during the continuance of any Default, upon written request to a Paying Agent, require such Paying
Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing
so, the Paying Agent (other than the Company) shall have no further liability for the money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or interest on any Security and remaining unclaimed for
two years after such principal or interest has become due and payable shall promptly be paid to the
Company or (if then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being

 

 

required to make any such repayment, may at the expense of the Company cause to be published
once, in the New York Times and The Wall Street Journal (national edition), and mail to each such
Holder, notice that such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such notification, publication and mailing, any
unclaimed balance of such money then remaining will promptly be repaid to the Company.

     Section 2.05. Conversion Agent To Hold Money In Trust.

     The Company shall require each Conversion Agent (that is not the Trustee) to agree in writing
that the Conversion Agent will hold in trust for the benefit of Holders or the Trustee all cash and
shares of Common Stock delivered by the Company to the Conversion Agent for the delivery of
amounts due upon conversion, and will notify the Trustee of any default by the Company in making
any such delivery.

     While any such default continues, the Trustee may require a Conversion Agent to deliver all
cash and shares of Common Stock delivered by the Company to it to the Trustee. Upon payment over
to the Trustee, the Conversion Agent (if other than the Company or a Subsidiary) shall have no
further liability in respect of such amounts. If the Company or a Subsidiary acts as Conversion
Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all cash
and shares of Common Stock held by it as Conversion Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Conversion Agent for the
Securities.

     Section 2.06. Lists of Holders of Securities.

     The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders of Securities. The Company shall
furnish or cause the Registrar to furnish to the Trustee (a) semiannually, not more than 10 days
after each Regular Record Date, a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Holders as of such Regular Record Date; and (b) at such other times as
the Trustee may request in writing, within 30 days after receipt by the Company of any such
request, a list of similar form and content to that in subsection (a) hereof as of a date not more
than 15 days prior to the time such list is furnished; provided, however, that if and so long as
the Trustee shall be the Primary Registrar, no such list need be furnished.

     Section 2.07. Transfer and Exchange.

     (a) Subject to compliance with any applicable additional requirements contained in Section
2.13, when a Security is presented to a Registrar with a request to register a transfer thereof or
to exchange such Security for an equal principal amount of Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested if its
requirements for such transactions are met; provided, however, that every Security presented or
surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an
assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A,
and completed in a manner satisfactory to the Registrar and duly executed by the Holder thereof or
its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon
surrender of any Security for registration of transfer or exchange

 

 

at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the
Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s
request. Any exchange or transfer shall be without charge, except that the Company or the
Registrar may require payment of a sum sufficient to cover any transfer tax or similar governmental
charge that may be imposed in relation thereto; provided that this sentence shall not apply to any
exchange pursuant to Section 2.11, 2.13(a), 4.02(d) or 10.06.

     (b) Neither the Company, any Registrar nor the Trustee shall be required to register the
transfer of or exchange any Securities or portions thereof in respect of which a Fundamental Change
Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of
the purchase of a Security in part, the portion thereof not to be purchased).

     (c) All Securities issued upon any transfer or exchange of Securities shall be 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.

     (d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such
information as the Trustee may reasonably require in connection with the delivery by such Registrar
of Securities upon transfer or exchange of Securities.

     (e) Each Holder of a Security agrees to indemnify the Company and the Trustee against any
liability that may result from the registration of transfer, exchange or assignment of such
Holder’s Security in violation of any provision of this Indenture and/or applicable United States
federal or state securities law.

     (f) 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 Security (including any transfers between or
among Agent Members or other beneficial owners of interests in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are expressly required
by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof.

     Section 2.08. Replacement Securities.

     (a) If (1) any mutilated Security is surrendered to the Trustee, or (2) the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security,
and there is delivered to the Company and the Trustee, such security or indemnity, in each case, as
may be required by them to save each of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a protected purchaser, the Company
shall execute and upon a Company Request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a
replacement Security of like tenor and principal amount, bearing a number not contemporaneously
outstanding.

     (b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become
due and payable, or is about to be purchased by the Company pursuant to Article 3, or

 

 

converted pursuant to Article 4, the Company in its discretion may, instead of issuing a new
Security, pay, purchase or convert such Security, as the case may be.

     (c) Upon the issuance of any new Securities under this Section 2.08, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of counsel and the
Trustee) in connection therewith.

     (d) Every new Security issued pursuant to this Section 2.08 in lieu of any mutilated,
destroyed, lost or stolen Security shall constitute an original additional contractual obligation
of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

     (e) The provisions of this Section 2.08 are (to the extent lawful) exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.09. Outstanding Securities.

     (a) Securities outstanding (“Outstanding”) at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those purchased pursuant to Article 3, those converted
pursuant to Article 4, those delivered to the Trustee for cancellation or surrendered for transfer
or exchange and those described in this Section 2.09 as not Outstanding.

     (b) If a Security is replaced pursuant to Section 2.08, such replaced Security ceases to be
Outstanding unless the Company receives proof satisfactory to it that the replaced Security is held
by a protected purchaser.

     (c) If a Paying Agent holds in respect of the Outstanding Securities on a Fundamental Change
Purchase Date or the Final Maturity Date money sufficient to pay the principal of and accrued
interest on Securities (or portions thereof) payable on that date, then on and after such
Fundamental Change Purchase Date or Final Maturity Date, as the case may be, such Securities (or
portions thereof, as the case may be) shall cease to be Outstanding and interest on them shall
cease to accrue.

     (d) Subject to the restrictions contained in Section 2.10, a Security does not cease to be
Outstanding because the Company or an Affiliate of the Company holds the Security.

     Section 2.10. Treasury Securities.

     In determining whether the Holders of the required principal amount of Securities have
concurred in any request, demand, authorization, notice, direction, waiver or consent, Securities
owned by the Company or any other obligor on the Securities or by any Subsidiary of the Company or
of such other obligor shall be disregarded, except that, for purposes of determining whether the
Trustee shall be protected in relying on any such request, demand, authorization, notice,
direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows
are so owned shall be so disregarded.

 

 

     Section 2.11. Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare and execute, and,
upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities but may have
variations that the Company with the consent of the Trustee considers appropriate for temporary
Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate and deliver definitive Securities in exchange for temporary Securities representing an
equal principal amount of Securities. The temporary Securities will be exchanged for definitive
Securities in accordance with Sections 2.07 and 2.13 hereof. Until so exchanged, temporary
Securities shall have the same rights under this Indenture as the definitive Securities.

     Section 2.12. Cancellation.

     The Company at any time may deliver Securities to the Trustee for cancellation. The
Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee any Securities
surrendered to them for transfer, exchange, purchase, payment or conversion. The Trustee and no
one else shall cancel, in accordance with its standard procedures, all Securities surrendered for
transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of the
cancelled Securities in accordance with its customary procedures or deliver the canceled Securities
to the Company upon request. All Securities which are purchased or otherwise acquired by the
Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall be
delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities
or issue any new Securities to replace any such Securities or any Securities that any Holder has
converted pursuant to Article 4. The Trustee shall maintain a record of all canceled Securities.
The Trustee shall provide the Company a list of all Securities that have been canceled from time to
time as requested by the Company in writing.

     Section 2.13. Legend; Additional Transfer and Exchange Requirements.

     (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject
to restrictions on transfer and bearing the legends set forth on the forms of Securities attached
as Exhibit A (collectively, the “Legend”), or if a request is made to remove the Legend on a
Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as
the case may be, unless there is delivered to the Company and the Registrar such satisfactory
evidence, which shall include an Opinion of Counsel if requested by the Company or such Registrar,
as may be reasonably required by the Company and the Registrar, that neither the Legend nor the
restrictions on transfer set forth therein are required to ensure that transfers thereof comply
with the provisions of Rule 144A or Rule 144 under the Securities Act or that such Securities are
not “restricted” within the meaning of Rule 144 under the Securities Act; provided that no such
evidence need be supplied in connection with the sale of such Security pursuant to a registration
statement that is effective at the time of such sale. Upon (1) provision of such satisfactory
evidence if requested or (2) notification by the Company to the Trustee and Registrar of the sale
of such Security pursuant to a registration statement that is effective at the time of such sale,
the Trustee, at the written direction of the Company, shall authenticate and deliver a Security
that does not bear the Legend. If the Legend is removed from the face of a

 

 

Security and the Security is subsequently held by an Affiliate of the Company, the Legend
shall be reinstated.

     (b) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided that the foregoing shall not prohibit any transfer of a Security that
is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until
such Security has been registered in the name of such Person. Notwithstanding any other provisions
of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be
made only in accordance with this Section 2.13.

     (c) Subject to Section 2.13(b) and in compliance with Section 2.13(d), every Security shall be
subject to the restrictions on transfer provided in the Legend. Whenever any Restricted Security
other than a Restricted Global Security is presented or surrendered for registration of transfer or
in exchange for a Security registered in a name other than that of the Holder, such Security must
be accompanied by a certificate in substantially the form set forth in Exhibit A, dated the date of
such surrender and signed by the Holder of such Security, as to compliance with such restrictions
on transfer. The Registrar shall not be required to accept for such registration of transfer or
exchange any Security not so accompanied by a properly completed certificate.

     (d) The restrictions imposed by the Legend upon the transferability of any Security shall
cease and terminate when such Security has been sold pursuant to an effective registration
statement under the Securities Act or transferred in compliance with Rule 144 under the Securities
Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor
provision). Any Security as to which such restrictions on transfer shall have expired in
accordance with their terms or shall have terminated may, upon a surrender of such Security for
exchange to the Registrar in accordance with the provisions of this Section 2.13 (accompanied, in
the event that such restrictions on transfer have terminated by reason of a transfer in compliance
with Rule 144 or any successor provision, by, if requested by the Company or the Registrar, an
Opinion of Counsel reasonably acceptable to the Company and the Registrar and addressed to the
Company and the Registrar, to the effect that the transfer of such Security has been made in
compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like
tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company
shall inform the Trustee of the effective date of any registration statement registering the offer
and sale of the Securities under the Securities Act. The Trustee shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the aforementioned
Opinion of Counsel or registration statement.

     As used in Sections 2.13(c) and (d), the term “transfer” encompasses any sale, pledge,
transfer, hypothecation or other disposition of any Security.

     (e) The provisions below shall apply only to Global Securities:

 

 

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

     (2) Notwithstanding any other provisions of this Indenture or the Securities, a Global
Security shall not be exchanged in whole or in part for a Security registered, and no
transfer of a Global Security in whole or in part shall be registered in the name of any
Person other than the Depositary or one or more nominees thereof; provided that a Global
Security may be exchanged for Securities registered in the names of any person designated by
the Depositary in the event that (A) the Depositary has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a “clearing agency” registered under the Exchange Act, and in either case a
successor Depositary is not appointed by the Company within 90 days after receiving such
notice or becoming aware that the Depositary has ceased to be a “clearing agency” or (B) an
Event of Default has occurred and is continuing with respect to the Securities. Any Global
Security exchanged pursuant to the preceding sentence shall be so exchanged as directed by
the Depositary. Any Security issued in exchange for a Global Security or any portion
thereof shall be a Global Security; provided, however, that any such Security so issued that
is registered in the name of a Person other than the Depositary or a nominee thereof shall
not be a Global Security.

     (3) Securities issued in exchange for a Global Security or any portion thereof that are
not issued as a Global Security shall be issued in definitive, fully registered form,
without interest coupons, shall have a principal amount equal to that of such Global
Security or portion thereof to be so exchanged, shall be registered in such names and be in
such authorized denominations as the Depositary shall designate and shall bear the
applicable legends provided for herein. Any Global Security to be exchanged in whole shall
be surrendered by the Depositary to the Trustee or the Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for
exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with
respect to such Global Security, the principal amount thereof shall be reduced, by an amount
equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made
on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall
authenticate and deliver the Security issuable on such exchange to or upon the order of the
Depositary or an authorized representative thereof.

     (4) Subject to clause (6) of this Section 2.13(e), the registered Holder may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is entitled to take
under this Indenture or the Securities.

     (5) In the event of the occurrence of any of the events specified in clause (2) of this
Section 2.13(e), the Company will promptly make available to the Trustee a reasonable supply
of Certificated Securities in definitive, fully registered form, without interest coupons.

 

 

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

     (7) At such time as all interests in a Global Security have been converted, cancelled
or exchanged for Securities in certificated form, such Global Security shall, upon receipt
thereof, be cancelled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Securities Custodian, subject to Section 2.12 of
this Indenture. At any time prior to such cancellation, if any interest in a Global
Security is converted, canceled 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 Securities Custodian, be
appropriately reduced, and an endorsement shall be made on such Global Security, by the
Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such
reduction.

     (f) Until the expiration of the holding period applicable to sales thereof under Rule 144(k)
under the Securities Act (or any successor provision thereto), any stock certificate representing
Common Stock issued upon conversion of any Security shall bear a legend in substantially the
following form, unless such Common Stock has been sold pursuant to a registration statement that
has been declared effective under the Securities Act (and which continues to be effective at the
time of such transfer) or transferred in compliance with Rule 144 under the Securities Act (or any
successor provision thereto), or such Common Stock has been issued upon conversion of Securities
that have been transferred pursuant to a registration statement that has been declared effective
under the Securities Act or pursuant to Rule 144 under the Securities Act (or any successor
provision thereto), or unless otherwise agreed by the Company in writing with written notice
thereof to the transfer agent:

THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS.
NEITHER THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE NOR ANY INTEREST OR
PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS
EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION UNDER THE SECURITIES ACT.

