or controlled by or under direct or indirect common control with such specified person. For the
purposes of this definition, “control” when used with respect to any specified person means the

consideration in the transaction or transactions consists of common stock, depositary receipts or
other certificates representing common equity interests traded or to be traded immediately
following the change of control on a U.S. national or regional securities exchange, and, as a
result of the transaction or transactions, the notes become convertible into such common stock,
depositary receipts or other certificates representing common equity interests (and any rights
attached thereto), subject to the settlement provisions of Section 10.03.

or other action provided by this Indenture to be given or taken by Holders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee and, where it is hereby expressly required, to the Company, as described in Section
12.02. Such instrument or instruments (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof
of execution of any such instrument or of a writing appointing any such agent shall



12









 







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.



     (b) The fact and date of the execution by any person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or

direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to
a Board Resolution, fix in advance a record date for the determination of Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of
outstanding Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the
outstanding Securities shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

     (c) Global Securities in General. Each Global Security shall represent such of the
outstanding Securities as shall be specified therein and each shall provide that it shall represent

outstanding Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, repurchases and conversions.

individual has ceased to hold such office prior to the authentication and delivery of such
Securities or did not hold such office at the date of authentication of such Securities.



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



     The Trustee shall authenticate and deliver the Securities for original issue in an aggregate
principal amount of up to $165,000,000 upon one or more Company Orders without any further action
by the Company. The aggregate principal amount of the Securities due at the Stated Maturity

exchange will be kept (“Registrar”). The Company may have one or more co-registrars, one or more
additional paying agents and one or more additional conversion agents. The term Paying Agent
includes any additional paying agent, including any named pursuant to Section 4.05. The term

person other than the Trustee). The agreement shall implement the provisions of this Indenture
that relate to such agent. The Company shall promptly notify the Trustee of the name and address
of any such agent. If the Company fails to maintain a Registrar, Paying Agent, or Conversion
Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor
pursuant to Section 7.07. The Company or any Subsidiary or an Affiliate of either of them may act
as Paying Agent, Registrar, Conversion Agent or co-registrar.



15









 





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



     Section 2.04 Paying Agent to Hold Money and Securities in Trust. Except as otherwise provided herein, on

the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or
shares of Common Stock sufficient to make such payments when so becoming due. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall
hold in trust for the benefit of Securityholders or the Trustee all money and shares of Common

the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall
segregate the money and shares of Common Stock held by it as Paying Agent and hold it as a separate
trust fund. The Company at any time may require a Paying Agent to pay all money and shares of
Common Stock held by it to the Trustee and to account for any funds and Common Stock disbursed by
it. Upon doing so, the Paying Agent shall have no further liability for the money or shares of
Common Stock.

other times as the Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.



     Section 2.06 Transfer and Exchange. (f) Subject to Section 2.12 hereof, upon surrender for registration of
transfer of any Security, together with a written instrument of transfer satisfactory to the
Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in
writing, at the office or agency of the Company designated as Registrar or co-registrar pursuant to
Section 2.03, the Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of any authorized
denomination or denominations, of a like aggregate principal amount. The Company shall not charge
a service charge for any registration of transfer or exchange, but the Company may require payment
of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed
in connection with the transfer or exchange of the Securities from the Securityholder requesting
such transfer or exchange.



     At the option of the Holder, Securities may be exchanged for other Securities of any
authorized denomination or denominations, of a like aggregate principal amount upon surrender of
the Securities to be exchanged, together with a written instrument of transfer satisfactory to the
Registrar duly executed by the Securityholder or such



16









 







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



     The Company shall not be required to make, and the Registrar need not register, transfers or
exchanges of Securities in respect of which a Fundamental Change Repurchase Notice has been given
and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in
the case of Securities to be purchased in part, the portion thereof not to be purchased).

outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, in whole
or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers
of a Global Security shall, except as set forth in Section 2.12, be limited to transfers of such
Global Security in whole or in part, to the Depositary, to nominees of the Depositary or to a
successor of the Depositary or such successor’s nominee.



     (c) Successive registrations and registrations of transfers and exchanges as aforesaid may be
made from time to time as desired, and each such registration shall be noted on the register for
the Securities.



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



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



     (f) No Registrar shall be required to make registrations of transfer or exchange of Securities
during any periods designated in the text of the Securities or in this Indenture as periods during
which such registration of transfers and exchanges need not be made.



     (g) Every Security (and all securities delivered in exchange therefor or in substitution
thereof) that bears or is required under this Section 2.06(g) to bear the legend set forth in this
Section 2.06(g) (the “Legend”), and any Common Stock that bears or is required under this Section
2.06(g) to bear the Common Stock legend set forth in this Section 2.06(g) (the “Common Stock
Legend”) shall be subject to the restrictions on transfer set forth in this Section 2.06(g)
(including those set forth in the legends below) unless such restrictions on transfer shall be

Stock, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on

     Until the Stated Maturity of the Securities any certificate evidencing a Security shall bear a
legend in substantially the following form, or unless otherwise agreed by the Company in writing,
with written notice thereof to the Trustee:




NEITHER THIS SECURITY NOR THE COMMON STOCK ISSUABLE ON CONVERSION OF THIS SECURITY HAS BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE
SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST
OR PARTICIPATION HEREIN OR THEREIN 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, SUCH REGISTRATION. THE HOLDER OF THIS
SECURITY, BY ITS ACCEPTANCE HEREOF, (1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL
BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”)); (2) AGREES ON ITS
OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO
OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY ONLY (A) TO INTEGRA LIFESCIENCES HOLDINGS
CORPORATION (THE “ISSUER”) OR (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE
UNDER RULE 144A, IN COMPLIANCE WITH RULE 144A TO A PERSON IT REASONABLY BELIEVES IS A
QUALIFIED INSTITUTIONAL BUYER 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; AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS
SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.



     Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under
the Securities Act (or any successor provision), any stock certificate representing shares of
Common Stock delivered upon conversion of any Security shall bear a Common Stock Legend unless such
Common Stock has been sold pursuant to a registration statement that has been declared effective
under the Securities Act by the SEC (and that continues to be effective at the time of such
transfer) or pursuant to Rule 144 under the Securities Act or any similar provision then in force,
or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee:




THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS
SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED,
TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE



18









 







DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM,
OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE
HEREOF, (1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE
144A UNDER THE SECURITIES ACT (“RULE 144A”)); (2) AGREES ON ITS OWN BEHALF AND ON BEHALF OF
ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO OFFER, SELL OR OTHERWISE
TRANSFER THIS SECURITY, BEFORE THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF
THIS SECURITY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), ONLY
(A) TO INTEGRA LIFESCIENCES HOLDINGS CORPORATION (THE “ISSUER”), (B) UNDER A REGISTRATION
STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO
BE EFFECTIVE AT THE TIME OF SUCH TRANSFER), (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE
FOR RESALE UNDER RULE 144A, IN COMPLIANCE WITH RULE 144A TO A PERSON IT REASONABLY BELIEVES
IS A QUALIFIED INSTITUTIONAL BUYER 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 OR (D) UNDER ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE ISSUER’S AND THE TRUSTEE’S RIGHT BEFORE
ANY SUCH OFFER, SALE OR TRANSFER UNDER CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF
COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM; AND (3)
AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED ON THE EARLIER OF
THE TRANSFER OF THIS SECURITY UNDER CLAUSE 2(B) ABOVE OR ON ANY TRANSFER OF THIS SECURITY
UNDER RULE 144 UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION).



     Any such shares of 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 Common Stock 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 certificate or certificates shall not bear the Common Stock Legend required by
this Section 2.06(g).



     Section 2.07 Replacement Securities. If (a) any mutilated Security is surrendered to the Trustee, or (b)
the Company and the Trustee receive evidence to their satisfaction of the



19









 







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



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



     Upon the issuance of any new Securities under this Section 2.07, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.



     Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed,
lost or stolen Security shall constitute an additional obligation of the Company and shall be
entitled to all benefits of this Indenture equally and proportionately with any and all other
Securities duly issued hereunder.



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



     Section 2.08 Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time
are all the Securities authenticated by the Trustee except for those cancelled by it, those
purchased pursuant to Section 2.07, those delivered to it for cancellation and those described in
this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the
Company, the Guarantor or an Affiliate of either holds the Security; provided, however, that in
determining whether the Holders of the requisite principal amount of Securities have given or
concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act
hereunder, Securities owned by the Company or any other obligor upon the Securities or any
Affiliate of the Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected in relying upon any
such request, demand, authorization, direction, notice, consent, waiver or other act, only
Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so
disregarded. Subject to the foregoing, only Securities outstanding at the time of such
determination shall be considered in any such determination (including, without limitation,
determinations pursuant to Article 6 and Article 9).



20









 





     If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide
purchaser.



     If the Paying Agent holds, in accordance with this Indenture, on the Business Day immediately
following a Fundamental Change Repurchase Date, or on Stated Maturity, money or securities, if
permitted hereunder, sufficient to pay Securities payable on that date, then from and after such
Fundamental Change Repurchase Date or Stated Maturity, as the case may be, such Securities shall
cease to be outstanding and Interest and Additional Amounts, if any, on such Securities shall cease
to accrue.



     If a Security is converted in accordance with Article 10, then from and after the date of
conversion, such Security shall cease to be outstanding, and Interest and Additional Amounts, if
any, shall cease to accrue and the rights of the Holders therein shall terminate (other than the
right to receive the Settlement Amount).



     Section
2.09  Temporary Securities. Pending the preparation of Certificated Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the Certificated Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the
Officers executing such Securities may determine, as conclusively evidenced by their execution of
such Securities.



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



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



21









 







Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee
in accordance with the Trustee’s customary procedure.



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



     Section
2.12 Global Securities. (m) Notwithstanding any other provisions of this Indenture or the
Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in
accordance with Section 2.06 and Section 2.12(a)(i) below, (B) transfers of a beneficial interest
in a Global Security for a Certificated Security shall comply with Section 2.06 and Section
2.12(a)(ii) below and Section 2.12(d) below, and (C) transfers of a Certificated Security shall
comply with Section 2.06, Section 2.12(a)(iii) and Section 2.12(a)(iv) below, as applicable.




     (i) Transfer of Global Security. A Global Security may not be transferred, in whole
or in part, to any person other than the Depositary or a nominee or any successor thereof,
and no such transfer to any such other person may be registered; provided that this Section
2.12(a)(i) shall not prohibit any transfer of a Security that is issued in exchange for a
Global Security but is not itself a Global Security. No transfer of a Security to any
person shall be effective under this Indenture or the Securities unless and until such
Security has been registered in the name of such person. Nothing in this Section
2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a
Global Security effected in accordance with the other provisions of this Section 2.12.




     (ii) Restrictions on Transfer of a Beneficial Interest in a Global Security for a
Certificated Security. A beneficial interest in a Global Security may not be exchanged for
a Certificated Security except upon satisfaction of the requirements set forth in this
clause (ii) below and in Section 2.12(d) below. Upon receipt by the Trustee of a request
to transfer a beneficial interest in a Global Security in accordance with Applicable
Procedures for a Certificated Security in the form satisfactory to the Trustee, together
with:




     (A) a certification, in the form set forth in Exhibit C, that such beneficial
interest in a Global Security is being transferred to a QIB in accordance with Rule
144A;




     (B) written instructions from the Holder to the Trustee to make, or direct the
Registrar to make, an adjustment on its books and records with respect to such
Global Security to reflect a decrease in the aggregate



22









 







principal amount of the Securities represented by the Global Security, such
instructions to contain information regarding the Depositary account to be
decreased; and




     (C) if the Company or the Trustee so requests, an opinion of counsel or other
evidence reasonably satisfactory to it as to the compliance with the restrictions
set forth in the Legend,




then the Trustee shall cause, or direct the Registrar to cause, in accordance with the
standing instructions and procedures existing between the Depositary and the Registrar, the
aggregate principal amount of the Securities represented by the Global Security to be
decreased by the aggregate principal amount of the Certificated Security to be issued,
shall issue such Certificated Security and shall debit or cause to be debited to the
account of the person specified in such instructions a beneficial interest in the Global
Security equal to the principal amount of the Certificated Security so issued.




