within a reasonable period of time. The Trustee is hereby appointed the “Note Registrar” for the
purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint
one or more co-Note Registrars in accordance with Section 4.02.

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

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

     All Notes presented or surrendered for registration of transfer or for exchange, repurchase or
conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note
Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer
in form satisfactory to the Company and duly executed, by the Holder thereof or its
attorney-in-fact duly authorized in writing.

12

 

     No service charge shall be charged to the Holder for any exchange or registration of transfer
of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any
tax or other similar governmental charge required by law or permitted pursuant to Section 14.02(f).

     None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to
exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any
Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with
Article 15 or (iii) any Notes selected for redemption in accordance with Article 16.

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

          (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, all Notes shall be represented by one or more Notes in global form
(each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary.
The transfer and exchange of beneficial interests in a Global Note that does not involve the
issuance of a Physical Note, shall be effected through the Depositary (but not the Trustee or the
Custodian) in accordance with this Indenture (including the restrictions on transfer set forth
herein) and the procedures of the Depositary therefor.

          (c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set
forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes
and required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c)
(including the legend set forth below), and the Holder of each such Restricted Security, by such
Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in
this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any sale, pledge,
transfer or other disposition whatsoever of any Restricted Security.

     Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date
that is one year after the last date of original issuance of the Notes, or such shorter period of
time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2)
such later date, if any, as may be required by applicable law, any certificate evidencing such Note
(and all securities issued in exchange therefor or substitution thereof, other than Common Stock,
if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.05(d), if
applicable) shall bear a legend in substantially the following form (unless such Notes have been
transferred pursuant to a registration statement that has become or been declared effective under
the Securities Act and that continues to be effective at the time of such transfer, or sold
pursuant to the exemption from registration provided by Rule 144 or any similar provision then in
force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice
thereof to the Trustee):

THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION
OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NONE OF
THIS SECURITY, THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS
SECURITY OR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD,
ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE
ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR
NOT SUBJECT TO, REGISTRATION.

THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT
(A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER
THE SECURITIES ACT)

13

 

(B) IT IS A NON-U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION
WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT AND IN
ACCORDANCE WITH THE LAWS APPLICABLE TO SUCH PURCHASER IN THE JURISDICTION
IN WHICH SUCH PURCHASE IS MADE, OR (C) IT IS AN “ACCREDITED INVESTOR”
WITHIN THE MEANING OF RULE 501 UNDER THE SECURITIES ACT AND (2) AGREES TO
OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE EXPIRATION OF
THE APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET
FORTH IN RULE 144 UNDER THE SECURITIES ACT, ONLY (A) TO ALTRA HOLDINGS,
INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE
SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT
REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE
144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE
ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT
THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS
AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN
THE MEANING OF REGULATION S UNDER THE SECURITIES ACT AND IN ACCORDANCE WITH
THE LAWS APPLICABLE TO IT IN THE JURISDICTION IN WHICH SUCH PURCHASE IS
MADE, (D) TO AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF RULE 501 UNDER
THE SECURITIES ACT THAT IS ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT, OR
FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL ACCREDITED INVESTOR, FOR
INVESTMENT PURPOSES AND NOT WITH A VIEW TO, OR FOR OFFER OR SALE IN
CONNECTION WITH, ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, (E)
PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE
UNDER THE SECURITIES ACT, OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE
COMPANY’S AND THE TRUSTEE’S, OR REGISTRAR’S, AS APPLICABLE, RIGHT PRIOR TO
ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (C), (D) OR (F) TO
REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER
INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING
CASES, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF
THIS SECURITY IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE
OR REGISTRAR. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER
AFTER THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH RESPECT TO
RESTRICTED SECURITIES SET FORTH IN RULE 144 UNDER THE SECURITIES ACT.

     No transfer of any Note prior to the Resale Restriction Termination Date will be
registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer
has been checked.

     Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of
such Note for exchange to the Note Registrar in accordance with the provisions of this Section
2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.05(c). The

14

 

Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction
Termination Date and promptly after a registration statement, if any, with respect to the Notes or
any Common Stock issued upon conversion of the Notes has been declared effective under the
Securities Act.

     Notwithstanding any other provisions of this Indenture (other than the provisions set forth in
this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global
Note in certificated form made upon request of a member of, or a participant in, the Depositary
(for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on
behalf of the Depositary in accordance with customary procedures of the Depositary and in
compliance with this Section 2.05(c).

     The Depositary shall be a clearing agency registered under the Exchange Act. The Company
initially appoints The Depository Trust Company to act as Depositary with respect to each Global
Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of
Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede
& Co.

     If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or
unable to continue as depositary for the Global Notes and a successor depositary is not appointed
within 90 calendar days; (ii) the Depositary ceases to be registered as a clearing agency under the
Exchange Act and a successor depositary is not appointed within 90 calendar days; (iii) the
Company, at its option, notifies the Trustee that it elects to cause the issuance of Physical
Notes, subject to the Depositary’s procedures; or (iv) an Event of Default in respect of the Notes
has occurred and is continuing and the Trustee has received a request from the Depositary, the
Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order
for the authentication and delivery of Notes, will authenticate and deliver Physical Notes to each
beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal
to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of
the Global Note to the Trustee such Global Note shall be canceled.

     Notwithstanding the foregoing provisions, beneficial interests in a Global Note may be
exchanged for Physical Notes in accordance with the procedures of the Depositary.

     Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.05(c) shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical
Notes to the Persons in whose names such Physical Notes are so registered.

     At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance
with standing procedures and existing instructions between the Depositary and the Custodian. At
any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes
therefor or any Physical Note is exchanged or transferred for part of such Global Note, the
principal amount of such Global Note shall, in accordance with the standing procedures and
instructions existing between the Depositary and the Custodian, be appropriately reduced or
increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee
or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

     None of the Company, the Trustee or any agent of the Company or the Trustee shall have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

          (d) Until the Resale Restriction Termination Date, any stock certificate representing Common
Stock issued upon conversion of such Note shall bear a legend in substantially the following form
(unless the Note or such Common Stock has been transferred pursuant to a registration statement
that has become or been declared effective under the Securities Act and that continues to be
effective at the time of such transfer, or pursuant to the exemption from registration provided by
Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has
been issued upon conversion of Notes that have been transferred pursuant to a

15

 

registration statement that has become or been declared effective under the Securities Act and
that continues to be effective at the time of such transfer, or pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act,
or unless otherwise agreed by the Company with written notice thereof to the Trustee and any
transfer agent for the Common Stock):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS.
NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE
REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION
IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT
(A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER
THE SECURITIES ACT) (B) IT IS A NON-U.S. PERSON AND IS ACQUIRING THIS
SECURITY IN AN OFFSHORE TRANSACTION WITHIN THE MEANING OF REGULATION S
UNDER THE SECURITIES ACT AND IN ACCORDANCE WITH THE LAWS APPLICABLE TO SUCH
PURCHASER IN THE JURISDICTION IN WHICH SUCH PURCHASE IS MADE, OR (C) IT IS
AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF RULE 501 UNDER THE
SECURITIES ACT AND (2) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH
SECURITY, PRIOR TO THE EXPIRATION OF THE APPLICABLE HOLDING PERIOD WITH
RESPECT TO RESTRICTED SECURITIES SET FORTH IN RULE 144 UNDER THE SECURITIES
ACT, ONLY (A) TO ALTRA HOLDINGS, INC. (THE “COMPANY”) OR ANY SUBSIDIARY
THEREOF, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT
TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED
INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT
PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING
MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS AND SALES TO NON-U.S.
PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF
REGULATION S UNDER THE SECURITIES ACT AND IN ACCORDANCE WITH THE LAWS
APPLICABLE TO IT IN THE JURISDICTION IN WHICH SUCH PURCHASE IS MADE, (D) TO
AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF RULE 501 UNDER THE
SECURITIES ACT THAT IS ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT, OR FOR
THE ACCOUNT OF SUCH AN INSTITUTIONAL ACCREDITED INVESTOR, FOR INVESTMENT
PURPOSES AND NOT WITH A VIEW TO, OR FOR OFFER OR SALE IN CONNECTION WITH,
ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, (E) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE
SECURITIES ACT, OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S
AND THE TRUSTEE’S, OR REGISTRAR’S, AS APPLICABLE, RIGHT PRIOR TO ANY SUCH
OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (C), (D) OR (F) TO REQUIRE THE

16

 

DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO
EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, A CERTIFICATE OF TRANSFER
IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY IS COMPLETED AND
DELIVERED BY THE TRANSFEROR TO THE TRUSTEE OR REGISTRAR. THIS LEGEND WILL
BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE EXPIRATION OF THE
APPLICABLE HOLDING PERIOD WITH RESPECT TO RESTRICTED SECURITIES SET FORTH
IN RULE 144 UNDER THE SECURITIES ACT.

     Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon surrender of the certificates representing such shares of
Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of
Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

          (e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is
repurchased or owned by the Company or any Affiliate thereof may not be resold by the Company or
such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from
the registration requirements of the Securities Act in a transaction that results in such Notes or
Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule
144 under the Securities Act).

          (f) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security (including any transfers between or
among Participants or beneficial owners of interests in any Global Note) 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 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its
written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate
and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen. In every case the applicant for a substituted Note 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 from any loss, liability, cost or expense caused
by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof.

     The Trustee or such authenticating agent may authenticate any such substituted Note and
deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if
applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the
Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Note that has matured or is about to mature or has been
surrendered for required repurchase or is about to be converted in accordance with Article 14 shall
become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead
of issuing a substitute Note, 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 Note), 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 connected with such substitution, and, in every case of destruction, loss or theft, evidence
satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent
evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.

17

 

     Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the
fact that any Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or
conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment or conversion of negotiable instruments or
other securities without their surrender.

     Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may
execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written
request of the Company, authenticate and deliver temporary Notes (printed or lithographed).
Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of
the Physical Notes but with such omissions, insertions and variations as may be appropriate for
temporary Notes, all as may be determined by the Company. Every such temporary Note 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 Physical Notes.
Without unreasonable delay, the Company will execute and deliver to the Trustee or such
authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary
Notes (other than any Global Note) 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 deliver in exchange for such temporary Notes an equal aggregate
principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense
and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits and subject to the same limitations under this Indenture as Physical
Notes authenticated and delivered hereunder.

     Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes
surrendered for the purpose of payment, repurchase, redemption, registration of transfer or
exchange or conversion, if surrendered to any Person other than the Trustee (including any of the
Company’s Agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation.
All Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall be
authenticated in exchange thereof except as expressly permitted by any of the provisions of this
Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures
and, after such disposition, shall deliver a certificate of such disposition to the Company, at the
Company’s written request in a Company Order. If the Company shall acquire any of the Notes, such
acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness
represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

     Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to
Holders as a convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on
such notice and that reliance may be placed only on the other identification numbers printed on the
Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP”
numbers.

     Section 2.10. Additional Notes; Repurchases. The Company may, without the consent of the
Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes
hereunder with the same terms and with the same CUSIP number as the Notes initially issued
hereunder in an unlimited aggregate principal amount; provided that such additional Notes must be
fungible with the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to
the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company
Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion
of Counsel to cover such matters, in addition to those required by Section 18.05, as the Trustee
shall reasonably request. In addition, the Company may, to the extent permitted by law, directly
or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes
in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or
public tender or exchange offer or through counterparties to private agreements, including by
cash-settled swaps or other derivatives. The Company shall cause any Notes so purchased to be
surrendered to the Trustee for cancellation in accordance with Section 2.08. For the avoidance of

18

 

doubt, for the purpose of the foregoing, Notes purchased pursuant to cash-settled swaps or
other derivatives shall not be considered “purchased.”

ARTICLE 3

Satisfaction and Discharge

     Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company
contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the
expense of the Company, shall execute instruments as reasonably requested by the Company
acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore
authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money
has theretofore been deposited in trust or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d))
have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the
Trustee or delivered to Holders, as applicable, after the Notes have become due and payable,
whether at the Maturity Date, on any Redemption Date, Option Repurchase Date or Fundamental Change
Repurchase Date, or upon conversion or otherwise, cash, shares of Common Stock, or a combination
thereof, solely to satisfy the Company’s Conversion Obligation, or government obligations,
sufficient to pay all of the outstanding Notes and all other sums due and payable under this
Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the
satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under
Section 7.06 shall survive.

ARTICLE 4

Particular Covenants of the Company

     Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it
will cause to be paid the principal (including the Option Repurchase Price or the Fundamental
Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes
at the places, at the respective times and in the manner provided herein and in the Notes.

     Section 4.02. Maintenance of Office or Agency. The Company will maintain an office or agency
where the Notes may be surrendered for registration of transfer or exchange or for presentation for
payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. 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 as co-Note Registrars one or more other
offices or agencies where the Notes 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. The terms “Paying Agent” and “Conversion Agent” include any such
additional or other offices or agencies, as applicable.

     The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar,
Custodian and Conversion Agent and the Corporate Trust Office shall be considered as one such
office or agency of the Company for each of the aforesaid purposes.

     Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided
in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

19

 

     Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent
other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions
of this Section 4.04:

          (i) that it will hold all sums held by it as such agent for the payment of the
principal (including the Option Repurchase Price or the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes
in trust for the benefit of the Holders of the Notes;

          (ii) that it will give the Trustee prompt notice of any failure by the Company
to make any payment of the principal (including the Option Repurchase Price or the
Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid
interest on, the Notes when the same shall be due and payable; and

          (iii) that at any time during the continuance of an Event of Default, upon
request of the Trustee, it will forthwith pay to the Trustee all sums so held in
trust.

     The Company shall, on or before each due date of the principal (including the Option
Repurchase Price or the Fundamental Change Repurchase Price, if applicable) of, or accrued and
unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal
(including the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable)
or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of any failure to take such action; provided that if such deposit is
made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York
City time, on such date.

          (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of
the principal (including the Option Repurchase Price or the Fundamental Change Repurchase Price, if
applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in
trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including
the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable) and accrued
and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure
to take such action and of any failure by the Company to make any payment of the principal
(including the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable)
of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

          (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the
Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be
held by the Trustee upon the trusts herein contained and upon such payment or delivery by the
Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from
all further liability but only with respect to such sums or amounts.

          (d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal (including the Option
Repurchase Price or the Fundamental Change Repurchase Price, if applicable) of, and accrued and
unpaid interest on, any Note and remaining unclaimed for two years after such principal (including
the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable) or interest
has become due and payable shall be paid to the Company on request of the Company contained in an
Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money and shares of Common Stock, and all liability of the Company as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to be published once,
in a newspaper published in the English language, customarily published on each Business Day and of
general circulation in The City of New York, notice that such money and shares of Common Stock
remains unclaimed and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money and shares of Common Stock
then remaining will be repaid or delivered to the Company.

     Section 4.05. Existence. Subject to Article 11, the Company will do or cause to be done all
things necessary to preserve and keep in full force and affect its corporate existence.

     Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the
Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as
any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such
time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, promptly provide to the Trustee and shall, upon written request, provide to any Holder,
beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon
conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant
to Rule 144A under the Securities Act. The Company shall take such further action as any Holder or
beneficial owner of such Notes or such Common Stock may reasonably request to the extent required
from time to time to enable such Holder or beneficial owner to sell such Notes or shares of Common
Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time
to time.

          (b) The Company shall file with the Trustee within 45 calendar days after the same are
required to be filed with the Commission, copies of any documents or reports that the Company is
required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or Section
314(a)(1) of the Trust Indenture Act (giving effect to any grace period provided by Rule 12b-25
under the Exchange Act). Any such document or report that the Company files with the Commission
via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this
Section 4.06(b) at the time such documents are filed via the EDGAR system.

          (c) Delivery of the reports and documents described in subsection (b) above 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 conclusively rely on an Officers’ Certificate). The Trustee is under no
duty to examine such reports, information or documents to ensure compliance with the provisions of
this Indenture or to ascertain the correctness or otherwise of the information or the statements
contained therein. The Trustee shall not be obligated to monitor or confirm, on a continuing basis
or otherwise, the Company’s or any other Person’s compliance with the covenants described above or
with respect to any reports or other documents filed under this Agreement.

          (d) If, at any time during the six-month period beginning on, and including, the date that is
six months after the last date of original issuance of the Notes, the Company fails to timely file
any document or report that it is required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods
thereunder and other than reports on Form 8-K) and the Company has not cured such failure to timely
file within 14 days after such failure, or the Notes are not otherwise freely tradable by Holders
other than the Company’s Affiliates (as a result of restrictions pursuant to U.S. securities law or
the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes.
Such Additional Interest shall accrue on the Notes at the rate of 0.25% per annum of the principal
amount of the Notes outstanding for each day during the first 90-day period beginning on, and
including, the date on which the Company’s failure to file has occurred and is continuing, and
0.50% per annum of the principal amount of Notes outstanding for each day after the 90th day, in
each case ending on the date that is one year after the last original issuance date of such Notes.
As used in this Section 4.06(d), documents or reports that the Company is required to “file” with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or
reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the
Exchange Act.

          (e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c)
has not been removed or the Notes are not otherwise freely tradable by Holders other than the
Company’s Affiliates (without restrictions pursuant to U.S. securities law or the terms of this
Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes,
the Company shall pay Additional Interest on the Notes at a rate equal to 0.25% per annum of the
principal amount of Notes outstanding during the first 90 days of such period, and 0.50% per annum
of the principal amount of the Notes outstanding for each day after the 90th day, until the
restrictive legend on the Notes has been removed in accordance with Section 2.05(c) and the Notes
are freely

21

 

tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S.
securities law or the terms of this Indenture or the Notes).

          (f) Additional Interest will be payable in arrears on each Interest Payment Date following
accrual in the same manner as ordinary interest on the Notes.

          (g) The Additional Interest that is payable in accordance with Section 4.06(d) or Section
4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as
a result of the Company’s election pursuant to Section 6.03.

          (h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section
4.06(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating
(i) the amount of such Additional Interest that is payable and (ii) the date on which such
Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at
the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such
Additional Interest is payable. If the Company has paid Additional Interest directly to the
Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting
forth the particulars of such payment.

     Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or other law that would
prohibit or forgive the Company from paying all or any portion of the principal of or interest on
the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that
may affect the covenants or the performance of this Indenture; and the Company (to the extent it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

     Section 4.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver
to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the
fiscal year ending on December 31, 2011) an Officers’ Certificate stating whether or not the
signers thereof have knowledge of any failure by the Company to comply with all conditions and
covenants then required to be performed under this Indenture and, if so, specifying each such
failure and the nature thereof.

     In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event
within 60 days after the Company becomes aware of the occurrence of any Event of Default or
Default, an Officers’ Certificate setting forth the details of such Event of Default or Default,
its status and the action that the Company proposes to take with respect thereto.

     Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the Company will
execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purposes of this Indenture.

     Section 4.10. Furnishing Guarantees. The Company shall cause any Subsidiary formed or
acquired after the date hereof (other than any foreign Subsidiaries), that guarantees any of the
Company’s indebtedness for money borrowed or guarantees the obligations of any Restricted
Subsidiary, to become a Guarantor by causing, as promptly as practicable, but in any event not
later than the date on which such Subsidiary becomes a guarantor of any other Indebtedness of the
Company or any Subsidiary, such Subsidiary to execute and deliver to the Trustee a Guarantee in
substantially the form of the Form of Notation of Guarantee and the Company shall furnish to the
Trustee an Officers’ Certificate stating that all conditions precedent, if any, provided for in
this Indenture relating to the proposed action have been complied with, and an Opinion of Counsel
stating that, in the opinion of such counsel, all such conditions precedent have been complied
with.

ARTICLE 5

Lists of Holders and Reports by the Company and the Trustee

     Section 5.01. Lists of Holders. The Company covenants and agrees that it will furnish or
cause to be furnished to the Trustee, semi-annually, not more than 15 days after each February 15
and August 15 in each year beginning with August 15, 2011, and at such other times as the Trustee
may request in writing, within 30 days after receipt by the Company of any such request (or such
lesser time as the Trustee may reasonably request in order to enable it to timely provide any
notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require
of the names and addresses of the Holders as of a date not more than 15 days (or such other date as
the Trustee may reasonably request in order to so provide any such notices) prior to the time such
information is furnished, except that no such list need be furnished so long as the Trustee is
acting as Note Registrar.

     Section 5.02. Preservation and Disclosure of Lists. The Trustee shall preserve, in as
current a form as is reasonably practicable, all information as to the names and addresses of the
Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained
by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any list
furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

ARTICLE 6

Defaults and Remedies

     Section 6.01. Events of Default. The following events shall be “Events of Default” with
respect to the Notes:

          (a) default in any payment of interest on any Note when due and payable, and the default
continues for a period of 30 calendar days;

          (b) default in the payment of principal of any Note when due and payable on the Maturity Date,
upon Optional Redemption, upon required repurchase, upon declaration of acceleration or otherwise;

          (c) failure by the Company to comply with its obligation to convert the Notes in accordance
with this Indenture upon exercise of a Holder’s conversion right and such failure continues for
five business days;

          (d) failure by the Company to issue a Fundamental Change Company Notice in accordance with
Section 15.01(c) or notice of a specified corporate event in accordance with Section 14.01(b)(ii)
or Section 14.01(b)(iii), in each case when due;

          (e) failure by the Company to comply with its obligations under Article 11;

          (f) failure by the Company to comply with any of its other agreements contained in the Notes
or this Indenture for 60 days after it receives written notice from the Trustee or the Holders of
at least 25% in principal amount of the Notes then outstanding;

          (g) default by the Company or any Significant Subsidiary with respect to any mortgage,
agreement or other instrument under which there may be outstanding, or by which there may be
secured or evidenced, any indebtedness for money borrowed in excess of $20 million in the aggregate
of the Company and/or any Significant Subsidiary, whether such indebtedness now exists or shall
hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable
or (ii) constituting a failure to pay the principal or interest of any such debt when due and
payable at its stated maturity, upon required repurchase, upon declaration of acceleration or
otherwise;

          (h) a final judgment for the payment of $20 million or more (excluding any amounts covered by
insurance) rendered against the Company or any Significant Subsidiary, which judgment is not
discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has
expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been
extinguished;

23

 

          (i) the Company or any Significant Subsidiary shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to the Company or any
such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now
or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or
other similar official of the Company or any such Significant Subsidiary or any substantial part of
its property, or shall consent to any such relief or to the appointment of or taking possession by
any such official in an involuntary case or other proceeding commenced against it, or shall make a
general assignment for the benefit of creditors, or shall fail generally to pay its debts as they
become due; or

          (j) an involuntary case or other proceeding shall be commenced against the Company or any
Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the
Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of the Company or such Significant Subsidiary or
any substantial part of its property, and such involuntary case or other proceeding shall remain
undismissed and unstayed for a period of 30 consecutive days.

     Section 6.02. Acceleration; Rescission and Annulment. In case one or more Events of Default
shall have occurred and be continuing (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be 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) of which a Responsible Officer of the Trustee has actual knowledge, then, and in each and
every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j)
with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of
the Notes shall have already become due and payable, either the Trustee or the Holders of at least
25% in aggregate principal amount of the Notes then outstanding determined in accordance with
Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may,
and the trustee at the request of such Holders shall, declare 100% of the principal of, and accrued
and unpaid interest on, all the Notes to be due and payable immediately, and upon any such
declaration the same shall become and shall automatically be immediately due and payable, anything
in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of
Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its
Significant Subsidiaries occurs and is continuing, the principal of, and accrued and unpaid
interest on, all Notes shall be automatically and immediately due and payable.

     This provision, however, is subject to the conditions that if, at any time after the principal
of the Notes shall have been so declared due and payable, and before any judgment or decree for the
payment of the monies due shall have been obtained or entered as hereinafter provided, the Company
shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and
unpaid interest upon all Notes and the principal of any and all Notes that shall have become due
otherwise than by acceleration (with interest on overdue installments of accrued and unpaid
interest to the extent that payment of such interest is enforceable under applicable law, and on
such principal at the rate borne by the Notes plus one percent at such time) and amounts due to the
Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or
decree of a court of competent jurisdiction and (2) any and all existing Events of Default under
this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if
any, on Notes that shall have become due solely by such acceleration, shall have been cured or
waived pursuant to Section 6.09, then and in every such case the Holders of a majority in aggregate
principal amount of the Notes then outstanding, by written notice to the Company and to the
Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and
annul such declaration and its consequences and such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver or rescission and annulment shall extend to or shall affect any subsequent
Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding
anything to the contrary herein, no such waiver or rescission and annulment shall extend to or
shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of,
or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required
or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of
the Notes.

     Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the
Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default
relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b)
shall for the 365 days immediately following the

24

 

occurrence of such an Event of Default consist exclusively of the right to receive Additional
Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of the Notes
outstanding. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not
in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the
Company so elects, such Additional Interest shall be payable in the same manner and on the same
dates as ordinary interest on the Notes. Such Additional Interest shall accrue from, and
including, the date on which such Event of Default first occurs, to, but excluding, the 365th day
thereafter (or such earlier date on which such Event of Default shall have been cured or waived).
On the 366th day after such Event of Default (if the Event of Default relating to the Company’s
failure to file is not cured or waived prior to such 366th day), such Additional Interest shall
cease to further accrue and the Notes will be subject to acceleration as provided in Section 6.02.
In the event the Company does not elect to pay Additional Interest following an Event of Default in
accordance with this Section 6.03, the Notes shall be subject to acceleration as provided in
Section 6.02.

     In order to elect to pay Additional Interest as the sole remedy during the first 365 days
after the occurrence of any Event of Default described in the immediately preceding paragraph, the
Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election
prior to the beginning of such 365-day period. Upon the failure to timely give such notice, the
Notes shall be immediately subject to acceleration as provided in Section 6.02.

     Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described
in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the
Trustee, pay to it, for the benefit of the Holders of the Notes, the whole amount then due and
payable on the Notes for principal and interest, if any, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the
Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and
as trustee of an express trust, may institute a judicial proceeding for the collection of the sums
so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the
same against the Company or any other obligor upon the Notes and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the property of the Company or any other
obligor upon the Notes, wherever situated.

     In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any
other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Company or such other obligor, the property of the Company or such other obligor, or in the
event of any other judicial proceedings relative to the Company or such other obligor upon the
Notes, or to the creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case
of any judicial proceedings, to file such proofs of claim and other papers or documents and to take
such other actions as it may deem necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative
to the Company or any other obligor on the Notes, its or their creditors, or its or their property,
and to collect and receive any monies or other property payable or deliverable on any such claims,
and to distribute the same after the deduction of any amounts due the Trustee under Section 7.06;
and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or
similar official is hereby authorized by each of the Holders to make such payments to the Trustee,
as administrative expenses, and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including agents and counsel fees, and
including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of
such distribution. To the extent that such payment of reasonable compensation, expenses, advances
and disbursements out of the estate in any such proceedings shall be denied for any reason, payment
of the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property that the Holders of the Notes may be entitled to
receive in such proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

25

 

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

     All rights of action and of asserting claims under this Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Notes.

     In any proceedings brought by the Trustee (and in any proceedings involving the interpretation
of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held
to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the
Notes parties to any such proceedings.

