authenticate and deliver said Notes to or upon the written order of the Company, signed by (a) its
Chairman of the Board of Directors, Vice Chairman of the Board of Directors, Chief Executive
Officer, President, Chief Financial Officer or any Vice President and (b) its Treasurer or any
Assistant Treasurer, or its Secretary or any Assistant Secretary, without any further action by the

shall, upon receipt of an Officers’ Certificate specifying the amount of Notes to be authenticated
and the date on which such Notes are to be authenticated and certifying that all conditions
precedent to the issuance of the Additional Notes contained herein have been complied with and that
no default or Event of Default would occur as a result of the issuance of such Additional Notes,
authenticate and deliver said Additional Notes to or upon the written order of the Company, signed
as set forth in the preceding sentence; provided that Additional Notes may be issued under this
Indenture only if such Additional Notes and the Notes constitute the same issue for United States
federal income tax purposes. The Notes and the Additional Notes, if any, shall constitute one
series for all purposes under this Indenture, including, without limitation, amendments, waivers
and redemptions.

          Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be
borne by such Notes shall be substantially in the form set forth in Exhibit A. The terms and
provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are
hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

          Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends, endorsements or changes as the officers executing the same may approve
(execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the
provisions of this Indenture, or as may be required by the Custodian, the Depositary or by the
National Association of Securities Dealers, Inc. in order for the Notes to be tradeable on the
Portal Market or as may be required for the Notes to be tradeable on any other market developed for
trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law
or with any rule or regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be listed, or to conform
to usage, or to indicate any special limitations or restrictions to which any particular Notes are
subject.

11

 

          So long as the Notes are eligible for book-entry settlement with the Depositary, or unless
otherwise required by law, or otherwise contemplated by Section 2.05(b), all of the Notes will be
represented by one or more Notes in global form registered in the name of the Depositary or the
nominee of the Depositary (a “Global Note”). The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with this Indenture and
the applicable procedures of the Depositary. Except as provided in Section 2.05(b), beneficial
owners of a Global Note will not receive or be entitled to receive physical delivery of
certificates in definitive form and will not be considered holders of such Global Note.

          Notwithstanding any other provision of this Indenture, so long as a series of Notes is a
Global Note, the parties hereto will be bound at all times by the applicable procedures of the
Depositary with respect to such series.

          Any Global Note shall represent such of the outstanding Notes as shall be specified therein
and shall provide that it shall represent the aggregate amount of outstanding Notes from time to
time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may
from time to time be increased or reduced to reflect redemptions, repurchases, conversions,
transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of
any increase or decrease in the amount of outstanding Notes represented thereby shall be made by
the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions
given by the holder of such Notes in accordance with this Indenture. Payment of principal of and
interest and premium, if any, on any Global Note shall be made to the holder of such Global Note.

at the close of business on any record date with respect to any interest payment date shall be
entitled to receive the interest payable on such interest payment date, except that the interest
payable upon redemption or repurchase will be payable to the Person to whom principal is payable
pursuant to such redemption or repurchase (unless the redemption date or the Repurchase Date, as
the case may be, is an interest payment date, in which case the semi-annual payment of interest
becoming due on such date shall be payable to the holders of such Notes registered as such on the
applicable record date). Interest shall be payable at the office of the Company maintained by the
Company for such purposes in the Borough of Manhattan, The City of New York, which shall initially
be the Corporate Trust Office of the Trustee and may, as the Company shall specify to the paying
agent in writing by each record date, be paid either (i) by check mailed to the address of the
Person entitled thereto as it appears in the Note register (provided that any holder of Notes with
an aggregate principal amount in excess of $2,000,000 shall, at the written election of such holder
(such election to be made prior to the relevant record date and to contain appropriate wire
transfer information), be paid by wire transfer in immediately available funds) or (ii) by transfer
to an account maintained by such Person located

12

 

in the United States; provided that payments to the Depositary will be made by wire transfer
of immediately available funds to the account of the Depositary or its nominee. The term “record
date” with respect to any interest payment date shall mean the February 1 or August 1 preceding the
applicable February 15 or August 15 interest payment date, respectively.

          Any interest on any Note which is payable, but is not punctually paid or duly provided for, on
any February 15 or August 15 (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Noteholder on the relevant record date by virtue of his having been such Noteholder,
and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Notes (or their respective Predecessor Notes) are registered at the close of
business on a special record date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall provide an Officers’ Certificate to the
Trustee specifying the amount of Defaulted Interest proposed to be paid on each Note and the
date of the proposed payment (which shall be not less than twenty-five (25) days after the
receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date),
and at the same time the Company shall deposit with the Trustee an amount of money equal to
the aggregate amount to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit on or prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the
Trustee shall fix a special record date for the payment of such Defaulted Interest which
shall be not more than fifteen (15) days and not less than ten (10) days prior to the date
of the proposed payment, and not less than ten (10) days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the Company of such
special record date and, in the name and at the expense of the Company, shall cause notice
of the proposed payment of such Defaulted Interest and the special record date therefor to
be mailed, first-class postage prepaid, to each holder at his address as it appears in the
Note register, not less than ten (10) days prior to such special record date. Notice of the
proposed payment of such Defaulted Interest and the special record date therefor having been
so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or
their respective Predecessor Notes) are registered at the close of business on such special
record date and shall no longer be payable pursuant to the following clause (2) of this
Section 2.03.

     (2) The Company may make payment of any Defaulted Interest in any other lawful manner
not inconsistent with the requirements of any securities exchange or automated quotation
system on which the Notes may be listed or designated for issuance, and upon such notice as
may be required by such exchange or automated quotation system, if, after notice given by
the Company to the Trustee of the proposed payment pursuant to this clause, such manner of
payment shall be deemed practicable by the Trustee.

          Section 2.04. Execution and Authentication of Notes. The Notes shall be signed in the name
and on behalf of the Company by the manual or facsimile signature of its Chairman

13

 

of the Board of Directors, Vice Chairman of the Board of Directors, Chief Executive Officer,
President, Chief Financial Officer or any Vice President and attested by its Treasurer or any
Assistant Treasurer, or its Secretary or any Assistant Secretary. The signature of any of these
officers on the Notes may be manual or facsimile. Only such Notes as shall bear thereon a
certificate of authentication substantially in the form set forth on the form of Note attached as
Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the
Trustee as provided by Section 15.11), shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating
agent) upon any Note executed by the Company shall be conclusive evidence that the Note so
authenticated has been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture.

          In case any officer of the Company who shall have signed any of the Notes shall cease to be
such officer before the Notes so signed shall have been authenticated and delivered by the Trustee,
or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Notes had not ceased to be such officer of the
Company, and any Note may be signed on behalf of the Company by such persons as, at the actual date
of the execution of such Note, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such person was not such an officer.

          Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer. (a)
The Company shall cause to be kept at the Corporate Trust Office a register (the register
maintained in such office and in any other office or agency of the Company designated pursuant to
Section 4.02 being herein sometimes collectively referred to as the “Note register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. The Note register shall be in written form or in
any form capable of being converted into written form within a reasonably prompt period of time.
The Trustee is hereby appointed “Note registrar” for the purpose of registering Notes and transfers
of Notes as herein provided. The Company may appoint one or more co-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
which the Noteholder making the exchange is entitled to receive bearing registration numbers not
contemporaneously outstanding.

14

 

          All Notes issued upon any registration of transfer or exchange of Notes 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.

          All Notes presented or surrendered for registration of transfer or for exchange, redemption,
repurchase or conversion shall (if so required by the Company or the Note registrar) be duly
endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory
to the Company or the Note registrar, as the case may be, and the Notes shall be duly executed by
the Noteholder thereof or his attorney duly authorized in writing.

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

          Neither the Company nor the Trustee nor any Note registrar shall be required to exchange or
register a transfer of (a) any Notes for a period of fifteen (15) days next preceding any selection
of Notes to be redeemed, (b) any Notes or portions thereof called for redemption pursuant to
Section 3.02, (c) any Notes or portions thereof surrendered for conversion pursuant to Article 14,
(d) any Notes or portions thereof tendered for redemption (and not withdrawn) pursuant to Section
3.05 or (e) any Notes or portions thereof tendered for repurchase (and not withdrawn) pursuant to
Section 3.06.

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

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

     (ii) Notwithstanding any other provision in this Indenture, no Global Note may be
exchanged in whole or in part for Notes registered, and no transfer of a Global Note in
whole or in part may be registered, in the name of any Person other than the Depositary or a
nominee thereof unless (A) the Depositary (i) has notified the Company that it is unwilling
or unable to continue as Depositary for such Global Note or (ii) has ceased to be a clearing
agency registered under the Exchange Act and a successor Depositary is not appointed by the
Company within 90 days, (B) an Event of Default has occurred and is continuing and the
Maturity of the Notes shall have been accelerated in accordance with the terms of the Notes
and any holder shall have requested in writing the issuance of definitive certificated
securities, or (C) the Company, in its sole discretion, notifies the Trustee in writing that
it no longer wishes to have all the Notes represented by Global Notes. Any Global Note
exchanged pursuant to clause (A) or (B) above shall be so exchanged in whole and not in part
and any Global Note exchanged pursuant to clause (C) above may be exchanged in whole or from
time to time in part as directed by the Company. Any Note issued in exchange for a Global
Note or any portion thereof shall be a Global Note; provided that any such Note so issued
that is registered in the

15

 

name of a Person other than the Depositary or a nominee thereof shall not be a Global
Note.

     (iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to
clause (ii) above and which is not a Global Note shall be issued in definitive, fully
registered form, without interest coupons, shall have an aggregate principal amount equal to
that of such Global Note or portion thereof to be so exchanged, shall be registered in such
names and be in such authorized denominations as the Depositary shall designate and shall
bear any legends required hereunder. Any Global Note to be exchanged in whole shall be
surrendered by the Depositary to the Trustee, as Note registrar. With regard to any Global
Note to be exchanged in part, either such Global Note shall be so surrendered for exchange
or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to
such Global Note, the principal amount thereof shall be reduced, by an amount equal to the
portion thereof to be so exchanged, by means of an appropriate adjustment made on the
records of the Trustee. Upon any such surrender or adjustment, the Trustee shall
authenticate and make available for delivery the Note issuable on such exchange to or upon
the written order of the Depositary or an authorized representative thereof.

     (iv) In the event of the occurrence of any of the events specified in clause (ii)
above, the Company will promptly make available to the Trustee a reasonable supply of
certificated Notes in definitive, fully registered form, without interest coupons.

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

     (vi) At such time as all interests in a Global Note have been redeemed, repurchased,
converted, canceled or exchanged for Notes in certificated form, such Global Note shall,
upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and
instructions existing between the Depositary and the Custodian. At any time prior to such
cancellation, if any interest in a Global Note is redeemed, repurchased, converted, canceled
or exchanged for Notes in certificated form, 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, 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.

          (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 those set forth in the legend below) unless such restrictions on transfer shall be
waived by written consent of the Company, and the holder of each such Restricted Security, by such
Noteholder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used
in Sections 2.05(c) and 2.05(d), the term “transfer” encompasses any sale, pledge, loan, transfer,
assignment, conveyance or other disposition whatsoever of any Restricted Security or any interest
therein.

          Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under
the Securities Act (or any successor provision), 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 Note has been sold
pursuant to a registration statement that has been declared effective under the Securities Act (and
which continues to be effective at the time of such transfer), or unless otherwise agreed by the
Company in writing, with written notice thereof to the Trustee:

THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND,
ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING
SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT);
(2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO
SALES OF THE NOTE EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR
ANY SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THIS NOTE OR THE COMMON STOCK
ISSUABLE UPON CONVERSION OF THIS NOTE EXCEPT (A) TO NII HOLDINGS, INC. OR ANY
SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE
144A UNDER THE SECURITIES ACT; (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION
PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
(AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3) PRIOR TO
SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(D) ABOVE), IT WILL
FURNISH TO WILMINGTON TRUST COMPANY, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS
APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE
MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A

17

 

TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND
(4) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON
THE EARLIER OF THE TRANSFER OF THIS NOTE PURSUANT TO CLAUSE (2)(D) ABOVE OR UPON ANY
TRANSFER OF THIS NOTE UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
PROVISION). THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTION.

          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 or as to conditions for
removal of the foregoing legend set forth therein have been satisfied 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). If the Restricted Security
surrendered for exchange is represented by a Global Note bearing the legend set forth in this
Section 2.05(c), the principal amount of the legended Global Note shall be reduced by the
appropriate principal amount and the principal amount of a Global Note without the legend set forth
in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note without
the legend set forth in this Section 2.05(c) is not then outstanding, the Company shall execute and
the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

          (d) Until the expiration of the holding period applicable to sales thereof under Rule 144(k)
under the Securities Act (or any successor provision), any stock certificate representing Common
Stock issued upon conversion of any Note shall bear a legend in substantially the following form,
unless such Common Stock has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the time of such
transfer) or such Common Stock has been issued upon conversion of Notes that have been transferred
pursuant to a registration statement that has been declared effective under the Securities Act, or
unless otherwise agreed by the Company in writing with written notice thereof to the transfer
agent:

THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES
LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT, UNTIL THE EXPIRATION OF THE
HOLDING PERIOD APPLICABLE TO SALES OF THE COMMON STOCK EVIDENCED HEREBY, UNDER RULE
144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), (1) IT WILL NOT RESELL
OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO NII HOLDINGS,
INC. OR TO ANY SUBSIDIARY THEREOF, (B) TO A

18

 

“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT)
IN COMPLIANCE WITH RULE 144A, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION
PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
(AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2) PRIOR TO
SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (1)(D) ABOVE), IT WILL
FURNISH TO EQUISERVE TRUST COMPANY, N.A., AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER
AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS
SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING
MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH
PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A
TRANSFER PURSUANT TO CLAUSE (1)(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF
THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE
COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE (1)(D) ABOVE OR UPON ANY TRANSFER
OF THE COMMON STOCK EVIDENCED HEREBY AFTER THE EXPIRATION OF THE HOLDING PERIOD
APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE
SECURITIES ACT (OR ANY SUCCESSOR PROVISION).

          Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms or as to which the conditions for removal of the foregoing legend set
forth therein have been satisfied 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 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 of a Note that, prior to the
expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities
Act (or any successor provision), is purchased 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
which 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).

          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 make available for delivery, a new Note, bearing a number not

19

 

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 for 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.

          Following receipt by the Trustee or such authenticating agent, as the case may be, of
satisfactory security or indemnity and evidence, as described in the preceding paragraph, the
Trustee or such authenticating agent may authenticate any such substituted Note and make available
for delivery such Note. Upon the issuance of any substituted Note, either the Company, the Trustee
or both 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 which has matured or is about to mature or has been called for
redemption or has been tendered for redemption upon a Fundamental Change (and not withdrawn) or has
been surrendered for repurchase on a Repurchase Date (and not withdrawn) or is to be converted into
Common Stock or cash shall become mutilated or be destroyed, lost or stolen, the Company may,
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 in connection with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, the Trustee and, if applicable, any paying agent or
Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Note and
of the ownership thereof.

          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 redemption 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 or
redemption or repurchase of negotiable instruments or other securities without their surrender.

          Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon
the written request of the Company, authenticate and deliver temporary Notes (printed or
lithographed). Temporary Notes shall be issuable in any authorized

20

 

denomination, and substantially in the form of the Notes in certificated form, 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 Notes in certificated form. Without
unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating
agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in
exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and
the Trustee or such authenticating agent shall authenticate and make available for delivery in
exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated
form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same
benefits and subject to the same limitations under this Indenture as Notes in certificated form
authenticated and delivered hereunder.

          Section 2.08. Cancellation of Notes. 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.
All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, if surrendered to the Company or any paying agent or any Note
registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or,
if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in
lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee
shall dispose of such canceled Notes in accordance with its customary procedures. Any Notes
surrendered by the Company to the Trustee for cancellation shall be accompanied by an Officers’
Certificate requesting the Trustee to effect such 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 notices of redemption
as a convenience to Noteholders; 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 as contained in any
notice of a redemption and that reliance may be placed only on the other identification numbers
printed on the Notes, and any such redemption shall not be affected by any defect in or omission of
such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE III

Redemption and Repurchase of Notes

          Section 3.01. Redemption of Notes at the Option of the Company. Except as otherwise provided
in Section 3.05, the Company may not redeem any Notes prior to August 20, 2010. At any time on or
after August 20, 2010, the Notes may be redeemed at the option of the Company (an “Optional
Redemption”), in whole or in part, upon notice as set forth in Section 3.02, at any time for a
redemption price in cash equal to 100% of the principal amount of the notes to be redeemed,
together with any accrued and unpaid interest (including additional

21

 

amounts, if any) up to but excluding the date fixed for redemption. The notes are not subject
to redemption through the operation of any sinking fund.

          Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Company shall
desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant
to Section 3.01, it shall fix a date for redemption and it or, at its written request received by
the Trustee not fewer than forty-five (45) days prior (or such shorter period of time as may be
acceptable to the Trustee) to the date fixed for redemption, the Trustee in the name of and at the
expense of the Company, shall mail or cause to be mailed a notice of such redemption not fewer than
thirty (30) nor more than sixty (60) days prior to the redemption date (any such date an “Optional
Redemption Notice 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 that if the Company shall give such
notice, it shall give substantially concurrent written notice of the redemption date to the
Trustee. Such mailing shall be by first class mail. The notice, if mailed in the manner herein
provided, shall be conclusively presumed to have been duly given, whether or not the holder
receives such notice. In any case, failure to give such notice by mail or any defect in the notice
to the holder of any 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. Concurrently with the mailing of
any such notice of redemption, the Company shall issue a press release announcing such redemption,
the form and content of which press release shall be determined by the Company in its sole
discretion. The failure to issue any such press release or any defect therein shall not affect the
validity of the redemption notice or any of the proceedings for the redemption of any Note called
for redemption.

          Each such notice of redemption shall specify the aggregate principal amount of Notes to be
redeemed, the CUSIP number or numbers of the Notes being redeemed, the date fixed for redemption
(which shall be a Business Day), the redemption price at which Notes are to be redeemed, the place
or places of payment, that payment will be made upon presentation and surrender of such Notes, that
interest accrued to the date fixed for redemption will be paid as specified in said notice, and
that on and after said date interest thereon or on the portion thereof to be redeemed will cease to
accrue. Such notice shall also state (x) the current Conversion Rate and the date on which the
right to convert such Notes or portions thereof will expire and (y) the Company’s election to
deliver shares of Common Stock or to pay cash in lieu of delivery of shares of Common Stock with
respect to any Notes or portions thereof converted prior to the redemption date. If fewer than all
the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed
(including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of
redemption shall state the portion of the principal amount thereof to be redeemed and shall state
that, on and after the redemption date, upon surrender of such Note, a new Note or Notes in
principal amount equal to the unredeemed portion thereof will be issued.

          On or prior to the redemption date specified in the notice of redemption given as provided in
this Section 3.02, the Company will deposit with the Trustee or with one or more paying agents (or,
if the Company is acting as the paying agent, set aside, segregate and hold in trust as provided in
Section 4.04) an amount of money in immediately available funds sufficient to redeem on the
redemption date all the Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for conversion) at the appropriate redemption price,

22

 

together with accrued interest to, but excluding, the redemption date; provided that if such
payment is made on the redemption date it must be received by the Trustee or paying agent, as the
case may be, by 10:00 a.m. New York City time on such date. The Company shall be entitled to
retain any interest, yield or gain on amounts deposited with the Trustee or any paying agent
pursuant to this Section 3.02 in excess of amounts required hereunder to pay the redemption price
and accrued interest to, but excluding, the redemption date. If any Note called for redemption is
converted pursuant hereto prior to such redemption date, any money deposited with the Trustee or
any paying agent or so segregated and held in trust for the redemption of such Note shall be paid
to the Company upon its written request, or, if then held by the Company, shall be discharged from
such trust. Whenever any Notes are to be redeemed pursuant to Section 3.01, the Company will give
the Trustee written notice in the form of an Officers’ Certificate not fewer than forty-five (45)
days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption
date as to the aggregate principal amount of Notes to be redeemed.

          If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the
Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in
principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method
the Trustee deems fair and appropriate. If any Note selected for partial redemption is submitted
for conversion in part after such selection, the portion of such Note submitted for conversion
shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The
Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all
purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the
mailing of the notice of redemption.

          Upon any redemption of less than all of the outstanding Notes, the Company and the Trustee may
(but need not), solely for purposes of determining the pro rata allocation among such Notes as are
unconverted and outstanding at the time of redemption, treat as outstanding any Notes surrendered
for conversion during the period of fifteen (15) days next preceding the mailing of a notice of
redemption and may (but need not) treat as outstanding any Note authenticated and delivered during
such period in exchange for the unconverted portion of any Note converted in part during such
period.

          Section 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption
has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which
such notice has been given shall, unless converted pursuant to the terms hereof, become due and
payable on the date fixed for redemption and at the place or places stated in such notice at the
applicable redemption price, together with interest accrued to (but excluding) the redemption date,
and on and after said date (unless the Company shall default in the payment of such Notes at the
redemption price, together with interest accrued to said date) interest on the Notes or portion of
Notes so called for redemption shall cease to accrue and, after the close of business on the
Business Day immediately preceding the redemption date, such Notes shall cease to be convertible
and, except as provided in Sections 7.06 and 12.04, to be entitled to any benefit or security under
this Indenture, and the holders thereof shall have no right in respect of such Notes except the
right to receive the redemption price thereof and unpaid interest to (but excluding) the redemption
date. On presentation and surrender of such Notes at a place of payment in said notice specified,
the said Notes or the specified portions thereof shall be

23

 

paid and redeemed by the Company at the applicable redemption price, together with interest
accrued thereon to, but excluding, the redemption date; provided that if the applicable redemption
date is an interest payment date, the interest payable on such interest payment date shall be
payable to the holders of record of such Notes on the applicable record date instead of the holders
surrendering such Notes for redemption on such date.

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

          Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any notice of
redemption during the continuance of a default in payment of interest or premium, if any, on the
Notes. If any Note called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and premium, if any, shall, until paid or duly provided for, bear
interest from the redemption date at a rate equal to 1% per annum plus the rate borne by the Note
(without duplication of the 1% increase provided for under Section 6.02) and such Note shall remain
convertible into Common Stock or cash until the principal and premium, if any, and interest shall
have been paid or duly provided for.

          Section 3.04. Conversion Arrangement on Call for Redemption. In connection with any
redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an
agreement with one or more investment banks or other purchasers to purchase such Notes by paying to
the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not
less than the applicable redemption price, together with interest accrued to, but excluding, the
date fixed for redemption, of such Notes. Notwithstanding anything to the contrary contained in
this Article 3, the obligation of the Company to pay the redemption price of such Notes, together
with interest accrued to, but excluding, the date fixed for redemption, shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, a copy of which will be filed with the Trustee prior to the date fixed
for redemption, any Notes not duly surrendered for conversion by the holders thereof may, at the
option of the Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary contained in Article 14)
surrendered by such purchasers for conversion, all as of immediately prior to the close of business
on the date fixed for redemption (and the right to convert any such Notes shall be extended through
such time), subject to payment of the above amount as aforesaid. At the direction of the Company,
the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would
monies deposited with it by the Company for the redemption of Notes. Without the Trustee’s prior
written consent, no arrangement between the Company and such purchasers for the purchase and
conversion of any Notes shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture.

Section 3.05(e) hereof, upon the occurrence of a Fundamental Change at any time prior to Maturity,
each holder may require the Company to repurchase such holder’s Notes no less than 20 days and no

     (1) if applicable, whether the Company will elect to adjust the Conversion Rate and
related conversion obligation pursuant to Section 14.06(e) hereof or issue Additional Shares

     (2) whether the Company expects that holders will have the right to require the Company
to repurchase their Notes as described in this Section 3.05; and

     (3) that the holders of the Notes have the right to convert their Notes in accordance
with Section 14.06 hereof.

