Debentures not to exceed the aggregate principal amount of $46,936,000 (except pursuant to Section 2.05, Section 2.06 and Section 14.02(f) hereof) upon the execution of this Indenture, or from time to time thereafter, may be executed by the Company and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Debentures to or upon the written order of the Company, signed by its Chief Executive Officer, President or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title “Vice President”), the Treasurer or any Assistant Treasurer or the Secretary or Assistant Secretary, without any further action by the Company hereunder.

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

Any of the Debentures may have such letters, numbers or other marks of identification and such notations, legends, endorsements or changes as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Debentures may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Debentures are subject.

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

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

Section 2.03.Date And Denomination Of Debentures;Payments Of Interest.

(a) The Debentures shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Debenture shall be dated the date of its authentication and shall bear Interest from the date specified on the face of the form of Debenture attached asExhibit Ahereto. Interest on the Debentures shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

(b) The Person in whose name any Debenture (or its Predecessor Debenture) is registered on the Debenture Register at the close of business on any record date with respect to any interest payment date shall be entitled to receive the Interest payable on such interest payment date, except that the Interest payable upon repurchase will be payable to the Person to whom principal is payable pursuant to such repurchase (unless the Designated Event Repurchase Date falls after a record date and on or prior to the corresponding interest payment date, in which case the full semi-annual payment of Interest becoming due on such interest payment date shall be payable to the Holders of such Debentures registered as such on the corresponding record date). Interest shall be payable at an office maintained by the Company for such purposes in the Borough of Manhattan, City of New York, which shall initially be an office or agency of the Trustee. The Company shall pay Interest (i) on any Debentures in certificated form by check mailed to the address of the Person entitled thereto as it appears in the Debenture Register (or upon written notice, by wire transfer in immediately available funds, if such Person is entitled to Interest on aggregate principal in excess of $2 million) or (ii) on any Global Debenture by wire transfer of immediately available funds to the account of the Depositary or its nominee. The term “record date” with respect to any interest payment date shall mean the March 1 or September 1 preceding the applicable March 15 or September 15 interest payment date, respectively.

(c) Any Interest on any Debenture that is payable, but is not paid or duly provided for, on any March 15 or September 15, pursuant to the terms set forth herein (“Defaulted Interest”) shall forthwith cease to be payable to the Debentureholder on the relevant record date by virtue of his having been such Debentureholder, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in Section 2.03(c)(i) and Section 2.03(c)(ii) below:

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

(ii) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Debentures may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 2.03(c)(ii), such manner of payment shall be deemed practicable by the Trustee.

Section 2.04.Execution of Debentures.The Debentures shall be signed in the name and on behalf of the Company by the manual or facsimile signature of its Chief Executive Officer, President or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title “Vice President”). Only such Debentures as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Debenture attached asExhibit Ahereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 15.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Debenture executed by the Company shall be conclusive evidence that the Debenture so authenticated has been duly authenticated and delivered hereunder and that the Debentureholder is entitled to the benefits of this Indenture.

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

Section 2.05.Exchange and Registration of Transfer of Debentures;Restrictions on Transfer.

(a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 4.02 being herein sometimes collectively referred to as the “Debenture Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Debentures and of transfers of Debentures. The Debenture Register shall be in written form or in any form capable of being converted into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Debenture Registrar” for the purpose of registering Debentures and transfers of Debentures as herein provided. The Company may appoint one or more co-registrars in accordance with Section 4.02.

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

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

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

All Debentures presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company or the Debenture Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Debentures shall be duly executed by the Debentureholder thereof or his attorney duly authorized in writing.

No service charge shall be made to any Debentureholder for any registration of, transfer or exchange of Debentures, but the Company and the Debenture Registrar may require payment by the Debentureholder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Debentures.

Neither the Company nor the Trustee nor any Debenture Registrar shall be required to exchange or register a transfer of any Debentures or portions thereof (a) tendered for repurchase (and not withdrawn) pursuant to ARTICLE 3, or (b) surrendered for conversion pursuant to ARTICLE 14.

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

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

(ii) Notwithstanding any other provision in this Indenture, no Global Debenture may be exchanged in whole or in part for Debentures registered, and no transfer of a Global Debenture in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (1) the Depositary (I) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Debenture and a successor depositary has not been appointed by the Company within ninety (90) days or (II) has ceased to be a clearing agency registered under the Exchange Act and a successor clearing agency has not been appointed by the Company within ninety (90) days, (2) an Event of Default has occurred and is continuing or (3) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Debentures represented by Global Debentures. Any Global Debenture exchanged pursuant to clause (A) or (B) above shall be so exchanged in whole and not in part and any Global Debenture exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Company. Any Debenture issued in exchange for a Global Debenture or any portion thereof shall be a Global Debenture;providedthat any such Debenture so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Debenture.

(iii) Securities issued in exchange for a Global Debenture or any portion thereof pursuant to Section 2.05(b)(ii) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Debenture or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Debenture to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Debenture Registrar. With regard to any Global Debenture to be exchanged in part, either such Global Debenture shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Debenture, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Debenture issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in Section 2.05(b)(ii) above, the Company will promptly make available to the Trustee a reasonable supply of certificated Debentures in definitive, fully registered form, without interest coupons.

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

(vi) At such time as all interests in a Global Debenture have been repurchased, converted, canceled or exchanged for Debentures in certificated form, such Global Debenture shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Debenture is repurchased, converted, canceled or exchanged for Debentures in certificated form, the principal amount of such Global Debenture shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Debenture, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) The Company and the Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Debentures, with respect to performance by the Depositary or any Agent Members of their respective obligations under the rules and procedures governing their operations or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Debentures. All notices and communications to be given to the Debentureholder and all payments to be made to Debentureholders under the Debentures shall be given or made only to or upon the order of the registered Debentureholders (which shall be the Depositary or its nominee in the case of a Global Debenture). The rights of beneficial owners in any Global Debenture shall be exercised only through the Depositary subject to the customary procedures of the Depositary. The Company and the Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

The Company and the Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Debenture (including any transfers between or among Agent Members in any Global Indenture) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.06.Mutilated, Destroyed, Lost or Stolen Debentures.In case any Debenture shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Debenture, bearing a number not contemporaneously Outstanding, in exchange and substitution for the mutilated Debenture, or in lieu of and in substitution for the Debenture so destroyed, lost or stolen. In every case, the applicant for a substituted Debenture shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Debenture and of the ownership thereof.

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

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

Section 2.07.Temporary Debentures.Pending the preparation of Debentures in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Debentures (printed or lithographed). Temporary Debentures shall be issuable in any authorized denomination, and substantially in the form of the Debentures in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Debentures, all as may be determined by the Company. Every such temporary Debenture shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Debentures in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating agent Debentures in certificated form and thereupon any or all temporary Debentures may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Debentures an equal aggregate principal amount of Debentures in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Debentures shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Debentures in certificated form authenticated and delivered hereunder.

