Global Securities to be exchanged shall be surrendered by the Depositary
to the Trustee, as Registrar, provided that pending completion of the exchange of a Global
Security, the Trustee acting as custodian for the Global Securities for the Depositary or its
nominee with respect to such Global Securities, shall reduce the principal amount thereof, by an
amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made
on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall
authenticate and make available for delivery the Physical Securities issuable

18

 

on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

     (e) In the event of the occurrence of any of the events specified in Section 2.09(b) above or
upon any request described in Section 2.09(c), the Company will promptly make available to the
Trustee a sufficient supply of Physical Securities in definitive, fully registered form, without
interest coupons.

     (f) Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other
Persons on whose behalf Agent Members may act shall have any rights under this Indenture with
respect to any Global Securities registered in the name of the Depositary or any nominee thereof,
and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner and Holder of such Global
Securities for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to
any written certification, proxy or other authorization furnished by the Depositary or such
nominee, as the case may be, or impair, as between the Depositary, its Agent
Members and any other Person on whose behalf an Agent Member may act, the operation of
customary practices of such Persons governing the exercise of the rights of a Holder of any
Securities.

     (g) At such time as all interests in a Global Security have been redeemed, repurchased,
converted, cancelled or exchanged for Securities in certificated form, such Global Security shall,
upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and
instructions existing between the Depositary and the custodian for the Global Security. At any
time prior to such cancellation, if any interest in a Global Security is redeemed, repurchased,
converted, cancelled or exchanged for Securities in certificated form, the principal amount of such
Global Security shall, in accordance with the standing procedures and instructions existing between
the Depositary and the custodian for the Global Security, be appropriately reduced, and an
endorsement shall be made on such Global Security, by the Trustee or the custodian for the Global
Security, at the direction of the Trustee, to reflect such reduction.

     Section 2.10. Transfer Restrictions.

     (a) Every Security that bears or is required under this Section 2.10(a) to bear the legend set
forth in this Section 2.10(a) (together with any Common Stock issued upon conversion of the
Securities and required to bear the legend set forth in Section 2.10(b), collectively, the
“Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section
2.10(a) (including the legend set forth below), unless such restrictions on transfer shall be
eliminated or otherwise waived by written consent of the Company, and the Holder of each such
Restricted Security, by such Holder’s acceptance thereof, agrees to be bound

19

 

by all such restrictions on transfer. As used in this Section 2.10(a) and Section 2.10(b), the term
“transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted
Security.

     Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date
that is one year after the Last Date of Original Issuance, or such shorter period of time as
permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such
later date, if any, as may be required by applicable law, any certificate evidencing such Security
(and all securities issued in exchange therefor or substitution thereof, other than Common Stock,
if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.10(b), if
applicable) shall bear a legend in substantially the following form (unless such Securities have
been transferred pursuant to a registration statement that has become or been declared effective
under the Securities Act and that continues to be effective at the time of such transfer, or sold
pursuant to the exemption from registration provided by Rule 144 or any similar provision then in
force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice
thereof to the Trustee):

     THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE.
BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

     (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED
INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT
IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

     (2) AGREES FOR THE BENEFIT OF NUANCE COMMUNICATIONS, INC. (THE “COMPANY”) THAT IT
WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL
INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST
ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER
THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO, AND (Y) SUCH LATER DATE, IF ANY, AS
MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

     (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

20

 

     (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER
THE SECURITIES ACT, OR

     (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER
THE SECURITIES ACT, OR

     (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

     PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(D) ABOVE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER
EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE
PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE
SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

     No transfer of any Security prior to the Resale Restriction Termination Date will be
registered by the Registrar unless the applicable box on the Form of Assignment has been checked.

     Any Security (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of
such Security for exchange to the Registrar in accordance with the provisions of this Article 2, be
exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.10(a) and shall not be assigned a
restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so
surrender any Global Security as to which such restrictions on transfer shall have expired in
accordance with their terms for exchange, and, upon such instruction, the Custodian shall so
surrender such Global Security for exchange; and any new Global Security so exchanged therefor
shall not bear the restrictive legend specified in this Section 2.10(a) and shall not be assigned a
restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the
Resale Restriction Termination Date and promptly after a registration statement, if any, with
respect to the Securities or any Common Stock issued upon conversion of the Securities has been
declared effective under the Securities Act.

21

 

     Notwithstanding any other provisions of this Indenture (other than the provisions set
forth in this Section 2.10(a)), a Global Security may not be transferred as a whole or in part
except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions
of a Global Security in certificated form made upon request of a member of, or a participant in,
the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the
Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary
and in compliance with this Section 2.10(a).

     The Depositary shall be a clearing agency registered under the Exchange Act. The Company
initially appoints The Depository Trust Company to act as Depositary with respect to each Global
Security. Initially, each Global Security shall be issued to the Depositary, registered in the
name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian
for Cede & Co.

     Physical Securities issued in exchange for all or a part of the Global Securities pursuant to
this Section 2.10(a) shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical
Securities to the Persons in whose names such Physical Securities are so registered.

     (b) Until the Resale Restriction Termination Date, any stock certificate representing Common
Stock issued upon conversion of such Security, if any, shall bear a legend in substantially the
following form (unless the Security or such Common Stock has been transferred pursuant to a
registration statement that has become or been declared effective under the Securities Act and that
continues to be effective at the time of such transfer, or pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act,
or such Common Stock has been issued upon conversion of Securities that have been transferred
pursuant to a registration statement that has become or been declared effective under the
Securities Act and that continues to be effective at the time of such transfer, or pursuant to the
exemption from registration provided by Rule 144 or any similar provision then in force under the
Securities Act, or unless otherwise agreed by the Company with written notice thereof to the
Trustee and any transfer agent for the Common Stock):

     THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
ACCORDANCE WITH THE FOLLOWING

22

 

SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

     (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED
INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT
IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

     (2) AGREES FOR THE BENEFIT OF NUANCE COMMUNICATIONS, INC. (THE “COMPANY”) THAT IT
WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL
INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST
ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER
THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS
MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

     (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

     (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER
THE SECURITIES ACT, OR

     (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER
THE SECURITIES ACT, OR

     (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

     PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(D) ABOVE, THE COMPANY AND THE
TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER
EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING
MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION
IS MADE AS TO THE AVAILABILITY OF ANY

23

 

EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT.

     Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon surrender of the certificates representing such shares of
Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of
Common Stock, which shall not bear the restrictive legend required by this Section 2.10(b).

     (c) Any Security or Common Stock issued upon the conversion or exchange of a Security that is
repurchased or owned by the Company or any Affiliate thereof may not be resold by the Company or
such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from
the registration requirements of the Securities Act in a transaction that results in such
Securities or Common Stock, as the case may be, no longer being “restricted securities” (as defined
under Rule 144 under the Securities Act).

     Section 2.11. Responsibilities and Obligations of the Trustee. The Trustee shall have no
responsibility or obligation to any Agent Members or any other Person with respect to the accuracy
of the books or records, or the acts or omissions, of the Depositary or its nominee or of any
participant or member thereof, with respect to any ownership interest in the Securities or with
respect to the delivery to any Agent Member or other Person (other than the Depositary) of any
notice (including any notice of redemption) or the payment of any amount, under or with respect to
such Securities. All notices and communications to be given to the Holders of Securities and all
payments to be made to Holders of Securities under the Securities shall be given or made only to or
upon the order of the registered Holders of Securities (which shall be the Depositary or its
nominee in the case of a Global Security). The rights of beneficial owners in any Global
Securities shall be exercised only through the Depositary subject to the customary procedures of
the Depositary. The Trustee may rely and shall be fully protected in relying upon information
furnished by the Depositary with respect to its Agent Members.

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

24

 

     Section 2.12. Replacement Securities. If a mutilated Security is surrendered to the
Registrar or if the Securityholder of a Security claims that the Security has been lost, destroyed
or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the
Securityholder (i) notifies the Company or the Trustee within a reasonable time after he has
notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer
prior to receiving such notification, (ii) makes such request to the Company or the Trustee prior
to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform
Commercial Code (a “Protected Purchaser”) and (iii) satisfies any other reasonable requirements of
the Trustee and the Company. If required by the Trustee or the Company, such Securityholder shall
furnish an indemnity bond sufficient in the judgment of the Trustee to protect the Company, the
Trustee, the Paying Agent, the Conversion Agent and the Registrar from any loss that any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the Securityholder
for their expenses in replacing a Security. In case any Security which has matured or is about to
mature or has been called for redemption or has been properly tendered for repurchase on a
Fundamental Change Repurchase Date (and not withdrawn) or has been tendered for repurchase on a
Repurchase Date (and not withdrawn), as the case may be, or is to be converted into Common Stock,
shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Security, pay or authorize the payment of or convert or authorize the conversion of the
same (without surrender thereof except in the case of a mutilated Securities), as the case may be,
if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and,
if applicable, to such authenticating agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by or in connection
with such substitution, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent
evidence to their satisfaction of the destruction, loss or theft of such Securities and of the
ownership thereof.

     Every replacement Security is an additional obligation of the Company.

     The provisions of this Section 2.12 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Securities.

     Section 2.13. Outstanding Securities. Securities outstanding at any time are all Securities
authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section as not outstanding. A Security does not cease to
be outstanding because the Company or an Affiliate of the Company holds the Security.

25

 

     If a Security is replaced pursuant to Section 2.12, it ceases to be outstanding unless the
Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a
Protected Purchaser.

     If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a
Fundamental Change Redemption Date, Redemption Date, Repurchase Date or Maturity Date money
sufficient to pay all principal and
interest payable on that date with respect to the Securities (or portions thereof) to be
redeemed, repurchased or maturing, as the case may be, and the Paying Agent is not prohibited from
paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then
on and after that date such Securities (or portions thereof) cease to be outstanding and interest
on them ceases to accrue.

     Section 2.14. Temporary Securities. Pending the preparation of Securities in certificated
form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee
shall, upon the written request of the Company, authenticate and deliver temporary Securities
(printed or lithographed). Temporary Securities shall be issuable in any authorized denomination,
and substantially in the form of the Securities in certificated form, but with such omissions,
insertions and variations as may be appropriate for temporary Security, all as may be determined by
the Company. Every such temporary Security shall be executed by the Company and authenticated by
the Trustee or such authenticating agent upon the same conditions and in substantially the same
manner, and with the same effect, as the Securities in certificated form. Without unreasonable
delay, the Company will execute and deliver to the Trustee or such authenticating agent Securities
in certificated form and thereupon any or all temporary Securities may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the
Trustee or such authenticating agent shall authenticate and make available for delivery in exchange
for such temporary Securities an equal aggregate principal amount of Securities in certificated
form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the
same benefits and subject to the same limitations under this Indenture as Securities in
certificated form authenticated and delivered hereunder.

     Section 2.15. Cancellation. The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else
shall cancel all Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver canceled Securities to the Company pursuant to written direction by an
Officer. The Company may not issue new Securities to replace Securities it has redeemed, paid or
delivered to the Trustee for cancellation. The Trustee shall not authenticate Securities in place
of canceled Securities other than pursuant to the terms of this Indenture.

26

 

     Section 2.16. CUSIP and ISIN Numbers. The Company in issuing the Securities may use “CUSIP”
and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” and “ISIN”
numbers in notices of redemption as a convenience to Securityholders; provided that any such notice
may state that no representation is made as to the correctness of such numbers either as printed on
the Securities or as contained in any notice of a redemption and that reliance may be placed only
on the other identification numbers printed on the Securities,
and any such redemption shall not be affected by any defect in or omission of such numbers.

     Section 2.17. Additional Securities; Repurchases. The Company may, from time to time without
the consent of the Holders of outstanding Securities, increase the principal amount of the
Securities by issuing additional Securities in the future pursuant to this Indenture (“Additional
Securities”) having terms and conditions identical to those of the other outstanding Securities,
except that Additional Securities may have a different initial date from which interest begins to
accrue thereon so that the Additional Securities are fungible with outstanding Securities; provided
that if the Additional Securities are not fungible with the Securities for U.S. federal income tax
purposes, the Additional Securities will have a separate CUSIP number from the Securities; and
provided further, that the Additional Securities shall have the same CUSIP number as the Securities
issued pursuant to the Purchase Agreement. The Securities originally issued pursuant to the
Purchase Agreement and any Additional Securities shall be treated as a single class for all
purposes under this Indenture, including waivers, amendments, redemptions, offers to purchase and
United States federal tax purposes. No Additional Securities may be issued if on the issue date
therefor any Event of Default has occurred and is continuing. The Company may, to the extent
permitted by law, repurchase any Security in the open market or by tender offer at any price or by
private agreement. Any Security repurchased by the Company may, at the Company’s option, be
surrendered to the Trustee for cancellation, but may not be reissued or resold by the Company. Any
Security surrendered for cancellation may not be reissued or resold and will be promptly cancelled.

