    B.           The
Company has requested that the Administrative Agent and the Lenders further
amend the Credit Agreement to reflect certain changes thereto and to grant a
limited waiver with respect to the Credit Agreement.

     

    C.           The
Administrative Agent and the undersigned Lenders are willing to amend the Credit
Agreement and to grant a limited waiver on the terms and conditions set forth
below.

     

    Now,
therefore, in consideration of the mutual execution hereof and other good and
valuable consideration, the parties hereto agree as follows:

     

    1.           Reduction of Aggregate
Commitments.  Notwithstanding the terms and provisions of
Amendment No. 6, the aggregate amount of the Lenders' Commitments shall be
reduced to $85,000,000 commencing on March 1, 2009 and to $80,000,000 commencing
on July 1, 2009.  Accordingly, Schedule 2.01 of the Credit Agreement
is hereby amended and restated as set forth on Annex I
hereto.

     

    2.           Limited
Waiver.  Upon satisfaction of the conditions to effectiveness
set forth in paragraph 5 below, the Administrative Agent and the Lenders
signatory hereto hereby waive the requirement that the Company comply with the
financial covenant set forth in Section 6.09 of the Credit Agreement for the
fiscal periods ending on or about December 31, 2008 and January 31, 2009,
respectively, and with the financial covenant set forth in Section 6.12 of the
Credit Agreement for the fiscal period ending on or about December 31, 2008,
provided such waivers shall expire at 5 p.m. on February 28, 2009, at which time
the terms and provisions of Sections 6.09 and 6.12 of the Credit Agreement shall
be effective with the same force and effect under the Credit Agreement as if
such waivers had not been given.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    3.           Ratification.  The
Company hereby ratifies and confirms its undertakings set forth in paragraph
4(b) of Amendment No. 6 and acknowledges that any breach thereof shall
constitute an Event of Default under the Credit Agreement.

     

    4.           Representations and
Warranties of the Company.  The Company represents and warrants
that:

     

    (a)           The
execution, delivery and performance by the Company of this Seventh Amendment has
been duly authorized by all necessary corporate action and this Seventh
Amendment is a legal, valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, except as the enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar law affecting creditors’
rights generally and (ii) general principles of equity, regardless of whether
considered in a proceeding in equity or at law.

     

    (b)           Each
of the representations and warranties contained in the Credit Agreement and the
other Credit Documents is true and correct in all material respects on and as of
the date hereof as if made on the date hereof (except any such representation or
warranty that expressly relates to or is made expressly as of a specific earlier
date, in which case such representation or warranty shall be true and correct
with respect to or as of such specific earlier date).

     

    (c)           After
giving effect to this Seventh Amendment, no Default has occurred and is
continuing.

     

    5.           Effective
Date.  This Seventh Amendment shall become effective upon
receipt by the Administrative Agent of (i) duly executed counterparts of this
Seventh Amendment from the Company, Select Comfort Retail Corporation and the
Lenders, (ii) the Reaffirmation of Guaranty in the form attached hereto as Exhibit A executed by
each of the Subsidiary Guarantors, and (iii) payment of all fees and
out-of-pocket costs and expenses of its counsel and the financial advisor
retained by its counsel invoiced through the date hereof.

     

    6.           Reference to and Effect Upon
the Credit Agreement.

     

    (a)           Except
as specifically amended above, the Credit Agreement and the other Credit
Documents shall remain in full force and effect and are hereby ratified and
confirmed.

     

    (b)           The
execution, delivery and effectiveness of this Seventh Amendment shall not
operate as a waiver of any right, power or remedy of the Administrative Agent or
any Lender under the Credit Agreement or any Credit Document, nor constitute a
waiver of any provision of the Credit Agreement or any Credit Document, except
as specifically set forth herein.  Upon the effectiveness of this
Seventh Amendment, each reference in the Credit Agreement to “this Agreement”,
“hereunder”, “hereof”, “herein” or words of similar import shall mean and be a
reference to the Credit Agreement as amended hereby.

proved by the affidavit of a witness to such execution or by the certificate of any notary public
or other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by an officer of a corporation or a member of a partnership, on behalf of such corporation or
partnership, such certificate or affidavit shall also constitute sufficient proof of his authority.
The fact and date of the execution of any such instrument or writing, or the authority of the
person executing the same, may also be proved in any other manner which the Trustee deems
sufficient.

     (c) The ownership of Securities shall for all purposes be determined by reference to the
Security Register, as such register shall exist as of the applicable date.

     (d) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other action, the Company may, at its option, by Board
Resolution, fix in advance a Record Date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other action, but the Company
shall have no obligation to do so. If such Record Date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given before or after such
Record Date, but only the Holders of record at the close of business on such Record Date shall be
deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that purpose the
Outstanding Securities shall be computed as of such Record Date. Promptly and in any case not later
than ten (10) days after setting a Record Date, the Company shall notify the Trustee and the
Holders of such Record Date.

     (e) Any request, demand, authorization, direction, notice, consent, waiver or other action by
the Holder of any Security shall bind each subsequent Holder of such Security, and each Holder of

thereof, with respect to anything done or suffered to be done by the Trustee or the Company in
reliance upon such action, whether or not notation of such action is made upon such Security.

     Section 1.05. Notices, etc., to Trustee and Company. Any request, order, authorization,
direction, consent, waiver, or other action to be taken by the Trustee, the Company, or the Holders
hereunder (including any Company Order), and any notice to be given to the Trustee or the Company
with respect to any action taken or to be taken by the Trustee, the Company, or the Holders
hereunder, shall be sufficient if made in writing and

     (a) (if to be furnished or delivered to or filed with the Trustee by the Company or any
Holder) delivered to the Trustee at its Corporate Trust Office, or

     (b) (if to be furnished or delivered to the Company by the Trustee or any Holder, and except

specified in the Security carrying the right to repayment) mailed to the Company, first-class

Financial Officer, or at any other address hereafter furnished in writing by the Company to the
Trustee.

     Section 1.06. Notice To Holders; Waiver. Where this Indenture or any Security provides for
notice to Holders of any event, such notice shall be sufficiently given (unless otherwise expressly
provided herein or in such Security) if in writing and mailed, first-class postage prepaid, to each
Holder affected by such event, at his or her address as it appears in the Security Register as of
the applicable Record Date, not later than the latest date or earlier than the earliest date
prescribed by this Indenture or such Security for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice nor any defect in any
notice so mailed to any particular Holder shall affect the sufficiency of such notice with respect
to other Holders. Where this Indenture or any Security provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice, either before or
after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.

     In case, by reason of the suspension of regular mail service as a result of a strike, work
stoppage or otherwise, it shall be impractical to mail notice of any event to any Holder when such
notice is required to be given pursuant to any provision of this Indenture or the applicable
Security, then any method of notification as shall be reasonably satisfactory to the Trustee and
the Company shall be deemed to be sufficient for the giving of such notice.

     Section 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or
conflicts with another provision hereof which is required to be included in this Indenture by any
of the provisions of the TIA, such required provision shall control.

herein and the Table of Contents hereof are for convenience only and shall not affect the
construction of any provision of this Indenture.

     Section 1.09. Successors and Assigns. All covenants and agreements in this Indenture by the
Company shall bind its successors and assigns, whether so expressed or not.

     Section 1.10. Separability Clause. In case any provision in this Indenture or in the
Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

     Section 1.11. Benefits Of Indenture. Nothing in this Indenture or in any Securities, express
or implied, shall give to any Person, other than the parties hereto, their successors hereunder,
the Authenticating Agent, the Security Registrar, any Paying Agent, and the Holders of Securities
(or such of them as may be affected thereby), any benefit or any legal or equitable right, remedy
or claim under this Indenture.

     Section 1.12. Governing Law. This Indenture shall be governed by and construed in accordance
with the laws of the State of New York.

15

 

     Section 1.13. Counterparts. This instrument may be executed in any number of counterparts,
each of which when so executed shall be deemed to be an original, but all of which shall together
constitute but one and the same instrument.

     Section 1.14. Judgment Currency. The Company agrees, to the fullest extent that it may
effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any
court, with respect to the Securities, it is necessary to convert the sum due in respect of the
principal, premium, if any, or interest, if any, payable with respect to such Securities into a
currency in which a judgment can be rendered (the “Judgment Currency”), the rate of exchange from

exchange dealers in the City of New York for the purchase of the aggregate amount of the judgment
(as denominated in the Judgment Currency) on the New York Business Day preceding the date on which
a final unappealable judgment is rendered, for settlement on such payment date, and at which the
applicable dealer timely commits to execute a contract, and (b) the Company’s obligations under
this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied
by any tender, or by any recovery pursuant to any judgment (whether or not entered in accordance
with the preceding clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt by the judgment creditor of
the full amount of the Required Currency expressed to be payable in respect of such payments, (ii)
shall be enforceable as an alternative or additional cause of action for the purpose of recovering
in the Required Currency the amount, if any, by which such actual receipt shall fall short of the
full amount of the Required Currency so expressed to be payable, and (iii) shall not be affected by
judgment being obtained for any other sum due under this Indenture.

     Section 1.15. Legal Holidays. In any case where any Interest Payment Date or Maturity of any
Security or the last day on which a Holder of a Security has a right to convert his Security shall
not be a New York Business Day at any Place of Payment or Place of Conversion, as the case may be,
then (notwithstanding any other provision of this Indenture or of the Securities) payment of
interest or principal (and premium, if any) need not be made at such Place of Payment or Place of
Conversion, as the case may be, on such date, but may be made on the next succeeding New York
Business Day at such Place of Payment or Place of Conversion, as the case may be, with the same
force and effect as if made on the Interest Payment Date, at Maturity, or by such last day for
conversion; provided that no interest shall accrue for the period from and after such Interest
Payment Date, Maturity, or last day for conversion, as the case may be.

     Section 1.16. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY

directly or indirectly, forces beyond its reasonable control, including, without limitation,

authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of
other Securities pursuant the terms of this Indenture.

     All Securities issued under this Indenture shall in all respects be equally and ratably
entitled to the benefits hereof, without preference, priority, or distinction on account of the
actual time of the authentication and delivery thereof.

     The principal of, premium, if any, and interest, if any, on the Securities shall be payable as
provided in the form of Security.

     Section 2.06. Denominations. The Securities shall be issuable only in registered form,
without interest coupons, in minimum denominations of U.S.$2,000 and any integral multiple of
U.S.$1,000.

     Section 2.07. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its President and Chief Executive
Officer or its Senior Vice President and Chief Financial Officer. Any such signature may be manual
or facsimile.

     Securities bearing the manual or facsimile signature of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities to the Trustee for authentication, together with an order for
authentication and delivery (an “Authentication Order”) with respect to such Securities, and the
Trustee shall, upon receipt of such Authentication Order, and an Officer’s Certificate and Opinion
of Counsel in the form described in Section 1.02, in accordance with procedures reasonably

18

 

acceptable to the Trustee set forth in the Authentication Order, and subject to the provisions
hereof, authenticate and deliver such Securities to such recipients as may be specified from time
to time pursuant to such Authentication Order.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for in Section 2.04 executed by the Trustee by manual signature of an
authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the
only evidence, that such Security has been duly authenticated and delivered hereunder.

     Section 2.08. Reserved.

     Section 2.09. Registration, Registration of Transfer and Exchange.

     (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 8.02 being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities. The Trustee is
hereby appointed Security Registrar for the purpose of registering Registered Securities and
transfers and exchanges of Registered Securities as herein provided.

     Upon surrender for registration of transfer of any Security at an office or agency of the
Company designated pursuant to Section 8.02 for such purpose, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee or transferees,
one or more new Securities of authorized denominations and of a like aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.

