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 14.2. 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

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. 

 
 

ARTICLE II    
    
    THE SECURITIES    
    

        Section 2.1.    Form and Dating.    

        The
Securities and the Trustee's certificate of authentication shall be substantially in the form of Exhibit A attached hereto, which is a part of this Indenture. The Securities
may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form acceptable to the
Company). The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. 

        (a)    Restricted Global Securities.    All of the Securities are being offered and sold to QIBs in reliance on
Rule 144A and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the
Depositary and registered in the name of DTC or the nominee thereof, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the
Restricted
Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. 

        (b)    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 initially represent the aggregate amount of outstanding Securities stated thereon, but that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, repurchases and conversions of such Securities. 

        Any
adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall
be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the records of the Trustee and the Depositary. 

        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 contained herein shall (A) 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 

8

 

furnished
by the Depositary or such nominee, as the case may be, or (B) 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. 

        (c)    Certificated Securities.    Certificated Securities will be issued only under the limited circumstances
provided in Section 2.12(a)(i). 

        Section 2.2.    Execution and Authentication.    

        The
Securities shall be executed on behalf of the Company by any Officer. The signature of the Officer on the Securities may be manual or facsimile. 

        A
Security bearing the manual or facsimile signature of an individual who was at the time of the execution of the Security an Officer shall bind the Company, notwithstanding that such
individual has ceased to hold such office(s) prior to the authentication and delivery of such Securities or did not hold such office(s) 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 $575,000,000 upon one or more Company Orders without any further
action by the Company (other than as contemplated in Section 14.4 and Section 14.5). At any time and from time to time after the execution and delivery of this Indenture, the Company may
deliver Securities executed by the Company to the Trustee for authentication. Except as otherwise provided in this Article Two, the Trustee shall thereupon authenticate and make available for delivery
such Securities to or upon a Company Order. The aggregate principal amount of the Securities due at the Stated Maturity thereof outstanding at any time may not exceed the amount set forth in the
foregoing sentence except as provided in Section 2.7. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall receive and shall be fully protected in relying upon: 

        (a)   a
copy of the Board Resolution in or pursuant to which the terms and form of the Securities were established, the issuance and sale of the Securities was authorized,
this Indenture was authorized and specified Officers were authorized to establish the form and determine the terms of the Securities and the form of this Indenture, to execute the Securities and this
Indenture on behalf of the Company and to take any other necessary actions relating thereto and evidence of any actions taken by authorized Officers pursuant to that Board Resolution, each certified
by the Secretary or an Assistant Secretary of the Company to have been duly adopted by the Board of Directors or taken by any authorized Officer and to be in full force and effect as of the date of
such certificate; 

        (b)   an
Officers' Certificate delivered in accordance with Sections 14.4 and 14.5; and 

        (c)   an
Opinion of Counsel reasonably satisfactory to the Trustee. 

        The
Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An
authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. 

9

 

        The
Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiple of $1,000. 

        Section 2.3.    Registrar, Paying Agent, Conversion Agent and Bid Solicitation Agent.    

        The
Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange
("Registrar"), an office or agency where Securities may be presented for redemption, repurchase or
payment ("Paying Agent"), an office or agency where Securities may be presented for conversion
("Conversion Agent") and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be
served. The Company shall also appoint a bid solicitation agent ("Bid Solicitation Agent") to act as set forth in Section 1 of the Securities.
Pursuant to Section 6.5, the Company will at all times maintain a Registrar, Paying Agent, Conversion Agent, and Bid Solicitation Agent and an office or agency where notices and demands to or
upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, New York City. The Registrar shall keep a register of the Securities and of their transfer
and exchange. 

        The
Company may have one or more co-registrars, one or more additional paying agents, one or more additional conversion agents and one or more additional Bid Solicitation
Agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 6.5. The term Conversion Agent includes any additional conversion agent, including
any named pursuant to Section 6.5. 

        The
Company shall enter into an appropriate limited agency agreement with any Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or co-registrar (in each case,
if such Person is a Person other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and
address of any such agent. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent, the Trustee shall act as such and shall be entitled to appropriate
compensation therefor pursuant to Section 9.7. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar.
None of the Company or any Subsidiary or any Affiliate of any of them may act as Bid Solicitation Agent. 

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

        Section 2.4.    Paying Agent to Hold Cash and Securities in Trust.    

        Except
as otherwise provided herein, prior to 10:00 a.m., New York City time, on each due date of payments in respect of any Security, the Company shall deposit with the Paying
Agent Cash (in immediately available funds if deposited on the due date) or number of shares of Common Stock and/or Applicable 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 Cash, Common Stock and
Applicable Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company,
a Subsidiary or an Affiliate of any of them acts as Paying Agent, it shall segregate the money, Common Stock and Applicable 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 Cash, Common Stock and Applicable Stock held by it to the Trustee, and to account for any funds, Common Stock or Applicable
Stock disbursed by it, and the Trustee may at any time during the continuance of any such payment default referred to above, upon the written request to the Paying Agent, require such Paying Agent to
forthwith pay to the Trustee all Cash, Common Stock and Applicable Stock so held in trust. Upon 

10

 

doing
so, the Paying Agent shall have no further liability for the Cash, Common Stock or Applicable Stock. 

        Section 2.5.    Securityholder Lists.    

        The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall cause to be furnished to the Trustee on or before each semiannual interest payment date and at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 

        Section 2.6.    Transfer and Exchange.    

        (a)   Subject
to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to the Registrar with a request to
register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange
as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A attached hereto and in form satisfactory to the Registrar and each duly
executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at
an office or agency maintained for such purpose pursuant to Section 2.3, the Company shall execute, and the Trustee shall authenticate Securities of a like aggregate principal amount at the
Registrar's request. Any transfer or exchange shall be without charge, except that the Company or the Registrar 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. 

        Neither
the Company, the Registrar nor the Trustee shall be required to exchange or register a transfer of (i) any Securities selected for redemption (except, in the case of
Securities to be redeemed in part, the portion thereof not to be redeemed), (ii) any Securities in respect of which a Repurchase Notice or 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 repurchased in part, the portion thereof not to be repurchased) or
(iii) any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 

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

        (b)   Any
Registrar appointed pursuant to Section 2.3 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. 

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

        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 other beneficial owners of interests in any Global Security)
other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to 

11

 

do
so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

        Section 2.7.    Replacement Securities.    

        If
(a) any mutilated Security is surrendered to the Company, the Registrar or the Trustee, or (b) the Company, the Registrar and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the Registrar and the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Company, the Registrar or the Trustee that such Security has been acquired by a bona fide or protected 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 redeemed by the Company pursuant to Article III
or repurchased by the Company pursuant to Article IV or V, the Company in its discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be. 

        Upon
the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Registrar) connected therewith. 

        Every
new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation
of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Securities duly issued hereunder. 

        The
provisions of this Section 2.7 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 2.8.    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 paid, redeemed or repurchased pursuant to
Section 2.7, those delivered to it for cancellation and those described in this Section 2.8 as not outstanding. 

        A
Security does not cease to be outstanding because the Company or an Affiliate thereof 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. 

        If
a Security is replaced pursuant to Section 2.7, the replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide or protected purchaser unaware that such Security has been replaced. 

12

 

        If
the Paying Agent holds, in accordance with the terms of this Indenture, prior to 10:00 a.m., New York City time, on the Stated Maturity or a Redemption Date or on the Business
Day immediately following a Repurchase Date or a Fundamental Change Repurchase Date, as the case may be, Cash or securities, if permitted hereunder, sufficient to pay Securities payable, then
immediately after such Stated Maturity, Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, 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 XII, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and
interest (including Contingent Interest, if any) and Additional Amounts, if any, on such Security shall cease to accrue. 

        Section 2.9.    Temporary Securities.    

        Pending
the preparation of definitive 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 definitive 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 will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.3,
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 definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities. 

        Section 2.10.    Cancellation.    

        All
Securities surrendered for payment, repurchase by the Company pursuant to Articles IV or V, conversion, redemption 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 or that any Holder has converted pursuant to Article XII. 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 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 (whether in Cash, Common Stock or Applicable Stock) of principal of, Redemption Price, Repurchase Price or Fundamental
Change Repurchase Price, and interest and Additional Amounts, if any, on, the Security, for the purpose of receiving Cash or Common Stock upon conversion and for all other purposes whatsoever, whether
or not such Security is overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 

13

 

        Section 2.12.    Additional Transfer and Exchange Requirements.    

        (a)    Transfer and Exchange of Global Securities.    

        (i)    Certificated
Securities shall be issued in exchange for interests in the Global Securities only if (x) the Depositary notifies the Company that it is unwilling or
unable to continue as Depositary for the Global Securities or if it at any time ceases to be a "clearing agency" registered under the Exchange Act, if so required by applicable law or regulation and a
successor Depositary is not appointed by the Company within 90 days, (y) the Company decides to discontinue use of the system of book-entry transfer through DTC (or any
successor depositary) or (z) an Event of Default has occurred and is continuing. In either case, the Company shall execute, and the Trustee shall, upon receipt of a Company Order (which the
Company agrees to deliver promptly), authenticate and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor.
Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in Restricted Global Securities, and only Unrestricted Certificated Securities shall be issued in exchange
for beneficial interests in Unrestricted Global Securities. Certificated Securities issued in exchange for beneficial interests in Global Securities shall be registered in such names and shall be in
such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be
delivered such Certificated Securities to the Persons in whose name such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. 

        (ii)   Notwithstanding
any other provisions of this Indenture other than the provisions set forth in Section 2.12(a)(i), a Global Security may not be transferred except
as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. 

        (b)    Transfer and Exchange of Certificated Securities.    In the event that Certificated Securities are issued in
exchange for beneficial interests in Global Securities in accordance with Section 2.12(a)(i), and, on or after such event, Certificated Securities are presented by a Holder to the Registrar
with a request: 

        (x)   to
register the transfer of the Certificated Securities to a person who will take delivery thereof in the form of Certificated Securities only; or 

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

such
Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or
surrendered for register of transfer or exchange: 

        (i)    shall
be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6; and 

        (ii)   in
the case of a Restricted Certificated Security, such request shall be accompanied by the following additional information and documents, as applicable: 

        (A)  if
such Restricted Certificated Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such
Restricted Certificated Security is being transferred to the Company or a Subsidiary of the Company, a certification to that effect from such Holder (in substantially the form set forth in the
Transfer Certificate); 

14

 

        (B)  if
such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in accordance with Rule 144A or pursuant to an
effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or 

        (C)  if
such Restricted Certificated Security is being transferred pursuant to an exemption from the registration requirements of the Securities Act in accordance with
Rule 144 pursuant to and in compliance with an exemption from the registration requirements under the Securities Act, a certification to that effect from the Holder (in substantially the form
set forth in the Transfer
Certificate) and if the Company or the Registrar so requests, a customary Opinion of Counsel, certificates and other information reasonably acceptable to the Company and the Registrar to the effect
that such transfer does not require registration under the Securities Act. 

        (c)    Transfer of a Beneficial Interests in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global
Security.    Any person having a beneficial interest in a Restricted Global Security may upon request, subject to the Applicable Procedures, transfer such beneficial
interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written instructions, or such other form of
instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional
information and documents in such form as is customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Security
(all of which may be submitted by facsimile or electronically): 

        (i)    if
such beneficial interest is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from the Holder
(in substantially the form set forth in the Transfer Certificate); or 

        (ii)   if
such beneficial interest is being transferred pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144, a
certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Trustee so requests, a customary Opinion of Counsel,
certificates and other information reasonably acceptable to the Company and the Registrar to the effect that such transfer does not require registration under the Securities Act, 

the
Registrar shall reduce or cause to be reduced the aggregate principal amount of the Restricted Global Security by the appropriate principal amount and shall increase or cause to be increased the
aggregate principal amount of the Unrestricted Global Security by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted
Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver an
Unrestricted Global Security. 

        (d)    Transfer of a Beneficial Interest in an Unrestricted Global Security for a Beneficial Interest in a Restricted Global
Security.    Any person having a beneficial interest in an Unrestricted Global Security may upon request, subject to the Applicable Procedures, transfer such
beneficial interest to a person who is required or permitted to take delivery thereof in the form of a Restricted Global Security (it being understood that only QIBs may own beneficial interests in
Restricted Global Securities). Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the Depository or its nominee on behalf
of any person having a beneficial interest in an Unrestricted Global Security and the following additional information and documents in such form as is customary for the Depositary, from the
Depositary or its nominee on behalf of the person having such beneficial interest in the Unrestricted Global Security (all of which may be submitted by facsimile

or
electronically): a certification from the Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such beneficial interest is being transferred to a person that
the transferor reasonably believes is a QIB in accordance with Rule 144A. The Registrar shall reduce or cause to be reduced the aggregate principal amount of the Unrestricted Global Security by
the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Restricted Global Security by a like principal amount. Such transfer shall otherwise
be effected in accordance with the Applicable Procedures. If no Restricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which
the Company agrees to deliver promptly), authenticate and deliver a Restricted Global Security. 

        (e)    Transfers of Certificated Securities for Beneficial Interest in Global Securities.    In the event that
Certificated Securities are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 2.12(a)(i) which required such
exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities or interests in Global Securities by complying
with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if Certificated Securities are
presented by a Holder to a Registrar with a request: 

        (x)   to
register the transfer of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial interest in a Global Security, which
request shall specify whether such Global Security will be a Restricted Global Security or an Unrestricted Global Security, or 

        (y)   to
exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which beneficial interests will be owned by the
Holder transferring such Certificated Securities (provided that in the case of such an exchange, Restricted Certificated Securities may be exchanged only for Restricted Global Securities and
Unrestricted Certificated Securities may be exchanged only for Unrestricted Global Securities), the Registrar shall register the transfer or make the exchange as requested by canceling such
Certificated Security and causing the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security is then outstanding, the Company shall
issue and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly) authenticate and deliver a new Global Security; 

provided, however, that the Certificated Securities presented or surrendered for registration of transfer or exchange: 

        (1)   shall
be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to Section 2.6(a); 

        (2)   in
the case of a Restricted Certificated Security to be transferred for a beneficial interest in an Unrestricted Global Security, such request shall be accompanied by
the following additional information and documents, as applicable: 

        (i)    if
such Restricted Certificated Security is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect
from such Holder (in substantially the form set forth in the Transfer Certificate); or 

        (ii)   if
such Restricted Certificated Security is being transferred pursuant to an exemption from the registration requirements of the Securities Act in accordance with
Rule 144, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Registrar so requests, a customary Opinion
of Counsel, certificates and other information reasonably acceptable to the Company and the 

16

 

Trustee
to the effect that such transfer does not require registration under of the Securities Act; 

        (3)   in
the case of a Restricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global Security, such request shall be
accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Restricted Certificated Security is being transferred to a
person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A; 

        (4)   in
the case of an Unrestricted Certificated Security to be transferred or exchanged for a beneficial interest in an Unrestricted Global Security, such request need not
be accompanied by any additional information or documents; and 

        (5)   in
the case of an Unrestricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global Security, such request shall be
accompanied by a certification from such
Holder (in substantially, the form set forth in the Transfer Certificate) to the effect that such Unrestricted Certificated Security is being transferred to a person the Holder reasonably believes is
a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A. 

        (f)    Legends.    

        (1)   Except
as permitted by the following paragraphs (2), (3) and (4), each Global Security and Certificated Security (and all Securities issued in exchange therefor
or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A attached hereto (each a  "Transfer Restricted Security"),
for so long as it is required by this Indenture to bear such legend. Each Transfer Restricted Security shall have
attached thereto a certificate (a "Transfer Certificate") in substantially the form called for by footnote 5 to Exhibit A attached hereto. 

        (2)   Upon
any sale or transfer of a Transfer Restricted Security (x) after the expiration of the holding period applicable to sales of the Securities under
Rule 144(k) of the Securities Act, (y) pursuant to Rule 144 or (z) pursuant to an effective registration statement under the Securities Act: 

        (i)    in
the case of any Restricted Certificated Security, any Registrar shall permit the Holder thereof to exchange such Restricted Certificated Security for an Unrestricted
Certificated Security, or (under the circumstances described in Section 2.12(e)) to transfer such Restricted Certificated Security to a transferee who shall take such Security in the form of a
beneficial interest in an Unrestricted Global Security, and in each case shall rescind any restriction on the transfer of such Security; provided,
however, that the Holder of such Restricted Certificated Security shall, in connection with such exchange or transfer, comply with the other applicable provisions of this
Section 2.12; and 

        (ii)   in
the case of any beneficial interest in a Restricted Global Security, the Trustee shall permit the beneficial owner thereof to transfer such beneficial interest to a
transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Security and shall rescind any restriction on transfer of such beneficial interest;  provided,
however, that such Unrestricted Global Security shall continue to be subject to the provisions
of Section 2.12(a)(ii); and provided, further, that the owner of such beneficial interest shall,
in connection with such transfer, comply with the other applicable provisions of this Section 2.12. 

        (3)   Upon
the exchange, registration of transfer or replacement of Securities not bearing the legend described in paragraph (1) above, the Company shall execute, and
the Trustee shall 

17

 

authenticate
and deliver, Securities that do not bear such legend and that do not have a Transfer Certificate attached thereto. 

        (4)   After
the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company may with the consent of the Holder of a Restricted Global
Security or a Restricted Certificated Security, remove any restriction of transfer on such Security, and the Company shall execute, and the Trustee shall authenticate and deliver, Securities that do
not bear such legend and that do not have a Transfer Certificate attached thereto. 

        (5)   Until
the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act or a transfer pursuant to Rule 144
or pursuant to an effective registration statement under the Securities Act, the shares of Common Stock issued upon conversion of the Securities shall bear the legend in substantially the form called
for by Exhibit B attached hereto. 

