     (a) The Notes shall be designated as “10.0% Guaranteed Senior Secured Convertible Notes due
2012”. The First Tranche of Notes in the initial aggregate principal amount of $20,000,000 upon
the execution of this Indenture, the Second Tranche of Notes up to an aggregate principal amount of
$30,000,000 upon any Second Tranche Issue Date, or from time to time thereafter, may be executed by
the Company and delivered to the Trustee or an Agent on its behalf for authentication, and the
Trustee shall thereupon authenticate and deliver said Notes in one or more series to or upon the
written order of the Company (as set forth in such Officer’s Certificate).

     (b) Notwithstanding that the Notes shall be issued at different times and may comprise
different series of Notes, all Notes issued under this Indenture shall vote and consent together on
all matters as one class and no series of Notes will have the right to vote or consent as a
separate class on any matter.

          Section 2.02.   Form of Notes. 

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

     (b) Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends, endorsements or changes as may be required to comply with any applicable law or
with any rule or regulation made pursuant thereto or with any rule or regulation of any securities
exchange or

22

 

automated quotation system on which the Notes may be listed, or to conform to usage, or to
indicate any special limitations or restrictions to which any particular Notes are subject.

          Section 2.03.   Date and Denomination of Notes; Payments of Interest. 

     (a) The Notes shall be issuable in registered form without coupons in denominations of
$100,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be
dated the date of its authentication and shall bear Interest from the date specified on the face of
the form of Note attached as Exhibit A hereto (or, in the case of Second Tranche Notes, shall bear
interest from the applicable Second Tranche Issue Date). Interest on the Notes shall be computed
on the basis of a 360-day year comprised of twelve 30-day months.

     (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Security
Register at the close of business on any record date with respect to any Interest Payment Date
shall be entitled to receive the Interest payable on such Interest Payment Date, except that the
Interest payable upon redemption or repurchase will be payable to the Person to whom principal is
payable pursuant to such redemption or repurchase (unless the redemption date or the repurchase
date, as the case may be, falls after a record date and on or prior to the corresponding Interest
Payment Date, in which case accrued and unpaid Interest to, but excluding, such redemption date or
repurchase date shall be payable on such Interest Payment Date to the holders of such Notes
registered as such on the applicable record date).

     (c) Notwithstanding the foregoing, if any Note (or portion thereof) is converted into Common
Stock during the period after a record date for the payment of Interest to, but excluding, the next
succeeding Interest Payment Date and such Note (or portion thereof) has been called or tendered for
redemption on a redemption date which occurs during such period, the Company shall not be required
to pay interest on such Interest Payment Date in respect of any such Note (or portion thereof).
Interest shall be payable at the office of the Company maintained by the Company for such purposes
in the City of Hong Kong, which shall initially be an office of the Trustee or principal Paying
Agent. The Company shall pay Interest on the Notes by (x) check mailed to the address of the
Person entitled thereto as it appears in the Security Register (or upon written notice, by wire
transfer in immediately available funds, if such Person is entitled to Interest on aggregate
principal in excess of $1,000,000) or (y) by transfer to an account maintained by such person in
Hong Kong or Singapore. In no circumstances shall any Paying Agent be obligated to make any
payment to Noteholders until such time as it has received sufficient funds from the Company. If an
Interest Payment Date is a Legal Holiday at the city in which the Corporate Trust Office of the
Trustee is located, payment may be made at that place on the next succeeding day that is not a
Legal Holiday, provided that Interest should be computed to the Interest Payment Date, provided
further that no interest shall accrue on such payment for the intervening period. The term “record
date” with respect to any Interest Payment Date shall mean the January 11, April 11, July 11 or
October 11 preceding the applicable January 25, April 25, July 25 or October 25 Interest Payment
Date, respectively.

President or any Vice President (whether or not designated by a number or numbers or word or words
added before or after the title “Vice President”) and attested by the manual or facsimile signature
of its Secretary or any of its Assistant Secretaries, its Treasurer or any of its Assistant
Treasurers (which may be printed,

23

 

engraved or otherwise reproduced thereon, by facsimile or otherwise) or a director of the
Board of Directors of the Company. Only such Notes as shall bear thereon a certificate of
authentication substantially in the form set forth on the form of Notes attached as Exhibit A
hereto upon a written order of the Company signed by an Officer (an “Authentication Order”),
manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided
by Section 16.10), shall be entitled to the benefits of this Indenture or be valid or obligatory
for any purpose. With respect to any Second Tranche Notes issued after the First Tranche Issue
Date (except for Notes authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, other Notes pursuant to the other provisions of this Indenture), there shall be
set forth in an Authentication Order prior to the issuance of such Notes (i) the aggregate
principal amount of such Second Tranche Notes to be authenticated and delivered under this
Indenture; and (ii) the issuance date of such Second Tranche Notes, including the date from which
Interest on such Notes shall accrue. Such certificate by the Trustee (or such an authenticating
agent) upon any Note executed by the Company shall be conclusive evidence that the Note so
authenticated has been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture. The Trustee shall have the right to decline to authenticate and
deliver any Notes under this Indenture unless and until it receives an Authentication Order from
the Company.

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

          Section 2.05.   Transfer and Exchange

     (a) When Notes are presented to the Registrar or a co-Registrar with a request to register the
transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other
authorized denominations, the Registrar or co-Registrar shall promptly register the transfer or
make the exchange as requested if its requirements for such transaction are met; provided, however,
that the Notes surrendered for transfer (including any transfer in connection with an exchange of
Notes) shall be accompanied a certificate substantially in the form of Exhibit C-1 and a
transfer instrument substantially in the form of Exhibit C-2, in each case duly executed by
the holder thereof or his or her attorney duly authorized in writing. The Company undertakes to
deliver to, or to the order of, the Registrar sufficient numbers of duly executed Notes together
with Authentication Orders to enable the Trustee and the Registrar to comply with their
obligations under this Indenture. Such transfers and exchanges shall be made free of charge to the
holder and the beneficial owners of the Notes, except that (i) the Registrar may require payment of
a sum sufficient to cover any tax or other government charge payable in connection therewith and
(ii) a Person receiving Notes must bear the cost of insurance, postage, transportation and the like
in the event that such Person does not receive such Notes in person at the offices of a Registrar.

     (b) The Registrar shall cause all Notes delivered to it and held by it hereunder to be
maintained in safe custody in accordance with this Section 2.05.

     (c) The Security Register shall be in written form in the English language and shall include a
record of the certificate number of each Note that has been issued, and shall show the amount of
such Notes, the date of issue, all subsequent transfers and changes in ownership in respect thereof
and the names, tax

24

 

identifying numbers (if relevant to a specific holder), addresses of the holders of the Notes
and any payment instructions with respect thereto (if different from a holder’s registered
address).

     (d) The Registrar shall at all reasonable times during office hours make the Security Register
available to the Trustee, the Paying Agent, the Company and the holders of such Notes or any person
authorized by the Company in writing for inspection and for taking of copies thereof or extracts
therefrom, and at the expense of the Company, the Registrar shall deliver to such persons all lists
of holders of such Notes, their addresses, amounts of such holdings and other details as they may
request.

     (e) The Registrar shall handle all requests for the registration of transfer, or exchange,
repurchase or conversion of Notes and receive certificates for the Notes deposited with the
transfer agent for transfer, or exchange, repurchase or conversion, and in doing so, shall ensure
that every Note presented or surrendered for registration of transfer, or exchange, repurchase or
conversion, (if so required by the Company, the Trustee, the Paying Agent or the Registrar) be duly
endorsed by, or be accompanied by a written instrument or instruments of transfer (in form
satisfactory to the Company and the Registrar) duly executed by the holder thereof or by such
holder’s attorney duly authorized in writing.

     (f) Neither the Company nor the Trustee nor any Registrar shall be required to exchange or
register a transfer of (a) any Notes or portions thereof surrendered for conversion pursuant to
Article 14 or (b) any Notes or portions thereof tendered for purchase pursuant to
Section 3.02 (and not withdrawn).

     (g) Until the expiration of the holding period applicable to sales thereof under Rule 144
under the Securities Act (or any successor provision), any certificate evidencing such Note (and
all securities issued in exchange therefor or substitution thereof, other than Common Stock, if
any, issued upon conversion thereof, which shall bear the legend set forth in Exhibit D, if
applicable) shall bear a legend set forth in Exhibit A, unless such Note has been sold
pursuant to a registration statement that has been declared effective under the Securities Act (and
which continues to be effective at the time of such transfer) or pursuant to Rule 144 under the
Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in
writing, with written notice thereof to the Trustee.

     (h) Any stock certificate representing Common Stock issued upon conversion of such Note shall
bear a legend substantially in the form of Exhibit D.

     (i) The Trustee and the Registrar shall be entitled to treat a telephone, telex or facsimile
communication from a person purporting to be (and who the Trustee or the Registrar believe in good
faith to be) the authorized representative of the Company, named in a list furnished to the Trustee
and the Registrar from time to time, as sufficient instructions and authority of the Company for
the Trustee and the Registrar to act in accordance with this Section.

     (j) Title to the Notes shall pass by upon recordation of transfer or exchange in the Security
Registrar.

          Section 2.06.   Mutilated, Destroyed, Lost or Stolen Notes. 

     In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its written request the Trustee or an authenticating agent
appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a
number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or
in lieu of and in

25

 

substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a
substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent, such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or connected with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company,
to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of
the destruction, loss or theft of such Note and of the ownership thereof.

     Following receipt by the Trustee or such authenticating agent, as the case may be, of
satisfactory security or indemnity and evidence, as described in the preceding paragraph and an
Authentication Order from the Company, the Trustee or such authenticating agent may authenticate
any such substituted Note and make available for delivery such Note. Upon the issuance of any
substituted Note, the Company or the Trustee, as the case may be, may require the payment by the
holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be
imposed in relation thereto and any other expenses connected therewith. In case any Note which has
matured or is about to mature or has been called for redemption or has been tendered for repurchase
upon a Termination of Trading (and not withdrawn) or is to be converted into Common Stock shall
become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute
Note, pay or authorize the payment of or convert or authorize the conversion of the same (without
surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for
such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or in connection with such
substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to
the Company, the Trustee and, if applicable, any paying agent or conversion agent evidence to their
satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

     Every substitute Note issued pursuant to the provisions of this Section by virtue of the fact
that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and
shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in)
this Indenture equally and proportionately with any and all other Notes duly issued hereunder. If,
after the delivery of such replacement Note, a protected purchaser of the original Note in lieu of
which such replacement Note was issued presents for payment, registration or conversion of such
original Note, the Trustee shall be entitled to recover such replacement Note from the Person to
whom it was delivered or any Person taking therefrom, except a protected purchaser, and shall be
entitled to recover upon the security or indemnity provided therefor to the extent of any loss,
damage, cost or expense incurred by the Company, the Trustee and any authenticating agent in
connection therewith.

          Section 2.07.   [Reserved]

          Section 2.08.   Cancellation of Notes.

     All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange
or registration of transfer shall, if surrendered to the Company or any paying agent or any
Registrar or any conversion agent, be surrendered to the Trustee and promptly cancelled by it, or,
if surrendered to the Trustee, shall be promptly cancelled by it, and no Notes shall be issued in
lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee
shall dispose of such cancelled Notes in accordance with its customary procedures. If the Company
shall acquire any of the Notes, such acquisition

26

 

shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented
by such Notes unless and until the same are delivered to the Trustee for cancellation.

          Section 2.09.   Defaulted Interest. 

     If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are holders on a subsequent special record date, in each case at the
rate provided in the Notes and in Section 4.01.

     The Company shall notify the Trustee, in writing, at least 10 days prior to the proposed
payment date of the amount of defaulted interest proposed to be paid on each Note and any Default
Interest calculated and payable pursuant to Section 4.01, and the date of the proposed payment of
such amounts. The Company shall fix or cause to be fixed each such special record date and payment
date; provided that no such special record date shall be less than 10 days prior to the related
Interest Payment Date for such amounts. At least 15 days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name and at the expense of
the Company) shall mail or cause to be mailed to holders a notice that states the special record
date, the related Interest Payment Date and the amount of such interest to be paid.

          Section 2.10.   Holder Lists. 

     The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of the holders. If the Trustee is not the
Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on January
11 and July 11 of each year a listing of holders dated within ten days of the date on which the
list is furnished and at such other times as the Trustee may request in writing a list, in such
form and as of such date as the Trustee may reasonably require, of the names and addresses of
holders.

take such action; provided that if such deposit is made on the due date, such deposit shall be
received by the paying agent by 10:00 a.m. Hong Kong time, on such date.

that it be remedied and stating that such notice is a “Notice of Default”;

     then, and in each and every such case (other than an Event of Default specified in Section
6.01(f) or 6.01(g)), unless the principal of all of the Notes shall have already become
due and payable, either the Trustee or the holders of not less than twenty-five percent (25%) in
aggregate principal amount of the Notes then outstanding hereunder determined in accordance with
Section 13.04, by notice in writing to the Company (and to the Trustee if given by

of the Notes shall have been so declared due and payable, and before any judgment or decree for the
payment of the monies due shall have been obtained or entered as hereinafter provided, (i) the
Company shall pay or

41

 

shall deposit with the Trustee a sum sufficient to pay all matured installments of Interest

the extent that payment of such interest is enforceable under applicable law) and on such principal
(and all other amounts) at the rate borne by the Notes, to the date of such payment or deposit) and
amounts due to the Trustee pursuant to Section 7.06, (ii) if any and all defaults under
this Indenture, other than the nonpayment of principal of (and all other amounts) and accrued
Interest on Notes which shall have become due by acceleration, shall have been cured or waived
pursuant to Section 6.08, then and in every such case the holders of a majority in
aggregate principal amount of the Notes then outstanding, by written notice to the Company and to
the Trustee, may waive all Defaults or Events of Default and rescind and annul such declaration and
its consequences; but no such waiver or rescission and annulment shall extend to or shall affect
any subsequent Default or Event of Default, or shall impair any right consequent thereon. The
Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware
thereof, of any Event of Default.

