      THIS INDENTURE, dated as of November 21, 2005, is between C&D
Technologies, Inc., a Delaware corporation (the "Company"), and The Bank of New
York, a New York banking corporation, as trustee (the "Trustee").

      In consideration of the premises and the purchase of the Securities by the
Holders thereof, the parties hereto agree as follows for the benefit of the
others and for the equal and ratable benefit of the Holders of the Securities.

                                   ARTICLE 1

                   DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.1. Definitions.

      "Additional Interest" has the meaning set forth in Section 5(a) of the
Registration Rights Agreement. Unless the context otherwise requires, all
references herein or in the Securities to "interest" accrued or payable as of
any date shall include, without duplication, any Additional Interest accrued or
payable as of such date as provided in the Registration Rights Agreement.

      "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control"
(including, with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as used with respect to any Person, shall mean
the possession, directly or indirectly, of the power to direct or cause the
direction of the management or policies of such Person, whether through the
ownership of voting securities, by agreement or otherwise.

      "Agent" means any Registrar, Paying Agent, Calculation Agent or Conversion
Agent.

      "Applicable Procedures" means, with respect to any transfer or exchange of
beneficial ownership interests in a Global Security, the rules and procedures of
the Depositary, in each case to the extent applicable to such transfer or
exchange.

      "Applicable Stock Price" on a Trading Day means the Volume-Weighted
Average Price per share of Common Stock (or any security into which the Common
Stock has been converted in connection with a Fundamental Change) on such
Trading Day; provided, however, that if such Volume-Weighted Average Price is
not available, the "Applicable Stock Price" means the market value per share of
the Common Stock on such Trading Day as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company;
provided, however, that for purposes of Section 7.13 hereof, "Applicable Stock
Price" means, in respect of a Conversion Date, the arithmetic average of the
daily Volume-Weighted Average Prices of the Common Stock (or any security into
which the Common Stock has been converted in connection with a Fundamental
Change) over the Cash Settlement Averaging Period.

      "Board of Directors" means either the board of directors of the Company or
any duly authorized committee of such board of directors.

      "Business Day" means each day that is not a Legal Holiday.

      "Cash" means such coin or currency of the United States as at any time of
payment is legal tender for the payment of public and private debts.



      "Cash Settlement Averaging Period" means, in respect of a Conversion Date,
the fifteen consecutive Trading Day period:

            (a) ending on the second Trading Day preceding the Redemption Date,
      if the Company has called the Securities for redemption (regardless of
      whether the Company has irrevocably elected Net Share Settlement);

            (b) ending on the second Trading Day preceding the Final Maturity
      Date, with respect to Conversion Notices received during the period
      beginning 20 Trading Days preceding the Final Maturity Date and ending one
      Trading Day preceding the Final Maturity Date (whether or not the Company
      has irrevocably elected Net Share Settlement);

            (c) beginning on the Trading Day following the Company's receipt of
      a Conversion Notice, if the Company has elected Net Share Settlement and
      has not previously called the Securities for redemption; provided,
      however, that if the Company has elected Net Share Settlement and the
      Company receives a Conversion Notice during the period beginning 20
      Trading Days preceding the Final Maturity Date and ending one Trading Day
      preceding the Final Maturity Date, the Cash Settlement Averaging Period
      for such Securities shall end on the second Trading Day preceding the
      Final Maturity Date; and

            (d) beginning on the Trading Day following the final Trading Day of
      the Conversion Retraction Period, in all other cases.

      "Certificated Security" means a Security that is in substantially the form
attached hereto as Exhibit A and that does not include the information or the
schedule called for by footnotes 1 and 5 thereof.

      "Closing Sale Price" of the Common Stock on any Trading Day means the
closing sale price per share (or if no closing sale price is reported, the
average of the bid and ask prices or, if there is more than one bid or ask
price, the average of the average bid and the average ask prices) on such
Trading Day as reported in composite transactions on the NYSE or, if the Common
Stock is not listed on the NYSE, on the principal United States securities
exchange on which the Common Stock is then traded or, if the Common Stock is not
listed on a United States national or regional securities exchange, as reported

            (j) unless context otherwise requires, any reference to an "Article"
      or a "Section" refers to an Article or Section, as the case may be, of
      this Indenture; and

            (k) "or" is not exclusive.

                                   ARTICLE 2

                                 THE SECURITIES

Section 2.1. Form and Dating

      (a) The Securities and the corresponding 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, exchange
rule, Applicable Procedures or usage. The Company shall provide any such
notations, legends or endorsements to the Trustee in writing. Each Security
shall be dated the date of its authentication.

      The terms and provisions contained in the Securities shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby; provided, however, to the
extent permitted by applicable law, if any provision of any Security conflicts
with the express provisions of this Indenture, the provisions of this Indenture
shall govern and be controlling.

      (b) Restricted Global Securities. All of the Securities shall be issued
initially in the form of one or more Restricted Global Securities, which shall
be deposited on behalf of the purchasers of the Securities represented thereby
with the Securities Custodian, as custodian for the depositary, The Depository
Trust Company (such depositary, or any successor thereto, being hereinafter
referred to as the "Depositary"), and registered in the name of its nominee,
Cede & Co., or as otherwise instructed by the Depositary, duly executed by the
Company and authenticated by the Trustee as hereinafter provided. The aggregate
principal amount of the Restricted Global Securities may from time to time be
increased or decreased by adjustments made on the records of the Securities
Custodian and the Depositary as hereinafter provided, subject in each case to
compliance with the Applicable Procedures and the provisions of this Indenture.

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


                                      -9-


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

      The Company shall issue and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), authenticate and deliver
in accordance with Section 2.2, initially one or more Global Securities that (i)
shall be registered in the name of Cede & Co. or as otherwise instructed by the
Depositary, (ii) shall be delivered by the Trustee to the Depositary or to the
Securities Custodian pursuant to the Depositary's instructions and (iii) shall
bear legends required for Global Securities as set forth in Exhibit A hereto.

      (d) Book Entry Provisions. 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 the 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 (A) prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary, or such nominee, as the case may be, or (B) impair, as between
the Depositary and its Agent Members, the Applicable Procedures or the operation
of customary practices governing the exercise of the rights of a Holder of any
Security.

      None of the Company, the Trustee, the Registrar, any Paying Agent or any
agent of any of them shall have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests in the Securities, for maintaining, supervising or reviewing any
records relating to such beneficial owner interests, or for any acts or
omissions of a Depository or for any transactions between a Depository and any
beneficial owner or between or among beneficial owners. No owner of a beneficial
interest in the Securities shall have any rights under this Indenture, and the
Depository or its nominee, if any, shall be deemed and treated by the Company,
the Trustee, the Registrar, any Paying Agent or any agent of any of them as the
absolute owner and holder of such Securities for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee, the Registrar, any Paying Agent or any agent of any of them from giving
effect to any written certification, proxy or other authorization furnished by a
Depository, or any of its members and any other Person on whose behalf such
member may act, the operation of customary practices of such Persons governing
he exercise of the rights of a beneficial owner of any Securities.

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

Section 2.2. Execution and Authentication

      (a) A duly authorized Officer of the Company shall sign the Securities for
the Company by manual or facsimile signature.

      (b) If an Officer of the Company 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.


                                      -10-


      (c) 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.

      (d) The Trustee shall authenticate and make available for delivery
Securities for original issue in the aggregate principal amount of up to
$75,000,000 upon receipt of a written order or orders of the Company signed by
an Officer of the Company (a "Company Order"). The aggregate principal amount of
Securities outstanding at any time may not exceed $75,000,000 except as provided
in Section 2.7.

      (e) 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 principal amount and any integral multiple
thereof.

Section 2.3. Registrar, Paying Agent and Conversion Agent

      The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar"), an office
or agency in the Borough of Manhattan, the City of New York, where Securities
may be presented for redemption, purchase or payment ("Paying Agent"), an office
or agency where Securities may be presented for conversion ("Conversion Agent")
and an office or agency where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Registrar shall
keep a register of the Securities ("Register") and of their transfer and
exchange.

      The Company may have one or more co-registrars, one or more additional
paying agents, and one or more additional conversion agents. The term
"Registrar" includes any co-registrar, including any named pursuant to Section
9.6. The term "Paying Agent" includes any additional paying agent, including any
named pursuant to Section 9.6. The term "Conversion Agent" includes any
additional conversion agent, including any named pursuant to Section 9.6.

      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 or 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.

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

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

      Prior to 10:00 a.m., New York City time, on each due date of payments in
respect of, or delivery of Common Stock, Cash or other consideration or any
combination thereof, as applicable and as provided herein, upon conversion of,
any Security, the Company shall deposit with the Paying Agent Cash (in
immediately available funds if deposited on the due date) and/or with the
Conversion Agent such number of shares of Common Stock and/or other
consideration sufficient to make such payments or deliveries when


                                      -11-


so becoming due. The Company shall require each Paying Agent or Conversion
Agent, as applicable (other than the Trustee), to agree in writing that such
Agent shall hold in trust for the benefit of Securityholders or the Trustee all
Cash, Common Stock and/or other consideration, as applicable, held by such Agent
for the making of payments or deliveries in respect of the Securities and shall
notify the Trustee in writing of any default by the Company in making any such
payment or delivery. If the Company or an Affiliate of the Company acts as
Paying Agent or Conversion Agent, as applicable, it shall segregate the Cash,
Common Stock and other consideration, as applicable, held by it as Paying Agent
or Conversion Agent, as applicable, and hold it as a separate trust fund.

      The Company at any time may require a Paying Agent or Conversion Agent, as
applicable, to pay all Cash, Common Stock or other consideration, as applicable,
held by it to the Trustee, and the Trustee may at any time during the
continuance of any Default, upon written request to the Paying Agent or the
Conversion Agent, as applicable, require such Paying Agent or Conversion Agent,
as applicable, to pay forthwith to the Trustee all Cash, Common Stock or other
consideration, as applicable, so held in trust by such Paying Agent or
Conversion Agent. Upon doing so, the Paying Agent or the Conversion Agent, as
applicable, shall have no further liability for such Cash, Common Stock or other
consideration, as applicable.

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
the Securityholders. If the Trustee is not the Registrar, the Company shall
furnish to the Trustee on or before each Interest Payment Date, and at such
other times as the Trustee may request in writing, a list of the names and
addresses of the Securityholders in such form and as of such date as the Trustee
may reasonably request.

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, if such Security is a Certificated Security, be duly
endorsed or accompanied by an assignment form, in the form included in Exhibit A
attached hereto and, if applicable, a transfer certificate, in the form included
in Exhibit B attached hereto, and in form reasonably 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, assessment or other governmental charge that may be imposed in
relation thereto, other than exchanges pursuant to Section 2.10, Section 13.5,
Article 3, Article 5 or Article 7, in each case, not involving any transfer.

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


                                      -12-


      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 or Section 9.6 hereof
shall provide to the Trustee such information as the Trustee may reasonably
request in connection with the delivery by such Registrar of Securities upon
transfer or exchange of Securities.

      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 opinions of counsel, 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 (including if so requested by the
Company exercising a right to require the delivery of such items), and to
examine the same to determine substantial compliance as to form with the express
requirements hereof.

      Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book-entry system maintained by the Depository
(or its agent), and that ownership of a beneficial interest in a Global Security
shall be required to be reflected in a book-entry system.

Section 2.7. Replacement Securities

      If (a) any mutilated security is surrendered to the Company, a Registrar
or the Trustee, or (b) the Company, the Registrar and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Security, and, in either case, there is delivered to the Company, the Registrar
and the Trustee such security or indemnity as shall be reasonably 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 or protected purchaser, the Company shall issue, and the Trustee
shall, upon receipt of a Company Order (which the Company agrees to deliver
promptly), 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 pursuant to
Article 3 or purchased by the Company pursuant to Article 5, the Company in its
discretion may, instead of issuing a new Security, pay, redeem or purchase such
Security, as the case may be, in accordance herewith.

      Upon the issuance of any new Securities under this Section 2.7, the
Company may require the payment of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in relation thereto and any
other 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
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued and outstanding
hereunder.


                                      -13-


      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 outstanding at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those paid, redeemed or repurchased
pursuant to Section 2.7, those delivered to it for cancellation and those
described in this Section 2.8 as not outstanding.

      If a Security is replaced pursuant to Section 2.7 (other than a mutilated
Security surrendered for replacement), it ceases to be outstanding unless the
Trustee receives, subsequent to the new Security's authentication, proof
satisfactory to the Company that the replaced Security is held by a bona fide or
protected purchaser. A mutilated Security ceases to be outstanding upon
surrender and replacement thereof pursuant to Section 2.7.

      If the Paying Agent holds, in accordance with the terms of this Indenture,
prior to 10:00 a.m., New York City time, on the Final Maturity Date or a
Redemption Date or on a Put Purchase Date, as the case may be, Cash sufficient
to pay all Securities then payable, then on and after such Final Maturity Date,
Redemption Date or Put Purchase Date, as the case may be, such Securities shall
cease to be outstanding and interest on such Securities shall cease to accrue.

      If a Security is converted in accordance with Article 7, then on the
Conversion Date, such Security shall cease to be outstanding and interest on
such Security shall cease to accrue, unless there shall be a default in the
delivery of the consideration payable hereunder upon such conversion.

      Subject to the restrictions contained in Section 2.9, a Security does not
cease to be outstanding solely 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 given or concurred in any notice, request, demand,
authorization, 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 and deemed not to be outstanding for
such purposes, except that, for purposes of determining whether the Trustee
shall be protected in relying on any such notice, request, demand,
authorization, direction, waiver or consent, only Securities which a Trust
Officer actually knows are so 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, and is not acting on
the behalf of, 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 reasonably considers appropriate for
temporary Securities. After the preparation of definitive Securities, the
temporary Securities shall be exchangeable for definitive Securities upon
surrender of the temporary Securities at the office or agency of the Company
designated for such purpose pursuant to Section 2.3, without charge to the
Holder. Upon surrender for cancellation


                                      -14-


of any one or more temporary Securities, the Company shall execute and the
Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations. Until so
exchanged the temporary Securities shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities.