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




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




     (B) to exchange such Certificated Securities for an equal principal amount of
Certificated Securities of other authorized denominations,




the Registrar shall register the transfer or make the exchange as requested if its
reasonable requirements for such transaction are met; provided, however, that the
Certificated Securities surrendered for transfer or exchange:




(1) shall be duly endorsed or accompanied by a written instrument of transfer
reasonably satisfactory to the Company and the Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing; and




(2) such Securities are being transferred or exchanged pursuant to clause (x),
(y) or (z) below, and are accompanied by the following additional information and
documents, as applicable:




     (x) if such Certificated Securities are being delivered to the Registrar
by a Holder for registration in the name of such Holder, without transfer, a
certification from such Holder to that effect; or




     (y) if such Certificated Securities are being transferred to the Company,
a certification to that effect (in the form set forth in Exhibit C); or



23









 






     (z) if such Certificated Securities are being transferred to a QIB, (i) a
certification to that effect (in the form set forth in Exhibit C, if
applicable) and (ii) if the Company or the Trustee so requests, an opinion of
counsel or other evidence reasonably satisfactory to it as to the compliance
with the restrictions set forth in the Legend.




     (iv) Restrictions on Transfer or Exchange of a Certificated Security for a Beneficial
Interest in a Global Security. A Certificated Security may not be transferred or exchanged
for a beneficial interest in a Global Security except upon satisfaction of the requirements
set forth below.




     Upon receipt by the Trustee of a Certificated Security, duly endorsed or accompanied
by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:




     (A) a certification, in the form set forth in Exhibit C, that such
Certificated Security (1) is being transferred to the Company or (2) is being
transferred to a QIB in accordance with Rule 144A;




     (B) written instructions from the Holder directing the Trustee to make, or to
direct the Registrar to make, an adjustment on its books and records with respect
to such Global Security to reflect an increase in the aggregate principal amount of
the Securities represented by the Global Security, such instructions to contain
information regarding the Depositary account to be credited with such increase; and




     (C) if the Company, or the Trustee so requests, an opinion of counsel or other
evidence reasonably satisfactory to it as to the compliance with the restrictions
set forth in the Legend,


then the Trustee shall cancel such Certificated Security and cause, or direct the Registrar to
cause, in accordance with the standing instructions and procedures existing between the Depositary
and the Registrar, the aggregate principal amount of Securities represented by the Global Security
to be increased by the aggregate principal amount of the Certificated Security to be exchanged, and
shall credit or cause to be credited to the account of the person specified in such instructions a
beneficial interest in the Global Security equal to the principal amount of the Certificated
Security so cancelled. If no Global Securities are then outstanding, the Company shall issue and
the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s
Certificate, a new Global Security in the appropriate principal amount.




     (b) Every Security shall be subject to the restrictions on transfer provided in the Legend
including the delivery of an opinion of counsel, if so required. Whenever any Restricted Security
is presented or surrendered for registration of transfer or for 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 C, dated the date of such surrender and signed by the
Holder of such Security, as to compliance with



24









 







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.



     (c) As used in Section 2.06 and this Section 2.12, the term “transfer” includes any sale,
pledge, transfer, loan, hypothecation or other disposition of any Security or share of Common Stock
or any interest therein.



     (d)





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




     (ii) Securities issued in exchange for a Global Security or any portion thereof shall
be issued in definitive, fully registered form, shall have an aggregate principal amount
equal to that of such Global Security or portion thereof to be so exchanged, shall be
registered in such names and be in such authorized denominations as the Depositary shall
designate and shall bear the applicable legends provided for herein. Any Global Security
to be exchanged in whole shall be surrendered by the Depositary to the Registrar. With
regard to any Global Security to be exchanged in part, either such Global Security shall be
so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or
its nominee with respect to such Global Security, the principal amount thereof shall be
reduced by an amount equal to the portion thereof to be so exchanged, by means of an
appropriate adjustment made on the records of the Trustee. Upon any such surrender or
adjustment, the Trustee shall authenticate



25









 







and deliver the Security issuable on such exchange to or upon the order of the
Depositary or an authorized representative thereof.




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




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




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




     (vi) Except as expressly set forth in this Indenture, including Sections 2.12(a)(ii)
and 2.12(d), none of the Trustee, any Paying Agent, Conversion Agent, the Company or the
Registrar shall have any responsibility or obligation to any beneficial owner in the Global
Securities, a member of, or a participant in the Depositary or other person with respect to
the accuracy of the records of the Depositary or its nominee or of any participant or
member thereof, with respect to any ownership interest in the Global Securities or with
respect to the delivery to any participant, member, beneficial owner or other person (other
than the Depositary) of any notice or the payment of any amount, under or with respect to
such Global Securities. All notices and communications to be given to the Holders and all
payments to be made to Holders under the Securities shall be given or made only to or upon
the order of the registered Holders (which shall be, in the case of a Global Security, the
Depositary or its nominee). The rights of beneficial owners in the Global Securities shall
be exercised only through the Depositary subject to the applicable rules and procedures of
the Depositary. Other than as set forth in this Indenture, the Trustee, any Paying Agent,
the Conversion Agent, the Company and the Registrar may rely and shall be fully protected
in relying upon information furnished by the Depositary with respect to its members,
participants and any beneficial owners. Except as expressly set forth



26









 







in this Indenture, including Sections 2.12(a)(ii) and 2.12(d), the Trustee, each
Paying Agent, the Conversion Agent, the Company and the Registrar shall be entitled to deal
with any depositary (including the Depositary), and any nominee thereof, that is the Holder
of any Global Securities as a Holder for all purposes of this Indenture relating to such
Global Securities (including the payment of principal, Interest and Additional Amounts, if
any, and the giving of instructions or directions by or to the owner or Holder of a
beneficial ownership interest in such Global Securities) as the sole Holder of such Global
Securities and shall have no obligations to the beneficial owners thereof. None of the
Trustee, any Paying Agent, the Conversion Agent, the Company or the Registrar shall have
any responsibility or liability for any acts or omissions of any such depositary with
respect to such Global Securities, for the records of any such depositary, including
records in respect of beneficial ownership interests in respect of any such Global
Securities, for any transactions between such depositary and any participant in such
depositary or between or among any such depositary, any such participant and/or any holder
or owner of a beneficial interest in such Global Securities or for any transfers of
beneficial interests in any such Global Securities.



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



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



     Section
2.13 CUSIP Numbers. The Company may issue the Securities with one or more “CUSIP,” “ISIN” or other
similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP,” “ISIN” or
other similar numbers in notices as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of a purchase and that reliance may be placed only on the
other identification numbers printed on the Securities. The Company shall promptly notify the
Trustee of any change in the CUSIP, ISIN or other similar numbers.



     Section
2.14 Payment. If any Interest Payment Date, Stated Maturity, Fundamental Change Repurchase Date,
Conversion Settlement Date or other date when payment is required to be made under this Indenture
falls on a day that is not a Business Day, then the required payment will be made on the next
succeeding Business Day with the same force and effect as if made on the date that the payment was
due, and no additional Interest will accrue on that payment for the period from and after the
Interest Payment Date, Stated Maturity, Fundamental Change Repurchase Date, Conversion Settlement
Date or other payment date, as the case may be, to that next succeeding Business Day.

Company prior to their Stated Maturity.



     Section
3.02 Repurchase of Securities at Option of the Holder Upon a Fundamental Change. (a) If a
Fundamental Change occurs, each Holder shall have the right, at such Holder’s option, to require
the Company to repurchase for cash all of such Holder’s Securities, or any portion thereof that is
equal to or an integral multiple of $1,000 principal amount, at a fundamental change repurchase
price equal to 100% of the principal amount of the Securities repurchased, plus any accrued and

following the date of the notice of a Fundamental Change mailed by the Company pursuant to Section
3.02(b) (the “Fundamental Change Repurchase Date”), subject to satisfaction by or on behalf of the
Holder of the requirements set forth in Section 3.02(c). If the Fundamental Change Repurchase Date
is on a date that is after an Interest Record Date and on or prior to the corresponding Interest
Payment Date, the Fundamental Change Repurchase Price shall be 100% of the principal amount of the
Securities repurchased and shall include accrued and unpaid Interest and accrued and unpaid
Additional Amounts, if any, to, but not including, the Fundamental Change Repurchase Date.



     (b) Within 20 calendar days after the occurrence of a Fundamental Change, the Company shall
mail a Company Notice of the Fundamental Change (substantially in the form of Exhibit D) to the
Trustee and to each Holder (and to beneficial owners if required by applicable law).
Simultaneously with providing such notice, the Company will issue a press release. The Company
Notice shall include a form of Fundamental Change Repurchase Notice to be completed by the Holder
and shall state:




     (i) briefly, the events causing a Fundamental Change and the date of such Fundamental
Change;

28









 







pursuant to Article 10 hereof only if the Fundamental Change Repurchase Notice has
been withdrawn in accordance with the terms of this Indenture;




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




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




     (x) briefly, the procedures the Holder must follow to exercise rights under this
Section 3.02;




     (xi) briefly, the conversion rights, if any, that exist on the Securities at the date
of the Company Notice and as a result of such Fundamental Change;




     (xii) the procedures for withdrawing a Fundamental Change Repurchase Notice;




     (xiii) that, unless the Company defaults in making payment of such Fundamental Change
Repurchase Price on Securities for which a Fundamental Change Repurchase Notice is
submitted, Interest and Additional Amounts, if any, on Securities surrendered for purchase
by the Company shall cease to accrue from and after the Fundamental Change Repurchase Date;
and




     (xiv) the CUSIP, “ISIN” or other similar number(s), as the case may be, of the
Securities.



     At the Company’s request, the Trustee shall give such Company Notice to each Holder in the
Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of
such Company Notice shall be prepared by the Company and such request will be made at least three
Business Days prior to the date such notice is to be provided to the Holders.



     (c) A Holder may exercise its rights specified in this Section 3.02 upon delivery of a written
notice of repurchase (a “Fundamental Change Repurchase Notice”) to the Paying Agent at any time on
or prior to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date, stating:




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



29









 






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




     (iii) that such Security shall be repurchased pursuant to the terms and conditions
specified in Section 4 of the Securities and in this Indenture.



     The delivery of such Security (together with all necessary endorsements) and the Fundamental
Change Repurchase Notice to the Paying Agent at the offices of the Paying Agent shall be a
condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor;
provided, however, that such Fundamental Change Repurchase Price shall be so paid pursuant to this
Section 3.02 only if the Security (together with all necessary endorsements) so delivered to the
Paying Agent shall conform in all respects to the description thereof set forth in the related
Fundamental Change Repurchase Notice.



     The Company shall repurchase from the Holder thereof, pursuant to this Section 3.02, a portion
of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the
repurchase of such portion of such Security.



     Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.02
shall be consummated by the delivery of the Fundamental Change Repurchase Price promptly following
the later of the Business Day following the Fundamental Change Repurchase Date or the time of
delivery of such Security (together with all necessary endorsements or notifications of book-entry
transfer).



     Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 3.02(c) shall have the right to
withdraw such Fundamental Change Repurchase Notice by delivery of a written notice of withdrawal to
the Paying Agent in accordance with Section 3.03(b) at any time prior to the close of business on
the Business Day immediately preceding the Fundamental Change Repurchase Date.