 

 

BY ITS ACQUISITION HEREOF, THE HOLDER (1) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER
SUCH SHARES PRIOR TO THE DATE WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE
HEREOF AND THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER
OF THE SHARES (THE “RESALE RESTRICTION TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY
SUBSIDIARY THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED
EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SHARES ARE ELIGIBLE FOR RESALE
PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER
AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON
RULE 144A, (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH
OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF
COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND
WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION
DATE.

     Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms or as to which the conditions for removal of the foregoing legend set
forth therein have been satisfied 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 number of shares of Common
Stock, which shall not bear the restrictive legend required by this section.

     Section 2.14. CUSIP Numbers.

     The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally
in use), and, if so, the Trustee shall use “CUSIP” numbers in a Fundamental Change Purchase Notice
as a convenience to Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as contained in any
Fundamental Change Purchase Notice and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such purchase shall not be affected by any defect in or
omission of such numbers. The Company will notify the Trustee in writing of any change in the
“CUSIP” numbers.

     Section 2.15. Calculations.

     Except as otherwise specifically stated herein or in the Securities, all calculations to be
made in respect of the Securities shall be the obligation of the Company. All calculations made by
the Company or its agent as contemplated pursuant to the terms hereof and of the Securities shall
be made in good faith and be final and binding on the Holders absent manifest error. The

 

 

Company shall provide a schedule of calculations to the Trustee, and the Trustee shall be
entitled to rely upon the accuracy of the calculations by the Company without independent
verification. The Trustee shall forward calculations made by the Company to any holder of
Securities upon request.

     Section 2.16. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly provided for, on the
Stated Maturity of such interest shall be paid to the Person in whose name the Security is
registered at the close of business on the Regular Record Date for such interest payment.

     Any interest on any Security which is payable, but is not punctually paid or duly provided
for, on the Stated Maturity of such interest, and interest on such defaulted interest at the then
applicable interest rate borne by the Securities, to the extent lawful (such defaulted interest and
interest thereon herein collectively called “Defaulted Interest”), shall forthwith cease to be
payable to the Holder on the Regular Record Date; and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Subsection (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Securities are registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest, which shall be fixed in the following manner. The Company
shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security and the date (not less than 20 days after such notice) of the proposed payment (the
“Special Payment Date”), and on the date of payment the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the
Special Payment Date, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this subsection provided. Thereupon the Trustee shall
fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than
15 days and not less than 10 days prior to the date of the Special Payment Date and not less than
10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company in writing of such Special Record Date. Unless the Company issues a
press release to the same effect, in the name and at the expense of the Company, the Trustee shall
cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in
the Security Register, not less than 10 days prior to such Special Record Date or notify in such
other manner as the Trustee determines, including in accordance with any Applicable Procedures.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special
Payment Date therefor having been so mailed or otherwise conveyed, such Defaulted Interest shall be
paid to the Persons in whose names the Securities are registered on such Special Record Date and
shall no longer be payable pursuant to the following paragraph (b).

     (b) The Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any national securities exchange on which the Securities may
be listed, and upon such notice as may be required by this Indenture not inconsistent with the
requirements of such exchange, if, after written notice given by the

 

 

Company to the Trustee of the proposed payment pursuant to this subsection, such payment shall
be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 2.16, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     Section 2.17. Computation of Interest.

     Interest on the Securities shall be computed on the basis of a 360-day year comprised of
twelve 30-day months.

ARTICLE 3

PURCHASE

     Section 3.01. Purchase of Securities by the Company for Cash at Option of the Holder Upon
a Fundamental Change.

     (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security
shall have the right, at the option of the Holder, to require the Company to purchase for cash in
whole or in part (in principal amounts of $1,000 and integral multiples thereof) the Securities of
such Holder at the Fundamental Change Purchase Price on the date specified by the Company that is
not less than 30 days and not more than 45 days after the Issuer Fundamental Change Notice (the
“Fundamental Change Purchase Date”).

     (b) Not later than 30 days after the occurrence of a Fundamental Change, the Company shall
mail a written notice of the Fundamental Change and of the resulting purchase right to the Trustee,
Paying Agent and to each Holder of record of Securities (an “Issuer Fundamental Change Notice”).
The Issuer Fundamental Change Notice shall include the form of a Fundamental Change Purchase Notice
(defined below) to be completed by the Holder and shall state:

     (1) the events causing such Fundamental Change;

     (2) the date (or expected date) of such Fundamental Change;

     (3) the last date by which the Fundamental Change Purchase Notice must be delivered to
elect the purchase option pursuant to this Section 3.01;

     (4) the Fundamental Change Purchase Date;

     (5) the Fundamental Change Purchase Price;

     (6) the Holder’s right to require the Company to purchase the Securities;

 

 

     (7) the name and address of each Paying Agent and Conversion Agent;

     (8) the then effective Conversion Rate and any adjustments to the Conversion Rate
resulting from such Fundamental Change;

     (9) the procedures that the Holder must follow to exercise rights under Article 4 of
this Indenture and that the Securities as to which a Fundamental Change Purchase Notice has
been given may be converted into Common Stock pursuant to Article 4 of this Indenture only
to the extent that the Fundamental Change Purchase Notice has been withdrawn in accordance
with the terms of this Indenture;

     (10) the procedures that the Holder must follow to exercise rights under this Section
3.01;

     (11) the procedures for withdrawing a Fundamental Change Purchase Notice;

     (12) that, unless the Company fails to pay such Fundamental Change Purchase Price,
Securities covered by any Fundamental Change Purchase Notice will cease to be outstanding
and interest will cease to accrue on and after the Fundamental Change Purchase Date; and

     (13) the CUSIP number of the Securities.

     At the Company’s written request, the Trustee shall give such Issuer Fundamental Change Notice
in the Company’s name and at the Company’s expense; provided that, in all cases, the text of such
Issuer Fundamental Change Notice shall be prepared by the Company. In connection with the delivery
of the Issuer Fundamental Change Notice to the Holders, the Company shall publish a notice
containing substantially the same information that is required in the Issuer Fundamental Change
Notice in a newspaper of general circulation in the City of New York or publish information on a
website of the Company or through such other public medium the Company may use at that time. If
any of the Securities is in the form of a Global Security, then the Company shall modify such
notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of
Global Securities.

     The Trustee shall be under no obligation to ascertain the occurrence of a Fundamental Change
or to give notice with respect thereto. The Trustee may conclusively assume, in absence of written
notice to the contrary from the Company, that no Fundamental Change has occurred.

     (c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a written
notice (which shall be in substantially the form set forth in the form of Security attached as
Exhibit A under the heading “Fundamental Change Purchase Notice” and which may be delivered by
letter, overnight courier, hand delivery, facsimile transmission or in any other written form and,
in the case of Global Securities, may be delivered electronically or by other means in accordance
with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change
Purchase Notice”) to the Paying Agent at any time prior to the close of business on the Business
Day prior to the Fundamental Change Purchase Date, subject to extension to comply with applicable
law.

 

 

     (1) The Fundamental Change Purchase Notice shall state: (A) if the Securities are in
certificated form, the certificate numbers of the Securities which the Holder will deliver
to be purchased (or, if the Security is held in global form, any other items required to
comply with the Applicable Procedures), (B) the portion of the principal amount of the
Securities which the Holder will deliver to be purchased, which portion must be a principal
amount of $1,000 or any integral multiple thereof and (C) that such Security shall be
purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions
specified in the Securities and in this Indenture.

     (2) The delivery of a Security for which a Fundamental Change Purchase Notice has been
timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the
Fundamental Change Purchase Date (together with all necessary endorsements) at the office of
such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental
Change Purchase Price therefore.

     (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01, a
portion of a Security if the principal amount of such portion is $1,000 or an integral
multiple thereof. Provisions of this Indenture that apply to the purchase of all of a
Security also apply to the purchase of such portion of such Security.

     (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying
Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have
the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion
thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time
prior to the close of business on the Business Day prior to the Fundamental Change Purchase
Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with
Section 3.02(b).

     (5) A Paying Agent shall promptly notify the Company of the receipt by it of any
Fundamental Change Purchase Notice or written withdrawal thereof.

     (6) Anything herein to the contrary notwithstanding, in the case of Global Securities,
any Fundamental Change Purchase Notice may be delivered or withdrawn and such Securities may
be surrendered or delivered for purchase in accordance with the Applicable Procedures as in
effect from time to time.

     Section 3.02. Effect of Fundamental Change Purchase Notice.

     (a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Purchase
Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change
Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as
specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Purchase
Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such
Holder promptly following the later of (1) the Fundamental Change Purchase Date (provided that the
conditions in Section 3.01 have been satisfied) or (2) the time of delivery of such Security to a
Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in
respect of which a Fundamental Change Purchase Notice has been

 

 

given by the Holder thereof may not be converted in accordance with the provisions of Article
4 on or after the date of the delivery of such Fundamental Change Purchase Notice unless such
Fundamental Change Purchase Notice has first been validly withdrawn in accordance with Section
3.02(b) with respect to the Securities to be converted.

     (b) A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which
may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other
written form and, in the case of Global Securities, may be delivered electronically or by other
means in accordance with the Applicable Procedures) of withdrawal delivered by the Holder to a
Paying Agent prior to the close of business on the Business Day prior to the Fundamental Change
Purchase Date, specifying (1) the principal amount of the Security or portion thereof (which must
be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect
to which such notice of withdrawal is being submitted, (2) if the Securities are in certificated
form, the certificate numbers of the Security being withdrawn in whole or in part and (3) the
portion of the principal amount of the Security that will remain subject to the Fundamental Change
Purchase Notice, which portion must be a principal amount of $1,000 or an integral multiple
thereof.

     Section 3.03. Deposit of Fundamental Change Purchase Price.

     (a) On or before 10:00 a.m. New York City time on the applicable Fundamental Change Purchase
Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an
Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of money (in immediately available funds if deposited on or
after such Fundamental Change Purchase Date), sufficient to pay the aggregate Fundamental Change
Purchase Price of all the Securities or portions thereof that are to be purchased as of the
Fundamental Change Purchase Date.

     (b) If the Paying Agent holds on the Fundamental Change Purchase Date in accordance with the
terms hereof an amount of money sufficient to pay the Fundamental Change Purchase Price of any
Security (or portion thereof) for which a Fundamental Change Purchase Notice has been tendered and
not withdrawn in accordance with this Indenture then, immediately following the applicable
Fundamental Change Purchase Date, whether or not the Security is delivered to the Paying Agent,
such Security shall cease to be outstanding, interest on such Security, shall cease to accrue, and
the rights of the Holder of such Security shall terminate (other than the right to receive the
Fundamental Change Purchase Price upon delivery of the Security as aforesaid).

     (c) The Paying Agent will promptly return to the respective Holders thereof any Securities
with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with
this Indenture.

     (d) If a Fundamental Change Purchase Date falls after a Regular Record Date and on or before
the related Interest Payment Date, then interest on the Securities payable on such Interest Payment
Date will be payable to the Holders in whose names the Securities are registered at the close of
business on such Regular Record Date.

 

 

     Section 3.04. Repayment to the Company.

     To the extent that the aggregate amount of cash deposited by the Company pursuant to Section
3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof
that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date
the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the
Company, or if such money is then held by the Company in trust, it shall be discharged from the
trust.

     Section 3.05. Securities Purchased In Part.

     Any Security that is to be purchased only in part shall be surrendered at the office of a
Paying Agent, and promptly after the Fundamental Change Purchase Date, as the case may be, the
Company shall execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge, a new Security or Securities, of such authorized denomination or
denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or
any integral multiple thereof), in aggregate principal amount equal to, and in exchange for, the
portion of the principal amount of the Security so surrendered that is not purchased.

     Section 3.06. Compliance With Securities Laws Upon Purchase of Securities.

     In connection with any offer to purchase Securities under Section 3.01, the Company shall (a)
comply with the provisions of the tender offer rules under the Exchange Act which may then be
applicable, (b) file the related Schedule TO (or any successor or similar schedule, form or report)
if required under the Exchange Act, and (c) otherwise comply with all federal and state securities
laws in connection with such offer to purchase or purchase of Securities, all so as to permit the
rights of the Holders and obligations of the Company under Sections 3.01 through 3.04 to be
exercised in the time and in the manner specified therein. To the extent that compliance with any
such laws, rules and regulations would result in a conflict with any of the terms hereof, this
Indenture is hereby modified to the extent required for the Company to comply with such laws, rules
and regulations.

     Section 3.07. Purchase of Securities In Open Market.

     The Company may purchase Securities in the open market or by tender at any price or pursuant
to private agreements. The Company shall surrender any Security purchased by the Company pursuant
to this Article 3 to the Trustee for cancellation. Any Securities surrendered to the Trustee for
cancellation may not be reissued or resold by the Company and will be canceled promptly in
accordance with Section 2.12.