ARTICLE 3

Redemption and Repurchase of Securities

     Section 3.01. Optional Redemption of Securities. At any time on or after November 6, 2017,
the Securities may be redeemed at the option of the Company, in whole or in part, upon notice as
set forth in Section 3.02, in cash at the redemption price (the “Redemption Price”) equal to 100%
of the principal amount thereof plus accrued and unpaid interest to, but excluding the redemption
date (the “Redemption Date”); provided, however, if the Redemption Date is after an Interest Record
Date and on or prior to the corresponding Interest Payment Date, such interest will be paid on the
Redemption Date to the Holder of

27

 

record on such Interest Record Date. The Company may not redeem
any Securities if the principal amount of the Securities has been accelerated (other than as a
result of a failure to pay the relevant Redemption Price), and such acceleration has not been
rescinded, on or prior to the relevant Redemption Date.

     Section 3.02. Notice of Optional Redemption; Selection of Securities to be Redeemed. If the
Company shall desire to exercise the right to redeem all or, as the case may be, any part of the
Securities pursuant to Section 3.01, it shall fix a date for redemption and it or, at its written
request received by the Trustee not
fewer than five Business Days prior (or such shorter period of time as may be acceptable to
the Trustee) to the date the notice of redemption is to be mailed, the Trustee in the name of and
at the expense of the Company, shall mail or cause to be mailed a notice of such redemption not
less than 25 Scheduled Trading Days nor more than 60 Business Days prior to the Redemption Date to
each Holder of Securities so to be redeemed in whole or in part at its last address as the same
appears on the Register of the Registrar; provided that if the Company makes such request of the
Trustee, the Company shall provide the Trustee with the text of the notice of redemption and shall
give written notice of the Redemption Date to the Trustee. Such mailing shall be by first class
mail. The notice, if mailed in the manner herein provided, shall be conclusively presumed to have
been duly given, whether or not the Holder receives such notice. In any case, failure to give such
notice by mail or any defect in the notice to the Holder of any Securities designated for
redemption as a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Securities.

     Each such notice of redemption shall specify: (i) the aggregate principal amount of Securities
to be redeemed, (ii) the CUSIP number or numbers of the Securities being redeemed, (iii) the
Redemption Date (which shall be a Business Day), (iv) the Redemption Price at which Securities are
to be redeemed, (v) the place or places of payment and that payment will be made upon presentation
and surrender of such Securities, (vi) that interest accrued and unpaid to, but excluding, the
Redemption Date will be paid as specified in said notice, and that on and after said date interest
thereon or on the portion thereof to be redeemed will cease to accrue, (vii) that the Holder has a
right to convert the Securities called for redemption, (viii) the Conversion Rate on the date of
such notice, (ix) the time and date on which the right to convert such Securities or portions
thereof will expire and (x) the formula for determining the amount of cash and the number of
shares, if any, to be delivered to the Holder upon conversion pursuant to Section 10.13 and the
date on which the Conversion Observation Period begins. If fewer than all the Securities are to be
redeemed, the notice of redemption shall identify the Securities to be redeemed (including CUSIP
numbers, if any). If any Securities are to be redeemed in part only, the notice of redemption
shall state the portion of the principal amount thereof to be redeemed and shall state that, on and
after the Redemption Date, upon surrender of such Securities, a new Security or

28

 

Securities in
principal amount equal to the unredeemed portion thereof will be issued.

     Whenever any Securities are to be redeemed, the Company will give the Trustee written notice
of the Redemption Date, together with an Officers’ Certificate as to the aggregate principal amount
of Securities to be redeemed not fewer than 30 Scheduled Trading Days (or such shorter period of
time as may be acceptable to the Trustee) prior to the Redemption Date.

     On or prior to the Redemption Date specified in the notice of redemption given as provided in
this Section 3.02, the Company will deposit with the Paying Agent (or, if the Company is acting as
its own Paying Agent, set aside, segregate
and hold in trust as provided in Section 2.06) an amount of money in immediately available
funds sufficient to redeem on the Redemption Date all the Securities (or portions thereof) so
called for redemption (other than those theretofore surrendered for conversion) at the appropriate
Redemption Price, together with accrued and unpaid interest to, but excluding, the Redemption Date;
provided that if such payment is made on the Redemption Date, it must be received by the Paying
Agent, by 11:00 a.m., New York City time, on such date. If any Securities called for redemption
are converted pursuant hereto prior to such Redemption Date, any money deposited with the Paying
Agent or so segregated and held in trust for the redemption of such Securities shall be paid to the
Company or, if then held by the Company, shall be discharged from such trust.

     If less than all of the outstanding Securities are to be redeemed, the Trustee shall select
the Securities or portions thereof of the Global Securities or the Securities in certificated form
to be redeemed (in principal amounts of $1,000 or integral multiples thereof) by lot, on a pro rata
basis or by another method the Trustee deems fair and appropriate (and in such manner as complies
with applicable legal requirements). If any Security selected for redemption is submitted for
conversion in part after such selection, the portion of such Securities submitted for conversion
shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The
Securities (or portions thereof) so selected for redemption shall be deemed duly selected for
redemption for all purposes hereof, notwithstanding that any such Securities are submitted for
conversion in part before the mailing of the notice of redemption.

     Upon any redemption of less than all of the outstanding Securities, the Company and the
Trustee may (but need not), solely for purposes of determining the pro rata allocation among such
Securities that are unconverted and outstanding at the time of redemption, treat as outstanding any
Securities surrendered for conversion during the period of 15 calendar days preceding the mailing
of a notice of redemption and may (but need not) treat as outstanding any Securities authenticated
and delivered during such period in exchange for the unconverted portion of any Securities
converted in part during such period.

29

 

     Section 3.03. Payment of Securities Called for Redemption. Unless the Company shall default
in the payment of such Securities at the Redemption Price, plus interest, if any, accrued and
unpaid to, but excluding, the applicable Redemption Date, interest on the Securities or portion of
Securities so called for redemption, shall cease to accrue on and after such date and, after 5:00
p.m., New York City time, on the Business Day immediately preceding the Redemption Date (unless the
Company shall default in the payment of such Securities at the Redemption Price, together with
interest accrued to such date) such Securities shall cease to be convertible and, except as
provided in Section 2.06 and Section 8.02, to be entitled to any benefit or security under this
Indenture, and the Holders thereof shall have no right in respect of such Securities except the
right to receive the Redemption Price thereof plus accrued and unpaid interest to, but excluding,
the Redemption Date. On presentation and surrender of such Securities at a place
of payment in said notice specified, the said Securities or the specified portions thereof
shall be paid and redeemed by the Company at the Redemption Price, together with interest accrued
and unpaid thereon to, but excluding, the Redemption Date.

     If on the Redemption Date the Paying Agent holds, in accordance with the terms hereof, cash
sufficient to pay the Redemption Price and related accrued interest, of any Security to be redeemed
on the Redemption Date in accordance with this Indenture then, on the Redemption Date such Security
will cease to be outstanding, whether or not book-entry transfer of the Security has been made or
the Security is delivered to the Paying Agent, as the case may be, and interest, shall cease to
accrue, and the rights of the Holder in respect of the Security shall terminate (other than the
right to receive the Redemption Price as aforesaid upon delivery or transfer of the Securities in
accordance with this Indenture).

     Upon presentation of any Securities redeemed in part only, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of
the Company, a new Security or Securities of authorized denominations, in principal amount equal to
the unredeemed portion of the Securities so presented.

     Notwithstanding the foregoing, the Trustee shall not redeem any Securities or mail any notice
of redemption if the principal amount of the Securities has been accelerated (other that as a
result to pay the relevant Redemption Price), and such acceleration has not been rescinded, on or
prior to the relevant Redemption Date. If any Securities called for redemption shall not be so
paid upon surrender thereof for redemption on the Redemption Date as provided in this Section 3.03,
to the extent legally permissible, the Redemption Price shall, until paid or duly provided for,
bear interest from and including the Redemption Date at the interest rate borne by the Securities
and such Securities shall remain convertible into Common Stock until the Redemption Price and
interest shall have been paid or duly provided for.

30

 

     Section 3.04. Repurchase at Option of Holders Upon a Fundamental Change. (a) If there shall
occur a Fundamental Change at any time prior to the Maturity Date, then each Holder of Securities
shall have the right, at such Holder’s option, to require the Company to repurchase, at the
Fundamental Change Repurchase Price (as defined below), all of such Holder’s Securities, or any
portion thereof that is a multiple of $1,000 principal amount, on a date (the “Fundamental Change
Repurchase Date”) specified by the Company, that is not less than 20 Business Days nor more than 35
Business Days after the date of the Company Repurchase Notice related to such Fundamental Change at
a cash repurchase price equal to 100% of the principal amount of the Securities being repurchased,
plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date (the
“Fundamental Change Repurchase Price”), subject to the satisfaction by the Holder of the
requirements set forth in Section 3.04(c); provided that if such Fundamental Change Repurchase Date
falls after an
Interest Record Date and on or prior to the corresponding interest payment date, then the
interest payable on the Fundamental Change Repurchase Date shall be paid on the Fundamental Change
Repurchase Date to the Holders of record of the Securities on the applicable Interest Record Date
instead of the Holders surrendering the Securities for repurchase on such date.

     (b) On or before the 15th calendar day after the occurrence of a Fundamental Change, the
Company will provide to the Trustee and to all Holders of record of the Securities on the date of
the Fundamental Change at their addresses shown in the Register of the Registrar and to beneficial
owners of the Securities to the extent required by applicable law, the Company Repurchase Notice as
set forth in Section 3.06 with respect to such Fundamental Change.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
repurchase rights of Holders of Securities or affect the validity of the proceedings for the
repurchase of the Securities pursuant to this Section 3.04.

     (c) For Securities to be repurchased at the option of the Holder, the Holder must deliver to
the Paying Agent, prior to 5:00 p.m., New York City time, on the Fundamental Change Repurchase
Date, (i) a written notice to the Paying Agent of exercise of repurchase (the “Fundamental Change
Repurchase Notice”) in the form set forth on the reverse of the Securities duly completed (if the
Securities are certificated) or comply with applicable Depositary procedures (if the Securities are
represented by a Global Security), together with (ii) such Securities duly endorsed for transfer
(if the Securities are certificated) or book-entry transfer of such Securities (if the Securities
are represented by a Global Security). The delivery of such Securities to the Paying Agent with,
or at any time after delivery of, the Fundamental Change Repurchase Notice (together with all
necessary endorsements) at the office of the Paying Agent shall be a condition to payment by the
Company to the Holder of the Fundamental Change Repurchase Price therefor; provided that such
Fundamental Change Repurchase

31

 

Price shall be so paid pursuant to this Section 3.04 only if the
Securities so delivered to the Paying Agent shall conform in all respects to the description
thereof in the Fundamental Change Repurchase Notice. All questions as to the validity, eligibility
(including time of receipt) and acceptance of any Securities for repurchase shall be determined by
the Company, whose determination shall be final and binding absent manifest error.

     (d) The Company shall repurchase from the Holder thereof, pursuant to this Section 3.04, a
portion of a Security, if the principal amount of such portion is $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to the repurchase of all of a Security also apply
to the repurchase of such portion of such Security.

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

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.04
shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Fundamental Change Repurchase Date and the time of the book-entry
transfer or delivery of the Securities.

     Section 3.05. Repurchase of Securities by the Company at the Option of Holders. (a) Each
Holder of Securities shall have the right, at such Holder’s option, to require the Company to
repurchase all of such Holder’s Securities, or any portion thereof that is a multiple of $1,000
principal amount, on November 1, 2017, November 1, 2021 and November 1, 2026 (each, a “Repurchase
Date”), at a repurchase price of 100% of the principal amount of the Securities being repurchased,
plus accrued and unpaid interest to, but excluding, the Repurchase Date (the “Repurchase Price”).
However, if such Repurchase Date falls after an Interest Record Date and on or prior to the
corresponding interest payment date, then the interest payable on such interest payment date shall
be paid on the Repurchase Date to the Holders of record of the Securities on the applicable
Interest Record Date instead of the Holders surrendering the Securities for repurchase on such
date.

     (b) On or before the 20th Business Day prior to each Repurchase Date, the Company shall mail
or cause to be mailed to all Holders of record on such date at their addresses shown in the
Register of the Registrar (and to beneficial owners as required by applicable law) a Company
Repurchase Notice as set forth in Section 3.06.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
repurchase rights of Holders of Securities or affect the

32

 

validity of the proceedings for the
repurchase of the Securities pursuant to this Section 3.05.

     (c) For Securities to be so repurchased at the option of the Holder, the Holder must deliver
to the Paying Agent, at any time during the period beginning at 9:00 a.m., New York City time, on
the date that is 20 Business Days prior to the applicable Repurchase Date and ending at 5:00 p.m.,
New York City time, on the Business Day immediately preceding the applicable Repurchase Date, (i) a
notice (the “Repurchase Notice”) in the form set forth on the reverse of the Securities duly
completed (if the Securities are certificated) or comply with applicable Depositary procedures (if
the Securities are represented by a Global Security) together with (ii) such Securities duly
endorsed for transfer (if the Securities are certificated) or book-entry transfer of such
Securities (if such Securities are represented by a Global Security). The delivery of such
Securities to the Paying Agent with, or at any time after delivery of, the Repurchase Notice
(together with all necessary endorsements) at the office of the Paying Agent shall be a
condition to the payment by the Company to the Holder of the repurchase price therefor; provided
that such repurchase price shall be so paid pursuant to this Section 3.05 only if the Securities so
delivered to the Paying Agent shall conform in all respects to the description thereof in the
Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and
acceptance of any Securities for repurchase shall be determined by the Company, whose determination
shall be final and binding absent manifest error.

