ARTICLE 2
  
    THE SECURITIES    
  

Section 2.1.  Form and Dating  

    The
Securities and the Trustee's certificate of authentication shall be substantially in the respective forms set forth in  Exhibit A, which Exhibit is incorporated in and made part of this Indenture.
The Securities may have notations, legends or endorsements required
by law, stock exchange or marketplace rule or usage. Each Security shall be dated the date of its authentication. The Securities are being 

7

 

offered and sold by the Company pursuant to a Purchase Agreement, dated July 30, 2001 (the "Purchase Agreement"), between the Company and the
Initial Purchaser. 

    (a)  Global Securities.  Each Global Security shall represent such of the outstanding Securities as shall
be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, purchases or conversions of such Securities. Any endorsement of a
Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Securities Custodian in accordance with the standing
instructions and procedures existing between the Depositary and the Securities Custodian. 

    The
Global Securities shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the
depositary, The Depository Trust Company ("DTC") (such depositary, or any successor thereto, being hereinafter referred to as the
"Depositary"), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as
hereinafter provided. The aggregate principal amount of the Global Security may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian as
hereinafter provided, subject in each case to compliance with the Applicable Procedures. 

    Members
of, or participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary or under any Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of
the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the
Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

    (b)  Certificated Securities.  Certificated Securities shall be issued only under the limited
circumstances provided in Section 2.12(a)(1) hereof. 

Section 2.2.  Execution and Authentication  

    An
Officer shall sign the Securities for the Company by manual or facsimile signature attested by the manual or facsimile signature of the Secretary or an Assistant Secretary of the
Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security which has been authenticated and delivered by the
Trustee. 

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

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

    The
Trustee shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $150 million (plus up to an additional
$25 million in aggregate principal amount issuable upon the exercise by the Initial Purchaser of the over-allotment option described in the Purchase Agreement) upon receipt of a
written order or orders of the Company signed by two Officers of the Company (a "Company Order"). The Company Order shall specify the amount of
Securities to be authenticated, shall provide that all such Securities will be represented by a 

8

 

Global Security and the date on which each original issue of Securities is to be authenticated. The aggregate principal amount of Securities outstanding at any time may not exceed $175,000,000, except
as provided in Section 2.7. 

    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. An
authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 

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

Section 2.3.  Registrar, Paying Agent and Conversion Agent  

    The
Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a
"Registrar"), one or more offices or agencies where Securities may be presented for payment (each, a "Paying
Agent"), one or more offices or agencies where Securities may be presented for conversion (each, a "Conversion Agent") and one
or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent,
Conversion Agent,
Registrar 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, the City of New York. One
of the Registrars (the "Primary Registrar") shall keep a register of the Securities and of their transfer and exchange. 

    The
Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. 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 Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or
agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may
act as Paying Agent (except for the purposes of Section 6.1 and Article 10). 

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

Section 2.4.  Paying Agent to Hold Money in Trust  

    Prior
to 11:00 a.m., New York City time, on each due date of the principal of or interest, if any, on any Securities, the Company shall deposit with a Paying Agent a sum
sufficient to pay such principal or interest, if any, so becoming due. A Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the
payment of principal of or interest, if any, on the Securities, and shall notify the Trustee of any default by the Company (or any other obligor on the Securities) in making any such payment. If the
Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of or interest on any Securities, segregate the
money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any
default, upon written request to a Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than
the Company) shall have no further liability for the money. 

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 Primary 

9

 

Registrar, the Company shall furnish 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 a Registrar with a request to
register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange
as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in form satisfactory to the Registrar duly executed by the Holder
thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency
maintained pursuant to Section 2.3, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar's request. Any exchange or
transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto, and provided, that this sentence shall not apply to any exchange pursuant to Section 2.7, 2.10, 2.12(a)(1), 3.6, 3.11, 4.2 (last
paragraph) or 11.5. 

    Neither
the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of (1) any Securities for a period of 15 days next preceding any
mailing of a notice of Securities to be redeemed, (2) any Securities or portions thereof selected or called for redemption (except, in the case of redemption of a Security in part, the portion
not to be redeemed) or (3) any Securities or portions thereof in respect of which a Change in Control Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the
case of the purchase of a Security in part, the portion not to be purchased). 

    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 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with
the delivery by such Registrar of Securities upon transfer or exchange of Securities. 

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

10

  

Section 2.7.  Replacement Securities  

    If
any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a 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 applicable Registrar and the Trustee such Security or indemnity as will be required by them to save each of them
harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its written
request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal
amount, bearing a 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 or purchased by the Company pursuant to
Article 3, the Company in its discretion may, instead of issuing a new Security, pay, redeem or purchase 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 or other governmental charge that may
be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 

    Every
new Security issued pursuant to this Section 2.7 in lieu of any 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 (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities. 

Section 2.8.  Outstanding Securities  

    Securities
deemed to be outstanding at any time include only those Securities authenticated by the Trustee, except for those canceled by it, those delivered to it for cancellation and
those described in this Section 2.8 as not outstanding. 

    If
a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona
fide purchaser. 

    If
a Paying Agent (other than the Company or an Affiliate of the Company) holds on a redemption date, a Change in Control Purchase Date or the Final Maturity Date money sufficient to
pay the principal of (including premium, if any) and accrued interest on Securities (or portions thereof) payable on that date, then on and after that date such Securities (or portions thereof, as the
case may be) cease to be outstanding and interest on them ceases to accrue. 

    Subject
to the restrictions contained in Section 2.9, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 

Section 2.9.  Treasury Securities  

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

11

 

owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so
to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 

Section 2.10.  Temporary Securities  

    Until
definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary
Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations
that the Company, with the consent of the Trustee, considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver
definitive Securities in exchange for temporary Securities. 

Section 2.11.  Cancellation  

    The
Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any
Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for
transfer, exchange, redemption, payment, conversion or cancellation and shall deliver the canceled Securities to the Company. All Securities which are redeemed, purchased or otherwise acquired by the
Company or any of its Subsidiaries prior to the Final Maturity Date shall be delivered to the Trustee for cancellation and the Company may not hold or resell such Securities or issue any new
Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 4. Without limitation to the foregoing, any Securities acquired by any investment
bankers or other purchasers pursuant to Section 3.7 shall be surrendered for conversion and thereafter cancelled, and may not be reoffered, sold or otherwise transferred. 

Section 2.12.  Additional Transfer and Exchange Requirements  

    (a)  Transfer and Exchange of Global Securities.  

    (1) 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, or (y) 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 delivery 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 names such Securities are so registered. Such exchange
shall be effected in accordance with the Applicable Procedures. 

    (2) Notwithstanding
any other provisions of this Indenture other than the provisions set forth in Section 2.12(a)(1), a Global Security may not be transferred as
a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or 

12

 

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)(1) of this Indenture, on or after such event when Certificated Securities are presented by a
Holder to a Registrar with a request: 

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

    (2) 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(a); and 

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

    (i)  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); 

    (ii) if
such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in accordance with Rule 144A or is being
transferred to a Non-U.S. Person in an offshore transaction in accordance with Rule 904 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 

    (iii) if
such Restricted Certificated Security is being transferred (A) pursuant to an exemption from the registration requirements of the Securities Act in
accordance with Rule 144 or (B) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144 or
Rule 904) and as a result of which, in the case of a Security transferred pursuant to this clause (b), such Security shall cease to be a "restricted security" within the meaning of
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 such Registrar so requests, a customary opinion
of counsel, certificates and other information reasonably acceptable to the Company and such Registrar to the effect that such transfer is in compliance with the registration requirements of the
Securities Act. 

    (c)  Transfer of a Beneficial Interest 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 a beneficial interest in 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 

13

 

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): 

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

    (2) if
such beneficial interest is being transferred (i) pursuant to an exemption from the registration requirements of the Securities Act in accordance with
Rule 144 or (ii) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144, or Rule 904) and as a
result of which, in the case of a Security transferred pursuant to this clause (ii), such Security shall cease to be a "restricted security" within the meaning of Rule 144, a
certification to that effect from the transferor (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 Trustee to the effect that such transfer is in compliance with the registration requirements of the Securities Act. 

The
Trustee, as a Registrar and Custodian, 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, 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 an Unrestricted Global Security and, 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) and a certification from the transferor in substantially the form set forth in the Transfer Certificate. The Trustee, as a Registrar and Custodian, 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)(1) 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 for interests in Global Securities by complying
with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances 

14

 

requiring that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request: 

    (1) 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 

    (2) 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 Notes and Unrestricted
Certificated Securities may be exchanged only for Unrestricted Global Notes), 

the
Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing, or directing the Securities Custodian to cause, 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 authenticate and deliver a new
Global Security; provided, however, that the Certificated Securities presented or surrendered for registration 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(a); 

    (ii) 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 (A) an exemption from the registration requirements of the Securities Act in
accordance with Rule 144 or (B) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144, or
Rule 904) and as a result of which, in the case of a Security transferred pursuant to this clause (B), such Security shall cease to be a "restricted security" within the meaning of
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 Trustee to the effect that such transfer is in compliance with the registration requirements of the
Securities Act; 

    (iii) 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 or is being transferred to a Non-U.S. Person in
an offshore transaction in accordance with Rule 904; 

    (iv) 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 

15

 

    (v) 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 or is being transferred to a Non-U.S. Person in
an offshore transaction in accordance with Rule 904. 

    (f)  Legends.  

    (1) Except
as permitted by the following paragraphs (2) and (3), 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  hereto (each a "Restricted Global Security" for so long
as it is required by this Indenture to bear such legend). Each Restricted Global Security shall have attached thereto a
certificate (a "Transfer Certificate") in substantially the form attached hereto as Exhibit C. 

    (2) Upon
any sale or transfer of a Restricted Global Security (w) after the expiration of the holding period applicable to sales of the Securities under
Rule 144(k) of the Securities Act, (x) pursuant to Rule 144, (y) pursuant to an effective registration statement under the Securities Act or (z) pursuant to any
other available exemption (other than Rule 144A) from the registration requirements of the Securities Act and as a result of which, in the case of a Security transferred pursuant to this
clause (z), such Security shall cease to be a "restricted security" within the meaning of Rule 144: 

    (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, that such Unrestricted Global Security shall continue to be subject to the provisions of Section 2.12(a)(2); 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 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 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. 

    (g)  Transfers to the Company.  Nothing 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 

16

 

Company or any of its Subsidiaries, which Securities shall thereupon be cancelled in accordance with Section 2.11. 

Section 2.13.  CUSIP Numbers  

    The
Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption or purchase as a
convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice
of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or purchase 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 3
  
    REDEMPTION AND PURCHASES    
  

Section 3.1.  Notice to Trustee  

    If
the Company elects to redeem Securities pursuant to the provisional or optional redemption provisions of Section 3.7 hereof, it shall notify the Trustee at least
20 days and not more than 60 days prior to the redemption date as fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), of the redemption date and the
principal amount of Securities to be redeemed. If fewer than all of the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the
Trustee, which record date shall not be less than ten days after the date of notice to the Trustee. 

Section 3.2.  Selection of Securities to be Redeemed  

    If
less than all of the Securities are to be redeemed, the Trustee shall, not more than 60 days prior to the redemption date, select the Securities to be redeemed. The Trustee
shall make the selection from the Securities outstanding and not previously called for redemption, by lot, or in its discretion, on a pro rata basis. Securities in denominations of $1,000 may only be
redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 or any multiple thereof) of the principal of Securities that have denominations larger than $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. 

    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 to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee
as outstanding for the purpose of such selection. 

Section 3.3. Notice of Redemption  

    (a) At
least 20 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption to each
Holder of Securities to be redeemed at such Holder's address as it appears on the Primary Registrar's books. 