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

          Section 6.02.   Payments of Notes on Default; Suit Therefor. 

     The Company covenants that (a) in case default shall be made in the payment of any installment
of Interest upon any of the Notes as and when the same shall become due and payable, and such
default shall have continued for a period of thirty (30) days, or (b) in case default shall be made
in the payment of the principal of any of the Notes as and when the same shall have become due and
payable, whether at maturity of the Notes or in connection with any redemption or repurchase, by or
under this Indenture by declaration or otherwise, then, upon demand of the Trustee, the Company
will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then
shall have become due and payable on all such Notes for principal, Interest and all other amounts
due, as the case may be, with interest upon the overdue principal and all other amounts due and (to
the extent that payment of such interest is enforceable under applicable law) upon the overdue
installments of Interest at the rate borne by the Notes, plus 5% and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of collection, including
compensation to the Trustee, its agents, attorneys and counsel, and all other amounts due the
Trustee under Section 7.06. Until such demand by the Trustee, the Company may pay the
principal of, all other amounts payable on, and Interest on the Notes to the registered holders,
whether or not the Notes are overdue.

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

     In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company or any other obligor on the Notes under any Bankruptcy Law, or in case a receiver, assignee
or

42

 

trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall
have been appointed for or taken possession of the Company or such other obligor, the property of
the Company or such other obligor, or in the case of any other judicial proceedings relative to the
Company or such other obligor upon the Notes, or to the creditors or property of the Company or
such other obligor, the Trustee, irrespective of whether the principal of the Notes or other
amounts shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this
Section, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file
and prove a claim or claims for the whole amount of principal, Interest and all such other amounts
owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such
proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the
Company or any other obligor on the Notes, its or their creditors, or its or their property, and to
collect and receive any monies or other property payable or deliverable on any such claims, and to
distribute the same after the deduction of any amounts due the Trustee under Section 7.06,
and to take any other action with respect to such claims, including participating as a member of
any official committee of creditors, as it reasonably deems necessary or advisable, and, unless
prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized by each of the
Noteholders to make such payments to the Trustee, and, in the event that the Trustee shall consent
to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it
for compensation, expenses, advances and disbursements, including counsel fees and expenses
incurred by it up to the date of such distribution. To the extent that such payment of
compensation, expenses, advances and disbursements out of the estate in any such proceedings shall
be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property which the holders
of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any
plan of reorganization or arrangement or otherwise.

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

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

          Section 6.03.   Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy
to collect the payment of principal, premium, if any, and Interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture. In addition, if an Event of Default
occurs and is continuing, the Trustee may, upon request of Noteholders of at least 25% of the
aggregate principal amount of the Notes then outstanding, instruct the Collateral Agent to
foreclose on the Collateral in accordance with the terms of the Security Documents and take such
further action on behalf of the Noteholders with respect to the Collateral as the Trustee deems
appropriate.

43

 

     The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding.

          Section 6.04.   Application of Monies Collected by Trustee. 

     Any monies or property collected by the Trustee pursuant to this Article shall be applied in
the order following, at the date or dates fixed by the Trustee for the distribution of such monies

only partially paid, or (ii) upon surrender thereof, if fully paid.

Interest and all other amounts, with Interest on the overdue principal, such other amounts
and (to the extent that such Interest has been collected by the Trustee) upon overdue
installments of Interest at the rate specified in the Notes, and in case such monies shall
be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to
the payment of such principal, Interest and such other amounts without preference or
priority of principal over Interest, or of Interest over principal, or of any installment of
Interest over any other installment of Interest, or of any Note over any other Note, ratably

     FOURTH: To the payment of the remainder, if any, to the Company or the Guarantors or
to whomever may be lawfully entitled thereto.

     The holders of a majority in aggregate principal outstanding amount of the Notes may direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee or
any Collateral Agent or of exercising any trust or power conferred on the Trustee or any Collateral
Agent; provided that the Trustee or Collateral Agent may refuse to follow any direction that
conflicts with law or this Indenture or the other Transaction Documents or, subject to Section
7.01., that the Trustee or such Collateral Agent determines is prejudicial to the rights of other
Noteholders. Each of the Trustee and the Collateral Agent shall have no liability for any action
taken or omitted to be taken by it in good faith in accordance with the direction of the holders of
not less than a

44

 

majority in principal amount of the Notes at
 the time outstanding relating to the time, method, or place of conducting any proceeding for
any remedy available to such Trustee or Collateral Agent, or exercising any trust or power
conferred upon the Trustee or Collateral Agent, under this Indenture or any other Transaction
Document.

this Indenture to institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless (a) such holder
previously shall have given to the Trustee written notice of an Event of Default and of the
continuance thereof, as hereinbefore provided, (b) the holders of not less than twenty-five percent
(25%) in aggregate principal amount of the Notes then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such security or indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby in the form satisfactory to the
Trustee, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of
indemnity shall have neglected or refused to institute any such action, suit or proceeding and no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 6.08; it being understood and intended, and being expressly covenanted by the taker
and holder of every Note with every other taker and holder and the Trustee, that no one or more
holders of Notes shall have any right in any manner whatever by virtue of or by reference to any
provision of this Indenture to affect, disturb or prejudice the rights of any other holder of
Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to
enforce any right under this Indenture, except in the manner herein provided and for the equal,
ratable and common benefit of all holders of Notes (except as otherwise provided herein); provided
that nothing contained herein or in the other Transaction Documents shall limit the rights of
holders holding not less than sixty-six and two-thirds percent (66.66%) of the aggregate principal
amount of the Notes then outstanding from instituting any suit, action or proceeding in equity or
at law upon, under or with respect to this Indenture, the Notes or the other Transaction Documents
or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or
for any other remedy hereunder or thereunder. For the protection and enforcement of this Section
each and every Noteholder and the Trustee shall be entitled to such relief as can be given either
at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any holder of any Note to receive payment of the principal of (including the purchase price upon
an Offer to Purchase or the repurchase price, in each case pursuant to Article 3) and
accrued Interest on such Note, on or after the respective due dates expressed in such Note or in
the event of an Offer to Purchase or a repurchase, as the case may be, or to institute suit for the
enforcement of any such payment on or after such respective dates against the Company shall not be
impaired or affected without the consent of such holder.

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

          Section 6.06.   Proceedings by Trustee. 

     In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are
necessary to protect and enforce any of such rights, either by suit in equity or by action at law
or by proceeding in bankruptcy or

45

 

 otherwise, whether for the specific enforcement of any covenant
or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal
or equitable right vested in the Trustee by this Indenture or by law.

          Section 6.07.   Remedies Cumulative and Continuing. 

     Except as provided in Section 2.06, all powers and remedies given by this Article to
the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any thereof or of any other powers and remedies available to the Trustee or the
holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture, and no delay or omission of
the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any
Default or Event of Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or any acquiescence therein, and,
subject to the provisions of Section 6.05, every power and remedy given by this Article or
by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Noteholders.

          Section 6.08.   Direction of Proceedings and Waiver of Defaults by Majority of Holders of
the Notes. 

     The holders of a majority in aggregate principal amount of the Notes at the time outstanding
determined in accordance with Section 13.04 shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or exercising any
trust or power conferred on the Trustee; provided that (a) such direction shall not be in conflict
with any rule of law or with this Indenture, (b) the Trustee may take any other action which is not
inconsistent with such direction, (c) the Trustee may decline to take any action that would benefit
some Noteholder to the detriment of other Noteholders and (d) the Trustee may decline to take any
action that would involve the Trustee in personal liability. Subject to Section 6.01, the
holders of a majority in aggregate principal amount of the Notes at the time outstanding determined
in accordance with Section 13.04 may, on behalf of the holders of all of the Notes, waive
any past Default or Event of Default hereunder and its consequences except (i) a default in the
payment of Interest on, or the principal of, or any Repurchase Amount in respect of, the Notes,
(ii) a failure by the Company to convert any Notes into Common Stock, (iii) a default in the
payment of the Purchase Price pursuant to Section 3.02, or (iv) a default in respect of a
covenant or provisions hereof which under Article 8 cannot be modified or amended without
the consent of the holders of each or all of the Notes then outstanding or affected thereby. Upon
any such waiver, the Company, the Trustee and the holders of the Notes shall be restored to their
former positions and rights hereunder; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event
of Default hereunder shall have been waived as permitted by this Section, said Default or Event of
Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to
be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereon.

          Section 6.09.   Notice of Default. 

     If the Trustee receives notice of any Default or Event of Default from the Company, the
Trustee shall notify to all Noteholders, as the names and addresses of such holders appear upon the
Security Register, Notice of the Default or Event of Default within 90 days after it occurs, unless
the Default or Event of Default shall have been cured or waived before the giving of such notice;
provided that except in

46

 

 the case of default in the payment of the principal of or Interest on any
of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determines that the withholding of such notice is
in the interests of the Noteholders.

          Section 6.10.   Undertaking to Pay Costs. 

     All parties to this Indenture agree, and each holder of any Note by his acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or defenses made by such
party litigant; provided that the provisions of this Section (to the extent permitted by law) shall
not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group
of Noteholders, holding in the aggregate more than ten percent in principal amount of the Notes at
the time outstanding determined in accordance with Section 13.04, or to any suit instituted
by any Noteholder for the enforcement of the payment of the principal of or Interest on (or any
Repurchase Amount or other amount in respect of) any Note on or after the due date expressed in
such Note or to any suit for the enforcement of the right to convert any Note in accordance with
the provisions of Article 15.

ARTICLE 7

THE TRUSTEE

          Section 7.01.   Duties and Responsibilities of Trustee. 

     The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events
of Default which may have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture. Whether or not expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or affording protection to the
Trustee is subject to this Article. The rights and protections provided to the Trustee in this
Article shall also apply to the Agents. However, the duties and obligations of the Trustee and the
Agents hereunder are several and not joint. In case an Event of Default has occurred (which has not
been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person’s own affairs.

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

     (a) prior to the occurrence of an Event of Default and after the curing or waiving of
all Events of Default which may have occurred:

     (i) the duties and obligations of the Trustee shall be determined solely by the
express provisions of this Indenture, and the Trustee shall not be liable except for
the performance of such duties and obligations as are specifically set forth in this
Indenture

47

 

and no implied covenants, duties or obligations shall be read into this
Indenture against the Trustee; and

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

     (b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless the Trustee was grossly negligent in
ascertaining the pertinent facts;

     (c) the Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the written direction of the holders of not
less than a majority in principal amount of the Notes at the time outstanding determined as
provided in Section 13.04 relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power
conferred upon the Trustee under this Indenture;

     (d) whether or not therein provided, every provision of this Indenture relating to the
conduct or affecting the liability of, or affording protection to, the Trustee shall be
subject to the provisions of this Section 7.01;

     (e) the Trustee shall not be liable in respect of any payment (as to the correctness of
amount, entitlement to receive or any other matters relating to payment) or notice effected
by the Company or any paying agent or any records maintained by any co-registrar with
respect to the Notes;

     (f) if any party fails to deliver a notice relating to an event the fact of which,
pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may
conclusively rely on its failure to receive such notice as reason to act as if no such event
occurred; and

     (g) the Trustee shall not be deemed to have knowledge of any Default or Event of
Default hereunder unless a Responsible Officer of the Trustee at the Corporate Trust Office
shall have been notified in writing of such Default or Event of Default by the Company or
the holders of at least 25% in aggregate principal amount of the Notes.

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

Notwithstanding anything to the contrary contained in this Indenture, none of the Agents shall be
obliged to act or omit to act in accordance with any instruction, direction or request delivered to
them by the Company

48

 

unless such instruction, direction or request is delivered to such Agents
according to the provisions under
this Indenture in writing. Each of the Agents may, in connection with its services hereunder rely
upon the terms of any notice, communication or other document believed by it to be genuine.

          Section 7.02.   Rights of Trustee. 

          Subject to its duties and responsibilities under Section 7.01:

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

     (b) Any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof
be herein specifically prescribed); and any resolution of the Board of Directors may be
evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant
Secretary of the Company; the Trustee shall be entitled to accept such certificate as
sufficient and conclusive evidence of the fulfillment of the applicable conditions
precedent, in which event it shall be conclusive and binding on the Noteholders.

     (c) The Trustee may consult with counsel of its own selection (with such reasonable,
out-of-pocket expenses of such counsel reimbursable pursuant to Section 7.06) and
any advice or opinion of counsel shall be full and complete authorization and protection in
respect of any action taken or omitted by it hereunder in good faith and in accordance with
such advice or opinion of counsel; the Trustee shall be entitled to accept such opinion as
sufficient and conclusive evidence of the fulfillment of the applicable conditions
precedent, in which event it shall be conclusive and binding on the Noteholders.

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

     (e) The Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture or other paper or document, but the
Trustee may make such further inquiry or investigation into such facts or matters as it may
see fit, and, if the Trustee shall determine to make such further inquiry or investigation,
it shall be entitled to examine the books, records and premises of the Company, personally
or by agent or attorney at the expense of the Company, and shall incur no liability of any
kind by reason of such inquiry or investigation.

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

49

 

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

     (h) 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.

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

     (j) Any permissive right or authority granted to the Trustee shall not be construed as
a mandatory duty.

     (k) The Trustee shall not be required to give any bond or surety in respect of the
performance of its powers and duties hereunder.

     (l) The Trustee shall have no duty to inquire as to the performance of the Company’s
covenants herein.