Section 2.11. 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, redemption, 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. The
Company may not issue new Securities to replace Securities that it has paid or
delivered to the Trustee for cancellation or that any Holder has converted
pursuant to Article 7.

      All Securities that are redeemed or purchased pursuant to Articles 3 or 5
or otherwise acquired by the Company shall be delivered to the Trustee for
cancellation. If the Company shall acquire any of the Securities, such
acquisition shall not operate as a repurchase or satisfaction of the
indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

Section 2.12. Legend; Additional Transfer and Exchange Requirements

      (a) Transfer and Exchange of Global Securities.

      (i) Certificated Securities shall be issued in exchange for interests in
the Global Securities only (x) if 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 of such notice or (y) if an Event of
Default has occurred and is continuing, each in accordance with the Applicable
Procedures. In any such case, the Company shall execute, and the Trustee shall,
upon receipt of a Company Order (which the Company agrees to deliver promptly),
authenticate and deliver Certificated Securities in an aggregate principal
amount equal to the principal amount of such Global Securities in exchange
therefor. Only Restricted Certificated Securities shall be issued in exchange
for beneficial interests in Restricted Global Securities, and only Unrestricted
Certificated Securities shall be issued in exchange for beneficial interests in
Unrestricted Global Securities. Certificated Securities issued in exchange for
beneficial interests in Global Securities shall be registered in such names and
shall be in such authorized denominations as the Depositary, pursuant to
instructions from its Agent Members or otherwise in accordance with the
Applicable Procedures, shall instruct the Trustee. The Trustee shall deliver or
cause to be delivered such Certificated Securities to the Persons in whose name
such Securities are so registered. Such exchange shall be effected in accordance
with the Applicable Procedures. In the event that the Certificated Securities
are not issued to each such beneficial owner promptly after the Registrar has
received a request from the Depositary to issue such Certificated Securities,
the Company expressly acknowledges, with respect to the right of any Holder to
pursue a remedy pursuant to Section 11.6 or 11.7 hereof, the right of any
beneficial holder of Securities to pursue such remedy with respect to the
portion of the Global Security that represents such Beneficial Owner's
Securities as if such Certificated Notes had been issued.

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


                                      -15-


Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

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

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

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

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

            (i) shall be duly endorsed or accompanied by a written instrument of
      transfer in accordance with the proviso to the first sentence 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:

                  (1) 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 Exhibit B);

                  (2) if such Restricted Certificated Security is being
            transferred to a person the Holder reasonably believes is a QIB in
            accordance with Rule 144A, or pursuant to an effective registration
            statement under the Securities Act or in compliance with Rule 904 of
            Regulation S under the Securities Act, a certification to that
            effect from such Holder (in substantially the form set forth in
            Exhibit B);

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

      (c) Transfer of a Beneficial 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


                                      -16-


in such form as is customary for the Depositary from the Depositary or its
nominee on behalf of the Person having such beneficial interest in the
Restricted Global Security (all of which may be submitted by facsimile or
electronically):

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

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

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

      (d) Transfer of a Beneficial Interest in an Unrestricted Global Security
for a Beneficial Interest in a Restricted Global Security. Any person having a
beneficial interest in an Unrestricted Global Security may upon request, subject
to the Applicable Procedures, transfer such beneficial interest to a person who
is required or permitted to take delivery thereof in the form of a beneficial
interest in 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 Depository or its nominee on behalf of any person having a
beneficial interest in an Unrestricted Global Security and the following
additional information and documents in such form as is customary for the
Depositary, from the Depositary or its nominee on behalf of the person having
such beneficial interest in the Unrestricted Global Security (all of which may

                  144, a certification to that effect from such Holder (in
                  substantially the form set forth in Exhibit B) and, if the

                  effect from such Holder (in substantially the form set forth
                  in Exhibit B); or

                        (2) if such Restricted Certificated Security is being

                  from such Holder (in substantially the form set forth in

                  reasonably acceptable to the Company and the Registrar to the
                  effect that such transfer does not require registration under
                  the Securities Act; or

                        (4) if such Unrestricted 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 Exhibit B).

      (f) Legends.

      (i) Except as permitted by the following paragraphs (ii), (iii) and (iv),
each Global Security and Certificated Security (and all Securities issued in
exchange therefor or upon registration of transfer or


                                      -19-


replacement thereof) shall bear a legend in substantially the form called for by
footnote 2 to Exhibit A attached hereto (the "Restricted Legend"), for so long
as it is required by this Indenture to bear such legend.

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

                  (1) in the case of any Restricted Certificated Security, each
            Registrar shall permit the Holder thereof to transfer such
            Restricted Certificated Security to a transferee who, unless such
            transferee is an Affiliate of the Company, shall take such Security
            in the form of an Unrestricted Certificated Security or (under the
            circumstances described in Section 2.12(e)) 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

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

If the Registrar so requests or if the Applicable Procedures so require, prior
to the removal of any restrictive legend at the end of the holding period
applicable to sales of the Securities under Rule 144(k) of the Securities Act,
such requesting Holder shall deliver an Opinion of Counsel in form reasonably
acceptable to the Registrar and the Company to the effect that the restrictions
on transfer contained herein and the restrictive legend are no longer required
in order to maintain compliance with the Securities Act.

      (iii) Upon the exchange, registration of transfer or replacement of
Securities not bearing the Restricted Legend, the Company shall issue, and the
Trustee shall, upon receipt of a Company Order (which the Company agrees to
deliver promptly), authenticate and deliver, Securities that do not bear such
Restricted Legend.

      (iv) After the expiration of the holding period pursuant to Rule 144(k) of
the Securities Act, the Company may with the consent of any Holder of a
Restricted Global Security or a Restricted Certificated Security that is not an
Affiliate of the Company, remove any restriction of transfer on such Security,
and the Company shall issue, and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), authenticate and deliver
Securities that do not bear the Restricted Legend.

      (v) Until the expiration of the holding period applicable to sales of the
Securities under Rule 144(k) of the Securities Act or a transfer pursuant to
Rule 144 or pursuant to an effective registration statement under the Securities
Act, the shares of Common Stock issued upon conversion of the Securities shall
bear a legend substantially to the same effect as the Restricted Legend;
provided that all Securities held by Affiliates of the Company shall bear the
Restricted Legend at all times.


                                      -20-


      (g) Transfers to the Company. Nothing contained in this Indenture or in
the Securities shall prohibit the sale or other transfer of any Securities
(including beneficial interests in Global Securities) to the Company, or any of
its Subsidiaries or any of its Affiliates.

Section 2.13. CUSIP Numbers

      The Company in issuing the Securities may use one or more "CUSIP," "ISIN"
or other similar numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP," "ISIN" or other similar numbers in notices of redemption or
purchase as a convenience to Holders; provided, however, that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption 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 shall promptly notify the Trustee of any change in the "CUSIP," "ISIN"
or other similar numbers.

Section 2.14. Ranking

      The obligations of the Company arising under or in connection with this
Indenture and every outstanding Security issued under this Indenture from time
to time constitutes and shall constitute a senior unsecured general obligation
of the Company, ranking equally with existing and future senior unsecured
indebtedness of the Company and ranking senior in right of payment to any future
indebtedness of the Company that is expressly made subordinate to the Securities
by the terms of such indebtedness.

Section 2.15. Persons Deemed Owners

      Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of, Redemption Price or Put
Price, and interest on the Security, for the purpose of receiving Common Stock,
Cash and, if applicable, any Make-Whole Premium upon conversion and for all
other purposes whatsoever, whether or not such Security is overdue, and none of
the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. The registered Holder of a Global Security
may grant proxies and otherwise authorize any person, including Agent Members
and persons that may hold interests through Agent Members, to take any action
that a Holder is entitled to take under this Indenture or the Securities.

Section 2.16. Defaulted Interest

      If the Company defaults on a payment of interest on the Securities, it
shall pay the defaulted interest, plus (to the extent permitted by law) any
interest payable on the defaulted interest, in accordance with the terms hereof,
to the Persons who are Holders on a subsequent special record date, which date
shall be at least five Business Days prior to the payment date. The Company
shall fix such special record date and payment date in a manner satisfactory to
the Trustee. At least 10 days before such special record date, the Company shall
mail to each Holder a notice that states the special record date, the payment
date and the amount of defaulted interest, and interest payable on defaulted
interest, if any, to be paid. The Company may make payment of any defaulted
interest in any other lawful manner not inconsistent with the requirements (if
applicable) of any securities exchange on which the Securities may be listed
and, upon such notice as may be required by such exchange, if, after written
notice given by the Company to the Trustee of the proposed payment pursuant to
this sentence, such manner of payment shall be deemed practicable by the
Trustee.

                                   REDEMPTION

Section 3.1. Redemption of Securities; Notice to Trustee

      (a) At any time on and after November 1, 2010 and before November 1, 2012,
the Securities may be redeemed at the option of the Company in whole or in part
as described below, if in the previous 30 consecutive Trading Days ending on the
Trading Day before the date of the mailing of the Notice of Redemption the
Closing Sale Price of the Common Stock exceeds 130% of the Conversion Price for
at least 20 Trading Days. Upon any redemption pursuant to this Section 3.1, the
Company shall provide the notice required by Section 3.3 hereof (which notice
may be revoked at any time prior to the time at which the Company or the
Trustee, as the case may be, has given such notice to Securityholders) and shall
pay a redemption price in Cash equal to 100% of the principal amount of the
Securities being redeemed, plus any accrued and unpaid interest (including
Additional Interest, if any) to, but excluding, the date fixed for redemption,
payable in Cash (the "Redemption Price").

      (b) At any time on and after November 1, 2012, the Securities may be
redeemed at any time or from time to time at the option of the Company in whole
or in part at the Redemption Price.

      (c) In the event that the Company elects to redeem the Securities on a
Redemption Date that is after any Interest Payment Record Date but on or before
the corresponding Interest Payment Date or that results in the conversion of the
Securities prior to that Interest Payment Date, the Company shall be required to
pay any accrued and unpaid interest to the same Holder to whom the Company pays
the principal of such Security regardless of whether such Holder was the
registered Holder on the Interest Payment Record Date immediately preceding such
Redemption Date and, if the Holder to whom the Company pays the principal and
interest was not the registered Holder on the Interest Payment Record Date, such
payment of interest shall be in lieu of payment to the registered Holder on such
Interest Payment Record Date.

      (d) If the Company elects to redeem Securities pursuant to this Section
3.1 and paragraph 5 of the Securities, it shall notify the Trustee of the
Redemption Date and the principal amount of Securities to be redeemed at least
15 days prior to the date notice of the Redemption Date is given to the Holders
pursuant to Section 3.3 (unless a shorter notice shall be satisfactory to the
Trustee).

Section 3.2. Selection of Securities to be Redeemed

      If less than all of the Securities are to be redeemed, unless the
Applicable Procedures provide otherwise, the Trustee shall select the Securities
to be redeemed. The Trustee shall make the selection by lot, on a pro rata basis
or by any other method the Trustee considers fair and appropriate or in
accordance with the Applicable Procedures to the extent the Securities are
issued as Global Securities. Securities in denominations of $1,000 principal
amount may only be redeemed in whole. The Trustee may select for redemption
portions (equal to $1,000 principal amount or any integral multiple thereof) of
the principal of Securities that have denominations larger than $1,000 principal
amount. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The
Trustee shall notify the Company promptly of the Securities or portions of the
Securities to be redeemed.

      Securities and portions of Securities that are to be redeemed are
convertible by the Holder until 5:00 p.m., New York City time, on the Business
Day immediately preceding the Redemption Date. If any Security selected for
partial redemption is converted in part before termination of the conversion
right with respect to the portion of the Security so selected, the converted
portion of such Security shall be


                                      -22-


deemed to be taken from the portion selected for redemption. Securities that
have been converted subsequent to the Trustee commencing selection of Securities
to be redeemed but prior to redemption of such Securities shall be treated by
the Trustee as outstanding for the purpose of such selection.

Section 3.3. Notice of Redemption

      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 in accordance with Section 16.2.

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

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                  (3) the then current Conversion Rate;

                  (4) the names and addresses of the Paying Agent and Conversion
            Agent;

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

                  (6) that Holders who wish to convert Securities must surrender
            such Securities for conversion prior to 5:00 p.m., New York City
            time, on the Business Day immediately preceding the Redemption Date
            and must satisfy the other requirements set forth in paragraph 8 of
            the Securities and Article 7 hereof;

                  (7) that, unless the Company defaults in making the payment of
            the Redemption Price, interest on Securities called for redemption
            shall cease accruing on and after the Redemption Date;

                  (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 shall be issued; and

                  (9) whether, with respect to Securities converted during the
            period between the date of mailing of the Notice of Redemption and
            the Redemption Date, the Company will satisfy its Conversion
            Obligation in Cash, in shares of Common Stock or a combination of
            both.

      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 Applicable Procedures applicable to redemptions.

      At the Company's written request, the Trustee shall give the notice of
redemption to each Holder in the Company's name and at the Company's expense;
provided, however, that the Company makes such request at least three Business
Days (unless a shorter period shall be satisfactory to the Trustee) prior to the
date by which such notice of redemption must be given to Holders in accordance
with this Sec-


                                      -23-


tion 3.3; provided further, however, that the text of the notice of redemption
shall be prepared by the Company.