        (g)    Transfers to the Company.    Nothing contained in this Indenture or in the Securities shall prohibit the sale
or other transfer of any Securities (including beneficial interests in Global Securities) to the Company or any of its Subsidiaries, which Securities shall thereupon be cancelled in accordance with
Section 2.10. 

        Section 2.13.    CUSIP Numbers.    

        The
Company may issue the Securities with one or more "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Holders; provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers. 

 
 

ARTICLE III    
    
    REDEMPTION    
    

        Section 3.1.    The Company's Right to Redeem; Notice to Trustee.    

        Prior
to April 15, 2008, the Securities will not be redeemable at the Company's option. Beginning on April 15, 2008, the Company, at its option, may redeem the Securities
in accordance with this Article III for Cash at any time as a whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of Securities to be redeemed plus
any accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, on those Securities to, but not including, the Redemption Date (the
"Redemption Price"). 

        In
the event that the Company elects to redeem the Securities on a date that is on or after any Regular Record Date but before the corresponding Interest Payment Date, the Company shall
be required to pay any accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, to the same Holder to whom the Company pays the principal of such Security
regardless of whether such Holder was the registered Holder on the Regular Record Date immediately preceding such Redemption Date. 

        If
the Company elects to redeem Securities, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Securities to be redeemed and the Redemption Price. The
Company shall give this notice to the Trustee by a Company Order at least 40 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee). 

18

 

        Section 3.2.    Selection of Securities to Be Redeemed.    

        If
fewer than all of the outstanding Securities are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to be redeemed by
lot or on a pro rata basis. The Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.1 from outstanding Securities not previously
called for redemption. 

        Securities
and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of the Securities to be
redeemed. 

        Securities
and portions of Securities that are to be redeemed are convertible by the Holder until 5:00 p.m., New York City time, on the second Business Day immediately preceding
the Redemption Date. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the
converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which
have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 

        Section 3.3.    Notice of Redemption.    

        At
least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of
Securities to be redeemed. 

        The
notice of redemption shall identify the Securities to be redeemed and shall state: 

        (a)   the
Redemption Date; 

        (b)   the
Redemption Price; 

        (c)   the
Conversion Price; 

        (d)   the
name and address of the Paying Agent and Conversion Agent; 

        (e)   that
Securities called for redemption may be converted at any time prior to 5:00 p.m., New York City time, on the second Business Day preceding the Redemption
Date; 

        (f)    that
Holders who want to convert their Securities must satisfy the requirements set forth in Article XII; 

        (g)   that
Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 

        (h)   in
the case of any Security redeemed in part, that the Holder of such Security will receive a new Security or Securities, of authorized denominations for the principal
amount thereof remaining unredeemed; 

        (i)    if
fewer than all of the outstanding Securities are to be redeemed, the certificate numbers, if any, and principal amounts of the particular Securities to be redeemed; 

19

  

        (j)    that,
unless the Company defaults in making payment of such Redemption Price, interest and Additional Amounts, if any, on Securities called for redemption will cease to
accrue on and after the Redemption Date; 

        (k)   the
CUSIP number(s) of the Securities; and 

        (l)    any
other information the Company wants to present. 

        At
the Company's request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense; provided,
however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice
of redemption must be given to Holders in accordance with this Section 3.3; provided, further, that the text of the notice of redemption shall be
prepared by the Company. 

        Section 3.4.    Effect of Notice of Redemption.    

        Once
notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Securities which are converted
in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price. 

        Section 3.5.    Deposit of Redemption Price.    

        Prior
to 10:00 a.m., New York City time, on the applicable Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of
any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of Cash (in immediately available funds if deposited on the Redemption Date)
sufficient to pay the aggregate Redemption Price of all Securities or portions thereof which are to be redeemed as of such Redemption Date other than Securities or portions of Securities called for
redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. 

        If
the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, Cash sufficient to pay the Redemption Price
of any Securities for which notice of redemption is given, then, on such Redemption Date, such Securities will cease to be outstanding and interest (including Contingent Interest, if any) and
Additional Amounts, if any, on such Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate
(other than the right to receive the Redemption Price upon delivery of such Securities). 

        Section 3.6.    Securities Redeemed in Part.    

        Any
Certificated Security which is to be redeemed only in part shall be surrendered at the office of the Paying Agent and the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to the unredeemed
portion of the Security surrendered. 

        Section 3.7.    Repayment to the Company.    

        To
the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Securities or portions thereof which
the Company is redeeming as of the Redemption Date, then, promptly after the Redemption Date, the Paying Agent shall return any such excess to the Company.

ARTICLE IV    
    
    REPURCHASE OF SECURITIES
  AT THE OPTION OF HOLDERS
  ON SPECIFIC DATES    
    

        Section 4.1.    Optional Put.    

        (a)   Securities
shall be repurchased by the Company, at the option of the Holder thereof, on April 15, 2008, April 15, 2013 and April 15, 2018 (each, a  "Repurchase Date"), at a repurchase price equal to
100% of the principal amount of those Securities plus accrued and unpaid interest (including
Contingent Interest, if any) and Additional Amounts, if any, to, but not including, such Repurchase Date (the "Repurchase Price"), subject to
satisfaction by or on behalf of the Holder of the requirements set forth in Section 4.1(c). 

        (b)   No
later than 20 Business Days prior to each Repurchase Date, the Company shall mail a written notice of the repurchase right by first class mail to the Trustee and to
each Holder (and to beneficial owners as required by applicable law). The notice shall include a form of Repurchase Notice to be completed by the Holder and shall briefly state, as applicable: 

        (i)    the
date by which the Repurchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the repurchase right; 

        (ii)   the
Repurchase Date; 

        (iii)  the
Repurchase Price; 

        (iv)  whether
the Repurchase Price will be paid in Cash or, if permitted hereunder, in shares of Common Stock, or a combination thereof and, in the case of a combination, the
percentage of each; 

        (v)   if
the Company elects to pay the Repurchase Price in shares of Common Stock or a combination of Cash and shares of Common Stock, that the number of shares of Common
Stock each Holder will receive will equal the portion of the Repurchase Price to be paid in shares of Common Stock divided by the Market Price of one share of Common Stock; 

        (vi)  if
the Company elects to pay the Repurchase Price in shares of Common Stock or a combination of Cash and shares of Common Stock, the method of calculating the Market
Price of the shares of Common Stock; 

        (vii) that
because the Market Price of one share of Common Stock will be determined prior to the Repurchase Date, Holders of the Securities will bear the market risk that
the shares of Common Stock
to be received will decline in value between the date such Market Price is determined and the Repurchase Date; 

        (viii) the
name and address of the Paying Agent and the Conversion Agent; 

        (ix)  the
Conversion Rate and any adjustments thereto; 

        (x)   that
the Securities as to which a Repurchase Notice has been given may be converted if they are otherwise convertible pursuant to Article XII only if the
Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 

        (xi)  that
the Securities must be surrendered to the Paying Agent to collect payment; 

        (xii) that
the Repurchase Price for any Security as to which a Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the
Repurchase Date and the time of surrender of such Security; 

21

 

        (xiii) the
procedures the Holder must follow to exercise its put right under this Section 4.1; 

        (xiv) the
conversion rights, if any, of the Securities; 

        (xv) the
procedures for withdrawing a Repurchase Notice; 

        (xvi) that,
unless the Company defaults in making payment of such Repurchase Price, interest (including Contingent Interest, if any) and Additional Amounts, if any, on
Securities surrendered for repurchase by the Company will cease to accrue on and after the Repurchase Date; and 

        (xvii) the
CUSIP number(s) of the Securities. 

        At
the Company's request, the Trustee shall give the notice of repurchase right in the Company's name and at the Company's expense; provided,
however, that the Company makes such request at least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice
of repurchase right must be given to the Holder in accordance with this Section 4.1(b); provided, further, that the text of the notice of
repurchase right shall be prepared by the Company. 

        (c)   A
Holder may exercise its right specified in Section 4.1(a) upon delivery of a written notice of repurchase (a "Repurchase
Notice") to the Paying Agent at any time during the period beginning at 9:00 a.m., New York City time, on the date that is 20 Business Days immediately preceding the
relevant Repurchase Date until 5:00 p.m., New York City time, on the Business Day immediately preceding such Repurchase Date, stating: 

        (i)    the
certificate number of the Security which the Holder will deliver to be repurchased or the appropriate Depositary procedures if Certificated Securities have not been
issued; 

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

        (iii)  that
such Security shall be repurchased by the Company as of the Repurchase Date pursuant to the terms and conditions specified in the Securities and in this
Indenture; and 

        (iv)  in
the event the Company elects, pursuant to Section 4.2(b), to pay the Repurchase Price, in whole or in part, in shares of Common Stock but such portion of the
Repurchase Price shall ultimately be paid to such Holder entirely in Cash because any of the conditions to payment of the Repurchase Price in shares of Common Stock is not satisfied prior to
5:00 p.m., New York City time, on the Business Day immediately preceding the relevant Repurchase Date, as set forth in Section 4.2(b), whether such Holder elects to (A) withdraw
such Repurchase Notice as to some or all of the Securities to which such Repurchase Notice relates (stating the principal amount and certificate numbers, if any or the appropriate Depositary
procedures, if applicable, of the Securities as to which such withdrawal shall relate), or (B) receive Cash in respect of the entire Repurchase Price for all Securities (or portions thereof) to
which such Repurchase Notice relates. 

        The
delivery of such Security to the Paying Agent with, or at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at the offices of the Paying
Agent shall be a condition to the receipt by the Holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid
pursuant to this Section 4.1 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice. 

        If
a Holder, in such Holder's Repurchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of Section 4.3, fails to indicate such
Holder's choice with respect to the election set forth in Section 4.1(c)(iv), such Holder shall be deemed to have elected to receive 

22

 

Cash
in respect of the entire Repurchase Price for all Securities subject to such Repurchase Notice in the circumstances set forth in such Section 4.1(c)(iv). 

        The
Company shall repurchase from the Holder thereof, pursuant to this Section 4.1, a portion of a Security, so long as 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 4.1 shall be consummated by the delivery of the consideration to be received by the Holder
promptly following the later of the Repurchase Date and the time of delivery of the Security. 

        Notwithstanding
anything contained herein to the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 4.1(c) shall have the right
to withdraw such Repurchase Notice at any applicable time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase Date by delivery of a written notice
of withdrawal to the Paying Agent in accordance with Section 4.3. 

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

        Section 4.2.    The Company's Right to Elect Manner of Payment of Repurchase Price.    

        (a)   If
the Securities are to be repurchased on April 15, 2008 pursuant to Section 4.1(a), the Repurchase Price must be paid in Cash. If the Securities to be
repurchased on April 15, 2013 or April 15, 2018, pursuant to Section 4.1(a), the Repurchase Price may be paid for at the election of the Company, in Cash or shares of Common
Stock, or in any combination of Cash and shares of Common Stock, subject to the conditions set forth in Section 4.2(b). The Company shall designate, in the notice of repurchase right delivered
pursuant to Section 4.1(b), whether the Company will repurchase the Securities for Cash or, if permitted hereunder, shares of Common Stock, or, if a combination thereof, the percentages of the
Repurchase Price in respect of which it will pay in Cash or shares of Common Stock; provided, however,
that the Company will pay Cash for fractional interests in a share of Common Stock. For purposes of determining the existence of potential fractional interests, all Securities subject to repurchase by
the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose Securities are repurchased pursuant to Section 4.1
shall receive the same percentage of Cash or, if permitted hereunder, shares of Common Stock in payment of the Repurchase Price for such Securities, (i) except as provided in this
Section 4.2(a) with regard to the payment of Cash in lieu of fractional shares of Common Stock and (ii) in the event that the Company is unable to purchase the Securities of the Holder
or Holders for shares of Common Stock because any necessary qualifications or registration of the shares of Common Stock under applicable securities laws cannot be obtained, the Company may purchase
the Securities of such Holder or Holders for Cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the
Company has given its notice of repurchase right to Holders except in the event of a failure to satisfy, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the
Repurchase Date, any condition to the payment of the Repurchase Price in whole or in part, in shares of Common Stock. 

        (b)   If
the Company elects to pay all or a portion of the Repurchase Price of Securities in respect of which a Repurchase Notice pursuant to Section 4.1(c) has been
given in shares of Common Stock, the number of shares of Common Stock to be issued shall be equal to the portion of the Repurchase Price to be paid in shares of Common Stock divided by the Market
Price of one share of Common Stock, subject to satisfaction of the conditions set forth in the second succeeding paragraph. 

        The
Company will not issue any fraction of a share of Common Stock in payment of the Repurchase Price. Instead, the Company will make a Cash payment (calculated to the nearest cent) 

23

 

equal
to such fraction multiplied by the Market Price of one share of Common Stock. If a Holder elects to have more than one Security purchased, the number of shares of Common Stock shall be based on
the aggregate amount of Securities to be purchased. 

        The
Company's right to exercise its election to repurchase Securities through the issuance of shares of Common Stock shall be conditioned upon: 

        (i)    the
registration of such shares of Common Stock under the Securities Act and the Exchange Act, in each case, if required; 

        (ii)   any
qualification or registration of such shares of Common Stock under applicable state securities laws, if necessary, or the availability of an exemption from such
qualification and registration; 

        (iii)  the
listing of such shares of Common Stock on a United States national securities exchange or the quotation of such shares of Common Stock in an inter-dealer quotation
system of any registered United States national securities association; and 

        (iv)  the
receipt by the Trustee of an Officers' Certificate stating: (A) that the terms of the issuance of the shares of Common Stock are in conformity with this
Indenture; (B) that the shares of Common Stock to be issued in payment of the Repurchase Price in respect of Securities have been duly authorized and, when issued and delivered pursuant to the
terms of this Indenture in payment of the Repurchase Price in respect of Securities, will be validly issued, fully paid, non-assessable and free from preemptive rights; (C) that the
conditions in this clause (iv)(A) and (iv)(B) above, the conditions in clauses (i)-(iii) above and the condition set forth in the second succeeding paragraph regarding issuance of a
press release have been satisfied in all material respects; and (D) the number of shares of Common Stock to be issued for each $1,000 principal amount of Securities and the Sale Price of a
share of Common Stock on each Trading Day during the period commencing on the first Trading Day of the period during which the Market Price is calculated and ending on the Trading Day immediately
preceding the Repurchase Date; and 

        (v)   the
receipt by the Trustee of an Opinion of Counsel stating that: (A) the shares of Common Stock to be issued in payment of the Repurchase Price in respect of
Securities have been duly authorized, and when issued and delivered pursuant to the terms of this Indenture in payment of the Repurchase Price in respect of Securities, will be validly issued, fully
paid and non-assessable and, to the best of such counsel's knowledge, free from preemptive rights; and (B) the conditions in clauses (i) through (iii) above have been
satisfied in all material respects. 

        If
the foregoing conditions are not satisfied with respect to a Holder or Holders prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase
Date, and the Company has elected to repurchase the Securities pursuant to this Section 4.2 through the issuance of Common Stock, the Company shall pay the entire Repurchase Price of the
Securities of such Holder or Holders in Cash. 

        Upon
determination of the actual number of shares of Common Stock to be issued upon repurchase of Securities, the Company shall be required to disseminate a press release through a
public medium as is customary for such a press release. 

        (c)    Covenants of the Company.    All shares of Common Stock delivered upon repurchase of the Securities shall be
newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. 

        (d)    Taxes.    If a Holder of a repurchased Security is paid in shares of Common Stock, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on such issue of shares of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the shares of
Common Stock to be issued in a name other than the Holder's name. The 

24

 

Paying
Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay
any tax which will be due because the shares of Common Stock are to be issued in a name other than the Holder's name. Nothing contained herein shall preclude any income tax withholding required by law
or regulations. 

        Section 4.3.    Effect of Repurchase Notice.    

        Upon
receipt by the Paying Agent of the Repurchase Notice specified in Section 4.1(c), the Holder of the Security in respect of which such Repurchase Notice was given shall
(unless such Repurchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to receive solely the Repurchase Price with respect to such Security. Such Repurchase Price
shall be paid to such Holder, subject to receipts of Cash and/or securities by the Paying Agent, promptly following the later of (a) the Repurchase Date with respect to such Security (provided
the conditions in Section 4.1 (c) have been satisfied) and (b) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by
Section 4.1(c). Securities in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article XII on or after the date of the delivery
of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn as specified in the following paragraph. 

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

        (a)   the
certificate number, if any, or the appropriate Depositary procedures, if applicable, of the Security in respect of which such notice of withdrawal is being
submitted; 

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

        (c)   the
principal amount, if any, of such Security which remains subject to the original Repurchase Notice and which has been or will be delivered for repurchase by the
Company. 

        Section 4.4.    Deposit of Repurchase Price.    

        Prior
to 10:00 a.m., New York City time, on the applicable Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of
any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of Cash (in immediately available funds if deposited on such Business Day)
and/or shares of Common Stock, if permitted hereunder, sufficient to pay the aggregate Repurchase Price of all the Securities or portions thereof which are to be repurchased on such Repurchase Date. 

        If
the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the Business Day immediately following the applicable Repurchase Date, Cash
and/or shares of Common Stock, if permitted hereunder, sufficient to pay the Repurchase Price of any Securities for which a Repurchase Notice has been tendered and not withdrawn pursuant to
Section 4.3, then, immediately after such Repurchase Date, such Securities will cease to be outstanding and interest (including, Contingent Interest, if any) and Additional Amounts, if any, on
such Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to
receive the Repurchase Price upon delivery of such Securities). 