     (m) Neither the Trustee nor any clearing system through which the Notes are traded
shall have any obligation or duty to monitor, determine or inquire as to compliance, and
shall not be responsible or liable for compliance, with restrictions on transfer, exchange,
redemption, purchase or repurchase, as applicable, of minimum denominations imposed
hereunder or under applicable law or regulation with respect of any transfer, exchange,
redemption, purchase or repurchase, as applicable, of interest in any Note.

     (n) In the event the Trustee receives inconsistent or conflicting requests and
indemnity from two or more groups of Noteholders, each representing less than a majority in
aggregate principal amount of the Notes then outstanding, pursuant to the provisions of this
Indenture, the Trustee, in its sole discretion, may determine what action, if any, will be
taken.

     (o) The Trustee is entitled to enter into business transactions with the Company, its
Affiliates or any entity related thereto without accounting for any profit. However, the
Trustee must comply with Section 7.07.

     (p) In connection with the exercise of its functions (including but not limited to
those in relation to any proposed modification, authorization, waiver or substitution), the
Trustee will have regard to the interests of the Noteholders as a class, and will not have
regard to the consequences of such exercise for individual Noteholders. The Trustee will not
be entitled to require, nor will any Noteholder be entitled to claim, from the Company or
any Guarantor, any indemnification or payment in respect of any tax consequences of any such
exercise upon individual Noteholders.

50

 

     (q) The Trustee may refrain from taking any action in any jurisdiction if the taking of
such action in that jurisdiction would, in its opinion based upon legal advice in the
relevant jurisdiction, be contrary to any law of that jurisdiction or, to the extent
applicable, of the State of New York. Furthermore, the Trustee may also refrain from taking
such action if it would otherwise render it liable to any person in that jurisdiction or the
State of New York or if, in its opinion based upon such legal advice, it would not have the
power to do the relevant thing in that jurisdiction by virtue of any applicable law in that
jurisdiction or in the State of New York or if it is determined by any court or other
competent authority in that jurisdiction or in the State of New York that it does not have
such power.

     (r) The Trustee shall not be responsible or liable for special, indirect, punitive, or
consequential damages or loss of any kind whatsoever (including, but not limited to, loss of
profit) irrespective of whether the Trustee has been advised of the likelihood of such loss
or damage and regardless of the form of action.

     Notwithstanding any provision herein to the contrary, the Trustee shall not be obligated to
take any action with respect to an Event of Default pursuant to Section 6.01(j) unless it
has been first notified to do so in writing by the holders of at least 25% in aggregate principal
amount of the outstanding Notes.

          Section 7.03.   No Responsibility for Recitals, Etc. 

     The recitals, statements, representations and warranties contained herein and in the Notes
(except in the Trustee’s certificate of authentication) shall be taken as the statements of the
Company, and the Trustee assumes no responsibility for the accuracy or correctness of the same or
for the execution, legality, effectiveness, adequacy, genuineness, validity or enforceability or
admissibility in evidence of any such agreement or other document or any security constituted
thereby or pursuant thereto. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or
application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

          Section 7.04.   Trustee, Paying Agents, Conversion Agents, Collateral Agents or Registrar
May Own Notes. 

     The Trustee, any paying agent, any conversion agent, Collateral Agent or Registrar, in its
individual or any other capacity, may become the owner or pledgee of Notes with the same rights it
would have if it were not Trustee, paying agent, conversion agent, Collateral Agent or Registrar.

          Section 7.05.   Monies to Be Held in Trust. 

     Subject to the provisions of Section 12.04, all monies received by the Trustee or any
Agent shall, until used or applied as herein provided, be held in trust for the purposes for which
they were received. Money held by the Trustee or any Agent in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee and the Agents shall
be under no liability for interest on any money received by it hereunder except as may be agreed in
writing from time to time by the Company and the Trustee or the applicable
Agent(s).

          Section 7.06.   Compensation and Expenses of Trustee. 

51

 

     The Company and each Guarantor, jointly and severally, covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) as mutually agreed to from time to
time in writing between the Company and the Trustee, and the Company and each Guarantor, jointly
and severally, will pay or reimburse the Trustee upon its request for all reasonable, out-of-pocket
expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the
provisions of this Indenture and the Security Documents (including the compensation and the
expenses and disbursements of its counsel and of all Persons not regularly in its employ), except
any such expense, disbursement or advance as shall be determined to have been caused by its own
gross negligence, bad faith or willful misconduct. If an Event of Default shall have occurred or
if the Trustee finds it expedient or necessary or is requested by the Company to undertake duties
which the Trustee believes to be of an exceptional nature or is otherwise outside the scope of the
Trustee’s normal duties under this Indenture, the Company will pay such additional remuneration as
the Trustee and the Company may agree in writing. When the Trustee incurs fees, expenses or
renders services in connection with an Event of Default, the fees and expenses (including such
charges and expenses incurred by its counsel and all applicable taxes) and the compensation for the
services are intended to constitute expenses of administration under any Bankruptcy Law. All
rights, protections and benefits of the Trustee shall be extended to the Trustee acting as an Agent
with respect thereto. The Company and each Guarantor, jointly and severally, covenants to indemnify
and hold harmless the Trustee and any predecessor Trustee (or any officer, director, agent or
employee of the Trustee) in any capacity under this Indenture and the Security Documents (which,
for the avoidance of doubt, includes its duties as Collateral Agent, paying agent, conversion agent
or Registrar) and its agents and any authenticating agent for any and all loss, liability, damage,
claim or expense, including taxes (other than taxes based on the income of the Trustee) incurred
without gross negligence, bad faith or willful misconduct on the part of the Trustee or such
officers, directors, employees and agents or authenticating agent, as the case may be, and arising
out of or in connection with the acceptance or administration of this trust, its duties under this
Indenture, the Notes, the Guarantee and the Security Documents, including the costs and expenses
arising under this Indenture, the Notes, the Guarantee and the Security Documents and defending
themselves against any claim (whether asserted by the Company, any holder or any other Person) or
liability in connection with the exercise or performance of any of its powers or duties hereunder.
The obligations of the Company under this Section to compensate or indemnify the Trustee and to pay
or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior
to that of the Notes upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the benefit of the holders of particular Notes. The obligation of the
Company under this Section shall survive the satisfaction and discharge of this Indenture pursuant
to Article 12, the termination of this Indenture and the Security Documents, the
resignation or removal of the Trustee or payment in full of the Notes through the expiration of the
applicable statute of limitations.

     To secure the Company’s payment obligations in this Section, the Trustee shall have a Lien
prior to the Notes on all money or property held or collected by the Trustee, except that held in
trust to pay principal, premium, if any, and interest on particular Notes. Such Lien shall survive
the satisfaction and discharge of this Indenture pursuant to Article 12, the termination of
this Indenture and the Security Documents, the resignation or removal of the Trustee or payment in
full of the Notes through the expiration of the applicable statute of limitations.

     When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(f) or (g) with respect to the
Company occurs, the

52

 

expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws.

          Section 7.07.   Eligibility and Disqualification of Trustee. 

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

          Section 7.08.   Resignation or Removal of Trustee.

     (a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and to the holders of Notes. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and
one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment sixty (60) days after the mailing of such notice of resignation to the
Noteholders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the
Noteholders, petition, at the expense of the Company, any court of competent jurisdiction for the
appointment of a successor trustee, or, any Noteholder who has been a bona fide holder of a Note or
Notes for at least six (6) months may, subject to the provisions of Section 6.10, on behalf
of himself and all others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

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

     (i) the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.09 and shall fail to resign after written request therefor by the Company
or by any such Noteholder; or

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

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of its Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 6.10, any Noteholder who has been a bona fide holder
of a Note or Notes for at least six (6) months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee; provided that if no successor Trustee shall have been appointed
and have accepted appointment sixty (60) days after either the Company or such Noteholder has
removed the Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of
the Company, any court of competent jurisdiction for an appointment of a successor trustee.

53

 

Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove
the Trustee and appoint a successor trustee.

     (c) The holders of a majority in aggregate principal amount of the Notes at the time
outstanding may at any time remove the Trustee and nominate a successor trustee which shall be
deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of
such nomination, the Company objects thereto, in which case the Trustee so removed or any
Noteholder, or, if such Trustee so removed or any Noteholder fails to act, the Company, upon the
terms and conditions and otherwise as in Section 7.08(a) provided, may petition any court
of competent jurisdiction for an appointment of a successor trustee.

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

     (e) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

          Section 7.09.   Acceptance by Successor Trustee. 

     Any successor trustee appointed as provided in Section 7.08 shall execute, acknowledge
and deliver to the Company and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like
effect as if originally named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount
then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee so ceasing to act.
Upon request of any such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property
and funds held or collected by such trustee as such, except for funds held in trust for the benefit
of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of
Section 7.06.

     No successor trustee shall accept appointment as provided in this Section unless, at the time
of such acceptance, such successor trustee shall be eligible under the provisions of Section
7.07.

     Upon acceptance of appointment by a successor trustee as provided in this Section, the Company
(or the former trustee, upon the written direction of the Company and at the expense of the
Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the
holders of Notes at their addresses as they shall appear on the Security Register. If the Company
fails to mail such notice within ten (10) days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

          Section 7.10.   Succession by Merger. 

     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

54

 

business of the Trustee (including any trust created by this Indenture), shall be the
successor to the Trustee hereunder without the execution or filing of any paper or any further act
on the part of any of the parties hereto, provided that in the case of any corporation succeeding
to all or substantially all of the corporate trust business of the Trustee, such corporation shall
be eligible under the provisions of Section 7.07. The Trustee shall provide the Company
with a written notice within thirty (30) days after the closing of such merger, conversion or
consolidation.

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

          Section 7.11.   Trustee’s Application for Instructions from the Company. 

     Any application by the Trustee for written instructions from the Company (other than with
regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the
rights of the holders of the Notes under this Indenture) may, at the option of the Trustee, set
forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and
the date on and/or after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with
a proposal included in such application on or after the date specified in such application (which
date shall not be less than three (3) Business Days after the date any Officer of the Company
actually receives such application, unless any such Officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in the case of an
omission), the Trustee shall have received written instructions in response to such application
specifying the action to be taken or omitted.

          Section 7.12.   Certain Provisions.

     Each Noteholder by accepting a Note authorizes and directs on his or her behalf the Trustee to
enter into and to take such actions and to make such acknowledgements as are set forth in this
Indenture or other documents entered into in connection therewith.

     The Trustee shall not be responsible for the legality, validity, effectiveness, suitability,
adequacy or enforceability of any of the Security Documents or any obligation or rights created or
purported to be created thereby or pursuant thereto or any security or the priority thereof
constituted or purported to be constituted thereby or pursuant thereto, nor shall it be responsible
or liable to any person because of any invalidity of any provision of such documents or the
unenforceability thereof, whether arising from statute, law or decision of any court. The Trustee
shall be under no obligation to monitor or supervise the functions of the Collateral Agent under
the Security Documents and shall be entitled to assume that the Collateral Agent is properly
performing its functions and obligations thereunder and the Trustee shall not be responsible for
any diminution in the value of or loss occasioned to the assets subject thereto by reason of the
act or omission by the Collateral Agent in relation to its functions thereunder. The Trustee shall
have no

55

 

responsibility whatsoever to the Company, any Guarantor or any Noteholder as regards any
deficiency which might arise because the Trustee is subject to any tax in respect of the Security
Documents, the security created thereby or any part thereof or any income therefrom or any proceeds
thereof.

          Section 7.13.   Discretion of the Trustee.

     Whenever in this Indenture or by law, the Trustee shall have discretion or permissive power it
may decline to exercise the same in the absence of approval by the Noteholders.

          Section 7.14.   Force Majeure.

     Notwithstanding anything to the contrary in this Indenture or in any other transaction
document, the Trustee shall not in any event be liable for any failure or delay in the performance
of its obligations hereunder if it is prevented from so performing its obligations by any existing
or future law or regulation, any existing or future act of governmental authority, Act of God,
flood, war whether declared or undeclared, terrorism, riot, rebellion, civil commotion, strike,
lockout, other industrial action, general failure of electricity or other supply, aircraft
collision, technical failure, accidental or mechanical or electrical breakdown, computer failure or
failure of any money transmission system or any reason which is beyond the control of the Trustee.

          Section 7.15.   Acceleration.

     The Trustee shall not be obliged to declare the Notes immediately due and payable under the
Indenture unless it has received from Noteholders such indemnity and security to its reasonable
satisfaction in respect of all costs, claims and liabilities which it may as a consequence thereof
in its reasonable opinion render itself, or have rendered itself, liable (excluding any costs,
claims or liabilities to the extent arising from the Trustee’s gross negligence or willful
misconduct).

          Section 7.16.   Error of Judgment.

     The Trustee shall not be liable for any error of judgment by any officer or employee of the
Trustee assigned by the Trustee to administer its corporate trust matters (in each case other than
arising from the Trustee’s gross negligence or willful misconduct)

          Section 7.17.   Event of Default.

     If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture, and use the same degree of care and skill in its
exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such
Person’s own affairs subject to Articles 6 and 7 hereof.

ARTICLE 8

          Section 8.01.   Supplemental Indentures Without Consent of Noteholders.

restriction or condition, such supplemental indenture may provide for a particular period of

the remedies available to the Trustee upon such Default;

     (e) to provide for the issuance under this Indenture of Notes in coupon form (including

of Directors certified by its Secretary or Assistant Secretary authorizing the execution of any
supplemental indenture (in form satisfactory to the Trustee), the Trustee is hereby authorized to
join with the Company in the execution of any such supplemental indenture, to make any further
appropriate agreements and stipulations that may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder; provided that the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section may be executed by the
Company and the Trustee without the consent of the holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 8.02.

          Section 8.02.   Supplemental Indenture with Consent of Noteholders. 