     (d) The Company shall repurchase from the Holder thereof, pursuant to this Section 3.05, a
portion of a Security, if the principal amount of such portion is $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to the repurchase of all of a Security also apply
to the repurchase of such portion of such Securities.

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

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.05
shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Repurchase Date and the time of the book-entry transfer or delivery of
the Securities, as the case may be.

     Section 3.06. Company Repurchase Notice; Tender Offer Compliance. (a) In connection with any
repurchase of Securities, the Company shall, in the case of a Fundamental Change, on or before the
15th calendar day after the occurrence of such Fundamental Change or, no less than 20 Business Days
prior to each Repurchase Date, give notice to Holders (with a copy to the Trustee) setting forth
information specified in this Section 3.06 (in either case, the “Company Repurchase Notice”).

33

 

     Each Company Repurchase Notice shall:

     (1) state the Repurchase Price or the Fundamental Change Repurchase Price, as applicable, and
the Fundamental Change Repurchase Date or the Repurchase Date, as applicable, to which the Company
Repurchase Notice relates;

     (2) state, if applicable, the circumstances constituting the Fundamental Change;

     (3) state that the Repurchase Price or the Fundamental Change Repurchase Price, as applicable,

City time, on the Fundamental Change Repurchase Date or on the Business Day immediately preceding
the Repurchase Date, as the case may be;

     (5) include a form of Repurchase Notice or Fundamental Change Repurchase Notice, as
applicable;

     (6) state the name and address of the Paying Agent;

     (7) state that Securities must be surrendered to the Paying Agent to collect the repurchase
price;

     (8) state that a Holder may withdraw its Repurchase Notice or Repurchase Notice or Fundamental
Change Repurchase Notice, as applicable, at any time prior to 5:00 p.m., New York City time, on the
Business Day immediately preceding the Repurchase Date or the Fundamental Change Repurchase Date,
as the case may be, by delivering a valid written notice of withdrawal in accordance with Section
3.07;

     (9) state whether the Securities are then convertible, the then applicable Conversion Rate,
including, in the case of the occurrence of a Fundamental Change, expected changes, if any, in the
Conversion Rate resulting from such Fundamental Change transaction and expected changes in the
cash, shares or other property deliverable upon conversion of the Securities as a result of the
occurrence of the Fundamental Change;

     (10) that Securities as to which a Fundamental Change Repurchase Notice has been given may be
converted only if the Fundamental Change Repurchase Notice is withdrawn in accordance with the
terms of this Indenture;

     (11) state the amount of interest accrued and unpaid per $1,000 principal amount of Securities
to, but excluding, the Fundamental Change Repurchase Date or Repurchase Date, as the case may be;
and

34

 

     (12) state the CUSIP number of the Securities.

A Company Repurchase Notice may be given by the Company or, at the Company’s request, the Trustee
shall give such Company Repurchase Notice in the Company’s name and at the Company’s expense;
provided that the text of the Company Repurchase Notice shall be prepared by the Company.

     (b) The Company will, to the extent applicable: (i) comply with the provisions of Rule 13e-4
and Rule 14e-1 (or any successor provision) under the Exchange Act that may be applicable at the
time of the repurchase of the Securities, (ii) file the related Schedule TO (or any successor
schedule, form or report) under the Exchange Act or any other schedule required in connection with
any offer by the Company to repurchase the Securities and (iii) comply with all other federal and
state securities laws in connection with any offer by the Company to repurchase the Securities.

     Section 3.07. Effect of Repurchase Notice; Withdrawal. Upon receipt by the Paying Agent of
the Fundamental Change Repurchase Notice specified in
Section 3.04 or of the Repurchase Notice specified in Section 3.05, as applicable, the Holder
of the Securities in respect of which such Fundamental Change Repurchase Notice or Repurchase
Notice, as applicable, was given shall (unless such Fundamental Change Repurchase Notice or the
Repurchase Notice, as applicable, is validly withdrawn in accordance with the following paragraph)
thereafter be entitled to receive solely the repurchase price with respect to such Securities.
Such repurchase price shall be paid to such Holder, subject to receipt of funds and/or the
Securities by the Paying Agent, promptly following the later of (x) the Fundamental Change
Repurchase Date or Repurchase Date, as applicable, with respect to such Securities (provided the
Holder has satisfied the conditions in Section 3.04 or Section 3.05, as applicable) and (y) the
time of book-entry transfer or delivery of such Securities to the Paying Agent by the Holder
thereof in the manner required by Section 3.04 or Section 3.05, as applicable. The Securities in
respect of which a Fundamental Change Repurchase Notice or a Repurchase Notice, as applicable, has
been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the
date of the delivery of such Fundamental Change Repurchase Notice or such Repurchase Notice, as
applicable, unless such Fundamental Change Repurchase Notice or such Repurchase Notice, as
applicable, has first been validly withdrawn.

     A Fundamental Change Repurchase Notice or Repurchase Notice, as applicable, may be withdrawn
by means of a written notice of withdrawal delivered to the office of the Paying Agent in
accordance with the Fundamental Change Repurchase Notice or the Repurchase Notice, as applicable,
at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be, specifying:

35

 

     (a) the certificate number, if any, of the Securities in respect of which such notice of
withdrawal is being submitted if they are in certificated form, or the appropriate Depositary
information, in accordance with appropriate Depositary procedures, if the Securities in respect of
which such notice of withdrawal is being submitted is represented by a Global Security,

     (b) the principal amount of the Securities with respect to which such notice of withdrawal is
being submitted, and

     (c) the principal amount, if any, of such Securities which remains subject to the original
Fundamental Change Repurchase Notice or the Repurchase Notice, as applicable, which shall be $1,000
or a whole multiple of $1,000.

     If a Fundamental Change Repurchase Notice or Repurchase Notice, as applicable, is properly
withdrawn, the Company shall not be obligated to repurchase the Securities listed in such
Fundamental Change Repurchase Notice or Repurchase Notice, as applicable.

     Section 3.08. Deposit of Repurchase Price or Fundamental Change Repurchase Price. Prior to
11:00 a.m., New York City time, on the Fundamental Change Repurchase Date or the Repurchase Date,
as applicable, the Company shall deposit with the Paying Agent or, if the Company is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 2.06, an amount of cash (in
immediately available funds if deposited on the Fundamental Change Repurchase Date or the
applicable Repurchase Date, as the case may be), sufficient to pay the aggregate repurchase price
of all the Securities or portions thereof that are to be repurchased as of the Fundamental Change
Repurchase Date or the Repurchase Date, as the case may be.

     If on the Fundamental Change Repurchase Date or a Repurchase Date the Paying Agent holds cash
sufficient to pay the repurchase price and related accrued interest of the Securities that Holders
have elected to require the Company to repurchase in accordance with Section 3.04 or 3.05, as the
case may be, then, on the Fundamental Change Repurchase Date or the applicable Repurchase Date, as
the case may be, such Securities will cease to be outstanding, and interest will cease to accrue
(whether or not book entry transfer or delivery of the Securities has been made to the Paying
Agent) and all other rights of the Holders of such Securities will terminate, other than the right
to receive the repurchase price and any accrued interest upon delivery or book-entry transfer of
the Securities. This will be the case whether or not book-entry transfer of the Securities has
been made or the Securities has been delivered to the Paying Agent.

     Section 3.09. Securities Repurchased in Part. Upon presentation of any Securities
repurchased only in part, the Company shall execute and the Trustee shall authenticate and make
available for delivery to the Holder thereof, at the expense of the Company, a new Security or
Securities, of any authorized

36

 

denomination, in aggregate principal amount equal to the unrepurchased portion of the
Securities presented.

ARTICLE 4

Covenants

     Section 4.01. Payment of Securities. The Company shall promptly pay the principal of and
interest on the Securities on the dates and in the manner provided in the Securities and in this
Indenture in each such case, prior to 11:00 a.m., New York City time. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying Agent holds in
accordance with this Indenture money sufficient to pay all principal and interest then due and the
Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture.

     Section 4.02. Maintenance of Office or Agency. The Company will maintain an office or agency
in the United States where the Securities may be surrendered for registration of transfer or
exchange or for presentation for payment or for conversion, redemption or repurchase and where
notices and demands to or upon the Company in respect of the Securities and this Indenture may be
served. As of the date of this Indenture, such office is located at the office of the Trustee
located at 100 Wall Street, Suite 1600, New York, NY 10005 and, at any other time, at such other
address as the Trustee may designate from time to time by notice to the Company. The Company will
give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency not designated or appointed by the Trustee. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office.

     The Company may also from time to time designate co-registrars and one or more offices or
agencies where the Securities may be presented or surrendered for any or all such purposes and may
from time to time rescind such designations. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such other
office or agency.

     Section 4.03. Rule 144A Information Requirement and Annual Reports.

     (a) The Company covenants and agrees that it shall, during any period in which it is not
subject to Section 13 or 15(d) under the Exchange Act, make available to any holder or beneficial
holder of Securities or any Common Stock issued upon conversion thereof which continue to be
Restricted Securities and any prospective purchaser of Securities or such Common Stock designated
by such

37

 

holder or beneficial holder, the information required pursuant to Rule 144A(d)(4)
under the Securities Act upon the request of any holder or beneficial holder of the Securities
or such Common Stock, all to the extent required to enable such holder or beneficial holder to sell
its Securities or Common Stock without registration under the Securities Act within the limitation
of the exemption provided by Rule 144A. The Company shall take such further action as any holder or
beneficial holder of Securities or such Common Stock may reasonably request to the extent required
from time to time to enable such holder or beneficial owner to sell such Securities or shares of
Common Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended
from time to time.

     (b) The Company shall file with the Trustee within 15 days after the same are required to be
filed with the Commission, copies of any documents or reports that the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace
period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the
Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed
with the Trustee for purposes of this Section Section 4.03(b) at the time such documents are filed
via the EDGAR system.

     (c) Delivery of the reports and documents listed in subsection (b) above to the Trustee is for
informational purposes only, and the Trustee’s receipt of such reports and documents shall not
constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate).

     (d) If, at any time during the six-month period beginning on, and including, the date that is
six months after the Last Original Issuance Date, the Company fails to timely file any document or
report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and
other than reports on Form 8-K), or the Securities are not otherwise freely tradable by Holders
other than the Company’s Affiliates (as a result of restrictions pursuant to U.S. securities law or
the terms of this Indenture or the Securities), the Company shall pay Additional Interest on the
Securities. Such Additional Interest shall accrue on the Securities initially at a rate of 0.25%
per annum and, beginning on the 91st day immediately following the first day the Company fails to
file such information or such Securities are not otherwise freely tradeable, at a rate of 0.50% per
annum, in each case of the principal amount of Securities outstanding on each day during such
periods for which the Company’s failure to file has occurred and is continuing or the Securities
are not freely tradable. As used in this Section 4.03(d), documents or reports that the Company is
required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does

38

 

not
include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or
15(d) of the Exchange Act.

     (e) If, and for so long as, the restrictive legend on the Securities specified in Section
2.10(a) has not been removed, the Securities are assigned a restricted CUSIP or the Securities are
not otherwise freely tradable by Holders other than the Company’s Affiliates (without restrictions
pursuant to U.S. securities law or the terms of this Indenture or the Securities) as of the Free
Trade Date, the Company shall pay Additional Interest on the Securities at a rate equal to 0.50%
per annum of the principal amount of Securities outstanding until the restrictive legend on the
Securities has been removed in accordance with Section 2.10(a) and the Securities are freely
tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S.
securities law or the terms of this Indenture or the Securities).

     (f) Additional Interest will be payable in arrears on each Interest Payment Date following
accrual in the same manner as regular interest on the Securities.

     (g) The Additional Interest that is payable in accordance with Section 4.03(d) and Section
4.03(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as
a result of the Company’s election pursuant to Section 6.13.

     Section 4.04. Existence. Subject to Article 5, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and rights (charter
and statutory); provided that the Company shall not be required to preserve any such right if the
Company shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any material respect to
the Holders of Securities.

     Section 4.05. Payment of Taxes and Other Claims. The Company will pay or discharge, or cause
to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Significant Subsidiary or upon the
income, profits or property of the Company or any Significant Subsidiary, (ii) all claims for
labor, materials and supplies which, if unpaid, might by law become a lien or charge upon the
property of the Company or any Significant Subsidiary and (iii) all stamp taxes and other duties,
if any, which may be imposed by the United States or any political subdivision thereof or therein
in connection with the issuance, transfer, exchange, conversion, redemption or repurchase of any
Securities or with respect to this Indenture; provided that, in the case of clauses (i) and (ii),
the Company shall not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim (A) if the failure to do so will not, in the aggregate, have a
material adverse impact on the Company, or (B)

39

 

if the amount, applicability or validity is being
contested in good faith by appropriate proceedings.