     At the option of the Holder, and subject to the other provisions of this Section 2.09,
Securities may be exchanged for other Securities of authorized denomination and of a like aggregate
principal amount, upon surrender of the Securities to be exchanged at any such office or agency.
Whenever any Securities are so surrendered for exchange, and subject to the other provisions of
this Section 2.09, the Company shall execute, and the Trustee shall authenticate and make available
for delivery, the Securities the Holder making the exchange is entitled to receive. Every Security
presented or surrendered for registration of transfer or for exchange shall (if so required by the
Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing.

     All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company, evidencing the same debt, subject to the other provisions of this
Section 2.09, and entitled to the same benefits under this Indenture, as the Securities surrendered
upon such registration of transfer or exchange.

     Unless otherwise provided in the Security to be transferred or exchanged, no service charge
shall be made to a Holder for any registration of transfer or exchange of Securities except as
provided in Section 2.10, but the Company may (unless otherwise provided in such Security) require
payment of a sum sufficient to cover any tax or other governmental charge that may be

19

 

imposed in connection with any registration of transfer or exchange of Securities, other than
exchanges pursuant to this Section 2.09 or Section 9.02 (other than where the shares of Common
Stock are to be issued or delivered in a name other than that of the Holder of the Security) not
involving any transfer and other than any stamp and other duties, if any, that may be imposed in
connection with any such transfer or exchange by the United States or any political subdivision
thereof or therein, which shall be paid by the Company.

     (b) Neither the Trustee, the Paying Agent nor any of their agents shall (1) have any duty to
monitor compliance with or with respect to any federal or state or other securities or tax laws or
(2) have any duty to obtain documentation on any transfers or exchanges other than as specifically
required hereunder.

     Section 2.10. Mutilated, Destroyed, Lost or Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute and the
Trustee shall authenticate and make available for delivery in exchange therefor a new Security of
like tenor and principal amount and bearing a number not contemporaneously outstanding.

     If there be delivered to the Company and to the Trustee:

     (a) evidence to their satisfaction of the destruction, loss or theft of any Security, and

     (b) such security or indemnity as may be satisfactory to the Company and the Trustee to save
each of them and any agent of either of them harmless,

then, in the absence of actual notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and
make available for delivery, in lieu of any such destroyed, lost or stolen Security, a new Security
of like tenor and principal amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion, but subject to any conversion rights, may,
instead of issuing a new Security, pay such Security, upon satisfaction of the conditions set forth
in the preceding paragraph.

     Upon the issuance of any new Security under this Section 2.10, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto (other than any stamp and other duties, if any, that may be imposed in connection
therewith by the United States or any political subdivision thereof or therein, which shall be paid
by the Company) and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

     Every new Security issued pursuant to this Section 2.10 in lieu of any mutilated, destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and such new Security shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities duly issued hereunder.

20

 

     The provisions of this Section 2.10 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies of any Holder with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities.

     Section 2.11. Payment of Interest; Interest Rights Preserved.

     Interest on any Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular Record Date for such
interest.

     Any interest on any Security that is payable, but is not punctually paid or duly provided for,
on any Interest Payment Date (“Defaulted Interest”) shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b)
below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Securities (or their respective Predecessor Securities) are registered at the close of
business on a special record date (the “Special Record Date”) for the payment of such Defaulted
Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in
writing of the amount of Defaulted Interest proposed to be paid on each Security, the date of the
proposed payment and the Special Record Date, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit 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 provided in this clause. The Special Record
Date for the payment of such Defaulted Interest 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 fifteen (15)
days after the receipt by the Trustee of the notice of the proposed payment. The Trustee, 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 such Holder’s address as it appears in the Security 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 Securities (or their respective Predecessor Securities)
are registered at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (b).

     (b) The Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, if, after written notice given by
the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment
shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 2.11 and Section 2.09, each Security
delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to accrue, that were
carried by such other Security.

21

 

     Interest on any Security that is converted in accordance with Section 9.02 during a Record
Date Period shall be payable in accordance with the provisions of Section 9.02.

     Section 2.12. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 2.11) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.

     Section 2.13. Cancellation. All Securities surrendered for payment, repurchase, redemption,
registration of transfer or exchange or conversion shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall, at the
written request of the Company, be cancelled promptly by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled in accordance with this
Section. The Trustee shall dispose of all cancelled Securities in accordance with applicable law
and its customary practices in effect from time to time.

     Section 2.14. Computation of Interest. Interest on the Securities shall be computed on the
basis of a 360-day year of twelve (12) 30-day months.

     Section 2.15. CUSIP Numbers. The Company in issuing Securities may, at the Company’s sole
determination, obtain and use “CUSIP” numbers (if then generally in use) in addition to serial
numbers and the Trustee may use such CUSIP numbers in addition to serial numbers in notices of
repurchase as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such CUSIP numbers either as printed on the
Securities or as contained in any notice of a repurchase or redemption and that reliance may be
placed only on the serial or other identification numbers printed on the Securities, and any such
repurchase or redemption shall not be affected by any defect in or omission of such CUSIP numbers.
The Company shall promptly notify the Trustee in writing of any change in any such CUSIP number.

ARTICLE 3

Satisfaction and Discharge

     Section 3.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of
further effect with respect to the Securities (except as to any surviving rights of conversion or
transfer or exchange of Securities expressly provided for herein or in the form of Security), and
the Trustee, on demand of and at the expense of the Company, shall execute proper instruments, in
form and substance reasonably satisfactory to the Trustee, acknowledging satisfaction and discharge
of this Indenture, when

     (a) either

     (i) all Securities theretofore authenticated and delivered (other than (A) Securities
which have been destroyed, lost, or stolen and which have been replaced or paid as provided
in Section 2.09, and (B) Securities for whose payment money has

22

 

theretofore been deposited in trust or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust, as provided in Section
8.03) have been delivered to the Trustee canceled or for cancellation; or

     (ii) all such Securities not theretofore delivered to the Trustee canceled or for
cancellation

     (A) have become due and payable, or

     (B) will, in accordance with their Scheduled Maturity Date, become due and
payable within one year,

and, in any of the cases described in subparagraphs (A) or (B) above, the Company has irrevocably
deposited or caused to be deposited with the Trustee, as trust funds in trust for the purpose, (x)
an amount in money sufficient, (y) U.S. Government Obligations or Equivalent Government Securities
which through the payment of interest and principal in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment, money sufficient, or
(z) a combination of (x) and (y) sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the
Trustee, to pay and discharge the entire indebtedness on the Securities with respect to principal,
premium, if any, and interest, if any, to the date of such deposit (in the case of Securities which
have become due and payable), or to the Scheduled Maturity Date; provided, however, that if such
U.S. Government Obligations or Equivalent Government Securities are callable or redeemable at the
option of the issuer thereof, the amount of such money, U.S. Government Obligations and Equivalent
Government Securities deposited with the Trustee must be sufficient to pay and discharge the entire
indebtedness referred to above if such issuer elects to exercise such call or redemption provisions
at any time prior to the Scheduled Maturity Date. The Company, but not the Trustee, shall be
responsible for monitoring any such call or redemption provision; and

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

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

     Notwithstanding the satisfaction and discharge of this Indenture with respect to the
Securities, the obligations of the Company under paragraph (a) of this Section 3.01 and its
obligations to the Trustee under Section 5.07 shall survive, and the obligations of the Trustee
under Sections 3.02, 3.04 and 8.03 shall survive.

     Section 3.02. Application of Trust Money; Excess Funds. All money and U.S. Government
Obligations or Equivalent Government Securities (including the proceeds thereof) deposited with the
Trustee pursuant to Section 3.01 hereof shall be held in trust and applied by it, in accordance
with the provisions of this Indenture and the Securities in respect of which it was deposited, to
the payment, either directly or through any Paying Agent (including the Company acting as its own
Paying Agent), as the Trustee may determine, to the Persons entitled thereto, of the principal,
premium, if any, and interest, if any, for whose payment such money has been

23

 

deposited with the Trustee; but such money need not be segregated from other funds except to
the extent required by law.

     The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or U.S. Government Obligations or Equivalent Government Securities
deposited pursuant to Section 3.01 hereof or the principal and interest received in respect thereof
other than any such tax, fee or other charge which by law is for the account of the Holders of the
Outstanding Securities.

     Anything in this Article 3 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon Company Order any money or U.S. Governmental Obligations or
Equivalent Government Securities held by it as provided in Section 3.01 which, in the opinion of a
nationally recognized investment bank, appraisal firm or firm of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the
Trustee, (which may be the opinion delivered under Section 3.01), are in excess of the amount
thereof that would then be required to be deposited to effect an equivalent satisfaction and
discharge.

     Section 3.03. Paying Agent to Repay Moneys Held. Upon the satisfaction and discharge of this
Indenture, all moneys then held by any Paying Agent of the Securities (other than the Trustee)
shall, upon demand 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 moneys.

     Section 3.04. Return of Unclaimed Amounts. Any amounts deposited with or paid to the Trustee
or any Paying Agent or then held by the Company, in trust for payment of the principal of, premium,
if any, or interest, if any, on the Securities not applied but remaining unclaimed by the Holders
of such Securities for two years after the date upon which the principal of, premium, if any, or
interest, if any, on such Securities, as the case may be, shall have become due and payable, shall
be repaid to the Company by the Trustee on Company Order or (if then held by the Company) shall be
discharged from such trust; and the Holder of any of such Securities shall thereafter look only to
the Company for any payment which such Holder may be entitled to collect (until such time as such
unclaimed amounts shall escheat, if at all, to the State of New York) and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease. Notwithstanding the foregoing, the Trustee or Paying
Agent, before being required to make any such repayment, may at the expense of the Company cause to
be published once a week for two successive weeks (in each case on any day of the week) in a
newspaper printed in the English language and customarily published at least once a day at least
five days in each calendar week and of general circulation in the Borough of Manhattan, in the City
and State of New York, a notice that said amounts have not been so applied and that after a date
named therein any unclaimed balance of said amounts then remaining will be promptly returned to the
Company.

ARTICLE 4

Remedies

     Section 4.01. Events of Default. “Event of Default”, wherever used herein, means with respect
to the Securities any one of the following events (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):

24

 

     (a) default in the payment of any interest on any Security when it becomes due and payable,
and continuance of such default for a period of 30 days; or

     (b) default in the payment of the principal amount of (or premium, if any, on) any Security as
and when the same shall become due, either at Stated Maturity, upon redemption, by declaration, or
otherwise; or

     (c) default in the performance, or breach, of any covenant of the Company or any Subsidiary in
this Indenture in respect of the Securities (other than a covenant or warranty in respect of the
Securities a default in the performance or breach of which is specifically dealt with elsewhere in
this Section 4.01), and continuance of such default or breach for a period of ninety (90) days
after there has been given, by registered or certified mail, to the Company by the Trustee or to
the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities, a written notice specifying such default or breach and requiring it to be
remedied and stating that such notice is a “Notice of Default” hereunder; or

     (d) default in the payment when due of the principal of any indebtedness under any bond,
debenture, note or other evidence of indebtedness for money borrowed by the Company or any
Significant Subsidiary, if any, in excess of U.S.$2,000,000, whether such indebtedness now exists
or shall hereafter be created, if the indebtedness is not discharged and such default continues for
a period of thirty (30) days or more, or if such indebtedness has been accelerated, such
acceleration is not annulled, within a period of thirty (30) days after there shall have been
given, by registered or certified mail, to the Company by the Trustee or to the Company and the
Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Securities,
a written notice specifying such default and requiring the Company to cause such indebtedness to be
discharged or such acceleration to be rescinded or annulled and stating that such notice is a
“Notice of Default” hereunder;

     (e) the entry by a court having jurisdiction in the premises of (1) a decree or order for
relief in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding
under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law
or (2) a decree or order adjudging the Company or any Significant Subsidiary a bankrupt or
insolvent, or approving as properly filed a petition seeking reorganization, arrangement,
adjustment or composition of or in respect of the Company or any Significant Subsidiary under any
applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee,
trustee, sequestrator or other similar official of the Company or any Significant Subsidiary or of
any substantial part of its property, or ordering the winding up or liquidation of its affairs, 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 90 consecutive days; or

     (f) the commencement by the Company or any Significant Subsidiary 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 a bankrupt or insolvent, or the
consent by it to the entry of a decree or order for relief in respect of the Company or any
Significant Subsidiary 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 it, or the filing by it of a petition or answer
or consent seeking reorganization or similar relief under any applicable federal or state law, or
the consent by it to the filing of such petition or to the appointment of or taking possession by a
custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the

25

 

Company or any Significant Subsidiary or of any substantial part of its property, or the
making by it of an assignment for the benefit of creditors, or the admission by it in writing of
its inability to pay its debts generally as they become due, or the taking of corporate action by
the Company or any Significant Subsidiary in furtherance of any such action.