Section 2.08.Cancellation of Debentures.All Debentures surrendered for the purpose of payment, repurchase, conversion, exchange or registration of transfer shall, if surrendered to the Company or any paying agent or any Debenture Registrar or the Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Debentures shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Debentures in accordance with its customary procedures. If the Company shall acquire any of the Debentures, such acquisition shall not operate as a repurchase or satisfaction of the indebtedness represented by such Debentures unless and until the same are delivered to the Trustee for cancellation.

Section 2.09.CUSIP Numbers.The Company in issuing the Debentures may use “CUSIP” numbers (if then generally in use). The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE 3
Repurchase Of Debentures

Section 3.01.Repurchase at Option of Holders Upon a Designated Event.

(a) If there shall occur a Designated Event at any time prior to maturity of the Debentures, then each Debentureholder shall have the right, at such Debentureholder’s option, to require the Company to repurchase all of such Debentureholder’s Debentures, or any portion thereof that is a multiple of $1,000 principal amount, on a date designated by the Company (the “Designated Event Repurchase Date”) that is not less than twenty (20) nor more than thirty-five (35) Business Days after the date of the Designated Event Notice for such Designated Event (or, if such day is not a Business Day, the next succeeding Business Day) at a repurchase price equal to one hundred percent (100%) of the principal amount thereof, together with accrued and unpaid Interest to, but excluding, the Designated Event Repurchase Date;providedthat if such Designated Event Repurchase Date falls after a record date and on or prior the corresponding interest payment date, then the Interest payable on such interest payment date shall be paid to the holders of record of the Debentures on the applicable record date instead of the holders surrendering the Debentures for repurchase.

(b) On or before the 20th day after the occurrence of a Designated Event, the Company or at its written request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree in writing to a shorter period), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed to all holders of record on the date of the Designated Event a notice (the “Designated Event Notice”) of the occurrence of such Designated Event and of the repurchase right at the option of the holders arising as a result thereof;providedthat if the Company shall give such Designated Event Notice, it shall also give written notice of the Designated Event to the Trustee by first class mail. Such Designated Event Notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Debentureholder receives such Designated Event Notice. In any case, failure to give such notice by mail or any defect in the notice to the Debentureholder shall not affect the validity of the Designated Event Notice for the Debentureholder of any other Debenture. Concurrently with the mailing of

any such Designated Event Notice, the Company shall issue a press release announcing such Designated Event, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Designated Event Notice or any of the proceedings for the repurchase of any Debenture relating thereto. If the Company shall give such notice, the Company shall also deliver a copy of the Designated Event Company Notice to the Trustee at such time as it is mailed to Debentureholders. Concurrently with the mailing of any Designated Event Notice, the Company shall issue a press release announcing such Designated Event referred to in the Designated Event Notice, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Designated Event Notice or any proceedings for the repurchase of any Debenture that any Debentureholder may elect to have the Company repurchase as provided in this Section 3.01.

Each Designated Event Notice shall specify the circumstances constituting the Designated Event, the Designated Event Repurchase Date, the price at which the Company shall be obligated to repurchase Debentures, that the Debentureholder must exercise the repurchase right on or prior to the close of business on the Designated Event Repurchase Date (the “Designated Event Expiration Time”), that the Debentureholder shall have the right to withdraw any Debentures surrendered prior to the Designated Event Expiration Time, if the Debentures are then convertible, that Debentures as to which an Option to Elect Repurchase Upon a Designated Event has been given may be converted only if the Option to Elect Repurchase Upon a Designated Event is withdrawn in accordance with the terms of this Indenture, a description of the procedure that any Debentureholder must follow to exercise such repurchase right and to withdraw any surrendered Debentures, the place or places where the Debentureholder is to surrender such Debentureholder’s Debentures, the amount of Interest accrued and unpaid on each Debenture to the Designated Event Repurchase Date and the CUSIP number or numbers of the Debentures (if then generally in use).

The Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default.

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

by the Debentures, plus one percent (1%) and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other amounts due the Trustee under Section 7.06. Until such demand by the Trustee, the Company may pay the principal of and Interest on the Debentures to the registered holders, whether or not the Debentures are overdue.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Debentures under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Debentures, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Debentures shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and Interest owing and unpaid in respect of the Debentures, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Debentureholders allowed in such judicial proceedings relative to the Company or any other obligor on the Debentures, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 7.06, and to take any other action with respect to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, and, unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Debentureholders 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 Debentureholders, to pay to the Trustee any amount due it for reasonable

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

Section 6.06.Remedies Cumulative And Continuing.Except as provided in Section 2.06, all powers and remedies given by this ARTICLE 6 to the Trustee or to the Debentureholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Debentures, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Debentureholder to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given by this ARTICLE 6 or by law to the Trustee or to the Debentureholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Debentureholders.

ARTICLE 7
The Trustee

In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

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

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

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and

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

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

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the holders of not less than a majority in principal amount of the Debentures at the time Outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

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

(g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless it shall have been notified in writing of such Event of Default by the Company or the holders of at least 10% in aggregate principal amount of the Debentures.

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

Section 7.02.Reliance on Documents, Opinions, Etc.Except as otherwise provided in Section 7.01:

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

(b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

(c) the Trustee may consult with counsel of its own selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

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

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

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

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

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

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

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

Section 7.03.No Responsibility For Recitals, Etc.The recitals contained herein and in the Debentures (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture, of the Debentures or of the Escrow Agreement. The Trustee shall not be accountable for the use or application by the Company of any Debentures or the proceeds of any Debentures authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.

Section 7.04.Trustee, Paying Agents, Conversion Agents or Debenture Registrar May Own Debentures.The Trustee, any paying agent, the Conversion Agent or Debenture Registrar, in its individual or any other capacity, may become the owner or pledgee of Debentures with the same rights it would have if it were not Trustee, paying agent, Conversion Agent or Debenture Registrar.

Section 7.05.Monies to Be Held in Trust.Subject to the provisions of Section 12.04, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee.

Section 7.06.Compensation and Expenses of Trustee.The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence, willful misconduct, recklessness or bad faith. The Company also covenants to indemnify the Trustee and any predecessor Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, liability, damage, claim or reasonable expense including taxes (other than franchise taxes and taxes based on the income of the Trustee) incurred without negligence, willful misconduct, recklessness or bad faith on the part of the Trustee or such officers, directors, employees and agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the reasonable costs and expenses of defending themselves against any claim (whether asserted by the Company, any Debentureholder or any other Person) of liability in connection with the exercise or performance of any of its or their powers or duties hereunder. If the Company

fails to compensate or indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and advances under this Section 7.06, the Trustee’s claim shall be secured by a lien prior to that of the Debentures upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Debentures. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

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

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

Section 7.09.Eligibility of Trustee.There shall at all times be a Trustee hereunder that shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section 7.09 the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall resign immediately in the manner and with the effect hereinafter specified in this ARTICLE 7.

Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Debentureholders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Debentureholders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Debentureholder who has been a bona fide Holder of a Debenture or Debentures for at least six (6) months may, subject to the provisions of Section 6.09, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

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

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

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.09, any Debentureholder who has been a bona fide Holder of a Debenture or Debentures for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee;providedthat if no successor Trustee shall have been appointed and have accepted appointment sixty (60) days after either the Company or the Debentureholders has removed the Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of the Company, any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The holders of a majority in aggregate principal amount of the Debentures at the time Outstanding may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any Debentureholder, or if such Trustee so removed or any Debentureholder fails to act, the Company, upon the terms and conditions and otherwise as in Section 7.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.

(e) Notwithstanding the replacement of the Trustee pursuant to this Section 7.10, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

Section 7.11.Acceptance by Successor Trustee.Any successor trustee appointed as provided in Section 7.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Debentures, to secure any amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.11 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 7.08 and be eligible under the provisions of Section 7.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.11, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders of Debentures at their addresses as they shall appear on the Debenture Register. If the Company fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 7.12.Succession By Merger.Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto,providedthat in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09.

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

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

ARTICLE 8
The Debentureholders

Section 8.01.Action By Debentureholders.Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Debentures may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Debentureholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Debentures voting in favor thereof at any meeting of Debentureholders duly called and held in accordance with the provisions of ARTICLE 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Debentureholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Debentures, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled to take such action. The record date shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action.

Section 8.02.Proof of Execution by Debentureholders.Subject to the provisions of Section 7.01, Section 7.02 and Section 9.05, proof of the execution of any instrument by a Debentureholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Debentures shall be proved by the registry of such Debentures or by a certificate of the Debenture Registrar.

The record of any Debentureholders’ meeting shall be proved in the manner provided in Section 9.06.

Section 8.03.Who Are Deemed Absolute Owners.The Company, the Trustee, any paying agent, the Conversion Agent and any Debenture Registrar may deem the Person in whose name such Debenture shall be registered upon the Debenture Register to be, and may treat it as, the absolute owner of such Debenture (whether or not such Debenture shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Debenture Registrar) for the purpose of receiving payment of or on account of the principal of and Interest on such Debenture, for conversion of such Debenture and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor the Conversion Agent nor any Debenture Registrar shall be affected by any notice to the contrary. All such payments so made to any Debentureholder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Debenture.

Section 8.04.Company-owned Debentures Disregarded.In determining whether the holders of the requisite aggregate principal amount of Debentures have concurred in any direction, consent, waiver or other action under this Indenture, Debentures that are owned by the Company or any other obligor on the Debentures or any Affiliate of the Company or any other obligor on the Debentures shall be disregarded and deemed not to be Outstanding for the purpose of any such determination;provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Debentures that a Responsible Officer knows are so owned shall be so disregarded. Debentures so owned that have been pledged in good faith may be regarded as Outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Debentures and that the pledgee is not the Company, any other obligor on the Debentures or any Affiliate of the Company or any such other obligor.

At such time, the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of Debentures beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Debentures is greater than or equal to one hundred percent (100%) of the product of the Closing Sale Price per share of the Common Stock multiplied by the applicable Conversion Rate.

(iii) If a Fundamental Change occurs, then (A) the Company shall notify all holders of Debentures and the Trustee as promptly as practicable following (I) the date the Company publicly announces such transaction, but in no event fewer than thirty (30) Business Days prior to the anticipated effective date of such transaction, and (II) the effective date of such transaction, but in any event, within five (5) Business Days after the effective date of such transaction; and (B) the Debentures may be surrendered for conversion at any time from, and including, the thirtieth (30th) Business Day prior to the anticipated effective date of such transaction to, and including, the thirty-fifth (35th) Trading Day following such effective date;provided,however, that if the Company announces a transaction that causes the Debentures to become convertible pursuant to this Section 14.01(a)(iii), but the transaction is not consummated, then from and after the date the Company publicly announces that the transaction will not occur, the Debentures will cease to be convertible pursuant to this Section 14.01(a)(iii) on account of such transaction.

(iv) If, prior to the close of business on the Business Day immediately preceding March 15, 2013, the Company exercises its Mandatory Conversion right pursuant to Section 14.02.

(b) Notwithstanding the provisions of Section 14.01(a), at any time beginning on March 15, 2013 and until the close of business on the second Business Day immediately preceding the maturity date of the Debentures, any Debentureholder shall have the right, at such Debentureholder’s option, to convert the principal amount of its Debenture in integral multiples of $1,000 principal amount at the Conversion Rate in effect at such time, by surrender of the Debenture so to be converted in whole or in part.

(c) If (i) the Company distributes to all holders of its Common Stock rights, warrants or options entitling them (for a period expiring within forty-five (45) days of the record date for the determination of the shareholders entitled to receive such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days immediately preceding, but not including, the declaration date for such distribution, or (ii) the Company distributes to all holders of its Common Stock, assets, debt securities or rights to purchase its securities, where the Fair Market Value of such distribution per share of Common Stock exceeds five percent (5%) of the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date for such distribution, then, in either case, the Debentures may be surrendered for conversion at any time on and after the date that the Company gives notice to the holders of such distribution, which shall be not less than twenty (20) days prior to the Ex-Dividend Date for such distribution, until the earlier of the close of business on the Business Day immediately preceding, but not including, the Ex-Dividend Date or the date the Company publicly announces that such distribution will not take place;providedthat no adjustment to the Conversion Rate will be made nor will a holder of a Debenture be able to convert pursuant to this Section 14.01(c) if such holder will otherwise participate in such distribution without conversion.

Section 14.02.Mandatory Conversion.

(a) The Company may at any time on or after March 16, 2012 and until the maturity date of the Debentures, by providing not less than fifteen (15) nor more than thirty (30) days’ notice to any Debentureholder, cause such Debenture to be mandatorily converted at the Conversion Rate then in effect (a “Mandatory Conversion”);providedthat the Company may exercise this right only if the Closing Sale Price per share of the Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price for at least twenty (20) Trading Days (whether or not consecutive) in a period of thirty (30) consecutive Trading Days, ending on the Trading Day prior to the date the Company gives such notice of its election to cause a Mandatory Conversion (by press release as described in Section 14.02(b);provided, further,howeverthat any such Mandatory Conversion of less than all of the then outstanding Debentures shall be on a pro-rata basis with respect to the Debentures held by each Debentureholder.

(b) To exercise its right to call a Mandatory Conversion, the Company shall issue a press release prior to the close of business on the first (1st) Trading Day following any date on which the conditions described in Section 14.02(a) are met, announcing such election by the Company to call a Mandatory Conversion. The Company shall also give prompt written notice to all of the Debentureholders (not more than five (5) Business Days after the date of the press release) of the election to call a Mandatory Conversion. The Conversion Date of such Mandatory Conversion will be a date selected by the Company (the “Mandatory Conversion Date”) and will be no more than thirty (30) days nor less than fifteen (15) days after the date on which the Company issues the press release described in this Section 14.02(b).