     With the consent (evidenced as provided in Article 13) of the holders of a majority in
aggregate principal amount of the Notes at the time outstanding, the Company, when authorized by
the resolutions of the Board of Directors, and the Trustee may, from time to time and at any time,
enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this Indenture or any

     (e) impair the right of any Noteholder to institute suit for the payment thereof;

     (f) make the principal thereof or Interest thereon payable in any coin or currency
other than that provided in the Notes;

     (g) impair the right to convert the Notes into Common Stock or reduce the number of

without the consent of the holder of each Note so affected;

     (p) reduce the aforesaid percentage of Notes, the holders of which are required to
consent to any such supplemental indenture,

     in each case, without the consent of the holders of all Notes affected thereby.

     Upon the written request of the Company, accompanied by a copy of the resolutions of the Board
of Directors certified by its Secretary or Assistant Secretary authorizing the execution of any
such supplemental indenture (in form satisfactory to the Trustee), and upon the filing with the
Trustee of evidence of the consent of the Noteholders as aforesaid, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such supplemental
indenture.

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

          Section 8.03.   Effect of Supplemental Indenture. 

     Upon the execution of any supplemental indenture pursuant to the provisions of this Article,
this Indenture shall be and shall be deemed to be modified and amended in accordance therewith and
the respective rights, limitation of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of the Notes shall thereafter be determined,
exercised and enforced hereunder, subject in all respects to such modifications and amendments and
all the terms and conditions of any such supplemental indenture shall be and shall be deemed to be
part of the terms and conditions of this Indenture for any and all purposes.

59

 

          Section 8.04.   Notation on Notes. 

     Notes authenticated and delivered after the execution of any supplemental indenture pursuant
to the provisions of this Article may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the Trustee shall so
determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such supplemental indenture may,
at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or
an authenticating agent duly appointed by the Trustee pursuant to Section 16.10) and
delivered in exchange for the Notes then outstanding, upon surrender of such Notes then
outstanding.

          Section 8.05.   Evidence of Compliance of Supplemental Indenture to Be Furnished to
Trustee. 

     Prior to entering into any supplemental indenture, or any amendment to any Security Document,
the Trustee shall be provided with, in addition to the documents required by Section 15.05,
an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental
indenture or amendment to any Security Document executed pursuant hereto complies with the
requirements of this Article and is otherwise authorized or permitted by this Indenture and, where
applicable, the Security Documents.

ARTICLE 9

GUARANTEES

          Section 9.01.   Guarantee.

     Subject to this Article 9, each Guarantor unconditionally guarantees to each holder of
a Note authenticated and delivered by the Trustee and to the Trustee and its successors and
assigns, the matters set out in the Guarantee executed by such Guarantor. Failing payment when due
of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors
shall be jointly and severally obligated to pay and perform the same immediately pursuant to the
terms of the Guarantee.

          Section 9.02.   Limitation on Guarantor Liability.

     (a) Each Guarantor, and by its acceptance of Notes, each holder, hereby confirms that it is
the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar foreign, federal or state law, or the laws of any
applicable jurisdiction, to the extent applicable to any guarantee. To effectuate the foregoing
intention, the Trustee, the holders and the Guarantors hereby irrevocably agree that each
Guarantor’s liability shall be that amount from time to time equal to the aggregate liability of
such Guarantor under the guarantee, but shall be limited to the lesser of (a) the aggregate amount
of the Company’s obligations under the Notes and this Indenture or (b) the amount, if any, which
would not have (1) rendered the Guarantor “insolvent” (as such term is defined in Bankruptcy Law
and in the Debtor and Creditor Law of the State of New York) or (2) left it with unreasonably small
capital at the time its guarantee with respect to the Notes was entered into, after giving effect
to the incurrence of existing Debt immediately before such time; provided, however, it shall be a
presumption in any lawsuit or proceeding in which a Guarantor is a party that the amount guaranteed

60

 

pursuant to the guarantee with respect to the Notes is the amount described in clause (a)
above unless any creditor, or representative of creditors of the Guarantor, or debtor in possession
or trustee in bankruptcy of the Guarantor, otherwise proves in a lawsuit that the aggregate
liability of the Guarantor is limited to the amount described in clause (b).

     (b) In making any determination as to the solvency or sufficiency of capital of a Guarantor in
accordance with the proviso of Section 9.02(a), the right of each Guarantor to contribution
from other Guarantors or any other Person and any other rights such Guarantor may have, contractual
or otherwise, shall be taken into account.

          Section 9.03.   Execution and Delivery of Guarantee

     To evidence its Guarantee, each Guarantor hereby agrees that a notation of such Guarantee in
substantially the form included in Exhibit B attached hereto shall be endorsed by an
Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this
Indenture shall be executed on behalf of such Guarantor by its President or one of its Vice
Presidents. Each Guarantor hereby agrees that its Guarantee shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Guarantee. If an Officer
whose signature is on this Indenture or on the Guarantee no longer holds that office at the time
the Trustee authenticates the Note on which a Guarantee is endorsed, the Guarantee shall be valid
nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder,
shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the
Guarantors.

ARTICLE 10

COLLATERAL AND SECURITY

          Section 10.01.   Security Documents.

     (a) The due and punctual payment of the principal of and interest on the Notes when and as the
same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration,
repurchase, redemption or otherwise, and interest on the overdue principal of and interest on the
Notes and any other amounts constituting the Repurchase Amount and performance of all other
obligations of the Company to the holders or the Trustee under this Indenture and the Notes,
according to the terms hereunder or thereunder, are secured as provided in the Security Documents,
including the Initial Security Documents which the Major Shareholder has entered into
simultaneously with the execution of this Indenture and which are attached as Exhibit E
hereto. Each holder, by its acceptance thereof, consents and agrees to the terms of the Security
Documents (including, without limitation, the provisions providing for foreclosure and release of
Collateral) as the same may be in effect or may be amended from time to time in accordance with its
terms and authorizes and directs the Collateral Agent to enter into the Security Documents and to
perform its obligations and exercise its rights thereunder as a secured party in accordance
therewith. The Company and the Chargor will do or cause to be done all such acts and things as may
be required by applicable law or may be necessary or proper, or as may be required by the
provisions of the Security Documents, to assure and confirm to the Collateral Agent and the Trustee
the security interest in the Collateral contemplated hereby, by the Security Documents or any part
thereof, as from time to time constituted, so as to render the same available for the security and
benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes
herein expressed. The Company and the Chargor will take, and will cause its Subsidiaries to take,
any and all actions reasonably required to cause the Security

61

 

Documents to create and maintain, as security for the Note Obligations, a valid and
enforceable Lien in and on all the Collateral as described in each Collateral Document, in favor of
the Collateral Agent, as secured party, for the benefit of the holders, superior to and prior to
the rights of all third Persons and subject to no other Liens other than as permitted under the
Security Documents.

          Section 10.02.   Release of Collateral.

     (a) At any time when a Default or an Event of Default has occurred and is continuing and the
maturity of the Notes has been accelerated (whether by declaration or otherwise), no release of
Collateral pursuant to the provisions of the Security Documents will be effective as against the
holders.

     (b) Upon any conversion of the Notes into Common Stock of the Company pursuant to Article
15, at the request of the Chargor, YGE Share Collateral subject to the YGE Share Charge shall
be released from the YGE Share Charge but only to the extent that, as of the applicable date that
the Common Stock is issued pursuant to such conversion, the quotient of (i) the number of shares of
Common Stock remaining subject to the YGE Share Charge (after giving effect to the proposed
release) multiplied by the Current Market Price determined as of the date of conversion,
divided by (ii) the outstanding principal balance of the Notes (after giving effect to the
conversion), immediately is equal to 1.13 (representing the deemed value of the 10,000,000 shares
of Common Stock initially subject to the YGE Share Charge at the initial Conversion Price of $5.65
per share (i.e., $56,500,000), divided by $50,000,000, which is the aggregate principal amount of
the Notes potentially issuable under this Indenture), provided that all of the YGE Share Collateral
shall be released from the YGE Share Charge if no Notes remain outstanding (after giving effect to
the conversion). Upon the receipt of written request from the Company and an accompanying
Officer’s Certificate certifying that the conditions set forth in this Section 10.02(b) have been
satisfied, the Trustee shall provide such instructions to the Collateral Agent as the Company may
reasonably request so as to effect the release of YGE Share Collateral pursuant to this Section
10.02; provided that the Noteholders will be given at least five (5) Business Days prior
written notice before any release of the YGE Share Collateral pursuant to this Section
10.02.

     (c) The release of any Collateral from the terms of this Indenture and the Security Documents
will not be deemed to impair the security under this Indenture in contravention of the provisions
hereof if and to the extent the Collateral is released pursuant to the terms of the Security
Documents and hereof.

          Section 10.03.   Authorization of Actions to Be Taken by the Trustee Under the Security
Documents.

     Subject to the provisions of Section 7.01 and 7.02, the Trustee may, in its
sole discretion and without the consent of the holders, take, on behalf of the holders, all actions
it deems necessary or appropriate in order to:

     (a) enforce any of the terms of the Security Documents; and

     (b) collect and receive any and all amounts payable in respect of the Note Obligations.

     The Trustee will have power to institute and maintain such suits and proceedings as it may
deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in
violation of the Security Documents or this Indenture, and such suits and proceedings as the
Trustee may deem expedient to preserve or protect its interests and the interests of the holders in
the Collateral (including power to institute

62

 

and maintain suits or proceedings to restrain the enforcement of or compliance with any
legislative or other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would
impair the security interest hereunder or be prejudicial to the interests of the holders or of the
Trustee).

          Section 10.04.   Authorization of Receipt of Funds by the Trustee Under the Security
Documents.

     The Trustee is authorized to receive any funds for the benefit of the holders distributed
under the Security Documents, and to make further distributions of such funds to the holders
according to the provisions of this Indenture.

          Section 10.05.   Termination of Security Interest.

     Upon the payment in full of all Obligations of the Company under this Indenture and the Notes,
the Trustee will, at the request of the Company, promptly instruct the Collateral Agent to release
the Liens pursuant to this Indenture and the Security Documents.

          Section 10.06.   Appointment of Collateral Agent. 

     The parties hereto acknowledge and agree, and each Noteholder by accepting a Note acknowledges
and agrees, that the Company hereby irrevocably appoints DB Trustees (Hong Kong) Limited as
Collateral Agent hereunder. The Collateral Agent shall have such duties and responsibilities, with
respect to the Noteholders, as are explicitly set forth herein and in the Security Document to
which it is a party and no others; provided that the Collateral Agent shall only take action with
respect to or under the Security Document in accordance with the written instructions of the
Trustee acting on behalf of the Noteholders, or Noteholders holding not less than 25% of the
principal amount of the Notes then outstanding, and shall apply any proceeds from the enforcement
of any security, as set forth in this Indenture. The Trustee may delegate any of its rights and
responsibilities with respect to the Collateral and all matters pertaining thereto hereunder or
under the Security Documents to the Collateral Agent. The provisions of this Article 10
relating to the Trustee acting in such capacity shall apply to the Collateral Agent to the extent
applicable. In addition, the Company hereby agrees to indemnify the Collateral Agent with respect
to the Collateral Agent’s duties under this Indenture and the Security Documents on the same basis,
to the same extent and subject to the same limitations, as the Company’s indemnification of the
Trustee pursuant to Section 7.06.

ARTICLE 11

SURETYSHIP WAIVERS

     Each Guarantor and the Chargor hereby agrees that its obligations with regard to its Guarantee
or Security Document, as the case may be, shall be joint and several, unconditional, irrespective
of the validity or enforceability of the Notes or the obligations of the Company, any Guarantor or
the Chargor under this Indenture or the other Transaction Documents, the absence of any action to
enforce the same, the recovery of any judgment against the Company or any other obligor with
respect to this Indenture, the Notes, the other Transaction Documents or the Obligations of the
Company, the Guarantors and the Chargor under this Indenture, the Notes and the other Transaction
Documents, any action to enforce the same or any other circumstances (other than complete
performance) which might otherwise constitute a legal or equitable discharge or defense of a
Guarantor or Chargor. Each Guarantor and Chargor further, to the extent permitted by law, waives
and relinquishes all claims, rights and remedies accorded by applicable law to

63

 

guarantors and sureties and agrees not to assert or take advantage of any such claims, rights
or remedies, including but not limited to: (a) any right to require any of the Trustee, the
holders, the Company, any other Guarantor or any other Chargor (each a “Benefited Party”),
as a condition of payment or performance by such Guarantor or Chargor (or as a condition to the
enforcement against any Collateral or any other right or remedy granted pursuant to the Security
Documents or under applicable law), to (1) proceed against the Company, any other guarantor
(including any other Guarantor) of the Obligations, any other Person providing security for the
Obligations (including the Chargor) or any other Person, (2) proceed against or exhaust any
security held from the Company, any other guarantor, any Person providing security for the
Obligations or any other Person, (3) proceed against or have resort to any balance of any deposit
account or credit on the books of any Benefited Party in favor of the Company or any other Person,
or (4) pursue any other remedy in the power of any Benefited Party whatsoever; (b) any defense
arising by reason of the incapacity, lack of authority or any disability or other defense of the
Company including any defense based on or arising out of the lack of validity or the
unenforceability of the Obligations under the Guarantees or any of the obligations or the security
under the Security Documents or any defense or any agreement or instrument relating thereto or by
reason of the cessation of the liability of the Company from any cause other than payment in full
of the Obligations under the Notes and the Guarantees; (c) any defense based upon any statute or
rule of law which provides that the obligation of a surety must be neither larger in amount nor in
other respects more burdensome than that of the principal; (d) any defense based upon any Benefited
Party’s errors or omissions in the administration of the Obligations under the Notes or the
Guarantees or the security or rights or remedies provided under the Security Dcouments, except
behavior which amounts to bad faith; (e)(1) any principles or provisions of law, statutory or
otherwise, which are or might be in conflict with the terms of the Guarantees or Security Documents
and any legal or equitable discharge of such Guarantor’s or Chargor’s obligations hereunder or
thereunder, (2) the benefit of any statute of limitations affecting such Guarantor’s or Chargor’s
liability hereunder or the enforcement hereof, (3) any rights to set-offs, recoupments and
counterclaims and (4) promptness, diligence and any requirement that any Benefited Party protect,
secure, perfect or insure any security interest or lien or any property subject thereto; (f)
notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of
any action or inaction, including acceptance of the Guarantees, acceptance of the Security
Documents, notices of Default under the Notes or any agreement or instrument related thereto,
notices of any renewal, extension or modification of the Obligations under the Notes or the
Guarantees or any agreement related thereto, and notices of any extension of credit to the Company
and any right to consent to any thereof; (g) to the extent permitted under applicable law, the
benefits of any “One Action” or similar rule of any jurisdiction and (h) any defenses or benefits
that may be derived from or afforded by law which limit the liability of or exonerate guarantors or
sureties or parties providing security for the obligations of another, or which may conflict with
the terms of the Guarantees or the Security Documents. Except to the extent expressly provided
herein, including Section 9.05, each Guarantor hereby covenants that its Guarantee and the
Chargor covenants that the obligations and security provided under the applicable Security Document
shall not be discharged except by complete performance of the obligations contained herein, in the
Notes, in the applicable Guarantee and in the applicable Security Document.