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



     Section
3.03  Effect of Fundamental Change Repurchase Notice. (d) Upon receipt by the Paying Agent of the
Fundamental Change Repurchase Notice specified in Section 3.02, the Holder of the Security in
respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental
Change Repurchase Notice is withdrawn as specified in Section 3.03(b)) thereafter be entitled
solely to receive the Fundamental Change Repurchase Price with respect to such Security whether or
not the Security is, in fact, properly delivered. Such Fundamental Change Repurchase Price shall
be paid to such Holder, subject to receipt of funds and/or securities by the Paying Agent, promptly
following the later of (x) the Business Day following the Fundamental Change Repurchase Date with
respect to such Security (provided the conditions in



30









 







Section 3.02 have been satisfied) and (y) the time of delivery of such Security to the Paying
Agent by the Holder thereof in the manner required by Section 3.02. Securities in respect of which
a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted
pursuant to and to the extent permitted by Article 10 hereof on or after the date of the delivery
of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has
first been validly withdrawn as specified in Section 3.03(b).



     (b) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent at any time, if received by the Paying Agent
prior to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date specifying:




	 	(1)	 	the principal amount, if any, of such Security which remains subject to
the original Fundamental Change Repurchase Notice and which has been or shall be
delivered for purchase by the Company,
	 
	 	(2)	 	if Certificated Securities have been issued, the certificate number, if
any, of the Security in respect of which such notice of withdrawal is being
submitted (or, if Certificated Securities have not been issued, that such withdrawal
notice shall comply with the appropriate Depositary procedures), and
	 
	 	(3)	 	the principal amount of the Security at maturity with respect to which
such notice of withdrawal is being submitted.





     Section
3.04  Deposit of Fundamental Change Repurchase Price. Prior to 11:00 a.m. (local time in the City
of New York) on the Business Day following the Fundamental Change Repurchase Date the Company shall
deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them
is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an
amount of cash in immediately available funds sufficient to pay the aggregate Fundamental Change
Repurchase Price of all the Securities or portions thereof which are to be purchased as of the
Fundamental Change Repurchase Date.



     Section
3.05  Securities Purchased in Part. Any Certificated Security which is to be purchased only in part
(but any such partial purchase shall be in minimum principal amounts equal to $1,000 or an integral
multiple of $1,000) shall be surrendered at the office of the Paying Agent (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing) and 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 any
authorized denomination as requested by such Holder in aggregate principal amount equal to, and in
exchange for, the portion of the principal amount of the Security so surrendered which is not
purchased.

     Section
3.06  Covenant to Comply with Securities Laws upon Purchase of Securities. When complying with the
provisions of Section 3.02 hereof (provided that such offer or purchase constitutes an “issuer
tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor
provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to
any exemptions available under applicable law, the Company shall, if then applicable, (i) comply
with Rule 13e-4 and Rule 14e-1 (or any successor provision) and any other applicable tender offer
rules under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or
report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities
laws so as to permit the rights and obligations under Section 3.02 to be exercised in the time and
in the manner specified in Section 3.02.



     Section
3.07  Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any
cash that remains unclaimed as provided in Section 9 of the Securities, together with interest, if
any, thereon (subject to the provisions of Section 7.01(f)), held by them for the payment of the
Fundamental Change Repurchase Price.



ARTICLE 4

Covenants




     Section
4.01  Payment of Securities. The Company shall make all payments in respect of the Securities on
the dates and in the manner provided in the Securities or pursuant to this Indenture. Any amounts
of cash in immediately available funds or shares of Common Stock to be given to the Trustee or
Paying Agent shall be deposited with the Trustee or Paying Agent by 11:00 a.m., New York City time,
by the Company on the applicable payment date. The principal amount of, and Interest and
Additional Amounts, if any, on the Securities, and the Fundamental Change Repurchase Price and
amounts payable on conversion shall be considered paid on the applicable date due if on such date
(which, in the case of a Fundamental Change Repurchase Price, shall be on the Business Day
immediately following the applicable Fundamental Change Repurchase Date) the Trustee or the Paying
Agent holds, in accordance with this Indenture, cash or securities, if permitted hereunder,
sufficient to pay all such amounts then due.



     Section
4.02  SEC and Other Reports. The Company shall deliver to the Trustee, within 15 days after it is
required to file such annual and quarterly reports, information, documents and other reports with
the SEC, copies of its annual report and of the information, documents and other reports (or copies
of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which
the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act;
provided, however, that, to the extent permitted by law, any such document, information and other
reports filed and publicly available through the SEC’s EDGAR filing system shall be deemed to have
been received by the Trustee. The Company shall also comply with the other provisions of TIA
Section 314(a). Delivery of such reports, information 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



32









 







covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s
Certificates).



     Section
4.03  Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the
end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2007) an
Officer’s Certificate, stating whether or not to the knowledge of the signer thereof, the Company
is in default in the performance and observance of any of the terms, provisions and conditions of
this Indenture (without regard to any period of grace or requirement of notice provided hereunder)
and if the Company shall be in default, specifying all such defaults and the nature and status
thereof of which such Officer may have knowledge and otherwise comply with Section 314(a)(4) of the
TIA.



     The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee,
within 30 days of any executive officer of the Company becoming aware of any Default or Event of
Default, an Officer’s Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.



     Section
4.04  Further Instruments and Acts. The Company shall 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
4.05  Maintenance of Office or Agency. The Company shall maintain an office or agency of the
Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or
surrendered for payment, where Securities may be surrendered for registration of transfer,
exchange, purchase or conversion and where notices and demands to or upon the Company and the
Guarantor in respect of the Securities and this Indenture may be served. The office of the
Trustee, located at 213 Court Street, Suite 703, Middletown, Connecticut 06457, shall initially be
such office or agency for all of the aforesaid purposes. Such office or agency need not be the
principal securities clearance or processing office of the Trustee. The Company shall give prompt
written notice to the Trustee of the location, and of any change in the location, of any such
office or agency (other than a change in the location of the office of the Trustee). If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the address of the Trustee set forth in Section 12.02.



     The Company may also from time to time designate one or more other offices or agencies where
the Securities may be presented or surrendered for any or all such purposes and may from time to
time rescind such designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency for such purposes.



     Section
4.06  Delivery of Certain Information. At any time when the Company is not subject to Section 13 or
15(d) of the Exchange Act until such time as neither the Securities nor any shares of Common Stock
issued upon conversion of the Securities are “restricted securities” within the meaning of Rule 144
of the Securities Act, upon the request of a



33









 







Holder or any beneficial owner of Securities or Holder or beneficial owner of shares of Common
Stock issued upon conversion thereof, the Company shall promptly furnish or cause to be furnished
Rule 144A Information (as defined below) to such Holder or any beneficial owner of Securities or
Holder or beneficial owner of shares of Common Stock issued upon conversion thereof, or to a
prospective purchaser of any such security designated by any such Holder or beneficial owner, as
the case may be, to the extent required to permit compliance by such Holder or beneficial owner
with Rule 144A in connection with the resale of any such security. “Rule 144A Information” shall be
such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act. Whether a
person is a beneficial owner shall be determined by the Company to the Company’s reasonable
satisfaction.



     Section 4.07
Additional Amounts Notice. In the event that the Company is required to pay Additional
Amounts to Holders of Securities pursuant to the Registration Rights Agreement, the Company shall
provide written notice (“Additional Amounts Notice”) to the Trustee of its obligation to pay
Additional Amounts prior to the required payment date for the Additional Amounts, and the
Additional Amounts Notice shall set forth the amount of Additional Amounts to be paid by the
Company on such payment date. The Trustee shall not at any time be under any duty to any Holder of
Securities to determine the Additional Amounts, or with respect to the nature, extent or
calculation of the amount of Additional Amounts when made, or with respect to the method employed
in such calculation of the Additional Amounts.



     Section 4.08
Resale of the Securities. During the period of two years after the last date of original
issuance of the Securities, the Company shall not, and shall not permit any of its Affiliates to,
resell any of the Securities that constitute “restricted securities” under Rule 144 under the
Securities Act that have been reacquired by any of them.



ARTICLE 5

Successor Company




     Section 5.01
When Company May Merge or Transfer Assets. The Company shall not consolidate with or merge
with or into any other person or convey, transfer or lease all or substantially all its assets to
another person, unless:




     (a) the resulting, surviving or transferee Person (the “successor company”) shall be a
corporation organized and existing under (i) the laws of the United States of America, any
State thereof or the District of Columbia, or (ii) any other jurisdiction so long as the
successor company agrees to submit to service of process in any State in the United States
of America or the District of Columbia and, in the case of clause (ii) above, the successor
company provides a full and unconditional indemnity and provision for additional amounts
for any incremental amounts required to be withheld from payments or deliveries to Holders
or beneficial owners of the Securities under applicable foreign laws, rules, regulations or
authorities, and any other incremental tax liabilities or costs of such Holders or
beneficial owners as a result of such merger or other transaction, and,



34









 







in each case, the successor company (if not the Company) will expressly assume, by a
supplemental indenture, executed and delivered to the Trustee, in form reasonably
satisfactory to the Trustee, all of the Company’s obligations under the Securities and this
Indenture;




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




     (c) the Company shall have delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that such consolidation, merger or transfer and, if a
supplemental indenture is required in connection with such transaction, such supplemental
indenture, comply with this Article 5.



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



     The successor company formed by such consolidation or into which the Company is merged or the
successor company to which such conveyance, transfer, lease or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor had been named as the Company herein; and
thereafter, except for obligations, if any, that the Company may have under a supplemental
indenture, the Company shall be discharged from all obligations and covenants under this Indenture
and the Securities. Subject to Section 9.06, the Company, the Trustee and the successor company
shall enter into a supplemental indenture to evidence the succession and substitution of such
successor company and such discharge and release of the Company. For the avoidance of doubt, a
transfer of assets or a merger or consolidation among the Company’s wholly-owned Subsidiaries shall
not be deemed to be a transfer of all or substantially all of the Company’s assets for purposes of
this Section 5.01.



ARTICLE 6

Defaults and Remedies




     Section 6.01
Events of Default. So long as any Securities are outstanding, each of the following shall be
an “Event of Default”:



     (a) following the exercise by the Holder of the right to convert a Security in accordance with
Article 10 hereof, the Company fails to comply with its obligations to deliver the cash or shares
of Common Stock, if any, required to be delivered as part of the applicable Settlement Shares or
Settlement Amount on the applicable Conversion Settlement Date;



35









 





     (b) the Company defaults in its obligation to provide timely notice of a Fundamental Change to
the Trustee and each Holder as required under Section 3.02(b);



     (c) default in the payment of the principal amount of any Security when due at maturity, upon
repurchase or otherwise (including, without limitation, upon the exercise by a Holder of its right
to require the Company to repurchase such Securities pursuant to and in accordance with Section
3.02 hereof);



     (d) default in the payment of any Interest, including Additional Amounts, if any, when due and
payable, and continuance of such default for a period of 30 days past the applicable due date;



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



     (f) the Company or any of its Subsidiaries default in the payment of the principal or interest
on any mortgage, agreement or other instrument under which there may be outstanding, or by which
there may be secured or evidenced, any of the Company’s indebtedness or indebtedness of any of its
Subsidiaries for money borrowed in excess of $10.0 million or its foreign currency equivalent,
whether such indebtedness now exists or shall hereafter be created, resulting in such indebtedness
becoming or being declared due and payable, and such acceleration shall not have been rescinded or
annulled within 10 days after written notice to the Company from the Trustee or to the Company and
the Trustee from the Holders of at least 25% in aggregate principal amount of the Securities at the
time outstanding has been received by the Company or such Subsidiary;



     (g) the Company or any of its Significant Subsidiaries fails to pay final judgments
aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed for a
period of 60 days;