        As
soon as practicable on and after the Repurchase Date, the Company shall deliver to each Holder entitled to receive shares of Common Stock through the Paying Agent, a certificate
(other than in the case of Holders of Securities in book-entry form with DTC, which shares shall be delivered in 

25

 

accordance
with DTC customary practices) for the number of full shares of Common Stock issuable in payment of the Repurchase Price and Cash in lieu of any fractional interests. The person in whose
name the certificate for the shares of Common Stock is registered shall be treated as a holder of record of shares of Common Stock on the Repurchase Date. No payment or adjustment will be made for
dividends on the shares of Common Stock the record date for which occurred on or prior to the Repurchase Date. 

        Section 4.5.    Securities Repurchased in Part.    

        Any
Certificated Security which is to be repurchased only in part 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 in form 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 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 repurchased. 

        Section 4.6.    Covenant to Comply With Securities Laws Upon Repurchase of Securities.    

        When
complying with the provisions of Section 4.1 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: 

        (a)   comply
with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act, as applicable; 

        (b)   file
the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, as applicable; and 

        (c)   otherwise
comply with all federal and state securities laws so as to permit the rights and obligations under Article IV to be exercised in the time and in the
manner specified therein. 

        To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article IV, the Company's compliance with such laws and regulations
shall not in and of itself cause a breach of its obligations under this Article IV. 

        Section 4.7.    Repayment to the Company.    

        The
Paying Agent shall return to the Company any Cash or shares of Common Stock that remains unclaimed for two years, together with interest or dividends, if any, thereon, held by it for
the payment of the Repurchase Price; provided, however, to the extent that the aggregate amount of Cash or shares of Common Stock deposited by the
Company pursuant to Section 4.4 exceeds the aggregate Repurchase Price of the Securities or portions thereof which the Company is obligated to repurchase on the Repurchase Date, then, promptly
after the Repurchase Date, the Paying Agent shall return any such excess to the Company. 

 
 

ARTICLE V    
    
    REPURCHASE AT THE OPTION OF HOLDERS
  UPON A FUNDAMENTAL CHANGE    
    

        Section 5.1.    Fundamental Change Put.    

        (a)    General.    If a Fundamental Change occurs at any time prior to April 15, 2008, each Holder will have
the right to require the Company to repurchase all of its Securities not previously called for 

26

 

redemption,
or any portion of such Securities, at a purchase price equal to 100% of the principal amount of all such Securities, plus accrued and unpaid interest, including Contingent Interest, if
any, on such Securities to, but not including, the Fundamental Change Repurchase Date (the "Fundamental Change Repurchase Price"), subject to
satisfaction by or on behalf of any Holder of the requirements set forth in Section 5.2(c). The date the Company shall repurchase the Securities pursuant to this Section 5.1 (the
"Fundamental Change Repurchase Date") must be within 30 days of the date of the mailing of the Fundamental Change Company Notice under
Section 5.1 (b). No Holder shall have the right to require the Company to repurchase its Securities under this Article V if a Fundamental Change occurs on or after April 15, 2008. 

        A
"Fundamental Change" is any transaction or event (whether by means of an exchange offer, liquidation, tender offer, consolidation,
merger, combination, reclassification, recapitalization or otherwise) in connection with which all or substantially all of the Common Stock is exchanged for, converted into, acquired for or
constitutes solely the right to receive, consideration (excluding Cash payments for fractional shares) which is not all or substantially all common stock that (i) is listed on, or immediately
after the transaction or event will be listed on, a United States national securities exchange, or (ii) is approved, or immediately after the transaction or event will be approved, for
quotation on the Nasdaq National Market or any similar United States system or automated dissemination of quotations of securities prices. 

        (b)    Notice of Fundamental Change.    No later than 30 days after the occurrence of a Fundamental Change that
occurs prior to April 15, 2008, the Company shall mail a written notice of Fundamental Change (the "Fundamental Change Company Notice") by first
class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall include a form of
Fundamental Change Repurchase Notice to be completed by the Holder and shall briefly state, as applicable: 

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

        (ii)   that
the Holder has a right to require the Company to repurchase the Holder's Securities; 

        (iii)  the
date by which the Fundamental Change Repurchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the Fundamental Change repurchase
right; 

        (iv)  the
Fundamental Change Repurchase Date; 

        (v)   the
Fundamental Change Repurchase Price; 

        (vi)  whether
the Fundamental Change Repurchase Price will be paid in Cash or shares of Applicable Stock, or a combination thereof and, in the case of a combination, the
percentage of each; 

        (vii) if
the Company elects to pay the Fundamental Change Repurchase Price in shares of Applicable Stock or a combination of Cash and shares of Applicable Stock, that the
number of shares of Applicable Stock each Holder will receive will equal the portion of the Fundamental Change Repurchase Price to be paid in shares of Applicable Stock divided by the Market Price of
one share of Applicable Stock; 

        (viii) if
the Company elects to pay the Fundamental Change Repurchase Price in shares of Applicable Stock or a combination of Cash and shares of Applicable Stock, the method
of calculating the Market Price of the shares of Applicable Stock; 

        (ix)  that
because the Market Price of one share of Applicable Stock will be determined prior to the Fundamental Change Repurchase Date, Holders of the Securities will bear
the market risk that the shares of Applicable Stock to be received will decline in value between the date such Market Price is determined and the Fundamental Change Repurchase Date; 

27

  

        (x)   the
name and address of the Paying Agent and the Conversion Agent; 

        (xi)  the
Conversion Rate applicable on the Fundamental Change Company Notice Date; 

        (xii) that
the Securities as to which a Fundamental Change Repurchase Notice has been given may be converted if they are otherwise convertible pursuant to Article XII
only if the Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 

        (xiii) that
the Securities must be surrendered to the Paying Agent to collect payment; 

        (xiv) that
the Fundamental Change Repurchase Price for any Security as to which a Fundamental Change Repurchase Notice has been duly given and not withdrawn will be paid
promptly following the later of the Fundamental Repurchase Date and the time of surrender of such Security; 

        (xv) the
procedures the Holder must follow to exercise its put right under this Section 5.1; 

        (xvi) the
conversion rights, if any, of the Securities; 

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

        (xviii) that,
unless the Company defaults in making payment of such Fundamental Change Repurchase Price, interest and Additional Amounts, if any, on Securities surrendered
for repurchase by the Company will cease to accrue on and after the Fundamental Change Repurchase Price; and 

        (xix) the
CUSIP number(s) of the Securities. 

        At
the Company's request, the Trustee shall give the Fundamental Change Company Notice in the Company's name and at the Company's expense; provided,
however, the Company makes such request at least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such Fundamental
Change Company Notice must be given to the Holders in accordance with this Section 5.1(b); provided, further, that the text of the Fundamental
Change Company Notice shall be prepared by the Company. 

        (c)    Fundamental Change Repurchase Notice.    A Holder may exercise its right specified in Section 5.1
(a) upon delivery of a written notice of repurchase (a "Fundamental Change Repurchase Notice"), substantially in the form of  Exhibit C hereto, to
the Paying Agent at any time from the opening of business on the date of the Fundamental Change Company Notice until
5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date, stating: 

        (i)    the
certificate number of the Security which the Holder will deliver to be repurchased or the appropriate depositary procedures if Certificated Securities have not been
issued; 

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

        (iii)  that
such Security shall be repurchased on the Fundamental Change Repurchase Date pursuant to the terms and conditions specified in the Securities and in this
Indenture; and 

        (iv)  in
the event the Company elects, pursuant to Section 5.2, to pay the Fundamental Change Repurchase Price, in whole or in part, in shares of Applicable Stock but
such portion of the Fundamental Change Repurchase Price shall ultimately be paid to such Holder entirely in Cash because any of the conditions to payment of the Fundamental Change Repurchase Price in
shares of Applicable Stock is not satisfied prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date, as set forth in
Section 5.2(b), whether such Holder elects to (A) withdraw such Fundamental Change Repurchase Notice as to 

28

 

some
or all of the Securities to which such Fundamental Change Repurchase Notice relates (stating the principal amount and certificate numbers, if any, or the appropriate Depositary procedures, if
applicable, of the Securities as to which such withdrawal shall relate), or (B) receive Cash in respect of the entire Fundamental Change Repurchase Price for all Securities (or portions
thereof) to which such Fundamental Change Repurchase Notice relates. 

        The
delivery of such Security to the Paying Agent with, or at any time after delivery of, the Fundamental Change Repurchase Notice (together with all necessary endorsements) 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 5.1 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof
set forth in the related Fundamental Change Repurchase Notice. 

        If
a Holder, in such Holder's Fundamental Change Repurchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of Section 5.3, fails to
indicate such Holder's choice with respect to the election set forth in Section 5.1(c)(iv), such Holder shall be deemed to have elected to receive Cash in respect of the entire Fundamental
Change Repurchase Price for all Securities subject to such Fundamental Change Repurchase Notice in the circumstances set forth in such Section 5.1 (c) (iv). 

        The
Company shall repurchase from the Holder thereof, pursuant to this Section 5.1, a portion of a Security, so long as 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 5.1 shall be consummated by the delivery of the consideration to be received by the Holder
promptly following the later of the Fundamental Change Repurchase Date and the time of delivery of the Security. 

        Notwithstanding
anything contained herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 5.1(c)
shall have the right to withdraw such Fundamental Change Repurchase Notice at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change
Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 5.3. 

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

        Section 5.2.    The Company's Right to Elect Manner of Payment of Fundamental Change Repurchase Price.    

        (a)   The
Securities to be repurchased with respect to any Fundamental Change Repurchase Date pursuant to Section 5.1(a) may be paid for at the election of the Company
in Cash or shares of Applicable Stock, or in any combination of Cash and shares of Applicable Stock, subject to the conditions set forth in Section 5.2(b). The Company shall designate, in the
Fundamental Change Company Notice delivered pursuant to Section 5.1(b), whether the Company will repurchase the Securities for Cash or shares of Applicable Stock, or, if a combination thereof,
the percentages of the Fundamental Change Repurchase Price in respect of which it will pay in Cash or shares of Applicable Stock; provided,  however, that
the Company will pay Cash for fractional interests in shares of Applicable Stock. For purposes of determining the existence of potential
fractional interests, all Securities subject to repurchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder
whose Securities are repurchased pursuant to Section 5.1 shall receive the same percentage of Cash or shares of Applicable Stock in payment of the Fundamental Change Repurchase Price for such
Securities, except (i) as provided in this Section 5.2(a) 

29

 

with
regard to the payment of Cash in lieu of fractional shares of Applicable Stock and (ii) in the event that the Company is unable to purchase the Securities of a Holder or Holders for shares
of Applicable Stock because any necessary qualifications or registrations of the shares of Applicable Stock under applicable securities laws cannot be obtained, the Company may purchase the Securities
of such Holder or Holders for Cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given
its Fundamental Change Company Notice to Holders except in the event of a failure to satisfy, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental
Change Repurchase Date, any condition to the payment of the Fundamental Change Repurchase Price in whole or in part, in shares of Applicable Stock. 

        (b)   If
the Company elects to pay all or a portion of the Fundamental Change Repurchase Price of Securities in respect of which a Fundamental Change Repurchase Notice
pursuant to Section 5.1(c) has been given in Applicable Stock, the number of shares of Applicable Stock to be issued shall be equal to (i) the portion of the Fundamental Change
Repurchase Price to be paid in Applicable Stock divided by (ii) the Market Price of one share of Applicable Stock, subject to satisfaction of the conditions set forth in the second succeeding
paragraph. 

        The
Company will not issue any fraction of a share of Applicable Stock in payment of the Fundamental Change Repurchase Price. Instead, the Company will make a Cash payment (calculated to
the nearest cent) equal to such fraction multiplied by the Market Price of one share of Applicable Stock. If a Holder elects to have more than one Security purchased, the number of shares of
Applicable Stock shall be based on the aggregate amount of Securities to be purchased. 

        The
Company's right to exercise its election to repurchase Securities through the issuance of shares of Applicable Stock shall be conditioned upon: 

        (i)    the
registration of such shares of Applicable Stock under the Securities Act and the Exchange Act, in each case, if required; and 

        (ii)   any
qualification or registration of such shares of Applicable Stock under applicable state securities laws, if necessary, or the availability of an exemption from such
qualification and registration; 

        (iii)  the
receipt by the Trustee of an Officers' Certificate stating (A): that the terms of the issuance of the shares of Applicable Stock are in conformity with this
Indenture; (B) that the shares of Applicable Stock to be issued in payment of the Fundamental Change Repurchase Price in respect of Securities have been duly authorized and, when issued and
delivered pursuant to the terms of this Indenture in payment of the Fundamental Change Repurchase Price in respect of Securities, will be validly issued, fully paid, non-assessable and
free from preemptive rights; (C) that the conditions in this clause (iii)(A) and (iii)(B) above, the conditions in clauses (i)-(ii) above and the condition set forth in the second
succeeding paragraph regarding issuance of a press release have been satisfied in all material respects; and (D) the number of shares of Applicable Stock to be issued for each $1,000 principal
amount of Securities and the Sale Price of a share of Applicable Stock on each Trading Day during the period commencing on the first Trading Day of the period during which the Market Price is
calculated and ending on the Trading Day immediately preceding the Fundamental Change Repurchase Date; and 

        (iv)  the
receipt by the Trustee of an Opinion of Counsel stating that: (A) the shares of Applicable Stock to be issued by the Company in payment of the Fundamental
Change Repurchase Price in respect of Securities have been duly authorized, and when issued and delivered pursuant to the terms of this Indenture in payment of the Fundamental Change Repurchase Price
in respect of Securities, will be validly issued, fully paid and non-assessable and, 

30

 

to
the best of such counsel's knowledge, free from preemptive rights; and (B) the conditions in clauses (i) and (ii) above have been satisfied in all material respects. 

        If
the foregoing conditions are not satisfied with respect to a Holder or Holders prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental
Change Repurchase Date, and the Company has elected to repurchase the Securities pursuant to this Section 5.2 through the issuance of shares of Applicable Stock, the Company shall pay the
entire Fundamental Change Repurchase Price of the Securities of such Holder or Holders in Cash. Upon determination of the actual number of shares of Applicable Stock to be issued upon repurchase of
Securities, the Company shall be required to disseminate a press release through a public medium as is customary for such a press release. 

        (c)    Covenants of the Company.    All shares of Applicable Stock delivered upon repurchase of the Securities shall
be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. 

        (d)    Taxes.    If a Holder of a repurchased Security is paid in shares of Applicable Stock, the Company shall pay
any documentary, stamp or similar issue or transfer tax due on such issue of Applicable Stock. However, the Holder shall pay any such tax which is due because the Holder requests the Applicable Stock
to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the shares of Applicable Stock being issued in a name other than the Holder's
name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Applicable Stock are to be issued in a name other than the Holder's name. Nothing contained
herein shall preclude any income tax withholding required by law or regulations. 

        Section 5.3.    Effect of Fundamental Change Repurchase Notice.    

        Upon
receipt by the Paying Agent of the Fundamental Change Repurchase Notice specified in Section 5.1(c), 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 the following paragraph) thereafter be entitled to receive solely the Fundamental
Change Repurchase Price with respect to such Security. Such Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipts of Cash and/or securities by the Paying Agent,
promptly following the later of (a) the Fundamental Change Repurchase Date with respect to such Security (provided the conditions in Section 5.1 (c) have been satisfied) and
(b) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 5.1(c). Securities in respect of which a Fundamental Change
Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article XII 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 the following paragraph. 

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

        (a)   the
principal amount of the Security with respect to which such notice of withdrawal is being submitted; 

        (b)   the
certificate number, if any, or the appropriate Depository procedures, if applicable, of the Security in respect of which such notice of withdrawal is being
submitted; and 

31

 

        (c)   the
principal amount, if any, of such Security which remains subject to the original Fundamental Change Repurchase Notice and which has been or will be delivered for
repurchase by the Company. 

        Section 5.4.    Deposit of Fundamental Change Repurchase Price.    

        Prior
to 10:00 a.m., New York City time, on the applicable Fundamental Change Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary
or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of Cash (in immediately available funds if deposited on
such Business Day) and/or Applicable Stock, if permitted hereunder, sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Securities or portions thereof which are to be
repurchased on such Fundamental Change Repurchase Date. 

        If
the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the Business Day immediately following the applicable Fundamental Change
Repurchase Date, Cash and/or Applicable Stock, if permitted hereunder, sufficient to pay the Fundamental Change Repurchase Price of any Securities for which a Fundamental Change Repurchase Notice has
been tendered and not withdrawn pursuant to Section 5.3, then, immediately after such Fundamental Change Repurchase Date, such Securities will cease to be outstanding and interest and
Additional Amounts, if any, on such Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate
(other than the right to receive the Fundamental Change Repurchase Price upon delivery of such Securities). 

        As
soon as practicable on and after the Fundamental Change Repurchase Date, the Company shall deliver to each Holder entitled to receive shares of Applicable Stock through the Paying
Agent, a certificate (other than in the case of Holders of Securities in book-entry form with the Depositary, which shares shall be delivered in accordance with the Depositary customary
practices) for the number of full shares of Applicable Stock issuable in payment of the Fundamental Change Repurchase Price and Cash in lieu of any fractional interests. The person in whose name the
certificate for the shares of Applicable Stock is registered shall be treated as a holder of record of Applicable Stock on the Fundamental Change Repurchase Date. No payment or adjustment will be made
for dividends on the shares of Applicable Stock the record date for which occurred on or prior to the Fundamental Change Repurchase Date. 

        Section 5.5.    Securities Repurchased in Part.    

        Any
Certificated Security which is to be repurchased only in part 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 in form 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 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 repurchased. 