     If any holder or the Trustee is required by any court or otherwise to return to the Company,
the Guarantors, any Chargor or any custodian, trustee, liquidator or other similar official acting
in relation to either the Company, the Guarantors or the Chargor, any amount paid by either to the
Trustee, such holder or Collateral Agent, the Guarantee of such Guarantor and the Security Document
(and all of the security interests and all other rights and remedies granted therein), to the
extent theretofore discharged, shall be reinstated in full force and effect.

64

 

     Each Guarantor and the Chargor agrees that it shall not be entitled to any right of
subrogation in relation to the holders in respect of any obligations guaranteed or secured until
payment in full of all obligations guaranteed or secured, as the case may be. Each Guarantor and
the Chargor further agrees that, as between the Guarantors and the Chargor, on the one hand, and
the holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed and
secured under the applicable Transaction Documents may be accelerated as provided in Section
6.01 for the purposes of the Guarantee and the applicable Security Documents and the rights and
remedies granted therein, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations so guaranteed or secured and (y) in the event of any
declaration of acceleration of such obligations as provided in Section 6.01, such
obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of the Guarantee and the Trustee and the holders shall have all rights
and remedies available to them in accordance the Security Documents and applicable law. The
Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the holders under the Guarantee.

ARTICLE 12

SATISFACTION AND DISCHARGE OF INDENTURE

          Section 12.01.   Discharge of Indenture. 

     When (a) the Company shall deliver to the Trustee for cancellation all Notes theretofore
authenticated (other than any Notes that have been mutilated, destroyed, lost or stolen and in lieu
of or in substitution for which other Notes shall have been authenticated and delivered) and not
theretofore cancelled, or (b) all the Notes not theretofore cancelled or delivered to the Trustee
for cancellation shall have become due and payable at their scheduled maturity or upon repurchase
or redemption in accordance with the terms of this Indenture, and the Company shall deposit with
the Trustee, in trust, funds sufficient to pay at maturity or upon such repurchase or redemption of
all of the Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen
and in lieu of or in substitution for which other Notes shall have been authenticated and
delivered) not theretofore cancelled or delivered to the Trustee for cancellation, all amounts due
and owing on such Notes, including any Repurchase Amount, all principal and all Interest due or to
become due to such date of maturity or repurchase or redemption date, as the case may be,
accompanied by a verification report, as to the sufficiency of the deposited amount, from an
independent certified accountant or other financial professional satisfactory to the Trustee, and
if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company,
and in the case of either clause (a) or (b), no Default or Event of Default with respect to this
Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall
occur as a result of such deposit and such deposit shall not result in a breach or violation of, or
constitute a default under, any other instrument or agreement to which the Company is a party or by
which it is bound, then this Indenture shall cease to be of further effect (except as to (i)
remaining rights of registration of transfer, substitution and exchange and conversion of Notes,
(ii) Articles 3, 7, 9, 10, 11, 12 and 15,
and (iii) rights hereunder of Noteholders to receive payments of principal of and Interest and any
other amounts due and owing on the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the
Trustee, and (iv) the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on written demand of the Company accompanied by an Officers’ Certificate as required by
Section 16.05 and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees
to reimburse the Trustee for any costs or expenses thereafter incurred by the Trustee and to
compensate the

65

 

Trustee for any services thereafter rendered by the Trustee in connection with this Indenture
or the Notes. The Trustee shall hold in trust money deposited with it pursuant to this Article. It
shall apply the deposited money through the Paying Agent and in accordance with this Indenture to
the payment of principal of and Interest on the Notes.

          Section 12.02.   Deposited Monies to Be Held in Trust by Trustee. 

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

          Section 12.03.   Paying Agent to Repay Monies Held. 

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

          Section 12.04.   Return of Unclaimed Monies. 

     Subject to the requirements of applicable law, any monies deposited with or paid to the
Trustee for payment of the principal or Interest on Notes and not applied but remaining unclaimed
by the holders of Notes for two (2) years (or such shorter period of time under applicable escheat
law) after the date upon which the principal of or Interest on such Notes, as the case may be,
shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all
liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any
of the Notes shall thereafter look only to the Company for any payment that such holder may be
entitled to collect unless an applicable abandoned property law designates another Person.

          Section 12.05.   Reinstatement. 

     If the Trustee or the paying agent is unable to apply any money in accordance with Section
12.02 by reason of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company’s obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 12.01 until such time as the Trustee or the paying agent is permitted to apply
all such money in accordance with Section 12.02; provided that, if the Company makes any
payment of Interest on or principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to receive such payment from
the money held by the Trustee or paying agent.

ARTICLE 13

THE NOTEHOLDERS

          Section 13.01.   Action by Noteholders. 

66

 

     Whenever in this Indenture it is provided that the holders of a specified percentage in
aggregate principal amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other action), the fact
that, at the time of taking any such action, the holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of similar tenor
executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record
of the holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held
in accordance with the provisions of Article 14, or (c) by a combination of such instrument
or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the
Trustee solicits the taking of any action by the Noteholders, the Company or the Trustee may fix in
advance of such solicitation a date as the record date for determining holders entitled to take
such action. The record date for purpose of determining the identity of Noteholders entitled to
vote or consent to any action shall be not more than fifteen (15) days prior to the date of
commencement of solicitation of such action.

          Section 13.02.   Proof of Execution by Noteholders. 

     Subject to the provisions of Sections 7.01, 7.02 and 14.04, proof of
the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made
in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the
registry of such Notes or by a certificate of the Registrar.

     The record of any Noteholders’ meeting shall be proved in the manner provided in Section
14.05.

          Section 13.03.   Who Are Deemed Absolute Owners. 

     The Company, the Trustee, any paying agent, any conversion agent, any Collateral Agent and any
Registrar may deem the Person in whose name such Note shall be registered upon the Security
Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any
Person other than the Company or any Registrar) for the purpose of receiving payment of or on
account of the principal of and Interest on such Note, for conversion of such Note and for all
other purposes; and neither the Company nor the Trustee nor any paying agent, Collateral Agent,
conversion agent nor any Registrar shall be affected by any notice to the contrary. All such
payments so made to any holder for the time being, or upon such holder’s order, shall be valid and,
to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for
monies payable upon any such Note.

          Section 13.04.   Company-owned Notes Disregarded. 

     In determining whether the holders of the requisite aggregate principal amount of the Notes
have concurred in any direction, consent, waiver, notice, determination or other action under this
Indenture (including pursuant to Article 6), Notes which are owned by the Company, any Guarantor,
any Chargor or any other obligor on the Notes or any Affiliate of the Company, any Guarantor, any
Chargor or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for
the purpose of any such determination; provided that, for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, consent, waiver or other action, only
Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which
have been pledged in good faith may be regarded as outstanding for the purposes of this Section if
the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such
Notes and that the pledgee is not the Company, any Guarantor,

67

 

any Chargor or any other obligor on the Notes or any Affiliate of the Company, any Guarantor,
any Chargor or any such other obligor. In the case of a dispute as to such right, any decision by
the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request
of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing
and identifying all Notes, if any, known by the Company to be owned or held by or for the account
of any of the above-described Persons, and, subject to Section 7.01, the Trustee shall be
entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth
and of the fact that all Notes not listed therein are outstanding for the purpose of any such
determination.

          Section 13.05.   Revocation of Consents; Future Holders Bound. 

     At any time prior to (but not after) the evidencing to the Trustee, as provided in Section
13.01, of the taking of any action by the holders of the percentage in aggregate principal
amount of the Notes specified in this Indenture in connection with such action, any holder of a
Note which is shown by the evidence to be included in the Notes the holders of which have consented
to such action may, by filing written notice with the Trustee at its Corporate Trust Office and
upon proof of holding as provided in Section 12.02, revoke such action so far as concerns
such Note. Except as aforesaid, any such action taken by the holder of any Note shall be
conclusive and binding upon such holder and upon all future holders and owners of such Note and of
any Notes issued in exchange or substitution therefor, irrespective of whether any notation in
regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

ARTICLE 14

MEETINGS OF NOTEHOLDERS

          Section 14.01.   Purpose of Meetings. 

     A meeting of Noteholders may be called at any time and from time to time pursuant to the
provisions of this Article for any of the following purposes:

     (a) to give any notice to the Company or to the Trustee or to give any directions to
the Trustee permitted under this Indenture, or to consent to the waiving of any Default or
Event of Default hereunder and its consequences, or to take any other action authorized to
be taken by Noteholders pursuant to any of the provisions of Article 6;

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

     (c) to consent to the execution of an indenture or indentures supplemental hereto
pursuant to the provisions of Section 8.02; or

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

          Section 14.02.   Call of Meetings by Company or Noteholders. 

68

 

     In case at any time the Company, pursuant to a resolution of its Board of Directors, or the
holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes then
outstanding, shall have requested the Trustee to call a meeting of Noteholders, by written request
setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee
shall not have mailed the notice of such meeting within twenty (20) days after receipt of such
request, then the Company or such Noteholders may determine the time and the place for such meeting
and may call such meeting to take any action authorized in Section 12.01 by mailing a
notice of meeting. Notice of every meeting of the Noteholders, setting forth the time and place of
such meeting and in general terms the action proposed to be taken at such meeting and the
establishment of any record date pursuant to Section 13.01, shall be mailed to holders of
Notes at their addresses as they shall appear on the Security Register. Such notice shall also be
mailed to the Company. Such notices shall be mailed not less than twenty (20) nor more than ninety
(90) days prior to the date fixed for the meeting.

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

          Section 14.03.   Qualifications for Voting. 

     To be entitled to vote at any meeting of Noteholders, a person shall (a) be a holder of one or
more Notes on the record date pertaining to such meeting or (b) be a person appointed by an
instrument in writing as proxy by a holder of one or more Notes on the record date pertaining to
such meeting. The only persons who shall be entitled to be present or to speak at any meeting of
Noteholders shall be the persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the Company and its
counsel.

          Section 14.04.   Regulations. 

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

     The Company or the Noteholders calling the meeting, as the case may be, shall, by an
instrument in writing, appoint a temporary chairman of the meeting. A permanent chairman and a
permanent secretary of the meeting shall be elected by vote of the holders of a majority in
principal amount of the Notes represented at the meeting and entitled to vote at the meeting.

     Subject to the provisions of Section 13.04, at any meeting each Noteholder or
proxyholder shall be entitled to one vote for each $100,000 principal amount of Notes held or
represented by him; provided that no vote shall be cast or counted at any meeting in respect of any
Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding.
The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him
or instruments in writing as aforesaid duly designating him as the proxy to vote on behalf of other
Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section
14.02 may be adjourned from time to time by the holders of a majority of the aggregate
principal amount of the Notes represented at the meeting, whether or not constituting a majority

69

 

of the aggregate principal amount of the Notes outstanding, the latter of which shall
constitute a quorum, and the meeting may be held as so adjourned without further notice.

          Section 14.05.   Voting. 

     The vote upon any resolution submitted to any meeting of the Noteholders shall be by written
ballot on which shall be subscribed the signatures of the holders of Notes or of their
representatives by proxy and the outstanding principal amount of the Notes held or represented by
them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all votes cast at the
meeting. A record in duplicate of the proceedings of each meeting of the Noteholders shall be
prepared by the secretary of the meeting, and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was mailed as provided in Section 14.02. The record shall show
the principal amount of the Notes voting in favor of or against any resolution. The record shall
be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and
one of the duplicates shall be delivered to the Company and the other to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

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

          Section 14.06.  No Delay of Rights by Meeting.

     Nothing contained in this Article shall be deemed or construed to authorize or permit, by
reason of any call of a meeting of the Noteholders or any rights expressly or impliedly conferred
hereunder to make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Noteholders under any of the provisions of this
Indenture or of the Notes.

ARTICLE 15

CONVERSION OF NOTES

          Section 15.01.   Right to Convert. 

     (a) Subject to and upon compliance with the provisions of this Indenture, the holder of any
Note shall have the right, at such holder’s option at any time prior to the close of business on
the date of maturity of the Notes, to convert the principal amount of the Note, or any portion of
such principal amount which is in a minimum amount of $100,000 and a multiple of $1,000 in excess
thereof (or if less, the outstanding principal amount of such Note), into fully paid and
non-assessable shares of Common Stock (as such shares shall then be constituted) at the Conversion
Rate in effect at such time, by surrender of the Note so to be converted in whole or in part,
together with any required funds, under the circumstances described in this Section and in the
manner provided in Section 15.02.