(c) In addition to any information required by applicable law or regulation, the press release and notice of Mandatory Conversion described in this Section 14.02 shall state, as appropriate:

(i) the Mandatory Conversion Date;

(ii) the Conversion Rate then in effect;

(iii) the aggregate principal amount of the Debentures to be converted; and

(iv) that Interest on the Debentures to be converted will cease to accrue on the Mandatory Conversion Date.

(d) Notwithstanding the foregoing, the Company may only exercise its right to Mandatory Conversion if (i) it has sufficient shares of Common Stock available for issuance upon conversion of the Debentures called for in any Mandatory Conversion contemplating payment of the Conversion Consideration in Common Stock and it is able to make any cash payment that it would be required to make upon conversion of the Debentures called for Mandatory Conversion in lieu of fractional shares, Defaulted Interest or otherwise, and (ii) the shares of Common Stock issuable upon conversion of the Debentures (including any Mandatory Conversion Additional Payment issuable pursuant to Section 14.02(e), if applicable) contemplating payment of the Conversion Consideration in Common Stock are registered by the Company for resale by the Holder thereof on a shelf registration statement filed by the Company with the Commission and such registration statement has been declared effective by the Commission or is automatically effective and is available for use, and the Company expects such shelf registration statement to remain effective and available for use from the date of the notice of Mandatory Conversion until thirty (30) days following the date of the Mandatory Conversion.

(e) On and after the Mandatory Conversion Date, Interest shall cease to accumulate on the Debentures to be converted, all rights of holders of such Debentures shall terminate and all such Debentures shall automatically convert at the applicable Conversion Rate into the right to receive the Conversion Consideration.

(f) If the Company elects to cause a Mandatory Conversion, the Company will be required to make an additional payment (“Mandatory Conversion Additional Payment”) on the Debentures on the Mandatory Conversion Date. Such Mandatory Conversion Additional Payment with respect to the Debentures subject to Mandatory Conversion will, notwithstanding Section 14.04, be payable in cash on the Mandatory Conversion Date and shall be equal to the total value of the aggregate amount of Interest that would have accrued and become payable on such Debentures from March 26, 2010 through and including March 15, 2014, less any Interest already paid on the Debentures. The notice of the Mandatory Conversion shall also state the amount of the Mandatory Conversion Additional Payment.

Section 14.03.Conversion After Exercise of Option to Elect to Repurchase Upon a Designated Event; No Stockholder Rights. Notwithstanding any other provision of this ARTICLE 14, a Debenture in respect of which a Debentureholder is electing to exercise its Option to Elect to Repurchase Upon a Designated Event pursuant to Section 3.01 may be converted only if such Debentureholder withdraws its election in accordance with Section 3.01(b). A Debentureholder is not entitled to any rights of a holder of Common Stock until (i) such Debentureholder has converted its Debentures to Common Stock, (ii) on and after the Mandatory Conversion Date, or (iii) otherwise to the extent such Debentures are deemed to have been converted to Common Stock under this ARTICLE 14.

Section 14.04.Conversion Procedure and Payment Upon Conversion.

(a) If a Debenture is surrendered for conversion pursuant to Section 14.01 or Section 14.02, then:

(i) the Company shall deliver, through the Conversion Agent, the following Conversion Consideration to such Debentureholder:

(1) if Physical Settlement applies to such conversion, a number of fully paid and non-assessable shares of Common Stock equal to the product of the principal amount of such Debenture to be converted (expressed in thousands) multiplied by the Conversion Rate in effect on the Conversion Date of such conversion;provided, however, that if such product is not a whole number, then the Company will pay a cash amount in lieu of issuing any fractional share, which cash amount shall paid in accordance with Section 14.05;

(2) if Cash Settlement applies to such conversion, a cash amount equal to the product of the principal amount of such Debenture (expressed in thousands) multiplied by the Conversion Value applicable to such conversion; and

(3) if Combination Settlement applies to such conversion,

a. a cash amount equal to the lower of (i) the Fixed Cash Amount applicable to such conversion and (ii) the Conversion Value applicable to such conversion; and

b. a number of shares of Common Stock, if any, equal to the sum, for each Trading Day in the Observation Period applicable to such conversion, of one-twentieth (1/20th) of a fraction (i) whose numerator is the excess, if any, of (1) the product of the Conversion Rate in effect on such Trading Day and the VWAP per share of Common Stock on such Trading Day over (2) the Fixed Cash Amount applicable to such conversion and (ii) whose denominator is such VWAP per share of Common Stock;provided, however,that if such sum is not a whole number, then the Company will pay a cash amount in lieu of issuing any fractional share, which cash amount shall paid in accordance with Section 14.05;

(ii) except as provided in Section 14.07(i), the Conversion Consideration due upon such conversion shall be delivered by the Company as follows: (1) if Physical Settlement applies to such conversion, on the third (3rd) Trading Day following the Conversion Date of such conversion (or, if earlier, the maturity date of the Debentures); and (2) in all other cases, on the third (3rd) Trading Day following the final Trading Day of the Observation Period applicable to such conversion;

(iii) if Physical Settlement applies to such conversion, then the person in whose name the certificate representing the shares of Common Stock constituting the Conversion Consideration due upon such conversion shall be treated as a stockholder of record of such shares as of the close of business on the Conversion Date of such conversion;

(iv) if Combination Settlement applies to such conversion, then the person in whose name the certificate representing the shares of Common Stock, if any, constituting the Conversion Consideration due upon such conversion shall be treated as a stockholder of record of such

shares of Common Stock, without duplication, as follows: as of the close of business on each Trading Day (the “Relevant Trading Day”) during the Observation Period applicable to such conversion, such person shall be treated as a stockholder of record of a number of shares of Common Stock equal to the sum, for each Trading Day in such Observation Period occurring on or before such Relevant Trading Day, of one-twentieth (1/20th) of a fraction (A) whose numerator is the excess, if any, of (1) the product of the Conversion Rate in effect on such Trading Day and the VWAP per share of Common Stock on such Trading Day over (2) the Fixed Cash Amount applicable to such conversion and (B) whose denominator is such VWAP per share of Common Stock (except that if such sum is not a whole number, then the fractional portion of such sum shall be ignored); and

(v) on and after the Conversion Date for such conversion, all rights of the Debentureholder with respect to such Debenture shall terminate, other than the right to receive the Conversion Consideration due upon such conversion in accordance with this Indenture.

The Settlement Method applicable to each conversion of a Debenture pursuant to Section 14.01 or Section 14.02, as the case may be, shall be determined in accordance with Section 14.04(b).