        Section 5.6.    Covenant to Comply With Securities Laws Upon Repurchase of Securities.    

        When
complying with the provisions of Section 5.1 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: 

        (a)   comply
with Rule 13e- 4 and Rule 14e-1 (or any successor provision) under the Exchange Act, as applicable; 

32

 

        (b)   file
the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, as applicable; and 

        (c)   otherwise
comply with all federal and state securities laws so as to permit the rights and obligations under Article V to be exercised in the time and in the
manner specified therein. 

        To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article V, the Company's compliance with such laws and regulations
shall not in and of itself cause a breach of its obligations under this Article V. 

        Section 5.7.    Repayment to the Company.    

        The
Paying Agent shall return to the Company any cash or shares of Applicable Stock that remain unclaimed for two years, together with interest or dividends, if any, thereon, held by it
for the payment of the Fundamental Change Repurchase Price; provided, however, to the extent that the aggregate amount of Cash or shares of Applicable
Stock deposited by the Company pursuant to Section 5.4 exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof which the Company is obligated to
repurchase as of the Fundamental Change Repurchase Date then, promptly after the Fundamental Change Repurchase Date, the Paying Agent shall return any such excess to the Company. 

 
 

ARTICLE VI    
    
    COVENANTS    
    

        Section 6.1.    Payment of Securities.    

        The
Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities or pursuant to this Indenture. Principal amount,
Redemption Price, Repurchase Price and Fundamental Change Repurchase Price and accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, shall be considered
paid on the applicable date due if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in accordance with this Indenture, Cash or securities, if permitted hereunder,
sufficient to pay all such amounts then due. The Company shall, to the fullest extent permitted by law, pay interest on overdue principal and overdue installments of interest and Additional Amounts,
if any, at the rate borne by the Securities per annum. All references in this Indenture or the Securities to interest shall be deemed to include Additional Amounts, if any, payable pursuant to the
Registration Rights Agreement. 

        Payment
of the principal of and interest (including Contingent Interest, if any) and Additional Amounts, if any, on the Securities shall be in Cash, Common Stock or in Applicable Stock,
as provided herein. 

        The
Company shall pay interest (including Contingent Interest, if any) and Additional Amounts, if any, on the Securities to the Person in whose name the Securities are registered at the
close of business on the Regular Record Date next preceding the corresponding Interest Payment Date. Any such interest and Additional Amounts, if any, not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may be paid (a) to the Person in whose name the Securities are registered at the close of business on a Special
Record Date for the payment of such defaulted interest and Additional Amounts, if any, to be fixed by the Trustee, notice whereof will be
given to the Holders not less than 10 days prior to such Special Record Date or (b) at any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be required by such exchange. 

        If
a Security is redeemed pursuant to Article III hereof or the Holder elects to require the Company to repurchase such Security pursuant to either Article IV or
Article V hereof on a date that is after the Regular Record Date and prior to the corresponding Interest Payment Date, interest 

33

 

(including
Contingent Interest, if any) and Additional Amounts, if any, accrued and unpaid on such Security to, but not including, the applicable Redemption Date, Repurchase Date or Fundamental Change
Repurchase Date will be paid to the same Holder to whom the Company pays the principal of such Security regardless of whether such Holder was the registered Holder on the Regular Record Date
immediately preceding the applicable Redemption Date, Repurchase Date or Fundamental Change Repurchase Date. 

        Holders
must surrender the Securities to the Paying Agent to collect payment of principal. Payment of interest (including Contingent Interest, if any) and Additional Amounts, if any, on
Certificated Securities will be made by check mailed to the address of the Person entitled thereto as such address appears in the Register. Notwithstanding the foregoing, so long as the Securities are
registered in the name of a Depositary or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its
nominee. 

        Upon
a determination by the Company that Holders will be entitled to receive Contingent Interest which will become payable during a Contingent Interest Period, on or prior to the first
day of such Contingent Interest Period, the Company shall deliver an Officer's Certificate to the Trustee setting forth the amount of such Contingent Interest per $1,000 principal amount of Securities
and shall issue a press release through a public medium as is customary for such a press release. 

        Section 6.2.    SEC and Other Reports to the Trustee.    

        The
Company shall ensure delivery to the Trustee within 15 days after it files 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 in accordance with TIA Section 314(a); provided,
however, that the Company shall not be required to deliver to the Trustee any material for which the Company has sought and received confidential treatment by the SEC. In the
event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee and to each Holder, within
15 days after it would have been required to file such reports with the SEC, annual and quarterly consolidated financial statements
substantially equivalent to financial statements that would have been included in reports filed with the SEC if the Company was subject to the requirements of Section 13 or 15(d) of the
Exchange Act, including, with respect to annual information only, a report thereon by the Company's certified independent public accountants as such would be required in such reports to the SEC and,
in each case, together with a management's discussion and analysis of financial condition and results of operations which would be so required. The Company also shall 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 covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates). 

        Section 6.3.    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, 2003) an
Officers' Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in Default in the performance and observance of any of the terms, provisions and conditions of
this Indenture and if the Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. 

34

 

        Section 6.4.    Further Instruments and Acts.    

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

        Section 6.5.    Maintenance of Office or Agency of the Trustee, Registrar, Paying Agent and Conversion
Agent.    

        The
Company will maintain in the Borough of Manhattan, The City of New York, 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, redemption, repurchase or conversion and where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served. The office of BNY Western Trust Company, The Bank of New York—Debt Processing Window, 101 Barclay Street, New York,
New York 10286, shall initially be such office or agency for all of the aforesaid purposes. 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 14.2. 

        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 in the Borough of Manhattan, The City of New York, for such purposes. 

        Section 6.6.    Delivery of Information Required Under Rule 144A.    

        At
any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial
owner of shares of Common Stock issued upon conversion thereof, the Company will make available the information required pursuant to Rule 144A(d)(4) under the Securities Act 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, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security;  provided, however,
 that the Company shall not be required to furnish such information in connection with any request made on or after the date which is
two years from the later of the date such security was last acquired from the Company or an "affiliate" (as defined under Rule 144 under the Securities Act) of the Company. Whether a person is
a beneficial owner shall be determined by the Company to the Company's reasonable satisfaction. 

        Section 6.7.    Waiver of Stay, Extension or Usury Laws.    

        The
Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the
principal amount, Redemption Price, Repurchase Price or Fundamental Change Repurchase Price in respect of Securities, or any interest (including Contingent Interest, if any) and Additional Amounts, if
any, on such amounts, 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 will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted. 

35

  

        Section 6.8.    Statement by Officers as to Default.    

        The
Company shall deliver to the Trustee, as soon as practicable and in any event within five Business Days after the Company becomes aware of the occurrence of any Default or Event of
Default or, an Officers' Certificate setting forth the details of such Default or Event of Default and the action which the Company proposes to take with respect thereto.

    SUCCESSOR CORPORATION    
    

        Section 7.1.    When Company May Merge or Transfer Assets.    

        The
Company shall not consolidate with, merge with or into, or sell, assign, convey transfer or lease its properties and assets substantially in their entirety (computed on a
consolidated basis) to any Person, unless: 

        (a)   either
(i) the Company is the surviving entity or (ii) the successor or transferee (the "successor corporation") is a corporation organized and existing
under the laws of the United States, any State thereof, or the District of Columbia and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, all of the
obligation of the Company under the Securities and the Indenture; 

        (b)   immediately
after giving effect to such transaction, no Default shall exist; and 

        (c)   the
Company shall have delivered to the Trustee an Officers' Certificate and, if requested by the Trustee, an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer, sale, lease or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this
Article VII and that all conditions precedent herein provided for relating to such transaction have been satisfied. 

        Section 7.2.    Successor Corporation Substituted    

        Upon
any consolidation with or merger into any corporation, or any conveyance, transfer or lease of the properties and assets of the Company substantially in their entirety in accordance
with Section 7.1, the successor corporation formed by such consolidation or which the Company is merged or to which such conveyance, transfer or lease 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 corporation had been named as the Company herein. 

 
 

ARTICLE VIII    
    
    DEFAULTS AND REMEDIES    
    

        Section 8.1.    Events of Default.    

        So
long as any Securities are outstanding, each of the following shall be an "Event of Default": 

        (a)   the

        (b)   the

Company fails to satisfy its conversion obligation with respect to any portion of the principal amount of any Security following the exercise by the Holder of the
right to convert such Security into shares of Common Stock (or Cash or a combination of shares of Common Stock and 

36

 

Cash,
if the Company so elects) pursuant to and in accordance with Article XII, unless such failure is cured within five days after written notice of default is given to the Company by the
Trustee or the Holder of such Security; 

        (d)   the
Company defaults in its obligation to redeem any Security, or any portion thereof, called for redemption by the Company pursuant to and in accordance with
Article III; 

        (e)   the
Company defaults in its obligation to pay the Repurchase Price or the Fundamental Change Repurchase Price, as applicable, with respect to any Security, or any
portion thereof, upon the exercise by the Holder of such Holder's right to require the Company to repurchase such Securities pursuant to and in accordance with Article IV or V, as applicable; 

        (f)    the
Company fails to comply with any of its agreements or covenants in the Securities or this Indenture (other than those referred to in clause (a) through
(e) above) and such failure continues for 60 days after receipt by the Company of a Notice of Default (defined below); 

        (g)   the
acceleration of maturity of any indebtedness of the Company (other than Non-Recourse Indebtedness), at any one time, in an amount in excess of the
greater of (i) $25,000,000 and (ii) 5% of Consolidated Net Tangible Assets, unless the acceleration is rescinded, stayed or annulled within 30 days after receipt by the Company of
a Notice of Default; 

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

        (i)    commences
a voluntary case or proceeding; 

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

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

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

        (v)   files
a petition in bankruptcy or answer or consent seeking reorganization or relief; or

and
the order of decree remains unstayed and in effect for 60 days. 

        A
Default under clause (f) or (g) above is not 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 the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in
clause (f) or (g) above 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."

37

 

        Section 8.2.    Acceleration.    

        If
an Event of Default (other than an Event of Default specified in Section 8.1 (h) or (i)) occurs and is continuing, 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 plus accrued and unpaid interest
(including Contingent Interest, if any) and 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 8.1 (h) or (i) occurs and is continuing, the principal amount plus accrued and unpaid interest (including Contingent
Interest, if any) and 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 not less than 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 rescind an acceleration and its consequences 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 plus accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, that have become due solely as a result of acceleration. No such
rescission shall affect any subsequent Default or impair any right consequent thereto. 

        Section 8.3.    Other Remedies.    

        If
an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the principal amount plus accrued
and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, on the Securities or to enforce the performance of any provision of the Securities 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 8.4.    Waiver of Past Defaults.    

        Subject
to Sections 8.7 and 11.2, the Holders of not less than 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 an existing Default and its consequences except: 

        (a)   an
Event of Default in the payment of the principal of, any premium or interest (including Contingent Interest, if any) on, or any Additional Amounts with respect to,
any Security; or 

        (b)   a
Default in respect of any provision of this Indenture or the Securities, which, under Section 11.2, cannot be amended or modified without the consent of each
Securityholder affected thereby. 

        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 8.4 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. 

38

 

        Section 8.5.    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 in good faith is prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity or security
satisfactory to it. This Section 8.5 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted
by the TIA. 

        Section 8.6.    Limitation on Suits.    

        A
Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless: 

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

        (b)   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; 

        (c)   such
Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 

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

        (e)   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 request
during such 60-day period. 

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

        Section 8.7.    Rights of Holders to Receive Payment or to Convert.    

        Notwithstanding
any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, Redemption Price, Repurchase Price, Fundamental Change
Repurchase Price or interest (including Contingent Interest, if any) and Additional Amounts, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in
the Securities and in this Indenture, and to convert such Securities in accordance with Article XII, or to bring suit for the enforcement of any such payment on or after such respective dates
or the right to convert, is absolute and unconditional and shall not be impaired or affected adversely without the consent of such Holder. 

        Section 8.8.    Collection Suit by Trustee.    

        If
an Event of Default described in Section 8.1(a), (b), (d) or (e) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an
express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and the amounts provided for in Section 9.7. 

        Section 8.9.    Trustee May File Proofs of Claim.    

        In
case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount, Redemption
Price, Repurchase 

39

 

Price,
Fundamental Change Repurchase Price or interest and 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, by intervention in such proceeding or otherwise: 

        (a)   to
file and prove a claim for the whole amount of the principal amount, Redemption Price, Repurchase Price, Fundamental Change Repurchase Price, or interest and
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 (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 9.7) and of the Holders allowed in such judicial proceeding, and 

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

and
any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.7. 

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

        Section 8.10.    Priorities.    

        (a)   If
the Trustee collects any money pursuant to this Article VIII, it shall pay out the money in the following order: 

        FIRST:
to the Trustee for amounts due under Section 9.7; 

        SECOND:
to Securityholders for amounts due and unpaid on the Securities for the principal amount, Redemption Price, Repurchase Price, Fundamental Change Repurchase Price or interest
(including Contingent Interest, if any) and Additional Amounts, if any, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the
Securities; and 

        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 8.10. 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 8.11.    Undertaking for Costs.    

        In
any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion
may require the filing by any party litigant (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 8.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 8.7 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at
the time outstanding. This Section 8.11 shall be in lieu of 

40

 

Section 315(e)
of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

        Section 8.12.    Restoration of Rights and Remedies.    

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

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

        (i)    the

specifically required to be furnished to the Trustee, the Trustee shall examine the 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 9.1(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.

Section (c) does not limit the effect of Section (b) of this Section 9.1;

Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer unless it is proved that the Trustee was negligent in ascertaining

hereby expressly excluded from this Indenture, as permitted by the TIA. 

        (d)   Every

indemnity or security satisfactory to it against any loss, liability or expense. 

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

notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties; 

        (b)   whenever
in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any

        (c)   the

not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 

        (d)   the
Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith which it believes to be authorized or within its rights or
powers conferred under this Indenture; 

        (e)   the
Trustee may consult with counsel selected by it and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action

        (f)    the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders,

        (g)   any
request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of

Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 

        (i)    the
Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event 

42

 

which
is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 

        (j)    the
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall
be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other person employed to act hereunder; and 

        (k)   the
Trustee may request that the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to

in any such certificate previously delivered and not superseded. 

        Section 9.3.    Individual Rights of Trustee.    

        The
Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Sections 9.10 and 9.11. 

        Section 9.4.    Trustee's Disclaimer.    

        The
Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use or application of the proceeds
from the Securities, it shall not be responsible for any statement in any registration statement for the Securities under the Securities Act or in any offering document for the Securities, this
Indenture or the Securities (other than its certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder. 

        Section 9.5.    Notice of Defaults.    

        If
a Default occurs and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the Default within 90 days after it occurs or, if later, within
15 days after it is known to the Trustee, unless such Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a
Default described in Section 8.1(a), (b) (d) or (e), 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 and provided, further, that in the case of any Default described in
Section 8.1(f), no such notice shall be given to Holders until at least 30 days after the occurrence thereof. 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. 

        Section 9.6.    Reports by Trustee to Holders.    

        Within
60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated
as of such May 15 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b). 

43

  

        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 and Common Stock 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 9.7.    Compensation and Indemnity.    

        The
Company agrees to: 

        (a)   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)   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 or willful misconduct or bad faith; and 

        (c)   fully
indemnify the Trustee, any predecessor Trustee and each of their directors and officers for, and to hold each of them harmless against, any and all loss, damage,
claim, liability, cost or expense (including reasonable attorney's fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without
negligence or willful misconduct or bad faith on the part of the Person so indemnified, arising out of or in connection with the acceptance or administration of this trust, including the reasonable
costs and expenses of defending against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any powers or
duties hereunder, or in connection with enforcing the provisions of this Section 9.7. 

        The
Trustee shall notify the Company promptly of any claim for which it may seek indemnity hereunder; provided, that a failure to notify
shall not relieve the Company of its obligations hereunder except to the extent the Company is materially prejudiced by such failure. The Company shall defend the claim and the Trustee shall provide
reasonable cooperation at the Company's expense in the
defense. The Trustee may have one such separate counsel and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company shall not be required to pay such
reasonable fees and expenses if it assumes the Trustee's defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the
Trustee in connection with such defense. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own willful
misconduct, negligence or bad faith. To secure the Company's payment obligations in this Section 9.7, 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, Redemption Price, Repurchase Price, Fundamental Change Repurchase Price or interest (including Contingent Interest, if
any) and Additional Amounts, if any, as the case may be, on particular Securities. 

        The
Company's payment obligations pursuant to this Section 9.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs
expenses after the occurrence of a Default specified in Section 8.1 (h) or (i), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute
expenses of administration under any Bankruptcy Law. 

44

 

        Section 9.8.    Replacement of Trustee.    

        The
Trustee may resign 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 9.8. 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. The Company shall remove the Trustee if: 

        (a)   the
Trustee fails to comply with Section 9.10; 

        (b)   the
Trustee is adjudged bankrupt or insolvent; 

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

        (d)   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 9.7. 

        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 at the expense of the Company any court of competent jurisdiction at the expense of the Company for the appointment of
a successor Trustee. 

        If
the Trustee fails to comply with Section 9.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee. 

        Section 9.9.    Successor Trustee by Merger.    

        If
the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or company, the resulting,
surviving or transferee corporation without any further act shall be the successor Trustee. 

        Section 9.10.    Eligibility; Disqualification.    

        The
Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its 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 contained herein shall prevent the Trustee from filing with the Commission the application
referred to in the penultimate paragraph of TIA Section 310(b). 

        Section 9.11.    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. 

45

 

 
 

ARTICLE X    
    
    DISCHARGE OF INDENTURE    
    

        Section 10.1.    Discharge of Liability on Securities.    