     (b) A Note in respect of which a holder is electing to exercise its option to require the
Company to purchase such holder’s Notes upon a Change of Control Offer or Termination of Trading
Offer pursuant to Section 3.02 may be converted only if such holder withdraws its election
in accordance with Section 3.02. A holder of Notes is not entitled to any rights of a
holder of Common Stock until such holder has converted

70

 

his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted
to Common Stock under this Article.

          Section 15.02.   Exercise of Conversion Right; Issuance of Common Stock on Conversion; No
Adjustment for Interest or Dividends. 

     In order to exercise the conversion right with respect to any Note, a Noteholder must deliver
to the Conversion Agent (or the Trustee if no Conversion Agent has been appointed), such Note with
the original or facsimile of the form entitled “Conversion Notice” on the reverse thereof,
duly completed and manually signed, together with such Notes duly endorsed for transfer,
accompanied by the funds, if any, required by this Section. Such notice shall also state the name
or names (with address or addresses) in which the certificate or certificates for shares of Common
Stock which shall be issuable on such conversion shall be issued, and shall be accompanied by
transfer or similar taxes, if required pursuant to Section 15.07. Upon receipt of such
Conversion Notice and the Notes, the Conversion Agent (or the Trustee, as applicable) shall
promptly notify the Company and forward the same to the Company.

     As promptly as practicable after satisfaction of the requirements for conversion set forth
above, subject to compliance with any restrictions on transfer if shares issuable on conversion are
to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of
the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver to
such Noteholder at the office or agency maintained by the Company for such purpose pursuant to
Section 4.02 a certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such Note or portion thereof as determined by the Company in
accordance with the provisions of this Article and a check or cash in respect of any fractional
interest in respect of a share of Common Stock arising upon such conversion, calculated by the
Company as provided in Section 15.03. In case any Note of a denomination greater than
$100,000 shall be surrendered for partial conversion, and subject to Section 2.03, the
Company shall execute and the Trustee shall upon receipt of an Authentication Order authenticate
and deliver to the holder of the Note so surrendered, without charge to such holder, a new Note or
Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Note.

     Each conversion shall be deemed to have been effected as to any such Note (or portion thereof)
on the date (the “Conversion Date”) on which the requirements set forth above in this
Section have been satisfied as to such Note (or portion thereof), and the Person whose name is
entered in the Company’s register of members for Common Stock upon such conversion shall be deemed
to have become on said date the holder of record of the shares set out against his name in such
register; provided that any surrender on any date when the stock transfer books of the Company
shall be closed shall constitute such Person the record holder for all purposes at such time as his
name is entered on the register after the books are open again, but such conversion shall be at the
Conversion Rate in effect on the date upon which such Note shall be surrendered.

     Any Note or portion thereof surrendered for conversion during the period from the close of
business on the record date for any Interest Payment Date to the close of business on the Business
Day preceding such Interest Payment Date shall be accompanied by payment, in immediately available
funds or other funds acceptable to the Company, of an amount equal to the Interest otherwise
payable on such Interest Payment Date on the principal amount being converted; provided that no
such payment need be made (1) if the Company has specified a Purchase Date that is after a record
date and on or prior to the next Interest Payment Date or (2) to the extent of any overdue
Interest, if any overdue Interest exists at the time of conversion with respect to such Note.
Except as provided above in this Section, no payment or other

71

 

adjustment shall be made for Interest accrued on any Note converted or for dividends on any
shares issued upon the conversion of such Note as provided in this Article.

     The Company shall notify the Trustee in writing of any conversions of Notes effected through
any conversion agent other than the Trustee.

     Upon the conversion of a Note, that portion of the accrued but unpaid Interest, to the
Conversion Date, with respect to the converted Note shall not be cancelled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the holder thereof through delivery of
the Common Stock (together with the cash payment, if any in lieu of fractional shares) in exchange
for the Note being converted pursuant to the provisions hereof.

          Section 15.03.   Cash Payments in Lieu of Fractional Shares. 

     No fractional shares of Common Stock or scrip certificates representing fractional shares
shall be issued upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares that shall be issuable upon
conversion shall be computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share
of stock would be issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment and payment therefor in cash at the Current Market Price on the last Trading Day
immediately preceding the Conversion Date thereof to the holder of Notes.

          Section 15.04.   Conversion Rate. 

     Each $100,000 principal amount of the Notes shall be initially convertible into 17,699 shares
of Common Stock (herein called the “Conversion Rate”), as specified in the form of Note
attached as Exhibit A hereto, subject to adjustment as provided in this Article. Each of
the Second Tranche Notes shall initially be convertible at the Conversion Rate applicable to the
other outstanding Notes at the time such Second Tranche Notes are issued.

          Section 15.05.   Adjustment of Conversion Rate. 

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

     (a) In case the Company shall hereafter pay a dividend or make a distribution to all
holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall
be increased so that the same shall equal the rate determined by multiplying the Conversion
Rate in effect at the opening of business on the date following the Record Date (as defined
in Section 15.05(j)(ii)) for such dividend or other distribution by a fraction,

     (i) the numerator of which shall be the sum of the number of shares of Common
Stock outstanding at the close of business on the Record Date for such dividend or
other distribution plus the total number of shares of Common Stock constituting such
dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the Record Date,

72

 

such increase to become effective immediately after the opening of business on the day
following the Record Date. For the purpose 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. The Company will not pay any dividend or make any distribution on shares of
Common Stock held in the treasury of the Company. If any dividend or distribution of the
type described in this Section 15.05(a) is declared but not so paid or made, the
Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect
if such dividend or distribution had not been declared.

     (b) In case the Company shall issue rights or warrants to all holders of its
outstanding shares of Common Stock entitling them (for a period expiring within forty-five
(45) days after the Record Date for such rights or warrants) to subscribe for or purchase
shares of Common Stock at a price per share less than the Current Market Price immediately
preceding the date such distribution is first publicly announced by the Company, the
Conversion Rate shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the Record Date for such
rights or warrants by a fraction,

     (i) the numerator of which shall be the number of shares of Common Stock
outstanding on the Record Date for such rights or warrants plus the total number of
additional shares of Common Stock offered for subscription or purchase, and

     (ii) the denominator of which shall be the sum of the number of shares of
Common Stock outstanding at the close of business on the Record Date for such rights
or warrants plus the number of shares that the aggregate offering price of the total
number of shares so offered would purchase at a price equal to the Current Market
Price immediately preceding the date such distribution is first publicly announced
by the Company,

such adjustment shall be successively made whenever any such rights or warrants are issued,
and shall become effective immediately after the opening of business on the day following
the Record Date for such rights or warrants. To the extent that shares of Common Stock are
not delivered after the expiration of such rights or warrants, the Conversion Rate shall be
readjusted to the Conversion Rate that would then be in effect had the adjustments made upon
the issuance of such rights or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights or warrants are not so
issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such date fixed for the determination of shareholders entitled to
receive such rights or warrants had not been fixed. In determining whether any rights or
warrants entitle the holders to subscribe for or purchase shares of Common Stock at a price
less than the Current Market Price immediately preceding the date such distribution is first
publicly announced by the Company, and in determining the aggregate offering price of such
shares of Common Stock, there shall be taken into account any consideration received by the
Company for such rights or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined by the Board
of Directors.

     (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
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
Common Stock shares of any class of capital stock of the Company or evidences of its
indebtedness or assets (including securities, but excluding any rights or warrants referred
to in Section 15.05(b), and excluding any dividend or distribution (x) paid
exclusively in cash or (y) referred to in Section 15.05(a)) (any of the foregoing
hereinafter in this Section 15.05(d) called the “Securities”)), then, in
each such case (unless the Company elects to reserve such Securities for distribution to the
Noteholders upon the conversion of the Notes so that any such holder converting Notes will
receive upon such conversion, in addition to the shares of Common Stock to which such holder
is entitled, the amount and kind of such Securities which such holder would have received if
such holder had converted its Notes into Common Stock immediately prior to the Record Date
for such distribution of the Securities) the Conversion Rate shall be increased so that the
same shall be equal to the rate determined by multiplying the Conversion Rate in effect on
the Record Date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the Current Market Price on such Record
Date; and

     (ii) the denominator of which shall be the Current Market Price on such Record
Date less the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive, and described in a resolution of the Board of
Directors) on the Record Date of the portion of the Securities so distributed
applicable to one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business on the day
following such Record Date; provided that, if the then fair market value (as so determined)
of the portion of the Securities so distributed applicable to one share of Common Stock is
equal to or greater than the Current Market Price on the Record Date, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Noteholder shall have
the right to receive upon conversion the amount of Securities such holder would have
received had such holder converted each Note on the Record Date. If such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. If the Board of Directors determines the fair market value of any distribution
for purposes of this Section 15.05(d) by reference to the actual or when issued
trading market for any securities, it must in doing so consider the prices in such market
over the same period used in computing the Current Market Price on the applicable Record
Date. Notwithstanding the foregoing, if the Securities distributed by the Company to all
holders of its Common Stock consist of capital stock of, or similar equity interests in, a
Subsidiary or other business unit, the Conversion Rate shall be increased so that the same
shall be equal to the rate determined by multiplying the Conversion Rate in effect on the
Record Date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the sum of (A) the Current Market Price on
and including the fifth Trading Day after the Ex-Dividend Time plus (B) the fair
market

74

 

value of the securities distributed in respect of each share of Common Stock
for which this Section 15.05(d) applies, which shall equal the number of
Securities distributed in respect of each share of Common Stock multiplied by the
average of the closing sale prices of those Securities distributed (where such
closing sale prices are available) for the ten (10) Trading Days commencing on and
including the tenth Trading Day after the Ex-Dividend Time; and

     (ii) the denominator of which shall be the average of the Current Market Price
on and including the fifth Trading Day after the Ex-Dividend Time,

such adjustment to become effective immediately prior to the opening of business on the day
following such Record Date; provided that the Company may in lieu of the foregoing
adjustment make adequate provision so that each Noteholder shall have the right to receive
upon conversion the amount of Securities such holder would have received had such holder
converted each Note on the Record Date with respect to such distribution.

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

     No adjustment of the Conversion Rate shall be made pursuant to this Section
15.05(d) in respect of rights or warrants distributed or deemed distributed on any
Trigger Event to the extent

75

 

that such rights or warrants are actually distributed, or reserved by the Company for
distribution to holders of Notes upon conversion by such holders of Notes to Common Stock.

     For purposes of this Section 15.05(d) and Sections 15.05(a) and
15.05(b), any dividend or distribution to which this Section 15.05(d) is
applicable that also includes shares of Common Stock, or rights or warrants to subscribe for
or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend
or distribution of the evidences of indebtedness, assets or shares of capital stock other
than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment
required by this Section 15.05(d) with respect to such dividend or distribution
shall then be made) immediately followed by (2) a dividend or distribution of such shares of
Common Stock or such rights or warrants (and any further Conversion Rate adjustment required
by Sections 15.05(a) and 15.05(b) with respect to such dividend or
distribution shall then be made), except (A) the Record Date of such dividend or
distribution shall be substituted as “the date fixed for the determination of shareholders
entitled to receive such dividend or other distribution”, “the date fixed for the
determination of shareholders entitled to receive such rights or warrants” and “the date
fixed for such determination” within the meaning of Sections 15.05(a) and
15.05(b) and (B) any shares of Common Stock included in such dividend or
distribution shall not be deemed “outstanding at the close of business on the date fixed for
such determination” within the meaning of Section 15.05(a).

     (e) In case the Company shall, by dividend or otherwise, distribute to all holders of
its Common Stock cash (excluding any dividend or distribution in connection with the
liquidation, dissolution or winding up of the Company, whether voluntary or involuntary),
then, in such case, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect immediately prior to the close
of business on such Record Date by a fraction,

     (i) the numerator of which shall be the Current Market Price on such Record
Date; and

     (ii) the denominator of which shall be the Current Market Price on such Record
Date less the amount of cash so distributed applicable to one share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on the day
following the Record Date; provided that if the portion of the cash so distributed
applicable to one share of Common Stock is equal to or greater than the Current Market Price
on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Noteholder shall have the right to receive upon conversion the amount of cash such
holder would have received had such holder converted each Note on the Record Date. If such
dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such dividend or distribution had
not been declared.

     (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or
any portion of the Common Stock shall expire and such tender or exchange offer (as amended
upon the expiration thereof) shall require the payment to shareholders of consideration per
share of Common Stock having a fair market value (as determined by the Board of Directors,
whose determination shall be conclusive and described in a resolution of the Board of

76

 

Directors) that as of the last time (the “Expiration Time”) tenders or
exchanges may be made pursuant to such tender or exchange offer (as it may be amended)
exceeds the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding
the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect immediately prior to the
Expiration Time by a fraction,

     (i) the numerator of which shall be the sum of (x) the fair market value
(determined as aforesaid) of the aggregate consideration payable to shareholders
based on the acceptance (up to any maximum specified in the terms of the tender or
exchange offer) of all shares validly tendered or exchanged and not withdrawn as of
the Expiration Time (the shares deemed so accepted up to any such maximum, being
referred to as the “Purchased Shares”) and (y) the product of the number of
shares of Common Stock outstanding (less any Purchased Shares) at the Expiration
Time and the Closing Sale Price of a share of Common Stock on the Trading Day next
succeeding the Expiration Time, and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding (including any tendered or exchanged shares) at the Expiration Time
multiplied by the Closing Sale Price of a share of Common Stock on the Trading Day
next succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day
following the Expiration Time. If the Company is obligated to purchase shares pursuant to
any such tender or exchange offer, but the Company is permanently prevented by applicable
law from effecting any such purchases or all such purchases are rescinded, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such
tender or exchange offer had not been made.