(b) If a Debenture is surrendered for conversion in accordance with Section 14.01 or Section 14.02, as the case may be, then, unless the Conversion Date of such conversion is on or after the Irrevocable Net Share Settlement Election Date, if any, the Company shall, no later than the second (2nd) scheduled Trading Day immediately after such Conversion Date, provide written notice (the “Settlement Method Election Notice”) to the Debentureholder surrendering such Debenture for conversion and the Conversion Agent, through the Trustee, of whether the Conversion Consideration due upon such conversion shall be determined pursuant to Section 14.04(a)(i)(1) (a “Physical Settlement”), Section 14.04(a)(i)(2) (a “Cash Settlement”) or Section 14.04(a)(i)(3) (a “Combination Settlement”), which Settlement Method Election Notice shall also state, in the case of Combination Settlement, the maximum amount of cash (excluding cash, if any, payable in lieu of any fractional share) due upon such conversion per $1,000 principal amount of such Debenture (such maximum cash amount per $1,000 principal amount, the “Fixed Cash Amount”);provided,however, that the decision regarding the type of Settlement Method to be used shall be in the Company’s sole discretion;provided further,however, that:

(i) if the Company is required to provide a Settlement Method Election Notice for such conversion pursuant to this Section 14.04(b) and fails to do so in accordance with this Section 14.04(b), then Combination Settlement, with an Fixed Cash Amount equal to one thousand dollars ($1,000), shall apply to such conversion; or

(ii) unless the Company shall have theretofore made an Irrevocable Net Share Settlement Election, the Company may, prior to the close of business on the Business Day immediately preceding March 15, 2013, deliver a one-time notice (the “Free Convertibility Period Settlement Method Election Notice”) to holders of Debentures, the Trustee and the Conversion Agent, irrevocably designating the Settlement Method that shall apply to each and every conversion of a Debenture whose Conversion Date occurs on or after the close of business on the Business Day immediately preceding March 15, 2013; if the Company so provides a Free Convertibility Period Settlement Method Election Notice, then (I) the Company cannot thereafter rescind such notice; and (II) the Company need not, and may not, provide a Settlement Method Election Notice with respect to any conversion of a Debenture whose Conversion Date occurs on or after the close of business on the Business Day immediately preceding March 15, 2013;

(iii) if, on the close of business on the Business Day immediately preceding March 15, 2014, the Company has not theretofore made an Irrevocable Net Share Settlement Election and has not theretofore provided a Free Convertibility Period Settlement Method Election Notice in accordance with Section 14.04(b)(ii), then (A) Combination Settlement, with a Fixed Cash Amount equal to one thousand dollars ($1,000), shall apply to each and every conversion of any Debenture whose Conversion Date is on or after the close of business on the Business Day immediately preceding March 15, 2013; and (B) the Company need not, and may not, provide a Settlement Method Election Notice with respect to any conversion of a Debenture whose Conversion Date occurs on or after the close of business on the Business Day immediately preceding March 15, 2013; and

(iv) the Company shall have the right, in its sole discretion and without the consent of any Debentureholder, to irrevocably elect (an “Irrevocable Net Share Settlement Election”), by notice to all Debentureholders, the Trustee and the Conversion Agent, promptly at any time prior to the close of business on the Business Day immediately preceding March 15, 2013, that Combination Settlement, with an Fixed Cash Amount equal to one thousand dollars ($1,000), apply to each and every conversion of any Debenture whose Conversion Date is on or after the date (the “Irrevocable Net Share Settlement Election Date”) the Company provides such notice, which election, once given, shall be irrevocable;provided,however, that the Company shall have the right to irrevocably renounce its right to make an Irrevocable Net Share Settlement Election by notifying holders of Debentures, the Trustee and the Conversion Agent at any time prior to the earlier of the (A) the close of business on the Business Day immediately preceding March 15, 2013 and (B) the Company’s exercise of the Irrevocable Net Share Settlement

Election, in which case no Irrevocable Net Share Settlement Election is permitted to be made after such notice; if the Company has duly made an Irrevocable Net Share Settlement Election, then the Company need not, and may not, thereafter provide a Settlement Method Election Notice in respect of any conversion of a Debenture or a Free Convertibility Period Settlement Method Election Notice.

Notwithstanding anything in this Indenture or the Debentures to the contrary, if the Conversion Dates of two (2) or more conversions of any Debentures occur on the same Trading Day, then the same Settlement Method shall apply to each of such conversions.

(c) Upon conversion of a Debenture in accordance with Section 14.01 or Section 14.02, as the case may be, the Debentureholder of such Debenture shall not be entitled to receive, on account of such conversion, any separate cash payment for accrued and unpaid Interest thereon, except as provided in the immediately following sentence. If a Debentureholder surrenders a Debenture for conversion after the close of business on a Record Date and prior to the immediately following date of Interest payment, then, notwithstanding such conversion, the Interest payable with respect to such Debenture on such date of Interest payment shall be paid on such date of Interest payment to such Debentureholder at the close of business on such Record Date;provided, however,that such Debenture, when surrendered for conversion, must be accompanied by payment to the Conversion Agent on behalf of the Company of an amount equal to the Interest payable on such date of Interest payment on the portion of such Debenture to be so converted, except that no such payment is required if either (i) the Company shall have specified a Designated Event Repurchase Date that is after such Record Date and on or prior to such Interest payment date, or (ii) the Conversion Date for such conversion is after the Record Date that immediately precedes the date of the maturity of the Debentures;provided further, however,that, if the Company shall have, prior to the Conversion Date with respect to a Debenture, defaulted in a payment of Defaulted Interest on such Debenture, then in no event shall such Debentureholder who surrenders such Debenture for conversion be required to pay such Defaulted Interest or the Interest that shall have accrued on such Defaulted Interest (it being understood that nothing in this Section 14.04(c) shall affect the Company’s obligations under ARTICLE 6).

(d) If a Debentureholder converts more than one Debenture at the same time, the number of full shares of Common Stock issuable, if any, upon such conversion shall be based on the aggregate principal amount of all Debentures converted.

(e) Upon surrender of a Debenture that is converted in part, The Company shall execute, and the Trustee shall authenticate for such Debentureholder, a new Debenture equal in principal amount to the unconverted portion of the Debenture surrendered.

(f) If the last day on which a Debenture may be converted is not a Business Day, then the Debenture may be surrendered to the Conversion Agent on the next succeeding day that is a Business Day.

(g) The Company’s delivery of the Conversion Consideration due upon any conversion of a Debenture will be deemed to satisfy in full the Company’s obligation to pay (i) the principal amount of such Debenture; and (ii) accrued and unpaid Interest to, but excluding, the Conversion Date of such conversion. As a result, accrued and unpaid Interest to, but excluding, such Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.

Section 14.05.Cash Payments in Lieu of Fractional Shares.No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same Debentureholder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of any Debenture or Debentures, the Company shall make an adjustment and payment therefor in cash at the current market price thereof to the Debentureholder. The current market price of a share of Common Stock shall be the Closing Sale Price of the Common Stock on the last Trading Day immediately preceding the day on which the Debentures (or specified portions thereof) are deemed to have been converted.

Section 14.06.Conversion Rate.Each $1,000 principal amount of the Debentures shall be convertible into 60.6061 fully paid and non-assessable shares of Common Stock attached asExhibit A hereto, subject to adjustment as provided in this ARTICLE 14 (the “Conversion Rate”).

