receive the interest payable on such interest payment date, except that the interest payable upon
maturity, redemption or repurchase following a Fundamental Change will be payable to the Person to
whom principal is payable upon maturity or pursuant to such redemption or repurchase following a
Fundamental Change (unless the redemption date or the Fundamental Change Repurchase Date, as the
case may be, is after a Record Date and on or prior to the corresponding interest payment date, in
which case the semi-annual payment of interest becoming due on such interest payment date shall be
payable to the Holder of such Debentures registered as such on the applicable Record Date).
Notwithstanding the foregoing, any Debentures or portion thereof surrendered for conversion during
the period from 5:00 p.m., New York City time, on the Record Date for any interest payment date to
5:00 p.m., New York City time, on the Business Day preceding the applicable interest payment date
shall be accompanied by payment, in immediately available funds or other funds acceptable to the
Company, of an amount equal to the interest otherwise payable on such interest payment date on the
principal amount being converted; provided that no such payment need be made (1) if a
Holder converts its Debentures in connection with a redemption and the Company has specified a
redemption date that is after a Record Date and on or prior to the next interest payment date, (2)
if a Holder converts its Debentures in connection with a Fundamental Change and the Company has
specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the

of conversion with respect to such Debentures.

          The Company shall pay interest (i) on any Global Debentures by wire transfer of immediately
available funds to the account of the Depositary or its nominee, (ii) on any Debentures in
certificated form having a principal amount of less than $2,000,000, by check mailed to the address

- 20 -

 

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

          The Trustee shall authenticate and make available for delivery Debentures in the form set
forth in Exhibit A.

          The Trustee may appoint an authenticating agent reasonably acceptable to the Company to
authenticate the Debentures. Any such appointment shall be evidenced by an instrument signed by a
Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Debentures whenever the Trustee
may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying
Agent or agent for service of notices and demands.

          SECTION 2.05.   Registrar and Paying Agent. The Company shall maintain an office or
agency where Debentures may be presented for registration of transfer or for exchange (the
“Registrar”) and an office or agency where Debentures may be presented for payment (the “Paying
Agent”). The Corporate Trust Office shall be considered as one such office or agency of the
Company for each of the aforesaid purposes. The Registrar shall keep a register of the Debentures
(the “Register”) and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term “Paying Agent” includes any
additional paying agent, and the term “Registrar” includes any co-registrars. The Company
initially appoints the Trustee as (i) Registrar and Paying Agent in connection with the Debentures,
(ii) the custodian with respect to the Global Debentures and (iii) conversion agent.

          The Company shall enter into an appropriate agency agreement with any Registrar or Paying
Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement
shall implement the provisions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company fails to maintain a
Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate
compensation therefor pursuant to Section 7.07. The Company or any of its domestically organized
Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

          The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or
Paying Agent and to the Trustee; provided, however, that no such removal shall
become effective until (1) acceptance of an appointment by a successor as evidenced by an
appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as
the case may be, and delivered to the Trustee or (2) notification to the Trustee that the Trustee
shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with
clause (1) above. The Registrar or Paying Agent may resign at any time upon written notice;
provided, however, that the Trustee may resign as Paying Agent or Registrar only if
the Trustee also resigns as Trustee in accordance with Section 7.08.

          SECTION 2.06.   Paying Agent to Hold Money in Trust. Prior to each due date of the
principal and interest on any Debenture, the Company shall deposit with the Paying Agent (or if the
Company or a Subsidiary is acting as Paying Agent, segregate and hold in trust for the

- 21 -

 

benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest
when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to
agree in writing that the Paying Agent shall hold in trust for the benefit of Debentureholders or
the Trustee all money held by the Paying Agent for the payment of principal of or interest on the
Debentures and shall notify the Trustee of any default by the Company in making any such payment.
If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account for any funds
disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no
further liability for the money delivered to the Trustee.

          SECTION 2.07.   Debentureholder 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 Debentureholders. If the Trustee is not the Registrar, the Company shall furnish, or cause the
Registrar to furnish, to the Trustee, in writing at least five Business Days before each interest
payment date and at such other times as the Trustee may request in writing, a list in such form and
as of such date as the Trustee may reasonably require of the names and addresses of
Debentureholders.

          SECTION 2.08.   Exchange and Registration of Transfer of Debentures. (a) The Company
shall cause to be kept at the Corporate Trust Office the Register in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the registration of
Debentures and of transfers of Debentures. The Register shall be in written form or in any form
capable of being converted into written form within a reasonably prompt period of time.

          Upon surrender for registration of transfer of any Debentures to the Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section
2.08, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Debentures of any authorized denominations
and of a like aggregate principal amount and bearing such restrictive legends as may be required by
this Indenture.

          Debentures may be exchanged for other Debentures of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Debentures to be exchanged at any such office or
agency maintained by the Company pursuant to Section 4.02. Whenever any Debentures are so
surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Debentures that the Holder making the exchange is entitled to receive bearing
registration numbers not contemporaneously outstanding.

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

          All Debentures presented or surrendered for registration of transfer or for exchange,
redemption, repurchase or conversion shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument or instruments of

- 22 -

 

transfer in form satisfactory to the Company, and the Debentures shall be duly executed by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to any Holder for any registration of, transfer or exchange of
Debentures, but the Company or the Trustee may require payment by the Holder of a sum sufficient to
cover any tax, assessment or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Debentures.

          Neither the Company nor the Trustee nor any Registrar shall be required to exchange, issue or
register a transfer of (a) any Debentures for a period of fifteen calendar days next preceding date
of mailing of a notice of redemption, (b) any Debentures or portions thereof called for redemption
pursuant to Section 3.02, except for the unredeemed portion of any Debentures being redeemed in
part, (c) any Debentures or portions thereof surrendered for conversion pursuant to Article 10 or
(d) any Debentures or portions thereof tendered for repurchase (and not withdrawn) pursuant to
Section 3.04.

          (b) The following provisions shall apply only to Global Debentures:

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

     (ii) Notwithstanding any other provision in this Indenture, no Global
Debentures may be exchanged in whole or in part for Debentures registered, and no
transfer of a Global Debenture in whole or in part may be registered, in the name of
any Person other than the Depositary or a nominee thereof unless (A) the Depositary
(x) has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Debenture or (y) has ceased to be a clearing agency
registered under the Exchange Act, and a successor depositary has not been appointed
by the Company within 90 calendar days, or (B) the Company, in its sole discretion,
notifies the Trustee in writing that it no longer wishes to have all the Debentures
represented by Global Debentures. Any Global Debentures exchanged pursuant to this
Section 2.08(b)(ii) shall be so exchanged in whole and not in part.

     (iii) In addition, certificated Debentures will be issued in exchange for
beneficial interests in a Global Debenture upon request by or on behalf of the
Depositary in accordance with customary procedures following the request of a
beneficial owner seeking to enforce its rights under the Debentures or this
Indenture, including its rights following the occurrence of an Event of Default.

     (iv) Debentures issued in exchange for a Global Debenture or any portion
thereof pursuant to clause (ii) or (iii) above shall be issued in definitive, fully
registered form, without interest coupons, shall have an aggregate principal amount
equal to that of such Global Debentures or portion thereof to be so

- 23 -

 

exchanged, shall be registered in such names and be in such authorized
denominations as the Depositary shall designate and shall bear any legends required
hereunder. Any Global Debentures to be exchanged shall be surrendered by the
Depositary to the Trustee, as Registrar, provided that pending completion of
the exchange of a Global Debenture, the Trustee acting as custodian for the Global
Debentures for the Depositary or its nominee with respect to such Global Debentures,
shall reduce the principal amount thereof, by an amount equal to the portion thereof
to be so exchanged, by means of an appropriate adjustment made on the records of the
Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and
make available for delivery the Debentures issuable on such exchange to or upon the
written order of the Depositary or an authorized representative thereof.

     (v) In the event of the occurrence of any of the events specified in clause
(ii) above or upon any request described in clause (iii) above, the Company will
promptly make available to the Trustee a sufficient supply of certificated
Debentures in definitive, fully registered form, without interest coupons.

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

     (vii) At such time as all interests in a Global Debenture have been redeemed,
repurchased, converted, cancelled or exchanged for Debentures in certificated form,
such Global Debenture shall, upon receipt thereof, be canceled by the Trustee in
accordance with standing procedures and instructions existing between the Depositary
and the custodian for the Global Debenture. At any time prior to such cancellation,
if any interest in a Global Debenture is redeemed, repurchased, converted, cancelled
or exchanged for Debentures in certificated form, the principal amount of such
Global Debenture shall, in accordance with the standing procedures and instructions
existing between the Depositary and the custodian for the Global Debenture, be
appropriately reduced, and an endorsement shall be made on such Global Debenture, by
the Trustee or the custodian for the Global Debenture, at the direction of the
Trustee, to reflect such reduction.

- 24 -

 

          (c) The Trustee shall have no responsibility or obligation to any Agent Members or any other
Person with respect to the accuracy of the books or records, or the acts or omissions, of the
Depositary or its nominee or of any participant or member thereof, with respect to any ownership
interest in the Debentures or with respect to the delivery to any Agent Member or other Person
(other than the Depositary) of any notice (including any notice of redemption) or the payment of
any amount, under or with respect to such Debentures. All notices and communications to be given
to the Holders of Debentures and all payments to be made to Holders of Debentures under the
Debentures shall be given or made only to or upon the order of the registered Holders of Debentures
(which shall be the Depositary or its nominee in the case of a Global Debenture). The rights of
beneficial owners in any Global Debentures shall be exercised only through the Depositary subject
to the customary procedures of the Depositary. The Trustee may rely and shall be fully protected
in relying upon information furnished by the Depositary with respect to its Agent Members.

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

          SECTION 2.09.   Replacement Debentures. If a mutilated Debenture is surrendered to
the Registrar or if the Debentureholder of a Debenture claims that the Debenture has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Debenture if the requirements of Section 8-405 of the Uniform Commercial Code are met,
such that the Debentureholder (i) satisfies the Company or the Trustee within a reasonable time
after he has notice of such loss, destruction or wrongful taking and the Registrar does not
register a transfer prior to receiving such notification, (ii) makes such request to the Company or
the Trustee prior to the Debenture being acquired by a protected purchaser as defined in Section
8-303 of the Uniform Commercial Code (a “protected purchaser”) and (iii) satisfies any other
reasonable requirements of the Trustee. If required by the Trustee or the Company, such Debentureholder shall furnish an indemnity bond sufficient in
the judgment of the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar
from any loss that any of them may suffer if a Debenture is replaced. The Company and the Trustee
may charge the Debentureholder for their expenses in replacing a Debenture. In case any Debentures
which have matured or are about to mature or have been called for redemption or have been properly
tendered for repurchase on a Fundamental Change Repurchase Date (and not withdrawn), as the case
may be, or are to be converted into Common Stock, shall become mutilated or be destroyed, lost or
stolen, the Company may, instead of issuing substitute Debentures, pay or authorize the payment of
or convert or authorize the conversion of the same (without surrender thereof except in the case of
a mutilated Debentures), as the case may be, if the applicant for such payment or conversion shall
furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such
security or indemnity as may be required by them to save each of them harmless for any loss,
liability, cost or expense caused by or in connection with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if
applicable, any Paying Agent or conversion agent

- 25 -

 

evidence to their satisfaction of the destruction,
loss or theft of such Debentures and of the ownership thereof.

          Every replacement Debenture is an additional obligation of the Company.

          The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Debentures.

          SECTION 2.10.   Outstanding Debentures. Debentures outstanding at any time are all
Debentures authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section as not outstanding. A Debenture does not cease to
be outstanding because the Company or an Affiliate of the Company holds the Debenture.

          If a Debenture is replaced pursuant to Section 2.09, it ceases to be outstanding unless the
Trustee and the Company receive proof satisfactory to them that the replaced Debenture is held by a
protected purchaser.

          If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a
redemption date, repurchase date or Maturity Date money sufficient to pay all principal and
interest payable on that date with respect to the Debentures (or portions thereof) to be redeemed,
repurchased or maturing, as the case may be, and the Paying Agent is not prohibited from paying
such money to the Debentureholders on that date pursuant to the terms of this Indenture, then on
and after that date such Debentures (or portions thereof) cease to be outstanding and interest on
them ceases to accrue.

          SECTION 2.11.   Temporary Debentures. Pending the preparation of Debentures in
certificated form, the Company may execute and the Trustee or an authenticating agent appointed by
the Trustee shall, upon the written request of the Company, authenticate and deliver temporary
Debentures (printed or lithographed). Temporary Debentures shall be issuable in any authorized
denomination, and substantially in the form of the Debentures in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary
Debentures, all as may be determined by the Company. Every such temporary Debentures shall be
executed by the Company and authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as the Debentures in
certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee
or such authenticating agent Debentures in certificated form and thereupon any or all temporary
Debentures may be surrendered in exchange therefor, at each office or agency maintained by the
Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate
and make available for delivery in exchange for such temporary Debentures an equal aggregate
principal amount of Debentures in certificated form. Such exchange shall be made by the Company at
its own expense and without any charge therefor. Until so exchanged, the temporary Debentures
shall in all respects be entitled to the same benefits and subject to the same limitations under
this Indenture as Debentures in certificated form authenticated and delivered hereunder.

- 26 -

 

          SECTION 2.12.   Cancellation. The Company at any time may deliver Debentures to the
Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Debentures surrendered to them for registration of transfer, exchange or payment. The Trustee and
no one else shall cancel all Debentures surrendered for registration of transfer, exchange, payment
or cancellation and dispose of such canceled Debentures in accordance with its customary procedures
or deliver canceled Debentures to the Company. The Company may not issue new Debentures to replace
Debentures it has redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall
not authenticate Debentures in place of canceled Debentures other than pursuant to the terms of
this Indenture.

          SECTION 2.13.   Defaulted Interest. If the Company defaults in a payment of interest
on the Debentures, the Company shall pay the defaulted interest (plus interest on such defaulted
interest at the rate of 1% per annum above the then applicable interest rate on the Debentures to
the extent lawful) in any lawful manner not inconsistent with the requirements of the New York
Stock Exchange or any other national securities exchange or automated quotation system on which
such Debentures are listed or quoted. The Company may pay the defaulted interest to the Persons
who are Debentureholders on a subsequent special record date. The Company shall fix or cause to be
fixed any such special record date and payment date to the reasonable satisfaction of the Trustee
and shall promptly mail or cause to be mailed to each Debentureholder a notice that states the
special record date, the payment date and the amount of defaulted interest to be paid.

          SECTION 2.14.   CUSIP and ISIN Numbers. The Company in issuing the Debentures may use
“CUSIP” and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” and
“ISIN” numbers in notices of redemption as a convenience to Debentureholders; 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 Debentures or as contained in any notice of a
redemption and that reliance may be placed only on the other identification numbers printed on the
Debentures, and any such redemption shall not be affected by any defect in or omission of such
numbers. The Company shall promptly notify the Trustee in writing of any changes to the CUSIP and
ISIN numbers.

ARTICLE 3

Redemption and Repurchase of Debentures

          SECTION 3.01.   Optional Redemption of Debentures. (a) At any time on or after
September 15, 2016, the Debentures may be redeemed at the option of the Company, in whole or in
part, upon notice as set forth in Section 3.02, in cash at the redemption price equal to 100% of
the principal amount thereof. In addition, the Company will pay interest on the Debentures being
redeemed, which interest will include such interest accrued and unpaid to, but excluding, the
redemption date; provided, that if the redemption date is after a Record Date and on or
prior to the corresponding interest payment date, the interest will be paid on the redemption date
to the Holder of record on the Record Date.

          (b) At any time on or prior to September 15, 2010, if a Tax Triggering Event has occurred, the
Debentures may be redeemed at the option of the Company, in whole or in part,

- 27 -

 

upon notice as set forth in Section 3.02, in cash at the redemption price equal to 101.5% of the principal amount
thereof plus if the Conversion Value as of the redemption date of the Debentures being redeemed
exceeds their Initial Conversion Value, 95% of the amount determined by subtracting the Initial
Conversion Value of such Debentures from their Conversion Value as of the redemption date. In
addition, the Company will pay interest on the Debentures being redeemed, which interest will
include such interest accrued and unpaid to, but excluding, the redemption date; provided,
that if the redemption date is after a Record Date and on or prior to the corresponding interest
payment date, the interest will be paid on the redemption date to the Holder of record on the
Record Date.

          (c) Notwithstanding the foregoing, the Company may not redeem any Debentures pursuant to
Section 3.01(a) or (b) if a Default in the payment of interest on the Debentures has occurred and
is continuing.

          SECTION 3.02.   Notice of Optional Redemption; Selection of Debentures to Be Redeemed.
In case the Company shall desire to exercise the right to redeem all or, as the case may be, any
part of the Debentures pursuant to Section 3.01, it shall fix a date for redemption and it or, at
its written request received by the Trustee not fewer than five Business Days prior (or such
shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is
to be mailed, the Trustee in the name of and at the expense of the Company, shall mail or cause to
be mailed a notice of such redemption not fewer than 30 calendar days nor more than 60 calendar
days prior to the redemption date to each Holder of Debentures so to be redeemed in whole or in
part at its last address as the same appears on the Register; provided that such notice
must be given at least 24 Scheduled Trading Days prior to the redemption date; provided,
further that if the Company makes such request of the Trustee, it shall, together with such
request, also give written notice of the redemption date to the Trustee, provided that the
text of the notice shall be prepared by the Company. Such mailing shall be by first class mail.
The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been
duly given, whether or not the Holder receives such notice. In any case, failure to give such
notice by mail or any defect in the notice to the Holder of any Debentures designated for
redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Debentures. Concurrently with the mailing of any such notice of
redemption, the Company shall issue a press release announcing such redemption, the form and
content of which press release shall be determined by the Company in its sole discretion. The
failure to issue any such press release or any defect therein shall not affect the validity of the
redemption notice or any of the proceedings for the redemption of any Debentures called for
redemption.