    The
notice shall identify the Securities (including CUSIP numbers) to be redeemed and shall state: 

    (1) the
Redemption Date; 

    (2) the
Redemption Price; 

    (3) the
then-current Conversion Price; 

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

17

 

    (5) that Securities called for redemption must be presented and surrendered to a Paying Agent to collect the redemption price; 

    (6) that
Holders who wish to convert Securities must surrender such Securities for conversion no later than the close of business on the Business Day immediately
preceding the redemption date and must satisfy the other requirements in paragraph 8 of the Securities; 

    (7) that,
unless the Company defaults in making the redemption payment, interest on Securities called for redemption shall cease accruing on and after the redemption
date and the only remaining right of the Holder shall be to receive payment of the redemption price, plus accrued interest, if any upon presentation and surrender to a Paying Agent of the Securities;
and 

    (8) if
any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date, upon
presentation and surrender of such Security, a new Security or Securities in aggregate principal amount equal to the unredeemed portion thereof will be issued. 

    (b) If
any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the
procedures of the Depositary applicable to redemptions. At the Company's written request, which request shall (1) be irrevocable once given and
(2) set forth all relevant information required by clauses (1) through (8) of paragraph (a) above, the Trustee shall give the notice of redemption in the Company's name and
at the Company's expense. 

Section 3.4.  Effect of Notice Redemption  

    Once
notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, together with
accrued interest, if any, except for Securities that are converted in accordance with the provisions of Article 4. Upon presentation and surrender to a Paying Agent, Securities called for
redemption shall be paid at the redemption price, plus accrued interest up to but not including the redemption date; provided if the redemption date is an interest payment date, interest will be
payable to the Holders in whose names the Securities are registered at the close of business on the relevant record dates for payment of such interest. 

Section 3.5.  Deposit of Redemption Price  

    The
Company, prior to 11:00 a.m. New York City time, on the Redemption Date, shall deposit with a Paying Agent (or, if the Company or an Affiliate of the Company acts as Paying
Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date, other than Securities or portions thereof
called for redemption on that date which have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall return to the Company any money not required
for that purpose because of the conversion of Securities pursuant to Article 4 or, if such money is then held by the Company in trust and is not required for such purpose, it shall be
discharged from the trust. 

Section 3.6.  Securities Redeemed in Part  

    Upon
presentation and surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security equal in
principal amount to the unredeemed portion of the Security surrendered. 

Section 3.7.  Provisional and Optional Redemption  

    (a)  Optional Redemption.  The Securities may be redeemed at the election of the Company, as a whole or
from time to time in part, at any time on or after August 20, 2004, on at least 20 and no more than 60 days' notice at the redemption prices specified in paragraph 5 of the form
of Security 

18

 

attached hereto as Exhibit A, together with accrued interest and Additional Interest, if any, up to but not including the Redemption Date;
provided that if the Redemption Date is an interest payment date, interest will be payable to the Holders in whose name the Securities are registered at the close of business on the relevant record
dates for payment of such interest. 

    (b)  Provisional Redemption.  The Securities may be redeemed at the election of the Company, as a whole
or in part, from time to time prior to August 20, 2004 (a "Provisional Redemption"), upon at least 20 and not more than 60 days' notice by
mail to the Holders of the Securities at a redemption price equal to $1,000 per $1,000 principal amount of the Securities redeemed plus accrued and unpaid interest and Additional Interest thereon, if
any, to but excluding the date of redemption (the "Provisional Redemption Date"), if any, (such amount, together with the Make-Whole Payment
described below, the "Provisional Redemption Price"), if (1) the Closing Sale Price of the Common Stock has exceeded 150% of the Conversion Price
for at least 20 Trading Days within a period of any 30 consecutive Trading Days ending on the Trading Day prior to the date of the mailing of the notice of Provisional Redemption (the
"Notice Date"), and (2) a shelf registration statement covering resales of the Securities and the Common Stock issuable upon conversion thereof
is effective and available for use and is expected to remain effective and available for use for the 30 days following the Provisional Redemption Date unless registration is no longer required;
provided that if the Redemption Date is an interest payment date, interest will be payable to the Holders in whose name the Securities are registered at the close of business on the relevant record
dates for payment of such interest. 

    Upon
any such Provisional Redemption, the Company shall make an additional payment, at its option, in cash or Common Stock or a combination of cash and Common Stock (the
"Make-Whole Payment") with respect to the Securities called for redemption to Holders on the Notice Date in an amount equal to $166.83 per
$1,000 principal amount of the Securities, less the amount of any interest actually paid (including, if the Provisional Redemption Date occurs after a record date but before an interest payment date,
any interest paid or to be paid in connection with such interest payment date) on such Securities on or prior to the Provisional Redemption Date. Payments made in Common Stock will be valued at 97% of
the average of the closing sales prices of Common Stock for the five Trading Days ending on the day prior to the Provisional Redemption Date. The Company shall make the Make-Whole Payment
on all Securities called for Provisional Redemption, including those Securities converted into Common Stock between the Notice Date and the Provisional Redemption Date. 

    (c) Any
redemption pursuant to this Section 3.7 shall be made pursuant to the provisions of Section 3.1 through 3.6 hereof. 

    (d) In
connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement
with one or more investment bankers or other purchasers to purchase such Securities by paying to a Paying Agent (other than the Company or any of its Affiliates) in trust for the Holders, on or before
11:00 a.m. New York City time on the applicable Redemption Date, an amount that, together with any amounts deposited with such Paying Agent by the Company for the redemption of such Securities,
is not less than the applicable
Redemption Price, together with interest accrued to, but not including, the applicable Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article 3,
the obligation of the Company to pay the applicable Redemption Price of such Securities, including all accrued interest, shall be deemed to be satisfied and discharged to the extent such amount is so
paid by such purchasers; provided, however, that nothing in this Section 3.7 shall relieve the Company of its obligation to pay the applicable
Redemption Price, plus accrued interest to but excluding the relevant redemption date, on Securities called for redemption. If such an agreement with one or more investment banks or other purchasers
is entered into, any Securities called for redemption and not surrendered for conversion by the Holders thereof prior to the relevant redemption date may, at the option of the Company upon written
notice to the Trustee, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary 

19

 

contained in Article 4) surrendered by such purchasers for conversion, all as of 11:00 a.m. New York City time on the applicable Redemption Date, subject to payment of the above amount
as aforesaid. The Paying Agent shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase in the same manner as it would money deposited
with it by the Company for the redemption of Securities. Without the Paying Agent's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any
Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the
Paying Agent from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the
Company and such purchasers, including the costs and expenses incurred by the Paying Agent in the defense of any claim or liability arising out of or in connection with the exercise or performance of
any of its powers, duties, responsibilities or obligations under this Indenture. 

Section 3.8.  Purchase of Securities at Option of the Holder Upon Change in Control  

    (a) If
at any time that Securities remain outstanding there shall occur a Change in Control, Securities shall be purchased by the Company at the option of the Holders
thereof as of the date that is 30 Business Days after the occurrence of the Change in Control (the "Change in Control Purchase Date") at a purchase
price equal to the principal amount of the Securities, plus accrued and unpaid interest to, but excluding, the Change in Control Purchase Date (the "Change in Control Purchase
Price"), subject to satisfaction by or on behalf of any Holder of the requirements set forth in subsection (c) of this Section 3.8. 

    A
"Change in Control" shall be deemed to have occurred if any of the following occurs after the date hereof: 

    (1) any
"person" or "group" (as such terms are defined below) (other
than as a direct result of repurchases of stock by the Company or its subsidiaries) is or becomes the "beneficial owner" (as
defined below), directly or indirectly, of shares of Voting Stock of the Company representing 50% or more of the total voting power of all outstanding classes of Voting Stock of the Company or has the
power, directly or indirectly, to elect a majority of the members of the Board of Directors of the Company; or 

    (2) the
Company consolidates with, or merges with or into, another Person or the Company sells, assigns, conveys, transfers, leases or otherwise disposes of all or
substantially all of the assets of the Company, or any Person consolidates with, or merges with or into, the Company, in any such event other than pursuant to a transaction in which the Persons that,
as a group, "beneficially owned" (as defined below), directly or indirectly, shares of Voting Stock of the Company immediately prior to such transaction, "beneficially own" (as defined below),
directly or indirectly, shares of Voting Stock of the surviving or transferee Person representing at least a majority of the total Voting Stock of the surviving or transferee Person; or 

    (3) there
shall occur the liquidation or dissolution of the Company. 

For
the purpose of the definition of "Change in Control," (i) "person" and "group" have the meanings given such terms under Section 13(d) and 14(d) of the Exchange Act or any successor
provision to either of the foregoing, and the term "group" includes any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of
Rule 13d-5(b)(1) under the Exchange Act (or any successor provision thereto), (ii) a "beneficial owner" shall be determined in accordance with Rule 13d-3
under the Exchange Act, as in effect on the date of this Indenture, except that the number of shares of Voting Stock of the Company shall be deemed to include, in addition to all outstanding shares of
Voting Stock of the Company and Unissued Shares deemed to be held by the "person" or "group" (as such terms are defined above) or other Person with respect to which the Change in 

20

 

Control determination is being made, all Unissued Shares deemed to be held by all other Persons and (iii) the terms "beneficially owned" and "beneficially own" shall have meanings correlative
to that of "beneficial owner." The term "Unissued Shares" means shares of Voting Stock not outstanding that are subject to options, warrants, rights to
purchase or conversion privileges exercisable within 60 days of the date of determination of a Change in Control. 

    Notwithstanding
anything to the contrary set forth in this Section 3.8, a Change in Control will not be deemed to have occurred if either: 

    (1) the
closing price (determined in accordance with Section 4.6(g) of this Indenture) of the Common Stock for any five Trading Days during the ten Trading Days
immediately preceding the Change in Control is at least equal to 105% of the Conversion Price in effect on such Trading Day; or 

    (2) in
the case of a merger or consolidation, all of the consideration excluding cash payments for fractional shares in the merger or consolidation constituting the
Change in Control consists of common stock traded on a United States national securities exchange or quoted on the Nasdaq National Market ("NNM"), or
which will be so traded or quoted when issued or exchanged in connection with such Change In Control and as a result of such transaction or transactions the Securities become convertible solely into
such common stock. 

    (b) Within
10 Business Days after the occurrence of a Change in Control, the Company shall mail a written notice of the Change in Control to the Trustee (and the Paying
Agent if the Trustee is not then acting as Paying Agent) and to each Holder (and to beneficial owners as required by applicable law). The notice shall include the form of a Change in Control Purchase
Notice to be completed by the Holder and shall state: 

    (1) the
date of such Change in Control and, briefly, the events causing such Change in Control; 

    (2) the
date by which the Change in Control Purchase Notice pursuant to this Section 3.8 must be given; 

    (3) the
Change in Control Purchase Date; 

    (4) the
Change in Control Purchase Price; 

    (5) briefly,
the conversion rights of the Securities; 

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

    (7) the
Conversion Price and any adjustments thereto; 

    (8) that
Securities as to which a Change in Control Purchase Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture
only to the extent that the Change in Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 

    (9) the
procedures that the Holder must follow to exercise rights under this Section 3.8; 

    (10) the
procedures for withdrawing a Change in Control Purchase Notice, including a form of notice of withdrawal; and 

    (11) that
the Holder must satisfy the requirements set forth in the Securities in order to convert the Securities. 

    If
any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary
applicable to the repurchase of Global Securities. 

21

  

    (c) A
Holder may exercise its rights specified in subsection (a) of this Section 3.8 upon delivery of a written notice (which shall be in substantially
the form included in Exhibit B hereto and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any
other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary's customary procedures) of the exercise of such rights (a
"Change in Control Purchase Notice") to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Change in
Control Purchase Date. 