Section 3.4. Effect of Notice of Redemption

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

Section 3.5. Deposit of Redemption Price

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

      If the Paying Agent holds, in accordance with the terms hereof, at 10:00
a.m., New York City time, on the applicable Redemption Date, Cash sufficient to
pay the Redemption Price of all Securities to be redeemed on such date, then, on
and after such Redemption Date, such Securities shall cease to be outstanding
and interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their Holders to the Paying Agent, and the rights of
the Holders in respect thereof shall terminate (other than the right to receive
the Redemption Price upon delivery of such Securities by their Holders to the
Paying Agent).

Section 3.6. Securities Redeemed in Part

      Any Certificated Security that is to be redeemed only in part shall be
surrendered at the office of the Paying Agent and, promptly after the Redemption
Date, the Company shall issue and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), 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
redeemed.

Section 3.7. Repayment to the Company

      To the extent that the aggregate amount of Cash deposited by the Company
pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Securities
or portions thereof that the Company is obligated to redeem on the Redemption
Date (because of the conversion of Securities pursuant to Article 7 or
otherwise) then, promptly after the Redemption Date, the Paying Agent shall
return any such excess Cash to the Company.

Section 5.1. Purchase of Securities at Option of the Holder upon a Fundamental
Change

      (a) In the event a Fundamental Change shall occur at any time when any
Securities remain outstanding, the Securities shall be purchased by the Company,
at the option of any Holder thereof, in accordance with the provisions of
paragraph 6 of the Securities on a date specified by the Company (the
"Fundamental Change Purchase Date") that is not less than 20 nor more than 45
Business Days after the date the Company mails the Fundamental Change Company
Notice pursuant to Section 5.1(b), at a purchase price in Cash equal to 100% of
the principal amount of the Securities tendered for purchase, plus accrued and
unpaid interest (including Additional Interest, if any) to, but not including,
the Fundamental Change Purchase Date (the "Fundamental Change Purchase Price"),
subject to satisfaction by or on behalf of any Holder of the requirements set
forth in Section 5.1(c).

      A "Fundamental Change" shall be deemed to have occurred upon the
occurrence of any of the following:

                  (1) any "person" or "group" files a Schedule 13D or Schedule
            TO, or any successor schedule, form or report under the Exchange
            Act, disclosing, or the Company otherwise becomes aware, that such
            person or group is or has become the "beneficial owner," directly or
            indirectly, of shares of the Company's voting Stock representing 50%
            or more of the total voting power of all outstanding classes of the
            Company's voting Stock or has the power, directly or indirectly, to
            elect a majority of the members of the "board of directors" of the
            Company;

                  (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
            Company's assets, 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 (the "Existing Shareholders") that
            "beneficially owned," directly or indirectly, shares of the
            Company's voting stock immediately prior to such transaction
            beneficially own, directly or indirectly, shares of voting stock
            representing a majority of the total voting power of all outstanding
            classes of voting stock of the surviving or transferee person in
            substantially the same proportion amongst such Existing Shareholders
            as such ownership immediately prior to such transaction;

                  (3) a majority of the members of the "board of directors" of
            the Company are not continuing directors; or

                  (4) the Company's Common Stock ceases to be listed on the NYSE
            or another national securities exchange and is not then quoted on
            The Nasdaq National Market or another established automated
            over-the-counter trading market in the United States.

            Notwithstanding anything to the contrary set forth in this Section
      5.1, a merger or consolidation shall be deemed not to constitute a
      Fundamental Change if substantially all of the con-


                                      -25-


      sideration (excluding Cash payments for fractional shares and Cash
      payments pursuant to dissenters' appraisal rights) in the merger or
      consolidation constituting the Fundamental Change consists of common stock
      traded on the NYSE or another national securities exchange or quoted on
      The Nasdaq National Market (or which shall be so traded or quoted when
      issued or exchanged in connection with such merger or consolidation) and
      as a result of such transaction or transactions the Securities become
      convertible solely into shares of such common stock.

            For purposes of this Section 5.1:

            o     "person" and "group" shall have the meanings given to them for
                  purposes of Sections 13(d) and 14(d) of the Exchange Act or
                  any successor provisions, and the term "group" includes any

                  under the Exchange Act, or any successor provision;

            o     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;

Agent).

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 5.6. Repayment to the Company

      To the extent that the aggregate amount of Cash deposited by the Company
pursuant to Section 5.3 exceeds the aggregate Put Price of the Securities or
portions thereof that the Company is obligated to purchase on the Put Purchase
Date, then, promptly after the Put Purchase Date, the Paying Agent shall return
any such excess Cash to the Company.

Section 5.7. Compliance with Securities Laws upon Purchase of Securities

      When complying with the provisions of Article 5 hereof (provided that such
offer or purchase constitutes an "issuer tender offer" for purposes of Rule
13e-4 (which term, as used herein, includes any successor provision thereto)
under the Exchange Act at the time of such offer or purchase), and subject to
any exemptions available under applicable law, the Company shall:

            (a) comply with Rule 13e-4, Rule 14e-1 and any other tender offer
      rules under the Exchange Act that may then be applicable; and

            (b) otherwise comply with all federal and state securities laws so
      as to permit the rights and obligations in connection with any purchase
      pursuant to this Article 5 to be exercised in the time and in the manner
      specified herein.

                                   ARTICLE 6

                               MAKE-WHOLE PREMIUM

Section 6.1. Make-Whole Premium

      (a) If a Fundamental Change occurs prior to November 1, 2012, the Company
shall pay the Make-Whole Premium to Holders of the Securities who convert their
Securities on a Conversion Date that falls within a period that (i) begins at
the opening of business on the date (the "Effective Notice Date") the
Fundamental Change Company Notice with respect to such Fundamental Change is
mailed in


                                      -32-


accordance with Section 5.1(b) and (ii) ends at the close of business on the
second Trading Day immediately preceding the Fundamental Change Purchase Date
corresponding to such Fundamental Change. The Make-Whole Premium shall be paid
to such Holders on such Fundamental Change Purchase Date. The Make-Whole Premium
will be in addition to, and not in substitution for, any Cash, securities or
other assets otherwise due to Holders of Securities upon conversion as provided
in this Indenture.

      (b) The Make-Whole Premium with respect to a Fundamental Change shall be
determined by reference to the Make-Whole Premium Table and is based on the
Effective Date of such Fundamental Change and the Stock Price with respect to
such Fundamental Change.

            (i) "Effective Date" with respect to a Fundamental Change means the
      date that such Fundamental Change becomes effective.

            (ii) "Stock Price" with respect to a Fundamental Change means the
      price paid (or deemed to be paid) per share of Common Stock in the
      transaction constituting such Fundamental Change, determined as follows:

                  (1) if holders of the Common Stock receive only Cash in such
            Fundamental Change, the Stock Price shall be the Cash amount paid
            per share of Common Stock; or

                  (2) otherwise, the Stock Price shall be the average of the
            Applicable Stock Prices for the five consecutive Trading Days
            beginning on the second Trading Day after the Effective Notice Date
            with respect to such Fundamental Change (which average shall be
            appropriately adjusted by the Board of Directors, in its good faith
            determination (which determination shall be described in a
            resolution of the Board of Directors), to account for any
            adjustment, pursuant hereto, to the Conversion Rate that shall
            become effective, or any event requiring, pursuant hereto, an
            adjustment to the Conversion Rate where the "ex" date of such event
            occurs, at any time during such five consecutive Trading Days).

                  (iii) "Make Whole Premium" means, with respect to a
            Fundamental Change, the percentage set forth on the table below (the
            "Make Whole Premium Table") for the Stock Price and the Effective
            Date of such Fundamental Change:

provided, however, that:

                  (1) if at any time the Conversion Rate shall be adjusted
            pursuant to this Indenture, then, on the date and at the time such
            adjustment is so required to be made pursuant hereto, each price set
            forth in the Make-Whole Premium Table above under the column titled
            "Stock Price" shall be deemed to be adjusted so that such price, at
            and after such time, shall be equal to the product of (1) such price
            as in effect immediately before such adjustment to such price and
            (2) a fraction whose numerator is the Conversion Rate in effect
            immediately before such adjustment to the Conversion Rate and whose
            denominator is the Conversion Rate to be in effect, in accordance
            herewith, immediately after such adjustment to the Conversion Rate;

                  (2) if the Stock Price is between two Stock Prices on the
            Make-Whole Premium Table or the Effective Date is between two
            Effective Dates on the Make-Whole Premium Table, the Make-Whole
            Premium shall be determined by straight-line interpolation between
            the Make-Whole Premium amounts set forth for the higher and lower
            Stock Prices and the two Effective Dates, as applicable, based on a
            365-day year;

                  (3) if the Stock Price is equal to or in excess of $40.00 per
            share (subject to adjustment in the same manner as the Stock Price
            as set forth in Section 6.1(b)(iii)(1)) the Make-Whole Premium will
            be as set forth in the bottom row of the table; and

                  (4) if the Stock Price is less than $7.00 per share (subject
            to adjustment in the same manner as the Stock Price as set forth in
            Section 6.1(b)(iii)(1)), the Make-Whole Premium shall be deemed to
            be equal to zero.

            (iv) The Make-Whole Premium payable on a Security with respect to a
      Fundamental Change shall have a value (determined in accordance with
      Section 6.1(d)) equal to the product of (1) the principal amount of such
      Security and (2) the Make-Whole Premium with respect to such Fundamental
      Change.

      (c) The Make-Whole Premium with respect to a Fundamental Change shall be
paid solely in shares of Common Stock (other than Cash paid in lieu of
fractional shares); provided, however, that if, in connection with such
Fundamental Change, all or substantially all of the shares of Common Stock have
been converted into or exchanged for Cash, other securities or other property,
then such Make-Whole Premium shall be paid in the same form of consideration
into which all or substantially all of the shares of Common Stock have been
converted or exchanged in connection with such Fundamental Change (other than
Cash paid in lieu of fractional interests in any security or pursuant to
dissenters' rights), in accordance herewith; provided, further, that if holders
of the Common Stock receive or have the right to receive more than one form of
consideration in connection with such Fundamental Change, then, for purposes of
the immediately preceding proviso, the forms of consideration in which the
Make-Whole Pre-


                                      -34-


mium shall be paid shall be in proportion to the relative value, determined in
accordance with Section 6.1(d), of the different forms of consideration paid to
holders of Common Stock in connection with such Fundamental Change; provided
further, that, in all cases, any fractional interests in any security (including
Common Stock) or other property constituting a portion of the Make-Whole Premium
payable to a Holder shall be paid exclusively in Cash (such fractional interest
to be valued in accordance with Section 6.1(d)).

      (d) The value of the shares of Common Stock or other consideration for
purposes of determining the number of shares of Common Stock or other
consideration to be issued or delivered, as the case may be, in respect of a
Make-Whole Premium with respect to a Fundamental Change shall be calculated as
follows:

            (i) in the case such Fundamental Change is a transaction in which
      all or substantially all of the shares of Common Stock have been, as of
      the Effective Date of such Fundamental Change, converted into or exchanged
      for the right to receive securities or other assets or property (including
      Cash), the consideration shall be valued as follows:

                  (1) securities that are traded on the NYSE or other U.S.
            national securities exchange or approved for quotation on Nasdaq or
            any similar system of automated dissemination of quotations of
            securities prices shall be valued at 98% of the average of the
            volume-weighted average prices of such securities (determined in the
            same manner in which the Volume-Weighted Average Price is calculated
            in accordance herewith; provided, however, that if such
            volume-weighted average prices are not available, then the closing
            sales prices of such securities (determined in the same manner in
            which the Closing Sale Price is calculated in accordance herewith)
            on such exchange or system shall instead be used) for the five
            consecutive Trading Days beginning on the second Trading Day after
            the Effective Notice Date of such Fundamental Change; provided,
            however, that the Board of Directors shall, in its good faith
            determination (which determination shall be described in a
            resolution of the Board of Directors), make appropriate adjustments
            to account for any event that, assuming such securities were Common
            Stock, would require, pursuant hereto, an adjustment to the
            Conversion Rate to become effective, or any such event whose "ex"
            date occurs, at any time during such five consecutive Trading Days,

                  (2) other securities, assets or property (other than Cash)
            shall be valued at 98% of the average of the fair market value of
            such securities, assets or property (other than Cash) as of the
            close of business on the sixth Trading Day after the Effective
            Notice Date of such Fundamental Change, as determined by two
            independent nationally recognized investment banks selected by the
            Company, and

                  (3) 100% of any Cash.

            (ii) in all other cases, the value of each share of Common Stock
      shall equal 98% of the average of the Applicable Stock Prices per share of
      Common Stock for the five consecutive Trading Days beginning on the second
      Trading Day after the Effective Notice Date of such Fundamental Change,
      which average shall be appropriately adjusted by the Board of Directors,
      in its good faith determination (which determination shall be described in
      a resolution of the Board of Directors), to account for any adjustment,
      pursuant hereto, to the Conversion Rate that shall become effective, or
      any event requiring, pursuant hereto, an adjustment to the Conversion Rate
      where the "ex" date of such event occurs, at any time during such five
      consecutive Trading Days.


                                      -35-


      (e) A calculation agent appointed from time to time by the Company (the
"Calculation Agent") shall, on behalf of and on request by the Company,
calculate (A) the Stock Price and (B) the Make-Whole Premium with respect to
such Stock Price, based on the Effective Date specified by the Company, and
shall deliver its calculation of the Stock Price and Make-Whole Premium to the
Company and the Trustee within three Business Days of the request by the Company
or the Trustee. In addition, the Calculation Agent shall, on behalf of and upon
request by the Company or the Trustee, make the determinations described in
Section 6.1(d) above and deliver its calculations to the Company or the Trustee
by 9:00 p.m., New York City time, on the Business Day prior to the applicable
Fundamental Change Purchase Date. The Company or, at the Company's request, the
Trustee, in the name and at the expense of the Company, shall, on the date that
is the seventh Trading Day after the Effective Notice Date with respect to a
Fundamental Change in connection with which a Make-Whole Premium is payable,
mail to each Holder a notice in accordance with Section 16.2, and the Company
shall disseminate on such day a press release, setting forth the Stock Price and
Make-Whole Premium per $1,000 principal amount of Securities (including the
amount and kind of consideration per $1,000 principal amount in which such
Make-Whole Premium is payable) with respect to such Fundamental Change. Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice. The Company shall verify, in writing, to
the Trustee all calculations made by the Calculation Agent pursuant to this
Section 6.1(e). A Calculation Agent shall have the same rights as an Agent to
deal with the Company or an Affiliate of the Company. The Trustee shall not be
responsible for any of the aforementioned calculations and shall be entitled to
rely on an Officers' Certificate with respect to the same.