          Each such notice of redemption shall specify: (i) the aggregate principal amount of Debentures
to be redeemed, (ii) the CUSIP number or numbers of the Debentures being redeemed, (iii) the date
fixed for redemption (which shall be a Business Day), (iv) the redemption price at which Debentures
are to be redeemed, (v) the place or places of payment and that payment will be made upon
presentation and surrender of such Debentures, (iv) that interest accrued and unpaid to, but
excluding, the date fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon or on the portion thereof to be redeemed will cease to accrue,
(vii) that the Holder has a right to convert the Debentures called for redemption, (viii) the
Conversion Rate on the date of such notice, (ix) the time and date on

- 28 -

 

which the right to convert
such Debentures or portions thereof will expire, (x) the formula for determining the amount of cash
and the number of shares, if any, to be delivered to the Holder upon conversion pursuant to Section
10.12 and the date on which the Cash Settlement Averaging Period begins and (xi) that the Company
will pay cash for fractional interests in shares of Common Stock, if any, as provided in this
Indenture. If fewer than all the Debentures are to be redeemed, the notice of redemption shall
identify the Debentures to be redeemed (including CUSIP numbers, if any). In case any Debentures
are to be redeemed in part only, the notice of redemption shall state the portion of the principal
amount thereof to be redeemed and shall state that, on and after the redemption date, upon
surrender of such Debentures, a new Debentures or Debentures in principal amount equal to the
unredeemed portion thereof will be issued.

          Whenever any Debentures are to be redeemed, the Company will give the Trustee written notice
of the redemption date, together with an Officers’ Certificate as to the aggregate principal amount
of Debentures to be redeemed not fewer than 35 calendar days (or such shorter period of time as may
be acceptable to the Trustee) prior to the redemption date.

          On or prior to the redemption date specified in the notice of redemption given as provided in
this Section 3.02, the Company will deposit with the Paying Agent (or, if the Company is acting as
its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.06) an amount
of money in immediately available funds sufficient to redeem on the redemption date all the
Debentures (or portions thereof) so called for redemption (other than those theretofore surrendered
for conversion into Common Stock) at the appropriate redemption price, together with accrued and
unpaid interest to, but excluding, the redemption date; provided that if such payment is
made on the redemption date, it must be received by the Paying Agent, by 11:00 a.m., New York City
time, on such date. If any Debentures called for redemption are converted pursuant hereto prior to
such redemption date, any money deposited with the Paying Agent or so segregated and held in trust
for the redemption of such Debentures shall be paid to the Company or, if then held by the Company,
shall be discharged from such trust.

          If less than all of the outstanding Debentures are to be redeemed, the Trustee shall select
the Debentures or portions thereof of the Global Debentures or the Debentures in certificated form to be redeemed (in principal amounts of $1,000 or integral multiples
thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate
and not inconsistent with the requirements of the New York Stock Exchange or any other national
securities exchange or automated quotation system on which such Debentures are then listed or
quoted. If any Debentures selected for redemption are submitted for conversion in part after such
selection, the portion of such Debentures submitted for conversion shall be deemed (so far as may
be possible) to be the portion to be selected for redemption. The Debentures (or portions thereof)
so selected for redemption shall be deemed duly selected for redemption for all purposes hereof,
notwithstanding that any such Debentures are submitted for conversion in part before the mailing of
the notice of redemption.

          Upon any redemption of less than all of the outstanding Debentures, the Company and the
Trustee may (but need not), solely for purposes of determining the pro rata allocation among such
Debentures that are unconverted and outstanding at the time of redemption, treat as outstanding any
Debentures surrendered for conversion during the period of fifteen calendar days preceding the
mailing of a notice of redemption and may (but need not) treat as outstanding any

- 29 -

 

Debentures authenticated and delivered during such period in exchange for the unconverted portion of any
Debentures converted in part during such period.

          If at any time and for so long as any Debentures shall be listed on the New York Stock
Exchange or any other national securities exchange or automated quotation system, and to the extent
required by such exchange on which such Debentures are listed, the Company will notify such stock
exchange of any such notice of redemption. In addition, the Company will notify the New York Stock
Exchange or any other national securities exchange or automated quotation system on which such
Debentures are listed or quoted of the principal amount outstanding following any partial
redemption of the Debentures.

          SECTION 3.03.   Payment of Debentures Called for Redemption. If notice of redemption
has been given as provided in Section 3.02, the Debentures or portion of Debentures with respect to
which such notice has been given shall, unless converted pursuant to the terms hereof, become due
and payable on the date fixed for redemption and at the place or places stated in such notice at
the redemption price, plus interest accrued and unpaid to, but excluding, the redemption date
(unless the redemption date is after a Record Date and on or prior to the corresponding interest
payment date, in which event the interest will be paid on the interest payment date to the Holder
of record on the Record Date), and, unless the Company shall default in the payment of such
Debentures at the redemption price, plus interest, if any, accrued and unpaid to, but excluding,
such date, interest on the Debentures or portion of Debentures so called for redemption, interest
shall cease to accrue on and after such date and, after 5:00 p.m., New York City time, on the
Business Day immediately preceding the redemption date (unless the Company shall default in the
payment of such Debentures at the redemption price, together with interest accrued to such date)
and such Debentures shall cease to be convertible and, except as provided in Section 2.06 and
Section 8.02, to be entitled to any benefit or security under this Indenture, and the Holders
thereof shall have no right in respect of such Debentures except the right to receive the
redemption price thereof plus accrued and unpaid interest to, but excluding, the redemption date.
On presentation and surrender of such Debentures at a place of payment in said notice specified,
the said Debentures or the specified portions thereof shall be paid and redeemed by the Company at the redemption price, together with interest accrued and unpaid
thereon to, but excluding, the redemption date; provided that if the applicable redemption
date is after the applicable Record Date and on or before an interest payment date, the interest
payable on such interest payment date shall be paid on such interest payment date to the Holders of
record of such Debentures on the applicable Record Date instead of the Holders surrendering such
Debentures for redemption on such date.

          Upon presentation of any Debentures redeemed in part only, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of
the Company, a new Debentures or Debentures, of authorized denominations, in principal amount equal
to the unredeemed portion of the Debentures so presented.

          Notwithstanding the foregoing, the Trustee shall not redeem any Debentures or mail any notice
of redemption during the continuance of a Default in payment of interest on the Debentures. If any
Debentures called for redemption shall not be so paid upon surrender thereof for redemption on the
redemption date as provided in this Section 3.03, to the extent legally permissible, the redemption
price shall, until paid or duly provided for, bear interest from and

- 30 -

 

including the redemption date at a rate equal to 1% per annum above the rate borne by the Debentures and such Debentures shall
remain convertible into Common Stock until the redemption price and interest shall have been paid
or duly provided for.

          SECTION 3.04.   Repurchase at Option of Holders Upon a Fundamental Change. (a) If
there shall occur a Fundamental Change at any time prior to maturity of the Debentures, then each
Holder of Debentures shall have the right, at such Holder’s option, to require the Company to
repurchase all of such Holder’s Debentures, or any portion thereof that is a multiple of $1,000
principal amount, on a date (the “Fundamental Change Repurchase Date”) specified by the Company,
that is not less than 20 calendar days nor more than 35 calendar days after the date of the Company
Repurchase Notice related to such Fundamental Change at a cash repurchase price equal to 100% of
the principal amount of the Debentures being repurchased, plus accrued and unpaid interest to, but
excluding, the Fundamental Change Repurchase Date, subject to the satisfaction by the Holder of the
requirements set forth in Section 3.04(c); provided that if such Fundamental Change
Repurchase Date falls after a Record Date and on or prior to the corresponding interest payment
date, then the interest payable on such interest payment date shall be paid on such interest
payment date to the Holders of record of the Debentures on the applicable Record Date instead of
the Holders surrendering the Debentures for repurchase on such date.

          (b) On or before the fifth calendar day after the occurrence of a Fundamental Change, the
Company shall mail or cause to be mailed to all Holders of record of the Debentures on the date of
the Fundamental Change at their addresses shown in the Register (and to beneficial owners of the
Debentures as required by applicable law) a notice (a “Company Repurchase Notice”) as set forth in
Section 3.05 with respect to such Fundamental Change. The Company shall also deliver a copy of the
Company Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to
Holders of Debentures. Concurrently with the mailing of such Company Repurchase Notice, the
Company shall issue a press release announcing such Fundamental Change referred to in the Company
Repurchase Notice, the form and content of which press release shall be determined by the Company
in its sole discretion.

          No failure of the Company to give the foregoing notices and press release and no defect
therein shall limit the repurchase rights of Holders of Debentures or affect the validity of the
proceedings for the repurchase of the Debentures pursuant to this Section 3.04.

          (c) For Debentures to be repurchased at the option of the Holder, the Holder must deliver to
the Paying Agent, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding
the Fundamental Change Repurchase Date, (i) a written notice of repurchase (the “Repurchase
Notice”) in the form set forth on the reverse of the Debentures duly completed (if the Debentures
are certificated) or stating the following (if the Debentures are represented by a Global
Debenture): (A) the certificate number of the Debentures which the Holder will deliver to be
repurchased or compliance with the appropriate Depositary procedures, (B) the portion of the
principal amount of the Debentures which the Holder will deliver to be repurchased, which portion
must be in principal amounts of $1,000 or a whole multiple of $1,000 and (C) that such Debentures
shall be repurchased by the Company pursuant to the terms and conditions specified in the
Debentures and in this Indenture, together with (ii) such Debentures duly endorsed for transfer (if
the Debentures are certificated) or book-entry transfer of such

- 31 -

 

Debentures (if such Debentures are
represented by a Global Debenture). The delivery of such Debentures to the Paying Agent with, or
at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at
the office of the Paying Agent shall be a condition to the receipt by the Holder of the repurchase
price therefore; provided, however, that such repurchase price shall be so paid
pursuant to this Section 3.04 only if the Debentures so delivered to the Paying Agent shall conform
in all respects to the description thereof in the Repurchase Notice. All questions as to the
validity, eligibility (including time of receipt) and acceptance of any Debentures for repurchase
shall be determined by the Company, whose determination shall be final and binding absent manifest
error.

          (d) The Company shall repurchase from the Holder thereof, pursuant to this Section 3.04, a
portion of a Debenture, if the principal amount of such portion is $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to the repurchase of all of a Debenture also apply
to the repurchase of such portion of such Debenture.

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

          Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.04
shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Fundamental Change Repurchase Date and the time of the book-entry
transfer or delivery of the Debentures.

          If at any time of such Fundamental Change, any Debentures are listed or quoted on the New York
Stock Exchange or any other national securities exchange or automated quotation system, to the
extent required by such stock exchange or quotation system on which such Debentures are listed or
quoted, the Company will notify such stock exchange or quotation system that a Fundamental Change
has occurred and any relevant details relating to such Fundamental Change.

          SECTION 3.05.   Company Repurchase Notice. Each Company Repurchase Notice shall:

     (1) state the repurchase price and the Fundamental Change Repurchase Date to which the
Company Repurchase Notice relates;

     (2) state the circumstances constituting the Fundamental Change;

     (3) state that the repurchase price will be paid in cash;

     (4) state that Holders must exercise their right to elect repurchase prior to 5:00

Section 3.06;

     (9) state whether the Debentures are then convertible, the then applicable Conversion

Change transaction and expected changes in the cash, shares or other property deliverable
upon conversion of the Debentures as a result of the occurrence of the Fundamental Change;

     (10) that Debentures as to which a Repurchase Notice has been given may be converted
only if the Repurchase Notice is withdrawn in accordance with the terms of this Indenture;

     (11) state the amount of interest accrued and unpaid per $1,000 principal amount of
Debentures to, but excluding, the Fundamental Change Repurchase Date; and

     (12) state the CUSIP number of the Debentures.

A Company Repurchase Notice may be given by the Company or, at the Company’s request, the Trustee
shall give such Company Repurchase Notice in the Company’s name and at the Company’s expense;
provided, that the text of the Company Repurchase Notice shall be prepared by the Company.

          The Company will, to the extent applicable, comply with the provisions of Rule 13e-4 and Rule
14e-1 (or any successor provision) under the Exchange Act that may be applicable at the time of the repurchase of the Debentures, file the related Schedule TO (or
any successor schedule, form or report) under the Exchange Act and comply with all other federal
and state securities laws in connection with the repurchase of the Debentures.

          SECTION 3.06.   Effect of Repurchase Notice; Withdrawal. Upon receipt by the Paying
Agent of the Repurchase Notice specified in Section 3.04, the Holder of the Debentures in respect
of which such Repurchase Notice was given shall (unless such Repurchase Notice is validly withdrawn

price with respect to such Debentures. Such repurchase price shall be paid to such Holder, subject

the Fundamental Change Repurchase Date with respect to such Debentures (provided the Holder has
satisfied the conditions in Section 3.04) and (y) the time of book-entry transfer or delivery of
such Debentures to the Paying Agent by the Holder thereof in the manner required by Section 3.04.
The Debentures in respect of which a Repurchase Notice has been given by the Holder thereof may not

Notice unless such Repurchase Notice has first been validly withdrawn.

- 33 -

 

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

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

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

          If a Repurchase Notice is properly withdrawn, the Company shall not be obligated to repurchase
the Debentures listed in such Repurchase Notice.

          SECTION 3.07.   Deposit of Repurchase Price. Prior to 10:00 a.m., New York City time,
on the Fundamental Change Repurchase Date, the Company shall deposit with the Paying Agent or, if
the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section
2.06, an amount of cash (in immediately available funds if deposited on the Fundamental Change
Repurchase Date), sufficient to pay the aggregate repurchase price of all the Debentures or
portions thereof that are to be repurchased as of the Fundamental Change Repurchase Date.

          If on the Fundamental Change Repurchase Date the Paying Agent holds cash sufficient to pay the
repurchase price of the Debentures that Holders have elected to require the Company to repurchase
in accordance with Section 3.04, then, on the Fundamental Change Repurchase Date, such Debentures
will cease to be outstanding, interest will cease to accrue and all other rights of the Holders of
such Debentures will terminate, other than the right to receive the repurchase price upon delivery
or book-entry transfer of such Debentures. This will be the case whether or not book-entry
transfer of the Debentures has been made or the Debentures has been delivered to the Paying Agent.

          SECTION 3.08.   Debentures Repurchased in Part. Upon presentation of any Debentures
repurchased only in part, the Company shall execute and the Trustee shall authenticate and make
available for delivery to the Holder thereof, at the expense of the Company, a new Debenture or
Debentures, of any authorized denomination, in aggregate principal amount equal to the
unrepurchased portion of the Debentures presented.

          SECTION 4.01.   Payment of Debentures. The Company shall promptly pay the principal
of and interest on the Debentures on the dates and in the manner provided in the Debentures and in
this Indenture. Principal and interest shall be considered paid on the date due if on such date
the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not
prohibited from paying such money to the Debentureholders on that date pursuant to the terms of
this Indenture.

          The Company shall pay interest on overdue principal at the rate specified therefor in the
Debentures, and it shall pay interest on overdue installments of interest as specified in Section
2.13.

          SECTION 4.02.   Maintenance of Office or Agency. The Company will maintain an office
or agency in the Borough of Manhattan, The City of New York, where the Debentures may be
surrendered for registration of transfer or exchange or for presentation for payment or for
conversion, redemption or repurchase and where notices and demands to or upon the Company in
respect of the Debentures and this Indenture may be served. As of the date of this Indenture, such
office is located at the office of the Trustee located at The Bank of New York Mellon, 101 Barclay
Street, Floor 8W, New York, NY 10286, Attention: Corporate Trust Administration and, at any other
time, at such other address as the Trustee may designate from time to time by notice to the
Company. The Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency not designated or appointed by the Trustee. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office.

          The Company may also from time to time designate co-registrars and one or more offices or
agencies where the Debentures may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

          So long as the Trustee is the Registrar, the Trustee agrees to mail, or cause to be mailed,
the notices set forth in Section 7.08. If co-registrars have been appointed in accordance with
this Section, the Trustee shall mail such notices only to the Company and the Holders of Debentures
it can identify from its records.

          SECTION 4.03.   Reports. The Company covenants and agrees that it shall:

          (a) file with the Trustee, within 15 days after the Company is required to file the same with
the SEC, copies of the annual reports and of the information, documents and other reports (or
copies of such portions of any of the foregoing as the SEC may from time to time by rules and
regulations prescribe) which the Company is required to file with the SEC pursuant to

- 35 -

 

Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not required to file information,
documents or reports pursuant to either of Section 13 or Section 15(d) of the Exchange Act, then
the Company shall file with the Trustee and the SEC, in accordance with rules and regulations
prescribed from time to time by the SEC, such of the supplementary and periodic information,
documents and reports which may be required pursuant to Section 13 of the Exchange Act in respect
of a security listed and registered on a national securities exchange as may be prescribed from
time to time in such rules and regulations;

          (b) file with the Trustee and the SEC, in accordance with rules and regulations prescribed
from time to time by the SEC, such additional information, documents and reports with respect to
compliance by the Company with the conditions and covenants of this Indenture as may be required by
such rules and regulations;

          (c) transmit by mail, to all Debentureholders, as their names and addresses appear in the
Register of the Registrar, within 30 days after the filing thereof with the Trustee, such summaries
of any information, documents and reports required to be filed by the Company pursuant to clauses
(a) and (b) of this Section 4.03 as may be required by rules and regulations prescribed from time
to time by the SEC; and

          (d) comply with the other provisions of TIA Section 314(a).

          All information, documents and reports described in this Section 4.03 and filed with the SEC
pursuant to its Electronic Data Gathering, Analysis, and Retrieval system or any successor shall be
deemed to be filed with the Trustee and transmitted by mail to all Debentureholders, as applicable,
as of the time they are filed via such system. The Trustee shall have no duty to search for or
obtain any electronic or other filings that the Company makes with the SEC, regardless of whether
such filings are periodic, supplemental or otherwise.

          Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers’ Certificates).

          SECTION 4.04.   Existence. Subject to Article 5, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its existence and rights
(charter and statutory); provided that the Company shall not be required to preserve any
such right if the Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and that the loss thereof is not disadvantageous in any
material respect to the Holders of Debentures.