    The
delivery of such Security to any Paying Agent (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of
the Change in Control Purchase Price therefor. 

    The
Company shall purchase from the Holder thereof, pursuant to this Section 3.8, a portion of a Security if the principal amount of such portion is $1,000 or an integral
multiple of $1,000. Provisions of the Indenture that apply to the purchase of all of a Security pursuant to Sections 3.8 through 3.13 also apply to the purchase of such portion of such Security. 

    Notwithstanding
anything herein to the contrary, any Holder delivering to a Paying Agent the Change in Control Purchase Notice contemplated by this subsection (c) shall have
the right to withdraw such Change in Control Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of
business on the Business Day next preceding the Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.9. 

    A
Paying Agent shall promptly notify the Company of the receipt by it of any Change in Control Purchase Notice or written withdrawal thereof. 

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

Section 3.9.  Effect of Change in Control Purchase Notice  

    Upon
receipt by any Paying Agent of the Change in Control Purchase Notice specified in Section 3.8(c), the Holder of the Security in respect of which such Change in Control
Purchase Notice was given shall (unless such Change in Control Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Change in Control Purchase Price with respect to
such Security. Such Change in Control Purchase Price shall be paid to such Holder promptly following the later of (a) the Change in Control Purchase Date with respect to such Security (provided
the conditions in Section 3.8(c) have been satisfied) and (b) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by
Section 3.8(c). Securities in respect of which a Change in Control Purchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock on or after the date of
the delivery of such Change in Control Purchase Notice unless such Change in Control Purchase Notice has first been validly withdrawn. 

    A
Change in Control Purchase Notice may be withdrawn by means of a written notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any
other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary's customary procedures) of withdrawal delivered by the
Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Change in Control Purchase Date, specifying the principal amount of the Security or
portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted. 

22

 

Section 3.10.  Deposit of Change in Control Purchase Price  

    On
or before 11:00 a.m. New York City time on the Change in Control Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent (other than the Company or
an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Change in Control Purchase Price of all the
Securities or portions thereof that are to be purchased as of such Change in Control Purchase Date and shall notify the Trustee or Paying Agent of such deposit. The manner in which the deposit
required by this Section 3.10 is made by the Company shall be at the option of the Company, provided that such deposit shall be made in a manner
such that the Trustee or a Paying Agent shall have immediately available funds on the Change in Control Purchase Date. 

    If
a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Change in Control Purchase Price of any Security for which a Change in Control Purchase
Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Change in Control Purchase Date, such Security will cease to be outstanding and the rights of the Holder in
respect thereof shall terminate (other than the right to receive the Change in Control Purchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities purchased as
a result of such Change in Control on or as soon as practicable after the Change in Control Purchase Date. 

Section 3.11.  Securities Purchased in Part  

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

Section 3.12.  Compliance with Securities Laws Upon Purchase of Securities  

    In
connection with any offer to purchase or purchase of Securities under Section 3.8, the Company shall (a) comply with Rule 13e-4 and
Rule 14e-1 (or any successor to either such Rule), if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or
report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to
permit the rights of the Holders and obligations of the Company under Sections 3.8 through 3.11 to be exercised in the time and in the manner specified therein. 

Section 3.13.  Repayment to the Company  

    To
the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.10 exceeds the aggregate Change in Control Purchase Price together with interest,
if any, thereon of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Change in Control Purchase Date the Trustee or a Paying Agent, as the case may
be, shall return any such excess cash to the Company. 

    Without
limiting the generality of any other provisions limiting the Trustee's duties hereunder, the Trustee shall have no duty or obligation to determine the Company's compliance
with Article 3 hereof.

ARTICLE 4
  
    CONVERSION    
  

Section 4.1.  Conversion Privilege  

    Subject
to the further provisions of this Section 4.1, a Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any
integral multiple of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the Business Day prior to the Final Maturity Date, at the Conversion Price then in
effect; provided, however, that, if such Security is called for redemption or submitted or presented for purchase pursuant to Article 3, such
conversion right shall terminate at the close of business on the Business Day immediately preceding the redemption date or Change in Control Purchase Date, as the case may be, for such Security or
such earlier date as the Holder presents such Security for redemption or for purchase (unless the Company shall default in making the redemption payment or Change in Control Purchase Price payment
when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Security is redeemed or purchased, as the case may be). The number of
shares of Common Stock issuable upon conversion of a Security shall be determined by dividing the principal amount of the Security or portion thereof surrendered for conversion by the Conversion Price
in effect on the Conversion Date. The initial Conversion Price is set forth in paragraph 8 of the Securities and is subject to adjustment as provided in this Article 4. 

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

    A
Security in respect of which a Holder has delivered a Change in Control Purchase Notice pursuant to Section 3.8(c) exercising the option of such Holder to require the Company
to purchase such Security may be converted only if such Change in Control Purchase Notice is withdrawn by a written notice of withdrawal delivered to a Paying Agent prior to the close of business on
the Business Day immediately preceding the Change in Control Purchase Date in accordance with Section 3.9. 

    A
Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities to Common Stock, and only to the extent such Securities
are deemed to have been converted into Common Stock pursuant to this Article 4. 

Section 4.2.  Conversion Procedure  

    To
convert a Security, a Holder must (a) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent,
(b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any
transfer or similar tax, if required. The date on which the Holder satisfies all of those requirements is the "Conversion Date." As soon as practicable
after the Conversion Date, the Company shall deliver to the Holder through a Conversion Agent a certificate for the number of whole shares of Common Stock issuable upon the conversion and cash in lieu
of any fractional shares pursuant to Section 4.3. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may
be surrendered for conversion in accordance with the Applicable Procedures as in effect from time to time. 

    The
person in whose name the Common Stock certificate is registered shall be deemed to be a shareholder of record on the Conversion Date; provided,
however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons
entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the
person or persons entitled to receive such shares of Common Stock as the 

24

 

record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided,
further, that such conversion shall be at the Conversion Price in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon
conversion of a Security, such person shall no longer be a Holder of such Security. No payment or adjustment will be made for dividends or distributions on shares of Common Stock issued upon
conversion of a Security. 

    Securities
so surrendered for conversion (in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next
succeeding interest payment date (excluding Securities or portions thereof called for redemption on or after August 20, 2004, or presented for purchase upon a Change in Control on a Change in
Control Purchase Date, during the period beginning at the close of business on a regular record date and ending at the opening of business on the first Business Day after the next succeeding interest
payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the
interest payable on such interest payment date on the principal amount of such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the
conversion of such Security, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. Except as otherwise provided in this Section 4.2, no
payment or adjustment will be made for accrued interest on a converted Security. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly
repay such funds to such Holder. 

    Nothing
in this Section shall affect the right of a Holder in whose name any Security is registered at the close of business on a record date to receive the interest payable on such
Security on the related
interest payment date in accordance with the terms of this Indenture and the Securities. If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable
upon the conversion shall be based on the aggregate principal amount of Securities converted. 

    Upon
surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security equal in principal
amount to the unconverted portion of the Security surrendered. 

Section 4.3.  Fractional Shares  

    The
Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company will pay an amount in cash based upon the current market price
(determined as set forth in Section 4.6(g)) of the Common Stock on the Trading Day immediately prior to the Conversion Date. 

Section 4.4.  Taxes on Conversion  

    If
a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion.
However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the
certificate representing the Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares
are to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required by law or regulation. 

Section 4.5.  Company to Provide Stock  

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

25

 

    All shares of Common Stock delivered upon conversion of the Securities or upon the Company's delivery of Common Stock to Holders upon a Provisional Redemption pursuant to
Section 3.7(b) (the "Provisional Redemption Shares") 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. 

    The
Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities or of
Provisional Redemption Shares, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on the NNM or other
over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that if
rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the
provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system or
exchange at such time. 

Section 4.6.  Adjustment of Conversion Price  

    The
conversion price as stated in paragraph 8 of the Securities (the "Conversion Price") shall be adjusted from time to time by
the Company as follows: 

    (a) In
case the Company shall (i) pay a dividend on its Common Stock in shares of Common Stock, (ii) make a distribution on its Common Stock in shares of
Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of shares, or (iv) combine its outstanding Common Stock into a smaller number of shares, the Conversion
Price in effect immediately prior thereto shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock
which it would have owned had such Security been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective
immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combination. 

    (b) In
case the Company shall issue rights or warrants to all or substantially all holders of its Common Stock entitling them (for a period commencing no earlier than
the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a
price per share (or having a conversion price per share) less than the current market price per share of Common Stock (as determined in accordance with subsection (g) of this
Section 4.6) on the record date for the determination of shareholders entitled to receive such rights or warrants, the Conversion Price in effect immediately prior thereto shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such record date by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered
(or the aggregate conversion price of the convertible securities so offered, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible
securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at the current market price per share (as determined in accordance
with subsection (g) of this Section 4.6) of Common Stock on such record date, and of which the denominator shall be the number of shares of Common Stock outstanding on such record date
plus the number of additional shares of Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights
or warrants are issued, and shall become effective immediately after such record date. If at the 

26

 

end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Price shall be immediately readjusted to what it
would have been based upon the number of additional shares of Common Stock actually issued (or the number of shares of Common Stock issuable upon conversion of convertible securities actually issued). 

    (c) In
case the Company shall distribute to all or substantially all holders of its Common Stock any shares of capital stock of the Company (other than Common Stock),
evidences of indebtedness or other non-cash assets (including securities of any person other than the Company but excluding (1) dividends or distributions paid exclusively in cash
or (2) dividends or distributions referred to in subsection (a) of this Section 4.6), or shall distribute to all or substantially all holders of its Common Stock rights or
warrants to subscribe for or purchase any of its securities (excluding those rights and warrants referred to in subsection (b) of this Section 4.6 and also excluding the distribution of
rights to all holders of Common Stock pursuant to the adoption of a shareholders rights plan or the detachment of such rights under the terms of such shareholder rights plan), then in each such case
the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the current Conversion Price by a fraction of which the numerator shall be the current market
price per share (as determined in accordance with subsection (g) of this Section 4.6) of the Common Stock on the record date mentioned below less the fair market value on such record
date (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers' Certificate delivered to the
Trustee) of the portion of the capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock
(determined on the basis of the number of shares of Common Stock outstanding on the record date), and of which the denominator shall be the current market price per share (as defined in subsection
(g) of this Section 4.6) of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately
after the record date for the determination of shareholders entitled to receive such distribution. 

    (d) In
case the Company shall, by dividend or otherwise, at any time distribute (a "Triggering Distribution") to all or
substantially all holders of its Common Stock cash in an aggregate amount that, together with the aggregate amount of (A) any cash and the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of
any tender offer by the Company or a Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of payment of the Triggering Distribution and in
respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made and (B) all other cash distributions to all or substantially all holders of its Common Stock
made within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made,
exceeds an amount equal to 10.0% of the product of the current market price per share of Common Stock (as determined in accordance with subsection (g) of this Section 4.6) on the
Business Day (the "Determination Date") immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the
number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), the Conversion Price shall be reduced so that the same shall equal the
price determined by multiplying such Conversion Price in effect immediately prior to the Determination Date by a fraction of which the numerator shall be the current market price per share of the
Common Stock (as determined in accordance with subsection (g) of this Section 4.6) on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market
value (determined as aforesaid in this Section 4.6(d)(1)) of any such other consideration so distributed, paid or payable within such 12 months (including, without limitation, the
Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date) and the denominator shall be
such current 

27

 

market price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.6) on the Determination Date, such reduction to become effective immediately
prior to the opening of business on the day following the date on which the Triggering Distribution is paid. 