     (h) the entry by a court having jurisdiction in the premises of (i) a decree or order for
relief in respect of the Company or any of its Significant Subsidiaries, in an involuntary case or
proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law (any
“Bankruptcy Law”) or (ii) a decree or order adjudging the Company or any Significant Subsidiary, a
bankrupt or insolvent, or approving as properly filed a petition seeking reorganization,
arrangement, adjustment or composition of or in respect of the Company or any Significant
Subsidiary, under any applicable Bankruptcy Law, or appointing a custodian, receiver, liquidator,
assignee, trustee, sequestrator or other similar official of the Company or any Significant
Subsidiary or of any substantial part of any of their property, or ordering the winding up or
liquidation of its affairs, and the continuance of any such decree or order for relief or any such
other decree or order described in clause (i) or (ii) above is unstayed and in effect for a period
of 60 consecutive days;



36









 





     (i) (i) the commencement by the Company or any Significant Subsidiary, of a voluntary case or
proceeding under any applicable Bankruptcy Law or of any other case or proceeding to be adjudicated
a bankrupt or insolvent, or (ii) the consent by the Company or any Significant Subsidiary, to the
entry of a decree or order for relief in respect of the Company or any Significant Subsidiary, in
an involuntary case or proceeding under any applicable Bankruptcy Law or to the commencement of any
bankruptcy or insolvency case or proceeding against the Company or any Significant Subsidiary, or
(iii) the filing by the Company or any Significant Subsidiary, of a petition or answer or consent
seeking reorganization or relief under any applicable Bankruptcy Law, or (iv) the consent by the
Company or any Significant Subsidiary to the filing of such petition or to the appointment of or
the taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or
other similar official of the Company or any Significant Subsidiary or of any substantial part of
any of their property, or (v) the making by the Company or any Significant Subsidiary, of a general
assignment for the benefit of creditors, or the admission by the Company or any Significant
Subsidiary, in writing of its inability to pay its debts generally as they become due; and



     (j) the Guarantee ceases to be in full force and effect (except as contemplated by the terms
thereof) or the Guarantor or any person acting by or on behalf of the Guarantor denies or
disaffirms the Guarantor’s obligations under the Guarantee or Article 11, and such default
continues for 10 days after receipt by the Company of a Notice of Default.



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



     For the avoidance of doubt, clauses (e) and (j) above shall not constitute an Event of Default
until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal
amount of the Securities at the time outstanding notify the Company and the Trustee, of such
default and the Company does not cure such default (and such default is not waived) within the time
specified in clause (e) or (j), as applicable, above (subject to the provisions of the immediately
succeeding paragraph) after actual receipt of such notice. Any such notice must specify the
default, demand that it be remedied and state that such notice is a “Notice of Default.”



     Notwithstanding anything to the contrary in this Indenture, to the extent elected by the
Company in its sole discretion, the sole remedy for an Event of Default described in clause (e)
above relating to the failure to comply with Section 4.02 hereof or the failure to comply with
Section 314(a)(1) of the TIA, if applicable, will (A) for the first 60 days after the occurrence of
such an Event of Default, consist exclusively of the right to receive additional interest on the
Securities at an annual rate equal to 0.25% of the principal amount of the Securities and (B) for
the period from the 61st day after the occurrence of such an Event of Default to the 120th day
after the occurrence of such an Event of Default, consist exclusively of the right to receive
additional interest on the Securities at an annual rate equal to 0.50% of the principal amount of
the Securities (the



37









 




“additional interest”). This additional interest will be in addition to any Additional
Amounts on the Securities that may accrue as a result of a Registration Default (as defined in the
Registration Rights Agreement) and will be payable on the same dates and in the same manner as
Interest accruing on the Securities. The additional interest will accrue on all outstanding
Securities from and including the date on which an Event of Default relating to the failure to
comply with Section 4.02 hereof or the failure to comply with Section 314(a)(1) of the TIA first
occurs to, but not including, the 120th day thereafter (or such earlier date on which the Event of
Default relating to the failure to comply with Section 4.02 or the failure to comply with Section
314(a)(1) of the TIA shall have been cured or waived). On such 120th day (or earlier, if the Event
of Default relating to the failure to comply with Section 4.02 or the failure to comply with
Section 314(a)(1) of the TIA is cured or waived prior to such 120th day), such additional interest
will cease to accrue and, if the Event of Default relating to the failure to comply with Section
4.02 or the failure to comply with Section 314(a)(1) of the TIA has not been cured or waived prior
to such 120th day, the Securities will be subject to acceleration as provided in Section 6.02
hereof. The provisions of this paragraph will not affect the rights of Holders of Securities in
the event of the occurrence of any other Event of Default. In the event the Company does not
timely elect to pay the additional interest upon an Event of Default relating to the failure to
comply with Section 4.02 or the failure to comply with Section 314(a)(1) of the TIA in accordance
with this paragraph, the Securities will be subject to acceleration as provided in Section 6.02
hereof. To make such election, the Company must notify the Holders, the Trustee and the Paying
Agent of such election on or prior to the date such failure to comply with Section 4.02 or the
failure to comply with Section 314(a)(1) of the TIA becomes an Event of Default.




     Section 6.02
Acceleration. Subject to the final paragraph of Section 6.01, if an Event of Default (other
than an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the
Company) occurs and is continuing (the Event of Default not having been cured or waived), the
Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of
the Securities at the time outstanding by notice to the Company and the Trustee, may declare the
principal amount of the Securities and any accrued and unpaid Interest and any accrued and unpaid
Additional Amounts, if any, on all the Securities to be immediately due and payable. Upon such a
declaration, such accelerated amount shall be due and payable immediately. If an Event of Default
specified in Section 6.01(h) or Section 6.01(i) with respect to the Company occurs and is
continuing, the principal amount of the Securities and any accrued and unpaid Interest and accrued
and unpaid Additional Amounts, if any, on all the Securities shall become and be immediately due
and payable without any declaration or other act on the part of the Trustee or any Securityholders.
The Holders of a majority in aggregate principal amount of the Securities at the time outstanding,
by notice to the Trustee and the Company (and without notice to any other Securityholder) may
rescind an acceleration and its consequences, and thereby waive the Events of Default giving rise
to such acceleration, if the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of the principal amount of
the Securities and any accrued and unpaid Interest and any accrued and unpaid Additional Amounts,
if any, that have become due solely as a result of acceleration, which amounts, if such rescission
is effective, shall no longer be payable as a result of



38









 







acceleration. No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereto.



     Section 6.03
Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of the principal amount of the Securities and any accrued
and unpaid Interest and accrued and unpaid Additional Amounts, if any, on the Securities or to
enforce the performance of any provision of the Securities, the Guarantee or this Indenture.



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



     Section 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the
Securities at the time outstanding, by notice to the Trustee (and without notice to any other
Securityholder), may waive any existing or past Default and its consequences except (1) an Event of
Default described in clauses (a), (c) and (d) of Section 6.01 or (2) an Event of Default in respect
of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder
affected, which, in each case may be waived only upon the written consent of each affected Holder.
When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or
other Default or impair any consequent right. This Section 6.04 shall be in lieu of Section
316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) is hereby expressly excluded from this
Indenture, as permitted by the TIA.



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



     Section 6.06 Limitation on Suits. A Securityholder may not pursue any remedy with respect to this
Indenture, the Securities or the Guarantee, except in the case of a Default due to the non-payment
of the principal amount of the Securities, any accrued and unpaid Interest, any accrued and unpaid
Additional Amounts or any unpaid Settlement Amounts or Settlement Shares, unless:




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




39









 






	 	(2)	 	the Holders of at least 25% in aggregate principal amount of the
Securities at the time outstanding make a written request to the Trustee to pursue
the remedy;
	 
	 	(3)	 	the Trustee does not comply with the request within 60 days after receipt
of such notice, request and offer of security or indemnity; and
	 
	 	(4)	 	the Holders of a majority in aggregate principal amount of the Securities
at the time outstanding do not give the Trustee a direction inconsistent with the

of such Holder.

whether the principal amount of the Securities and any accrued and unpaid Interest and accrued and
unpaid Additional Amounts, if any, in respect of the Securities shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of any such amount) shall be entitled and empowered,

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

making of such payments directly to the Holders, to pay the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 7.07.



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

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



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



     Section

Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a
court in its discretion may require the filing by any party litigant (other than the Trustee) in
the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or defenses made by the
party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the
Securities at the time



41









 







outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and such Section
315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

and unpaid Interest and accrued and unpaid Additional Amounts, if any, on Securities, as
contemplated herein, or which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of

     Section
7.01 Duties of Trustee.



     (a) If 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
their exercise as a prudent person would exercise or use under the circumstances in the conduct of
such person’s own affairs.



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




	 	(1)	 	the Trustee need perform only those duties that are
specifically set forth in this Indenture and no others, and no implied duties

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




42









 











     (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 Section 7.01(c) does not limit the effect of Sections
7.01(b) and 7.01(g);
	 
	 	(2)	 	the Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer unless it is proved that the

hereunder shall be the property of the Company).



     (g) No provision of this Indenture shall require the Trustee to expend or risk its own funds

assured to it.

comply with Section 7.10 and Section 7.11.

responsibility for, the validity or adequacy of this Indenture, the Guarantee or the Securities, it
shall not be accountable for the Company’s use or application by the Company of the Securities or

to receive any notices hereunder.



     Section

case of a Default or Event of Default described in clause (c) or (d) of Section 6.01, the Trustee
may withhold the notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interest of the Securityholders. The preceding
sentence shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby
expressly excluded from this Indenture, as permitted by the TIA.



45









 





     Section
7.06 Reports by Trustee to Holders. Within 60 days after each December 31 beginning with December

that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall

mail to Securityholders pursuant to TIA Section 313(c).



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



     Section
7.07 Compensation and Indemnity. The Company agrees:




     (a) to pay to the Trustee from time to time such compensation as the Company and the
Trustee shall from time to time agree in writing for all services rendered by it hereunder
(which compensation shall not be limited (to the extent permitted by law) by any provision
of law in regard to the compensation of a trustee of an express trust);




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




     (c) to indemnify and hold the Trustee and its directors, officers, agents and
employees (collectively, the “Indemnitees”) harmless from and against any and all claims,
liabilities, losses, damages, fines, penalties and expenses, including out-of-pocket,
incidental expenses, legal fees and expenses and the allocated costs and expenses of
in-house counsel and legal staff (“Losses”) that may be imposed on, incurred by or asserted
against the Indemnitees or any of them for following any instruction or other direction
upon which the Trustee is authorized to rely pursuant to the terms of this Indenture. In
addition to and not in limitation of the immediately preceding sentence, the Company also
agrees to indemnify and hold the Indemnitees and each of them harmless from and against any
and all Losses that may be imposed on, incurred by or asserted against the Indemnitees or
any of them in connection with or arising out of the Trustee’s performance under this
Indenture, provided the Trustee has not acted with negligence or engaged in willful
misconduct.



     To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a
lien prior to the Securities on all money or property held or collected by the Trustee, except that
held in trust to pay the principal amount of, or the Fundamental Change Repurchase Price, Interest
or Additional Amounts, if any, as the case may be, on particular Securities.



46









 





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



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



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




	 	(1)	 	the Trustee fails to comply with Section 7.10;
	 
	 	(2)	 	the Trustee is adjudged bankrupt or insolvent;
	 
	 	(3)	 	a receiver or public officer takes charge of the Trustee or its property;
or
	 
	 	(4)	 	the Trustee otherwise becomes incapable of acting.





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



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



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



47









 





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



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



     Section
7.09 Successor Trustee by Merger. Any corporation or association into which the Trustee in its
individual capacity may be merged or converted or with which it may be consolidated or to which it
transfers all or substantially all of its corporate trust business or assets, or any corporation or
association resulting from any merger, conversion or consolidation to which the Trustee in its
individual capacity may be sold or otherwise transferred, shall be the Trustee hereunder without
further act.