     Section 4.06. Compliance Certificate. The Company shall deliver to the Trustee within 120
days after the end of each fiscal year of the Company an Officers’ Certificate stating, as to each
such Officer signing such certificate, whether to such Officer’s knowledge the Company during such
preceding fiscal year has kept, observed, performed and fulfilled the covenants contained in this
Indenture and, if the Company shall be in Default, the certificate shall describe the Default, its
status and what action the Company is taking or proposes to take with respect thereto. The Company
also shall comply with Section 314(a)(4) of the TIA.

     Section 4.07. Additional Interest Notice. If the Company is required to pay Additional
Interest to Holders of Securities pursuant to Section 4.03(d), Section 4.03(e) or Section 6.13, the
Company will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation
to pay Additional Interest no later than two Business Days prior to the proposed payment date for
Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional
Interest to be paid by the Company on such payment date. The Trustee shall not at any time be
under any duty or responsibility to any Holder of Securities to determine the Additional Interest,
or with respect to the nature, extent or calculation of the amount of Additional Interest when
made, or with respect to the method employed in such calculation of the Additional Interest.

ARTICLE 5

Successor Company

     Section 5.01. When Company May Merge or Transfer Assets. The Company shall not in a single
transaction or a series of related transactions consolidate with or merge with or into any other
Person (other than a Subsidiary of the Company), or sell, convey, transfer or lease its property
and assets substantially as an entirety to any Person (other than to one or more of the
Subsidiaries of the Company as an entirety or substantially as an entirety), unless:

     (a) either (i) the Company is the continuing corporation, or (ii) the resulting, surviving or
transferee person (if other than the Company) is a corporation or limited liability company
organized and existing under the laws of the United States, any state thereof or the District of
Columbia and such person assumes, by a supplemental indenture in a form reasonably satisfactory to
the Trustee, all of the Company’s obligations under the Securities and this Indenture;

     (b) immediately after giving effect to the transaction described above, no Default or Event of
Default, has occurred and is continuing;

40

 

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

     (d) the Company has delivered to the Trustee the Officers’ Certificate and Opinion of Counsel,
if any, requested by the Trustee pursuant to this Indenture.

     Section 5.02. Successor to be Substituted. In case of any such consolidation, merger, sale,
conveyance, transfer or lease in which the Company is not the continuing corporation and upon the
assumption by the successor Person, by supplemental indenture, executed and delivered to the
Trustee and reasonably satisfactory in form and substance to the Trustee, of the due and punctual
payment of the principal of, and interest on all of the Securities, and the due and punctual
performance and observance of all of the covenants and conditions of this Indenture to be performed
or satisfied by the Company, such successor Person shall succeed to and be substituted for the
Company, with the same effect as if it had been named herein as a party hereto, and the Company
shall be discharged from its obligations under the Securities and this Indenture. Such successor
Person thereupon may cause to be signed, and may issue the Securities either in its own name or in
the name of the Company.

     Upon the order of such successor Person instead of the Company and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall
deliver, or cause to be authenticated and delivered, any Securities that previously shall have been
signed and delivered by the officers of the Company to the Trustee for authentication, and any
Securities that such successor Person thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Securities had been issued at the
date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance,
transfer or lease, upon compliance with this Article 5 the Person named as the “Company” in the
first paragraph of this Indenture or any successor that shall thereafter have become such in the
manner prescribed in this Article 5 may be dissolved, wound up and liquidated at any time
thereafter and such Person shall be discharged from its liabilities as obligor and maker of the
Securities and from its obligations under this Indenture.

     Section 5.03. Opinion of Counsel to be Given to Trustee. Prior to execution of any
supplemental indenture pursuant to this Article 5, if so requested by the Trustee, the Trustee
shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any
such consolidation, merger, sale,

41

 

conveyance, transfer or lease and any such assumption complies
with the provisions of this Article 5.

ARTICLE 6

Defaults and Remedies

     Section 6.01. Events of Default. An “Event of Default” occurs if:

     (a) the Company defaults in any payment of interest on any Security when the same becomes due
and payable and such default continues for a period of 30 calendar days;

     (b) the Company defaults in the payment of the principal of any Security when the same becomes
due and payable at maturity, or the Company defaults in the payment of the Redemption Price, the
Fundamental Change Repurchase Price or the Repurchase Price, in each case when due;

     (c) the Company fails to deliver cash and, if applicable, shares of Common Stock (including
any Additional Shares), or a combination of the foregoing, as required pursuant to Article 10 upon
the conversion of any Securities and such failure continues for five Business Days following the
scheduled settlement date for such conversion;

     (d) the Company fails to provide notice of the anticipated effective date or actual effective
date of a Fundamental Change on a timely basis as required in this Indenture;

     (e) the Company fails to perform or observe any other term, covenant or agreement contained in
the Securities or this Indenture (other than those referred to in (a), (b), (c) or (d) above) and
such failure continues for 60 days after receipt by the Company of a Notice of Default;

     (f) a failure to pay when due (whether at stated maturity or otherwise) by the Company or any
Significant Subsidiary of the Company, after the expiration of any applicable grace period, of
principal of or interest on indebtedness for borrowed money, where the amount of such unpaid
principal and/or interest is in an aggregate amount in excess of $50 million or more (or a foreign
currency equivalent), or a default that results in the acceleration of maturity, of any
indebtedness for borrowed money of the Company or any Significant Subsidiary of the Company in an
aggregate amount in excess of $50 million (or its foreign currency equivalent at the time), in each
case, if both (i) such Indebtedness is not discharged and (ii) such acceleration is not rescinded,
stayed or annulled, within a period of 30 calendar days after receipt by the Company of a Notice of
Default;

42

 

     (g) a final judgment for the payment of $50 million or more (excluding any amounts covered by
insurance or subject to a binding indemnity from a financially responsible third party with
resources sufficient to pay such indemnity obligation when due) rendered against the Company or any
Significant Subsidiary of the Company, which judgment is not discharged or stayed within 90 days
after
(i) the date on which the right to appeal thereof has expired if no such appeal has commenced,
or (ii) the date on which all rights to appeal have been extinguished;

     (h) the Company or any Significant Subsidiary of the Company pursuant to or within the meaning
of any Bankruptcy Law:

     (i) commences a voluntary case;

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

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

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

or takes any comparable action under any foreign laws relating to insolvency;

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

     (i) is for relief against the Company or any Significant Subsidiary of the Company in
an involuntary case;

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

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

or any similar relief is granted under any foreign laws, and, in each such case, the order or
decree remains unstayed and in effect for 60 consecutive days.

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

     The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal
or state law for the relief of debtors. The term “Custodian” means any receiver, trustee,
assignee, liquidator, custodian or similar official under any Bankruptcy Law.

43

 

     A Default under clause (e) or (f) above is not an Event of Default until the Trustee or the
Securityholders of at least 25% in aggregate principal amount of the outstanding Securities notify
the Company or the Company and the Trustee, respectively, of the Default and the Company does not
cure such Default within the time specified after receipt of such notice. Such notice must specify
the
Default, demand that it be remedied and state that such notice is a “Notice of Default.” When
any Default under this Section 6.01 is cured in accordance herewith, it shall cease to be a
Default.

     The Company shall deliver to the Trustee, promptly upon becoming aware of any Default, written
notice in the form of an Officers’ Certificate of any Default known to the party, its status and
what action the Company is taking or proposes to take with respect thereto.

     Section 6.02. Acceleration. If an Event of Default (other than an Event of Default specified
in Section 6.01(h) or Section 6.01(i) with respect to the Company) occurs and is continuing, the
Trustee by written notice to the Company, or the Securityholders of at least 25% in principal
amount of the outstanding Securities by written notice to the Company and the Trustee, may declare
the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable immediately. If an Event
of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company occurs, the
principal of and interest on all the Securities shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any Securityholders.
The Securityholders of a majority in principal amount of the Securities by notice to the Trustee
may rescind an acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if (i) the Company has paid (or deposited with the Trustee) all overdue
interest on all the Securities and the principal amount of the Securities that has become due
otherwise than by such acceleration or declaration, as well as paid interest upon overdue interest
to the extent that payment of such interest is lawful and paid to the Trustee any amount due to it
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and (ii) all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of acceleration. No such
rescission shall affect any subsequent Default or impair any right consequent thereto.

     Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, and the
principal of and accrued but unpaid interest on the Securities has been declared due and payable as
provided in Section 6.02 the Trustee may pursue any available remedy to collect the payment of
principal of or interest on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

44

 

     The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any
Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy
is exclusive of any other remedy. All available remedies are cumulative.

     Section 6.04. Waiver of Defaults and Events of Default. The Holders of a majority in
principal amount of the Securities outstanding by notice to the Trustee may on behalf of the
Holders of all the Securities, waive any Default or Event of Default and its consequences except
(i) a default in the payment of the principal of or interest on a Security when due, (ii) an Event
of Default arising from the failure to redeem or repurchase any Security when required pursuant to
the terms of this Indenture, (iii) an Event of Default arising from the failure of the Company to
deliver, cash and, if applicable, shares of Common Stock upon the conversion of any Securities
pursuant to the terms of this Indenture or (iv) a default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Securityholder affected. When an Event
of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or
other Event of Default or impair any consequent right.

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

     Section 6.06. Limitation on Suits. Except to enforce the right to receive payment of
principal or interest when due, no Securityholder may pursue any remedy with respect to this
Indenture or the Securities unless:

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

     (b) the Securityholders of at least 25% in principal amount of the Securities make a written
request to the Trustee to pursue the remedy;

45

 

     (c) such Securityholder or Securityholders offer to the Trustee security or indemnity
reasonably satisfactory to the Trustee against any loss, liability or expense of the Trustee;

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

     (e) the Securityholders of a majority in principal amount of the Securities do not give the
Trustee a direction inconsistent with the request.

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

     Anything contained in this Indenture or the Securities to the contrary notwithstanding, the
Holder of any Securities, without the consent of either the Trustee or the Holder of any other
Securities, on its own behalf and for its own benefit, may enforce, and may institute and maintain
any proceeding suitable to enforce, its rights of conversion as provided herein.

     Section 6.07. Rights of Securityholders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Securityholder to receive payment of the principal of
(including the Redemption Price, Fundamental Change Repurchase Price or Repurchase Price) and
accrued interest on the Securities held by such Securityholder, or delivery of the cash and, if
applicable, shares of Common Stock issuable upon conversion of the Securities, on or after the
respective due dates expressed in the Securities, or to bring suit for the enforcement of any such
payment or delivery on or after such respective dates, shall not be impaired or affected without
the consent of such Securityholder.

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section
6.01(a) or 6.01(b) occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount then due and owing
(together with interest on any unpaid interest to the extent lawful) and the amounts provided for
in Section 7.07.

     Section 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, their
creditors or their property and, unless prohibited by law or applicable regulations, may vote on
behalf of the Securityholders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each
Securityholder to make payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Securityholders, to pay to the Trustee any amount due
it

46

 

for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

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

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

     SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and
interest, ratably without preference or priority of any kind, according to the amounts due and
payable on the Securities for principal and interest, respectively; and

     THIRD: to the Company.

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

     Section 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court in its discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by the Trustee, a suit by a Securityholder pursuant to Section
6.07 or a suit by Securityholders of more than 10% in principal amount of the Securities or to any
suit instituted by any Holder of Securities for the enforcement of the payment of the principal of
or interest on any Securities on or after the due date expressed in such Securities or to any suit
for the enforcement of the right to convert any Securities in accordance with the provisions of
Article 10.

     Section 6.12. Waiver of Stay, Extension or Usury Laws. The Company (to the extent it may
lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such power as though no
such law had been enacted.

47

 

     Section 6.13. Alternative Remedy for Failure to Comply with Reporting Obligations in the
Indenture and TIA. Notwithstanding any other provision of this Article 6, if the Company so
elects, the sole remedy for an Event of Default relating to the failure to comply with Section 4.03
of this Indenture will consist exclusively of the right to receive additional interest (the
“Default Additional Interest”) on the Securities at a rate equal to (x) 0.25% per annum of the
principal amount of the Securities outstanding for each day during the 90-day period on which such
Event of Default is continuing beginning on, and including, the date on which such Event of Default
first occurs and (y) 0.50% per annum of the principal amount of the Securities outstanding for each
day during the 275-day period beginning on, and including, the 91st day on which such Event of
Default is continuing (in addition to any Additional Interest that may accrue pursuant to Section
4.03(d) or Section 4.03(e)). In the event the Company does not elect to pay the Default Additional
Interest upon an Event of Default in accordance with this Section 6.13, the Securities will be
subject to acceleration as provided above. The Default Additional Interest will accrue on all
outstanding Securities from and including the date on which an Event of Default relating to a
failure to comply with Section 4.03 of this Indenture first occurs to, but not including, the 365th
day thereafter (or such earlier date on which the Event of Default relating to such failure shall
have been cured or waived prior to such 365th day) and will be payable in the same manner as
regular interest on the Securities. On such 365th day (or earlier, if the Event of Default
relating to such failure is cured or waived prior to such 365th day) such Default Additional
Interest will cease to accrue and the Securities will be subject to acceleration as provided above
if the Event of Default is continuing. In no event will Default Additional Interest accrue at a
rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or
circumstances giving rise to the requirement to pay the Default Additional Interest. This provision
will not affect the rights of holders of Securities in the event of the occurrence of any other
Event of Default.