          SECTION 4.05.   Payment of Taxes and Other Claims. The Company will pay or discharge,
or cause to be paid or discharged, before the same may become delinquent, (i) all taxes,
assessments and governmental charges levied or imposed upon the Company or any Significant
Subsidiary or upon the income, profits or property of the Company or any Significant Subsidiary,
(ii) all claims for labor, materials and supplies which, if unpaid, might by law become a lien or
charge upon the property of the Company or any Significant Subsidiary and (iii)

- 36 -

 

all stamp taxes and other duties, if any, which may be imposed by the United States or any political subdivision
thereof or therein in connection with the issuance, transfer, exchange, conversion, redemption or
repurchase of any Debentures or with respect to this Indenture; provided that, in the case
of clauses (i) and (ii), the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim (A) if the failure to do so will not, in
the aggregate, have a material adverse impact on the Company, or (B) if the amount, applicability
or validity is being contested in good faith by appropriate proceedings.

          SECTION 4.06.   Compliance Certificate. The Company shall deliver to the Trustee
within 120 days after the end of each fiscal year of the Company an Officers’ Certificate stating
that a review of the Company’s activities during the preceding fiscal year has been made under the
supervision of the signing Officers with a view to determining whether the Company has kept,
observed, performed and fulfilled its obligations under this Indenture and further stating, as to
each such Officer signing such certificate, whether to the best of such Officer’s knowledge the
Company during such preceding fiscal year has kept, observed, performed and fulfilled each and
every such covenant contained in this Indenture and that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have knowledge of any
Default and whether or not the signers know of any Default that occurred during such period. If
they do know of any Default, the certificate shall describe the Default, its status and what action
the Company is taking or proposes to take with respect thereto. The Company also shall comply with
Section 314(a)(4) of the TIA.

          SECTION 4.07.   Further Instruments and Acts. The Company shall execute and deliver
such further instruments and do such further acts as may be reasonably necessary or proper to carry
out more effectively the purpose of this Indenture.

          SECTION 4.08.   Contingent Interest. Beginning with the six-month interest period
commencing September 15, 2016, the Company will pay interest (“Contingent Interest”) during any
six-month interest period if the Trading Price of the Debentures for each of the five Trading Days
ending on the second Trading Day immediately preceding the first day of the applicable six-month interest period equals or exceeds 120% of the principal amount of the
Debentures. During any six-month interest period when Contingent Interest is payable, the
Contingent Interest payable on each $1,000 principal amount of Debentures shall equal 0.25% of the
average Trading Price of $1,000 principal amount of Debentures during the five Trading Days ending
on the second Trading Day immediately preceding the first day of the applicable six-month interest
period used to determine whether Contingent Interest must be paid.

          The Trustee’s sole responsibility pursuant to this Section 4.08 shall be to obtain the Trading
Price of the Debentures for each of the five Trading Days immediately preceding the first day of
the applicable six-month interest period and to provide such information to the Company. The
Company shall determine whether Holders are entitled to receive Contingent Interest, and if so,
provide notice pursuant to Section 4.09. Notwithstanding any term contained in this Indenture or
any other document to the contrary, the Trustee shall have no responsibilities, duties or
obligations for or with respect to (i) determining whether the Company must pay Contingent Interest
or (ii) determining the amount of Contingent Interest, if any, payable by the Company.

- 37 -

 

          Contingent Interest for any period shall be paid on the same date and to the same Person
entitled to receive other interest payable on any Debentures. Contingent Interest due under this
Section 4.08 shall be treated for all purposes of this Indenture like any other interest accruing
on the Debentures.

          SECTION 4.09.   Contingent Interest Notification. Prior to the first Business Day of
a six-month interest period during which Contingent Interest will be paid, the Company will
disseminate a press release through BusinessWire (or if BusinessWire is no longer available, a
comparable wire service) stating that Contingent Interest will be paid on the Debentures and
identifying the six-month interest period.

          SECTION 4.10.   Tax Treatment. The Company agrees, and by acceptance of beneficial
ownership interest in the Debentures each Holder of the Debentures will be deemed to have agreed,
for U.S. federal income tax purposes (1) to treat the Debentures as indebtedness that is subject to
Treas. Reg. Sec. 1.1275-4 (the “Contingent Payment Regulations”) and, for purposes of the
Contingent Payment Regulations, to treat the cash and the fair market value of any stock
beneficially received by a Holder upon any conversion of the Debentures as a contingent payment and
(2) to be bound by the Company’s determination of the “comparable yield” and “projected payment
schedule,” within the meaning of the Contingent Payment Regulations, with respect to the
Debentures. A Holder may obtain the issue price, amount of original issue discount, issue date,
yield to maturity, comparable yield and projected payment schedule for the Debentures by submitting
a written request for such information to the Company at the following address: Wesco
International, Inc., 225 West Station Square Drive, Suite 700, Pittsburgh, PA 15219, Attention:
Investor Relations Department.

ARTICLE 5

Successor Company

          SECTION 5.01.   When Company May Merge or Transfer Assets. The Company shall not
consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all
of its assets to any Person unless:

          (a) either (i) the Company is the continuing corporation, or (ii) the resulting, surviving or
transferee person (if other than the Company) is a corporation or limited liability company
organized and existing under the laws of the United States, any state thereof or the District of
Columbia and such person assumes, by a supplemental indenture in a form reasonably satisfactory to
the Trustee, and a supplemental agreement, all of the Company’s obligations under the Debentures
and this Indenture;

          (b) immediately after giving effect to the transaction described above, no Default or Event of
Default, has occurred and is continuing;

          (c) if as a result of such transaction the Debentures become convertible into common stock or
other securities issued by a third party, such third party fully and unconditionally Guarantees all
obligations of the Company or such surviving Person under the Debentures and this Indenture; and

- 38 -

 

          (d) the Company has delivered to the Trustee the Officers’ Certificate and Opinion of Counsel
pursuant to Section 5.03.

          SECTION 5.02.   Successor to be Substituted. In case of any such consolidation,
merger, sale, conveyance, transfer or lease in which the Company is not the continuing corporation
and upon the assumption by the successor Person, by supplemental indenture, executed and delivered
to the Trustee and reasonably satisfactory in form and substance to the Trustee, of the due and
punctual payment of the principal of, premium, if any, and interest on all of the Debentures, and
the due and punctual performance and observance of all of the covenants and conditions of this
Indenture to be performed or satisfied by the Company, such successor Person shall succeed to and
be substituted for the Company, and may exercise every right and power of the Company, with the
same effect as if it had been named herein as the party of this first part, and, except in the case
of a lease, the Company shall be discharged from its obligations under the Debentures and this
Indenture. Such successor Person thereupon may cause to be signed, and may issue either in its own
name or in the name of the Company any or all of the Debentures, issuable hereunder that
theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the
order of such successor Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Debentures that previously shall have been signed and
delivered by the officers of the Company to the Trustee for authentication, and any Debentures that
such successor Person thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Debentures so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Debentures theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Debentures had been issued at the date of the execution hereof. In the event of any such
consolidation, merger, sale, conveyance or transfer, upon compliance with this Article 5 the Person
named as the “Company” in the first paragraph of this Indenture or any successor that shall
thereafter have become such in the manner prescribed in this Article 5 may be dissolved, wound up
and liquidated at any time thereafter and such Person shall be discharged from its liabilities as
obligor and maker of the Debentures and from its obligations under this Indenture.

          SECTION 5.03.   Opinion of Counsel to be Given Trustee. Prior to execution of any
supplemental indenture pursuant to this Article 5, the Trustee shall receive an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or lease and any such assumption complies with the provisions of this
Article 5.

ARTICLE 6

Defaults and Remedies

          SECTION 6.01.   Events of Default. An “Event of Default” occurs if:

          (a) the Company defaults in any payment of interest on any Debenture when the same becomes due
and payable and such default continues for a period of 30 days;

- 39 -

 

          (b) the Company defaults in the payment of the principal of and premium, if any, on, any

11.03;

          (d) the Company fails to deliver Common Stock (including any Additional Shares), or cash in
lieu thereof, or a combination of the foregoing, as required pursuant to Article 10 upon the
conversion of any Debentures and such failure continues for five days following the scheduled
settlement date for such conversion;

          (e) the Company fails to provide notice of the anticipated effective date or actual effective
date of a Fundamental Change on a timely basis as required in this Indenture;

          (f) the Company fails to comply with any of its agreements contained in the Debentures or this
Indenture (other than those referred to in (a), (b), (c), (d) or (e) above) and such failure
continues for 60 days after the notice specified below;

          (g) Indebtedness of the Company or any Significant Subsidiary is not paid within any
applicable grace period after final maturity or the acceleration of any such Indebtedness by the
Holders thereof because of a default and the total amount of such Indebtedness unpaid or
accelerated exceeds $35 million or its foreign currency equivalent at the time and such failure
continues for 10 days after the notice specified below;

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

          (1) commences a voluntary case;

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

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

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

          (5) or takes any comparable action under any foreign laws relating to insolvency;

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

          (1) is for relief against the Company or any Significant Subsidiary in an involuntary
case;

          (2) appoints a Custodian of the Company or any Significant Subsidiary or for any
substantial part of its property; or

- 40 -

 

          (3) orders the winding up or liquidation of the Company or any Significant Subsidiary;

          (4) or any similar relief is granted under any foreign laws and the order or decree
remains unstayed and in effect for 60 days;

          (j) any judgment or decree for the payment of money in excess of $35 million or its foreign
currency equivalent at the time is entered against the Company or any Significant Subsidiary and is
not discharged, waived or stayed and either (A) an enforcement proceeding has been commenced by any
creditor upon such judgment or decree or (B) there is a period of 60 days following the entry of
such judgment or decree during which such judgment or decree is not discharged, waived or the
execution thereof stayed and such judgment or decree is not discharged, waived or the execution
thereof stayed within 10 days after the notice specified below; or

          (k) the Distribution Guarantee shall be held in any judicial proceeding to be unenforceable or
invalid.

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

          The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal
or state law for the relief of debtors. The term “Custodian” means any receiver, trustee,
assignee, liquidator, custodian or similar official under any Bankruptcy Law.

          A Default under clause (f), (g) or (j) above is not an Event of Default until the Trustee or
the Debentureholders of at least 25% in principal amount of the outstanding Debentures notify the
Company of the Default and the Company does not cure such Default within the time specified after
receipt of such notice. Such notice must specify the Default, demand that it be remedied and state
that such notice is a “Notice of Default”.

          The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written
notice in the form of an Officers’ Certificate of any event which with the giving of notice or the
lapse of time would become an Event of Default under clause (f), (g) or (j), its status and what
action the Company is taking or proposes to take with respect thereto.

          SECTION 6.02.   Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(h) or (i) with respect to the Company) occurs and is continuing, the
Trustee by notice to the Company, or the Debentureholders of at least 25% in principal amount of
the outstanding Debentures by notice to the Company, may declare the principal of, premium, if any,
and accrued but unpaid interest on all the Debentures to be due and payable. Upon such a
declaration, such principal, premium, if any, and interest shall be due and payable immediately.
If an Event of Default specified in Section 6.01(h) or (i) with respect to the Company occurs, the
principal of, premium, if any, and interest on all the Debentures shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any
Debentureholders. The Debentureholders of a majority in principal

- 41 -

 

amount of the Debentures by
notice to the Trustee may rescind an acceleration and its consequences if the rescission (i) would
not conflict with any judgment or decree; (ii) if all existing Events of Default have been cured or
waived except nonpayment of principal, premium, if any, or interest that has become due solely
because of acceleration; and (iii) if the Company has paid the compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. No such rescission shall affect
any subsequent Default or impair any right consequent thereto.

          Notwithstanding anything to the contrary in this Indenture, the sole remedy for any Event of
Default from time to time relating to the Company’s failure to comply with its obligations under
Section 4.03, will, at the option of the Company, for the first 365 days after the occurrence of
such Event of Default, consist exclusively of the right to receive additional interest (the
“Additional Interest”) on the Debentures at an annual rate equal to 0.50% of the principal amount
of the Debentures. In order to elect to pay Additional Interest as the sole remedy during the first
365 days after the occurrence of an Event of Default described in the preceding sentence, the
Company must give notice to the Trustee and the Company will disseminate a press release through
BusinessWire (or if BusinessWire is no longer available, a comparable wire service) of such
election on or before the close of business on the fifth Business Day after the date on which such
Event of Default occurs. Upon the failure to timely give the Trustee such notice and disseminate
such press release, the Debentures will be subject to acceleration as provided in the first
paragraph of this Section 6.02. A failure by the Company to pay Additional Interest when due and
payable and such default continues for a period of 30 days, shall constitute an Event of Default subject to Section 6.01(a) which will be subject to acceleration as
provided in the first paragraph of this Section 6.02.

          Additional Interest will be payable in the same manner and on the same interest payment dates
and subject to the same terms as other interest payable under this Indenture. Additional Interest
will accrue on all outstanding Debentures from and including the date on which an Event of Default
first occurs to, but not including, the 365th day thereafter (or such earlier date on
which the Event of Default relating to Section 4.03 shall have been cured or waived). If the Event
of Default relating to Section 4.03 is cured or waived prior to such 365th day, such
Additional Interest will cease to accrue on the date of such cure or waiver. On such
365th day (if the Event of Default is continuing), such Additional Interest will cease
to accrue and the Debentures will be subject to acceleration as provided in the first paragraph of
this Section 6.02. A Debentureholder’s right to receive Additional Interest for an Event of Default
will not affect the rights of the Debentureholders in the event of an occurrence of any other Event
of Default.

          SECTION 6.03.   Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, or
interest on the Debentures or to enforce the performance of any provision of the Debentures or this
Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Debentures or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any
Debentureholder 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

- 42 -

 

Event of Default. No remedy is exclusive of any other remedy. All
available remedies are cumulative. 

          SECTION 6.04.   Waiver of Past Defaults. Subject to Section 6.02, the Holders of a
majority in principal amount of the Debentures by notice to the Trustee may waive an existing
Default and its consequences except (i) a Default in the payment of the principal of, premium, if
any, or interest on a Debenture, (ii) a Default arising from the failure to redeem or repurchase
any Debenture when required pursuant to the terms of this Indenture, (iii) a Default arising from
the failure of the Company to deliver Common Stock (including any Additional Shares), or cash in
lieu thereof, or a combination of the foregoing, as applicable upon the conversion of any
Debentures pursuant to the terms of this Indenture or (iv) a Default in respect of a provision that
under Section 9.02 cannot be amended without the consent of each Debentureholder affected. When a
Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

          SECTION 6.05.   Control by Majority. The Debentureholders of a majority in principal
amount of the Debentures may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture
or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of
other Debentureholders or would involve the Trustee in personal liability; provided,
however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.

          SECTION 6.06.   Limitation on Suits. Except to enforce the right to receive payment
of principal, premium, if any, or interest when due or to receive Common Stock (including any
Additional Shares), or cash in lieu thereof, or a combination of the foregoing, as applicable upon
the conversion of any Debentures pursuant to the terms of this Indenture, no Debentureholder may
pursue any remedy with respect to this Indenture or the Debentures unless:

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

          (b) the Debentureholders of at least 25% in principal amount of the Debentures make a written
request to the Trustee to pursue the remedy;

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

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

          (e) the Debentureholders of a majority in principal amount of the Debentures do not give the
Trustee a direction inconsistent with the request during such 60-day period.

- 43 -

 

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

          Notwithstanding any other provision of this Indenture and any provision of any Debentures, the
right of any Debentureholder to receive payment of the principal of (including the redemption price
or repurchase price upon redemption or repurchase pursuant to Article 3), premium, if any, and
accrued interest on such Debentures, on or after the respective due dates expressed in such
Debentures or in the event of redemption or repurchase, or to institute suit for the enforcement of
any such payment on or after such respective dates against the Company, or to receive Common Stock
(including any Additional Shares), or cash in lieu thereof, or a combination of the foregoing, as
applicable upon the conversion of any Debentures pursuant to the terms of this Indenture, or to
bring suit for enforcement of such conversion rights, shall not be impaired or affected without the
consent of such holder.

          Anything contained in this Indenture or the Debentures to the contrary notwithstanding, the
Holder of any Debentures, without the consent of either the Trustee or the Holder of any other
Debentures, on its own behalf and for its own benefit, may enforce, and may institute and maintain
any proceeding suitable to enforce, its rights of conversion as provided herein.

          SECTION 6.07.   Rights of Debentureholders to Receive Payment and to Convert.
Notwithstanding any other provision of this Indenture, the right of any Debentureholder to receive
payment of principal of and liquidated damages and interest on the Debentures held by such
Debentureholder, on or after the respective due dates expressed in the Debentures, or to bring suit
for the enforcement of any such payment on or after such respective dates, or to receive Common
Stock (including any Additional Shares), or cash in lieu thereof, or a combination of the
foregoing, as applicable upon the conversion of any Debentures pursuant to the terms of this
Indenture, or to bring suit for enforcement of such conversion rights, shall not be impaired or
affected without the consent of such Debentureholder.

          SECTION 6.08.   Collection Suit by Trustee. If an Event of Default specified in
Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount then due and owing
(together with interest on any unpaid interest to the extent lawful) and the amounts provided for
in Section 7.07.

          SECTION 6.09.   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 and the Debentureholders allowed in any judicial proceedings relative to the Company,
Distribution, their creditors or their property and, unless prohibited by law or applicable
regulations, may vote on behalf of the Debentureholders in any election of a trustee in bankruptcy
or other Person performing similar functions, and any Custodian in any such judicial proceeding is
hereby authorized by each Debentureholder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the Debentureholders, to pay
to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under
Section 7.07.

- 44 -

 

          SECTION 6.10.   Priorities. Subject to Article 12, if the Trustee collects any money
or property pursuant to this Article 6, it shall pay out the money or property in the following
order:

          FIRST: to the Trustee for amounts due under Section 7.07;

          SECOND: to Debentureholders for amounts due and unpaid on the Debentures for principal
and interest, ratably without preference or priority of any kind, according to the amounts
due and payable on the Debentures for principal and interest, respectively; and

          THIRD: to the Company.

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

          SECTION 6.11.   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, 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 does not apply to a suit by the Trustee, a suit by a Debentureholder
pursuant to Section 6.07 or a suit by Debentureholders of more than 10% in principal amount of the
Debentures or to any suit instituted by any holder of Debentures for the enforcement of the payment
of the principal of, or premium, if any, or interest on any Debentures on or after the due date
expressed in such Debentures or to any suit for the enforcement of the right to convert any
Debentures in accordance with the provisions of Article 10.