      (f) Prior to 10:00 a.m., New York City time, on each Fundamental Change
Purchase Date on which a Make-Whole Premium is payable, the Company shall
deposit with the Trustee or with one or more Paying Agents (or, if the Company
or an Affiliate or Subsidiary of the Company is acting as the Paying Agent, set
aside, segregate and hold in trust as provided in Section 2.4) an amount of
shares of Common Stock (or other consideration in which such Make-Whole Premium
is payable as herein provided), plus an amount in Cash for fractional interests
in accordance with Section 6.1(c), sufficient to pay the aggregate Make-Whole
Premium due on such Fundamental Change Purchase Date. Payment of the Make-Whole
Premium for Securities surrendered for conversion within the period described in
Section 6.1(a) shall be made promptly on the applicable Fundamental Change
Purchase Date by mailing checks in respect of Cash (or delivering such Cash by
wire transfer if permitted in accordance with Section 9.1) and otherwise
delivering entitlements to securities, other assets or property for the amount
payable to the Holders of such Securities entitled thereto as they shall appear
in the Register.

                                   ARTICLE 7

                                   CONVERSION

Section 7.1. Conversion Privilege.

      Subject to and upon compliance with the provisions of this Article 7 and
paragraph 8 of the Security, at the option of the Holder thereof, any Security,
in whole or in part, may be converted into fully paid and non-assessable Common
Stock at a Conversion Rate (the "Conversion Rate"), initially equivalent to
118.0638 shares of Common Stock per $1,000 principal amount of Securities,
subject to adjustment pursuant to Section 7.6, on or prior to the close of
business on the Final Maturity Date.

      The Securities shall be convertible only upon the occurrence of one of the
following events:

      (a) During any fiscal quarter, if the Closing Sale Price of the Common
Stock for at least twenty (20) Trading Days in the period of 30 consecutive
Trading Days ending on the last Trading Day of the preceding fiscal quarter
exceeds 130% of the Conversion Price per share of Common Stock on such


                                      -36-


last Trading Day. For each fiscal quarter, the Company shall determine whether
the Securities are convertible as the result of the satisfaction of this
condition in the preceding fiscal quarter and shall promptly notify the Trustee
accordingly. The Trustee shall, in turn, notify the Holders in each fiscal
quarter but in no event later than seven (7) Business Days after receiving
notification from the Company, as to the satisfaction of this condition.

      (b) For any Security called for redemption, during the period from the
date of any Redemption Notice pursuant to Section 3.3 to the close of business
on the Business Day immediately preceding the Redemption Date; provided, that if
a Holder has already delivered a Put Notice with respect to the Securities, such
Holder may not surrender its Securities for conversion until such notice has
been withdrawn in accordance with this Indenture.

      (c) During the five Trading Days after any five consecutive Trading Day
period in which the average of the Trading Prices for the Securities for such
five consecutive Trading Day period is less than 98% of the average of the
Conversion Values for the Securities during that period. The Trustee and the
Conversion Agent shall have no obligation to determine the applicability of this
condition, or to obtain secondary bid quotations with respect to any
determination of Trading Price except following the receipt of a Conversion
Notice indicating that the Holder's Securities are being converted based upon
the satisfaction of this Condition. Following receipt of such a Conversion
Notice, the Conversion Agent shall notify the Company which in turn shall select
the three independent nationally recognized securities dealers as described in
the definition of "Trading Price" from which the Conversion Agent shall receive
bid quotations. The Conversion Agent shall provide prompt notice to the Company
upon obtaining such bid quotations.

      (d) If the Company elects to distribute to all holders of Common Stock:

            (i) rights or warrants entitling them to subscribe for or purchase
      Common Stock at less than the Current Market Price on the Trading Day
      immediately preceding the declaration date for such distribution (other
      than a distribution of rights pursuant to the Existing Rights Plan); or

            (ii) Cash, debt securities or other evidence of indebtedness or
      other assets, which distribution, together with all other such
      distributions within the preceding twelve months, has a per share value
      exceeding 10% of the Current Market Price of the Common Stock as of the
      Trading Day immediately preceding the declaration date for such
      distribution,

The Company must notify the Holders at least 20 days prior to the ex-dividend
date for such distribution. Once the Company has given such notice, a Holder may
surrender its Securities for conversion at any time until the earlier of the
close of business on the Business Day prior to the ex-dividend date or the
Company's announcement that such distribution will not take place.

      (e) During the period beginning on the date of the Fundamental Change
Company Notice and until the second Trading Day preceding the Fundamental Change
Purchase Date, a Holder may surrender Securities for conversion and receive the
Fundamental Change Purchase Price and the Make Whole Premium due, if any, in
accordance with Article 6.

Section 7.2. Conversion Procedure

      (a) The right of conversion attaching to any Security may be exercised at
any time during which conversion is permitted in accordance with Section 7.1 (i)
if such Security is represented by a Global Secu-


                                      -37-


rity, by book-entry transfer to the Conversion Agent through the facilities of
the Depositary in accordance with the Applicable Procedures, or (ii) if such
Security is represented by a Certificated Security, by delivery of such Security
at the specified office of the Conversion Agent, accompanied, in either case,
by: (1) a duly signed and completed conversion notice, in the form as set forth
on the reverse of Security attached hereto as Exhibit A (a "Conversion Notice");
(2) if such Certificated Security has been lost, stolen, destroyed or mutilated,
a notice to the Conversion Agent in accordance with Section 2.7 regarding the
loss, theft, destruction or mutilation of the Security; (3) appropriate
endorsements and transfer documents if required by the Conversion Agent; and (4)
payment of any tax or duty, in accordance with Section 7.4, which may be payable
in respect of any transfer involving the issue or delivery of the Common Stock
in the name of a Person other than the Holder of the Security. The date on which
the Holder satisfies all of those requirements is the "Conversion Date." The
Company shall deliver to the Holder through a Conversion Agent Cash, if
applicable, and 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 7.3) on the applicable date specified for such delivery in the third
paragraph of Section 7.13(a) hereof.

      (b) The person in whose name the Security is registered shall be deemed to
be a stockholder of record on the Conversion Date; provided, however, that no
surrender of a Security or satisfaction of the other conditions in Section
7.2(b) 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, provided
that all such conditions have been satisfied, be effective to constitute the
person or persons entitled to receive such shares of Common Stock as the 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,
however, that such conversion shall be at the Conversion Rate in effect on the
date on which all such conditions have been satisfied and such Security was
delivered 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 separate payment or adjustment will be made for accrued and unpaid
interest on a converted Security or for dividends or distributions on shares of
Common Stock issued upon conversion of a Security except as provided in this
Indenture.

      (c) 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 of the unconverted portion of the
Security surrendered.

Section 7.3. Fractional Shares

      The Company will not issue fractional shares of Common Stock upon
conversion of Securities and instead will deliver Cash in an amount equal to the
value of such fraction computed on the basis of the Applicable Stock Price on
the Trading Day immediately before the Conversion Date.

Section 7.4. Taxes on Conversion

      If a Holder converts a Security, the Company shall pay any documentary,
stamp or similar issue or transfer taxes or duties relating to the issuance or
delivery of shares of Common Stock upon exercise of such conversion rights.
However, the Holder shall pay any tax or duty which may be payable relating to
any transfer involving the issuance or delivery of shares of Common Stock in a
name other than the Holder's name. The Conversion Agent may refuse to deliver
the certificate representing shares of 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 or duties 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.


                                      -38-


Section 7.5. Company to Provide Stock

      (a) The Company shall, prior to the issuance of any Securities hereunder,
and from time to time as may be necessary, reserve at all times and keep
available, free from preemptive rights, out of its authorized but unissued
Common Stock, a sufficient number of shares of Common Stock deliverable upon
conversion of all of the Securities.

      (b) All shares of Common Stock that may be issued upon conversion of the
Securities shall be newly issued shares or shares held in the treasury of the
Company, shall be duly authorized, validly issued, fully paid and nonassessable
and shall be free of any preemptive rights and free of any lien or adverse
claim.

      (c) The Company shall comply with all applicable securities laws
regulating the offer and delivery of any Common Stock upon conversion of
Securities and shall list or cause to have quoted such shares of Common Stock on
the NYSE or any United States national or regional securities exchange or on
Nasdaq or such other market on which the Common Stock is then listed or quoted;
provided, however, that, if the 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.

      (d) Notwithstanding anything herein to the contrary, nothing herein shall
give to any Holder any rights as a creditor in respect solely of its right to
conversion.

Section 7.6. Adjustment of Conversion Rate

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

      (a) In case the Company shall (i) issue shares of its Common Stock as a
dividend or distribution on its Common Stock or (ii) subdivide, combine or
reclassify its outstanding Common Stock, the Conversion Rate 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 been entitled to (without giving
effect to any arrangement pursuant to such dividend, distribution, subdivision,
combination or reclassification not to issue fractional shares of Common Stock)
had such Security been converted immediately prior to the record date of such
event or 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 a subdivision, combination or
reclassification.

      (b) In case the Company shall issue rights or warrants to all holders of
its Common Stock entitling them for a period of not more than 45 days to
subscribe for or purchase shares of Common Stock (or securities convertible into
Common Stock) at a price per share (or a conversion price per share) less than
the Current Market Price per share (as determined in accordance with subsection
(f) of this Section 7.6) of Common Stock on the record date for such issuance
(other than a distribution of rights pursuant to the Existing Rights Plan), the
Conversion Rate in effect immediately prior to the close of business on the
record date for the issuance shall be increased by multiplying the Conversion
Rate in effect immediately prior to the close of business on such record date by
a fraction of which (A) the numerator shall be the sum of (I) the number of
shares of Common Stock outstanding (excluding shares held in the treasury of the
Company) at the close of business on such record date and (II) the aggregate
number of shares (the "Underlying Shares") of Common Stock underlying all such
issued rights or warrants (whether by exer-


                                      -39-


cise, conversion, exchange or otherwise) and (B) the denominator shall be the
sum of (I) number of shares of Common Stock outstanding (excluding shares held
in the treasury of the Company) at the close of business on such record date and
(II) the number of shares of Common Stock which the aggregate exercise,
conversion, exchange or other price at which the Underlying Shares may be
subscribed for or purchased pursuant to such rights or warrants would purchase
at such Current Market Price per share of Common Stock. Such increase shall
become effective immediately prior to the opening of business on the Business
Day following such record date. In no event shall the Conversion Rate be
decreased pursuant to this Section 7.6(b). Notwithstanding the preceding
sentence, the Conversion Rate will be adjusted in accordance with this Section
7.6(b) to the extent that such rights or warrants are not exercised prior to
their expiration.

      (c) In case the Company shall distribute to all holders of its Common
Stock any shares of capital stock of the Company, evidences of indebtedness or
other non-Cash assets, or rights or warrants (excluding (i) dividends,
distributions and rights or warrants referred to in subsection (a) or (b) of
this Section 7.6, (ii) distributions referred to in subsection (e) of this
Section 7.6 and (iii) the distribution of rights pursuant to a shareholder
rights plan (including the Existing Rights Plan) for which provision has been
made in accordance with the third paragraph of this Section 7.6(c), the
Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the close of business on the record date for the
distribution by a fraction of which (A) the numerator shall be the Current
Market Price per share (as defined in subsection (f) of this Section 7.6)) of
the Common Stock on such record date and (B) the denominator shall be an amount
equal to (I) such Current Market Price per share less (II) 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 at the close of business on the record date); provided, however,
that, in the event the then fair market value (as so determined) 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 is equal to or greater than the Current Market Price per share of the
Common Stock on such record date, then, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Holder shall have the right to
receive upon conversion (in addition to any other consideration payable
hereunder upon conversion) the amount of capital stock, evidences of
indebtedness or other non-Cash assets so distributed or of such rights or
warrants such holder would have received had such holder converted each Security
on such record date. In no event shall the Conversion Rate be decreased pursuant
to this Section 7.6(c). Such adjustment (if any) shall be made successively
whenever any such distribution is made and shall become effective immediately
after such record date.

      In the event that such dividend or distribution is not so paid or made,
the Conversion Rate shall again be adjusted to be the Conversion Rate which
would then be in effect if such dividend or distribution had not been declared.
If the Board of Directors of the Company determines the fair market value of any
distribution for purposes of this Section 7.6(c) by reference to the actual or
when issued trading market for any securities, it must in doing so consider the
prices in such market over the same period used in computing the applicable
Current Market Price per share of Common Stock.

      The Company shall make adequate provisions such that, upon conversion of
the Securities into Common Stock, to the extent that the Existing Rights Plan or
any new shareholder rights plan (i.e. poison pill) hereafter implemented by the
Company is in effect upon such conversion, the Holders of Securities will
receive, in addition to the Common Stock and other consideration payable
hereunder upon conversion, the rights described in such Existing Rights Plan or
new rights plan (whether or not the rights have separated from the Common Stock
at the time of conversion), subject to the limitations set forth in such


                                      -40-


Existing Rights Plan or new rights plan. Any distribution of rights or warrants
pursuant to such Existing Rights Plan or new rights plan complying with the
requirements set forth in the immediately preceding sentence of this paragraph
shall not constitute a distribution of rights or warrants pursuant to this
Section 7.6(c).