ARTICLE 7

Trustee

     Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same
degree of care and skill in its exercise as a prudent Person would exercise or use under the
circumstances in the conduct of such Person’s own affairs.

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

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

48

 

     (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as
to the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture. However, the Trustee shall examine the certificates and opinions to
determine whether or not they conform to the requirements of this Indenture.

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

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

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

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

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

     (e) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company.

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

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

     (h) Every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section and to the
provisions of the TIA.

     Section 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to
be genuine and to have been signed or presented by the proper person. The Trustee need not
investigate any fact or matter stated in the document.

49

 

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

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

     (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers.

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

     (f) The Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond, note, debenture, other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see
fit.

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

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

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

50

 

     Section 7.05. Notice of Defaults. (a) The Trustee shall not be deemed to have notice of any
Default, other than a payment default, unless a Trust Officer shall have been advised in writing
that a Default has occurred. No duty imposed upon the Trustee in this Indenture shall be
applicable with respect to any Default of which the Trustee is not deemed to have such notice.

     (b) If a default occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Securityholder notice of the default within the earlier of 90 days after it occurs or
30 days after it is known to a Trust Officer or written notice of it is received by the Trustee.
Except in the case of a default in payment of principal or interest on any Security (including
payments pursuant to the redemption or repurchase provisions of such Security), the Trustee may
withhold notice if and so long as a committee of its Trust Officers in good faith determines that
withholding notice is in the interests of the Securityholders.

     Section 7.06. Reports by Trustee to Securityholders. As promptly as practicable, beginning
with the May 15 following the first anniversary of the date of this Indenture, and in any event
prior to May 15 in each subsequent year, the Trustee shall, to the extent that any of the events
described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, mail to
each Securityholder a brief report dated as of May 15 that complies with Section 313(a) of the TIA.
The Trustee shall also comply with Section 313(b) of the TIA.

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

     Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to
time such compensation as the Company and the Trustee shall from time to time agree in writing.
The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the
compensation for its services. Such expenses shall include the reasonable compensation and
expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.
The Company shall indemnify the Trustee, and hold it harmless, against any and all loss, liability
or expense (including reasonable attorneys’ fees) incurred by or in connection with the offer and
sale of the Securities or the administration of this trust and the performance of its duties
hereunder. The Trustee shall notify the Company of any claim for which it may seek indemnity
promptly upon obtaining actual knowledge thereof; provided that any failure so to notify the
Company shall not relieve the Company of its indemnity obligations hereunder. The Company shall
defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s
expense in the defense. Such indemnified parties may have separate counsel and the

51

 

Company shall
pay the fees and expenses of such counsel; provided that the Company shall not be required to pay
such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified
parties’ reasonable judgment, there is no conflict of interest between the Company and such parties
in connection with such defense. The Company need not reimburse any expense or indemnify against
any loss, liability or expense incurred by an indemnified party through such party’s own willful
misconduct and negligence.

     To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Securities on all money or property held or collected by the Trustee other than money
or property held in trust to pay principal of and interest and any liquidated damages on particular
Securities.

     The Company’s payment obligations pursuant to this Section shall survive the satisfaction or
discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy
law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the
occurrence of an Event of Default specified in Section 6.01(h) or 6.01(i) with respect to the
Company, the expenses are intended to constitute expenses of administration under the Bankruptcy
Law.

     Section 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the
Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by
so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee
if:

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

     (b) the Trustee is adjudged bankrupt or insolvent;

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

     (d) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Securities and such Securityholders do not reasonably promptly appoint a successor
Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event
being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Securityholders. The

52

 

retiring Trustee shall promptly transfer all property held by it as Trustee
to the successor Trustee, subject to the lien provided for in Section 7.07.

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

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

     Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

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

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

     Section 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the
requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least
$100,000,000 as set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA § 310(b); provided that there shall be excluded from the operation of TIA §
310(b)(1) any indenture or indentures under which other securities or certificates of interest or
participation in other securities of the Company are outstanding if the requirements for such
exclusion set forth in TIA § 310(b)(1) are met.

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

53

 

ARTICLE 8

Discharge of Indenture

     Section 8.01. Discharge of Liability on Securities. (a) At any time after all outstanding
Securities have become due and payable, whether at Maturity Date or as a result of the mailing of a
notice of redemption or upon a repurchase pursuant to Article 3 hereof, and any pending conversions
have been completed (including delivery of all cash and shares of Common Stock, if any, deliverable
pursuant to such conversions in accordance with Section 10.13) then this Indenture shall, subject
to Section 8.01(b), cease to be of further effect when (i) the Company delivers to the Trustee all
outstanding Securities (other than
Securities replaced pursuant to Section 2.12) for cancellation or (ii) the Company irrevocably
deposits with the Trustee money sufficient to pay at maturity or upon redemption or repurchase all
outstanding Securities, including interest thereon to but excluding, maturity or such redemption or
repurchase date (other than Securities replaced pursuant to Section 2.12), and if in each such case
the Company pays all other sums payable hereunder by the Company. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’
Certificate and an Opinion of Counsel and at the cost and expense of the Company.

     (b) Notwithstanding clause (a) above, the Company’s obligations in Sections 2.05, 2.06, 2.07,
2.08, 2.09, 2.10, 2.12, 2.13, 7.07, 7.08 and in this Article 8 shall survive until the Securities
have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.03 and 8.04
shall survive.

     Section 8.02. Application of Trust Money. The Trustee shall hold in trust money deposited
with it pursuant to this Article 8. It shall apply the deposited money through the Paying Agent
and in accordance with this Indenture to the payment of principal of and interest on the Securities
in accordance with this Indenture in relation to the conversion of Securities pursuant to the terms
hereof.

     Section 8.03. Repayment to Company. The Trustee and the Paying Agent shall promptly turn
over to the Company upon request any excess money or securities held by them at any time.

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

     Section 8.04. Reinstatement. If the Trustee or Paying Agent is unable to apply any money in
accordance with this Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the

54

 

Company’s obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time
as the Trustee or Paying Agent is permitted to apply all such money in accordance with this Article
8; provided that, if the Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Securityholders of such Securities to receive such payment from the money held by the Trustee
or Paying Agent.

ARTICLE 9

Amendments

     Section 9.01. Without Consent of Securityholders. The Company and the Trustee may amend this
Indenture or the Securities without notice to or consent of any Securityholder:

     (a) to provide for conversion rights of Holders of the Securities and the Company’s repurchase
obligations in connection with a Fundamental Change in the event of any reclassification of Common
Stock, merger or consolidation, or sale, conveyance, transfer or lease of the Company’s property
and assets substantially as an entirety;

     (b) to secure the Securities including provisions regarding the circumstances under which
collateral may be released or substituted;

     (c) evidence the succession of another Person to the Company under the terms of this Indenture
or successive successions, and provide for the assumption of the Company’s obligations to the

Company’s property and assets substantially as an entirety;

     (d) to surrender any right or power conferred upon the Company;

     (e) to add to the covenants of the Company for the benefit of the Securityholders;

     (f) to cure any ambiguity or correct or supplement any inconsistency or defective provision

amendment made solely to conform the provisions of this Indenture to the description of the
Securities contained in the Offering Memorandum prepared by the Company dated as of October 18,
2011 will not be deemed to adversely affect the interests of the Holders of the Securities;

55

 

     (g) to make any provision with respect to matters or questions arising under this Indenture
that the Company may deem necessary or desirable and that shall not be inconsistent with provisions
of this Indenture; provided that such change or modification does not, in the good faith opinion of
the Board of Directors, adversely affect the interests of the Holders of the Securities in any
material respect;

     (h) to increase the Conversion Rate in accordance with this Indenture;

     (i) to comply with any requirements of the SEC in connection with qualifying, or maintaining
the qualification of, this Indenture under the TIA;

     (j) to add or provide for the guarantee of obligations under the Securities or additional
obligors on the Securities; or

     (k) to provide for a successor Trustee.

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

     Section 9.02. With Consent of Securityholders. The Company and the Trustee may amend this
Indenture or the Securities with the written consent or affirmative vote of the Holders of at least
a majority in principal amount of the Securities then outstanding (including consents obtained in
connection with a tender offer or exchange offer for the Securities), without notice to any other
Securityholder. However, without the consent of each Holder of an outstanding Security affected,
an amendment may not:

     (a) extend the Maturity Date;

     (b) reduce the rate of or extend the time for payment of interest on any Security;

     (c) reduce the principal amount of any Security;

     (d) reduce any amount payable upon redemption or repurchase of any Security;

     (e) impair the right of a Holder to institute suit for payment of any Securities;

     (f) make any Security payable in a currency other than that stated in the Security;

56

 

     (g) change the obligation of the Company to redeem any Security called for redemption in a
manner adverse to the Holders;

     (h) change the obligation of the Company to repurchase any Security at the option of the
Holder or upon a Fundamental Change in a manner adverse to the Holders;

     (i) except as required by this Indenture, adversely affect the right of a Holder to convert
any Securities into cash and, if applicable, shares of Common Stock (or to the extent otherwise
applicable, other property, including cash, receivable upon conversion pursuant to the terms of
this Indenture) or reduce the Conversion Rate, except as otherwise permitted pursuant to this
Indenture; or

     (j) make any changes in Section 6.04 or 6.07, the first sentence of this Section 9.02
regarding the percentage of the Securities required for consent or any modification of this
Indenture that does not require the consent of each affected Holder or the second sentence of this
Section 9.02.

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

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

     Section 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or the
Securities shall comply with the TIA as then in effect if required to so comply.

     Section 9.04. Revocation and Effect of Consents and Waivers. A consent to an amendment or a
waiver by a Securityholder of a Security shall bind the Securityholder and every subsequent
Securityholder of that Security or portion of the Security that evidences the same debt as the
consenting Securityholder’s Security, even if notation of the consent or waiver is not made on the
Security. However, any such Securityholder or subsequent Securityholder may revoke the consent or
waiver as to such Securityholder’s Security or portion of the Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective. After an amendment
or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes
effective once (i) the requisite number of consents have been received by the Company or the
Trustee and (ii) in the case of an amendment, such amendment has been executed by the Company and
the Trustee.

57

 

     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Securityholders entitled to give their consent or take any other action described
above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at
such record date (or their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such action, whether or
not such Persons continue to be Securityholders after such record date. No consent shall be valid
or effective for more than 120 days after such record date unless consents from holders of the
principal amount of Securities required hereunder to give such consent or take such action shall
have also been given and not revoked within such 120-day period.

     Section 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a
Security, the Trustee may require the Securityholder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the
Security regarding the changed terms and return it to the Securityholder. Alternatively, if the
Company or the Trustee so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the
appropriate notation or to issue a new Security shall not affect the validity of such amendment.

     Section 9.06. Trustee to Sign Amendments. The Trustee shall sign any amendment authorized
pursuant to this Article 9 if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In
signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory
to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an
Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or
permitted by this Indenture and that such amendment is the legal, valid and binding obligation of
the Company enforceable against them in accordance with its terms, subject to customary exceptions,
and complies with the provisions hereof (including Section 9.03).

ARTICLE 10

Conversion of Securities

     Section 10.01. Right to Convert. (a) Subject to and upon compliance with the provisions of
this Indenture, on or prior to the close of business on the Business Day immediately preceding
Maturity Date, the Holder of any Securities not previously redeemed or repurchased shall have the
right, at such Holder’s option, to convert the principal amount of the Securities held by such
Holder, or any portion of such principal amount which is an integral multiple of $1,000, into

58

 

cash
and, if applicable, fully paid and non-assessable shares of Common Stock (as such shares shall then
be constituted) as described in Section 10.13, at the Conversion Rate in effect at such time, by
surrender of the Securities so to be converted in whole or in part, together with any required
funds, under the circumstances described in this Section 10.01 and in the manner provided in
Section 10.02. The Securities shall be convertible only upon the occurrence of one of the
following events:

     (i) prior to May 1, 2031, on any date during any Fiscal Quarter beginning after
December 31, 2011 (and only during such Fiscal Quarter), if the Closing Sale Price of a
share of Common Stock was more than 130% of the then current Conversion Price for at least
20 Trading Days in the period of 30 consecutive Trading Days ending on the last Trading
Day of the previous Fiscal Quarter;

     (ii) at any time on or after May 1, 2031;

     (iii) with respect to any Securities called for redemption pursuant to Section 3.01,
until the close of business on the Business Day immediately prior to the relevant
Redemption Date;

     (iv) if the Company distributes to all or substantially all holders of Common Stock,
rights or warrants entitling them to purchase, for a period of 45 calendar days or less,
Common Stock at a price less than the average Closing Sale Price per share of the Common
Stock for the ten Trading Days preceding the declaration date for such distribution;

     (v) if the Company distributes to all or substantially all holders of Common Stock,
cash or other assets, debt securities or rights to purchase the Company’s securities,
which distribution has a per share value exceeding 10% of the Closing Sale Price per share
of the Common Stock on the Trading Day preceding the declaration date for such
distribution;

     (vi) if the Company consolidates with or merges with or into another Person or is a
party to a binding share exchange or conveys, transfers, sells, leases or otherwise
disposes of all or substantially all of its properties and assets in each case in a
transaction not constituting a Fundamental Change, pursuant to which the Common Stock
would be converted into cash, securities and/or other property, at any time beginning 15
calendar days prior to the date announced by the Company as the anticipated effective date
of the transaction and until and including the date which is 15 calendar days after the
date that is the actual effective date of such transaction;

59

 

     (vii) if a Fundamental Change occurs, at any time beginning on the 25th Scheduled
Trading Day prior to the anticipated effective date of the Fundamental Change until 5:00
p.m., New York City time, on the Business Day preceding the Fundamental Change Repurchase
Date relating to such Fundamental Change; or

     (viii) during the five consecutive Business Day period immediately following any five
consecutive Trading Day period in which the Trading Price for $1,000 principal amount of
the Securities for each day during such five Trading Day period was less than 98% of the
Closing Sale Price of a share of Common Stock and multiplied by the then applicable
Conversion Rate on each such day.

