The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage, provided such notations, legends or endorsements are in form reasonably acceptable to the Company. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. Securities offered and sold in reliance on Rule 144A shall be issued initially in the form of one or more Global Securities, in registered form, substantially in the form set forth in EXHIBIT A (the "GLOBAL SECURITY"), deposited with the Trustee, as custodian for the Depositary, and registered in the name of the Depositary or a nominee thereof, duly executed by the Company and authenticated by the Trustee as hereinafter provided and bearing the legends set forth in EXHIBITS B-1 and B-2. The aggregate principal amount of the Global Security may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, as hereinafter provided; provided, that in no event shall the aggregate principal amount of the Global Security or Securities exceed $50,000,000 (or $60,000,000 if the Initial Purchasers elect to purchase all of the Additional Securities pursuant to the Option). Securities issued in exchange for interests in a Global Security pursuant to Section 2.15 may be issued in the form of permanent certificated Securities in registered form in substantially the form set forth in EXHIBIT A (the "PHYSICAL SECURITIES") and, if applicable, bearing any legends required by Section 2.17. 2.02 EXECUTION AND AUTHENTICATION. One duly authorized Officer shall sign the Securities for the Company by manual or facsimile signature. A Security's validity shall not be affected by the failure of an Officer whose signature is on such Security to hold, at the time the Security is authenticated, the same office at the Company. A Security shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. Upon a written order of the Company signed by one Officer of the Company, the Trustee shall authenticate Securities for original issue in the aggregate principal amount of $50,000,000 and such additional principal amount, if any, as shall be determined pursuant to the next sentence of this Section 2.02.

Such Officer's Certificate must be received by the Trustee not later than the proposed date for delivering of such Additional Securities. The aggregate principal amount of Securities outstanding at any time may not exceed $50,000,000 except as provided in this Section 2.02. Upon a written order of the Company signed by one Officer of the Company, the Trustee shall authenticate Securities not bearing the Private Placement Legend to be issued to the transferee when sold pursuant to an effective registration statement under the Securities Act as set forth in Section 2.16(B). The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such authenticating agent. An authenticating agent has the same rights as a Security Agent to deal with the Company and its Affiliates. If a written order of the Company pursuant to this Section 2.02 has been, or simultaneously is, delivered, any instructions by the Company to the Trustee with respect to endorsement, delivery or redelivery of a Security issued in global form shall be in writing but need not comply with Section 11.04 hereof and need not be accompanied by an Opinion of Counsel.

If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company initially appoints the Trustee as Paying Agent, Registrar and Conversion Agent and designates the Corporate Trust Office of the Trustee for the purposes enumerated in the first paragraph of this Section 2.03. 2.04 PAYING AGENT TO HOLD MONEY IN TRUST. Each Paying Agent shall hold in trust for the benefit of the Securityholders or the Trustee all moneys and, if applicable, other property held by the Paying Agent for the payment of the Securities, and shall notify the Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money and, if applicable, other property held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money and, if applicable, other property held by it to the Trustee and account for any funds so paid by it. Upon payment over to the Trustee, the Paying Agent shall have no further liability for such money and, if applicable, other property. If the Company acts as Paying Agent, it shall segregate and hold as a separate trust fund all money and, if applicable, other property held by it as Paying Agent. 2.05 SECURITYHOLDER LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall (i) furnish to the Trustee on or before each interest payment date, a list of the names and addresses of Securityholders appearing on the security register of the Registrar; and (ii) furnish, within thirty (30) days after the receipt by the Company of such request, to the Trustee, at such other times as the Trustee may request in writing, a list of similar form and content, which list shall be as of a date not more than fifteen (15) days before the date such list is furnished. 2.06 TRANSFER AND EXCHANGE. Subject to Sections 2.15 and 2.16 hereof, where Securities are presented to the Registrar with a request to register their transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer and exchanges, the Trustee shall authenticate Securities at the Registrar's request or upon the Trustee's receipt of a Company Order therefor. The Company or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security (i) for a period of fifteen (15) days before selecting, pursuant to Section 3.03, Securities to be redeemed or (ii) during a period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of the Securities selected for Redemption under Section 3.04 and ending at the close of business on the day of such mailing or (iii) that has been selected for Redemption or for which a Purchase Notice has been delivered, and not withdrawn, in accordance with this -10- Indenture, except the unredeemed or unrepurchased portion of Securities being redeemed or repurchased in part. No service charge shall be made for any transfer, exchange or conversion of Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Securities, other than exchanges pursuant to Sections 2.10, 9.05 or 10.02, or Article III, not involving any transfer. 2.07 REPLACEMENT SECURITIES. If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, issue and the Trustee, upon receipt of a Company Order therefor, shall authenticate a replacement Security upon surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Security, the Trustee or the Company may require the Holder of such Security to deliver, prior to the issuance and authentication of a replacement Security, an indemnity bond that is reasonably satisfactory to the Trustee and the Company to indemnify and hold harmless the Company, the Trustee and any Security Agent from any loss which any of them may suffer if such Security is replaced. The Company and the Trustee may charge such Holder for their expenses (including taxes or governmental charges incurred) in replacing a Security. In case any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable (whether at maturity, upon Redemption, on an Option Purchase Date with respect to a Purchase at Holder's Option or on a Fundamental Change Repurchase Date with respect to a Repurchase Upon Fundamental Change), the Company in its discretion may, instead of issuing a new Security, pay such Security when due. Every replacement Security is an additional obligation of the Company only as provided in Section 2.08. 2.08 OUTSTANDING SECURITIES. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those converted, those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Except to the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the Security. If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or a court holds, that the replaced Security is held by a bona fide purchaser. If the Paying Agent (other than the Company) holds on an Option Purchase Date, Redemption Date, Fundamental Change Repurchase Date or Maturity Date, money sufficient to -11- pay the aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, as the case may be, with respect to all Securities to be redeemed, purchased or paid upon Purchase at Holder's Option, Redemption, Repurchase Upon Fundamental Change or maturity, as the case may be, in each case plus, if applicable, accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option, Redemption, Repurchase Upon Fundamental Change or maturity, then (unless there shall be a Default in the payment of such aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, or of such accrued and unpaid interest) on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, as the case may be, plus, if applicable, such accrued and unpaid interest, in accordance with this Indenture. If a Security is converted in accordance with Article X, then, from and after the time of such conversion on the Conversion Date, such Security shall cease to be outstanding, and interest, if any, shall cease to accrue on such Security. 