     A default under any indebtedness of the Company other than the Securities will not constitute
an Event of Default under this Indenture.

     Section 4.02. Acceleration of Maturity; Rescission, and Annulment. If any Event of Default
described in Section 4.01 above (other than an Event of Default described in Section 4.01(e) and
Section 4.01(f)) shall have occurred and be continuing, with respect to any Securities then and in
each and every such case, unless the aggregate principal amount of all the Securities have already
become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal
amount of the Outstanding Securities, by notice in writing to the Company (and to the Trustee if
given by Holders), may declare the principal amount of all the Securities and any and all accrued
interest thereon to be due and payable immediately, and upon any such declaration the same shall
become and shall be immediately due and payable, any provision of this Indenture or the Securities
to the contrary notwithstanding. If an Event of Default specified in Section 4.01(e) or Section
4.01(f) occurs, the principal amount of the Outstanding Securities and the Make-Whole Payment shall
immediately become and be due and payable without any declaration or other act on the part of the
Trustee or any Holder.

     If an Event of Default occurs, the outstanding Securities shall bear interest from the date of
the event that creates the Event of Default until such Event of Default is cured, at the rate of
the lesser of (i) twenty-one percent (21%) per annum or (ii) the maximum rate permitted by
applicable law, regardless of when or whether the Holders deliver a Notice of Default or any Holder
or the Trustee declares the outstanding principal balance due and payable as provided in this
Section 4.02.

     At any time after such a declaration of acceleration has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by
written notice to the Company and the Trustee, may rescind and annul such declaration and its
consequences if all Events of Default with respect to the Securities, other than the nonpayment of
the principal of the Securities which have become due solely by such acceleration, have been cured
or waived as provided in Section 4.13, if such cure or waiver does not conflict with any judgment
or decree set forth in Section 4.01(e) and Section 4.01(f) and if all sums paid or advanced by the
Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel have been paid.

     No such rescission shall affect any subsequent default or impair any right consequent thereon.

     Section 4.03. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company
covenants that if:

     (a) default is made in the payment of any installment of interest on any Security when such
interest becomes due and payable, or

26

 

     (b) default is made in the payment of the principal of (or premium, if any, on) any Security
at the Maturity thereof,

then, with respect to the Securities, the Company will, upon demand of the Trustee, pay to it, for
the benefit of the Holder of any such Security, the whole amount then due and payable on any such
Security for principal (and premium, if any) and interest, if any, with interest (to the extent
that payment of such interest shall be legally enforceable) upon the overdue principal (and
premium, if any) and upon overdue installments of interest, if any, at such rate or rates as may be
prescribed therefor by the terms of any such Security; and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel and all other amounts due the Trustee under Section 5.07.

     If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or any other obligor upon the Securities and collect the money
adjudged or decreed to be payable in the manner provided by law out of the property of the Company
or any other obligor upon such Securities, wherever situated.

     If an Event of Default with respect to the Securities occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights of the Holders of
Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

     Section 4.04. Trustee May File Proofs of Claim. In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition, or other
judicial proceeding relative to the Company or any other obligor upon the Securities or the
property of the Company or of such other obligor or their creditors, the Trustee (irrespective of
whether the principal of the Securities 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 on the
Company for the payment of overdue principal or interest) shall be entitled and empowered, by
intervention in such proceedings or otherwise,

     (a) to file and prove a claim for the whole amount of principal, premium, if any, and
interest, if any, owing and unpaid in respect of the Securities, and to file such other papers or
documents as may be necessary and advisable in order to have the claims of the Trustee (including
any claim for the reasonable compensation, expenses, disbursements, and advances of the Trustee,
its agents and counsel, and all other amounts due the Trustee under Section 5.07) and of the
Holders allowed in such judicial proceedings, and

     (b) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; and any receiver, assignee, trustee, liquidator, sequestrator
(or other similar official) in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee and its agent and
counsel, and any other amounts due the Trustee under Section 5.07 hereof.

27

 

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

     Section 4.05. Trustee May Enforce Claims Without Possession of Securities. All rights of
action and claims under this Indenture or the Securities may be prosecuted and enforced by the
Trustee without the possession of any of the Securities or the production thereof in any proceeding
relating thereto, and any such 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 and its
agents and counsel, be for the ratable benefit of the Holders of the Securities, in respect of
which Securities such judgment has been recovered.

     Section 4.06. Application of Money Collected. Any money collected by the Trustee with respect
to Securities pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on account of principal,

of 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 5.07 hereof.

     Second: To the payment of the amounts then due and unpaid upon the Securities for principal,
premium, if any, interest, if any, and additional amounts, if any, in respect of which or for the
benefit of which such money has been collected, ratably, without preference or priority of any
kind.

     Section 4.07. Limitation on Suits. No Holder of any Security shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

     (a) such Holder has previously given written notice to the Trustee of a continuing Event of
Default with respect to the Securities;

     (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute proceedings in respect of
such Event of Default in its own name as Trustee hereunder;

     (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs,
expenses and liabilities to be incurred in compliance with such request;

     (d) the Trustee for 60 days after its receipt of such notice, request, and offer of indemnity
has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities;
it being understood and intended that no one or more Holders of Securities shall have any right in
any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other Holders of Securities (it being understood that the
Trustee does not have an affirmative duty to ascertain whether or not such actions or

28

 

forbearances are prejudicial to such Holders), or to obtain or to seek to obtain priority or
preference over any other such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and proportionate benefit of all the Holders of all
Securities.

     Section 4.08. Unconditional Right of Holders to Receive Principal, Premium, and Interest and
to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security
shall have the right, which is absolute and unconditional, to receive payment of the principal,
premium, if any, and (subject to Section 2.11) interest, if any on such Security on or after the
respective payment dates expressed in such Security and to convert such Security in accordance with
Article 9, and to institute suit for the enforcement of any such payment on or after such
respective date, and such right shall not be impaired or affected without the consent of such
Holder.

     Section 4.09. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted
any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, then and in every such case the Company, the Trustee and
the Holders shall, subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been instituted.

     Section 4.10. Rights and Remedies Cumulative. No right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy,
and every right or remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy.

     Section 4.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to
the Holders may be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

     Section 4.12. Control by Holders. The Holders of a majority in aggregate principal amount of
the Outstanding Securities shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee with respect to the Securities; provided that

     (a) the Trustee shall have the right to decline to follow any such direction if the Trustee,
being advised by counsel, determines that the action so directed may not lawfully be taken or would
conflict with this Indenture or if the Trustee in good faith shall, by a Responsible Officer,
determine that the proceedings so directed would involve it in personal liability or be unjustly
prejudicial to the Holders not taking part in such direction, and

     (b) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

29

 

     Section 4.13. Waiver of Past Defaults. The Holders of not less than a majority in principal
amount of the Outstanding Securities may, on behalf of the Holders of all the Securities, waive any
past default hereunder and its consequences, except a default not theretofore cured:

     (a) in the payment of principal, premium, if any, or interest, if any, on any Security, or

     (b) in respect of a covenant or provision in this Indenture which, under Article 7 hereof,
cannot be modified or amended without the consent of the Holder of each Outstanding Security.

     Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

     Section 4.14. Undertaking for Costs. All parties to this Indenture agree, and each Holder of
any Security 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, 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; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder of any Security or group of
Holders holding in the aggregate more than 10% in principal amount of the Outstanding Securities to
which the suit relates, or to any suit instituted by any Holder for the enforcement of the payment
of principal, premium, if any, or interest, if any, on any Security on or after the respective
payment dates expressed in such Security or for the enforcement of the right to convert any
Security in accordance with Article 9.

     Section 4.15. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law (other than any bankruptcy
law) wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it will not 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.

or opinions which by any provision hereof are specifically required to be furnished to the

however, that, except in the case of a default in the payment of the principal, premium, if any, or

31

 

directors and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders of Securities and; provided, further,

incurred by it in compliance with such request or direction;

     (f) the Trustee shall not be bound to make any investigation into the facts or matters stated

Indenture;

     (k) 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 each agent, custodian and
other Person employed to act hereunder (including, but not limited to, in its capacity as
Conversion Agent); and

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

     Section 5.04. Not Responsible for Recitals or Issuance of Securities. The recitals contained
herein and in the Securities, except the certificates of authentication, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their correctness. The

     (a) to pay the Trustee from time to time, and the Trustee shall be entitled to, such
compensation as the Company and the Trustee shall from time to time agree in writing 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);

33

 

     (b) 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
accordance with any provision of this Indenture (including the reasonable compensation and the
reasonable expenses and disbursements of its agents and counsel), except any such expense,

including the costs and expenses of defending itself against any claim (whether asserted by the
Company, or any Holder or any other Person) or liability in connection with the exercise or

collected by it as such for any amount owing to it or any predecessor Trustee pursuant to this
Section 5.07, except with respect to funds held in trust for the benefit of the Holders of
particular Securities.

     The provisions of this Section shall survive the satisfaction and discharge of this Indenture
and the termination or resignation of the Trustee.

     Section 5.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire
any conflicting interest within the meaning of the Trust Indenture Act, it shall either eliminate
such interest or resign as Trustee with respect to the Securities, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

     Section 5.09. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee
hereunder with respect to the Securities that shall be a corporation organized and doing business
under the laws of the United States of America or of any State or Territory thereof or of the
District of Columbia, authorized under such laws to exercise corporate trust powers, having a
combined capital and surplus of at least U.S.$50,000,000, and subject to supervision or examination
by federal or state authority and having its principal office and place of business in the City of
New York, if there be such a corporation having its principal office and place of business in said
City and willing to act as Trustee on customary and usual terms. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee with respect to the
Securities shall cease to be eligible in accordance with the provisions of this

34

 

Section, it shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

     Section 5.10. Resignation and Removal; Appointment of Successor. (a) No resignation or
removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Trustee under Section 5.11.

     (b) The Trustee may resign with respect to the Securities at any time by giving at least 60
days’ written notice thereof to 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
resignation, the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     (c) The Trustee may be removed with respect to the Securities at any time by Act of the
Holders of a majority in principal amount of the Outstanding Securities, delivered to the Trustee
and to the Company.

     (d) If at any time:

     (i) the Trustee shall fail to comply with Section 5.08 with respect to the Securities
after written request therefor by the Company or by any Holder who has been a bona fide
Holder of a Security for at least 6 months, or

     (ii) the Trustee shall cease to be eligible under Section 5.09 with respect to the
Securities and shall fail to resign after written request therefor by the Company or by any
such Holder, or

     (iii) the Trustee shall become incapable of acting, or shall be adjudged 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, subject to
Section 4.14, any Holder who has been a bona fide Holder of a Security for at least 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 with respect to the Securities or, in the case of this clause (iii), with respect
to the Securities.

     (e) If the Trustee shall resign, be removed or become incapable of acting with respect to the
Securities, or if a vacancy shall occur in the office of Trustee with respect to the Securities for
any cause, the Company shall promptly appoint a successor Trustee for the Securities. If, within
one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities 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 with respect to the Securities and supersede the
successor Trustee appointed by the Company with respect to the Securities. If no successor Trustee
with respect to Securities shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner hereinafter provided, any Holder who has been bona fide
Holder of a Security for at least 6 months may, on behalf of himself and all others

35

 

similarly situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to Securities.