     (b) (i) The Company shall notify the Trustee in writing on or prior to the fifth Business Day
following the first day of each Fiscal Quarter (commencing prior to May 1, 2031, beginning with the
Fiscal Quarter ending December 31, 2011) if the condition to conversion set forth in Section
10.01(a) above shall have been satisfied with respect to such Fiscal Quarter.

     (ii) The Trustee shall have no obligation to determine the Trading Price of the Securities and
whether the Securities are convertible pursuant to clause (viii) of Section 10.01(a) unless the
Company has requested in writing such determination; and the Company shall have no obligation to
make such request unless a Holder of the Securities provides the Company with reasonable written
evidence that the Trading Price of $1,000 principal amount of the Securities would be less than 98%
of the product of the Closing Sale Price of the Common Stock and the then current Conversion Rate
and requests that the Company requests such determination from the Trustee. At such time, the
Company shall instruct the Trustee to, and the Trustee shall, determine the Trading Price of the
Securities beginning on the next Trading Day and for each following Trading Day until the minimum
Trading Price threshold is exceeded. If the Company does not instruct the Trustee to determine the
Trading Price of the Securities when required, the Trading Price for each day the Company fails to
do so will be deemed to be less than 98% of the product of the Closing Sale Price of the Company’s
Common Stock and the then current Conversion Rate.

     The Trustee shall be entitled at its sole discretion to consult with the Company and to
request the assistance of the Company in connection with the Trustee’s duties and obligations
pursuant to this Section 10.01(b)(ii) (including without limitation the calculation or
determination of the Closing Sale Price and the Trading Price), and the Company shall, if requested
by the Trustee, cooperate with, and provide assistance to, the Trustee in carrying out its duties
under this Section 10.01(b)(ii). Upon determination of the Closing Sale Price and the Trading
Price, the Trustee shall notify the Company in writing of such determination.

60

 

     (c) In the case of a distribution contemplated by clauses (iv) or (v) of Section 10.01(a), the
Company shall notify Holders of Securities at least 25 Scheduled Trading Days prior to the Ex-Date
for such distribution (the “Distribution Notice”). Once the Company has given the Distribution
Notice, Holders may surrender their Securities for conversion at any time until the earlier of (i)
5:00 p.m., New York City time, on the Business Day immediately preceding the Ex-Date or (ii) the
Company’s announcement that such distribution will not take place. In the event of a distribution
contemplated by clauses (iv) or (v) of Section 10.01(a), Holders may not convert the Securities if
the Holders may otherwise participate in such distribution without converting their Securities at
the same time that holders of Common Stock participate as if the Holder had held a number of shares
of Common Stock equal to the Conversion Rate multiplied by the principal amount (expressed in
thousands) of the Securities held by the Holder.

     (d) Whenever the Securities shall become convertible pursuant to this Section 10.01, the
Company or, at the Company’s request, the Trustee in the name and at the expense of the Company,
shall notify the Holders of the event triggering such convertibility in the manner provided in
Section 11.02, and the Company shall also publicly announce such information and publish it on the
Company’s website or through another public medium that the Company may use.
Any notice so given shall be conclusively presumed to have been duly given, whether or not the
Holder receives such notice. The Company shall notify Holders as promptly as practicable after the
Company publicly announces such transaction, which shall be at least 25 Scheduled Trading Days
prior to the anticipated effective date of any Fundamental Change in the case of a transaction to
which the Company is a party.

     (e) Securities in respect of which a Holder has delivered a Fundamental Change Repurchase
Notice or a Repurchase Notice exercising such Holder’s right to require the Company to repurchase
such Securities pursuant to Section 3.04 or 3.05, as the case may be, may be converted only if such
Fundamental Change Repurchase Notice or a Repurchase Notice, as applicable, is withdrawn in
accordance with Section 3.07 prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Fundamental Change Repurchase Date or the Repurchase Date, as applicable.

     (f) A Holder of Securities is not entitled to any rights of a Holder of Common Stock until
such holder has converted his Securities to Common Stock, and only to the extent such Securities
are deemed to have been converted to Common Stock under this Article 10.

     Section 10.02. Exercise of Conversion Right; Issuance of Common Stock on Conversion; No
Adjustment for Interest or Dividends. In order to exercise the conversion right with respect to
any Securities in certificated form, the Company must receive at the office or agency of the
Company, which will initially be the office or agency of the Trustee maintained for that purpose in
The City of New

61

 

York, such Securities with the original or facsimile of the form entitled
“Conversion Notice” on the reverse thereof, duly completed and manually signed, together with such
Securities duly endorsed for transfer, together with any other required transfer documents,
accompanied by the funds, if any, required by this Section 10.02. Such notice shall also state the
name or names (with address or addresses) in which the certificate or certificates for shares of
Common Stock which shall be issuable on such conversion shall be issued, and shall be accompanied
by transfer or similar taxes, if required pursuant to Section 10.08.

     In order to exercise the conversion right with respect to any interest in a Global Security,
the Holder must complete, or cause to be completed, the appropriate instruction form for conversion
pursuant to the Depositary’s book-entry conversion program; deliver, or cause to be delivered, by
book-entry delivery an interest in such Global Security; furnish appropriate endorsements and
transfer documents if required by the Company or the Trustee or Conversion Agent; and pay the
funds, if any, required by this Section 10.02 and any transfer or similar taxes if required
pursuant to Section 10.08.

     After satisfaction of the requirements for conversion set forth above, the Company will
deliver cash and Common Stock, if any, in accordance with Section 10.13. In case any Securities of
a denomination greater than $1,000 shall
be surrendered for partial conversion, and subject to Section 2.03, the Company shall execute
and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered,
without charge to the Holder, a new Security or Securities in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered Securities.

     Each conversion shall be deemed to have been effected as to any such Securities (or portion
thereof) on the date on which the requirements set forth above in this Section 10.02 have been
satisfied as to such Securities (or portion thereof) (the “Conversion Date”) and such Securities
will be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the
Conversion Date. The Person in whose name the certificate or certificates for any shares of Common
Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the
close of business on the last Trading Day of the related Conversion Observation Period.

     Upon the conversion of an interest in a Global Security, the Trustee (or other Conversion
Agent appointed by the Company), or the custodian for the Global Security at the direction of the
Trustee (or other Conversion Agent appointed by the Company), shall make a notation on such Global
Security as to the reduction in the principal amount represented thereby. The Company shall notify
the Trustee in writing of any conversions of Securities effected through any Conversion Agent other
than the Trustee.

62

 

     Section 10.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common
Stock or scrip certificates representing fractional shares shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one time by the same
Holder, the number of full shares that shall be issuable upon conversion shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions thereof to the
extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon
the conversion of any Security or Securities, the Company shall make an adjustment and payment
therefor in cash to the Holder of Securities at a price equal to the Closing Sale Price on the last
Trading Day of the Conversion Observation Period.

     Section 10.04. Conversion Rate. Each $1,000 principal amount of the Securities shall be
convertible into cash and/or the number of shares of Common Stock, if any, based upon the
Conversion Rate, subject to adjustment as provided in Section 10.05 and Section 10.06. The Company
shall settle its obligation to convert the Securities as provided in Section 10.13.

     Section 10.05. Adjustment to Conversion Rate upon a Non-Stock Change of Control. (a) If and
only to the extent a Holder elects to convert Securities at any time following the date on which a
Non-Stock Change of Control becomes effective (the “Effective Date”) but before 5:00 p.m., New York
City time, on the Business Day immediately preceding the related Fundamental Change
Repurchase Date, the Company shall increase the Conversion Rate applicable to such converted
Securities by a number of additional shares of Common Stock (the “Additional Shares”) as set forth
below. The number of Additional Shares of Common Stock shall be determined by reference to the
table below, based on the Effective Date and the price (the “Stock Price”) paid per share for the
Common Stock in the Non-Stock Change of Control. If holders of Common Stock receive only cash in
the Non-Stock Change of Control, the Stock Price shall be the cash amount paid per share.
Otherwise, the Stock Price shall be the average of the Closing Sale Prices of the Common Stock on
the five Trading Days prior to but not including the Effective Date of such Non-Stock Change of
Control.

     The following table sets forth the number of Additional Shares per $1,000 principal amount of
Securities by which the Conversion Rate shall be increased for conversions of Securities in
connection with a Non-Stock Change of Control pursuant to Section 10.01(a)(vii) based on the
Effective Date and Stock Price for the Non-Stock Change of Control:

     (b) If the Stock Price or Effective Date for a Non-Stock Change of Control
are not set forth in the table above, then:

     (1) if the Stock Price is between two Stock Price amounts on the table or the
Effective Date is between two Effective Dates on the table, the number of Additional
Shares of Common Stock will be determined by straight-line interpolation between the
number of Additional Shares of Common Stock set forth for the higher and lower Stock Price
amounts and the two dates, as applicable, based on a 365-day year;

     (2) if the Stock Price in excess of $100.00 per share (subject to adjustment), no
Additional Shares of Common Stock shall be issued upon conversion as set forth in Section
10.05(c); or

     (3) if the Stock Price less than $23.49 per share (subject to adjustment), no
Additional Shares of Common Stock shall be issued upon conversion as set forth in Section
10.05(c).

     Notwithstanding the foregoing, in no event will the Conversion Rate as adjusted pursuant to
this Section 10.05 exceed 42.5713 per $1,000 principal amount of the Securities.

     (c) The numbers of Additional Shares of Common Stock set forth in the table in Section
10.05(a) shall be adjusted as of any date on which the Conversion Rate is adjusted in the same
manner in which the Conversion Rate is adjusted. The Stock Prices set forth in the table in
Section 10.05(a) shall be adjusted, as of any date on which the Conversion Rate is adjusted, to
equal the Stock Price applicable immediately prior to such adjustment multiplied by a fraction, of
which:

     (1) the numerator shall be the Conversion Rate immediately prior to the adjustment;
and

64

 

     (2) the denominator shall be the Conversion Rate as so adjusted.

     (d) The Company shall provide written notice to all Holders and to the Trustee as promptly as
practicable after the Company publicly announces such Non-Stock Change of Control, which shall be
at least 20 calendar days prior to the anticipated Effective Date of a Non-Stock Change of Control
to which the Company is a party.

     Section 10.06. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company, without duplication, as follows:

     (a) In case the Company shall, at any time or from time to time while any of the Securities
are outstanding, pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock to all or substantially all holders of its outstanding shares of Common Stock, then
the Conversion Rate in effect immediately prior to the opening of business on the Ex-Date for such
dividend or other distribution shall be increased by multiplying such Conversion Rate by a
fraction,

     (1) the numerator of which shall be the sum of (A) the number of shares of Common
Stock outstanding immediately prior to the opening of business on the Ex-Date for such
dividend or other distribution plus (B) the total number of shares of Common Stock
constituting such dividend or other distribution; and

     (2) the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to the opening of business on the Ex-Date for such dividend
or other distribution,

such increase to become effective immediately after the opening of business on the Ex-Date for such
dividend or other distribution. If any dividend or distribution of the type described in this
Section 10.06(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted
to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared.

     (b) In case outstanding shares of Common Stock shall be subdivided or split into a greater
number of shares of Common Stock, the Conversion Rate in effect immediately prior to the opening of
business on the effective date for such subdivision shall be proportionately increased, and
conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Rate in effect immediately prior to the opening of business
on the effective date for such combination shall be proportionately reduced, such increase or
reduction, as the case may be, to

65

 

become effective immediately after the opening of business on the
effective date for such subdivision or combination.