2.09 SECURITIES HELD BY THE COMPANY OR AN AFFILIATE. In determining whether the Holders of the required aggregate principal amount of Securities have concurred in any request, demand, direction, waiver or consent, Securities owned by the Company or any of its Subsidiaries or Affiliates shall be considered as though not outstanding, except that, for the purposes of determining whether a Responsible Officer of the Trustee shall be protected in relying on any such request, demand, direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee, the pledgee's right so to concur with respect to such Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company or an affiliate of any such other obligor. In the event of a dispute as to whether the pledgee has established the foregoing, the Trustee may rely on the advice of counsel or on an Officer's Certificate. 2.10 TEMPORARY SECURITIES. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall, upon its receipt of a Company Order therefor, authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance with the terms of this Indenture. -12- 2.11 CANCELLATION. The Company at any time may deliver Securities (which the Company may have duly acquired in any manner whatsoever) to the Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Securities surrendered to them for Redemption, Purchase at Holder's Option, Repurchase Upon Fundamental Change, transfer, exchange, payment or conversion. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange, payment (whether at maturity, upon Redemption, upon a Purchase at Holder's Option, or upon a Repurchase Upon Fundamental Change), conversion or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Securityholder has converted pursuant to Article X. All cancelled Securities held by the Trustee shall be destroyed, and certification of their destruction shall be delivered by the Trustee to the Company unless the Company shall, by a Company Order, direct that cancelled Securities be returned to it. 2.12 DEFAULTED INTEREST. If and to the extent the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities. The Company may pay the defaulted interest (plus interest on such defaulted interest) to the persons who are Securityholders on a subsequent special record date. The Company shall fix such record date and payment date. At least fifteen (15) calendar days before such record date, the Company shall mail to Securityholders a notice that states the record date, payment date and amount of interest to be paid, and the Company shall cause any such defaulted interest (plus interest on such defaulted interest) to be paid to Holders of record of each applicable Security at 5:00 p.m., New York City time, on such record date. Upon such due payment in full, such defaulted interest (plus interest on such defaulted interest) shall no longer be payable pursuant to this Section 2.12. 2.13 CUSIP NUMBERS. The Company in issuing the Securities may use one or more "CUSIP" numbers, and, if so, the Trustee shall use the CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities; provided further, that reliance may be placed only on the other identification numbers printed on the Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers. 2.14 DEPOSIT OF MONEYS AND PROPERTY. Prior to 11:00 A.M., New York City time, on each interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, the Company shall have deposited with a Paying Agent (or, if the Company is acting as its own -13- Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, and, if applicable as provided herein, such other consideration, sufficient to make cash payments and deliver such other consideration, if any, due on such interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, as the case may be. If, pursuant to Section 4.01 hereof and paragraph 3 of the Securities, payment shall be made to Holders by check, then such deposit shall be made in such manner as will permit such remittance to be made by check drawn upon a bank in the city in which the Paying Agent's principal office, or the Corporate Trust Office of the Trustee, shall be located. 2.15 BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITIES. (A) The Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of the Depositary, (ii) be delivered to the Trustee as custodian for the Depositary and (iii) bear legends as set forth in Section 2.17. Members of, or participants in, the Depositary ("PARTICIPANTS") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security 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 impair, as between the Depositary and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security. (B) Transfers of Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. In addition, Physical Securities shall be transferred to all beneficial owners, as identified by the Depositary, in exchange for their beneficial interests in Global Securities only if (i) the Depositary notifies the Company that the Depositary is unwilling or unable to continue as depositary for any Global Security (or the Depositary ceases to be a "clearing agency" registered under Section 17A of the Exchange Act) and a successor Depositary is not appointed by the Company within ninety (90) days of such notice or cessation or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the Depositary to issue Physical Securities. (C) In connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(B), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations. -14- (D) Any Physical Security constituting a Restricted Security delivered in exchange for an interest in a Global Security pursuant to Section 2.15(B) shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend. (E) The Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities. 2.16 SPECIAL TRANSFER PROVISIONS. (A) RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL SECURITIES. Notwithstanding any other provisions of this Indenture, but except as provided in Section 2.15(B), a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (B) PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or replacement of Securities not bearing the Private Placement Legend, the Registrar or co-Registrar shall deliver Securities that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Securities bearing the Private Placement Legend, the Registrar or co-Registrar shall deliver only Securities that bear the Private Placement Legend unless (i) the requested transfer is after the Resale Restriction Termination Date, (ii) there is delivered to the Trustee and the Company an Opinion of Counsel (upon which Opinion of Counsel the Trustee may conclusively rely) reasonably satisfactory to the Company and addressed to the Company to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act or (iii) such Security has been sold pursuant to an effective registration statement under the Securities Act and the Holder selling such Securities has delivered to the Registrar or co-Registrar a notice in the form of EXHIBIT C hereto. Upon the effectiveness, under the Securities Act, of the "SHELF REGISTRATION STATEMENT" (as defined in the Registration Rights Agreement), the Company shall deliver to the Trustee a notice of effectiveness, a Global Security or Global Securities, which do not bear the Private Placement Legend, an authentication order in accordance with Section 2.02 and an Opinion of Counsel in the form of EXHIBIT D hereto, and, if required by the Depositary, the Company shall deliver to the Depositary a letter of representations in a form reasonably acceptable to the Depositary. Upon the effectiveness of any post-effective amendment to the "Shelf Registration Statement" (as defined in the Registration Rights Agreement) and upon the effectiveness, under the Securities Act, of any "Subsequent Shelf Registration Statement" (as defined in the Registration Rights Agreement), the Company shall deliver to the Trustee a notice of effectiveness and an Opinion of Counsel in the form of EXHIBIT D hereto. Upon any sale, pursuant to a Shelf Registration Statement, of a beneficial interest in a Global Security that theretofore constituted a Restricted Security and delivery of appropriate evidence thereof to the Trustee, and upon any sale or transfer of a beneficial interest in connection with which the Private Placement Legend will be removed in accordance with this Indenture, the Trustee shall increase the principal amount of the Global Security that does not constitute a Restricted Security by the principal amount of such sale or transfer and likewise reduce the principal amount of the Global Security that does constitute a Restricted Security. -15- (C) GENERAL. By its acceptance of any Security bearing the Private Placement Legend, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Security only as provided in this Indenture and as permitted by applicable law. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this Section 2.16. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time during normal hours of operation of the Registrar upon the giving of reasonable written notice to the Registrar. (D) TRANSFERS OF SECURITIES HELD BY AFFILIATES. Any certificate (i) evidencing a Security that has been transferred to an Affiliate within two (2) years after the Issue Date, as evidenced by a notation on the assignment form for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Security that has been acquired from an Affiliate (other than by an Affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until two (2) years after the last date on which the Company or any Affiliate was an owner of such Security (or such longer period of time as may be required under the Securities Act or applicable state securities laws), in each case, bear the Private Placement Legend, unless otherwise agreed by the Company (with written notice thereof to the Trustee). 2.17 RESTRICTIVE LEGENDS. Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the "PRIVATE PLACEMENT LEGEND") as set forth in EXHIBIT B-1 on the face thereof until after the second anniversary of the later of (i) the Issue Date and (ii) the last date on which the Company or any Affiliate was the owner of such Security (or any predecessor security) (or such shorter period of time as permitted by Rule 144(k) promulgated under under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as set forth in an Opinion of Counsel, unless otherwise agreed between the Company and the Holder thereof) (such date, the "RESALE RESTRICTION TERMINATION DATE"). Each Global Security shall also bear the legend as set forth in EXHIBIT B-2. 2.18 RANKING. The indebtedness of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture from time to time constitutes and will constitute a senior unsecured obligation of the Company, ranking equally with other existing and future senior unsecured indebtedness of the Company and ranking senior to any existing or future indebtedness of the Company that, by its terms, is made subordinate to senior indebtedness of the Company. -16- III. REDEMPTION AND REPURCHASE 3.01 RIGHT OF REDEMPTION. (A) Redemption of the Securities, as permitted by any provision of this Indenture, shall be made: (i) with respect to a repurchase at the Company's option, in accordance with paragraphs 6 and 7 of the Securities (a "REDEMPTION"), (ii) with respect to a repurchase at the Holder's option, in accordance with paragraph 8 of the Securities (a "PURCHASE AT HOLDER'S OPTION") and (iii) with respect to any repurchase upon a Fundamental Change, in accordance with paragraph 9 of the Securities (a "REPURCHASE UPON FUNDAMENTAL CHANGE"), in each case in accordance with the applicable provisions of this Article III. (B) The Company will comply with all federal and state securities laws, and any applicable laws of any foreign jurisdiction, in connection with any offer to sell or solicitations of offers to buy Securities pursuant to this Article III. (C) The Company shall not have the right to redeem any Securities prior to February 1, 2012. The Company shall have the right, at the Company's option, at any time, and from time to time, on a Redemption Date on or after February 1, 2012, to redeem all or any part of the Securities at a price payable in cash equal to the Redemption Price plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date. (D) Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount. 3.02 NOTICES TO TRUSTEE. If the Company elects to redeem Securities pursuant to paragraph 6 of the Securities, it shall notify the Trustee in writing of the Redemption Date, the applicable provision of this Indenture pursuant to which the Redemption is to be made and the aggregate principal amount of Securities to be redeemed, which notice shall be provided to the Trustee by the Company at least fifteen (15) days prior to the mailing, in accordance with Section 3.04, of the notice of Redemption (unless a shorter notice period shall be satisfactory to the Trustee). 3.03 SELECTION OF SECURITIES TO BE REDEEMED. If the Company has elected to redeem less than all the Securities pursuant to paragraph 6 of the Securities, the Trustee shall, within five (5) Business Days after receiving the notice specified in Section 3.02, select the Securities to be redeemed by lot, on a pro rata basis or in accordance with any other method the Trustee considers fair and appropriate. The Trustee shall make such selection from Securities then outstanding and not already to be redeemed by virtue -17- of having been previously called for Redemption. The Trustee may select for Redemption portions of the principal amount of Securities that have denominations larger than $1,000 principal amount. Securities and portions of them the Trustee selects for Redemption shall be in amounts of $1,000 principal amount or integral multiples of $1,000 principal amount. The Trustee shall promptly notify the Company in writing of the Securities selected for Redemption and the principal amount thereof to be redeemed. The Registrar need not register the transfer of or exchange any Securities that have been selected for Redemption, except the unredeemed portion of the Securities being redeemed in part. The Registrar need not issue, authenticate, register the transfer of or exchange any Security for a period of fifteen (15) days before selecting, pursuant to this Section 3.03, Securities to be redeemed. 3.04 NOTICE OF REDEMPTION. At least thirty (30) days but not more than sixty (60) days before a Redemption Date, the Company shall mail, or cause to be mailed, by first-class mail a notice of Redemption to each Holder whose Securities are to be redeemed, at the address of such Holder appearing in the security register. The notice shall identify the Securities and the aggregate principal amount thereof to be redeemed pursuant to the Redemption and shall state: (i) the Redemption Date; (ii) the Redemption Price plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date; (iii) the Conversion Rate and the Conversion Price; (iv) the names and addresses of the Paying Agent and the Conversion Agent; (v) that the right to convert the Securities called for Redemption will terminate at the close of business on the third (3rd) Business Day immediately preceding the Redemption Date, unless there shall be a Default in the payment of the Redemption Price or accrued and unpaid interest, if any, payable as herein provided upon Redemption; (vi) that Holders who want to convert Securities must satisfy the requirements of Article X; (vii) the paragraph of the Securities pursuant to which the Securities are to be redeemed; (viii) that Securities called for Redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued and unpaid interest, if any, payable as herein provided upon Redemption; -18- (ix) that, unless there shall be a Default in the payment of the Redemption Price or accrued and unpaid interest, if any, payable as herein provided upon Redemption, interest on Securities called for Redemption ceases to accrue on and after the Redemption Date, such Securities will cease to be convertible after the close of business on the third (3rd) Business Day immediately preceding the Redemption Date, and all rights of the Holders of such Securities shall terminate on and after the Redemption Date, other than the right to receive, upon surrender of such Securities and in accordance with this Indenture, the Redemption Price and such accrued and unpaid interest; and (x) the CUSIP number or numbers, as the case may be, of the Securities. The right, pursuant to Article X, to convert Securities called for Redemption shall terminate at the close of business on the third (3rd) Business Day immediately preceding the Redemption Date, unless there shall be a Default in the payment of the Redemption Price or accrued and unpaid interest, if any, payable as herein provided upon Redemption. At the Company's request, upon reasonable prior notice, the Trustee shall mail the notice of Redemption in the Company's name and at the Company's expense; provided, however, that the form and content of such notice shall be prepared by the Company. 3.05 EFFECT OF NOTICE OF REDEMPTION. Once notice of Redemption is mailed, Securities called for Redemption become due and payable on the Redemption Date at the Redemption Price plus accrued and unpaid interest to, but excluding, the Redemption Date, and, on and after such Redemption Date (unless there shall be a Default in the payment of the Redemption Price or such accrued and unpaid interest), such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other than the right to receive, upon surrender of such Securities and in accordance with the next sentence, the Redemption Price and such accrued and unpaid interest. Upon surrender to the Paying Agent of a Security subject to Redemption, such Security shall be paid, to the Holder surrendering such Security, at the Redemption Price plus accrued and unpaid interest to, but excluding, the Redemption Date, unless the Redemption Date is an interest payment date, in which case such accrued and unpaid interest will instead be paid on such interest payment date to the Holder of record of such Security at the close of business on the record date for such interest payment. If any Security shall not be fully and duly paid upon surrender thereof for Redemption, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest from, and including, the Redemption Date at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to a Redemption if there has occurred (prior to, on or after, as the case may be, the mailing of the notice of Redemption specified in Section 3.04) and is continuing an Event of Default (other than a Default in the payment of the Redemption Price or accrued and unpaid -19- interest, if any, payable as herein provided upon Redemption). The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of such an Event of Default. 