     (f) The Company shall give notice of each resignation and each removal of the Trustee with
respect to the Securities and each appointment of a successor Trustee with respect to the
Securities by mailing written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities as their names and addresses appear in the Security Register. Each notice
shall include the name of the successor Trustee and the address of its principal Corporate Trust
Office.

     Section 5.11. Acceptance of Appointment by Successor. Every successor Trustee appointed
hereunder with respect to the Securities shall execute, acknowledge and deliver to the Company and
to the predecessor Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the predecessor Trustee shall become effective, and such successor Trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the predecessor Trustee with respect to the Securities; but, on request of the Company or
the successor Trustee, such predecessor Trustee shall, upon payment of its reasonable charges
(including, but not limited to, attorneys’ fees and expenses), if any, execute and deliver an
instrument, in form and substance reasonably satisfactory to the predecessor Trustee, transferring
to such successor Trustee all the rights, powers and trusts of the predecessor Trustee, and shall
duly assign, transfer and deliver to such successor Trustee all property and money held by such
predecessor 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 rights, powers
and trusts referred to above.

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

     Section 5.12. 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 of the corporate trust business of
the Trustee, shall be the successor of the Trustee hereunder; provided that such corporation shall
be otherwise qualified and eligible under this Article, without the execution or filing of any
paper or any further act on the part of any of the parties hereto. In case any Securities shall
have been authenticated, but not delivered, by the Trustee then in office, any successor Trustee by
merger, conversion or consolidation to such authenticating Trustee may adopt such authentication
and deliver the Securities so authenticated with the same effect as if such successor Trustee had
itself authenticated such Securities.

     Section 5.13. Preferential Collection of Claims Against Company. If and when the Trustee
shall be or shall become a creditor, of the Company (or of any other obligor upon the Securities),
the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection
of claims against the Company (or against any such other obligor, as the case may be).

     Section 5.14. Appointment of Authenticating Agent. At any time when any of the Securities
remain Outstanding, the Trustee, with the approval of the Company, may appoint an

36

 

Authenticating Agent or Agents with respect to the Securities which shall be authorized to act
on behalf of the Trustee to authenticate the Securities upon exchange, registration of transfer or
partial redemption thereof or pursuant to Section 2.09, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws
to act as an Authenticating Agent, having a combined capital and surplus of not less than
U.S.$50,000,000 and, if other than the Company itself, subject to supervision or examination by
federal or state authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such Authenticating Agent
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 an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section,
without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and, if other than the Company, to the Company. The Trustee may at any time terminate the agency
of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and, if
other than the Company, to the Company. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee, with the approval of the Company, may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all Holders of
Securities, as their names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible
under the provisions of this Section.

     The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section.

          If an appointment is made pursuant to this Section, the Securities may have endorsed thereon,
in addition to the Trustee’s certificate of authentication, an alternate certificate of
authentication in the following form:

37

 

          This is one of the Securities referred to in the within-mentioned Indenture.

	 	 	 	 	 
	 	The Bank of New York Mellon, as Trustee

 	 
	 	By:  	 	 
	 	 	As Authenticating Agent 	 
	 	 	 	 
	 	By:  	 	 
	 	 	Authorized Signatory

     Section 6.01. Company May Consolidate, Etc., Only on Certain Terms. The Company shall not
consolidate with or merge into any other Person or convey, transfer, sell or lease its properties
and assets substantially as an entirety to any Person, and the Company shall not permit any Person
to consolidate with or merge into it or convey, transfer, sell or lease such Person’s properties
and assets substantially as an entirety to it, unless:

     (a) the Company is the surviving person or the Person formed by such consolidation or into
which the Company is merged, or the Person to which the Company’s properties and assets are

if any, and interest on all of the Securities, and the performance or observance of every covenant
of this Indenture on the part of the Company to be performed or observed;

     (b) immediately after giving effect to such transaction, no Event of Default, and no event
that, after notice or lapse of time or both, would become an Event of Default, shall have occurred
and be continuing; and

     (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a

shall succeed to, and be substituted for, and may exercise every right and power of, the Company

38

 

relieved of all of its obligations and covenants under this Indenture and the Securities
except with respect to any obligations that arise from, or are related to, such transaction.

ARTICLE 7

Supplemental Indentures

     Section 7.01. Supplemental Indentures Without Consent of Holders. Without the consent of the
Holders of the Outstanding Securities, the Company and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form reasonably satisfactory to

     (h) to comply with the requirements of the Commission in connection with the qualification of
this Indenture under the TIA; or

     (i) to make any change in the Securities that does not adversely affect in any material
respect the interests of the Holders.

     Section 7.02. Supplemental Indentures With Consent of Holders. With the consent of the
Holders of not less than a majority in aggregate principal amount of the Outstanding Securities, by
Act of said Holders delivered to the Company and the Trustee, the Company 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 of any supplemental indenture or of modifying in any manner the

39

 

rights of the Holders of the Securities under this Indenture; provided, however, that no such
supplemental indenture, amendment, modification or supplement shall, without the consent of the
Holder of each Outstanding Security:

interest payable on any Security, or reduce the principal amount thereof, or any amount of interest
or premium payable thereon, or

     (b) change the method of computing the amount of principal of any Security or any interest
payable thereon on any date, or change any Place of Payment where, or the coin or currency in which
any Security or any payment of premium or interest thereon is payable, or

     (c) impair the right to institute suit for the enforcement of any payment described in clauses

hereunder and their consequences, provided for in this Indenture; or

     (e) modify any of the provisions of this Section or Section 4.13, 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 Outstanding Security; provided, however, that this
clause shall not be deemed to require the consent of any Holder with respect to changes in the
references to “the Trustee” and concomitant changes in this Section, or the deletion of this
proviso, in accordance with the requirements of Sections 5.11 and 7.01(g); or

     (f) modify the provisions of this Indenture with respect to the ranking of the Securities in a
manner adverse to the Holders;

     (g) amend or modify the provisions of Article 13 in a manner adverse to the Holders after the
Holders’ right to require the Company to repurchase the Securities upon a Change in Control arises,
except in accordance with the terms of this Indenture; or

     (h) except as permitted by Section 9.11, adversely affect the right to convert any Security as
provided in Article 9.

     It shall not be necessary for any Act of Holders under this Section 7.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such Act
shall approve the substance thereof.

     Section 7.03. Execution of Supplemental Indentures. Upon the written request of the Company
and upon filing with the Trustee of evidence of an Act of Holders as aforementioned, the Trustee
shall join with the Company in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee’s own rights, powers, trusts, 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. In executing, or accepting the additional
trusts created by, any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 5.01) shall be fully protected in relying upon, an Officer’s Certificate
pursuant to

40

 

Section 1.02 hereof and an Opinion of Counsel pursuant to Section 1.02 hereof, each setting
forth the statements required by Section 1.02 and stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture.

     Section 7.04. Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture under this Article, this Indenture shall be and be deemed to be modified and amended in
accordance therewith, and such supplemental indenture shall form a part of this Indenture for all
purposes; and the respective rights, limitation of rights, duties, powers, trusts and immunities
under this Indenture of the Trustee, the Company, and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be determined, exercised and enforced
thereunder to the extent provided therein.

     Section 7.05. Conformity With Trust Indenture Act. Every supplemental indenture executed
pursuant to this Article shall conform to the requirements of the TIA as then in effect.

     Section 7.06. Reference in Securities to Supplemental Indentures. Securities authenticated
and delivered after the execution of any supplemental indenture pursuant to this Article may, and
shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine, new Securities 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 be prepared and executed by the Company
and authenticated and delivered by the Trustee in exchange for Outstanding Securities.

     Section 7.07. Notice of Supplemental Indentures. Promptly after the execution by the Company
and the Trustee of any supplemental indenture pursuant to the provisions of Section 7.02, the
Trustee shall give notice, such notice to be prepared by the Company, to all Holders of Securities
of such fact, setting forth in general terms the substance of such supplemental indenture, in the
manner provided in Section 1.06. Any failure of the Trustee to give such notice, or any defect
therein, shall not in any way impair or affect the validity of any such supplemental indenture.

ARTICLE 8

Covenants

     Section 8.01. Payment of Principal, Premium and Interest. With respect to the Securities, the
Company covenants and agrees that it will duly and punctually pay or cause to be paid the
principal, premium, if any, and interest, in accordance with their terms and this Indenture, and
will duly comply with all the other terms, agreements and conditions contained in the Indenture for
the benefit of the Securities.

     Section 8.02. Maintenance of Office or Agency. With respect to the Securities, so long as any
of the Securities remain outstanding, the Company will maintain an office or agency in each Place
of Payment where Securities may be presented or surrendered for payment, where Securities may be
surrendered for registration of transfer or exchange, where Securities may be surrendered for
conversion, and where notices and demands to or upon the Company in respect of the Securities and
this Indenture may be served. The Company will give prompt written notice to the Trustee of the
location, and of any change in the location, of such office or agency. If at any time the Company
shall fail to maintain such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, conversions, notices and demands may

41

 

be made or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands.

     Section 8.03. Money or Security Payments to Be Held in Trust. If the Company shall at any
time act as its own Paying Agent, it will, on or before each due date of the principal, premium, if
any, or interest, if any, on any of the Securities, segregate and hold in trust for the benefit of
the Holders of the Securities a sum sufficient to pay such principal, premium, or interest so
becoming due until such sums shall be paid to such Holders of such Securities or otherwise disposed
of as herein provided, and will promptly notify the Trustee, in writing, of its action or failure
so to act.

     Whenever the Company shall have one or more Paying Agents for the Securities, it will, on or
prior to each due date of the principal, premium, if any, or interest, if any, deposit with a
Paying Agent a sum sufficient to pay such principal, premium, or interest so becoming due, such sum
to be held in trust for the benefit of the Holders of the Securities entitled to the same and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee, in writing,
of its action or failure so to act.

     The Company will cause each Paying Agent, other than the Trustee, to execute and deliver to
the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will

     (a) hold all sums held by it for the payment of principal, premium, if any, or interest, if
any, on Securities in trust for the benefit of the Holders of the Securities entitled thereto until
such sums shall be paid to such Holders of such Securities or otherwise disposed of as herein
provided;

     (b) give the Trustee written notice of any default by the Company (or any other obligor upon
the Securities) in the making of any such payment of principal, premium, if any, or interest, if
any, on the Securities; and

     (c) at any time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

     The Company may, at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture with respect the Securities or for any other purpose, pay, or by Company Order
direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying
Agent in respect of the Securities as to which it seeks to discharge this Indenture or, if for any
other purpose, all sums so held in trust by the Company in respect of all Securities, such sums to
be held by the Trustee upon the same trusts as those upon which such sums were held by the Company
or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent
shall be released from all further liability with respect to such money.

     Section 8.04. Certificate to Trustee. The Company will deliver to the Trustee, within 120
days after the end of each fiscal year of the Company (beginning in 2010), an Officer’s
Certificate, one of whose signatories shall be the Company’s principal executive, accounting or
financial officer, stating that in the course of the performance by the signer of his or her duties
as officer of the Company they would normally have knowledge of any default by the Company in the
performance of any of its covenants, conditions or agreements contained herein (without

42

 

regard to any period of grace or requirement of notice provided hereunder), stating whether or
not he or she has knowledge of any such default and, if so, specifying each such default of which
the signer has knowledge and the nature thereof.

     Section 8.05. Corporate Existence. Subject to Article 6, 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 8.06. Covenant as to Common Stock. The Company agrees that all shares of Common Stock
that may be delivered upon conversion of any Securities to which Article 9 applies, upon such
delivery, will be newly issued shares and will have been duly authorized and validly issued and
will be fully paid and nonassessable and, except as provided in Section 9.08, the Company will pay
all taxes, liens and charges with respect to the issue thereof.