 

 

ARTICLE 4

CONVERSION

     Section 4.01. Conversion Privilege and Conversion Rate.

     (a) Any Security or portion thereof that is an integral multiple of $1,000 principal amount
may be converted by the Holder thereof in accordance with the provisions of this Article 4. Upon
conversion, Holders shall be entitled to receive the amount of cash and, if applicable, shares of
Common Stock determined in the manner provided in Section 4.12. Securities may be converted prior
to the close of business on the second Business Day preceding the Final Maturity Date at the
Conversion Rate in effect at the time of such conversion only under the following circumstances:

     (1) on any Business Day in any calendar quarter of the Company commencing at any time
after September 30, 2007, and only during such calendar quarter, if, as of the last day of
the immediately preceding calendar quarter, the Closing Price of the Common Stock for at
least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last
Trading Day of such preceding calendar quarter was more than 130% of the applicable
Conversion Price on the last day of such preceding calendar quarter;

     (2) on any Business Day during the five Business Day period after any five consecutive
Trading Day period in which the Trading Price per $1,000 principal amount of Securities, as
determined by the Trustee following a request by a Holder in accordance with the procedures
described in Section 4.01(d)(ii), for each Trading Day of that period was less than 98% of
the product of the Closing Price of the Common Stock on such day and the then applicable
Conversion Rate per $1,000 principal amount of Securities.

     (3) if the Company distributes to all holders of Common Stock any rights entitling them
to purchase, for a period expiring within 45 days of distribution, Common Stock, or
securities convertible into Common Stock, at less than, or having a conversion price per
share less than, the Closing Price of the Common Stock on the Trading Day immediately
preceding the declaration date for such distribution;

     (4) if the Company distributes to all holders of Common Stock assets, cash, debt
securities or rights to purchase the Company’s securities, which distribution has a per
share value as determined by the Board of Directors exceeding 15% of the Closing Price of
the Common Stock on the Trading Day immediately preceding the declaration date for such
distribution;

     (5) if a Fundamental Change occurs; or

     (6) at any time during the period beginning on June 15, 2012 and ending at the close of
business on the second Business Day preceding the Final Maturity Date.

     (b) In the case of a distribution contemplated by clauses (3) and (4) of Section 4.01(a), the
Company shall notify Holders and the Trustee at least 35 days prior to the ex-

 

 

dividend date (defined below) 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 the close of business on the Business Day prior to the ex-dividend
date or the Company’s announcement that such distribution will not take place. In the event of a
distribution contemplated by clauses (3) and (4) of Section 4.01(a), Holders may not convert the
Securities if the Holders will otherwise participate in such distribution on an as converted basis.
The “ex-dividend date” is the first date upon which a sale of the Common Stock does not
automatically transfer the right to receive the relevant distribution from the seller of the Common
Stock to its buyer. The Company will provide written notice to the Conversion Agent as soon as
reasonably practicable of any anticipated or actual event or transaction that will cause or causes
the Securities to become convertible pursuant to clauses (3) or (4) of Section 4.01(a).

     (c) In the case of a Fundamental Change, the Company shall provide notice thereof to the
Holders of Securities and the Trustee at least 15 days prior to the date that is anticipated to be
the Fundamental Change Effective Date of any Fundamental Change that the Company knows or
reasonably should know will occur. If the Company does not know, and should not reasonably know,
that a Fundamental Change will occur until a date that is within 15 days before the anticipated
Fundamental Change Effective Date, the Company will notify the Holders of Securities and the
Trustee promptly after the Company has knowledge of the Fundamental Change. Holders may surrender
Securities for conversion at any time beginning 15 days before the date that is anticipated to be
the Fundamental Change Effective Date and until the Trading Day prior to the Fundamental Change
Purchase Date.

     (d) (i) For each calendar quarter of the Company, beginning with the calendar quarter ending
September 30, 2007, the Company will determine, on the first Business Day following the last
Trading Day of such calendar quarter, whether the Securities are convertible pursuant to clause (1)
of Section 4.01(a), and, if so, will notify the Trustee and the Conversion Agent (to the extent the
Trustee is not also serving as the Conversion Agent) in writing.

     (ii) The Trustee shall have no obligation to determine the Trading Price of the
Securities unless the Company has requested such determination and the Company shall have no
obligation to make such request unless a Holder of the Securities provides the Company with
reasonable evidence that the Trading Price per $1,000 principal amount of Securities would
be less than 98% of the product of the Closing Price of the Common Stock and the then
applicable Conversion Rate per $1,000 principal amount of Securities. At such time, the
Company shall instruct the Trustee to determine the Trading Price of the Securities
beginning on the next Trading Day and on each successive Trading Day until the Trading Price
per $1,000 principal amount of the Securities is greater than 98% of the product of the
Closing Price of the Common Stock and the then applicable Conversion Rate per $1,000
principal amount of the Securities.

     (e) The conversion rights pursuant to this Article 4 shall commence on the Issue Date of the
Securities and expire at the close of business on the second Business Day immediately preceding the
Final Maturity Date, but shall be exercisable only during the time periods specified with respect
to each circumstance pursuant to which the Securities become convertible, subject, in the case of
conversion of any Global Security, to any Applicable Procedures.

 

 

     (f) Securities in respect of which a Fundamental Change Purchase Notice has been delivered, if
otherwise convertible pursuant to this Article 4, may not be surrendered for conversion pursuant to
this Article 4 prior to a valid withdrawal of such Fundamental Change Purchase Notice, in
accordance with the provisions of Article 3.

     (g) Provisions of this Indenture that apply to conversion of all of a Security also apply to
conversion of a portion of a Security.

     (h) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(i)
and Section 4.06.

     (i) If a Fundamental Change occurs prior to the Final Maturity Date as a result of a
transaction described in clauses (1), (2) or (4) of the definition of the term “Change of Control”
(giving effect to the last paragraph of such definition) and a Holder elects to convert its
Securities “in connection with” such transaction, the Company shall pay a “Make Whole Premium” by
increasing the applicable Conversion Rate for the Securities surrendered for conversion by a number
of additional shares of Common Stock as provided in this Section 4.01(i) (the “Additional Shares”).
A conversion of Securities shall be deemed for these purposes to be “in connection with” such a
transaction if the notice of conversion is received by the Conversion Agent from and including the
Fundamental Change Effective Date and prior to the close of business on the Business Day prior to
the Fundamental Change Purchase Date.

     The number of Additional Shares per $1,000 principal amount of Securities constituting the
Make Whole Premium shall be determined by reference to the table below and shall be based on the
date on which the Fundamental Change Effective Date occurs and the price (the “Stock Price”) paid,
or deemed to be paid, per share of Common Stock in such transaction. If holders of Common Stock
receive only cash in the Fundamental Change transaction, the Stock Price shall be the cash amount
paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing
Prices of the Common Stock for each of the ten consecutive Trading Days prior to but excluding the
Fundamental Change Effective Date.

     The following table sets forth the Additional Share amounts, if any, by which the applicable
Conversion Rate shall be increased for each Stock Price and Fundamental Change Effective Date.

     If the actual Stock Price or Fundamental Change Effective Date is not set forth in the table
above, then:

     (i) if the actual Stock Price on the Fundamental Change Effective Date is between two
Stock Price amounts in the table or the actual Fundamental Change Effective Date is between
two Fundamental Change Effective Dates in the table, the Additional Share amounts will be
determined by a straight-line interpolation between the Additional Share amounts set forth
for the higher and lower Stock Prices and the two Fundamental Change Effective Dates on the
table, as applicable, based on a 365-day year;

     (ii) if the actual Stock Price on the Fundamental Change Effective Date exceeds $120.00
per share of Common Stock, subject to adjustment as set forth herein, no adjustment to the
Conversion Rate shall be made; and

     (iii) if the actual Stock Price on the Fundamental Change Effective Date is less than
$34.57 per share of Common Stock, subject to adjustment as set forth herein, no adjustment
to the Conversion Rate shall be made.

     The Stock Prices set forth in the first column of the table above will be adjusted as of any
date on which the Conversion Rate of the Securities is adjusted pursuant to Section 4.06 hereof.
The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such
adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is
the Conversion Rate as so adjusted. The number of Additional Share amounts set forth in the table
above will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06
hereof.

     Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 28.9268 shares per
$1,000 principal amount of Securities, subject to adjustment in the manner set forth in subsections
(a) through (e) of Section 4.06 hereof.

 

 

     Section 4.02. Conversion Procedure.

     (a) To convert a Security, a Holder must (1) complete and manually sign the conversion notice
on the back of the Security (which shall be substantially in the form set forth in the form of
Security attached as Exhibit A under the heading “Conversion Notice”) and deliver such notice to
the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate
endorsements and transfer documents if required by the Conversion Agent, (4) pay an amount equal to
the interest payable on the next Interest Payment Date if and as required by Section 4.02(c) and
(5) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the
Holder of a Security satisfies all of the foregoing requirements is the “Conversion Date” with
respect to such Security. Upon the conversion of a Security, the Company shall deliver the amounts
determined in accordance with Section 4.12 which shall be owing upon such conversion on the third
Business Day following the last Trading Day of such Conversion Reference Period. Anything herein
to the contrary notwithstanding, in the case of Global Securities, Securities may be surrendered in
accordance with the Applicable Procedures of the Depositary as in effect from time to time.

     (b) A Holder shall not be entitled to any rights of a holder of Common Stock until such holder
has converted its Securities and received upon conversion thereof shares of Common Stock. The
person in whose name any certificate or certificates for shares of Common Stock shall be issuable
upon such conversion, if any, shall become on the date any such certificate or certificates are
delivered to such holder in accordance with the provisions of this Article 4, the holder of record
of the shares represented thereby. Except as set forth in this Indenture, no payment or adjustment
will be made for dividends or distributions declared or made on shares of Common Stock issued upon
conversion of a Security prior to the issuance of such shares of Common Stock.

     (c) Holders of Securities surrendered for conversion (in whole or in part) during the period
from the close of business on any Regular Record Date to the opening of business on the next
succeeding Interest Payment Date will receive the semiannual interest payable on such Securities on
the corresponding Interest Payment Date notwithstanding the conversion, and such interest shall be
payable on the corresponding Interest Payment Date to the Holder of the Security as of the close of
business on the Regular Record Date. Upon surrender of any such Securities for conversion after
the close of business on such Regular Record Date, such Securities shall also be accompanied by
payment by the Holders of such Securities in funds to the Conversion Agent acceptable to the
Company of an amount equal to the interest payable on such corresponding Interest Payment Date;
provided that no such payment need be made: (1) in connection with a conversion following the
Regular Record Date preceding the Final Maturity Date; (2) if the Company has specified a
Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date , in which case accrued and unpaid interest to, but excluding,
the Fundamental Change Purchase Date shall be paid on such Interest Payment Date to the record
holder as of the Regular Record Date. Each payment of cash interest on the Securities will include
interest accrued for the period commencing on and including the immediately preceding Interest
Payment Date (or, if no interest has been paid, the date the Securities are originally issued)
through the day before the applicable interest payment date (or Fundamental Change Purchase Date);
or (3) to the extent of any overdue interest, if any overdue interest exists at the time of
conversion with respect to such

 

 

Security. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will
be made for accrued and unpaid interest on a converted Security. Accrued and unpaid interest shall
be deemed paid in full, rather than cancelled, extinguished or forfeited. The Company shall not be
required to convert any Securities which are surrendered for conversion without payment of interest
as required by this Section 4.02(c).

     (d) In the case of any Security which is converted in part only, upon such conversion the
Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, without
service charge, a new Security or Securities of authorized denominations in an aggregate principal
amount equal to, and in exchange for, the unconverted portion of the principal amount of such
Security.

     (e) Upon the Company’s determination that Holders are or will be entitled to convert their
Securities in accordance with the provisions of this Article 4, the Company shall promptly issue a
press release or otherwise publicly disclose this information and use its reasonable efforts to
post such information on the Company’s website.

     Section 4.03. Fractional Shares.

     The Company will not issue fractional shares of Common Stock 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. In lieu of any fractional shares, the Company shall pay an amount in cash
equal to the applicable portion of the arithmetic average of the Volume Weighted Average Price of
the Common Stock for each of the 40 consecutive Trading Days of the Conversion Reference Period,
rounding to the nearest whole cent.

     Section 4.04. Taxes on Conversion.

     The issue of stock certificates, if any, on conversion of Securities shall be made without
charge to the converting Holder 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 Security 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 4.05. Company To Provide Common Stock.

     (a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as
may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of
shares of Common Stock to permit the conversion of all outstanding Securities in accordance with
the provisions of this Indenture.

     (b) All shares of Common Stock delivered upon conversion of the Securities shall be newly
issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and

 

 

nonassessable and shall be free from preemptive or similar rights and free of any lien or
adverse claim as the result of any action by the Company.

     (c) The Company will endeavor promptly to comply with all federal and state securities laws
regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any,
and will list or cause to have listed such shares of Common Stock on the New York Stock Exchange,
or each national securities exchange or over the counter market or such other market on which the
Common Stock is then listed or quoted.

     Section 4.06. Adjustment of Conversion Rate.