     In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and
annulment or for any other reason or shall have been determined adversely to the Trustee, then and
in every such case the Company, the Holders, and the Trustee shall, subject to any determination in
such proceeding, be restored respectively to their several positions and rights hereunder, and all
rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though
no such proceeding had been instituted.

     Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the
Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of such monies, upon
presentation of the several Notes, and stamping thereon the payment, if only partially paid, and
upon surrender thereof, if fully paid:

     First, to the payment of all amounts due the Trustee under Section 7.06;

     Second, in case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in
the order of the date due of the payments of such interest and cash due upon conversion, as the
case may be, with interest (to the extent that such interest has been collected by the Trustee)
upon such overdue payments at the rate borne by the Notes at such time, such payments to be made
ratably to the Holders entitled thereto;

     Third, in case the principal of the outstanding Notes shall have become due, by declaration of
acceleration or otherwise, and be unpaid to the payment of the whole amount (including, if
applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon
conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest
on the overdue principal and, to the extent that such interest has been collected by the Trustee,
upon overdue installments of interest at the rate borne by the Notes at such time, and in case such
monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes,
then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase
Price and the cash due upon conversion) and interest without preference or priority of principal
over interest, or of interest over principal or of any installment of interest over any other
installment of interest, or of any Note over any other Note, ratably to the aggregate of such
principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon
conversion) and accrued and unpaid interest; and

     Fourth, to the payment of the remainder, if any, to the Company.

     Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of
principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due,
or the right to receive payment or delivery of the consideration due upon conversion, no Holder of
any Note shall have any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon

26

 

or under or with respect to this Indenture, or for the appointment of a receiver, trustee,
liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

          (a) such Holder previously shall have given to the Trustee written notice of an Event of
Default and of the continuance thereof, as hereinbefore provided;

          (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall
have made written request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder;

          (c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to
it against any loss, liability or expense that may be incurred therein or thereby;

          (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity,
shall have neglected or refused to institute any such action, suit or proceeding; and

          (e) no direction that, in the opinion of the Trustee, is inconsistent with such written
request shall have been given to the Trustee by the Holders of a majority in principal amount of
the Notes outstanding within such 60-day period pursuant to Section 6.09,

it being understood and intended, and being expressly covenanted by the taker and Holder of every
Note with every other taker and Holder and the Trustee that no one or more Holders shall have any
right in any manner whatever by virtue of or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain
priority over or preference to any other such Holder, or to enforce any right under this Indenture,
except in the manner herein provided and for the equal, ratable and common benefit of all Holders
(except as otherwise provided herein). For the protection and enforcement of this Section 6.06,
each and every Holder and the Trustee shall be entitled to such relief as can be given either at
law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including
the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable) of, (y)
accrued and unpaid interest on, and (z) the consideration due upon conversion of, such Note, on or
after the respective due dates expressed or provided for in such Note or in this Indenture, or to
institute suit for the enforcement of any such payment or deliver, as the case may be, on or after
such respective dates against the Company shall not be impaired or affected without the consent of
such Holder.

     Section 6.07. Proceedings by Trustee. In case of an Event of Default the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

     Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph
of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of
any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the
Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any
such right or power, or shall be construed to be a waiver of any such Default or Event of Default
or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy
given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

27

 

     Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The
Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined
in accordance with Section 8.04 shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall
not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such direction. The
Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights
of any other Holder or that would involve the Trustee in personal liability. The Holders of a
majority in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past
Default or Event of Default hereunder and its consequences, except (i) a default in the payment of
accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change
Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of
Section 6.01, (ii) a failure by the Company to deliver the consideration due upon conversion of the
Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot
be modified or amended without the consent of each Holder of an outstanding Note affected. Upon
any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their
former positions and rights hereunder; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event
of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or
Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been
cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default or impair any right consequent thereon.

     Section 6.10. Notice of Defaults. The Trustee shall, within 90 days after its actual
knowledge of the occurrence and continuance of a Default, mail to all Holders as the names and
addresses of such Holders appear upon the Note Register, notice of all Defaults known to a
Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such
notice; provided that, except in the case of a Default in the payment of the principal of
(including the Option Repurchase Price or the Fundamental Change Repurchase Price, if applicable),
or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the
consideration due upon conversion, the Trustee shall be protected in withholding such notice if and
so long as a committee of Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders.

     Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, 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, the filing by
any party litigant in such suit of an undertaking to pay the costs of such suit and that such court
may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of this Section 6.11
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any
suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and
unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change
Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) on or
after the due date expressed or provided for in such Note or to any suit for the enforcement of the
right to convert any Note in accordance with the provisions of Article 14.

Section 7.01 and Section 7.02.

          (e) No provision of this Indenture shall require the Trustee to expend or risk

including, without limitation, its right to be indemnified, are extended to, and shall be

other Person employed to act hereunder.

          (h) In no event shall the Trustee be responsible or liable for special, indirect, or

          (i) The Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture.

          (j) The Trustee shall not be liable for any action taken, suffered, or omitted to be taken by

Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for the correctness of the same. The

Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation
Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee

Agent, Bid Solicitation Agent or Note Registrar.

     Section 7.05. Monies and Shares of Common Stock to Be Held in Trust. All monies and shares
of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received. Money and shares of Common Stock held by the

     Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay
to the Trustee from time to time, and the Trustee shall be entitled to, compensation for all
services rendered by it hereunder in any capacity (which shall not be limited by any provision of

writing between the Trustee and the Company, and the Company will pay or

30

 

reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances
reasonably incurred or made by the Trustee in accordance with any of the provisions of this
Indenture in any capacity thereunder (including the reasonable compensation and the expenses and
disbursements of its agents and counsel and of all Persons not regularly in its employ) except any
such expense, disbursement or advance as shall have been caused by its negligence, willful
misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under
this Indenture and any other document or transaction entered into in connection herewith and its
directors, officers, employees, agents and any authenticating agent for, and to hold them harmless
against, any loss, claim, damage, liability or expense incurred without negligence, willful
misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees,
or such agent or authenticating agent, as the case may be, and arising out of or in connection with
the acceptance or administration of this trust or in any other capacity hereunder, including the
costs and expenses of defending themselves against any claim of liability in the premises,
including costs of investigation, counsel fees and expenses, damages judgments and amounts paid in
settlement. The obligations of the Company under this Section 7.06 to compensate or indemnify the
Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be
secured by a lien to which the Notes are hereby made subordinate on all money or property held or
collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust
herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive
payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability
or indebtedness of the Company. The obligation of the Company under this Section 7.06 shall
survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or
the Trustee. The Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend
to the officers, directors, agents and employees of the Trustee.

     Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee and its agents and any authenticating agent incur expenses or render services after an
Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws.

     Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section
7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any
action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness and bad faith on
the part of the Trustee, be deemed to be conclusively proved and established by an Officers’
Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of negligence,
willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the
faith thereof.

     Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000. If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of any supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by
giving written notice of such resignation to the Company and by mailing notice thereof to the
Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice
of resignation, the Company shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment within 60 days after the mailing of such
notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to
the Company and the Holders, petition any court of competent jurisdiction for the appointment of a
successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least
six months may, subject to the provisions of Section 6.11, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

31

 

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

          (i) the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.08 and shall fail to resign after written request therefor by the Company
or by any such Holder, or

          (ii) the Trustee shall become incapable of acting, or shall be adjudged a
bankrupt or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or of
its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors,
one copy of which instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee, or, subject to the provisions of Section 6.11, any Holder who has been a bona
fide holder of a Note or Notes for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

          (c) The Holders of a majority in aggregate principal amount of the Notes at the time
outstanding, as determined in accordance with Section 8.04, may at any time remove the Trustee and
nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten
days after notice to the Company of such nomination the Company objects thereto, in which case the
Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a)
provided, may petition any court of competent jurisdiction for an appointment of a successor
trustee.

          (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 7.10.

     Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided
in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or
removal of the predecessor trustee shall become effective and such successor trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the successor trustee, the
trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of
Section 7.06, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee,
the Company shall execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien to which the Notes are hereby made subordinate on all money or
property held or collected by such trustee as such, except, subject to Section 6.05, for funds held
in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant
to the provisions of Section 7.06.

     No successor trustee shall accept appointment as provided in this Section 7.10 unless at the
time of such acceptance such successor trustee shall be eligible under the provisions of Section
7.08.

     Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each
of the Company and the successor trustee, at the written direction and at the expense of the
Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the
Holders at their addresses as they shall appear on the Note Register. If the Company fails to mail
such notice within ten days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company.

     Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the
Trustee may be merged or converted or with which it may be consolidated, or any corporation or
other entity resulting from any

32

 

merger, conversion or consolidation to which the Trustee shall be a party, or any corporation
or other entity succeeding to all or substantially all of the corporate trust business of the
Trustee (including the administration of this Indenture), shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the part of any of the
parties hereto; provided that in the case of any corporation or other entity succeeding to all or
substantially all of the corporate trust business of the Trustee such corporation or other entity
shall be eligible under the provisions of Section 7.08.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent appointed by such successor trustee may
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of
the successor trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any
predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

     Section 7.12. Trustee’s Application for Instructions from the Company. Any application by
the Trustee for written instructions from the Company (other than with regard to any action
proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders
of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The Trustee shall not
be liable for any action taken by, or omission of, the Trustee in accordance with a proposal
included in such application on or after the date specified in such application (which date shall
not be less than three Business Days after the date any officer that the Company has indicated to
the Trustee should receive such application actually receives such application, unless any such
officer shall have consented in writing to any earlier date), unless, prior to taking any such
action (or the effective date in the case of any omission), the Trustee shall have received written
instructions in accordance with this Indenture in response to such application specifying the
action to be taken or omitted.

ARTICLE 8

Concerning the Holders

     Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders
of a specified percentage in aggregate principal amount of the Notes may take any action (including
the making of any demand or request, the giving of any notice, consent or waiver or the taking of
any other action), the fact that at the time of taking any such action, the Holders of such
specified percentage have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Holders in person or by agent or proxy appointed in
writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly
called and held in accordance with the provisions of Article 9, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders. Whenever the Company
or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the
Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the
record date for determining Holders entitled to take such action. The record date if one is
selected shall be not more than fifteen days prior to the date of commencement of solicitation of
such action.

     Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01,
Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or
proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may
be prescribed by the Trustee or in such manner as shall be reasonably satisfactory to the Trustee.
The holding of Notes shall be proved by the Note Register or by a certificate of the Note
Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section
9.06.

     Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose
name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute
owner of such Note (whether or not such

33

 

Note shall be overdue and notwithstanding any notation of ownership or other writing thereon
made by any Person other than the Company or any Note Registrar) for the purpose of receiving
payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid
interest on such Note, for conversion of such Note and for all other purposes; and neither the
Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall
be affected by any notice to the contrary. All such payments so made to any Holder for the time
being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for monies payable upon any such Note. Notwithstanding
anything to the contrary in this Indenture or the Notes following an Event of Default, any Holder
of a beneficial interest in a Global Note may directly enforce against the Company such Holder’s
right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture.

     Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or
other action under this Indenture, Notes that are owned by the Company or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company
shall be disregarded and deemed not to be outstanding for the purpose of any such determination;
provided that for the purposes of determining whether the Trustee shall be protected in relying on
any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are
so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the
pledgee is not the Company or a Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company. In the case of a dispute as to such right, any
decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.
Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’
Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by
or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee
shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein
set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any
such determination.

     Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not
after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by
the Holders of the percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be
included in the Notes the Holders of which have consented to such action may, by filing written
notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such
action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon
all future Holders and owners of such Note and of any Notes issued in exchange or substitution
therefor or upon registration of transfer thereof, irrespective of whether any notation in regard
thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon
registration of transfer thereof.

     Section 9.02. Call of Meetings by Trustee. The Trustee may at any time call a meeting of
Holders to take any action specified in Section 9.01, to be held at such time and at such place as
the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and
the place of such meeting and in general terms the action proposed to be taken at such meeting and
the establishment of any record date pursuant to Section 8.01, shall be mailed to Holders of such
Notes at their addresses as they shall appear on the Note Register. Such notice shall also be
mailed to the Company. Such notices shall be mailed not less than twenty nor more than ninety days
prior to the date fixed for the meeting.

     Any meeting of Holders shall be valid without notice if the Holders of all Notes then
outstanding are present in person or by proxy or if notice is waived before or after the meeting by
the Holders of all Notes outstanding, and if the Company and the Trustee are either present by duly
authorized representatives or have, before or after the meeting, waived notice.

     Section 9.03. Call of Meetings by Company or Holders. In case at any time the Company,
pursuant to a Board Resolution, or the Holders of at least 10% in aggregate principal amount of the
Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written
request setting forth in reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such
request, then the Company or such Holders may determine the time and the place for such meeting and
may call such meeting to take any action authorized in Section 9.01, by mailing notice thereof as
provided in Section 9.02.

     Section 9.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a

or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and
their counsel and any representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

     Section 9.05. Regulations. Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders,
in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct
of the meeting as it shall think fit.

     The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting,
unless the meeting shall have been called by the Company or by Holders as provided in Section 9.03,
in which case the Company or the Holders calling the meeting, as the case may be, shall in like
manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting
shall be elected by vote of the Holders of a majority in principal amount of the Notes represented
at the meeting and entitled to vote at the meeting.

     Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or proxy
holder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented
by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any
Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding.
The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or
instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other
Holders. Any meeting of Holders duly called pursuant to the provisions of Section 9.02 or Section
9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal
amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting
may be held as so adjourned without further notice.

     Section 9.06. Voting. The vote upon any resolution submitted to any meeting of Holders shall
be by written ballot on which shall be subscribed the signatures of the Holders or of their
representatives by proxy and the

35

 

outstanding principal amount of the Notes held or represented by them. The permanent chairman
of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting
for or against any resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of
the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of votes on any vote
by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting
forth a copy of the notice of the meeting and showing that said notice was mailed as provided in
Section 9.02. The record shall show the principal amount of the Notes voting in favor of or
against any resolution. The record shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company
and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting.

     Any record so signed and verified shall be conclusive evidence of the matters therein stated.

     Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be
deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any
rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the
exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under
any of the provisions of this Indenture or of the Notes.

ARTICLE 10

     Section 10.01. Supplemental Indentures Without Consent of Holders. The Company, when

may from time to time and at any time enter into an indenture or indentures supplemental hereto for
one or more of the following purposes:

          (a) to cure any ambiguity, or correct any omission, defect or inconsistency in this Indenture,
so long as such action will not adversely affect the interests of Holders of the Notes; provided
that any such supplemental indenture made solely to conform the provisions of this Indenture to the
Offering Memorandum shall be deemed not to adversely affect the interests of Holders of the Notes;

          (b) to provide for the assumption by a Successor Company of the obligations of the Company
under this Indenture pursuant to Article 11;

          (c) to add guarantees with respect to the Notes;

          (e) to add to the covenants for the benefit of the Holders or surrender any right or power

          (f) to make any change that does not adversely affect the rights of any Holder;

          (g) fix a Specified Dollar Amount that shall apply to all future conversions of Notes and
provide that the Company shall be required to satisfy its Conversion Obligations by paying cash
with respect to such Specified Dollar Amount;

          (h) to provide for a successor Trustee; or

          (i) release any Guarantor except as provided in Article 17 hereof.

     Upon the written request of the Company and subject to Section 10.05, the Trustee is hereby
authorized to join with the Company in the execution of any such supplemental indenture, to make
any further appropriate agreements and stipulations that may be therein contained, but the Trustee
shall not be obligated to, but may in its

36

 

discretion, enter into any supplemental indenture that affects the Trustee’s own rights,
duties, immunities or liabilities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed
by the Company and the Trustee without the consent of the Holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 10.02.

     Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced
as provided in Article 8) of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding (determined in accordance with Article 8 and including, without
limitation, consents obtained in connection with a repurchase of, or tender offer or exchange offer
for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the
Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of
modifying in any manner the rights of the Holders; provided, however, that, without the consent of
each Holder of an outstanding Note affected, no such supplemental indenture shall:

          (a) reduce the rate of or extend the stated time for payment of interest on any Note;

          (b) reduce the principal of or extend the Maturity Date of any Note;

          (c) make any change that impairs or adversely affects the right of a Holder to convert any
Note or the Conversion Rate thereof;

          (d) reduce the Redemption Price, Option Repurchase Price or Fundamental Change Repurchase
Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation
to make such payments, whether through an amendment or waiver of provisions in the Indenture
(including the definitions contained therein) or otherwise;

          (e) make any Note payable in currency other than that stated in the Note;

          (f) change the ranking of the Notes;

          (g) impair the right of any Holder to receive payment of principal of and interest, including
Additional Interest or Contingent Interest, if any, on such Holder’s Notes or to institute suit for
the enforcement of any payment on or with respect to such Holder’s Note; or

          (h) make any change in this Article 10 that requires each Holder’s consent or in the waiver
provisions in Section 6.01 or Section 6.09.

     Upon the written request of the Company, and upon the filing with the Trustee of evidence of
the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee’s own rights, duties, immunities or liabilities under this Indenture or otherwise, in
which case the Trustee may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

     The consent of the Holders is not necessary under this Section 10.02 to approve the particular
form of any proposed supplemental indenture. It is sufficient if such consent approves the
substance thereof. After any such supplemental indenture becomes effective, the Company shall mail
to the Holders a notice briefly describing such supplemental indenture. However, the failure to
give such notice to all the Holders, or any defect in the notice, will not impair or affect the
validity of the supplemental indenture.

     Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to
be modified and amended in accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this

37

 

Indenture of the Trustee, the Company and the Holders shall thereafter be determined,
exercised and enforced hereunder subject in all respects to such modifications and amendments and
all the terms and conditions of any such supplemental indenture shall be and be deemed to be part
of the terms and conditions of this Indenture for any and all purposes.

     Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of
any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s
discretion and expense, bear a notation as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion
of the Board of Directors, to any modification of this Indenture contained in any such supplemental
indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by
the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 18.10)
and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then
outstanding.

     Section 10.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In
addition to the documents required by Section 18.05, the Trustee shall receive an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant hereto complies with the requirements of this Article 10 and is permitted or
authorized by the Indenture.

ARTICLE 11

Consolidation, Merger, Sale, Conveyance and Lease

     Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 11.02, the Company shall not consolidate with, merge with or into, or sell, convey,
transfer or lease all or substantially all of its properties and assets to another Person, unless:

          (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the
Company, shall be a corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia, and the Successor Company (if not the
Company) shall expressly assume, by supplemental indenture all of the obligations of the Company
under the Notes and this Indenture; and

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

     For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of one or more Subsidiaries of the Company to
another Person, which properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of the Company to another Person.

     Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation,
merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by
supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of
the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery
or payment, as the case may be, of any consideration due upon conversion of the Notes and the due
and punctual performance of all of the covenants and conditions of this Indenture to be performed
by the Company, such Successor Company shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein as the party of the first part, except in the case
of a lease of all or substantially all of the Company’s properties and assets. Such Successor
Company 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 Notes issuable hereunder which theretofore shall not have been signed
by the Company and delivered to the Trustee; and, upon the order of such Successor Company 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 Notes that previously shall have been signed and delivered by the Officers of the
Company to the Trustee for authentication, and any Notes that such Successor Company thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued
shall in all respects have the same legal rank and benefit under this Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of this Indenture as though all of
such Notes had been issued at the date of the execution hereof. In the event of any such

38

 

consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon
compliance with this Article 11 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 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the
case of a lease, such Person shall be released from its liabilities as obligor and maker of the
Notes and from its obligations under this Indenture.

     In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes
in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as
may be appropriate.

     Section 11.03. Opinion of Counsel to Be Given to Trustee. No consolidation, merger, sale,
conveyance, transfer or lease shall be effective unless 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 and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture, complies with the
provisions of this Article 11.

ARTICLE 12

Immunity of Incorporators, Stockholders, Officers and Directors

     Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment
of the principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or
otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement
of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of
the creation of any indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future,
of the Company or of any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a consideration for,
the execution of this Indenture and the issue of the Notes.

ARTICLE 13

Contingent Interest

     Section 13.01. Contingent Interest.

          (a) Contingent interest on the Notes (“Contingent Interest”) shall accrue and the Company
shall pay such Contingent Interest to the Holders beginning with the Interest Payment Period
commencing March 1, 2018, during any Interest Payment Period with respect to which the average
Trading Price for the five Trading Days ending on and including the third Trading Day immediately
preceding the first day such Interest Payment Period is greater than or equal to 120% of the
principal amount of Notes, in which case the Contingent Interest payable on each $1,000 principal
amount of the Notes for such Interest Payment Period shall be equal to 0.375% per annum of such
average Trading Price during such five Trading Day reference period; and

          (b) The Company shall provide prompt written notice to the Bid Solicitation Agent identifying
the three independent nationally recognized securities dealers referred to in the definition of
Trading Price, along with appropriate contact information for each. For purposes of this Article
13, if the Bid Solicitation Agent cannot reasonably obtain at least one bid for $2,000,000
principal amount of Notes from an independent nationally recognized securities dealer when
determining the Trading Price, then the Trading Price of the Notes on any date of determination
will equal the product of (i) the applicable Conversion Rate for the Notes and (ii) the average
closing price of the Common Stock for the five Trading Days ending on that date of determination.

          (c) The Bid Solicitation Agent shall not determine the Trading Price unless requested by the
Company to make such determination. The Company shall have no obligation to make such a request
unless a Holder of Notes provides the Company with reasonable evidence that the Trading Price of
the Notes for the five Trading Days ending on and including the third Trading Day immediately
preceding the first day of such Interest Payment Period is greater than or equal to 120% of the
principal amount of Notes as set forth in Section 13.01(a), at which time the Company shall
instruct the Bid Solicitation Agent to determine the average Trading Price in

39

 

accordance with Section 13.01(a). The Bid Solicitation Agent’s determination of the Trading
Price shall be conclusive absent manifest error and subject to Section 13.01(b).

     Section 13.02. Trustee’s Responsibilities in Respect of Contingent Interest. The Company
shall determine whether Holders are entitled to receive Contingent Interest, and if it so
determines, shall provide notice to the Trustee and all Holders of record of the Notes.
Simultaneously with providing such notice, the Company shall publish a notice containing the
information included therein once in a newspaper of general circulation in The City of New York or
publish such information on the Company’s website or through such other public medium as the
Company may use at such time. 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.

     Section 13.03. Payment of Contingent Interest. Contingent Interest for any Interest Payment
Period shall be paid on the applicable Interest Payment Date to the Holder in whose name any Note
is registered on the Note Register on the corresponding Regular Record Date. Contingent Interest
due under this Article 13 shall be treated for all purposes of this Indenture like any other
interest accruing on the Note.

     Section 13.04. Tax Treatment of the Securities. For United Stated federal income tax
purposes, the Company agrees, and by acceptance of a beneficial interest in the Notes each Holder
and any beneficial owner of the Notes shall be deemed to have agreed, to (1) treat the Notes as
debt instruments that are subject to Treasury Regulation section 1.1275-4 or any successor
provision (the “Contingent Payment Regulations”), (2) treat the sum of the amount of any cash plus
the fair market value of any Common Stock received upon conversion of the Notes as a contingent
payment for purposes of the Contingent Payment Regulations, (3) accrue interest with respect to the
Notes as original discount for United States federal income tax purposes according to the
“noncontingent bond method” set forth in the Contingent Payment Regulations and (4) be bound by the
Company’s determination of the “comparable yield” and “projected payment schedule,” each within the
meaning of the Contingent Payment Regulations, with respect to the Notes. The Company agrees to
provide promptly to any Holder of Notes, upon written request, the issue price, amount of tax
original issue discount, issue date, comparable yield and projected payment schedule. Any such
written request should be sent to Altra Holdings, Inc. at the following address: 300 Granite
Street, Suite 201, Braintree, Massachusetts 02184, Attention: Chief Financial Officer.

ARTICLE 14

Conversion of Notes

     Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions
of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert
all or any portion (if the portion to be converted is $2,000 principal amount or an integral
multiple of $1,000 thereafter) of such Note (i) at any time prior to the close of business on the
Business Day immediately preceding March 1, 2030, but only under the conditions and during the
periods set forth in Section 14.01(b), and (ii) irrespective of the conditions described in Section
14.01(b), on or after March 1, 2030 and prior to the close of business on the second Business Day
immediately preceding the Maturity Date, in each case, at an initial conversion rate of 36.0985
shares of Common Stock (subject to adjustment as provided in Section 14.04, the “Conversion Rate”)
per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the
“Conversion Obligation”).

          (b) (i) The Notes may be surrendered for conversion during the five Business Day period
immediately after any 10 consecutive Trading Day period (the “Measurement Period”) in which the
Trading Price, as determined following a request by a Holder of Notes in accordance with this
subsection (b)(i), for each Trading Day of the Measurement Period was less than 97% of the product
of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading
Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this
subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company
shall provide written notice to the Bid Solicitation Agent of the three independent nationally
recognized securities dealers selected by the Company pursuant to the definition of Trading Price,
along with appropriate contact information for each. The Bid Solicitation Agent shall have no
obligation to determine the Trading Price unless the Company has requested such determination, and
the Company shall have no obligation to make such request unless a Holder provides the Company with
reasonable evidence that the Trading Price would be

40

 

less than 97% of the product of the Last Reported Sale Price of the Common Stock and the
Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent to determine
the Trading Price beginning on the next Trading Day and on each successive Trading Day until the
Trading Price is greater than or equal to 97% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate. If the Company does not instruct the Bid Solicitation Agent
to determine the Trading Price when obligated as provided in the preceding sentence, or if the
Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to
make such determination, then, in either case, for the purposes of this Section 14.01(b)(i), the
Trading Price shall be deemed to be less than 97% of the product of the Last Reported Sale Price of
the Common Stock and the Conversion Rate on each Trading Day of such failure. In addition, for
purposes of this Section 14.01(b)(i), if the Bid Solicitation Agent cannot reasonably obtain at
least one bid for $2,000,000 principal amount of Notes from an independent nationally recognized
securities dealer when determining the Trading Price , then the Trading Price shall be deemed to be
less than 97% of the product of the Last Reported Sale Price of the Common Stock and the Conversion
Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the
Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after
the Trading Price condition set forth above has been met, the Trading Price is greater than or
equal to 97% of the product of the Last Reported Sale Price of the Common Stock and the applicable
Conversion Rate, the Company shall so notify the Holders of the Notes, the Trustee and the
Conversion Agent (if other than the Trustee).

          (ii) If the Company elects to:

          (A) issue to all or substantially all holders of its Common Stock any
rights, options or warrants entitling them, for a period of not more than 45
calendar days after the announcement date of such issuance, to subscribe for
or purchase shares of its Common Stock, at a price per share that is less
than the average of the Last Reported Sale Prices of the Common Stock for
the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of such issuance; or

          (B) distribute to all or substantially all holders of its Common Stock
the Company’s assets, debt securities or rights to purchase securities of
the Company, which distribution has a per share value, as reasonably
determined by the Board of Directors, exceeding 10% of the Last Reported
Sale Price of the Common Stock on the Trading Day preceding the date of
announcement for such distribution,

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the
Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior to the
Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the
Notes may be surrendered for conversion at any time until the earlier of (1) the close of business
on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution
and (2) the Company’s announcement that such issuance or distribution will not take place, even if
the Notes are not otherwise convertible at such time.