      (d) In case the Company shall dividend or distribute (other than in
connection with a liquidation, dissolution or winding up of the Company) Cash in
excess of $0.01375 per share in any fiscal quarter, or $.0275 per share in any
fiscal quarter if the Company did not pay a dividend in the immediately
preceding quarter, (in each case as adjusted for stock dividends or
distributions or any subdivisions, combinations or reclassifications of our
outstanding common stock) (an "Excess Dividend") to all holders of Common Stock
(other than a distribution requiring an adjustment to the Conversion Rate
pursuant to Section 7.6(e)), the Conversion Rate shall be increased by
multiplying the Conversion Rate in effect immediately prior to the close of
business on the record date for the determination of holders of Common Stock
entitled to such dividend or distribution by a fraction (A) whose numerator
shall be the average of the Volume-Weighted Average Prices per share of Common
Stock (or, if such Volume-Weighted Average Prices are not available, the Closing
Sale Prices) for the five consecutive Trading Days ending on the date
immediately preceding the "ex" date (as defined in Section 7.6(f)) for such
Excess Dividend or distribution (which average shall be appropriately adjusted
by the Board of Directors, in its good faith determination (which determination
shall be described in a resolution of the Board of Directors), to account for
any adjustment, pursuant hereto, to the Conversion Rate that shall become
effective, or any event requiring, pursuant hereto, an adjustment to the
Conversion Rate where the "ex" date of such event occurs, at any time during
such five consecutive Trading Days); and (B) whose denominator shall be an
amount equal to (I) such average Volume-Weighted Average Price (or, if
applicable, average Closing Sale Price) per share of Common Stock less (II) the
amount per share of Common Stock of such Excess Dividend or distribution;
provided, however, that the Conversion Rate shall not be adjusted pursuant to
this Section 7.6(d) to the extent, and only to the extent, such adjustment would
cause the Conversion Price to be less than par value of the Common Stock (which
minimum amount shall be appropriately adjusted to reflect stock dividends on,
and subdivisions, combinations or reclassifications of, Common Stock); provided
further that, if the denominator of such fraction shall be equal to or less than
zero, the Conversion Rate shall be instead adjusted so that the Conversion Price
is equal to par value of the Common Stock (as adjusted in accordance with the
immediately preceding proviso). An adjustment to the Conversion Rate pursuant to
this Section 7.6(d) shall become effective immediately prior to the opening of
business on the Business Day immediately following such record date. In no event
shall the Conversion Rate be decreased pursuant to this Section 7.6(d).

      (e) In case the Company or any Subsidiary of the Company shall distribute
Cash or other consideration in respect of a tender offer or exchange offer made
by the Company or any Subsidiary of the Company for all or any portion of the
Common Stock where the sum of the aggregate amount of such Cash distributed and
the aggregate fair market value (as determined in good faith by the Board of
Directors, whose determination shall be conclusive and set forth in a resolution
of the Board of Directors), as of the Expiration Date (as defined below), of
such other consideration distributed (such sum, the "Aggregate Amount")
expressed as an amount per share of Common Stock validly tendered or exchanged,
and not withdrawn, pursuant to such tender offer or exchange offer as of the
Expiration Time (as defined below) (such tendered or exchanged shares of Common
Stock, the "Purchased Shares") exceeds the Current Market Price per share (as
determined in accordance with subsection (f) of this Section 7.6) of Common
Stock on the last date (such last date, the "Expiration Date") on which tenders
or exchanges could have been made pursuant to such tender offer or exchange
offer (as the same may be amended through the Expiration Date), then the
Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the close of business on the Expiration Date by a fraction
(A) whose numerator is equal to the sum of (I) the Aggregate Amount and (II) the
product of (a) the Current Market Price per


                                      -41-


share of Common Stock (as determined in accordance with subsection (f) of this
Section 7.6) on the Expiration Date and (b) an amount equal to the number of
shares of Common Stock outstanding as of the last time (the "Expiration Time")
at which tenders or exchanges could have been made pursuant to such tender offer
or exchange offer (excluding Purchased Shares and shares held at such time in
the treasury of the Company) and (B) whose denominator is equal to the product
of (I) the number of shares of Common Stock outstanding as of the Expiration
Time (including all Purchased Shares but excluding shares held at such time in
the treasury of the Company) and (II) such Current Market Price per share of
Common Stock on the Expiration Date. An increase, if any, to the Conversion Rate
pursuant to this Section 7.6(e) shall become effective immediately prior to the
opening of business on the Business Day following the Expiration Date. In the
event that the Company or a Subsidiary of the Company is obligated to purchase
shares of Common Stock pursuant to any such tender offer or exchange offer, but
the Company or such Subsidiary is permanently prevented by applicable law from
effecting any such purchases, or all such purchases are rescinded, then the
Conversion Rate shall again be adjusted to be the Conversion Rate which would
then be in effect if such tender offer or exchange offer had not been made. If
the application of this Section 7.6(e) to any tender offer or exchange offer
would result in a decrease in the Conversion Rate, no adjustment shall be made
for such tender offer or exchange offer under this Section 7.6(e).

      (f) For the purpose of making a computation pursuant to this Section 7.6,
the current market price (the "Current Market Price") on a date of determination
shall mean the average of the Closing Sale Prices per share of Common Stock for
the five consecutive Trading Days ending on the date of determination; provided,
however, that such Current Market Price shall be appropriately adjusted by the
Board of Directors, in its good faith determination (which determination shall
be described in a resolution of the Board of Directors), to account for any
adjustment pursuant hereto (other than the adjustment requiring such
computation) to the Conversion Rate that shall become effective, or any event
(other than the event requiring such computation) requiring, pursuant hereto, an
adjustment to the Conversion Rate where the "ex" date of such event occurs, at
any time during such five consecutive Trading Days. For purposes hereof, the
term "ex" date means (i) when used with respect to any dividend or distribution,
the first date on which the Common Stock trades, regular way, on the relevant
exchange or in the relevant market from which the Closing Sale Price was
obtained without the right to receive such dividend or distribution; and (ii)
when used with respect to any tender offer or exchange offer, the first date on
which the Common Stock trades, regular way, on the relevant exchange or in the
relevant market from which the Closing Sale Price was obtained after the
expiration time of such tender offer or exchange offer (as it may be amended or
extended).

      (g) In any case in which this Section 7.6 shall require that an adjustment
be made following a record date or Expiration Date, as the case may be,
established for purposes of this Section 7.6, the Company may elect to defer
(but only until five Business Days following the filing by the Company with the
Trustee of the certificate described in Section 7.9) issuing to the Holder of
any Security converted after such record date or Expiration Date the shares of
Common Stock and other capital stock of the Company, evidences of indebtedness
or other non-Cash assets or rights or warrants issuable upon such conversion
over and above the shares of Common Stock and other capital stock of the
Company, evidences of indebtedness or other non-Cash assets or rights or
warrants issuable, or Cash payable, upon such conversion only on the basis of
the Conversion Rate prior to adjustment; and, in lieu of the shares, evidences
of indebtedness or other non-Cash assets or rights or warrants the issuance of
which, or Cash the payment 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 or Cash, as the case
may be. If any distribution in respect of which an adjustment to the Conversion
Rate is required to be made as of the record date or Expiration Date therefor is
not thereafter made or paid by the Company for any reason, the Conversion Rate
shall be readjusted to the Conversion Rate which would then be in effect if such
record date had not been fixed or such effective date or Expiration Date had not
occurred.


                                      -42-


Section 7.7. No Adjustment

      No adjustment in the Conversion Rate shall be required unless the
adjustment would result in a change in the Conversion Rate of at least 1%;
provided, however, that any adjustment which by reason of this Section 7.7 is
not required to be made shall be carried forward and taken into account in
subsequent adjustments. All calculations under this Article 7 shall be made to
the nearest one-thousandth of a cent or to the nearest one-thousandth of a
share, as the case may be.

      Except as otherwise provided for in this Indenture, the Company shall not
be required to adjust the Conversion Rate for the issuance of its Common Stock
or any securities convertible or exchangeable for its Common Stock or the right
to purchase its Common Stock or such convertible or exchangeable securities.

      No adjustment need be made for (i) issuances of Common Stock pursuant to a
Company plan for reinvestment of dividends or interest or the investment or
additional optional amounts thereunder in shares of Common Stock or for a change
in the par value or a change to no par value of the Common Stock or (ii) upon
the issuance of any shares of Common Stock or options or rights to purchase
shares of Common Stock pursuant to any present or future employee, director or
consultant benefit plan or program of or assumed by the Company or any of its
subsidiaries.

      To the extent that the Securities become convertible into the right to
receive Cash, interest will not accrue on such Cash.

      No adjustment to the Conversion Rate need be made pursuant to Section 7.6
for a transaction if Holders are to participate in the transaction without
conversion on a basis and with notice that the Board of Directors of the Company
determines in good faith to be fair and appropriate in light of the basis and
notice on which holders of Common Stock participate in the transaction.

      No adjustment to the Conversion Rate need be made upon the issuance of any
shares of Common Stock pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security outstanding as of the date the Notes were
first issued.

      No adjustment to the Conversion Rate need be made for accrued and unpaid
interest, including additional interest, if any.

Section 7.8. Other Adjustments

      Subject to applicable stock exchange rules and listing standards, the
Company shall be entitled to increase the Conversion Rate by any amount for a
period of at least 20 days if the Company's Board of Directors determines that
such increase would be in the best interests in the Company, provided the
Company has given to holders at least 15 days' prior notice, in accordance with
Section 16.2, of any such increase in the Conversion Rate. Subject to applicable
stock exchange rules and listing standards, the Company shall be entitled to
increase the Conversion Rate, in addition to the events requiring an increase in
the Conversion Rate pursuant to Section 7.6, as it in its discretion shall
determine to be advisable in order to avoid or diminish any tax to stockholders
in connection with 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
stockholders.


                                      -43-


Section 7.9. Notice of Adjustment

      Whenever the Conversion Rate or conversion privilege is adjusted, the
Company shall promptly mail to Securityholders a notice of the adjustment in
accordance with Section 16.2, 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 Rate, the Trustee may assume without
inquiry that the Conversion Rate has not been adjusted and that the last
Conversion Rate of which it has knowledge remains in effect.

Section 7.10. [Reserved]

Section 7.11. Effect of Reclassification, Consolidation, Merger or Sale on
              Conversion Privilege

      If (1) there shall occur (a) any reclassification of the Company's Common
Stock (other than a change in par value, or from par value to no par value, or
from no par value to par value, or as a result of a subdivision or combination);
(b) a statutory share exchange, consolidation, merger or combination involving
the Company 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) a sale or conveyance as an entirety
or substantially as an entirety of the property and assets of the Company,
directly or indirectly, to another Person; and (2) pursuant to such
reclassification, statutory share exchange, consolidation, merger, combination,
sale or conveyance, holders of outstanding shares of Common Stock would be
entitled to receive stock (other than Common Stock), other securities, other
property, assets or Cash for such shares of Common Stock, then the Company, or
such successor or surviving, purchasing or transferee Person, as the case may
be, shall, as a condition precedent to such reclassification, statutory share
exchange, consolidation, merger, combination, sale or conveyance, execute and
deliver to the Trustee a supplemental indenture providing that, at and after the
effective time of such reclassification, statutory share exchange,
consolidation, merger, combination, sale or conveyance, 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, statutory share exchange,
consolidation, merger, combination, sale or conveyance by a holder of the number
of shares of Common Stock deliverable upon conversion of such Security
immediately prior to such reclassification, statutory share exchange,
consolidation, merger, combination, sale or conveyance, assuming that such
Holder would not have exercised any rights of election that such Holder would
have had as a holder of Common Stock to select a particular type of
consideration. Such supplemental indenture shall provide for adjustments of the
Conversion Rate which shall be as nearly equivalent as may be practicable to the
adjustments of the Conversion Rate provided for in this Article 7. If, in the
case of any such reclassification, statutory share exchange, 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 or surviving, purchasing or transferee Person, as the case may be,
in such reclassification, statutory share exchange, 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
of the Company shall reasonably consider necessary by reason of the foregoing.
The provisions of this Section 7.11 shall similarly apply to successive
reclassifications, statutory share exchanges, consolidations, mergers,
combinations, sales and conveyances. The foregoing, however, shall not in any
way affect the right a Holder of a Security may otherwise have pursuant to
Section 7.6(c) to receive rights and warrants in accordance therewith.


                                      -44-


      In the event the Company shall execute a supplemental indenture pursuant
to this Section 7.11, 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, statutory share exchange, consolidation, merger,
combination, sale or conveyance, any adjustment to be made with respect thereto
and that all conditions precedent have been satisfied and (y) an Opinion of
Counsel that all conditions precedent have been satisfied, and shall promptly
mail notice thereof to all Holders.

Section 7.12. Trustee's Disclaimer

      The Trustee shall have no duty to determine when an adjustment under this
Article 7 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 set forth in, 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 7.9.
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 7.

      The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 7.11, 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 7.11.