     (g) On each March 31, June 30, September 30 and December 31 of each year, commencing on
June 30, 2010, the Conversion Rate shall be adjusted to equal the quotient obtained by
dividing (i) $100,000 by (ii) the Trading Reference VWAP (20 Day Backward Looking); provided
that no such adjustment shall be made if the number of shares issuable upon conversion of
the Notes at such adjusted Conversion Rate would be lower than the number of shares issuable
at then existing Conversion Rate (after giving effect to prior adjustments permitted
pursuant to this clause).

     (h) If at any time after the First Tranche Issue Date the Company shall issue or sell
its Common Stock or any securities exercisable or convertible into shares of Common Stock,
at a price per share or exercise or conversion price less than the Current Market Price then
in effect (and in the case of subclauses (ii) or (iii) below, issue or sell Common Stock or
any other securities exercisable or convertible into shares of Common Stock, whose purchase
price or exercise or conversion price is less than the Current Market Price then in effect),
the Conversion Rate shall be increased such that the Conversion Price is equal to the lowest
purchase price or exercise or conversion price at which the Company has issued or sold its
Common Stock or any securities exercisable or convertible into shares of Common Stock after
the First Tranche Issue Date such adjustment to take effect as of the date of the issuance
or sale of such Common Stock or securities; provided, however, that no adjustment shall be
made to the Conversion Price for (i) the issuance of Common Stock pursuant to the conversion
or exercise of convertible or exercisable securities issued or outstanding on or prior to
the First Tranche Issue Date or the Notes, (ii) the issuance of

77

 

Common Stock or any other securities exercisable or convertible into shares of Common
Stock pursuant to exercise of stock options granted or reserved under the Company’s employee
stock options existing on the First Tranche Issue Date or adopted thereafter in the ordinary
course of business, or (iii) the issuance, after the First Tranche Issue Date, of Common
Stock or any other securities exercisable or convertible into shares of Common Stock issued
or granted to third-party consultants or employees of the Company and its Subsidiaries under
the Company’s employee stock options plan or pursuant to written contractual arrangements
relating to the compensation for the services rendered to the Company or its Subsidiaries by
such consultants or employees, to the extent that all such shares or securities issued under
subclauses (ii) or (iii) in this paragraph, in the aggregate, on a cumulative basis and
without double counting, do not exceed five percent (5%) of the Common Stock of the Company
issued and outstanding immediately prior to such issuance.

     (i) The Conversion Rate shall be adjusted to the quotient obtained by dividing (i)
$100,000, by (ii) the Trading Reference VWAP (20 Day Forward Looking) as of each of the
following dates: (a) the date the Company releases its earnings results for fiscal year
2008, (b) the date the Company releases its earnings results for the second Fiscal Quarter
2009, and (c) the date the Company releases its earnings results for fiscal year 2009;
provided, that in the event the Company releases or otherwise makes public any preliminary
earnings estimates or any other material financial information with respect to the relevant
periods (whether by filing Form 6-K or otherwise), and the Trading Reference VWAP (20 Day
Forward Looking) as of the date of such release or publication is lower than the otherwise
applicable Trading Reference VWAP (20 Day Forward Looking), the Conversion Rate shall be
adjusted to the quotient obtained by dividing (A) $100,000, by (B) Trading Reference VWAP
(20 Day Forward Looking) as of the date of such release or publication; provided further,
that no such adjustment shall be made if the number of shares issuable upon conversion of
the Notes at such adjusted Conversion Rate would be lower than the number of shares issuable
at then existing Conversion Rate (after giving effect to prior adjustments permitted
pursuant to this clause).

     (j) For purposes of this Section 15.05, the following terms shall have the
meaning indicated:

     (i) “Current Market Price” shall mean the average of the daily Closing
Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days
ending on the earlier of the Trading Day immediately preceding the relevant date and
the day before the “ex” date with respect to the closing of the issuance,
distribution, subdivision or combination requiring such computation. For purpose of
this paragraph, the term “ex” date, (1) when used with respect to any issuance or
distribution, means the first date on which the Common Stock trades, regular way, on
the relevant exchange or in the relevant market from which the Closing Sale Price
was obtained without the right to receive such issuance or distribution, and (2)
when used with respect to any subdivision or combination of shares of Common Stock,
means the first date on which the Common Stock trades, regular way, on such exchange
or in such market after the time at which such subdivision or combination becomes
effective.

     If another issuance, distribution, subdivision or combination to which
Section 15.05 applies occurs during the period applicable for calculating
“Current Market Price” pursuant to the definition in the preceding paragraph,
“Current Market Price” shall be calculated for such period in a manner determined by
the Board of Directors to reflect the

78

 

impact of such issuance, distribution, subdivision or combination on the
Closing Sale Price of the Common Stock during such period.

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

     (k) The Company may make such increases in the Conversion Rate, in addition to those
required by Section 15.05(a) through (i) as the Board of Directors considers
to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to
purchase Common Stock resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes.

     To the extent permitted by applicable law, the New York Stock Exchange rules or any
other exchange on which the Common Stock of the Company is traded, 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) Business Days, the increase is irrevocable during the period and the
Board of Directors shall have made a determination that such increase would be in the best
interests of the Company, which determination shall be conclusive. Whenever the Conversion
Rate is increased pursuant to the preceding sentence, the Company shall mail to holders of
record of the Notes a notice of the increase 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.

     (l) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that any
adjustments that by reason of this Section 15.05(l) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. All
calculations under this Article shall be made by the Company and shall be made to the
nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.
Except as set forth in Section 15.05(h), no adjustment need be made for rights to
purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest
or for any issuance of Common Stock or convertible or exchangeable securities or rights to
purchase Common Stock or convertible or exchangeable securities. To the extent the Notes
become convertible into cash, assets, property or securities (other than capital stock of
the Company), no adjustment need be made thereafter as to the cash, assets, property or such
securities. Interest will not accrue on any cash into which the Notes are convertible.

     (m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall
promptly file with the Trustee and any conversion agent other than the Trustee an Officers’
Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible
Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not
be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the
last Conversion Rate

79

 

of which it has knowledge is still in effect. Promptly after delivery of such
certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate
setting forth the adjusted Conversion Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Rate to the holder
of each Note at his last address appearing on the Security Register provided for in
Section 4.02 of this Indenture, within twenty (20) days after execution thereof.
Failure to deliver such notice shall not affect the legality or validity of any such
adjustment.

     (n) In any case in which this Section provides that an adjustment shall become
effective immediately after (1) a record date or Record Date for an event, (2) the date
fixed for the determination of shareholders entitled to receive a dividend or distribution
pursuant to Section 15.05(a), (3) a date fixed for the determination of shareholders
entitled to receive rights or warrants pursuant to Section 15.05(b), or (4) the
Expiration Time for any tender or exchange offer pursuant to Section 15.05(f), (each
a “Determination Date”), the Company may elect to defer until the occurrence of the
applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note
converted after such Determination Date and before the occurrence of such Adjustment Event,
the additional shares of Common Stock or other securities issuable upon such conversion by
reason of the adjustment required by such Adjustment Event over and above the Common Stock
issuable upon such conversion before giving effect to such adjustment and (y) paying to such
holder any amount in cash in lieu of any fraction pursuant to Section 15.03. For
purposes of this Section 15.05(n), the term “Adjustment Event” shall mean:

     (i) in any case referred to in clause (1) hereof, the occurrence of such event,

     (ii) in any case referred to in clause (2) hereof, the date any such dividend
or distribution is paid or made,

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

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

     (o) For purposes of this Section, 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.

          Section 15.06.   Effect of Reclassification, Consolidation, Merger or Sale. 

     If any of the following events occur, namely (i) any reclassification or change of the
outstanding shares of Common Stock (other than (x) a subdivision or combination to which
Section 15.05(c) applies) as a result of which holders of Common Stock shall be entitled to
receive stock, other securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock, (ii) any consolidation, merger or combination of the Company with
another Person as a result of which holders of Common Stock shall be entitled to receive stock,
other securities or other property or assets (including

80

 

cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of
all or substantially all of the properties and assets of the Company to any other Person as a
result of which holders of Common Stock shall be entitled to receive stock, other securities or
other property or assets (including cash) with respect to or in exchange for such Common Stock,
then the Company or the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture (in form satisfactory to the Trustee) providing that each Note
shall be convertible into the kind and amount of shares of stock, other securities or other
property or assets (including cash) receivable upon such reclassification, change, consolidation,
merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable
upon conversion of such Notes (assuming, for such purposes, a sufficient number of authorized
shares of Common Stock are available to convert all such Notes) immediately prior to such
reclassification, change, consolidation, merger, combination, sale or conveyance assuming such
holder of Common Stock did not exercise such holder’s rights of election, if any, as to the kind
or amount of stock, other securities or other property or assets (including cash) receivable upon
such reclassification, change, consolidation, merger, combination, sale or conveyance (provided
that, if the kind or amount of stock, other securities or other property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger, combination, sale or
conveyance is not the same for each share of Common Stock in respect of which such rights of
election shall not have been exercised (“Non-electing share”), then for the purposes of
this Section the kind and amount of stock, other securities or other property or assets (including
cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or
conveyance for 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 which shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article.

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

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

     If this Section applies to any event or occurrence,
Section 15.05 shall not apply.

          Section 15.07.  Taxes on Shares Issued.

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

          Section 15.08.   Reservation of Shares; Shares to Be Fully Paid; Compliance with
Governmental Requirements; Listing of Common Stock. 

81

 

     The Company shall provide, free from preemptive rights, out of its authorized but unissued
shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion
of the Notes from time to time as such Notes are presented for conversion.

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

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

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

          Section 15.09.   Responsibility of the Conversion Agent. 

     The Conversion Agent shall not at any time be under any duty or responsibility to any
Noteholder to determine the Conversion Rate or whether any facts exist which may require any
adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any
such adjustment when made, or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. The Conversion Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any shares of Common
Stock, or of any securities or property, which may at any time be issued or delivered upon the
conversion of any Note; and the Conversion Agent makes no representations with respect thereto.
The Conversion Agent shall not be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or property or cash
upon the surrender of any Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article. Without limiting the
generality of the foregoing, the Conversion Agent shall not be under any responsibility to
determine the correctness of any provisions contained in any supplemental indenture entered into
pursuant to Section 15.06 relating either to the kind or amount of shares of stock or
securities or property (including cash) receivable by Noteholders upon the conversion of their
Notes after any event referred to in such Section 15.06 or to any adjustment to be made
with respect thereto, but, subject to the provisions of Section 7.01, may accept as
conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee
prior to the execution of any such supplemental indenture) with respect thereto.

          Section 15.10.   Notice to Holders Prior to Certain Actions. 

     In case:

82

 

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

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

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

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

the Company shall cause to be filed with the Trustee and to be sent to each Noteholder at such
holder’s address appearing on the Security Register provided for in Section 4.02 of this
Indenture, as promptly as possible but in any event at least ten (10) days prior to the applicable
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or
winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or
validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

          Section 15.11.   Shareholder Rights Plans. 

     Each share of Common Stock issued upon conversion of Notes pursuant to this Article shall be
entitled to receive the appropriate number of rights, if any, and the certificates representing the
Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be
provided by the terms of any shareholder rights plan adopted by the Company, as the same may be
amended from time to time. If at the time of conversion, however, the rights have separated from
the shares of Common Stock in accordance with the provisions of the applicable shareholder rights
agreement so that the holders of the Notes would not be entitled to receive any rights in respect
of Common Stock issuable upon conversion of the Notes, the conversion rate will be adjusted in
accordance with Section 15.05(d) treating all rights previously issued as Securities for
purposes of such adjustment, subject to readjustment in the event of the expiration, termination or
redemption of the rights.

          Section 16.04.   Governing Law, Consent to Jurisdiction and Service of Process. 

     THIS INDENTURE, THE GUARANTEE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAW OF THE STATE OF NEW YORK.

     The Company, the Guarantors and the Chargor irrevocably consent to the jurisdiction of the
courts of the State of New York and the courts of the United States of America located in the
Borough of Manhattan, City and State of New York over any suit, action or proceeding with respect
to this Indenture or the transactions contemplated hereby. The Company, the Guarantors and the
Chargor waive any objection that they may have to the venue of any suit, action or proceeding with
respect to this Indenture or the transactions contemplated hereby in the courts of the State of New
York or the courts of the United States of America, in each case, located in the Borough of
Manhattan, City and State of New York, or that such suit,

85

 

action or proceeding brought in the courts of the State of New York or the United States of
America, in each case, located in the Borough of Manhattan, City and State of New York was brought
in an inconvenient court and agrees not to plead or claim the same.

          To the extent that the Company, any Guarantor or any Operating Subsidiary has or hereafter may
acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from
jurisdiction of any court or from set-off or any legal process (whether service or notice,
attachment in aid or otherwise) with respect to itself or any of its property, the Company, each
Guarantor and the Chargor hereby irrevocably waives and agrees not to plead or claim such immunity
in respect of its obligations under this Indenture or the Notes.

     The Company, the Guarantors and the Chargor irrevocably appoint Law Debenture Corporate
Services Inc. acting through its office at 400 Madison Avenue, 4th Floor, New York, NY 10017,
U.S.A. (or its successors as agent for service of process) as its authorized agent (the
“Authorized Agent”) in the Borough of Manhattan in the city of New York upon which process
may be served in any law suit or proceeding, and agree that service of process upon such agent, and
written notice of said service to the Company, the Guarantors and the Chargor, as the case may be,
by the person serving the same to the address provided for the Company in Section 16.03,
shall be deemed in every respect effective service of process upon the Company, the Guarantors and
the Chargor, as the case may be, in any such suit or proceeding in any such action arising out of
or based on this Indenture. The Company, the Guarantors and the Chargor, as the case may be, shall
give notice to the Trustee of the appointment of a successor Authorized Agent. If for any reason
Law Debenture Corporate Services Inc. ceases to be able to act as the Authorized Agent of the
Company, the Guarantors or the Chargor, or ceases to have an address in the Borough of Manhattan,
the city of New York, the Company, the Chargor and the Guarantors will appoint a successor
Authorized Agent in accordance with the preceding sentence. Should the Company, any Guarantor or
any Chargor fail to appoint and/or maintain an agent for service of process, the Trustee shall be
entitled to appoint one for Company, the Chargor and the Guarantors (as the case may be), at the
Company’s or such Guarantor’s or Chargor’s cost.