     The Conversion Rate shall be adjusted from time to time by the Company as follows:

     (a) If the Company issues Common Stock as a dividend or distribution on Common Stock to all
holders of Common Stock, or if the Company effects a share split or share combination, the
Conversion Rate will be adjusted based on the following formula:

     CR1 = CR0 x OS1/OS0

     where

     CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

     CR1 = the new Conversion Rate in effect taking such event into account

     OS0 = the number of shares of Common Stock outstanding immediately prior to such event

     OS1 = the number of shares of Common Stock outstanding immediately after such event.

     Any adjustment made pursuant to this Section 4.06(a) shall become effective on the date that is
immediately after (x) the ex-dividend date for such distribution or (y) the date on which such
split or combination becomes effective, as applicable. If any dividend or distribution described
in this clause Section 4.06(a) is declared but not so paid or made, the new Conversion Rate shall
be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

     (b) If the Company issues to all holders of Common Stock any rights, warrants, options or
other securities entitling them for a period of not more than 45 days after the date of issuance
thereof to subscribe for or purchase Common Stock, or if the Company issues to all holders of
Common Stock securities convertible into Common Stock for a period of not more than 45 days after
the date of issuance thereof, in either case at an exercise or a conversion price per share of
Common Stock less than the Closing Price of the Common Stock on the Business Day immediately
preceding the time of announcement of such issuance, the Conversion Rate will be adjusted based on
the following formula:

     CR1 = CR0 x (OS0+X)/(OS0+Y)

 

 

     where

     CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

     CR1 = the new Conversion Rate taking such event into account

     OS0 = the number of shares of Common Stock outstanding immediately prior to such event

	 	 	 	 	 
	 

	 	X =
	 	the total number of shares of Common Stock issuable pursuant to such rights,
warrants, options, other securities or convertible securities
	 
	 	 	 	 
	 

	 	Y =
	 	the number of shares of Common Stock equal to the quotient of (A) the
aggregate price payable to exercise such rights, warrants, options, other securities or
convertible securities divided by (B) the average of the Closing Prices of the Common
Stock for the 10 consecutive Trading Days prior to the Business Day immediately
preceding the date of announcement for the issuance of such rights, warrants, options,
other securities or convertible securities.

     For purposes of this Section 4.06(b), in determining whether any rights, warrants, options,
other securities or convertible securities entitle the holders to subscribe for or purchase, or
exercise a conversion right for, Common Stock at less than the applicable Closing Price of the
Common Stock, and in determining the aggregate exercise or conversion price payable for such Common
Stock, there shall be taken into account any consideration received by the Company for such rights,
warrants, options, other securities or convertible securities 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 of the Company. Any adjustment made pursuant to this Section 4.06(b) shall
become effective on the ex-dividend date for the distribution. If any right, warrant, option,
other security or convertible security described in this Section 4.06(b) is not exercised or
converted prior to the expiration of the exercisability or convertibility thereof, the new
Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such
right, warrant, option, other security or convertible security had not been so issued.

     (c) If the Company distributes capital stock, evidences of indebtedness or other assets or
property of the Company to all holders of Common Stock, excluding:

     (1) dividends, distributions, rights, warrants, options, other securities or
convertible securities referred to in Section 4.06(a) or (b) above,

     (2) dividends or distributions paid exclusively in cash, and

     (3) Spin-Offs described below in this Section 4.06(c),

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

     CR1 = CR0 x SP0/(SP0-FMV)

 

 

     where

     CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

     CR1 = the new Conversion Rate taking such event into account

     SP0 = the Closing Price of the Common Stock on the Trading Day immediately preceding the
ex-dividend date for such distribution

     FMV = the fair market value (as determined in good faith by the Board of Directors of the
Company) of the capital stock, evidences of indebtedness, assets or property distributed with
respect to each outstanding share of Common Stock on the earlier of the record date or the
ex-dividend date for such distribution.

     An adjustment to the Conversion Rate made pursuant to this paragraph shall be made
successively whenever any such distribution is made and shall become effective on the ex-dividend
date for such distribution.

     If the Company distributes to all holders of Common Stock capital stock of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit of the
Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on
the date fixed for determination of holders of Common Stock entitled to receive such distribution
will be adjusted based on the following formula:

     CR1 = CR0 x (FMV0+MP0)/MP0

     where

     CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

     CR1 = the new Conversion Rate taking such event into account

     FMV0 = the average of the Closing Prices of the capital stock or similar equity interest
distributed to holders of Common Stock applicable to one share of Common Stock over the first 10
consecutive Trading Days after the effective date of the Spin-Off

     MP0 = the average of the Closing Prices of the Common Stock over the first 10 consecutive
Trading Days after the effective date of the Spin-Off.

     An adjustment to the Conversion Rate made pursuant to this paragraph will occur after the
close of business on the 10th consecutive Trading Day after the effective date of the Spin-Off;
provided that in respect of any conversion within the 10 consecutive Trading Days immediately
following the effective date of any Spin-Off, references in this clause 4.06(c) with respect to 10
consecutive Trading Days shall be deemed replaced with such lesser number of consecutive Trading
Days as have elapsed.

 

 

     If any such dividend or distribution described in this Section 4.06(c) is declared but not
paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared.

     (d) If the Company pays or makes any dividend or distribution consisting exclusively of cash
to all holders of Common Stock, the Conversion Rate will be adjusted based on the following
formula:

	 	 	 	 	 	 	 
	 

	 	CR1 = CR0 X
	 	SP0 - T
	 	 
	 

	 	 	 	 	 
	 

	 	 	SP0 - C	 	 

     where

	 	 	 	 	 
	 

	 	CR0 =
	 	the Conversion Rate in effect immediately prior to
the adjustment relating to such event
	 
	 	 	 	 
	 

	 	CR1 =
	 	the new Conversion Rate taking such event into account
	 
	 	 	 	 
	 

	 	SP0 =
	 	the Closing Price of the Common Stock on the Trading
Day immediately preceding the ex-dividend date for
such distribution
	 
	 	 	 	 
	 

	 	T =
	 	the dividend threshold amount, which shall initially
be $0.06 per fiscal quarter, adjusted as described
below to take into account events that cause
adjustments to the Conversion Rate and as further
adjusted to account for any change in the frequency
of payment of the Company’s regular dividend;
provided that the dividend threshold amount shall be
deemed to be zero if the dividend is not a regularly
scheduled dividend
	 
	 	 	 	 
	 

	 	C =
	 	the amount in cash per share that the Company
distributes to holders of its Common Stock.

     An adjustment to the Conversion Rate made pursuant to this Section 4.06(d) shall become
effective on the ex-dividend date for such dividend or distribution. If any dividend or
distribution described in this Section 4.06(d) is declared but not so paid or made, the new
Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared.

     If the Company fails to pay a cash dividend or distribution for a period in which a regularly
scheduled dividend has in prior periods been paid in accordance with past practice, the Conversion
Rate shall be adjusted using the formula in this Section 4.06(d), with the ex-dividend date being
deemed to be the third trading day in the second month of the fiscal quarter in question, and “C”
being deemed to be zero.

     Whenever the Conversion Rate is adjusted, the dividend threshold amount shall be adjusted by
multiplying such dividend threshold amount by a fraction, the numerator of which is the Conversion
Rate prior to adjustment and the denominator of which is the Conversion Rate following such
adjustment.

 

 

     (e) If the Company or any of its subsidiaries makes a payment in respect of a tender offer or
exchange offer for Common Stock to the extent that the cash and value of any other consideration
included in the payment per share of Common Stock exceeds the Closing Price of the Common Stock on
the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to
such tender or exchange offer (the “Expiration Time”), the Conversion Rate will be adjusted based
on the following formula:

     CR1 = CR0 x (AC + (SP1 x OS1))/(SP1 x OS0)

     where

	 	 	 	 	 
	 

	 	CR0 =
	 	the Conversion Rate in effect immediately prior to the adjustment relating to
such event
	 
	 	 	 	 
	 

	 	CR1 =
	 	the new Conversion Rate taking such event into account
	 
	 	 	 	 
	 

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

	 	OS0 =
	 	the number of shares of Common Stock outstanding immediately prior to the
date such tender or exchange offer expires
	 
	 	 	 	 
	 

	 	OS1 =
	 	the number of shares of Common Stock outstanding immediately after such
tender or exchange offer expires (after giving effect to the purchase or exchange of
shares pursuant to such tender or exchange offer)

     SP1 = the average of the Closing Prices of Common Stock for the 10 consecutive Trading Days
commencing on the Trading Day next succeeding the date such tender or exchange offer expires.

     If the application of the foregoing formula would result in a decrease in the Conversion Rate,
no adjustment to the Conversion Rate will be made.

     Any adjustment to the Conversion Rate made pursuant to this Section 4.06(e) shall become
effective on the date immediately following the determination of the average of the Closing Prices
of Common Stock for purposes of SP1 above. If the Company or one of its subsidiaries is obligated
to purchase Common Stock pursuant to any such tender or exchange offer but is permanently prevented
by applicable law from effecting any such purchase or all such purchases are rescinded, the new
Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such
tender or exchange offer had not been made.

     (f) Notwithstanding the foregoing subsections (a) through (e) of this Section 4.06, the
Conversion Rate shall not exceed 28.9268 shares per $1,000 principal amount of Securities, other
than on account of adjustments to the Conversion Rate in the manner set forth in subsections (a)
through (e) of this Section 4.06.

 

 

     (g) In addition to the adjustments pursuant to clauses (a) through (e) above, the Company may,
in its sole discretion, increase the Conversion Rate in order to avoid or diminish any U.S. federal
income tax to holders of Common Stock resulting from any dividend or distribution of capital shares
(or rights to acquire Common Stock) or from any event treated as such for U.S. federal income tax
purposes. The Company may also, from time to time, to the extent permitted by applicable law,
increase the Conversion Rate by any amount for any period if the Company has determined that such
increase would be in the best interests of the Company. If the Company makes such determination,
it will be conclusive and the Company will mail to holders of the Securities a notice of the
increased Conversion Rate and the period during which it will be in effect at least fifteen (15)
days prior to the date the increased Conversion Rate takes effect in accordance with applicable
law.

     (h) If the Company has in effect a rights plan while any Securities remain outstanding, then,
in lieu of any adjustment required pursuant to clauses (a) through (e) of this Section 4.06,
Holders will receive, upon a conversion of Securities in respect of which the Company is required
to deliver shares of Common Stock, in addition to such shares of Common Stock, rights under the
Company’s stockholder rights agreement unless, prior to conversion, the rights have expired,
terminated or been redeemed or unless the rights have separated from the Common Stock. If the
rights provided for in the rights plan adopted by the Company have separated from the Common Stock
in accordance with the provisions of the applicable stockholder rights agreement so that Holders
would not be entitled to receive any rights in respect of Common Stock, if any, that the Company is
required to deliver upon conversion of Securities, the Conversion Rate will be adjusted at the time
of separation as if the Company had distributed to all holders of Common Stock capital stock,
evidences of indebtedness or other assets or property pursuant to Section 4.06(c) above, subject to
readjustment upon the subsequent expiration, termination or redemption of the rights. Other than
as specified above in this clause 4.06(h), there will not be any adjustment to the Conversion Rate
as the result of issuance of any such rights, the distribution of separate certificates
representing such rights, the exercise or redemption of such rights in accordance with any rights
plan or the termination or invalidation of any such rights.

     (i) For purposes of this Section 4.06, 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.

     Section 4.07. No Adjustment.

     (a) The Company shall not be required to make any adjustment to the Conversion Rate in
accordance with the provisions of Section 4.06 if Holders of the Securities are permitted to
participate, on an as-converted basis, in the transactions described in Section 4.06 (assuming for
this purpose that each $1,000 principal amount of Securities were convertible solely into a number
of shares of Common Stock equal to the Conversion Rate).

     (b) No adjustment in the Conversion Rate shall be required to be made unless the adjustment
would require an increase or decrease of at least 1% of the Conversion Rate. If the adjustment is
not made because the adjustment does not change the Conversion Rate by at least

 

 

1%, then the adjustment that is not made will be carried forward and taken into account in any
future adjustment. All required calculations will be made to the nearest cent or 1/10,000th of a
share, as the case may be. Notwithstanding the foregoing, all adjustments not previously made
shall have effect with respect to any conversion of Securities in connection with a Fundamental
Change and any conversion on or after June 15, 2012.

     (c) Notwithstanding anything to the contrary contained herein, in addition to the other events
set forth herein on account of which no adjustment to the Conversion Rate shall be made, the
applicable Conversion Rate shall not be adjusted for: (i) the issuance of any Common Stock
pursuant to any present or future plan providing for the reinvestment of dividends or interest
payable on securities of the Company and the investment of additional optional amounts in Common
Stock under any plan; (ii) the issuance of any shares of Common Stock or options or rights to
purchase those shares pursuant to any present or future employee, director or consultant benefit
plan, employee agreement or arrangement or program of the Company; (iii) the issuance of any shares
of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible
security outstanding as of the date the Securities were first issued; (iv) a change in the par
value of the Common Stock; (v) accumulated and unpaid dividends or distributions; and (vi) as a
result of a tender offer solely to holders of fewer than 100 shares of Common Stock.