Section 7.13. Option to Satisfy Conversion Obligation with Cash, Common Stock or
              Combination Thereof

      (a) To satisfy the Company's obligation upon conversion of the Securities
(the "Conversion Obligation"), the Company may elect to deliver Cash or a
combination of Cash and shares of Common Stock in accordance with the provisions
of this Indenture. The Company shall notify the Holders through the Trustee of
the method the Company chooses to satisfy its Conversion Obligation as follows:
(i) in the Company's Notice of Redemption, if the Company has called the
Securities for redemption; (ii) no later than 21 Trading Days immediately
preceding the Final Maturity Date, in respect of Securities to be converted
during the period beginning 20 Trading Days immediately preceding the Final
Maturity Date and ending one Trading Day immediately preceding the Maturity
Date; and (iii) no later than two Trading Days immediately following the
Conversion Date in all other cases (such period, the "Settlement Notice
Period"). Except to the extent that the Company has irrevocably elected Net
Share Settlement upon conversion of the Securities pursuant to Section 7.13(b),
if the Company fails to give the notice described in the preceding sentence
within the prescribed time periods, then the Company shall satisfy its
Conversion Obligation only in shares of Common Stock (and Cash in lieu of
fractional shares). If the Company elects to satisfy any portion of its
Conversion Obligation in Cash, the Company shall specify in such notice the
amount to be satisfied in Cash as a percentage of the Conversion Obligation. The
Company shall treat all holders converting on the same Trading Day in the same
manner. The Company shall not have any obligation to satisfy its Conversion
Obligations arising on different Trading Days in the same manner.

      If the Company elects to satisfy any portion of the Conversion Obligation
in Cash (other than Cash in lieu of fractional shares), a Holder may retract its
Conversion Notice at any time during the two Trading Day period beginning on the
Trading Day after the date the Company gives notice to the Trustee of its chosen
method of settlement (the "Conversion Retraction Period"); provided, that no
such retraction can be made (and a holder's Conversion Notice shall be
irrevocable) (x) if the Company has irrevocably elected Net Share Settlement
pursuant to Section 7.13(b) before such Holder delivers its Conversion Notice,
(y) if the Holder is converting its Securities in connection with a redemption;
or (z) if the Holder de-


                                      -45-


livers the Conversion Notice during the period beginning 20 Trading Days
immediately preceding the Final Maturity Date and ending one Trading Day
immediately preceding the Final Maturity Date. No retraction can be made and a
holder's Conversion Notice shall be irrevocable if the Company does not elect to
deliver Cash in lieu of shares of Common Stock (other than Cash in lieu of
fractional shares).

      With respect to each Holder that exercises its conversion right in
accordance with this Indenture, if such Holder's Conversion Notice has not been
retracted as provided herein, assuming all of the other requirements for
conversion have been satisfied by such Holder, then settlement (a) in shares of
Common Stock only shall occur as soon as practicable after the Company notifies
the Trustee that settlement shall be in Common Stock only, and (b) in Cash or in
a combination of Cash and shares of Common Stock shall occur on the second
Trading Day following the final Trading Day of the Cash Settlement Averaging
Period.

      Settlement amounts will be computed as follows:

            (i) if the Company elects to satisfy the entire Conversion
      Obligation in Common Stock, the Company will deliver to such Holder a
      number of shares of Common Stock equal to (1) the aggregate principal
      amount of the Securities to be converted divided by 1,000 and multiplied
      by (2) the applicable Conversion Rate (plus Cash in lieu of any fractional
      shares);

            (ii) if the Company elects to satisfy the entire Conversion
      Obligation in Cash, the Company will deliver to such holder Cash in an
      amount equal to the product of:

                  (1) a number equal to (A) the aggregate principal amount of
            Securities to be converted divided by 1,000 and multiplied by (B)
            the applicable Conversion Rate; and

                  (2) the Applicable Stock Price.

            (iii) if the Company elects to satisfy the Conversion Obligation in
      a combination of Cash (excluding any Cash paid in lieu of any fractional
      shares) and Common Stock, the Company will deliver to such holder:

                  (1) Cash in an amount equal to the percentage of the
            Conversion Obligation to be paid in Cash specified in the notice
            regarding the Company's chosen method of settlement, multiplied by
            the amount of Cash that would be calculated pursuant to clause (ii)
            above in this paragraph; and

                  (2) a number of whole shares of Common Stock equal to (A) (x)
            the aggregate principal amount of Securities to be converted divided
            by 1,000 and multiplied by (y) the applicable Conversion Rate minus
            (B) the Cash amount determined pursuant to clause (1) of this
            sub-clause (iii) divided by the Applicable Stock Price.

      (b) Net Share Settlement. Notwithstanding anything to the contrary in the
Indenture, at any time on or prior to the 21st Trading Day preceding the Final
Maturity Date, the Company may irrevocably elect, in its sole discretion without
the consent of the Holders of the Securities, by written notice to the Trustee
and the Holders of the Securities, to satisfy in Cash its Conversion Obligation
with respect to the principal amount of Securities to be converted after the
date of such election, with any remaining amount to be satisfied in Cash, shares
of Common Stock or a combination of both. The settlement amount to be made
pursuant to this Section 7.13(b) shall be computed as follows:


                                      -46-


            (i) a Cash amount equal to lesser of (1) the aggregate principal
      amount of the Securities to be converted or (2) the product of (A) a
      number equal to (x) the aggregate principal amount of Securities to be
      converted divided by 1,000 and multiplied by (y) the applicable Conversion
      Rate and (B) the Applicable Stock Price; and

            (ii) (1) if the Company elects to satisfy any remaining amount in
      shares of Common Stock, the Company will deliver to the Holder a number of
      shares of Common Stock equal to (A) (x) the aggregate principal amount of
      Securities to be converted divided by 1,000 and multiplied by (y) the
      applicable Conversion Rate minus (B) the Cash amount determined pursuant
      to clause (i) above divided by the Applicable Stock Price, plus Cash in
      lieu of fractional shares;

                  (2) if the Company elects to satisfy any remaining amount in
            Cash, the Company will deliver to the Holder Cash in an amount equal
            to the product of:

                  (A) a number equal to (x) the aggregate principal amount of
            Securities to be converted divided by 1,000 and multiplied by (y)
            (I) the applicable Conversion Rate minus (II) $1,000 divided by the
            Applicable Stock Price; and

                  (B) the Applicable Stock Price; and

                  (3) if the Company elects to satisfy any remaining amount in a
            combination of Cash and shares of Common Stock, the Company will
            deliver to the Holder such combination in the respective amounts
            calculated in a manner comparable to that used to settle any
            conversion (as described above), and with the amount of Cash
            specified by the Company as contemplated in connection with any such
            conversion.

Section 7.14. Effect of Conversion; Conversion After Record Date

      Except as provided in this Section 7.14, a converting Holder of Securities
shall not be entitled to receive any separate Cash payments with respect to
accrued and unpaid interest on any such Securities being converted. By delivery
to the Holder of the number of shares of Common Stock or other consideration
issuable or Cash payable upon conversion in accordance with this Article 7, the
Company will have satisfied its obligations with respect to the Securities and
any accrued and unpaid interest on such Securities will not be paid. If any
Securities are converted after the close of business on an Interest Payment
Record Date but prior to the corresponding Interest Payment Date, the Holder of
such Securities as of the close of business on such Interest Payment Record Date
shall receive, on such Interest Payment Date, the interest payable on such
Security on such Interest Payment Date notwithstanding the conversion thereof;
provided, however, each Security surrendered for conversion after the close of
business on an Interest Payment Record Date but prior to the corresponding
Interest Payment Date shall be accompanied by payment from the converting Holder
thereof, for the account of the Company, in Cash, an amount equal to the
interest payable on such Security on such Interest Payment Date; provided
further that no such payment need be made (a) if the Company has specified a
Redemption Date that is after the close of business on an Interest Payment
Record Date but prior to the corresponding Interest Payment Date or that results
in conversion prior to that Interest Payment Date, (b) any overdue interest
exists at the time of conversion with respect to such Security, but only to the
extent of the amount of such overdue interest or (c) the Holder surrenders any
Securities for conversion after the close of business on the Interest Payment
Record Date relating to the final Interest Payment Date.

      Except as otherwise provided in this Indenture, no payment or adjustments
in respect of payments of interest on Securities surrendered for conversion or
any dividends or distributions on the Common Stock issued upon conversion shall
be made upon the conversion of any Securities.


                                      -47-


Section 7.15. Exchange in Lieu of Conversion

      (a) In lieu of it obligations pursuant to Section 7.2, the Company may, at
its option, direct the Conversion Agent to surrender, on or prior to the date of
determination of the Applicable Stock Price, Securities tendered for conversion
to a financial institution (the "Financial Institution") designated by the
Company for exchange in lieu of conversion. On the date of this Indenture, the
Company has designated Credit Suisse First Boston LLC as the Financial
Institution. If the Financial Institution accepts any such Securities
surrendered for conversion, it will deliver to the Conversion Agent, in exchange
for each $1,000 principal amount of such Securities, a number of shares of
Common Stock equal to the Applicable Conversion Rate (together with Cash for any
fractional shares), or Cash or a combination of Cash and shares of Common Stock
with a value equal to such shares of Common Stock. Any Cash amounts will be
based on the Applicable Stock Price.

      (b) If the Financial Institution accepts any such Securities, it will
deliver such shares of Common Stock, Cash or combination of Cash and Common
Stock, as the case may be, to the Conversion Agent and the Conversion Agent will
deliver such shares of Common Stock, Cash or combination of Cash and Common
Stock, as the case may be, to the Holder who has tendered such Securities for
conversion. If the Financial Institution agrees to accept any Securities for
exchange but does not timely deliver the related consideration, the Company
will, as promptly as practical thereafter, but not later than the third Business
Day following determination of the Applicable Stock Price, convert such
Securities into Cash and shares of Common Stock, if any, as provided in Section
7.2 above.

                                   ARTICLE 8

                              SUBSIDIARY GUARANTEE

Section 8.1. Subsidiary Guarantors

      If any Subsidiary of the Company shall guarantee any obligation of the
Company evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses by the Company (other than the Existing Credit Facility,
(each such obligation a "Debt Security") the Company shall (i) cause each of (1)
such Subsidiary and (2) any Subsidiary to which the Company has transferred all
or substantially all of its assets concurrently to become a Subsidiary Guarantor
by executing and delivering to the Trustee a supplemental indenture pursuant to
which such Subsidiary shall unconditionally guarantee (a "Subsidiary Guarantee")
all of the Company's obligations under the Securities and this Indenture on a
senior unsecured basis, on terms substantially consistent with guarantees of
substantially similar debt obligations, to the same extent as the Subsidiary
referred to above in (1) guaranteed such other Debt Securities and (ii) cause an
Opinion of Counsel to be delivered to the Trustee to the effect that such
supplemental indenture has been duly authorized and executed by each such Person
and constitutes the valid, binding and enforceable obligation of each such
Person (subject to customary exceptions concerning creditors' rights and
equitable principles).

      Such supplemental indenture shall be executed by manual signature on
behalf of each respective Subsidiary Guarantor by any one of such Subsidiary
Guarantor's Chairman of the Board of Directors, Vice Chairman of the Board of
Directors, Chief Executive Officer, President or Chief Financial Officer or Vice
Presidents, attested by its Secretary or Assistant Secretary.

      Such supplemental indenture bearing the manual signatures of individuals
who were at any time the proper officers of a Subsidiary Guarantor shall bind
such Subsidiary Guarantor, notwithstanding that


                                      -48-


such individuals or any of them have ceased to hold such offices prior to the
execution and delivery of the supplemental indenture or did not hold such
offices at the date of such supplemental indenture.

Section 8.2. Subsidiary Guarantors May Consolidate, Etc., on Certain Terms

      Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of any Subsidiary Guarantor with or into the
Company or any other Subsidiary Guarantor or shall prevent any sale or
conveyance of the property of any Subsidiary Guarantor as an entirety or
substantially as an entirety to the Company or any other Subsidiary Guarantor.

Section 8.3. Release of Subsidiary Guarantors

      If (i) subject to Article 10 hereof, any sale or other disposition of all
or substantially all of the assets of any Subsidiary Guarantor occurs (by way of
merger, consolidation or otherwise) or a sale or other disposition of all of the
Capital Stock of any Subsidiary Guarantor, in each case to a Person that is not
(either before or after giving effect to such transactions) the Company or a
Subsidiary of the Company, (ii) in the case of a Subsidiary referred to in
Section 8.1(i)(1) hereof, such Subsidiary is no longer a guarantor of any Debt
Securities, or (iii) in the case of a Subsidiary referred to in Section
8.1(i)(2) hereof, no Subsidiary of the Company is a guarantor of any Debt
Securities, and, in any such case, if the Company shall deliver to the Trustee
an Officers' Certificate certifying to that effect as of the date of such
Officers' Certificate, then automatically, without the requirement of any
further action by the Company, such Subsidiary or the Trustee, such Subsidiary
shall cease to be a Subsidiary Guarantor hereunder and such Subsidiary or, as
applicable in the case of clause (i) above, the acquiring Person shall have no
continuing obligation or liability under its Subsidiary Guarantee. The Trustee
shall, at the Company's expense, execute and deliver such instruments as the
Company may reasonably request to evidence such termination.

unless written notice thereof shall have been given to a Trust Officer at the
Corporate Trust Office of the Trustee by the Company (including, without
limitation, pursuant to Section 9.3), a Paying Agent, any Holder or any agent of
any Holder.

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 of plus
interest (including Additional Interest, if any) accrued and unpaid through the
date of such declaration on all the Securities then outstanding to be due and
payable upon any such declaration, and the same shall thereupon become and be
immediately due and payable.