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



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

ARTICLE 10

Conversions




     Section
10.01 Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article
10, a Holder of a Security shall have the right, at such Holder’s option, to convert all or any
portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof)
of such Security prior to the close of business on the third Business Day immediately preceding
Stated Maturity into cash and shares of Common Stock, if applicable, based on the Applicable
Conversion Rate only as follows:




(1) during any fiscal quarter of the Company (a “Fiscal Quarter”) commencing
after September 30, 2007 (and only during such Fiscal Quarter), if the Closing Sale
Price of the Common Stock for each of at least 20 Trading Days during the period of
30 consecutive Trading Days ending on the last Trading Day of the immediately
preceding Fiscal Quarter is more than 130% of the Applicable Conversion Price in
effect on such last Trading Day;




(2) during the five Business Days immediately following any five consecutive
Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000
principal amount of the Securities (as



52









 







determined following a request by a Holder of the Securities in accordance
with the procedures described below) for each day of such Measurement Period was
less than 97% of the product of the Closing Sale Price of the Common Stock and the
Applicable Conversion Rate on each such day. The shall have no obligation to
determine the Trading Price of the Securities unless requested to do so in writing
by a Holder of the Security. Upon making any such request, any such requesting
Holder shall provide reasonable evidence that (A) such requesting Holder is a
Holder of the Security as of the date of such notice, and (B) the Trading Price per
$1,000 principal amount of Securities would be less than 97% of the product of the
Closing Sale Price of the Common Stock and the Applicable Conversion Rate on that
day. At such time, the Company shall determine the Trading Price of the Securities
beginning on the next Trading Day and on each successive Trading Day until the
Trading Price per $1,000 original principal amount of the Securities is greater
than or equal to 97% of the product of the Closing Sale Price of the Common Stock
and the Applicable Conversion Rate;




(3) any time on or after December 15, 2009 and prior to the close of business
on the third Business Day immediately preceding Stated Maturity;




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



     The Company or, if applicable, the Conversion Agent (in the case of a conversion pursuant to
clause (1) above) shall determine on a daily basis during the time periods specified in Section
10.01(a)(1) or, following a request by a Holder of Securities in accordance with the procedures
specified in Section 10.01(a)(2), whether the Securities shall be convertible as a result of the
occurrence of an event specified in such Sections and, if the Securities shall be so convertible,
the Company or the Conversion Agent, as applicable, shall promptly deliver to the Conversion Agent,
the Trustee or the Company, as applicable, written notice thereof. Whenever the Securities shall
become convertible pursuant to this Section 10.01 (as determined in accordance with this Section
10.01), the Company or, at the Company’s request, the Trustee in the name and at the expense of the
Company, shall promptly notify the Holders of the event triggering such convertibility in the
manner provided in Section 12.02, or the Company shall (i) promptly disseminate a press release and
use its reasonable efforts to post the information on its website or otherwise publicly disclose
the information or (ii) provide notice to the Holders in a manner contemplated by this Indenture,
including through the facilities of DTC. Any notice so given shall be conclusively presumed to
have been duly given, whether or not the Holder receives such notice.



     (b) In the event that:




(1) (A) the Company distributes to all or substantially all holders of Common
Stock any rights or warrants entitling them to purchase, for a period expiring
within 60 days after the date of such distribution, Common



53









 







Stock at less than the average of the Closing Sale Prices of the Common Stock
for the 10 consecutive Trading Days ending on the Trading Day immediately preceding
the public announcement date for such distribution; or (B) the Company distributes
to all or substantially all holders of Common Stock cash, debt securities, rights
or warrants to purchase the Company’s securities, or other assets (excluding
dividends or distributions described in Section 10.04(a)), which distribution has a
per share value as determined by the Board of Directors exceeding 15% of the
average of the Closing Sale Prices of the Common Stock for the 10 consecutive
Trading Days ending on the Trading Day immediately preceding the public
announcement date of such distribution, then, in either case, the Securities may be
surrendered for conversion at any time on and after the date that the Company gives
notice to the Holders of such distribution, which shall be not less than 30
calendar days prior to the Ex-Dividend Date for such distribution, until the
earlier of the close of business on the Business Day immediately preceding the
Ex-Dividend Date for such distribution or the date on which the Company announces
that such distribution shall not take place, even if the Securities are not
otherwise convertible at such time; provided that no Holder of a Security shall
have the right to convert its Securities if the Holder is entitled to participate
in such distribution (based on the Applicable Conversion Rate) without conversion;
or




(2) a Fundamental Change occurs (regardless of whether Holders have a right to
require the Company to repurchase the Securities upon such Fundamental Change as
set forth in Article 3), then the Securities may be surrendered for conversion at
any time from and after the date that is 30 calendar days prior to the anticipated
effective date of such transaction until and including the date that is 30 calendar
days after the actual effective date of such transaction (or, if such transaction
also constitutes a Fundamental Change pursuant to which Holders have a right to
require the Company to repurchase the Securities pursuant to Section 3.02, until
the close of business on the Business Day immediately preceding the applicable
Fundamental Change Repurchase Date). The Company shall notify Holders and the
Trustee as promptly as practicable following the date that it publicly announces
the Fundamental Change transaction giving rise to the above conversion right (but
in no event less than 30 calendar days prior to the anticipated effective date of
such transaction).




(3) If a Fundamental Change pursuant to clause (1) or (3) of the definition
thereof occurs prior to Stated Maturity and a Holder elects to convert its
Securities in connection with such Fundamental Change (regardless of whether such
Holder has the right to require the Company to repurchase its Securities as set
forth in Article 3), the Applicable Conversion Rate shall be increased to effect
the delivery of an additional number of shares of Common Stock (the “Additional
Shares”) as described below; provided that if the Stock Price paid in connection
with



54









 







such Fundamental Change is less than $51.97 or greater than $150.00 (subject
in each case to adjustment as described below), no Additional Shares shall be added
to the Applicable Conversion Rate. A conversion of the Securities will be deemed
for these purposes to be “in connection with” a Fundamental Change if the
Conversion Notice is received by the Conversion Agent from and including the date
that is 30 calendar days prior to the anticipated effective date of the Fundamental
Change to the close of business on the Business Day immediately preceding the
applicable Fundamental Change Repurchase Date.



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



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



     Notwithstanding the foregoing, in no event shall the total number of shares issuable upon
conversion of Securities exceed 19.2418 per $1,000 principal amount of Securities, in each case,
subject to adjustments in the same manner as the Applicable Conversion Rate as set forth in Section
10.04 and subject to Section 10.05.



     Section
10.02 Conversion Procedure; Applicable Conversion Rate; Fractional Shares. (c) Subject to the
Company’s rights under Section 10.01 and Section 10.03, each Security shall be convertible at the
office of the Conversion Agent into a combination of cash and fully paid and nonassessable shares
(calculated to the nearest 1/10,000th of a share) of Common Stock, if any, at a rate (the
“Applicable Conversion Rate”) equal to, initially, 15.0917 shares of Common Stock for each $1,000
principal amount of Securities. The Applicable Conversion Rate shall be adjusted in certain
instances as provided in Section 10.04 hereof, but shall not be adjusted for any accrued and unpaid
Interest or Additional Amounts, if any. Upon conversion, no payment shall be made by the Company
with respect to any accrued and unpaid Interest, including Additional Amounts, if any, unless, as
described below, such conversion occurs between an Interest Record Date and the



55









 







Interest Payment Date to which such Interest Record Date relates, in which case the Holders of
the Securities on the Interest Record Date shall receive accrued and unpaid interest, including
Additional Amounts, if any, payable on the Securities on the applicable Interest Payment Date.
Instead, such amount shall be deemed paid by the applicable Settlement Amount or Settlement Shares,
as applicable, delivered upon conversion of any Security. In addition, no payment shall be made in
respect of dividends on the Common Stock with a record date prior to the Conversion Date. The
Company shall not issue any fraction of a share of Common Stock in connection with any conversion
of Securities, but instead shall, subject to Section 10.03 hereof, make a cash payment (calculated
to the nearest cent) equal to such fraction multiplied by the Daily VWAP on the final Trading Day
of the Cash Settlement Averaging Period or, if the Company has made a valid Physical Settlement
Election, on the third Scheduled Trading Day before the Conversion Settlement Date.



     (b) At any time before December 15, 2009, the Company may irrevocably make a Physical
Settlement Election as set forth in Section 10.03(b).



     (c) Before any Holder of a Security shall be entitled to convert the same, such Holder shall
(1) in the case of Global Securities, comply with the procedures of the Depositary in effect at
that time for converting a beneficial interest in a Global Security, and in the case of
Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at
the office of the Conversion Agent, and (2) give written notice to the Company in the form on the
reverse of such Certificated Security (the “Conversion Notice”) at said office or place that such
Holder elects to convert the same and shall state in writing therein the principal amount of
Securities to be converted (which shall be equal to or an integral multiple of $1,000 principal
amount) and the name or names (with addresses) in which such Holder wishes the certificate or
certificates for Common Stock included in the Settlement Amount, if any, or Settlement Shares, as
applicable, to be registered.



     Before any such conversion, a Holder also shall pay all taxes or duties, if any, as provided
in Section 10.07 and any amount payable pursuant to Section 10.02(h).



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



     (d) A Security shall be deemed to have been converted immediately before the close of business
on the date (the “Conversion Date”) that the Holder has complied with Section 10.02(c).



     (e) The Company shall, on the Conversion Settlement Date, to the extent applicable as set
forth in Section 10.03, (i) pay the cash component (including cash in lieu of any fraction of a
share to which such Holder would otherwise be entitled) of the Conversion Obligation determined
pursuant to Section 10.03 to the Holder of a Security surrendered for conversion, or such Holder’s
nominee or nominees, and (ii) issue, or



56









 







cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s
nominee or nominees, certificates for the number of full shares of Common Stock, if any, to which
such Holder shall be entitled as part of such Conversion Obligation. The Company shall not be
required to deliver certificates for shares of Common Stock while the stock transfer books for such
stock or the security register are duly closed for any purpose, but certificates for shares of
Common Stock shall be issued and delivered as soon as practicable after the opening of such books
or security register, and the person or persons entitled to receive the Common Stock as part of the
applicable Settlement Amount or Settlement Shares, as applicable, upon such conversion shall be
treated for all purposes as the record holder or holders of such Common Stock, as of the close of
business on the applicable Conversion Settlement Date.



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



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



     (h) If a Securityholder delivers a Conversion Notice after the Interest Record Date for a
payment of Interest (including Additional Amounts, if any) but prior to the corresponding Interest
Payment Date, such Securityholder must pay to the Company, at the time such Securityholder
surrenders Securities for conversion, an amount equal to the Interest (including Additional
Amounts, if any), that has accrued and shall be paid on the related Interest Payment Date. The
preceding sentence shall not apply if (1) the Company has specified a Fundamental Change Repurchase
Date that is after the close of business on an Interest Record Date but on or prior to the
corresponding Interest Payment Date, (2) to the extent of overdue Interest (and any overdue
Additional Amounts), if any overdue Interest (and any overdue Additional Amounts) exists at the
time of conversion with respect to the Securities converted or (3) if a Holder converts its
Securities on or after December 15, 2009.



     Section 10.03  Payment Upon Conversion. (k) In the event that the Company has not made a Physical Settlement
Election as set forth in clause (b) below, upon conversion of Securities, the Company shall satisfy
its obligation to convert the Securities (the “Conversion Obligation”) by delivering to Holders
surrendering Securities for conversion, for each $1,000 principal amount of Securities, a
settlement amount (the “Settlement Amount”) equal to the sum of the Daily Settlement Amounts for
each of the 50 consecutive Trading Days of the related Cash Settlement Averaging Period.