          (iii) If at any time a transaction or event that constitutes a Fundamental
Change or a Make-Whole Fundamental Change occurs, regardless of whether a Holder has
the right to require the Company to repurchase the Notes pursuant to Section 15.01,
or if the Company is a party to a consolidation, merger, binding share exchange, or
transfer or lease of all or substantially all of its assets, pursuant to which the
Common Stock would be converted into cash, securities or other assets, the Notes may
be surrendered for conversion at any time from or after the date that is 30
Scheduled Trading Days prior to the anticipated effective date of the transaction
(or, if later, the Business Day after the Company gives notice of such transaction)
until 30 Trading Days after the actual effective date of such transaction or, if
such transaction also constitutes a Fundamental Change, until the related
Fundamental Change Repurchase Date (or, in each case, if earlier, until the
Company’s announcement that such transaction or event will not take place). The
Company shall notify Holders, the Trustee and the Conversion Agent (if other than
the Trustee) (i) as promptly as practicable following the date the Company publicly
announces such transaction but in no event less than 30 Scheduled Trading Days prior
to the anticipated effective date of such transaction or (ii) if the Company does
not have knowledge of such transaction at least 30

41

 

Scheduled Trading Days prior to the anticipated effective date of such
transaction, within one Business Day of the date upon which the Company receives
notice, or otherwise becomes aware, of such transaction but in no event later than
the actual effective date of such transaction.

          (iv) The Notes may be surrendered for conversion during any fiscal quarter
(and only during such fiscal quarter) commencing after June 30, 2011, if the Last
Reported Sale Price of the Common Stock is greater than or equal to 130% of the
Conversion Price for at least 20 Trading Days (whether or not consecutive) during
the period of 30 consecutive Trading Days ending on the last Trading Day of the
immediately preceding fiscal quarter. The Company, shall determine at the beginning
of each fiscal quarter commencing after June 30, 2011 whether the Notes may be
surrendered for conversion in accordance with this clause (iv) and shall notify the
Company and the Trustee if the Notes become convertible in accordance with this
clause (iv).

          (v) If the Company calls any or all of the Notes for redemption pursuant to
Article 16, then Holders may surrender Notes that have been so called for redemption
at any time prior to the close of business on the third Scheduled Trading Day
immediately preceding the Redemption Date, even if the Notes are not otherwise
convertible at such time, after which time the Holder’s right to convert shall
expire, unless the Company defaults in the payment of the Redemption Price, in which
case a Holder of Notes may convert its Notes until the Redemption Price has been
paid or duly provided for.

     Section 14.02. Conversion Procedure; Settlement Upon Conversion.

          (a) Unless the Conversion Date of any conversion in accordance with this Article 14 is on or
after the Irrevocable Net Share Settlement Election Date, if any, and subject to this Section
14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or
deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount
of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if
applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of
this Section 14.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock,
together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance
with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth
in this Section 14.02.

          (i) All conversions occurring on or after March 1, 2030 or after the Company’s
issuance of a Redemption Notice with respect to the Notes and prior to the related
Redemption Date shall be settled using the same Settlement Method.

          (ii) Prior to March 1, 2030, except for any conversions that occur after the
Company’s issuance of a Redemption Notice with respect to the Notes but prior to the
related Redemption Date, the Company shall use the same Settlement Method for all
conversions occurring on the same Conversion Date, but the Company shall not have
any obligation to use the same Settlement Method with respect to conversions that
occur on different Trading Days.

          (iii) Unless a Conversion Date is on or after the Irrevocable Net Share
Settlement Election Date, if any, if, in respect of any such Conversion Date (or the
period beginning on, and including, March 1, 2030 and ending on, and including, the
third Scheduled Trading Day immediately preceding the Maturity Date, as the case may
be), the Company elects to deliver a notice (the “Settlement Notice”) of the
relevant Settlement Method in respect of such Conversion Date (or such period, as
the case may be), the Company, through the Trustee, shall deliver such Settlement
Notice to converting Holders no later than the close of business on the Trading Day
immediately following the relevant Conversion Date (or, in the case of any
conversions occurring after the date of issuance of a Redemption Notice with respect
to the Notes and prior to the related Redemption Date, in such Redemption Notice).
The Company must select a settlement method and inform holders of such settlement
method by no later than March 1, 2030 in the case of conversions occurring on or
after March 1, 2030. If the Company does not elect a Settlement Method prior to the
deadline set forth in the immediately preceding sentence, the

42

 

Company shall no longer have the right to elect Cash Settlement or Physical
Settlement and the Company shall be deemed to have elected Combination Settlement in
respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000
principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall
specify the relevant Settlement Method and in the case of an election of Combination
Settlement, the relevant Settlement Notice shall indicate the Specified Dollar
Amount. If the Company delivers a Settlement Notice electing Combination Settlement
in respect of its Conversion Obligation but does not indicate a Specified Dollar
Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be
$1,000.

          (iv) The cash, shares of Common Stock or combination of cash and shares of
Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall
be computed as follows:

          (A) if the Company elects to satisfy its Conversion Obligation in
respect of such conversion by Physical Settlement, the Company shall deliver
to the converting Holder a number of shares of Common Stock equal to the
product of (1) the aggregate principal amount of Notes to be converted,
divided by $1,000, and (2) the Conversion Rate in effect on the Conversion
Date;

          (B) if the Company elects to satisfy its Conversion Obligation in
respect of such conversion by Cash Settlement, the Company shall pay to the
converting Holder in respect of each $1,000 principal amount of Notes being
converted cash in an amount equal to the sum of the Daily Conversion Values
for each of the 40 consecutive Trading Days during the related Observation
Period; and

          (C) if the Company elects (or is deemed to have elected) to satisfy its
Conversion Obligation in respect of such conversion by Combination
Settlement, the Company shall pay or deliver, as the case may be, in respect
of each $1,000 principal amount of Notes being converted, a Settlement
Amount equal to the sum of the Daily Settlement Amounts for each of the 40
consecutive Trading Days during the related Observation Period.

          (v) The Daily Settlement Amounts (if applicable) and the Daily Conversion
Values (if applicable) shall be determined by the Company promptly following the
last day of the Observation Period. Promptly after such determination of the Daily
Settlement Amounts or the Daily Conversion Values, as the case may be, and the
amount of cash payable in lieu of any fractional share, the Company shall notify the
Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement
Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
payable in lieu of fractional shares of Common Stock. The Trustee and the
Conversion Agent (if other than the Trustee) shall have no responsibility for any
such determination.

          (b) The Company shall have the right, in its sole discretion and without the consent of any
Holder, to irrevocably elect (an “Irrevocable Net Share Settlement Election”), by notice to
Holders, the Trustee and the Conversion Agent, promptly at any time prior to March 1, 2030, that
Combination Settlement, with a Specified Dollar Amount equal to $1,000), apply to each and every
conversion of any Security whose Conversion Date is on or after the date (the “Irrevocable Net
Share Settlement Election Date”) the Company provides such notice, which election, once given,
shall be irrevocable; provided, however, that the Company shall have the right to irrevocably
renounce its right to make an Irrevocable Net Share Settlement Election by notifying Holders, the
Trustee and the Conversion Agent at any time prior to the earlier of (A) March 1, 2030 and (B) the
Company’s exercise of the Irrevocable Net Share Settlement Election, in which case no Irrevocable
Net Share Settlement Election is permitted to be made after such notice; if the Company has duly
made an Irrevocable Net Share Settlement Election, then the Company need not, and may not,
thereafter provide a Settlement Method Election Notice in respect of any conversion of a Note.

43

 

          (c) Subject to Section 14.02(f), before any Holder of a Note shall be entitled to convert a
Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the
procedures of the Depositary in effect at that time and, if required, pay funds equal to interest
payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(i) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an
irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a
facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in
writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any shares of Common
Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender
such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement
and transfer documents), at the office of the Conversion Agent, (3) if required, furnish
appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest
payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(i). The Trustee (and if different, the Conversion Agent) shall notify the Company of
any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice
of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has
also delivered a Fundamental Change Repurchase Notice or an Option Repurchase Notice to the Company
in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice or
Such Option Repurchase Notice in accordance with Section 15.03, respectively.

     If more than one Note shall be surrendered for conversion at one time by the same Holder, the
Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so
surrendered.

          (d) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in
subsection (b) above. Except as otherwise provided in Section 14.03(b) or Section 14.07, the
Company shall pay or deliver, as the case may be, the consideration due in respect of the
Conversion Obligation on the third Business Day immediately following the relevant Conversion Date,
if the Company elects Physical Settlement, or on the third Business Day immediately following the
last Trading Day of the Observation Period, in the case of any other Settlement Method. If any
shares of Common Stock are due to converting Holders, the Company shall issue or cause to be
issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or
nominees, certificates or a book-entry transfer through the Depositary for the full number of
shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s
Conversion Obligation.

          (e) In case any Note shall be surrendered for partial conversion, the Company shall execute
and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the
Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal
amount equal to the unconverted portion of the surrendered Note, without payment of any service
charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum
sufficient to cover any transfer tax or similar governmental charge required by law or that may be
imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon
such conversion being different from the name of the Holder of the old Notes surrendered for such
conversion.

          (f) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or
similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion,
unless the tax is due because the Holder requests such shares to be issued in a name other than the
Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than
the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such
Holder in accordance with the immediately preceding sentence.

          (g) Except as provided in Section 14.04, no adjustment shall be made for dividends on any
shares issued upon the conversion of any Note as provided in this Article 14.

          (h) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Global Note as to the reduction in the
principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee.

44

 

          (i) Upon conversion, a Holder shall not receive any separate cash payment for accrued and
unpaid interest, if any, except as set forth below. The Company’s settlement of the Conversion
Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the
Note and accrued and unpaid interest, if any, to, but not including, the Conversion Date. As a
result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be
deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of
Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be
deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing,
if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes
as of the close of business on such Regular Record Date will receive the interest payable on such
Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered
for conversion during the period from the close of business on any Regular Record Date to the open
of business on the immediately following Interest Payment Date must be accompanied by funds equal
to the amount of interest payable on the Notes so converted; provided that no such payment shall be
required (1) if the Company has specified a Redemption Date that is after a Regular Record Date and
on or prior to the corresponding Interest Payment Date; (2) if the Company has specified a
Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date; (3) for conversions following the Regular Record Date for the
interest payment due on March 1, 2031 or (4) to the extent of any overdue interest, if any such
amounts exist at the time of conversion with respect to such Notes.

          (j) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on
the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by
Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company
elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be.
Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for
conversion.

          (k) The Company shall not issue any fractional share of Common Stock upon conversion of the
Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon
conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical
Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period
(in the case of Combination Settlement). For each Note surrendered for conversion, if the Company
has elected Combination Settlement, the full number of shares that shall be issued upon conversion
thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable
Observation Period and any fractional shares remaining after such computation shall be paid in
cash.

     Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes.

          (a) If a Make-Whole Fundamental Change occurs on or prior to March 1, 2018 and a Holder elects
to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall,
under the circumstances described below, increase the Conversion Rate for the Notes so surrendered
for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as
described below. A conversion of Notes shall be deemed for these purposes to be “in connection
with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the
Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up
to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase
Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change
but for the proviso in clause (b) of the definition thereof, the 30th Trading Day immediately
following the Effective Date of such Make-Whole Fundamental Change).

          (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change
pursuant to Section 14.01(b)(iii), the Company shall, at its option, satisfy the related Conversion
Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with
Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change
described in clause (b) of the definition of Fundamental Change, the Reference Property is composed
entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole
Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price
for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of
converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares),

45

 

multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to
Holders in cash on the third Business Day following the Conversion Date. The Company shall notify
the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press
release announcing such Effective Date no later than five Business Days after such Effective Date.

          (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased
shall be determined by reference to the table below, based on the date on which the Make-Whole
Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock
Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental
Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change
described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash
amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale
Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading
Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

          (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as
of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock
Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by
a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment
giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so
adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the
same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

          (e) The following table sets forth the number of Additional Shares to be received per $1,000
principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date
set forth below:

     The exact Stock Prices and Effective Dates may not be set forth in the table above, in
which case:

          (i) if the Stock Price is between two Stock Prices in the table above or the
Effective Date is between two Effective Dates in the table, the number of Additional
Shares shall be determined by a straight-line interpolation between the number of
Additional Shares set forth for the higher and lower Stock Prices and the earlier
and later Effective Dates, as applicable, based on a 365-day year;

          (ii) if the Stock Price is greater than $90.00 per share (subject to adjustment
in the same manner as the Stock Prices set forth in the column headings of the
table above pursuant to subsection (d) above), no Additional Shares shall be added
to the Conversion Rate; and

          (iii) if the Stock Price is less than $20.52 per share (subject to adjustment
in the same manner as the Stock Prices set forth in the column headings of the table
above pursuant to subsection (d) above), no Additional Shares shall be added to the
Conversion Rate.

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock
issuable upon conversion exceed 48.7329 per $1,000 principal amount of Notes, subject to adjustment
in the same manner as the Conversion Rate pursuant to Section 14.04.

46

 

          (f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant
to Section 14.04 in respect of a Make-Whole Fundamental Change.

     Section 14.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company if any of the following events occurs, except that the Company shall
not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in
the case of a share split or share combination), at the same time and upon the same terms as
holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions
described in this Section 14.04, without having to convert their Notes, as if they held a number of
shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (divided by
$1,000) of Notes held by such Holder.

          (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on
shares of its Common Stock, or if the Company effects a share split or share combination, the
Conversion Rate shall be adjusted based on the following formula:

where,

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to
the open of business on the Ex-Dividend Date of
such dividend or distribution, or immediately
prior to the open of business on the effective
date of such share split or share combination, as
applicable;
	 
	 	 	 	 
	CR1

	 	=
	 	the Conversion Rate in effect immediately after
the open of business on such Ex-Dividend Date or
effective date;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the open of business on such
Ex-Dividend Date or effective date; and
	 
	 	 	 	 
	OS1

	 	=
	 	the number of shares of Common Stock outstanding
immediately after giving effect to such dividend,
distribution, share split or share combination.

Any adjustment made under this Section 14.04(a) shall become effective immediately after the open
of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the
open of business on the effective date for such share split or share combination, as applicable.
If any dividend or distribution of the type described in this Section 14.04(a) is declared but not
so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

          (b) If the Company issues to all or substantially all holders of its Common Stock any rights,
options or warrants entitling them, for a period of not more than 45 calendar days after the
announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a
price per share that is less than the average of the Last Reported Sale Prices of the Common Stock
for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the date of announcement of such issuance, the Conversion Rate shall be increased based
on the following formula:

where,

47

 

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend
Date for such issuance;
	 
	 	 	 	 
	CR1

	 	=
	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding immediately prior to the open of business on
such Ex-Dividend Date;
	 
	 	 	 	 
	X

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

	 	=
	 	the number of shares of Common Stock equal to the aggregate price payable to exercise such
rights, options or warrants, divided by the average of the Last Reported Sale Prices of the
Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of the issuance of such rights, options or
warrants.

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the open of business on
the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not
delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be
decreased to the Conversion Rate that would then be in effect had the increase with respect to the
issuance of such rights, options or warrants been made on the basis of delivery of only the number
of shares of Common Stock actually delivered. If such rights, options or warrants are not so
issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect
if such Ex-Dividend Date for such issuance had not occurred.

     For purposes of this Section 14.04(b), in determining whether any rights, options or warrants
entitle the holders to subscribe for or purchase shares of the Common Stock at less than such
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement for
such issuance, and in determining the aggregate offering price of such shares of Common Stock,
there shall be taken into account any consideration received by the Company for such rights,
options or warrants and any amount payable on exercise or conversion thereof, the value of such
consideration, if other than cash, to be determined by the Board of Directors or a committee
thereof.

          (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness,
other assets or property or rights, options or warrants to acquire its Capital Stock or other
securities, to all or substantially all holders of the Common Stock, excluding (i) dividends,
distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or
Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an
adjustment was effected pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the
provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital
Stock, evidences of indebtedness, other assets or property or rights, options or warrants to
acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the
Conversion Rate shall be increased based on the following formula:

where,

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend
Date for such distribution;

48

 

	 	 	 	 	 

	CR1

	 	=
	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of the Common Stock over the 10 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 or a committee thereof) of the
Distributed Property with respect to each outstanding share of the Common Stock on the
Ex-Dividend Date for such distribution.

Any increase made under the portion of this Section 14.04(c) above shall become effective
immediately after the open of business on the Ex-Dividend Date for such distribution. If such
distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate
that would then be in effect if such dividend or distribution had not been declared.
Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same
terms as holders of the Common Stock receive the Distributed Property, the amount of Distributed
Property such Holder would have received if such Holder owned a number of shares of Common Stock
equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board
of Directors determines the “FMV” (as defined above) of any distribution for purposes of this
Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it
shall in doing so consider the prices in such market over the same period used in computing the
Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on,
and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

     With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment
of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit of the
Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national
securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following
formula:

Where,

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
	 
	 	 	 	 
	CR1

	 	=
	 	the Conversion Rate in effect immediately after the end of the Valuation Period;
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity
interest distributed to holders of the Common Stock applicable to one share of the Common
Stock (determined by reference to the definition of Last Reported Sale Price as set forth
in Section 1.01 as if references therein to Common Stock were to such Capital Stock or
similar equity interest) over the first 10 consecutive Trading Day period after, and
including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
	 
	 	 	 	 
	MP0

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

The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last Trading
Day of the Valuation Period; provided that in respect of any conversion during the Valuation
Period, references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days
shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the
Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate.

49

 

     For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights,
options or warrants distributed by the Company to all holders of its Common Stock entitling them to
subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such
shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of
future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of
this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be
required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or
warrants shall be deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right,
option or warrant, including any such existing rights, options or warrants distributed prior to the
date of this Indenture, are subject to events, upon the occurrence of which such rights, options or
warrants become exercisable to purchase different securities, evidences of indebtedness or other
assets, then the date of the occurrence of any and each such event shall be deemed to be the date
of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such
rights (in which case the existing rights, options or warrants shall be deemed to terminate and
expire on such date without exercise by any of the holders thereof). In addition, in the event of
any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or
other event (of the type described in the immediately preceding sentence) with respect thereto that
was counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options
or warrants that shall all have been redeemed or purchased without exercise by any holders thereof,
upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such
rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be
readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case
may be, as though it were a cash distribution, equal to the per share redemption or purchase price
received by a holder or holders of Common Stock with respect to such rights, options or warrants
(assuming such holder had retained such rights, options or warrants), made to all holders of Common
Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or
warrants that shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

     For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), any dividend or
distribution to which this Section 14.04(c) is applicable that also includes one or both of:

          (A) a dividend or distribution of shares of Common Stock to which
Section 14.04(a) is applicable (the “Clause A Distribution”); or

          (B) a dividend or distribution of rights, options or warrants to which
Section 14.04(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is
applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this
Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause
A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b)
with respect thereto shall then be made, except that, if determined by the Company (I) the
“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be
the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in
the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding
immediately prior to the open of business on such Ex-Dividend Date or effective date” within the
meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such
Ex-Dividend Date” within the meaning of Section 14.04(b).

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

50

 

     where,

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 
	CR1

	 	=
	 	the Conversion Rate in effect immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the Last Reported Sale Price of the Common Stock on the Trading Day immediately
preceding the Ex-Dividend Date for such dividend or distribution;
	 
	 	 	 	 
	C

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

Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution. If such dividend or
distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the
Board of Directors determines not to make or pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared.
Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as
holders of shares of the Common Stock, the amount of cash that such Holder would have received if
such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Ex-Dividend Date for such cash dividend or distribution.

          (e) If the Company or any of its Subsidiaries make a payment in respect of a tender 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 the Common Stock exceeds the Last Reported Sale
Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be
increased based on the following formula:

where,

	 	 	 	 	 

	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to
the close of business on the 10th Trading Day
immediately following, and including, the Trading
Day next succeeding the date such tender or
exchange offer expires;
	 
	 	 	 	 
	CR1

	 	=
	 	the Conversion Rate in effect immediately after
the close of business on the 10th Trading Day
immediately following, and including, the Trading
Day next succeeding the date such tender or
exchange offer expires;
	 
	 	 	 	 
	AC

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

51

 

	 	 	 	 	 

	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the date such tender or
exchange offer expires (prior to giving effect to
the purchase of all shares of Common Stock
accepted for purchase or exchange in such tender
or exchange offer);
	 
	 	 	 	 
	OS1

	 	=
	 	the number of shares of Common Stock outstanding
immediately after the date such tender or exchange
offer expires (after giving effect to the purchase
of all shares of Common Stock accepted for
purchase or exchange in such tender or exchange
offer); and
	 
	 	 	 	 
	SP1

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the 10 consecutive Trading
Day period commencing on, and including, the
Trading Day next succeeding the date such tender
or exchange offer expires.

The adjustment to the Conversion Rate under this Section 14.04(e) shall occur at the close of
business on the 10th Trading Day immediately following, and including, the Trading Day next
succeeding the date such tender or exchange offer expires; provided that in respect of any
conversion within the 10 Trading Days immediately following, and including, the expiration date of
any tender or exchange offer, references in this Section 14.04(e) with respect to 10 Trading Days
shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date
that such tender or exchange offer expires and the Conversion Date in determining the Conversion
Rate.

          (f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes,
if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has
converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date
would be treated as the record holder of the shares of Common Stock as of the related Conversion
Date as described under Section 14.02(j) based on an adjusted Conversion Rate for such Ex-Dividend
Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the
Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting
Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the
shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution
or other event giving rise to such adjustment.

          (g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance
of shares of its Common Stock or any securities convertible into or exchangeable for shares of its
Common Stock or the right to purchase shares of its Common Stock or such convertible or
exchangeable securities.

          (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this
Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of
the NASDAQ Global Market or such other principal U.S. national or regional securities exchange on
which the Common Stock is then listed, the Company from time to time may increase the Conversion
Rate by any amount for a period of at least 20 Business Days if the Board of Directors or a
committee thereof determines that such increase would be in the Company’s best interest. In
addition, the Company may (but is not required to) increase the Conversion Rate to avoid or
diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection
with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever
the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company
shall mail to the Holder of each Note at its last address appearing on the Note Register a notice
of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and
such notice shall state the increased Conversion Rate and the period during which it will be in
effect.

          (i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall 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;

52

 

          (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;

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

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

          (v) for accrued and unpaid interest, if any.

          (j) All calculations and other determinations under this Article 14 shall be made by the
Company and shall be made to the nearest one-ten-thousandth (1/10,000) of a share, with five
one-hundred-thousandths (5/100,000) rounded upward. The Company shall not be required to make an
adjustment under this Article 14 unless the adjustment would require a change of at least 1% in the
Conversion Rate. Notwithstanding the immediately preceding sentence, the Company shall carry
forward any adjustments that are less than 1% of the Conversion rate and make such carried-forward
adjustments on each Conversion Date, and each Observation Period Trading Day with respect to any
Conversion Date, for any Notes.

          (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee (and the Conversion Agent if not 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 without inquiry that the last Conversion Rate of
which it has knowledge is still in effect. Promptly after delivery of such certificate, the
Company shall prepare a notice of such adjustment of the 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 each Holder at its last address appearing on the Note
Register of this Indenture. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

          (l) For purposes of this Section 14.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long as the Company
does not pay any dividend or make any distribution on shares of Common Stock held in the treasury
of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock.

     Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the
Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the
period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board
of Directors or a committee thereof shall make appropriate adjustments to each 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
when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily
Settlement Amounts are to be calculated.

     Section 14.06. Shares to Be Fully Paid. 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 conversion of the Notes from time to time as such Notes are presented
for conversion (assuming that at the time of computation of such number of shares, all such Notes
would be converted by a single Holder and that Physical Settlement is applicable).

     Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common
Stock.

          (a) In the case of:

53

 

          (i) any recapitalization, reclassification or change of the Common Stock (other
than changes resulting from a subdivision or combination),

          (ii) any consolidation, merger or combination involving the Company,

          (iii) any sale, lease or other transfer to a third party of the consolidated
assets of the Company and the Company’s Subsidiaries substantially as an entirety or

          (iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for,
stock, other securities, other property or assets (including cash or any combination thereof) (any
such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the
right to convert each $1,000 principal amount of Notes shall be changed into a right to convert
such principal amount of Notes into the kind and amount of shares of stock, other securities or
other property or assets (including cash or any combination thereof) that a holder of a number of
shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would
have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common
Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such
Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture permitted under Section 10.01(f) providing for such
change in the right to convert each $1,000 principal amount of Notes; provided, however, that at
and after the effective time of the Merger Event (A) the Company shall continue to have the right
to determine the form of consideration to be paid or delivered, as the case may be, upon conversion
of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of
the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any shares of
Common Stock that the Company would have been required to deliver upon conversion of the Notes in
accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference
Property that a holder of that number of shares of Common Stock would have been entitled to receive
in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of
Reference Property.

     If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right
to receive more than a single type of consideration (determined based in part upon any form of
stockholder election), then (i) the Reference Property into which the Notes will be convertible
shall be deemed to be the weighted average of the types and amounts of consideration received by
the holders of Common Stock that affirmatively make such an election, and (ii) the unit of
Reference Property for purposes of the immediately preceding paragraph shall refer to the
consideration referred to in clause (i) attributable to one share of Common Stock. If the holders
receive only cash in such Merger Event, then for all conversions that occur after the effective
date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount
of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion
Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the
price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the
Conversion Obligation by paying cash to converting Holders on the third Business Day immediately
following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) of such weighted average as soon as practicable after such
determination is made.

     Such supplemental indenture described in the second immediately preceding paragraph shall
provide for adjustments that shall be as nearly equivalent as is possible to the adjustments
provided for in this Article 14. If, in the case of any Merger Event, the Reference Property
includes shares of stock, securities or other property or assets (including cash or any combination
thereof) of a Person other than the successor or purchasing corporation, as the case may be, in
such Merger Event, then such supplemental indenture shall also be executed by such other Person and
shall contain such additional provisions to protect the interests of the Holders of the Notes as
the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to
the extent required by the Board of Directors and practicable the provisions providing for the
purchase rights set forth in Article 15.

          (b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a)
of this Section 14.07, the Company shall promptly file with the Trustee an Officers’ Certificate
briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset
that will comprise the Reference

54

 

Property after any such Merger Event, any adjustment to be made with respect thereto and that
all conditions precedent have been complied with, and shall promptly mail notice thereof to all
Holders. The Company shall cause notice of the execution of such supplemental indenture to be
mailed to each Holder, at its address appearing on the Note Register provided for in this
Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

          (c) The Company shall not become a party to any Merger Event unless its terms are consistent
with this Section 14.07. None of the foregoing provisions shall affect the right of a holder of
Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of
Common Stock, as applicable, as set forth in Section 14.01 and Section 14.02 prior to the effective
date of such Merger Event.

          (d) The above provisions of this Section shall similarly apply to successive Merger Events.

     Section 14.08. Certain Covenants.

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

          (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose
of conversion of Notes 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, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be.