        When
(i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced or repaid pursuant to Section 2.7) for cancellation or
(ii) all outstanding Securities have become due and payable (whether at the Stated Maturity or upon acceleration, or on any Redemption Date, or with respect to any Repurchase Date or
Fundamental Change Repurchase Date, or upon conversion) and the Company deposits with the Paying Agent or Conversion Agent Cash, Common Stock or Applicable Stock, as applicable, sufficient to pay all
amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.7), and if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 9.7, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging
satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers' Certificate and Opinion of Counsel and at the cost and expense of the Company. 

        Section 10.2.    Repayment to the Company.    

        The
Trustee and the Paying Agent shall return to the Company upon written request any Cash 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 unclaimed property law. After return to the Company, Holders entitled to the Cash or securities must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Securityholders with respect to such Cash or
securities for that period commencing after the return thereof.

        (l)    add

provision of this Indenture or the Securities may be waived, in each case with the written consent or affirmative vote of the Holders of not less than a majority of the principal amount of the

consent approves the substance thereof. 

        After
an amendment under this Section 11.2 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 

        Nothing
contained in this Section 11.2 shall impair the ability of the Company and the Trustee to amend this Indenture or the Securities without the consent of any Securityholder
to provide for the assumption of the Company's obligations to the Holders of Securities in the case of a merger, consolidation, conveyance, transfer, sale, lease or other disposition pursuant to
Article VII. 

        Section 11.3.    Compliance with Trust Indenture Act.    

        Every
supplemental indenture executed pursuant to this Article shall comply with the TIA. 

        Section 11.4.    Revocation and Effect of Consents, Waivers and Actions.    

        Until
an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent
Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder's Security, even if notation of the consent, waiver or action is not made on the
Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder's Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Securityholder. 

        Section 11.5.    Notation on or Exchange of Securities.    

        Securities
authenticated and delivered after the execution of any supplemental indenture pursuant to this Article XI may, and shall if required by the Trustee, bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee

Trustee shall sign any supplemental indenture authorized pursuant to this Article XI if the amendment contained therein does not affect the rights, duties, liabilities or
immunities of the Trustee. 

48

 

If
it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 9.1)
shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. 

        Section 11.7.    Effect of Supplemental Indentures.    

        Upon
the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

 
 

ARTICLE XII    
    
    CONVERSION    
    

        Section 12.1.    Conversion Privilege.    

        Subject
to and upon compliance with the provisions of this Article XII, 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 or an integral multiple of $1,000) of such Security into shares of Common Stock at the Conversion Price in effect on the date of conversion only as follows: 

        (a)   during
any fiscal quarter (beginning with the third fiscal quarter of 2003) if the Sale Price of the Common Stock for at least 20 consecutive Trading Days in the
Measurement Period of the immediately preceding fiscal quarter exceeds 120% of the Conversion Price in effect on the last Trading Day of such Measurement Period (in the event that the Conversion Price
on such last Trading Day of such Measurement Period is not the same as the Conversion Price in effect for each of the Trading Days in such Measurement Period, the Conversion Agent shall make such
adjustments as it, in its discretion, deems appropriate in determining whether the foregoing condition has been met); 

        (b)   during
the five consecutive Trading Day period immediately following a 10 consecutive Trading Day period in which the Market Price per $1,000 principal amount of
Securities for each day of such 10 consecutive Trading Day period was less than 90% of the product of the Sale Price of the Common Stock on such Trading Day multiplied by the number of shares of
Common Stock issuable upon conversion of $1,000 in principal amount of the Securities (the condition specified in this subsection (b) being the "90% Market
Condition"); or 

        (c)   at
any time prior to 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date, if such Security has been called for
redemption pursuant to Article III hereof. 

        The
Conversion Agent shall, on behalf of the Company, determine at the end of each applicable period whether the Securities shall be convertible as a result of the occurrence of an event
specified in clause (a) or (b) above and, if the Securities shall be so convertible, the Conversion Agent shall promptly deliver to the Company and the Trustee written notice thereof.
Whenever the Securities shall become convertible pursuant to Section 12.1, the Company or, at the Company's request, the Trustee in the name and at the expense of the Company, shall notify the
Holders in writing of the event triggering such convertibility in the manner provided in Section 14.2, and the Company shall also publicly announce such information and publish it on the
Company's website. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 

49

 

        Section 12.2.    Conversion Procedure; Conversion Price; Fractional Shares.    

        (a)   Subject
to Section 12.2(e), each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares (calculated to the
nearest 1/100th of a share) of Common Stock. Subject to Section 12.2(e), the Security will be converted into shares of Common Stock at the Conversion Price therefor. 

        No
payment or adjustment shall be made in respect of dividends on the Common Stock or accrued interest or accrued and unpaid Contingent Interest, if any, on a converted Security, except
as described in Section 12.9 hereof. 

        The
Company shall not issue any fraction of a share of Common Stock in connection with any conversion of Securities, but instead shall make a Cash payment (calculated to the nearest
cent) equal to such fraction multiplied by the Sale Price of the Common Stock on the last Trading Day prior to the date of conversion. 

        Notwithstanding
the foregoing, a Security in respect of which a Holder has delivered a Purchase Notice or Fundamental Change Purchase Notice exercising such Holder's option to require
the Company to repurchase such Security may be converted only if such notice of exercise is withdrawn in accordance with Sections 4.3 or 5.3 hereof, as the case may be, prior to the close of business
on the Business Day immediately preceding the applicable Repurchase Date or Fundamental Change Repurchase Date, as the case may be. 

        (b)   Before
any Holder of a Security shall be entitled to convert the same into Common Stock or be entitled to the payment of any consideration upon a Principal Value
Conversion as described in Section 12.2(e), such Holder shall, in the case of Securities issued in global form, comply with the procedures of the Depository in effect at that time, 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 shall give written notice to the Company at said office
or place in the form of the Conversion Notice attached to the Security (the "Conversion Notice") that such Holder elects to convert the same and shall
state in writing therein the principal amount of Security to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be
issued. 

        Before
any such conversion, a Holder also shall pay all funds required, if any, relating to interest on the Securities, as provided in Section 12.9, and all taxes or duties, if
any, as provided in Section 12.8. 

        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 which shall be deliverable upon conversion shall
be computed on the basis of the aggregate principal amount of the Security (or specified portions thereof to the extent permitted thereby) so surrendered. Subject to the next succeeding sentence, the
Company will, as soon as practicable thereafter, issue and deliver at said office or place to such Holder of a Security, or to such Holder's nominee or nominees, certificates (other than in the case
of Holders of Securities in book-entry form with the Depositary, which shares shall be delivered in accordance with the Depositary customary practices) for the number of full shares of
Common Stock to which such Holder shall be entitled as aforesaid, together with Cash in lieu of any fraction of a share to which such Holder would otherwise be entitled. 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; provided, that in the case of
issuances of Common Stock described in Section 12.2(e), such issuances shall be made in accordance with the time periods set forth in such section. 

50

   
        If shares of Common Stock to be issued upon conversion of a Restricted Security are to be issued in the name of a Person other than the Holder of such Restricted Security, such Holder
must deliver to the Conversion Agent a certification in substantially the form set forth in a Transfer Certificate dated the date of surrender of such Restricted Security and signed by such Holder, as
to compliance with the restrictions on transfer applicable to such Restricted Security. The Company shall not be required to issue Common Stock upon conversion of any such Restricted Security to a
Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification, and the Registrar shall not be required to register Common Stock upon conversion
of any such Restricted Security in the name of a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification. 

        (c)   A
Security shall be deemed to have been converted as of the close of business on the date of the surrender of such Security for conversion as provided above, and the
person or persons entitled to receive the Common Stock issuable 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 such date. Upon conversion, all obligations under the Securities so converted will be deemed satisfied, including with respect to any accrued and unpaid interest (including Contingent Interest, if
any) and Additional Amounts, if any. 

        (d)   In
case any Certificated Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall, upon the written order of the Company,
authenticate and deliver to the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 12.8 hereof), a new Security or Securities in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Certificated Securities. 

        (e)   Notwithstanding
the foregoing, if on the conversion date of the Holder's conversion of a Security pursuant to the 90% Market Condition (such date, the
"90% Conversion Date") the Sale Price of the Common Stock is greater than the Conversion Price, the Holder converting a Security pursuant to the 90%
Market Condition shall receive, in lieu of a number of shares of Common Stock based on the Conversion Price, Cash or Common Stock or a combination of Cash and Common Stock, at the Company's sole
option, with a value equal to the principal amount of the Security so surrendered for conversion (such conversion, a "Principal Value Conversion"). Any
Common Stock to be delivered to the Holder by the Company upon a Principal Value Conversion shall be valued at the Sale Price of the Common Stock on the 90% Conversion Date. The Company shall notify
the Trustee and any surrendering Holder of Securities whose conversion is a Principal Value Conversion of such Principal Value Conversion by the second Trading Day following the 90% Conversion Date
and in such notice, state whether the Company shall pay to such Holder all or a portion of the principal amount of such Securities in Cash, Common Stock or a combination of Cash and Common Stock and,
if a combination, the percentages of the principal amount in respect of which it will pay in Cash or Common Stock. Subject to the satisfaction of all requirements for conversion under
Section 12.2, the Company shall use reasonable efforts to (A) pay any portion of the principal amount of Securities elected to be paid in Cash by the Company in a Principal Value
Conversion of the third Trading Day following the 90% Conversion Date and (B) deliver any portion of the principal amount of Securities elected to be paid by the Company in Common Stock in a
Principal Value Conversion on the fourth Trading Day following the 90% Conversion Date. 

        Section 12.3.    Adjustment of Conversion Price for Common Stock.    

        The
Conversion Price shall be adjusted from time to time as follows: 

        (a)   In
case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in shares of Common Stock
to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date next following the Record Date fixed for the determination of
stockholders 

51

 

entitled
to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction: 

          (i)  the
numerator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date fixed for such determination; and 

         (ii)  the
denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution. 

        Such
reduction shall become effective immediately after the opening of business on the day following the Record Date fixed for such determination. 

        If
any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion
Price which would then be in effect if such dividend or distribution had not been declared. 

        (b)   In
case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately
reduced, and conversely, in case the Company shall, at any time or from time to time while any of the Securities are outstanding, combine its outstanding shares of Common Stock into a smaller number
of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased.
In each such case, the Conversion Price shall be adjusted by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such subdivision or combination and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such subdivision or
combination. Such reduction or increase, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination
becomes effective. 

        (c)   In
case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue rights or warrants for a period expiring within
60 days after the date of announcement of such issuance (other than any rights or warrants referred to in Section 12.3(d)), to all holders of its shares of Common Stock entitling them to
subscribe for or purchase shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock), at a price per share (or having a conversion, exchange or
exercise price per share) less than the Sale Price of the Common Stock on the Business Day immediately preceding the date of the announcement of such issuance (treating the conversion, exchange or
exercise price per share of the securities convertible into or exchangeable or exercisable for Common Stock as equal to the quotient of (x) the sum of (i) the price for a unit of the
security convertible into or exchangeable or exercisable for Common Stock and (ii) any additional consideration initially payable upon the conversion, exchange or exercise of such security into
Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible, exchangeable or exercisable security), then the Conversion Price shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such date of announcement by a fraction: 

          (i)  the
numerator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares (or
convertible, exchangeable or exercisable securities) which the aggregate offering price of the total number of shares (or convertible, exchangeable or exercisable securities) so offered for
subscription or purchase (or the aggregate conversion, exchange or exercise price of the 

52

 

convertible
securities so offered) would purchase at the Sale Price of the Common Stock on the Business Day immediately preceding the date of the announcement of such issuance (determined by
multiplying such total number of shares so offered by the exercise price of such rights or warrants and dividing the product so obtained by such Sale Price); and 

         (ii)  the
denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the total number of
additional shares of Common Stock so offered for subscription or purchase (or into which the convertible, exchangeable or exercisable securities so offered are convertible, exchangeable or
exercisable). 

        Such
adjustment shall become effective immediately after the opening of business on the day following the date of announcement of such issuance. 

        To
the extent that shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) are not delivered pursuant to such rights or
warrants, upon the expiration or termination of such rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon
the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of
Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if
the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for
or purchase shares of Common Stock at less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration
received for such rights or warrants and the value of such consideration if other than Cash, to be determined in good faith by the Board of Directors of the Company. 

        (d)   (i) In
case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all holders
of its shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the Common Stock is not changed
or exchanged), shares of its Capital Stock (other than any dividends or distributions to which Section 12.3(a) applies), evidences of its Indebtedness or other non-Cash assets,
including securities, but excluding (x) any rights or warrants referred to in Section 12.3(c), (y) dividends or distributions of stock referred to in Section 12.3(a) and
(z) dividends and distributions paid exclusively in Cash (such capital stock, evidence
of its indebtedness, other non-Cash assets or securities being distributed hereinafter in this Section 12.3(d) called the "distributed
assets"), then, in each such case, subject to the other provisions of this Section 12.3(d), the Conversion Price shall be reduced so that the same shall be equal to the
price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction: 

        (A)  the
numerator of which shall be the Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so
distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date) (determined as provided in Section 12.3(f));
and 

        (B)  the
denominator of which shall be such Current Market Price. 

53

 

        Such
reduction shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or
distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. 

         (ii)  If
the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued
trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the
"Reference Period") used in computing the Current Market Price pursuant to Section 12.3(f) to the extent possible, unless the Board of Directors
determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders. 

        (iii)  In
the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company's Subsidiaries (a
"Spin-Off"), the Fair Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities
on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth Trading Day of those securities after the
effectiveness of the Spin-Off. In the event, however, that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the
Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities. 

        (iv)  Rights
or warrants distributed by the Company to all holders of its shares 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 or warrants, until the occurrence of a specified event or events ("Trigger
Event"), (x) are deemed to be transferred with such shares of Common Stock, (y) are not exercisable and (z) are also issued in respect of future issuances
of shares of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Price under this Section 12.3(d) will be
required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to
purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at
a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of
the existing right or warrant without exercise by the holder thereof). Pursuant to rights issued under any Company shareholder rights plan, if holders of the Securities exercising the right of
conversion after the date the rights separate from the underlying Common Stock are not entitled to receive the rights that would otherwise be attributable to the shares of Common Stock received upon
conversion, the Conversion Price will be adjusted as though the rights were being distributed to holders of Common Stock on the date of such separation. If such an adjustment is made and the rights
are later redeemed, invalidated or terminated, then a corresponding reversing adjustment will be made to the Conversion Price on an equitable basis. 

        In
addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with
respect thereto, that resulted in an adjustment to the Conversion Price under this Section 12.3(d): 

        (A)  in
the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be
readjusted upon such final redemption or repurchase 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 repurchase price received by a holder of shares of Common Stock with respect to such 

54

 

rights
or warrants (assuming such holder had retained such rights or warrants), made to all holders of shares of Common Stock as of the date of such redemption or repurchase; and 

        (B)  in
the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and
warrants had never been issued. 

         (v)  For
purposes of this Section 12.3(d) and Sections 12.3(a), 12.3(b) and 12.3(c), any dividend or distribution to which this Section 12.3(d) is
applicable that also includes (x) shares of Common Stock, (y) a subdivision or combination of shares of Common Stock to which Section 12.3(b) applies or (z) rights or
warrants to subscribe for or purchase shares of Common Stock or securities convertible into or
exercisable or exchangeable for Common Stock to which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be: 

        (A)  a
dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such
subdivision or combination or such rights or warrants or securities convertible into or exercisable or exchangeable for Common Stock to which Sections 12.3(a), 12.3(b) and 12.3(c) apply,
respectively (and any Conversion Price reduction required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by 

        (B)  a
dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants or securities convertible into or exercisable or
exchangeable for Common Stock (and any further Conversion Price reduction required by Sections 12.3(a), 12.3(b) and 12.3(c) with respect to such dividend or distribution shall then be made), except: 

        (1)   the
Record Date of such dividend or distribution shall be substituted as (x) "the date fixed for the determination of stockholders entitled to receive such
dividend or other distribution," "Record Date fixed for such determinations" and "Record Date" within the meaning of Section 12.3(a), (y) "the day upon which such subdivision becomes
effective" and "the day upon which such combination becomes effective" within the meaning of Section 12.3(b), and (z) as "the date fixed for the determination of stockholders entitled to
receive such rights or warrants," "the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants" and such "Record Date" within the meaning of
Section 12.3(c); and 

        (2)   any
shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination"
within the meaning of Section 12.3(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection
with such dividend or distribution. 

        (e)   In
case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all holders of its
shares of Common Stock, Cash (excluding any Cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which
Section 12.4 applies or as part of a distribution referred to in Section 12.3(d)), in an aggregate amount that, combined together with: 

          (i)  the
aggregate amount of any other such distributions to all holders of shares of Common Stock made exclusively in Cash within the 12 months preceding the date of
payment of such distribution, and in respect of which no adjustment pursuant to this Section 12.3(e) has been made; and 

55

 

         (ii)  the
aggregate amount of any Cash, plus the Fair Market Value, as of the expiration of any tender offer, of any other consideration paid in respect of any tender offer
by the Company or any of its Subsidiaries for all or any portion of the shares of Common Stock concluded within the 12 months preceding the date of such distribution; 

exceeds
15% of the product of (x) the Sale Price of the Common Stock on the date immediately prior to the Record Date with respect to such distribution, multiplied by (y) the number of
shares of Common Stock outstanding on such date (such excess over 15%, the "Excess Amount"), then, and in each case, immediately after the close of
business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business
of such Record Date by a fraction: 

        (A)  the
numerator of which shall be equal to the Current Market Price on the Record Date, less an amount equal to the quotient of (y) the Excess Amount and
(z) the number of shares of Common Stock outstanding on the Record Date; and 

        (B)  the
denominator of which shall be equal to the Current Market Price on such date. 

