If such Record Date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after such Record Date, but only the Holders of record at the close of business on such Record Date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities shall be computed as of such Record Date. Promptly and in any case not later than ten (10) days after setting a Record Date, the Company shall notify the Trustee and the Holders of such Record Date.

     (e) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Security shall bind each subsequent Holder of such Security, and each Holder of any Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, with respect to anything done or suffered to be done by the Trustee or the Company in reliance upon such action, whether or not notation of such action is made upon such Security.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 2.11. Payment of Interest; Interest Rights Preserved.

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

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

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security, the date of the proposed payment and the Special Record Date, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause. The Special Record Date for the payment of such Defaulted Interest shall be not more than fifteen (15) days and not less than ten (10) days prior to the date of the proposed payment and not less than fifteen (15) days after the receipt by the Trustee of the notice of the proposed payment. The Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at such Holder’s address as it appears in the Security Register, not less than ten (10) days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

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

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

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

     Section 2.12. Persons Deemed Owners.

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

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

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

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

ARTICLE 3
Satisfaction and Discharge

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

     (a) either

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

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

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

     (A) have become due and payable, or

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

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

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

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

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

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

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

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

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

     Section 3.03. Paying Agent to Repay Moneys Held. Upon the satisfaction and discharge of this Indenture, all moneys then held by any Paying Agent of the Securities (other than the Trustee) shall, upon demand of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such moneys.

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

ARTICLE 4
Remedies

     Section 4.01. Events of Default. “Event of Default”, wherever used herein, means with respect to the Securities any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 4.05. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, be for the ratable benefit of the Holders of the Securities, in respect of which Securities such judgment has been recovered.

     Section 4.06. Application of Money Collected. Any money collected by the Trustee with respect to Securities pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium, if any, or interest, if any, upon presentation of the Securities and the notation thereon of the payment, if only partially paid, and upon surrender thereof, if fully paid:

     First: To the payment of all amounts due the Trustee under Section 5.07 hereof.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 5.09. Corporate Trustee Required; Eligibility.

     (iii) the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, subject to Section 4.14, any Holder who has been a bona fide Holder of a Security for at least 6 months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Securities or, in the case of this clause (iii), with respect to the Securities.

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

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

Each notice shall include the name of the successor Trustee and the address of its principal Corporate Trust Office.

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

     Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to above.

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

     Section 5.12. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided that such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor Trustee by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

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

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

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

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

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

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

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

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

Any failure of the Trustee to give such notice, or any defect therein, shall not in any way impair or affect the validity of any such supplemental indenture.

ARTICLE 8
Covenants

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

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

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

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

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

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

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

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

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

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

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

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

     Section 8.05. Corporate Existence. Subject to Article 6, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

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

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

ARTICLE 9
Conversion of Securities

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

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

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

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

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

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

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

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

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

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

     (a) In case the Company shall pay or make a dividend or other distribution on any class of Capital Stock of the Company payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective (subject to paragraph (l) of this Section 9.04) immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. In no event shall this paragraph (a) apply in the case of an ordinary dividend.

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

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

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

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

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

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

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

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

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

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

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

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

     To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (20) days and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall give notice of the increase to the Holders of Securities in the manner provided in Section 1.06 at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

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

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

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

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

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

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

     (b) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall be required, and as soon as practicable after it is required, such notice shall be provided by the Company to all Holders in accordance with Section 1.06.

     Neither the Trustee nor the Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any Holder of any Securities to which this Article 9 applies, desiring inspection thereof at its office during normal business hours. Unless and until a Responsible Officer of the Trustee and Conversion Agent receive notice of an adjusted Conversion Rate, the Trustee and the Conversion Agent may rely without inquiry on the Conversion Rate most recently in effect.

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

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

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

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

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

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

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

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

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

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

     Section 9.09. Reserved.

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

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

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

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

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

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

     Section 9.13. Automatic Conversion.

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

     (b) At the request and expense of the Company, the Trustee shall mail or cause to be mailed to each Holder of Outstanding Securities a notice (the “Automatic Conversion Notice”), such notice to be prepared by the Company, of an Automatic Conversion not more than thirty (30) days but not less than twenty (20) days prior to the date on which the Securities will be Automatically Converted (the “Automatic Conversion Date”). If the Company gives such notice, it shall also deliver a copy of such Automatic Conversion Notice to the Trustee. Such mailing shall be by first class mail. Such notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Security shall not affect the validity of the proceedings for the Automatic Conversion of any other Security.

     (c) Each Automatic Conversion Notice shall state:

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

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

     (3) the Automatic Conversion Date,

     (4) the Make-Whole Payment,

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

     (6) the Conversion Rate then in effect.

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

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

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

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

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

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

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

ARTICLE 10
Make-Whole Payment

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

ARTICLE 11
Holders Lists And Reports By Trustee And Company; Non-Recourse

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

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

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

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

     Section 11.02. Preservation of Information.

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

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

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

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

     Section 11.04. Reports by Trustee.

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

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

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

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

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

ARTICLE 12
Subordination

     Section 12.01. Agreement to Subordinate.

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

     Section 12.02. Liquidation, Dissolution, Bankruptcy.

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

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

     Section 12.03. Default on Senior Debt.

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

     Section 12.04. Acceleration of Payment of Securities.

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

     Section 12.05. When Distribution Must Be Paid Over.

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

     Section 12.06. Subrogation.

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

     Section 12.07. Relative Rights.

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

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

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

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

     Section 12.08. Subordination May Not Be Impaired by Company.

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

     Section 12.09. Rights of Trustee and Paying Agent.

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

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

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

     Section 12.10. Distribution or Notice to Representative.

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

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

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

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

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

     Section 12.13. Trustee Entitled to Rely.

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

     Section 12.14. Trustee’s Compensation Not Prejudiced.

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

     Section 12.15. Trustee to Effectuate Subordination.

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

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

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

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

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

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

     Section 13.01. Right to Require Repurchase.

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

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

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

     Each Repurchase Notice shall state:

     (1) the Repurchase Date,

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

     (3) the Repurchase Price,

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

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

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

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

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

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

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

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

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

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

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

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

     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed; all as of the date first above written.