    (e) In
case any tender offer made by the Company or any of its Subsidiaries for Common Stock shall expire and such tender offer (as amended upon the expiration thereof)
shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined by the Board
of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee thereof) of any other consideration) that,
together with the aggregate amount of (A) any cash and the fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall
be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of any other tender offers by the Company or any Subsidiary of the Company for Common
Stock consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Conversion Price adjustment pursuant to this Section 4.6
has been made and (B) all cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the Expiration Date and in respect of which no
Conversion Price adjustment pursuant to this Section 4.6 has been made, exceeds an amount equal to 10.0% of the product of the current market price per share of Common Stock (as determined in
accordance with subsection (g) of this Section 4.6) as of the last date (the "Expiration Date") tenders could have been made pursuant to
such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the "Expiration Time") multiplied by the
number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time, then, immediately prior to the opening of
business on the day after the Expiration 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 close of business on the Expiration Date by a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any
shares held in the treasury of
the Company) at the Expiration Time multiplied by the current market price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.6) on the
Trading Day next succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) payable to shareholders based on the acceptance
(up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and
excluding any shares held in the treasury of the Company) at the Expiration Time and the current market price per share of Common Stock (as determined in accordance with subsection (g) of this
Section 4.6) on the Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. In
the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any
or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have been in effect based upon the number of shares actually purchased. If the
application of this Section 4.6(e) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 4.6(e). 

    (f)  For
purposes of this Section 4.6, the term "tender offer" shall mean and include both tender offers and
exchange offers, all references to "purchases" of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of 

28

 

shares pursuant to exchange offers, and all references to "tendered shares" (and all similar references) shall mean and include shares tendered in both
tender offers and exchange offers. 

    (g) For
the purpose of any computation under subsections (b), (c) (d) and (e) of this Section 4.6, the current market price per share of Common
Stock on any date shall be deemed to be the average of the daily closing prices for the 30 consecutive Trading Days commencing 45 Trading Days before (i) the Determination Date or the
Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (e) of this Section 4.6 or (ii) the record date with respect to distributions,
issuances or other events requiring such computation under subsection (b) (c) or (d) of this Section 4.6. The closing price for each day shall be the last reported sales price or,
in case no such reported sale takes place on such date, the average of the reported closing bid and asked prices in either case on the NNM or, if the Common Stock is not listed or admitted to trading
on the NNM, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on the NNM or any national securities
exchange, the last reported sales price of the Common Stock as quoted on NASDAQ or, in case no reported sales takes place, the average of the closing bid and asked prices as quoted on NASDAQ or any
comparable system or, if the Common Stock is not quoted on NASDAQ or any comparable system, the closing sales price or, in case no reported sale takes place, the average of the closing bid and asked
prices, as furnished by any two members of the National Association of Securities Dealers, Inc. selected from time to time by the Company for that purpose. If no such prices are available, the
current market price per share shall be the fair value of a share of Common Stock as determined by the Board of Directors (which shall be evidenced by an Officers' Certificate delivered to the
Trustee). 

    (h) In
any case in which this Section 4.6 shall require that an adjustment be made following a record date or a Determination Date or Expiration Date, as the
case may be, established for purposes of this Section 4.6, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the
Officers' Certificate) issuing to the Holder of any Security converted after such record date or Determination Date or Expiration Date the shares of Common Stock and other capital stock of the Company
issuable upon such conversion over and above the shares of Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to
adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the
Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or Determination Date or
Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record
date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred. 

Section 4.7.  No Adjustment  

    No
adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price as last adjusted;  provided, however, that any
adjustments which by reason of this Section 4.7 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. 

    Except
as stated above, no adjustment need be made for issuances of Common Stock or any securities convertible into or exchangeable for Common Stock or the right to purchase Common
Stock or such convertible or exchangeable securities. 

    To
the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. 

29

 

Section 4.8.  Adjustment for Tax Purposes  

    The
Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.6, as it in its discretion shall determine to be
advisable in order that any stock
dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the Company to
its shareholders shall not be taxable. 

Section 4.9.  Notice of Adjustment  

    Whenever
the Conversion Price or conversion privilege is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment and file with the Trustee an Officers'
Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers' Certificate setting forth an adjustment of the
Conversion Price, the Trustee may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect. 

Section 4.10.  Notice of Certain Transactions  

    In
the event that: 

    (a) the
Company takes any action which would require an adjustment in the Conversion Price; 

    (b) the
Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and shareholders of the Company
must approve the transaction; or 

    (c) there
is a dissolution or liquidation of the Company, 

the
Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice at least ten days before such
date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (a), (b) or (c) of this Section 4.10. 

Section 4.11.  Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege  

    If
any of the following shall occur, namely: 

    (a) any
reclassification or change of shares of Common Stock issuable upon conversion of the Securities (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, or any other change for which an adjustment is provided in Section 4.6); 

    (b) any
consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not
result in any reclassification of, or change (other than 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) in,
outstanding shares of Common Stock; or 

    (c) any
sale or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any person, 

then
the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, combination, consolidation, merger,
sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind
and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by a holder of
the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to 

30

 

such reclassification, change, combination, consolidation, merger, sale or conveyance. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly
equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 4. If, in the case of any such consolidation, merger, combination, sale or conveyance,
the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a person other than the
successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such
other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the
foregoing. The provisions of this Section 4.11 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances. 

    In
the event the Company shall execute a supplemental indenture pursuant to this Section 4.11, the Company shall promptly file with the Trustee (x) an Officers'
Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other securities or property (including cash) receivable by Holders of the Securities upon the conversion of
their Securities after any such reclassification, change, combination, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have
been complied with and (y) an
Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. 

Section 4.12.  Trustee's Disclaimer  

    The
Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as
conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers' Certificate including the Officers' Certificate with respect thereto
which the Company is obligated to file with the Trustee pursuant to Section 4.9. The Trustee makes no representation as to the validity or value of any securities or assets issued upon
conversion of Securities, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article 4. 

    The
Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.11, but
may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with
the Trustee pursuant to Section 4.11. 

Section 4.13.  Voluntary Reduction  

    The
Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during
the period if the Board of Directors determines that such reduction would be in the best interest of the Company and the Company provides 15 days prior notice of any reduction in the Conversion
Price. 

 
 

ARTICLE 5
  
    SUBORDINATION    
  

Section 5.1.  Agreement of Subordination  

    The
Company covenants and agrees, and each Holder of Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject
to the provisions of this
Article 5; and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. 

31

  

    The
payment of the principal of, premium, if any, and interest on, all Securities (including, but not limited to, the redemption price with respect to the Securities called for
redemption or the Change in Control Purchase Price with respect to the Securities subject to purchase in accordance with Article 3 as provided in this Indenture) issued hereunder shall, to the
extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full in cash, or payment satisfactory to the holders of Senior Indebtedness, of
all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred. 

    No
provision of this Article 5 shall prevent the occurrence of any default or Event of Default hereunder. 

Section 5.2.  Payments to Holders  

    No
payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities (including, but not limited to, the redemption price with respect to the
Securities to be called for redemption or the Change in Control Purchase Price with respect to the Securities subject to purchase in accordance with Article 3 as provided in this Indenture),
except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 5.5, if: 

    (a) a
default in the payment of principal, premium, interest, rent or other obligations due on any Designated Senior Indebtedness occurs and is continuing (or, in the
case of Designated Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease
evidencing such Designated Senior Indebtedness), unless and until such default shall have been cured or waived or shall have ceased to exist and notice thereof has been given to the Trustee; or 

    (b) a
default, other than a payment default, on a Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated Senior
Indebtedness to accelerate its maturity and the Trustee receives a notice of the default (a "Payment Blockage Notice") from a Representative or holder
of Designated Senior Indebtedness. 

    Subject
to the provisions of Section 5.5, if the Trustee receives any Payment Blockage Notice pursuant to clause (b) above, no subsequent Payment Blockage Notice shall
be effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No nonpayment
default that existed or was continuing on
the date of delivery of any Payment Blockage Notice to the Trustee (unless such default was waived, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the
basis for a subsequent Payment Blockage Notice. 

    The
Company may and shall resume payments on and distributions in respect of the Securities upon: 

    (1) in
the case of a payment default, the date upon which the default is cured or waived or otherwise ceases to exist and notice thereof has been given to the Trustee,
or 

    (2) in
the case of a default referred to in clause (b) above, the earlier of (i) 179 days after receipt of a Payment Blockage Notice, and
(ii) the date upon which the default is cured or waived or otherwise ceases to exist, unless this Article 5 otherwise prohibits the payment or distribution at the time of such payment or
distribution. 

    Upon
any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or
winding-up or liquidation or reorganization of the Company (whether voluntary or involuntary) or in bankruptcy, insolvency, receivership or similar proceedings, all amounts due or to
become due upon all Senior Indebtedness shall first be paid in full in cash, or other payment satisfactory to the holders of Senior Indebtedness (except payments made pursuant to Article 10
from monies deposited with the Trustee 

32

 

pursuant thereto prior to commencement of proceedings for such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or
liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other similar proceeding, any payment by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article 5, shall (except as
aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities or by
the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held
by such holders, or as otherwise required by law or a court order) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full in cash, or other payment satisfactory
to the holders of Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the
Holders of the Securities or to the Trustee. 

    In
the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of
the principal of, premium, if any, or interest on the Securities (including, but not limited to, the redemption price with respect to the Securities called for redemption or the Change in Control
Purchase Price with respect to the Securities subject to purchase in accordance with Article 3 as provided in this Indenture), except payments and distributions made by the Trustee as permitted
by the first or second paragraph of Section 5.5, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such
acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of
Senior Indebtedness of such acceleration. 

    In
the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities
(including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Indebtedness is paid in
full, in cash or other payment satisfactory to the holders of Senior Indebtedness, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to
the holders of Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full, in cash
or other payment satisfactory to the holders of Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness. 

    Nothing
in this Section 5.2 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 9.7. This Section 5.2 shall be subject to the
further provisions of Section 5.5. 

    For
purposes of this Article 5, the words, "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or
securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this
Article 5 with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not 

33

 

assumed by the Company or the new corporation, as the case may be) are not, without the consent of such Holders, altered by such reorganization or readjustment. The consolidation of the Company with,
or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided for in Article 7 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 5.2 if
such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article 7. 

Section 5.3.  Subrogation of Securities  

    Subject
to the payment in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, of all Senior Indebtedness, the rights of the Holders of the Securities
shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 5 (equally and ratably with the
holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Securities are subordinated and is
entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior
Indebtedness until the principal, premium, if any, and interest on the Securities shall be paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness. For the purposes of
such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled
except for the provisions of this Article 5, and no payment pursuant to the provisions of this Article 5, to or for the benefit of the holders of Senior Indebtedness by Holders of the
Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness. No payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities, pursuant to the subrogation provisions of this
Article 5, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood
that the provisions of this Article 5 are and are intended solely for the purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness, on the other hand. 

    Nothing
contained in this Article 5 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the
holders of Senior Indebtedness, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of, and
premium, if any, and interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders
of the Securities and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Security from exercising
all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 5 of the holders of Senior Indebtedness in respect of
cash, property or securities of the Company received upon the exercise of any such remedy. 

    Upon
any payment or distribution of assets of the Company referred to in this Article 5, the Trustee, subject to the provisions of Section 9.1, and the Holders of the
Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization
proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution,
delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and 

34

 

other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 5. 

Section 5.4.  Authorization to Effect Subordination  

    Each
Holder of a Security by the Holder's acceptance thereof authorizes and directs the Trustee on the Holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article 5 and appoints the Trustee to act as the Holder's attorney-in-fact for any and all such purposes. If the Trustee
does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 5.3 hereof at least 30 days before the expiration of the time
to file such claim, the holders of any Senior Indebtedness or their representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities. 