        (f)    For
purposes of this Article XII, the following terms shall have the meanings indicated: 

        "Current Market Price" on any date means the average of the daily Sale Prices per share of Common Stock for the ten consecutive Trading
Days immediately prior to such date; provided, however, that if: 

          (i)  the
"ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion
Price pursuant to Section 12.3(a), (b), (c), (d) of (e) occurs during such ten consecutive Trading Days, the Sale Price for each Trading Day prior to the "ex" date for such other event shall be
adjusted by multiplying such Sale Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event; 

         (ii)  the
"ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to
Section 12.3(a), (b), (c), (d) or (e) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Sale Price for each
Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Sale Price by the fraction by which the Conversion Price is so required to be adjusted as a result of
such other event; and 

        (iii)  the
"ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant
to clause (i) or (ii) of this proviso, the Sale Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any Cash and the Fair Market Value
(determined in a manner consistent with the method of determination of value for purposes of Section 12.3(d) or (e)) of the evidences of Indebtedness, shares of capital stock or assets being
distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. 

        For
purposes of this paragraph, the term "ex" date, when used: 

          (i)  with
respect to any issuance or distribution, means the first date on which the shares of Common Stock trade regular way on the relevant exchange or in the relevant
market from which the Sale Price was obtained without the right to receive such issuance or distribution; 

56

 

         (ii)  with
respect to any subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or
in such market after the time at which such subdivision or combination becomes effective; and 

        (iii)  with
respect to any tender or exchange offer, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the
expiration of such offer. 

Notwithstanding
the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.3, such adjustments shall be made to the Current Market Price
as may be necessary or appropriate to effectuate the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 

        "Fair Market Value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction (as determined
in good faith by the Board of Directors, whose good faith determination shall be conclusive). 

        "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of shares of
Common Stock have the right to receive any Cash, securities or other property or in which the shares of Common Stock (or other applicable security) is exchanged for or converted into any combination
of Cash, securities or other property, the date fixed for determination of stockholders entitled to receive such Cash, securities or other property (whether such date is fixed by the Board of
Directors or by statute, contract or otherwise). 

        (g)   The
Company shall be entitled at its election to make such additional reductions in the Conversion Price, in addition to those required by Sections 12.3(a), (b),
(c), (d) and (e), as shall be necessary in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of shares of Common Stock or any issuance of rights
or warrants referred to above shall not be taxable to the holders of Common Stock for United States federal income tax purposes. 

        (h)   To
the extent permitted by applicable law, the Company may, from time to time, reduce the Conversion Price by any amount for any period of time, if such period is at
least 20 days, the Board of Directors determines that the reduction in the Conversion Price is in the best interest of the Company, and the reduction is irrevocable during the period. Whenever
the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the Securities
maintained by the Registrar, at least 15 days prior to the date the reduced Conversion Price takes effect, a notice of the reduction stating the reduced Conversion Price and the period during
which it will be in effect. 

        (i)    In
any case in which this Section 12.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date, the Company
may elect to defer (but only for five Trading Days following the filing of the statement referred to in Section 12.5) issuing to the Holder of any Securities converted after such Record Date
the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Price prior to adjustment;  provided, however, that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder's right to receive
such additional shares upon the occurrence of the event requiring such adjustment. 

        (j)    All
calculations under this Section 12.3 shall be made to the nearest cent or one-hundredth of a share, with one-half cent and 0.005 of a
share, respectively, being rounded 

57

 

upward.
Notwithstanding any other provision of this Section 12.3, the Company shall not be required to make any adjustment of the Conversion Price unless such adjustment would require an
increase or decrease of at least 1% of such price. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with
any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% in such price. Any adjustments under this Section 12.3 shall be made successively
whenever an event requiring such an adjustment occurs. 

        (k)   In
the event that at any time, as a result of an adjustment made pursuant to this Section 12.3, the Holder of any Securities thereafter surrendered for conversion
shall become entitled to receive any shares of stock of the Company other than shares of Common Stock into which the Securities originally were convertible, the Conversion Price of such other shares
so receivable upon conversion of any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to
Common Stock contained in subparagraphs (a) through (j) of this Section 12.3, and the provision of Sections 12.1, 12.2 and 12.4 through 12.9 with respect to the Common
Stock shall apply on like or similar terms to any such other shares and the good faith determination of the Board of Directors as to any such adjustment shall be conclusive. 

        (l)    No
adjustment shall be made pursuant to this Section 12.3 (i) if the effect thereof would be to reduce the Conversion Price below the par value (if any) of
the Common Stock or (ii) if the Holders of the Securities may participate in the transaction that would otherwise give rise to an adjustment pursuant to this Section 12.3. 

        Section 12.4.    Consolidation or Merger of the Company.    

        If
any of the following events occurs, namely: 

        (a)   any
reclassification or change of the outstanding Common Stock into another class of Capital Stock (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or combination); 

        (b)   any
merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which all of the holders of Common Stock shall
be entitled to receive stock,
securities or other property or assets (including Cash or any combination thereof) with respect to or in exchange for all of their Common Stock; or 

        (c)   any
sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other person as a result of which all of the holders of
Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or any combination thereof) with respect to or in exchange for all of their Common Stock; 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, if such supplemental indenture is then required to so comply) providing that the Holder's right to convert a Security into Common Stock shall be changed to a
right to convert a Security into the kind and amount of shares of stock and other securities or property or assets (including Cash) which such Holder would have been entitled to receive upon such
reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such
reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to
the kind or amount of securities, Cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance
(provided, that if the kind or amount of securities, Cash or other property receivable upon such merger, consolidation, 

58

 

statutory
share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised
("Non-Electing Share"), then for the purposes of this Section 12.4, the kind and amount of securities, Cash or other property
receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a
plurality of the Non-Electing Shares). 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 XII. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and
assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be,
in such reclassification, change, merger, consolidation, statutory 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. 

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

        The
above provisions of this Section 12.4 shall similarly apply to successive reclassifications, changes, mergers, consolidations, statutory share exchanges, combinations, sales
and conveyances. 

        If
this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply. 

        Section 12.5.    Notice of Adjustment.    

        Whenever
an adjustment in the Conversion Price with respect to the Securities is required: 

        (a)   the
Company shall forthwith place on file with the Trustee and any Conversion Agent for such securities a certificate of the Treasurer of the Company, stating the
adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and 

        (b)   a
notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 14.2 hereof. Any notice so given shall be conclusively presumed to have
been duly given, whether or not the Holder receives such notice. 

        Section 12.6.    Notice in Certain Events.    

        In
case: 

        (a)   of
a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or conveyance to
another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under
the Exchange Act) of all or substantially all of the property and assets of the Company; or 

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

59

  

        (c)   of
any action triggering an adjustment of the Conversion Price referred to in clauses (y) or (z) below; 

then,
in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the manner provided in
Section 14.2 hereof, at least 15 days prior to the applicable date hereinafter specified, a notice stating: 

        (y)   the
date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants or other securities triggering an adjustment to the
Conversion Price pursuant to this Article XII, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants
or other securities are to be determined, or 

        (z)   the
date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up described under clauses (a), (b) and (c)
of Section 12.4 that changes a Holder's right to convert into Common Stock to a right to convert into another kind and amount of securities or other property or assets is expected to become
effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger sale, conveyance, dissolution, liquidation or winding up. 

        Failure
to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in clause (a), (b) or (c) of this Section 12.6. 

        Section 12.7.    Company To Reserve Stock: Registration; Listing.    

        (a)   The
Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock for the purpose of
effecting the conversion of the Securities, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all Securities then
outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder). The Company
covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided
in Section 12.8, taxes with respect to the issue thereof. 

        (b)   If
any shares of Common Stock which would be issuable upon conversion of Securities hereunder require registration with or approval of any governmental authority before
such shares or securities may be issued upon such conversion, the Company will use its commercially reasonable efforts to cause such shares or securities to be duly registered or approved, as the case
may be. The Company further covenants that so long as the Common Stock shall be listed on the NYSE, the Company will use its commercially reasonable efforts, if permitted by the rules of the NYSE, to
list and keep listed all Common Stock issuable upon conversion of the Securities, and the Company will use its commercially reasonable efforts to list the shares of Common Stock required to be
delivered upon conversion of the Securities prior to such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery. 

        Section 12.8.    Taxes on Conversion.    

        The
issue of stock certificates on conversion of Securities shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect
of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on
conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which 

60

 

may
be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock or the portion, if any, of the Securities which are not so converted in a name other than that in
which the Securities so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of such tax or has
established to the satisfaction of the Company that such tax has been paid. 

        The
Company agrees, and each Holder is deemed to agree, that delivery to such Holder of the full number of shares of Common Stock into which each Security is convertible, together with
any Cash payment of such Holder's fractional shares or otherwise in accordance with Section 12.13, will be treated as a contingent payment (in an amount equal to the sum of the then Fair Market
Value of such Common Stock and such Cash payment, if any) on the Securities for purposes of the Contingent Payment Debt Regulations governing contingent payment debt obligations. 

        Nothing
contained herein shall preclude any income tax withholding required by law or regulation upon conversion of the Securities, and at the Company's request, Holders shall be
responsible for satisfying any such withholding. 

        Section 12.9.    Conversion After Record Date.    

        Except
as provided in this Section 12.9, a converting Holder of Securities shall not be entitled to receive any accrued and unpaid interest (including Contingent Interest, if any)
on any such Securities being converted. By delivery to the Holder of the number of shares of Common Stock or other consideration issuable or payable upon conversion in accordance with this
Article XII, any accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, on such Securities will be deemed to have been paid in full. If any
Securities are surrendered for conversion subsequent to the Record Date preceding an Interest Payment Date but prior to such Interest Payment Date, the Holder of such Securities at the close of
business on such Record Date shall receive the interest payable on such Security on such Interest Payment Date notwithstanding the conversion thereof. Securities surrendered for conversion during the
period from the close of business on any Record Date preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of Securities which have
been called for redemption on a Redemption Date within such period) be accompanied by payment from converting Holders, for the account of the Company, in New York Clearing House funds, or other funds
of an amount equal to the interest payable on such Interest Payment Date on the Securities being surrendered for conversion; provided,  however, if the
Company elects to redeem Securities on a date that is after the Regular Record Date but prior to the corresponding Interest Payment
Date, and such Holder elects to convert those Securities, the Holder will not be required to pay the Company, at the time that Holder surrenders those Securities for conversion, the amount of interest
such Holder will have received on the Interest Payment Date. 

        Except
as provided in this Section 12.9, no adjustments in respect of payments of interest, including Contingent Interest, if any, and Additional Amounts, if any, on Securities
surrendered for conversion or any dividends or distributions or interest on the Common Stock issued upon conversion shall be made upon the conversion of any Securities. 

        Section 12.10.    Company Determination Final.    

        Any
determination that the Company or the Board of Directors must make pursuant to this Article XII shall be conclusive if made in good faith and in accordance with the provisions
of this Article, absent manifest error, and set forth in a Board Resolution. 

        Section 12.11.    Responsibility of Trustee for Conversion Provisions.    

        The
Trustee has no duty to determine when an adjustment under this Article XII should be made, how it should be made or what it should be. The Trustee makes no representation as
to the validity or 

61

 

value
of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of the Company to comply with this Article XII. Each Conversion
Agent other than the Company shall have the same protection under this Section 12.11 as the Trustee. 

        The
rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture including, without limitation, its rights to be indemnified, are extended to, and
shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder. 

        Section 12.12.    Unconditional Right of Holders to Convert.    

        Notwithstanding
any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to convert its Security in accordance with
this Article XII and to bring an action for the enforcement of any such right to convert, and such rights shall not be impaired or affected without the consent of such Holder. 

 
 

ARTICLE XIII    
    
    TAX TREATMENT    
    

        Section 13.1.    Tax Treatment.    

        (a)   The
parties hereto hereby agree, and each Holder and any beneficial holder of a Security by its purchase of a Security hereby agrees (in the absence of administrative
pronouncement or judicial ruling to the contrary): 

          (i)  to
treat the Securities as indebtedness of the Company for all United States federal income tax purposes; 

         (ii)  to
treat the Securities as debt instruments that are subject to Treasury Regulation section 1.1275-4(b); and 

        (iii)  to
treat the delivery of Common Stock or Cash (including Cash delivered in lieu of a fractional share) to a Holder of a Security upon conversion of such Security, or
upon a purchase of such Security
by the Company at the option of the Holder of a Security where the Company makes a payment in Cash (including Cash paid in lieu of a fractional share) or elects to pay in Common Stock or Applicable
Stock, as applicable, as a contingent payment (in an amount equal to the sum of the Fair Market Value of such Common Stock and any Cash received) under Treasury Regulation
section 1.1275-4(b). 

        Section 13.2.    Comparable Yield and Projected Payment Schedule.    

        (a)   Solely
for purposes of applying Treasury Regulation section 1.1275-4 to the Securities: 

          (i)  for
United States federal income tax purposes, the Company shall accrue interest with respect to outstanding Securities as original issue discount according to the
"noncontingent bond method," as set forth in Treasury Regulation section 1.1275-4(b) using a comparable yield of 8.20%, compounded semiannually, and the projected payment schedule
referred to below; 

         (ii)  the
Company shall file with the Trustee promptly at the end of each calendar year (A) a written notice specifying the amount of original issue discount for
United States federal income tax purposes accrued on outstanding Securities as of the end of such year and (B) such other specific information relating to such original issue discount that the
Company determines to be relevant under the Internal Revenue Code of 1986, as amended from time to time, including the amount of any adjustment made under the noncontingent bond method to account for
the amount of any difference between the amount of an actual payment and the amount of a projected payment; and 

62

 

        (iii)  the
Company acknowledges and agrees, and each Holder and any beneficial holder of a Security, by its purchase of a Security shall be deemed to acknowledge and agree,
that (A) the comparable yield and the projected payment schedule are determined on the basis of an assumption of linear growth of stock price and a constant growth in dividend yield,
(B) the comparable yield and the projected payment schedule are not determined for any purpose other than for the purpose of applying Treasury Regulation
section 1.1275-4(b)(4) to the Security, (C) the comparable yield and the projected payment schedule do not constitute a projection or representation regarding the actual
amounts payable on the Securities, and (D) the Company's application of Treasury Regulation section 1.1275-4(b) shall be binding on each Holder and any beneficial holder of a
Security, including the Company's determination of the comparable yield and the projected payment schedule. A Holder of Securities may obtain the amount of original issue discount, issue date, yield
to maturity, comparable yield and projected payment schedule by submitting a written request for it to the Trustee at the Trustee's address specified in Section 14.2. The Company, upon the
request of the Trustee, shall provide to the Trustee the amount of original issue discount, issue date, yield to maturity, comparable yield and projected payment schedule.

[FORM OF REVERSE OF SECURITY]    
    
    3.375% Convertible Senior Notes due 2023    

        This
Security is one of a duly authorized issue of 3.375% Convertible Senior Notes due 2023 (the "Securities") of HILTON HOTELS CORPORATION, a Delaware corporation (including any
successor corporation under the Indenture hereinafter referred to, the "Company"), issued under an Indenture, dated as of April 22, 2003 (the "Indenture"), between the Company and BNY WESTERN
TRUST COMPANY, 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 referred to below unless otherwise indicated. 

1.    Interest.    

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

        In
addition, the Company shall pay contingent interest ("Contingent Interest") to the Holders during any six-month period (a
"Contingent Interest Period") from April 15 to October 14 and from October 15 to April 14, commencing with the
six-month period beginning April 15, 2008, if the average Market Price of a Security for the five Trading Day period ending on the third Trading Day immediately preceding the
relevant Contingent Interest Period equals $1,200 (120% of the principal amount of a Security) or more. 

        Upon
a determination by the Company that Holders will be entitled to receive Contingent Interest which will become payable during a Contingent Interest Period, on or prior to the first
day of such Contingent Interest Period, the Company shall deliver an Officer's Certificate to the Trustee setting
forth the amount of such Contingent Interest per $1,000 principal amount of Securities and shall issue a press release through a public medium as is customary for such a press release. 

        The
amount of Contingent Interest payable per $1,000 principal amount of Securities in respect of any Contingent Interest Period shall equal 0.41% per annum. Contingent Interest, if any,
will accrue and be payable to Holders in the same manner as regular Cash interest. Regular Cash interest will continue to accrue at the rate of 3.375% per year on the principal amount of the
Securities whether or not Contingent Interest is paid. 

        If
this Security is redeemed pursuant to Section 5 of this Security or the Holder elects to require the Company to repurchase this Security pursuant to Section 6 of this
Security, on a date that is after the Regular Record Date and prior to the corresponding Interest Payment Date, interest (including Contingent Interest, if any) and Additional Amounts, if any, accrued
and unpaid hereon to, but not including, the applicable Redemption Date, Repurchase Date or Fundamental Change Repurchase Date will be paid to the same Holder to whom the Company pays the principal of
such Security regardless of whether such Holder was the registered Holder on the Regular Record Date immediately preceding the applicable Redemption Date, Repurchase Date or Fundamental Change
Repurchase Date. 

        Interest
(including Contingent Interest, if any) and Additional Amounts, if any, on Securities converted after the close of business on a Regular Record Date but prior to the opening of
business on the corresponding Interest Payment Date will be paid to the Holder of the Securities on the Regular Record Date but, upon conversion, the Holder must pay the Company the interest
(including 

A-6

 

Contingent
Interest, if any) and Additional Amounts, if any, which has accrued and will be paid on such Interest Payment Date. No such payment need be made with respect to Securities which will be
converted after a Regular Record Date and prior to the corresponding Interest Payment Date after being called for redemption by the Company. 