Section 14.07.Adjustment Of Conversion Rate.The Conversion Rate shall be adjusted from time to time (without duplication) by the Company as follows:

(a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of shareholders entitled to receive such dividend or other distribution by a fraction,

(i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for the determination of shareholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 14.07(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall issue rights, options or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for determination of shareholders entitled to receive such rights, options or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of shareholders entitled to receive such rights, options or warrants by a fraction,

(i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of shareholders entitled to receive such rights, options or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase; and

(ii) the denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of shareholders entitled to receive such rights, options or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at a price equal to the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution.

Such adjustment shall be successively made whenever any such rights, options or warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of shareholders entitled to receive such rights, options or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of shareholders entitled to receive such rights, options or warrants had not been fixed. In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at a price less than the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

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

(d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company or evidences of its indebtedness, property or assets (including rights, options, warrants and other securities, but excluding any rights, options or warrants referred to in Section 14.07(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 14.07(a)) (any of the foregoing hereinafter in this Section 14.07(d) called the “Distributed Property”), then, in each such case (unless the Company elects to reserve such Distributed Property for distribution to the Debentureholders upon the conversion of the Debentures so that any such Debentureholder converting Debentures will receive upon such conversion, in addition to the shares of Common Stock to which such Debentureholder is entitled, the amount and kind of such Distributed

Property that such Debentureholder would have received if such Debentureholder had converted its Debentures into Common Stock immediately prior to the Record Date for such distribution of the Distributed Property) the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction,

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

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

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date;providedthat if the then Fair Market Value (as so determined) of the portion of the Distributed Property so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Debentureholder shall have the right to receive on the date of such dividend or distribution the amount of Distributed Property such Debentureholder would have received had such Debentureholder converted each Debenture on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 14.07(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price on the applicable Record Date.

Notwithstanding the foregoing, if the Distributed Property distributed by the Company to all holders of its Common Stock consists of capital stock of, or similar equity interests in, a Subsidiary or other business unit of the Company (unless such capital stock or similar equity interests are distributed to the Debentureholders in such distribution as if such holders had converted their Debentures into shares of Common Stock), the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction,

(i) the numerator of which shall be the sum of (A) the average of the Closing Sale Prices of the Common Stock for the ten (10) consecutive Trading Days commencing on and including the fifth Trading Day after the date on which “ex-dividend trading” commences for such dividend or distribution on the New York Stock Exchange, the Nasdaq Global Market or such other national or regional exchange or market on which such securities are then listed or quoted (the “Ex-Dividend Date”) plus (B) the average Closing Sales Prices of the securities distributed in respect of each share of Common Stock for the ten (10) consecutive Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date; and

(ii) the denominator of which shall be the average of the Closing Sale Prices of the Common Stock for the ten (10) consecutive Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date,

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date;providedthat the Company may in lieu of the foregoing adjustment make adequate provision so that each Debentureholder shall have the right to receive on the date of such distribution the amount of Distributed Property such Debentureholder would have received had such Debentureholder converted each Debenture on the Record Date with respect to such distribution; andprovided furtherthat if (x) the average of the Closing Sale Prices of the Common Stock for the ten (10) consecutive Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date minus (y) the average of the Closing Sale Prices of the securities distributed in respect of each share Common Stock for the ten (10) consecutive Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date is less than $1.00, then the adjustment provided by for by this paragraph shall not be made and in lieu thereof the provisions of the first paragraph of this Section 14.07(d) shall apply to such distribution. In any case in which this paragraph is applicable, Section 14.07(a), Section 14.07(b) and the first paragraph of this Section 14.07(d) shall not be applicable.

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.07 (and no adjustment to the Conversion Rate under this Section 14.07 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.07(d). If any such right or warrant, including any such existing rights, options or warrants distributed prior to the date

of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.07 was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

No adjustment of the Conversion Rate shall be made pursuant to this Section 14.07(d) in respect of rights, options or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights, options or warrants are actually distributed, or reserved by the Company for distribution, to holders of Debentures upon conversion by such holders of Debentures into Common Stock.

For purposes of this Section 14.07(d) and Section 14.07(a) and Section 14.07(b), any dividend or distribution to which this Section 14.07(d) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights, options or warrants (and any Conversion Rate adjustment required by this Section 14.07(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights, options or warrants (and any further Conversion Rate adjustment required by Section 14.07(a) and Section 14.07(b) with respect to such dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of shareholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of shareholders entitled to receive such rights, options or warrants” and “the date fixed for such determination” within the meaning of Section 14.07(a) and Section 14.07(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for the determination of shareholders entitled to receive such dividend or other distribution” or “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 14.07(a).

The reclassification of the Common Stock into securities including securities other than Common Stock (other than any reclassification upon an event to which Section 14.08 applies) shall be deemed to involve (a) a distribution of such securities other than the Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be the “Record Date” within the meaning of this Section 14.07(d)), and (b) 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 Section 14.07(c)).

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

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

(ii) the denominator of which shall be the Current Market Price on such Record Date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock,

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

(f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to shareholders of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Sale Price per share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

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

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

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

(g) In the event a Partnership Company shall issue rights (“IPO Rights”) in a Rights IPO, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the IPO Rights Adjustment Date by a fraction:

(i) the numerator of which will be the sum of (x) the average of the Closing Sale Prices of the Common Stock for the last ten (10) Trading Days that the IPO Rights were publicly traded,plus(y) the quotient of (A) the average closing price of the IPO Rights on the last ten (10) Trading Days that the IPO Rights were publicly traded,divided by(B) the number of shares of Common Stock that are required, under the terms of the IPO Rights, to allow a holder of Common Stock to receive one IPO Right; and

(ii) the denominator of which will be the average of the Closing Sale Prices of the Common Stock for the last ten (10) Trading Days that the IPO Rights were publicly traded,

such adjustment to become effective immediately after the close of business on the date the Rights IPO closed (the “IPO Rights Adjustment Date”). Such adjustment shall be successively made upon each Rights IPO, if any.

(h) In the event a Partnership Company shall undertake, as part of the initial public offering of its common stock pursuant to a registration statement filed under the Securities Act, a Directed Share Subscription Program, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Subscription Rights Adjustment Date by a fraction:

(i) the numerator of which will be the sum of (x) the average of the Closing Sale Prices of the Common Stock for the first four (4) Trading Days on which the common stock of the Partnership Company that is undertaking the Directed Share Subscription Program was publicly traded,plus(y) (A) the difference (if any, and in each case only where (I) is a higher number than (II)) between (I) the average closing price of the common stock of that Partnership Company on the first four (4) Trading Days its common stock is publicly traded, and (II) the initial public offering price of its common stock, divided by (B) the number of shares of Common Stock required to subscribe for one share of common stock of that Partnership Company, and

(ii) the denominator of which will be the average of the Closing Sale Prices of the Common Stock for the first four (4) Trading Days on which the common stock of the Partnership Company that is undertaking the Directed Share Subscription Program was publicly traded,

such adjustment to become effective immediately after the close of business on the last Trading Day of the four Trading Day period described above (the “Subscription Rights Adjustment Date”). Such adjustment shall be successively made upon each initial public offering that includes a Directed Share Subscription Program, if any. If such directed share subscription rights described in this Section 14.07(h) has been declared but not so issued, the Conversion Rate will again be adjusted to be the Conversion Rate that would be in effect if such issuance of directed share subscription rights had not been declared.