3.06 DEPOSIT OF REDEMPTION PRICE. Prior to 11:00 A.M., New York City time on the Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on the Redemption Date, sufficient to pay the Redemption Price, plus accrued and unpaid interest to, but excluding, the Redemption Date, of all Securities to be redeemed on that date. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. 3.07 SECURITIES REDEEMED IN PART. Any Security to be submitted for Redemption only in part shall be delivered pursuant to Section 3.05 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing). Upon receipt of such Security together with any such required endorsements or transfer instruments, the Company shall execute, and the Trustee shall, upon its receipt of a Company Order therefor, authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Redemption. If any Security selected for partial Redemption is converted in part, the principal of such Security subject to Redemption shall be reduced by the principal amount of such Security that is converted. 3.08 PURCHASE OF SECURITIES AT OPTION OF THE HOLDER. (A) At the option of the Holder thereof, Securities (or portions thereof that are integral multiples of $1,000 in principal amount) shall be purchased by the Company pursuant to paragraph 8 of the Securities on February 1, 2012, February 1, 2015 and February 1, 2020 (each, an "OPTION PURCHASE DATE"), at a purchase price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities (or such portions thereof) to be so purchased (the "OPTION PURCHASE PRICE"), plus accrued and unpaid interest, if any, to, but excluding, the applicable Option Purchase Date, upon: (i) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice (as defined below), by such Holder, at any time from 9:00 a.m., New York City time, on the date that is twenty (20) Business Days prior to the applicable Option Purchase Date until 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the applicable Option Purchase Date, of a Purchase Notice, in the form set forth in the Securities (or any other form of written notice delivered in -20- good faith and substantially similar thereto), duly completed and signed, with appropriate signature guarantee, stating: (a) the certificate number(s) of the Securities which the Holder will deliver to be purchased, if such Securities are in the form of Physical Securities; (b) the principal amount of Securities to be purchased, which must be $1,000 or an integral multiple thereof; and (c) that such principal amount of Securities are to be purchased as of the applicable Option Purchase Date pursuant to the terms and conditions specified in paragraph 8 of the Securities and in this Indenture; and (ii) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice, at any time after delivery of such Purchase Notice, of such Securities (such Securities to conform in all material respects to the description thereof in the related Option Purchase Notice), together with all necessary endorsements, such delivery being a condition to receipt by the Holder of the Option Purchase Price therefor plus accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option; If such Securities are held in book-entry form through the Depositary, the Purchase Notice shall comply with applicable procedures of the Depositary. Upon such delivery of Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled, upon request, to receive from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery. Notwithstanding anything herein to the contrary, any Holder that has delivered the Purchase Notice contemplated by this Section 3.08(A) to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice shall have the right to withdraw such Purchase Notice by delivery, at any time prior to 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the applicable Option Purchase Date, of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying Agent, which notice shall contain the information specified in Section 3.08(B)(vii). The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof. (B) The Company shall give notice (the "OPTION PURCHASE NOTICE") on a date not less than twenty (20) Business Days prior to each Option Purchase Date to all Holders at their addresses shown in the register of the Registrar and to beneficial owners as required by applicable law. Such notice shall state: -21- (i) the Option Purchase Price plus accrued and unpaid interest, if any, to, but excluding, such Option Purchase Date and the Conversion Rate; (ii) the names and addresses of the Paying Agent and the Conversion Agent; (iii) that Securities with respect to which a Purchase Notice is given by a Holder may be converted pursuant to Article X only if such Purchase Notice has been withdrawn in accordance with this Section 3.08 or if there shall be a Default in the payment of such Option Purchase Price or in accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option; (iv) that Securities must be surrendered (together with any necessary endorsements) to the Paying Agent to collect payment of the Option Purchase Price plus accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option; (v) that the Option Purchase Price, plus accrued and unpaid interest, if any, to, but excluding, such Option Purchase Date, for any Security as to which a Purchase Notice has been given and not withdrawn will be paid as promptly as practicable, but in no event more than three (3) Business Days, following the later of such Option Purchase Date or the time of delivery of the Security as described in clause (iv) above; (vi) the procedures the Holder must follow to exercise rights under this Section 3.08 (including the name and address of the Paying Agent) and a brief description of those rights; (vii) that a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent) or the Paying Agent receives, at any time prior to 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the applicable Option Purchase Date, or such longer period as may be required by law, a letter or telegram, telex or facsimile transmission (receipt of which is confirmed and promptly followed by a letter) setting forth (I) the name of such Holder, (II) a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Option Purchase Date pursuant to a Purchase at Holder's Option, (III) the certificate number of such Securities to be so withdrawn (if such Securities are in the form of Physical Securities), (IV) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and (V) the principal amount, if any, of the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.08, which amount must be $1,000 or an integral multiple thereof; (viii) that, on and after the applicable Option Purchase Date (unless there shall be a Default in the payment of such Option Purchase Price or such accrued and unpaid interest), interest on Securities subject to Purchase at Holder's Option will -22- cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive, upon surrender of such Securities and in accordance with this Section 3.08, the Option Purchase Price and such accrued and unpaid interest; and (ix) the CUSIP number or numbers, as the case may be, of the Securities. At the Company's request, upon reasonable prior notice, the Trustee shall mail such Option Purchase Notice in the Company's name and at the Company's expense; provided, however, that the form and content of such Option Purchase Notice shall be prepared by the Company. No failure of the Company to give an Option Purchase Notice shall limit any Holder's right pursuant hereto to exercise its rights to require the Company to purchase such Holder's Securities pursuant to a Purchase at Holder's Option. (C) Subject to the provisions of this Section 3.08, the Company shall pay, or cause to be paid, the Option Purchase Price, plus accrued and unpaid interest, if any, to, but excluding, the applicable Option Purchase Date, with respect to each Security subject to Purchase at Holder's Option to the Holder of record thereof as promptly as practicable, but in no event more than three (3) Business Days, following the later of the applicable Option Purchase Date and the time such Security (together with all necessary endorsements) is surrendered to the Paying Agent. (D) Prior to 11:00 A.M., New York City time on the applicable Option Purchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on the applicable Option Purchase Date, sufficient to pay the Option Purchase Price, plus accrued and unpaid interest, if any, to, but excluding, such Option Purchase Date, of all of the Securities that are to be purchased by the Company on such Option Purchase Date pursuant to a Purchase at Holder's Option. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. (E) Once the Purchase Notice has been duly delivered in accordance with this Section 3.08, the Securities to be purchased pursuant to the Purchase at Holder's Option shall, on the applicable Option Purchase Date, become due and payable at the Option Purchase Price (plus accrued and unpaid interest, if any, to, but excluding, such Option Purchase Date) applicable thereto, and, on and after such date (unless there shall be a Default in the payment of the Option Purchase Price or such accrued and unpaid interest), such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance with this Section 3.08, the Option Purchase Price and such accrued and unpaid interest. (F) Securities with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.08 may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.08 or if there shall be a Default in the payment of the Option Purchase Price or in the accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option. -23- (G) If any Security shall not be paid upon surrender thereof for Purchase at Holder's Option, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest from, and including, the applicable Option Purchase Date at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. (H) Any Security which is to be submitted for Purchase at Holder's Option only in part shall be delivered pursuant to this Section 3.08 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Purchase at Holder's Option. (I) Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.08 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Purchase Notice) and is continuing an Event of Default (other than a Default in the payment of the Option Purchase Price or accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder's Option or a Default arising from the Company's failure to provide the applicable Option Purchase Notice). The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of an Event of Default (other than a Default in the payment of the Option Purchase Price or such accrued and unpaid interest). (J) Notwithstanding anything herein to the contrary, if the option granted to Holders to require the purchase of the Securities on the applicable Option Purchase Date is determined to constitute a tender offer, the Company shall comply with all applicable tender offer rules under the Exchange Act, including Rule 13e-4 and Regulation 14E, and with all other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws. 3.09 REPURCHASE AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE. (A) In the event any Fundamental Change (as defined below) shall occur, each Holder of Securities shall have the right (the "FUNDAMENTAL CHANGE REPURCHASE RIGHT"), at such Holder's option, to require the Company to repurchase all of such Holder's Securities (or portions thereof that are integral multiples of $1,000 in principal amount), on a date selected by the Company (the "FUNDAMENTAL CHANGE REPURCHASE DATE"), which Fundamental Change Repurchase Date shall be no later than thirty (30) days after the date the Fundamental Change Notice (as defined below) is mailed in accordance with Section 3.09(B), at a price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities (or portions thereof) to be so repurchased (the "FUNDAMENTAL CHANGE REPURCHASE PRICE"), plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, upon: -24- (i) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice, no later than 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the Fundamental Change Repurchase Date, of a Purchase Notice, in the form set forth in the Securities (or any other form of written notice delivered in good faith and substantially similar thereto), duly completed and signed, with appropriate signature guarantee, stating: (a) the certificate number(s) of the Securities which the Holder will deliver to be repurchased, if such Securities are in the form of Physical Securities; (b) the principal amount of Securities to be repurchased, which must be $1,000 or an integral multiple thereof; and (c) that such principal amount of Securities are to be repurchased pursuant to the terms and conditions specified in paragraph 9 of the Securities and in this Indenture; and (ii) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice, at any time after the delivery of such Purchase Notice, of such Securities (such Securities to conform in all material respects to the description thereof in the related Purchase Notice), together with all necessary endorsements, with respect to which the Fundamental Change Repurchase Right is being exercised, such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor plus accrued and unpaid interest, if any, payable as herein provided upon Repurchase Upon Fundamental Change. If such Securities are held in book-entry form through the Depositary, the Purchase Notice shall comply with applicable procedures of the Depositary. Upon such delivery of Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled to receive from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery. Notwithstanding anything herein to the contrary, any Holder that has delivered the Purchase Notice contemplated by this Section 3.09(A) to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice shall have the right to withdraw such Purchase Notice by delivery, at any time prior to 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the Fundamental Change Repurchase Date, of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying Agent, which notice shall contain the information specified in Section 3.09(B)(xi). The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof. -25- (B) Within thirty (30) days after the occurrence of a Fundamental Change, the Company shall mail, or cause to be mailed, to all Holders of record of the Securities at their addresses shown in the register of the Registrar, and to beneficial owners as required by applicable law, a notice (the "FUNDAMENTAL CHANGE NOTICE") of the occurrence of such Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The Company shall deliver a copy of the Fundamental Change Notice to the Trustee and shall publicly announce, through a reputable national newswire service, the occurrence of each Fundamental Change. Each Fundamental Change Notice shall state: (i) the events causing the Fundamental Change; (ii) the date of such Fundamental Change; (iii) the Fundamental Change Repurchase Date; (iv) the date by which the Fundamental Change Repurchase Right must be exercised; (v) the Fundamental Change Repurchase Price plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date; (vi) the names and addresses of the Paying Agent and the Conversion Agent; (vii) a description of the procedures which a Holder must follow to exercise the Fundamental Change Repurchase Right; (viii) that, in order to exercise the Fundamental Change Repurchase Right, the Securities (together with all necessary endorsements) must be surrendered for payment of the Fundamental Change Repurchase Price plus accrued and unpaid interest, if any, payable as herein provided upon Repurchase Upon Fundamental Change; (ix) that the Fundamental Change Repurchase Price, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, for any Security as to which a Purchase Notice has been given and not withdrawn will be paid as promptly as practicable, but in no event more than three (3) Business Days, following the later of such Fundamental Change Repurchase Date and the time of delivery of the Security (together with all necessary endorsements) as described in clause (VIII) above; (x) that, on and after such Fundamental Change Repurchase Date (unless there shall be a Default in the payment of such Fundamental Change Repurchase Price or such accrued and unpaid interest), interest on Securities subject to Repurchase Upon Fundamental Change will cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive, upon surrender of such -26- Securities (together with all necessary endorsements), the Fundamental Change Repurchase Price and such accrued and unpaid interest; (xi) that a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent), or the Paying Agent receives, prior to 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the Fundamental Change Repurchase Date, or such longer period as may be required by law, a letter or telegram, telex or facsimile transmission (receipt of which is confirmed and promptly followed by a letter) setting forth (I) the name of such Holder, (II) a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change, (III) the certificate number of such Securities to be so withdrawn (if such Securities are in the form of Physical Securities), (IV) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and (V) the principal amount, if any, of the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.09, which amount must be $1,000 or an integral multiple thereof; (xii) the Conversion Rate and any adjustments to the Conversion Rate that will result from such Fundamental Change; (xiii) that Securities with respect to which a Purchase Notice is given by a Holder may be converted pursuant to Article X only if such Purchase