     (d) Notwithstanding anything in this Section 4.06 to the contrary, in no event shall the
Conversion Rate be adjusted so that the Conversion Price would be less than $0.01.

     Section 4.08. Notice of Adjustment.

     Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file
with the Trustee and any Conversion Agent other than the Trustee, an Officer’s Certificate setting
forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have received
such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of
the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still
in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which
each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion
Rate to Holders within 20 Business Days after the effective date of such adjustment. Failure to
deliver such notice shall not affect the legality or validity of any such adjustment.

     Section 4.09. Notice of Certain Transactions.

     In the event there is a dissolution or liquidation of the Company, the Company shall mail to
Holders and file with the Trustee a notice stating the effective date. The Company shall mail such
notice at least 20 days before such proposed effective date. Failure to mail such notice or any
defect therein shall not affect the validity of any transaction referred to in this Section 4.09.

 

 

     Section 4.10. Effect of Reclassification, Consolidation, Merger or Sale on Conversion
Privilege.

     (a) If any of the following events occur (each, a “Business Combination”), namely:

     (1) any recapitalization, reclassification or change of the Common Stock, other than
(A) a change in par value, or from par value to no par value, or from no par value to par
value, or (B) as a result of a subdivision or combination,

     (2) a consolidation, merger or combination of the Company with another Person, or

     (3) a sale, lease or other transfer to another Person of all or substantially all of
the consolidated assets of the Company and its Subsidiaries. For purposes of the foregoing,
the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all the assets of one or more of the Company’s
Subsidiaries, the capital stock of which constitute all or substantially all the assets of
the Company to a Person other than the Company or any Subsidiary of the Company, shall be
deemed to be the transfer of all or substantially all the assets of the Company.

     (4) any statutory share exchange of the Company with another Person,

in each case as a result of which holders of Common Stock are entitled to receive stock, other
securities, other property or assets (including cash or any combination thereof) with respect to or
in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case
may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as
in force at the date of execution of such supplemental indenture if such supplemental indenture is
then required to so comply) providing that from and after the effective date of such Business
Combination, upon conversion of Securities, the settlement of the Conversion Value in accordance
with the provisions of Section 4.12 shall be based on, and each Remaining Share, if any,
deliverable in respect of any such settlement shall consist of, the kind and amount of shares of
stock, other securities or other property or assets (including cash or any combination thereof)
which holders of Common Stock are entitled to receive in respect of each share of Common Stock upon
such Business Combination. In the event holders of Common Stock have the opportunity to elect the
form of consideration to be received in such Business Combination, the Company shall make adequate
provision whereby the Holders of the Securities shall have a reasonable opportunity to determine
the form of consideration into which all of the Securities, treated as a single class, shall be
convertible from and after the effective date of such Business Combination. Such determination
shall be (i) based on the weighted average of elections made by Holders of the Securities who
participate in such determination, (ii) subject to any limitations to which all of the holders of
the Common Stock are subject, such as pro rata reductions applicable to any portion of the
consideration payable in such Business Combination and (iii) conducted in such a manner as to be
completed by the date which is the earlier of (a) the deadline for elections to be made by
stockholders of the Company, and (b) two Scheduled Trading Days prior to the anticipated effective
date of the Business Combination. The Company shall provide notice of the opportunity to determine
the form of such consideration, as well as notice of the

 

 

determination made by Holders of the Securities (and the weighted average of elections), by issuing
a press release or providing other notice deemed appropriate by the Company, and by providing a
copy of such notice to the Trustee. In the event the effective date of the Business Combination is
delayed more than 10 days beyond the initially anticipated effective date, Holders of the
Securities shall be given the opportunity to make subsequent similar determinations in regard to
such delayed effective date. Such supplemental indenture shall provide for adjustments of the
Conversion Rate and other appropriate numerical thresholds which shall be as nearly equivalent as
may be practicable to the adjustments of the Conversion Rate provided for in this Article 4. If,
in the case of any such Business Combination, the stock or other securities and assets receivable
thereupon by a holder of shares 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 Business Combination, 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 repurchase rights
set forth in Article 3 hereof. The Company shall not become a party to any Business Combination
unless its terms are materially consistent with the provisions of this Section 4.10. The above
provisions of this Section 4.10 shall similarly apply to successive Business Combinations. None of
the provisions of this Section 4.10 shall affect the right of a Holder of Securities to convert its
Securities in accordance with the provisions of this Article 4 prior to the effective date of a
Business Combination.

     If this Section 4.10(a) applies to any event or occurrence, Section 4.06 hereof shall not
apply.

     (b) In the event the Company shall execute a supplemental indenture pursuant to this Section
4.10, the Company shall promptly file with the Trustee (1) an Officer’s Certificate briefly stating
the reasons therefore and that all conditions precedent have been complied with and (2) an Opinion
of Counsel to the effect that all conditions precedent thereto and hereunder have been complied
with and that the execution and delivery of the Supplemental Indenture is authorized or permitted
under the Indenture, and shall promptly mail notice of the execution of such supplemental indenture
to all Holders. Failure to mail such notice or any defect therein shall not affect the validity of
such transaction and such supplemental indenture.

     Section 4.11. Trustee’s Disclaimer.

     (a) The Trustee shall have no duty to determine when an adjustment under this Article 4 should
be made, how it should be made or what such adjustment should be, but may accept as conclusive
evidence of that fact or the correctness of any such adjustment, and shall be protected in relying
upon, an Officer’s Certificate and Opinion of Counsel, including the Officer’s Certificate with
respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08.
The Trustee makes no representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure
to comply with any provisions of this Article 4, including, without limitation, whether or not a
Supplemental Indenture is required to be executed.

 

 

     (b) The Trustee shall not be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may
accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying
upon, the Officer’s Certificate and Opinion of Counsel, with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 4.10.

     Section 4.12. Settlement Upon Conversion.

     (a) Holders surrendering Securities for conversion shall be entitled to receive, for each
$1,000 principal amount of Securities surrendered for conversion: (A) cash in an amount equal to
the lesser of (1) $1,000 and (2) the Conversion Value; and (B) if the Conversion Value is greater
than $1,000, a number of shares of Common Stock (the “Remaining Shares”) equal to the sum of the
Daily Share Amounts for each of the 40 consecutive Trading Days in the Conversion Reference Period,
appropriately adjusted to reflect events occurring during the Conversion Reference Period that
would result in an adjustment to the Conversion Rate in accordance with the provisions of Section
4.06, subject to the Company’s right to deliver cash in lieu of all or a portion of such Remaining
Shares as set forth in Section 4.12(b). The Company will deliver such cash and any shares of
Common Stock, together with any cash payable for fractional shares, to such Holder in accordance
with Section 4.02(a).

     (b) The Company may elect to pay cash to the Holders of Securities surrendered for conversion
in lieu of all or a portion of the Remaining Shares otherwise issuable pursuant to Section 4.12(a).
In such event, on any day prior to the first Trading Day of the applicable Conversion Reference
Period, the Company may specify a percentage of the Daily Share Amount that will be settled in cash
(the “Cash Percentage”). If the Company elects to specify a Cash Percentage, the amount of cash
that the Company will deliver in respect of the Daily Share Amount for each Trading Day in the
applicable Conversion Reference Period will equal the product of: (1) the Cash Percentage, (2) the
Daily Share Amount for such Trading Day and (3) the Volume Weighted Average Price of the Company’s
Common Stock on such Trading Day. The number of shares that the Company shall deliver in respect
of the Daily Share Amount for each Trading Day in the applicable Conversion Reference Period will
be a percentage of the Daily Share Amount equal to 100% minus the Cash Percentage. If the Company
does not specify a Cash Percentage by the start of the applicable Conversion Reference Period, the
Company shall settle 100% of the Daily Share Amount for each Trading Day in the applicable
Conversion Reference Period with shares of Common Stock; provided, however, that the Company shall
pay cash in lieu of fractional shares otherwise issuable upon conversion of the Securities in
accordance with Section 4.03.

     (c) For the purposes of Sections 4.12(a) and (b), in the event that any of Conversion Value,
Daily Conversion Value, Daily Share Amounts, or Volume Weighted Average Price is not calculable for
all portions of the Conversion Reference Period, the Company’s Board of Directors shall in good
faith determine the values necessary to calculate the Conversion Value, Daily Conversion Value,
Daily Share Amounts, and Volume Weighted Average Price (which calculations shall be evidenced by an
Officer’s Certificate delivered to the Trustee).

 

 

     Section 4.13. Certain Conversions.

     Notwithstanding anything to the contrary in this Article 4, in the event of a Fundamental
Change in which the consideration is comprised entirely of cash, the Conversion Value will be
calculated based solely on the amount of cash which holders of the Company’s Common Stock are
entitled to receive in respect of each share of Common Stock upon such Fundamental Change. In such
event, the Company will pay the Holders in cash, as promptly as practicable but in any event not
later than the third Trading Day following the surrender of the Securities for conversion.

ARTICLE 5

COVENANTS

     Section 5.01. Payment of Securities.

     (a) The Company shall promptly make all payments in respect of the Securities on the dates and
in the manner provided in the Securities and this Indenture. A payment of principal or interest
shall be considered paid on the date it is due if the Paying Agent (other than the Company) (or if
the Company is the Paying Agent, the segregated account or separate trust fund maintained by the
Company pursuant to Section 2.04) holds by 10:00 a.m., New York City time, on that date money,
deposited by or on behalf of the Company sufficient to make the payment. Accrued and unpaid
interest on any Security that is payable (whether or not punctually paid or duly provided for) on
any Interest Payment Date shall be paid to the Person in whose name that Security is registered at
the close of business on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose. The Company shall, to the fullest extent permitted by law,
pay interest in immediately available funds on overdue principal and interest at the annual rate
borne by the Securities compounded semiannually, which interest shall accrue from the date such
overdue amount was originally due to the day preceding the date payment of such amount, including
interest thereon, has been made or duly provided for. All such interest shall be payable on
demand.

     (b) Payment of the principal of and interest, if any, on the Securities shall be made at the
office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City
of New York (which shall initially be the Corporate Trust Office of the Trustee) in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company payment of interest
on any Certificated Securities having an aggregate principal amount of $5,000,000 or less may be
made by check mailed to the address of the Person entitled thereto as such address appears in the
Register; provided further that a Holder of a Certificated Security having an aggregate principal
amount of more than $5,000,000 will be paid by wire transfer in immediately available funds at the
election of such Holder if such Holder has provided wire transfer instructions to the Trustee at
least 10 Business Days prior to the payment date. Any wire transfer instructions received by the
Trustee will remain in effect until revoked by the Holder. In the case of a permanent Global
Security, interest payable on any applicable payment date will be paid to the Depositary, with
respect to that portion of such permanent Global Security held for its

 

 

account by Cede & Co. for the purpose of permitting such party to credit the interest
received by it in respect of such permanent Global Security to the accounts of the beneficial
owners thereof.

     Section 5.02. Reports by Company.

     (a) The Company shall file with the Trustee, within 15 days after it is required to file them
with the SEC, copies of all annual reports, quarterly reports and other documents that the Company
files with the SEC pursuant to Section 13 or 15(d) of the Exchange Act; provided that any such
reports and documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and
Retrieval system (or EDGAR) shall be deemed to be filed with the Trustee. The Company also shall
comply with the provisions of TIA Section 314(a).

     (b) Delivery of such reports and documents to the Trustee is for informational purposes only
and the Trustee’s receipt of such 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 rely
exclusively on Officer’s Certificates). The Trustee may assume that any reports required to be
filed under subsection (a) above have been filed with the SEC and shall have no obligation to
verify any such filing.

     Section 5.03. Compliance Certificates.

     The Company shall deliver to the Trustee, within one hundred twenty (120) days after the end
of each fiscal year of the Company (beginning with the fiscal year ending May 31, 2008), an
Officer’s Certificate as to the signer’s knowledge of the Company’s compliance with all conditions
and covenants on its part contained in this Indenture and stating whether or not the signer knows
of any Default or Event of Default. If such signer knows of such a Default or Event of Default,
the Officer’s Certificate shall describe the Default or Event of Default and the efforts to remedy
the same. For the purposes of this Section 5.03, compliance shall be determined without regard to
any grace period or requirement of notice provided pursuant to the terms of this Indenture.

     Section 5.04. Further Instruments and Acts.

     Upon request of the Trustee, the Company will execute and deliver such further instruments and
do such further acts as may be reasonably necessary or proper to carry out more effectively the
purposes of this Indenture.

     Section 5.05. Maintenance of Corporate Existence.

     Subject to Article 6, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence.

     Section 5.06. Rule 144A Information Requirement.

     During the period prior to the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision), 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, upon the request of any Holder or beneficial holder of the Securities, make
available to such Holder or beneficial holder of Securities or any Common Stock issued upon
conversion thereof which continue to be Restricted Securities in connection with any sale thereof
and any prospective purchaser of Securities or such Common Stock designated by such Holder or
beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act
and it will take such further action as any Holder or beneficial holder of such Securities or such
Common Stock may reasonably request, all to the extent required from time to time 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, as such Rule may be
amended from time to time. Whether a person is a beneficial holder shall be determined by the
Company.