57









 






     (i) The “Daily Settlement Amount” for each of the 50 consecutive Trading Days of the
related Cash Settlement Averaging Period, shall consist of:




     (A) cash equal to the lesser of $20 and the Daily Conversion Value on such
Trading Day; and




     (B) to the extent the Daily Conversion Value on such Trading Day exceeds $20,
a number of shares of Common Stock equal to (x) the difference between such Daily
Conversion Value for such Trading Day and $20 (such difference being referred to as
the “Daily Excess Amount”), divided by (y) the Daily VWAP for such Trading Day (or
the consideration into which the Common Stock has been converted as described in
Section 10.06); provided that no fractional shares shall be issued, and in lieu
thereof, the Company shall pay an amount in cash as set forth in Section 10.02
above.




     (ii) The Settlement Amount will be delivered on the Conversion Settlement Date.



     (b) At any time before December 15, 2009, the Company may irrevocably make a Physical
Settlement Election, in its sole discretion and without the consent of the Holders, by valid
delivery of a Physical Settlement Election Notice, to satisfy all Conversion Obligations arising
out of conversions of Securities after the Physical Settlement Election Date. In addition to the
giving of such Physical Settlement Election Notice, the Company shall disseminate a press release
through Dow Jones & Company, Inc. or Bloomberg Business News or another newswire service announcing
such Physical Settlement Election or publish such information in The Wall Street Journal or another
newspaper of general circulation in the City of New York or on the Company’s website. Upon any
such conversion following a valid Physical Settlement Election, the Company shall, subject to the
provisions of this Article 10, satisfy its Conversion Obligation by delivering to converting
Holders on the Conversion Settlement Date a number of shares of Common Stock (the “Settlement
Shares”) equal to the aggregate principal amount of Securities to be converted divided by $1,000
and multiplied by the Applicable Conversion Rate on the Conversion Date (which will include any
increases to reflect any Additional Shares as described under Section 10.01(b)(3) above); provided
that no fractional shares shall be issued, and in lieu thereof, the Company shall pay an amount in
cash as set forth in Section 10.02 above.



     Section
10.04 Adjustment of Applicable Conversion Rate. The Applicable Conversion Rate shall be adjusted,
without duplication, from time to time by the Company in accordance with this Section 10.04, except
that the Company will not make any adjustment if Holders of Securities are entitled to participate
on the relevant distribution or payment date, as a result of holding the Securities, in the
transactions described in Sections 10.04(b), (c) and (d) below without having to convert their
Securities (based on the Applicable Conversion Rate in effect immediately before the relevant
Ex-Dividend Date):



58









 





     (b) If the Company, at any time or from time to time while any of the Securities are
outstanding, issues shares of Common Stock as a dividend or distribution on shares of Common Stock,
or if the Company effects a share split or share combination, then the Applicable Conversion Rate
will be adjusted based on the following formula:








	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect immediately prior to the
Ex-Dividend Date of such dividend or distribution, or the effective date of such share
split or share combination, as applicable;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately on and after such
Ex-Dividend Date, or effective date of such share split or combination, as applicable;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately before such
Ex-Dividend Date or effective date, as applicable; and
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding immediately before such
Ex-Dividend Date or effective date, but after giving effect to such dividend,
distribution, share split or combination, as applicable.






     Such adjustment shall become effective immediately after the Ex-Dividend Date for such
dividend or distribution, or the effective date for such share split or share combination. If any
dividend or distribution of the type described in this Section 10.04(a) is declared but not so paid
or made, the Applicable Conversion Rate shall again be adjusted, as of the date that is the earlier
of (i) the public announcement of the non-payment of the dividend or distribution and (ii) the date
that the dividend or distribution was to be paid, to the Applicable Conversion Rate which would
then be in effect if such dividend or distribution had not been declared.



     (b) If the Company, at any time or from time to time while any of the Securities are
outstanding, distributes to all, or substantially all, holders of Common Stock any rights, warrants
or options entitling them for a period of not more than 60 calendar days from the date of issuance
of such rights, warrants or options to subscribe for or purchase shares of Common Stock at an
exercise price per share of Common Stock less than the average of the Closing Sales Prices of
Common Stock for the 10 consecutive Trading Day period ending on the Business Day immediately
preceding the



59









 







date of announcement of such issuance, the Applicable Conversion Rate shall be adjusted based
on the following formula:








	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately on and after such
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately before such
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	X

	 	=
	 	the total number of shares of Common Stock issuable pursuant to such
rights, warrants or options; and
	 
	 	 	 	 
	Y

	 	=
	 	the number of shares of Common Stock equal to the quotient of (A) the
aggregate price payable to exercise such rights, warrants or options divided by (B)
the average of the Closing Sale Prices of Common Stock for the 10 consecutive Trading
Day period ending on the Trading Day immediately preceding the date of announcement of
the distribution of such rights, warrants or options.






     To the extent such rights, warrants or options are not exercised or converted prior to the
expiration of the exercisability or convertability thereof, the Applicable Conversion Rate shall be
readjusted, as of such expiration date, to the Applicable Conversion Rate which would then be in
effect had the adjustments made upon the distribution of such rights, warrants or options been made
on the basis of the delivery of only the number of shares of Common Stock actually delivered. In
the event that such rights, warrants or options are not so distributed, the Conversion Rate shall
again be adjusted to be the Applicable Conversion Rate which would then be in effect if such
rights, warrants or options had not been distributed. In determining whether any rights, warrants
or options entitle the Holders to subscribe for or purchase, or exercise a conversion right for,
shares of Common Stock at less than the average of the Closing Sale Prices of Common Stock for the
10 consecutive Trading Day period ending on the Business Day immediately preceding the date of
announcement of such issuance, and in determining the aggregate exercise or conversion price
payable for such shares of Common Stock, there shall be taken into account any consideration
received for such rights, warrants or options and the value of such consideration, if other than
cash, shall be determined in good faith by the Board of Directors.



60









 





     (c) If the Company, at any time or from time to time while the Securities are outstanding,
distributes shares of any class of Capital Stock of the Company, evidences of indebtedness or other
assets or property of the Company to all, or substantially all, holders of its Common Stock,
excluding:




     (i) dividends or distributions referred to in Section 10.04(a);




     (ii) rights, warrants or options referred to in Section 10.04(b);




     (iii) dividends or distributions paid exclusively in cash; and




     (iv) Spin-Offs (as defined below) to which the provisions set forth below in this
Section 10.04(c) shall apply;



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








	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately on and after such
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Closing Sale Prices of the Common Stock over the 10
consecutive Trading Day period ending on the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
	 
	 	 	 	 
	FMV

	 	=


	 	the Fair Market Value (as determined in good faith by the Board of
Directors) of the shares of 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.






     Such adjustment shall become effective immediately prior to the opening of business on the day
following the Ex-Dividend Date for such distribution.



     Where there has been a payment of a dividend or other distribution to holders of Common Stock
of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a
Subsidiary or other business unit (a “Spin-Off”), the Applicable Conversion Rate in effect
immediately before the close of business on the 10th Trading Day immediately following and
including the effective date of the Spin-Off shall be increased based on the following formula:



61









 










	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect on the 10th Trading Day
immediately following, and including, the effective date of the Spin-Off;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately after the 10th Trading
Day immediately following, and including, the effective date of the Spin-Off;
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Closing Sale 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 Day period after, and including,
the effective date of the Spin-Off; and
	 
	 	 	 	 
	MP0

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






     An adjustment to the Applicable Conversion Rate made pursuant to the immediately preceding
paragraph will occur at the close of business on the 10th Trading Day from, and including, the
effective date of the Spin-Off; provided that in respect of any conversion within the 10 Trading
Days following the effective date of any Spin-Off, references within this Section 10.04(c) to “10
Trading Days” shall be deemed replaced with such lesser number of Trading Days as have elapsed
between the effective date of such Spin-Off and the Conversion Date in determining the Applicable
Conversion Rate.



     If any dividend or distribution described in this Section 10.04(c) is declared but not paid or
made, the Applicable Conversion Rate shall be readjusted, as of the date that is the earlier of (i)
the public announcement of the non-payment of the dividend or distribution and (ii) the date that
the dividend or distribution was to have been paid, in which case, the Applicable Conversion Rate
will be the Applicable Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.



     For the purposes of this Section 10.04(c), rights, warrants or options distributed by the
Company to all holders of Common Stock entitling them to subscribe for or purchase shares of the
Company’s capital stock (either initially or under certain circumstances), which rights, warrants
or options until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed
to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also
issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed
for purposes of this Section 10.04(c) (and no adjustment to the Conversion Rate under this Section
10.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon



62









 







such rights and warrants shall be deemed to have been distributed and an appropriate
adjustment (if any is required) to the Conversion Rate shall be made under this Section 10.04(c).
If any such right, warrant or option, including any such existing rights, warrants or options
distributed prior to the date of this Indenture, is subject to events, upon the occurrence of which
such rights, warrants or options become exercisable to purchase different securities, evidences of
indebtedness or other assets, then the date of the occurrence of any and each such event shall be
deemed to be the date of distribution and record date with respect to new rights, warrants or
options with such rights (and a termination or expiration of the existing rights, warrants or
options without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights, warrants or options or any Trigger Event or other
event (of the type described in the preceding sentence) with respect thereto that was counted for
purposes of calculating a distribution amount for which an adjustment to the Applicable Conversion
Rate under this Section 10.04(c) was made, (1) in the case of any such rights, warrants or options
which shall all have been redeemed or purchased without exercise by any Holders thereof, the
Applicable Conversion Rate shall be readjusted upon such final purchase to give effect to such
distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to
the per share redemption or purchase price received by a holder of Common Stock with respect to
such rights, warrants or options (assuming such holder had retained such rights, warrants or
options), made to all applicable holders of Common Stock as of the date of such redemption or
purchase, and (2) in the case of such rights, warrants or options which shall have expired or been
terminated without exercise by any holders thereof, the Applicable Conversion Rate shall be
readjusted as if such rights, warrants or options had not been issued.



     (d) If any cash dividend or other distribution is made to all, or substantially all, holders
of Common Stock, the Applicable Conversion Rate shall be adjusted based on the following formula:








	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately on or after the
Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the Closing Sale Price of a share of Common Stock on the Trading Day
immediately preceding the earlier of the Record Date and the day immediately preceding
the Ex-Dividend Date for such distribution; and
	 
	 	 	 	 
	C

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






63









 






     An adjustment to the Applicable Conversion Rate made pursuant to this Section 10.04(d) shall
become effective on the Ex-Dividend Date for such dividend or distribution. If any dividend or
distribution described in this Section 10.04(d) is declared but not so paid or made, the new
Applicable Conversion Rate shall be adjusted, as of the date that is the earlier of (i) the public
announcement of the non-payment of the dividend or distribution and (ii) the date that the dividend
or distribution was to be paid, to the Applicable Conversion Rate that would then be in effect if
such dividend or distribution had not been declared.