(i) The Conversion Rate will be adjusted in connection with a Fundamental Change as follows:

(i) If a Fundamental Change occurs and a Debentureholder elects to convert its Debentures in connection with such Fundamental Change, the Conversion Rate shall, under certain circumstances, be increased with respect to the Debentures so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”) as described below. A conversion of Debentures shall be deemed for these purposes to be “in connection with” such Fundamental Change if the notice of conversion of the Debentures is received by the Conversion Agent from, and including, the Business Day immediately prior to the related Designated Event Repurchase Date, or, in the case of a Fundamental Change that does not also constitute a Designated Event, the date that is thirty-five (35) Business Days following the Effective Date of such Fundamental Change. The Company shall notify the holders of the Debentures and the Trustee of the Effective Date of such Fundamental Change and issue a press release announcing the Effective Date no later than five Business Days after such Effective Date.

(ii) The number of Additional Shares by which the Conversion Rate will be increased shall be determined by reference to the table attached asExhibit Bhereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share of Common Stock in the Fundamental Change. If the holders of Common Stock receive only cash in a Fundamental Change described in clause (i) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Closing Sale Prices of the Common Stock over the five successive Trading Days ending on, and including, the Trading Day immediately preceding the Effective Date of the Fundamental Change.

(iii) The Stock Prices set forth in the column headings of the table inExhibit B hereto shall be adjusted as of any date on which the Conversion Rate of the Debentures is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the stock price adjustment and the denominator of which is the Conversion Rate as so adjusted.

(iv) If the exact Stock Prices and Effective Dates are not set forth in the table inExhibit B, then:

(1) If the Stock Price is between two adjacent Stock Price amounts in the table or the Effective Date is between two adjacent Effective Dates in the table, then the number of Additional Shares by which the Conversion Rate will be increased will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower stock price amounts and the two dates, as applicable, based on a 365-day year.

(2) If the Stock Price is greater than $60.00 per share (subject to adjustment in the same manner as the Stock Prices as set forth in the column headings of the table inExhibit Bhereto), then no Additional Shares will be added to the Conversion Rate.

(3) If the Stock Price is less than $12.00 per share (subject to adjustment in the same manner as the Stock Prices as set forth in the column headings of the table inExhibit Bhereto), then no Additional Shares will be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate exceed $12.00 per $1,000 principal amount of Debentures, subject to adjustments in the same manner, and at the same time, as the Conversion Rate as set forth in Section 4.04.

(v) If a Debentureholder elects to convert its Debentures prior to the Effective Date of any Fundamental Change, such Debentureholder shall not be entitled to an increased Conversion Rate in connection with such conversion.

(j) For purposes of this Section 14.07, the following terms shall have the meaning indicated:

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

If another issuance, distribution, subdivision or combination to which Section 14.07 applies occurs during the period applicable for calculating “Current Market Price” pursuant to the definition in the preceding paragraph, “Current Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period.

(ii) “Fair Market Value” shall mean the amount that a willing buyer would pay a willing seller in an arm’s-length transaction.

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

(iv) “Trading Day” shall mean a day during which trading in securities generally occurs on the New York Stock Exchange or, if the Common Stock is not listed on the New York Stock Exchange, on the principal other national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not listed on a national or regional securities exchange on the principal other market on which the Common Stock is then traded.

(k) The Company may make such increases in the Conversion Rate, in addition to those required by Section 14.07(a), (b), (c), (d), (e), (f), (g), (h) or (h) as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

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

(l) All calculations under this ARTICLE 14 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities. To the extent the Debentures become convertible into cash, assets, property or securities (other than capital stock of the Company or any other Person), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on any cash into which the Debentures are convertible.

(m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and the Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail, or cause the Trustee to mail, such notice of such adjustment of the Conversion Rate to the each Debentureholder at his last address appearing on the Debenture Register provided for in Section 2.05, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(n) In any case in which this Section 14.07 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of shareholders entitled to receive a dividend or distribution pursuant to Section 14.07(a), (3) a date fixed for the determination of shareholders entitled to receive rights, options or warrants pursuant to Section 14.07(b), (4) the Expiration Time for any tender or exchange offer pursuant to Section 14.07(f), (5) in the case of Section 14.07(h), the close of business on the last Trading Day of the four Trading Day period described in Section 14.07(h) or (6) in the case of Section 14.07(h), the close of business on the last Trading Day of the five Trading Day period described in Section 14.07(h) (each a “Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to any Debentureholder converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such Debentureholder any amount in cash in lieu of any fraction pursuant to Section 14.02. For purposes of this Section 14.07(n), the term “Adjustment Event” shall mean:

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

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

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

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

(v) in any case referred to in clause (5) hereof, the date on which the directed share subscription rights described in Section 14.07(h) are issued, and

(vi) in any case referred to in clause (6) hereof, the Effective Date of the applicable Fundamental Change.

(o) For purposes of this Section 14.07, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

Section 14.08.Effect Of Reclassification, Consolidation, Merger or Sale.

(a) If any of the following events occur, namely (a) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 14.07(c) applies), (b) any consolidation, merger or binding share exchange of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (c) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that each Debenture shall be changed into a right to convert each $1,000 principal amount

of Debentures into the kind and amount of shares of stock, other securities or other property or assets (including cash) (the “Reference Property”) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have received on account of such transaction, assuming such holder is entitled to participate in such transaction on the basis of holding such shares;provided, however,that, at and after the effective time of such transaction, upon any conversion of a Debenture, (A) any portion of the Conversion Consideration due upon such conversion that would have been payable in cash pursuant to Section 14.04 had such transaction not occurred shall continue to be payable in cash, (B) any portion of the Conversion Consideration due upon such conversion that would have been payable in shares of Common Stock pursuant to Section 14.04 had such transaction not occurred shall instead be payable in such Reference Property and (C) the VWAP per share of Common Stock shall, for these purposes, be calculated based on the value of a unit of Reference Property that a holder of one (1) share of Common Stock would have been entitled to receive in such transaction.

(b) If the Reference Property in respect of such transaction consists solely of cash and the effective time of the such transaction occurs on or before the third Business Day after the last Trading Day in any Observation Period applicable to the conversion of any Security (in the event Physical Settlement does not apply to such conversion) or on or before the third Business Day after the Conversion Date of such conversion (in the event Physical Settlement applies to such conversion), then (x) the Conversion Consideration due upon such conversion shall consist of cash in an amount, per $1,000 principal amount of such Security, equal to the product of (i) the amount of cash paid per share of Common Stock pursuant to such transaction and (ii) the Conversion Rate on the Conversion Date for such conversion; and (y) such consideration shall be paid no later than the third (3rd) Business Day after the later of such Conversion Date and such effective date.