Section 5.5.  Notice to Trustee  

    The
Company shall give prompt written notice in the form of an Officers' Certificate to a Trust Officer of the Trustee and to any Paying Agent of any fact known to the Company which
would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 5. Notwithstanding the
provisions of this Article 5 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any
payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 5, unless and until a Trust Officer of the Trustee shall have received written
notice thereof at the Corporate Trust Office from the Company (in the form of an Officers' Certificate) or a Representative or a holder or holders of Senior Indebtedness or from any trustee thereof;
and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 9.1, shall be entitled in all respects to assume that no such facts exist; provided that if
on a date not fewer than one Business Day prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 5.5, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall
not be affected by any notice to the contrary which may be received by it on or after such prior date. Notwithstanding anything in this Article 5 to the contrary, nothing shall prevent any
payment by the Trustee to the Holders of monies deposited with it pursuant to Article 10, and any such payment shall not be subject to the provisions of Article 5. 

    The
Trustee, subject to the provisions of Section 9.1, shall be entitled to rely on the delivery to it of a written notice by a Representative or a person representing himself
to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf
of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Article 5, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under
this Article 5, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

35

 

Section 5.6.  Trustee's Relation to Senior Indebtedness  

    The
Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 5 in respect of any Senior Indebtedness at any time held by it, to the same
extent as any other holder of Senior Indebtedness, and nothing in Section 9.11 or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. 

    With
respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this
Article 5, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 9.1, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay
over or deliver to Holders of Securities, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article 5 or otherwise. 

Section 5.7.  No Impairment of Subordination  

    No
right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 

Section 5.8.  Certain Conversions Deemed Payment  

    For
the purposes of this Article 5 only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 4 shall not
be deemed to constitute a payment or distribution on account of the principal of (or premium, if any) or interest on Securities or on account of the purchase or other acquisition of Securities, and
(2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 4.3), property or securities (other than junior securities) upon conversion
of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 5.8, the term "junior
securities" means (a) shares of any stock of any class of the Company, or (b) securities of the Company which are subordinated in right of payment to all Senior
Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as
provided in this Article. Nothing contained in this Article 5 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 4. 

Section 5.9.  Article Applicable to Paying Agents  

    If
at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article shall (unless
the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article
in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 5.5 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent. 

Section 5.10.  Senior Indebtedness Entitled to Rely  

    The
holders of Senior Indebtedness (including, without limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article 5, and no amendment or
modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. 

36

 
 
 

ARTICLE 6
  
    COVENANTS

    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

exclusively on Officers' Certificates).

    (1) the
Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties

ARTICLE 8
  
    DEFAULT AND REMEDIES    
  

Section 8.1.  Events of Default  

    An
"Event of Default" shall occur if: 

    (1) the
Company defaults in the payment of any principal of (including, without limitation, any premium, if any, on) any Security when the same becomes due and payable
(whether at maturity, upon redemption, on a Change of Control Purchase Date or otherwise), whether or not such payment shall be prohibited by the provisions of Article 5 hereof; 

    (2) the
Company defaults in the payment of any interest on any Security when the same becomes due and payable if such failure continues for 30 days, whether or
not such payment shall be prohibited by the provisions of Article 5 hereof; 

    (3) the
Company fails to comply with any of its other agreements contained in the Securities or this Indenture and the default continues for 60 days after the
notice specified below is given; 

    (4) the
Company defaults in the payment of the purchase price of any Security when the same becomes due and payable, whether or not such payment shall be prohibited by
the provisions of Article 5 hereof; 

    (5) the
Company fails to provide timely notice of a Change in Control; 

    (6) the
Company pursuant to or within the meaning of any Bankruptcy Law: 

    (i)  commences
a voluntary case or proceeding; 

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

39

 

    (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property; or 

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

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

    (i)  is
for relief against the Company in an involuntary case or proceeding; 

    (ii) appoints
a Custodian of the Company or for all or substantially all of the property of the Company; or 

    (iii) orders
the liquidation of the Company; 

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

    The
term "Bankruptcy Law" means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for
the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy
Law. 

    A
default under clause (3) 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 then outstanding notify the Company and the Trustee, of the default, and the Company does not cure the default within 60 days after receipt of such notice. The notice given pursuant
to this Section 8.1 must specify the default, demand that it be remedied and state that the notice is a "Notice of Default." When any default under this Section 8.1 is cured, it ceases. 

    The
Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer at the Corporate Trust Office of the
Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder. 

Section 8.2.  Acceleration  

    If
an Event of Default (other than an Event of Default specified in clause (6) or (7) of Section 8.1) occurs and is continuing, the Trustee may, by notice to the
Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal on the Securities
then outstanding (if not then due and payable) to
be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (6) or (7) of Section 8.1
occurs, all unpaid principal of the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any
Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing
Events of Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the
payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of interest and overdue principal, which has become due otherwise than
by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to
the Trustee and any predecessor Trustee under Section 9.7 have been made. 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 by proceeding at law or in equity to collect the payment
of the principal 

40

 

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

Section 8.4.  Waiver of Defaults and Events of Default  

    Subject
to Sections 8.7 and 11.2, the Holders of a majority in principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of
Default and its consequence, except a default or Event of Default in the payment of the principal of or interest on any Security, a failure by the Company to convert any Securities into Common Stock
or any default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 11.2, cannot be modified or amended without the consent of the Holder of
each Security affected. When a default or Event of Default is waived, it is cured and ceases. 

Section 8.5.  Control by Majority  

    The
Holders of a majority in principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it;  provided, however, that the
Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

Section 8.6.  Limitations on Suits  

    A
Holder may not pursue any remedy with respect to this Indenture or the Securities (except actions for payment of overdue principal or interest or for the conversion of the
Securities pursuant to Article 4) unless: 

    (1) the
Holder gives to the Trustee written notice of a continuing Event of Default; 

    (2) the

payment of such interest is lawful, interest on overdue principal and on overdue installments of interest, in each case at the rate per annum borne by the Securities and such further amount as shall

on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the
same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.7, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for
any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to
receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to, or, on behalf of
any Holder, to authorize, accept or adopt 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 9.1.  Duties of Trustee  

    (a)
If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and

upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any provision
hereof are specifically required to be delivered to the Trustee to determine whether or not they conform on their face to the requirements of this Indenture. 

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

    (1) this
paragraph does not limit the effect of subsection (b) of this Section 9.1; 

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

Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to
Section 8.5. 

    (d)
No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers unless the Trustee shall have received adequate indemnity in its opinion against potential costs and liabilities incurred by it relating
thereto.

    (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 or direction of any of the Holders pursuant to this
Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction. 

    (g)
The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request,
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.

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. 

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 an Affiliate of the Company with the same
rights it 

44

 

would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to 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 of the proceeds from the
Securities, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. 

Section 9.5.  Notice of Default or Events of Default  

    If
a default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Securityholder notice of the default or Event of Default
within 90 days after it occurs. However, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the
interests of Securityholders, except in the case of a default or an Event of Default in payment of the principal of or interest on any Security. 

Section 9.6.  Reports by Trustee to Holders  

    If
such report is required by TIA Section 313, within 60 days after each December 15, beginning with the December 15 following the date of this Indenture,
the Trustee shall mail to each Securityholder a brief report dated as of such December 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b)(2) and (c). 

    A
copy of each report at the time of its mailing to Securityholders shall be mailed to the Company and filed with the SEC and each stock exchange or market quotation system, if any,
on which the Securities are listed. The Company shall notify the Trustee whenever the Securities become listed on any stock exchange or listed or admitted to trading on any quotation system and any
changes in the stock exchanges or quotation systems on which the Securities are listed or admitted to trading and of any delisting thereof. 

Section 9.7.  Compensation and Indemnity  

    The
Company shall pay to the Trustee from time to time such compensation (as agreed to from time to time by the Company and the Trustee in writing) for its services (which
compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon request for all reasonable,
actual disbursements, out-of-pocket expenses and advances incurred or made by it. Such expenses may include the reasonable, actual compensation, disbursements and expenses of
the Trustee's agents and counsel. 

    The
Company shall indemnify the Trustee or any predecessor Trustee (which for purposes of this Section 9.7 shall include its officers, directors, employees and Agents) for, and
hold it harmless against, any and all loss, liability or expense including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), including reasonable legal fees
(whether incurred before any trial, at trial, on appeal or in any bankruptcy or arbitration proceedings) and expenses incurred by it in connection with the acceptance or administration of its duties
under this Indenture or any action or failure to act as authorized or within the discretion or rights or powers conferred upon the Trustee hereunder including the reasonable costs and expenses of the
Trustee and its counsel in defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim asserted against the Trustee for which it may seek indemnity. The Company need not pay for any settlement without its written consent, which shall not be unreasonably withheld. 

    The
Company need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it resulting from its gross negligence or bad faith. 

45

 

    To secure the Company's payment obligations in this Section 9.7, the Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or
property held or collected by the Trustee, except such money or property held in trust to pay the principal of and interest on the Securities. The obligations of the Company under this
Section 9.7 shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. 

    When
the Trustee incurs expenses or renders services after an Event of Default specified in clause (3) or (4) of Section 8.1 occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section shall survive the termination of this Indenture. 

Section 9.8.  Replacement of Trustee  

    The
Trustee may resign by so notifying the Company. The Holders of a majority in principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee
and may, with the Company's written consent, appoint a successor Trustee. The Company may remove the Trustee if: 

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

    (2) the
Trustee is adjudged a bankrupt or an insolvent; 

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

    (4) the
Trustee 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 a successor Trustee. The resignation or removal
of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as described below. 

    If
a successor Trustee does not take office within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of 10% in
principal amount of the Securities then outstanding may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company. 

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

    A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all
property held by it as Trustee to the successor Trustee and be released from its obligations (exclusive of any liabilities that the retiring Trustee may have incurred while acting as Trustee)
hereunder, 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. A
successor Trustee shall promptly mail notice of its succession to each Holder. 

    A
retiring Trustee shall not be liable for the acts or omissions of any successor Trustee after its succession. 

    Notwithstanding
replacement of the Trustee pursuant to this Section 9.8, the Company's obligations under Section 9.7 shall continue for the benefit of the retiring
Trustee. 

Section 9.9.  Successor Trustee by Merger, etc.  

    If
the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust assets (including the administration of this Indenture) to,
another corporation, the resulting, surviving or transferee corporation, without any further act, shall be the successor Trustee, 

46

 

provided such transferee corporation shall qualify and be eligible under Section 9.10. Such successor Trustee shall promptly mail notice of its succession to the Company and each Holder. 

Section 9.10.  Eligibility; Disqualification  

    The
Trustee shall always satisfy the requirements of paragraphs (1), (2) and (5) of TIA Section 310(a). The Trustee (or its parent holding company) shall have a
combined capital and surplus of at least $50,000,000. If at any time the Trustee shall cease to satisfy any such requirements, it shall resign immediately in the manner and with the effect specified
in this Article 9. The Trustee shall be subject to the provisions of TIA Section 310(b). Nothing herein shall prevent the Trustee from filing with the SEC 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. 