     (e) If the Company or any Subsidiary makes a payment in respect of a tender offer or exchange
offer for Common Stock, where the cash and value (which will be, except for the value of traded
securities, determined by the Board of Directors) of any other consideration included in the
payment per share of Common Stock exceeds the Closing Sale Price of 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 Applicable Conversion Rate shall be adjusted as of immediately after the 10th
Trading Day immediately following, and including, the date the tender or exchange offer expires
based on the following formula:








	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Applicable Conversion Rate in effect on the 10th day immediately
following, and including, the date such tender or exchange offer expires;
	 
	 	 	 	 
	CR’

	 	=
	 	the Applicable Conversion Rate in effect immediately after the 10th Trading
Day immediately following, and including, the date such tender or exchange offer
expires;
	 
	 	 	 	 
	AC

	 	=
	 	the aggregate value of all cash and any other consideration (as determined
by the Board of Directors) paid or payable for shares of Common Stock purchased in
such tender or exchange offer;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding on the Trading Day
immediately prior to the date such tender or exchange offer expires;
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding on the Trading Day
immediately after the date such tender or exchange offer expires (after giving effect
to the purchase or exchange of shares pursuant to such tender or exchange offer); and
	 
	 	 	 	 
	SP’

	 	=
	 	the average of the Closing Sale Prices of Common Stock over the 10
consecutive Trading Day period commencing on the Trading







64









 






Day next succeeding the date such tender or exchange offer expires.



     The adjustment to the Applicable Conversion Rate under this Section 10.04(e) shall occur on
the 10th Trading Day from, and including, the Trading Day next succeeding the date such tender or
exchange offer expires; provided that in respect of any conversion within the 10 Trading Days
immediately following, and including, the expiration date of any tender or exchange offer,
references within this Section 10.04(e) to “10 Trading Days” shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the expiration date of such tender or
exchange offer and the Conversion Date in determining the Applicable Conversion Rate.



     If the Company is obligated to purchase shares pursuant to any such tender or exchange offer,
but the Company is permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Applicable Conversion Rate shall again be adjusted to be the
Applicable Conversion Rate that would then be in effect if such tender or exchange had not been
made.



     (f) No adjustment to the Applicable Conversion Rate will be required unless the adjustment
would require an increase or decrease of at least 1% of the Applicable Conversion Rate. If the
adjustment is not made because the adjustment does not change the Applicable Conversion Rate by at
least 1%, then the adjustment that is not made will be carried forward and taken into account in
any future adjustments. In addition, the Company will make any carry forward adjustments not
otherwise effected upon required purchases of the Securities in connection with a Fundamental
Change, upon any conversion of the Securities, on every one year anniversary from the original
issue date and on the Record Date immediately prior to Stated Maturity of the Securities.
Adjustments to the Applicable Conversion Rate will be rounded to the nearest ten-thousandth, with
five one-hundred-thousandths rounded upward (e.g., 0.76545 would be rounded up to 0.7655).



     (g) The Company from time to time may, to the extent permitted by applicable law, increase the
Applicable Conversion Rate by any amount for a period of at least 20 days if the Board of Directors
shall have made a determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. Whenever the Applicable Conversion Rate is increased
pursuant to this Section 10.04(g) or Section 10.04(h) below, the Company shall mail to Holders of
record of the Securities a notice of the increase at least 15 days prior to the date the increased
Applicable Conversion Rate takes effect, and such notice shall state the increased Applicable
Conversion Rate and the period during which it will be in effect.



     (h) The Company may (but is not required to) make such increases in the Applicable Conversion
Rate, in addition to any adjustments required by Section 10.04(a), Section 10.04(b), Section
10.04(c), Section 10.04(d), Section 10.04(e) or Section 10.04(g), as the Board of Directors
considers to be advisable to avoid or diminish income tax to Holders resulting from any dividend or
distribution of Capital Stock issuable on



65









 




conversion of the Securities (or rights to acquire
shares) or from any event treated as such for income tax purposes.




     (i) Except as otherwise provided in this Indenture, all calculations under this Article 10
shall be made by the Company. No adjustment shall be made for the Company’s issuance of Common
Stock or securities convertible into or exchangeable for shares of Common Stock or rights to
purchase Common Stock or convertible or exchangeable securities, other than as provided in this
Section 10.04. The Company shall make such calculations in good faith and, absent manifest error,
such calculations shall be binding on the Holders.



     (j) Whenever the Applicable Conversion Rate is adjusted as herein provided, the Company shall
promptly file with the Trustee and any Conversion Agent an Officer’s Certificate setting forth the
Applicable Conversion Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Applicable Conversion Rate and may assume without inquiry that the last
Applicable 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 Applicable
Conversion Rate setting forth the adjusted Applicable Conversion Rate, a brief statement of the
facts requiring such adjustment and the date on which each adjustment becomes effective and shall
mail such notice of such adjustment of the Applicable Conversion Rate to each Securityholder at
such Holder’s last address appearing on the list of Securityholders provided for in Section 2.05,
within 20 days after execution thereof. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment.



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



     (l) Notwithstanding anything to the contrary in this Article 10, no adjustment to the
Applicable Conversion Rate shall be made:




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




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



66









 






     (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant,
right or exercisable, exchangeable or convertible security not
described in (ii) above and outstanding as of the date the Securities were first
issued;




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




     (v) for accrued and unpaid Interest, including Additional Amounts, if any; or




     (vi) for the avoidance of doubt, for the issuance of Common Stock by the Company
(other than to all or substantially all holders of Common Stock) or the payment of cash by
the Company upon conversion or repurchase of Securities.



     Section 10.05 Conversion Limitation. (a) Notwithstanding anything to the contrary in this Indenture,
upon conversion of any of the Securities, in no event shall the Company issue a number of shares of
Common Stock equal to or in excess of the Notes Share Cap with respect to each $1,000 principal
amount of such Securities, unless (i) the Company shall have obtained the approval of its
stockholders for the issuance of 20% or more of our outstanding common stock on the date of
original issuance of the Securities in accordance with the NASDAQ rules or (ii) the Company shall
have irrevocably made a valid Physical Settlement Election as set forth in Section 10.03(b). The
Company shall deliver cash and shares of Common Stock constituting the Settlement Amount for the
Securities being converted in accordance with Section 10.03(a), except that the Company shall not
issue, and the Settlement Amount will not include, for each $1,000 principal amount of Securities
converted shares of Common Stock equal to or in excess of the Notes Share Cap, unless clause (i) or
(ii) of the preceding sentence applies.



     (b) The Company shall not take any action (other than with respect to share dividends or
distributions, in either case, made in shares of Common Stock, share splits or share combinations
pursuant to Section 10.04(a)) that would result in an adjustment in the Applicable Conversion Rate
pursuant to Section 10.04 without complying with the NASDAQ’s stockholder approval rules, to the
extent applicable, if such adjustment would result in the number of shares of Common Stock
deliverable per $1,000 principal amount of Securities being equal to or greater than the Notes
Share Cap.



     (c) The restrictions contained in this Section 10.05 shall apply at any time when the
Securities are outstanding, regardless of whether the Company then has a class of securities listed
on the NASDAQ.



     Section 10.06 Effect of Reclassification, Consolidation, Merger or Sale. (a) If any of the following
events occur, namely (i) any reclassification of the outstanding shares of Common Stock (other than
a subdivision or combination to which Section 10.04(c) applies or a change in par value) as a
result of which holders of Common Stock shall be entitled to receive cash, securities or other
property (such property, the “Exchange Property”) with respect to or in exchange for such Common
Stock, (ii) any



67









 




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




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



     (c) The Conversion Obligation in respect of any Securities converted following the effective
date of any such transaction shall be computed in the same manner as set forth in Section 10.03(a)
except that (1) if the Securities become convertible into Exchange Property, the Daily VWAP of the
Common Stock shall be



68









 




deemed to equal the sum of (A) 100% of the value of any Exchange Property
consisting of cash received per share of Common Stock and (B) the Daily VWAP of any Exchange
Property received per share of Common Stock consisting of securities that are traded on a U.S.
national securities exchange, and (2) the Fair Market Value of any other Exchange Property received
per share, shall be determined by an independent nationally recognized investment bank selected by
the Company for this purpose. Settlement (in cash and/or shares) shall occur on the Conversion
Settlement Date, provided, that any amount of the Settlement Amount or Settlement Shares, as
applicable, to be delivered in shares of Common Stock shall be paid in Exchange Property rather
than shares of Common Stock. If the Exchange Property includes more than one kind of property, the
amount of Exchange Property of each kind to be delivered shall be in the proportion that the value
of the Exchange Property (as calculated pursuant to Section 10.03) of such kind bears to the value
of all such Exchange Property. If the foregoing calculations would require the Company to deliver
a fractional share or unit of Exchange Property to a Holder of Securities being converted, the
Company shall deliver cash in lieu of such fractional share or unit based on the value of the
Exchange Property.




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



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



     If this Section 10.06 applies to any event or occurrence, Section 10.04 shall not apply to
such event or occurrence.



     Section
10.07 Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be
made without charge to the converting Holder for any tax in respect of the issue thereof, except
for applicable withholding, if any. The Company shall not, however, be required to pay any tax or
duty which may be payable in respect of any transfer involved in the issue and delivery of stock in
any name other than that of the Holder or beneficial owner of any Securities converted, and the
Company shall not be required to issue or deliver any such stock certificate unless and until the
person or persons requesting the issue thereof shall have paid to the Company the amount of such
tax or shall have established to the satisfaction of the Company that such tax has been paid or
that none is due.



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



69









 





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



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



     (d) The Company covenants that, if any shares of Common Stock to be provided for the purpose
of conversion of Securities hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly issued upon conversion,
the Company shall, in accordance with the provisions of the Registration Rights Agreement, endeavor
to secure such registration or approval, as the case may be.



     Section
10.09 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time
be under any duty or responsibility to any Holder of Securities to determine the Applicable
Conversion Rate or whether any facts exist which may require any adjustment of the Applicable
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when
made, or with respect to the method employed, or herein or in any supplemental indenture provided
to be employed, in making the same. The Trustee and any other Conversion Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any shares of Common
Stock, or of any securities or property, which may at any time be issued or delivered upon the
conversion of any Security; and the Trustee and any other Conversion Agent make no representations
with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any
failure of the Company to issue, transfer or deliver any shares of Common Stock or stock
certificates or other securities or property or cash upon the surrender of any Security for the
purpose of conversion or to comply with any of the duties, responsibilities or covenants of the
Company contained in this Article 10. Without limiting the generality of the foregoing, neither
the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness
of any provisions contained in any supplemental indenture entered into pursuant to Section 10.06
relating either to the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders upon the conversion of their Securities after any event referred to in such
Section 10.06 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon the Officer’s Certificate (which the Company shall be obligated
to file with the Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

ARTICLE 11



Guarantee




     Section
11.01 Guarantee by the Guarantor. (a) The Guarantor hereby irrevocably and unconditionally
guarantees, as a primary obligor and not merely as a surety, to each Holder and to the Trustee and
its successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity,
by acceleration, by repurchase or otherwise, of all obligations of the Company under this Indenture
(including obligations to the Trustee) and the Securities, whether for payment of principal of,
Interest or Additional Amounts on, and any cash payment due on conversion of, in respect of the
Securities and all other monetary obligations of the Company under this Indenture and the
Securities and (ii) the full and punctual performance within applicable grace periods of all other
monetary obligations of the Company whether for fees, expenses, indemnification or otherwise under
this Indenture and the Securities (all the foregoing being hereinafter collectively called the
"Guaranteed Obligations”). The Guarantor further agrees that the Guaranteed Obligations may be
extended or renewed, in whole or in part, without notice or further assent from the Guarantor, and
that the Guarantor shall remain bound under this Article 11 notwithstanding any extension or
renewal of any Guaranteed Obligation.



     A Guarantee by the Guarantor shall be signed in the name and on behalf of the Guarantor by the
manual or facsimile signature of its President, any Vice President (whether or not designated by
number or numbers or word or words added before or after the title “Vice President”), its
Treasurer, its Secretary or any Assistant Secretary. A Guarantee bearing the manual signatures of
individuals who were at any time the proper officers of the Guarantor shall bind the Guarantor,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
execution and delivery of the Guarantee or did not hold such offices at the date of such Guarantee.