     Section 8.07. Limitation on Incurrence of Senior Debt. The Company may not create, issue,
incur (by conversion, exchange or otherwise), assume, guarantee or otherwise become liable in
respect of any obligation evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property, assets or
businesses, but excluding any trade payments and other accrued current liabilities arising in the
ordinary course of business, unless such liability is, by its terms, subordinate in right of
payment to the Securities. Notwithstanding the foregoing, the Company may incur such liability in
the event the aggregate principal amount of Outstanding Securities is equal to or less than
$5,000,000.

ARTICLE 9

Conversion of Securities

     Section 9.01. Conversion Privilege and Conversion Rate. Subject to and upon compliance with
the provisions of this Article 9, at the option of the Holder thereof, any Security or any portion
of the principal amount thereof that is U.S.$2,000 or an integral multiple of U.S.$1,000 may be
converted into fully paid and nonassessable shares (calculated as to each conversion to the nearest
1/100th of a share) of Common Stock at the Conversion Rate, determined as hereinafter provided, in
effect at the time of conversion. Such conversion right shall commence upon the original issuance
of the Securities and expire at the close of business two (2) New York Business Days prior to the
Maturity, unless such Security has been previously repurchased, redeemed or converted. The rate at
which shares of Common Stock shall be delivered upon conversion (herein called the “Conversion
Rate”) shall be initially 1098 shares of Common Stock for each U.S.$1,000 principal amount of
Securities. The Conversion Rate shall be adjusted in certain instances as provided in this Article
9.

     Section 9.02. Exercise of Conversion Privilege. In order to exercise the conversion
privilege, the Holder of any Security to be converted shall surrender such Security, duly endorsed
or assigned to the Company or in blank, at any office or agency of the Company maintained for that
purpose pursuant to Section 8.02, accompanied by a duly signed and completed notice of conversion
(substantially in the form attached hereto as Exhibit A) stating that the Holder elects to
convert such Security or, if less than the entire principal amount thereof is to be converted, the
portion thereof to be converted. The interest so payable on such Interest Payment Date, with
respect to any Security (or portion thereof, if applicable) that is surrendered for conversion
during the period from the close of business on any Record Date next preceding any Interest Payment

43

 

Date to the opening of business on such Interest Payment Date, shall be paid to the Holder of
such Security as of such Record Date. Interest payable in respect of any Security surrendered for
conversion on or after an Interest Payment Date shall be paid to the Holder of such Security as of
the next preceding Record Date, notwithstanding the exercise of the right of conversion. Except as
provided in this paragraph, no cash payment or adjustment shall be made upon any conversion on
account of any interest accrued from the Interest Payment Date next preceding the Conversion Date,
in respect of any Security (or part thereof, as the case may be) surrendered for conversion, or on
account of any dividends on the Common Stock issued upon conversion. The Company’s delivery to the
Holder of the number of shares of Common Stock (and cash in lieu of fractions thereof as provided
in Section 9.03) into which a Security is convertible and any rights pursuant to Section 9.04(m)
will be deemed to satisfy the Company’s obligation to pay the principal amount of the Security.

     Securities shall be deemed to have been converted on the day of surrender of such Securities
for conversion in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive
the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or
holders of such Common Stock at such time. As promptly as practicable on or after the Conversion
Date, the Company shall issue and deliver to the Conversion Agent, for delivery to the Holder, a
certificate or certificates for the number of full shares of Common Stock issuable upon conversion,
together with payment in lieu of any fraction of a share, as provided in Section 9.03.

     Neither the Trustee nor the Conversion Agent shall have any responsibility for the inclusion
or content of any restrictive legends on such Common Stock; provided, however, that the Trustee or
the Conversion Agent shall have provided to the Company or to the Company’s transfer agent for such
Common Stock, prior to or concurrently with a request to the Company to deliver such Common Stock,
written notice that the securities delivered for conversion are Securities.

     In the case of any Security that is converted in part only, upon such conversion 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 Security or Securities of authorized denominations in
an aggregate principal amount equal to the unconverted portion of the principal amount of such
Security. A Security may be converted in part, but only if the principal amount of such Security
to be converted is equal to U.S.$2,000 or any integral multiple of U.S.$1,000 in excess thereof and
the principal amount of such security to remain Outstanding after such conversion is equal to
U.S.$2,000 or any integral multiple of U.S.$1,000 in excess thereof. Notwithstanding anything to
the contrary contained herein, the number of Conversion Shares that may be acquired by the Holder
upon any conversion of the Securities (or otherwise in respect hereof) shall be limited to the
extent necessary to insure that, following such conversion (or other issuance), the total number of
shares of Common Stock then beneficially owned by such Holder and its affiliates (as defined under
Rule 144 promulgated under the Securities Act, “Affiliates”) and any other persons whose beneficial
ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of
the Exchange Act, does not exceed 4.999% of the total number of issued and outstanding shares of
Common Stock (including for such purpose the shares of Common Stock issuable upon such
conversion).  For such purposes, beneficial ownership shall be determined in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.  The Holder
may waive the provisions of this

44

 

Section 9.02 by written notice to the Company to change the beneficial ownership limitation to
9.999%, but any such waiver will not be effective until the 61st day after delivery of such notice,
nor will any such waiver effect any other Holder. Upon such a change by such Holder of the
beneficial ownership limitation from such 4.99% limitation to such 9.99% limitation, the beneficial
ownership limitation may not be further waived by such Holder except in the event of a Change in
Control. The provisions of this paragraph shall be construed and implemented in a manner otherwise
than in strict conformity with the terms of this Section to correct this paragraph (or any portion
hereof) which may be defective or inconsistent with the intended beneficial ownership limitation of
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder herein or to
make changes or supplements necessary or desirable to properly give effect to such limitation. The
limitations contained in this paragraph shall apply to a successor Holder.

     Unless and until the Conversion Agent receives an Officer’s Certificate from the Company
notifying the Trustee that, upon a conversion of Securities, a Holder would own in excess of 4.99%
of the total number of issued and outstanding shares of Common Stock (including for such purpose
the shares of Common Stock issuable upon such conversion), the Conversion Agent may assume without
inquiry (i) that no Holder owns or upon a conversion of Securities would own in excess of that
number and (ii) that each Holder is in compliance with the requirements of this Section 9.02.

     Section 9.03. Fractions of Shares. No fractional shares of Common Stock shall be issued upon
conversion of any Security or Securities. If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares that shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal amount of the
Securities (or specified portions thereof) so surrendered. Instead of any fractional share of
Common Stock that would otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall calculate and pay a cash adjustment in respect of
such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same
fraction of the Closing Price at the close of business on the day of conversion.

     Section 9.04. Adjustment of Conversion Rate. The Conversion Rate shall be subject to
adjustments from time to time as follows:

     (a) In case the Company shall pay or make a dividend or other distribution on any class of
Capital Stock of the Company payable 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 (subject to paragraph (l) of this Section
9.04) immediately after the opening of business on the day following the date fixed for such
determination. For the purposes of this paragraph (a), 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. In no event shall this paragraph (a) apply in the case of an
ordinary dividend.

45

 

     (b) In case the Company shall issue rights, options or warrants to all holders of its Common
Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less
than the current market price per share (determined as provided in paragraph (h) of this Section
9.04) of the Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than any rights, options or warrants (1) that by
their terms will also be issued to any Holder upon conversion of a Security into shares of Common
Stock without any action required by the Company or any other Person or (2) that are only
exercisable upon the occurrence of a specified triggering event and such triggering event has not
occurred), 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 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 plus the number of shares of Common Stock which
the aggregate of the offering price of the total number of shares of Common Stock so offered for
subscription or purchase would purchase at such current market price and the denominator 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 (subject to paragraph (l) of this 9.04) immediately
after the opening of business on the day following the date fixed for such determination. For the
purposes of this paragraph (b), 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.

     (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock, the Conversion Rate in effect at the opening of business on the day
following the day upon which such subdivision becomes effective shall be proportionately increased,
and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller
number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the
day following the day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective immediately after the
opening of business on the day following the day upon which such subdivision or combination becomes
effective.

     (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its
Common Stock evidences of its Indebtedness, shares of any class of Capital Stock, or other property
(including cash or assets or securities, but excluding (1) any rights, options or warrants referred
to in paragraph (b) of this Section 9.04 and the distribution of rights to all holders of Common
Stock pursuant to the adoption of a stockholders’ rights plan or the detachment of such rights
under the terms of such stockholders’ rights plan, (2) any dividend or distribution paid in cash,
except as set forth in paragraphs (e) and (f) of this Section 9.04 and (3) any dividend or
distribution referred to in paragraph (a) of this Section 9.04, the Conversion Rate shall be
adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect
immediately prior to the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator shall be the current
market price per share (determined as provided in paragraph (h) of this Section 9.04) of the Common
Stock on the date fixed for such determination less the then fair market value (as determined by
the Board of Directors, whose determination shall be conclusive and described in a Board
Resolution) of the portion of the assets, shares or evidences of Indebtedness so distributed

46

 

applicable to one share of Common Stock and the denominator shall be such current market price
per share (determined as provided in paragraph (h) of this Section 9.04) of the Common Stock, such
adjustment to become effective (subject to paragraph (l) of this Section 9.04) immediately prior to
the opening of business on the day following the date fixed for the determination of stockholders
entitled to receive such distribution.

     (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its
Common Stock cash (excluding cash portions of distribution referred to in Section 9.04(d) and any
cash that is distributed upon a merger or consolidation to which Section 9.11 applies) in an
aggregate amount that, combined together with (1) the aggregate amount of any other cash
distributions to all holders of its Common Stock made exclusively in cash within the 365-day period
preceding the date of payment of such distribution and in respect of which no adjustment pursuant
to this paragraph (e) has been made and (2) the aggregate of any cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be conclusive and described in
a Board Resolution) of other consideration payable in respect of any tender offer by the Company or
any Subsidiary for all or any portion of the Common Stock concluded within the 365-day period
preceding the date of payment of such distribution and in respect of which no adjustment pursuant
to paragraph (f) of this Section 9.04 has been made (the “Combined Cash and Tender Amount”) exceeds
ten percent (10%) of the product of the current market price per share (determined as provided in
paragraph (h) of this Section 9.04) of the Common Stock on the date for the determination of
holders of shares of Common Stock entitled to receive such distribution times the number of shares
of Common Stock outstanding on such date (the “Aggregate Current Market Price”), then, and in each
such case, immediately after the close of business on such date for determination, subject to
paragraph (l) of Section 9.04, the Conversion Rate shall be adjusted so that the same shall equal
the rate determined by dividing 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 (determined as provided in paragraph (h) of this Section 9.04) of the Common Stock on the
date fixed for such determination less an amount equal to the quotient of (i) the excess of such
Combined Cash and Tender Amount over ten percent (10%) of such Aggregate Current Market Price
divided by (ii) the number of shares of Common Stock outstanding on such date fixed for
determination and (B) the denominator of which shall be equal to the current market price per share
(determined as provided in paragraph (h) of this Section 9.04) of the Common Stock on such date
fixed for determination.