          SECTION 6.12.   Waiver of Stay, Extension or Usury Laws. Neither the Company nor
Distribution (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law
wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company and Distribution (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder,
delay or impede the execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

Trustee

          SECTION 7.01.   Duties of Trustee. (a) If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and

- 45 -

 

use the same degree of care and skill in its exercise as a prudent Person would exercise or
use under the circumstances in the conduct of such Person’s own affairs.

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

     (1) the Trustee need only perform such duties as are specifically set forth in this
Indenture and no implied covenants or obligations shall be read into this Indenture against
the Trustee; and

     (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. However, the Trustee shall examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein).

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

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

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

     (3) the Trustee shall not be liable with respect to any action it takes or omits to
take in good faith in accordance with a direction received by it pursuant to Section 6.05.

          (d) Every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section.

Trustee may agree in writing with the Company.

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

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

          (h) Every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section and to the
provisions of the TIA.

- 46 -

 

          SECTION 7.02.   Rights of Trustee. (a) The Trustee may conclusively rely and shall
be protected in acting or refraining from acting on any document believed by it to be genuine and
to have been signed or presented by the proper person. The Trustee need not investigate any fact
or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers.

          (e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to
legal matters relating to this Indenture and the Debentures shall be full and complete
authorization and protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such counsel.

          (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, debenture, note or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see
fit. If the Trustee shall determine to make such further inquiry or investigation, then, except as
otherwise prohibited by applicable law or as would reasonably be expected to violate or result in
the loss or impairment of any attorney-client or work product privilege, the Trustee 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; provided, however, that the
Company shall not be required to provide access or furnish information in the event of any
litigation involving this Indenture or the Debentures except pursuant to applicable rules of
discovery.

          (g) 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 Debentureholders pursuant to
the provisions of this Indenture, unless such Debentureholders shall have offered to the Trustee
security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which
may be incurred therein or thereby.

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

- 47 -

 

          (i) 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.

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

          (k) In no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

          SECTION 7.03.   Individual Rights of Trustee. The Trustee in its individual or any
other capacity may become the owner or pledgee of Debentures and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee. Any
conversion agent, Paying Agent, Registrar or co-paying agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

          SECTION 7.04.   Trustee’s Disclaimer. The Trustee shall not be responsible for and
makes no representation as to the validity or adequacy of this Indenture or the Debentures, it
shall not be accountable for the Company’s use of the proceeds from the Debentures, and it shall
not be responsible for any statement of the Company in this Indenture or in any document issued in
connection with the sale of the Debentures or in the Debentures other than the Trustee’s
certificate of authentication.

          SECTION 7.05.   Notice of Defaults. (a) The Trustee shall not be deemed to have
notice of any Default, other than a payment default, unless a Responsible Officer shall have been
advised in writing that a Default has occurred. No duty imposed upon the Trustee in this Indenture
shall be applicable with respect to any Default of which the Trustee is not deemed to have notice.

          (b) If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Debentureholder notice of the Default within the earlier of 90 days after it occurs or
30 days after it is known to a Responsible Officer or written notice of it is received by the
Trustee. Except in the case of a Default in payment of principal, premium, if any, or interest on
any Debenture (including payments pursuant to the redemption provisions of such Debenture), the
Trustee may withhold notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding notice is in the interests of the Debentureholders.

          SECTION 7.06.   Reports by Trustee to Debentureholders. As promptly as practicable
after each March 15, beginning with March 15, 2010, and in any event prior to December 31 in each
subsequent year, the Trustee shall, to the extent that any of the events described in TIA § 313(a)
occurred within the previous twelve months, but not otherwise, mail to

- 48 -

 

each Debentureholder a brief report dated as of March 15 that complies with Section 313(a) of
the TIA. The Trustee shall also comply with Section 313(b) of the TIA.

          A copy of each report at the time of its mailing to Debentureholders shall be filed with the
SEC and each stock exchange (if any) on which the Debentures are listed. The Company agrees to
notify promptly the Trustee, in writing, whenever the Debentures become listed on any stock
exchange and of any delisting thereof.

          SECTION 7.07.   Compensation and Indemnity. The Company shall pay to the Trustee from
time to time such compensation as the Company and the Trustee shall from time to time agree in
writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee
of an express trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the
compensation for its services. Such expenses shall include the reasonable compensation and
expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.
The Company and Distribution, jointly and severally shall indemnify the Trustee, and hold it
harmless, against any and all loss, liability or expense (including reasonable attorneys’ fees)
incurred by or in connection with the offer and sale of the Debentures or the administration of
this trust and the performance of its duties hereunder. The Trustee shall notify the Company of
any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof;
provided, however, that any failure so to notify the Company shall not relieve the
Company or Distribution of its indemnity obligations hereunder. The Company shall defend the claim
and the indemnified party shall provide reasonable cooperation at the Company’s expense in the
defense. Such indemnified parties may have separate counsel and the Company and Distribution, as
applicable, shall pay the fees and expenses of such counsel; provided, however,
that the Company shall not be required to pay such fees and expenses if it assumes such indemnified
parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of
interest between the Company and Distribution, as applicable, and such parties in connection with
such defense. The Company need not reimburse any expense or indemnify against any loss, liability
or expense incurred by an indemnified party through such party’s own willful misconduct and
negligence.

          To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Debentures on all money or property held or collected by the Trustee other than money
or property held in trust to pay principal of and interest and any liquidated damages on particular
Debentures.

          The Company’s payment obligations pursuant to this Section shall survive the satisfaction or
discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy
law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01(h) or (i) with respect to the Company, the
expenses are intended to constitute expenses of administration under the Bankruptcy Law.

          SECTION 7.08.   Replacement of Trustee. The Trustee may resign at any time by so
notifying the Company. The Holders of a majority in principal amount of the Debentures may

- 49 -

 

remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The
Company shall remove the Trustee if:

          (a) the Trustee fails to comply with Section 7.10;

          (b) the Trustee is adjudged bankrupt or insolvent;

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

          (d) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Debentures and such Debentureholders do not reasonably promptly appoint a successor
Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event
being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

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

          If a successor Trustee does not take office within 60 days after the retiring Trustee resigns
or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Debentures may
petition any court of competent jurisdiction for the appointment of a successor Trustee.

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

          Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

          SECTION 7.09.   Successor Trustee by Merger. If the Trustee consolidates with, merges
or converts into, or transfers all or substantially all of its corporate trust business or assets
to, another corporation or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Trustee.

          In case at the time such successor or successors by merger, conversion or consolidation to the
Trustee shall succeed to the trusts created by this Indenture any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Debentures so authenticated; and in
case at that time any of the Debentures shall not have been authenticated, any successor to the
Trustee may authenticate such Debentures either in the name

- 50 -

 

of any predecessor hereunder or in the name of the successor to the Trustee; and in all such
cases such certificates shall have the full force which it is anywhere in the Debentures or in this
Indenture provided that the certificate of the Trustee shall have.

          SECTION 7.10.   Eligibility; Disqualification. The Trustee shall at all times satisfy
the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at
least $100,000,000 as set forth in its most recent published annual report of condition. The
Trustee shall comply with TIA § 310(b); provided, however, that there shall be
excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

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

ARTICLE 8

Discharge of Indenture

          SECTION 8.01.   Discharge of Liability on Debentures. (a) When (i) the Company
delivers to the Trustee all outstanding Debentures (other than Debentures replaced pursuant to
Section 2.09) for cancellation or (ii) all outstanding Debentures have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption or upon a repurchase
pursuant to Article 3 hereof, and the Company irrevocably deposits with the Trustee money
sufficient to pay at maturity or upon redemption or repurchase all outstanding Debentures,
including interest thereon to maturity or such redemption or repurchase date (other than Debentures
replaced pursuant to Section 2.09), and any shares of Common Stock or other property due in respect
of converted Debentures, and if in each such case the Company pays all other sums payable hereunder
by the Company, then this Indenture shall, subject to Section 8.01(b), cease to be of further
effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of
the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and
expense of the Company.

          (b) Notwithstanding clause (a) above, the Company’s obligations in Sections 2.05, 2.06, 2.07,
2.08, 2.09, 2.10, 7.07, 7.08 and in this Article 8 shall survive until the Debentures have been
paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.03 and 8.04 shall survive.

          SECTION 8.02.   Application of Trust Money. The Trustee shall hold in trust money and
any shares of Common Stock or other property due in respect of converted Debentures deposited with
it pursuant to this Article 8. It shall apply the deposited money through the Paying Agent and in
accordance with this Indenture to the payment of principal of and interest on the Debentures or, in
the case of any shares of Common Stock or other property due in respect of converted Debentures, in
accordance with this Indenture in relation to the

- 51 -

 

conversion of Debentures pursuant to the terms hereof. Money and securities so held in trust
are not subject to Article 12.

          SECTION 8.03.   Repayment to Company. The Trustee and the Paying Agent shall promptly
turn over to the Company upon request any excess money or securities held by them at any time.

          Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Company upon written request any money held by them for the payment of principal or interest
and any shares of Common Stock or other property due in respect of converted Debentures that
remains unclaimed for two years, and, thereafter, Debentureholders entitled to the money and/or
securities must look to the Company for payment as general creditors.

          SECTION 8.04.   Reinstatement. If the Trustee or Paying Agent is unable to apply any
money or to deliver any shares of Common Stock or other property due in respect of converted
Debentures in accordance with this Article 8 by reason of any legal proceeding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company’s obligations under this Indenture and the Debentures
shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until
such time as the Trustee or Paying Agent is permitted to apply all such money and any shares of
Common Stock or other property due in respect of converted Debentures in accordance with this
Article 8; provided, however, that, if the Company has made any payment of interest
on or principal of any Debentures because of the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Debentureholders of such Debentures to receive such
payment from the money held by the Trustee or Paying Agent.

     (j) make any change adversely affecting the rights of Holders of the Debentures with
respect to the Distribution Guarantee; or

     (k) make any change in Section 6.04 or 6.07 or the second sentence of this Section

          It shall not be necessary for the consent of the Debentureholders under this Section 9.02 to
approve the particular form of any proposed amendment, but it shall be sufficient if such consent
approves the substance thereof.

          An amendment under this Section 9.02 may not make any change that adversely affects the rights
under Article 12 of any holder of Senior Indebtedness then outstanding unless the holders of such
Senior Indebtedness (or any group or representative thereof authorized to give a consent) consent

evidences the same debt as the consenting Debentureholder’s Debenture, even if notation of the
consent or waiver is not made on the Debenture. However, any such Debentureholder or subsequent
Debentureholder may revoke the consent or waiver as to such Debentureholder’s Debenture or portion
of the Debenture if the Trustee receives the notice of revocation before the date the amendment or
waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every
Debentureholder. An amendment or waiver becomes effective once both (i) the requisite number of
consents have been received by the Company or the Trustee and (ii) such amendment or waiver has
been executed by the Company, Distribution (if applicable) and the Trustee.

          The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Debentureholders entitled to give their consent or take any other action described
above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding the immediately preceding paragraph, those Persons who were Debentureholders
at such record date (or their duly designated proxies), and only those Persons, shall be entitled
to give such consent or to revoke any consent previously given or to take any such action, whether
or not such Persons continue to be Debentureholders after such record date. No such consent shall
be valid or effective for more than 120 days after such record date.

          SECTION 9.05.   Notation on or Exchange of Debentures. If an amendment changes the
terms of a Debenture, the Trustee may require the Debentureholder of the Debenture to deliver it to
the Trustee. The Trustee may place an appropriate notation on the Debenture regarding the changed
terms and return it to the Debentureholder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Debenture shall issue and the Trustee shall
authenticate a new Debenture that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Debenture shall not affect the validity of such amendment.

          SECTION 9.06.   Trustee to Sign Amendments. The Trustee shall sign any amendment
authorized pursuant to this Article 9 if the amendment does not adversely affect the rights,
duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign
it. In signing such amendment the Trustee shall be entitled to receive, and (subject to Section
7.01) shall be fully protected in relying upon, in addition to the documents required by Section
13.04, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized
or permitted by this Indenture and that such amendment is the legal, valid and binding obligation
of the Company and Distribution enforceable against them in accordance with its terms, subject to
customary exceptions, and complies with the provisions hereof (including Section 9.03).

ARTICLE 10

Conversion of Debentures

          SECTION 10.01.   Right to Convert. (a) Subject to and upon compliance with the
provisions of this Indenture, on or prior to the close of business on the Trading Day immediately
preceding September 15, 2029, the Holder of any Debentures not previously redeemed or repurchased
shall have the right, at such Holder’s option, to convert the principal amount of the Debentures
held by such Holder, or any portion of such principal amount which is

- 55 -

 

an integral multiple of $1,000, into cash and, if applicable, fully paid and non-assessable
shares of Common Stock (as such shares shall then be constituted) as described in Section 10.12, at
the Conversion Rate in effect at such time, by surrender of the Debentures so to be converted in
whole or in part, together with any required funds, under the circumstances described in this
Section 10.01 and in the manner provided in Section 10.02. The Debentures shall be convertible
only upon the occurrence of one of the following events:

     (1) prior to September 15, 2028 on any date during any Fiscal Quarter beginning after
September 30, 2009 (and only during such Fiscal Quarter), if the Closing Sale Price of a
share of Common Stock was more than 130% of the then current Conversion Price for at least
20 Trading Days in the 30 consecutive Trading-Day period ending on the last Trading Day of
the immediately preceding Fiscal Quarter;

     (2) on or after September 15, 2028;

     (3) with respect to Debentures called for redemption pursuant to Section 3.01, until
5:00 p.m., New York City time, on the Business Day prior to the relevant redemption date;

     (4) if the Company distributes to all or substantially all holders of Common Stock
rights, options or warrants (other than pursuant to a shareholder rights plan) entitling
them to purchase, for a period of 45 calendar days or less, Common Stock at a price less
than the average of the Closing Sale Prices per share of the Common Stock for the 10 Trading
Days preceding the declaration date for such distribution;

     (5) if the Company distributes to all or substantially all holders of Common Stock,
cash or other assets, debt securities or rights to purchase the Company’s securities (other
than pursuant to a shareholder rights plan, share split of Common Stock or a dividend or
distribution on its Common Stock in shares of Common Stock), which distribution has a per
share value as determined by the Board of Directors exceeding 5% of the Closing Sale Price
per share of the Common Stock on the Trading Day preceding the declaration date for such
distribution;

     (6) if a Fundamental Change occurs, at any time beginning on the Business Day following
the effective date of the Fundamental Change until 5:00 p.m., New York City time, on the
Business Day preceding the Fundamental Change Repurchase Date relating to such Fundamental
Change;

     (7) if the Company consolidates with or merges with or into another Person or is a
party to a binding share exchange or conveys, transfers, sells, leases or otherwise disposes
of all or substantially all of its properties and assets in each case in a transaction not
constituting a Fundamental Change, in each case pursuant to which the Common Stock would be
converted into cash, securities and/or other property; or

     (8) during the five consecutive Trading-Day period immediately following any five
consecutive Trading Day period in which the Trading Price per $1,000 principal amount of the
Debentures was less than 98% of the product of the Closing Sale Price of a

- 56 -

 

share of Common Stock and the applicable Conversion Rate for each day of such five
consecutive Trading-Day period.

          (b) (1) The Company shall notify the Trustee in writing on or prior to the fifth Business Day
following the first day of each calendar quarter (commencing prior to September 15, 2028, beginning
with the calendar quarter ending December 31, 2009) whether the condition to conversion set forth
in Section 10.01(a)(1) above shall have been satisfied with respect to such calendar quarter.

          (2) The Trustee shall have no obligation to determine the Trading Price of the Debentures and
whether the Debentures are convertible pursuant to clause (8) of Section 10.01(a) unless the
Company has requested such determination; and the Company shall have no obligation to make such
request unless a Holder of the Debentures makes a request for a determination and provides the
Company with reasonable evidence that the Trading Price per $1,000 principal amount of Debentures
is reasonably likely to be less than 98% of the product of the Closing Sale Price of the Common
Stock and the Conversion Rate then in effect per $1,000 principal amount of Debentures. At such
time, the Company shall instruct the Trustee to determine the Trading Price of the Debentures
beginning on the next Trading Day and on each successive Trading Day for 10 consecutive Trading
Days to determine whether the Trading Prices for the Debentures for each Trading Day in any five
consecutive Trading-Day period within such 10 Trading-Day period is less than 98% of the product of
the Closing Sale Price of the Common Stock and the then current Conversion Rate, and to notify the
Company accordingly.

          The Trustee shall be entitled at its sole discretion to consult with the Company and to
request the assistance of the Company in connection with the Trustee’s duties and obligations
pursuant to Section 10.01(b)(1) and Section 10.01(b)(2) hereof (including without limitation the
calculation or determination of the Conversion Price, the Conversion Rate, the Closing Sale Price
and the Trading Price), and the Company agrees, if requested by the Trustee, to cooperate with, and
provide assistance to, the Trustee in carrying out its duties under this Section 10.01. Upon
determination of the Conversion Price, the Conversion Rate, the Closing Sale Price or the Trading
Price, as the case may be, the Trustee shall notify the Company in writing of such determination
and, in the case of the determination of the Conversion Price, the Conversion Rate or the Closing
Sale Price, upon request the Company shall promptly confirm such determination in writing to the
Trustee.

          (c) In the case of a distribution contemplated by clauses (4) or (5) of Section 10.01(a), the
Company shall notify Debentureholders at least 20 calendar days prior to the ex-dividend date (the
first date on which the Common Stock trades, regular way, on the relevant market from which the
Closing Sale Price was obtained without the right to receive such right, warrant, dividend or
distribution) for such distribution (the “Distribution Notice”). Once the Company has given the
Distribution Notice, Debentureholders may surrender their Debentures for conversion at any time
until the earlier of (i) 5:00 p.m., New York City time, on the Business Day immediately preceding
the ex-dividend date or (ii) the Company’s announcement that such distribution will not take place.
In the event of a distribution contemplated by clauses (4) or (5) of Section 10.01(a),
Debentureholders may not convert their Debentures if the Holders may otherwise participate in such
distribution without converting their Debentures. The Company

- 57 -

 

will provide written notice to the Trustee and Holders and any conversion agent as soon as
reasonably practicable of any anticipated or actual event or transaction that will cause or causes
the Debentures to become convertible pursuant to clauses (4) or (5) of Section 10.01(a).