      If an Event of Default with respect to the Company specified in clause (7)
or (8) of Section 11.1 occurs, all unpaid principal of plus accrued and unpaid
interest (including Additional Interest, if any) on all 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 or the Holders originally causing the acceleration by notice to
the Trustee may rescind an acceleration of Securities and its consequences
before a judgment or decree for the payment of money has been obtained by the
Trustee if (a) the rescission would not conflict with any existing order or
decree, (b) all existing Events of Default, other than the nonpayment of the
principal of plus accrued and unpaid interest on the Securities that has become
due solely by such declaration of acceleration, have been cured or waived and
(c) all payments due to the Trustee and any predecessor Trustee under Section
12.6 have been made. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

Section 11.3. 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 of or accrued and unpaid
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 11.4. Waiver of Defaults and Events of Default

      Subject to Sections 11.7 and 13.2, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by notice to the Trustee may
waive an existing Default or Event of Default and its consequence, except a
Default or Event of Default in the payment of the principal of, or any interest
(including Additional Interest, if any) on any Security, or the payment of any
applicable Fundamental


                                      -54-


Change Purchase Price or Redemption Price, or a failure by the Company to
convert any Securities in accordance with Article 7 or any Default or Event of
Default in respect of any provision of this Indenture or the Securities that,
under Section 13.2, cannot be modified or amended without the consent of the
Holders of each outstanding Security. When a Default or Event of Default is
waived, it is deemed cured, but no such waiver shall extend to any subsequent or
other Default or impair any consequent right. This Section 11.4 shall be in lieu
of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) is hereby
expressly excluded from this Indenture, as permitted by the TIA.

Section 11.5. Control by Majority

      The Holders of a majority in aggregate 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 under this Indenture. 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 security or indemnity reasonably satisfactory to it; provided
that the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction; provided further that this provision shall
not affect the rights of the Trustee set forth in Section 12.1(b)(v). This
Section 11.5 shall be in lieu of Section 316(a)(1)(A) of the TIA and such
Section 316(a)(1)(A) is hereby expressly excluded from this Indenture, as
permitted by the TIA.

Section 11.6. Limitations on Suits

      Subject to Section 11.7, a Holder of a Security may not pursue any remedy
with respect to this Indenture or the Securities unless:

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

                  (2) the Holders of at least 25% in aggregate principal amount
            of the then outstanding Securities make a written request to the
            Trustee to pursue the remedy;

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

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

                  (5) no direction inconsistent with such written request has
            been given to the Trustee during such 60-day period by the Holders
            of a majority in aggregate principal amount of the Securities then
            outstanding.

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

Section 11.7. Rights of Holders to Receive Payment and to Convert

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of the principal amount, Redemption
Price, Fundamental Change Purchase Price or interest (including Additional
Interest, if any) on any Security, on or after the respective due dates
expressed in the Security and this Indenture, to convert such Security in
accordance with Article 7 and to bring suit


                                      -55-


for the enforcement of any such payment on or after such respective dates or the
right to convert, is absolute and unconditional and shall not be impaired or
affected without the consent of the Holder.

Section 11.8. Collection Suit by Trustee

      If an Event of Default in the payment of principal or interest specified
in clause (1) or (2) of Section 11.1 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or another obligor on the Securities for the whole amount owing with
respect to the Securities and the amounts provided for in Section 12.6.

Section 11.9. Trustee May File Proofs of Claim

      The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and the Holders allowed in
any judicial proceedings relative to the Company (or any other obligor 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 12.6, 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 11.10. Priorities

      Any money or property collected by the Trustee pursuant to this Article
11, and after an Event of Default, any money or other property distributable in
respect of the Company's obligations under this Indenture shall be paid out in
the following order:

            First, to the Trustee (including any predecessor Trustee) for
      amounts due under Section 12.6;

            Second, to Securityholders for amounts due and unpaid on the
      Securities for the principal amount, Redemption Price, Fundamental Change
      Purchase Price or interest (including Additional Interest, if any) or
      Make-Whole Premium, if any, as the case may be, ratably, without
      preference or priority of any kind, according to such amounts due and
      payable on the Securities; and

            Third, the balance, if any, to the Company.

      The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 11.10. At least 15 days before such record
date, the Trustee shall mail to each Holder and the Company a notice that states
the record date, the payment date and the amount to be paid.


                                      -56-


Section 11.11. Undertaking for Costs

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 11.11 does not apply to a suit made by the Trustee, a
suit by a Holder pursuant to Section 11.7, or a suit by Holders of more than 25%
in aggregate principal amount of the Securities then outstanding. This Section
11.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is
hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 11.12. Delay or Omission Not Waiver

      No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article 11 or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

                                   ARTICLE 12

                                     TRUSTEE

Section 12.1. Certain Duties and Responsibilities of Trustee

      (a) The Trustee, prior to the occurrence of an Event of Default with
respect to the Securities and after the curing or waiving of all Events of
Default with respect to the Securities that may have occurred, shall undertake
to perform with respect to the Securities such duties and only such duties as
are specifically set forth in this Indenture, and no implied covenants shall be
read into this Indenture against the Trustee. In case an Event of Default with
respect to the Securities has occurred (that has not been cured or waived), the
Trustee shall exercise with respect to the Securities such of the rights and
powers vested in it by this Indenture, and use the same degree of care and skill
in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

      (b) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

            (i) prior to the occurrence of an Event of Default with respect to
      the Securities and after the curing or waiving of all such Events of
      Default with respect to the Securities that may have occurred:

                  (1) the duties and obligations of the Trustee shall with
            respect to the Securities be determined solely by the express
            provisions of this Indenture, and the Trustee shall not be liable
            with respect to the Securities except for the performance of such
            duties and obligations as are specifically set forth in this
            Indenture, and no implied covenants or obligations shall be read
            into this Indenture against the Trustee; and


                                      -57-


                  (2) in the absence of bad faith on the part of the Trustee,
            the Trustee may with respect to the Securities conclusively rely, as
            to the truth of the statements and the correctness of the opinions
            expressed therein, upon any certificates or opinions furnished to
            the Trustee and conforming to the requirements of this Indenture;
            but in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Trustee, the Trustee shall be under a duty to examine the same to
            determine whether or not they conform to the requirements of this
            Indenture (but need not confirm or investigate the accuracy of any
            mathematical calculations or other facts stated therein);

            (ii) This subsection shall not be construed to limit the effect of
      Section 12.1(b)(v).

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

            (iv) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the holders of not less than a majority in principal amount
      of the Securities at the time Outstanding (determined as provided in
      Section 2.8) relating to the time, method and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee under this Indenture with
      respect to the Securities; and

            (v) None of the provisions contained in this Indenture shall require
      the Trustee to expend or risk its own funds or otherwise incur personal
      financial liability in the performance of any of its duties or in the
      exercise of any of its rights or powers, if there is reasonable ground for
      believing that the repayment of such funds or liability is not reasonably
      assured to it under the terms of this Indenture or adequate indemnity
      against such risk is not reasonably assured to it.

      (c) Whether or not expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability or affording
protection to the Trustee shall be subject to the provisions of this Section.

Section 12.2. Certain Rights of Trustee

      Except as otherwise provided in Section 12.1:

      (a) The Trustee may conclusively rely and shall be fully protected in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
security or other paper or document (whether in original or facsimile form)
believed by it in good faith to be genuine and to have been signed or presented
by the proper party or parties;

      (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a resolution of the Company's Board of
Directors or an instrument signed in the name of the Company, by one or more
Officers thereof (unless other evidence in respect thereof is specifically
prescribed herein);

      (c) The Trustee may consult with counsel and the advice of such counsel or
any Opinion of Counsel shall be full and complete authorization and protection
in respect of any action taken or suffered or omitted hereunder in good faith
and in reliance thereon;


                                      -58-


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

      (e) The Trustee shall not be liable for any action taken or omitted to be
taken by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture;

      (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, but the Trustee, in its discretion, may make even
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.

      (g) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

      (h) The Trustee shall not be deemed to have knowledge or be charged with
knowledge of an Event of Default except (i) if the Trustee is acting as Paying
Agent, any Default or Event of Default occurring pursuant to Sections 9.1,
11.1(1) or 11.1(2) and (ii) any Default of Event of Default of which the Trustee
shall have received written notification which references the Securities and
this Indenture or obtained actual knowledge. Delivery of reports, information
and documents to the Trustee under Section 9.2 is for informational purposes
only and the Trustee's receipt of the foregoing shall not constitute
constructive notice of any information contained therein or determinable from
information contained therein, including the Company's compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely exclusively
on Officers' Certificates, except as otherwise provided herein);

      (i) The rights, privileges, protections, immunities and benefits given to
the Trustee pursuant hereto, 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 each agent, custodian and other person employed
by the Trustee to act hereunder;

      (j) The permissive right of the Trustee to take or refrain from taking any
actions enumerated in this Indenture shall not be construed as a duty;

      (k) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded;

      (l) Anything in this Indenture notwithstanding, in no event shall the
Trustee be liable for special, indirect, punitive or consequential loss or
damage of any kind whatsoever (including but not limited to loss of profit),
even if the Company has been advised as to the likelihood of such loss or damage
and regardless of the form of action; and


                                      -59-


      (m) The Trustee shall not be responsible or liable for any failure or
delay in the performance of its obligations under this Indenture arising out of
or caused, directly or indirectly, by circumstances beyond its reasonable
control, including, without limitation, acts of God; earthquakes; fire; flood;
terrorism; wars and other military disturbances; sabotage; epidemics; riots;
interruptions; loss or malfunctions of utilities, computer (hardware or
software) or communication services; accidents; labor disputes; acts of civil or
military authority and governmental action.

Section 12.3. Trustee Not Responsible for Recitals or Issuance or Securities

      (a) The recitals contained herein and in the Securities shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

      (b) The Trustee makes no representations as to the validity or sufficiency
of this Indenture or of the Securities.

      (c) The Trustee shall not be accountable for the use or application by the
Company of any of the Securities or of the proceeds of such Securities, or for
the use or application of any moneys paid over by the Trustee in accordance with
any provision of this Indenture or established pursuant to Section 2.1, or for
the use or application of any moneys received by any Paying Agent other than the
Trustee.

      (d) The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable for the Company's use of the Securities or the proceeds from the
Securities, it shall not be responsible for the correctness of any recital
contained, or for any statement of the Company, in this Indenture or any
document issued in connection with the sale of Securities or any statement in
the Securities other than the Trustee's certificate of authentication, or the
determination as to which beneficial owners are entitled to receive any notices
hereunder. The Trustee makes no representations with respect to the
effectiveness or adequacy of this Indenture or the Securities or any document
issued in connection with the sale of Securities.

Section 12.4. May Hold Securities

      The Trustee or any Paying Agent or Security Registrar, in its individual
or any other capacity, may become the owner or pledgee of Securities with the
same rights it would have if it were not Trustee, Paying Agent or Security
Registrar.

Section 12.5. Moneys Held in Trust

      Subject to the provisions of Section 11.5, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree with the Company to pay thereon.

Section 12.6. Compensation and Reimbursement

      (a) The Company covenants and agrees to pay to the Trustee, and the
Trustee shall be entitled to, such compensation (which shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust), as the Company and the Trustee may from time to time agree in writing
for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee, and, except as otherwise expressly provided herein, the Company
will pay or reimburse the Trustee upon its request for all reasonable ex-


                                      -60-


penses, disbursements and advances incurred or made by the Trustee in accordance
with any of the provisions of this Indenture (including the reasonable
compensation and the expenses and disbursements of its counsel and of all
Persons not regularly in its employ) except any such expense, disbursement or
advance as may arise from the Trustee's gross negligence, bad faith or willful
misconduct. The Company also covenants to indemnify the Trustee (and its
officers, agents, directors and employees) for, and to hold it harmless against,
any loss, liability or expense incurred without gross negligence or bad faith or
willful misconduct on the part of the Trustee and arising out of or in
connection with the acceptance or administration of this trust, including the
reasonable costs and expenses of defending itself against any claim of liability
in the premises. The obligations of the Company under this Section shall survive
the discharge of this Indenture and resignation or removal of the Trustee.

      (b) The obligations of the Company under this Section to compensate and
indemnify the Trustee and to pay or reimburse the Trustee for reasonable
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the Holders.

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 11.1(7) or (8) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

      For the purposes of this Section 12.6, the "Trustee" shall include any
predecessor Trustee; provided, however, that the gross negligence, bad faith or
willful misconduct of any Trustee hereunder shall not affect the rights of any
other Trustee hereunder.

Section 12.7. Reliance on Officers' Certificate

      Except as otherwise provided in Section 12.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting to take any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of bad faith on the part of the Trustee, be deemed to be conclusively
proved and established by an Officers' Certificate or Opinion of Counsel
delivered to the Trustee and such certificate, in the absence of bad faith on
the part of the Trustee, shall be full warrant to the Trustee for any action
taken, suffered or omitted to be taken by it under the provisions of this
Indenture upon the faith thereof.

Section 12.8. Disqualification; Conflicting Interests

      If the Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the TIA, the Trustee and the Company shall in all
respects comply with the provisions of Section 310(b) of the TIA.

Section 12.9. Corporate Trustee Required; Eligibility

      There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing
business under the laws of the United States of America or any State or
Territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the SEC, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus, or being
a member of a bank holding company with a combined capital and surplus, of at
least 50 million U.S. dollars ($50,000,000), and subject to supervision or
examination by Federal, State, Territorial or District of Columbia authority. If
such corporation publishes reports of con-


                                      -61-


dition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. The Company may not, nor may any Person directly or
indirectly controlling, controlled by, or under common control with the Company,
serve as Trustee. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect specified in Section 12.10.

Section 12.10. Resignation and Removal; Appointment of Successor

      (a) The Trustee or any successor hereafter appointed may at any time
resign as Trustee with respect to the Securities by giving written notice
thereof to the Company and by transmitting notice of resignation by mail, first
class postage prepaid, to the Securityholders, as their names and addresses
appear upon the Register. Upon receiving such notice of resignation, the Company
shall promptly appoint a successor trustee with respect to the Securities by or
pursuant to a resolution of the Board of Directors. If no successor trustee
shall have been so appointed and have accepted appointment within 30 days after
the mailing of such notice of resignation, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor trustee
with respect to the Securities, or any Securityholder who has been a bona fide
holder of a Security or Securities for at least six months may on behalf of
himself and all others similarly situated, petition any such court for the
appointment of a successor trustee. Such court may thereupon after such notice,
if any, as it may deem proper and prescribe, appoint a successor trustee.