     (b) On or before the 15th day following the Effective Date of such Fundamental
Change transaction (which Fundamental Change results in the holders of Notes having the right to
cause the Company to repurchase their Notes), the Company shall provide to all holders of the
Notes, the Trustee, the paying agent and the Conversion Agent a notice of the occurrence of the
Fundamental Change and of the resulting repurchase right (the “Fundamental Change Repurchase Right
Notice”) stating:

     (1) the events causing a Fundamental Change;

     (2) if the Company has elected to adjust the Conversion Rate and related conversion
obligation as described in Section 14.06 hereof pursuant to a Fundamental Change that falls
under clause (2), (3) or (4) of the definition of Fundamental Change, the Conversion Rate,
any adjustments to the Conversion Rate and the details of the Public Acquirer Common Stock;

     (3) the Effective Date of the Fundamental Change;

     (4) the last date on which a holder may exercise such repurchase right;

     (5) the Fundamental Change repurchase price;

     (6) the Fundamental Change Repurchase Date;

     (7) the name and address of the paying agent and the Conversion Agent;

25

 

     (8) that the Notes with respect to which the Fundamental Change Repurchase Right Notice
has been given by the holder may be converted only if the holder withdraws the Option to
Elect Repayment Upon a Fundamental Change form included on the reverse of the Note in
accordance with the terms of this Indenture; and

     (9) the procedures that holders must follow to require the Company to repurchase their
Notes.

     Simultaneously with providing such Fundamental Change Repurchase Right Notice, the Company
will issue a press release and publish the information contained in such notice through a public
medium customary for such press releases as well as publish the information on the Company’s
website.

     (c) A holder may exercise its right specified in Section 3.05(a) upon delivery of the Notes to
be repurchased, duly endorsed for transfer with the form entitled “Option to Elect Repurchase Upon
a Fundamental Change” on the reverse thereof duly completed and signed, together with such Notes to
the Trustee (or other paying agent appointed by the Company) at any time prior to 5:00 p.m., New
York City time, on the second Business Day immediately preceding the Fundamental Change Repurchase
Date, stating:

     (1) if certificated, the certificate numbers of the Notes which the holder will deliver
to be repurchased or the rules and procedures of the Depositary if definitive Notes have not
been issued;

     (2) the portion of the principal amount of the Notes which the holder will deliver to
be repurchased, which portion must be in principal amounts of $1,000 or an integral multiple
thereof; and

     (3) that such Notes are to be purchased by the Company as of the Fundamental Change
Repurchase Date pursuant to the terms and conditions specified in the Notes and in this
Indenture.

          The delivery of such Notes (either through the surrender of definitive Notes or through the
delivery of beneficial interests in a Global Note in accordance with the rules and procedures of
the Depositary) to the Trustee (or other paying agent appointed by the Company) with, or at any
time after delivery of, the Fundamental Change Repurchase Right Notice (together with all necessary
endorsements) at the offices of the Trustee (or other paying agent appointed by the Company) shall
be a condition to the receipt by the holder of the Fundamental Change Payment therefor; provided,
however, that such Fundamental Change Payment shall be so paid pursuant to this Section 3.05 only
if the Notes so delivered to the Trustee (or other paying agent appointed by the Company) shall
conform in all respects to the description thereof in the related Repurchase Notice. Any
repurchase by the Company contemplated pursuant to the provisions of this Section 3.05 shall be
consummated by the delivery of the consideration to be received by the holder promptly following
the later of the Fundamental Change Repurchase Date and the time of delivery of the Notes.

          Prior to 10:00 a.m. (New York City Time) on the Business Day following the Fundamental Change
Repurchase Date, the Company shall deposit with the Trustee (or other

26

 

paying agent appointed by the Company, or, if the Company is acting as the paying agent, shall
segregate and hold in trust as provided in Section 4.04) an amount of cash (in immediately
available funds if deposited on such Business Day) sufficient to pay the aggregate purchase price
of all the Notes or portions thereof that are to be purchased as of the Fundamental Change
Repurchase Date.

          If the Trustee holds money or securities sufficient to pay the Fundamental Change Repurchase
Price on the Business Day following the Fundamental Change Repurchase Date, the Notes will cease to
be outstanding and interest, if any, shall cease to accrue on the Notes or portions thereof called
for repurchase on the Fundamental Change Repurchase Date (whether or not book-entry transfer of the
Note is made or whether or not the Note is delivered to the Trustee (or other paying agent
appointed by the Company)) and all other rights of the holders of the Notes to be repurchased
pursuant to this Section 3.05 shall terminate (other than the right to receive the Fundamental
Change Payment upon delivery or transfer of the Notes).

     (d) The Company will comply with the requirements of Rule 13e-4 and Rule 14e-1 under the
Exchange Act, if applicable, including the filing of a Schedule TO if required, and will comply
with the requirements of any other federal and state securities laws and regulations thereunder to
the extent those laws and regulations are applicable in connection with the repurchase of the Notes
by the Company as a result of a Fundamental Change. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this Section 3.05, the Company will
comply with the applicable securities laws and regulations and will not be deemed to have breached
its obligations under this Section 3.05 by virtue of such conflict.

     (e) On the Fundamental Change Repurchase Date, the Company will, to the extent lawful:

     (1) accept for payment all Notes or portions thereof properly tendered;

     (2) deposit with the Trustee (or other paying agent appointed by the Company) an amount
equal to the Fundamental Change Payment in respect of all Notes or portions of Notes
properly tendered; and

     (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with
an Officers’ Certificate stating the aggregate principal amount of Notes or portions of
Notes being purchased by the Company in accordance with the terms of this Section 3.05.

          The Trustee (or other paying agent appointed by the Company) will promptly mail to each holder
of Notes properly tendered the Fundamental Change Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided
that each new Note will be in a principal amount of $1,000 or an integral multiple thereof.

     (f) Notwithstanding anything contained herein to the contrary, holders of the Notes will not
have the right to require the Company to repurchase any Notes pursuant to the occurrence of any of
the events identified in clause (b), (c) or (d) of the definition of

27

 

Fundamental Change (and the Company will not be required to deliver the Fundamental Change
Repurchase Right Notice incidental thereto), if either:

     (1) the Closing Sale Price of the Company’s Common Stock for any five Trading Days
within the period of 10 consecutive Trading Days ending immediately after the later of the
Fundamental Change or the public announcement of the Fundamental Change, in the case of a
Fundamental Change relating to an acquisition of Capital Stock under clause (b) of the
definition of Fundamental Change, or the period of 10 consecutive Trading Days ending
immediately before the Fundamental Change, in the case of a Fundamental Change relating to a
merger, consolidation, asset sale or otherwise under clause (c) of the definition of
Fundamental Change or a change in the Board of Directors under clause (d) of the definition
of Fundamental Change, equals or exceeds 105% of the applicable Conversion Price of the
Notes in effect on each of those five Trading Days; or

     (2) at least 90% of the consideration paid for the Company’s Common Stock (excluding
cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal
rights) in a merger or consolidation or a conveyance, sale, transfer or lease otherwise
constituting a Fundamental Change under clause (b) and/or clause (c) of the definition of
Fundamental Change consists of shares of common stock traded on the New York Stock Exchange
or another U.S. national securities exchange or quoted on The Nasdaq Stock Market or another
established automated over-the-counter trading market in the United States (or will be so
traded or quoted immediately following the merger or consolidation) and, as a result of the
merger or consolidation, the Notes become convertible into such shares of such common stock.

     (g) Upon receipt by the Trustee (or other paying agent appointed by the Company) of the duly
completed Option to Elect Repurchase Upon a Fundamental Change specified in Section 3.05(c) hereof,
the holder of the Notes in respect of which such Repurchase Notice was given shall (unless such
Option to Elect Repurchase Upon a Fundamental Change is withdrawn as specified in Section 3.05(h)
hereof) thereafter be entitled to receive solely the Fundamental Change Payment with respect to
such Notes. Such Fundamental Change Payment shall be paid to such holder, subject to receipts of
cash by the Trustee (or other paying agent appointed by the Company), promptly following the later
of (i) the Fundamental Change Repurchase Date (provided the conditions in Section 3.05(c) have been
satisfied) and (ii) the time of book-entry transfer or the delivery of such Notes to the Trustee
(or other paying agent appointed by the Company) by the holder thereof in the manner required by
Section 3.05(c). Notes in respect of which a duly completed Option to Elect Repurchase Upon a
Fundamental Change has been given by the holder thereof may not be converted pursuant to Article 14
on or after the date of the delivery of such Option to Elect Repurchase Upon a Fundamental Change
unless such Option to Elect Repurchase Upon a Fundamental Change has first been validly withdrawn
as specified in Section 3.05(h) hereof.

     (h) Notwithstanding anything contained herein to the contrary, any holder delivering to the
Trustee (or other paying agent appointed by the Company) the Option to Elect Repurchase Upon a
Fundamental Change contemplated by Section 3.05(c) hereof shall have the right to withdraw such
Option to Elect Repurchase Upon a Fundamental Change, in whole or in part, by means of a written
notice, or electronic notice pursuant to the procedures of the Depositary, of

28

 

     withdrawal delivered to the Trustee (or other paying agent appointed by the Company) at any
time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the
Fundamental Change Repurchase Date, specifying:

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

     (2) the certificate numbers of the definitive Notes, if any, in respect of which such
notice of withdrawal is being submitted; and

     (3) the principal amount, if any, of such Notes which remain subject to the original
Option to Elect Repurchase Upon a Fundamental Change and which have been or will be
delivered for repurchase by the Company.

If the Notes are not in definitive form, the notice of withdrawal must comply with the appropriate
procedures of the Depositary.

          Section 3.06. Repurchase of Notes by the Company at Option of the Holder. Notes shall be purchased
by the Company pursuant to the terms of the Notes at the option of the holder on August 15, 2010,

another paying agent appointed by the Company), such delivery being a condition to receipt
by the holder of the purchase price therefor; provided that such purchase price shall be so
paid pursuant to this Section 3.06 only if the Note so delivered to the Trustee (or other
paying agent appointed by the Company) shall conform in all respects to the description
thereof in the related Repurchase Notice.

          The Company shall purchase from the holder thereof, pursuant to this Section 3.06, a portion
of a Note, if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase

appointed by the Company) of the Repurchase Notice specified in Section 3.06, the holder of the
Note in respect of which such Repurchase Notice, was given shall (unless such Repurchase Notice is

(in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate
purchase price of all the Notes or portions thereof that are to be purchased as of the Repurchase

case may be, exceeds the aggregate purchase price of the Notes or portions thereof which the
Company is obligated to purchase as of the Fundamental Change Repurchase Date, or the Repurchase

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 not
designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such

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.

mailed, the notices set forth in Section 7.10(b) and the third paragraph of Section 7.11. If
co-registrars have been appointed in accordance with this Section 4.02, the Trustee shall mail such
notices only to the Company and the holders of Notes it can identify from its records.

          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

          Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a paying agent
other than the Trustee, or if the Trustee shall appoint such a paying agent, 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 of, or premium, if any, or interest on, the Notes (whether such sums have been
paid to it by the Company or by any other obligor on the Notes) in trust for the benefit of
the holders of the Notes;

     (ii) that it will give the Trustee written notice of any failure by the Company (or by
any other obligor on the Notes) to make any payment of the principal of, or premium, if any,
or 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 of, or premium if any, or
interest on, the Notes, deposit with the paying agent a sum (in funds which are immediately
available on the due date for such payment) sufficient to pay such principal, premium, if any, or
interest, and (unless such paying agent is the Trustee) the Company will promptly notify the
Trustee in writing of any failure to take such action; provided that if such deposit is made on the
due date, such deposit shall be received by the paying agent by 10:00 a.m. New York City time, on
such date.

          (b) If the Company shall act as the paying agent, it will, on or before each due date of the
principal of, or premium, if any, or 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, premium, if
any, or interest so becoming due, will account for any funds disbursed by it and will promptly
notify the Trustee of any failure to take such action and of any failure by the Company (or any
other obligor under the Notes) to make any payment of the principal of, or premium, if any, or
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 or cause to be paid to the Trustee all sums held in trust by the Company or any paying
agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent to the Trustee,
the Company or such paying agent shall be released from all further liability with respect to such
sums.

          (d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 4.04 is subject to Sections 12.03 and 12.04.

          The Trustee shall not be responsible for the actions of any other paying agents (including the
Company if acting as the paying agent) and shall have no control of any funds held by such other
paying agents.

          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 effect its corporate existence.

          Section 4.06. Maintenance of Properties. The Company will cause all properties used or useful in
the conduct of its business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided that nothing in this
Section 4.06 shall prevent the Company from discontinuing the operation or maintenance of, or
disposing of, any of such properties if such discontinuance or disposal is, in the judgment of the
Company, desirable in the conduct of its business or the business of any Subsidiary and not
disadvantageous in any material respect to the Noteholders.

34

 

          Section 4.07. Payment of Taxes and Other Claims. The Company will pay or discharge, or cause
to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and
governmental charges levied or imposed upon the Company or any of its Subsidiaries or upon the
income, profits or property of the Company or any of its Subsidiaries, (ii) all claims for labor,
materials and supplies which, if unpaid, might by law become a lien or charge upon the property of
the Company or any of its Subsidiaries and (iii) all stamp taxes and other duties, if any, which
may be imposed by the United States or any political subdivision thereof or therein in connection
with the issuance, transfer, exchange, conversion, redemption or repurchase of any Notes or with
respect to this Indenture; provided that, in the case of clauses (i) and (ii), the Company shall
not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in good faith and for
which adequate reserves have been established in accordance with generally accepted accounting
principles and which if unpaid would reasonably not be expected to result in a material adverse
effect on the business, results of operations, or financial condition of the Company and its
Subsidiaries, taken as a whole.

          Section 4.08. Rule 144A Information Requirement. Within the period prior to the expiration of
the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), the Company covenants and agrees that it shall, during any period in which it
is not subject to Section 13 or 15(d) under the Exchange Act, provide to the Trustee and make
available to any holder or beneficial holder of Notes or any Common Stock issued upon conversion
thereof which continue to be Restricted Securities in connection with any sale thereof and any
prospective purchaser of Notes or such Common Stock designated by such holder or beneficial holder,
the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of
any holder or beneficial holder of the Notes or such Common Stock and it will take such further
action as any holder or beneficial holder of such Notes or such Common Stock may reasonably
request, all to the extent required from time to time to enable such holder or beneficial holder to
sell its Notes or Common Stock without registration under the Securities Act within the limitation
of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the
request of any holder or any beneficial holder of the Notes or such Common Stock, the Company will
deliver to such holder a written statement as to whether it has complied with such requirements.
Delivery of such information to the Trustee is for informational purposes only and the Trustee’s
receipt of such shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s compliance with any of its
covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’
Certificates).

          Section 4.09. 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 which
would prohibit or forgive the Company from paying all or any portion of the principal of, or
premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any
time hereafter in force, or which 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,

35

 

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 4.10. Compliance Certificate; Notice of Default. The Company shall deliver to the
Trustee, within one hundred twenty (120) days after the end of each fiscal year of the Company, an
Officers’ Certificate stating whether or not to the best knowledge of the signers thereof the
Company is in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Company shall be in default, specifying all such defaults and the
nature and the status thereof of which the signer may have knowledge.

          The Company will deliver to the Trustee, as soon as possible after the Company becomes aware
of any Event of Default or an event which, with notice or the lapse of time or both, would
constitute an Event of Default, an Officers’ Certificate setting forth the details of such default
or Event of Default and the action that the Company has taken, is taking or proposes to take with
respect thereto.

          Any notice required to be given under this Section 4.10 shall be delivered to a Responsible
Officer of the Trustee at its Corporate Trust Office.

          Section 4.11. Maintenance of Insurance. The Company shall keep at all times all of their
properties which are of an insurable nature insured against loss or damage, and to maintain
liability insurance, with insurers believed by the Company to be responsible to the extent that
property of similar character is usually so insured, or liability insurance usually is so
maintained, by corporations similarly situated and owning like properties in accordance with good
business practice.

          Section 4.12. Liquidated Damages Notice. In the event that the Company is required to pay
Liquidated Damages to holders of Notes pursuant to the Registration Rights Agreement, the Company
will provide an Officers’ Certificate (“Liquidated Damages Notice”) to the Trustee notifying the
Trustee of its obligation to pay Liquidated Damages no later than fifteen (15) days prior to the
proposed payment date for the Liquidated Damages, and the Liquidated Damages Notice shall set forth
the amount of Liquidated Damages to be paid by the Company on such payment date. The Trustee shall
not at any time be under any duty or responsibility to any holder of Notes to determine the
Liquidated Damages, or with respect to the nature, extent or calculation of the amount of
Liquidated Damages when made, or with respect to the method employed in such calculation of the
Liquidated Damages.

ARTICLE V

          Section 5.01. Company to Furnish Trustee Names and Addresses of Noteholders. The Company
covenants and agrees that it will furnish or cause to be furnished to the Trustee, semiannually,
not more than fifteen (15) days after each February 15 and August 15 in each year beginning with
August 15, 2005, and at such other times as the Trustee may request in writing, within thirty (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

36

 

provided by it hereunder), a list in such form as the Trustee may reasonably require of the
names and addresses of the registered holders of Notes as of a date not more than fifteen (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 by the
Company to the Trustee so long as the Trustee is acting as the sole Note registrar.

          Section 5.02. Preservation and Disclosure of Lists. (a) The Trustee shall preserve, in as
current a form as is reasonably practicable, all information as to the names and addresses of the
holders of Notes 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 or co-registrar in respect of the
Notes, 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.

          (b) The rights of Noteholders to communicate with other holders of Notes with respect to their
rights under this Indenture or under the Notes, and the corresponding rights and duties of the
Trustee, shall be as provided by the Trust Indenture Act.

          (c) Every Noteholder, by receiving and holding the same, agrees with the Company and the
Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of any disclosure of information as to names and addresses of holders of
Notes made pursuant to the Trust Indenture Act.

          Section 5.03. Reports by Trustee. (a) Within sixty (60) days after December 30 of each year
commencing with the year 2005, the Trustee shall transmit to holders of Notes such reports dated as
of December 30 of the year in respect of which such reports are made concerning the Trustee and its
actions under this Indenture as shall be required, if any, pursuant to the Trust Indenture Act at
the times and in the manner provided pursuant thereto.

          (b) A copy of such report shall, at the time of such transmission to holders of Notes, be
filed by the Trustee with each stock exchange and automated quotation system upon which the Notes
are listed and with the Company. The Company will promptly notify the Trustee in writing when the
Notes are listed on any stock exchange or automated quotation system or delisted therefrom.

          Section 5.04. Reports by Company. The Company shall file with the Trustee and transmit to
holders of the Notes, such information, documents and other reports as it is required to file with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act within 15 days after the same is
so required to be filed with the Commission. Delivery of such reports, information and documents
to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not
constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

ARTICLE VI

Remedies of the Trustee and Noteholders on an Event of Default

          Section 6.01. Events of Default; Acceleration. In case one or more of the following Events of
Default (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) shall have
occurred and be continuing:

     (a) default in the payment of any installment of interest with respect to any of the
Notes as and when the same shall become due and payable, and continuance of such default for
a period of thirty (30) days; or

     (b) default in the payment of the principal of or premium, if any, or any of the Notes
as and when the same shall become due and payable either at Maturity or in connection with
any redemption or repurchase, in each case pursuant to Article 3, by acceleration or
otherwise; or

     (c) failure on the part of the Company duly to observe or perform any other of the
covenants or agreements on the part of the Company in the Notes or in this Indenture (other
than a covenant or agreement a default in whose performance or whose breach is elsewhere in
this Section 6.01 specifically dealt with) continued for a period of sixty (60) days after
the date on which written notice of such failure, requiring the Company to remedy the same,
shall have been given to the Company by the Trustee, or the Company and a Responsible
Officer of the Trustee by the holders of at least twenty-five percent (25%) in aggregate
principal amount of the Notes at the time outstanding determined in accordance with Section
8.04; or

     (d) a default or defaults under the terms of any bond(s), debenture(s), note(s) or
other evidence(s) of, or under any mortgage(s), indenture(s), agreement(s) or instrument(s)
under which there may be issued or by which there may be secured or evidenced, any
indebtedness of the Company or any of its Subsidiaries with a principal amount then
outstanding, individually or in the aggregate, of at least $10,000,000, whether such
indebtedness now exists or is hereafter incurred, which default or defaults (i) shall have
resulted in such indebtedness becoming or being declared due and payable prior to the date
on which it would otherwise have become due and payable or (ii) shall constitute the failure
to pay such indebtedness at the final stated Maturity thereof (after expiration of any
applicable grace period) and such default shall not have been rescinded or such indebtedness
shall not have been discharged within 10 days; or

     (e) the entry by a court having jurisdiction in the premises of (A) a decree or order
for relief in respect of the Company in an involuntary case or proceeding under any
applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or
(B) a decree or order adjudging the Company as bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or composition of
or in respect of the Company under any applicable Federal or State law, or appointing a
custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official
of

38

 

the Company or of any substantial part of the property of the Company, or ordering the
winding up or liquidation of the affairs of the Company, and the continuance of any such
decree or order for relief or any such other decree or order unstayed and in effect for a
period of 60 consecutive days; or

     (f) the commencement by the Company of a voluntary case or proceeding under any
applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or
of any other case or proceeding to be adjudicated as bankrupt or insolvent, or the consent
by the Company to the entry of a decree or order for relief in respect of the Company in an
involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or insolvency
case or proceeding against the Company or the filing by the Company of a petition or answer
or consent seeking reorganization or relief under any applicable Federal or State law, or
the consent by the Company to the filing of such a petition or to the appointment of or
taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or
similar official of the Company or of any substantial part of the property of the Company,
or the making by the Company of an assignment for the benefit of creditors, or the admission
by the Company in writing of its inability to pay its debts generally as they become due, or
the taking of corporate action by the Company in furtherance of any such action;

then, and in each and every such case (other than an Event of Default specified in Section 6.01(e)
or 6.01(f) that occurs with respect to the Company), unless the principal of all of the Notes shall
have already become due and payable, either the Trustee or the holders of not less than twenty-five
percent (25%) in aggregate principal amount of the Notes then outstanding hereunder determined in
accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by
Noteholders) specifying the respective Event of Default and stating that it is a “notice of
acceleration”, may declare the principal of and premium, if any, on all the Notes and the interest
accrued thereon to be due and payable immediately, and upon receipt of such notice the same shall
become and shall be immediately due and payable. If an Event of Default specified in Section
6.01(e) or 6.01(f) involving the Company occurs, the principal of all the Notes and the interest
accrued thereon shall be immediately and automatically due and payable without necessity of further
action. 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 all
matured installments of interest upon all Notes and the principal of, and premium, if any on any
and all Notes which shall have become due otherwise than by acceleration (with interest on overdue
installments of interest (to the extent that payment of such interest is enforceable under
applicable law) and on such principal and premium, if any, at the rate borne by the Notes plus 1%,
to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 7.07,
and if any and all defaults under this Indenture, other than the nonpayment of principal of, and
premium, if any, and accrued interest on, Notes which shall have become due by acceleration, shall
have been cured or waived pursuant to Section 6.07, 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 and rescind and annul such
declaration and its consequences; but no such

39

 

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. In accordance with Section 4.10, the
Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware
thereof, of any Event of Default or any event which, with notice or the lapse of time or both,
would constitute an Event of Default.

          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 of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding
had been taken.

          Section 6.02. Payments of Notes on Default; Suit Therefor. The Company covenants that (a) in
case default shall be made in the payment of any installment of interest upon any of the Notes as
and when the same shall become due and payable, and such default shall have continued for a period
of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or
premium, if any, on any of the Notes as and when the same shall have become due and payable,
whether at Maturity of the Notes or in connection with any redemption or repurchase, by or under
this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee,
for the benefit of the holders of the Notes, the whole amount that then shall have become due and
payable on all such Notes for principal, premium, if any, or interest, as the case may be, with
interest upon the overdue principal and premium, if any, and (to the extent that payment of such
interest is enforceable under applicable law) upon the overdue installments of interest at the rate
borne by the Notes, plus 1% and, in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to the Trustee, its
agents, attorneys and counsel, and all other amounts due the Trustee under Section 7.07. Until
such demand by the Trustee, the Company may pay the principal of, and premium, if any, and interest
on, the Notes to the registered holders, whether or not the Notes are overdue.

          In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and
may prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes and collect in the
manner provided by law out of the property of the Company or any other obligor on the Notes
wherever situated the monies adjudged or decreed to be payable.

          In case 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
case 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

40

 

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 6.02, 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, premium, if any, and interest owing and unpaid in respect of the
Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee, its agents
and its counsel and of the Noteholders 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 7.07, and any
receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar
official is hereby authorized by each of the Noteholders to make such payments to the Trustee, and,
in the event that the Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses,
advances and disbursements, including counsel fees and expenses incurred by it up to the date of
such distribution.

          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.