     (c) In case the Company shall issue rights or warrants (other than any rights or warrants as
to which an adjustment was effected pursuant to Section 10.06(d)) to all or substantially all
holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase, for
a period of up to 45 calendar days, shares of Common Stock at a price per share less than the
Current Market Price on the declaration date for such issuance, the Conversion Rate shall be
adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the opening of business on the Ex-Date for such issuance by a fraction,

     (1) the numerator of which shall be the sum of (A) the number of shares of Common
Stock outstanding immediately prior to the opening of business on the Ex-Date for such
issuance plus (B) the total number of additional shares of Common Stock offered for
subscription or purchase, and

     (2) the denominator of which is the sum of (A) the number of shares of Common Stock
outstanding immediately prior to the opening of business on the Ex-Date for such issuance
plus (B) the total number of shares that the aggregate offering price of the shares so
offered would purchase at such Current Market Price.

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

     (d) Except as set forth in Section 10.06(b), in case the Company shall, by dividend or
otherwise, distribute to all or substantially all holders of its

66

 

outstanding shares of Common Stock
shares of any class of Capital Stock of the Company (other than the Common Stock) or evidences of
its indebtedness or assets, including securities, but excluding (i) any rights or warrants as to
which an
adjustment was effected pursuant to Section 10.06(c), (ii) any dividends or distributions in
connection with a reclassification, changes, consolidation, merger, combination or sale or
conveyance to which Section 10.07 applies, (iii) any dividends or distributions paid exclusively in
cash or (iv) any dividends or distributions as to which an adjustment was effected pursuant to
Section 10.06(a) (any of the foregoing hereinafter in this Section 10.06(d)) called the
“Distributed Assets”), then, in each such case, the Conversion Rate shall be increased so that the
same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately
prior to the opening of business on the Ex-Date for such distribution by a fraction,

     (1) the numerator of which shall be the Current Market Price on the Ex-Date for such
distribution; and

     (2) the denominator of which shall be the Current Market Price on the Ex-Date for
such distribution minus the Fair Market Value (as determined by the Board of Directors,
whose determination shall be conclusive, and described in a resolution of the Board of
Directors) of the portion of the Distributed Assets so distributed applicable to one share
of Common Stock,

such adjustment to become effective immediately after the opening of business on the Ex-Date for
such distribution; provided that if the then Fair Market Value (as so determined) of the portion of
the Distributed Assets so distributed applicable to one share of Common Stock is equal to or
greater than the Current Market Price on such Ex-Date in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder of Securities shall have the right to receive, at the
same time and upon the same terms as holders of Common Stock, in addition to the cash and the
shares of Common Stock, if any, issuable upon conversion of Securities, for each $1,000 principal
amount of Securities the amount of Distributed Assets such Holder would have received had such
Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately
prior to the record date for the dividend or distribution. If such dividend or distribution is not
so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared.

     If the Board of Directors determines the Fair Market Value of any distribution for purposes of
this Section 10.06(d) by reference to the actual or when issued trading market for any Distributed
Assets comprising all or part of such distribution, it must in doing so consider the prices in such
market over the same period (the “Reference Period”) used in computing the Current Market Price of
the Common Stock to the extent possible, unless the Board of Directors

67

 

determines in good faith
that determining the Fair Market Value during the Reference Period would not be in the best
interest of the Holders.

     Notwithstanding the foregoing, in the event any such distribution consists of shares of
Capital Stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a
“Spin-Off”), the Conversion Rate in effect immediately before the Ex-Date for the distribution will
be increased by multiplying the Conversion Rate by an adjustment factor equal to the sum of the
Daily Adjustments (as defined below) for each of the 10 consecutive Trading Days beginning on the
Ex-Date for the distribution. The “Daily Adjustment” for any given Trading Day is equal to the
fraction:

     (1) the numerator of which is the Closing Sale Price of the Common Stock on that
Trading Day plus the Closing Sale Price of the portion of those shares of Capital Stock or
similar equity interests so distributed applicable to one share of the Common Stock on
that Trading Day, and

     (2) the denominator of which is the product of 10 and the Closing Sale Price of the
Common Stock on that Trading Day.

     The adjustment to the Conversion Rate in the event of a Spin-Off will occur retroactively on
the Ex-Date for the distribution. In the event that such dividend or distribution is not so paid
or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be
in effect if such dividend or distribution had not been declared.

     For purposes of this Section 10.06(d) and Sections 10.06(a) and 10.06(c), any dividend or
distribution to which this Section 10.06(d) is applicable that also includes shares of Common
Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall
be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or
shares of Capital Stock other than such shares of Common Stock or rights or warrants (and any
Conversion Rate adjustment required by this Section 10.06(d) with respect to such dividend or
distribution shall then be made) immediately followed by (2) a dividend or distribution of such
shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment
required by Section 10.06(a) or 10.06(c) with respect to such dividend or distribution shall then
be made), except the “Ex-Date for such dividend or distribution” shall be substituted for the
“Ex-Date for such dividend or other distribution” within the meaning of Section 10.06(a) and the
“Ex-Date for such issuance” within the meaning of Section 10.06(c) and any shares of Common Stock
included in such dividend or distribution shall not be deemed “outstanding immediately prior to the
opening of business on the Ex-Date for such dividend or distribution” within the meaning of Section
10.06(a).

68

 

     (e) In case the Company shall, by dividend or otherwise, distribute to all or substantially
all holders of its Common Stock cash (including any quarterly cash dividend, but excluding (x) any
dividend or distribution in connection with
the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary
and (y) any dividend or distribution in connection with a merger, consolidation or sale to which
Section 10.07 applies), then the Conversion Rate shall be increased so that the same shall equal
the rate determined by multiplying the Conversion Rate in effect immediately prior to the opening
of business on the Ex-Date for such distribution by a fraction,

     (1) the numerator of which shall be the Current Market Price on the Ex-Date for such
distribution; and

     (2) the denominator of which shall be the Current Market Price of the Common Stock on
the Ex-Date for such distribution minus the amount of the cash dividend or distribution
applicable to one share of Common Stock,

such adjustment to be effective immediately after the opening of business on the Ex-Date for such
distribution; provided that in the event the portion of the cash so distributed applicable to one
share of Common Stock is equal to or greater than the Current Market Price, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Holder of Securities shall have
the right to receive at the same time as holders of the Common Stock for each $1,000 principal
amount of Securities the amount of cash such Holder would have received had such Holder owned a
number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the
record date for the dividend or distribution. If such dividend or distribution is not so paid or
made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared.

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

69

 

     (1) the numerator of which shall be the sum of (x) the Fair Market Value (determined
as aforesaid) of the aggregate consideration paid to stockholders for all shares accepted
for purchase the tender or exchange offer (the “Purchased Shares”) and (y) the product of
the number of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Closing Sale Price of a share of Common Stock on the Trading Day
next succeeding the Expiration Time, and

     (2) the denominator of which shall be the product of the number of shares of Common
Stock outstanding (including any Purchased Shares) at the Expiration Time multiplied by
the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the
Expiration Time,

such adjustment to become effective immediately after the close of business on the Trading Day next
succeeding the Expiration Time. 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 any such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer
had not been made for the shares not purchased. In no event shall the Conversion Rate be reduced
pursuant to this Section 10.06(f).

     (g) Subject to Section 6.09, the Company may in its sole discretion make such increases in the
Conversion Rate, in addition to those required by Sections 10.06(a)-(f), as the Board of Directors
considers to be advisable to avoid or diminish any U.S. federal income tax to holders of Common
Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes; provided that such increase in the Conversion Rate
shall not adversely affect the interests of the Holders of Securities (after taking into account
U.S. federal income tax and other consequences of such increase).

     (h) Subject to Section 6.09, to the extent permitted by applicable law, the Company from time
to time may increase the Conversion Rate by any amount for any period of time if the period is at
least 20 Business Days, the increase is irrevocable during the period and the Board of Directors
shall have made a determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to Holders of record of the Securities a notice of the
increase, which notice will be given at least 15 days prior to the effectiveness of any such
increase, and such notice shall state the increased Conversion Rate and the period during which it
will be in effect.

70

 

     (i) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that any
adjustments that by reason of this Section 10.06(i) are not required to be made shall be carried
forward and the Company shall make
such carry forward adjustments, regardless of whether the aggregate adjustment is less than
1%, (x) annually on the anniversary of the first date of the issue of the Securities and otherwise
(y)(1) on each day from and after the 25th Scheduled Trading Day prior to the maturity of the
Securities (whether its Maturity Date or otherwise), (2) if the Securities are called for
redemption, on each day from and including the 30th calendar day before the Redemption Date and (3)
in connection with a Fundamental Change or Non-Stock Change of Control on each day from and
including the 10th calendar day prior to the anticipated Effective Date of the Fundamental Change
or Non-Stock Change of Control to the Effective Date of the Fundamental Change or Non-Stock Change
of Control. All calculations under this Article 10 shall be made by the Company and shall be made
to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.
No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for
reinvestment of dividends or interest or for any issuance of Common Stock or convertible or
exchangeable securities or rights to purchase Common Stock or convertible or exchangeable
securities. Interest will not accrue on any cash into which the Securities are convertible.

     (j) Whenever the Conversion Rate is adjusted as herein provided, the Company will issue a
press release through Business Wire containing the relevant information and make this information
available on the Company’s website or through another public medium as the Company may use at that
time. In addition, the Company shall promptly file with the Trustee and any Conversion Agent other
than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment
and setting forth a brief statement of the facts requiring such adjustment. Unless and until a
Trust Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not
be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last
Conversion Rate of which it has actual knowledge is still in effect. Promptly after delivery of
such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate
setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective
and shall mail such notice of such adjustment of the Conversion Rate to the Holder of each
Securities at his last address appearing on the Register, within 20 calendar days after execution
thereof. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment.

     (k) In any case in which this Section 10.06 provides that an adjustment shall become
effective (1) upon the opening of business on an Ex-Date, (2) immediately after the record date for
an event, or (3) after the Expiration Time for any tender or exchange offer pursuant to Section
10.06(f), (each a

71

 

“Determination Date”), the Company may elect to defer until the occurrence of the
applicable distribution, issuance of Common Stock or payment (an “Adjustment Event”) triggering a
Conversion Rate adjustment (x) issuing to the Holder of any Securities converted after such
Determination Date and before the
occurrence of such Adjustment Event, the additional cash, shares of Common Stock, if any, or
other securities or property issuable upon such conversion by reason of the adjustment required by
such Adjustment Event over and above the cash, the Common Stock, or combination of cash and Common
Stock, issuable upon such conversion before giving effect to such adjustment and (y) paying to such
Holder any amount in cash in lieu of any fractional share.

     (l) For purposes of this Section 10.06, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

     (m) No adjustment to the Conversion Rate shall be made pursuant to Section 10.06 on account of
a distribution on Common Stock, if the Holders of the Securities will otherwise participate for
each $1,000 principal amount of Securities in such distribution without conversion as a result of
holding the Securities at the same time and on the same terms as a holder of a number of shares of
Common Stock equal to the Conversion Rate.

     (n) Notwithstanding the foregoing, no adjustment to the Conversion Rate need be made for:

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

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

     (o) Notwithstanding anything to the contrary in this Indenture, if an event occurs that would
result in an increase in the Conversion Rate by an amount in excess of limitations imposed by any
shareholder approval rules or listing standards of any national securities exchange that are
applicable to the Company, the Company will, at its option, either obtain stockholder approval of
any issuance of Common Stock upon conversion of the Securities in excess of such limitations or
deliver cash in lieu of any shares of Common Stock otherwise deliverable upon conversions in excess
of such limitations based on the VWAP Price on each Trading Day of the relevant Observation Period
in respect of which, in lieu of

72

 

delivering shares of Common Stock, the Company delivers cash
pursuant to this Section 10.06(o).

     (p) Notwithstanding this Section 10.06 and the other provisions of Article 10, if any
Conversion Rate adjustment becomes effective, or any Ex-Date (relating to a required Conversion
Rate adjustment) occurs, during the period beginning on a Conversion Date and ending on close of
business on the last Trading Day of the corresponding Conversion Observation Period, the Board of
Directors may make adjustments to the Conversion Rate or the amount of cash or number of shares of
Common Stock issuable upon conversion of the Securities, as may be necessary or appropriate to
effect the intent of this Section 10.06 and the other provisions of Article 10 and to avoid unjust
or inequitable results, as determined in good faith by the Board of Directors. Any adjustment made
pursuant to this Section 10.06(p) shall apply in lieu of the adjustment or other term that would
otherwise be applicable.