          (d) In the event of a transaction contemplated by clause 7 of Section 10.01(a),
Debentureholders shall have the right to convert their Debentures at any time beginning 15 calendar
days prior to the date announced by the Company as the anticipated effective date of the
transaction and until and including the date which is 15 calendar days after the date that is the
actual effective date of such transaction. The Board of Directors shall determine the anticipated
effective date of the transaction, and such determination shall be conclusive and binding on the
Debentureholders and shall be publicly announced by the Company and posted on its website not later
than 20 calendar days prior to such date.

          (e) Whenever the Debentures shall become convertible pursuant to this Section 10.01, the
Company or, at the Company’s request, the Trustee in the name and at the expense of the Company,
shall notify the Holders of the event triggering such convertibility in the manner provided in
Section 13.02, and the Company shall also publicly announce such information and publish it on the
Company’s website. Any notice so given shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. The Company shall notify Debentureholders at least
20 calendar days prior to the anticipated effective date of any Fundamental Change.

          (f) Debentures in respect of which a Holder has delivered a Repurchase Notice exercising such
Holder’s right to require the Company to repurchase such Debentures pursuant to Section 3.04 may be
converted only if such Repurchase Notice is withdrawn in accordance with Section 3.06 prior to 5:00
p.m., New York City time, on the Business Day immediately preceding the Fundamental Change
Repurchase Date.

          (g) A Holder of Debentures is not entitled to any rights of a Holder of Common Stock until
such Holder has converted his Debentures to Common Stock, and only to the extent such Debentures
are deemed to have been converted to Common Stock under this Article 10.

          SECTION 10.02.   Exercise of Conversion Right; Issuance of Common Stock on Conversion; No
Adjustment for Interest or Dividends. In order to exercise the conversion right with respect
to any Debentures in certificated form, the Company must receive at the office or agency of the
Company maintained for that purpose in The City of New York or, at the option of such
Debentureholder, the Corporate Trust Office, such Debentures with the original or facsimile of the
form entitled “Conversion Notice” on the reverse thereof, duly completed and manually signed,
together with such Debentures duly endorsed for transfer, together with any other required transfer
documents, accompanied by the funds, if any, required by this Section 10.02. Such notice shall
also state the name or names (with address or addresses) in which any certificate or certificates
for shares of Common Stock which shall be issuable on such conversion shall be issued, and shall be
accompanied by transfer or similar taxes, if required pursuant to Section 10.07.

- 58 -

 

          In order to exercise the conversion right with respect to any interest in a Global Debenture,
the Holder must complete, or cause to be completed, the appropriate instruction form for conversion
pursuant to the Depositary’s book-entry conversion program; deliver, or cause to be delivered, by
book-entry delivery an interest in such Global Debenture; furnish appropriate endorsements and
transfer documents if required by the Company or the Trustee or conversion agent; and pay the
funds, if any, required by this Section 10.02 and any transfer or similar taxes if required
pursuant to Section 10.07.

          The cash and, if applicable, a certificate or certificates for the number of full shares of
Common Stock into which the Debentures are converted (and cash in lieu of fractional shares) will
be delivered to such Holder after satisfaction of the requirements for conversion set forth above,
in accordance with Section 10.12. In case any Debentures of a denomination greater than $2,000 and
integral multiples of $1,000 in excess thereof shall be surrendered for partial conversion, and
subject to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of the Debentures so surrendered, without charge to the Holder, a new Debenture or
Debentures in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Debentures.

          Each conversion shall be deemed to have been effected as to any such Debentures (or portion
thereof) on the date on which the requirements set forth above in this Section 10.02 have been
satisfied as to such Debentures (or portion thereof) (the “Conversion Date”) and such Debentures
will be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the
Conversion Date. The Person in whose name any certificate or certificates for shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become, on said date, the
holder of record of the shares represented thereby; provided that any such surrender on any
date when the stock transfer books of the Company shall be closed shall constitute the Person in
whose name the certificates are to be issued as the record holder thereof for all purposes on the
next succeeding day on which such stock transfer books are open, but such conversion shall be at
the Conversion Rate in effect on the Conversion Date.

          Any Debentures or portion thereof surrendered for conversion during the period from 5:00 p.m.,
New York City time, on the Record Date for any interest payment date to 5:00 p.m., New York City
time, on the Business Day preceding the applicable interest payment date shall be accompanied by
payment, in immediately available funds or other funds acceptable to the Company, of an amount
equal to the interest otherwise payable on such interest payment date on the principal amount being
converted; provided that no such payment need be made (1) if a Holder converts its
Debentures in connection with a redemption and the Company has specified a redemption date that is
after a Record Date and on or prior to the next interest payment date, (2) if a Holder converts its
Debentures in connection with a Fundamental Change and the Company has specified a Fundamental
Change Repurchase Date that is after a Record Date and on or prior to the corresponding interest
payment date or (3) to the extent of any overdue interest, if any overdue interest exists at the
time of conversion with respect to such Debentures. Except as provided above in this Section 10.02
and Section 10.05, no payment or other adjustment shall be made for interest accrued on any
Debentures converted or for dividends on any shares issued upon the conversion of such Debentures
as provided in this Article 10.

- 59 -

 

          Upon the conversion of an interest in a Global Debenture, the Trustee (or other conversion
agent appointed by the Company), or the custodian for the Global Debenture at the direction of the
Trustee (or other conversion agent appointed by the Company), shall make a notation on such Global
Debenture as to the reduction in the principal amount represented thereby. The Company shall
notify the Trustee in writing of any conversions of Debentures effected through any conversion
agent other than the Trustee.

          Upon the conversion of any Debentures, the accrued but unpaid interest attributable to the
period from the issue date of the Debentures to the Conversion Date, with respect to the converted
Debentures, shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be
paid in full to the Holder thereof through delivery of the cash (including a cash payment in lieu
of fractional shares, if any) and shares of Common Stock, if any, in exchange for the Debentures
being converted pursuant to the provisions hereof.

          SECTION 10.03.   Cash Payments in Lieu of Fractional Shares. No fractional shares of
Common Stock or scrip certificates representing fractional shares shall be issued upon conversion
of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the
same Holder, the number of full shares that shall be issuable upon conversion shall be computed on
the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the
extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon
the conversion of any Debenture or Debentures, the Company shall make an adjustment and payment
therefor in cash to the Holder of Debentures at a price equal to the Closing Sale Price on the last
Trading Day immediately preceding the Conversion Date.

          SECTION 10.04.   Conversion Rate.

          (a) Each $1,000 principal amount of the Debentures shall be convertible into cash and the
number of shares of Common Stock, if any, based upon the Conversion Rate which is specified in the
form of Debentures attached as Exhibit A hereto, subject to adjustment as provided in this Section
10.04 and Section 10.05.

          (b) Prior to September 15, 2016, if and only to the extent a Holder elects to convert
Debentures at any time following the date on which a Non-Stock Change of Control becomes effective
(the “Effective Date”) but before 5:00 p.m., New York City time, on the Business Day immediately
preceding the related Fundamental Change Purchase Date, the Company shall increase the Conversion
Rate applicable to such converted Debentures by a number of additional shares of Common Stock (the
“Additional Shares”) as set forth below. The number of additional shares of Common Stock shall be
determined by reference to the table below, based on the Effective Date and the price (the “Stock
Price”) paid per share for the Common Stock in the Non-Stock Change of Control. If holders of
Common Stock receive only cash in the Non-Stock Change of Control, the Stock Price shall be the
cash amount paid per share. Otherwise, the Stock Price shall be the average of the Closing Sale
Prices of the Common Stock on the five Trading Days prior to but not including the Effective Date
of such Non-Stock Change of Control.

          The Stock Price of Common Stock set forth in the table below, and clauses (ii) and (iii) in
the second succeeding paragraph below, shall be adjusted as of any date on which the

- 60 -

 

Conversion Rate is adjusted. The adjusted Stock Prices equal the Stock Prices applicable
immediately prior to such adjustment multiplied by a fraction, of which

     (1) the numerator shall be the Conversion Rate immediately prior to the adjustment
giving rise to the adjustment of the Stock Prices and

     (2) the denominator shall be the Conversion Rate as so adjusted.

The numbers of Additional Shares of Common Stock set forth in the table below shall be adjusted as
of any date on which the Conversion Rate is adjusted in the same manner in which the Conversion
Rate is adjusted.

          The following table sets forth the Stock Price and number of Additional Shares by which the
Conversion Rate shall be adjusted:

          If the Stock Price and Effective Date are not set forth on the table above and the Stock Price
is:

     (i) between two Stock Prices on the table or the Effective Date is between two
days on the table, the number of Additional Shares of Common Stock shall be
determined by the Trustee by straight-line interpolation between the number of
Additional Shares of Common Stock set forth for the higher and lower Stock Price and
the two Effective Dates, as applicable, based on a 360-day year;

     (ii) in excess of $161.6475 per share (subject to adjustment), no Additional
Shares of Common Stock shall be added to the Conversion Rate; or

     (iii) less than $23.0925 per share (subject to adjustment), no Additional
Shares of Common Stock shall be added to the Conversion Rate.

- 61 -

 

          Notwithstanding the foregoing, in no event will the Conversion Rate as adjusted pursuant to
this Section 10.04 exceed 43.3041 per $1,000 principal amount of the Debentures, subject to
adjustment in the same manner as the Conversion Rate as set forth in Section 10.05.

          The Company shall provide written notice to all Debentureholders and to the Trustee at least
20 calendar days prior to the anticipated Effective Date of a Non-Stock Change of Control. The
Company must also provide written notice to all Holders and to the Trustee upon the effectiveness
of such Non-Stock Change of Control.

          SECTION 10.05.   Adjustment of Conversion Rate. The Conversion Rate shall be adjusted
from time to time by the Company as follows:

          (a) If the Company shall issue to all or substantially all holders of Common Stock shares of
Common Stock as a dividend or distribution on shares of Common Stock, or shall effect a subdivision
or combination of Common Stock, then the Conversion Rate will be adjusted based on the following
formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to 9:00 a.m., New York
City time, on the Ex-Dividend Date for such dividend or distribution or the
effective date of such subdivision or combination, as applicable;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at 9:00 a.m., New York City time, on
the Ex-Dividend Date for such dividend or distribution or the effective date of
such subdivision or combination, as applicable;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or
distribution or the effective date of such subdivision or combination, as
applicable; and
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock that would be outstanding
immediately after, and solely as a result of, such event.

Such adjustment shall become effective at 9:00 a.m., New York City time, on (x) the Ex-Dividend
Date for such dividend or distribution or (y) the effective date of such subdivision or
combination. If any dividend or distribution described in this Section 10.05(a) is declared but not
so paid or made, the Conversion Rate shall be readjusted, effective as of the date the Board of
Directors publicly announces its decision not to make such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. For purposes of this Section 10.05(a), the number of shares of Common Stock outstanding
immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or
distribution shall not include Common Stock held in treasury, if any. The

 - 62 - 

 

Company will not pay any dividend or make any distribution on Common Stock held in treasury, if
any.

          (b) If the Company shall issue to all or substantially all holders of Common Stock any rights
or warrants entitling them to purchase, for a period of forty-five (45) calendar days or less,
shares of Common Stock at a price per share less than the average of the Closing Sale Prices of the
Common stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the declaration date for the issuance of such rights or warrants of Common
Stock, then the Conversion Rate will be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to 9:00 a.m., New York
City time, on the Ex-Dividend Date for such issuance;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at 9:00 a.m., New York City time, on
the Ex-Dividend Date for such issuance;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
9:00 a.m., New York City time, on the Ex-Dividend Date for such issuance;
	 
	 	 	 	 
	X

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

	 	=
	 	the number of shares of Common Stock equal to the aggregate price
payable to exercise such rights or warrants divided by the average of the Closing
Sale Prices of Common Stock over the ten consecutive Trading Day period ending on,
and including, the Trading Day immediately preceding the declaration date for the
issuance of such rights or warrants.

Such adjustment shall become effective immediately at 9:00 a.m., New York City time, on the
Ex-Dividend Date for such issuance. In the event that such rights or warrants described in this
Section 10.05(b) are not so issued, the Conversion Rate shall be readjusted, effective as of the
date the Board of Directors publicly announces its decision not to issue such rights or warrants,
to the Conversion Rate that would then be in effect if such distribution had not been declared. To
the extent that such rights or warrants are not exercised prior to their expiration or shares of
Common Stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of
such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would
then be in effect had the adjustments made upon the issuance of such rights or warrants been made
on the basis of the delivery of only the number of shares of Common Stock actually delivered. In
determining the aggregate price payable for such shares of Common Stock, there shall be taken into
account any consideration received for such rights or warrants and the value

 - 63 - 

 

of such consideration (if other than cash, to be determined by the Board of Directors). For
purposes of this Section 10.05(b), the number of shares of Common Stock outstanding immediately
prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such issuance shall not include
Common Stock held in treasury, if any. The Company will not issue any such rights or warrants in
respect of Common Stock held in treasury, if any.

          (c) If the Company shall distribute to all or substantially all holders of Common Stock,
shares of the Capital Stock (other than Common Stock), evidences of the Company’s indebtedness or
assets, including securities, but excluding:

     (1) any dividends or distributions referred to in Section 10.05(a);

     (2) the rights and warrants referred to in Section 10.05(b);

     (3) any dividends or distributions paid referred to in Section 10.05(d);

     (4) any dividends and distributions in connection with a Reorganization Event pursuant
to Section 10.06; or

     (5) any Spin-Off to which the provisions set forth below in this Section 10.05(c)
apply,

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

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to 9:00 a.m., New York
City time, on the Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at 9:00 a.m., New York City time, on
the Ex-Dividend Date for such distribution;
	 
	 	 	 	 
	SP0

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

	 	=
	 	the Fair Market Value (as determined by the Board of Directors), on
the Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness or
assets so distributed, expressed as an amount per share of Common Stock.

     Such adjustment made pursuant to the preceding paragraph of this Section 10.05(c) shall become
effective at 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution. In the
event that such distribution described in the preceding paragraph of this

 - 64 - 

 

Section 10.05(c) is not so made, the Conversion Rate shall be readjusted, effective as of the
date the Board of Directors publicly announces its decision not to effect such distribution, to the
Conversion Rate which would then be in effect if such distribution had not been declared.

     If the transaction that gives rise to an adjustment pursuant to this Section 10.05(c) is,
however, one pursuant to which the payment of a dividend or other distribution on Common Stock
consists of shares of Capital Stock of, or similar equity interests in, a Subsidiary or other
business unit of the Company (a “Spin-Off”) that are, or, when issued, will be, traded or quoted on
the New York Stock Exchange or any other national or regional securities exchange or market, then
the Conversion Rate will instead be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to 9:00 a.m., New York
City time, on the Ex-Dividend Date for the Spin-Off;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at 9:00 a.m., New York City time, on
the Ex-Dividend Date for the Spin-Off;
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Closing Sale Prices of the Capital Stock or similar
equity interests distributed to holders of Common Stock applicable to one share of
Common Stock over the 10 consecutive Trading Day period commencing on and including
the effective date of the Spin-Off (the “Valuation Period”); and
	 
	 	 	 	 
	MP0

	 	=
	 	the average of the Closing Sale Prices of Common Stock over the
Valuation Period.

Such adjustment made pursuant to the preceding paragraph of this Section 10.05(c) shall be made
immediately prior to 9:00 a.m., New York City time, on the Trading Day after the last day of the
Valuation Period, but will be given effect at 9:00 a.m., New York City time, on the Ex-Dividend
Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than ten Trading Days
prior to, and including, the end of the applicable Conversion Period in respect of any conversion,
references within this Section 10.05(c) to ten Trading Days shall be deemed replaced, for purposes
of calculating the affected applicable Conversion Rates in respect of that conversion, with such
lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the
Spin-Off to, and including, the last Trading Day of such applicable Conversion Period. For purposes
of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading
Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this
Section 10.05(c) related to Spin-Offs to ten Trading Days shall be deemed replaced with such lesser
number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off
to, but excluding, the relevant Conversion Date. In the event that such Spin-Off described in the
preceding paragraph of this Section 10.05(c) is not so made, the Conversion Rate shall be
readjusted, effective as of the date

 - 65 - 

 

the Board of Directors publicly announces its decision not to effect such Spin-Off, to be the
Conversion Rate which would then be in effect if such Spin-Off had not been declared.

          (d) If the Company pays any dividends or other distributions consisting exclusively of cash to
all or substantially all holders of Common Stock (other than dividends or distributions made in
connection with the Company’s liquidation, dissolution or winding-up or upon a Reorganization
Event), then the Conversion Rate will be adjusted based on the following formula:

     where

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to 9:00 a.m., New
York City time, on the Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at 9:00 a.m., New York City time,
on the Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Closing Sale Prices of Common Stock over the ten
consecutive Trading-Day period ending on, and including, the Trading Day
immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	 
	 	 	 	 
	C

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

Such adjustment pursuant to the preceding paragraph of this Section 10.05(d) shall become effective
at 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution. In the
event that any distribution described in this Section 10.05(d) is not so made, the Conversion Rate
shall be readjusted, effective as of the date the Board of Directors publicly announces its
decision not to pay such dividend or distribution, to be the Conversion Rate which would then be in
effect if such dividend or distribution had not been declared.

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

     where

 - 66 - 

 

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect at 5:00 p.m., New York City time, on the
Expiration Date;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after 5:00 p.m. New York
City time, on the Expiration Date;
	 
	 	 	 	 
	FMV

	 	=
	 	the Fair Market Value (as determined by the Board of Directors), on
the Expiration Date, of the aggregate value of all cash and any other consideration
paid or payable for shares validly tendered or exchanged and not withdrawn as of
the Expiration Date;
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding immediately after
the last time tenders or exchanges may be made pursuant to such tender offer or
exchange offer (after giving effect to the purchase or exchange of shares pursuant
thereto) (the “Expiration Time”);
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
the Expiration Time; and
	 
	 	 	 	 
	SP’

	 	=
	 	the average of the Closing Sale Prices of Common Stock over the 10
consecutive Trading Day period commencing on the Trading Day immediately succeeding
the Expiration Date.