          (c) The Company further covenants that if at any time the Common Stock shall be listed on any
national securities exchange or automated quotation system the Company will list and keep listed,
so long as the Common Stock shall be so listed on such exchange or automated quotation system, any
Common Stock issuable upon conversion of the Notes.

     Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate
(or any adjustment thereto) or whether any facts exist that may require any adjustment (including
any increase) 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 securities, property or cash that may at any time be issued or
delivered upon the conversion of any Note; 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 Note for
the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the
Company contained in this Article. 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 14.07
relating either to the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders upon the conversion of their Notes after any event referred to in such
Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 7.01, may accept (without any independent investigation) 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. Neither the Trustee nor the Conversion
Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has
occurred that makes the Notes eligible for conversion or no longer eligible therefor until the
Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section
14.01(b) with respect to the commencement or termination of such conversion rights, on which
notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to
deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of
any such event or at such other times as shall be provided for in Section 14.01(b).

55

 

     Section 14.10. Notice to Holders Prior to Certain Actions. In case of any:

          (a) action by the Company or one of its Subsidiaries that would require an adjustment in the
Conversion Rate pursuant to Section 14.04 or Section 14.11;

          (b) Merger Event; or

          (c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of
its Subsidiaries;

then, in each case (unless notice of such event is otherwise required pursuant to another provision
of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent
(if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note
Register, as promptly as possible but in any event at least 20 days prior to the applicable date
hereinafter specified, a notice stating (i) the date on which a record is to be taken for the
purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be
taken, the date as of which the holders of Common Stock of record are to be determined for the
purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such
Merger Event, 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 Merger Event,
dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such action by the Company or one of its Subsidiaries,
Merger Event, dissolution, liquidation or winding-up.

     Section 14.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in
effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such
conversion shall be entitled to receive the appropriate number of rights, if any, and the
certificates representing the Common Stock issued upon such conversion shall bear such legends, if
any, in each case as may be provided by the terms of any such stockholder rights plan, as the same
may be amended from time to time. If at the time of conversion, however, the rights have separated
from the shares of Common Stock in accordance with the provisions of the applicable stockholder
rights plan so that the Holders would not be entitled to receive any rights in respect of Common
Stock, if any, issuable upon conversion of the Notes, the Conversion Rate shall be adjusted at the
time of separation as if the Company distributed to all or substantially all holders of Common
Stock shares of Capital Stock of the Company, evidences of its indebtedness, other assets or
property or rights, options or warrants to acquire its Capital Stock or other securities as
provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination
or redemption of such rights.

     Section 14.12. Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding
anything to the contrary in this Indenture, if an event occurs that would result in an increase in
the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules
or listing standards of any national or regional securities exchange that are applicable to the
Company, the Company will, at its option, either obtain stockholder approval of any issuance of
Common Stock upon conversion of the Notes in excess such limitations or deliver cash in lieu of any
shares of Common Stock otherwise deliverable upon conversions in excess of such limitations based
on the Daily VWAP on each Trading Day of the relevant Observation Period in respect of which, in
lieu of delivering shares of Common Stock, the Company delivers cash pursuant to this Section
14.12.

     Section 14.13. Exchange in lieu of conversion.

          (a) When a Holder surrenders Notes for conversion, the Company may direct the Conversion Agent
to surrender, on or prior to the commencement of the applicable Observation Period, such Notes to a
financial institution designated by the Company for exchange in lieu of conversion (a “Designated
Institution”). If the Company so elects, then by the close of business on the second Trading Day
after the Conversion Date, the Company shall notify the Conversion Agent and the Holder
surrendering Notes for conversion that the Company has directed the Designated Institution to make
an exchange in lieu of conversion and the Company shall notify the Conversion Agent whether the
Designated Institution shall deliver, upon exchange, all cash, all shares of Common Stock or a
combination of cash and shares of Common Stock in accordance with the provisions of Section 14.02.

56

 

               (b) In order to accept any Notes surrendered for conversion, the Company shall cause the
Designated Institution to agree with the Company to deliver, in exchange for such Notes, all cash,
shares of Common Stock or a combination of cash and share of Common Stock due upon conversion in
accordance with the provisions of Section 14.02, at the sole option of the Designated Institution
and as is notified to the Conversion Agent by the Company.

               (c) If the Designated Institution accepts Notes surrendered for exchange under this Section
14.13, the Company shall cause such Designated Institution to deliver such cash, shares of Common
Stock or a combination of cash and share of Common Stock in accordance with the provisions of
Section 14.02 to the Conversion Agent (or otherwise coordinate delivery of Common Stock in
accordance with book-entry provisions), and the Conversion Agent shall deliver such cash and/or
shares of Common Stock to the Holder, within the time period specified in Section 14.02(d) (it
being understood that delivery of Common Stock will be coordinated by the Company in accordance
with book-entry procedures, if applicable). Such delivery shall be deemed to satisfy the Company’s
Conversion Obligation with respect to such Holder. Any Notes so exchanged by such Designated
Institution shall remain outstanding for all purposes under this Indenture.

               (d) If the Designated Institution agrees to accept any Notes for exchange but does not timely
deliver the related consideration to the Conversion Agent, or if the Designated Institution does
not accept such Notes for exchange, the Company shall convert such Notes into cash and/or shares of
Common Stock, in accordance with the provisions of Section 14.02.

               (e) For the avoidance of doubt, in no event will the Company’s designation of a financial
institution pursuant to this Section 14.13 require such financial institution to accept any Notes
for exchange.

               (f) The Company shall not pay any consideration to, or otherwise enter into any agreement
with, the Designated Institution for or with respect to such designation.

ARTICLE 15

Repurchase of Notes at Option of Holders

          Section 15.01. Repurchase at Option of Holders Upon a Fundamental Change.

               (a) If a Fundamental Change occurs at any time, each Holder shall have the right, at such
Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any
portion thereof in principal amounts of $2,000 or an integral multiple of $1,000 thereafter, on the
date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20
calendar days or more than 30 calendar days following the date of the Fundamental Change Company
Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest thereon (including any Contingent Interest or Additional Interest, if any) to, but
excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”),
unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to
the Interest Payment Date to which such Regular Record Date relates, in which case the Company
shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such
Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the
principal amount of Notes to be repurchased pursuant to this Article 15.

               (b) Repurchases of Notes under this Section 15.01 shall be made, at the option of the Holder
thereof, upon:

     (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the
Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Depositary’s procedures for surrendering interests in Global
Notes, if the Notes are Global Notes, in each case on or before the close of
business on the Business Day immediately preceding the Fundamental Change Repurchase
Date; and

57

 

     (ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying
Agent at any time after delivery of the Fundamental Change Repurchase Notice
(together with all necessary endorsements for transfer) at the Corporate Trust
Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are
Global Notes, in compliance with the procedures of the Depositary, in each case such
delivery being a condition to receipt by the Holder of the Fundamental Change
Repurchase Price therefor.

          The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall
state:

     (iii) in the case of Physical Notes, the certificate numbers of the Notes to be
delivered for repurchase;

     (iv) the portion of the principal amount of Notes to be repurchased, which must
be $2,000 or an integral multiple of $1,000 thereafter; and

     (v) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice
must comply with appropriate Depositary procedures.

          Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 15.01 shall have the right to
withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date
by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03.

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

               (c) On or before the 20th Business Day after the occurrence of the effective date of a
Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the
Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental
Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of
the repurchase right at the option of the Holders arising as a result thereof. Such notice shall
be by first class mail or, in the case of Global Notes, in accordance with the applicable
procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish
a notice containing the information set forth in the Fundamental Change Company Notice in a
newspaper of general circulation in The City of New York or publish such information on the
Company’s website or through such other public medium as the Company may use at that time. Each
Fundamental Change Company Notice shall specify:

     (i) the events causing the Fundamental Change;

     (ii) the date of the Fundamental Change;

     (iii) the last date on which a Holder may exercise the repurchase right
pursuant to this Article 15;

     (iv) the Fundamental Change Repurchase Price;

     (v) the Fundamental Change Repurchase Date;

     (vi) the name and address of the Paying Agent;

     (vii) if applicable, that the Notes with respect to which a Fundamental Change
Repurchase Notice has been delivered by a Holder may be converted only if the Holder

58

 

withdraws the Fundamental Change Repurchase Notice in accordance with the terms
of this Indenture; and

     (viii) the procedures that Holders must follow to require the Company to
repurchase their Notes.

          No failure of the Company to give the foregoing notices and no defect therein shall limit the
Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 15.01.

          At the Company’s request, the Trustee shall give such notice in the Company’s name and at the
Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change
Company Notice shall be prepared by the Company. Neither the Trustee nor the Paying Agent shall be
responsible for determining if a Fundamental Change has occurred or for delivering a Fundamental
Change Company Notice to Holders.

               (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at
the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been
accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the
case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the
respective Holders thereof any Physical Notes held by it during the acceleration of the Notes
(except in the case of an acceleration resulting from a Default by the Company in the payment of
the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for
book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be
deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the
Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

          Section 15.02. Repurchase at Option of Holders Upon an Option Repurchase Date.

               (a) On March 1, 2018, March 1, 2021 and March 1, 2026, (each an “Option Repurchase Date”),
each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Notes, or any portion thereof in principal amounts of $2,000 or an
integral multiple of $1,000 thereafter, at a repurchase price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon (including any Contingent Interest or Additional
Interest, if any) to, but excluding, the Option Repurchase Date (the “Option Repurchase Price”),
unless the Option Repurchase Date falls after a Regular Record Date but on or prior to the Interest
Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay
the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date,
and the Option Repurchase Price shall be equal to 100% of the principal amount of Notes to be
repurchased pursuant to this Article 15.

               (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder
thereof, upon:

     (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Option Repurchase Notice”) in the form set forth in Attachment 3 to the Form of
Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance
with the Depositary’s procedures for surrendering interests in Global Notes, if the
Notes are Global Notes, in each case at any time from the opening of business on the
date that is 20 Business Days prior to the relevant Option Repurchase Date until the
close of business on the Business Day immediately preceding the relevant Option
Repurchase Date; and

compliance with the procedures of the

59

 

Depositary, in each case such delivery being a condition to receipt by the
Holder of the Fundamental Change Repurchase Price therefor.

     The Option Repurchase Notice in respect of any Notes to be repurchased shall state:

     (i) in the case of Physical Notes, the certificate numbers of the Notes to be
delivered for repurchase;

     (ii) the portion of the principal amount of Notes to be repurchased, which must
be $2,000 or an integral multiple of $1,000 thereafter; and

     (iii) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice
must comply with appropriate Depositary procedures.

          Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Option Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in
whole or in part, such Option Repurchase Notice at any time prior to the close of business on the
Business Day immediately preceding the applicable Option Repurchase Date by delivery of a written
notice of withdrawal to the Paying Agent in accordance with Section 15.03.

     (c) On or before the 20th Business Day prior to each Option Repurchase Date, the Company shall
give notice (the “Option Company Notice”) to all Holders of Notes and the Trustee and the Paying
Agent (in the case of a Paying Agent other than the Trustee) of the Option Repurchase Date and the
repurchase right at the option of the Holders arising as a result thereof. Such notice shall be by
first class mail or, in the case of Global Notes, in accordance with the applicable procedures of
the Depositary Simultaneously with providing such notice, the Company shall publish a notice
containing the information set forth in the Option Company Notice in a newspaper of general
circulation in The City of New York or publish such information on the Company’s website or through
such other public medium as the Company may use at that time. Each Option Company Notice shall
specify:

     (i) that Holders have the right to require the Company to purchase all or any
portion of their Notes pursuant to this Section 15.02;

     (ii) the applicable Option Repurchase Date;

     (iii) the last date on which a Holder may exercise the repurchase right
pursuant to this Article 15;

     (iv) the Option Repurchase Price;

     (v) the name and address of the Paying Agent;

     (vi) if applicable, that the Notes with respect to which a Option Repurchase
Notice has been delivered by a Holder may be converted only if the Holder withdraws
the Option Repurchase Notice in accordance with the terms of this Indenture; and

     (vii) the procedures that Holders must follow to require the Company to
repurchase their Notes.

          No failure of the Company to give the foregoing notices and no defect therein shall limit the
Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 15.01.

60

 

          At the Company’s request, the Trustee shall give such notice in the Company’s name and at the
Company’s expense; provided, however, that, in all cases, the text of such Option Company Notice
shall be prepared by the Company. Neither the Trustee nor the Paying Agent shall be responsible
for determining if an Option Repurchase Date is forthcoming or has occurred or for delivering an
Option Company Notice to Holders.

     (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any Option
Repurchase Date if the principal amount of the Notes has been accelerated, and such acceleration
has not been rescinded, on or prior to such date (except in the case of an acceleration resulting
from a Default by the Company in the payment of the Option Repurchase Price with respect to such
Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes
held by it during the acceleration of the Notes (except in the case of an acceleration resulting
from a Default by the Company in the payment of the Option Repurchase Price with respect to such
Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures
of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as
the case may be, the Option Repurchase Notice with respect thereto shall be deemed to have been
withdrawn.

          Section 15.03. Withdrawal of Fundamental Change Repurchase Notice or Option Repurchase
Notice. (a) A Fundamental Change Repurchase Notice or an Option Repurchase Notice may be withdrawn
(in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust
Office of the Paying Agent in accordance with this Section 15.03 at any time prior to the close of
business on the Business Day immediately preceding the Fundamental Change Repurchase Date or the
Option Repurchase Date, as applicable, specifying:

     (i) the principal amount of the Notes with respect to which such notice of
withdrawal is being submitted,

     (ii) if Physical Notes have been issued, the certificate number of the Note in
respect of which such notice of withdrawal is being submitted, and

     (iii) the principal amount, if any, of such Note that remains subject to the
original Fundamental Change Repurchase Notice or Option Repurchase Notice, as
applicable, which portion must be in principal amounts of $2,000 or an integral
multiple of $1,000 thereafter;

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate
procedures of the Depositary.

provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change
Repurchase Date or the applicable Option Repurchase Date, an amount of cash sufficient to

preceding the Fundamental Change Repurchase Date or Option Repurchase Date, as applicable ) will be
made on the later of (i) the Fundamental Change Repurchase Date or Option Repurchase Date, as
applicable, with respect to such Note (provided the Holder has satisfied the conditions in Section
15.01 or Section 15.02, as applicable) and (ii) the time of book-entry transfer or the delivery of
such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in
the manner required by Section 15.01 or Section 15.02, as applicable, by mailing checks for the
amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note
Register; provided, however, that payments of cash to the Depositary shall be made by wire transfer
of immediately available funds to the account of the Depositary or its nominee. The Trustee shall,
promptly after such payment and upon written demand by the Company, return to the Company any funds
in excess of the Fundamental Change Repurchase Price or the Option Repurchase Price, as applicable.

61

 

               (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date or the
Option Repurchase Date, as applicable, the Trustee (or other Paying Agent appointed by the Company)
holds cash sufficient to make payment on all the Notes or portions thereof that are to be
repurchased on such Fundamental Change Repurchase Date or Option Repurchase Date, then (i) such
Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or
not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee
or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than
the right to receive the Fundamental Change Repurchase Price or Option Repurchase Price, as
applicable).

               (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.01 or
Section 15.02, the Company shall execute and the Trustee shall authenticate and deliver to the
Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased
portion of the Note surrendered.

          Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer, the Company will, if required:

               (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules

               (b) file a Schedule TO or any successor or similar schedule; and

               (c) otherwise comply with all federal and state securities laws in connection with any offer
by the Company to repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 15 to be exercised in
the time and in the manner specified in this Article 15.

          Section 15.06. Purchase by Third Party. Notwithstanding the foregoing provisions of this
Article 15, the Company shall not be required to issue a Fundamental Change Company Notice upon a
Fundamental Change if a third party (i) issues a Fundamental Change Company Notice in the manner,
at the times and otherwise in compliance with the requirements set forth in Section 15.01(c)
applicable to a Fundamental Change Company Notice made by the Company and otherwise complies with
the provisions of this Article 15 as if it were the Company, and (ii) purchases and pays for all
Notes validly tendered and not withdrawn pursuant to such Fundamental Change Company Notice.

ARTICLE 16

Optional Redemption

          Section 16.01. Optional Redemption. The Notes shall not be redeemable by the Company prior to
March 1, 2015. On or after March 1, 2015, and prior to March 1, 2018, if the Last Reported Sale
Price of the Common Stock for 20 or more Trading Days in a period of 30 consecutive Trading Days
ending on the Trading Day prior to the date the Company provides a Redemption Notice exceeds 130%
of the Conversion Price in effect on each such Trading Day, the Company may redeem (an “Optional
Redemption”) all or part of the Notes, upon notice as set forth in Section 16.02, at the applicable
Redemption Price. On or after March 1, 2018, the Company may redeem for cash all or part of the
Notes upon notice as set forth in Section 16.02, at the applicable Redemption Price.

          Section 16.02. Notice of Redemption; Selection of Notes.

               (a) In case the Company exercises its Optional Redemption right to redeem all or, as the case
may be, any part of the Notes pursuant to Section 16.01, it shall fix a date for redemption (each,
a “Redemption Date”) and it or, at its written request received by the Trustee not less than 55
calendar days prior to the Redemption Date (or such shorter period of time as may be acceptable to
the Trustee), 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 (a “Redemption Notice”), not less than 30 nor more than 60
calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or
in part at its last address as the same appears on the Note Register; provided, however, that

62

 

if the Company shall give such notice, it shall also give written notice of the Redemption
Date to the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee);
provided that as long as the Notes are held through The Depository Trust Company, such notice may
be made by electronic transmission to The Depository Trust Company, as Holder. Neither the Trustee
nor the Paying Agent shall be responsible for reviewing the Redemption Notice or for the content or
accuracy of such notice. Neither the Trustee nor the Paying Agent shall have any duty to determine
or calculate the Make-Whole Premium, which shall be determined by the Company in accordance with
the provisions of the Indenture, and the Trustee shall not be under any responsibility to determine
the correctness of any such determination and/or calculation and may conclusively rely on the
correctness thereof.

               (b) The Redemption 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 Redemption Notice by mail or any defect in the Redemption Notice to the Holder
of any Note designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Note.

               (c) Each Redemption Notice shall specify:

     (i) the Redemption Date (which must be a Business Day);

     (ii) the Redemption Price, including the type of consideration to be paid for
the Make-Whole Premium;

     (iii) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Note, and that interest thereon, if any, shall cease to
accrue on and after said date;

     (iv) the place or places where such Notes are to be surrendered for payment of
the Redemption Price;

     (v) that Holders may surrender their Notes for conversion at any time prior to
the close of business on the third Scheduled Trading Day immediately preceding the
Redemption Date;

     (vi) the procedures a converting Holder must follow to convert its Notes and
the Settlement Method and Specified Dollar Amount, if applicable;

     (vii) the Conversion Rate and, if applicable, the number of Additional Shares
added to the Conversion Rate in accordance with Section 14.03;

     (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such
Notes; and

     (ix) in case any Note is to be redeemed in part only, the portion of the
principal amount thereof to be redeemed and on and after the Redemption Date, upon
surrender of such Note, a new Note in principal amount equal to the unredeemed
portion thereof shall be issued.

A Redemption Notice shall be revocable.

               (d) If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select
the Notes or portions thereof of a Global Note or the Notes in certificated form to be redeemed (in
principal amounts of $2,000 or integral multiples of $1,000 thereafter) by lot, or on a pro rata
basis or by another method as may be requested by the Depositary’s applicable procedures. If any
Note selected for partial redemption is submitted for conversion in part after such selection, the
portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the
portion selected for redemption.

63

 

          Section 16.03. Payment of Notes Called for Redemption.

               (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section
16.02, the Notes shall become due and payable on the Redemption Date at the place or places stated
in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of
the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and
redeemed by the Company at the applicable Redemption Price.

               (b) Prior to the open of business on the Redemption Date, the Company shall deposit with the
Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall
segregate and hold in trust as provided in Section 7.05 an amount of cash (in immediately available
funds if deposited on the Redemption Date), sufficient to pay all, or the entire cash portion of,
the Redemption Price of all of the Notes to be redeemed on such Redemption Date.

               (c) Upon any redemption in accordance with this Article 16, the Company shall pay the
Make-Whole Premium with respect to the Notes called for redemption to Holders, at its option, in
cash, shares of Common Stock or a combination of cash and shares of Common Stock and shall specify
the type of consideration for the Make-Whole Premium (and, if a combination, will specify the
dollar amount of the Make-Whole Premium to be paid in cash) in the Notice of Redemption sent by the
Company pursuant to Section 16.02. If the Company does not specify the type of consideration for
the Make-Whole Premium in such Notice of Redemption, the Company shall pay the Make-Whole Premium
entirely in cash.

               (d) Any issuance of shares of Common Stock in respect of the Make-Whole Premium shall be
deemed to have been effected immediately prior to the close of business on the Redemption Date and
the Person or Persons in whose name or names any stock certificate or stock certificates
representing shares of Common Stock shall be issuable upon such redemption shall be deemed to have
become on the Redemption Date the holder or holders of record of the shares represented thereby;
provided, however, that any surrender for redemption on a date when the stock transfer books of the
Company shall be closed shall constitute the Person or Persons in whose name or names the stock
certificate or stock certificates representing such shares are to be issued as the holder or
holders of record of the shares represented thereby for all purposes at the Open of Business on the
next succeeding day on which such stock transfer books are open. No payment or adjustment shall be
made for dividends or distributions on any Common Stock declared prior to the Redemption Date. A
Holder receiving shares of Common Stock in respect of the Make-Whole Premium shall not be entitled
to any rights as a holder of Common Stock, including, among other things, the right to vote and
receive dividends and notices of stockholder meetings, until the Close of Business on the
Redemption Date.

               (e) The Company will not issue a fractional share of Common Stock upon payment of the
Make-Whole Premium. Instead, the Company shall pay cash in lieu of fractional shares based on the
Last Reported Sale Price of Common Stock on the Trading Day prior to the applicable Conversion
Date.

               (f) Any issuance and delivery of stock certificates representing shares of Common Stock on
payment of the Make-Whole Premium shall be made without charge to the Holder of Notes being
redeemed or for any tax or duty in respect of the issuance or delivery of such stock certificates
or the Notes represented thereby; provided, however, that the Company shall not be required to pay
any tax or duty which may be payable in respect of any transfer involved in the issuance or
delivery of stock certificates representing shares of Common Stock in a name other than that of the
Holder of the Notes being redeemed, and no such issuance or delivery shall be made unless the
Persons requesting such issuance or delivery has paid to the Company the amount of any such tax or
duty or has established, to the satisfaction of the Company, that such tax or duty has been paid.

               (g) The Company may, at its option, pay the Make-Whole Premium payable to Holders pursuant to
Section 16.01 upon redemption of the Notes, in shares of Common Stock, if the following conditions
are satisfied:

     (i) The shares of Common Stock to be so issued (A) shall not require
registration under any federal securities law before such shares may be freely
transferable without being subject to any transfer restrictions under the Securities
Act upon redemption or if such

64

 

registration is required, such registration shall be completed and shall become
effective prior to the Redemption Date; and (B) shall not require registration with,
or approval of, any governmental authority under any state law or any other federal
law before shares may be validly issued or delivered upon redemption or if such
registration is required or such approval must be obtained, such registration shall
be completed or such approval shall be obtained prior to the Redemption Date.

     (ii) The shares of Common Stock to be listed upon redemption of Notes hereunder
are, or shall have been, approved for listing on the NASDAQ Global Select Market or
any other stock exchange on which the shares of Common Stock are then listed, in any
case, prior to the Redemption Date, and if the issuance of Common Stock would result
in an amount in excess of the limitations imposed by any shareholder approval rules
or listing standards of any national or regional securities exchange that are
applicable to the Company, the Company shall have previously obtained stockholder
approval of such issuance of Common Stock in excess of such limitations.

     (iii) All shares of Common Stock which may be issued upon redemption of Notes
shall be newly issued shares or treasury shares, shall be duly and validly issued
and fully paid and nonassessable and shall be free from preemptive rights and free
of any lien or adverse claim.

     (iv) If any of the conditions set forth in clauses (i) through (iii) of this
Section 16.03(g) are not satisfied in accordance with the terms thereof, the
Make-Whole Premium shall be paid by the Company only in cash.

               (h) Subject to receipt of funds by the Paying Agent, cash payment for the Notes to be redeemed
shall be made promptly after the later of:

     (i) the Redemption Date for such Notes; and

     (ii) the time of presentation of such Note to the Trustee (or other Paying
Agent appointed by the Company) by the Holder thereof in the manner required by this
Section 16.03.

The Paying Agent shall, promptly after such payment and upon written demand by the Company, return
to the Company any funds in excess of the cash portion of Redemption Price.

          Section 16.04. Restrictions on Redemption. The Company may not redeem any Notes on any date
if (a) the principal amount of the Notes has been accelerated in accordance with the terms of this
Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except
in the case of an acceleration resulting from a Default by the Company in the payment of the
Redemption Price with respect to such Notes) or (b) the Company has not paid or is not
simultaneously paying all accrued and unpaid interest thereon for all periods between Interest
Payment Dates or portions thereof terminating prior to the Redemption Date.

          Section 16.05. No Registration Obligation on Redemption. In the event of any redemption of
the Notes, the Company shall not be required to:

               (a) issue, register the transfer of or exchange any Note during the 15 calendar day period
prior to the date on which a Redemption Notice is deemed to have been given to all Holders of Notes
to be redeemed; or

               (b) register the transfer of or exchange any Notes so selected for redemption, in whole or in
part, except the unredeemed portion of any Notes being redeemed in part.

ARTICLE 17

GUARANTEE OF NOTES

          Section 17.01. Unconditional Guarantee. Each Guarantor, if any, hereby jointly and
severally, unconditionally and irrevocably guarantees (such guarantee to be referred to herein as a
“Guarantee”) to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, that: (a) all amounts due with respect to the Notes shall be duly
and punctually paid in full when due, whether upon conversion, at maturity, by acceleration or
otherwise, and interest on the overdue principal (including, without limitation, the Redemption
Price, Option Purchase Price and Fundamental Change Repurchase Price, if applicable) and (to the
extent permitted by law) interest, if any, on the Notes and all other obligations of the Company or
the Guarantors to the Holders or the Trustee hereunder or thereunder and all other obligations
shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any Notes or any of such other
obligations, the same shall be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, whether at maturity, by acceleration or otherwise. Failing
payment when due of any amount so guaranteed, or failing performance of any other obligation of the
Company to the Holders under this Indenture or under the Notes, for whatever reason, each Guarantor
shall be obligated to pay, or to perform or cause the performance of, the same immediately. An
Event of Default under this Indenture or the Notes shall constitute an event of default under each
Guarantee, and shall entitle the Holders of Notes to accelerate the obligations of the Guarantors
hereunder in the same manner and to the same extent as the obligations of the Company.

          Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with
respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of
any judgment against the Company, any action to enforce the same, whether or not a Guarantee is
affixed to any particular Note, or any other circumstance which might otherwise constitute a legal
or equitable discharge or defense of a guarantor. Each of the Guarantors hereby waives the benefit
of diligence, presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands whatsoever and covenants that its Guarantee shall not be
discharged except by complete performance of the obligations contained in the Notes, this Indenture
and each Guarantee. Each Guarantee is a guarantee of payment and not of collection. Each
Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the
Trustee, on the other hand, (a) subject to this Article 17, the maturity of the obligations
guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of each
Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration
in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such
obligations as provided in Article 6 hereof, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantors for the purpose of each Guarantee.