(c) If such transaction causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then the Reference Property into which the Debentures shall be convertible shall be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock, subject to the Company’s (or its successor’s) right, pursuant to Section 14.04, to deliver, in lieu of Reference Property, cash or a combination of cash and Reference Property.

(d) Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this ARTICLE 14.

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

(f) The provisions of this Section 14.08 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances.

(g) If this Section 14.08 applies to any event or occurrence, then Section 14.07 shall not apply.

Section 14.09.Taxes On Shares Issued.The issue of stock certificates on conversions of Debentures shall be made without charge to the converting Debentureholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any such tax that may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of any Debentureholder converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 14.10.Reservation of Shares, Shares to Be Fully Paid;Compliance With Governmental Requirements;Listing of Common Stock.The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Debentures from time to time as such Debentures are presented for conversion.

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

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

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

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

Section 14.11.Responsibility Of Trustee.The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Debentureholder to determine the Conversion Rate or whether any facts exist that may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Debenture; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Debenture for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this ARTICLE 14. Without limiting the generality of the foregoing, neither the Trustee nor the Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.08 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Debentureholders upon the conversion of their Debentures after any event referred to in such Section 14.08 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 14.12.Notice To Holders Prior To Certain Actions.In case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 14.07; or

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

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

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

(e) a Partnership Company issues IPO Rights in a Rights IPO; or

(f) a Partnership Company undertakes, as part of the initial public offering of its common stock pursuant to a registration statement filed under the Securities Act, a Directed Share Subscription Program;

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

Section 14.13.Issuer Determination Final.Any determination that the Company or Board of Directors of the Company must make pursuant to this ARTICLE 14 shall, absent manifest error, be conclusive.

FORM OF REVERSE OF DEBENTURE

SAFEGUARD SCIENTIFICS, INC.

10.125% CONVERTIBLE SENIOR DEBENTURE DUE MARCH 15, 2014

This Debenture is one of a duly authorized issue of Debentures of the Company, designated as its 10.125% Convertible Senior Debentures Due March 15, 2014 (the “Debentures”), limited in aggregate principal amount to $46,936,000, issued and to be issued under and pursuant to an Indenture dated as of March 26, 2010 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures.

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

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of at least a majority in aggregate principal amount of the Debentures at the time Outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Debentures;providedthat no such supplemental indenture shall (i) extend the fixed maturity of any Debenture, reduce the rate or extend the time of payment of Interest thereon, reduce the principal amount thereof, reduce any amount payable upon repurchase thereof, impair the right of any Debentureholder to institute suit for the payment thereof, make the principal thereof or Interest thereon payable in any coin or currency other than that provided in the Debentures, change the obligation of the Company to repurchase any Debenture upon the happening of a Designated Event in a manner adverse to the holders of the Debentures, impair the right to convert the Debentures into Common Stock subject to the terms set forth in the Indenture, including Article 13 thereof, reduce the number of shares of Common Stock or amount of other property receivable upon conversion of the Debentures, modify any of the provisions of Section 5.07 or Section 9.02 thereof, except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Debenture so affected, change any obligation of the Company to maintain an office or agency in the places and for the purposes set forth in Section 3.02 thereof, or reduce the quorum or voting requirements set forth in Article 8 or (ii) reduce the aforesaid percentage of Debentures, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all Debentures then Outstanding.

A-7

Subject to the provisions of the Indenture, the holders of a majority in aggregate principal amount of the Debentures at the time Outstanding may on behalf of the holders of all of the Debentures waive any past default or Event of Default under the Indenture and its consequences except (A) a default in the payment of Interest, or the principal of, any of the Debentures, (B) a failure by the Company to convert any Debentures into Common Stock of the Company, (C) a default in respect of a covenant or provisions of the Indenture that under the terms of the Indenture cannot be modified or amended without the consent of the holders of each or all Debentures then Outstanding or affected thereby, or (D) a default in the payment of the repurchase price paid pursuant to ARTICLE 3 of the Indenture. Any such consent or waiver by the Holder of this Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future holders and owners of this Debenture and any Debentures that may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Debenture or such other Debentures.

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

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

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

If a Designated Event occurs at any time prior to maturity of the Debentures, the Debentures may be repurchased at the option of the holders of the Debentures on a Designated Event Repurchase Date, not less than 20 nor more than 35 Business Days after notice thereof, at the option of the holder of this Debenture at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid Interest to (but excluding) the repurchase date;providedthat if such Designated Event Repurchase Date falls after a Record Date and on or prior the corresponding Interest Payment Date, the Interest payable on such Interest Payment Date shall be paid to the holder of record of this Debenture on the corresponding Record Date. The Debentures will be repurchased in multiples of $1,000 principal amount. The Company shall mail, or cause the Trustee to mail, to all holders of record of the Debentures a notice of the occurrence of a Designated Event and of the repurchase right arising as a result thereof on or before the 20th day after the occurrence of such Designated Event. For a Debenture to be so repurchased at the option of the holder, the Company must receive at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, such Debenture with the form entitled “Option to Elect Repurchase Upon a Designated Event” on the reverse thereof duly completed, together with such Debenture, duly endorsed for transfer, on or before the Designated Event Expiration Time.

A-8

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

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

In compliance with the provisions of the Indenture, prior to the final maturity date of the Debentures, the Holder hereof has the right, at its option, to convert each $1,000 principal amount of the Debentures into 60.6061 shares of the Company’s Common Stock (a conversion price of $16.50 per share), as such shares shall be constituted at the date of conversion and subject to adjustment from time to time as provided in the Indenture, upon surrender of this Debenture with the form entitled “Conversion Notice” on the reverse thereof duly completed, to the Company at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, or at the option of such Holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Debenture, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized attorney. The Company will notify the Holder thereof of any event triggering the right to convert the Debentures as specified above in accordance with the Indenture.

No adjustment in respect of Interest on any Debenture converted or dividends on any shares issued upon conversion of such Debenture will be made upon any conversion except as set forth in the next sentence. If this Debenture (or portion hereof) is surrendered for conversion during the period from the close of business on any Record Date for the payment of Interest to the close of business on the Business Day preceding the following Interest Payment Date, this Debenture (or portion hereof being converted) must be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the Interest otherwise payable on such Interest Payment Date on the principal amount being converted;providedthat no such payment shall be required (1) if the Company has specified a repurchase date that is after a Record Date and prior to the next Interest Payment Date, (2) if the Company has specified a Designated Event Repurchase Date that is during such period or (3) to the extent of any overdue Interest, if any overdue Interest exists at the time of conversion with respect to such Debenture.

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

A-9

A Debenture in respect of which a holder is exercising its right to require repurchase upon a Designated Event may be converted only if such holder withdraws its election to exercise either such right in accordance with the terms of the Indenture.

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

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

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