          Section 6.03. Application of Monies Collected by Trustee. Any monies or other compensation
collected by the Trustee pursuant to this Article 6 shall be applied in the order following, at the
date or dates fixed by the Trustee for the distribution of such monies or other compensation, 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 7.07;

     SECOND: In case the principal of the outstanding Notes shall not have become due and
be unpaid, to the payment of interest on the Notes in default in the order of the Maturity
of the installments of such interest, with interest (to the extent that such interest has
been collected by the Trustee) upon the overdue installments of interest at the rate borne
by the Notes plus 1%, such payments to be made ratably to the Persons entitled thereto;

41

 

     THIRD: In case the principal of the outstanding Notes shall have become due, by
declaration or otherwise, and be unpaid to the payment of the whole amount then owing and
unpaid upon the Notes for principal and premium, if any, and interest, with interest on the
overdue principal and premium, if any, 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 plus 1% to the Persons entitled thereto, 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, premium, if any, and interest without preference or priority of principal
and premium, if any, over interest, or of interest over principal and premium, if any, 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 and premium, if any, and accrued and
unpaid interest; and

     FOURTH: To the payment of the remainder, if any, to the Company or any other Person
lawfully entitled thereto.

          Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue
of or by reference to any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon 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 such holder previously shall have given to the Trustee written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of
not less than twenty-five percent (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 and shall have offered to the Trustee such reasonable indemnity
as it may require against the costs, expenses and liabilities to be incurred therein or thereby,
and the Trustee for sixty (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 no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 6.07; 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
of Notes shall have any right in any manner whatever by virtue of or by reference to any provision
of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, 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 of Notes (except as otherwise provided herein). For the protection
and enforcement of this Section 6.04, each and every Noteholder 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 of any Note to receive payment of the principal of, and premium, if any (including
the redemption or repurchase price upon redemption or repurchase pursuant to Article 3), and
accrued interest on, such Note, on or after the respective due dates expressed in such Note or in
the case of a redemption or repurchase, on the redemption date or Repurchase Date, as the case may
be, or to institute suit for the enforcement of any such payment on or after such respective dates
against the Company shall not be impaired or affected without the consent of such holder.

42

 

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

          Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its
discretion, but shall not be required to, 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 6.06. Remedies Cumulative and Continuing. Except as provided in Section 2.06, all
powers and remedies given by this Article 6 to the Trustee or to the Noteholders 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 occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such
default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power
and remedy given by this Article 6 or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

          Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. 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 for exercising any trust or power
conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule
of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent
with such direction and (c) the Trustee may decline to take any action that the Trustee determines
in its reasonable discretion would benefit some Noteholder to the detriment of other Noteholders or
of the Trustee. 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 or existing default or Event of Default hereunder and its consequences except
(i) a past or existing default in the payment of interest or premium, if any, on, or the principal
of, the Notes (including in connection with an offer to purchase); provided, however, that holders
of a majority in aggregate principal amount of the then outstanding Notes may rescind an
acceleration and its consequences, including any related payment default that resulted from such
acceleration in accordance with Section 6.01, (ii) a failure by the Company to convert any Notes
into Common Stock, cash or a combination of cash and Common Stock, (iii) a default in the payment
of the redemption price pursuant to Article 3, (iv) a default in the payment of the purchase price
pursuant to Article 3 or (v) a default in respect of a covenant or provisions hereof which under
Article 10 cannot be modified or

43

 

amended without the consent of the holders of each or all Notes then outstanding or affected
thereby. 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 cured or waived as permitted by this
Section 6.07, 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 for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default
or impair any right consequent thereon.

          Section 6.08. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder
of any Note by his 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 6.08
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Noteholder, or group of Noteholders, 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 Noteholder for the enforcement of the payment of the principal of,
or premium, if any, or interest on, any Note on or after the due date expressed 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.

The Trustee

          Section 7.01. Certain Duties and Responsibilities. The duties and responsibilities of the
Trustee shall be as provided by the Trust Indenture Act (as if such Act applied). Notwithstanding
the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording protection to the
Trustee shall be subject to the provisions of this Section 7.01.

          Section 7.02. Notice of Defaults. Subject to the provisions of Section 7.03(i), the Trustee
shall give the Noteholders notice of any default hereunder known to the Trustee as and to the
extent provided by the Trust Indenture Act (as if such Act applied); provided, however, that except
in the case of default in the payment of the principal of, or premium, if any, or interest on, any
of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust
committee of directors and/or Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Noteholders.

     (a) the Trustee may conclusively rely and shall be protected in acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or document
believed by it in good faith to be genuine and to have been signed or presented by the
proper party or parties;

Company;

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

matter that is reasonably satisfactory to the Trustee;

     (d) the Trustee may consult with counsel of its selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

     (e) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Noteholders
pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to
the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses
(including reasonable attorney’s fees and expenses) and liabilities which might be incurred
by it in compliance with such request or direction; any permissive right or power available
to the Trustee under this Indenture shall not be construed to be a mandatory duty or
obligation;

     (f) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may, but shall not be required
to, make such further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or investigation, it shall
be entitled to examine the books, records and premises of the Company, personally or by
agent or attorney;

     (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee

45

 

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

     (h) the Trustee shall not be liable for any action taken, suffered, or omitted to be
taken by it in good faith, in reliance on an Officers’ Certificate or otherwise, and
reasonably believed by it to be authorized or within the discretion or rights or powers
conferred upon it by this Indenture or for any action it takes or omits to take in
accordance with the direction of the holders of a majority in principal amount of the
outstanding Notes; in no event shall the Trustee be liable to any person for special,
indirect, consequential or punitive damages or any damages for lost profits;

     (i) the Trustee shall not be deemed to have knowledge of any default or Event of
Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event which is in fact such a default is received by the Trustee at
the Corporate Trust Office of the Trustee, and such notice references the Notes and this
Indenture; and

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

          Section 7.04. Not Responsible for Statements or Issuance of Notes. The statements contained
herein and in the 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 their correctness. The
Trustee makes no representations as to the validity or sufficiency of this Indenture and the Notes.
The Trustee shall not be accountable for the use or application by the Company of any Notes or the
proceeds thereof.

          Section 7.05. May Hold Notes. The Trustee, any authentication agent, any paying agent, any
Conversion Agent, any Note registrar or any other agent of the Company or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes, and, subject to
Sections 7.08 and 7.13, may otherwise deal with the Company and any other obligor upon the Notes
with the same rights it would have if it were not Trustee, authentication agent, paying agent,
Conversion Agent or Note registrar.

          Section 7.06. Monies to Be Held in Trust. Money held by the Trustee in trust hereunder need
not be segregated from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed in
writing with the Company.

          Section 7.07. Compensation and Reimbursement. The Company agrees (1) to pay to the Trustee
from time to time such compensation as shall be agreed in writing between the Company and the
Trustee for all services rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust); (2) except as
otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in

46

 

accordance with any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense, disbursement or
advance as may be attributable to its negligence or willful misconduct; and (3) to indemnify each
of the Trustee and any predecessor Trustee for, and to hold it harmless against, any and all loss,
liability, damage, claim or expense, including taxes (other than taxes based on the income of the
Trustee) incurred without negligence or willful misconduct on its part, arising out of or in
connection with the acceptance or administration of this trust, including the costs and expenses,
including reasonable attorney’s fees and expenses, of defending itself against any claim (whether
asserted by the Company, a Noteholder or any other Person) or liability, or of complying with any
process served upon it or any of its officers, in connection with the exercise or performance of
any of its powers or duties hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel.

          The Trustee shall have a lien prior to the Notes as to all property and funds held by it
hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 7.07, except
with respect to funds held in trust for the benefit of the holders of particular Notes.

          When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 6.01(e) or 6.01(f), the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to constitute expenses
of administration under any applicable Federal or State bankruptcy, insolvency or other similar
law.

          Section 7.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the
provisions of, this Indenture.

          Section 7.09. Corporate Trustee Required; Eligibility. 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 $150,000,000 and has its Corporate Trust
Office located in the Borough of Manhattan, The City of New York. If such Person publishes reports
of condition at least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section 7.09, 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 7.09, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article 7.

          Section 7.10. Resignation and Removal of Trustee; Appointment of Successor. (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this
Article 7 shall become effective until the acceptance of appointment by the successor Trustee under
Section 7.11.

          (b) The Trustee may resign at any time by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to

47

 

the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of a successor
Trustee.

          (c) The Trustee may be removed at any time by act of the holders of a majority in principal
amount of the outstanding Notes, delivered to the Trustee and the Company. If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition any court of competent
jurisdiction for the appointment of a successor.

          (d) If at any time:

     (i) the Trustee shall fail to comply with Section 7.08 after written request therefor
by the Company or by any Noteholder who has been a bona fide holder of a Note for at least
six months, or

     (ii) the Trustee shall cease to be eligible under Section 7.09 and shall fail to resign
after written request therefor by the Company or by any such Noteholder, or

     (iii) 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 any such case, the Company may 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 6.08, any Noteholder who has been a bona fide holder of a Note
or Notes for at least six (6) 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.

          (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, the Company, by a resolution of the Board of
Directors, shall promptly appoint a successor Trustee. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed
by act of the holders of a majority in principal amount of the outstanding Notes delivered to the
Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed by the Company or
the holders and accepted appointment in the manner hereinafter provided, any Noteholder who has
been a bona fide holder of a Note for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the appointment of a successor
Trustee.

          (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor Trustee to all holders in the manner provided in Section 15.03. Each
notice shall include the name of the successor Trustee and the address of its Corporate Trust
Office.

48

 

     (g) Notwithstanding replacement of the Trustee pursuant to this Section 7.10, the Company’s
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

          Section 7.11. Acceptance of Appointment of Successor. Every successor Trustee appointed
hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring
Trustee; but, on written request of the Company or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by such retiring Trustee
hereunder. Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

          No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible under this Article 7.

          Upon acceptance of appointment by a successor Trustee as provided in this Section 7.11, the
Company (or the former Trustee, at the written direction of the Company) shall mail or cause to be
mailed notice of the succession of such Trustee hereunder to the holders of Notes at their
addresses as they shall appear on the Note register, which notice shall include the address of the
Corporate Trust Office of such successor Trustee. If the Company fails to mail such notice within
ten (10) 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 7.12. Merger, Conversion, Consolidation or Succession to Business. Any corporation
into which the Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate trust business of
the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article 7, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such authentication and
deliver the Notes so authenticated with the same effect as if such successor Trustee had itself
authenticated such Notes.

          Section 7.13. Preferential Collection of Claims Against Company. If and when the Trustee
shall be or become a creditor of the Company or any other obligor upon the Notes, the Trustee shall
be subject to the provisions of the Trust Indenture Act (as if such Act applied) regarding the
collection of the claims against the Company or any such other obligor.

49

 

ARTICLE VIII

The Noteholders

          Section 8.01. Action by Noteholders. 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 Noteholders in person or by agent or proxy appointed in
writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of
Noteholders 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 Noteholders.
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 in advance of such solicitation, a date as the record date for
determining holders entitled to take such action. The record date shall be not more than fifteen
(15) days prior to the date of commencement of initial solicitation of such action without giving
effect to any extension or amendment of such action or solicitation.

          Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.03
and 9.05, proof of the execution of any instrument by a Noteholder 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 satisfactory to the Trustee. The holding of Notes shall
be proved by the registry of such Notes or by a certificate of the Note registrar.

          The record of any Noteholders’ 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 such 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 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 premium, if any, and
interest on, such Note, for conversion of such Note and for all other purposes; and neither the
Company nor the Trustee nor any authenticating agent, 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 his 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.

          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 which are owned by the Company or any other obligor on the
Notes or any Affiliate of the Company or any other obligor on the Notes 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

50

 

on any such direction, consent, waiver or other action, only Notes which a Responsible Officer
knows are so owned shall be so disregarded. Notes so owned which 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 vote such Notes and that the pledgee is
not the Company, any other obligor on the Notes or any Affiliate of the Company or any such other
obligor. In the case of a dispute as to such right, any good faith 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 7.03, 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 which 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 a continuing action and 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, irrespective of whether any notation in regard thereto is made upon such
Note or any Note issued in exchange or substitution therefor. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every holder.

ARTICLE IX

          Section 9.01. Purpose of Meetings. A meeting of Noteholders may be called at any time and

the Trustee permitted under this Indenture, or to consent to the waiving of any default or
Event of Default hereunder and its consequences, or to take any other action authorized to

     (b) to remove the Trustee and nominate a successor Trustee pursuant to the provisions
of Article 7;

51

 

     (d) to take any other action authorized to be taken by or on behalf of the holders of
any specified aggregate principal amount of the Notes under any other provision of this
Indenture or under applicable law.

          Section 9.02. Call of Meetings by Trustee. The Trustee may at any time call a meeting of
Noteholders 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 Noteholders, 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
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 (20) nor more than ninety
(90) days prior to the date fixed for the meeting.

          Any meeting of Noteholders 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 Noteholders. In case at any time the Company,
pursuant to a resolution of its Board of Directors, or the holders of at least twenty-five (25%) in
aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call
a meeting of Noteholders, 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
twenty (20) days after receipt of such request, then the Company or such Noteholders 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 Noteholders
a person shall (a) be a holder of one or more Notes on the record date pertaining to such meeting
or (b) be a person appointed by an instrument in writing as proxy by a holder of one or more Notes
on the record date pertaining to such meeting. The only persons who shall be entitled to be
present or to speak at any meeting of Noteholders 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
Noteholders, 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 Noteholders as provided in Section
9.03, in which case the Company or the Noteholders calling the meeting, as the case may be, shall
in like manner appoint a temporary chairman. A permanent chairman and

52

 

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 except
that any meeting called by the Company shall be chaired by a representative of the Company and any
meeting called by the Trustee may, at the Trustee’s election, be chaired by the Trustee.

          Subject to the provisions of Section 8.04, at any meeting each Noteholder or proxyholder shall
be entitled to one vote for each $1,000 principal amount of Notes held or represented by him. If
any vote cast or counted or proposed to be cast or counted is challenged on the ground that such
Note is not outstanding, or does not comply with the provisions of Section 9.04, the chairman of
the meeting shall determine whether the holder of such Note is authorized to act. The chairman of
the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in
writing as aforesaid duly designating him as the proxy to vote on behalf of other Noteholders. Any
meeting of Noteholders duly called pursuant to the provisions of Section 9.02 or 10.02 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 Noteholders
shall be by written ballot on which shall be subscribed the signatures of the holders of Notes or
of their representatives by proxy and the 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 be representatives of the Trustee, and 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 Noteholders 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,
absent manifest error.

          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 Noteholders 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 Noteholders
under any of the provisions of this Indenture or of the Notes.

ARTICLE X

Supplemental Indentures

          Section 1.01. Supplemental Indentures Without Consent of Noteholders. The Company, when
authorized by the resolutions of the Board of Directors, and the Trustee 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 evidence the succession of another Person to the Company and the assumption by
any such successor of the covenants of the Company herein and in the Notes; or

surrender any right or power herein conferred upon the Company; or

     (c) to evidence or provide for the acceptance of appointment hereunder by a successor
Trustee with respect to the Notes; or

     (d) to cure any ambiguity, defect or inconsistency or make any change necessary to

the provisions of this Indenture; or

     (e) to add to, change or eliminate any of the provisions of this Indenture to permit or
facilitate the issuance of Global Notes and matters related thereto, provided that such
action pursuant to this clause (e) shall not adversely affect the interests of the holders
in any material respect; or

and assignment of any property thereunder, but the Trustee shall not be obligated to, but may
in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights,
duties or immunities 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.

of the Notes at the time outstanding, the Company, when authorized by the resolutions of the Board
of Directors, and the Trustee 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 of the Notes; provided that no such supplemental
indenture shall (i) extend the fixed maturity of any Note or reduce the rate or extend the time of
payment of interest or additional amounts if any thereon or reduce the principal amount thereof or
premium, if any, thereon or reduce any amount payable on redemption or repurchase thereof or impair
the right of any Noteholder to institute suit for the payment thereof or make the principal thereof
or interest or premium, if any, thereon payable in any coin or currency or payable at any place
other than that provided in this Indenture or the Notes, or change the obligation of the Company to
redeem any Note on a redemption date in a manner adverse to the holders of Notes or change the
obligation of the Company to redeem any Note upon the happening of a Fundamental Change in a manner
adverse to the holders of Notes or change the obligation of the Company to redeem or repurchase any
Note on a Repurchase Date in a manner adverse to the holders of Notes or reduce the Conversion
Rate, otherwise than in accordance with the terms of this Indenture, or impair the right to convert
the Notes into Common Stock or reduce the number of shares of Common Stock, the amount of cash or
the amount of any other property receivable by any holder upon conversion subject to the terms set
forth herein, including Section 14.07 or reduce the quorum or the voting requirements under the
Indenture, or modify any of the provisions of this Section 10.02 or Section 6.07, except to
increase any such percentage or to provide that certain other provisions of this Indenture cannot
be modified or waived without the consent of the holder of each Note so affected, or change any
obligation of the Company to maintain an office or agency in the places and for the purposes set
forth in Section 4.01, in each case, without the consent of the holder of each Note so affected or
(ii) reduce the aforesaid percentage of Notes, the holders of which are required to consent to any
such supplemental indenture or to waive any past Event of Default, without the consent of the
holders of all Notes affected thereby.

          Subject to Section 10.05, upon the written request of the Company, accompanied by a copy of
the resolutions of the Board of Directors certified by its Secretary or Assistant Secretary
authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee
of evidence of the consent of Noteholders as aforesaid, 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 or immunities 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.

55

 

          It shall not be necessary for the consent of the Noteholders under this Section 10.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

          Section 10.03. Effect of Supplemental Indenture. 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 Indenture of the Trustee, the Company and the holders
of Notes 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 bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of
the Trustee and the Company, 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 15.11) 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 to Trustee.
Prior to entering into any supplemental indenture, the Trustee may request an Officers’ Certificate

theretofore authenticated (other than any Notes that have been destroyed, lost or
stolen and in lieu of or in substitution for which other Notes shall have been
authenticated and delivered) and not theretofore canceled, or

     (ii) all the Notes not theretofore canceled or delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become due
and payable within one year or are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption, and

above, Articles 2, 3, 12 and 14 and Sections 4.01, 4.02, 7.01 and 7.03 through 7.12 shall survive
until no Note remains outstanding). The rights, obligations and immunities of the Trustee
hereunder shall survive any discharge pursuant to this Section 12.01, and Section 7.07 shall
survive the termination of this Indenture. The Trustee, on written demand of the Company
accompanied by the aforementioned Officers’ Certificate and an Opinion of Counsel shall, at the
cost and expense of the Company, execute proper instruments acknowledging the satisfaction and
discharge of this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any
costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the
Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection
with this Indenture or the Notes.

          Section 12.02. Deposited Monies to Be Held in Trust by Trustee. Subject to Section 12.04, all
monies deposited with the Trustee pursuant to Section 12.01, shall be held in trust for the sole
benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either
directly or through any paying agent (including the Company if acting as the paying agent), to the
holders of the particular Notes for the payment or redemption of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if
any, and interest.

          Section 12.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this
Indenture, all monies then held by any paying agent of the Notes (other than the Trustee) shall,
upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such
paying agent shall be released from all further liability with respect to such monies.

          Section 12.04. Return of Unclaimed Monies. Subject to the requirements of applicable law and
this Indenture, any monies deposited with or paid to the Trustee for payment of the principal of,
or premium, if any, or interest on, Notes and not applied but remaining unclaimed by the holders of
Notes for two years after the date upon which the principal of, or premium, if any, or interest on,
such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company
by the Trustee on demand and all liability of the Trustee shall thereupon cease with respect to
such monies; and the holder of any of the Notes shall thereafter look only to the Company for any
payment that such holder may be entitled to collect unless an applicable abandoned property law
designates another Person.

          Section 12.05. Reinstatement. If the Trustee or the paying agent is unable to apply any money
in accordance with Section 12.02 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Notes shall be revived and reinstated as

58

 

though no deposit had occurred pursuant to Section 12.01 until such time as the Trustee or the
paying agent is permitted to apply all such money in accordance with Section 12.02; provided that
if the Company makes any payment of interest on or principal of any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of
such Notes to receive such payment from the money held by the Trustee or paying agent.

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, or
because of the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present
or future, of the Company or of any successor corporation, either directly or through the Company

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.

Conversion of Notes

          Section 14.01. Right to Convert. (a) Subject to and upon compliance with the provisions of
this Indenture, the holder of any Note shall have the right, at such holder’s option, to convert
the principal amount of the Note, or any portion of such principal amount which is a multiple of
$1,000, into fully paid and non-assessable shares of Common Stock (as such shares shall then be
constituted) at the Conversion Rate in effect at such time, by surrender of the Note so to be
converted in whole or in part, together with any required funds under the circumstances described
in this Section 14.01, in the manner provided in Section 14.02. The Notes shall be convertible
only upon the occurrence of one of the following events:

     (i) during any fiscal quarter commencing after September 30, 2005, if the Closing Sale
Price exceeds 120% of the Conversion Price for at least 20 Trading Days in the 30
consecutive Trading Day period ending on the last Trading Day of the immediately preceding
fiscal quarter (it being understood for purposes of this Section 14.01(a)(i) that the
Conversion Price in effect at the close of business on each of the 30 consecutive Trading
Days should be used and such calculation shall give effect to any event referred to in
Section 14.06 or 14.07 occurring during such 30 Trading Day period);

     (ii) prior to July 15, 2010, during the five Business Day period immediately after any
five consecutive Trading Day period in which the Trading Price per $1,000 principal amount
of the Notes for each day of such five consecutive Trading Day period was less than 98% of
the product of the Closing Sale Price on the applicable date and the Conversion Rate;

59

 

     (iii) at any time on or after July 15, 2010; or

     (iv) as provided in Section 14.01(b) hereof.

          Upon receipt by the Conversion Agent of a demand for conversion from a Noteholder pursuant to
clause (i) of this Section, the Conversion Agent shall inform the Company of such request and the
Company shall thereupon furnish to the Conversion Agent an Officer’s Certificate stating whether
the Notes are then convertible pursuant to clause (i) of this Section and setting forth in
reasonable detail the Company’s basis for such determination. Upon receipt of such Officer’s
Certificate, if the Company has determined that the Notes are then convertible in accordance with
clause (i) of this Section, the Conversion Agent shall, based solely on its review of the
information contained in such Officer’s Certificate, confirm or refute the Company’s determination.
If the Conversion Agent shall confirm that the Notes are then convertible pursuant to clause (i)
of this Section, then the Conversion Agent shall promptly deliver written notice thereof to the
Company (and, if the Conversion Agent is other than the Trustee, to the Trustee). In any event,
the Company shall be obligated at all times to determine whether the Notes shall be convertible as
a result of the occurrence of an event specified in clause (i) of this Section. Whenever the Notes
shall become convertible pursuant to this Section 14.01, the Company or, at the Company’s request,
the Trustee in the name and at the expense of the Company, shall notify the holders of the event
triggering such convertibility in the manner provided in Section 15.03, and the Company shall also
publicly announce such information and publish it on the Company’s web site. Any notice so given
shall be conclusively presumed to have been duly given, whether or not the holder receives such
notice.

     The Trustee (or other Conversion Agent appointed by the Company) shall have no obligation to
determine the Trading Price under clause (ii) of this Section 14.01 unless the Company has
requested such a determination; and the Company shall have no obligation to make such request
unless a holder provides it with reasonable evidence that the Trading Price per $1,000 principal
amount of Notes would be less than 98% of the product of the Closing Sale Price and the Conversion
Rate. If such evidence is provided, the Company shall request that the Trustee (or other
Conversion Agent) determine the Trading Price of the Notes beginning on the next Trading Day and on
each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Closing Sale Price and the Conversion Rate.