          No stockholder, officer, director, employee or incorporator, past, present or future, of any
Guarantor, as such, shall have any personal liability under any Guarantee by reason of his, her or
its status as such stockholder, officer, director, employee or incorporator.

          Each Guarantor that makes a payment or distribution under its Guarantee shall be entitled to a
contribution from each other Guarantor in an amount pro rata, based on the net assets of each
Guarantor, determined in accordance with United States Generally Accepted Accounting Principles.

          Section 17.02. Limitations on Guarantees; Release or Suspension of Particular Guarantors’
Obligations. The obligations of each Guarantor under its Guarantee will be limited to the maximum
amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor
and after giving effect to any collections from or payments made by or on behalf of any other
Guarantors in respect of the obligations of such other Guarantors under their Guarantees or
pursuant to their contribution obligations under this Indenture, will result in the obligations of
such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer
under federal or state law.

66

 

          Additionally, if any Guarantor is released from its guarantee (rather than a suspension of its
guarantee) of the outstanding indebtedness of the Company or the obligations of any Restricted
Subsidiary as a guarantor of the Company’s Indebtedness, such Guarantor shall be automatically
released from its obligations as Guarantor, and from and after such date, such Guarantor shall
cease to constitute a Guarantor and a Restricted Subsidiary.

          Section 17.03. Execution and Delivery of Guarantee. To further evidence the Guarantee set
forth in Section 17.01, each Guarantor hereby agrees to execute and deliver to the Trustee a
Guarantee in substantially the form of the Form of Notation of Guarantee. Such Guarantee shall be
executed on behalf of each Guarantor by either manual or facsimile signature of an officer or agent
of each Guarantor, each of whom, in each case, shall have been duly authorized to so execute by all
requisite corporate action. The validity and enforceability of any Guarantee shall not be affected
by the fact that it is not affixed to any Note or Notes.

          If an officer or agent of a Guarantor whose signature is on this Indenture or a Guarantee no
longer holds that office at the time the Trustee authenticates a Note to which such Guarantee
relates or at any time thereafter, such Guarantor’s Guarantee of such Note shall be valid
nevertheless.

          The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Guarantor.

          Section 17.04. Release of a Guarantor due to Extraordinary Events. If no Default exists or
would exist under this Indenture, upon the sale or disposition of all or substantially all of the
assets of a Guarantor, or all of the Capital Stock of a Guarantor (including by consolidation,
merger, issuance or otherwise), by the Company or a Subsidiary of the Company, or upon the
consolidation or merger of a Guarantor with or into any Person (in each case, other than to the
Company or an Affiliate of the Company or a Subsidiary of the Company), or if any Guarantor is
dissolved or liquidated, such Guarantor and each Subsidiary of such Guarantor that is also a
Guarantor, or the Person acquiring such assets (in the event of a sale or other disposition of all
or substantially all of the assets of such Guarantor), shall be deemed automatically and
unconditionally released and discharged from all of its obligations under this Article 17 without
any further action required on the part of the Trustee or any Holder.

          The Trustee shall execute any documents reasonably requested by the Company or a Guarantor in
order to evidence the release of such Guarantor from its obligations under its Guarantee of the
Notes under this Article 17.

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

          Section 17.05. Waiver of Subrogation. Until this Indenture is discharged and all of the
Notes are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to
exercise any claim or other rights which it may now or hereafter acquire against the Company that
arise from the existence, payment, performance or enforcement of the Company’s obligations under
the Notes or this Indenture and such Guarantor’s obligations under its Guarantee and this
Indenture, in any such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to participate in any
claim or remedy of the Holders against the Company, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, including, without limitation, the
right to take or receive from the Company, directly or indirectly, in cash or other property or by
set-off or in any other manner, payment or security on account of such claim or other rights. If
any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts
owing to the Trustee or the Holders of Notes under the Notes, this Indenture, or any other document
or instrument delivered under or in connection with such agreements or instruments, shall not have
been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be
paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the
obligations in favor of the Trustee or the Holders, as the case may be, whether matured or
unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it
will receive direct and indirect benefits from the financing arrangements contemplated by this
Indenture and that the waiver set forth in this Section 17.05 is knowingly made in contemplation of
such benefits.

67

 

          Section 17.06. No Set-Off. Each payment to be made by a Guarantor hereunder in respect its
obligations for principal (including, without limitation, the Redemption Price, Option Purchase
Price and Fundamental Change Repurchase Price, if applicable), premium, interest, penalties, fees,
indemnifications, reimbursements, damages and other liabilities payable under this Indenture or any
other documentation governing the Notes shall be payable in the currency or currencies in which
such obligations are denominated, and shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature.

          Section 17.07. Obligations Absolute. The obligations of each Guarantor hereunder are and
shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by
each Guarantor hereunder which may not be recoverable from such Guarantor on the basis of a
Guarantee shall be recoverable from such Guarantor as a primary obligor and principal debtor in
respect thereof.

          Section 17.08. Obligations Continuing. The obligations of each Guarantor hereunder shall be
continuing and shall remain in full force and effect until all the obligations have been paid and
satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver
to the Trustee suitable acknowledgments of its continued liability hereunder and under any other
instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any
action brought against it in respect of any default hereunder being barred by any statute of
limitations now or hereafter in force and, in the event of the failure of a Guarantor so to do, it
hereby irrevocably appoints the Trustee the attorney and agent of such Guarantor to make, execute
and deliver such written acknowledgment or acknowledgments or other instruments as may from time to
time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to
fully maintain and keep in force the liability of such Guarantor hereunder.

          Section 17.09. Obligations Not Reduced. Except as otherwise provided in Sections 17.02 and
17.04, the obligations of each Guarantor hereunder shall not be satisfied, reduced or discharged
except solely by the payment of such principal (including, without limitation, the Redemption
Price, Option Purchase Price and Fundamental Change Repurchase Price, if applicable), premium, if
any, interest, fees and other monies or amounts as may at any time prior to discharge of this
Indenture pursuant to Article 3 be or become owing or payable under or by virtue of or otherwise in
connection with the Notes or this Indenture.

          Section 17.10. Obligations Reinstate. The obligations of each Guarantor hereunder shall
continue to be effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment
shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded
or reclaimed from the Trustee or any of the Holders upon the insolvency, bankruptcy, liquidation or
reorganization of the Company or any Guarantor or otherwise, all as though such payment had not
been made. If demand for, or acceleration of the time for, payment by the Company is stayed upon
the insolvency, bankruptcy, liquidation or reorganization of the Company, all such Indebtedness
otherwise subject to demand for payment or acceleration shall nonetheless be payable by each
Guarantor as provided herein.

          Section 17.11. Obligations Not Affected. Except as otherwise provided in Sections 17.02 and
17.04, the obligations of each Guarantor hereunder shall not be affected, impaired or diminished in
any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any
demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of
the Holders) which, but for this provision, might constitute a whole or partial defense to a claim
against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor
from any of its obligations hereunder or otherwise affect such obligations, whether occasioned by
default of any of the Holders or otherwise, including, without limitation:

               (a) any limitation of status or power, disability, incapacity or other circumstance relating
to the Company or any other Person, including any insolvency, bankruptcy, liquidation,
reorganization, readjustment, composition, dissolution, winding up or other proceeding involving or
affecting the Company or any other Person;

               (b) any irregularity, defect, unenforceability or invalidity in respect of any indebtedness or
other obligation of the Company or any other Person under this Indenture, the Notes or any other
document or instrument;

68

 

               (c) any failure of the Company, whether or not without fault on its part, to perform or comply
with any of the provisions of this Indenture or the Notes, or to give notice thereof to a
Guarantor;

               (d) the taking or enforcing or exercising or the refusal or neglect to take or enforce or
exercise any right or remedy from or against the Company or any other Person or their respective
assets or the release or discharge of any such right or remedy;

               (e) the granting of time, renewals, extensions, compromises, concessions, waivers, releases,
discharges and other indulgences to the Company or any other Person;

               (f) any change in the time, manner or place of payment of, or in any other term of, any of the
Notes, or any other amendment, variation, supplement, replacement or waiver of, or any consent to
departure from, any of the Notes or this Indenture, including, without limitation, any increase or
decrease in any amount due with respect to any of the Notes;

               (g) any change in the ownership, control, name, objects, businesses, assets, capital structure
or constitution of the Company or a Guarantor;

               (h) any merger or amalgamation of the Company or a Guarantor with any Person or Persons;

               (i) the occurrence of any change in the laws, rules, regulations or ordinances of any
jurisdiction by any present or future action of any governmental authority or court amending,
varying, reducing or otherwise affecting, or purporting to amend, vary, reduce or otherwise affect,
any of the obligations of the Company or the Guarantor under this Indenture or a Guarantor under
its Guarantee; and

               (j) any other circumstance (other than by complete, irrevocable payment) that might otherwise
constitute a legal or equitable discharge or defense of the Company under this Indenture or the
Notes or of a Guarantor in respect of its Guarantee hereunder.

          Section 17.12. Waiver. Without in any way limiting the provisions of Section 17.01 hereof,
each Guarantor hereby waives notice of acceptance hereof, notice of any liability of any Guarantor
hereunder, notice or proof of reliance by the Holders upon the obligations of any Guarantor
hereunder, and diligence, presentment, demand for payment on the Company, protest, notice of
dishonor or non-payment of any of the obligations for principal (including, without limitation, the
Redemption Price, Option Purchase Price and Fundamental Change Repurchase Price, if applicable),
premium, interest, penalties, fees, indemnifications, reimbursements, damages and other liabilities
payable under this Indenture or any other documentation governing the Notes, or other notice or
formalities to the Company or any Guarantor of any kind whatsoever.

          Section 17.13. No Obligation to Take Action Against the Company. Neither the Trustee nor any
other Person shall have any obligation to enforce or exhaust any rights or remedies or to take any
other steps under any security for the obligations for principal (including, without limitation,
the Redemption Price, Option Purchase Price and Fundamental Change Repurchase Price, if
applicable), premium, interest, penalties, fees, indemnifications, reimbursements, damages and
other liabilities payable under this Indenture or any other documentation governing the Notes, or
against the Company or any other Person or any Property of the Company or any other Person before
the Trustee is entitled to demand payment and performance by any or all Guarantors of their
liabilities and obligations under their Guarantees or under this Indenture.

          Section 17.14. Dealing with the Company and Others. The Holders, without releasing,
discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of
any Guarantor hereunder and without the consent of or notice to any Guarantor, may:

               (a) grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges
and other indulgences to the Company or any other Person;

69

 

               (b) take or abstain from taking security or collateral from the Company or from perfecting
security or collateral of the Company;

               (c) release, discharge, compromise, realize, enforce or otherwise deal with or do any act or
thing in respect of (with or without consideration) any and all collateral, mortgages or other
security given by the Company or any third party with respect to the obligations or matters
contemplated by this Indenture or the Notes;

               (d) accept compromises or arrangements from the Company;

               (e) apply all monies at any time received from the Company or from any security upon such part
of the Obligations as the Holders may see fit or change any such application in whole or in part
from time to time as the Holders may see fit; and

               (f) otherwise deal with, or waive or modify their right to deal with, the Company and all
other Persons and any security as the Holders or the Trustee may see fit.

          Section 17.15. Default and Enforcement. If any Guarantor fails to pay in accordance with
Section 17.01. hereof, the Trustee may proceed in its name as trustee hereunder in the
enforcement of the Guarantee of any such Guarantor and such Guarantor’s obligations thereunder and
hereunder by any remedy provided by law, whether by legal proceedings or otherwise, and to recover
from such Guarantor the obligations.

          Section 17.16. Amendment, etc. No amendment, modification or waiver of any provision of this
Indenture relating to any Guarantor or consent to any departure by any Guarantor or any other
Person from any such provision will in any event be effective or affect the obligation of any other
Guarantor unless it is signed by such Guarantor and the Trustee.

          Section 17.17. Acknowledgment. Each Guarantor hereby acknowledges communication of the terms
of this Indenture and the Notes and consents to and approves of the same.

          Section 17.18. Costs and Expenses. Each Guarantor shall pay on demand by the Trustee any and
all costs, fees and expenses (including, without limitation, legal fees) incurred by the Trustee,
its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any
Guarantee.

          Section 17.19. No Merger or Waiver; Cumulative Remedies. No Guarantee shall operate by way
of merger of any of the obligations of a Guarantor under any other agreement, including, without
limitation, this Indenture. No failure to exercise and no delay in exercising, on the part of the
Trustee or the Holders, any right, remedy, power or privilege hereunder or under the Notes or the
Guarantees, shall operate as a waiver thereof; nor shall any single or partial exercise of any
right, remedy, power or privilege hereunder or under this Indenture or the Notes or the Guarantees
preclude any other or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges in the Guarantee and under this Indenture,
the Notes and any other document or instrument between a Guarantor and/or the Company and the
Trustee are cumulative and not exclusive of any rights, remedies, powers and privileges provided by
law.

          Section 17.20. Survival of Obligations. Without prejudice to the survival of any of the
other obligations of each Guarantor hereunder, the obligations of each Guarantor under Section
17.01 shall survive until the indefeasible payment in full of the obligations for principal
(including, without limitation, the Redemption Price, Option Purchase Price and Fundamental Change
Repurchase Price, if applicable), premium, interest, penalties, fees, indemnifications,
reimbursements, damages and other liabilities payable under this Indenture or any other
documentation governing the Notes and shall be enforceable against such Guarantor without regard to
and without giving effect to any defense, right of offset or counterclaim available to or which may
be asserted by the Company or any Guarantor.

          Section 17.21. Guarantee in Addition to Other Obligations. The obligations of each Guarantor
under its Guarantee and this Indenture are in addition to and not in substitution for any other
obligations to the Trustee or to

70

 

any of the Holders in relation to this Indenture or the Notes and any guarantees or security
at any time held by or for the benefit of any of them.

          Section 17.22. Severability. Any provision of this Article 17 which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction unless its removal would substantially defeat the basic
intent, spirit and purpose of this Indenture and this Article 17.

          Section 17.23. Successors and Assigns. Each Guarantee shall be binding upon and inure to the
benefit of each Guarantor and the Trustee and the Holders and their respective successors and
permitted assigns, except that no Guarantor may assign any of its obligations hereunder or
thereunder.

made with the approval of the Trustee shall constitute a sufficient notification for every purpose
hereunder.

          In addition to the foregoing, the Trustee agrees to accept and act upon notice, instructions
or directions pursuant to this Indenture sent by unsecured e-mail, facsimile transmission or other
similar unsecured electronic

71

 

methods. If the party elects to give the Trustee e-mail or facsimile instructions (or
instructions by a similar electronic method) and the Trustee in its discretion elects to act upon
such instructions, the Trustee’s understanding of such instructions shall be deemed controlling.
The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly
from the Trustee’s reliance upon and compliance with such instructions notwithstanding such
instructions conflict or are inconsistent with a subsequent written instruction. The party
providing electronic instructions agrees to assume all risks arising out of the use of such
electronic methods to submit instructions and directions to the Trustee, including without
limitation the risk of the Trustee acting on unauthorized instructions, and the risk or
interception and misuse by third parties.

          Section 18.04. Governing Law. THIS INDENTURE AND EACH NOTE, AND ANY CLAIM, CONTROVERSY OR
DISPUTE ARISING UNDER OR RELATED TO THIS INDENTURE AND EACH NOTE SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICTS OF
LAWS PROVISIONS THEREOF).

          Section 18.05. Evidence of Compliance with Conditions Precedent; Certificates and Opinions of
Counsel to Trustee. Upon any application or demand by the Company to the Trustee to take any
action under any of the provisions of this Indenture, the Company shall, if requested by the
Trustee, furnish to the Trustee an Officers’ Certificate stating that such action is permitted by
the terms of this Indenture.

          Each Officers’ Certificate provided for, by or on behalf of the Company in this Indenture and
delivered to the Trustee with respect to compliance with this Indenture (other than the Officers’
Certificates provided for in Section 4.08) shall include (a) a statement that the Person making
such certificate is familiar with the requested action and this Indenture; (b) a brief statement as
to the nature and scope of the examination or investigation upon which the statement contained in
such certificate is based; (c) a statement that, in the judgment of such person, he or she has made
such examination or investigation as is necessary to enable him or her to express an informed
judgment as to whether or not such action is permitted by this Indenture; and (d) a statement as to
whether or not, in the judgment of such Person, such action is permitted by this Indenture.

          Notwithstanding anything to the contrary in this Section 18.05, if any provision in this
Indenture specifically provides that the Trustee shall or may receive an Opinion of Counsel in
connection with any action to be taken by the Trustee or the Company hereunder, the Trustee shall
be entitled to, or entitled to request, such Opinion of Counsel. An Officers’ Certificate
delivered to the Trustee under this Section 18.05 shall be deemed sufficient to satisfy this
provision for purposes of authenticating Notes on the date hereof; provided, however, that in no
event shall the foregoing derogate the Trustee’s entitlement to an Opinion of Counsel at any other
time under this Indenture.

          Section 18.06. Legal Holidays. If any Interest Payment Date (other than an Interest Payment
Date coinciding with the Maturity Date or earlier Fundamental Change Repurchase Date or Option
Repurchase Date) falls on a day that is not a Business Day, such Interest Payment Date shall be
postponed to the next succeeding Business Day. If the Maturity Date or earlier Fundamental Change
Repurchase Date or Option Repurchase Date would fall on a day that is not a Business Day, the
required payment of interest, if any, and principal shall be made on the next succeeding Business
Day, and no interest on such payment shall accrue for the period from and after the Maturity Date
or earlier Fundamental Change Repurchase Date or Option Repurchase Date to such next succeeding
Business Day.

          Section 18.07. No Security Interest Created. Nothing in this Indenture or in the Notes,
expressed or implied, shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any
jurisdiction.

          Section 18.08. Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed
or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any
Conversion Agent, any Bid Solicitation Agent, any authenticating agent, any Note Registrar and
their successors hereunder or the Holders, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

          Section 18.09. Table of Contents, Headings, Etc. The table of contents and the titles and
headings of the articles and sections of this Indenture have been inserted for convenience of
reference only, are not to be considered a part hereof, and shall in no way modify or restrict any
of the terms or provisions hereof.

          Section 18.10. Authenticating Agent. The Trustee may appoint an authenticating agent that
shall be authorized to act on its behalf and subject to its direction in the authentication and
delivery of Notes in connection with the original issuance thereof and transfers and exchanges of
Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section
10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had
been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes.
For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating
agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a
certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be
deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of
authentication. Such authenticating agent shall at all times be a Person eligible to serve as
trustee hereunder pursuant to Section 7.08.

          Any corporation or other entity into which any authenticating agent may be merged or converted
or with which it may be consolidated, or any corporation or other entity resulting from any merger,
consolidation or conversion to which any authenticating agent shall be a party, or any corporation
or other entity succeeding to the corporate trust business of any authenticating agent, shall be
the successor of the authenticating agent hereunder, if such successor corporation or other entity
is otherwise eligible under this Section, without the execution or filing of any paper or any
further act on the part of the parties hereto or the authenticating agent or such successor
corporation or other entity.

          Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Company.
Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a
successor authenticating agent (which may be the Trustee), shall give written notice of such
appointment to the Company and shall mail notice of such appointment to all Holders as the names
and addresses of such Holders appear on the Note Register.

          The Company agrees to pay to the authenticating agent from time to time reasonable
compensation for its services although the Company may terminate the authenticating agent, if it
determines such agent’s fees to be unreasonable.

          The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section
18.10 shall be applicable to any authenticating agent.

          If an authenticating agent is appointed pursuant to this Section, the Notes may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form:

          
                   
                      
           ,

as Authenticating Agent, certifies that this is one of the Notes described

in the within-named Indenture.

	 	 	 	 	 

	By:
	 	 	 	 
	 

	 	 

	 	 
	Authorized Officer	 	 

          Section 18.11. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute
but one and the same instrument.

          Section 18.12. Severability. In the event any provision of this Indenture or in the Notes
shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity,
legality or enforceability of the remaining provisions shall not in any way be affected or
impaired.

73

 

          Section 18.13. Waiver of Jury Trial. EACH OF THE COMPANY, THE GUARANTORS AND THE TRUSTEE
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR
THE TRANSACTION CONTEMPLATED HEREBY.

          Section 18.14. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts that are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

          Section 18.15. Calculations. Except as otherwise provided herein, the Company or its agents
shall be responsible for making all calculations called for under this Indenture or the Notes, and
none of the Trustee, Conversion Agent, Note Registrar, Bid Solicitation Agent or Paying Agent (in
each case, if different from the Company) shall have any responsibility for making such
calculations. These calculations include, but are not limited to, determinations of the Last
Reported Sale Prices of the Common Stock, accrued interest payable on the Notes and the Conversion
Rate of the Notes. The Company or its agents shall make all these calculations in good faith and,
absent manifest error, their calculations shall be final and binding on Holders of Notes. The
Company or its agents shall provide a schedule of their calculations to each of the Trustee and the
Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively
upon the accuracy of their calculations without independent verification. The Trustee will forward
the Company’s or its agent’s calculations to any Holder of Notes upon the request of that Holder at
the sole cost and expense of the Company.

          Section
18.16.   NASDAQ Limitation. Notwithstanding anything therein to the contrary, the listing standards of the NASDAQ Global Select Market and the NASDAQ Global Market generally require the Company
to obtain the approval of its stockholders before entering into certain transactions that potentially result in the
issuance of 20% or more of the Common Stock outstanding at the time the Notes are issued unless the Company
obtains stockholder approval of issuances in excess of such limitations. In accordance with these listing standards, these restrictions will apply at any time when the Notes are outstanding, regardless of whether the Company then
has a class of securities listed on the NASDAQ Global Select Market or the NASDAQ Global Market. Accordingly, we shall be prohibited from redeeming, repurchasing or converting the Notes and from paying any interest or Make-Whole Premium in Common Stock in accordance with the provisions of this Indenture if, as a result of such action, the aggregate number of shares of Common Stock to be issued under such Notes equals or exceeds 20% of the
Common Stock outstanding at the time the Notes are issued. In such event, we will, at our option, either obtain
stockholder approval of such issuances or deliver cash in lieu of any shares otherwise deliverable upon conversions
in excess of such limitations based on the Daily VWAP on each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering Common Stock, we deliver cash pursuant to this paragraph.

Exchanges of Notes” attached hereto, which amount, taken together with the principal amounts of all
other outstanding Notes, shall not, unless permitted by the Indenture, exceed $[_______] in

additional Notes in full as set forth in the Purchase Agreement), in accordance with the rules and
procedures of the Depositary, on March 1, 2031, and interest thereon as set forth below.

          This Note shall bear interest at the rate of 2.75% per year from March 7, 2011, or from the
most recent date to which interest had been paid or provided for to, but excluding, the next

[FORM OF REVERSE OF NOTE]

ALTRA HOLDINGS, INC.

2.75% Convertible Senior Notes due 2031

          This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.75%
Convertible Senior Notes due 2031 (the “Notes”), limited to the aggregate principal amount of
$[_______] (or $[_______] if the Initial Purchasers exercise their option to purchase additional
Notes in full as set forth in the Purchase Agreement), all issued or to be issued under and
pursuant to an Indenture dated as of March 7, 2011 (the “Indenture”), between the Company, the
Guarantors named therein and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), to
which Indenture and all indentures supplemental thereto reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate
principal amount, subject to certain conditions specified in the Indenture.

          In case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or
Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said
declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions and certain exceptions set forth in the Indenture.

          Subject to the terms and conditions of the Indenture, the Company will make all payments and
deliveries in respect of the Fundamental Change Repurchase Price or the Option Repurchase Price, as
applicable, and the principal amount on the Maturity Date, as the case may be, to the Holder who
surrenders a Note to a Paying Agent to collect such payments in respect of the Note.

          The Indenture contains provisions permitting the Company, the Guarantors and the Trustee in
certain circumstances, without the consent of the Holders of the Notes, and in certain other
circumstances, with the consent of the Holders of not less than a majority in aggregate principal
amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute
supplemental indentures modifying the terms of the Indenture and the Notes as described therein.
It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority
in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of
all of the Notes waive any past Default or Event of Default under the Indenture and its
consequences.

          No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal (including the Option Repurchase Price or the Fundamental Change Repurchase Price, if
applicable) of and accrued and unpaid interest on this Note at the place, at the respective times,
at the rate and in the lawful money herein prescribed.

          The Notes are issuable in registered form without coupons in denominations of $2,000 principal
amount and integral multiples of $1,000 thereafter. At the office or agency of the Company
referred to on the face hereof, and in the manner and subject to the limitations provided in the
Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other
authorized denominations, without payment of any service charge but, if required by the Company or
Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed
in connection therewith as a result of the name of the Holder of the new Notes issued upon such
exchange of Notes being different from the name of the Holder of the old Notes surrendered for such
exchange.

          The Notes shall be redeemable at the Company’s option in accordance with the terms and
conditions specified in the Indenture.

          Subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the
Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of
such Holder’s Notes or any portion thereof (in principal amounts of $2,000 or integral multiples of
$1,000 thereafter) on the Fundamental Change Repurchase Date at a price equal to the Fundamental
Change Repurchase Price.

A-3

 

          Subject to the provisions of the Indenture, on each Option Repurchase Date, the Holder has the
right, at such Holders option to require the Company to repurchase for cash all of such Holder’s

      As Representatives of the Initial Purchasers listed in

c/o Jefferies & Company, Inc.

520 Madison Avenue

New York, New York 10022

Ladies and Gentlemen:

     Altra Holdings, Inc., a Delaware corporation (the “Company”), and each of the
Guarantors (as hereinafter defined) hereby agree with you as follows:

          1. Issuance of Securities. Subject to the terms and conditions herein contained, the
Company proposes to issue and sell to the initial purchasers listed on Schedule I (the
“Initial Purchasers”), for whom Jefferies & Company, Inc. (“Jefferies”) and J.P.
Morgan Securities LLC are acting as representatives (the “Representatives”), $75,000,000
aggregate principal amount of 2.75% Convertible Senior Notes due 2031 (the “Initial
Securities”). The Initial Securities will be issued pursuant to an indenture (the
“Indenture”), to be dated as of March 7, 2011, between the Company, the Guarantors and The
Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). In addition, the
Company has granted to the Initial Purchasers an option to purchase up to an additional $10,000,000
aggregate principal amount of its 2.75% Convertible Senior Notes due 2031 on the terms and
conditions and for the purposes set forth in Section 2 (the “Option Securities” and,
together with the Initial Securities, the “Securities”). The Securities will be
convertible into duly and validly issued, fully paid and non-assessable shares of common stock, par
value $.001 per share (the “Common Stock”), of the Company (such shares, the
“Conversion Shares”) on the terms, and subject to the conditions, set forth in the
Indenture. Capitalized terms used, but not defined herein shall have the meanings set forth in the
“Description of the Notes” section of the Final Offering Memorandum (as hereinafter defined).