      (b) In case at any time any one of the following shall occur:

            (i) the Trustee shall fail to comply with the provisions of Section
      12.8 after written request therefor by the Company or by any
      Securityholder who has been a bona fide holder of a Security or Securities
      for at least six months; or

                     5.25% CONVERTIBLE SENIOR NOTES DUE 2025

      This Security is one of a duly authorized issue of 5.25% Convertible
Senior Notes due 2025 (the "Securities") of the Company issued under an
Indenture, dated as of November 21, 2005 (the "Indenture"), between the Company
and The Bank of New York, as trustee (the "Trustee"). The terms of the Security
include those stated in the Indenture, those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (the "TIA"), and those
set forth in this Security. This Security is subject to all such terms, and
Holders are referred to the Indenture and the TIA for a statement of all such
terms. To the extent permitted by applicable law, if any provision of this
Security conflicts with the express provisions of the Indenture, the provisions
of the Indenture shall govern and be controlling. Capitalized terms used but not
defined herein have the meanings assigned to them in the Indenture unless
otherwise indicated.

1.    Interest.

      Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months as set forth on the face of the Security.

      If this Security is redeemed pursuant to paragraph 5 of this Security, or
the Holder elects to require the Company to purchase this Security pursuant to
paragraph 6 or 7 of this Security, on a date that is after an Interest Payment
Record Date but on or before the corresponding Interest Payment Date, interest
and Additional Interest, if any, accrued and unpaid hereon to, but not
including, the applicable Redemption Date or Fundamental Change Purchase Date
shall be paid to the same Holder to whom the Company pays the principal of this
Security. Interest and Additional Interest, if any, accrued and unpaid hereon at
the Final Maturity Date also shall be paid to the same Holder to whom the
Company pays the principal of this Security.

      Interest and Additional Interest, if any, on Securities converted after
the close of business on an Interest Payment Record Date but prior to the
corresponding Interest Payment Date shall be paid, on such Interest Payment
Date, to the Holder of the Securities as of the close of business on the
Interest Payment Record Date but, upon conversion, the converting Holder must
pay the Company an amount equal to the interest that shall be payable on such
Interest Payment Date. No such payment need be made with respect to Securities
converted after an Interest Payment Record Date and prior to the corresponding
Interest Payment Date (1) if the Company has specified a Redemption Date that is
after the close of business on an Interest Payment Record Date but prior to the
corresponding Interest Payment Date, (2) any overdue interest exists at the time
of conversion with respect to the Securities being converted, but only to the
extent of the amount of such overdue interest, or (3) if the Holder converts
after the close of business on the last Interest Payment Record date prior to
the Final Maturity Date.

      Except as otherwise stated herein, any reference herein to interest
accrued or payable as of any date shall include Additional Interest, if any,
accrued or payable on such date as provided in the Indenture or the Registration
Rights Agreement.

2.    Method of Payment.

      Payment of the principal of, and interest on, the Securities shall be made
at the office of the Paying Agent in such coin or currency of the United States
of America as at the time of payment is legal ten-


                                      -5-


der for payment of public and private debts. The Holder must surrender this
Security to a Paying Agent to collect payment of principal. Payment of interest
on Certificated Securities shall be made by check mailed to the address of the
Person entitled thereto as such address appears in the Register; provided,
however, that Holders with Securities in an aggregate principal amount in excess
of $2.0 million shall be paid, at their written election, by wire transfer of
immediately available funds. Notwithstanding the foregoing, so long as the
Securities are registered in the name of a Depositary or its nominee, all
payments with respect to the Securities shall be made by wire transfer of
immediately available funds to the account of the Depositary or its nominee.

3.    Paying Agent, Registrar, Conversion Agent.

      Initially, the Trustee will act as Paying Agent, Registrar and Conversion
Agent. The Company or any Affiliate of the Company may act as Paying Agent,
Registrar or Conversion Agent, subject to the terms of the Indenture.

4.    Indenture.

      The Securities are general unsubordinated unsecured obligations of the
Company limited to $75,000,000 aggregate principal amount. The Indenture does
not limit other debt of the Company, secured or unsecured.

5.    Redemption at the Option of the Company.

      At any time on and after November 1, 2010 and before November 1, 2012, the
Securities may be redeemed at the option of the Company in whole or in part as
described below, if in the previous 30 consecutive Trading Days ending on the
Trading Day before the date of the mailing of the Notice of Redemption the
Closing Sale Price of the Common Stock exceeds 130% of the Conversion Price for
at least 20 Trading Days. Upon any redemption pursuant to Section 3.1 of the
Indenture, the Company shall provide the notice required by Section 3.3 of the
Indenture (which notice may be revoked at any time prior to the time at which
the Company or the Trustee, as the case may be, has given such notice to
Securityholders) and shall pay a Redemption Price in Cash equal to 100% of the
principal amount of the Securities being redeemed, plus any accrued and unpaid
interest (including Additional Interest, if any) to, but excluding, the date
fixed for redemption, payable in Cash.

      At any time on and after November 1, 2012, the Securities may be redeemed
at any time or from time to time at the option of the Company in whole or in
part at the Redemption Price.

      A notice of redemption pursuant to this Section of this Security shall be
mailed at least 20 days but not more than 60 days before a Redemption Date to
each Holder of Securities to be redeemed at the Holder's address as such address
appears in the Register. If Cash sufficient to pay the Redemption Price of all
Securities for which notice of redemption is given is deposited with the Paying
Agent by 10:00 a.m., New York City time, on the Redemption Date, then, on and
after such Redemption Date, such Securities shall cease to be outstanding and
interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their Holders to the Paying Agent, and the Holders
thereof shall have no rights as such other than the right to receive the
Redemption Price upon delivery of such Securities to the Paying Agent.
Securities in denominations larger than $1,000 principal amount may be redeemed
in part but only in multiples of $1,000 principal amount.


                                      -6-


6.    Purchase by the Company Upon a Fundamental Change.

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase for Cash, at the option of any Holder, all or any
portion of the Securities held by such Holder upon a Fundamental Change in

right, a Holder shall deliver to the Paying Agent a Fundamental Change Purchase
Notice containing the information set forth in the Indenture, at any time prior

Agent as set forth in the Indenture.

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

      If Cash sufficient to pay the Fundamental Change Purchase Price of all
Securities or portions thereof to be purchased with respect to a Fundamental
Change Purchase Date is deposited with the Paying Agent by 10:00 a.m., New York
City time, on the Fundamental Change Purchase Date then, on and after such
Fundamental Change Purchase Date such Securities shall cease to be outstanding
and interest on such Securities shall cease to accrue, whether or not such
Securities are delivered by their Holders to the Paying Agent, and the Holders
thereof shall have no rights as such other than the right to receive the
Fundamental Change Purchase Price upon delivery of such Securities to the Paying
Agent.

7.    Purchase by the Company at the Option of the Holder on Specified Dates

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase for Cash, at the option of any Holder, all or any
portion of the Securities held by such Holder upon each Purchase Date in
multiples of $1,000 at the Put Option Purchase Price. To exercise such right, a
Holder shall deliver to the Paying Agent a Put Option Notice containing the
information set forth in the Indenture, at any time prior to 5:00 p.m., New York
City time, on the Business Day immediately preceding the Put Option Purchase
Date, and shall deliver the Securities to the Paying Agent as set forth in the
Indenture.

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

      If Cash sufficient to pay the Put Option Price of all Securities or
portions thereof to be purchased with respect to a Put Option Purchase Date is
deposited with the Paying Agent by 10:00 a.m., New York City time, on the Put
Option Purchase Date then, on and after such Put Option Purchase Date such
Securities shall cease to be outstanding and interest on such Securities shall
cease to accrue, whether or not such Securities are delivered by their Holders
to the Paying Agent, and the Holders thereof shall have no rights as such other
than the right to receive the Put Option Purchase Price upon delivery of such
Securities to the Paying Agent.

8.    Conversion.

      Subject to the terms of the Indenture, Holders may surrender Securities
for conversion into shares of Common Stock on or prior to the Final Maturity
Date at the Conversion Price then in effect if any of the following conditions
is satisfied:

      o     During any fiscal quarter, if the Closing Sale Price of the Common
            Stock for at least twenty (20) Trading Days in the period of 30
            consecutive Trading Days ending on the last Trading Day of the


                                      -7-


            preceding fiscal quarter exceeds 130% of the Conversion Price per
            share of Common Stock on such last Trading Day;

      o     If the Company has called the Securities for redemption;

      o     During the five Trading Days after any five consecutive Trading Day
            period in which the average of the Trading Prices for the Securities
            for such five consecutive Trading Day period is less than 98% of the
            average of the Conversion Values for the Securities during that
            period;

      o     If the Company proposes to make certain significant distributions to
            the Holders of the Company's Common Stock; or

      o     In connection with a Fundamental Change.

      Upon satisfaction of the any of the preceding conditions and subject to
the terms and conditions of the Indenture, a Holder of a Security may convert
the principal amount of such Security (or any portion thereof equal to $1,000
principal amount or any integral multiple of $1,000 principal amount in excess
thereof) into shares of Common Stock, or Cash or a combination of Cash and
shares of Common Stock if the Company shall so elect pursuant to Section 7.13 of
the Indenture, at any time prior to 5:00 p.m., New York City time, on the
Business Day immediately preceding the Final Maturity Date, at the Conversion
Rate then in effect; provided, however, that, if such Security is called for
redemption pursuant to paragraph 5, such conversion right shall terminate at the
close of business on the Business Day immediately preceding the Redemption Date,
unless there shall be a default in the payment of the Redemption Price, in which
case the conversion right with respect to such Security shall terminate at 5:00
p.m., New York City time, on the date such default is cured and such Security is
redeemed in accordance herewith; provided further, that, if a Put Notice with
respect to a Security is delivered in accordance with the Indenture, such
Security shall not be convertible unless such Put Notice is duly withdrawn in
accordance with the Indenture or unless there shall be a default in the payment
of the Put Price, in which case the conversion right with respect to such
Security shall terminate at 5:00 p.m., New York City time, on the date such
default is cured and such Security is purchased in accordance with the
Indenture.

      The initial Conversion Rate is 118.0638 shares of Common Stock per $1,000
principal amount of Securities, which represents an initial Conversion Price of
approximately $8.47 per share of Common Stock. The Conversion Rate is subject to
adjustment under certain circumstances as provided in the Indenture. No
fractional shares will be issued upon conversion. In lieu thereof, the Company
shall deliver Cash in an amount equal to the value of such fraction computed on
the basis of the Applicable Stock Price on the Trading Day immediately before
the Conversion Date.

      In lieu of issuing shares of Common Stock upon conversion of any
Securities, the Company in its discretion has the right to settle to its
Conversion Obligation in Cash or a combination of Cash and shares of Common
Stock as provided in Section 7.13 of the Indenture.

      To convert a Security, a Holder must (i) if the Security is represented by
a Global Security, comply with the Applicable Procedures, or (ii) if the
Security is represented by a Certificated Security, (a) deliver to the
Conversion Agent a duly signed and completed Conversion Notice set forth below,
(b) deliver the Security to the Conversion Agent, (c) deliver to the Conversion
Agent appropriate endorsements and transfer documents if required by the
Conversion Agent and (d) pay any tax or duty, if required pursuant to the
Indenture. A Holder may convert a portion of a Security equal to $1,000 or any
integral multiple thereof.

      The Company will furnish to any Holder, upon request and without charge,
copies of the certificate of incorporation and by-laws of the Company then in
effect. Any such request may be addressed to the Company or to the Registrar.


                                      -8-


9.    Make-Whole Premium.

      If a Fundamental Change occurs prior to November 1, 2012, the Company
shall pay the Make-Whole Premium to Holders of the Securities who convert their
Securities on a Conversion Date that falls within a period that (i) begins at
the opening of business on the date (the "Effective Notice Date") the
Fundamental Change Company Notice with respect to such Fundamental Change is
mailed in accordance with Section 5.1(b) of the Indenture and (ii) ends at the
close of business on the second Trading Day immediately preceding the
Fundamental Change Purchase Date corresponding to such Fundamental Change. The
Make-Whole Premium with respect to a Fundamental Change shall be paid solely in
shares of the Common Stock (other than Cash paid in lieu of fractional shares);
provided, however, that if, in connection with such Fundamental Change, all or
substantially all of the shares of Common Stock have been converted into or
exchanged for Cash, other securities or other property, then such Make-Whole
Premium shall be paid in the same form of consideration into which all or
substantially all of the shares of Common Stock have been converted or exchanged
in connection with such Fundamental Change (other than Cash paid in lieu of
fractional interests in any security or pursuant to dissenters' rights), in
accordance with the Indenture. The value of the Make-Whole Premium shall be
equal to an applicable percentage of the principal amount of the Securities
specified in the Indenture. The Make-Whole Premium will be in addition to, and
not in substitution for, any Cash, securities or other assets otherwise due to
Holders of Securities upon conversion as described in the Indenture.

10.   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
of or exchange Securities in accordance with the Indenture. The Registrar may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay certain taxes, assessments or other governmental
charges that may be imposed in relation thereto by law or permitted by the
Indenture.

11.   Persons Deemed Owners.

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

      The Trustee and the Paying Agent shall return to the Company upon written
request any Cash or securities held by them for the payment of any amount with
respect to the Securities that remains unclaimed for two years, subject to

creditors unless an applicable abandoned property law designates another person.

13.   Amendment, Supplement and Waiver.

      Subject to certain exceptions, the Securities or the Indenture may be
amended or supplemented with the consent of the Holders of at least a majority
in aggregate principal amount of the Securities then outstanding, and, subject
to certain exceptions, an existing Default or Event of Default with respect to