     (b) In addition, if:

     (i) (A) the Company distributes to all or substantially all holders of its Common Stock
rights or warrants entitling them (for a period expiring within 60 days of the declaration
date of such distribution) to subscribe for or purchase shares of Common Stock, at a price
per share less than the average of the Closing Sale Price for the ten (10) Trading Days
immediately preceding, but not including, the declaration date for such distribution, or

     (B) the Company distributes to all or substantially all holders of its Common Stock,
assets (including cash), debt securities or rights or warrants to purchase its securities,
where the Fair Market Value of such distribution per share of Common Stock

60

 

      exceeds 5% of the Closing Sale Price on the Trading Day immediately preceding the date
for such distribution,

then, in either case, the Notes may be surrendered for conversion at any time on and after
the date that the Company gives notice to the holders of such distribution, which shall be
not less than 20 days prior to the Ex-Dividend Time for such distribution, until the earlier
of the close of business on the Business Day immediately preceding, but not including, the
Ex-Dividend Time or the date the Company publicly announces that such distribution will not
take place; provided that no adjustment to the Conversion Rate or the ability of a holder of
a Note to convert will be made if the holder will otherwise participate in such distribution
without conversion;

     (ii) if any of the events described in clause (2), (3) or (4) of the definition of
Fundamental Change occurs, holders may surrender any Notes for conversion during the period
starting on the 15th day prior to the anticipated Effective Date of the applicable
Fundamental Change and ending at the close of business on the 15th day after the actual
Effective Date of such Fundamental Change transaction or, if such transaction results in
holders having a right to require the Company to repurchase the Notes, the second business
day preceding the Fundamental Change Repurchase Date (as specified in the Fundamental Change
Repurchase Right Notice). In connection with such a Fundamental Change and in accordance
with Section 3.05 hereof, the Company will send holders a Fundamental Change Conversion
Right Notice at least 15 Trading Days prior to the anticipated Effective Date of the
Fundamental Change in which the Company will notify holders that, among other things, they
will have the right to convert the Notes. Upon such a conversion in connection with the
events described in clause (2), (3) or (4) of the definition of Fundamental Change, holders
will receive any increase in the conversion rate pursuant to Section 14.06 hereof if such
conversion occurs within the time frames specified therein (subject to the right of the
Company set forth in Section 14.06 hereof). Notwithstanding the foregoing, if the Effective
Date of the Fundamental Change identified in the Fundamental Change Conversion Right Notice
does not occur within 20 days of the anticipated Effective Date specified in such notice,
then the right of holders to convert the Notes will terminate and, to the extent such
Fundamental Change is expected to occur at a later date, the Company again shall comply with
the requirements of this Section 14.01(b)(ii) at such later date in connection with such
Fundamental Change. If a Fundamental Change occurs, holders may also have the right, at the
option of the holders, to require the Company to repurchase all or a portion of the Notes in
accordance with Section 3.05 hereof; or

     (iii) in case any holder of Notes exercises its right to require the Company to
repurchase such Notes in accordance with Section 3.05 hereof, the conversion right in
respect of the Note, or portion thereof so submitted, shall expire at the close of business
on the last Business Day immediately preceding the Fundamental Change Repurchase Date or
such earlier date as the Notes are presented for purchase, unless the Company defaults in
making the payment due upon repurchase, in which case such conversion right shall expire at
the close of business on the date the default is cured and the Notes are purchased by the
Company (in each case subject to any rules and procedures of the expository with respect to
any Global Note).

61

 

          “Ex-Dividend Time” means, with respect to any distribution on shares of Common Stock, the
first date on which the Common Stock trades, regular way, on the principal securities market on
which the Common Stock are then traded without the right to receive such distribution.

          (c) A Note in respect of which a holder is electing to exercise its option to require
repurchase upon a Fundamental Change pursuant to Section 3.05 or repurchase pursuant to Section
3.06 may be converted only if such holder withdraws its election in accordance with Section 3.05 or
Section 3.08, respectively. A holder of Notes is not entitled to any rights of a holder of Common
Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes
are deemed to have been converted to Common Stock under this Article 14.

          Section 14.02. Conversion Procedures. To convert a Note, a holder must (a) complete and
manually sign the Conversion Notice or a facsimile of the Conversion Notice (a “Conversion Notice”)
in the form set forth on the reverse of the Note and deliver such notice to the Conversion Agent,
(b) surrender the Note to the Conversion Agent, (c) furnish appropriate endorsements and transfer
documents if required by the Registrar or the Conversion Agent, (d) pay any transfer or similar
tax, if required and (e) if required, pay funds equal to the interest payable on the next interest
payment date. The date, within the time periods set forth in Section 14.01, on which the holder
satisfies all of those requirements is the “Conversion Date”. Except as provided in Section
14.06(g), the Company shall deliver to the holder through the Conversion Agent, no later than the
third Business Day following the Conversion Date, a certificate for the number of whole shares of
Common Stock issuable upon the conversion and, if applicable, cash in lieu of any fractional shares
pursuant to Section 14.04.

          In the case of a Global Note, the Conversion Notices may be delivered and such Notes may be
surrendered for conversion in accordance with the applicable procedures of the Depositary as in
effect from time to time. In order to cause a Depositary participant to complete a Conversion
Notice, a beneficial holder must complete, or cause to be completed, the appropriate instruction
form for conversion pursuant to the Depositary’s book-entry conversion program. The Person in
whose name the Common Stock certificate is registered shall be deemed to be a shareholder of record
at the close of business on the applicable Conversion Date; provided, however, that if any such
date is a date when the stock transfer books of the Company are closed, such Person shall be deemed
a shareholder of record as of the next date on which the stock transfer books of the Company are
open.

          No payment or adjustment shall be made for dividends on, or other distributions with respect
to, any Common Stock except as provided in this Article 14. On conversion of a Note, except for
conversion during the period from the close of business on any record date immediately preceding
any interest payment date to the close of business on the Business Day immediately preceding such
interest payment date, in which case the holder on such record date shall receive the interest
payable on such interest payment date, that portion of accrued and unpaid interest on the converted
Note attributable to the period from the most recent interest payment date (or, if no interest
payment date has occurred, from the date of original issuance of the Notes) through the Conversion
Date shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the holder thereof through delivery of the Common

62

 

          Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for
the Note being converted pursuant to the provisions hereof, and the Fair Market Value of such
shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be
treated as issued, to the extent thereof, first in exchange for accrued and unpaid interest accrued
through the Conversion Date and the balance, if any, of such Fair Market Value of such Common Stock
(and any such cash payment) shall be treated as issued in exchange for the principal amount of the
Note being converted pursuant to the provisions hereof.

          If a holder converts more than one Note at the same time, the number of shares of Common Stock
issuable upon the conversion shall be based on the aggregate principal amount of Notes converted.

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

          Notes or portions thereof surrendered for conversion during the period from the close of
business on any record date immediately preceding any interest payment date to the close of
business on the Business Day immediately preceding such interest payment date shall be accompanied
by payment to the Company or its order, in immediately available funds or other funds acceptable to
the Company, of an amount equal to the interest payable on such interest payment date with respect
to the principal amount of Notes or portions thereof being surrendered for conversion; provided
that no such payment need be made if (1) the Company has specified a redemption date that occurs
during the period from the close of business on a record date to the close of business on the
Business Day immediately preceding the interest payment date to which such record date relates, (2)
the Company has specified a Fundamental Change Repurchase Date during such period or (3) any
overdue interest exists on the Conversion Date with respect to the Notes converted, but only to the
extent of overdue interest.

          Section 14.03. Payment upon Conversion. (a) In the event that the Company receives notice of
conversion on or prior to the Optional Redemption Notice Date or the day that is twenty (20) days
prior to the Maturity of the Notes (the “Final Notice Date”), the following procedures will apply:

     If the Company chooses to satisfy all or any portion of the Company’s obligation (the
“Conversion Obligation”) in cash, the Company will notify the holder through the Trustee of
the dollar amount to be satisfied in cash (which must be expressed either as 100% of the
Conversion Obligation or as a fixed dollar amount) at any time on or before the date that is
two Business Days following the conversion date (the “Cash Settlement Notice Period”). If
the Company timely elects to pay cash for any portion of the shares otherwise issuable to
such holder, the conversion notice may be retracted by the holder at any time during the two
Business Day period beginning on the day after the final day of the Cash Settlement Notice
Period (the “Conversion Retraction Period”); no such retraction can be made (and a
conversion notice shall be irrevocable) if the Company does not elect to deliver cash in
lieu of shares (other than cash in lieu of fractional shares). If the conversion notice has
not been retracted, then settlement (in cash and/or shares) will occur on the Business Day
following the final day of the twenty (20) Trading

63

 

Day period beginning on the day after the final day of the Conversion Retraction Period
(the “Cash Settlement Averaging Period”). Settlement amounts will be computed as follows:

     (i)
If the Company elects to satisfy the entire Conversion Obligation in shares, the Company will deliver to holders surrendering Notes for conversion a
number of shares equal to (1) the aggregate original principal amount of Notes to be
converted divided by 1,000 multiplied by (2) the applicable Conversion Rate.

     (ii) If the Company elects to satisfy the entire Conversion Obligation in cash,
the Company will deliver to holders surrendering Notes for conversion cash in an
amount equal to the product of:

     (A) a number equal to (1) the aggregate original principal amount of
Notes to be converted divided by 1,000 multiplied by (2) the Conversion Rate
and

     (B) the average of the Closing Sale Price of the Common Stock during
the Cash Settlement Averaging Period.

     (iii) If the Company elects to satisfy in cash a fixed portion of the
Conversion Obligation other than the entire obligation, the Company will deliver to
holders surrendering Notes for conversion such cash amount (“Cash Amount”) and a
number of shares equal to the excess, if any, of the number of shares equal to (i)
the aggregate original principal amount of Notes to be converted divided by 1,000,
multiplied by (ii) the Conversion Rate, over the number of shares equal to the sum,
for each day of the Cash Settlement Averaging Period, of (x) the Cash Amount,
divided by the number of days in the Cash Settlement Averaging Period, divided by
(y) the Closing Sale Price of the Common Stock. In addition, the Company will pay
cash for all fractional shares of Common Stock based on the average Closing Sale
Price of the Common Stock during the Cash Settlement Averaging Period.

     (iv) If the Company elects to satisfy the Conversion Obligation as described in
subparagraphs (i) and (iii) above, and on the date the notice of conversion is
submitted by the holder, such holder’s Notes (x) have not been registered under the
Securities Act or are not freely transferable pursuant to Rule 144(k) under the
Securities Act and (y) the Company has not complied with the registration
obligations provided in the Registration Rights Agreement, then the Company shall
deliver to holders of such Notes an additional number of shares equal to 3% of the
number of shares calculated under subparagraphs (i) and (iii) above.

          (b) In the event that the Company receives notice of conversion after an Optional Redemption
Notice Date or the Final Notice Date, the Company will not send individual notices of its election
to satisfy all or any portion of the Conversion Obligation in

64

 

cash. Instead, if the Company chooses to redeem all or a portion of the Notes, the Company’s
notice of redemption will inform the holders of its election to deliver shares of Common Stock or
cash with respect to Notes converted prior to the redemption date. In addition, if the Company
chooses to satisfy all or any portion of the Conversion Obligation with respect to conversions
after the Final Notice Date in cash, the Company will send a single notice to the holders through
the Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of
the Conversion Obligation or as a fixed dollar amount) at any time on or before the Final Notice
Date. Settlement amounts will be computed and settlement dates will be determined in the same
manner as set forth under Section 14.03(a) above except that the “Cash Settlement Averaging Period”
shall be the twenty (20) consecutive Trading Day period beginning on the Trading Day after the
conversion date. If a conversion notice is received after an Optional Redemption Notice Date or
the Final Notice Date, the holder of Notes subject to such conversion notice will not be allowed to
retract the conversion notice. Settlement (in cash and/or shares) will occur on the Business Day
following the final day of such Cash Settlement Averaging Period. If the Company does not elect to
satisfy any part of the Conversion Obligation in cash (other than cash in lieu of any fractional
shares), delivery of shares of Common Stock into which the Note are converted (and cash in lieu of
any fractional shares) will be made through the Conversion Agent or the Depositary, as the case may
be, as soon as practicable on or after the conversion date.

          (c) Notwithstanding anything to the contrary in this Indenture, at any time prior to Maturity,
the Company may irrevocably elect, in its sole discretion without the consent of the holders of the
Notes, by notice to the Trustee and the holders of the Notes to satisfy in cash 100% of the
principal amount of the Notes converted after the date of such election. After making such an
election, the Company still may satisfy the remainder of the Conversion Obligation to the extent it
exceeds the principal amount in cash or Common Stock or a combination of cash and Common Stock. If
the Company chooses to satisfy all or a portion of the remainder of the Conversion Obligation in
cash, the Company will provide notice of such election in the same manner as set forth above under
either clause (a) or (b), whichever is applicable. If the Company chooses to satisfy all of the
remainder of the Conversion Obligation in Common Stock, notice of the election to deliver cash for
the principal amount will be deemed to have been provided on the last date of the Cash Settlement
Notice Period and the notice of conversion will not be retractable. Settlement amounts will be
computed and settlement dates will be determined in the same manner as set forth above under clause
(a) or (b), as applicable.

          Section 14.04. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common
Stock or scrip certificates representing fractional shares shall be issued upon conversion of
Notes. If more than one Note shall be surrendered for conversion at one time by the same holder,
the number of full shares that shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of
any Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current
market price thereof to the holder of Notes. For purposes of this Section 14.04, the “current
market price” of a share of Common Stock shall be the Closing Sale Price on the last Business Day
immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have
been converted.

65

 

          Section 14.05. Conversion Rate. Each $1,000 principal amount of the Notes shall be convertible
into the number of shares of Common Stock specified in the form of Note (herein called the
“Conversion Rate”) attached as Exhibit A hereto, subject to adjustment as provided in this Article
14.

          Section 14.06. Adjustment of Conversion Rate. (a) The Conversion Rate shall be subject to
adjustment, without duplication, from time to time upon the occurrence of any of the following:

     (1) Stock Dividends in Common Stock. In case the Company shall pay or make a
dividend or other distribution on shares of Common Stock payable exclusively in shares of
Common Stock, the Conversion Rate in effect at the opening of business on the day following
the date fixed for the determination of stockholders entitled to receive such dividend or
other distribution shall be increased by dividing such Conversion Rate by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding at the close
of business on the date fixed for such determination and the denominator shall be the sum of
such number of shares and the total number of shares constituting such dividend or other
distribution, such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If, after any such date fixed for
determination, any dividend or distribution is not in fact paid, the Conversion Rate shall
be immediately readjusted, effective as of the date the Company’s Board of Directors
determines not to pay such dividend or distribution, to the Conversion Rate that would have
been in effect if such determination date had not been fixed. For the purposes of this
clause (1), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will
not pay any dividend or make any distribution on shares of Common Stock held in the treasury
of the Company.

     (2) Issuance of Rights or Warrants. In case the Company shall issue rights or
warrants to all or substantially all holders of its Common Stock entitling them for a period
expiring within 60 days from the date of issuance of the rights or warrants to subscribe for
or purchase shares of Common Stock at a price per share less than the Current Market Price
per share of Common Stock on the date fixed for the determination of stockholders entitled
to receive such rights or warrants (other than any rights, options or warrants that (x) by
their terms will also be issued to any holder upon conversion of a Note into shares of
Common Stock without any action required by the Company or any other Person or (y) are
distributed to shareholders of the Company upon a merger or consolidation in compliance with
Section 11.01 hereof), then the Conversion Rate in effect at the opening of business on the
day following the date fixed for such determination shall be increased by dividing such
Conversion Rate by a fraction:

     (A) numerator of which shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination plus
the number of shares of Common Stock that the aggregate of the offering

66

 

price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at such Current Market Price; and

     (B) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination plus
the number of shares of Common Stock so offered for subscription or purchase,

such increase to become effective immediately after the opening of business on the day
following the date fixed for such determination. If, after any such date fixed for
determination, any such rights, options or warrants are not in fact issued, or are not
exercised prior to the expiration thereof, the Conversion Rate shall be immediately
readjusted, effective as of the date such rights, options or warrants expire, or the date
the Company’s Board of Directors determines not to issue such rights, options or warrants,
to the Conversion Rate that would have been in effect if the unexercised rights, options or
warrants had never been granted or such determination date had not been fixed, as the case
may be and as a result no additional shares are delivered or issued pursuant to such rights
or warrants. For the purposes of this clause (2), the number of shares of Common Stock at
any time outstanding shall not include shares held in the treasury of the Company but shall
include shares issuable in respect of scrip certificates issued in
lieu of fractions of shares of Common Stock. The Company will not issue any rights, options or warrants in
respect of shares of Common Stock held in the treasury of the Company.

          (3) Stock Splits and Combinations. (i) In case outstanding shares of Common
Stock shall be subdivided or split into a greater number of shares of Common Stock, then the
Conversion Rate in effect at the opening of business on the day following the day upon which
such subdivision or split becomes effective shall be proportionately increased; (ii) in case
outstanding shares of Common Stock shall be combined or reclassified into a smaller number
of shares of Common Stock, then the Conversion Rate in effect at the opening of business on
the day following the day upon which such combination or reclassification becomes effective
shall be proportionately reduced and (iii) in case the Company issues any shares of its
Capital Stock in a reclassification of the outstanding shares of Common Stock, then the
Conversion Rate in effect at the opening of business on the day following the day upon which
such reclassification becomes effective shall be proportionately
applied to the new class of shares of Capital Stock of the Company into which the Common Stock was reclassified; in each
case, such increase, reduction or reclassification, as the case may be, to become effective
immediately after the opening of business on the Business Day following the day upon which
such subdivision, combination or reclassification becomes effective.

          (4) Distribution of Indebtedness, Securities or Assets. In case the Company
shall, by dividend or otherwise, distribute to all or substantially all holders of its
Common Stock evidences of its indebtedness, securities, assets or certain rights to purchase
the Company’s securities (provided, that if these rights are only exercisable upon the
occurrence of specified triggering events, then the conversion rate will not be adjusted
until the triggering events occur), but excluding (i) any dividends or distributions
referred to in clause (1) or (5) of this Section 14.06(a), (ii) any rights or warrants
referred to in

67

 

           clause (2) of this Section 14.06(a), (iii) any dividends or distributions paid
exclusively in cash described in clause (6), (7) or (8) of this Section 14.06(a) (the
“Distributed Assets”), then the Conversion Rate shall be adjusted so that the same shall
equal the rate determined by multiplying the Conversion Rate in effect immediately prior to
the close of business on the record date fixed for the determination of stockholders
entitled to receive such distribution by a fraction:

     (A) the numerator of which shall be the Current Market Price per share of the
Company’s Common Stock on the record date; and

     (B) the denominator of which shall be the such Current Market Price per share
of Common Stock less the Fair Market Value, as determined by the Company’s Board of
Directors, whose determination in good faith shall be conclusive and described in a
Board Resolution filed with the Trustee, of the portion of those Distributed Assets
applicable to one share of Common Stock, such adjustment to become effective
immediately after the record date fixed for the determination of stockholders
entitled to receive such distribution.

If after any such date fixed for determination, any such distribution is not in fact made,
the Conversion Rate shall be immediately readjusted, effective as of the date the Company’s
Board of Directors determines not to make such distribution, to the Conversion Rate that
would have been in effect if such determination date had not been fixed.

          Notwithstanding the foregoing, in cases where (i) the Fair Market Value per share of
the Distributed Assets equals or exceeds the Current Market Price of the Company’s Common
Stock, or (ii) the Current Market Price of the Company’s Common Stock exceeds the Fair
Market Value per share of the Distributed Assets by less than $1.00, in lieu of the
adjustment set forth in this Section 14.06(a)(4), holders will have the right to receive
upon conversion, in addition to shares of Common Stock, if any, the amount and type of
Distributed Assets such holders would have received upon conversion of such holders’ Notes
if they had been converted immediately prior to the record date.

          (5) Spin-Offs. In case the Company shall distribute to all or substantially
all holders of its Common Stock shares of Capital Stock of any class or series, or similar
Equity Interests, of or relating to a Subsidiary or other business unit (a “Spin-off”), then
the Conversion Rate shall be adjusted so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the close of business on the
record date fixed for the determination of stockholders entitled to receive such
distribution by an adjustment factor equal to the sum of the Daily Adjustments for each of
the 10 consecutive Trading Days beginning on the effective date of the Spin-off, such
adjustment to become effective on the 10th Trading Day from, and including, the effective
date of the Spin-off.

          (6) Cash Distributions. In case the Company shall, by dividend or otherwise,
distribute to all or substantially all holders of outstanding shares of its Common Stock
distributions consisting exclusively of cash, then the Conversion Rate shall be adjusted so

68

 

that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the close of business on the date fixed for determination of the
stockholders entitled to receive such distribution by a fraction:

     (A) the numerator of which shall be equal to the Current Market Price per share
of Common Stock on the date fixed for such determination; and

     (B) the denominator of which shall be equal to the Current Market Price per
share of Common Stock on such date fixed for determination less the amount per share
of such distribution,

such adjustment to become effective immediately after the record date fixed for the
determination of stockholders entitled to receive such distribution.

Notwithstanding the foregoing, in cases where (i) the per share amount of such distribution
equals or exceeds the Current Market Price of the Company’s Common Stock, or (ii) the
Current Market Price of the Company’s Common Stock exceeds the per share amount of such
distribution by less than $1.00, in lieu of the adjustment set forth in this Section
14.06(a)(6), holders will have the right to receive upon conversion, in addition to shares
of Common Stock, if any, such distribution such holders would have received upon conversion
of such holders’ Notes if they had been converted immediately prior to the record date.

          (7) Tender or Exchange Offers. In case the Company or any Subsidiary of the
Company shall make a payment in respect of a tender offer or exchange offer for any portion
of the Company’s Common Stock, in which event, to the extent the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Closing 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 offer or exchange offer (the “Expiration
Date”), as the case may be, then the Conversion Rate shall be adjusted so that the same
shall equal the rate determined by multiplying the Conversion Rate immediately prior to
close of business on the Expiration Date by a fraction:

     (A) the numerator of which shall be equal to the sum of (a) the Fair Market
Value, as determined by the Board of Directors of the Company, of the aggregate
consideration payable for all shares of Common Stock purchased by the Company in the
tender or exchange offer and (b) the product of (i) the number of shares of Common
Stock outstanding less any such purchased shares and (ii) the Closing Sale Price of
the Common Stock on the Trading Day next succeeding the Expiration Date; and

     (B)
the denominator of which shall be equal to the product of (a) the number of shares of Common Stock outstanding, including any such purchased shares and (b) the
Closing Sale Price of the Common Stock on the Trading Day next succeeding the
Expiration Date, such adjustment to become effective

69

 

          immediately after the opening of business on the second Trading Day next
succeeding the Expiration Date.

          (8) Repurchases. In case the Company or any of its Subsidiaries shall make a
payment in respect of a repurchase of Common Stock the consideration for which exceeds the
average of the Closing Sale Prices of the Common Stock for the five consecutive Trading Days
ending on the relevant repurchase date (such amount, the “Repurchase Premium”), and that
repurchase, together with any other repurchases of Common Stock by the Company or any of its
Subsidiaries involving a Repurchase Premium concluded within the preceding 12 months,
results in the payment by the Company of an aggregate consideration exceeding an amount
equal to 10% of the Market Capitalization of the Company’s Common Stock, then the Conversion
Rate shall be adjusted so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect at the time of such repurchase triggering the adjustment by a
fraction:

     (A) the numerator of which shall be equal to the Current Market Price of the
Common Stock; and

     (B) the denominator of which shall be equal to (a) the Current Market Price of
the Common Stock minus (b) the quotient of (i) the aggregate amount of all the
Repurchase Premiums paid in connection with such repurchases and (ii) the number of
            shares of Common Stock outstanding on the day next succeeding the date of the
repurchase triggering the adjustment, as determined by the Board of Directors of the
Company;

provided, that no adjustment to the Conversion Rate shall be made to the extent the
Conversion Rate is not increased as a result of the above calculation; and provided further
that the repurchases of Common Stock effected by the Company or its agent in conformity with
Rule 10b-18 under the Exchange Act will not be included in any adjustment to the Conversion
Rate made pursuant to this Section 14.06(a)(8).

For purposes of this Section 14.06(a)(8):

     (A) the market capitalization shall be calculated by multiplying the Current
Market Price by the number of shares of Common Stock then outstanding on the date of
the repurchase triggering the adjustment immediately prior to such repurchase, and

     (B) in determining the repurchase premium, the “then-prevailing market price”
of the Company’s Common Stock will be the average of the Closing Sale Prices of the
Company’s Common Stock for the five consecutive Trading Days ending on the relevant
repurchase date.

If a payment by the Company shall cause an adjustment to the Conversion Rate under both
clause (7) and clause (8) of this Section 14.06(a), the provisions of Section 14.06(a)(7)
shall control.