          The Securities will be offered and sold to the Initial Purchasers pursuant to exemptions from
the registration requirements under the Securities Act of 1933, as amended (the “Act”).
Upon original issuance thereof, and until such time as the same are no longer required under the
applicable requirements of the Act, the Securities shall bear the legends set forth under the
“Notice to Investors” section of the final offering memorandum, dated the date hereof (including
the information incorporated by reference therein, the “Final Offering Memorandum”). The
Company has prepared (i) a preliminary offering memorandum, dated March 1, 2011, including the
information incorporated by reference therein
(the “Preliminary Offering Memorandum”), (ii) a pricing term sheet attached hereto as
Schedule II, which includes pricing terms and other information with respect to the
Securities and the Conversion Shares (the “Pricing Term Sheet”) and (iii) the Final
Offering Memorandum relating to the offer and sale of the

 

 

Securities (the “Offering”).
“Offering Memorandum” means the Preliminary Offering Memorandum and any exhibits and
schedules thereto, including all information incorporated by reference therein, as supplemented by
the Pricing Term Sheet at 4:30 p.m. New York City time on the date hereof (the “Applicable
Time”). No later than the second Business Day following the date hereof, the Company will
prepare and deliver to the Initial Purchasers the Final Offering Memorandum and from and after the
time such Final Offering Memorandum is delivered to the Initial Purchasers, all references herein
to the “Offering Memorandum” shall be deemed collectively to refer to (i) the Preliminary
Offering Memorandum (as supplemented by the Pricing Term Sheet and any exhibits thereto) and (ii)
the Final Offering Memorandum (and any amendment or supplement to either such document), including
exhibits and schedules thereto. The Preliminary Offering Memorandum immediately prior to the
Applicable Time, taken together with the Pricing Term Sheet, is referred to as the “Pricing
Disclosure Package.”

          2. Terms of Offering. The Initial Purchasers have advised the Company, and the
Company understands, that the Initial Purchasers will make offers to sell (the “Exempt
Resales”) some or all of the Securities purchased by the Initial Purchasers hereunder on the
terms set forth in the Pricing Disclosure Package and the Final Offering Memorandum, as amended or
supplemented, to persons (the “Subsequent Purchasers”) whom the Initial Purchasers
reasonably believe to be (i) “qualified institutional buyers” (“QIBs”) as defined in Rule
144A under the Act, as such may be amended from time to time and (ii) non-U.S. persons permitted to
purchase the Securities in offshore transactions in reliance upon Regulation S under the Act and in
compliance with the laws applicable to such persons in jurisdictions outside the United States
(each, a “Reg S Person” and, together with the QIBs, “Eligible Purchasers”).

          Pursuant to the Indenture, all existing and future Domestic Subsidiaries (as defined in the
Indenture) of the Company shall fully and unconditionally guarantee, on a senior basis, to each
holder of the Securities and the Trustee, the payment and performance of the Company’s obligations
under the Indenture and the Securities (each such subsidiary being referred to herein as a
“Guarantor” and each such guarantee being referred to herein as a “Guarantee”).

          This Agreement, the Indenture, the Securities and the Conversion Shares are collectively
referred to herein as the “Documents” and the transactions contemplated hereby and thereby
are collectively referred to herein as the “Transactions.”

          3. Purchase, Sale and Delivery.

	(a)	 	On the basis of the representations, warranties, agreements and covenants herein
contained and subject to the terms and conditions herein set forth, the Company agrees to
issue and sell to the Initial Purchasers, and each of the Initial Purchasers agrees, severally
and not jointly, to purchase from the Company, the respective principal amount of the Initial
Securities set forth opposite such Initial Purchaser’s name in Schedule I hereto, at a
purchase price of 97.00% of the aggregate principal amount thereof.
	 
	(b)	 	The Company hereby grants to the Initial Purchasers an option to purchase up to
$10,000,000 aggregate principal amount of Option Securities at the same purchase price as set
forth above in Section 3(a) for the Initial Securities. Such option is granted for the
purpose of covering over-allotments in the sale of Initial Securities. The option will expire
13 days after the Initial Closing Date (as defined below) and may be exercised in whole or in
part from time to time by written notice being given to the Company by the Representatives.
Such notice shall set forth the aggregate principal amount of Option Securities as to which
the option is being exercised, the names in which the principal amount of Option Securities
are to be registered, the denominations in which the Option Securities are to be issued and
the date and time, as determined by the Representatives, when the Option Securities are to be

	(c)	 	Delivery to the Initial Purchasers of and payment for the Initial Securities shall be

March 7, 2011 (the “Initial Closing Date”) and delivery to the Initial Purchasers of
and payment for any Option Securities shall be made at a closing (the “Option Closing”
and, together with the Initial Closing, the “Closing”) to be held at a time and place
to be agreed by the Company and the Representatives (the “Option Closing Date” and,
together with the Initial Closing Date, the “Closing Date”), in each case, at the New
York City offices of Proskauer Rose LLP.

	(d)	 	The Company shall deliver to the Initial Purchasers one or more certificates
representing the Initial Securities and the Option Securities, as the case may be, in

request, against payment by the Initial Purchasers of the purchase price therefor by
immediately available federal funds bank wire transfer to such bank account or accounts as the
Company shall designate to the Initial Purchasers at least two business days prior to the
applicable Closing Date. The certificates representing the Initial Securities and the Option
Securities, as the case may be, in definitive form shall be made available to the Initial
Purchasers for inspection at the New York offices of Proskauer Rose LLP, Eleven Times Square,
New York, New York 10036 (or such other place as shall be reasonably acceptable to the Initial

          4. Representations and Warranties of the Company and the Guarantors. The Company and
the Guarantors jointly and severally represent and warrant to, and agree with, the Initial
Purchasers that, as of the Applicable Time and as of the applicable Closing Date:

	(a)	 	As of the Applicable Time, the Pricing Disclosure Package and the Final Offering
Memorandum do not, and at the applicable Closing Date, will not, contain any untrue statement
of a material fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not misleading;
provided that the representations and warranties set forth in this Section
4(a) do not apply to statements or omissions made in reliance upon and in conformity with
information relating to the Initial Purchasers furnished to the Company in writing by the
Initial Purchasers expressly for use in the Offering Memorandum. For the purposes of this
Agreement, the only information furnished in writing to the Company by the Initial Purchasers
specifically for use in the Pricing Disclosure Package or the Final Offering Memorandum or any
amendment or supplement thereto is the information set forth in the fifth sentence of the
seventh paragraph and the first sentence of the tenth paragraph under the heading “Plan of
Distribution” in the Offering Memorandum (such information, the “Furnished
Information”). No injunction or order has been issued that either (i) asserts that any of
the transactions contemplated by the Documents is subject to the registration requirements of
the Act or (ii) would prevent or suspend the issuance or sale of any of the Securities or the
use of the Preliminary Offering Memorandum, the Pricing Disclosure Package, the Final Offering
Memorandum or any amendment or supplement thereto, in any jurisdiction. The Pricing
Disclosure Package as of the Applicable Time and each of the Preliminary Offering Memorandum
and the Final Offering Memorandum, as of their respective dates, contained, and the Pricing
Disclosure Package and the Offering Memorandum, as of the applicable Closing Date, will
contain, all the information specified in, and meet the requirements of, Rule 144A(d)(4) under
the Act.

	(b)	 	The Company has not prepared, made, used, authorized, approved or distributed and
will not prepare, make, use, authorize, approve or distribute any written communication that
constitutes an 

-3-

 

	 	 	offer to sell or solicitation of an offer to buy the Securities (each such
communication by the
Company or its agents and representatives (other than a communication referred to in clauses
(i) and (ii) below) a “Company Additional Written Communication”) other than (i) the
Pricing Disclosure Package, (ii) the Final Offering Memorandum, and (iii) any electronic
road show or other written communications, in each case used in accordance with Section
5(c). Each such Company Additional Written Communication, when taken together with the
Pricing Disclosure Package, did not, and at the applicable Closing Date will not, contain
any untrue statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which they were
made, not misleading; provided that this representation, warranty and agreement shall not
apply to statements in or omissions from each such Company Additional Written Communication
made in reliance upon and in conformity with information furnished to the Company in writing
by the Initial Purchasers expressly for use in any Company Additional Written Communication,
if any.

	(c)	 	Each corporation, partnership or other entity in which the Company, directly or
indirectly through any of its subsidiaries, owns more than fifty percent (50%) of any class of
equity securities or interests is listed on Schedule III attached hereto (the
“Subsidiaries”). Each Subsidiary that is a Foreign Restricted Subsidiary (as defined
in the Indenture) has an asterisk (“*”) next to its name on such schedule.

	(d)	 	Each of the Company and its Subsidiaries (i) has been duly organized or formed, as
the case may be, is validly existing and is in good standing under the laws of its
jurisdiction of organization, (ii) has all requisite power and authority to carry on its
business as described in the Pricing Disclosure Package and in the Final Offering Memorandum
and to own, lease and operate its properties and assets as described in the Pricing Disclosure
Package and in the Final Offering Memorandum and (iii) is duly qualified or licensed to do
business and is in good standing as a foreign corporation, partnership, limited liability
company or other entity, as the case may be, authorized to do business in each jurisdiction in
which the nature of such business or the ownership or leasing of such properties requires such
qualification, except where the failure to be so qualified would not, individually or in the
aggregate, have a material adverse effect on (A) the properties, business, operations,
earnings, assets, liabilities or condition (financial or otherwise) of the Company and the
Subsidiaries, taken as a whole, (B) the ability of the Company to perform its obligations in
all material respects under any Document, (C) the validity or enforceability of any of the
Documents or (D) the consummation of the Transactions (each, a “Material Adverse
Effect”).

	(e)	 	All of the issued and outstanding shares of capital stock of or membership interests
in, as the case may be, the Company and the Subsidiaries have been duly authorized and validly
issued, are fully paid and nonassessable, and were not issued in violation of, and are not
subject to, any preemptive or similar rights. The table under the caption “Capitalization” in
the Pricing Disclosure Package and the Final Offering Memorandum (including the footnotes
thereto) sets forth, as of its date, (i) the actual cash and cash equivalents and
capitalization of the Company and the Subsidiaries on a consolidated basis and (ii) the
adjusted cash and cash equivalents and capitalization of the Company and the Subsidiaries, on
a consolidated basis, after giving effect to the offer and sale of the Securities, the
application of the net proceeds therefrom, and the other transactions described in the Pricing
Disclosure Package and the Final Offering Memorandum under the section entitled “Use of
Proceeds.” Except as set forth in such table, immediately following the closing of the
Offering, neither the Company nor any of the Subsidiaries will have any liabilities, absolute,
accrued, contingent or otherwise, other than (A) liabilities that are reflected in the
Financial Statements (as hereinafter defined) or (B) liabilities incurred subsequent to the
date thereof in the ordinary course of business, consistent with past practice, that would
not, individually or in the aggregate, have a Material Adverse Effect. All of the outstanding

-4-

 

	 	 	shares of capital stock or other equity interests of each of the Subsidiaries are owned,
directly or indirectly, by the Company, free and clear of all liens, security interests,
mortgages, pledges,
charges, equities, claims or restrictions on transferability or encumbrances of any kind
(collectively, “Liens”), other than those described in the Pricing Disclosure
Package and the Final Offering Memorandum or imposed by the Act and the securities or “Blue
Sky” laws of certain domestic or foreign jurisdictions. Except as disclosed in the Pricing
Disclosure Package and the Final Offering Memorandum, there are no outstanding (A) options,
warrants or other rights to purchase from the Company or any of the Subsidiaries, (B)
agreements, contracts, arrangements or other obligations of the Company or any of the
Subsidiaries to issue or (C) other rights to convert any obligation into or exchange any
securities for, in the case of each of clauses (A) through (C), shares of capital stock of
or other ownership or equity interests in the Company or any of the Subsidiaries.

	(f)	 	The Company and each of the Subsidiaries that are corporations have the requisite
corporate power and authority, and each of the Subsidiaries that are limited partnerships or
limited liability companies have all the requisite partnership or other power and authority to
execute, deliver and perform their respective obligations under the Documents to which they
are a party and to consummate the Transactions.

	(g)	 	This Agreement has been duly and validly authorized, executed and delivered by the
Company and the Guarantors. The Indenture has been duly and validly authorized by the Company
and the Guarantors. The Indenture, when executed and delivered by the Company and the
Guarantors, will constitute a legal, valid and binding obligation of each of the Company and
the Guarantors, enforceable against each of the Company and the Guarantors in accordance with
its terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency,
reorganization, receivership, moratorium, fraudulent conveyance or other similar laws now or
hereafter in effect relating to creditors’ rights generally and (ii) general principles of
equity (whether applied by a court of law or equity) and the discretion of the court before
which any proceeding therefor may be brought.

	(h)	 	The Securities, when issued, will be in the form contemplated by the Indenture. The
Indenture meets the requirements for qualification under the Trust Indenture Act of 1939, as
amended (the “TIA”). The Securities have each been duly and validly authorized by the
Company and, when delivered to and paid for by the Initial Purchasers in accordance with the
terms of this Agreement and authenticated by the Trustee in accordance with the Indenture,
will have been duly executed, issued and delivered and will be legal, valid and binding
obligations of the Company, entitled to the benefit of the Indenture, enforceable against the
Company in accordance with their terms, except that the enforcement thereof may be subject to
(i) bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors’ rights generally and (ii)
general principles of equity (whether applied by a court of law or equity) and the discretion
of the court before which any proceeding therefor may be brought.

	(i)	 	The Guarantees have been duly and validly authorized by the Guarantors and, when
executed by the Guarantors, will have been duly executed, issued and delivered and will be
legal, valid and binding obligations of the Guarantors, entitled to the benefit of the
Indenture, and enforceable against the Guarantors in accordance with their terms, except that
the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization,
receivership, moratorium, fraudulent conveyance or other similar laws now or hereafter in
effect relating to creditors’ rights generally and (ii) general principles of equity (whether
applied by a court of law or equity) and the discretion of the court before which any
proceeding therefor may be brought.

-5-

 

	(j)	 	Upon issuance and delivery of the Securities in accordance with this Agreement and
the Indenture, the Securities will be convertible at the option of the holder thereof into the
Conversion Shares in accordance with the terms of the Securities and the Conversion Shares
have
been duly reserved for issuance upon conversion of the Securities and have been duly and
validly authorized by the Company and, when issued and delivered to holders of the
Securities upon conversion of the Securities from time to time, the Conversion Shares will
be duly and validly issued, fully paid and nonassessable and will be issued in compliance
with federal and state securities laws. None of the Conversion Shares will be issued in
violation of any preemptive rights, rights of first refusal or other similar rights to
subscribe for or purchase securities of the Company.

	(k)	 	Neither the Company nor any of the Subsidiaries is in violation of its certificate of
incorporation, by-laws or other organizational documents (the “Charter Documents”).
Neither the Company nor any of the Subsidiaries is (i) in violation of any federal, state,
local or foreign statute, law (including, without limitation, common law) or ordinance, or any
judgment, decree, rule, regulation or order (collectively, “Applicable Law”) of any
federal, state, local and other governmental authority, governmental or regulatory agency or
body, court, arbitrator or self-regulatory organization, domestic or foreign (each, a
“Governmental Authority”) applicable to any of them or any of their respective
properties, or (ii) in breach of or default under any bond, debenture, note or other evidence
of indebtedness, indenture, mortgage, deed of trust, lease or any other agreement or
instrument to which any of them is a party or by which any of them or their respective
property is bound (collectively, “Applicable Agreements”), except for such violations,
breaches or defaults that have been irrevocably or permanently waived prior to the date of
this Agreement or that would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. To the knowledge of the Company, there exists no condition
that, with the passage of time or otherwise, would constitute (a) a violation of such Charter
Documents or Applicable Laws, (b) a breach of or default under any Applicable Agreement or (c)
result in the imposition of any penalty or the acceleration of any indebtedness.

	(l)	 	Neither the execution, delivery, issuance or performance of the Documents, as
applicable, nor the consummation of any of the Transactions will conflict with, violate,
constitute a breach of or a default (with the passage of time or otherwise) under, require the
consent of any person (other than consents already obtained and in full force and effect)
under, result in the imposition of a Lien on any assets of the Company or any of its
Subsidiaries or result in an acceleration of indebtedness under or pursuant to (i) the Charter
Documents, (ii) any Applicable Agreement or (iii) any Applicable Law, except for, with respect
to clauses (ii) and (iii), any conflict, violation, breach or default that would not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.
After consummation of the Offering and the Transactions, no Default or Event of Default under
the Indenture will exist.

	(m)	 	When executed and delivered, the Documents will conform in all material respects to
the descriptions thereof in the Pricing Disclosure Package and the Final Offering Memorandum.
Except as disclosed in the Pricing Disclosure Package and the Final Offering Memorandum, there
are no related party transactions that would be required to be disclosed in the Pricing
Disclosure Package and the Final Offering Memorandum if the Pricing Disclosure Package or the
Final Offering Memorandum were a prospectus included in a Registration Statement on Form S-1
filed under the Act.

	(n)	 	No consent, approval, authorization or order of any Governmental Authority or third
party is required for the issuance and sale by the Company of the Securities to the Initial
Purchasers, the issuance of the Conversion Shares or the consummation of the Transactions,
except (i) such as have been obtained and such as may be required under state securities or
“Blue Sky” laws or laws

-6-

 

	 	 	applicable in foreign jurisdictions (in relation to the purchase or
sale of the Securities in such foreign jurisdictions) in connection with the purchase and
resale of the Securities by the Initial Purchasers and the other Transactions, (ii) the
listing of the Conversion Shares on Nasdaq and (iii) the approval of the Company’s
stockholders of the issuance of the Conversion Shares.

	(o)	 	Except as disclosed in the Pricing Disclosure Package and the Final Offering
Memorandum, there is no action, claim, suit, demand, hearing, notice of violation or
deficiency, or proceeding, domestic or foreign (collectively, “Proceedings”), pending
or, to the knowledge of the Company, threatened, that either (i) seeks to restrain, enjoin,
prevent the consummation of or otherwise challenge any of the Documents or any of the
Transactions or (ii) would, individually or in the aggregate, have a Material Adverse Effect.
The Company is not subject to any judgment, order, decree, rule or regulation of any
Governmental Authority that would, individually or in the aggregate, have a Material Adverse
Effect.

	(p)	 	The Company and its Subsidiaries possess all licenses, permits, certificates,
consents, orders, approvals and other authorizations from, and have made all declarations and
filings with, all Governmental Authorities presently required or necessary to own or lease, as
the case may be, and to operate their respective properties and to carry on their respective
businesses as now or proposed to be conducted as described in the Pricing Disclosure Package
and the Final Offering Memorandum (“Permits”), except where the failure to possess
such Permits would not, individually or in the aggregate, have a Material Adverse Effect; each
of the Company and its Subsidiaries has fulfilled and performed all of its obligations with
respect to such Permits and no event has occurred that allows, or after notice or lapse of
time would allow, revocation or termination thereof or results in any other material
impairment of the rights of the holder of any such Permit that would individually or in the
aggregate, have a Material Adverse Effect; and none of the Company or its Subsidiaries has
received any notice of any proceeding relating to the revocation or modification of any such
Permit, except as described in the Pricing Disclosure Package and the Final Offering
Memorandum or except where such revocation or modification would not, individually or in the
aggregate, have a Material Adverse Effect.

	(q)	 	Each of the Company and its Subsidiaries has good and indefeasible title to all real
property owned by it and good title to all personal property owned by it and good title to all
leasehold estates in real and personal property being leased by it and, as of the applicable
Closing Date, all such owned or leased real or personal property will be free and clear of all
Liens (other than Permitted Liens). All Applicable Agreements to which the Company or any of
its Subsidiaries is a party or by which any of them is bound are legal, valid and binding
obligations, other than as disclosed in the Pricing Disclosure Package and the Final Offering
Memorandum, and are enforceable against each of the Company or such Subsidiary, as applicable,
and are enforceable against the other party or parties thereto and are in full force and
effect with only such exceptions as would not, individually or in the aggregate, have a
Material Adverse Effect.

	(r)	 	All Tax returns required to be filed by the Company and each of the Subsidiaries have
been filed and all such returns are true, complete, and correct in all material respects. All
material Taxes that are due from the Company and its Subsidiaries have been paid other than
those (i) currently payable without penalty or interest or (ii) being contested in good faith
and by appropriate proceedings and for which adequate reserves have been established in
accordance with generally accepted accounting principles of the United States, consistently
applied (“GAAP”). To the knowledge of the Company, after reasonable internal inquiry,
there are no actual or proposed Tax assessments against the Company or any of the Subsidiaries
that would, individually or in the aggregate, have a Material Adverse Effect. The accruals and
reserves on the books and records of the Company and its Subsidiaries in respect of any
material Tax liability for any period not finally determined are adequate to meet any
assessments of Tax for any such period. For purposes of this

-7-

 

	 	 	Agreement, the term “Tax” and
“Taxes” shall mean all federal, state, local and foreign taxes, and other assessments of a
similar nature (whether imposed directly or through withholding), including any interest,
additions to tax, or penalties applicable thereto.

	(s)	 	Each of the Company and the Subsidiaries owns, or is licensed under, and has the
right to use, all material patents, patent rights, licenses, inventions, copyrights, know-how
(including trade secrets
and other unpatented and/or unpatentable proprietary or confidential information, systems or
procedures), trademarks, service marks and trade names (collectively, “Intellectual
Property”) necessary for the conduct of its business and, as of the applicable Closing
Date, such Intellectual Property will be free and clear of all Liens other than Permitted
Liens. No claims or notices of any potential claim have been asserted in writing by any
person challenging the use of any such Intellectual Property by the Company or any of the
Subsidiaries or questioning the validity or effectiveness of the Intellectual Property or
any license or agreement related thereto (other than any claims that would not, individually
or in the aggregate, have a Material Adverse Effect). To the knowledge of the Company, the
use of such Intellectual Property by the Company or any of the Subsidiaries will not
infringe on the Intellectual Property rights of any other person.

	(t)	 	The Company maintains a system of internal accounting controls sufficient to provide
reasonable assurance that (i) material transactions are executed in accordance with
management’s general or specific authorization, (ii) material transactions are recorded as
necessary to permit preparation of financial statements in conformity with GAAP, and to
maintain asset accountability, (iii) access to assets is permitted only in accordance with
management’s general or specific authorization and (iv) the recorded accountability for assets
is compared with the existing assets at reasonable intervals and appropriate action is taken
with respect to any material differences. The Company’s independent auditors and board of
directors have been advised of: (i) all significant deficiencies, if any, in the design or
operation of internal controls which could adversely affect the Company’s ability to record,
process, summarize and report financial data and (ii) all fraud, if any, whether or not
material, that involves management or other employees who have a role in the Company’s
internal controls; all material weaknesses, if any, in internal controls have been identified
to the Company’s independent auditors; since the date of the most recent evaluation of such
disclosure controls and procedures and internal controls, there have been no significant
changes in internal controls or in other factors that could significantly affect internal
controls, including any corrective actions with regard to significant deficiencies and
material weaknesses; the principal executive officers (or their equivalents) and principal
financial officers (or their equivalents) of the Company have made all certifications required
by the Sarbanes-Oxley Act of 2002, as amended, including the rules and regulations promulgated
thereunder, and the statements contained in each such certification are complete and correct.

	(u)	 	The Company and the Subsidiaries maintain an effective system of “disclosure controls
and procedures” (as defined in Rule 13a-15(e) of the Exchange Act) that is designed to ensure
that information required to be disclosed by the Company in reports that it files or submits
under the Exchange Act is recorded, processed, summarized and reported within the time periods
specified in the Commission’s rules and forms, including controls and procedures designed to
ensure that such information is accumulated and communicated to the Company’s management as
appropriate to allow timely decisions regarding required disclosure. The Company and the
Subsidiaries have carried out evaluations of the effectiveness of their disclosure controls
and procedures as required by Rule 13a-15 of the Exchange Act.

	(v)	 	The audited consolidated financial statements and related notes of the Company
contained in the Pricing Disclosure Package and the Final Offering Memorandum (the
“Financial Statements”) present fairly the consolidated financial position, results of
operations and cash flows of the Company and its consolidated Subsidiaries as of the
respective dates and for the respective

-8-

 

	 	 	periods to which they apply and have been prepared in
accordance with United States GAAP and the requirements of Regulation S-X of the Act. The
financial data set forth under “Summary Selected Financial Data” included in the Pricing
Disclosure Package and the Final Offering Memorandum has been prepared on a basis consistent
with that of the Financial Statements and present fairly the consolidated financial position
and results of operations of the Company as of the respective dates and for the respective
periods indicated. All other financial, statistical, market and industry-related data
included in the Pricing Disclosure Package and the Final
Offering Memorandum are fairly and accurately presented in all material respects and are
based on or derived from sources that the Company believes to be reliable and accurate.

	(w)	 	Subsequent to the respective dates as of which information is given in the Pricing
Disclosure Package and the Final Offering Memorandum, except as disclosed in the Pricing
Disclosure Package and the Final Offering Memorandum, (i) neither the Company nor any of the
Subsidiaries has incurred any liabilities, direct or contingent, that are material,
individually or in the aggregate, to the Company, or has entered into any transactions not in
the ordinary course of business, (ii) there has not been any material decrease in the capital
stock or any material increase in long-term indebtedness or any material increase in
short-term indebtedness of the Company or any payment of or declaration to pay any dividends
or any other distribution with respect to the Company, and (iii) there has not been any
material adverse change, or development involving a prospective material adverse change, in
the properties, business, operations, earnings, assets, liabilities or condition (financial or
otherwise) of the Company and the Subsidiaries taken as a whole in the aggregate (each of
clauses (i), (ii) and (iii), a “Material Adverse Change”). To the knowledge of the
Company after reasonable internal inquiry, there is no event that is reasonably likely to
occur, which would, individually or in the aggregate, have a Material Adverse Effect except as
disclosed in the Pricing Disclosure Package and the Final Offering Memorandum.

	(x)	 	No “nationally recognized statistical rating organization” (as such term is defined
for purposes of Rule 436(g)(2) under the Act) (i) has imposed (or has informed the Company
that it is considering imposing) any condition (financial or otherwise) on the Company
retaining any rating assigned to the Company or any of the Subsidiaries or to any securities
of the Company or any of the Subsidiaries, or (ii) has indicated to the Company that it is
considering (A) the downgrading, suspension, or withdrawal of, or any review for a possible
change that does not indicate the direction of the possible change in, any rating so assigned,
or (B) any negative change in the outlook for any rating of the Company or any of the
Subsidiaries or any securities of the Company or any of the Subsidiaries.