Notice has been withdrawn in accordance with this Section 3.09 or if there shall be a Default in the payment of the Fundamental Change Repurchase Price or in the accrued and unpaid interest, if any, payable as herein provided upon Repurchase Upon Fundamental Change; and (xiv) the CUSIP number or numbers, as the case may be, of the Securities. At the Company's request, upon reasonable prior notice, the Trustee shall mail such Fundamental Change Notice in the Company's name and at the Company's expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by the Company. No failure of the Company to give a Fundamental Change Notice shall limit any Holder's right pursuant hereto to exercise a Fundamental Change Repurchase Right. (C) Subject to the provisions of this Section 3.09, the Company shall pay, or cause to be paid, the Fundamental Change Repurchase Price, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, with respect to each Security as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof as promptly as practicable, but in no event more than three (3) Business Days, following the later of the Fundamental Change Repurchase Date and the time such Security is surrendered to the Paying Agent. -27- (D) Prior to 11:00 A.M., New York City time on a Fundamental Change Repurchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on the Fundamental Change Repurchase Date, sufficient to pay the Fundamental Change Repurchase Price, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, of all of the Securities that are to be repurchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. (E) Once the Fundamental Change Notice and the Purchase Notice have been duly given in accordance with this Section 3.09, the Securities to be repurchased pursuant to a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable at the Fundamental Change Repurchase Price (plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date) applicable thereto, and, on and after such date (unless there shall be a Default in the payment of the Fundamental Change Repurchase Price or such accrued and unpaid interest), such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance with this Section 3.09, the Fundamental Change Repurchase Price and such accrued and unpaid interest. (F) Securities with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.09 may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.09 or if there shall be a Default in the payment of the Fundamental Change Repurchase Price or in the accrued and unpaid interest, if any, payable as herein provided upon Repurchase Upon Fundamental Change. (G) If any Security shall not be paid upon surrender thereof for Repurchase Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, from, and including, the Fundamental Change Repurchase Date at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. (H) Any Security which is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section 3.09 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly submitted for Repurchase Upon Fundamental Change. (I) Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.09 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Purchase Notice) and is -28- continuing an Event of Default (other than a Default in the payment of the Fundamental Change Repurchase Price or accrued and unpaid interest, if any, payable as herein provided upon Repurchase Upon Fundamental Change or a Default arising from the Company's failure to provide the applicable Fundamental Change Notice). The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of an Event of Default (other than a Default in the payment of the Fundamental Change Repurchase Price or such accrued and unpaid interest). (J) Notwithstanding anything herein to the contrary, if the option granted to Holders to require the repurchase of the Securities upon the occurrence of a Fundamental Change is determined to constitute a tender offer, the Company shall comply with all applicable tender offer rules under the Exchange Act, including Rule 13e-4 and Regulation 14E, and with all other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws. (K) As used herein and in the Securities, a "FUNDAMENTAL CHANGE" shall be deemed to have occurred upon the occurrence, on or after the Issue Date, of either a "Change in Control" or a "Termination of Trading." (i) A "CHANGE IN CONTROL" shall be deemed to have occurred at such time as: (a) any "person" or "group" (as such terms are used for purposes of Sections 13(d) and 14(d) of the Exchange Act), other than the Company, any Subsidiary or any employee benefit plan of the Company, is or becomes the "beneficial owner" (as such term is used in Rule 13d-3 under the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the Voting Stock of the Company (such an event, an "ACQUISITION OF VOTING CONTROL"); or (b) there occurs a sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company to any "person" or "group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act), including any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act (such an occurrence, a "QUALIFYING ASSET SALE"); or (c) the Company consolidates with, or merges with or into, another person or any person consolidates with, or merges with or into, the Company, unless either: (1) the persons that "beneficially owned" (as such term is used in Rule 13d-3 under the Exchange Act), directly or indirectly, the shares of the Company's Voting Stock immediately prior to such consolidation or merger, "beneficially own," directly or indirectly, immediately after such consolidation or merger, shares of the surviving or continuing corporation's Voting Stock representing at least a majority of the total voting power of all outstanding classes of the Voting Stock of the -29- surviving or continuing corporation in substantially the same proportion as such ownership immediately prior to such consolidation or merger; or (2) at least ninety percent (90%) of the consideration (other than cash payments for fractional shares or pursuant to statutory appraisal rights) in such consolidation or merger consists of common stock and any associated rights traded on a U.S. national securities exchange or quoted on the Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such consolidation or merger), and, as a result of such consolidation or merger, the Securities become convertible solely into such common stock, associated rights and cash for fractional shares (such a consolidation or merger that does not satisfy the conditions set forth in the immediately preceding clauses (1) or (2), a "QUALIFYING BUSINESS COMBINATION"); or (d) the following persons cease for any reason to constitute a majority of the Company's Board of Directors: (1) individuals who on the Issue Date constituted the Company's Board of Directors; and (2) any new directors whose election to the Company's Board of Directors or whose nomination for election by the Company's stockholders was approved by at least a majority of the directors of the Company then still in office either who were directors of the Company on the Issue Date or whose election or nomination for election was previously so approved; or (e) the Company is liquidated or dissolved or the holders of the Company's Capital Stock approve any plan or proposal for the liquidation or dissolution of the Company. (ii) A "TERMINATION OF TRADING" shall be deemed to occur if the Common Stock of the Company (or other common stock into which the Securities are then convertible) is neither listed for trading on a U.S. national securities exchange nor approved for trading on an established automated over-the-counter trading market in the United States. (iii) Notwithstanding any provision of Section 3.09(K)(i)(b) to the contrary, a strategic licensing arrangement, or a corporate partnering transaction or similar collaboration, involving one or more of the Company's product candidates, products or intellectual property, whether in a single transaction or a series of transactions, shall be deemed not to be a Qualifying Asset Sale if: (a) the Company has obtained an opinion of a nationally recognized counsel reasonably satisfactory to the Trustee, dated the effective date of such -30- transaction or series of transactions, addressed to the Trustee and in form and substance reasonably satisfactory to the Trustee, to the effect that such transaction or series of transactions does not, individually or in the aggregate, constitute a sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company to any "person" or "group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act), including any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act; and (b) at the effective time of such transaction or series of transactions, a court of competent jurisdiction has not rendered a judgment or order that is binding on the Company and that prohibits the Company from proceeding with such transaction or series of transactions on the terms then proposed or that requires the Company to obtain the authorization or consent of the Company's stockholders in connection with such transaction or series of transactions pursuant to Section 271 of the Delaware General Corporation Law or any similar law that may then be applicable to the Company. A transaction or series of transactions that satisfies the requirements of this Section 3.09(K)(iii) is herein referred to as a "PERMITTED STRATEGIC TRANSACTION." 