70

 

          (9) Third Party Tender or Exchange Offers. In case a Person other than the
Company or its Subsidiaries makes a payment in respect of a tender offer or exchange offer
(a “Third Party Offeror”) for any portion of the Company’s Common Stock in which, as of the
Expiration Date, the Board of Directors does not recommend rejection of such offer, and only
if (i) the number of shares acquired by the Third Party Offeror pursuant to such tender
offer or exchange offer increases such Third Party Offeror’s ownership of Common Stock to
more than twenty-five percent (25%) of the total shares of Common Stock outstanding and (ii)
the cash and value of any other consideration included in the payment per share of Common
Stock exceeds the Current Market Price, the Conversion Rate shall be adjusted by multiplying
the Conversion Rate by a fraction:

     (A) the numerator of which shall be the sum of (a) the Fair Market Value of the
aggregate consideration payable for all shares of the Common Stock purchased in the
tender or exchange offer and (b) the product of (i) the number of shares of Common
Stock outstanding less any such purchased shares of Common Stock and (ii) the
Current Market Price (as the term is used in clause (d) of the definition thereof);
and

     (B) the denominator of which shall be the product of (a) the number of shares
of Common Stock outstanding, including any such purchased shares of Common Stock and
(b) the Current Market Price (as the term is used in clause (d) of the definition
thereof).

Notwithstanding the foregoing, the adjustment referred to in this Section 14.06(a)(9) shall
not be made if as of the closing date of such tender offer or exchange offer, the offering
documents relating to such tender offer or exchange offer disclose a plan or an intention to
cause the Company to engage in a consolidation, merger or a sale of all or substantially all
of the Company’s assets.

          (b) No Adjustment. No adjustment in the Conversion Rate shall be made:

          (1) 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;

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

          (3) upon the issuance of any shares of Common Stock pursuant to any option, warrant,
right or exercisable, exchangeable or convertible security not described in clause (2) of
this Section 14.06(b) and outstanding as of the date the Notes were first issued;

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

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

71

 

In addition, notwithstanding anything to the contrary contained in Section 14.06(a), the Company
will not be required to make any adjustment to the Conversion Rate or to the right of holders of
Notes to convert the Notes as a result of any transaction that otherwise would require adjustment
pursuant to clause (a) of this Section 14.06 if the holders of the Notes (including holders of
beneficial interests therein) actually participate in such transaction on an equal and ratable
basis.

          (c) Increase in Conversion Rate due to Taxes. The Company may make such increases in
the Conversion Rate, for the remaining term of the Notes or any shorter term, in addition to those
required by clause (a) of this Section 14.06, as the Board of Directors of the Company considers to
be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock
or rights to purchase Common Stock resulting from any dividend or distribution of stock or issuance
of rights or warrants to purchase or subscribe for stock or from any event treated as such for
income tax purposes.

          (d) Temporary Increase in Conversion Rate. To the extent permitted by applicable law,
the Company from time to time may increase the Conversion Rate by any amount for any period of time
if the period is at least twenty (20) days, the increase is irrevocable during such period, and the
Company’s Board of Directors shall have made a determination that such increase would be in the
best interests of the Company, which determination shall be conclusive; provided, however, that no
such increase shall be taken into account for purposes of determining whether the closing price of
the Common Stock equals or exceeds 105% of the Conversion Price in connection with an event which
would otherwise be a Fundamental Change. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall give notice of the increase to the holders in the manner
provided in Section 13.02, with a copy to the Trustee and Conversion Agent, at least fifteen (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.

          (e) Fundamental Change Make-Whole Adjustment. In case of a Fundamental Change as
described in clause (b), (c) or (d) in the definition thereof (and subject to the Company’s rights
under this Section 14.06), solely upon receipt by the Conversion Agent of any holder’s Conversion
Notice on or subsequent to the Effective Date of such Fundamental Change and prior to the 45th day
following such Effective Date (or, if earlier and to the extent applicable, the close of business
on the second Business Day immediately preceding the Fundamental Change Repurchase Date (as
specified in the Fundamental Change Repurchase Right Notice)), the Company shall increase the
Conversion Rate for the Notes surrendered for conversion by such holder by the number of Additional
Shares determined in accordance with this Section 14.06(e); provided, however that no increase
shall be made in the case of a Fundamental Change if at least 90% of the consideration paid for the
Company’s Common Stock (excluding cash payments for fractional shares and cash payments made
pursuant to dissenters’ appraisal rights) in such Fundamental Change transaction consists of shares
of Capital Stock traded on New York Stock Exchange or another U.S. national securities exchange or
quoted on Nasdaq Stock Market or another established automated over-the-counter trading market in
the United States (or that will be so traded or quoted immediately following the transaction) and
as a result of such transaction or transactions the Notes become convertible solely into such
Capital Stock.

72

 

          The number of Additional Shares will be determined by reference to the table below, based on
the Effective Date of the Fundamental Change and the Stock Price paid per share of Common Stock in
such Fundamental Change transaction, expressed as a number of Additional Shares issuable per $1,000
initial principal amount of Notes as a result of a Fundamental Change that occurs in the
corresponding period:

The Stock Prices set forth in the first row of the table above shall be adjusted as of any
date on which the Conversion Rate of the Notes is adjusted in accordance with Section 14.06 hereof.
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 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 shall be adjusted in the same
manner and for the same events as the Conversion Rate as set forth in Section 14.06 hereof.

          The exact Stock Price and Conversion Dates may not be set forth on the table; in which case,
if the Stock Price is:

     (A) between two Stock Price amounts on the table or the Conversion Date is between two
dates on the table, the number of Additional Shares will be determined by straight-line
interpolation between the number of Additional Shares set forth for the higher and lower
stock price amounts and the two dates, as applicable, based on a 365-day year;

     (B) more than $250.00 per share (subject to adjustment), no Additional Shares will be
issued upon conversion; and

     (C) less than $77.05 per share (subject to adjustment), no Additional Shares will be
issued upon conversion.

          Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock
issuable upon conversion of a Note exceed 12.9835 per $1,000 initial principal amount of the Notes,
after giving effect to the make whole adjustment and any related increase in the Conversion Rate
pursuant to this Section 14.06(e), subject to anti-dilution adjustments set forth in Section
14.06(a) hereof.

          (f) Public Acquirer Change of Control. Notwithstanding anything in this Section
14.06, in the case of a Public Acquirer Change of Control, the Company may, in lieu of permitting a
repurchase at the holder’s option as set forth in Section 3.05 hereof or adjusting the Conversion
Rate as provided in Section 14.06(e) hereof, elect to adjust the Conversion Rate such that from and
after the Effective Date of such Public Acquirer Change of Control, holders of the

73

 

Notes will be entitled to convert their Notes into a number of shares of Public Acquirer
Common Stock by adjusting the Conversion Rate in effect immediately before the Public Acquirer
Change of Control by a fraction:

     (A) the numerator of which will be (a) in the case of a share exchange, consolidation,
merger or binding share exchange, pursuant to which the Company’s Common Stock is converted
into cash, securities or other property, the Fair Market Value of all cash and any other
consideration (as determined by the Board of Directors of the Company) paid or payable per
share of the Company’s Common Stock or (b) in the case of any other Public Acquirer Change
of Control, the average of the last reported sale price of the Company’s Common Stock for
the five consecutive Trading Days prior to but excluding the Effective Date of such Public
Acquirer Change of Control, and

     (B) the denominator of which will be the average of the last reported sale prices of
the Public Acquirer Common Stock for the five consecutive Trading Days prior to but
excluding the Effective Date of such Public Acquirer Change of Control.

          If the Company elects to adjust the Conversion Rate and conversion obligation as described in
this Section 14.06(f), the Company shall send a Fundamental Change Conversion Right Notice to the
holders of Notes at least 15 Trading Days prior to the expected Effective Date of the Fundamental
Change that is also a Public Acquirer Change of Control, in accordance with Section 3.05 hereof.
If the Company elects to adjust the Conversion Rate in connection with a Public Acquirer Change of
Control, holders of the Notes shall not have the right to receive Additional Shares pursuant to
Section 14.06(e) or to require the Company to repurchase such Notes in connection with the
Fundamental Change that is also a Public Acquirer Change of Control.

          (g) Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate is
adjusted pursuant to this Section 14.06:

     (1) The Company shall compute the adjusted Conversion Rate in accordance with this
Section 14.06 and shall prepare an Officer’s Certificate setting forth (A) the adjusted
Conversion Rate, (B) the clause of this Section 14.06 pursuant to which such adjustment has
been made, showing in reasonable detail the facts upon which such adjustment is based, (C)
the calculation of such adjustment and (D) the date as of which such adjustment is
effective, and such certificate shall promptly be filed with the Trustee and with each
Conversion Agent; and

     (2) upon each such adjustment, a notice stating that the Conversion Rate has been
adjusted and setting forth the adjusted Conversion Rate shall be required, and as soon as
practicable after it is required, such notice shall be provided by the Company to all
holders in accordance with Section 14.11. Moreover, upon any determination by the Company,
the Conversion Agent or the Trustee that holders of the Notes are or will be entitled to
convert the Notes in accordance with this Section 14.06, the Company will issue a press
release and publish the information on its website.

74

 

          Unless and until a Responsible Officer of the Trustee shall have received an Officer’s
Certificate in accordance with this Section 14.06(g), the Trustee shall not be deemed to have
knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of
which it has knowledge is still in effect.

          Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with
respect to any such certificate or the information and calculations contained therein, except to
exhibit the same to any holder of Notes desiring inspection thereof at its office during normal
business hours.

          Section 14.07. Effect of Reclassification, Consolidation, Merger or Sale. Except as set forth
in Section 14.06(f), if any of the following events occur, namely (i) any reclassification or
change of the outstanding shares of the Company’s Common Stock, (ii) any consolidation, merger or
combination of the Company with another Person as a result of which holders of the Company’s Common
Stock shall be entitled to receive stock, other securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, (iii) the Company is a party to a
binding share exchange, or (iv) any sale or conveyance of all or substantially all of the
properties and assets of the Company to any other Person as a result of which holders of the
Company’s Common Stock shall be entitled to receive stock, other securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock, then the Company or
the successor or purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture providing that each Note shall be convertible into the type and amount of
shares of stock, other securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, binding share exchange, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes
(assuming, for such purposes, a sufficient number of authorized shares of Common Stock are
available to convert all such Notes) immediately prior to such reclassification, change,
consolidation, merger, combination, binding share exchange, sale or conveyance assuming such holder
of Common Stock did not exercise his rights of election, if any, as to the type or amount of stock,
other securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, binding share exchange, sale or
conveyance (provided that, if the type or amount of stock, other securities or other property or
assets (including cash) receivable upon such reclassification, change, consolidation, merger,
combination, binding share exchange, sale or conveyance is more than a single type of consideration
(determined based in part upon any form of stockholder election), then the type and amount of
consideration will be deemed to be the weighted average of the kind and amounts of consideration
received by the holders of the Company’s Common Stock that affirmatively makes such an election).
Such supplemental indenture shall provide for adjustments, which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Article 14.

          The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each holder of Notes, at its address appearing on the Note register provided for in Section 2.05 of
this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of such supplemental indenture.

75

 

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

          Interest will not accrue on any cash into which the Notes are convertible.

          Section 14.08. Taxes on Shares Issued. The issue of stock certificates on conversions of Notes
shall be made without charge to the converting Noteholder for any documentary, stamp or similar
issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required
to pay any such tax which may be payable in respect of any transfer involved in the issue and
delivery of stock in any name other than that of the holder of any Note converted, and the Company
shall not be required to issue or deliver any such stock certificate unless and until the Person or
Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

          Section 14.09. Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock
to provide for the conversion of the Notes from time to time as such Notes are presented for
conversion.

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

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

          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 in good faith and as expeditiously as possible, to the extent then permitted by the
rules and interpretations of the Commission (or any successor thereto), endeavor to secure such
registration or approval, as the case may be.

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

76

 

list such Common Stock issuable upon conversion of the Notes in accordance with the
requirements of such exchange or automated quotation system at such time.

          Section 14.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not
at any time be under any duty or responsibility to any holder of Notes to determine the Conversion
Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with
respect to the nature or extent or calculation of any such adjustment when made, or with respect to
the method employed, or herein or in any supplemental indenture provided to be employed, in making
the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or
property, which 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 14. 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 Noteholders 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 as
conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee
prior to the execution of any such supplemental indenture) with respect thereto.

          Section 14.11. Notice to holders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common
Stock that would require an adjustment in the Conversion Rate pursuant to Section 14.06; or

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

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

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

77

 

the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at
his address appearing on the Note register provided for in Section 2.05 of this Indenture, as
promptly as possible but in any event at least ten (10) days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding
up. Failure to give such notice, or any defect therein, shall not affect the legality or validity
of such dividend, distribution, authorization, grant, reclassification, reorganization,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

          Section 14.12. Rights Issued in Respect of Common Stock Issued upon Conversion. Each share of
Common Stock issued upon conversion of Notes pursuant to this Article 14 shall be entitled to
receive the appropriate number of common stock or preferred stock purchase rights, as the case may
be (the “Rights”), if any, that shares of Common Stock are entitled to receive 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 shareholder rights agreement adopted by the Company, as
the same may be amended from time to time (in each case, a “Rights Agreement”). Provided that such
Rights Agreement requires that each share of Common Stock issued upon conversion of Notes at any
time prior to the distribution of separate certificates representing the Rights be entitled to
receive such Rights, then, notwithstanding anything else to the contrary in this Article 14 there
shall not be any adjustment to the conversion privilege or Conversion Rate as a result of the
issuance of Rights, but an adjustment to the Conversion Rate shall be made with respect to Notes
then outstanding pursuant to Section 14.06 (to the extent required thereby) upon the separation of
the Rights from the Common Stock.

to the provisions of subsections (a)(1), (a)(2) and (a)(3) of Section 314 of the Trust Indenture
Act as now in effect or as hereafter amended or modified; provided further that this Section 15.07
shall not require this Indenture or the Trustee to be qualified under the Trust Indenture Act prior
to the time such qualification is in fact required under the terms of the Trust Indenture Act, nor
shall it constitute any admission or acknowledgment by any party to the Indenture that any such
qualification is required prior to the time such qualification is in fact required under the terms
of the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in an indenture qualified under the Trust
Indenture Act, such required provision shall control.

          Section 15.08. No Security Interest Created. Nothing in this Indenture or in the Notes,

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 7.09.

          Any corporation into which any authenticating agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or conversion

agent by giving written notice of termination to such authenticating agent and to the Company.

authenticating agent shall cease to be eligible under this Section, the Trustee shall either
promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor
authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of a successor
authenticating agent to all holders of Notes 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 such reasonable
compensation for its services as shall be agreed upon in writing between the Company and the
authenticating agent.

          The provisions of Sections 7.03, 7.04, 7.05, 8.03 and this Section 15.11 shall be applicable
to any authenticating agent.

          Section 15.12. Execution in Counterparts. This Indenture may be executed in any number of

the Indenture referred to on the reverse hereof), for value received hereby promises to pay to Cede

2025 at the office or agency of the Company maintained for that purpose in accordance with the
terms of the Indenture, in such coin or currency of the United States of America as at the time of

semiannually on February 15 and August 15 of each year, commencing February 15, 2006, on said
principal sum at said office or agency, in like coin or currency, at the rate per annum of 2.75%,
from the February 15 or August 15, as the case may be, next preceding the date of this Note to
which interest has been paid or duly provided for, unless the date hereof is a date to which
interest has been paid or duly provided for, in which case from the date of this Note, or unless no
interest has been paid or duly provided for on the Notes, in which case from August 15, 2005 until
payment of said principal sum has been made or duly provided for. Notwithstanding the foregoing,
if the date hereof is after any February 1 or August 1, as the case may be, and before the
following February 15 or August 15, this Note shall bear interest from such February 15 or August
15; provided that if the Company shall default in the payment of interest due on such February 15

excess of $2,000,000 shall, at the written election (timely made and containing appropriate wire
transfer information) of such holder, be paid by wire transfer of immediately available funds) or
(ii) by transfer to an account maintained by such Person located in the United States; provided
that payments to the Depositary will be made by wire transfer of immediately available funds to the

FORM OF REVERSE OF NOTE

NII HOLDINGS, INC.

2.75% CONVERTIBLE SENIOR NOTE DUE 2025

          This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.75%
Convertible Notes Due 2025 (herein called the “Notes”), initially limited in aggregate principal
amount to $350,000,000, issued and to be issued under and pursuant to an Indenture dated as of
August 15, 2005 (herein called the “Indenture”), between the Company and Wilmington Trust Company,
as trustee (herein called 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.

          In case an Event of Default shall have occurred and be continuing, the principal of, and
premium, if any, and accrued interest on, all Notes may be declared by either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Notes then outstanding, and upon
said declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

          The Indenture contains provisions permitting the Company and the Trustee, with the consent of
the holders of at least a majority in aggregate principal amount of the Notes at the time
outstanding, to execute supplemental indentures adding any provisions to or changing in any manner
or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying
in any manner the rights of the holders of the Notes; provided that no such supplemental indenture
shall (i) change the fixed Maturity of any Note, or reduce the rate or change the time of payment
of interest thereon, or reduce the principal amount thereof or premium, if any, thereon or reduce
any amount payable on redemption or repurchase thereof, or impair the right of any Noteholder to
institute suit for the payment thereof, or make the principal thereof or interest or premium, if
any, thereon payable in any coin or currency or payable at any place other than that provided in
the Indenture or the Notes, or change the obligation of the Company to redeem any Note on a
redemption date in a manner adverse to the holders of Notes, or change the obligation of the
Company to redeem any Note upon the happening of a Fundamental Change in a manner adverse to the
holders of Notes, or change the obligation of the Company to repurchase any Note on a Repurchase
Date in a manner adverse to the holders of Notes, or reduce the Conversion Rate otherwise than in
accordance with the terms of the Indenture or otherwise impair the right to convert the Notes into
Common Stock or cash subject to the terms set forth herein, including Section 14.07 thereof or
reduce the quorum or the voting requirements under the Indenture, or modify any of the provisions
of Section 10.02 or Section 6.07, except to increase any such percentage or to provide that certain
other provisions of the Indenture cannot be modified or waived without the consent of the holder of
each Note so affected, or change any obligation of the Company to maintain an office or agency in
the places and for the purposes set forth in Section 4.01 thereof, in each case, without the
consent of the holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes,
the holders of which are required to consent to any such supplemental indenture or to waive any
past Event of Default, without the consent of the holders of each Notes affected thereby. Subject
to the

 

 

provisions of the Indenture, 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 except a default in the
payment of interest, or any premium on or the principal of, any of the Notes, or a failure by the
Company to convert any Notes into Common Stock, cash or a combination of cash and Common Stock of
the Company, or a default in the payment of the redemption price, or a default in the payment of
the repurchase price on a Repurchase Date, or a default in respect of a covenant or provisions of
the Indenture which under Article 10 of the Indenture cannot be modified or amended without the
consent of the holders of each or all Notes then outstanding or affected thereby. Any such consent
or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners of this Note and any
Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

          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 of, and any premium and interest on, this Note at the place, at the respective times, at
the rate and in the coin or currency herein prescribed.

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

          The Notes are issuable in fully registered form, without coupons, in denominations of $1,000
principal amount and any multiple of $1,000. 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,
without payment of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration or
exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of any
other authorized denominations.

          At any time on or after August 20, 2010, the Notes may be redeemed at the option of the
Company, in whole or in part, upon mailing a notice of such redemption not less than 30 days but
not more than 60 days before the redemption date to the holders of Notes at their last registered
addresses, all as provided in the Indenture, for a redemption price in cash equal to 100% of the
principal amount of the notes to be redeemed, together with accrued and unpaid interest (including
additional amounts, if any) to, but excluding the date fixed for redemption; provided that if the
redemption date is on a February 15 or August 15, then the interest payable on such date shall be
paid to the holder of record on the preceding February 1 or August 1, respectively.

          The Company may not give notice of any redemption of the Notes if a default in the payment of
interest or premium, if any, on the Notes has occurred and is continuing.

          The Notes are not subject to redemption through the operation of any sinking fund.

 

 

          If a Fundamental Change occurs at any time prior to Maturity of the Notes, this Note will be
redeemable on a Fundamental Change Repurchase Date, no less than 20 and no more than 35 days after
notice thereof, at the option of the holder of this Note at a redemption price equal to 100% of the
principal amount thereof, together with accrued interest to (but excluding) the redemption date;
provided that if such Fundamental Change Repurchase Date is a February 15 or August 15, the
interest payable on such date shall be paid to the holder of record of this Note on the preceding
February 1 or August 1, respectively. The Notes will be redeemable in multiples of $1,000
principal amount. The Company shall mail to all holders of record of the Notes a notice of the
occurrence of a Fundamental Change and of the redemption right arising as a result thereof on or
before the 15th day after the occurrence of such Fundamental Change. For a Note to be so redeemed
at the option of the holder, the Company must receive at the office or agency of the Company
maintained for that purpose in accordance with the terms of the Indenture, such Note with the form
entitled “Option to Elect Repurchase Upon a Fundamental Change” on the reverse thereof duly
completed, together with such Note, duly endorsed for transfer, at any time prior to 5:00 p.m., New
York City time, on the second Business Day immediately preceding the Fundamental Change Repurchase
Date.

          Subject to the terms and conditions of the Indenture, the Company shall become obligated to
purchase, at the option of the holder, all or any portion of the Notes held by such holder on
August 15, 2010, August 15, 2012, August 15, 2015 and August 15, 2020 in whole multiples of $1,000
at a purchase price of 100% of the principal amount, plus any accrued and unpaid interest, on such
Note up to the Repurchase Date. As provided in Section 2.03 of the Indenture, if the Repurchase
Date is an interest payment date, the semi-annual payment of interest becoming due on such date
shall be payable to the holders of such Notes registered as such on the applicable record date. To
exercise such right, a holder shall deliver to the Company such Note with the form entitled
“Repurchase Notice” on the reverse thereof duly completed, together with the Note, duly endorsed
for transfer, at any time from the opening of business on the date that is 20 Business Days prior
to such Repurchase Date until the close of business on the Repurchase Date, and shall deliver the
Notes to the Trustee (or other paying agent appointed by the Company) as set forth in the
Indenture.

          Holders have the right to withdraw any Repurchase Notice by delivering to the Trustee (or
other paying agent appointed by the Company) a written notice of withdrawal up to the close of
business on the Repurchase Date, all as provided in the Indenture.

          If cash sufficient to pay the purchase price of all Notes or portions thereof to be purchased
as of the Repurchase Date is deposited with the Trustee (or other paying agent appointed by the
Company), on the Business Day following the Repurchase Date, interest will cease to accrue on such
Notes (or portions thereof) immediately after such Repurchase Date, and the holder thereof shall
have no other rights as such other than the right to receive the purchase price upon surrender of
such Note.

          Subject to the occurrence of certain events and in compliance with the provisions of the
Indenture, the holder hereof has the right to convert each $1,000 principal amount of the Notes
into 9.9835 shares of the Company’s Common Stock or a combination of shares of the Company’s Common
Stock and cash, subject to adjustment as provided in the Indenture. A Note in respect of which a
holder is exercising its right to require redemption upon a Fundamental

 

 

Change or repurchase on a Repurchase Date may be converted only if such holder withdraws its
election to exercise either such right in accordance with the terms of the Indenture. The
Conversion Rate for the Notes on any Conversion Date shall be determined as set forth in the
Indenture. The Company shall deliver cash or a check in lieu of any fractional share of Common
Stock.

          The Company shall deliver to the holder through the Conversion Agent, no later than the third
Business Day following the Conversion Date, a certificate for the number of whole shares of Common
Stock issuable upon the conversion and, if applicable, cash in lieu of any fractional shares.

          A holder may convert a portion of a Note if the principal amount of such portion is $1,000 or
an integral multiple of $1,000. No payment or adjustment shall be made for dividends on the Common
Stock except as provided in the Indenture. On conversion of a Note, except for conversion during
the period from the close of business on any record date immediately preceding any interest payment
date to the close of business on the Business Day immediately preceding such interest payment date,
in which case the holder on such record date shall receive the interest payable on such interest
payment date, that portion of accrued and unpaid interest on the converted Note attributable to the
period from the most recent interest payment date (or, if no interest payment date has occurred,
from the date of original issuance of the Notes) through the Conversion Date shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the holder
thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of
fractional shares), or cash in lieu thereof, in exchange for the Note being converted pursuant to
the provisions hereof.

          Notes or portions thereof surrendered for conversion during the period from the close of
business on any record date immediately preceding any interest payment date to the close of
business on the Business Day immediately preceding such interest payment date shall be accompanied
by payment to the Company or its order, in immediately available funds or other funds acceptable to
the Company, of an amount equal to the interest payable on such interest payment date with respect
to the principal amount of Notes or portions thereof being surrendered for conversion; provided
that no such payment need be made if (1) the Company has specified a Redemption Date that occurs
during the period from the close of business on a record date to the close of business on the
Business Day immediately preceding the interest payment date to which such record date relates, (2)
the Company has specified a Fundamental Change Repurchase Date during such period or (3) only to
the extent of overdue interest, any overdue interest exists on the Conversion Date with respect to
the Notes converted.