	(y)	 	All indebtedness represented by the Securities is being incurred in good faith and
for the purposes set forth in the “Use of Proceeds” section of the Pricing Disclosure Package
and the Final Offering Memorandum. On the applicable Closing Date, after giving pro forma
effect to the Offering and the use of proceeds therefrom as indicated in the “Use of Proceeds”
section of the Pricing Disclosure Package and the Final Offering Memorandum, the Company and
the Guarantors, on a consolidated basis (i) will be Solvent (as hereinafter defined), (ii)
will have sufficient capital for carrying on its business and (iii) will be able to pay its
debts as they mature. As used in this paragraph, the term “Solvent” means, with respect to a
particular date, that on such date (i) the present fair market value (or present fair saleable
value) of the assets of the Company and each Guarantor is not less than the total amount
required to pay the liabilities of the Company and each Guarantor on its total existing debts
and liabilities (including contingent liabilities) as they become absolute and matured; (ii)
the Company and each Guarantor is able to pay its debts and other liabilities, contingent
obligations and commitments as they mature and become due in the normal course of business;
(iii) assuming consummation of the issuance of the Securities as contemplated by this
Agreement and the Pricing Disclosure Package and the Final Offering Memorandum, neither the
Company nor any Guarantor is incurring debts or liabilities

-9-

 

	 	 	beyond its ability to pay as such
debts and liabilities mature; (iv) neither the Company nor any Guarantor is engaged in any
business or transaction, and does not propose to engage in any business or transaction, for
which its property would constitute unreasonably small capital after giving due consideration
to the prevailing practice in the industry in which the Company or any Guarantor is engaged;
and (v) neither the Company nor any Guarantor is otherwise insolvent under the standards set
forth in applicable laws.

	(z)	 	The Company has not and, to its knowledge after reasonable internal inquiry, no one
acting on its behalf (excluding for such purposes, the Initial Purchasers) has, (i) taken,
directly or indirectly, any action designed to cause or to result in, or that has constituted
or that might reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of any of the
Securities, (ii) sold, bid for, purchased, or paid anyone any compensation for soliciting
purchases of, any of the Securities, or (iii) except as disclosed in the Pricing Disclosure
Package and the Final Offering Memorandum, paid or agreed to pay to any person any
compensation for soliciting another to purchase any other securities of the Company.

	(aa)	 	Assuming (i) the accuracy of the representations contained in Section 6 hereof
(including, without limitation, the accuracy of the Initial Purchasers’ representations
contained herein regarding the absence of general solicitation in connection with the sale of
the Securities to the Initial Purchasers and in the Exempt Resales) and (ii) that the
purchasers in the Exempt Resales are QIBs or non-U.S. persons (as defined under Regulation S
of the Act), no registration under the Act and no qualification of the Indenture under the TIA
is required for the sale of the Securities to the Initial Purchasers as contemplated hereby or
for the Exempt Resales.

	(bb)	 	Assuming the accuracy of the representations contained in Section 6 hereof, the
Securities are eligible for resale pursuant to Rule 144A under the Act and no other securities
of the Company are of the same class (within the meaning of Rule 144A under the Act) as the
Securities and listed on a national securities exchange registered under Section 6 of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), or quoted in a U.S.
automated inter-dealer quotation system. No securities of the Company of the same class as
the Securities or the Conversion Shares have been offered, issued or sold by the Company or
any of its respective affiliates within the six-month period immediately prior to the date
hereof.

	(cc)	 	The shares of Common Stock are registered pursuant to Section 12b of the Exchange
Act and are listed on The Nasdaq Global Select Market (“Nasdaq”), and the Company has
taken no action designed to, or likely to have the effect of, terminating the registration of
the shares of Common Stock under the Exchange Act or delisting the shares of Common Stock from
Nasdaq. Except as described in the Company’s periodic filings under the Exchange Act
incorporated by reference in the Pricing Disclosure Package or Final Offering Memorandum, the
Company has not received any notification that the SEC or Nasdaq is contemplating terminating
such registration or listing.

	(dd)	 	Neither of the Company nor any of its affiliates or other person acting on behalf of
the Company has offered or sold the Securities by means of any general solicitation or general
advertising within the meaning of Rule 502(c) under the Act or, with respect to Securities
sold outside the United States to non-U.S. persons (as defined in Rule 902 under the Act), by
means of any directed selling efforts within the meaning of Rule 902 under the Act, and the
Company, any affiliate of the Company and any person acting on behalf of the Company have
complied with and will implement the “offering restrictions” within the meaning of such Rule
902; provided, that no representation is made in this subsection with respect to the
actions of the Initial Purchasers.

-10-

 

	(ee)	 	Except as disclosed in the Pricing Disclosure Package and the Final Offering
Memorandum, each of the Company, the Subsidiaries, and each ERISA Affiliate has fulfilled its
obligations, if any, under the minimum funding standards of Section 302 of the United States
Employee Retirement Income Security Act of 1974, as amended (“ERISA”) with respect to
each “pension plan” (as defined in Section 3(2) of ERISA), subject to Section 302 of ERISA
that the Company, the Subsidiaries or any ERISA Affiliate sponsors or maintains, or with
respect to which it has (or within the last three years had) any obligation to make
contributions, and each such plan is in compliance in all material respects with the presently
applicable provisions of ERISA and the
Internal Revenue Code of 1986, as amended (the “Code”), in each case, except as
would not, individually or in the aggregate, have a Material Adverse Effect. Except as
disclosed in the Pricing Disclosure Package and the Final Offering Memorandum, neither the
Company, the Subsidiaries, nor any ERISA Affiliate has incurred any unpaid liability to the
Pension Benefit Guaranty Corporation (other than for the payment of premiums in the ordinary
course) or to any such plan under Title IV of ERISA. “ERISA Affiliate” means a
corporation, trade or business that is, along with the Company or any Subsidiary, a member
of a controlled group of corporations or a controlled group of trades or businesses, as
described in Section 414 of the Code or Section 4001 of ERISA.

	(ff)	 	Other than as disclosed in the Pricing Disclosure Package and the Final Offering
Memorandum, (i) neither the Company nor any of the Subsidiaries is party to or bound by any
collective bargaining agreement with any labor organization; (ii) none of the employees of the

Company’s knowledge, no union organizing or decertification efforts are underway or threatened
against the Company or the Subsidiaries; (iv) no labor strike, work stoppage, slowdown, or
other material labor dispute is pending against the Company or the Subsidiaries, or, to the
knowledge of the Company, after reasonable internal inquiry, threatened against the Company or
the Subsidiaries; (v) there is no worker’s compensation liability, experience or matter that

(vii) there is no employment-related charge, complaint, grievance, investigation, unfair labor
practice claim, or inquiry of any kind, pending against the Company or the Subsidiaries that
could, individually or in the aggregate, have a Material Adverse Effect; (viii) to the
knowledge of the Company, after reasonable internal inquiry, no employee or agent of the

violation identified in subsection (vi) and (vii) above, other than such acts or omissions
that would not, individually or in the aggregate, have a Material Adverse Effect; and (ix) no
term or condition of employment exists through arbitration awards, settlement agreements, or
side agreement that is contrary to the express terms of any applicable collective bargaining
agreement.

	(gg)	 	None of the Transactions or the application by the Company or any of the
Subsidiaries of the proceeds of the Securities will violate or result in a violation of
Section 7 of the Exchange Act, (including, without limitation, Regulation T (12 C.F.R. Part
220), Regulation U (12 C.F.R. Part 221) or Regulation X (12 C.F.R. Part 224) of the Board of
Governors of the Federal Reserve System).

	(hh)	 	Neither the Company nor any of the Subsidiaries is an open-end investment company,
unit investment trust or face-amount certificate company that is or is required to be
registered under Section 8 of the United States Investment Company Act of 1940 (the
“Investment Company Act”); and neither the Company nor any of the Subsidiaries, after
giving effect to the Offering

-11-

 

	 	 	and sale of the Securities and the application of the proceeds
thereof as described in the Pricing Disclosure Package and the Final Offering Memorandum, will
be an “investment company” as defined in the Investment Company Act.

	(ii)	 	The Company has not engaged any broker, finder, commission agent or other person
(other than the Initial Purchasers) in connection with the Offering or any of the transactions
contemplated in the Documents, and the Company is not under any obligation to pay any broker’s
fee or commission in connection with such transactions (other than commissions or fees to the
Initial Purchasers).

	(jj)	 	Each of the Company and the Subsidiaries is (i) in compliance with any and all
applicable foreign, provincial, federal, state and local laws and regulations relating to
health and safety, or the pollution or the protection of the environment or hazardous or toxic
substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) has
received and is in compliance with all permits, licenses or other approvals required of them
under applicable Environmental Laws to conduct its respective businesses and (iii) has not
received notice of, and is not aware of, any actual or potential liability for damages to
natural resources or the investigation or remediation of any disposal, release or existence of
hazardous or toxic substances or wastes, pollutants or contaminants, in each case except where
such non-compliance with Environmental Laws, failure to receive and comply with required
permits, licenses or other approvals, or liability would not, individually or in the
aggregate, have a Material Adverse Effect. Neither the Company nor any of the Subsidiaries
has been named as a “potentially responsible party” under the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended, or any similar state or local
or foreign or provincial Environmental Laws or regulations requiring the Company or any of its
Subsidiaries to investigate or remediate any pollutants or contaminants, except where such
requirements would not, individually or in the aggregate, have a Material Adverse Effect,
whether or not arising from transactions in the ordinary course of business.

	(kk)	 	In the ordinary course of its business, the Company periodically reviews the effects
of Environmental Laws on the business, operations and properties of the Company and the
Subsidiaries, in the course of which it identifies and evaluates associated costs and
liabilities (including, without limitation, any capital or operating expenditures required for
clean-up, closure of properties or compliance with Environmental Laws, or any permit, license
or approval, any related constraints on operating activities and any potential liabilities to
third parties). On the basis of such review and the indemnification for certain costs and
liabilities that the Company or its Subsidiaries is entitled to receive from the Company’s
former parent company, the Company has reasonably concluded that such associated costs would
not, individually or in the aggregate, have a Material Adverse Effect on the Company’s
business, operations or earnings.

	 	 	The Company reviewed the effects of Environmental Laws on the business, operations and
properties of the Company and the Subsidiaries, and has identified and evaluated associated
costs and liabilities (including, without limitation, any capital or operating expenditures
required for clean-up, closure of properties or compliance with Environmental Laws, or any
permit arising from the Company’s or its Subsidiaries’ or any predecessors’ or formerly
owned or operated properties or license or approval, any related constraints on operating
activities and any potential liabilities to third parties). Based on such review, the
Company has reasonably concluded that such associated costs and liabilities would not,
individually or in the aggregate, have a Material Adverse Effect on the Company’s business,
operations or earnings.

	(ll)	 	As of the applicable Closing Date, except as provided in the Credit Agreement and
the Indenture and as disclosed in the Pricing Disclosure Package and the Final Offering
Memorandum, as of the applicable Closing Date, there will be no encumbrances or restrictions
(other than under 

-12-

 

	 	 	
applicable law) on the ability of any Subsidiary of the Company (x) to pay
dividends or make other distributions on such Subsidiary’s capital stock or to pay any
indebtedness to the Company or any other Subsidiary of the Company, (y) to make loans or
advances or pay any indebtedness to, or investments in, the Company or any other Subsidiary of
the Company or (z) to transfer any of its property or assets to the Company or any other
Subsidiary of the Company.

	(mm)	 	Each certificate signed by any officer of the Company, or any Subsidiary thereof,
delivered to the Initial Purchasers shall be deemed a representation and warranty by the
Company or any such Subsidiary thereof (and not individually by such officer) to the Initial
Purchasers with respect to the matters covered thereby.

	(nn)	 	Each of the Company and its Subsidiaries is insured by insurers of recognized
financial responsibility against such losses and risks and in such amounts as are prudent and
customary in the businesses in which they are engaged. All policies of insurance insuring the
Company or any of its Subsidiaries or their respective businesses, assets, employees, officers
and directors are in full force and effect. The Company and the Subsidiaries are in
compliance with the terms of such policies and instruments in all material respects, and there
are no material claims by the Company or any of the Subsidiaries under any such policy or
instrument as to which any insurance company is denying liability or defending under a
reservation of rights clause. Neither the Company nor any such Subsidiary has been refused
any insurance coverage sought or applied for, and neither the Company nor any such Subsidiary
has any reason to believe that it will not be able to renew its existing insurance coverage as
and when such coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not, individually or in the aggregate,
have a Material Adverse Effect.

	(oo)	 	There is and has been no failure on the part of the Company and the Subsidiaries or
any of the officers and directors of the Company or any of the Subsidiaries, in their
capacities as such, to comply in all material respects with the applicable provisions of The
Sarbanes-Oxley Act of 2002 and the rules and regulations in connection therewith.

	(pp)	 	(i) The Company has established and maintains “disclosure controls and procedures”
(as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) and (ii) the Company’s
“disclosure controls and procedures” are reasonably designed to ensure that all information
(both financial and non-financial) required to be disclosed by the Company in the reports that
it files or submits under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in the rules and regulations thereunder, and that all such
information is accumulated and communicated to the Company’s management as appropriate to
allow timely decisions regarding required disclosure and to make the certifications of the
Chief Executive Officer and Chief Financial Officer of the Company required under the Exchange
Act with respect to such reports.

	(qq)	 	Ernst & Young LLP, the accountants who audited the 2008 financial statements
incorporated by reference in the Pricing Disclosure Package and the Final Offering Memorandum
and Deloitte & Touche LLP, the Company’s independent registered public accounting firm as of
March 20, 2009, who audited the 2009 and 2010 financial statements incorporated by reference
in the Pricing Disclosure Package and the Final Offering Memorandum are independent public
accountants as required by the Act and the regulations promulgated under the Act and the
Exchange Act and the rules and regulations of the Public Company Accounting Oversight Board.

	(rr)	 	No forward-looking statement (within the meaning of Section 27A of the Act and
Section 21E of the Exchange Act) or presentation of market-related or statistical data
contained in the Pricing Disclosure Package or the Final Offering Memorandum has been made or
reaffirmed without a reasonable basis or has been disclosed in other than good faith.

	(ss)	 	The Company has not taken or omitted to take any action and will not take any action
or omit to take any action (such as issuing any press release or making any other public
announcement referring to the Offering without an appropriate stabilization legend) which may
result in the loss by the Initial Purchasers of the ability to rely on any stabilization safe
harbour provided by the Financial Services Authority of the United Kingdom under the Financial
Services and Markets Act 2000 (the “FSMA”); such representation and warranty only to
apply if any such stabilization safe harbor is, or was to become, applicable to the issuance
of the Notes and on the basis that at the date of this Agreement no such safe harbor is
available; provided, however, that an appropriate stabilization legend was not in the
Preliminary Offering Memorandum or the Pricing Term Sheet. The Company has been informed of
the guidance relating to stabilization provided
by the Financial Services Authority of the United Kingdom, in particular the guidance
contained in Section MAR 2 of the Financial Services Handbook.

	(tt)	 	Neither the Company nor, to the knowledge of the Company, any director, officer,
agent, employee or Subsidiary of the Company is aware of or has taken any action, directly or
indirectly, that would result in a violation by such persons of the U.S. Foreign Corrupt
Practices Act of 1977, as amended, and the rules and regulations thereunder (the
“FCPA”), including, without limitation, making use of the mails or any means or
instrumentality of U.S. interstate commerce corruptly in furtherance of an offer, payment,
promise to pay or authorization of the payment of any money, or other property, gift, promise
to give, or authorization of the giving of anything of value to any “foreign official” (as
such term is defined in the FCPA) or any foreign political party or official thereof or any
candidate for foreign political office, in contravention of the FCPA; and the Company and its
Subsidiaries have conducted their businesses in compliance in all material respects with the
FCPA and have instituted and maintain policies and procedures designed to ensure, and which
are reasonably expected to continue to ensure, continued compliance therewith.

	(uu)	 	The Company is subject to and is in full compliance in all material respects with
the reporting requirements of Section 13 and Section 15(d), as applicable, of the Exchange
Act.

	(vv)	 	There are no stamp or other issuance or transfer taxes or duties or other similar
fees or charges required to be paid in connection with the execution and delivery of this
Agreement on the issuance or sale by the Company of the Notes.

	(ww)	 	The Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010
and all subsequent documents filed under Sections 13(a), 13(c), 14 or 15(d) of the Exchange
Act filed after the date of this Agreement, incorporated by reference into the Pricing
Disclosure Package and the Final Offering Memorandum (the “Incorporated Information”),
complies or will comply in all material respects with all applicable requirements of the
Exchange Act, including the rules and regulations promulgated thereunder, and the Incorporated
Information does not and will not (as amended or supplemented, if amended or supplemented)
contain any untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements therein, in the light of circumstances under which they were
made, not misleading.

	(xx)	 	The operations of the Company and the Subsidiaries are and have been conducted at
all times in compliance with applicable financial recordkeeping and reporting requirements of
the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering
statutes of all applicable jurisdictions, the rules and regulations thereunder and any related
or similar rules, regulations or guidelines issued, administered or enforced by any
governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or
proceeding by or before any court or governmental agency, authority or body or any arbitrator
involving the Company or the

	 	 	Subsidiaries with respect to the Money Laundering Laws is pending
or, to the best knowledge of the Company, threatened.

	(yy)	 	Neither the Company nor the Subsidiaries nor, to the knowledge of the Company, any
director, officer, agent, employee or affiliate of the Company or the Subsidiaries is
currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control
of the U.S. Treasury Department (“OFAC”); and the Company will not directly or
indirectly use the proceeds of the offering, or lend, contribute or otherwise make available
such proceeds to any subsidiary, joint venture partner or other person or entity, for the
purpose of financing the activities of any person currently subject to any U.S. sanctions
administered by OFAC.

	(zz)	 	Each of the Company’s directors and executive officers listed in Exhibit D
has executed and delivered to the Representatives a lock-up agreement in the form of
Exhibit B hereto (a “Lock-up Agreement”). Exhibit D hereto contains a
true, complete and correct list of all directors and officers of the Company. All directors
and executive officers who are required pursuant to this Agreement to execute and deliver a
Lock-up Agreement are collectively hereinafter referred to as the “Locked-up Persons.”

          5. Covenants of the Company and the Guarantors. Each of the Company and the
Guarantors jointly and severally agrees:

	(a)	 	To (i) advise the Initial Purchasers promptly after obtaining knowledge (and, if
requested by the Initial Purchasers, confirm such advice in writing) of (A) the issuance by
any state securities commission of any stop order suspending the qualification or exemption
from qualification of any of the Securities for offer or sale in any jurisdiction, or the
initiation of any proceeding for such purpose by any state securities commission or other
regulatory authority, or (B) the happening of any event that makes any statement of a material
fact made in the Pricing Disclosure Package, any Company Additional Written Communication, or
the Final Offering Memorandum, untrue or that requires the making of any additions to or
changes in the Pricing Disclosure Package, any Company Additional Written Communication, or
the Final Offering Memorandum, in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, (ii) use its commercially reasonable
efforts to prevent the issuance of any stop order or order suspending the qualification or
exemption from qualification of any of the Securities under any state securities or Blue Sky
laws, and (iii) if, at any time, any state securities commission or other regulatory authority
shall issue an order suspending the qualification or exemption from qualification of any of
the Securities under any such laws, use its commercially reasonable efforts to obtain the
withdrawal or lifting of such order at the earliest possible time.

	(b)	 	To (i) furnish the Initial Purchasers, without charge, with as many copies of the
Preliminary Offering Memorandum, the Pricing Disclosure Package and the Final Offering
Memorandum, and any amendments or supplements thereto, as the Initial Purchasers may

Memorandum, and any amendments and supplements thereto, by the Initial Purchasers in
connection with Exempt Resales).

	(c)	 	Not to amend or supplement the Pricing Disclosure Package or the Final Offering

provided their written consent thereto. Before making, preparing, using, authorizing,
approving or referring to any Company Additional Written Communications, the Company will
furnish to the Initial Purchasers and counsel for the Initial Purchasers a copy of such
written communication for review and will not make, prepare, use, authorize, approve or refer
to any such written communication to which the Initial Purchasers reasonably object.

	(d)	 	So long as the Initial Purchasers shall hold any of the Securities, (i) if any event
shall occur as a result of which, in the reasonable judgment of the Company or the Initial
Purchasers, it becomes necessary or advisable to amend or supplement the Pricing Disclosure
Package or the Final Offering Memorandum in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading, or if it is necessary to
amend or supplement the
Pricing Disclosure Package or the Final Offering Memorandum to comply with Applicable Law,
to prepare, at the expense of the Company, an appropriate amendment or supplement to the
Pricing Disclosure Package and the Final Offering Memorandum (in form and substance
reasonably satisfactory to the Initial Purchasers) so that (A) as so amended or

include an untrue statement of material fact or omit to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under which they
were made, not misleading, and (B) the Pricing Disclosure Package and the Final Offering
Memorandum will comply with Applicable Law and (ii) if in the reasonable judgment of the
Company it becomes necessary or advisable to amend or supplement the Pricing Disclosure
Package or the Final Offering Memorandum so that the Pricing Disclosure Package and the

show” undertaken in connection with the marketing of the offering of the Securities; provided
that in no event shall the Company be responsible for the fees, disbursements or out-of-pocket
expenses of counsel to the Initial Purchasers. If the sale of the Securities provided for
herein is not consummated because any condition to the obligations of the Initial Purchasers
set forth in Section 7 is not satisfied, because this Agreement is terminated pursuant to
Section 9 or because of any failure, refusal or inability on the part of the Company to
perform all obligations and satisfy all conditions on its part to be performed or satisfied
hereunder (other than in each case solely by reason of a default by the Initial Purchasers on
its obligations hereunder after all conditions hereunder have been satisfied in accordance

fees, disbursements and out-of-pocket expenses, travel and lodging expenses, word processing
charges,
messenger and duplicating services, facsimile expenses and other reasonable and customary

Securities in a manner that would require the registration under the Act of the sale to the
Initial Purchasers or to the Subsequent Purchasers of the Securities.

	(j)	 	For so long as any of the Securities remain outstanding, during any period in which
the Company is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon

prospective Subsequent Purchasers of such Securities from such owner, the information required

of the Act or (iii) engage in any directed selling efforts within the meaning of Regulation S,
and all such persons will comply with the offering restrictions requirement of Regulation S.

	(n)	 	During the one year period after the Initial Closing Date, to not, and to not permit
any current or future Subsidiaries of either the Company or any other affiliates (as defined
in Rule 144A under the Act) controlled by the Company to, resell any of the Securities which
constitute “restricted securities” under Rule 144 that have been reacquired by the Company,
any current or future Subsidiaries or any other “affiliates” (as defined in Rule 144A under
the Act) controlled by the Company, except pursuant to an effective registration statement

Representatives a Lock-up Agreement.

	(t)	 	Except as provided for in Section 3(c), the Company will not, during the period
ending 90 days after the Initial Closing Date (as the same may be extended as described below,
the “Company Lock-up Period”), without the prior written consent of the Representatives (which
consent may be withheld at the sole discretion of the Representatives), directly or
indirectly, sell (including, without limitation, any short sale), offer, contract or grant any
option to sell, pledge, transfer or establish an open “put equivalent position” within the
meaning of Rule 16a-1(h) under the Exchange Act, or enter into any swap or other agreement
that transfers, in whole or in part, any of the economic consequences of ownership of any
shares of Common Stock or any such other securities, or otherwise dispose of or transfer, or
announce the offering of, or file any registration statement under the Act in respect of, any
shares of Common Stock, options, rights or warrants to acquire shares of Common Stock or

issue shares of Common Stock or options to purchase shares of Common Stock, or issue shares of
Common Stock upon exercise of options, pursuant to any stock option, stock bonus or other

sell, offer, dispose of or otherwise transfer any such shares or options during such Company
Lock-up Period without the prior written consent of the Representatives (which consent may be
withheld at the sole discretion of the Representatives). Notwithstanding the foregoing, if
(i) during the last 17 days of the Company Lock-up Period, the Company issues an earnings
release or material news or a material event relating to the Company occurs and is publicly
disclosed or otherwise becomes publicly known or (ii) prior to the expiration of the Company
Lock-up Period, the Company announces that it will release earnings results during the 16-day
period beginning on the last day of the Company Lock-up Period, then in each case the Company
Lock-up Period will be extended until the expiration of the 18-day period beginning on the
date of the issuance of the earnings release or the occurrence of the
material news or material event, as applicable, unless the Representatives waive, in
writing, such extension (which waiver may be withheld at the sole discretion of the
Representatives), except that such extension will not apply if, (i) within three business
days prior to the 15th calendar day before the last day of the Company Lock-up Period, the
Company delivers a certificate, signed by the Chief Financial Officer or Chief Executive
Officer of the Company, certifying on behalf of the Company that (i) the Conversion Shares
are “actively traded securities” (as defined in Regulation M), (ii) the Company meets the
applicable requirements of paragraph (a)(1) of Rule 139 under the Securities Act in the
manner contemplated by NASD Conduct Rule 2711(f)(4), and (iii) the provisions of NASD
Conduct Rule 2711(f)(4) are not applicable to any research reports relating to the Company
published or distributed by any of the Initial Purchasers during the 15 days before or after
the last day of the Company Lock-up Period (before giving effect to such extension). The
Company will provide the Representatives with prior notice of any such announcement that
gives rise to an extension of the Company Lock-up Period.

          6. Representations and Warranties of the Initial Purchasers. Each of the Initial
Purchasers represents and warrants, severally and not jointly, that:

to in Regulation S under the Act and in compliance with laws applicable to such persons in
jurisdictions outside of the United States; provided, however, that in
purchasing such Securities, such persons are deemed to have represented and agreed as provided
under the caption “Notice to Investors” contained in the Pricing Disclosure Package and the
Final Offering Memorandum.

	(c)	 	No form of general solicitation or general advertising in violation of the Act has
been or will be used nor will any offers in any manner involving a public offering within the
meaning of Section 4(2) of the Act or, with respect to Securities to be sold in reliance on
Regulation S, by means of any directed selling efforts be made by such Initial Purchaser or
any of its representatives in connection with the offer and sale of any of the Securities.

or complied with all of the agreements and satisfied all conditions on their respective parts

issuance or marketability of the Securities, and (ii) would not, individually or in the
aggregate, have a Material Adverse Effect.
	 
	(d)	 	Subsequent to the respective dates as of which data and information is given in the

and the Final Offering Memorandum.
	 
	(e)	 	On or after the date hereof and on or prior to the applicable Closing Date, (i) there

of the Company (including, without limitation, the placing of any of the foregoing ratings on
credit watch with negative or developing implications or under review with an uncertain
direction) by any “nationally recognized statistical rating organization” as such term is
defined for purposes of Rule 436(g)(2) under the Act, (ii) there shall not have occurred any
negative change, nor shall any notice have been given of any potential or intended negative
change, in the outlook for any rating of the Company or any securities of the Company by any

each person, if any, who controls the Initial Purchasers within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities
of any kind to which the Initial Purchasers, their affiliates, directors, officers and
employees or such controlling persons may become subject under the Act, the Exchange Act or
other federal or state statutory law or regulation, or at common law or otherwise (including
in settlement of any litigation, if such settlement is effected with the written consent of
the Company (not to be unreasonably withheld, delayed or conditioned), insofar as any such
losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are
based upon:

-22-

 

	 	(i)	 	any untrue statement or alleged untrue statement of a material fact contained
in the Preliminary Offering Memorandum, the Pricing Disclosure Package, any Company
Additional Written Communication or the Final Offering Memorandum (or any amendment or
supplement thereto);
	 
	 	(ii)	 	the omission or alleged omission to state, in the Preliminary Offering
Memorandum the Pricing Disclosure Package, any Company Additional Written Communication
or the Final Offering Memorandum (or any amendment or supplement thereto), a material
fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading; or
	 
	 	(iii)	 	any breach by the Company or any of the Guarantors of their respective
representations, warranties and agreements set forth herein or breach of applicable
law;

	 	 	and, subject to the provisions hereof, will reimburse, as incurred, the Initial Purchasers,
their affiliates, directors, officers, employees and each such controlling person for any
legal or other expenses incurred by the Initial Purchasers or such controlling person in
connection with investigating, defending against or appearing as a third-party witness in
connection with any such loss, claim, damage, liability or action in respect thereof;
provided, however, the Company and the Guarantors will not be liable in any
such case to the extent (but only to the extent) that a court of competent jurisdiction
shall have determined by a final, unappealable judgment that such loss, claim, damage or
liability resulted solely from any untrue statement or alleged untrue statement or omission
or alleged omission made in the Preliminary Offering Memorandum, the Pricing Disclosure
Package, any Company Additional Written Communication or the Final Offering Memorandum or
any amendment or supplement thereto in reliance upon and in conformity with the Furnished
Information. This indemnity agreement will be in addition to any liability that the
Company and the Guarantors may otherwise have to the indemnified parties.