          Section 16.05.   Evidence of Compliance with Conditions Precedent; Certificates to
Trustee. 

     Upon any application or demand by the Company to the Trustee to take any action under any of
the provisions of this Indenture, the Company shall furnish to the Trustee an Officers’ Certificate
stating that all conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with, all such conditions precedent have been complied with.

     Each certificate or opinion provided for in this Indenture and delivered to the Trustee with
respect to compliance with a condition or covenant provided for in this Indenture shall include:
(1) a statement that the person making such certificate or opinion has read such covenant or
condition; (2) a brief statement as to the nature and scope of the examination or investigation
upon which the statement or opinion contained in such certificate or opinion is based; (3) a
statement that, in the opinion of such person, he has made such examination or investigation as is
necessary to enable him to express an informed opinion as to whether or not such covenant or
condition has been complied with; and (4) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

          Section 16.06.   Legal Holidays. 

86

 

     In any case in which the date of maturity of Interest on or principal of the Notes or the
redemption date of any Note will not be a Business Day, then payment of such Interest on or
principal of the Notes need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the date of maturity or the redemption
date, and no Interest shall accrue for the period from and after such date.

          Section 16.07.   Company Responsible for Making Calculations.

     The Company will be responsible for making all calculations required under the Notes. The
Company will make these calculations in good faith and absent manifest error, these calculations
will be final and binding on the Noteholders. Promptly after the calculation thereof, the Company
will provide to each of the Trustee and any other conversion agent and Officers’ Certificate
setting forth a schedule of its calculations, and each of the Trustee and any other conversion
agent is entitled to conclusively rely upon the accuracy of such calculations without independent
verification. The Trustee will forward the Company’s calculations to any holder upon the written
request of such holder.

          Section 16.08.   Benefits of Indenture. 

     Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other
than the parties hereto, any paying agent, any authenticating agent, any conversion agent, any
Collateral Agent, any Registrar and their successors hereunder and the holders of Notes any benefit
or any legal or equitable right, remedy or claim under this Indenture.

          Section 16.09.   Table of Contents, Headings, Etc. 

     The table of contents and the titles and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be considered a part

          Section 16.10.   Authenticating Agent. 

     The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf,
and subject to its direction, in the authentication and delivery of Notes in connection with the
original issuance thereof and transfers and exchanges of Notes hereunder, including under
Sections 2.04, 2.05, 2.06, 2.07, 3.02, and 15.02,
as fully to all intents and purposes as though the authenticating agent had been expressly
authorized by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent
shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate
of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to
satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication.
Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder
pursuant to Section 7.07.

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

87

 

     Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Company.
Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee shall either
promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor
authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of a successor
authenticating agent to all holders of Notes as the names and addresses of such holders appear on
the Security Register.

     The Company agrees to pay to the authenticating agent from time to time such compensation for
its services as shall be agreed upon in writing between the Company and the authenticating agent.

     The provisions of Sections 7.02, 7.03, 7.04 and 13.03 and this
Section shall be applicable to any authenticating agent.

          Section 16.11.   Indenture and Notes Solely Corporate Obligations. 

     No recourse for the payment of the principal of, premium, if any, or Interest on any Note, or
for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture
or in any Note, or because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, shareholder, employee, agent, officer, director or subsidiary, as such,
past, present or future, of the Company or of any successor corporation, either directly or through
the Company or any successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood
that all such liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.

          Section 16.12.   Execution in Counterparts. 

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

          Section 16.13.   Severability. 

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

          Section 16.14.   Appointment of Co-Trustee. 

     (a) Notwithstanding any other provisions of this Indenture, following the occurrence
of, and during the continuation of, an Event of Default, hereunder, if the Trustee
reasonably believes that such action is either (i) required by law, rule or regulation of
the jurisdiction of incorporation of the Company or the jurisdiction in which the Company’s
principal place of business is located or (ii) is otherwise in the best interests of the
Noteholders, the Trustee shall have the power and may execute and deliver all instruments
necessary to appoint one or more Persons to

88

 

act as a co-trustee or co-trustees hereunder, or separate trustee or separate trustees
hereunder, in each case exclusively in such jurisdiction or jurisdictions, and to vest in
such Person or Persons, in such capacity and for the benefit of the holders, such title
hereunder, or any part hereof, in each case exclusively in such jurisdiction or
jurisdictions, and subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts in such jurisdiction or jurisdictions as the Trustee may
reasonably consider necessary or desirable. Each co-trustee and separate trustee hereunder
shall be authorized under applicable law to act as a co-trustee or a separate trustee, as
the case may be, and shall each have a combined capital and surplus (computed in accordance
with Section 3l0(a)(2) of the Trust Indenture Act) of at least $25,000,000. If at any time
a co-trustee or a separate trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with the effect
specified in this Section.

     (b) Every separate trustee and co-trustee shall, to the extent permitted by law, be
appointed and act subject to the following provisions and conditions:

     (i) all rights, powers, duties and obligations conferred or imposed upon the
Trustee shall be conferred or imposed upon and exercised or performed by the Trustee
and such separate trustee or co-trustee jointly (it being understood that such
separate trustee or co-trustee is not authorized to act (i) outside the jurisdiction
or jurisdictions set forth in Section 16.14(a) or (ii) separately without
the Trustee joining in such act), except to the extent that under any law of any
such jurisdiction in which any particular act or acts are to be performed the
Trustee shall be incompetent or unqualified to perform such act or acts, in which
event such rights, powers, duties and obligations shall be exercised and performed
singly by such separate trustee or co-trustee, but solely in such jurisdiction or
jurisdictions and solely at the direction of the Trustee;

     (ii) no trustee hereunder shall be personally liable by reason of any act or
omission of any other trustee hereunder; and

     (iii) the Trustee may at any time accept the resignation of or remove any
separate trustee or co-trustee, and the Trustee shall, following the waiver or cure
of the Event of Default pursuant to the terms hereof remove any separate trustee or
co-trustee appointed pursuant to Section 16.14(a) in connection with such
Event of Default.

     (c) Any notice, request or other writing given to the Trustee shall be deemed to have
been given to each of the then separate trustees and co-trustees, as effectively as if given
to each of them. Every instrument appointing any separate trustee or co-trustee shall refer
to this Indenture and the conditions of this Section 16.14. Each separate trustee
and co-trustee, upon its acceptance of the trusts conferred, shall, subject to the
provisions of this Section 16.14, be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately, as may be
provided therein, subject to all the provisions of this Indenture specifically including
every provision of this Indenture relating to the conduct of, affecting the liability of, or
affording protection or rights (including the rights to compensation, reimbursement and
indemnification hereunder) to the Trustee. Every such instrument shall be filed with the
Trustee.

     (d) Any separate trustee or co-trustee appointed pursuant to Section 16.14(a)
may at any time constitute the Trustee, in the jurisdiction or jurisdictions set forth in
Section 16.14(a), its agent or attorney-in-fact in such jurisdiction or
jurisdictions with full power and authority, to the

89

 

extent not prohibited by law in such jurisdiction or jurisdictions, to do any lawful
act under or in respect of this Indenture on its behalf and in its name. If any separate
trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee to the extent permitted by law, without the appointment of a new or successor
trustee.

YINGLI GREEN ENERGY HOLDING COMPANY LIMITED

10.0% GUARANTEED SENIOR SECURED CONVERTIBLE NOTE DUE 2012

     This Note is one of a duly authorized issue of Notes of the Company, designated as its

thereunder of the Trustee, the Company and the holders of the Notes.

     In case an Event of Default shall have occurred and be continuing, the principal of and

redemption or repurchase thereof, (iv) change the obligation of the Company to repurchase any Note

A-4

 

amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes
waive any past Default or Event of Default under the Indenture and its consequences except (A) a
default in the payment of Interest on, or the principal of, or any Repurchase Amount in respect of
the Notes, (B) a failure by the Company to convert any Notes into Common Stock of the Company, (C)
a default in the payment of the Purchase Price pursuant to Section 3.02 of the Indenture or (D) a
default in respect of a covenant or provisions of the Indenture which under Article 8 of the
Indenture cannot be modified or amended without the consent of the holders of each or all Notes
then outstanding or affected thereby. Any such consent or waiver by the holder of this Note
(unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and
upon all future holders and owners of this Note and any Notes which may be issued in exchange or
substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or
such other Notes.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and Interest on this Note at the place, at the respective times, at the rate and in
the coin or currency herein prescribed.

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

     The Notes are issuable in fully registered form, without coupons, in denominations of $100,000
principal amount and any multiple of $1,000 thereafter. At the office or agency of the Company
referred to on the face hereof, and in the manner and subject to the limitations provided in the
Indenture, without payment of any service charge but with payment of a sum sufficient to cover any
tax, assessment or other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of
Notes of any other authorized denominations.

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

     In the event that the Company shall be required to commence a Change of Control Offer or a
Termination of Trading Offer, the Company shall mail to all holders of record of the Notes a notice
which states the terms of such Offer to Purchase and the circumstances and relevant facts regarding
such event. Each holder shall have the right to accept such offer and require the Company to
repurchase all or any portion of such holder’s Notes in cash equal to the Repurchase Amount.

     Holders electing to have a Note purchased pursuant to a Offer to Purchase shall deliver to the
Company such Note with the form entitled “Purchase Notice” on the reverse thereof duly
completed, together with the Note, duly endorsed for transfer, at any time prior to the close of
business on the Business Day immediately preceding the Purchase Date, and shall deliver the Notes
to the Trustee (or other paying agent appointed by the Company) as set forth in the Indenture.

     If the Purchase Date is on or after a record date for the payment of interest and on or before
the related Interest Payment Date, any accrued and unpaid Interest shall be paid to the Person in
whose name a Note is registered at the close of business on such record date for the payment of
interest, and no further Interest shall be payable to holders who tender Notes pursuant to the
Offer to Purchase. The Notes will be subject to repurchase in a minimum principal amount of
$100,000 and integral multiples of $1,000 in excess thereof.

     The holder shall be entitled to withdraw any Purchase Notice if the Company, or the Paying
Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram,
facsimile transmission or letter setting forth the name of the holder, the principal amount of this
Note (or portions

A-5

 

thereof) the holder delivered for purchase and a statement that such holder is withdrawing his
election to have this Note purchased.

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

     Subject to the foregoing paragraph and occurrence of certain events and in compliance with the
provisions of the Indenture, prior to the final maturity date of the Notes, the holder hereof has
the right, at its option, to convert each $100,000 principal amount of the Notes into 17,699 shares
of the Company’s Common Stock (a conversion price of approximately $5.65 per share), as such shares
shall be constituted at the date of conversion and subject to adjustment from time to time as
provided in the Indenture, upon surrender of this Note with the form entitled “Conversion
Notice” on the reverse thereof duly completed, and manually signed, together with this Note
duly endorsed for transfer, accompanied by the funds, if any, required by Section 15.02 of the
Indenture, such notice also stating the name or names (with address or addresses) in which the
certificate or certificates for shares of Common Stock which shall be issuable on such conversion
shall be issued, and accompanied by transfer or similar taxes, if required pursuant to Section
15.07 of the Indenture.

     No adjustment in respect of interest on any Note converted or dividends on any shares issued
upon conversion of such Note will be made upon any conversion except as set forth in the next
sentence. If this Note (or portion hereof) is surrendered for conversion during the period from
the close of business on any record date for the payment of interest to the close of business on
the Business Day preceding the following Interest Payment Date, this Note (or portion hereof being
converted) must be accompanied by payment, in immediately available funds or other funds acceptable
to the Company, of an amount equal to the interest otherwise payable on such Interest Payment Date
on the principal amount being converted; provided that no such payment shall be required (1) if the
Company has specified a Purchase Date that is during such period or (2) to the extent of any
overdue Interest, if any overdue interest exists at the time of conversion with respect to such
Note.

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

     A Note in respect of which a holder is exercising its right to require repurchase upon a
Change of Control Offer or Termination of Trading Offer on a Purchase Date may be converted only if
such holder withdraws its election to exercise either such right in accordance with the terms of
the Indenture.

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

     The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and
any Registrar may deem and treat the registered holder hereof as the absolute owner of this Note
(whether or not this Note shall be overdue and notwithstanding any notation of ownership or other
writing hereon made by anyone other than the Company or any Registrar) for the purpose of receiving
payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and
neither the Company nor the

A-6

 

Trustee nor any other authenticating agent nor any paying agent nor other conversion agent nor
any Registrar shall be affected by any notice to the contrary. All payments made to or upon the
order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge
liability for monies payable on this Note.

     The Trustee under the Indenture, in its individual or any other capacity, may enter into
business transactions with the Company, its Affiliates or any entity related thereto without
accounting for any profit.

     No recourse for the payment of the principal of or Interest on this Note, or for any claim
based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant
or agreement of the Company in the Indenture or any supplemental indenture or in any Note, or
because of the creation of any indebtedness represented thereby, shall be had against any
incorporator, shareholder, employee, agent, officer or director or subsidiary, as such, past,
present or future, of the Company or of any successor corporation, either directly or through the
Company or any successor corporation, whether by virtue of any constitution, statute or rule of law
or by the enforcement of any assessment or penalty or otherwise, all such liability being, by
acceptance hereof and as part of the consideration for the issue hereof, expressly waived and
released.

     This Note shall be governed by and construed in accordance with the laws of New York.