3.10 CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. In connection with a Redemption of Securities, the Company may arrange, in lieu of Redemption, for the purchase and conversion of any Securities called for Redemption by an agreement with one or more investment banks or other purchasers to purchase all or a portion of such Securities by paying, on or before 11:00 A.M., New York City time on the Redemption Date, to the Paying Agent in trust for the Holders whose Securities are to be so purchased, an amount of money, in funds immediately available on the Redemption Date, that, together with any amounts deposited with the Paying Agent by the Company for Redemption of such Securities, is not less than the aggregate Redemption Price, together with accrued and unpaid interest, if any, to, but excluding, the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article III, the obligation of the Company to pay the Redemption Price of such Securities, including all accrued interest, if any, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers, but no such agreement shall relieve the Company of its obligation to pay such Redemption Price or such accrued and unpaid interest, if any. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article X) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose Securities are selected for Redemption any such amount paid to it for purchase and conversion in the same manner as it would moneys deposited with it by the Company for the Redemption of Securities. Without the prior written consent of the Trustee and the Paying Agent, no arrangement between the Company and such purchasers for the purchase -31- and conversion of any Securities shall increase or otherwise affect any of the powers, duties, rights, immunities, responsibilities or obligations of the Trustee or Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the Trustee and Paying Agent from, and hold them harmless against, any and all loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses (including counsel fees and expenses) incurred by the Trustee or Paying Agent in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of their powers, duties, responsibilities or obligations under this Indenture except to the extent arising from their bad faith, willful misconduct or negligence. IV. COVENANTS 4.01 PAYMENT OF SECURITIES. The Company shall pay all amounts due with respect to the Securities on the dates and in the manner provided in the Securities and this Indenture, which amounts, if payable hereunder in cash, shall be paid (A) in the case of a Security that is in global form, by wire transfer of immediately available funds to the account specified by the Holder hereof; or (B) in the case a Security is held, other than global form, by a Holder who is the record holder of more than five million dollars ($5,000,000) aggregate principal amount of Securities, by wire transfer of immediately available funds to the account specified by such Holder or, if no such account is specified, or if such Security is held, other than in global form, by a Holder who is the record holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by mailing a check to such Holder's address shown in the register of the Registrar. All such amounts shall be considered paid on the date due if the Paying Agent holds (or, if the Company is acting as Paying Agent, the Company has segregated and holds in trust in accordance with Section 2.04) on that date money sufficient to pay the amount then due with respect to the Securities (unless there shall be a Default in the payment of such amounts to the respective Holder(s)). The Company shall pay interest on any overdue amount (including, to the extent permitted by applicable law, overdue interest) at the rate borne by the Securities. 4.02 MAINTENANCE OF OFFICE OR AGENCY. The Company will maintain, or cause to be maintained, in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-Registrar) where Securities may be surrendered for registration of transfer or exchange, payment or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. -32- The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain, or cause to be maintained, an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates the Corporate Trust Office of the Trustee as an agency of the Company in accordance with Section 2.03. 4.03 RULE 144A INFORMATION AND ANNUAL REPORTS. (A) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, provided any of the Securities or shares of Common Stock issuable upon conversion thereof shall, at such time, constitute "restricted securities" within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon request, provide to any Holder, beneficial owner or prospective purchaser of Securities or shares of Common Stock issued upon conversion of any Securities, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Securities or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial holder of such Securities or shares of Common Stock may reasonably request in writing to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time. (B) The Company shall, in accordance with TIA Section 314(a), deliver to the Trustee, within thirty (30) calendar days after the Company files such annual reports, information, documents and other reports with the SEC, copies of the Company's annual reports (which shall contain audited financial statements of the Company) and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, that the Company shall not be required to deliver to the Trustee any material for which the Company has sought and received confidential treatment by the SEC. In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, the Company shall continue to provide the Trustee and to each Holder, within thirty (30) calendar days after the date the Company would have been required to file such reports with the SEC, annual and quarterly consolidated financial statements substantially equivalent to financial statements that would have been included in reports filed with the SEC if the Company were subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, including, with respect to annual information only, a report thereon by the Company's certified independent public accountants as such would be required in such reports filed with the SEC and, in each case, together with a management's discussion and analysis of financial condition and results of operations which would be so required. The Company also shall comply with the other provisions of TIA Section 314(a). -33- 4.04 COMPLIANCE CERTIFICATE. The Company shall deliver to the Trustee, within one hundred and twenty (120) calendar days after the end of each fiscal year of the Company, an Officer's Certificate stating whether or not the signatory to such Officer's Certificate has actual knowledge of any Default or Event of Default by the Company in performing any of its obligations under this Indenture or the Securities. If such signatory does know of any such Default or Event of Default, then such certificate shall describe such Default or Event of Default and its status. 4.05 STAY, EXTENSION AND USURY LAWS. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (in each case, to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 4.06 CORPORATE EXISTENCE. Subject to Article V, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of each of its Subsidiaries, in accordance with the respective organizational documents of the Company and of each Subsidiary, and the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate existence of any Subsidiary, if in the good faith judgment of the Board of Directors (i) such preservation or existence is not material to the conduct of business of the Company and (ii) the loss of such right, license or franchise or the dissolution of such Subsidiary does not have a material adverse impact on the Holders. 4.07 NOTICE OF DEFAULT. Upon the Company's becoming aware of the occurrence of any Default or Event of Default, the Company shall give prompt written notice of such Default or Event of Default, and any remedial action proposed to be taken, to the Trustee. 4.08 FURTHER INSTRUMENTS AND ACTS.