     (b) The Guarantor waives presentation to, demand of payment from and protest to the Company of
any of the Guaranteed Obligations and also waives notice of protest for nonpayment. The Guarantor
waives notice of any default under the Securities or the Guaranteed Obligations. The obligations
of the Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any right or remedy against the Company or any other
Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension
or renewal of any thereof; or (iii) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Securities or any other agreement.



     (c) The Guarantor hereby waives any right to which it may be entitled to have the assets of
the Company first be used and depleted as payment of the Company’s or the Guarantor’s obligations
hereunder prior to any amounts being claimed from or paid by the Guarantor hereunder. The
Guarantor hereby waives any right to which it may be entitled to require that the Company be sued
prior to an action being initiated against the Guarantor. The Guarantor further agrees that
guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a
guarantee of collection).



71









 





     (d) Except as expressly set forth in Section 11.02, the obligations of the Guarantor hereunder
shall not be subject to any reduction, limitation, impairment or termination for any reason,
including any claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason
of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of the Guarantor herein shall not
be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any
other agreement, by any waiver or modification of any thereof, by any default, failure or delay,
willful or otherwise, in the performance of the obligations, or by any other act or thing or
omission or delay to do any other act or thing which may or might in any manner or to any extent
vary the risk of the Guarantor or would otherwise operate as a discharge of the Guarantor as a
matter of law or equity.



     (e) Except as otherwise provided herein, the Guarantor agrees that its guarantee shall remain
in full force and effect until payment in full of all the Guaranteed Obligations. The Guarantor
further agrees that such guarantee shall continue to be effective or be reinstated, as the case may
be, if at any time payment, or any part thereof, of principal of or Interest on any Guaranteed
Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise. Upon the payment in full of the
Guaranteed Obligations when due at maturity, upon repurchase or otherwise, except as described
above, the Guarantor shall cease to be a guarantor hereunder.



     (f) In furtherance of the foregoing and not in limitation of any other right which any Holder
or the Trustee has at law or in equity against the Guarantor by virtue hereof, upon the failure of
the Company to pay the principal of or Interest or Additional Amounts on any Guaranteed Obligation
when and as the same shall become due, whether at maturity, by acceleration, by repurchase or
otherwise, or to perform or comply with any other Guaranteed Obligation, the Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be
paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid principal
amount of such Guaranteed Obligations, (ii) accrued and unpaid Interest or Additional Amounts on
such Guaranteed Obligations (but only to the extent not prohibited by law) and (iii) all other
monetary obligations of the Company to the Holders and the Trustee.



     (g) The Guarantor agrees that it shall not be entitled to any right of subrogation in relation
to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of
all Guaranteed Obligations. The Guarantor further agrees that, as between it, on the one hand, and
the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations
guaranteed hereby may be accelerated as provided in Article 6 for the purposes of the guarantee
provided in this Article 11, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event
of any declaration of acceleration of such Guaranteed Obligations as provided in



72









 







Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become
due and payable by the Guarantor for the purposes of this Section 11.01.



     (h) Upon request of the Trustee, the Guarantor shall execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.



     Section 11.02
Limitation on Liability. Any term or provision of this Indenture to the contrary
notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by
the Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering
this Indenture, as it relates to the Guarantor, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors
generally.



     Section 11.03
Successors and Assigns. This Article 11 shall be binding upon the Guarantor and its
successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee
and the Holders and, in the event of any transfer or assignment of rights by any Holder or the
Trustee, the rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or assignee, all subject
to the terms and conditions of this Indenture.



     Section 11.04
No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in
exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof,
nor shall a single or partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights, remedies or benefits
which either may have under this Article 11 at law, in equity, by statute or otherwise.



     Section 11.05
Modification. No modification, amendment or waiver of any provision of this Article 11, nor
the consent to any departure by the Guarantor therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Trustee, and then such waiver or consent shall be

[FORM OF REVERSE OF GLOBAL SECURITY]




2.75% Senior Convertible Notes Due 2010




     This Security is one of a duly authorized issue of 2.75% Senior Convertible Notes Due 2010
(the “Securities”) of Integra LifeSciences Holdings Corporation, a Delaware corporation (including
any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under
an Indenture, dated as of June 11, 2007 (the “Indenture”), among the Company, Integra LifeSciences
Corporation, a Delaware corporation (the “Guarantor”), and Wells Fargo Bank, N.A., as trustee (the
"Trustee”). The terms of the Security include those stated in the Indenture, those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), and those set
forth in this Security. This Security is subject to all such terms, and Holders are referred to
the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable
law, in the event of any inconsistency between the terms of this Security and the terms of the
Indenture, the terms of the Indenture shall control. Capitalized terms used but not defined herein
have the meanings assigned to them in the Indenture unless otherwise indicated.



1. Interest.




     The Securities shall bear Interest on the principal amount thereof at a rate of 2.75% per
year. The Company shall also pay Additional Amounts, if any, as set forth in the Indenture and the
Registration Rights Agreement.



     Interest shall be payable semi-annually in arrears on each Interest Payment Date to Holders at
the close of business on the preceding Interest Record Date. Interest shall be computed on the
basis of a 360-day year comprised of twelve 30 day months and will accrue from June 11, 2007 or
from the most recent date to which Interest has been paid or duly provided for.



     The Company shall pay Interest to the Securityholder of record on the Interest Record Date,
except that if a Securityholder elects to require the Company to repurchase Securities on a date
that is after an Interest Record Date but on or prior to the corresponding Interest Payment Date,
the Company shall pay accrued and unpaid Interest on the Securities being repurchased to, but not
including, the Fundamental Change Repurchase Date to the Securityholder of record on the
Fundamental Change Repurchase Date.



     If the principal amount of any Security, or any accrued and unpaid Interest or Additional
Amounts, if any, are not paid when due (whether upon acceleration pursuant to Section 6.02 of the
Indenture, upon the date set for payment of the Fundamental Change Repurchase Price pursuant to
Section 4 hereof, upon the Stated Maturity of the Securities, upon the Interest Payment Dates or
upon the Additional Amounts Payment Dates (as defined in the Registration Rights Agreement)), then
in each such case the overdue amount shall, to the extent permitted by law, bear cash interest at
the rate of



A-6









 




2.75% per annum, compounded semi-annually, which interest shall accrue from the date such
overdue amount was originally due to the date payment of such amount, including interest thereon,
has been made or duly provided for. All such interest shall be payable in cash on demand but if
not so demanded shall be paid quarterly to the Holders on the last day of each quarter.




2. Method of Payment.




     Except as provided below, the Company shall pay Interest, including Additional Amounts, if
any, on (i) Global Securities, to DTC in immediately available funds, (ii) any Certificated
Security having an aggregate principal amount of $2,000,000 or less, by check mailed to the Holder
of such Security and (iii) any Certificated Security having an aggregate principal amount of more
than $2,000,000, by wire transfer in immediately available funds if requested by the Holder of any
such Security as least five business days prior to the relevant Interest Payment Date.



     At Stated Maturity, the Company shall pay Interest on Certificated Securities at the Company’s
office or agency maintained for that purpose, which initially shall be the office or agency of the
Trustee located at 213 Court Street, Suite 703, Middletown, Connecticut 06457.



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



3. Indenture.




     The Securities are senior, unsecured obligations of the Company limited to $165,000,000
aggregate principal amount. The Indenture does not limit other indebtedness of the Company,
secured or unsecured.



4. Purchase By the Company at the Option of the Holder.




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



A-7









 





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



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



5. Conversion.




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



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



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



     The initial Applicable Conversion Rate is 15.0917 shares of Common Stock per $1,000 principal
amount (equal to an initial conversion price of approximately $66.2616 per share), subject to
adjustment in certain events described in the Indenture. The Applicable Conversion Rate shall not
be adjusted for any accrued and unpaid Interest or accrued and unpaid Additional Amounts, if any.
Upon conversion, no payment shall be made by the Company with respect to accrued and unpaid
Interest and accrued and unpaid Additional Amounts, if any. Instead, such amount shall be deemed
paid by the cash and shares of Common Stock, if any, delivered upon conversion of any Security. In
addition, no payment or adjustment shall be made in respect of dividends on the Common Stock,
except as set forth in the Indenture.



     In addition, following certain corporate transactions as set forth in Section 10.01(b) of the
Indenture that constitute a Fundamental Change, a Holder who elects to convert its Securities in
connection with such corporate transaction shall be entitled to receive Additional Shares of Common
Stock upon conversion, subject to the terms and conditions set forth in Section 10.01(b)(3) of the
Indenture.



A-8









 





     Notwithstanding anything to the contrary in this Security or the Indenture, the total number
of shares of Common Stock issuable upon conversion of this Security is subject to the limitation
set forth in Section 10.05 of the Indenture.



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



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



     If the Company engages in any reclassification of the Common Stock (other than a subdivision
or combination of its outstanding Common Stock, or a change in par value, or from par value to no
par value, or from no par value to par value) or is party to a consolidation, merger, binding share
exchange or transfer of all or substantially all of its assets, and as a result of any such event
the Holders of Common Stock would be entitled to receive Exchange Property for their Common Stock,
upon conversion of the Securities after the effective date of such event, the Conversion Obligation
and the Settlement Amount shall be based on the Applicable Conversion Rate and the Exchange
Property, in each case in accordance with the Indenture. If the transaction also constitutes a
Fundamental Change that would lead to the issuance of Additional Shares as set forth in Section
10.01(b)(3) of the Indenture, if a Holder elects to convert all or a portion of its Securities,
such Holder shall receive Additional Shares upon conversion pursuant to Section 10.01(b)(3) of the
Indenture, subject to the terms and conditions set forth in such Section.



6. Paying Agent, Conversion Agent and Registrar.




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



7. Denominations; Transfer; Exchange.




     The Securities are in fully registered form, without coupons, in denominations of $1,000
principal amount and integral multiples of $1,000. A Holder may transfer or exchange Securities in
accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees required by law or
permitted by the Indenture. The Registrar need not transfer or exchange any Securities in respect
of which a Fundamental



A-9









 







Change Repurchase Notice has been given and not withdrawn (except, in the case of a Security
to be purchased in part, the portion of the Security not to be purchased).



8. Persons Deemed Owners.




     Except as otherwise provided in the Indenture, the registered Holder of this Security will be
treated as the owner of this Security for all purposes.



9. Unclaimed Money or Securities.




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



10. Amendment; Waiver.




     Subject to certain exceptions set forth in the Indenture, (i) the Indenture, the Securities
and the Guarantee may be amended with the written consent of the Holders of at least a majority in
aggregate principal amount of the outstanding Securities and (ii) certain Events of Defaults may be
waived with the written consent of the Holders of a majority in aggregate principal amount of the
outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the
consent of any Securityholder, the Company, the Guarantor and the Trustee may amend the Indenture,
the Securities or the Guarantee as provided in Section 9.01 of the Indenture.



11. Defaults and Remedies.




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



12. Trustee Dealings with the Company.




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



13. Calculations in Respect of Securities.




     Except as otherwise provided in the Indenture, the Company or its agents shall be responsible
for making all calculations called for under the Securities including, but not



A-10









 







limited to, determination of the market prices for the Securities and of the Common Stock and
the Additional Amounts, if any, accrued on the Securities. Any calculations made in good faith and
without manifest error shall be final and binding on Holders of the Securities. The Company or its
agents shall be required to deliver to the Trustee a schedule of its calculations and the Trustee
shall be entitled to conclusively rely upon the accuracy of such calculations without independent
verification.



14. No Recourse Against Others.




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



15. Authentication.




     This Security shall not be valid until an authorized signatory of the Trustee manually signs
the Trustee’s Certificate of Authentication on the other side of this Security.



16. Abbreviations.




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



17. Governing Law.

EFFECT TO THE CONFLICT OF LAWS RULES THEREOF.