     Section 5.07. Stay, Extension And Usury Laws.

     The Company covenants (to the extent that they may lawfully do so) that it shall not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law or other law which would prohibit or forgive the Company from paying
all or any portion of the principal of or accrued but unpaid interest on the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect
the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will
not, by resort to any such law, hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as though no such law
had been enacted.

     Section 5.08. Payment of Additional Interest.

     If Additional Interest is payable by the Company pursuant to the Registration Rights
Agreement, the Company shall promptly deliver to the Trustee an Officer’s Certificate to that
effect stating (i) the amount of such Additional Interest that is payable, (ii) the reason why such
Additional Interest is payable and (iii) the date on which such Additional Interest is payable.
Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume
without inquiry that no such Additional Interest is payable. If the Company has paid Additional
Interest directly to the Persons entitled to such Additional Interest, the Company shall deliver to
the Trustee a certificate setting forth the particulars of such payment.

     Section 5.09. Maintenance of Office or Agency.

     The Company shall maintain an office or agency where Securities may be presented or
surrendered for payment. The Company also will maintain an office or agency where Securities may
be surrendered for registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities and this Indenture may be served. The office of the
Trustee, at its Corporate Trust Office, will be such office or agency of the Company, unless the
Company shall designate and maintain some other office or agency for one or more of such purposes.
The Company will give prompt written notice to the Trustee of the location and any change in the
location of any such offices or agencies. If at any time the Company shall fail to maintain any
such required offices or agencies or shall fail to furnish the Trustee with the address

 

 

thereof, such presentations, surrenders, notices and demands may be made or served at the
office of the Trustee and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Company may from time to time designate one or more other offices or agencies (in or
outside of The City of New York) where the Securities may be presented or surrendered for any or
all such purposes, and may from time to time rescind such designation. The Company will give
prompt written notice to the Trustee of any such designation or rescission and any change in the
location of any such office or agency.

such other Indebtedness has not been repaid within a period

 

 

of 30 days after receipt by the Company of a Notice of Default specifying the default,

Default by reason thereof would not be deemed to have occurred; or

in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding
under any applicable Bankruptcy Law or (y) a decree or order adjudging the Company or any

effect for a period of 90 consecutive days; or

     (8) (i) the Company or any Significant Subsidiary commences a voluntary case or
proceeding under any applicable Bankruptcy Law or any other case or proceeding to be

     (ii) the Company or any Significant Subsidiary consents to the entry of a decree

     (b) Notwithstanding Section 7.01(a) no Event of Default under clauses (5) or (6) of Section
7.01(a) shall occur until the Trustee notifies the Company in writing, or the Holders of at least
25% in aggregate principal amount of the Securities then Outstanding notify the Company

 

 

and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not
cure the Default within the time specified in clauses (5) or (6), respectively, of Section 7.01(a),
or obtain a waiver, after receipt of such notice. A notice given pursuant to this Section 7.01
shall be given by registered or certified mail, must specify the Default, demand that it be
remedied and state that the notice is a Notice of Default. When any Default under this Section
7.01 is cured, it ceases.

     (c) The Company will deliver to the Trustee, within 30 days after becoming aware of the
occurrence of a Default or Event of Default, written notice thereof.

     Section 7.02. Acceleration.

     If an Event of Default (other than an Event of Default specified in clause (7) or (8) of
Section 7.01(a)) shall occur and be continuing with respect to this Indenture, the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Securities then Outstanding may,
and the Trustee at the request of such Holders shall, declare all unpaid principal of and accrued
and unpaid interest through the date of such declaration on all Securities to be immediately due
and payable, by a notice in writing to the Company (and to the Trustee if given by the Holders of
the Securities). Upon any such declaration, such principal and interest shall become due and
payable immediately. If an Event of Default specified in clause (7) or (8) of Section 7.01(a)
occurs and is continuing, then all the Securities shall ipso facto become and be due and payable
immediately in an amount equal to the principal amount of the Securities, together with accrued and
unpaid interest, if any, to the date the Securities become due and payable, without any declaration
or other act on the part of the Trustee or any Holder. Thereupon, the Trustee may, at its
discretion, proceed to protect and enforce the rights of the Holders of the Securities by
appropriate judicial proceedings.

     After a declaration of acceleration with respect to the Securities, but before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in aggregate principal amount of the Securities Outstanding, by
written notice to the Company and the Trustee, may rescind and annul such declaration and its
consequences if:

     (a) the Company has paid or deposited with the Trustee a sum sufficient to pay

     (1) all sums paid or advanced by the Trustee under this Indenture and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,

     (2) all overdue interest on all Outstanding Securities,

     (3) the principal of any Outstanding Securities which have become due otherwise than by
such declaration of acceleration and interest thereon at the rate borne by the Securities,
and

     (4) to the extent that payment of such interest is lawful, interest upon overdue
interest at the rate borne by the Securities;

 

 

     (b) the rescission would not conflict with any judgment or decree of a court of competent
jurisdiction; and

     (c) all Events of Default, other than the non-payment of principal of and interest on the
Securities which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 7.13. No such rescission shall affect any subsequent Default or
impair any right consequent thereon.

     Notwithstanding the foregoing, to the extent elected by the Company, the sole remedy for an
Event of Default relating to the failure by the Company to comply with the provisions of Section
5.02 of this Indenture shall, for the first 60 days after the occurrence of such an Event of
Default, consist exclusively of the right to receive special interest (“Special Interest”) on the
Securities at an annual rate equal to 0.25% of the principal amount of the Securities. Such
Special Interest shall be paid semi-annually in arrears, with the first semi-annual payment due on
the first Interest Payment Date following the date on which such Special Interest began to accrue
on the Securities. Special Interest shall accrue on all Outstanding Securities from and including
the date on which an Event of Default relating to a failure to comply with the provisions of
Section 5.02 shall first occur to but not including the 60th day thereafter (or such earlier date
on which such Event of Default shall have been cured or waived). On such 60th day (or earlier, if
the Event of Default relating to the failure to comply with Section 5.02 is cured or waived prior
to such 60th day), such Special Interest shall cease to accrue and, if the Event of Default
relating to the failure to comply with Section 5.02 shall not have been cured or waived prior to
such 60th day, the Securities shall be subject to acceleration as provided in this Section 7.02.
The provisions of this paragraph shall not affect the rights of holders in the event of the
occurrence of any other Event of Default. In the event the Company shall not elect to pay Special
Interest upon an Event of Default resulting from the failure of the Company to comply with the
provisions of Section 5.02, the Securities shall be subject to acceleration as provided above in
this Section 7.02.

     If the Company shall elect to pay Special Interest in connection with an Event of Default
relating to its failure to comply with the requirements of Section 5.02, (1) the Company shall
notify all Holders and the Trustee and Paying Agent of such election on or before the close of
business on the date on which such Event of Default shall first occur, and (2) all references
herein to interest accrued or payable as of any date shall include any Special Interest accrued or
payable as of such date as provided in this Section 7.02.

     Section 7.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

     (a) default is made in the payment of any interest on any Security when such interest becomes
due and payable and such default continues for a period of 30 days, or

     (b) default is made in the payment of the principal of any Security at the Stated Maturity
thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and interest,

 

 

with interest upon the overdue principal and, to the extent that payment of such interest shall be
legally enforceable, upon overdue installments of interest, at the rate borne by the Securities;
and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of the property of the
Company or any other obligor upon the Securities, wherever situated.

     If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture by such
appropriate private or judicial proceedings as the Trustee shall deem most effectual to protect and
enforce such rights, whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper
remedy, subject however to Section 7.12. No recovery of any such judgment upon any property of the
Company shall affect or impair any rights, powers or remedies of the Trustee or the Holders.

     Section 7.04. Trustee May File Proofs of Claim.

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

     (a) to file and prove a claim for the whole amount of principal and interest owing and unpaid
in respect of the Securities and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of
the Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses,

 

 

disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.07.

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

     Section 7.05. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name and as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

     Section 7.06. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article 7 or otherwise on behalf of the
Holders or the Trustee pursuant to this Article 7 or through any proceeding or any arrangement or
restructuring in anticipation or in lieu of any proceeding contemplated by this Article 7 shall be
applied, subject to applicable law, in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal or interest, upon
presentation of the Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 8.07;

     SECOND: To the payment of the amounts then due and unpaid upon the Securities for principal
and interest, in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts due and payable on
such Securities for principal and interest; and

     THIRD: The balance, if any, to the Company, provided that all sums due and owing to the
Holders and the Trustee have been paid in full as required by this Indenture.

     Section 7.07. Limitation on Suits.

     No Holder of any Securities shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture or the Securities, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

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

 

 

     (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute proceedings in respect of
such Event of Default in its own name as trustee hereunder;

     (c) such Holder or Holders have offered to the Trustee an indemnity reasonably satisfactory to
it against the costs, expenses and liabilities to be incurred in compliance with such request;

     (d) the Trustee for 15 days after its receipt of such notice, request and offer (and if
requested, provision) of indemnity has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to the Trustee during
such 15-day period by the Holders of a majority in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any right in any manner
whatever by virtue of, or by availing of, any provision of this Indenture or any Security to
affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain
priority or preference over any other Holders or to enforce any right under this Indenture or any
Security, except in the manner provided in this Indenture and for the equal and ratable benefit of
all the Holders (it being understood that the Trustee does not have an affirmative duty to
ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

     Section 7.08. Unconditional Right of Holders to Receive Payment and to Convert.

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Security
to receive payment of the principal amount, interest, Fundamental Change Purchase Price, if any,
Additional Interest, if any, or Special Interest, if any, in respect of the Securities held by such
Holder, on or after the respective due dates expressed in the Securities and this Indenture
(whether upon repurchase or otherwise), and to convert such Security in accordance with Article 4,
and to bring suit for the enforcement of any such payment on or after such respective due dates or
for the right to convert in accordance with Article 4, is absolute and unconditional and shall not
be impaired or affected without the consent of the Holder.

     Section 7.09. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case the
Company, any other obligor on the Securities, the Trustee and the Holders shall, subject to any
determination in such proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as
though no such proceeding had been instituted.

     Section 7.10. Rights and Remedies Cumulative.

     No right or remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and remedy shall, to the

 

 

extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     Section 7.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article 7 or by law to the Trustee or to the Holders may be exercised from time to time, and
as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

     Section 7.12. Control by Holders.

     The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, provided that:

     (a) such direction shall not be in conflict with any rule of law or with this Indenture,
expose the Trustee to personal liability, or be unduly prejudicial to Holders not joining therein;
and

     (b) subject to the provisions of Section 315 of the TIA, the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction.

     Section 7.13. Waiver of Past Defaults.

     Subject to Sections 7.08, the Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may waive an existing Default or Event of
Default and its consequences, except an uncured Default or Event of Default in the payment of the
principal of or any accrued but unpaid interest on any Security, an uncured failure by the Company
to convert any Securities into Common Stock and cash, as applicable, or any Default or Event of
Default in respect of any provision of this Indenture or the Securities which, under Section 10.02,
cannot be modified or amended without the consent of the Holder of each Security affected. When a
Default or Event of Default is waived, it is cured and ceases to exist.

     Section 7.14. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or defenses

 

 

made by such party litigant, but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of or interest on, any
Security on or after the respective Stated Maturities expressed in such Security (or, in the case
of purchase pursuant to Article 3 hereof, on the Fundamental Change Purchase Date).

     Section 7.15. Remedies Subject to Applicable Law.

     All rights, remedies and powers provided by this Article 7 may be exercised only to the extent
that the exercise thereof does not violate any applicable provision of law in the premises, and all
the provisions of this Indenture are intended to be subject to all applicable mandatory provisions
of law which may be controlling in the premises and to be limited to the extent necessary so that
they will not render this Indenture invalid, unenforceable or not entitled to be recorded,
registered or filed under the provisions of any applicable law.

ARTICLE 8

TRUSTEE

     Section 8.01. Duties of Trustee.

     Subject to the provisions of TIA Sections 315(a) through 315(d):

     (a) if a Default or an Event of Default has occurred and is continuing, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture and use the same degree of
care and skill in its exercise thereof as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs;

     (b) except during the continuance of a Default or an Event of Default:

     (1) the Trustee need perform only those duties as are specifically set forth in this
Indenture and no covenants or obligations shall be implied in this Indenture that are
adverse to the Trustee; and

     (2) in the absence of bad faith or willful misconduct 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, in the case of certificates or opinions
specifically required by any provision hereof to be furnished to it, 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:

     (1) this clause (c) does not limit the effect of clause (b) of this Section 8.01;

 

 

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

take in good faith, in accordance with a direction of the Holders of a majority in principal
amount of Outstanding Securities relating to the time, method and place of conducting any

conferred upon the Trustee under this Indenture;

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

     (e) whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to clauses (a), (b), (c) and (d) and (f) of this Section
8.01; and

     (f) the Trustee shall not be liable for interest on any money or assets received by it except
as the Trustee may agree with the Company. Assets held in trust by the Trustee need not be
segregated from other assets except to the extent required by law.

     Section 8.02. Notice of Default.