     (f) In case a tender offer made by the Company or any Subsidiary for all or any portion of the
Common Stock shall be completed for an aggregate consideration consisting of cash and/or property
having a fair market value (as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) that combined together with (1) the aggregate of
the cash plus the fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a Board Resolution), of other consideration payable in respect
of any other tender offer by the Company or any Subsidiary for all or any portion of the Common
Stock concluded within the 365-day period preceding the completion of such tender offer and in
respect of which no adjustment pursuant to this paragraph (f) has been made and (2) the aggregate
amount of any distributions to all holders of the Company’s Common Stock made exclusively in cash
within the 365-day period preceding the completion of such tender offer and in respect of which no
adjustment pursuant to paragraph (e) of this Section 9.04 has been made (the “Combined Tender and
Cash Amount”) exceeds ten percent (10%) of the product of the current market price per share of the
Common Stock

47

 

(determined as provided in paragraph (h) of this Section 9.04) as of the completion of such
tender offer (the “Completion Date”) times the number of shares of Common Stock outstanding
(including any tendered shares) as of the Completion Date, then, and in each such case, immediately
prior to the opening of business on the day after the date of the Completion Date, the Conversion
Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion
Rate immediately prior to close of business on the Completion Date by a fraction (A) the numerator
of which shall be equal to (i) the product of (x) the current market price per share of the Common
Stock (determined as provided in paragraph (h) of this Section 9.04) on the Completion Date
multiplied by (y) the number of shares of Common Stock outstanding (including any tendered shares)
on the Completion Date less (ii) the Combined Tender and Cash Amount, and (B) the denominator of
which shall be equal to the product of (x) the current market price per share of the Common Stock
(determined as provided in paragraph (h) of this Section 9.04) as of the Completion Date multiplied
by (y) the number of shares of Common Stock outstanding (including any tendered shares) as of the
Completion Date less the number of all shares validly tendered and not withdrawn as of the
Completion Date.

     (g) The reclassification of Common Stock into securities including other than Common Stock
(other than any reclassification upon a consolidation or merger to which Section 9.11 applies)
shall be deemed to involve (1) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall be deemed to be “the
date fixed for the determination of stockholders entitled to receive such distribution” and “the
date fixed for such determination” within the meaning of paragraph (d) of this Section 9.04), and
(2) a subdivision or combination, as the case may be, of the number of shares of Common Stock
outstanding immediately prior to such reclassification into the number of shares of Common Stock
outstanding immediately thereafter (and the effective date of such reclassification shall be deemed
to be “the day upon which such subdivision becomes effective” or “the day upon which such
combination becomes effective”, as the case may be, and “the day upon which such subdivision or
combination becomes effective” within the meaning of paragraph (c) of this Section 9.04).

     (h) For the purpose of any computation under paragraphs (b), (d), (e) or (f) of this Section
9.04, the current market price per share of Common Stock on any date shall be calculated by the
Company and be deemed to be the Volume Weighted Average Price for the Trading Day before the “ex
date” with respect to the issuance or distribution requiring such computation. For purposes of
this paragraph, the term “ex date,” when used with respect to any issuance or distribution, means
the first date on which the Common Stock trades regular way in the applicable securities market or
on the applicable securities exchange without the right to receive such issuance or distribution.

     (i) No adjustment in the Conversion Rate shall be required unless such adjustment (plus any
adjustments not previously made by reason of this paragraph (i)) would require an increase or
decrease of at least one percent in such rate; provided, however, that any adjustments which by
reason of this paragraph (i) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Article 9 shall be made to the
nearest cent or to the nearest one-hundredth of a share, as the case may be.

     (j) The Company may make such increases in the Conversion Rate, for the remaining term of the
Securities or any shorter term, in addition to those required by paragraphs (a), (b), (c), (d), (e)
and (f) of this Section 9.04, as it considers to be advisable in order to avoid or diminish any
income tax liability to any holders of shares of Common Stock resulting from any

48

 

dividend or distribution of Common Stock or issuance of rights or warrants to purchase or
subscribe for Common Stock or from any event treated as such for income tax purposes.

     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 and
the Board of Directors shall have made a determination that such increase would be in the best
interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is
increased pursuant to the preceding sentence, the Company shall give notice of the increase to the
Holders of Securities in the manner provided in Section 1.06 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.

     (k) Notwithstanding the foregoing provisions of this Section 9.04, no adjustment of the
Conversion Rate shall be required to be made (1) upon the issuance of shares of Common Stock
pursuant to any present or future plan for the reinvestment of dividends, (2) because of a tender
or exchange offer of the character described in Rule 13e-4(h)(5) under the Exchange Act or any
successor rule thereto or (3) as a result of a rights plan or poison pill implemented by the
Company.

     (l) In any case in which this Section 9.04 shall require that an adjustment be made
immediately following a Record Date, the Company may elect to defer the effectiveness of such
adjustment (but in no event until a date later than the effective time of the event giving rise to
such adjustment), in which case the Company shall, with respect to any Security to which this
Article 9 applies, converted after such Record Date and on and before such adjustment shall have
become effective (1) defer paying any cash payment pursuant to Section 9.03 hereof or issuing to
the Holder of such Security the number of shares of Common Stock issuable upon such conversion in
excess of the number of shares of Common Stock issuable thereupon only on the basis of the
Conversion Rate prior to adjustment, and (2) not later than five (5) New York Business Days after
such adjustment shall have become effective, pay to such Holder the appropriate cash payment
pursuant to Section 9.03 hereof and issue to such Holder the additional shares of Common Stock
issuable on such conversion. Notwithstanding the foregoing, no adjustment of the Conversion Rate
shall be made if the event giving rise to such adjustment does not occur.

     (m) In the event that the Company distributes rights or warrants (other than those referred to
in paragraph (b) above) pro rata to holders of Common Stock, so long as any such rights or warrants
have not expired, the Company shall make proper provision so that the Holder of any Security to
which this Article 9 applies, surrendered for conversion will be entitled to receive upon such
conversion, in addition to the Common Stock issuable upon conversion of the Securities (the
“Conversion Shares”), a number of rights and warrants to be determined as follows: (i) if such
conversion occurs on or prior to the date for the distribution to the holders of rights or warrants
of separate certificates evidencing such rights or warrants (the “Distribution Date”), the same
number of rights or warrants to which a holder of a number of shares of Common Stock equal to the
number of Conversion Shares is entitled at the time of such conversion in accordance with the terms
and provisions of and applicable to the rights or warrants, and (ii) if such conversion occurs
after such Distribution Date, the same number of rights or warrants to which a holder of the number
of shares of Common Stock into which the principal amount of such Security so converted was
convertible immediately prior to such Distribution Date would have been entitled on such
Distribution Date in accordance with the terms and provisions of and applicable to the rights or
warrants.

49

 

     (n) Notwithstanding anything to the contrary, in the event that the Company shall effect any
increase in the Conversion Rate pursuant to this Section 9.04, the Company shall procure any
required shareholder approvals.

     Section 9.05. Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate is
adjusted as herein provided:

     (a) the Company shall compute the adjusted Conversion Rate in accordance with Section 9.04 and
shall prepare a certificate signed by the President and Chief Executive Officer or the Senior Vice
President and Chief Financial Officer of the Company setting forth the adjusted Conversion Rate and
showing in reasonable detail the facts upon which such adjustment is based, and such certificate
shall promptly be delivered to the Trustee and the Conversion Agent; and

     (b) 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
1.06.

     Neither the Trustee nor the 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 any Securities to which this Article 9 applies, desiring
inspection thereof at its office during normal business hours. Unless and until a Responsible
Officer of the Trustee and Conversion Agent receive notice of an adjusted Conversion Rate, the
Trustee and the Conversion Agent may rely without inquiry on the Conversion Rate most recently in
effect.

     Section 9.06. Notice of Certain Corporate Action. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock
payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would
require any adjustment pursuant to Section 9.04; or

     (b) the Company shall authorize the granting to the holders of its Common Stock of rights,
options or warrants to subscribe for or purchase any shares of Capital Stock of any class or of any
other rights; or

     (c) of any reclassification of the Common Stock of the Company, or of any consolidation,
merger or share exchange to which the Company is a party and for which approval of any stockholders
of the Company is required, or of the conveyance, sale, transfer or lease 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;

then the Company shall cause to be delivered to the Trustee and Conversion Agent at each office or
agency maintained for the purpose of conversion of any Securities to which this Article 9 applies
pursuant to Section 9.02, and shall cause to be provided to all Holders in accordance with Section
1.06, at least twenty (20) days prior to the applicable record or effective date hereinafter
specified, a notice stating (1) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date
as of

50

 

which the holders of Common Stock of record to be entitled to such dividend, distribution, rights,
options or warrants are to be determined or (2) the date on which such reclassification,
consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up is
expected to become effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, conveyance, transfer, sale,
lease, dissolution, liquidation or winding up. Neither the failure to give such notice or the
notice referred to in the following paragraph nor any defect therein shall affect the legality or
validity of the proceedings described in clauses (a) through (d) of this Section 9.06. If at the
time the Trustee shall not be the Conversion Agent, a copy of such notice shall also forthwith be
delivered by the Company to the Trustee.

     The Company shall cause to be delivered to the Trustee and Conversion Agent at each office or
agency maintained for the purpose of conversion of any Securities to which this Article 9 applies
pursuant to Section 8.02, and shall cause to be provided to all Holders in accordance with Section
1.06, notice of any tender offer by the Company or any Subsidiary for all or any portion of the
Common Stock at or about the time that such notice of tender offer is provided to the public
generally.

     Section 9.07. Company to Reserve Common Stock. The Company shall at all times reserve and
keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for
the purpose of effecting the conversion of any Securities to which this Article 9 applies, the full
number of shares of Common Stock then issuable upon the conversion of all Outstanding Securities.

     Section 9.08. Taxes on Conversions. Except as provided in the next sentence, the Company will
pay any and all taxes and duties that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of any Securities to which this Article 9 applies pursuant hereto.
The Company shall not, however, be required to pay any tax or duty which may be payable in respect
of any transfer involved in the issue and delivery of shares of Common Stock in a name other than
that of the Holder of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the Company the amount
of any such tax or duty or has established to the satisfaction of the Company that such tax or duty
has been paid.

     Section 9.09. Reserved.

     Section 9.10. Cancellation of Converted Securities. All Securities to which this Article 9
applies delivered for conversion shall be delivered to the Trustee or the Conversion Agent to be
cancelled by or at the direction of the Trustee, which shall dispose of the same in accordance with
Section 2.13 hereof.

     Section 9.11. Provision in Case of Consolidation, Merger or Sale of Assets. In case of any
consolidation or merger of the Company with or into any other Person, any merger of another Person
with or into the Company (other than a merger that does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets of the Company, the
Person formed by such consolidation or resulting from such merger or that acquires such assets, as
the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security to which this Article 9 applies then Outstanding shall have the

51

 

right thereafter, during the period such Security shall be convertible as specified in Section
9.01, to convert such Security only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer or lease by a holder of the
number of shares of Common Stock of the Company into which such Security might have been converted
immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such
holder of Common Stock of the Company (a) is not a Person with which the Company consolidated or
merged with or into or that merged into or with the Company or to which such conveyance, sale,
transfer or lease was made, as the case may be (a “Constituent Person”), or an Affiliate of a
Constituent Person and (b) failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is
not the same for each share of Common Stock of the Company held immediately prior to such
consolidation, merger, conveyance, sale, transfer or lease by other than a Constituent Person or an
Affiliate thereof and in respect of which such rights of election shall not have been exercised
(the “Non-electing Share”), then for the purpose of this Section 9.11 the kind and amount of
securities, cash and other property receivable upon such consolidation, merger, conveyance, sale,
transfer or lease by the holders of each Non-electing Share shall be deemed to be the kind and
amount so receivable per share by a plurality of the Non-electing Shares). Such supplemental
indenture shall provide for adjustments that, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 9. The above provisions of this Section 9.11 shall similarly apply to
successive consolidations, mergers, conveyances, sales, transfers or leases. Notice of the
execution of such a supplemental indenture shall be given by the Company to the Holder of each
Security to which this Article 9 applies as provided in Section 1.06 promptly upon such execution.

     Neither the Trustee nor the Conversion Agent shall be under any responsibility to determine
the correctness of any provisions contained in any such supplemental indenture relating either to
the kind or amount of shares of stock or other securities or property or cash receivable by Holders
of any Securities to which this Article 9 applies upon the conversion of their Securities after any
such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment but may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, an Officers Certificate or an Opinion of Counsel with respect thereto, which the
Company shall cause to be furnished to the Trustee in accordance with Section 1.02.