     Section 10.07. Effect of Reclassification, Consolidation, Merger or Sale. If any of the
following events occur, namely:

     (a) any reclassification or change of the outstanding Common Stock (other than as a result of
a subdivision or combination),

     (b) any consolidation or merger of the Company with or into another Person or

     (c) any sale, lease, transfer, conveyance or other disposition of all or substantially all of
the Company’s assets and those of its Subsidiaries taken as a whole to any other Person or Persons,

as a result of which holders of Common Stock shall be entitled to receive stock, other securities
or other property or assets (including cash or any combination thereof) with respect to or in
exchange for such Common Stock, in each case, at the effective time of such transaction, the
Company or the successor, purchasing corporation or transferee, as the case may be, shall execute
with, and deliver to, the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental indenture, if such
supplemental indenture is then required to so comply) providing that such Securities shall, without
the consent of any Holders of Securities, become convertible into the kind and amount of shares of
stock, other securities or other property or assets (including cash or any combination thereof)
(the “Applicable Consideration”) that such Holder would have been entitled to receive upon such
reclassification, change, consolidation, merger, sale, lease, transfer, conveyance or other
disposition, had each $1,000 principal amount of Securities held by such Holder been converted into
a number of shares of Common Stock equal to the Conversion Rate immediately prior to such
reclassification, change, consolidation, merger, sale, lease, transfer, conveyance or other
disposition, except that at and

73

 

after the effective time of the transaction (w) the amount
otherwise payable in cash upon conversion of the Securities will continue to be payable in cash,
(x) the Company will continue to have the right to determine the form of consideration to

be paid or delivered, as the case may be, in respect of the remainder, if any, of the Company’s
conversion obligation in excess of the aggregate principal amount of the Securities being
converted, (y) the number of shares of the Company’s Common Stock otherwise deliverable upon
conversion of the Securities will instead be deliverable in the amount and type of Applicable
Consideration that a holder of that number of shares of the Company’s common stock would have
received in such transaction and (z) the VWAP Price will be calculated based on the value of a unit
of Applicable Consideration that a holder of one share of the Company’s Common Stock would have
received in such transaction; provided that any increase in the Conversion Rate in connection with
a Non-Stock Change of Control under Section 10.05 shall be in effect under this Section 10.07 only
until the close of business on the Fundamental Change Repurchase Date relating to the Non-Stock
Change of Control. If the transaction causes the Common Stock to be converted into, or exchanged
for, or constitute solely the right to receive more than a single type of consideration (determined
based in part upon any form of stockholder election), the Applicable Consideration into which the
Debentures will be convertible or used to calculate the VWAP Price, as the case may be, will be
deemed to be the weighted average of the types and amounts of consideration received by the holders
of Common Stock that affirmatively make such an election. The Company shall notify holders, the
Trustee and the Conversion Agent of that weighted average as soon as practicable after such
determination is made. The Company shall not become a party to any such transaction unless its
terms are consistent with the foregoing. If, in the case of any such reclassification, change,
consolidation, merger, sale, lease, transfer, conveyance or other disposition, the stock or other
securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and assets of a corporation other than the successor or purchasing corporation, as
the case may be, in such reclassification, change, consolidation, merger, sale, lease, transfer,
conveyance or other disposition, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the interests of the
Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason
of the foregoing, including to the extent practicable the provisions providing for the conversion
rights set forth in this Article 10.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Holder, at the address of such Holder as it appears on the register of the Securities
maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

74

 

     The above provisions of this Section 10.07 shall similarly apply to successive
reclassifications, changes, consolidations, mergers, sales, leases, transfers, conveyances or other
dispositions.

     If this Section 10.07 applies to any event or occurrence, Section 10.06 shall not apply.

     Section 10.08. Taxes on Shares Issued. The issue of stock certificates on conversions of
Securities shall be made without charge to the converting Holder of Securities for any documentary,
stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not,
however, be required to pay any such tax which may be payable in respect of any transfer involved
in the issue and delivery of stock in any name other than that of the Holder of any Securities
converted, and the Company shall not be required to issue or deliver any such stock certificate
unless and until the Person or Persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the Company that such tax
has been paid.

     Section 10.09. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock
to provide for the conversion of the Securities, including any Additional Shares, from time to time
as such Securities are presented for conversion.

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

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

     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 in good faith and as expeditiously as possible, to the extent then permitted by
the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such
registration or approval, as the case may be.

75

 

     The Company further covenants that, if at any time the Common Stock shall be listed on The
Nasdaq Global Select Market or any other national securities exchange or automated quotation
system, the Company will, if permitted by the rules of such exchange or automated quotation system,
list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon conversion of the Securities; provided that if the
rules of such exchange or automated quotation system permit the Company to defer the listing of
such Common Stock until the first conversion of the Securities into Common Stock in accordance with
the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon
conversion of the Securities in accordance with the requirements of such exchange or automated
quotation system at such time.

     Section 10.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any Holder of Securities to determine the
Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate,
or with respect to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture provided to be employed,
in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
capital stock, other securities or other assets or property, which may at any time be issued or
delivered upon the conversion of any Securities; and the Trustee and any other Conversion Agent
make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall
be responsible for any failure of the Company to issue, transfer or deliver any shares of Common
Stock or stock certificates or other securities or property or cash upon the surrender of any
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 any Conversion Agent shall be under any responsibility to
determine the correctness of any provisions contained in any supplemental indenture entered into
pursuant to Section 10.07 relating either to the kind or amount of shares of capital stock or other
securities or other assets or property (including cash) receivable by Holders of Securities upon
the conversion of their Securities after any event referred to in such Section 10.07 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 9.01, may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect thereto.

     Section 10.11. Notice to Holders Prior to Certain Actions. In case:

76

 

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 10.06; or

     (b) the Company shall authorize the granting to the Holders of all or substantially all of its
Common Stock or rights or warrants to subscribe for or purchase any share of any class of its
Capital Stock or any other rights or warrants that would require an adjustment in the Conversion
Rate pursuant to Section 10.06;

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

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

then the Company shall cause to be filed with the Trustee and to be mailed to each Holder of
Securities at its address appearing on the Register provided for in Section 2.05 of this Indenture,
as promptly as possible but in any event at least ten calendar days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is
expected to become effective or occur, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, reorganization, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up; provided that a separate notice shall not be
required under this Section if such notice has been effectively provided under another provision of
this Indenture. Failure to give such notice, or any defect therein, shall not affect the legality
or validity of such dividend, distribution, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up.

     Section 10.12. Stockholder Rights Plans. To the extent that any stockholder rights plan
(i.e., a “poison pill”) adopted by the Company is in effect upon conversion of the Security, the
converting Holder shall receive, in addition to any shares of Common Stock issued in connection
with such conversion, the rights under the rights plan, unless prior to such conversion, the rights
plan has terminated or expired, all the rights have been redeemed or the rights have

77

 

separated from the Common Stock. There shall be no adjustment to the Conversion Rate with
respect to the adoption of any such rights plan and the distribution of the rights with respect to
shares of Common Stock, unless rights have separated from the Common Stock. If the rights provided
for in any future rights plan adopted by the Company have separated from the shares of Common Stock
in accordance with the provisions of the applicable stockholder rights agreement so that the
Holders of the Securities would not be entitled to receive any rights in respect of Common Stock
issuable upon conversion of the Securities, the Conversion Rate will be adjusted as provided in
Section 10.06(d), and will be further adjusted in the event of any events affecting such rights
following any separation from the Common Stock and subject to readjustment in the event of the
expiration, termination or redemption of such rights.

     Section 10.13. Settlement Upon Conversion; Cash Percentage Election. (a) Upon any conversion
of Securities, the Company will deliver to converting Holders in respect of each $1,000 principal
amount of Securities being converted a “Settlement Amount” equal to the sum of the Daily Settlement
Amounts for each of the 20 Trading Days during the Conversion Observation Period. Settlement in
cash and shares of Common Stock, if any, will occur no later than the fifth Trading Day following
the final Trading Day of the Conversion Observation Period.

     (b) By the close of business on the Business Day prior to the first Scheduled Trading Day of
the applicable Conversion Observation Period, the Company may specify a percentage of the Daily
Share Amount included in the Daily Settlement Amount that will be settled in cash (the “Cash
Percentage”) and will notify the Holder of such Cash Percentage through written notice to the
Trustee (the “Cash Percentage Notice”). If the Company elects to specify a Cash Percentage, (x)
the amount of cash that the Company will deliver in respect of the Daily Share Amount for each
Trading Day in the applicable Observation Conversion Period will equal the product of: (i) the Cash
Percentage, (ii) the Daily Share Amount for such Trading Day (assuming for this purpose the Company
has not specified a Cash Percentage), and (iii) the VWAP Price for such Trading Day and (y) the
number of shares of Common Stock deliverable in respect of each Trading Day in the applicable
Observation Conversion Period (in lieu of the full Daily Share Amount for such Trading Day) will be
a percentage of the Daily Share Amount (assuming the Company has not specified a Cash Percentage)
equal to 100% minus the Cash Percentage.

     If the Company does not specify a Cash Percentage by the close of business on the Business Day
prior to the scheduled first Trading Day of the applicable Observation Conversion Period, the
Company must settle 100% of the Daily Share Amount for each Trading Day in the applicable
Conversion Observation Period with shares of Common Stock; provided that the Company shall pay cash
in lieu of fractional shares otherwise issuable upon conversion of such Securities.

[FORM OF REVERSE SIDE OF SECURITY]

Nuance Communications, Inc.

2.75% Senior Convertible Debenture Due 2031

1. Interest

     (a) NUANCE COMMUNICATIONS, INC., a Delaware corporation (such corporation, and its successors
and assigns under the Indenture hereinafter referred to, being herein called the “Company”),
promises to pay interest on the principal amount of this Security at the rate of 2.75% per annum.
The Company will pay interest semiannually on May 1 and November 1 of each year commencing on May
1, 2012. Interest on the Security will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from October 24, 2011. Interest will be computed on the
basis of a 360-day year of twelve 30-day months. If a payment date is not a Business Day, payment
will be made on the next succeeding Business Day, and no additional interest will accrue in respect
of such payment by virtue of the payment being made on such later date.

     (b) The Company may elect to pay additional interest on this Security as sole remedy for an
Event of Default relating to a failure to file with the Trustee reports required under the Exchange
Act.

     (c) Except as otherwise specifically set forth, all references herein to “interest” include
additional interest that the Company elects to pay in connection with a failure to file reports
required under the Exchange Act.

2. Paying Agent, Registrar and Conversion Agent

     Initially, U.S. Bank National Association, a national banking association (the “Trustee”),
will act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and change any
Paying Agent, Registrar or co-registrar or Conversion Agent without notice. The Company or any of
its domestically incorporated wholly owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar, or Conversion Agent.

3. Indenture

     The Company issued the Securities under an Indenture dated as of October 24, 2011 (the
“Indenture”), between the Company and the Trustee. The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”).
Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the
Indenture (except as specifically provided in Section 1(b)). The Securities are

 

 

subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a
statement of those terms.

     This Security is one of the Securities referred to in the Indenture issued in an initial
aggregate principal amount of $690,000,000. Additional Securities may be issued in accordance with
the Indenture. The Indenture also imposes limitations on the ability of the Company to consolidate
or merge with or into any other Person or convey, transfer or lease all or substantially all of the
property of the Company.

5. Optional Redemption

     The Securities will not be redeemable at the option of the Company prior to November 6, 2017.
At any time on or after November 6, 2017, the Securities will be redeemable at the option of the
Company, in whole or in part, on not less than 25 Scheduled Trading Days nor more than 60 Business
Days prior notice, at a Redemption Price equal to 100% of the principal amount of the Securities
being redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date.

6. Repurchase of Securities at the Option of Securityholders

     If a Fundamental Change occurs at any time prior to maturity of the Security, this Security
will be subject to a repurchase on the terms and conditions of the Indenture, at the option of the
Holder, on a Fundamental Change Repurchase Date, specified by the Company.

     Subject to the terms and conditions of the Indenture, each Holder shall have the right, at
such Holder’s option, to require the Company to repurchase all or any portion of the Securities
held by such Holder, on November 1, 2017, November 1, 2021 and November 1, 2026.

7. Conversion

     Upon the occurrence of certain events specified in the Indenture and in compliance with the
provisions of the Indenture, on or prior to the close of business on the Business Day immediately
preceding the Maturity Date of this Security, the Holder hereof has the right, at its option, to
convert each $1,000 principal amount of this Security into a combination of cash and Common Stock,
determined as set forth in the Indenture, based on a Conversion Rate of 30.9610 shares of Common
Stock per $1,000 principal amount of Securities, as the same may be adjusted pursuant to the terms
of the Indenture.

8. Denominations, Transfer, Exchange

     The Securities are in registered form without coupons in denominations of $1,000 and whole
multiples of $1,000. A Securityholder may transfer or

 

 

exchange Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Securityholder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or permitted by the
Indenture.

9. Persons Deemed Owners

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

10. Defaults and Remedies

     If an Event of Default (other than an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the outstanding Securities may declare the
principal of and accrued but unpaid interest on all the Securities to be due and payable. If an
Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the
Company occurs, the principal of and interest on all the Securities will become immediately due and
payable without any declaration or other act on the part of the Trustee or any Securityholder.

11. No Recourse Against Others

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

12. Authentication

     This Security shall not be valid until an authorized signatory of the Trustee (or an
authenticating agent) manually signs the certificate of authentication on the other side of this
Security.

13. Abbreviations

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

14. Governing Law

 

 

     THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK.

15. CUSIP and ISIN Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform Securities Identification
Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities and has
directed the Trustee to use CUSIP and ISIN numbers in notices of redemption as a convenience to
Securityholders. No representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     The Company will furnish to any Holder of Securities upon written request and without charge
to the Holder a copy of the Indenture which has in it the text of this Security.