     Within 30 days after a Trust Officer of the Trustee receives written notice of the occurrence
of any Default, the Trustee shall transmit by mail to all Holders and any other Persons entitled to
receive reports pursuant to Section 313(c) of the TIA, as their names and addresses appear in the
Security Register, notice of such Default hereunder known to the Trustee, unless such Default shall
have been cured or waived; provided, however, that, except in the case of a Default in the payment
of the principal of or interest on any Security or the failure to deliver amounts owing upon
conversion of a Security in accordance with the provisions of Article 4, the Trustee shall be
protected in withholding such notice if and so long as a trust committee of Trust Officers of the
Trustee in good faith determines that the withholding of such notice is in the interest of the
Holders.

     Section 8.03. Certain Rights of Trustee.

     Subject to the provisions of Section 8.01 hereof and TIA Sections 315(a) through 315(d):

     (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining

facts or matters as it may deem fit, and, if the Trustee shall determine to make such further

Company, personally or by agent or attorney at the sole cost of the Company and shall incur no
additional liability of any kind by reason of such inquiry or investigation;

     (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties

     (j) the permissive rights of the Trustee enumerated herein shall not be construed as duties of
the Trustee.

 

 

     Section 8.04. Trustee Not Responsible for Recitals, Dispositions of Securities or
Application of Proceeds Thereof.

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its
obligations hereunder and that the statements made by it in any Statement of Eligibility and
Qualification on Form T-1 to be supplied to the Company will be true and accurate subject to the
qualifications set forth therein. The Trustee shall not be accountable for the use or application
by the Company of Securities or the proceeds thereof.

     Section 8.05. Trustee and Agents May Hold Securities; Collections; etc.

     The Trustee, any Paying Agent, Security Registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities, with the same
rights it would have if it were not the Trustee, Paying Agent, Security Registrar or such other
agent and, subject to TIA Sections 310 and 311, may otherwise deal with the Company and receive,
collect, hold and retain collections from the Company with the same rights it would have if it were
not the Trustee, Paying Agent, Security Registrar or such other agent.

     Section 8.06. Money Held in Trust.

     All moneys received by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received, but need not be segregated from other funds
except to the extent required by mandatory provisions of law.

     Section 8.07. Compensation and Indemnification of Trustee and Its Prior Claim.

     The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as the parties shall agree in writing from time to time for
all services rendered by it hereunder (which compensation shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) and the Company covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf of the Trustee in
accordance with any of the provisions of this Indenture (including the reasonable compensation and
the expenses and disbursements of its counsel and of all agents and other persons not regularly in
its employ) except any such expense, disbursement or advance as shall be determined to have been
caused by its own negligence, bad faith or willful misconduct. The Company also covenants and
agrees to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless against,
any claim, loss, liability, damage, tax, assessment or other governmental charge (other than taxes
applicable to the Trustee’s compensation hereunder) or expense incurred without negligence, bad
faith or willful misconduct on its part, arising out of or in connection with the acceptance or
administration of this Indenture or the trusts hereunder and its duties hereunder, including
enforcement of this Section 8.07 and also including any liability which the Trustee may incur as a
result of failure to withhold, pay or report any tax, assessment

 

 

or other governmental charge, and the costs and expenses of defending itself against or
investigating any claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder. The obligations of the Company under this Section 8.07 to compensate
and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each
predecessor Trustee for reasonable expenses, disbursements and advances shall constitute an
additional obligation hereunder and shall survive the satisfaction and discharge of this Indenture
and the resignation or removal of the Trustee and each predecessor Trustee. To secure the
Company’s payment obligations in this Section 8.07, the Trustee shall have a prior claim to Holders
of Securities on all money or property held or collected by the Trustee other than money or
property held in trust for the benefit of the Holders of particular Securities.

     Section 8.08. Conflicting Interests.

     The Trustee shall comply with the provisions of Section 310(b) of the TIA.

     Section 8.09. Trustee Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to act as trustee
under TIA Section 310(a) and which shall have a combined capital and surplus of at least
$100,000,000, to the extent there is an institution eligible and willing to serve. If the Trustee
does not have a Corporate Trust Office in The City of New York, the Trustee may appoint an agent in
The City of New York reasonably acceptable to the Company to conduct any activities which the
Trustee may be required under this Indenture to conduct in The City of New York. If such Trustee
publishes reports of condition at least annually, pursuant to law or to the requirements of
federal, state, territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section 8.09, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.09, the Trustee shall resign immediately in the manner and with the
effect hereinafter specified in this Article 8.

     Section 8.10. Resignation and Removal; Appointment of Successor Trustee.

     (a) No resignation or removal of the Trustee and no appointment of a successor trustee
pursuant to this Article 8 shall become effective until the acceptance of appointment by the
successor trustee under Section 8.11.

     (b) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by
giving written notice thereof to the Company no later than 20 Business Days prior to the proposed
date of resignation. Upon receiving such notice of resignation, the Company shall promptly appoint
a successor trustee by written instrument executed by authority of the Board of Directors of the
Company, a copy of which shall be delivered to the resigning Trustee and a copy to the successor
trustee. If an instrument of acceptance by a successor trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee
may, at the expense of the Company, or any Holder who has been a bona fide Holder of a Security for
at least six months may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor trustee.

 

 

Such court may thereupon, after such notice, if any, as it may deem proper, appoint and prescribe a
successor trustee.

     (c) The Trustee may be removed at any time for any cause or for no cause by an Act of the
Holders of not less than a majority in aggregate principal amount of the Outstanding Securities,
delivered to the Trustee and to the Company.

     (d) If at any time:

     (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after
written request therefor by the Company or by any Holder who has been a bona fide Holder of
a Security for at least six months,

     (2) the Trustee shall cease to be eligible under Section 8.09 and shall fail to resign
after written request therefor by the Company or by any Holder who has been a bona fide
Holder of a Security for at least six months, or

     (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then, in any case, (i) the Company
by a Board Resolution may remove the Trustee, or (ii) subject to Section 7.14, the Holder of
any Security who has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

     (e) If the Trustee shall be removed or become incapable of acting, or if a vacancy shall occur
in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint
a successor trustee and shall comply with the applicable requirements of Section 8.11. If, within
60 days after such removal or incapability, or the occurrence of such vacancy, the Company has not
appointed a successor Trustee, a successor trustee shall be appointed by the Act of the Holders of
a majority in principal amount of the Outstanding Securities delivered to the Company and the
retiring Trustee. Such successor trustee so appointed shall forthwith upon its acceptance of such
appointment become the successor trustee. If no successor trustee shall have been so appointed by
the Company or the Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Trustee or the Holder of any Security who has been a bona fide Holder for at least
six months may, subject to Section 7.14, on behalf of himself and all others similarly situated,
petition at the expense of the Company any court of competent jurisdiction for the appointment of a
successor trustee.

     (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor trustee by mailing written notice of such event by first-class mail,
postage prepaid, to the Holders of Securities as their names and addresses appear in the register
of the Registrar. Each notice shall include the name of the successor trustee and the address of
its Corporate Trust Office or agent hereunder.

 

 

     Section 8.11. Acceptance of Appointment by Successor.

     (a) Every successor trustee appointed hereunder shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee as if originally named as Trustee hereunder; but,
nevertheless, on the written request of the Company or the successor trustee, upon payment of its
charges pursuant to Section 8.07 then unpaid, such retiring Trustee shall pay over to the successor
trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument
transferring to such successor trustee all such rights, powers, duties and obligations. Upon
request of any such successor trustee, the Company shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor trustee all such rights and powers.

     (b) No successor trustee with respect to the Securities shall accept appointment as provided
in this Section 8.11 unless at the time of such acceptance such successor trustee shall be eligible
to act as trustee under the provisions of TIA Section 310(a) and this Article 8 and shall have a
combined capital and surplus of at least $100,000,000 and have a Corporate Trust Office or an agent
selected in accordance with Section 8.09.

     (c) Upon acceptance of appointment by any successor trustee as provided in this Section 8.11,
the Company shall give notice thereof to the Holders of the Securities, by mailing such notice to
such Holders at their addresses as they shall appear on the Security Register. If the acceptance
of appointment is substantially contemporaneous with the appointment, then the notice called for by
the preceding sentence may be combined with the notice called for by Section 8.10. If the Company
fails to give such notice within 10 days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be given at the expense of the Company.

     Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee (including the trust created by this Indenture) shall be
the successor of the Trustee hereunder, provided that such corporation shall be eligible under TIA
Section 310(a) and this Article 8 and shall have a combined capital and surplus of at least
$100,000,000 and have a Corporate Trust Office or an agent selected in accordance with Section
8.09, without the execution or filing of any paper or any further act on the part of any of the
parties hereto.

     In case at the time such successor 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 trustee; and in all
such cases such certificate 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; provided that the right to
adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in
the name of any predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

     Section 8.13. Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or other obligor under
the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection
of claims against the Company (or any such other obligor). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

     Section 8.14. Reports By Trustee.

     (a) Within 60 days after January 15 of each year commencing with the first January 15 after
the issuance of Securities, the Trustee, if so required under the TIA, shall transmit by mail to
all Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated
as of such January 15 in accordance with and with respect to the matters required by TIA Section
313(a). The Trustee shall also transmit by mail to all Holders, in the manner and to the extent
provided in TIA Section 313(c), a brief report in accordance with and with respect to the matters
required by TIA Section 313(b)(2).

     (b) A copy of each report transmitted to Holders pursuant to this Section 8.14 shall, at the
time of such transmission, be mailed to the Company and filed with each national securities
exchange, if any, upon which the Securities are listed and also with the SEC. The Company will
notify the Trustee promptly if the Securities are listed on any national securities exchange.

ARTICLE 9

for and except as further provided below), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this
Indenture, when either:

     (1) all Securities theretofore authenticated and delivered (other than (i) Securities
which have been destroyed, lost or stolen and which have been replaced or paid as provided
in Section 2.08 and (ii) Securities for whose payment money has theretofore been deposited
in trust and thereafter repaid to the Company as provided in Section 2.04) have been
delivered to the Trustee for cancellation; or

 

 

     (2) all such Securities not theretofore delivered to the Trustee for cancellation have
become due and payable, whether on the Final Maturity Date or a Fundamental Change Purchase
Date, upon conversion or otherwise,

provided, that

     (i) the Company has deposited with the Trustee, a Paying Agent (other than the Company
or any of its Affiliates) or a Conversion Agent, if applicable, immediately available funds
or immediately available funds and shares of Common Stock, in trust for the purpose of and
in an amount sufficient to pay and discharge all indebtedness and obligations related to
such Securities not theretofore delivered to the Trustee for cancellation, for principal and
interest (including Additional Interest, if any) to the date of such deposit or for the
payment of amounts due upon conversion;

     (ii) the Company has paid or caused to be paid all other sums payable hereunder by the
Company; and

     (iii) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion
of Counsel, each stating that all conditions precedent herein relating to the satisfaction

Company with respect to the Trustee under Section 8.07 and, if money shall have been deposited with
the Trustee pursuant to clause (2) of Section 9.01(a), the provisions of Sections 2.03, 2.04, 2.05,

until the Securities have been paid in full.

     Section 9.02. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 2.04, all United States dollars
deposited with the Trustee pursuant to Section 9.01 shall be held in trust and applied by it, in
accordance with the provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal of and interest on, the
Securities for whose payment such United States dollars have been deposited with the Trustee.

     Section 9.03. Reinstatement.

     If the Trustee, any Paying Agent or any Conversion Agent is unable to apply any money in
accordance with Section 9.02 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, then the Company’s obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time
as the Trustee, such Paying Agent or such Conversion Agent is permitted to apply all such money in
accordance with Section 9.02; provided, however, that if the Company has made any payment of the
principal of or interest on any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to

 

 

receive any such payment from the money held by the Trustee, such Paying Agent or such
Conversion Agent.

     If any provision hereof limits, qualifies or conflicts with any provision of the TIA or
another provision which is required or deemed to be included in this Indenture by any of the
provisions of the TIA, the provision or requirement of the TIA shall control. If any provision of
this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded,
as the case may be.

     Section 11.02. Notices.

     Any demand, authorization notice, request, consent or communication shall be given in writing
and mailed by first-class mail, postage prepaid, or delivered by recognized overnight courier

or at any other address previously furnished in writing to the Holders

or the Company or any other obligor on the Securities by the Trustee.

Such notices or communications shall be effective when received.

     The Company or the Trustee by notice to the other may designate additional or different
addresses for subsequent notices or communications.

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, or delivered by recognized overnight courier, to each Holder affected
by such event, at its address as it appears in the register kept by the Primary Registrar, not
later than the latest date, and not earlier than the earliest date, prescribed for the giving of
such notice or by any other manner deemed acceptable to the Trustee. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other
Holders. Any notice when mailed to a Holder in the aforesaid manner shall be conclusively deemed
to have been received by such Holder whether or not actually received by such Holder. Where this
Indenture provides for notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in reliance upon such
waiver.

     In case by reason of the suspension of regular mail service or by reason of any other cause,
it shall be impracticable to mail notice of any event as required by any provision of this
Indenture, then any method of giving such notice as shall be reasonably satisfactory to the Trustee
shall be deemed to be a sufficient giving of such notice.