     Section 9.12. Responsibility of Trustee for Conversion Provisions. The Trustee and any
Conversion Agent shall not at any time be under any duty or responsibility to any Holder of
Securities to which this Article 9 applies to determine whether any facts exist that may require
any adjustment of the Conversion Rate, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed herein or in any supplemental
indenture in making the same, or to monitor beneficial ownership limitations of common stock set
forth in Sections 9.02 or 9.13 hereof, or whether a supplemental indenture need be entered into.
Neither the Trustee nor any Conversion Agent shall be accountable with respect to the validity or
value (or the kind or amount) of any Common Stock, or of any other securities or property or cash,
that may at any time be issued or delivered upon the conversion of any Security; and it or they do
not make any representation with respect thereto. Neither the Trustee, subject to the provisions
of Section 5.01, nor any Conversion Agent shall be responsible for any failure of the Company to
make or calculate any cash payment or to issue, transfer or deliver any shares of

52

 

Common Stock or share certificates or other securities or property or cash upon the surrender
of any Security for the purpose of conversion; and the Trustee and any Conversion Agent shall not
be responsible for any failure of the Company to comply with any of the covenants of the Company
contained in this Article 9.

     Section 9.13. Automatic Conversion.

     (a) If at any time after February [ ], 2010 and on or prior to Maturity, the Closing Price
of the Common Stock is equal to or greater than U.S.$1.72 per share for at least twenty (20)
Trading Days in any thirty (30) consecutive Trading Day period, ending within five (5) Trading Days
prior to the date of the Automatic Conversion Notice (as defined below) the Securities shall
automatically convert as provided herein (an “Automatic Conversion”); provided, however, that such
Automatic Conversion shall be subject to Section 9.02 hereof. In the event less than all of the
Outstanding Securities can be automatically converted due to the beneficial ownership limitations
of a Holder under Section 9.02, the maximum amount of Outstanding Securities as to such Holder
shall be so converted pursuant to the Automatic Conversion.

     (b) At the request and expense of the Company, the Trustee shall mail or cause to be mailed to
each Holder of Outstanding Securities a notice (the “Automatic Conversion Notice”), such notice to
be prepared by the Company, of an Automatic Conversion not more than thirty (30) days but not less
than twenty (20) days prior to the date on which the Securities will be Automatically Converted
(the “Automatic Conversion Date”). If the Company gives such notice, it shall also deliver a copy
of such Automatic Conversion Notice to the Trustee. Such mailing shall be by first class mail.
Such 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 Security shall not affect the
validity of the proceedings for the Automatic Conversion of any other Security.

     (c) Each Automatic Conversion Notice shall state:

     (1) the aggregate principal amount of Securities to be automatically converted,

     (2) the CUSIP, ISIN or similar number or numbers of the Securities being automatically
converted, if applicable,

     (3) the Automatic Conversion Date,

     (4) the Make-Whole Payment,

     (5) the place or places where the Securities are to be surrendered for conversion, and

     (6) the Conversion Rate then in effect.

     (d) Prior to or contemporaneous with the mailing of an Automatic Conversion Notice to the
Holders, the Company shall issue a press release containing the information contained in the
Automatic Conversion Notice.

53

 

     (e) In the event of an Automatic Conversion, the Company shall issue and deliver a certificate
or certificates for the number of Conversion Shares as promptly after the Automatic Conversion
Date, as practicable in accordance with the provisions of this Article 9, but in no event later
than the close of business on the fifth next succeeding Business Day following such Automatic
Conversion Date.

     (f) All Securities subject to an Automatic Conversion shall be delivered to the Trustee or the
Conversion Agent to be cancelled by or at the direction of the Trustee, which shall dispose of the
same in accordance with Section 2.13.

     (g) If less than all the Securities are to be Automatically Converted, the particular
Securities to be converted shall be selected by the Trustee at least five (5) New York Business
Days prior to the date that the Automatic Conversion Notice is given from the Outstanding
Securities by lot or such method as the Trustee may deem fair and appropriate.

     (h) Upon Automatic Conversion, interest on the Securities shall cease to accrue and, except as
provided in Section 5.06, to be entitled to any benefit or security under this Indenture, and the
Holders thereof shall have no right in respect of such Securities except the right to receive the
Common Stock and cash, if any, to which they are entitled pursuant to this Section 9.13.

     (i) If any of the provisions of this Section 9.13 are inconsistent with applicable law at the
time of such Automatic Conversion, such law shall govern.

     (j) Notwithstanding anything to the contrary, in the event that the Company shall effect
Automatic Conversion pursuant to this Section 9.13, the Company shall procure any required
stockholder approvals.

ARTICLE 10

Make-Whole Payment

     Section 10.01. Make-Whole Provision. Upon the conversion or repurchase of any Security prior
to its Maturity, the Company will pay to the Holders of the Securities so converted or repurchased
cash with respect to the Security so converted or repurchased, in an amount equal to U.S.$379.121
per U.S.$1,000 principal amount of the Securities, less the amount of any interest paid on the
Securities from the date of issuance until the relevant Conversion Date or Repurchase Date (the
“Make-Whole Payment”). The Company shall pay the Make-Whole Payment within five (5) business days
of the applicable Conversion Date or Repurchase Date is completed, in all cases pursuant to the
terms of this Indenture.

ARTICLE 11

Holders Lists And Reports By Trustee And Company; Non-Recourse

     Section 11.01. Company to Furnish Trustee Names and Addresses of Holders. The Company will
furnish or cause to be furnished to the Trustee:

     (a) semi-annually, not more than fifteen (15) days after the Record Date, a list, in such form
as the Trustee may reasonably require, of the names and addresses of the Holders of Outstanding
Securities as of such Record Date, and

54

 

     (b) at such other times as the Trustee may reasonably request in writing, within thirty (30)
days after the receipt by the Company of any such request, a list of similar form and content as of
a date not more than fifteen (15) days prior to the time such list is furnished;

provided, however, that no such list need be furnished so long as the Trustee is acting as Security
Registrar.

     Section 11.02. Preservation of Information.

     (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names
and addresses of Holders contained in the most recent list furnished to the Trustee as provided in
Section 11.01 and the names and addresses of Holders received by the Trustee in its capacity as
Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 11.01
upon receipt of a new list so furnished.

     (b) After this Indenture has been qualified under the Trust Indenture Act, the rights of
Holders to communicate with other Holders with respect to their rights under this Indenture or
under the Securities, and the corresponding rights and duties of the Trustee, shall be as provided
by the Trust Indenture Act.

     (c) Every Holder of Securities, 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 made
pursuant to the Trust Indenture Act.

     Section 11.03. No Recourse Against Others. An incorporator or any past, present or future
director, officer, employee or stockholder, as such, of the Company or any successor entity shall
not have any liability for any obligations of the Company under the Securities or this Indenture or
for any claim based on, in respect of or by reason of such obligations or their creation. By
accepting a Security, each Holder shall waive and release all such liability. Such waiver and
release shall be part of the consideration for the issue of the Securities.

     Section 11.04. Reports by Trustee.

     (a) After this Indenture has been qualified under the Trust Indenture Act, the Trustee shall
transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may
be required pursuant to the Trust Indenture Act at the times and in the manner provided therein.
If required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within sixty (60) days
after each May 15 following the date of this Indenture, deliver to Holders a brief report, dated as
of such May 15, that complies with the provisions of such Section 313(a).

     (b) After this Indenture has been qualified under the Trust Indenture Act, a copy of each such
report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock
exchange upon which the Securities are listed, with the Commission and with the Company. The
Company will promptly notify the Trustee when the Securities are listed on any stock exchange other
than The Nasdaq Capital Market.

     Section 11.05. Section 13 or 15(d) Reports by Company. After this Indenture has been
qualified under the Trust Indenture Act, the Company shall file with the Trustee and the
Commission, and transmit to Holders, such information, documents and other reports, and such

55

 

summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in
the manner provided therein; provided, however, that any such information, documents or reports
required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall
be filed with the Trustee within fifteen (15) days after the same has been filed with the
Commission. Documents filed by the Company with the Commission via the EDGAR system shall be
deemed to be filed with the Trustee as of the time such documents are filed via EDGAR.

     Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt thereof 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 Officer’s Certificates).

ARTICLE 12

Subordination

     Section 12.01. Agreement to Subordinate.

     The Company agrees, and each Holder by accepting a Security agrees, that the payment of
principal of, premium, if any, and interest on, and all other amounts payable in respect of, the
Securities is subordinated in right of payment, to the extent and in the manner provided in this
Article 12 and subject to the provisions of Article 3 hereof, to the payment when due in cash of
all Senior Debt of the Company and that the subordination is for the benefit of and enforceable by
the holders of such Senior Debt. All provisions of this Article 12 shall be subject to Article 3.

     Section 12.02. Liquidation, Dissolution, Bankruptcy.

     (a) Upon any payment or distribution of the assets of the Company to creditors upon a
liquidation, dissolution or winding up of the Company or in a bankruptcy, reorganization,
receivership or similar proceeding relating to the Company or its property or upon an assignment
for the benefit of the Company’s creditors or the marshaling of its assets and liabilities, the
holders of Senior Debt will be entitled to receive payment in full in cash before the Holders of
the Securities are entitled to receive any payment of principal of, premium, if any, or interest,
on, the Securities, except that Holders of Securities may receive and retain such payments made in
Permitted Junior Securities and payments from the trust described in Article 3 hereof.

     (b) Until the Senior Debt is paid in full in cash, any distribution to which Holders of the
Securities would be entitled but for this Article 12 will be made to holders of the Senior Debt as
their interests may appear (except that Holders of Securities may receive and retain payments made
in Permitted Junior Securities and payments and other distributions made from the trust described
in Article 3 hereof; provided that (i) no Holder of the Securities shall have the right to receive
and retain any such Permitted Junior Securities if the existence of such right would have the
effect of causing the Securities to be treated in the same class of claims as the Senior Debt of
the Company or any class of claims which is pari passu with such Senior Debt and (ii) holders of
Senior Debt shall be entitled to receive any cash payments made to any Holder of Securities on the
account of Permitted Junior Securities until all Obligations in respect of Senior Debt have been
paid in full in cash).

56

 

     Section 12.03. Default on Senior Debt.

     The Company may not pay (except in Permitted Junior Securities or from the trust described in
Article 3 hereof) principal of, or premium, if any, or interest on, the Securities, or make any
deposit in respect of the Securities pursuant to Section 4.06, and may not repurchase, redeem or
otherwise retire any Securities (collectively, “pay the Securities”) if (a) any principal, premium,
interest or any other amount payable in respect of any Senior Debt is not paid within any
applicable grace period (including at maturity) or (b) any other default on Senior Debt occurs and
the maturity of such Senior Debt is accelerated in accordance with its terms unless, in either
case, (1) the default has been cured or waived and any such acceleration has been rescinded or (2)
such Senior Debt has been paid in full in cash; provided, however, that the Company may pay the
Securities without regard to the foregoing if the Company and the Trustee receive written notice
approving such payment from the representative of the holders of such Senior Debt or, if there is
no representative, from the holders of such Senior Debt.

     Section 12.04. Acceleration of Payment of Securities.

     If payment of the Securities is accelerated when Senior Debt is outstanding, the Company may
not pay the Securities until three New York Business Days after the representative of the holders
of such Senior Debt or, if there is no Representative, the holders of such Senior Debt receive
notice of such acceleration and, thereafter, may pay the Securities only if this Indenture
otherwise permits payment at that time.

     Section 12.05. When Distribution Must Be Paid Over.

     If a payment or distribution is made to Holders that because of this Article 12 should not
have been made to them, the Trustee or the Holders who receive the distribution shall hold it in
trust for holders of Senior Debt and pay it over to them or their representative as their interests
may appear.