 
 

ARTICLE 10
  
    SATISFACTION AND DISCHARGE OF INDENTURE    
  

Section 10.1.  Satisfaction and Discharge of Indenture  

    This
Indenture shall cease to be of further effect (except as to any surviving rights of conversion, registration of transfer or exchange of Securities herein expressly provided for
and except as further provided below), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture,
when 

    (a)
either 

    (1) all
Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 2.7 and (ii) Securities for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company as provided in
Section 10.3) have been delivered to the Trustee for cancellation; or 

    (2) all
such Securities not theretofore delivered to the Trustee for cancellation 

    (i)  have
become due and payable, or 

    (ii) will
become due and payable at the Final Maturity Date within 90 days, or 

    (iii) are
to be called for redemption within 90 days under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the
name, and at the expense, of the Company, 

and
the Company, in the case of clause (i), (ii) or (iii) above, has irrevocably deposited or caused to be irrevocably deposited with the Trustee or a Paying Agent (other than the
Company or any of its Affiliates) as trust funds in trust for the purpose cash in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the
Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Final Maturity Date or Redemption Date, as the
case may be; 

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

47

 

    (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of this Indenture have been complied with. 

    Notwithstanding
the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 9.7 shall survive and, if money shall have been
deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section, the provisions of Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.12, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13 and 12.5,
Article 4, the last paragraph of Section 6.2 and this Article 10, shall survive until the Securities have been paid in full. 

Section 10.2.  Application of Trust Money  

    Subject
to the provisions of Section 10.3, the Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money deposited with it pursuant to
Section 10.1 and shall apply the deposited money in accordance with this Indenture and the Securities to the payment of the principal of and interest on the Securities. Money so held in trust
shall not be subject to the subordination provisions of Article 5. 

Section 10.3.  Repayment to Company  

    The
Trustee and each Paying Agent shall promptly pay to the Company upon request any excess money (i) deposited with them pursuant to Section 10.1 and (ii) held
by them at any time. 

    The
Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a
right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the
expense of the Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days
from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for
payment as general creditors. 

Section 10.4.  Reinstatement  

    If
the Trustee or any Paying Agent is unable to apply any money in accordance with Section 10.2 by reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities shall be revived and reinstated
as though no deposit had occurred pursuant to Section 10.1 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 10.2;  provided, however, that if the Company has made any payment of the principal of or interest on any Securities because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee or such Paying Agent. 

 
 

ARTICLE 11
  
    AMENDMENTS, SUPPLEMENTS AND WAIVERS    
  

Section 11.1.  Without Consent of Holders  

    The
Company and the Trustee may amend or supplement this Indenture or the Securities without notice to or consent of any Securityholder: 

    (a)
to comply with Sections 4.11 and 7.1; 

    (b)
to cure any ambiguity, defect or inconsistency; 

48

 

    (c) to make any other change that does not adversely effect the rights of any Securityholder; 

    (d)
to comply with the provisions of the TIA; or 

    (e)
to appoint a successor Trustee. 

Section 11.2.  With Consent of Holders  

    The
Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in aggregate principal amount of
the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Securities without notice to any Securityholder. However, notwithstanding the foregoing but subject to Section 11.4, without the written consent of each
Securityholder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 8.4, may not: 

    (a)
change the stated maturity of the principal of, or interest on, any Security; 

    (b)
reduce the principal amount of, or any premium or interest on, any Security; 

    (c)
reduce the amount of principal payable upon acceleration of the maturity of any Security; 

    (d)
change the place or currency of payment of principal of, or any premium or interest on, any Security; 

    (e)
impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security; 

    (f)
modify the subordination provisions of Article 5 in a manner materially adverse to the Holders of Securities; 

    (g)
adversely affect the right of Holders to convert Securities other than as provided in or under Section 4 of this Indenture; 

    (h)
reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification or amendment; 

    (i)
reduce the percentage of the aggregate principal amount of the outstanding Securities necessary for the waiver of compliance with certain provisions of this Indenture or the
waiver of certain defaults under this Indenture; and 

    (j)
modify any of the provisions of this Section or Section 8.4, except to increase any such percentage or to provide that certain provisions of this Indenture cannot be
modified or waived without the consent of the Holder of each outstanding Security affected thereby. 

    It
shall not be necessary for the consent of the Holders under this Section 11.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be
sufficient if such consent approves the substance thereof. 

    After
an amendment, supplement or waiver under this Section 11.2 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement
or waiver. An amendment or supplement under this Section 11.2 or under Section 11.1 may not make any change that adversely affects the rights under Article 5 of any holder of an
issue of Senior Indebtedness unless the holders of that issue, pursuant to its terms, consent to the change. 

Section 11.3.  Compliance with Trust Indenture Act  

    Every
amendment to or supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement. 

49

  

Section 11.4.  Revocation and Effect of Consents  

    Until
an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a
Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 

    After
an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (a) through (j) of
Section 11.2. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security
that evidences the same debt as the consenting Holder's Security. 

Section 11.5.  Notation on or Exchange of Securities  

    If
an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall
issue and the Trustee shall authenticate a new Security that reflects the changed terms. 

Section 11.6.  Trustee to Sign Amendments, Etc.  

    The
Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 11 if the amendment or supplemental indenture does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental
indenture, the Trustee shall be entitled to receive and, subject to Section 9.1, shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or supplemental
indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it.

    FEI COMPANY
  5.5% CONVERTIBLE SUBORDINATED NOTES DUE AUGUST 15, 2008    
  

1.
INTEREST 

    FEI
Company, an Oregon corporation (the "Company", which term shall include any successor corporation under the Indenture hereinafter
referred to), promises to pay interest on the principal amount of this Security at the rate of 5.5% per annum. The Company shall pay interest semiannually on February 15 and August 15 of
each year, commencing February 15, 2002. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from
August 3, 2001; provided, however, that if there is not an existing default in the payment of interest and if this Security is authenticated
between a record date referred to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest payment date. 

    Additional
interest shall accrue daily on the Securities from and including the date on which any Registration Default, as defined in the Registration Rights Agreement, shall occur
to, but excluding, the date on which all such registration Defaults have been cured, at a rate of 0.50% per annum for the Securities, and, if applicable, on an equivalent basis per share (subject to
adjustment in the case of stock splits, stock recombinations, stock dividends and the like) of Common Stock issuable upon conversion of the Securities (the "Additional
Interest"). 

2.
METHOD OF PAYMENT 

    The
Company shall pay interest on this Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on February 15 or
August 15, as the case may be, next preceding the related interest payment date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay
principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may, however, pay principal and interest in
respect of any Certificated Security by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in
excess of $2,000,000 may, at such Holder's option, be paid by wire transfer in immediately available funds. The Company may mail an interest check to the Holder's registered address. Notwithstanding
the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of
the Depositary or its nominee. 

3.
PAYING AGENT, REGISTRAR AND CONVERSION AGENT 

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

4.
INDENTURE, LIMITATIONS 

    This
Security is one of a duly authorized issue of Securities of the Company designated as its 5.5% Convertible Subordinated Notes Due August 15, 2008 (the
"Securities"), issued under an Indenture dated as of August 3, 2001 (together with any supplemental indentures thereto, the
"Indenture"), between the Company and the Trustee. The terms of this Security include those stated in the Indenture and those required by or made part
of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this Security is
referred to the Indenture and said Act for a statement of them. 

A–4

 

    The Securities are subordinated unsecured obligations of the Company limited to $175,000,000 aggregate principal amount, subject to Sections 2.2 and 2.7 of the Indenture. The
Indenture does not limit other debt of the Company, secured or unsecured, including Senior Indebtedness. 

5.
PROVISIONAL AND OPTIONAL REDEMPTION 

    (a)
The Securities are subject to redemption, as a whole or from time to time in part, at any time on or after August 20, 2004, on at least 20 and no more than 60 days'
notice, at the election of the Company. The Redemption Prices (expressed as percentages of the principal amount) are as follows for the Securities redeemed during the periods set forth below: 

	Period
 
	 	Percentage

	Beginning August 20, 2004 through August 14, 2005	 	102.750%
	

Beginning August 15, 2005 through August 14, 2006	
 	

101.833%
	

Beginning August 15, 2006 through August 14, 2007	
 	

100.917%
	

Beginning August 15, 2007 and thereafter	
 	

100.00%  

in
each case together with accrued interest up to but excluding the date of redemption (the "Optional Redemption Date"), and Additional Interest
thereon, if any; provided that if the Optional Redemption Date is an interest payment date, interest will be payable to the Holders in whose name the Securities are registered at the close of business
on the relevant record dates for payment of such interest. 

    (b)
The Securities are subject to redemption, as a whole or from time to time in part, at any time on or prior to August 20, 2004 (a "Provisional
Redemption"), upon at least 20 and not more than 60 days' notice, at the election of the Company, by mail to the Holders of the Securities, at a redemption price equal
to $1,000 per $1,000 principal amount of the Securities redeemed plus accrued and unpaid interest, if any, and Additional Interest thereon, if any, to but excluding the date of redemption (the
"Provisional Redemption Date"), if (1) the Closing Sale Price of the Common Stock has exceeded 150% of the Conversion Price for at least 20
Trading Days within a period of any 30 consecutive Trading Days ending on the Trading Day prior to the date of the mailing of the notice of Provisional Redemption, and (2) a shelf registration
statement covering resales of the Securities and the Common Stock issuable upon conversion thereof is effective and available for use and is expected to remain effective and available for use for the
30 days following the Provisional Redemption Date unless registration is no longer required; provided that if the Provisional Redemption Date is an interest payment date, interest will be
payable to the Holders in whose name the Securities are registered at the close of business on the relevant record dates for payment of such interest. 

    Upon
any Provisional Redemption, the Company shall make an additional payment, at its option, in cash or Common Stock or a combination of cash and Common Stock with respect to the
Securities called for redemption to Holders on the Notice Date in an amount equal to $166.83 per $1,000 principal amount of the Securities, less the amount of any interest actually paid (including, if
the Provisional Redemption Date occurs after a record date but before an interest payment date, any interest paid or to be paid in connection with such interest payment date) on such Securities on or
prior to the Provisional Redemption Date. The Company shall make such additional payment on all Securities called for Provisional Redemption, including those Securities converted into Common Stock
between the Notice Date and the Provisional Redemption Date. 

6.
NOTICE OF REDEMPTION 

    Notice
of redemption will be mailed by first-class mail at least 20 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed
at its registered address. Securities in denominations larger than $1,000 may be redeemed in part, but only in whole multiples of $1,000. On and after the Redemption Date, subject to the deposit with
the Paying Agent of funds 

A–5

 

sufficient to pay the Redemption Price plus accrued interest, if any, accrued to, but excluding, the Redemption Date, interest shall cease to accrue on Securities or portions of them called for
redemption. 

7.
PURCHASE OF NOTES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL 

    At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long
as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date that is 30 Business Days after the occurrence of a
Change in Control, at a purchase price equal to 100% of the principal amount thereof together with accrued interest up to, but excluding, the Change in Control Purchase Date. The Holder shall have the
right to withdraw any Change in Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business
on the Business Day next preceding the Change in Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 

8.
CONVERSION 

    A
Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of
Common Stock at any time prior to the close of business on the Business Day immediately preceding August 15, 2008; provided, however, that if the
Security is called for redemption or subject to purchase upon a Change in Control, the conversion right will terminate at the close of business on the Business Day immediately preceding the redemption
date or the Change in Control Purchase Date, as the case may be, for such Security or such earlier date as the Holder presents such Security for redemption or purchase (unless the Company shall
default in making the redemption payment or paying the Change in Control Purchase Price, as the case may be, when due, in which case the conversion right shall terminate at the close of business on
the date such default is cured and such Security is redeemed or purchased). 

    The
initial Conversion Price is $49.52 per share, subject to adjustment under certain circumstances. The number of shares of Common Stock issuable upon conversion of a Security is
determined by dividing the principal amount of the Security or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon conversion.
Instead of issuing fractional shares, an amount will be paid in cash based upon the Closing Price Per Share (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to
the Conversion Date. 