     If the Company mails any notice to a Holder of a Security, it shall mail a copy to the Trustee
and each Registrar, Paying Agent and Conversion Agent.

     Section 11.03. Disclosure of Names and Addresses of Holders.

     Holders may communicate pursuant to TIA Section 312(b) with other Holders with respect to
their rights under this Indenture or the Securities, and the Trustee shall comply with TIA Section
312(b). The Company, the Trustee, the Registrar and any other Person shall have the protection of
TIA 312(c). Further, every Holder of Securities, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee or any agent of either of them
shall be held accountable by reason of the disclosure of any information as to the names and
addresses of the Holders in accordance with TIA Section 312, regardless of the source from which
such information was derived, and that the Trustee shall not be held accountable by reason of
mailing any material pursuant to a request made under TIA Section 312.

 

 

     Section 11.04. Compliance Certificates and Opinions.

     (a) Upon any application or request by the Company to the Trustee to take any action under any
provision of this Indenture and as may be requested by the Trustee, the Company and any other
obligor on the Securities (if applicable) shall furnish to the Trustee an Officer’s Certificate in
a form and substance reasonably acceptable to the Trustee stating that all conditions precedent, if
any, provided for in this Indenture (including any covenant compliance with which constitutes a
condition precedent) relating to the proposed action have been complied with, and an Opinion of
Counsel in a form and substance reasonably acceptable to the Trustee stating that in the opinion of
such counsel all such conditions precedent, if any, have been complied with, except that, in the
case of any such application or request as to which the furnishing of such certificates or opinions
is specifically required by any provision of this Indenture relating to such particular application
or request, no additional certificate or opinion need be furnished.

     (b) Every certificate or Opinion of Counsel with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

     (1) a statement that each individual signing such certificate or individual or firm
signing such opinion has read and understands such covenant or condition and the definitions
herein relating thereto;

     (2) a brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion are based;

     (3) a statement that, in the opinion of each such individual or such firm, he or it has
made such examination or investigation as is necessary to enable him or it to express an
informed opinion as to whether or not such covenant or condition has been complied with; and

     (4) a statement as to whether, in the opinion of each such individual or such firm,
such condition or covenant has been complied with.

     Section 11.05. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in
favor of the Trustee and the Company, if made in the manner provided in this Section 11.05.

 

 

     (b) The ownership of Securities shall be proved by the register maintained by the Primary
Registrar.

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

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

     (e) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to
a Board Resolution, fix in advance a record date for the determination of such Holders entitled to
give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), any such record
date shall be the record date specified in or pursuant to such Board Resolution, which shall be a
date not more than 30 days prior to the first solicitation of Holders generally in connection
therewith and no later than the date such first solicitation is completed.

     (f) If such a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be Holders for purposes of
determining whether Holders of the requisite proportion of Securities then Outstanding have
authorized or agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other Act, and for this purpose the Securities then Outstanding shall be
computed as of such record date; provided that no such request, demand, authorization, direction,
notice, consent, waiver or other Act by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than six
months after such record date.

     (g) For purposes of this Indenture, any action by the Holders which may be taken in writing
may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

     Section 11.06. Benefits of Indenture.

     Nothing in this Indenture or in the Securities, express or implied, shall give to any Person
(other than the parties hereto and their successors hereunder, any Paying Agent and the Holders)
any benefit or any legal or equitable right, remedy or claim under this Indenture.

 

 

     Section 11.07. Legal Holidays.

     In any case where any Interest Payment Date, Fundamental Change Purchase Date or Final
Maturity Date of any Security shall not be a Business Day, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of interest or principal need not be made
on such date, but may be made on the next succeeding Business Day with the same force and effect as
if made on such Interest Payment Date, Fundamental Change Purchase Date or Final Maturity Date, and
no interest shall accrue with respect to such payment for the period from and after such Interest
Payment Date, Fundamental Change Purchase Date or Final Maturity Date, as the case may be, to the
next succeeding Business Day.

     Section 11.08. Governing Law.

     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

     Section 11.09. No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt agreement of the
Company or a Subsidiary of the Company. Any such indenture, loan or debt agreement may not be used
to interpret this Indenture.

     Section 11.10. No Personal Liability of Directors, Officers, Employees and
Stockholders.

     No director, officer, employee, stockholder, incorporator or agent of the Company, as such,
will have any liability for any obligations of the Company under the Securities, the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
holder of the Securities by accepting a Security waives and releases all such liability.

     Section 11.11. Successors and Assigns.

     All covenants and agreements in this Indenture by the Company shall bind their respective
successors and assigns, whether so expressed or not.

     Section 11.12. Multiple Counterparts.

     The parties may sign multiple counterparts of this Indenture. Each signed counterpart shall
be deemed an original, but all of them together represent the same agreement.

     Section 11.13. Separability Clause.

     In case any provision in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

 

 

     Section 11.14. Schedules and Exhibits.

     All schedules and exhibits attached hereto are by this reference made a part hereof with the
same effect as if herein set forth in full.

     Section 11.15. Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 11.16. Waiver of Jury Trial.

     EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY.

     Section 11.17. Force Majeure.

     In no event shall the Trustee be responsible or liable for any failure or delay in the
performance of its obligations hereunder arising out of or caused by, directly or indirectly,
forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts
of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Trustee shall use reasonable efforts which are
consistent with accepted practices in the banking industry to resume performance as soon as
practicable under the circumstances.

[FORM OF REVERSE SIDE OF SECURITY]

Tektronix, Inc.

1.625% Senior Convertible Notes Due 2012

     1. Interest

     Tektronix, Inc., an Oregon corporation (the “Company”, which term shall include any successor
corporation under the Indenture hereinafter referred to), promises to pay interest on the principal
amount of this Note at the rate of 1.625% per annum. The Company shall pay interest semiannually
on January 15 and July 15 of each year (each an “Interest Payment Date”), commencing January 15,
2008. Interest payable on any Interest Payment Date shall include interest accrued from and
including the immediately preceding Interest Payment Date (or if none, from and including June 29,
2007) to but excluding the relevant Interest Payment Date. Cash interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. Any payment required to be made on a
day that is not a Business Day shall be made on the next succeeding Business Day with the same
force and effect as if made on such day and without any interest in respect of the delay. The
Company shall, to the fullest extent permitted by law, pay interest in immediately available funds
on overdue principal and interest at the rate of 1.625% per annum, compounded semiannually, which
interest shall accrue from the date such overdue amount was originally due to the day preceding the
date payment of such amount, including interest thereon, has been made or duly provided for.

     Any reference herein to interest accrued or payable as of any date shall include any
Additional Interest accrued or payable on such date as provided in the Registration Rights
Agreement and to any Special Interest that may be payable in accordance with the provisions of
Section 7.02 of the Indenture.

     2. Method of Payment

     The Company shall pay interest on this Note (except defaulted interest) to the person who is
the Holder of this Note at the close of business on January 1 or July 1, as the case may be (each,
a “Regular Record Date”) next preceding the related Interest Payment Date. The Holder must
surrender this Note to a Paying Agent to collect payment of principal. The Company will pay
principal and interest in money of the United States that at the time of payment is legal tender
for payment of public and private debts.

     3. Paying Agent, Registrar and Conversion Agent

     Initially, U.S. Bank National Association (the “Trustee”, which term shall include any
successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar
and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent
without notice to the Holder. The Company or any of its Affiliates may, subject to certain
limitations set forth in the Indenture, act as Paying Agent.

A-4

 

     4. Indenture

     This Note is one of a duly authorized issue of Securities of the Company designated as its
1.625% Senior Convertible Notes Due 2012 (the “Securities”), issued under an Indenture dated as of
June 29, 2007 (together with any supplemental indentures thereto, the “Indenture”), between the
Company and the Trustee. The terms of this Note include those stated in the Indenture and those
required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (the “TIA”), as in effect on the date of the Indenture. This Note is subject to all such
terms, and the Holder of this Note is referred to the Indenture and the TIA for a statement of
them. The Securities are limited to $300,000,000, or if the Initial Purchasers exercise the
Overallotment Option in full, $345,000,000, aggregate principal amount. The Indenture does not
limit other debt of the Company, secured or unsecured.

     Capitalized terms not otherwise defined herein have the meaning ascribed to such terms in the
Indenture.

     5. Purchase of Securities at Option of Holder Upon a Fundamental Change

     Upon a Fundamental Change, at the option of the Holder and subject to the terms and conditions
of the Indenture, the Company shall become obligated to purchase for cash all or any part specified
by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of
$1,000) of the Securities held by such Holder on the date specified by the Company in accordance
with the provisions of Article 3 of the Indenture. The purchase price of any Securities so
purchased shall equal 100% of the principal amount thereof together with accrued and unpaid
interest, if any, to, but excluding, the Fundamental Change Purchase Date. If the Fundamental
Change Purchase Date falls on a day that is after the Regular Record Date and on or prior to the
corresponding Interest Payment Date, interest, accrued and unpaid hereon to, but not including, the
applicable Fundamental Change Purchase Date, will be paid to the Holder in whose name such Note is
registered at the close of business on the Regular Record Date immediately preceding the applicable
Fundamental Change Purchase Date.

     6. Conversion

     Subject to and upon compliance with the provisions of the Indenture and upon the occurrence of
the events specified in the Indenture, the Holder may surrender for conversion all or any portion
of this Note that is in an integral multiple of $1,000. Upon conversion, the Holder shall be
entitled to receive the consideration specified in the Indenture. No fractional share of Common
Stock shall be issued upon conversion of a Note. Instead, the Company shall pay a cash adjustment
as provided in the Indenture. The initial Conversion Rate of the Securities shall be 25.1538
shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in
accordance with the provisions of Article 4 of the Indenture. If a Holder converts all or any
portion of this Note in connection with the occurrence of certain Fundamental Change transactions,
the Conversion Rate shall be increased in the manner and to the extent described in Section 4.01(i)
of the Indenture.

     Securities surrendered for conversion (in whole or in part) during the period from the close
of business on any Regular Record Date to the opening of business on the next succeeding

A-5

 

Interest Payment Date shall be accompanied by payment by the Holders of such Securities in
funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable
on such corresponding Interest Payment Date; provided that no such payment need be made: (1) in
connection with a conversion following the Regular Record Date preceding the Final Maturity Date;
(2) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record
Date and on or prior to the corresponding Interest Payment Date; or (3) to the extent of any
overdue interest, if any overdue interest exists at the time of conversion with respect to such
Note.

     A Note in respect of which a Holder has submitted a Fundamental Change Purchase Notice may be
converted only if such Holder validly withdraws such Fundamental Change Purchase Notice in
accordance with the terms of the Indenture.

     7. Denominations, Transfer, Exchange

     The Securities are in registered form, without coupons, in denominations of $1,000 principal
amount and integral multiples of $1,000 principal amount. A Holder may register the transfer of or
exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or
other governmental charges that may be imposed in relation thereto by law or permitted by the
Indenture.

     8. Persons Deemed Owners

     The Holder of a Note may be treated as the owner of it for all purposes.

     9. Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee
and any Paying Agent will pay the money back to the Company, subject to the provisions of the
Indenture. After that, Holders entitled to money must look to the Company for payment as general
creditors.

     10. Amendment, Supplement and Waiver

     Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the
Securities then outstanding, and an existing Default or Event of Default and its consequence or
compliance with any provision of the Indenture or the Securities may be waived subject to certain
exceptions with the consent of the Holders of a majority in aggregate principal amount of the
Securities then Outstanding. Without the consent of or notice to any Holder, the Company and the
Trustee may amend or supplement the Indenture or the Securities to, among other things, (x) cure
any ambiguity, omission, defect or inconsistency or (y) make any other change that does not
adversely affect the interests of the Holders in any material respect.

A-6

 

     11. Successor Entity

     When a successor corporation assumes all the obligations of its predecessor under the
Securities and the Indenture in accordance with the terms and conditions of the Indenture, the
predecessor corporation (except in certain circumstances specified in the Indenture) shall be
released from those obligations.

     12. Defaults and Remedies

     An Event of Default shall occur upon the occurrence of any of the events specified in Section
7.01(a) of the Indenture. Subject to the provisions of the penultimate paragraph of Section
7.02(c) of the Indenture, if an Event of Default shall occur and be continuing with respect to the
Securities (other than an Event of Default specified in clause (7) or (8) of Section 7.01(a) of the
Indenture), the Trustee or the Holders of not less than 25% in aggregate principal amount of the
Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare all
unpaid principal of and accrued interest on all Securities to be due and payable, by a notice in
writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any
such declaration, such principal and interest shall become due and payable immediately. If an
Event of Default specified in clause (7) or (8) of Section 7.01(a) of the Indenture occurs and is
continuing, then all the Securities shall ipso facto become and be due and payable immediately in
an amount equal to the principal amount of the Securities, together with accrued and unpaid
interest, if any, to the date the Securities become due and payable, without any declaration or
other act on the part of the Trustee or any Holder.

     The Holders of a majority in aggregate principal amount of the Securities Outstanding, by
written notice to the Company and the Trustee, may rescind and annul an acceleration and its
consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay
(1) all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation,