        Any
reference herein to interest accrued or payable as of any date shall include any Additional Amounts accrued or payable on such date as provided in the Registration Rights Agreement. 

2.    Method of Payment.    

        Payment
of the principal of and interest (including Contingent Interest, if any) and Additional Amounts, if any, on the Securities shall be in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and private debts or in Common Stock or Applicable Stock, as the case may be, as permitted in the Indenture. The Holder must
surrender the
Securities to the Paying Agent to collect payment of principal. Payment of interest (including Contingent Interest, if any) and Additional Amounts, if any, on Certificated Securities will be made by
check mailed to the address of the Person entitled thereto as such address appears in the Register. Notwithstanding the foregoing, so long as the Securities are registered in the name of a Depositary
or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

3.    Paying Agent, Registrar, Conversion Agent and Bid Solicitation Agent.    

        Initially,
BNY Western Trust Company will act as Paying Agent, Conversion Agent and Bid Solicitation Agent. The Company may appoint and change any Paying Agent, Registrar, Conversion
Agent or Bid Solicitation Agent without notice, other than notice to the Trustee; provided that the Company will maintain at least one Paying Agent in the State of New York, The City of New York,
Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Registrar or Conversion
Agent. None of the Company or any Subsidiary or any Affiliate of any of them may act as Bid Solicitation Agent. 

4.    Indenture.    

        The
Securities are general unsecured obligations of the Company limited to up to $575,000,000 aggregate principal amount. The Indenture does not limit other indebtedness of the Company,
secured or unsecured. 

5.    Redemption at the Option of the Company.    

        The
Company may, at its option, redeem the Securities for Cash at any time as a whole, or from time to time in part, on or after April 15, 2008, at a redemption price equal to
100% of the principal amount of Securities to be redeemed plus any accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, on those Securities to, but not
including, the Redemption Date (the "Redemption Price"). 

        Notice
of redemption pursuant to this Section of this Security will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of
Securities to be redeemed at the Holder's registered address. If Cash sufficient to pay the Redemption Price of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited
with the Paying Agent prior to 10:00 a.m., New York City time, on the Redemption Date, then on such Redemption Date interest (including Contingent Interest, if any) and Additional Amounts, if
any cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of principal amount may be redeemed in part but only in integral multiples of $1,000 of
principal amount. 

A-7

 

6.    Repurchase By the Company at the Option of the Holder or Upon a Fundamental Change.    

        Subject
to the terms and conditions of the Indenture, the Company shall become obligated to repurchase, at the option of the Holder, all or any portion of the Securities held by such
Holder on April 15, 2008, April 15, 2013 and April 15, 2018 in integral multiples of $1,000 at a repurchase price equal to 100% of the principal amount of those Securities plus
accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, to, but not including, such Repurchase Date (the "Repurchase
Price"). To exercise such right, a Holder shall deliver to the Paying Agent a Repurchase Notice containing the information set forth in the Indenture, at any time from
9:00 a.m., New York City time, on the date that is 20 Business Days immediately preceding such Repurchase Date until 5:00 p.m., New York City time, on the Business Day immediately
preceding such Repurchase Date, and shall deliver the Securities to the Paying Agent as set forth in the Indenture. 

        If
the Securities are to be repurchased on April 15, 2008, the Repurchase Price must be paid in Cash. If the Securities are to be repurchased on April 15, 2013 or
April 15, 2018 Repurchase Date, the Repurchase Price may be paid, at the option of the Company, in Cash or by the issuance and delivery of shares of Common Stock, or in any combination thereof,
subject to the terms and conditions of the Indenture. 

        Subject
to the terms and conditions of the Indenture, the Company shall become obligated to repurchase, at the option of the Holder, all or any portion of the Securities held by such
Holder upon a Fundamental Change of the Company that occurs prior to April 15, 2008 in integral multiples of $1,000 at the Fundamental Change Repurchase Price. 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 prior to 5:00 p.m., New York City time, 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. 

        The
Fundamental Change Repurchase Price may be paid, at the option of the Company, in Cash or by the issuance and delivery of shares of Applicable Stock, or in any combination thereof,
subject to the terms and conditions of the Indenture. 

        Holders
have the right to withdraw any Repurchase Notice or 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, Common Stock and/or Applicable Stock, as applicable, if permitted under the Indenture, sufficient to pay the Repurchase Price or Fundamental Change Repurchase Price, as the case
may be, of all Securities or portions thereof to be repurchased with respect to a Repurchase Date or Fundamental Change Repurchase Date, as the case may be, has been deposited with the Paying Agent,
at 10:00 a.m., New York City time, on the Business Day immediately following the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, then, immediately after the
Repurchase Date or Fundamental Change Repurchase Date, as applicable, such Securities will cease to be outstanding and interest (including Contingent Interest, if any) and Additional Amounts, if any,
on such Securities will cease to accrue and the Holder thereof shall have no other rights as such other than the right to receive the Repurchase Price or Fundamental Change Repurchase Price upon
surrender of such Security. 

7.    Conversion.    

        Subject
to and in compliance with the provisions of the Indenture (including, without limitation, the conditions to conversion of this Security set forth in Section 12.1 and
Section 12.2 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
$1,000), into, subject to Section 12.12(e) of the Indenture, under which a Holder converting its Security in a Principal Value Conversion shall 

A-8

 

receive,
in lieu of a number of shares of Common Stock based on the Conversion Price, Cash or Common Stock or a combination of Cash and Common Stock, at the Company's sole option, with a value equal
to the principal amount of the Security so surrendered for conversion, fully paid and nonassessable of shares of Common Stock at the Conversion Price in effect on the date of conversion. 

        The
Company will notify Holders of any event triggering the right to convert the Securities as specified above in accordance with the Indenture. 

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

        The
initial Conversion Price is $22.50, subject to adjustment in certain events described in the Indenture. 

        To
surrender a Security for conversion, a Holder must, in the case of Global Securities, comply with the Applicable Procedures of the Depositary in effect at that time, and in the case
of Certificated Securities, (1) surrender the Security to the Conversion Agent, (2) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of
such notice) and deliver such notice to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents and (4) pay all funds required, if any, relating to interest
(including Contingent Interest, if any) or Additional Amounts, if any, and any withholding, transfer or similar tax, if required. 

        No
fractional share of Common Stock shall be issued upon conversion of any Security. Instead, the Company shall pay a Cash adjustment as provided in the Indenture. 

        No
payment or adjustment will be made for accrued and unpaid interest (including Contingent Interest, if any) and Additional Amounts, if any, or dividends on the shares of Common Stock,
except as provided in the Indenture. 

        If
the Company (i) is a party to a consolidation, merger, statutory share exchange or combination of the Company with another corporation and as a result of which all the holders
of the outstanding Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or a combination thereof) with respect to or in exchange for all of their
Common Stock, (ii) reclassifies or changes the shares of the outstanding Common Stock into another class of Capital Stock (other than a change in par value or from par value to no par value, or
from no par value to par value, or as a result of a subdivision or combinations) or (iii) conveys or sells its properties and assets as, or substantially as, an entirety to any person and as a
result of which all the holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or a combination thereof) with respect to or in exchange for
all of their Common Stock, the right to convert a Security into shares of Common Stock shall be changed into a right to convert into the kind and amount of shares of stock and other securities or
property or assets (including Cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or
conveyance had such Holder converted its Security into Common Stock immediately prior to such transaction, in each case, in accordance with the Indenture. 

8.    Denominations; Transfer; Exchange.    

        The
Securities are in fully registered form, without coupons, in denominations of $1,000 of 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 selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to 

A-9

 

be
redeemed) or any Securities in respect of which a Repurchase Notice or Fundamental Change Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be repurchased in
part, the portion of the Security not to be repurchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 

9.    Persons Deemed Owners.    

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

10.    Unclaimed Money or Securities.    

        The
Trustee and the Paying Agent shall return to the Company upon written request any Cash 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 unclaimed 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. 

11.    Amendment; Waiver.    

        Subject
to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent or affirmative vote of the Holders of not
less than a majority in aggregate principal amount of the outstanding Securities and (ii) certain Defaults may be waived with the written consent or affirmative vote of the Holders of not less
than a majority in aggregate principal amount of the outstanding Securities. 

        Without
the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to (i) add to the covenants of the Company for the benefit of the
Holders of Securities, (ii) surrender any right or power conferred upon the Company in the Indenture, (iii) provide for the assumption of the Company's obligations to the Holders of
Securities in the case of a merger, consolidation, conveyance, transfer, sale, lease or other disposition pursuant to Article VII of the Indenture, (iv) increase the Conversion Rate or
reduce the Conversion Price; provided, however, that such increase in the Conversion Rate or reduction in the Conversion Price is in accordance with the
terms of the Indenture or shall not adversely affect the interest of the Holders of Securities in any material respect, (v) comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA, (vi) provide for a successor Trustee with respect to the Securities, (vii) add any additional Events of Default with respect to
all or any of the Securities, (viii) secure the Securities, (ix) supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the
discharge of the Securities, provided that such change or modification does not adversely affect the interests of the Holders of the Securities in any material respect, (x) make any changes or
modifications necessary in connection with the registration of the Securities under the Securities Act as contemplated in the Registration Rights Agreement; provided,
however, that such action pursuant to this clause does not adversely affect the interests of the Holders of Securities in any material respect, (xi) cure any ambiguity,
correct or supplement any provision in the Indenture which may be inconsistent with any other provision therein or which is otherwise defective, or to make any other provisions with respect to matters
or questions arising under the Indenture which the Company may deem necessary or desirable and which shall not be inconsistent with the provisions of the Indenture; provided,
however, that such action pursuant to this clause does not adversely affect the interests of the Holders of Securities in any material respect, and (xii) add or modify
any other provisions in the Indenture with respect to matters or questions arising thereunder which the Company and the Trustee may deem necessary or desirable and which would not reasonably be
expected to adversely affect the interests of the Holders of Securities in any material respect. 

A-10

 

12.    Defaults and Remedies.    

        If
any Event of Default other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company or its Significant Subsidiaries occurs and is continuing, the
principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy,
insolvency or reorganization of the Company or its Significant Subsidiaries, the principal of all the Securities shall become due and payable immediately without any declaration or other act on the
part of the Trustee or any Holder, all as and to the extent provided in the Indenture. 

13.    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 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. 

14.    Calculations in Respect of Securities.    

        The
Company or its agents will be responsible for making all calculations called for under the Securities including, but not limited to, determination of the Market Price and Sale Price
of the Common Stock or Applicable Stock, as applicable, the number of shares of Common Stock or Applicable Stock, as applicable, and (if applicable, the amount of Cash) issuable or payable upon
conversion and the amounts of interest and Additional Amounts, if any, on the Securities. Any calculations made in good faith and without manifest error will be final and binding on Holders of the
Securities. The Company or its agents will be required to deliver to the Trustee a schedule of its calculations and the Trustee will be entitled to conclusively rely upon the accuracy of such
calculations without independent verification. 

15.    No Recourse Against Others.    

        No
recourse under or upon any obligation, covenant or agreement contained in the Indenture, or in this Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such, or against any past, present or future stockholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities by the Holders and as part of the consideration for the issue of the Securities. 

16.    Authentication.

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.

the information requested pursuant to this Section. No Holder of Registrable Securities shall be entitled to Additional Amounts pursuant to Section 3 hereof unless such Holder has properly
completed and delivered to the Company the Questionnaire prior to the Questionnaire Deadline and has delivered to the Company in writing prior to the Information Request Deadline any other information
that the Company may reasonably request for use in connection with the Shelf Registration Statement or Prospectus or Preliminary Prospectus included therein and in any application to be filed with or
under state securities laws. Each Holder as to which the Shelf Registration Statement is being effected agrees to furnish promptly in writing to the Company all information required to be disclosed in
order to make information previously furnished to the Company by such Holder not materially misleading. 

        3.    ADDITIONAL AMOUNTS.    

        (a)   If:

        (i)    the
Shelf Registration Statement has not been filed with the Commission prior to or on the Shelf Filing Deadline, 

        (ii)   the
Shelf Registration Statement has not been declared effective by the Commission prior to or on the Effectiveness Target Date, 

        (iii)  subject
to the provisions of Section 4(b)(i) hereof, the Shelf Registration Statement is filed and declared effective but, during the Effectiveness
Period and after the Effectiveness Target Date, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within five Business Days by a
post-effective amendment to the Shelf Registration Statement, a prospectus supplement or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
Exchange Act that cures such failure and, in the case of a post-effective amendment, is itself declared effective within such five Business Day period, or 

        (iv)  the
Company suspends the Holders' use of the Prospectus for more than 120 days in the aggregate, 

        (each
such event referred to in foregoing clauses (i) through (iv), a "Registration Default"), then, subject to the penultimate sentence of Section 2(b) hereof, the Company
hereby agrees to pay additional amounts ("Additional Amounts") to each Holder from and including the day following the Registration Default to but excluding the earlier of (x) the day on which
the Registration Default has been cured or (y) the date the Shelf Registration Statement is no longer required to be kept effective, accruing at a rate: 

        (A)  with
respect to such Holder's Convertible Notes, for the first 90-day period during which a Registration Default shall have occurred and be continuing, an
amount equal to 0.25% per annum on the principal amount of such Holder's Convertible Notes, increasing to an amount per annum on the principal amount of such Holder's Convertible Notes equal to 0.50%
on the 91st day during which such Registration Default shall have occurred and is continuing, provided that in 

4

 

no
event shall the Additional Amounts pursuant to this clause accrue at a rate per annum exceeding 0.50% of the principal amount of such Holder's Convertible Notes; 

        (B)  with
respect to such Holder's Common Stock issued upon conversion of such Holder's Convertible Notes, for the first 90-day period during which a Registration
Default shall have occurred and be continuing, an amount equal to 0.25% per annum on the principal amount of such Holder's converted Convertible Notes, increasing to an amount per annum on the
principal amount of such Holder's converted Convertible Notes equal to 0.50% on the 91st day during which such Registration Default shall have occurred and is continuing, provided that in no event
shall the Additional Amounts pursuant to this clause accrue at a rate per annum exceeding 0.50% of the principal amount of such Holder's converted Convertible Notes; 

        (b)   All
accrued Additional Amounts shall be paid in arrears to Record Holders by the Company on each Additional Amounts Payment Date by wire transfer of immediately
available funds or by federal funds check. Following the cure of all Registration Defaults relating to any particular Convertible Note or share of Common Stock, the accrual of Additional Amounts with
respect to such Convertible Note or share of Common Stock will cease. 

        All
obligations of the Company set forth in this Section 3 that are outstanding with respect to any Registrable Security at the time such Registrable Security ceases to be a
Registrable Security shall survive until such time as all such obligations with respect to such Registrable Security shall have been satisfied in full. 

        The
Additional Amounts set forth above shall be the exclusive monetary remedy available to the Holders of Registrable Securities for such Registration Default. 

        4.    REGISTRATION PROCEDURES.    

        (a)   In
connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 4(b) hereof and shall, in accordance with
Section 2 hereof, prepare and file with the Commission a Shelf Registration Statement relating to the registration on any appropriate form under the Securities Act. 

        (b)   In
connection with the Shelf Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Registrable Securities, the Company
shall: 

        (i)    Subject
to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described in
Section 4(b)(iii)(D), use its reasonable efforts to keep the Shelf Registration Statement continuously effective during the Effectiveness Period; upon the occurrence of any event that would
cause the Shelf Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Registrable
Securities during the Effectiveness Period, the Company shall file promptly an appropriate amendment to the Shelf Registration Statement, a prospectus supplement or a report filed with the Commission
pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A)
or (B), use its reasonable efforts to cause such amendment to be declared effective and the Shelf Registration Statement and the related Prospectus to become usable for their intended purposes as soon
as practicable thereafter. Notwithstanding the foregoing, the Company may, by written notice to the Holders, suspend the Holders' use of the Prospectus from time to time for up to an aggregate of
120 days during the Effectiveness Period (each such period, a "Suspension Period") if: 

        (x)   the
Shelf Registration Statement is not usable solely because a post-effective amendment to such Shelf Registration Statement to incorporate financial
information with respect to the Company or any of its subsidiaries is not yet effective and needs to be declared effective to permit Holders to use the related Prospectus; or 

5

 

        (y)   an
event occurs and is continuing as a result of which the Shelf Registration Statement would, in the Company's reasonable judgment, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company reasonably determines that the disclosure of
such event at such time would have a material adverse effect on the business of the Company and its subsidiaries, taken as a whole or would cause the premature disclosure of or impede the Company's
ability to consummate a proposed material transaction; 

provided, that each Holder, by its acceptance of a Registrable Security, agrees to hold in confidence any communication by the Company relating to an
event described in Section 4(b)(i)(y) or Section 4(b)(iii)(D). The Company shall not be required to specify in the written notice to the Holders the nature of the event giving rise to
the Suspension Period. 

        (ii)   Prepare
and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be necessary to keep the Shelf
Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to
Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of
the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during the applicable period in accordance with the intended method or methods of
distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the Prospectus. 

        (iii)  Advise
the selling Holders promptly and, if requested by such Persons, to confirm such advice in writing: 

        (A)  when
the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any
post-effective amendment thereto, when the same has become effective; 

        (B)  of
any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the Prospectus or for additional information relating
thereto; 

        (C)  of
the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any
state securities commission of the qualification of the Registrable Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes; or 

        (D)  of
the existence of any fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the Shelf Registration
Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf
Registration Statement or the Prospectus in order to make the statements therein not misleading. 