          No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid
in cash based upon the current market price of the Common Stock as provided in Section 14.04 of the
Indenture.

          To convert a Note, a holder must (a) complete and manually sign the conversion notice set
forth below or a facsimile thereof and deliver such notice to a Conversion Agent, (b) surrender the
Note to the Conversion Agent, (c) furnish appropriate endorsements and transfer documents
(including any certification that may be required under applicable law) if required by

 

 

the Conversion Agent, (d) pay any transfer or similar tax, if required and (e) if required pay
funds equal to the interest payable on the next interest payment date.

          The Conversion Rate will be adjusted as set forth in Article 14 of the Indenture.

          Any Notes called for redemption, unless surrendered for conversion by the holders thereof on
or before the close of business on the Business Day preceding the redemption date, may be deemed to
be redeemed from the holders of such Notes for an amount equal to the applicable redemption price,
together with accrued but unpaid interest to, but excluding, the date fixed for redemption, by one
or more investment banks or other purchasers who may agree with the Company (i) to purchase such
Notes from the holders thereof and convert them into shares of the Company’s Common Stock and (ii)
to make payment for such Notes as aforesaid to the Trustee in trust for the holders.

          Upon due presentment for registration of transfer of this Note at the office or agency of the
Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or
Notes of authorized denominations for an equal aggregate principal amount will be issued to the
transferee in exchange thereof, subject to the limitations provided in the Indenture, without
charge except for any tax, assessment or other governmental charge imposed in connection therewith.

          The Company, the Trustee, any authenticating agent, any paying agent, any Conversion Agent and
any Note registrar may deem and treat the registered holder hereof as the absolute owner of this
Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or
other writing hereon made by anyone other than the Company or any Note registrar) for the purpose
of receiving payment hereof, or on account hereof, for the conversion hereof and for all other
purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any paying
agent nor other Conversion Agent nor any Note registrar shall be affected by any notice to the
contrary. All payments made to or upon the order of such registered holder shall, to the extent of
the sum or sums paid, satisfy and discharge liability for monies payable on this Note.

          No recourse for the payment of the principal of, or any premium or interest on, this Note, or
for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture or any supplemental indenture or
in any Note, or 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, all such liability being, by
acceptance hereof and as part of the consideration for the issue hereof, expressly waived and
released.

          Terms used in this Note and defined in the Indenture are used herein as therein defined.

85 Broad Street

New York, New York 10004

Ladies and Gentlemen:

          NII Holdings, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to
Goldman, Sachs & Co. (the “Initial Purchaser”) $300,000,000 principal amount of its 2.75%
Convertible Notes due 2025 (the “Firm Securities”) to be issued pursuant to the provisions of an
Indenture to be dated as of August 15, 2005 (the “Indenture”) between the Company and Wilmington
Trust Company, as trustee (the “Trustee”). The Company also proposes to issue and sell to the
Initial Purchaser not more than an additional $50,000,000 principal amount of its 2.75% Convertible
Notes due 2025 (the “Additional Securities”) if and to the extent that the Initial Purchaser shall
have determined to exercise the right to purchase such Additional Securities granted to the Initial
Purchaser in Section 2 hereof. The Firm Securities and the Additional Securities are hereinafter
collectively referred to as the “Securities.” The Securities will be convertible into shares of
common stock, par value $0.001 per share, of the Company (the “Underlying Securities”) in
accordance with the terms of the Securities and the Indenture.

          The Securities will be offered without being registered under the Securities Act of 1933, as
amended (the “Securities Act”), to qualified institutional buyers in compliance with the exemption
from registration provided by Rule 144A under the Securities Act.

          The Initial Purchaser and its direct and indirect transferees will be entitled to the benefits
of a Registration Rights Agreement dated as of the Closing Date (as defined herein) between the
Company and the Initial Purchaser (the “Registration Rights Agreement”).

          In connection with the sale of the Securities, the Company has prepared a preliminary offering
memorandum (the “Preliminary Memorandum”) and will prepare a final offering memorandum (the “Final
Memorandum” and, with the Preliminary Memorandum, each a “Memorandum”) including or incorporating
by reference a description of the terms of the Securities and the Underlying Securities, the terms
of the offering and a description of the Company. As used herein, the term “Memorandum” shall
include in each case the documents incorporated by reference therein. The terms “supplement,”
“amendment” and “amend” as used herein with respect to a Memorandum shall include all documents
deemed to be incorporated by reference in the Preliminary Memorandum or Final Memorandum that are
filed subsequent to the date of such Memorandum with the Securities and Exchange Commission (the
“Commission”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

          1. Representations and Warranties. The Company represents and warrants to, and agrees
with, the Initial Purchaser that:

          (a) (i) Each document, if any, filed or to be filed pursuant to the Exchange Act and
incorporated by reference in either Memorandum complied or will comply when so filed in all
material respects with the Exchange Act and the applicable rules and regulations of the Commission
thereunder

1

 

and (ii) the Preliminary Memorandum does not contain and the Final Memorandum, in the
form used by the Initial Purchaser to confirm sales and on the Closing Date (as defined in Section
4), will not contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading, except that the representations and warranties set forth in this paragraph do
not apply to statements or omissions in either Memorandum based upon information relating to the
Initial Purchaser furnished to the Company in writing by the Initial Purchaser through you
expressly for use therein.

          (b) The Company has been duly incorporated, is validly existing as a corporation in good
standing under the laws of the jurisdiction of its incorporation, has the corporate power and
authority to own its property and to conduct its business as described in the Final Memorandum and
is duly qualified to transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such qualification, except
to the extent that the failure to be so qualified or be in good standing would not have a material
adverse effect on the Company and its subsidiaries listed on Schedule I (each, a “Subsidiary” and
collectively, the “Subsidiaries”), taken as a whole (a “Material Adverse Effect”).

          (c) Each of the Subsidiaries has been duly organized, is validly existing as a corporation or
limited liability company, as the case may be, in good standing under the laws of the jurisdiction
of its incorporation or organization (to the extent that such jurisdiction recognizes the legal
concept of good standing), has the power and authority to own its property and to conduct its
business as described in the Final Memorandum and is duly qualified to transact business and is in
good standing in each jurisdiction (to the extent that such jurisdiction recognizes the legal
concept of good standing) in which the conduct of its business or its ownership or leasing of
property requires such qualification, except to the extent that the failure to be so qualified or
be in good standing would not have a Material Adverse Effect. All of the issued shares of capital
stock, membership interests or equity interests, as the case may be, of each Subsidiary have been
duly and validly authorized and issued, are fully paid and non-assessable (to the extent that such
jurisdiction recognizes the legal concept of non-assessability) and except as set forth on Schedule
I are owned directly or indirectly by the Company, and, except as described in the Final
Memorandum, are free and clear of all liens, encumbrances, equities or claims. The Subsidiaries
listed on Schedule I are all of the subsidiaries of the Company other than inactive subsidiaries.

          (d) This Agreement has been duly authorized, executed and delivered by the Company.

          (e) The Company has an authorized capitalization as set forth in the Final Memorandum and all
of the issued and outstanding shares of capital stock of the Company have been duly authorized and

description thereof contained in the Final Memorandum under the caption “Description of Capital
Stock.”

          (f) The Securities have been duly authorized and, when executed and authenticated in
accordance with the provisions of the Indenture and delivered to and paid for by the Initial
Purchaser in accordance with the terms of this Agreement, will be valid and binding obligations of
the Company, enforceable in accordance with their terms, subject to the effects of applicable
bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors’ rights
generally and equitable principles of general applicability, and will be entitled to the benefits
of the Indenture and the Registration Rights Agreement.

2

 

          (g) The Underlying Securities issuable upon conversion of the Securities have been duly
authorized and reserved and, when issued upon conversion of the Securities in accordance with the
terms of the Securities, will be validly issued, fully paid and non-assessable, and the issuance of
the Underlying Securities will not be subject to any preemptive or similar rights.

          (h) Each of the Indenture and the Registration Rights Agreement has been duly authorized and,
when executed and delivered by the parties thereto as of the Closing Date, will be a valid and
binding agreement of the Company enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance or similar laws affecting creditors’ rights generally
and general principles of equity and except as rights to indemnification and contribution under the
Registration Rights Agreement may be limited under applicable law.

          (i) The execution and delivery by the Company of, and the performance by the Company of its
obligations under, this Agreement, the Indenture, the Registration Rights Agreement and the
Securities will not contravene any provision of (i) applicable law, (ii) the certificate of
incorporation or by-laws of the Company or (iii) any agreement or other instrument binding upon the
Company or any of the Subsidiaries, or any judgment, order or decree of any governmental body,
agency or court having jurisdiction over the Company or any Subsidiary, except, with respect to
clauses (i) and (iii), to the extent that any contravention would not have a Material Adverse
Effect. No consent, approval, authorization or order of, or qualification with, any governmental
body or agency is required for the performance by the Company of its obligations under this
Agreement, the Indenture, the Registration Rights Agreement or the Securities, except such as have
been obtained or may be required by the securities or Blue Sky laws of the various states in
connection with the offer and sale of the Securities and by federal and state securities laws with
respect to the Company’s obligations under the Registration Rights Agreement and as to which the
failure to so obtain would not have a material adverse effect on the ability of the Company to
perform its obligations under this Agreement, the Indenture, the Securities and the Registration
Rights Agreement.

          (j) The consolidated financial statements, together with the related schedules and notes,
incorporated by reference in the Memorandum present fairly the financial position of the Company
and its consolidated subsidiaries at the dates indicated and the consolidated statements of
operations, changes in stockholders’ equity and cash flows of the Company and its consolidated
subsidiaries for the periods specified (subject, in the case of unaudited financial statements, to
normal year-end adjustments); said financial statements have been prepared in conformity with
United States generally accepted accounting principles (“U.S. GAAP”) applied on a consistent basis
throughout the periods involved.

          (k) There has not occurred any material adverse change, or any development involving a
prospective material adverse change, in the condition, financial or otherwise, or in the earnings,
business or operations of the Company and its Subsidiaries, taken as a whole, from that set forth
in the Final Memorandum (exclusive of any amendments or supplements thereto subsequent to the date
of this Agreement).

          (l) There are no legal or governmental proceedings pending or, to the Company’s knowledge,
threatened to which the Company or any of its Subsidiaries is a party or to which any of the
properties of the Company or any of its Subsidiaries is subject, other than proceedings accurately
described in the Final Memorandum, that would have a material adverse effect on the power or
ability of the Company to perform its obligations under this Agreement, the Indenture, the
Registration Rights Agreement or the Securities or to consummate the transactions contemplated by
the Final Memorandum.

          (m) The Company and its Subsidiaries (i) are in compliance with any and all applicable
foreign, federal, state and local laws and regulations relating to the protection of human health
and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants

3

 

(“Environmental Laws”), (ii) have received all permits, licenses or other approvals required
of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in
compliance with all terms and conditions of any such permit, license or approval, except where such
noncompliance with Environmental Laws, failure to receive required permits, licenses or other
approvals or failure to comply with the terms and conditions of such permits, licenses or approvals
would not, singly or in the aggregate, have a Material Adverse Effect.

          (n) To the knowledge of the Company, there are no costs or liabilities associated with
Environmental Laws (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) which would, singly or in the aggregate, have a Material Adverse Effect.

          (o) The Company is not, and after giving effect to the offering and sale of the Securities and
the concurrent issuance and sale of the Common Stock and the application of the proceeds thereof as
described in the Final Memorandum, will not be, required to register as an “investment company” as
such term is defined in the Investment Company Act of 1940, as amended.

          (p) Neither the Company nor any of its Subsidiaries is in violation of its certificate of
incorporation or by-laws (or comparable corporate documents) and neither the Company nor any of its
Subsidiaries is in default in the performance or observance of any obligation, agreement, covenant
or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit
agreement, note, lease or other agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which it or any of them may be bound, or to which any of the property
or assets of the Company or any Subsidiary is subject, except for such violations or defaults that
are described in the Final Memorandum or would not result in a Material Adverse Effect.

          (q) Subsequent to the date as of which information is given in the Final Memorandum, (i)
neither the Company nor any of the Subsidiaries has incurred any material liability or obligation,
direct or contingent, nor entered into any material transaction, in each case, not in the ordinary
course of business or not described in or contemplated by the Final Memorandum; (ii) the Company
has not purchased any of its outstanding capital stock, nor declared, paid or otherwise made any
dividend or distribution of any kind on its capital stock (other than repurchases of unvested
shares of the Company’s capital stock pursuant to its equity incentive plans); and (iii) there has
not been any material change in the capital stock, short-term debt or long-term debt of the
Company, except in each case as described in or contemplated by the Final Memorandum.

          (r) The Company and its Subsidiaries own or have the right to use, or can acquire or obtain
the right to use on reasonable terms, adequate 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, trade names or
other intellectual property (collectively, “Intellectual Property”) necessary to carry on the
business now operated by them, except where the failure to own or have the right to use such
Intellectual Property would not, singly or in the aggregate, have a Material Adverse Effect, or
except as described in the Final Memorandum. Neither the Company nor any of its Subsidiaries has
received any notice or is otherwise aware of any infringement of or conflict with asserted rights
of others with respect to any Intellectual Property or of any facts or circumstances which would
render any Intellectual Property invalid or inadequate to protect the interest of the Company or
any of its Subsidiaries therein, and which infringement or conflict (if the subject of any
unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate,
would result in a Material Adverse Effect.

4

 

          (s) Except as described in the Final Memorandum, each of the Company and the Subsidiaries (i)
has all necessary licenses, consents, authorizations, approvals, orders, certificates and permits
of and from, and has made all declarations and filings, if any, with all federal, state and local
and foreign governmental, administrative or regulatory authorities and organizations, to own,
lease, license and use its properties and assets and to conduct its business in the manner
described in the Final Memorandum, including providing digital enhanced specialized mobile radio
services as currently conducted by them, except to the extent that the failure to obtain such
licenses, consents, authorizations, approvals, orders, certificates and permits or make such
declarations and filings, if any, would not have a Material Adverse Effect and (ii) has not
received any notice of proceedings relating to the violation, revocation or modification of any
such license, consent, authorization, approval, order, certificate or permit which, singly or in
the aggregate, if the subject of any unfavorable decision, ruling or finding, would reasonably be
expected to result in a Material Adverse Effect.

          (t) PricewaterhouseCoopers LLP, who have certified the financial statements and supporting
schedules for the Company incorporated by reference in the Final Memorandum, and Deloitte & Touche
LLP are each independent public accountants as required by the Securities Act and the rules and
regulations of the Commission thereunder.

          (u) The Company and each of the Subsidiaries maintain a system of internal accounting controls
sufficient to provide reasonable assurance that (i) transactions are executed in accordance with
management’s general or specific authorizations; (ii) transactions are recorded as necessary to
permit preparation of financial statements in conformity with U.S. 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
differences.

          (v) Except as disclosed or incorporated by reference in the Final Memorandum, the Company’s
internal control over financial reporting, as determined in Rule 13a-15(f) of the Exchange Act,
were evaluated for effectiveness by management of the Company and were determined to be effective
as of December 31, 2004, and since the date of the latest audited financial statements included in
the Final Memorandum, there has been no change in the Company’s internal control over financial
reporting that has materially adversely affected, or is reasonably likely to materially adversely
affect, the Company’s internal control over financial reporting.

          (w) Except as disclosed or incorporated by reference in the Final Memorandum, the Company
maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the
Exchange Act) that have been designed to ensure that information relating to the Company and its
subsidiaries that is required to be disclosed by the Company in the reports that it files or
submits under the Exchange Act is made known to the Company’s management, including its principal
executive officer and principal financial officer, and by others within those entities as
appropriate to allow timely decisions regarding required disclosure; such disclosure controls and
procedures were evaluated for effectiveness by management of the Company and were determined to be
effective as of June 30, 2005, and since the date of such evaluation, there have been no
significant changes in the disclosure controls and procedures that are reasonably likely to
materially adversely affect the disclosure controls and procedures.

          (x) Except as disclosed in the Final Memorandum, the Company is in compliance in all material
respects with applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations
promulgated in connection therewith that are effective as of the date hereof.

          (y) None of the Company or any of its Subsidiaries has committed any act in violation of the
Foreign Corrupt Practices Act, as amended, that would have a Material Adverse Effect.

5

 

          (z) Except as described in the Final Memorandum and except for the Registration Rights
Agreement, there are no contracts, agreements or understandings between the Company and any person
granting such person the right to require the Company to file a registration statement under the
Securities Act with respect to any securities of the Company or to require the Company to include
such securities with the Shares registered pursuant to the Registration Statement.

          (aa) Neither the Company nor any affiliate (as defined in Rule 501(b) of Regulation D under
the Securities Act, an “Affiliate”) of the Company has directly, or through any agent, (i) sold,
offered for sale, solicited offers to buy or otherwise negotiated in respect of, any security (as
defined in the Securities Act) which is or will be integrated with the sale of the Securities in a
manner that would require the registration under the Securities Act of the Securities or (ii)
offered, solicited offers to buy or sold the Securities by any form of general solicitation or
general advertising (as those terms are used in Regulation D under the Securities Act) or in any
manner involving a public offering within the meaning of Section 4(2) of the Securities Act.

          (bb) It is not necessary in connection with the offer, sale and delivery of the Securities to
the Initial Purchaser on the Closing Date in the manner contemplated by this Agreement to register
the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act
of 1939, as amended (the “TIA”).

          (cc) The Securities satisfy the requirements set forth in Rule 144A(d)(3) under the Securities
Act.

          2. Agreements to Sell and Purchase. Upon the basis of the representations and
warranties of the Initial Purchaser herein contained, the Company hereby agrees to sell to the
Initial Purchaser, and the Initial Purchaser, upon the basis of the representations and warranties
of the Company herein contained, but subject to the conditions hereinafter stated, agrees to
purchase from the Company $300,000,000 principal amount of Firm Securities at a purchase price of
97.5% of the principal amount thereof (the “Purchase Price”).

          On the basis of the representations and warranties contained in this Agreement, and subject to
its terms and conditions, the Company agrees to sell to the Initial Purchaser, and the Initial
Purchaser shall have the right to purchase up to $50,000,000 principal amount of Additional
Securities at the Purchase Price. The Initial Purchaser may exercise this right in whole or from
time to time in part by giving written notice of each election to exercise this right not later
than 30 days after the date of this Agreement. Any exercise notice shall specify the principal
amount of Additional Securities to be purchased by the Initial Purchaser and the date on which such
Additional Securities are to be purchased (the “Option Closing Date”). Each Option Closing Date
must be at least one business day after the written notice is given and may not be earlier than the
Closing Date (as defined in Section 4 hereof) nor later than ten business days after the date of
such notice. Additional Securities may be purchased as provided in Section 4.

          The Company hereby agrees that, without the prior written consent of the Initial Purchaser, it
will not, during the period ending 90 days after the date of the Final Memorandum, (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or
dispose of, directly or indirectly, any shares of its common stock, par value $0.001 per share (the
“Common Stock”), or any securities convertible into or exercisable or exchangeable for Common Stock
or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part,
any of the economic consequences of ownership of the Common Stock, whether any such transaction
described in clause (i) or (ii) above is to
be settled by delivery of Common Stock or such other securities, in cash or otherwise. The
foregoing

6

 

sentence shall not apply to (A) the issuance and sale of the Securities under this
Agreement and any issuance of Underlying Securities upon conversion of any Securities, (B) the
issuance by the Company of any shares of Common Stock upon the exercise of an option or warrant or
the conversion of a security outstanding on the date hereof, (C) the issuance or sale by the
Company of shares of Common Stock or any other security, other than securities substantially
similar to the Securities and convertible into shares of Common Stock, in consideration for or in
connection with the financing of the acquisition of stock, companies or assets, including spectrum
and (D) the granting of any options, deferred shares or other equity awards under the Company’s
equity incentive plans, so long as such options do not vest and become exercisable or such deferred
shares or other awards do not vest, in each case, in the absence of extraordinary events or
occurrences beyond the control of the grantee or recipient, until after the expiration of such
90-day period.

          3. Terms of Offering. The Initial Purchaser has advised the Company that it will make
an offering of the Securities purchased by the Initial Purchaser hereunder on the terms to be set
forth in the Final Memorandum, as soon as practicable after this Agreement is entered into as in
your judgment is advisable.

          4. Payment and Delivery. Payment for the Firm Securities shall be made to the Company
in Federal or other funds immediately available in New York City against delivery of such Firm
Securities for the account of the Initial Purchaser at 10:00 a.m., New York City time, on August
15, 2005, or at such other time on the same or such other date, not later than August 22, 2005, as
shall be designated in writing by the Initial Purchaser. The time and date of such payment are
hereinafter referred to as the “Closing Date.”

          Payment for any Additional Securities shall be made to the Company in Federal or other funds
immediately available in New York City against delivery of such Additional Securities for the
account of the Initial Purchaser at 10:00 a.m., New York City time, on the date specified in the
corresponding notice described in Section 2 or at such other time on the same or on such other
date, in any event not later than September 15, 2005, as shall be designated in writing by the
Initial Purchaser.

          The Securities shall be in definitive form or global form, as specified by the Initial
Purchaser, and registered in such names and in such denominations as the Initial Purchaser shall
request in writing not later than one full business day prior to the Closing Date or the applicable
Option Closing Date, as the case may be. The Securities shall be delivered to you on the Closing
Date or an Option Closing Date, as the case may be, for the account of the Initial Purchaser, with
any transfer taxes payable in connection with the transfer of the Securities to the Initial
Purchaser duly paid, against payment of the Purchase Price therefor.

          5. Conditions to the Initial Purchaser’s Obligations. The obligation of the Initial
Purchaser to purchase and pay for the Firm Securities on the Closing Date are subject to the
following conditions:

          (a) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date
and prior to any subsequent Option Closing Date:

Company’s securities by any “nationally recognized statistical rating organization,” as such
term is defined for purposes of Rule 436(g)(2) under the Securities Act; and

7

 

     (ii) there shall not have occurred any change, or any development involving a
prospective change, in the condition, financial or otherwise, or in the earnings, business
or operations of the Company and its Subsidiaries, taken as a whole, from that set forth in
the Final Memorandum (exclusive of any amendments or supplements thereto subsequent to the
date of this Agreement) that, in your judgment, is material and adverse and that makes it,
in your judgment, impracticable to market the Securities on the terms and in the manner
contemplated in the Final Memorandum.

          (b) The Initial Purchaser shall have received on the Closing Date a certificate, dated the
Closing Date and signed by an executive officer of the Company, to the effect set forth in Section
5(a)(i) above and to the effect that the representations and warranties of the Company contained in
this Agreement are true and correct as of the Closing Date and that the Company has complied with
all of the agreements and satisfied all of the conditions on its part to be performed or satisfied
hereunder on or before the Closing Date. The officer signing and delivering such certificate may
rely upon the best of his or her knowledge as to proceedings threatened.

          (c) The Initial Purchaser shall have received on the Closing Date an opinion of Williams

satisfactory to the Initial Purchaser, from each of PricewaterhouseCoopers LLP and Deloitte &
Touche LLP, independent public accountants, containing statements and information of the type
ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial
statements and certain financial information contained and incorporated by reference in the Final
Memorandum; provided that the letters delivered on the Closing Date shall use a “cut-off date” not
earlier than the date hereof.

          (g) The “lock-up” agreements, each substantially in the form of Exhibit C hereto, between the
Initial Purchaser and certain officers of the Company as set forth in Schedule II hereto relating
to sales and certain other dispositions of shares of Common Stock or certain other securities,
delivered to the Initial Purchaser on or before the date hereof, shall be in full force and effect
on the Closing Date.

          (h) At or prior to the Closing Date, the Company and the Trustee shall have executed and
delivered the Indenture, and the Company and the Initial Purchaser shall have executed and
delivered the Registration Rights Agreement in the form of Exhibit D hereto.

8

 

          (j) Counsel for the Initial Purchaser shall have been furnished with such documents as they
may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the
Securities herein contemplated, or in order to evidence the accuracy of any of the representations
or warranties or the fulfillment of any of the conditions herein contained.

          (k) The obligation of the Initial Purchaser to purchase Additional Securities hereunder is
subject to the delivery to the Initial Purchaser on each Option Closing Date of each of the
documents referred to above dated as of the Option Closing Date (except that insofar as any
documents relate to Securities, they may be limited to covering only Additional Securities).