    To
convert a Security, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender
the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax,
if required. Securities so surrendered for conversion (in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next succeeding
interest payment date (excluding Securities or portions thereof called for redemption on or after August 20, 2004 or subject to purchase upon a Change in Control on a Redemption Date or Change
in Control Purchase Date, as the case may be, during the period beginning at the close of business on a regular record date and ending at the opening of business on the first Business Day after the
next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of
an amount equal to the interest payable on such interest payment date on the principal amount of such Security then being converted, and such interest shall be payable to such registered Holder
notwithstanding the conversion of such Security, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. If the Company defaults in the payment of
interest payable on such interest payment date, the Company shall 

A–6

 

promptly repay such funds to such Holder. A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. 

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

9.
CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION 

    Any
Securities called for redemption, unless surrendered for conversion before the close of business on the Business Day immediately preceding the Redemption Date, may be deemed to be
purchased from the Holders of such Securities at an amount not less than the Redemption Price, together with accrued interest, if any, to, but not including, the Redemption Date, by one or more
investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such
Securities to the Paying Agent in trust for such Holders. 

10.
SUBORDINATION 

    The
indebtedness evidenced by the Securities is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of
all Senior Indebtedness of the Company. Any Holder by accepting this Security agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect. In addition
to all other rights of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions
irrespective of any amendment, modification or waiver of any terms of any instrument relating to the Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 

11.
DENOMINATIONS, TRANSFER, EXCHANGE 

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

12.
PERSONS DEEMED OWNERS 

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

13.
UNCLAIMED MONEY 

    If
money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After
that, Holders entitled to money must look to the Company for payment. 

14.
AMENDMENT, SUPPLEMENT AND WAIVER 

    Subject
to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the
Securities then outstanding, and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance
with the consent of the Holders of a majority in principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 

A–7

 

15. SUCCESSOR CORPORATION 

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

16.
DEFAULTS AND REMEDIES 

    Under
the Indenture, an Event of Default includes: (i) default in payment of any principal (including, without limitation, any premium, if any) on the Securities when due;
(ii) failure by the Company after notice to it to comply with any of its other agreements contained in the Indenture or the Securities; and (iii) certain events of bankruptcy, insolvency
or reorganization of the Company. If an Event of Default (other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Securities then outstanding may declare all unpaid principal to the date of acceleration on the Securities then outstanding to be due and payable
immediately, all as and to the extent provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid
principal of the Securities then outstanding 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. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it
before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the Securities then outstanding may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in
their interests. The Company is required to file periodic reports with the Trustee as to the absence of default. 

17.
TRUSTEE DEALINGS WITH THE COMPANY 

    BNY
Western Trust Company, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an
Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 

18.
NO RECOURSE AGAINST OTHERS 

    A
director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture nor for any
claim based on, in respect of or by reason of such obligations or their creation. The Holder of this Security by accepting this Security waives and releases all such liability. The waiver and release
are part of the consideration for the issuance of this Security. 

19.
AUTHENTICATION 

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

20.
ABBREVIATIONS AND DEFINITIONS 

    Customary

    REGISTRATION RIGHTS AGREEMENT    
  

August 3,
2001 

Credit
Suisse First Boston Corporation

Eleven Madison Avenue

New York, New York 10010-3629 

Ladies
and Gentlemen: 

    FEI
Company, an Oregon corporation (the "Company"), proposes to issue and sell to Credit Suisse First Boston Corporation (the
"Initial Purchaser"), upon the terms set forth in a purchase agreement of even date herewith (the "Purchase
Agreement"), up to $175,000,000 aggregate principal amount of its 5.5% Convertible Subordinated Notes due 2008 (the "Notes").
The Notes will be convertible into shares of common stock of the Company (the "Common Stock") at the conversion price set forth in
the Offering Circular dated July 31, 2001. The Notes will be issued pursuant to an Indenture, dated as of August 3, 2001 (the
"Indenture"), by and between the Company and BNY Western Trust Company, as trustee (the "Trustee"). As
an inducement to the Initial Purchaser to enter into the Purchase Agreement, the Company agrees with the Initial Purchaser, (i) for the benefit of the Initial Purchaser and (ii) for the
benefit of the holders of the Notes and the Common Stock issuable upon conversion or provisional redemption of the Notes (collectively, the
"Securities") from time to time until such time as such Securities have been sold pursuant to a Shelf Registration Statement (as defined below) (each of
the foregoing a "Holder" and, together, the "Holders"), as follows: 

    1.  Shelf Registration.  The Company shall take the following actions: 

    (a) The
Company shall promptly (but in no event more than 90 days after the first date of original issuance of the Notes (such 90th day being a
"Filing Deadline")) file with the Commission and thereafter use its commercially reasonable efforts to cause to be declared effective no later than
180 days after the first date of original issuance of the Notes (such 180th day being an "Effectiveness Deadline") a registration statement (the
"Shelf Registration Statement") on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as
defined herein) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act
(hereinafter, the "Shelf Registration"); provided, however, that no Holder (other than the Initial
Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement
applicable to such Holder. 

    (b) The
Company shall use its commercially reasonable efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included
therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 2(h) below) from the date of its
effectiveness or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) may be sold
pursuant to Rule 144(k) under the Securities Act (or any successor rule therefore) (in any case, such period being called the "Shelf Registration
Period"). The Company shall be deemed not to have used its commercially reasonable efforts to keep the Shelf Registration Statement effective during the requisite period if it
voluntarily takes any action that would result in Holders of Securities covered thereby not being 

 

able to offer and sell such Securities during that period, unless such action is required by applicable law. 

    (c) Notwithstanding
any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any
amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements
of the Securities Act and the rules and
regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made, not misleading. 

    (d) Each
Holder of Transfer Restricted Securities agrees that if such Holder wishes to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement
and related prospectus, it will do so only in accordance with this Section 1(d) and Section 2(b). Each Holder of Transfer Restricted Securities wishing to sell Transfer Restricted
Securities pursuant to a Shelf Registration Statement and related prospectus agrees to deliver a written notice, substantially in the form of Annex A to the Offering Circular (a
"Notice and Questionnaire") to the Company at least five (5) Business Days (a "Business Day"
meaning each day that is not a legal holiday) prior to any intended distribution of Transfer Restricted Securities under the Shelf Registration Statement (each such Holder delivering the Notice and
Questionnaire, a "Notice Holder"). From and after the date the Shelf Registration Statement is declared effective, the Company shall, as promptly as
practicable after the date of receipt of a Notice and Questionnaire (i) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration
Statement or prepare and, if required by applicable law, file a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any
other document required under the Securities Act so that the Holder delivering such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related
prospectus in such a manner as to permit such Holder to deliver such prospectus to purchasers of the Transfer Restricted Securities in accordance with applicable law and, if the Company shall
file a post-effective amendment to the Shelf Registration Statement, use reasonable efforts to cause such post-effective amendment to be declared effective under the
Securities Act as promptly as is practicable, but in any event by the date (the "Amendment Effectiveness Deadline Date") that is thirty
(30) Business Days after the date such post-effective amendment is required by this clause to be filed; (ii) provide such Holder copies of any documents filed pursuant to
Section 1(d)(i); and (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to
Section 1(d)(i); provided that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall
take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 2(b). Notwithstanding anything contained herein
to the contrary, (i) the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Registration Statement or related prospectus and
(ii) the Amendment Effectiveness Deadline Date shall be extended by up to ten (10) days from the expiration of a Deferral Period (and the Company shall incur no obligation to pay
Additional Interest during such extension) if such Deferral Period is in effect on the Amendment Effectiveness Deadline Date; and provided further, that the Company shall not be obligated to file more
than one (1) post-effective amendment or supplement in any twenty (20) day period following the date the Shelf Registration Statement is declared effective for the purpose of
naming Holders as selling securityholders who were not named in the Shelf Registration Statement at the time of effectiveness. Any Holder who, subsequent to the date the Registration Statement is
declared effective, provides a Notice and Questionnaire required by this Section 1(d) pursuant to the provisions of this Section (whether or 

2

 

not such Holder has supplied the Notice and Questionnaire at the time the Shelf Registration Statement was declared effective) shall be named as a selling securityholder in the Shelf Registration
Statement and related prospectus in accordance with the requirements of this Section 1(d). 

    2.  Registration Procedures.  In connection with any Shelf Registration contemplated by Section 1
hereof, the following provisions shall apply: 

    (a) The
Company shall (i) furnish to the Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Shelf Registration Statement and each
amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that the Initial Purchaser (with respect to any portion of an unsold allotment from the original
offering) is participating in the Shelf Registration Statement, the Company shall use its reasonable efforts to reflect in each such document, when so filed with the Commission, such comments as the
Initial Purchaser reasonably may propose within a reasonable period of time; and (ii) include the names of the Holders who propose to sell Securities pursuant to the Shelf Registration
Statement, as selling shareholders. 

    (b) Upon
(A) the issuance by the SEC of a stop order suspending the effectiveness of a Shelf Registration Statement or the initiation of proceedings with respect
to a Shelf Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a "Material
Event") as a result of which any Registration Statement shall contain any 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 not misleading, or any prospectus shall contain any 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 the light of the circumstances under which they were made, not misleading, or (C) the occurrence or existence of any pending corporate development,
public filing with the SEC or other similar event with respect to the Company that, in the reasonable discretion of the Company, makes it appropriate to suspend the availability of a Shelf
Registration Statement and the related prospectus, (i) in the case of clause (B) above, subject to the next sentence, as promptly as practicable prepare and file, if necessary pursuant
to applicable law, a post-effective amendment to such Registration Statement or a supplement to the related prospectus or any document incorporated therein by reference or file any other
required document that would be incorporated by reference into such Registration Statement and prospectus so that such Registration Statement does not contain any 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 not misleading, and such prospectus does not contain any 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 the light of the circumstances under which they were made, not misleading, and, in
the case of a post-effective amendment to a Registration Statement, subject to the next sentence, use reasonable efforts to cause it to be declared effective as promptly as is practicable,
and (ii) give notice to the Notice Holders that the availability of the Shelf Registration Statement is suspended (a "Deferral Notice") and, upon
receipt of any Deferral Notice, each Notice Holder agrees not to sell any Transfer Restricted Securities pursuant to the Registration Statement until such Notice Holder's receipt of copies of the
supplemented or amended prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the prospectus may be used, and has received copies of any additional
or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus. The Company will use reasonable efforts to ensure that the use of the prospectus may be resumed
(x) in the case of clause (A) above, as promptly as is practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company, public disclosure
of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid 

3

 

unreasonable burden or expense, as soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of the Company, such suspension is no longer
appropriate. The Company shall be entitled to exercise its right under this Section 2(b) to suspend the availability of the Shelf Registration Statement or any prospectus, without incurring or
accruing any obligation to pay Additional Interest pursuant to Section 6, for one or more periods not to exceed 90 consecutive days and not to exceed, in the aggregate, 120 days in any
12-month period (such period, during which the availability of the Registration Statement and any prospectus is suspended being a "Deferral
Period"). 

    (c) The
Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Shelf
Registration Statement. 

    (d) The
Company shall furnish to each Notice Holder included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration
Statement and any post-effective amendment thereto (other than an amendment or supplement solely with respect to including the name of a Notice Holder in the Shelf Registration Statement,
in which case, the Company shall furnish such amendment solely to such Notice Holder), including financial statements and schedules. 

    (e) The
Company shall, during the Shelf Registration Period, deliver to each Notice Holder included within the coverage of the Shelf Registration, without charge, as
many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The
Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each Notice Holder of the Securities in connection with the
offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

    (f)  Prior
to any public offering of the Securities pursuant to the Shelf Registration Statement the Company shall register or qualify or cooperate with the Notice
Holders and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or "blue sky" laws of such states of the United
States as any Notice Holder reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered
by the Shelf Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any
jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 

    (g) The
Company shall cooperate with the Notice Holders to facilitate the timely preparation and delivery of certificates representing the Securities to be sold
pursuant to the Shelf Registration Statement free of any restrictive legends and in such denominations and registered in such names as
the Notice Holders may request in writing a reasonable period of time prior to sales of the Securities pursuant to the Shelf Registration Statement. 