Such adjustment pursuant to the preceding paragraph of this Section 10.05(e) shall become effective
immediately after 5:00 p.m., New York City time, on the Expiration Date. If the Trading Day next
succeeding the Expiration Date is less than ten Trading Days prior to, and including, the end of
the applicable Conversion Period in respect of any conversion, references within this Section
10.05(e) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected
applicable Conversion Rates in respect of that conversion, with such lesser number of Trading Days
as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and
including, the last Trading Day of such Conversion Period. For purposes of determining the
applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on
the Trading Day next succeeding the Expiration Date, references within this Section 10.05(e) to ten
Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from,
and including, the Trading Day next succeeding the Expiration Date to, but excluding, the relevant
Conversion Date. In the event that the Company is, or one of the Company’s Subsidiaries is,
obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer,
but the Company is, 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 be
readjusted to be the Conversion Rate which would then be in effect if such tender offer or exchange
offer had not been made. Except as set forth in the preceding sentence, if the application of this
Section 10.05(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
10.05(e).

 - 67 - 

 

          (f) In cases where the Fair Market Value of assets, debt securities or certain rights,
warrants or options to purchase the Company’s securities, applicable to one share of Common Stock,
distributed to all or substantially all stockholders:

         (i) equals or exceeds the average Closing Sale Price of Common Stock over the
ten consecutive Trading-Day period ending on, and including, the Trading Day
immediately preceding the Ex-Dividend Date for such distribution, or

          (ii) such average Closing Sale Price exceeds the Fair Market Value of such
assets, debt securities or rights, warrants or options so distributed by less than
$1.00,

rather than being entitled to an adjustment in the Conversion Rate, the Holder of a Debenture will
be entitled to receive upon conversion, in addition to the cash equal to the Cash Conversion
Settlement Amount, the kind and amount of assets, debt securities or rights, warrants or options
comprising the distribution, if any, that such Holder would have received if such Holder had
converted such Debentures solely into Common Stock immediately prior to the record date for
determining the stockholders entitled to receive the distribution.

          (g) For purposes of this Section 10.05, the following terms shall have the meaning indicated:

          (i) “Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller
in an arm’s-length transaction, as determined by the Board of Directors.

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

          (iii) “Trading Day” means a day during which (i) trading in the Common Stock generally occurs,
(ii) there is no Market Disruption Event and (iii) a Closing Sale Price for the Common Stock is
provided on the New York Stock Exchange or, if the Common Stock is not listed on the New York Stock
Exchange, on the principal other U.S. national or regional securities exchange on which the Common
Stock is then listed or, if the Common Stock is not listed on a U.S. national or regional
securities exchange, on the principal other market on which the Common Stock is then traded.

          (h) The Company may make such increases in the Conversion Rate, in addition to those required
by Section 10.05(a)-(e), as the Board of Directors considers to be advisable to avoid or diminish
any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event treated as such
for income tax purposes.

- 68 -

 

          To the extent permitted by applicable law, the Company from time to time may increase the
Conversion Rate by any amount for any period of time if the period is at least 20 Business Days,
the increase is irrevocable during the period and the Board of Directors shall have made a
determination that such increase would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence,
the Company shall mail to Holders of record of the Debentures a notice of the increase, which
notice will be given at least 15 days prior to the effectiveness of any such increase, and such
notice shall state the increased Conversion Rate and the period during which it will be in effect.

          (i) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that
any adjustments that by reason of this Section 10.05(i) are not required to be made shall be
carried forward and the Company shall make such carry forward adjustments, regardless of whether
the aggregate adjustment is less than 1%, (x) annually on the anniversary of the Settlement Date
and otherwise (y)(1) five Business Days prior to the maturity of the Debentures (whether at stated
maturity or otherwise) or (2) prior to the redemption date or Fundamental Change Repurchase Date,
unless such adjustment has already been made. All calculations under this Article 10 shall be made
by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth
(1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase
Common Stock pursuant to a Company plan for reinvestment of dividends or interest or, except as
otherwise provided in this Section 10.05, for any issuance of Common Stock or convertible or
exchangeable securities or rights to purchase Common Stock or convertible or exchangeable
securities. Interest will not accrue on any cash into which the Debentures are convertible.

          (j) Whenever the Conversion Rate is adjusted as herein provided, the Company will issue a
press release through BusinessWire containing the relevant information and make this information
available on the Company’s website or through another public medium as the Company may use at that
time. In addition, the Company shall promptly file with the Trustee and any conversion agent other
than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment
and setting forth a brief statement of the facts requiring such adjustment. Unless and until a
Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee
shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that
the last Conversion Rate of which it has actual knowledge is still in effect. Promptly after
delivery of such certificate, the Company shall prepare a notice of such adjustment of the
Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the
Holder of each Debentures at his last address appearing on the Register, within 20 calendar days
after execution thereof. Failure to deliver such notice shall not affect the legality or validity
of any such adjustment.

          (k) In any case in which this Section 10.05 provides that an adjustment shall become effective
at 9:00 a.m., New York City time, on (i) the Ex-Dividend Date for a dividend or distribution
described in Section 10.05(a), 10.05(c) and 10.05(d), (ii) the effective date for a subdivision or
combination of Common Stock described in Section 10.05(a), (iii) the Ex-Dividend Date for the
determination of stockholders entitled to receive rights or warrants

- 69 -

 

pursuant to Section 10.05(b), or (iv) the Expiration Date for any tender or exchange offer
pursuant to Section 10.05(e), (each a “Determination Date”), the Company may elect to defer until
the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the
Holder of any Debentures converted after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock, if any, or other securities issuable upon
such conversion by reason of the adjustment required by such Adjustment Event over and above the
Common Stock, if any, issuable upon such conversion before giving effect to such adjustment and (y)
paying to such Holder any amount in cash in lieu of any fractional share pursuant to Section 10.03.
For purposes of this Section 10.05(k), the term “Adjustment Event” shall mean:

     (1) in any case referred to in clause (i) hereof, the date any such dividend or
distribution is paid or made,

     (2) in any case referred to in clause (ii) hereof, the occurrence of such event,

     (3) in any case referred to in clause (iii) hereof, the date of expiration of such
rights or warrants, and

     (4) in any case referred to in clause (iv) hereof, the date a purchase or exchange of
Common Stock pursuant to such tender offer or exchange offer is consummated and becomes
irrevocable.

     (l) For purposes of this Section 10.05, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.
The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company.

     (m) No adjustment to the Conversion Rate shall be made pursuant to this Section 10.05 if the
Holders of the Debentures may participate in the transaction that would otherwise give rise to
adjustment pursuant to this Section 10.05, without conversion of such Holder’s Debentures, on an
“as converted” basis (i.e., as though such Holder had exchanged each $1,000 principal amount of its
Debentures immediately prior to the record date for such transaction for a number of shares of
Common Stock equal to the then applicable Conversion Rate). In no event will the Company adjust
the Conversion Rate to the extent that the adjustment would reduce the Conversion Price below the
par value per share of Common Stock. In addition, the applicable Conversion Rate will not be
adjusted:

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

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

- 70 -

 

          (iii) for a change in the par value of Common Stock..

          (n) Whenever any provision of this Indenture requires the Company to calculate an average of
Closing Sale Prices of Common Stock over multiple days, the Company will make appropriate
adjustments (determined by the Board of Directors) to account for any adjustment to the Conversion
Rate that becomes effective or any event requiring an adjustment to the Conversion Rate where the
Ex-Dividend Date of the event occurs at any time during the period during which the average is to
be calculated. In addition, if during a period applicable for calculating the Daily VWAP or Closing
Sale Price of Common Stock an event occurs that requires an adjustment to the Conversion Rate, the
Daily VWAP or Closing Sale Price of Common Stock shall be calculated for such period in a manner
determined by the Company to appropriately reflect the impact of such event on the price of Common
Stock during such period.

          SECTION 10.06.   Effect of Reclassification, Consolidation, Merger or Sale. If any of
the following events occur:

          (a) any reclassification or change of the outstanding 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) any consolidation or merger of the Company with or into another Person or any sale, lease,
transfer, conveyance or other disposition of all or substantially all of the Company’s assets and
those of its Subsidiaries taken as a whole to any other Person or Persons,

and, in each case, the holders of Common Stock receive stock, other securities or other property or
assets (including cash or any combination thereof) with respect to or in exchange for such Common
Stock, (any such event or transaction, a “Reorganization Event”), in each case, the Company or the
successor purchasing corporation, as the case may be, shall execute with the Trustee a supplemental
indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of
such supplemental indenture, if such supplemental indenture is then required to so comply)
providing that such Debentures shall, without the consent of any Debentureholders, upon the
occurrence of any event that triggers a conversion right and during the periods set forth in the
description of such triggering event, in each case, as described in this Article 10, become
convertible in accordance with the procedures set forth in Section 10.02, except that the Daily
Conversion Value will be based on only the kind and amount of the consideration that the holders of
Common Stock received in such reclassification, change, consolidation, merger, sale, lease,
transfer, conveyance or other disposition (such consideration, the “Reference Property”). If the
Reorganization Event causes the Common Stock to be converted into the right to receive more than a
single type of consideration (determined based in part upon any form of stockholder election), the
Reference Property into which the Debentures will be convertible will be deemed to be the kind and
amount of consideration elected to be received by the holders of a majority of the Common Stock who
voted for such an election (if electing between two types of consideration) or the holders of a
plurality of the Common Stock who voted for such an election (if electing between more than two
types of consideration), as the case may be. In all cases, the provisions under Section 10.12
hereof relating to the Company’s conversion obligation shall continue to apply with respect to the
calculation of the conversion Settlement Amount, with the Daily Conversion Value, Daily Settlement
Amount and the Daily

- 71 -

 

VWAP based on the Reference Property; provided, however, that, if the holders of
Common Stock received only cash in a Reorganization Event, the conversion Settlement Amount shall
equal the Conversion Rate in effect on the Conversion Date multiplied by the price paid per share
of Common Stock in such Reorganization Event, and settlement shall occur on the third Trading Day
following the Conversion Date. The Company hereby agrees not to become a party to any such
transaction unless its terms are consistent with the foregoing in all material respects. Such
supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 10. If, in the case of any such
reclassification, change, consolidation, merger, sale, lease, transfer, conveyance or other
disposition, the stock or other securities and assets receivable thereupon by a holder of Common
Stock includes shares of stock or other securities and assets of a corporation other than the
successor or purchasing corporation, as the case may be, in such reclassification, change,
consolidation, merger, sale, lease, transfer, conveyance or other disposition, then such
supplemental indenture shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Debentures as the Board of
Directors shall reasonably consider necessary by reason of the foregoing, including to the extent
practicable the provisions
 providing for the conversion rights set forth in this Article 10.

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

          The above provisions of this Section 10.06 shall similarly apply to successive
reclassifications, changes, consolidations, mergers, sales, leases, transfers, conveyances or other
dispositions.

          If this Section 10.06 applies to any event or occurrence, Section 10.05 shall not apply. Any
Additional Shares of Common Stock that a Holder is entitled to receive upon conversion pursuant to
Section 10.04(b), if applicable, shall not be payable in shares of Common Stock, but shall
represent a right to receive the aggregate amount of cash, securities or other property into which
the additional shares of Common Stock would convert as a result of such recapitalization, change,
consolidation, merger, sale, lease, transfer, conveyance or other disposition.

          The Company agrees that it will not agree to be party to any Reorganization Event unless the
terms of this Section 10.06 are satisfied including any successor or purchasing company entering
into the supplemental indenture contemplated by this Section 10.06.

          SECTION 10.07.   Taxes on Shares Issued. The issue of stock certificates on
conversions of Debentures shall be made without charge to the converting Holder of Debentures for
any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The
Company shall not, however, be required to pay any such tax which may be payable in respect of any
transfer involved in the issue and delivery of stock in any name other than that of the Holder of
any Debentures converted, and the Company shall not be required to issue or deliver any such stock
certificate unless and until the Person or Persons requesting the issue thereof shall have

- 72 -

 

paid to the Company the amount of such tax or shall have established to the satisfaction of
the Company that such tax has been paid.

          SECTION 10.08.   Reservation of Shares, Shares to be Fully Paid; Compliance with
Governmental Requirements; Listing of Common Stock. The Company shall provide, free from
preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient
shares of Common Stock to provide for the conversion of the Debentures, including any additional
shares, from time to time as such Debentures are presented for conversion.

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

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

          The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Debentures hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly issued upon conversion,
the Company will in good faith and as expeditiously as possible, to the extent then permitted by
the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such
registration or approval, as the case may be.

          The Company further covenants that, if at any time the Common Stock shall be listed on the New
York Stock Exchange or any other national securities exchange or automated quotation system, the
Company will, if permitted by the rules of such exchange or automated quotation system, list and
keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation
system, all Common Stock issuable upon conversion of the Debentures; provided that if the
rules of such exchange or automated quotation system permit the Company to defer the listing of
such Common Stock until the first conversion of the Debentures into Common Stock in accordance with
the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon
conversion of the Debentures in accordance with the requirements of such exchange or automated
quotation system at such time.

          SECTION 10.09.   Responsibility of Trustee. The Trustee and any other conversion
agent shall not at any time be under any duty or responsibility to any Holder of Debentures to
determine the Conversion Rate or whether any facts exist which may require any adjustment of the
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when
made, or with respect to the method employed, or herein or in any supplemental indenture provided
to be employed, in making the same. The Trustee and any other conversion agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any shares of Common
Stock, or of any capital stock, other securities or other assets or property, which may at any time
be issued or delivered upon the conversion of any

- 73 -

 

Debentures; and the Trustee and any other conversion agent make no representations with
respect thereto. Neither the Trustee nor any conversion agent shall be responsible for any failure
of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or
other securities or property or cash upon the surrender of any Debentures for the purpose of
conversion or to comply with any of the duties, responsibilities or covenants of the Company
contained in this Article 10. Without limiting the generality of the foregoing, neither the
Trustee nor any conversion agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to Section 10.06
relating either to the kind or amount of shares of capital stock or other securities or other
assets or property (including cash) receivable by Holders of Debentures upon the conversion of
their Debentures after any event referred to in such Section 10.06 or to any adjustment to be made
with respect thereto, but, subject to the provisions of Section 9.01, may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in relying upon, the
Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.

          SECTION 10.10.   Notice to Holders Prior to Certain Actions. In case:

          (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 10.05; or

          (b) the Company shall authorize the granting to the holders of all or substantially all of its
Common Stock or rights or warrants to subscribe for or purchase any share of any class or any other
rights or warrants; or

          (c) of any reclassification or reorganization of the Common Stock of the Company (other than a
subdivision or combination of its outstanding Common Stock, or a change in par value, or from par
value to no par value, or from no par value to par value), or of any consolidation or merger to
which the Company is a party and for which approval of any stockholders of the Company is required,
or of the sale or transfer of all or substantially all of the assets of the Company; or

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

the Company shall cause to be filed with the Trustee and to be mailed to each Holder of Debentures
at his address appearing on the Register provided for in Section 2.05 of this Indenture, as
promptly as possible but in any event at least ten calendar days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer,

- 74 -

 

dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such dividend, distribution, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

          SECTION 10.11.   Stockholder Rights Plans. If the rights provided for in any future
rights plan adopted by the Company have separated from the shares of Common Stock in accordance
with the provisions of the applicable stockholder rights agreement so that the Holders of the
Debentures would not be entitled to receive any rights in respect of Common Stock issuable upon
conversion of the Debentures, the Conversion Rate will be adjusted as provided in Section 10.05(c).
If such rights have not separated, any shares of Common Stock delivered upon the conversion of
Debentures shall be accompanied by such rights.

          SECTION 10.12.   Settlement Upon Conversion. Upon any conversion of Debentures, the
Company will deliver to converting Holders in respect of each $1,000 principal amount of Debentures
being converted a “Settlement Amount” equal to the sum of the Daily Settlement Amount for each of
the 20 Trading Days during the Cash Settlement Averaging Period.

          “Daily Settlement Amount”, for each $1,000 principal amount of Debentures, for each of the 20
Trading Days during the Cash Settlement Averaging Period, shall consist of:

          (i) cash equal to the lesser of $50 and the Daily Conversion Value; and

          (ii) to the extent the Daily Conversion Value exceeds $50, a number of shares equal to,
(A) the difference between the Daily Conversion Value and $50, divided by (B) the Daily VWAP
of the Common Stock for such day.

          “Daily Conversion Value” means, for each of the 20 consecutive Trading Days during the Cash
Settlement Averaging Period, one-twentieth (1/20) of the product of (1) the applicable Conversion
Rate and (2) the Closing Sale Prices of the Common Stock (or the consideration into which the
Common Stock has been converted in connection with transactions to which Section 10.06 is
applicable) on such day. For the purposes of determining the Daily Conversion Value the following
provisions shall apply: (i) if the Reference Property includes securities for which the price can
be determined in a manner contemplated by the definition of “Closing Sale Price,” then the value of
such securities shall be determined in accordance with the principles set forth in such definition;
(ii) if the Reference Property includes other property (other than securities as to which clause
(i) applies or cash), then the value of such property shall be the fair market value of such
property as determined by the Company’s Board of Directors in good faith; and (iii) if the
Reference Property includes cash, then the value of such cash shall be the amount thereof.

          “Daily VWAP” for any Trading Day means the per share volume weighted average price of the
Common Stock on that day as displayed under the heading Bloomberg VWAP on Bloomberg Page WCC.N
<equity> AQR (or its equivalent successor page if such page is not available) in respect of
the period from the scheduled open of trading on the relevant Trading Day until the scheduled close
of trading on the relevant Trading Day (or if such volume weighted average price is unavailable,
the market price of one share of the Common Stock on

- 75 -

 

such Trading Day determined, using a volume weighted average method, by a nationally
recognized investment banking firm retained by the Company for this purpose).

          The Settlement Amount will be delivered to converting Holders on the third Business Day
immediately following the last day of the Cash Settlement Averaging Period.