        If
at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory
authority shall issue an order suspending the qualification or exemption from qualification of the Registrable Securities under state securities or Blue Sky laws, the Company shall use its reasonable
efforts to obtain the withdrawal or lifting of such order at the earliest possible time. 

        (iv)  Furnish
to one counsel for the selling Holders before filing with the Commission, a copy of the Shelf Registration Statement and copies of any Prospectus included
therein or any amendments or supplements to either of the Shelf Registration Statement or Prospectus (other 

6

 

than
documents incorporated by reference after the initial filing of the Shelf Registration Statement), which documents will be subject to the review of such counsel for a period of two Business Days,
and the Company will not file the Shelf Registration Statement or Prospectus or any amendment or supplement to the Shelf Registration Statement or Prospectus (other than documents incorporated by
reference) to which such counsel shall reasonably object within two Business Days after the receipt thereof. 

        (v)   Subject
to the execution of a confidentiality agreement reasonably acceptable to the Company, make available at reasonable times for inspection by one or more
representatives of the selling Holders, designated in writing by a Majority of Holders whose Registrable Securities are included in the Shelf Registration Statement, and any attorney or accountant
retained by the Majority of Holders, all financial and other records, pertinent corporate documents and properties of the Company as shall be reasonably necessary to enable them to exercise any
applicable due diligence responsibilities, and cause the Company's officers, directors, managers and employees to supply all information reasonably requested by any such representative or
representatives of the selling Holders, attorney or accountant in connection with the Shelf Registration Statement after the filing thereof and before its effectiveness;  provided, however, that any
information designated by the Company as confidential at the time of delivery of such information shall be kept confidential
by the recipient thereof. 

        (vi)  If
reasonably requested by any selling Holders, incorporate in the Shelf Registration Statement or Prospectus, pursuant to a supplement or post-effective
amendment if necessary, such information as such selling Holders shall, on the basis of an opinion of a nationally recognized counsel experienced in such matters, determine to be required to be
included therein by applicable law, including, without limitation: (1) information relating to the "Plan of Distribution" of the Registrable Securities, (2) information with respect to
the principal amount of Convertible Notes or number of shares of Common Stock being sold, (3) the purchase price being paid therefor and (4) any other terms of the offering of the
Registrable Securities to be sold in such offering; provided, however, that with respect to any information requested for inclusion by a selling Holder,
this clause (vi) shall apply only to information that relates to the Registrable Securities to be sold by such selling Holder; and make all required filings of such Prospectus supplement or
post-effective amendment as soon as reasonably practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective
amendment. 

        (vii) Furnish
to each selling Holder without charge, at least one copy of the Shelf Registration Statement, as first filed with the Commission, and of each amendment thereto
specifically naming such selling Holder (and any documents incorporated by reference therein or exhibits thereto (or exhibits incorporated in such exhibits by reference) as such Person may request in
writing). 

        (viii) Deliver
to each selling Holder without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto
specifically naming such selling Holder as such Persons reasonably may request; subject to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event
of the kind described in Section 4(b)(iii)(D), the Company hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders in connection with
the offering and the sale of the Registrable Securities covered by the Prospectus or any amendment or supplement thereto. 

        (ix)  Before
any public offering of Registrable Securities, cooperate with the selling Holders, and their counsel in connection with the registration and qualification of the
Registrable Securities under the securities or Blue Sky laws of such jurisdictions as the selling Holders may reasonably request and do any and all other acts or things reasonably necessary or
advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the Shelf Registration 

7

 

Statement;  provided, however, that the Company shall not be required (A) to register or qualify as a foreign corporation or a dealer of
securities where it is not now so qualified or to take any action that would subject it to the service of process in any jurisdiction where it is not now so subject or (B) to subject itself to
taxation in any such jurisdiction if it is not now so subject. 

        (x)   Cooperate
with the selling Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any
restrictive legends (unless required by applicable securities laws); and enable such Registrable Securities to be in such denominations and
registered in such names as the Holders may reasonably request at least three Business Days before any sale of Registrable Securities. 

        (xi)  Use
its reasonable efforts to cause the Registrable Securities covered by the Shelf Registration Statement to be registered with or approved by such other U.S.
governmental agencies or authorities as may be required by applicable law to enable the seller or sellers thereof to consummate the disposition of such Registrable Securities, subject to the proviso
in clause (ix) above. 

        (xii) Subject
to Section 4(b)(i) hereof, if any fact or event contemplated by Section 4(b)(iii)(D) hereof shall exist or have occurred, use its
reasonable efforts to prepare a supplement or post-effective amendment to the Shelf Registration Statement or related Prospectus or any document incorporated therein by reference or file
any other required document so that, as thereafter delivered to the purchasers of Registrable Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they made, not misleading. 

        (xiii) Provide
CUSIP numbers for all Registrable Securities not later than the effective date of the Shelf Registration Statement and provide the Trustee under the Indenture
with certificates for the Convertible Notes that are in a form eligible for deposit with The Depository Trust Company. 

        (xiv) Cooperate
and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation that is required to be retained in
accordance with the rules and regulations of the NASD. 

       (xv)  Otherwise
use its reasonable efforts to comply with all applicable rules and regulations of the Commission and all reporting requirements under the Exchange Act. 

      (xvi)  Cause
the Indenture to be qualified under the TIA not later than the effective date of the Shelf Registration Statement required by this Agreement, and, in connection
therewith, cooperate with the Trustee and the holders of Convertible Notes to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms
of the TIA; and execute and use its reasonable efforts to cause the Trustee thereunder to execute all documents that may be required to effect such changes and all other forms and documents required
to be filed with the Commission to enable such Indenture to be so qualified in a timely manner. 

     (xvii)  Cause
all Registrable Securities covered by the Shelf Registration Statement to be listed or quoted, as the case may be, on each securities exchange or automated
quotation system on which securities issued by the Company of the same series are then listed or quoted, it being understood that the Convertible Notes will not be so listed or quoted and nothing
herein shall require the Company to effect any such listing or quotation of the Convertible Notes. 

8

  

    (xviii)  During
the time the Shelf Registration Statement is effective, excluding any Suspension Period, provide promptly to a Holder upon its written request each document
filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act after the effective date of the Shelf Registration Statement, unless such
documents are available from EDGAR; provided, however, that the Company shall not be required to deliver to such Holder (i) any material for
which the Company has sought (provided that it subsequently receives) confidential treatment by the SEC, (ii) any correspondence with the SEC or (iii) any material relating to
shareholder proposals. 

        (c)   Each
Holder agrees by acquisition of a Registrable Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in
Section 4(b)(iii)(D) hereof, such Holder will, forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until: 

          (i)  such
Holder has received copies of the supplemented or amended Prospectus contemplated by Section 4(b)(xiii) hereof; or 

         (ii)  such
Holder is notified in writing by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus, unless such filings are available on EDGAR. 

        If
so directed by the Company, each Holder will deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the
Prospectus covering such Registrable Securities that was current at the time of receipt of such notice of suspension. 

        (d)   Each
Holder who intends to be named as a selling Holder in the Shelf Registration Statement shall properly complete and deliver to the Company the Questionnaire prior to
the Questionnaire Deadline, which shall include such information regarding such Holder and the proposed distribution by such Holder of its Registrable Securities for use by the Company in connection
with the Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Holders that do not properly complete the Questionnaire and deliver it to the Company prior to the
Questionnaire Deadline shall not be eligible to be named as selling securityholders in the Prospectus or preliminary Prospectus included in the Shelf Registration Statement and therefore shall not be
permitted to sell any Registrable Securities pursuant to the Shelf Registration Statement. In addition, each Holder who intends to be named as a selling Holder in the Shelf Registration Statement
shall promptly furnish to the Company in writing all information required to be disclosed in order to make information previously furnished to the Company by such Holder not materially misleading, and
such other information prior to the Information Request Deadline as the Company may from time to time reasonably request in writing. 

        5.    REGISTRATION EXPENSES.    

        (a)   Subject
to Section 5(b) below, all expenses incident to the Company's performance of or compliance with this Agreement shall be borne by the Company regardless of
whether a Shelf Registration Statement becomes effective, including, without limitation: 

          (i)  all
registration and filing fees and expenses (other than filings made by any Initial Purchasers or Holders with the NASD); 

         (ii)  all
fees and expenses of compliance with federal securities and state Blue Sky or securities laws; 

        (iii)  all
expenses of printing (including printing of Prospectuses and certificates for the shares of Common Stock to be issued upon conversion of the Convertible Notes),
messenger and delivery services, and telephone; 

9

 

        (iv)  all
fees and disbursements of counsel to the Company and, subject to Section 5(b) below, the Holders of Registrable Securities; 

         (v)  all
application and filing fees in connection with listing of (or authorizing for quotation of) the shares of Common Stock on a national securities exchange or automated
quotation system pursuant to the requirements hereof; and 

        (vi)  all
fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or
incident to such performance). 

        The
Company shall bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal, accounting or other duties), the
expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 

        (b)   In
connection with the Shelf Registration Statement required by this Agreement, the Company shall reimburse the Initial Purchasers and the Holders of Registrable
Securities being registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel; such counsel shall be Skadden, Arps,
Slate, Meagher & Flom LLP or such other counsel chosen by a Majority of Holders for whose benefit the Shelf Registration Statement is being prepared and is reasonably acceptable to the Company.
The Company shall not be required to pay any underwriter discount, commission or similar fees related to the sale of the Registrable Securities. 

        6.    INDEMNIFICATION AND CONTRIBUTION.    

        (a)   The
Company shall indemnify and hold harmless each Holder, such Holder's directors and officers, and each person, if any, who controls such Holder within the meaning of
Section 15 of the Securities Act (each, an "Indemnified Holder"), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not
limited to, any loss, claim, damage, liability or action relating to resales of the Registrable Securities), to which such Indemnified Holder may become subject, under the Securities Act or otherwise,
insofar as any such loss, claim, damage, liability or action arises out of, or is based upon: 

          (i)  any
untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or Prospectus or any amendment or supplement thereto;
or 

         (ii)  the
omission or alleged omission to state in the Shelf Registration Statement any material fact required to be stated therein or necessary to make the statements
therein not misleading, or the omission or alleged omission to state in the Prospectus any material fact required to be stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; 

and
shall reimburse each Indemnified Holder promptly upon demand for any legal or other expenses, subject to Section 6(c) below, reasonably incurred by such Indemnified Holder in connection
with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, (A) any untrue statement or alleged untrue statement or omission or
alleged omission made in the Shelf Registration Statement or Prospectus or amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by or on
behalf of any Holder (or its related Indemnified Holder) specifically for use therein or (B) the failure by the Holder or Indemnified Holder to deliver to any purchaser of its Registrable
Securities the Prospectus and any supplement or amendment thereto in the form provided to such Holder or Indemnified Holder by the Company if such 

10

 

Holder
is required to so deliver pursuant to the prospectus delivery requirements of the Securities Act; provided,  further, that as to any preliminary Prospectus,
this indemnity agreement shall not inure to the benefit of any Indemnified Holder or any officer,
employee, representative, agent, director or controlling person of that Indemnified Holder on account of any loss, claim, damage, liability or action arising from the sale of the Registrable
Securities sold pursuant to the Shelf Registration Statement to any person by such Indemnified Holder if (i) that Indemnified Holder failed to send or give a copy of the Prospectus, as the same
may be amended or supplemented, to that person within the time required by the Securities Act and (ii) the untrue statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact in such preliminary Prospectus was corrected in the Prospectus or a supplement or amendment thereto, as the case may be, unless in each case, such failure resulted
from noncompliance by the Company with Section 4. The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to any Indemnified Holder. 

        (b)   Each
Holder, severally and not jointly, shall indemnify and hold harmless the Company, its directors and officers, and each person, if any, who controls the Company
within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company or any such officer, employee, representative, agent or controlling person may become subject, under the Securities Act or otherwise insofar as any such loss,
claim, damage or liability or action arises out of, or is based upon: 

          (i)  any
untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or Prospectus or any amendment or supplement
thereto; or 

         (ii)  the
omission or the alleged omission to state in the Shelf Registration Statement any material fact required to be stated therein or necessary to make the statements
therein not misleading, or the omission or alleged omission to state in the Prospectus any material fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; 

but
in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder (or its related Indemnified Holder) specifically for use therein, and shall reimburse the Company and any such director, officer, employee,
representative, agent or controlling person promptly upon demand for any legal or other expenses, subject to Section 6(c) below, reasonably incurred by the Company and any such director,
officer, employee, representative, agent or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such
expenses are incurred. The foregoing indemnity agreement is in addition to any liability that any Holder may otherwise have to the Company and any such director, officer, employee or controlling
person. 

        (c)   Promptly
after receipt by an indemnified party under this Section 6 of notice of any claim or the commencement of any action, the indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the commencement of that action;  provided,
however, that the failure to notify the indemnifying party shall not relieve it from any
liability that it may have under this Section 6 except to the extent it has been materially prejudiced by such failure and, provided,  further, that
the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise
than under this Section 6. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified 

11

 

indemnifying
party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided,  however, that the indemnified party shall
have the right to employ counsel to represent jointly the indemnified party and its respective directors,
employees, officers and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party
under this Section 6 if such indemnified party shall have been advised in writing that the representation of such indemnified party and those directors, employees, officers and controlling
persons by the same counsel would be inappropriate under applicable standards of professional conduct due to actual or potential differing interests between them, and in that event the reasonable fees
and expenses of one separate counsel shall be paid by the indemnifying party. It is understood that the indemnifying party shall not be liable for the reasonable fees and expenses of more than one
separate firm (in addition to local counsel in each jurisdiction) for all indemnified parties in connection with any proceeding or related proceedings. Each indemnified party, as a condition of the
indemnity agreements contained in Sections 6(a) and 6(b), shall use its reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party
shall: 

          (i)  without
the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) effect any settlement of any pending or threatened
action in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such
settlement, compromise or consent includes an
unconditional release of such indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to or an admission of fault, culpability or
failure to act by or on behalf of any indemnified party, or 

         (ii)  be
liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability
by reason of such settlement or judgment in accordance with this Section 6. 

        (d)   If
the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the registration of the Registrable Securities pursuant to the Shelf Registration, or (ii) if the allocation provided by the foregoing clause (i) is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying
party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party,
as the case may be, on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified
party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with 

12

 

investigating
or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 6(d), the Holders of the Registrable
Securities shall not be required to contribute any amount in excess of the amount by which the gross proceeds received by such Holders from the sale of the Registrable Securities pursuant to the Shelf
Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company. 

        (e)   The
indemnity and contribution provisions contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser, any Holder or any person controlling any Initial Purchaser or any Holder, or by or on behalf of the
Company, its officers or directors or any person controlling the Company, and (iii) any sale of Registrable Securities pursuant to the Shelf Registration Statement. 

        7.    RULE 144A.    

        In
the event the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each Holder, for so long as any Registrable Securities remain
outstanding and are "restricted securities" within the meaning of Rule 144 under the Securities Act, to make available, upon request, to any Holder or beneficial owner of Registrable Securities
in connection with any sale thereof and any prospective purchaser of such Registrable Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Registrable Securities pursuant to Rule 144A. 

        8.    MISCELLANEOUS.    

        (a)    Remedies.    The Company acknowledges and agrees that any failure by the Company to comply with its obligations
under Section 2 hereof may result in material irreparable injury to the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Section 2 hereof. The Company
further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. 

        (b)    No Inconsistent Agreements.    The Company will not, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. 

        (c)    Amendments and Waivers.    This Agreement may not be amended, modified or supplemented, and waivers or consents
to or departures from the provisions hereof may not be given, unless the Company has obtained the written consent of a Majority of Holders. 

        (d)    Notices.    All notices and other communications provided for or permitted hereunder shall be made in writing
by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery:

guaranteeing overnight delivery. 

Copies
of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee or the transfer agent, as applicable, at the address specified
in the Indenture. 

A
document or notice shall be deemed to have been furnished to the Holders of the Registrable Securities if it is provided to the registered holders of the Registrable Securities at the address set
forth in clause (i) above. 

        (e)    Successors and Assigns.    This Agreement shall inure to the benefit of and be binding upon the successors,
assigns and transferees of each of the parties, including without limitation and without the need for an express assignment, subsequent Holders of Registrable Securities;  provided, however, that (i) nothing contained herein shall be deemed to permit any assignment,
transfer or other disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture and (ii) this Agreement shall not inure to the benefit of or be
binding upon a successor or assign of a Holder unless and to the extent such successor or assign acquired Registrable Securities from such Holder. The Initial Purchasers (in their capacity as Initial
Purchasers) shall have no liability or obligation to the Company with respect to any failure by a 

14

 

Holder
to comply with, or breach by any Holder of, any of the obligations of such Holder under this Agreement. 

        (f)    Purchases and Sales of Convertible Notes.    During the period of two years after the date hereof, the Company
shall not, and shall not permit any of its affiliates (as defined in Rule 144 under the Securities Act), to resell any of the Convertible Notes which constitute "restricted securities" under
Rule 144 that have been reacquired by any of them. 

        (g)    Third Party Beneficiaries.    The Holders shall be third-party beneficiaries to the agreements made hereunder
between the Company and the Initial Purchasers, and such Initial Purchasers, so long as
they are also Holders, shall have the right to enforce such agreements directly to the extent they deem such enforcement necessary or advisable to protect their rights or the rights of Holders
hereunder. 

        (h)    Counterparts.    This Agreement may be executed in any number of counterparts and by the parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

        (i)    Securities Held by the Company or its Affiliates.    Whenever the consent or approval of Holders of a specified
percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its affiliates (as such term is defined in Rule 405 under the Securities Act) shall not