          6. Covenants of the Company. In further consideration of the agreements of the
Initial Purchaser contained in this Agreement, the Company covenants with the Initial Purchaser as
follows:

          (a) To furnish to the Initial Purchaser in New York City, without charge, prior to 10:00 a.m.
New York City time on the business day next succeeding the date of this Agreement and during the
period mentioned in Section 6(c), as many copies of the Final Memorandum and any supplements and
amendments thereto as you may reasonably request.

          (b) Before amending or supplementing the Final Memorandum, to furnish to you a copy of each
such proposed amendment or supplement and not to use any such proposed amendment or supplement to
which the Initial Purchaser reasonably objects.

          (c) If, during such period after the date hereof and prior to the date on which all of the
Securities shall have been sold by the Initial Purchaser, any event shall occur or condition exist
as a result of which it is necessary to amend or supplement the Final Memorandum in order to make
the statements therein, in the light of the circumstances when the Final Memorandum is delivered to
a purchaser, not misleading, or if, in the opinion of counsel for the Initial Purchaser, it is
necessary to amend or supplement the Final Memorandum to comply with applicable law, forthwith to
prepare and furnish, at its own expense, to the Initial Purchaser, either amendments or supplements
to the Final Memorandum so that the statements in the Final Memorandum as so amended or
supplemented will not, in the light of the circumstances when the Final Memorandum is delivered to
a purchaser, be misleading or so that the Final Memorandum, as amended or supplemented, will comply
with applicable law.

          (d) To endeavor to qualify the Securities for offer and sale under the securities or Blue Sky
laws of such jurisdictions as you shall reasonably request.

          (e) Whether or not the transactions contemplated in this Agreement are consummated or this
Agreement is terminated, to pay or cause to be paid all expenses (which shall not include any
Initial Purchaser’s discounts or commissions payable to the Initial Purchaser) incident to the
performance of its obligations under this Agreement, including: (i) the fees, disbursements and
expenses of the Company’s counsel and the Company’s accountants in connection with the issuance and
sale of the Securities and all other fees or expenses in connection with the preparation of each
Memorandum and all amendments and supplements to any of the foregoing, including all printing costs
associated therewith, and the mailing and delivering of copies thereof to the Initial Purchaser, in
the quantities herein above
specified, (ii) all costs and expenses related to the transfer and delivery of the Securities
to the Initial Purchaser, including any transfer or other taxes payable thereon, (iii) the cost of

sale of the Securities under state securities laws and all expenses in connection with the
qualification of the Securities for offer and sale under state securities laws as provided in
Section 6(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for

9

Company relating to investor presentations on any “road show” undertaken in connection with the
marketing of the offering of the Securities, including, without limitation, expenses associated
with the production of road show slides and graphics, fees and expenses of any consultants engaged
in connection with the road show presentations with the prior approval of the Company, travel and
lodging expenses of the representatives and officers of the Company and any such consultants, and
the cost of any aircraft chartered in connection with the road show, (ix) the document production
charges and expenses associated with printing this Agreement, the Indenture and the Registration
Rights Agreement and (x) all other costs and expenses incident to the performance of the
obligations of the Company hereunder for which provision is not otherwise made in this Section. It
is understood, however, that except as provided in this Section, Section 8 entitled “Indemnity and
Contribution”, and the last paragraph of Section 10 below, the Initial Purchaser will pay all of
its costs and expenses, including fees and disbursements of its counsel, transfer taxes payable on
resale of any of the Securities by it and any advertising expenses connected with any offers it may
make.

          (f) Not to, and use its reasonable best efforts to ensure that no Affiliate will, sell, offer
for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in
the Securities Act) which could be integrated with the sale of the Securities in a manner which
would require the registration under the Securities Act of the Securities.

          (g) Not to solicit any offer to buy or offer or sell the Securities or the Underlying
Securities by means of any form of general solicitation or general advertising (as those terms are
used in Regulation D under the Securities Act) or in any manner involving a public offering within
the meaning of Section 4(2) of the Securities Act.

          (h) While any of the Securities or the Underlying Securities remain “restricted securities”
within the meaning of the Securities Act, to make available, upon request, to any seller of such
Securities the information specified in Rule 144A(d)(4) under the Securities Act, unless the
Company is then subject to Section 13 or 15(d) of the Exchange Act.

          (i) If requested by the Initial Purchaser, to use its reasonable best efforts to permit the
Securities to be designated PORTAL securities in accordance with the rules and regulations adopted
by the National Association of Securities Dealers, Inc. relating to trading in the PORTAL Market.

          (j) During the period of two years after the Closing Date or any Option Closing Date, if
later, the Company will not resell, and will use its best efforts to prevent its affiliates (as
such term is defined in Rule 144 under the Securities Act) from reselling, any of the Securities or
the Underlying Securities which constitute “restricted securities” under Rule 144 that have been
acquired by any of them.

          (k) Not to take any action prohibited by Regulation M under the Exchange Act in connection
with the distribution of the Securities contemplated hereby.

          7. Offering of Securities; Restrictions on Transfer. The Initial Purchaser represents
and warrants that the Initial Purchaser is a qualified institutional buyer as defined in Rule 144A
under the Securities Act (a “QIB”). The Initial Purchaser agrees with the Company that (i) it has
not solicited and will not solicit offers for, or offer or sell, such Securities by any form of
general solicitation or general

10

 

advertising (as those terms are used in Regulation D under the
Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of
the Securities Act and (ii) it will solicit offers for such Securities only from, and will offer
such Securities only to, persons that it reasonably believes to be QIBs that in purchasing such
Securities are deemed to have represented and agreed as provided in the Final Memorandum under the
caption “Transfer Restrictions.”

          8. Indemnity and Contribution. (a) The Company will indemnify and hold harmless the
Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which
such Initial Purchaser may become subject, under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Memorandum or the Final Memorandum, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a material fact
necessary to make the statements therein in light of the circumstances under which they were made
not misleading, and will reimburse the Initial Purchaser for any legal or other expenses reasonably
incurred by such Initial Purchaser in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that the Company shall not be liable in any
such case to the extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged omission made in any
Preliminary Memorandum or the Final Memorandum or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by or on behalf of the Initial
Purchaser expressly for use therein.

          (b) The Initial Purchaser will indemnify and hold harmless the Company against any losses,
claims, damages or liabilities to which the Company may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Memorandum or the Final Memorandum, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to state therein a
material fact or necessary to make the statements therein in light of the circumstances under which
they were made 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 any Preliminary
Memorandum or the Final Memorandum or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of such Initial
Purchaser expressly for use therein; and will reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending any such action or
claim as such expenses are incurred.

          (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice
of the commencement of any action, such indemnified party shall, if a claim in respect thereof is
to be made against the indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the indemnifying party shall not
relieve it
from any liability which it may have to any indemnified party otherwise than under such
subsection. In case any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party (who shall not, except with the consent of the indemnified party, be counsel
to the indemnifying party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party under such subsection for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying party shall, without
the written consent of the indemnified party, effect the settlement or

11

 

compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or claim in respect of
which indemnification or contribution may be sought hereunder (whether or not the indemnified party
is an actual or potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all liability arising
out of such action or claim and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act, by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to
hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party 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 the relative benefits received by the Company on the one
hand and the Initial Purchaser on the other from the offering of the Securities. If, however, the
allocation provided by the immediately preceding sentence is not permitted by applicable law or if
the indemnified party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such indemnified party in
such proportion as is appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Initial Purchaser on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or liabilities (or actions
in respect thereof), as well as any other relevant equitable considerations including, but not
limited to, the timeliness of the notice given as required by Section 8(c). The relative benefits
received by the Company on the one hand and the Initial Purchaser on the other shall be deemed to
be in the same proportion as the total net proceeds from the offering (before deducting expenses)
received by the Company bear to the total discounts to the price to the public at which the Initial
Purchaser purchased the Securities from the Company and commissions received by the Initial
Purchaser, in each case as set forth in the Final Memorandum. The relative fault 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 Purchaser on the other and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Initial Purchaser agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation
(even if the Initial Purchaser was treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations referred to above in this
subsection (d). The amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), the Initial Purchaser shall not be required to contribute any
amount in excess of the amount by which the total price at which the Securities purchased by it and
resold to investors were
offered to investors exceeds the amount of any damages which such Initial Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission.

          (e) The obligations of the Company under this Section 8 shall be in addition to any liability
which the Company may otherwise have and shall extend, upon the same terms and conditions, to the
Initial Purchaser and each person, if any, who controls the Initial Purchaser within the meaning of
the Act; and the obligations of the Initial Purchaser under this Section 8 shall be in addition to
any liability which the Initial Purchaser may otherwise have and shall extend, upon the same terms
and conditions, to the Company, to each officer and director of the Company and to each person, if
any, who controls the Company within the meaning of the Securities Act.

12

 

          9. Termination. The Initial Purchaser may terminate this Agreement by notice to the
Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i)
trading generally shall have been suspended or materially limited on, or by, as the case may be,
any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the
Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade,
(ii) trading of any securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance
services in the United States shall have occurred, (iv) any moratorium on commercial banking
activities shall have been declared by Federal or New York State authorities or (v) there shall
have occurred any outbreak or escalation of hostilities, or any change in financial markets,
currency exchange rates or controls or any calamity or crisis that, in your judgment, is material
and adverse and which, singly or together with any other event specified in this clause (v), makes
it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of
the Securities on the terms and in the manner contemplated in the Final Memorandum.

          10. Effectiveness. This Agreement shall become effective upon the execution and
delivery hereof by the parties hereto.

          If this Agreement shall be terminated by the Initial Purchaser because of any failure or
refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of
this Agreement, or if for any reason the Company shall be unable to perform its obligations under
this Agreement, the Company will reimburse the Initial Purchaser for all out-of-pocket expenses
(including the fees and disbursements of their counsel) reasonably incurred by the Initial
Purchaser in connection with this Agreement or the offering contemplated hereunder.

          11. Counterparts. This Agreement may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.

          12. Applicable Law. This Agreement shall be governed by and construed in accordance
with the internal laws of the State of New York.

          13. Headings. The headings of the sections of this Agreement have been inserted for convenience of
reference only and shall not be deemed a part of this Agreement.

13

 

          14. Absence of Fiduciary Relationship. The Company acknowledges and agrees that (a)
the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial
transaction between the Company, on the one hand, and the Initial Purchaser, on the other, (b) in
connection therewith and with the process leading to such transaction the Initial Purchaser is
acting solely as a principal and not the agent or fiduciary of the Company, (c) the Initial
Purchaser has not assumed an advisory or fiduciary responsibility in favor of the Company with
respect to the offering contemplated hereby or the process leading thereto (irrespective of whether
the Initial Purchaser has advised or is currently advising the Company on other matters) or any
other obligation to the Company except the obligations expressly set forth in this Agreement and
(d) the Company has consulted its own legal and financial advisors to the extent it deemed
appropriate. The Company agrees that it will not claim that the Initial Purchaser has acted in any
capacity other than as initial purchaser pursuant to this Agreement, or owes any fiduciary duty to
the Company, in connection with the offering, purchase or sale of the Securities or the process
leading thereto.

          15. Entire Agreement. This Agreement supersedes all prior agreements and
understandings (whether written or oral) between the Company and the Initial Purchaser with respect
to the subject matter hereof.

          16. Waiver of Jury Trial. The Company and the Initial Purchaser hereby irrevocably
waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any

good standing under the laws of the jurisdiction of its incorporation, has the corporate
power and authority to own its property and to conduct its business as described in the
Final Memorandum and is duly qualified to transact business and is in good standing in each
jurisdiction in which the conduct of its business or its ownership or leasing of property
requires such qualification, except to the extent that the failure to be so qualified or be

Subsidiary” and collectively, the “U.S. Subsidiaries”) has been duly incorporated, is
validly existing as a corporation in good standing under the laws of the jurisdiction of its
incorporation, has the corporate power and authority to own its property and to conduct its
business as described in the Final Memorandum and is duly qualified to transact business and

     (vii) The Securities have been duly authorized and, when executed and authenticated by
the Trustee in accordance with the provisions of the Indenture and delivered to and paid for
by the Initial Purchaser in accordance with the terms of this Agreement, will be valid and
binding obligations of the Company, enforceable in accordance with their terms, except as
the enforceability thereof may be limited by (A) bankruptcy, insolvency, reorganization,

enforceable in accordance with its terms, except as the enforceability thereof may be
limited by (A) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
similar laws affecting the enforcement of creditors’ rights generally, (B) general
principles of equity (regardless of whether enforceability is considered in an action at law
or a suit in equity), including the availability of equitable remedies (C) procedural
requirements of law applicable to the exercise of creditors’ rights generally, and (D) as to

provisions relating to indemnification or contribution.

     (x) The execution and delivery by the Company of, and the performance by the Company of
its obligations under, this Agreement, the Indenture, the Registration Rights Agreement and
the Securities will not contravene (A) any provision of law applicable to the Company, (B)
the Restated Certificate of Incorporation or Amended and Restated Bylaws of the Company, (C)
the terms of any agreement or other instrument to be listed on a schedule hereto, or (D) to
counsel’s knowledge, any judgment, order or decree of any governmental body, agency or court
having jurisdiction over the Company or any U.S. Subsidiary, except, with respect to clauses
(A) and (C), to the extent that any contravention would not have a Material Adverse Effect.

     (xi) No consent, approval, authorization or order of, or qualification with, any
governmental body or agency is required for the performance by the Company of its
obligations under this Agreement, the Indenture, the Registration Rights Agreement or the
Securities, except (A) such as have been obtained or as may be required by the securities or
Blue Sky laws of the various states in connection with the offer and sale of the Securities
(as to which such counsel need not express any opinion), (B) and by federal and state
securities or Blue Sky laws with respect to the Company’s obligations under the Registration
Rights Agreement and as to which the failure to so obtain would not materially and (C)
adversely affect the ability of the Company to perform its obligations under this Agreement,
the Indenture, the Registration Rights Agreement or the Securities.

     (xii) The Company is not, and after giving effect to the offering and sale of the
Securities and the application of the proceeds thereof as described in the Final Memorandum
will not be, required to register as an “investment company” as such term is defined in the
Investment Company Act of 1940, as amended.

     (xiii) When the Securities are issued and delivered pursuant to the Purchase Agreement,
none of the Securities will be of the same class (within the meaning of Rule 144A under the
Securities Act) as securities of the Company that are listed on a national securities
exchange registered under Section 6 of the Exchange Act or that are quoted in a United
States automated inter-dealer quotation system;

     (xiv) The statements relating to legal matters, documents or proceedings included in
the Final Memorandum under the captions “Description of Notes,” “Description of Capital
Stock” and “Transfer Restrictions,” in each case, fairly summarize, in all material
respects, such matters, documents or proceedings.

A-2

 

     (xv) The statements in the Final Memorandum under the caption “Certain United States
Tax Considerations,” insofar as such statements constitute a summary of the United States
federal tax laws referred to therein, are accurate and fairly summarize in all material
respects the United States federal tax laws referred to therein.

     (xvi) Each document filed pursuant to the Exchange Act and incorporated by reference in
the Final Memorandum (except for the financial statements, notes thereto and schedules and
other financial, numerical, statistical and accounting information and data included or
incorporated by reference therein (collectively, the “Excluded Information”), as to which
such counsel need not express any opinion), on the date such document was filed with the
Commission, complied as to form in all material respects with the requirements of the
Exchange Act and the applicable rules and regulations of the Commission thereunder.

     (xvii) Assuming (A) the accuracy of, and compliance with, the representations,
warranties and agreements of the Company and the Initial Purchaser in this Agreement and (B)
that each person to whom the Initial Purchaser offers, sells or delivers the Securities is a
qualified institutional buyer as defined in Rule 144A under the Securities Act, or a person
(other than a U.S. person) outside the United States in reliance on Regulation S under the
Securities Act, it is not necessary in connection with the offer, sale and delivery of the
Securities on the Closing Date to the Initial Purchaser under this Agreement or in
connection with the initial resale of such Securities by the Initial Purchaser as
contemplated by and in accordance with this Agreement to register the Securities under the
Securities Act or to qualify the Indenture under the Trust Indenture Act of 1939, as
amended.

     (xviii) To such counsel’s knowledge, there are no legal or governmental proceedings
pending or threatened to which the Company or any of its Subsidiaries is or may be a party
or to which any of the properties of the Company or any of its Subsidiaries is or may be
subject that are required to be described in the Final Memorandum and are not so described
or of any statutes, regulations, contracts or other documents that are required to be
described in the Final Memorandum that are not described as required.

     In addition, such counsel shall state that nothing has come to the attention of such counsel
that causes such counsel to believe that the Final Memorandum (except for the Excluded Information,
as to which such counsel need not express any opinion) as of its date or as of the Closing Date
contained or contains an untrue statement of a material fact or omitted or omits 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.

     With respect to the immediately preceding paragraph, Williams Mullen may state that their
beliefs are based upon their participation in the preparation of the Final Memorandum and any
amendments or supplements thereto and review and discussion of the contents thereof, but are
without independent check or verification, except as specified.

be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (a “Shelf
Registration Statement”) registering the resale from time to time by Holders thereof of all of the

Registration Statement shall be on Form S-3 or another appropriate form permitting registration of

distribution elected by the Holders and set forth in the Initial Shelf Registration Statement. The
Company shall use its reasonable best efforts to cause the Initial

D-3

 

Shelf Registration Statement to be declared effective under the Securities Act as promptly as
is practicable but in any event by the date (the “Effectiveness Deadline Date”) that is one hundred
eighty (180) days after the Issue Date, and, except as otherwise provided herein, to keep the
Initial Shelf Registration Statement (or any Subsequent Shelf Registration Statement) continuously
effective under the Securities Act until the expiration of the Effectiveness Period. At the time

Holder on or prior to the date ten (10) Business Days prior to such time of effectiveness shall be
named as a selling securityholder in the Initial Shelf Registration Statement and the related
Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of
Registrable Securities in accordance with applicable law. None of the Company’s security holders
(other than the Holders of Registrable Securities) shall have the right to include any of the

Offering Memorandum of the Company dated August 10, 2005.

     (b) If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement
ceases to be effective for any reason at any time during the Effectiveness Period (other than
because all Registrable Securities registered thereunder shall have been resold pursuant thereto or
shall have otherwise ceased to be Registrable Securities), the Company shall use its reasonable
best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and
in any event shall within thirty (30) days of such cessation of effectiveness amend the Shelf
Registration Statement in a manner reasonably expected to obtain the withdrawal of the order
suspending the effectiveness thereof, or file an additional Shelf Registration Statement (a
“Subsequent Shelf Registration Statement”) covering all of the securities that as of the date of
such filing are Registrable Securities. If a Subsequent Shelf Registration Statement is filed, the
Company shall use its reasonable best efforts to cause the Subsequent Shelf Registration Statement
to become effective as promptly as is practicable after such filing and to keep such Registration
Statement (or subsequent Shelf Registration Statement) continuously effective until the expiration
of the Effectiveness Period.

     (c) The Company shall supplement and amend the Shelf Registration Statement if required by the
rules, regulations or instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or as otherwise required by the Securities Act or as necessary to name
a Notice Holder as a selling securityholder pursuant to Section 2(d) below.

     (d) Each Holder agrees that if such Holder wishes to sell Registrable Securities pursuant to a
Shelf Registration Statement and related Prospectus, it will do so only in accordance with this
Section 2(d) and Section 3(h). Following the date that the Initial Shelf Registration Statement is
declared effective, each Holder wishing to sell Registrable Securities pursuant to a Shelf
Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the
Company at least three (3) Business Days prior to any intended distribution of Registrable
Securities under the Shelf Registration Statement. Each Holder who elects to sell Registrable
Securities pursuant to a Shelf Registration Statement agrees, by submitting a Notice and
Questionnaire to the Company, it will be bound by the terms and conditions of the Notice and
Questionnaire and this Agreement. From and after the date the Initial Shelf Registration Statement
is declared effective, the Company shall, as promptly as practicable after the date a Notice and
Questionnaire is delivered pursuant to Section 9(c) hereof, and in any event upon the later of (x)
seven (7) Business Days after such date or (y) seven (7) Business Days after the expiration of any
Deferral Period that is in effect when the Notice and Questionnaire is delivered or that is put
into effect within seven (7) Business Days of such delivery date:

     (i) if required by applicable law, file with the SEC a post-effective amendment to the
Shelf Registration Statement or prepare and, if required by applicable law, file a
supplement to the related Prospectus or a supplement or amendment to any document
incorporated therein by reference or file any other required document so that the Holder
delivering such Notice and

D-4

 

Questionnaire is named as a selling securityholder in the Shelf Registration Statement
and the related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of the Registrable Securities in accordance with applicable law
and, if the Company shall file a post-effective amendment to the Shelf Registration
Statement, use its reasonable best efforts to cause such post-effective amendment to be
declared effective under the Securities Act as promptly as is practicable, but in any event
by the date (the “Amendment Effectiveness Deadline Date”) that is sixty (60) days after the
date such post-effective amendment is required by this clause to be filed; and

     (ii) provide such Holder copies of any documents filed pursuant to Section 2(d)(i);
provided that if such Notice and Questionnaire is delivered during a Deferral Period, the
Company shall so inform the Holder delivering such Notice and Questionnaire. The Company
shall notify such Holder as promptly as practicable after the effectiveness under the
Securities Act of any post-effective amendment filed pursuant to Section 2(d)(i).
Notwithstanding anything contained herein to the contrary, (i) the Company shall be under no
obligation to name any Holder that is not a Notice Holder as a selling securityholder in any
Registration Statement or related Prospectus and (ii) the Amendment Effectiveness Deadline
Date shall be extended by up to seven (7) Business Days from the expiration of a Deferral
Period (and the Company shall incur no obligation to pay Liquidated Damages during such
extension or during such Deferral Period) if such Deferral Period shall be in effect on the
Amendment Effectiveness Deadline Date.

(e) The parties hereto agree that the Holders of Registrable Securities will suffer damages,
and that it would not be feasible to ascertain the extent of such damages with precision, if, other
than as permitted hereunder:

     (i) the Initial Shelf Registration Statement has not been filed on or prior to the
Filing Deadline Date;

     (ii) the Initial Shelf Registration Statement has not been declared effective under the
Securities Act on or prior to the Effectiveness Deadline Date;

     (iii) the Company has failed to perform its obligations set forth in Section 2(d)(i)
within the time period required therein;

     (iv) any post-effective amendment to a Shelf Registration Statement filed pursuant to
Section 2(d)(i) has not become effective under the Securities Act on or prior to the
Amendment Effectiveness Deadline Date; or

     (v) the aggregate duration of Deferral Periods in any period exceeds the number of days
permitted in respect of such periods pursuant to Section 3(h) hereof.

Each event described in any of the foregoing clauses (i) through (v) is individually referred to
herein as an “Event.” For purposes of this Agreement, each Event set forth above shall begin and
end on the dates set forth in the table below:

For purposes of this Agreement, Events shall begin on the dates set forth in the table above and
shall continue until the ending dates set forth in the table above.

     Commencing on (and including) any date that an Event has begun and ending on (but excluding)
the next date on which there are no Events that have occurred and are continuing (a “Damages
Accrual Period”), the Company shall pay interest (“Liquidated Damages Amount”), as liquidated
damages and not as a penalty, to Record Holders of Registrable Securities, or shall issue
additional shares of Common Stock, as applicable, as set forth below:

	 	(A)	 	in respect of any Note that is a Registrable Security, the Company agrees to
pay interest accruing for each day in the Damages Accrual Period at a rate per annum
equal to 0.5% of the principal amount of such Note;
	 
	 	(B)	 	in respect of any Note that is a Registrable Security and is submitted by a
Holder for conversion into Underlying Common Stock during a Damages Accrual Period, the
Company agrees (i) to pay on the settlement date in respect to such conversion,
interest accruing for each day commencing on (and including) the first day of such
Damages Accrual Period and ending on (but excluding) such settlement date at a rate per
annum equal to 0.5% of the principal amount of such Note and (ii) to issue and deliver
in respect of each $1,000 principal amount of Notes submitted for conversion,
additional shares of Underlying Common Stock equal to 3% of the Applicable Conversion
Rate (as defined in the Indenture) (except to the extent the Company elects to deliver
cash upon conversion in accordance with terms of the Indenture); and

D-6

 

	 	(C)	 	in respect of Common Stock, each Holder of such Common Stock will not be
entitled to any Liquidated Damages Amount;

provided that in the case of a Damages Accrual Period that is in effect solely as a result of an
Event of the type described in clause (iii) or (iv) of the preceding paragraph, such Liquidated
Damages Amount shall be paid only to the Holders (as set forth in the succeeding paragraph) that
have delivered Notices and Questionnaires that caused the Company to incur the obligations set
forth in Section 2(d) the non-performance of which is the basis of such Event. Notwithstanding the
foregoing, no Liquidated Damages Amount shall accrue as to any Registrable Security from and after
the earlier of (x) the date such security is no longer a Registrable Security and (y) expiration of
the Effectiveness Period. The rate of accrual of the Liquidated Damages Amount with respect to any
period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of
multiple concurrent Events.