	(b)	 	Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold
harmless each of the Company and the Guarantors and their respective directors, officers and
each person, if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the
Company or any such director, officer or controlling person may become subject under the Act,
the Exchange Act or otherwise, insofar as a court of competent jurisdiction shall have
determined by a final, unappealable judgment that such losses, claims, damages or liabilities
(or actions in respect thereof) have resulted solely from (i) any untrue statement or alleged
untrue statement of any material fact contained in any Offering Memorandum or any amendment or
supplement thereto or (ii) the omission or the alleged omission to state therein a material
fact required to be stated in any Offering Memorandum or any amendment or supplement thereto
or necessary to make the statements therein not misleading, in each case to the extent (but
only to the extent) that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with the Furnished Information
furnished by such Initial Purchaser; and, subject to the limitation set forth immediately
preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by
the Company, each of the Guarantors or any such director, officer or controlling person in
connection with any such loss, claim, damage, liability or action in respect thereof. Each of
the Company and the Guarantors hereby acknowledges that the only information that the Initial
Purchasers have furnished to the Company or its agents specifically for use in the Preliminary
Offering Memorandum or the Final Offering Memorandum or any amendment or supplement thereto,
is the Furnished Information. This indemnity agreement will be in addition to any liability
that the Initial Purchasers may otherwise have to the indemnified parties.

-23-

 

	(c)	 	As promptly as reasonably practicable after receipt by an indemnified party under
this Section 8 of notice of the commencement of any action for which such indemnified party is
entitled to indemnification under this Section 8, such indemnified party will, if a claim in
respect thereof is to be made against the indemnifying party under this Section 8, notify the
indemnifying party of the commencement thereof in writing; but the omission to so notify the
indemnifying party (i) will not relieve such indemnifying party from any liability under
paragraph (a) or (b) above unless and only to the extent it is materially prejudiced as a
result thereof and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation provided in
paragraphs (a) and (b) above. In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may elect, jointly
with any other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party; provided, however,
that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest, (ii) the defendants in any such
action include both the indemnified party and the indemnifying party, and the indemnified
party shall have concluded that a conflict may arise between the positions of the indemnifying
party and the indemnified party in conducting the defense of any such action or that there may
be one or more legal defenses available to it and/or other indemnified parties that are
different from or additional to those available to the indemnifying party or (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified
party to represent the indemnified party within a reasonable time after receipt by the
indemnifying party of notice of the institution of such action, then, in each such case, the
indemnifying party shall not have the right to direct the defense of such action on behalf of
such indemnified party or parties and such indemnified party or parties shall have the right
to select separate counsel to defend such action on behalf of such indemnified party or
parties at the expense of the indemnifying party. After notice from the indemnifying party to
such indemnified party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying party will not
be liable to such indemnified party under this Section 8 for any legal or other expenses,
other than reasonable costs of investigation, subsequently incurred by such indemnified party
in connection with the defense thereof, unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the immediately preceding sentence (it
being understood, however, that in connection with such action the indemnifying party shall
not be liable for the expenses of more than one separate counsel (in addition to local
counsel) in any one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances, designated by the
Initial Purchasers in the case of paragraph (a) of this Section 8 or the Company in the case
of paragraph (b) of this Section 8, representing the indemnified parties under such paragraph
(a) or paragraph (b), as the case may be, who are parties to such action or actions), (ii) the
indemnifying party has authorized in writing the employment of counsel for the indemnified
party at the expense of the indemnifying party or (iii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action, in each of which cases
the fees and expenses of counsel shall be at the expense of the indemnifying party and shall
be paid as they are incurred. After such notice from the indemnifying party to such
indemnified party, the indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the prior written consent
of the indemnifying party (which consent shall not be unreasonably withheld), unless such
indemnified party waived in writing its rights under this Section 8, in which case the
indemnified party may effect such a settlement without such consent.

-24-

 

	(d)	 	No indemnifying party shall be liable under this Section 8 for any settlement of any
claim or action (or threatened claim or action) effected without its written consent, which
shall not be unreasonably withheld, but if a claim or action is settled with its written
consent, or if there is a final judgment for the plaintiff with respect to any such claim or
action, each indemnifying party jointly and severally agrees, subject to the exceptions and
limitations set forth above, to indemnify and hold harmless each indemnified party from and
against any and all losses, claims, damages or liabilities (and legal and other expenses as
set forth above) incurred by reason of such settlement or judgment. No indemnifying party
shall, without the prior written consent of the indemnified party (which consent shall not be
unreasonably withheld), effect any settlement or compromise of any pending or threatened
proceeding in respect of which the indemnified party is or could have been a party, or
indemnity could have been sought hereunder by the indemnified party, unless such settlement
(A) includes an unconditional written release of the indemnified party, in form and substance
satisfactory to the indemnified party, from all liability on claims that are the subject
matter of such proceeding and (B) does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of the indemnified party.

	(e)	 	In circumstances in which the indemnity agreement provided for in the preceding
paragraphs of this Section 8 is unavailable to, or insufficient to hold harmless, an
indemnified party in respect of any losses, claims, damages or liabilities (or actions in
respect thereof), each indemnifying party, in order to provide for just and equitable
contributions, shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying
party or parties, on the one hand, and the indemnified party, on the other hand, from the
Offering or (ii) if the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of the
indemnifying party or parties, on the one hand, and the indemnified party, on the other hand,
in connection with the statements or omissions or alleged statements or omissions that
resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The
relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the
other hand, shall be deemed to be in the same proportion as the total proceeds from the
Offering (before deducting expenses) received by the Company bear to the total discounts and
commissions received by the Initial Purchasers. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company, on the one hand, or the Initial Purchasers, on the other
hand, the parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission or alleged statement or omissions, and any other
equitable considerations appropriate in the circumstances.

	(f)	 	The Company, the Guarantors and the Initial Purchasers agree that it would not be
equitable if the amount of such contribution determined pursuant to the immediately preceding
paragraph (e) were determined by pro rata or per capita allocation or by any other method of
allocation that does not take into account the equitable considerations referred to in the
first sentence of the immediately preceding paragraph (e). Notwithstanding any other
provision of this Section 8, the Initial Purchasers shall not be obligated to make
contributions hereunder that in the aggregate exceed the total discounts, commissions and
other compensation received by such Initial Purchasers under this Agreement, less the
aggregate amount of any damages that such Initial Purchasers have otherwise been required to
pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions
to state a material fact. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligation to
contribute hereunder shall be several in proportion to their respective purchase obligations
hereunder and not joint. For purposes of the immediately preceding

-25-

 

	 	 	paragraph (e), each person, if any, who controls the Initial Purchasers within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Initial Purchasers, and each director of the Company and the Guarantors,
each officer of the Company and the Guarantors and each person, if any, who controls either
of the Company or the Guarantors within the meaning of Section 15 of the Act or Section 20
of the Exchange Act, shall have the same rights to contribution as the Company and the
Guarantors.

          9. Termination. The Initial Purchasers may terminate this Agreement at any time prior
to the applicable Closing Date by written notice to the Company if any of the following has
occurred:

	(a)	 	since the date hereof, any Material Adverse Effect or development involving or
expected to result in a prospective Material Adverse Effect that could, in the
Representatives’ sole judgment, be expected to (i) make it impracticable or inadvisable to
proceed with the offering or delivery of the Securities on the terms and in the manner
contemplated in the Offering Memorandum, or (ii) materially impair the investment quality of
any of the Securities;

	(b)	 	the failure of the Company or the Guarantors to satisfy the conditions contained in
Section 7(a) hereof on or prior to the applicable Closing Date;

	(c)	 	any outbreak or escalation of hostilities or other national or international calamity
or crisis, including acts of terrorism, or material adverse change or disruption in economic
conditions in, or in the financial markets of, the United States (it being understood that any
such change or disruption shall be relative to such conditions and markets as in effect on the
date hereof), if the effect of such outbreak, escalation, calamity, crisis, act or material
adverse change in the economic conditions in, or in the financial markets of, the United
States could be reasonably expected to make it, in the Representatives’ sole judgment,
impracticable or inadvisable to market or proceed with the offering, sale or delivery of the
Securities on the terms and in the manner contemplated in the Offering Memorandum or to
enforce contracts for the sale of any of the Securities;

	(d)	 	trading in the Company’s common stock shall have been suspended by the SEC or Nasdaq
or the suspension or limitation of trading generally in securities on the New York Stock
Exchange or Nasdaq or any setting of limitations on prices for securities on any such
exchange;

	(e)	 	the enactment, publication, decree or other promulgation after the date hereof of any
Applicable Law that in the Initial Purchasers’ counsel’s sole opinion materially and adversely
affects, or could be reasonably expected to materially and adversely affect, the properties,
business, prospects, operations, earnings, assets, liabilities or condition (financial or
otherwise) of the Company and the Subsidiaries, taken as a whole;

	(f)	 	any securities of the Company shall have been downgraded or placed on any “watch
list” for possible downgrading by any “nationally recognized statistical rating organization,”
as such term is defined for purposes of Rule 436(g)(2) under the Act;

	(g)	 	the representation and warranty contained in the first sentence of Section 4(a) of
this Agreement is incorrect in any way; or

	(h)	 	the declaration of a banking moratorium by any Governmental Authority; or the taking
of any action by any Governmental Authority after the date hereof in respect of its monetary
or fiscal affairs that in the Representatives’ opinion could reasonably be expected to have a
material adverse effect on the financial markets in the United States or elsewhere.

-26-

 

          10. Survival of Representations and Indemnities. The representations and warranties,
covenants, indemnities and contribution and expense reimbursement provisions and other agreements,
representations and warranties of the Company and the Guarantors set forth in or made pursuant to
this Agreement shall remain operative and in full force and effect, and will survive, regardless of
(i) any investigation, or statement as to the results thereof, made by or on behalf of the Initial
Purchasers, (ii) acceptance of the Securities, and payment for them hereunder, and (iii) any
termination of this Agreement.

          11. Defaulting Initial Purchaser. If, on the applicable Closing Date, any one of the
Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to
purchase hereunder on such date, and the aggregate principal amount of Securities which such
defaulting Initial Purchaser agreed but failed or refused to purchase is not more than one tenth of
the aggregate principal amount of Securities to be purchased on such date, the other Initial
Purchasers shall be obligated severally in the proportions that the principal amount of Securities
set forth opposite their respective names in Schedule I hereto bears to the aggregate
principal amount of Securities set forth opposite the names of all such non defaulting Initial
Purchasers to purchase the Securities which such defaulting Initial Purchaser agreed but failed or
refused to purchase on such date. If, on the applicable Closing Date any Initial Purchaser shall
fail or refuse to purchase Securities which it or they have agreed to purchase hereunder on such
date and the aggregate principal amount of Securities with respect to which such default occurs is
more than one tenth of the aggregate principal amount of Securities to be purchased on such date,
and arrangements satisfactory to the non-defaulting Initial Purchasers and the Company for the
purchase of such Securities are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of the non-defaulting Initial Purchasers or of the Company.
Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from
liability in respect of any default of such Initial Purchaser under this Agreement.

          12. No Fiduciary Duty. The Company hereby acknowledges that the Initial Purchasers
are acting solely in connection with the purchase and sale of the Securities. The Company further
acknowledges that the Initial Purchasers are acting pursuant to a contractual relationship created
solely by this Agreement entered into on an arm’s length basis, and in no event do the parties
intend that the Initial Purchasers act or be responsible as a fiduciary to the Company, its
management, stockholders, creditors or any other person in connection with any activity that the
Initial Purchasers may undertake or have undertaken in furtherance of the purchase and sale of the
Securities, either before or after the date hereof. The Initial Purchasers hereby expressly
disclaim any fiduciary or similar obligations to the Company, either in connection with the
transactions contemplated by this Agreement or any matters leading up to such transactions, and the
Company hereby confirms its understanding and agreement to that effect. The Company and the Initial
Purchasers agree that they are each responsible for making their own independent judgments with
respect to any such transactions and that any opinions or views expressed by the Initial Purchasers
to the Company regarding such transactions, including, but not limited to, any opinions or views
with respect to the price or market for the Securities, do not constitute advice or recommendations
to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any
claims that the Company may have against the Initial Purchasers with respect to any breach or
alleged breach of any fiduciary or similar duty to the Company in connection with the transactions
contemplated by this Agreement or any matters leading up to such transactions.

and no other person shall acquire or have any right under or by virtue of this Agreement. The
term “successors and assigns” shall not include a purchaser of any of the Securities from the
Initial Purchasers merely because of such purchase.

and negotiations with respect to the subject matter hereof. This Agreement may be signed in

million, or approximately $58.2 million, for the Bauer Acquisition (as defined
in the Preliminary Offering Memorandum), to pay approximately $3.0 million in
fees and expenses related to this offering and for other general corporate
purposes, including potential acquisitions. This offering is not contingent on
the completion of the Bauer Acquisition.

 

 

	 	 	 

	Optional Redemption:

	 	The Issuer may not redeem the Notes prior to March 1, 2015. 
	 
	 

	 	On or after March 1, 2015, the Issuer may redeem for cash all or part of the

for 20 or more trading days in a period of 30 consecutive trading days ending
on the trading day prior to the date the Issuer provides the notice of
redemption exceeds 130% of the conversion price in effect on each such trading
day. The redemption price will equal the sum of 100% of the principal amount
of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but
not including, the redemption date, plus a “make-whole premium” payment in
cash, shares of the Issuer’s common stock or a combination of cash and shares

	 	On or after March 1, 2018, the Issuer may redeem for cash all or a portion of

repurchase date”) at a price equal to 100% of the principal amount of the
Notes to be repurchased plus any accrued and unpaid interest (including
contingent interest and additional interest, if any) to, but not including,
the option repurchase date.
	 
	 	 
	Fundamental 

Changes:

	 	If the Issuer undergoes a fundamental change, holders may require the Issuer

repurchased plus accrued and unpaid interest (including contingent interest
and additional interest, if any) to, but not including, the fundamental change
repurchase date.

	 	The Notes will be senior unsecured obligations of the Issuer. The Notes and
the subsidiary guarantees will rank: (1) equally in right of payment with all
of the Issuer’s and the Guarantors’ existing and future senior unsecured
indebtedness; (2) effectively junior in right of payment to all of the
Issuer’s and the Guarantors’ existing and future secured indebtedness,
including any borrowings under the Issuer’s credit facilities and the Issuer’s
senior secured notes, to the extent of the asset securing such indebtedness;
(3) effectively junior to all of the liabilities of the Issuer’s subsidiaries
that have not guaranteed the Notes; and (4) senior in right of payment to any
future subordinated indebtedness of the Issuer and the Issuer’s guarantors.

	Adjustment to Conversion
Rate upon a Make-Whole
Fundamental Change:

	 	The number of additional shares by which the applicable conversion rate for
the Notes will be increased for conversions in connection with a make-whole
fundamental change will be determined by reference to the table below, based
on the date on which such make-whole fundamental change occurs or becomes
effective (the “effective date”) and the price paid (or deemed to be paid) per
share of common stock in such make-whole fundamental change (the “stock
price”).
	 
	 	 
	 

	 	The stock prices set forth in the first row of the table below (i.e., column
headers) will be adjusted as of any date on which the conversion rate of the
Notes is otherwise adjusted. The adjusted stock prices will equal the stock
prices applicable immediately prior to such adjustment, multiplied by a
fraction, the numerator of which is the conversion rate in effect immediately
prior to the adjustment giving rise to the stock price adjustment, and the
denominator of which is the conversion rate as so adjusted. The number of
additional shares will be adjusted in the same manner as the conversion rate
as set forth under “Description of Notes—Conversion rate adjustments.”
	 
	 	 
	 

	 	The following table sets forth the hypothetical stock price and the number of
additional shares to be received per $1,000 principal amount of the Notes:

The exact stock prices and effective dates may not be set forth in the table above, in
which case:

	•	 	if the stock price is between two stock price amounts in the table or the effective
date is between two effective dates in the table, the number of additional shares will be
determined by a straight-line interpolation between the number of additional shares set
forth for the higher and lower stock price amounts and the earlier and later dates, as
applicable, based on a 365-day year;
	 
	•	 	if the stock price is greater than $90.00 per share (subject to adjustment), no
additional shares will be added to the conversion rate; and
	 
	•	 	if the stock price is less than $20.52 per share (subject to adjustment), no
additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the total number of shares of common stock
issuable upon conversion of the Notes exceed 48.7329 per $1,000 principal amount of Notes,
subject to adjustments in the same manner as the conversion rate as set forth under the
heading “Description of Notes—Conversion rate adjustments.”

You should rely on the information contained or incorporated by reference in the Preliminary
Offering Memorandum, as supplemented by this pricing term sheet, in making an investment decision

     2. The Company and each Covered Guarantor has full corporate power and authority to conduct
its business as described in the Pricing Disclosure Package and the Final Offering Memorandum and

     3. The Purchase Agreement has been duly and validly authorized, executed and delivered by the

the Trustee, is a legally valid and binding agreement of the Company and the Covered Guarantors,

Notwithstanding the foregoing, we express no opinion as to the validity, legally binding effect or
enforceability of any provision of the Indenture that requires or relates to the payment of any

Memorandum or pursuant to the exercise of convertible securities or options referred to in the
Pricing Disclosure Package and the Final Offering Memorandum). To our knowledge, each of the
outstanding shares of capital stock and membership interests, as the case may be, of the Company
and the Covered Guarantors have been duly authorized and validly issued, are fully paid and
non-assessable, and to our knowledge, were not issued in violation of any preemptive or similar
rights, and to our knowledge, the outstanding shares of capital stock and membership interests, as
the case may be, of the Covered Guarantors are owned, directly or indirectly, by the Company or
the Covered Guarantors, as the case may be, free and clear of all security interests, liens,
encumbrances, equities and claims or restrictions on transferability (other than those imposed by
the Act and the securities or “Blue Sky” laws of certain domestic or foreign jurisdictions) or
voting (other than Permitted Liens).

     9. The Securities are in the form contemplated by the Indenture. The Securities, when
executed and delivered by the Company and the Covered Guarantors in accordance with the terms of
the Indenture (assuming the due authorization, execution and delivery of the Indenture by the
Trustee and due authentication and delivery of such guarantees by the Trustee in accordance with
the Indenture), will be entitled to the benefits of the Indenture.

     10. When executed and delivered, the Transaction Documents will conform in all material
respects to the descriptions thereof in the Pricing Disclosure Package and the Final Offering
Memorandum.

     11. To our knowledge, no Proceeding is pending or threatened against or affecting the Company
or any of the Covered Guarantors that (i) seeks to or does restrain, enjoin, prevent the
consummation of or otherwise questions the validity or legality of the Transaction Documents or
any of the transactions contemplated therein, or (ii) could, singly or in the aggregate,
reasonably be expected to have a Material Adverse Effect. To our knowledge, neither the Company,
nor any Covered Guarantor, is subject to any judgment, order, decree, rule or regulation of any
Governmental Authority that could, singly or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

     12. The execution and delivery by the Company and each Covered Guarantor of each Transaction
Document to which it is a party does not, and the performance by each of the Company and the
Covered Guarantors of its obligations thereunder, including the issuance and sale of the
Securities to the Initial Purchasers, and the transactions contemplated thereby (including the
issuance of the Conversion Shares upon conversion thereof), will not (i) conflict with, or result
in a violation or breach of, any of the provisions of the Charter Documents of the Company or any
Covered Guarantor; (ii) conflict with or violate any United States federal or state law, rule or regulation to be
applicable to the Company or any Covered Guarantor, or any order, judgment or decree known to us
to be applicable to the

A-2

 

Company, any Covered Guarantor or the Transaction Documents or by which
any property or asset of the Company or any Covered Guarantor is or may be bound; or (iii)
conflict with, or result in a violation or breach of, any of the material terms or provisions of,
or constitute a default (with or without due notice and/or lapse of time) under (A) any loan or
credit agreement, indenture (including, without limitation, the Indenture), mortgage, note or
other material agreement or instrument known to us to which the Company or any Covered Guarantor
is a party or by which they or any of their properties or assets is or may be bound or (B) any
material agreement or instrument listed as an exhibit to the Annual Report on the Form 10-K for
the year ended December 31, 2010 of the Company, except in the case of (ii) or (iii) above, where
such breach, conflict, violation or default would not result in a Material Adverse Effect.

     13. No Governmental Authorization (as defined below) or consent, approval authorization or
order of any third party, is required for the issuance and sale by the Company of the Securities
to the Initial Purchasers, the execution, delivery or performance by the Company or the Covered
Guarantors of any Transaction Document to which it is a party or for the consummation of the
transactions contemplated by the Transaction Documents (including the issuance of the Conversion
Shares upon conversion thereof), except such as have been obtained and such as may be required
under state securities or “Blue Sky” laws in connection with the purchase and resale of the
Securities by the Initial Purchasers.

     “Governmental Authorization” means any judgment, order or decree, consent, authorization,
approval, order, exemption, registration, qualification or other action of, or filing with or
notice to any Governmental Authority.

     14. The statements in the Pricing Disclosure Package and the Final Offering Memorandum under
the captions “Description of Notes” and “Description of Certain Indebtedness,” to the extent that
such information constitutes a summary of the legal matters, documents or proceedings referred to
therein, fairly present in all material respects such legal matters, documents and proceedings.
The statements under the caption “Material United States Federal Tax Considerations,” in the
Pricing Disclosure Package and the Final Offering Memorandum, insofar as such statements summarize
certain federal income and estate tax laws of the United States, constitute a fair summary of the
principal U.S. federal income and estate tax consequences of an investment in the Securities

     15. No registration under the Act of the Securities is required in connection with the
issuance and sale of the Securities to the Initial Purchasers as contemplated by the Purchase
Agreement and the Pricing Disclosure Package and the Final Offering Memorandum or in connection
with the initial resale of the Securities by any Initial Purchaser in accordance with the Purchase
Agreement, and the Indenture is not required to be qualified under the TIA, assuming (i) (A) that
the purchasers who buy the Securities in the initial resale thereof are “qualified institutional
buyers” as defined in Rule 144A promulgated under the Act, (B) institutional “accredited
investors” as defined in Rule 501(a)(1), (2), (3) or (7) under the Act or (C) that the offer or
sale of the Securities is made in an offshore transaction as defined in Regulation S; and (ii) the
accuracy of each Initial Purchaser’s representations in Section 6 of the Purchase Agreement and
those of the Company contained in the Purchase Agreement regarding the absence of a general
solicitation in connection with the sale of the Securities to the Initial Purchasers and the
initial resale thereof.

     16. The issuance and sale by the Company of the Securities as contemplated by the Purchase
Agreement does not violate Regulation T, U or X of the Board of Governors of the Federal Reserve
System.

     17. The documents incorporated by reference in the Final Offering Memorandum (other than the
financial statements and supporting schedules and the other financial data included therein or
omitted

A-3

 

therefrom, as to which we express no opinion), when they were filed with the SEC, complied
as to form in all material respects with the requirements of the Exchange Act.

     18. Neither the Company nor any Covered Guarantor is and, after giving effect to the offering
and sale of the Securities and the application of the proceeds
therefrom as described in the Pricing Disclosure Package and the Final Offering Memorandum, will be an “investment company” (as
defined in the Investment Company Act) or a subsidiary thereof.

     19. The Indenture complies with the TIA.

Company notifies the Representatives in writing that it does not intend to proceed with the
Offering or (ii) if the Purchase Agreement (other than the provisions thereof which survive
termination) shall terminate or be terminated for any reason prior to payment for and delivery of

EXHIBIT C

FORM OF OPINION OF

PENNSYLVANNIA COUNSEL

     1. TB Wood’s Incorporated (“TB Wood’s”) is a corporation duly organized, validly existing and
subsisting under the laws of the Commonwealth of Pennsylvania.

     2. TB Wood’s has corporate power and authority to conduct its businesses as described in the
Pricing Disclosure Package and the Final Offering Memorandum and to take, and has duly taken, all
action necessary under its respective governing instruments to authorize the execution, delivery
and performance of each Document to which it is a party and to consummate the transactions
contemplated thereby, and has duly executed and delivered each Document to which it is a party.

     3. Each Document to which TB Wood’s is a party constitutes a legal, valid and binding
obligation of TB Wood’s, enforceable against TB Wood’s in accordance with its terms.

     4. Each of the outstanding shares of capital stock of TB Wood’s has been duly authorized and
validly issued, is fully paid and non-assessable and, to our knowledge, was not issued in violation
of any preemptive or similar rights and is owned, to our knowledge, directly or indirectly, by the
Company or the Guarantors, as the case may be, free and clear of all security interests (that can
be perfected by filing under Division 9 of the Uniform Commercial Code as in effect in the
Commonwealth of Pennsylvania), liens, encumbrances, equities and claims or restrictions on
transferability (other than those imposed by the Act and the securities or “Blue Sky” laws of
certain domestic or foreign jurisdictions) or voting (other than Permitted Liens).

     5. No Governmental Authorization (as defined below) or consent, approval authorization or
order of any third party, is required for the execution, delivery or performance by TB Wood’s of
any Document to which it is a party or for the consummation of the transactions contemplated by the
Documents, except such as have been obtained and such as may be required under state securities or
“Blue Sky” laws in connection with the purchase and resale of the Notes by the Initial Purchaser,

     6. The choice of New York law to govern the construction and interpretation of the Documents
is a valid and effective choice of law under the laws of the Commonwealth of Pennsylvania and
adherence to existing judicial precedents under Pennsylvania law would require courts sitting in
the Commonwealth of Pennsylvania to abide by such choice of law, provided that such courts would
find that the laws of the State of New York, as so applied, are not contrary to the public policy
of the Commonwealth of Pennsylvania.

     7. The execution and delivery by TB Wood’s of each Document to which it is a party does not,
and the performance by TB Wood’s of its obligations thereunder, and the transactions contemplated
thereby, will not (i) result in a violation or breach of, (A) any of the provisions of the Charter
Documents of TB Wood’s, (B) any provisions of any Commonwealth of Pennsylvania statute, rule or
regulation known to us to be applicable to TB Wood’s, or (C) violate any judgment or order of any
Pennsylvania governmental authority known to us and binding upon TB Wood’s.