ARTICLE 11

Distribution Guarantee

          SECTION 11.01.   Distribution Guarantee. Distribution hereby unconditionally and
irrevocably guarantees, as a primary obligor and not merely as a surety, to each Debentureholder
and to the Trustee and its successors and assigns (a) the full and punctual payment of principal
of, premium, if any, and interest on the Debentures when due, whether at Stated Maturity, by
acceleration, by redemption, repurchase, upon conversion or otherwise, and all other monetary
obligations of the Company under this Indenture (including obligations to the Trustee) and the
Debentures and (b) the full and punctual performance within applicable grace periods of all other
obligations of the Company, whether for expenses, indemnification or otherwise, under this
Indenture and the Debentures (all the foregoing being hereinafter collectively called the
“Guaranteed Obligations”). Distribution further agrees that the Guaranteed Obligations may be
extended or renewed, in whole or in part, without notice or further assent from Distribution, and
that Distribution shall remain bound under this Article 11 notwithstanding any extension or renewal
of any Guaranteed Obligation.

          Distribution waives presentation to, demand of, payment from and protest to the Company of any
of the Guaranteed Obligations and also waives notice of protest for nonpayment. Distribution
waives notice of any default under the Debentures or the Guaranteed Obligations. The obligations
of Distribution hereunder shall not be affected by (a) the failure of any Debentureholder or the
Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any
other Person under this Indenture, the Debentures or any other agreement or otherwise; (b) any
extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any
of the terms or provisions of this Indenture, the Debentures or any other agreement; (d) the
release of any security held by any Debentureholder or the Trustee for the Guaranteed Obligations
or any of them; (e) the failure of any Debentureholder or Trustee to exercise any right or remedy
against any other guarantor of the Guaranteed Obligations; or (f) any change in the ownership of
Distribution, except as provided in Section 11.03(b).

          Distribution hereby waives any right to which it may be entitled to have the assets of the
Company first be used and depleted as payment of the Company’s or Distribution’s obligations
hereunder prior to any amounts being claimed from or paid by Distribution hereunder. Distribution
hereby waives any right to which it may be entitled to require that the Company be sued prior to an
action being initiated against Distribution.

          Distribution further agrees that its Distribution Guarantee herein constitutes a guarantee of
payment, performance and compliance when due (and not a guarantee of collection)

- 76 -

 

and waives any right to require that any resort be had by any Debentureholder or the Trustee
to any security held for payment of the Guaranteed Obligations.

          The Distribution Guarantee is, to the extent and in the manner set forth in Article 12,
subordinated and subject in right of payment to the prior payment in full of the principal of and
premium, if any, and interest on all Senior Indebtedness of Distribution and is made subject to
such provisions of this Indenture.

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

          Distribution agrees that its Distribution Guarantee shall remain in full force and effect
until payment in full of all the Guaranteed Obligations. Distribution further agrees that its
Distribution Guarantee herein shall continue to be effective or be reinstated, as the case may be,
if at any time payment, or any part thereof, of principal of or interest on any Guaranteed
Obligation is rescinded or must otherwise be restored by any Debentureholder or the Trustee upon
the bankruptcy or reorganization of the Company or otherwise.

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

          Distribution agrees that it shall not be entitled to any right of subrogation in relation to
the Debentureholders in respect of any Guaranteed Obligations guaranteed hereby until payment in
full of all Guaranteed Obligations and all obligations to which the Guaranteed Obligations are
subordinated as provided in Article 12. Distribution further agrees that, as between it, on the
one hand, and the Debentureholders and the Trustee, on the other hand, (x) the maturity of the
Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the
purposes of the Distribution Guarantee herein, notwithstanding any stay,

- 77 -

 

injunction or other prohibition preventing such acceleration in respect of the Guaranteed
Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such
Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due
and payable) shall forthwith become due and payable by Distribution for the purposes of this
Section 11.01.

          Distribution also agrees to pay any and all costs and expenses (including reasonable
attorneys’ fees and expenses) incurred by the Trustee or any Debentureholder in enforcing any
rights under this Section 11.01.

          Distribution shall execute and deliver such further instruments and do such further acts as
may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

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

          SECTION 11.03.   When Distribution May Merge or Transfer Assets. (a) Distribution
shall not consolidate with, or merge with or into, or convey, transfer or lease all or
substantially all of its assets to any Person unless:

     (1) either (i) Distribution is the continuing corporation, or (ii) the resulting,
surviving or transferee person (if other than the Company) is a corporation or limited
liability company organized and existing under the laws of the United States, any state
thereof or the District of Columbia and such person assumes, by a supplemental indenture in
a form reasonably satisfactory to the Trustee, all of Distribution’s obligations under the
Distribution Guarantee and this Indenture;

     (2) immediately after giving effect to the transaction described above, no Default or
Event of Default, has occurred and is continuing; and

     (3) Distribution has delivered to the Trustee the Officers’ Certificate and Opinion of
Counsel, if any, requested pursuant to Section 11.03(c).

            (b) In case of any such consolidation, merger, sale, conveyance, transfer or lease in which
Distribution is not the continuing corporation and upon the assumption by the successor Person, by
supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form
and substance to the Trustee, of the Guaranteed Obligations and the observance of all of the
covenants and conditions of this Indenture to be performed or satisfied by Distribution, such
successor Person shall succeed to and be substituted for Distribution, with the same effect as if
it had been named herein as the party of this first part, and, except in the case of a lease,
Distribution shall be discharged from its obligations under the Distribution Guarantee and this
Indenture. In the event of any such consolidation, merger, sale, conveyance or transfer, upon
compliance with this Section 11.03 the Person named as

- 78 -

 

“Distribution” in the first paragraph of this Indenture or any successor that shall thereafter
have become such in the manner prescribed in this Section 11.03 may be dissolved, wound up and
liquidated at any time thereafter and such Person shall be discharged from its liabilities as
obligor in respect of the Guaranteed Obligations and from its obligations under this Indenture.

          (c) Prior to execution of any supplemental indenture pursuant to this Article 5, if so
requested by the Trustee, the Trustee shall receive an Officers’ Certificate and an Opinion of
Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or
lease and any such assumption complies with the provisions of this Section 11.03.

          (d) This Article 11 shall be binding upon Distribution and its successors and assigns and
shall inure to the benefit of the successors and assigns of the Trustee and the Debentureholders
and, in the event of any transfer or assignment of rights by any Debentureholder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the Debentures shall
automatically extend to and be vested in such transferee or assignee, all subject to the terms and
conditions of this Indenture.

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

          SECTION 11.05.   Modification. No modification, amendment or waiver of any provision
of this Article 11, nor the consent to any departure by Distribution therefrom, shall in any event
be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for which given. No
notice to or demand on Distribution in any case shall entitle Distribution to any other or further
notice or demand in the same, similar or other circumstances.

          SECTION 11.06.   Anti-Layering Covenant. Distribution shall not Incur, directly or
indirectly, or otherwise become liable for any Indebtedness which is subordinate or junior in right
of payment to any Senior Indebtedness unless such Indebtedness is Senior Subordinated Indebtedness
or is expressly subordinated in right of payment to Senior Subordinated Indebtedness. No
Indebtedness shall be deemed to be subordinated or junior in right of payment to any other
Indebtedness solely by virtue of being unsecured.

ARTICLE 12

Subordination of the Distribution Guarantee

          SECTION 12.01.   Agreement to Subordinate. Distribution agrees, and each
Debentureholder by accepting a Debenture agrees, that the obligations of Distribution hereunder are
subordinated in right of payment, to the extent and in the manner provided in this Article 12, to
the prior payment in full in cash or cash equivalents of all Senior Indebtedness of Distribution

- 79 -

 

and that the subordination is for the benefit of and enforceable by the holders of such Senior
Indebtedness of Distribution. The obligations hereunder with respect to Distribution shall in all
respects rank pari passu with all other Indebtedness of Distribution provided that the obligations
hereunder with respect to Distribution shall rank senior to all existing and future Subordinated
Obligations of Distribution; and only Indebtedness of Distribution that is Senior Indebtedness of
Distribution shall rank senior to the obligations of Distribution in accordance with the provisions
set forth herein.

          SECTION 12.02.   Liquidation, Dissolution, Bankruptcy. Upon any payment or
distribution of the assets of Distribution to creditors upon a total or partial liquidation or a
total or partial dissolution of Distribution or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to Distribution and its properties:

          (a) holders of Senior Indebtedness of Distribution shall be entitled to receive payment in
full in cash or cash equivalents of such Senior Indebtedness before the Debentureholders shall be
entitled to receive any payment pursuant to any Guaranteed Obligations from Distribution; and

          (b) until the Senior Indebtedness of Distribution is paid in full in cash or cash equivalents,
any payment or distribution to which Debentureholders would be entitled but for this Article 12
shall be made to holders of such Senior Indebtedness as their interests may appear.

          SECTION 12.03.   Default on Designated Senior Indebtedness of Distribution.
Distribution may not make any payment pursuant to any of the Guaranteed Obligations or repurchase,
redeem or otherwise retire any Debentures (collectively, “pay its Distribution Guarantee”) if (i)
any Designated Senior Indebtedness of Distribution is not paid in cash or cash equivalents when due
or (ii) any other default on Designated Senior Indebtedness of Distribution occurs and the maturity
of such Designated Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, (x) the default has been cured or waived and any such acceleration has been rescinded
or (y) such Designated Senior Indebtedness has been paid in full in cash or cash equivalents;
provided, however, that Distribution may pay its Distribution Guarantee without regard to the
foregoing if Distribution and the Trustee receive written notice approving such payment from the
Representative of such Designated Senior Indebtedness with respect to which either of the events
set forth in clause (i) or (ii) of this sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) or (ii) of the immediately
preceding sentence) with respect to any Designated Senior Indebtedness of Distribution pursuant to
which the maturity thereof may be accelerated immediately without further notice (except such
notice as may be required to effect such acceleration) or the expiration of any applicable grace
periods, Distribution may not pay its Distribution Guarantee for a period (a “Payment Blockage
Period”) commencing upon the receipt by the Trustee (with a copy to Distribution) of written notice
(a “Blockage Notice”) of such default from the Representative of such Designated Senior
Indebtedness of Distribution specifying an election to effect a Payment Blockage Period and ending
179 days thereafter (or earlier if such Payment Blockage Period is terminated (i) by written notice
to the Trustee (with a copy to Distribution) from the Person or Persons who gave such Blockage
Notice, (ii) by repayment in full in cash or cash equivalents of such Designated Senior
Indebtedness or (iii)

- 80 -

 

because the default giving rise to such Blockage Notice is no longer continuing).
Notwithstanding the provisions described in the immediately preceding sentence (but subject to the
provisions contained in the first sentence of this Section), unless the holders of such Designated
Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of
such Designated Senior Indebtedness, Distribution may resume to paying its Distribution Guarantee
after the end of such Payment Blockage Period, including any missed payments. Not more than one
Blockage Notice may be given with respect to Distribution in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior Indebtedness of
Distribution during such period; provided, however, that if any Blockage Notice
within such 360-day period is given by or on behalf of any holders of Designated Senior
Indebtedness of Distribution other than the Bank Indebtedness, the Representative of the Bank
Indebtedness may give another Blockage Notice within such period; provided further, however, that
in no event may the total number of days during which any Payment Blockage Period or Periods is in
effect exceed 179 days in the aggregate during any 360-consecutive day period. For purposes of
this Section, no default or event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a
subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness,
whether or not within a period of 360 consecutive days, unless such default or event of default
shall have been cured or waived for a period of not less than 90 consecutive days.

          SECTION 12.04.   Demand for Payment. If payment of the Debentures is accelerated
because of an Event of Default and a demand for payment is made on Distribution pursuant to Article
11, the Trustee shall promptly notify the holders of the Designated Senior Indebtedness of
Distribution (or the Representative of such holders) of such demand. If any Designated Senior
Indebtedness of Distribution is outstanding, Distribution may not pay its Distribution Guarantee
until five Business Days after such holders or the Representative of the holders of the Designated
Senior Indebtedness of Distribution receive notice of such demand and, thereafter, may pay its
Distribution Guarantee only if this Article 12 otherwise permits payment at that time.

          SECTION 12.05.   When Distribution Must Be Paid Over. If a payment or distribution is
made to Debentureholders that because of this Article 12 should not have been made to them, the
Debentureholders who receive the payment or distribution shall hold such payment or distribution in
trust for holders of the Senior Indebtedness of Distribution and pay it over to them as their
respective interests may appear.

          SECTION 12.06.   Subrogation. After all Senior Indebtedness of Distribution is paid
in full and until the Debentures are paid in full, Debentureholders shall be subrogated to the
rights of holders of such Senior Indebtedness of Distribution to receive distributions applicable
to Senior Indebtedness of Distribution. A distribution made under this Article 12 to holders of
Designated Senior Indebtedness of Distribution which otherwise would have been made to
Debentureholders is not, as between Distribution and Debentureholders, a payment by Distribution on
such Senior Indebtedness of Distribution.

- 81 -

 

          SECTION 12.07.   Relative Rights. This Article 12 defines the relative rights of
Debentureholders and holders of Senior Indebtedness of Distribution. Nothing in this Indenture
shall:

          (a) impair, as between Distribution and Debentureholders, the obligation of Distribution which
is absolute and unconditional, to make payments with respect to the Guaranteed Obligations to the
extent set forth in Article 11; or

          (b) prevent the Trustee or any Debentureholder from exercising its available remedies upon a
default by Distribution under its obligations with respect to the Guaranteed Obligations, subject
to the rights of holders of Senior Indebtedness of Distribution to receive distributions otherwise
payable to Debentureholders.

          SECTION 12.08.   Subordination May Not Be Impaired by Distribution. No right of any
holder of Senior Indebtedness of Distribution to enforce the subordination of the obligations of
Distribution hereunder shall be impaired by any act or failure to act by Distribution or by its
failure to comply with this Indenture.

          SECTION 12.09.   Rights of Trustee and Paying Agent. Notwithstanding Section 12.03,
the Trustee or the Paying Agent may continue to make payments on the Debentures and shall not be
charged with knowledge of the existence of facts that would prohibit the making of any such
payments unless, not less than three Business Days prior to the date of such payment, a Responsible
Officer of the Trustee receives notice satisfactory to it that payments may not be made under this
Article 12. Distribution, the Registrar or co-registrar, the Paying Agent, a Representative or a
holder of Senior Indebtedness of Distribution give the notice; provided, however,
that if an issue of Senior Indebtedness of Distribution has a Representative, only the
Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior Indebtedness of
Distribution with the same rights it would have if it were not Trustee. The Registrar and
co-registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled
to all the rights set forth in this Article 12 with respect to any Senior Indebtedness of
Distribution which may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness of Distribution; and nothing in Article 7 shall deprive the Trustee of any of its
rights as such holder. Nothing in this Article 12 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

          SECTION 12.10.   Distribution or Notice to Representative. Whenever a distribution is
to be made or a notice given to holders of Senior Indebtedness of Distribution, the distribution
may be made and the notice given to their Representative (if any).

          SECTION 12.11.   Article 12 Not to Prevent Events of Default or Limit Right to
Accelerate. The failure of Distribution to make a payment on any of its obligations by reason
of any provision in this Article 12 shall not be construed as preventing the occurrence of a
default by Distribution under such obligations. Nothing in this Article 12 shall have any effect
on the right of the Debentureholders or the Trustee to make a demand for payment on Distribution
pursuant to Article 11.

- 82 -

 

          SECTION 12.12.   Trustee Entitled to Rely. Upon any payment or distribution pursuant
to this Article 12, the Trustee and the Debentureholders shall be entitled to rely conclusively (i)
upon any order or decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 12.02 are pending, (ii) upon a certificate of the liquidating trustee
or agent or other Person making such payment or distribution to the Trustee or to the
Debentureholders or (iii) upon the Representatives for the holders of Senior Indebtedness of
Distribution for the purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of such Senior Indebtedness of Distribution and other Indebtedness of
Distribution, the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 12. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness of Distribution to participate in any payment or distribution
pursuant to this Article 12, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness of Distribution
held by such Person, the extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this Article 12, and, if
such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. The provisions of Sections
7.01 and 7.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 12.

          SECTION 12.13.   Trustee to Effectuate Subordination. Each Debentureholder by
accepting a Debenture authorizes and directs the Trustee on his or her behalf to take such action
as may be necessary or appropriate to acknowledge or effectuate the subordination between the
Debentureholders and the holders of Senior Indebtedness of Distribution as provided in this Article
12 and appoints the Trustee as attorney-in-fact for any and all such purposes.

          SECTION 12.14.   Trustee Not Fiduciary for Holders of Senior Indebtedness of
Distribution. The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness of Distribution and shall not be liable to any such holders if it shall
mistakenly pay over or distribute to Debentureholders or Distribution or any other Person, money or
assets to which any holders of Senior Indebtedness of Distribution shall be entitled by virtue of
this Article 12 or otherwise.

          SECTION 12.15.   Reliance by Holders of Senior Indebtedness of Distribution on
Subordination Provisions. Each Debentureholder by accepting a Debenture acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness of Distribution, whether such Senior
Indebtedness was created or acquired before or after the issuance of the Debentures, to acquire and
continue to hold, or to continue to hold, such Senior Indebtedness and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

Debentureholders of the required principal amount of Debentures have concurred in any direction,
waiver or consent, Debentures owned by the Company, Distribution or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company
or Distribution shall be disregarded and deemed not to be outstanding, except that, for the purpose
of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Debentures which a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded. Subject to the foregoing, only Debentures outstanding at the time shall
be considered in any such determination.

[FORM OF REVERSE SIDE OF DEBENTURE]

6.0% Convertible Senior Debenture due 2029

1. Interest

          (a) WESCO INTERNATIONAL, INC., a Delaware corporation (such corporation, and its successors
and assigns under the Indenture hereinafter referred to, being herein called the “Company”),
promises to pay interest on the principal amount of this Debenture at the rate per annum shown
above. The Company will pay interest semiannually on March 15 and September 15 of each year,
commencing on March 15, 2010. Interest on the Debentures will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from August 27, 2009. Interest will
be computed on the basis of a 360-day year of twelve 30-day months. If a payment date is not a
Business Day, payment will be made on the next succeeding Business Day, and no additional interest
will accrue in respect of such payment by virtue of the payment being made on such later date.