     The Liquidated Damages Amount shall accrue from the first day of the applicable Damages
Accrual Period, and shall be payable on each Damages Payment Date during the Damage Accrual Period
(and on the Damages Payment Date next succeeding the end of the Damages Accrual Period if the
Damage Accrual Period does not end on a Damages Payment Date) to the Record Holders of the
Registrable Securities entitled thereto; provided that any Liquidated Damages Amount accrued with
respect to any Note or portion thereof redeemed by the Company on a redemption date or converted
into Underlying Common Stock on a conversion date prior to the Damages Payment Date, shall, in any
such event, be paid instead to the Holder who submitted such Note or portion thereof for redemption
or conversion on the applicable redemption date or settlement date with respect to such conversion,
as the case may be, on such date (such settlement date promptly following the conversion date, in
the case of conversion); provided further that, in the case of an Event of the type described in
clause (iii) or (iv) of the first paragraph of this Section 2(e), such Liquidated Damages Amount
shall be paid only to the Holders entitled thereto pursuant to such first paragraph by check mailed
to the address set forth in the Notice and Questionnaire delivered by such Holder. Any shares of
Underlying Common Stock that are payable pursuant to Section 2(e)(B)(ii) herein will be payable on
the date on which other shares of Underlying Common Stock otherwise deliverable are required to be
delivered by the Company pursuant to Section 14.02 of the Indenture. The Trustee shall be
entitled, on behalf of registered holders of Notes or Underlying Common Stock, to seek any
available remedy for the enforcement of this Agreement, including for the payment of such
Liquidated Damages Amount. Notwithstanding the foregoing, the parties agree that the sole damages
payable for a violation of the terms of this Agreement with respect to which liquidated damages are
expressly provided shall be such liquidated damages. Nothing shall preclude any Holder from
pursuing or obtaining specific performance or other equitable relief with respect to this Agreement
in accordance with applicable law.

     All of the Company’s obligations set forth in this Section 2(e) that are outstanding with
respect to any Registrable Security at the time such security ceases to be a Registrable Security
shall survive until such time as all such obligations with respect to such security have been
satisfied in full (notwithstanding termination of this Agreement pursuant to Section 9(k)).

     The parties hereto agree that the liquidated damages provided for in this Section 2(e)
constitute a reasonable estimate of the damages that may be incurred by Holders of Registrable
Securities by reason of the failure of the Shelf Registration Statement to be filed or declared
effective or available for effecting resales of Registrable Securities in accordance with the
provisions hereof.

D-7

 

          SECTION 3. Registration Procedures. In connection with the registration obligations of the
Company under Section 2 hereof, during the Effectiveness Period, the Company shall:

     (a) Prepare and file with the SEC a Registration Statement or Registration Statements on any
appropriate form under the Securities Act available for the sale of the Registrable Securities by
the Holders thereof in accordance with the intended method or methods of distribution thereof, and
use its reasonable best efforts to cause each such Registration Statement to become effective and

Securities Act; and use its reasonable best efforts to comply with the provisions of the Securities
Act applicable to it with respect to the disposition of all securities covered by such Registration
Statement during the Effectiveness Period in accordance with the intended methods of disposition by
the sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so
supplemented.

declared effective, (ii) of any request, following the effectiveness of the Initial Shelf
Registration Statement under the Securities Act, by the SEC or any other federal or state
governmental authority for amendments or supplements to any Registration Statement or related

provisions of Section 3(h) shall apply.

     (d) Use its reasonable best efforts to obtain the withdrawal of any order suspending the
effectiveness of a Registration Statement or the lifting of any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in
which they have been qualified for sale, in either case at the earliest possible moment, and
provide immediate notice to each Notice Holder and the Initial Purchaser of the withdrawal of any
such order.

     (e) As promptly as practicable furnish to each Notice Holder, the Special Counsel, if any, and
the Initial Purchaser, upon request and without charge, at least one (1) conformed copy of the

charge, as many copies of the Prospectus relating to such Registrable Securities (including each
preliminary prospectus) and any amendment or supplement thereto as such persons may reasonably
request; and the Company hereby consents (except during such periods that a Deferral Notice is
outstanding and has not been revoked) to the use of such Prospectus or each amendment or supplement
thereto by each Notice Holder in connection with any offering and sale of the Registrable
Securities covered by such Prospectus or any amendment or supplement thereto in the manner set

exemption from such registration or qualification) of such Registrable Securities for offer and
sale under the securities or Blue Sky laws of such jurisdictions within the United States as any
Notice Holder reasonably requests in writing (which request may be included in the Notice and
Questionnaire); prior to any public offering of the Registrable Securities pursuant to the
Registration Statement, use its reasonable best efforts to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period in connection with
such Notice Holder’s offer and sale of Registrable Securities pursuant to such registration or
qualification (or exemption therefrom) and do any and all other acts or things reasonably necessary
or advisable to enable the disposition in such jurisdictions of such Registrable Securities in the
manner set forth in the relevant Registration Statement and the related Prospectus; provided that
the Company will not be required to (i) qualify as a foreign corporation or as a dealer in
securities in any jurisdiction where it would not otherwise be required to qualify but for this
Agreement or (ii) take any action that would subject it to general service of process or to
taxation in any such jurisdiction where it is not then so subject.

     (h) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of any
Registration Statement or the initiation of proceedings with respect to any Registration Statement
under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence
of any fact (a “Material Event”) as a result of which any Registration Statement shall contain any
untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, or any Prospectus shall contain
any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or (C) the occurrence or existence of any pending corporate
development that, in the reasonable discretion of the Company, makes it appropriate to suspend the
availability of any Registration Statement and the related Prospectus:

     (i) in the case of clause (B) above, subject to the next sentence, as promptly as
practicable prepare and file, if necessary pursuant to applicable law, a post-effective
amendment to such Registration Statement or a supplement to the related Prospectus or any
document incorporated therein by reference or file any other required document that would be
incorporated by reference into such Registration Statement and Prospectus so that such
Registration Statement does not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the statements
therein not misleading, and such Prospectus does not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which they were
made, not misleading, as thereafter delivered to the purchasers of the Registrable
Securities being sold thereunder, and, in the case of a post-effective amendment to a
Registration Statement, subject to the next sentence, use its reasonable best efforts to
cause it to be declared effective as promptly as is practicable, and

D-9

 

     (ii) give notice to the Notice Holders and the Special Counsel, if any, that the
availability of the Shelf Registration Statement is suspended (a “Deferral Notice”) and,
upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable
Securities pursuant to the Registration Statement until such Notice Holder’s receipt of
copies of the supplemented or amended Prospectus provided for in clause (i) above, or until
it is advised in writing by the Company that the Prospectus may be used, and has received
copies of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such Prospectus.

The Company will use its reasonable best efforts to ensure that the use of the Prospectus may be
resumed (x) in the case of clause (A) above, as promptly as is practicable, (y) in the case of
clause (B) above, as soon as, in the sole judgment of the Company, public disclosure of such
Material Event would not be prejudicial to or contrary to the interests of the Company or, if
necessary to avoid unreasonable burden or expense, as soon as practicable thereafter, and (z) in
the case of clause (C) above, as soon as, in the reasonable discretion of the Company, such
suspension is no longer appropriate. The Company shall be entitled to exercise its right under
this Section 3(h) to suspend the availability of any Registration Statement or any Prospectus,
without incurring or accruing any obligation to pay liquidated damages pursuant to Section 2(e)
(the “Deferral Period”); provided that the aggregate duration of any Deferral Periods shall not
exceed 30 days in any three month period (or 60 days in any three month period in the event of a
Material Event pursuant to which the Company has delivered a second notice as required below) or 90
days in any twelve (12) month period; provided that in the case of a Material Event relating to an
acquisition or a probable acquisition or financing, recapitalization, business combination or other
similar transaction, the Company may, without incurring any obligation to pay liquidated damages
pursuant to Section 2(e), deliver to Notice Holders a second notice to the effect set forth above,
which shall have the effect of extending the Deferral Period by up to an additional 30 days, or
such shorter period of time as is specified in such second notice.

     (i) If reasonably requested in writing in connection with a disposition of Registrable
Securities pursuant to a Registration Statement, make reasonably available for inspection during
normal business hours by a representative for the Notice Holders of such Registrable Securities,
any broker-dealers, underwriters, attorneys and accountants retained by such Notice Holders, and
any attorneys or other agents retained by a broker-dealer or underwriter engaged by such Notice
Holders, all relevant financial and other records and pertinent corporate documents and properties
of the Company and its subsidiaries, and cause the appropriate officers, directors and employees of
the Company and its subsidiaries to make reasonably available for inspection during normal business
hours on reasonable notice all relevant information reasonably requested by such representative for
the Notice Holders, or any such broker-dealers, underwriters, attorneys or accountants in
connection with such disposition, in each case as is customary for similar “due diligence”
examinations; provided that such persons shall first agree in writing with the Company that any
information that is reasonably designated by the Company as confidential at the time of delivery of
such information shall be kept confidential by such persons and shall be used solely for the
purposes of exercising rights under this Agreement, unless (i) disclosure of such information is
required by court or administrative order or is necessary to respond to inquiries of regulatory
authorities, (ii) disclosure of such information is required by law (including any disclosure
requirements pursuant to federal securities laws in connection with the filing of any Registration
Statement or the use of any Prospectus referred to in this Agreement), (iii) such information
becomes generally available to the public other than as a result of a disclosure or failure to
safeguard by any such person or (iv) such information becomes available to any such person from a
source other than the Company and such source is not bound by a confidentiality agreement; and
provided further that the foregoing inspection and information gathering shall, to the greatest
extent possible, be coordinated on behalf of all the Notice Holders and the other parties entitled
thereto by Special Counsel, if any, or another representative selected by a majority of Registrable
Securities being sold by such Holders

D-10

 

pursuant to such Registration Statement. Any person legally compelled or required by
administrative or court order or by a regulatory authority to disclose any such confidential
information made available for inspection shall provide the Company with prompt prior written
notice of such requirement so that the Company may seek a protective order or other appropriate
remedy.

     (j) Comply with all applicable rules and regulations of the SEC and make generally available
to its securityholders earning statements (which need not be audited) satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under
the Securities Act) for a 12-month period commencing on the first day of the first fiscal quarter
of the Company commencing after the effective date of a Registration Statement, which statements
shall be made available no later than 45 days after the end of the 12-month period or 90 days if
the 12-month period coincides with the fiscal year of the Company.

     (k) Cooperate with each Notice Holder to facilitate the timely preparation and delivery of
certificates representing Registrable Securities sold or to be sold pursuant to a Registration
Statement, which certificates shall not bear any restrictive legends, and cause such Registrable
Securities to be in such denominations as are permitted by the Indenture and registered in such
names as such Notice Holder may request in writing at least two (2) Business Days prior to any sale
of such Registrable Securities.

     (l) Provide a CUSIP number for all Registrable Securities covered by each Registration
Statement not later than the effective date of such Registration Statement and, if requested,
provide the Trustee and the transfer agent for the Common Stock with printed certificates for the
Registrable Securities that are in a form eligible for deposit with The Depository Trust Company.

     (m) Cooperate and assist in any filings required to be made with the National Association of
Securities Dealers, Inc.

     (n) In the case of a Registration Statement involving an underwritten offering, the Company
shall enter into such customary agreements (including, if requested, an underwriting agreement in
reasonably customary form) and take all such other action, if any, as Holders of a majority of the
Registrable Securities being sold or any managing underwriters reasonably shall request in order to
facilitate any disposition of Notes and Underlying Common Stock pursuant to such Registration
Statement, including, without limitation, (i) using its reasonable best efforts to cause its
counsel to deliver an opinion or opinions in reasonably customary form, (ii) using its reasonable
best efforts to cause its officers to execute and deliver all customary documents and certificates
and (iii) using its reasonable best efforts to cause its independent public accountants to provide
a comfort letter or letters in reasonably customary form.

     (o) Upon (i) the filing of the Initial Shelf Registration Statement and (ii) the effectiveness
of the Initial Shelf Registration Statement, announce the same, in each case by release to Reuters
Economic Services and Bloomberg Business News.

          SECTION 4. Holder’s Obligations. Each Holder agrees, by acquisition of the Registrable
Securities, that no Holder shall be entitled to sell any of such Registrable Securities pursuant to
a Registration Statement or to receive a Prospectus relating thereto unless such Holder has
furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(d) hereof
(including the information required to be included in such Notice and Questionnaire) and the
information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the
Company all information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading and any other information regarding
such Notice Holder and the distribution of such Registrable Securities as the Company may from time
to time reasonably request. Any sale of any

D-11

 

Registrable Securities by any Holder shall constitute a representation and warranty by such
Holder that the information relating to such Holder and its plan of distribution is as set forth in
the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus
does not as of the time of such sale contain any untrue statement of a material fact relating to or
provided by such Holder or its plan of distribution and that such Prospectus does not as of the
time of such sale omit to state any material fact relating to or provided by such Holder or its
plan of distribution necessary to make the statements in such Prospectus, in the light of the
circumstances under which they were made, not misleading.

          SECTION 5. Registration Expenses. The Company shall bear all fees and expenses incurred in
connection with the performance by the Company of its obligations under Sections 2 and 3 of this
Agreement whether or not any Registration Statement is declared effective. Such fees and expenses
shall include, without limitation, (i) all registration and filing fees (including, without
limitation, fees and expenses (x) with respect to filings required to be made with the National
Association of Securities Dealers, Inc. and (y) of compliance with federal and state securities or
Blue Sky laws (including, without limitation, reasonable fees and disbursements of the Special
Counsel, if any, in connection with Blue Sky qualifications of the Registrable Securities under the
laws of such jurisdictions as Notice Holders of a majority of the Registrable Securities being sold
pursuant to a Registration Statement may designate)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities in a form eligible for
deposit with The Depository Trust Company), (iii) duplication expenses relating to copies of any
Registration Statement or Prospectus delivered to any Holders hereunder, (iv) fees and
disbursements of counsel for the Company in connection with any Registration Statement, (v)
reasonable fees and disbursements of the Trustee and its counsel and of the registrar and transfer
agent for the Common Stock and (vi) any Securities Act liability insurance obtained by the Company
in its sole discretion. In addition, the Company shall pay the internal expenses of the Company
(including, without limitation, all salaries and expenses of officers and employees performing
legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in
connection with the listing by the Company of the Registrable Securities on any securities exchange
on which similar securities of the Company are then listed and the fees and expenses of any person,
including special experts, retained by the Company. Notwithstanding the provisions of this Section
5, each seller of Registrable Securities shall pay selling expenses, including any underwriting
discount and commissions, all registration expenses to the extent required by applicable law and,
except as otherwise provided herein, fees and expenses of counsel to such seller.

          SECTION 6. Indemnification and Contribution.

     (a) Indemnification by the Company. Upon the registration of the Registrable Securities
pursuant to Section 2 hereof, the Company shall indemnify and hold harmless each Notice Holder and
each underwriter, selling agent or other securities professional, if any, which facilitates the
disposition of Registrable Securities, and each of their respective officers and directors and each
person who controls such Notice Holder, underwriter, selling agent or other securities professional
within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such
person being sometimes referred to as an “Indemnified Person”) against any losses, claims, damages
or liabilities, joint or several, to which such Indemnified Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of
a material fact contained in any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act, or any Prospectus contained therein or
furnished by the Company to any Indemnified Person, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not misleading, and the
Company hereby agrees to reimburse such Indemnified Person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any such action or

D-12

 

claim as such expenses are incurred; provided, however, that the Company shall not be liable
to any such Indemnified Person in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in such Shelf Registration Statement or Prospectus, or amendment
or supplement, in reliance upon and in conformity with written information furnished to the Company
by such Indemnified Person expressly for use therein.

     (b) Indemnification by the Notice Holders and any Agents and Underwriters. Each Notice Holder
agrees, as a consequence of the inclusion of any of such Notice Holder’s Registrable Securities in
such Shelf Registration Statement, and each underwriter, selling agent or other securities
professional, if any, which facilitates the disposition of Registrable Securities shall agree, as a
consequence of facilitating such disposition of Registrable Securities, severally and not jointly,
to (i) indemnify and hold harmless the Company, its directors, officers who sign any Shelf
Registration Statement and each person, if any, who controls the Company within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses,
claims, damages or liabilities to which the Company or such other persons may become subject, under
the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in such Shelf Registration Statement or Prospectus, or any amendment
or supplement, or arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the statements therein not
misleading, 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 written information furnished to the Company by such Notice Holder, underwriter,
selling agent or other securities professional expressly for use therein, and (ii) reimburse the
Company for any legal or other expenses reasonably incurred by the Company in connection with
investigating or defending any such action or claim as such expenses are incurred.

     (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against an indemnifying party under this Section 6, notify
such indemnifying party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to any indemnified
party otherwise than under the indemnification provisions of or contemplated by subsection (a) or
(b) above. In case any such action shall be brought against any indemnified party and it shall
notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled
to participate therein and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party (who shall not, except with the consent of the indemnified party, be counsel
to the indemnifying party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, such indemnifying party shall not be liable to
such indemnified party under this Section 6 for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying party shall, without
the written consent of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or claim in respect of
which indemnification or contribution may be sought hereunder (whether or not the indemnified party
is an actual or potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all liability arising
out of such action or claim and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act, by or on behalf of any indemnified party.

D-13

 

     (d) Contribution. If the indemnification provided for in this Section 6 is unavailable to or
insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of
any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein,
then each indemnifying party 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 the relative fault of the indemnifying party and the
indemnified party in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations including, but not limited to, the timeliness of the notice given as
required by Section 6(c). The relative fault of such indemnifying party and indemnified party
shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material fact relates to
information supplied by such indemnifying party or by such indemnified party, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata allocation (even if the
Notice Holders or any underwriters, selling agents or other securities professionals or all of them
were treated as one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 6(d). The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with investigating or
defending any such action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The obligations of the Notice Holders and
any underwriters, selling agents or other securities professionals in this Section 6(d) to
contribute shall be several in proportion to the percentage of principal amount of Registrable
Securities registered or underwritten, as the case may be, by them and not joint.

     (e) Notwithstanding any other provision of this Section 6, in no event will any (i) Notice
Holder be required to undertake liability to any person under this Section 6 for any amounts in
excess of the dollar amount of the proceeds to be received by such Holder from the sale of such
Holder’s Registrable Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Shelf Registration Statement under which such Registrable Securities are
to be registered under the Securities Act and (ii) underwriter, selling agent or other securities
professional be required to undertake liability to any person hereunder for any amounts in excess
of the discount, commission or other compensation payable to such underwriter, selling agent or
other securities professional with respect to the Registrable Securities underwritten by it and
distributed to the public.

     (f) The obligations of the Company under this Section 6 shall be in addition to any liability
which the Company may otherwise have to any Indemnified Person and the obligations of any
Indemnified Person under this Section 6 shall be in addition to any liability which such
Indemnified Person may otherwise have to the Company. The remedies provided in this Section 6 are
not exclusive and shall not limit any rights or remedies which may otherwise be available to an
indemnified party at law or in equity.

          SECTION 7. Information Requirements. The Company covenants that, if at any time before the
end of the Effectiveness Period the Company is not subject to the reporting requirements of the
Exchange Act, it will cooperate with any Holder and take such further reasonable action as any
Holder may reasonably request in writing (including, without limitation, making such reasonable
representations as any such Holder may reasonably request), all to the extent required from time to
time to enable such Holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144 and Rule 144A under the Securities
Act and customarily taken in

D-14

 

connection with sales pursuant to such exemptions. Upon the written request of any Holder,
the Company shall deliver to such Holder a written statement as to whether it has complied with
such filing requirements, unless such a statement has been included in the Company’s most recent
report filed pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding the
foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its
securities (other than the Common Stock) under any section of the Exchange Act.

          SECTION 8. Underwritten Registrations. The Holders of Registrable Securities covered by a
Shelf Registration Statement who desire to do so may sell such Registrable Securities to an
underwriter in an underwritten offering for reoffering to the public. If any of the Registrable
Securities covered by any Shelf Registration Statement are to be sold in an underwritten offering,
the investment banker or investment bankers and manager or managers that will administer the
offering will be selected by the Holders of a majority of such Registrable Securities included in
such offering, subject to the consent of the Company (which shall not be unreasonably withheld or
delayed), and such Holders shall be responsible for all underwriting commissions and discounts and
any transfer taxes in connection therewith. No person may participate in any underwritten
registration hereunder unless such person (i) agrees to sell such person’s Registrable Securities
on the basis reasonably provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers
of attorney, indemnities, underwriting agreements and other documents reasonably required under the
terms of such underwriting arrangements.

          SECTION 9. Miscellaneous.

     (a) No Conflicting Agreements. The Company is not, as of the date hereof, a party to, nor
shall it, on or after the date of this Agreement, enter into, any agreement with respect to its
securities that conflicts with the rights granted to the Holders in this Agreement. The Company
represents and warrants that the rights granted to the Holders hereunder do not in any way conflict
with the rights granted to the holders of the Company’s securities under any other agreements.

     (b) Amendments and Waivers. The provisions of this Agreement, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given, unless the Company has obtained the written consent of
Holders of a majority of Registrable Securities. Notwithstanding the foregoing, a waiver or
consent to depart from the provisions hereof with respect to a matter that relates exclusively to
the rights of Holders whose securities are being sold pursuant to a Registration Statement and that
does not directly or indirectly affect the rights of other Holders may be given by Holders of at
least a majority of the Registrable Securities being sold by such Holders pursuant to such
Registration Statement; provided that the provisions of this sentence may not be amended, modified
or supplemented except in accordance with the provisions of the immediately preceding sentence.
Notwithstanding the foregoing, this Agreement may be amended by written agreement signed by the
Company and the Initial Purchaser, without the consent of the Holders of Registrable Securities, to
cure any ambiguity or to correct or supplement any provision contained herein that may be defective
or inconsistent with any other provision contained herein, or to make such other provisions in
regard to matters or questions arising under this Agreement that shall not adversely affect the
interests of the Holders of Registrable Securities. Each Holder of Registrable Securities
outstanding at the time of any such amendment, modification, supplement, waiver or consent or
thereafter shall be bound by any such amendment, modification, supplement, waiver or consent
effected pursuant to this Section 9(b), whether or not any notice, writing or marking indicating
such amendment, modification, supplement, waiver or consent appears on the Registrable Securities
or is delivered to such Holder.

D-15

 

     (c) Notices. All notices and other communications provided for or permitted hereunder shall

     (d) Approval of Holders. Whenever the consent or approval of Holders of a specified
percentage of Registrable Securities is required hereunder, Registrable Securities held by the
Company or its affiliates (as such term is defined in Rule 405 under the Securities Act) (other
than the Initial Purchaser or subsequent Holders if such subsequent Holders are deemed to be such
affiliates solely by reason of

D-16

 

their holdings of such Registrable Securities) shall not be counted in determining whether
such consent or approval was given by the Holders of such required percentage.

     (e) Successors and Assigns. Any person who purchases any Registrable Securities from the
Initial Purchaser shall be deemed, for purposes of this Agreement, to be an assignee of the Initial
Purchaser. This Agreement shall inure to the benefit of and be binding upon the successors and
assigns of each of the parties and shall inure to the benefit of and be binding upon each Holder of
any Registrable Securities, provided that nothing herein shall be deemed to permit any assignment,
transfer or other disposition of Registrable Securities in violation of the terms of the Indenture.
If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by
operation of law or otherwise, such Registrable Securities shall be held subject to all of the

to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants
and restrictions set forth herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby, and the parties hereto shall use their reasonable best
efforts to find and employ an alternative means to achieve the same or substantially the same
result as that contemplated by such term, provision, covenant or restriction, it being intended
that all of the rights and privileges of the parties shall be enforceable to the fullest extent
permitted by law.

     (j) Entire Agreement. This Agreement is intended by the parties as a final expression of
their agreement and is intended to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained herein and the
registration rights granted by the Company with respect to the Registrable Securities. Except as
provided in the Purchase Agreement, the Indenture and the Notes, there are no restrictions,

Securities. This Agreement supersedes all prior agreements and undertakings among the parties with