    (h) If
the Company notifies the Initial Purchaser and the Holders in accordance with Section 2(b) above to suspend the use of the prospectus until the requisite
changes to the prospectus have been made, then the Initial Purchaser and the Holders shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided
for in Section 1(b) above shall be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchaser and the Holders
shall have received such amended or supplemented prospectus pursuant to this Section 2(h). 

4

 

    (i)  Not later than the effective date of the Shelf Registration Statement, the Company will provide a CUSIP number for the Notes and the Common Stock registered under
the Shelf Registration Statement, and provide the trustee with printed certificates for such Notes, in a form eligible for deposit with The Depository Trust Company. 

    (j)  The
Company will comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Shelf Registration and will make
generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a)
of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company's
first fiscal quarter commencing after the effective date of the Shelf Registration Statement, which statement shall cover such 12-month period; provided, that if the Company files the
reports required by this Section 3(j) with the SEC and such reports are publicly available, it shall be deemed to have satisfied its obligation to furnish such reports to its securityholders
pursuant to this Section 3(j). 

    (k) The
Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as
shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder
pursuant to the applicable provisions of the Indenture. 

    (l)  The
Company may require each Holder that proposes to sell Securities pursuant to the Shelf Registration Statement to furnish to the Company a Notice and
Questionnaire containing such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration
Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 

    (m) The
Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if
any, as any Holder shall reasonably request in order to facilitate the disposition of the Securities pursuant to the Shelf Registration. 

    (n) Subject
to the execution of a confidentiality agreement reasonably acceptable to the Company, the Company shall (i) make reasonably available for inspection
by the Holders, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders or any such
underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company's officers, directors, employees, accountants and
auditors to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each
case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided,
however, that the foregoing inspection and information gathering shall be coordinated by one counsel designated by and on behalf of the Initial Purchaser and the Holders as
described in Section 3 hereof. 

    (o) The
Company, if requested by any Notice Holder covered by the Shelf Registration Statement, shall cause (i) its counsel to deliver an opinion and updates
thereof relating to the Securities in customary form addressed to such Notice Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date
of the Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the Company and its
subsidiaries; the qualification of the Company and its subsidiaries to transact business as foreign 

5

 

corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 2(m) hereof; the due authorization, execution, authentication and
issuance, and the validity and enforceability, of the Securities; the absence, to such counsel's knowledge, of material legal or governmental proceedings involving the Company and its subsidiaries;
the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the Securities, or any agreement of the type referred to in
Section 2(m) hereof; the compliance as to form of the Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the
Securities Act and the Trust Indenture Act, respectively; and, as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective
amendment thereto, as the case may be, the absence from the Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by
reference therein of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading
(in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to
execute and deliver all customary documents and certificates and updates thereof reasonably requested by any underwriters of the Securities and (iii) its independent public accountants and the
independent public accountants with respect to any other entity for which
financial information is provided in the Shelf Registration Statement to provide to the Notice Holders and any underwriter therefor a comfort letter in customary form and covering matters of the type
customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of
Auditing Standards No. 72. 

    (p) The
Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities covered by the Shelf Registration
Statement contemplated hereby. 

    3.  Registration Expenses.  (a) Subject to Section 8 hereof, all expenses incident to the
Company's performance of and compliance with this Agreement will be borne by the Company, regardless of whether the Shelf Registration Statement is ever filed or becomes effective, including without
limitation; 

    (i)  all
registration and filing fees and expenses; 

    (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), messenger and delivery services and telephone; 

    (iv) all
fees and disbursements of counsel for the Company; 

    (v) all
application and filing fees in connection with listing the Securities 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 will bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual
audit and the fees and expenses of any person, including special experts, retained by the Company. 

6

 

    (b) In connection with the Shelf Registration Statement required by this Agreement, the Company will reimburse the Initial Purchaser and the Notice Holders of Transfer
Restricted Securities who are selling or reselling Securities pursuant to the "Plan of Distribution" contained in the Shelf Registration Statement for the reasonable fees and disbursements of not more
than one counsel, who shall be Simpson Thacher & Bartlett unless another firm shall be chosen by the Notice Holders of a majority in principal amount of the Transfer Restricted Securities for
whose benefit such Shelf Registration Statement is being prepared. 

    4.  Indemnification.  (a) The Company agrees to indemnify and hold harmless each Notice Holder
and each person, if any, who controls such Notice Holder within the meaning of the Securities Act or the Exchange Act (each Notice Holder and such controlling persons are referred to collectively as
the "Indemnified Parties") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including,
but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act,
the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact
contained in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of, or are based
upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the
Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof;  provided,
however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out
of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or
in any preliminary prospectus relating to the Shelf Registration in reliance upon and in conformity with written information pertaining to such Notice Holder and furnished to the Company by or on
behalf of such Notice Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary
prospectus relating to the Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Notice Holder from whom the person
asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered by such Notice
Holder under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Notice Holder results from the fact that there was not sent or given to such
person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final prospectus if the Company had previously furnished copies thereof to such Notice
Holder; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such
Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange
Act to the same extent as provided above with respect to the indemnification of the Notice Holders of the Securities if requested by such Notice Holders. 

    (b) Each
Notice Holder, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of
the Securities Act or the
Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact
contained in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of or are based
upon the 

7

 

omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or
alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Notice Holder and furnished to the Company by or on behalf of such Notice
Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses
reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity
agreement will be in addition to any liability which such Notice Holder may otherwise have to the Company or any of its controlling persons. 

    (c) Promptly
after receipt by an indemnified party under this Section 4 of notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 4, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof,
the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 4 for any
legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of
such action, and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 

    (d) If
the indemnification provided for in this Section 4 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 exchange of the 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 Notice 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 

8

 

investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 4(d), the Notice Holders shall not be required to
contribute any amount in excess of the amount by which the net proceeds received by such Notice Holders from the sale of the Securities pursuant to the Shelf Registration Statement exceeds the amount
of damages which such Notice 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
agreements contained in this Section 4 shall survive the sale of the Securities pursuant to the Shelf Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 

    5.  Holders' Obligations.  Each Holder agrees, by acquisition of the Transfer Restricted Securities, that
no Holder of Transfer Restricted Securities shall be entitled to sell any of such Transfer Restricted Securities pursuant to a Registration Statement or to receive a prospectus relating thereto,
unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 1(d) hereof and the information set forth in the next sentence. Each Notice Holder
agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any
other information regarding such Notice Holder and the distribution of such Transfer Restricted Securities as the Company may from time to time reasonably request. Any sale of any Transfer Restricted
Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its plan of distribution is as set forth in the prospectus
delivered by such Holder in connection with such disposition, that such prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such
Holder or its plan of
distribution and that such prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the
statements in such prospectus, in the light of the circumstances under which they were made, not misleading. Each Holder agrees that within ten (10) Business Days of any sale, disposition or
other transfer of Securities, whether pursuant to a Registration Statement or exemption from registration under the Securities Act, such Holder shall provide written notice to the Company specifying
the amount of Securities sold, disposed of or transferred and the name and address of the transferree of such Securities. 

    6.  Additional Interest Under Certain Circumstances.  (a) Additional interest (the
"Additional Interest") with respect to the Notes shall be assessed as follows if any of the following events occur (each such event in clauses
(i) through (iv) below being herein called a "Registration Default"): 

	(i)
	the
Shelf Registration Statement required by this Agreement is not filed with the Commission on or prior to the Filing Deadline;

	(ii)
	the
Shelf Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline;

	(iii)
	the
Company fails with respect to a Holder that supplies a Notice and Questionnaire to supplement the Shelf Registration Statement in a timely manner in order to name additional
selling shareholders; or

	(iv)
	the
Shelf Registration Statement required by this Agreement has been declared effective by the Commission but (A) the Shelf Registration Statement thereafter ceases to be
effective or 

9

 

(B) the
Shelf Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified herein (other than
pursuant to Section 1(c) hereof) and (1) the Company fails to cure the Registration Default within five Business Days by a post-effective amendment or a report filed pursuant
to the Exchange Act or (2) if applicable, the Company does not terminate the Deferral Period by the 90th day, as the case may be. 

Each
of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to
operation of law or as a result of any action or inaction by the Commission. 

    Additional
Interest shall accrue daily on the Notes over and above the interest set forth in the title of the Notes from and including the date on which any such Registration Default
shall occur to, but excluding, the date on which all such Registration Defaults have been cured, at a rate of 0.50% per annum for the Notes (the "Additional Interest
Rate") and, if applicable, on an equivalent basis per share (subject to adjustment in the case of stock splits, stock recombinations, stock dividends and the like) of Common
Stock issuable upon conversion of the Notes. 

    (b) A
Registration Default referred to in Section 6(a)(iv) hereof shall be deemed not to have occurred and be continuing in relation to the Shelf
Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to the Shelf
Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared
effective to permit Notice Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in the Shelf Registration Statement or
the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement the Shelf Registration Statement and related
prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of
30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 

    (c) Any
amounts of Additional Interest due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the Notes. The
amount of Additional Interest will be determined by multiplying the applicable Additional Interest Rate by the principal amount of the Notes and further multiplied by a fraction, the numerator of
which is the number of days such Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and
the denominator of which is 360. 

    (d) "Transfer Restricted Securities" means each Security until (i) the date on which such Security has been
effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (ii) the date on which such Security is distributed to the public pursuant
to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act. 

    7.  Rules 144 and 144A.  The Company shall use its best efforts to file the reports required to be
filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder, make
publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any
Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Securities without registration under the Securities Act within the limitation of the
exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Securities
identified to the Company by the Initial Purchaser upon request. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such
requirements. Notwithstanding the foregoing, 

10

 

nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 

    8.  Underwritten Registrations.  If any of the Transfer Restricted Securities covered by the Shelf
Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering ("Managing
Underwriters") will be selected by the Notice Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering
(provided that the Holders of Common Stock issued upon conversion of Notes shall not be deemed Holders of Common Stock, but shall be deemed to be Holders of the aggregate principal amount of Notes
from which such Common Stock was converted). 

    No
person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person's Transfer Restricted Securities on the basis reasonably
provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 

    Notwithstanding
any other provisions of this Agreement to the contrary, the Company shall not be required to pay the expenses of an underwritten offering of Transfer Restricted
Securities pursuant to this Section 8 unless such underwritten offering is for Transfer Restricted Securities in the aggregate principal amount of at least $50,000,000 and shall not be required
to pay any underwriter discount, commission or similar fees related to the sale of the Transfer Restricted Securities. 

    9.  Miscellaneous.  

    (a)  Remedies.  The Company acknowledges and agrees that any failure by the Company to comply with its
obligations under Section 1 hereof may result in material irreparable injury to the Initial Purchaser or 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, the Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the
Company's obligations under Section 1 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. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof. 

    (c)  Amendments and Waivers.  The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the
Transfer Restricted Securities (provided that the Holders of Common Stock issued upon conversion of Notes shall not be deemed Holders of Common Stock, but shall be deemed to be Holders of the
aggregate principal amount of Notes from which such Common Stock was converted) affected by such amendment, modification, supplement, waiver or consents. 

    (d)  Notices.  All notices and other communications provided for or permitted hereunder shall be made in
writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery: 

    (1) if
to a Holder, that is not a Notice Holder, at the most current address given by such Holder to the Company. 

    (2) if
to a Notice Holder, at the most current address given by such Holder to the Company in a Notice and Questionnaire or any amendment thereto.