     Section 12.06. Subrogation.

     After all Senior Debt is paid in full and until the Securities are paid in full, Holders shall
be subrogated (equally and ratably with all other Indebtedness that is pari passu with the
Securities) to the rights of holders of Senior Debt to receive distributions applicable to Senior
Debt to the extent that distributions otherwise payable to the Holders have been applied to the
payment of Senior Debt. A distribution made under this Article 12 to holders of Senior Debt that
otherwise would have been made to Holders is not, as between the Company and Holders, a payment by
the Company on such Senior Debt.

     Section 12.07. Relative Rights.

     This Article 12 defines the relative rights of Holders and holders of Senior Debt. Nothing in
this Indenture shall:

     (a) impair, as between the Company and Holders, the obligation of the Company, which is
absolute and unconditional, to pay principal of, premium, if any, and interest on, the Securities
in accordance with their terms;

57

 

     (b) affect the relative rights of Holders and creditors of the Company other then their rights
in relation to holders of Senior Debt; or

     (c) prevent the Trustee or any Holder from exercising its available remedies upon a default or
an Event of Default, subject to the rights of holders of Senior Debt to receive distributions
otherwise payable to Holders.

     Section 12.08. Subordination May Not Be Impaired by Company.

     No right of any holder of Senior Debt to enforce the subordination of the Securities shall be
impaired by any act or failure to act by the Company or by its failure to comply with this
Indenture.

     Section 12.09. Rights of Trustee and Paying Agent.

     The Company shall give prompt written notice to the Trustee of any fact known to the Company
which would prohibit the making of any payment to or by the Trustee in respect of the Securities.
Failure to give such notice shall not affect the subordination of the Securities to Senior Debt.
Notwithstanding the provisions of this or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee in respect of the Securities, unless and until the Trustee shall have
received written notice thereof at the address specified in Section 1.05 from the Company or a
holder of Senior Debt or from any trustee or agent therefor; and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of Section 5.01, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if a
Responsible Officer of the Trustee shall not have received, at least three New York Business Days
prior to the date upon which by the terms hereof any such money may become payable for any purpose
(including, without limitation, the payment of the principal amount, Conversion Price, or interest,
if any, as the case may be, in respect of any Security), the notice with respect to such money
provided for in this Section 12.09, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be affected by any notice
to the contrary which may be received by it within three New York Business Days prior to such date.

     Subject to the provisions of Section 5.01, the Trustee shall be entitled to conclusively rely
on the delivery to it of a written notice by a person representing himself to be a holder of Senior
Debt (or a trustee or agent on behalf of such holder) to establish that such notice has been given
by a holder of Senior Debt (or a trustee or agent on behalf of any such holder). In the event that
the Trustee determines in good faith that further evidence is required with respect to the right of
any person as a holder of Senior Debt to participate in any payment or distribution pursuant to
this Article, the Trustee may request such person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Debt held by such person, the extent to
which such person is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such person under this Article, and if such evidence is not furnished,
the Trustee may defer any payment which it may be required to make for the benefit of such person
pursuant to the terms of this Indenture pending judicial determination as to the rights of such
person to receive such payment.

58

 

     The Trustee in its individual or any other capacity may hold Senior Debt with the same rights
it would have if it were not Trustee. The Paying Agent may do the same with like rights. The
Trustee shall be entitled to all the rights set forth in this Article 12 with respect to any Senior
Debt that may at any time be held by it, to the same extent as any other holder of such Senior
Debt; and nothing in Article 4 shall deprive the Trustee of any of its rights as such holder.

     Section 12.10. Distribution or Notice to Representative.

     Whenever a distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their representative (if any).

     Section 12.11. Article 12 Not to Prevent Events of Default or Limit Right to Accelerate.

     Nothing in this Article 12 shall prevent an Event of Default in accordance with Article 4 or
have any effect on the right of the Holders or the Trustee to accelerate the maturity of the
Securities or to exercise the rights and remedies in Article 4.

     Section 12.12. Trust Moneys and Make-Whole Payment Not Subordinated.

     Notwithstanding anything contained herein to the contrary, neither the Make-Whole Payment nor
payments from cash or the proceeds of non-callable U.S. Government Obligations held in trust under
Article 3 by the Trustee for the payment of principal of and interest on the Securities shall be
subordinated to the prior payment of any Senior Debt or subject to the restrictions set forth in
this Article 12, and none of the Holders shall be obligated to pay over any such amount to the
Company or any holder of Senior Debt or any other creditor of the Company.

     Section 12.13. Trustee Entitled to Rely.

     Upon any payment or distribution pursuant to this Article 12, the Trustee and the Holders
shall be entitled to conclusively rely (a) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 4.01(e) and Section
4.01(f) are pending, (b) upon a certificate of the liquidating trustee or agent or other Person
making such payment or distribution to the Trustee or to the Holders or (c) upon a certificate of
the representative of the holders of Senior Debt or, if there is no representative, the holders of
Senior Debt for the purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Debt and other Indebtedness of the Company, the amount thereof
or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 12.

     Section 12.14. Trustee’s Compensation Not Prejudiced.

     Nothing in this Article 12 will apply to amounts due to the Trustee pursuant to other Sections
in this Indenture.

     Section 12.15. Trustee to Effectuate Subordination.

     Each Holder by accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the subordination
between the Holders and the holders of Senior Debt as provided in this Article 12 and appoints the
Trustee as attorney-in-fact for any and all such purposes.

59

 

     Section 12.16. Trustee Not Fiduciary for Holders of Senior Debt.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and
shall not be liable to any such holders if it shall mistakenly pay over or distribute to Holders or
the Company or any other Person, money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 12 or otherwise. With respect to the holders of Senior Debt, the
Trustee undertakes to perform or to observe only such of its covenants or obligations as are
specifically set forth in this Article and no implied covenants or obligations with respect to
holders of Senior Debt shall be read into this Indenture against the Trustee.

     Section 12.17. Reliance by Holders of Senior Debt on Subordination Provisions.

     Each Holder by accepting a Security acknowledges and agrees that the foregoing subordination
provisions are, and are intended to be, an inducement and a consideration to each holder of any
Senior Debt, whether such Senior Debt was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior Debt and such
holder of such Senior Debt shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt.

ARTICLE 13. Option Of The Holder Upon A Change In Control

     Section 13.01. Right to Require Repurchase.

     In the event that a Change in Control shall occur, then each Holder shall have the right, at
the Holder’s option, but subject to the provisions of Section 13.02, to require the Company to
repurchase for cash, and upon the exercise of such right the Company shall repurchase, all of such
Holder’s Securities, or any portion of the principal amount thereof that is equal to U.S.$1,000 or
any greater integral multiple of U.S.$1,000, on the date (the “Repurchase Date”) that is fixed by
the Company at a cash purchase price equal to one hundred percent (100%) of the principal amount of
the Securities to be repurchased plus the Make-Whole Payment less any interest paid (the
“Repurchase Price”); provided, however, that installments of interest on Securities whose Stated
Maturity is on or prior to the Repurchase Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such on the relevant Record Date according to
their terms and the provisions of Section 2.11. The Repurchase Date will be determined by the
Company in the following manner: (i) the Company will give notice of the Change in Control as
contemplated in Section 13.02(a); (ii) the Holder will give notice of its election to exercise the
repurchase right as contemplated in Section 13.02(b); and (iii) the Company will make the
repurchase on a date that is no later than forty-five (45) days after the Holder has delivered the
notice provided in proviso (ii) above. Such right to require the repurchase of the Securities
shall not continue after a discharge of the Company from its obligations with respect to the
Securities in accordance with Article 3 unless a Change in Control shall have occurred prior to
such discharge. Whenever in this Indenture (including Sections 2.05, 4.01(b) and 4.08) there is a
reference, in any context, to the principal of any Security as of any time, such reference shall be
deemed to include reference to the Repurchase Price that has become and remains payable in respect
of such Security to the extent that such Repurchase Price is, was or would be so payable at such
time, and express mention of the Repurchase Price in any provision of this Indenture shall not be
construed as excluding the Repurchase Price in those provisions of this Indenture when such express
mention is not made.

60

 

     Section 13.02. Notices; Method of Exercising Repurchase Right, Etc.

     (a) On or before the thirtieth (30th) day after the occurrence of a Change in Control, the
Company or, at the request and expense of the Company on or before the thirtieth (30th) day after
such occurrence, the Trustee, shall give to all Holders of Securities, in the manner provided in
Section 1.06, notice (the “Repurchase Notice”) of the occurrence of the Change in Control and of
the repurchase right set forth herein arising as a result thereof. The Company shall be
responsible for preparing such Repurchase Notice and, in the event the Company shall deliver such
notice to the Holder, the Company shall also deliver a copy of such Repurchase Notice to the
Trustee.

     Each Repurchase Notice shall state:

     (1) the Repurchase Date,

     (2) the date by which the repurchase right must be exercised,

     (3) the Repurchase Price,

     (4) a description of the procedure that a Holder must follow to exercise a repurchase right,
and the place or places where such Securities are to be surrendered for payment of the Repurchase
Price and accrued interest, if any,

     (5) that on the Repurchase Date, the Repurchase Price, and accrued and unpaid interest, if
any, not included in the Repurchase Price, will become due and payable upon each such Security
designated by the Holder to be repurchased and that interest thereon shall cease to accrue on and
after said date,

     (6) the Conversion Rate then in effect, the date on which the right to convert the principal
amount of the Securities to be repurchased will terminate and the place or places where such
Securities may be surrendered for conversion, and

     (7) the place or places that the notice of election to repurchase shall be delivered, and the
form of such notice.

     No failure of the Company to give the foregoing notices or defect therein shall limit any
Holder’s right to exercise a repurchase right or affect the validity of the proceedings for the
repurchase of Securities.

     If any of the foregoing provisions or other provisions of this Article 13 are inconsistent
with applicable law, such law shall govern.

     (b) To exercise a repurchase right, a Holder shall deliver to the Trustee on or before the
thirtieth (30th) day (or such greater period as may be required by applicable law) after the date
of the Repurchase Notice (1) written notice of the Holder’s exercise of such right, which notice
shall set forth the name of the Holder, the principal amount of the Securities to be repurchased
(and, if any Security is to be repurchased in part, the serial number thereof, the portion of the
principal amount thereof to be repurchased and the name of the Person in which the portion thereof
to remain Outstanding after such repurchase is to be registered) and a statement that an election
to exercise the repurchase right is being made thereby, and (2) the Securities with

61

 

respect to which the repurchase right is being exercised. Such written notice shall be
irrevocable, except that the right of the Holder to convert the Securities with respect to which
the repurchase right is being exercised shall continue until the close of business on the Business
Day immediately preceding the Repurchase Date.

     (c) In the event a repurchase right shall be exercised in accordance with the terms hereof,
the Company shall pay or cause to be paid to the Trustee the Repurchase Price in cash for payment
to the Holder on the Repurchase Date together with accrued and unpaid interest to the Repurchase
Date payable with respect to the Securities as to which the purchase right has been exercised;
provided, however, that installments of interest that mature on or prior to the Repurchase Date
shall be payable in cash to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Regular Record Date.

     (d) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on
the Repurchase Date, the principal amount of such Security (or portion thereof, as the case may be)
shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date
at the rate then in effect per annum, and each Security shall remain convertible into Common Stock
until the principal of such Security (or portion thereof, as the case may be) shall have been paid
or duly provided for.

     (e) Any Security that is to be repurchased only in part shall be surrendered to the Trustee
(with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and make available for delivery to the Holder of such Security, a new Security or
Securities, containing identical terms and conditions, each in an authorized denomination in
aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal
of the Security so surrendered.

     (f) All Securities delivered for repurchase shall be delivered to the Trustee to be canceled
at the direction of the Company, which shall dispose of the same as provided in Section 2.13.