          (b) Contingent Interest. Beginning with the six-month interest period commencing
September 15, 2016, the Company will pay interest (“Contingent Interest”) during any six-month
interest period if the Trading Price of the Debentures for each of the five Trading Days ending on
the second Trading Day immediately preceding the first day of the applicable six-month interest
period equals or exceeds 120% of the principal amount of the Debentures. During any six-month
interest period when Contingent Interest is payable, the Contingent Interest payable on each $1,000
principal amount of Debentures shall equal 0.25% of the average Trading Price of $1,000 principal
amount of Debentures during the five Trading Days ending on the second Trading Day immediately
preceding the first day of the applicable six-month interest period used to determine whether
Contingent Interest must be paid.

          (c) Additional Interest. The Holder of this Debenture is entitled to receive
additional interest (“Additional Interest”) in connection with an Event of Default relating to the
Company’s failure to comply with its reporting obligations in Section 4.03 of the Indenture as and
to the extent provided in the Indenture.

          (d) Except as otherwise specifically set forth, all references herein to “interest” include
defaulted interest, Contingent Interest and Additional Interest, if any.

2. Method of Payment

          The Company will pay interest on the Debentures (except defaulted interest) to the Persons who
are registered Holders of Debentures at the close of business on the March 1 and September 1 next
preceding the interest payment date even if Debentures are canceled after the record date and on or
before the interest payment date, except as otherwise provided in the Indenture. Holders must
surrender Debentures to a Paying Agent to collect principal payments. The Company will pay
principal and interest in money of the United States of America that at the time of payment is
legal tender for payment of public and private debts. The Company shall pay interest (i) on any
Global Debentures by wire transfer of immediately available funds to the account of the Depositary
or its nominee, (ii) on any Debentures in certificated form having a principal amount of less than
$2,000,000, by check mailed to the address of the Person entitled

 

 

thereto as it appears in the Register, provided, however, that at maturity
interest will be payable at the office of the Company maintained by the Company for such purposes
in the Borough of Manhattan, The City of New York, which shall initially be an office or agency of
the Trustee (as defined below) and (iii) on any Debentures in certificated form having a principal
amount of $2,000,000 or more, by wire transfer in immediately available funds at the election of
the Holder of such Debentures duly delivered to the Trustee at least five Business Days prior to
the relevant interest payment date, provided, however, that at maturity interest
will be payable at the office of the Company maintained by the Company for such purposes in the
Borough of Manhattan, The City of New York, which shall initially be an office or agency of the
Trustee.

3. Paying Agent and Registrar

          Initially, The Bank of New York Mellon, a New York banking corporation (the “Trustee”), will
act as Paying Agent, Registrar and conversion agent. The Company may appoint and change any Paying
Agent, Registrar or co-registrar or conversion agent upon written notice to such Paying Agent,
Registrar or conversion agent and to the Trustee. The Company or any of its domestically

4. Indenture

          The Company issued the Debentures under an Indenture dated as of August 27, 2009 (the
“Indenture”), among the Company, WESCO Distribution, Inc. (“Distribution”) and the Trustee. The
terms of the Debentures include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on
the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have
the meanings ascribed thereto in the Indenture. The Debentures are subject to all such terms, and
Debentureholders are referred to the Indenture and the TIA for a statement of those terms.

          The Debentures are senior unsecured obligations of the Company. This Debenture is one of the
Debentures referred to in the Indenture issued in an aggregate principal amount of $345.0 million.
The Indenture also imposes limitations on the ability of each of the Company and Distribution to
consolidate or merge with or into any other Person or convey, transfer or lease all or
substantially all of its assets.

          To guarantee the due and punctual payment of the principal, premium, if any, and interest on
the Debentures and all other amounts payable by the Company under the Indenture and the Debentures
when and as the same shall be due and payable, whether at maturity, by acceleration upon
conversion, redemption, repurchase or otherwise, according to the terms of the Debentures and the
Indenture, Distribution has unconditionally guaranteed the Guaranteed Obligations on a senior
subordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

          At any time on or after September 15, 2016, the Debentures will be redeemable at the option of
the Company, in whole or in part, on not less than 30 calendar days’ nor more than

- 2 -

 

60 calendar days’ prior notice, at a redemption price equal to 100% of the principal amount of
the Debentures being redeemed, plus accrued and unpaid interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant
interest payment date).

          At any time on or prior to September 15, 2010, if a Tax Triggering Event has occurred, the
Debentures will be redeemable at the option of the Company, in whole or in part, on not less than
30 calendar days’ nor more than 60 calendar days’ prior notice, at the redemption price equal to
101.5% of the principal amount thereof plus if the Conversion Value as of the redemption date of
the Debentures being redeemed exceeds their Initial Conversion Value, 95% of the amount determined
by subtracting the Initial Conversion Value of such Debentures from their Conversion Value as of
the redemption date, plus accrued and unpaid interest to the redemption date (subject to the right
of Holders of record on the relevant record date to receive interest due on the relevant interest
payment date).

6. Sinking Fund

          The Debentures are not subject to any sinking fund.

7. Notice of Redemption

          Notice of redemption will be mailed by first-class mail at least 30 calendar days but not more
than 60 calendar days before the redemption date to each Holder of Debentures to be redeemed at his
or her registered address; provided that such notice must be given at least 24 Scheduled
Trading Days prior to the redemption date. Debentures in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption
price of and accrued interest on all Debentures (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue on such Debentures
(or such portions thereof) called for redemption.

8. Repurchase of Debentures at the Option of Debentureholders

          If a Fundamental Change occurs at any time prior to maturity of the Debentures, this Debenture
will be subject to a repurchase, at the option of the Holder, on a Fundamental Change Repurchase
Date, specified by the Company, that is not less than 20 calendar days nor more than 35 calendar
days after notice thereof, at a repurchase price equal to 100% of the principal amount hereof,
together with accrued and unpaid interest on this Debenture to, but excluding, the Fundamental
Change Repurchase Date; provided that if such Fundamental Change Repurchase Date falls
after a record date and on or prior the corresponding interest payment date, the accrued and unpaid
interest shall be payable to the Holder of record of this Debenture on the preceding March 1 or
September 1, as the case may be. The Debentures submitted for repurchase must be $1,000 in
principal amount or a whole multiple of $1,000 thereof. The Company shall mail to all Holders of
record of the Debentures (and to beneficial owners as required by applicable law) a notice of the
occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or
before the fifth calendar day after the occurrence of such Fundamental Change. For Debentures to
be so repurchased at the option of

- 3 -

 

the Holder, the Holder must deliver to the Paying Agent in accordance with the terms of the
Indenture, the Repurchase Notice containing the information specified by the Indenture, together
with such Debentures, duly endorsed for transfer, or (if the Debentures are Global Debentures)
book-entry transfer of the Debentures, prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Fundamental Change Repurchase Date. The repurchase price must be paid in
cash.

          Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a
written notice of withdrawal at any time prior to 5:00 p.m., New York City time, on the Business
Day immediately preceding the Fundamental Change Repurchase Date, as provided in the Indenture.

          If cash sufficient to pay the repurchase price of, and accrued and unpaid interest, if any, on
all Debentures or portions thereof to be repurchased as of the Fundamental Change Repurchase Date
is deposited with the Paying Agent, on the Fundamental Change Repurchase Date, then such Debentures
will cease to be outstanding and interest will cease to accrue on such Debentures immediately
thereafter, and the Holder thereof shall have no other rights as such other than the right to
receive the repurchase price upon surrender of such Debentures.

9. Conversion

          Upon the occurrence of certain events specified in the Indenture and in compliance with the
provisions of the Indenture, on or prior to the close of business on the Trading Day immediately
preceding September 15, 2029, the Holder hereof has the right, at its option, to convert each
$1,000 principal amount of this Debenture into cash and, if applicable, Common Stock based on a
Conversion Rate of 34.6433 shares of Common Stock per $1,000 principal amount of Debentures (a
conversion price of approximately $28.8656 per share), as the same may be adjusted pursuant to the
terms of the Indenture, as such shares shall be constituted at the date of conversion, upon
surrender of this Debenture (if in certificated form) with the form entitled “Conversion Notice” on
the reverse hereof duly completed and manually signed, to the Company at the office or agency of
the Company maintained for that purpose in The City of New York in accordance with the terms of the
Indenture, or at the option of such Holder, the Corporate Trust Office, together with any funds
required pursuant to the terms of the Indenture, and, unless any shares issuable on conversion are
to be issued in the same name as this Debenture, duly endorsed by, or accompanied by instruments of
transfer in form satisfactory to the Company duly executed by, the Holder or by such Holder’s duly
authorized attorney. The Company will notify the Holder thereof of any event triggering the right
to convert the Debentures as specified above in accordance with the Indenture. In order to
exercise the conversion right with respect to any interest in a Global Debenture, the Holder must
complete the appropriate instruction form pursuant to the Depositary’s book-entry conversion
program, deliver by book-entry delivery an interest in such Global Debenture, furnish appropriate
endorsements and transfer documents if required by the Company or the Trustee or conversion agent,
and pay the funds, if any, required pursuant to the terms of the Indenture. As specified in the
Indenture, upon conversion, the Company will pay cash and shares of Common Stock, if any, based on
a Daily Conversion Value calculated on a proportionate basis for each day of the 20 Trading-Day
Cash Settlement Averaging Period.

- 4 -

 

          If and only to the extent Holders elect to convert the Debentures in connection with a
Non-Stock Change of Control (as defined in the Indenture), the Company will increase the Conversion
Rate applicable to such converting Debentures subject to the limitations set forth in the
Indenture.

          No adjustment in respect of interest on any Debentures converted or dividends on any shares
issued upon conversion of such Debentures will be made upon any conversion except as set forth in
the next sentence. If this Debenture (or portion hereof) is surrendered for conversion during the
period from the 5:00 p.m., New York City time, on any applicable Record Date for the payment of
interest to 5:00 p.m., New York City time, on the Business Day preceding the corresponding interest
payment date, this Debenture (or portion hereof being converted) must be accompanied by payment, in
immediately available funds or other funds acceptable to the Company, of an amount equal to the
interest otherwise payable on such interest payment date on the principal amount being converted;
provided that no such payment shall be required (1) if a Holder converts its Debentures in
connection with a redemption and the Company has specified a redemption date that is after a Record
Date and on or prior to the next interest payment date, (2) if the Holder surrenders this Debenture
for conversion in connection with a Fundamental Change and the Company has specified a Fundamental
Change Repurchase Date that is after a Record Date and on or prior to the corresponding interest
payment date or (3) to the extent of any overdue interest, if any, existing at the time of
conversion with respect to this Debenture.

          No fractional shares will be issued upon any conversion of Debentures, but an adjustment and
payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share
which would otherwise be issuable upon the surrender of any Debentures or Debentures for
conversion.

          A Debenture in respect of which a Holder is exercising its right to require repurchase may be
converted only if such Holder validly withdraws its election to exercise such right to require
repurchase in accordance with the terms of the Indenture.

10. Denominations, Transfer, Exchange

          The Debentures are in registered form without coupons in denominations of $2,000 principal
amount and integral multiples of $1,000 in excess thereof. A Debentureholder may transfer or
exchange Debentures in accordance with the Indenture. Upon any transfer or exchange, the Registrar
and the Trustee may require a Debentureholder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or permitted by the
Indenture. The Registrar need not issue, register the transfer of, or exchange any Debentures
during the period of 15 days before the mailing of the notice of redemption, or register the
transfer of or exchange any Debentures so selected for redemption, in whole or in part, except the
unredeemed portion of any Debentures being redeemed in part.

11. Persons Deemed Owners

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

- 5 -

 

12. Unclaimed Money

          Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Company upon written request any money held by them for the payment of principal or interest
and any shares of Common Stock or other property due in respect of converted Debentures that
remains unclaimed for two years, and, thereafter, Debentureholders entitled to the money and/or
securities must look to the Company for payment as general creditors.

13. Amendment, Waiver

          Subject to certain exceptions set forth in the Indenture, (i) the Indenture (including the
Distribution Guarantee contained therein) or the Debentures may be amended without prior notice to
any Debentureholder but with the written consent of the Holders of a majority in aggregate
principal amount of the outstanding Debentures (including consents obtained in connection with a
tender offer or exchange offer for the Debentures) and (ii) any default or noncompliance with
certain provisions may be waived with the written consent of the Holders of a majority in principal
amount of the outstanding Debentures. Subject to certain exceptions set forth in the Indenture,
without the consent of any Holder of Debentures, the Company, Distribution and the Trustee may
amend the Indenture (including the Distribution Guarantee contained therein) or the Debentures (i)
to cure any ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5 or Section
11.03 of the Indenture; (iii) to provide for uncertificated Debentures in addition to or in place
of certificated Debentures; provided, however, that the uncertificated Debentures
are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that
the uncertificated Debentures are described in 163(f)(2)(B) of the Code; (iv) to make any change in
Article 12 of the Indenture that would limit or terminate the benefits available to any holder of
Senior Indebtedness (or any Representatives therefor) under Article 12 of the Indenture; (v) to add
additional Guarantees with respect to the Debentures or to secure the Debentures; (vi) to add
additional covenants of the Company or Distribution for the benefit of the Debentureholders or to
surrender rights and powers conferred on the Company or Distribution; (vii) to make any change that
does not adversely affect the rights of any Debentureholder, subject to the provisions of the
Indenture; (viii) to provide for a successor Trustee; (ix) to conform the terms of the Indenture
(including the Distribution Guarantee contained therein) or the Debentures with the descriptions
set forth in the “Description of the 2029 Debentures” section of the Prospectus to the extent that
such description in the “Description of the 2029 Debentures” section of the Prospectus was intended
to be a verbatim recitation of a provision of the Indenture (including the Distribution Guarantee
contained therein) or the Debentures or (x) to comply with any requirements of the SEC in
connection with qualifying, or maintaining the qualification of, the Indenture under the TIA.

14. Defaults and Remedies

          If an Event of Default occurs (other than an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the outstanding Debentures may declare the principal
of, premium, if any, and accrued but unpaid interest on all the Debentures to be due and payable.
If an Event of Default relating to certain events of bankruptcy, insolvency

- 6 -

 

or reorganization of the Company occurs, the principal of, premium, if any, and interest on
all the Debentures will become immediately due and payable without any declaration or other act on
the part of the Trustee or any Debentureholders. Under certain circumstances, the Holders of a
majority in principal amount of the outstanding Debentures may rescind any such acceleration with
respect to the Debentures and its consequences.

          Notwithstanding the foregoing, the sole remedy for an Event of Default relating to the
Company’s failure to comply with its reporting obligations in the Indenture, will, at the option of
the Company, for the first 365 days after the occurrence of such Event of Default, consist
exclusively of the right to receive Additional Interest on the Debentures at an annual rate equal
to 0.50% of the principal amount of the Debentures.

          If an Event of Default occurs and is continuing, the Trustee will be under no obligation to
exercise any of the rights or powers under the Indenture at the request or direction of any of the
Debentureholders unless such Debentureholders have offered to the Trustee reasonable indemnity or
security against any loss, liability or expense. Subject to certain exceptions, no Debentureholder
may pursue any remedy with respect to the Indenture or the Debentures unless (i) such
Debentureholder has previously given the Trustee notice that an Event of Default is continuing,
(ii) Holders of at least 25% in principal amount of the outstanding Debentures have requested the
Trustee in writing to pursue the remedy, (iii) such Debentureholders have offered the Trustee
security or indemnity satisfactory to the Trustee against any loss, liability or expense, (iv) the
Trustee has not complied with such request within 60 days after the receipt of the request and the
offer of security or indemnity and (v) the Holders of a majority in principal amount of the
outstanding Debentures have not given the Trustee a direction inconsistent with such request within
such 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount
of the outstanding Debentures are given the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that
conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the
rights of any other Debentureholder or that would involve the Trustee in personal liability. Prior
to taking any action under the Indenture, the Trustee will be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused by taking or not
taking such action.

          No reference herein to the Indenture and no provision of this Debenture or of the Indenture
shall impair, as among the Company and the Holder of the Debentures, the obligation of the Company,
which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this
Debenture at the place, at the respective times, at the rate and in the coin or currency herein and
in the Indenture prescribed, or to deliver Common Stock (including any Additional Shares), or cash
in lieu thereof, or a combination of the foregoing, as applicable upon the conversion of any
Debentures pursuant to the terms of this Indenture.

15. Tax Treatment

          The Company agrees, and by acceptance of beneficial ownership interest in the Debentures each
Holder of the Debentures will be deemed to have agreed, for U.S. federal income tax purposes (1) to
treat the Debentures as indebtedness that is subject to Treas. Reg.

- 7 -

 

Sec. 1.1275-4 (the “Contingent Payment Regulations”) and, for purposes of the Contingent
Payment Regulations, to treat the cash and the fair market value of any stock beneficially received
by a Holder upon any conversion of the Debentures as a contingent payment and (2) to be bound by
the Company’s determination of the “comparable yield” and “projected payment schedule,” within the
meaning of the Contingent Payment Regulations, with respect to the Debentures. A Holder may obtain
the issue price, amount of original issue discount, issue date, yield to maturity, comparable yield
and projected payment schedule for the Debentures by submitting a written request for such
information to the Company at the following address: Wesco International, Inc., 225 West Station
Square Drive, Suite 700, Pittsburgh, PA 15219, Attention: Investor Relations Department.

16. Trustee Dealings with the Company

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

17. No Recourse Against Others

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

18. Authentication

          This Debenture shall not be valid until an authorized signatory of the Trustee (or an
authenticating agent) manually signs the certificate of authentication on the other side of this
Debenture.

19. Abbreviations

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

20. GOVERNING LAW

          THIS DEBENTURE AND THE INDENTURE (INCLUDING THE GUARANTEE OF DISTRIBUTION) SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

- 8 -

 

21. CUSIP and ISIN Numbers

          Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Debentures and has
directed the Trustee to use CUSIP and ISIN numbers in notices of redemption as a convenience to
Debentureholders. No representation is made as to the accuracy of such numbers either as printed
on the Debentures or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

          The Company will furnish to any Holder of Debentures upon written request and without charge
to the Holder a copy of the Indenture which has in it the text of this Debenture.