The Company shall not consolidate with, or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the property or assets of the Company to, another person, whether in a single transaction or series of related transactions, unless: (A) either: (i) such transaction or series of related transactions shall be a merger or consolidation where the Company shall be the surviving corporation; or (ii) the surviving, resulting or transferee person both (a) is a corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia; and (b) assumes by supplemental indenture all the obligations of the Company under the Securities and this Indenture; and (B) immediately after giving effect to such transaction or series of related transactions, no Default or Event of Default shall exist. The Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officer's Certificate to the foregoing effect and an Opinion of Counsel (which may rely upon (i) such Officer's Certificate as to the absence of Defaults and Events of Default and (ii) a certificate of the appropriate official of the jurisdiction in which any such surviving, resulting or transferee person is organized certifying that such person is a corporation organized in such jurisdiction) stating that the proposed transaction and such supplemental indenture will, upon consummation of the proposed transaction, comply with this Article V and with Articles IX and X and that all conditions precedent herein provided to such transaction have been satisfied. For purposes of this Section 5.01, a Permitted Strategic Transaction shall be deemed not to be a sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company to another person. 5.02 SUCCESSOR SUBSTITUTED. Upon any consolidation, merger or any sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company, the successor person formed by such consolidation or into which the Company is merged or to which such sale, transfer, lease, conveyance or other disposition is made shall succeed to, and, except in the case of a lease, be substituted for, and may exercise every right and power of, and shall assume every duty and obligation of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein. When the successor assumes all obligations of the Company hereunder, except in the case of a lease, all obligations of the predecessor shall terminate. -35- VI. DEFAULTS AND REMEDIES 6.01 EVENTS OF DEFAULT. An "EVENT OF DEFAULT" occurs if: (i) the Company defaults in the payment of the principal of, or premium, if any, on, any Security when the same becomes due and payable, whether at maturity, upon Redemption, on an Option Purchase Date with respect to a Purchase at Holder's Option, on a Fundamental Change Repurchase Date with respect to a Repurchase Upon Fundamental Change or otherwise; (ii) the Company defaults in the payment of an installment of interest or additional interest on any Security when due, if such failure continues for thirty (30) days after the date when due; (iii) the Company fails to satisfy its conversion obligations upon exercise of a Holder's conversion rights pursuant hereto; (iv) the Company fails to timely provide a Fundamental Change Notice, or an Option Purchase Notice, as required by the provisions of this Indenture; (v) the Company fails to comply with any other term, covenant or agreement set forth in the Securities or this Indenture and such failure continues for the period, and after the notice, specified below; (vi) the Company or any of its Subsidiaries defaults in the payment when due, after the expiration of any applicable grace period, of principal of, or premium, if any, or interest on, Indebtedness of the Company or any Subsidiary for money borrowed, in the aggregate principal amount then outstanding of ten million dollars ($10,000,000) or more, or the acceleration of Indebtedness of the Company or any of its Subsidiaries for money borrowed in such aggregate principal amount or more so that it becomes due and payable prior to the date on which it would otherwise become due and payable and such default is not cured or waived, or such acceleration is not rescinded, within sixty (60) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five percent (25%) in the aggregate principal amount of the Securities then outstanding, each in accordance with this Indenture; (vii) the Company or any of its Significant Subsidiaries (or, within any period of one (1) year, each of two (2) or more Subsidiaries that, in the aggregate, would constitute a Significant Subsidiary of the Company), pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either: (A) commences a voluntary case, -36- (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors; or (viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company or any of its Significant Subsidiaries in an involuntary case or proceeding, or adjudicates the Company or any of its Significant Subsidiaries insolvent or bankrupt, (B) appoints a Custodian of the Company or any of its Significant Subsidiaries for all or substantially all of the property of the Company or any such Significant Subsidiary, as the case may be, or (C) orders the winding up or liquidation of the Company or any of its Significant Subsidiaries, and, in the case of each of the foregoing clauses (A), (B) and (C) of this Section 6.01(viii), the order or decree remains unstayed and in effect for at least ninety (90) consecutive days (provided, that there shall be deemed to occur an Event of Default pursuant to this Section 6.01(viii) if, during any single period of (90) consecutive days, there shall have remained unstayed any one or more such orders or decrees with respect to two (2) or more Subsidiaries that, in the aggregate, would constitute a Significant Subsidiary of the Company). The term "BANKRUPTCY LAW" means Title 11, U.S. Code or any similar Federal or U.S. State law for the relief of debtors. The term "CUSTODIAN" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. A Default under clause (v) above is not an Event of Default until (I) the Trustee notifies the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, of the Default and (II) the Default is not cured within sixty (60) days after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that the notice is a "NOTICE OF DEFAULT." If the Holders of at least twenty five percent (25%) in aggregate principal amount of the outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for every purpose under this Indenture. 6.02 ACCELERATION. If an Event of Default (excluding an Event of Default specified in Section 6.01(vii) or (viii) with respect to the Company (but including an Event of Default specified in Section 6.01(vii) or (viii) solely with respect to a Significant Subsidiary of the Company or any group of -37- Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding by notice to the Company and the Trustee, may declare the Securities to be immediately due and payable in full. Upon such declaration, the principal of, and any premium and accrued and unpaid interest (including any additional interest) on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(vii) or (viii) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(vii) or (viii) solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and any premium and accrued and unpaid interest (including any additional interest) on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if (A) the rescission would not conflict with any governmental or court order or decree, (B) all existing Events of Default, except the nonpayment of principal, premium, if any, or interest that has become due solely because of the acceleration, have been cured or waived and (C) all amounts due to the Trustee under Section 7.07 have been paid. 6.03 OTHER REMEDIES. Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative. 6.04 WAIVER OF PAST DEFAULTS. Subject to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding may, by notice to the Trustee, waive any past Default or Event of Default and its consequences, other than (A) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest or additional interest on, any Security, or in the payment of the Redemption Price, the Option Purchase Price or the Fundamental Change Repurchase Price (or accrued and unpaid interest, if any, payable as herein provided, upon Redemption, Purchase at Holder's Option or Repurchase Upon Fundamental Change), (B) a Default or Event of Default arising from a failure by the Company to convert any Securities into shares of Common Stock in accordance with this Indenture or (C) any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each outstanding Security affected. When a Default or an Event of Default is waived, it is cured and ceases to exist for -38- every purpose of this indenture; provided, however, that no waiver of a Default or Event of Default shall extend to any subsequent or other Default or Event of Default or impair any consequent right. This Section 6.04 shall be in lieu of TIA Section 316(a)(1)(B), and, as permitted by the TIA, TIA Section 316(a)(1)(B) is hereby expressly excluded from this Indenture. 6.05 CONTROL BY MAJORITY. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity reasonably satisfactory to it; provided, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. This Section 6.05 shall be in lieu of TIA Section 316(a)(1)(A), and, as permitted by the TIA, TIA Section 316(a)(1)(A) is hereby expressly excluded from this Indenture. 6.06 LIMITATION ON SUITS. Except as provided in Section 6.07, a Securityholder may not institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under this Indenture unless: (i) the Holder gives to the Trustee written notice of a continuing Event of Default; (ii) the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy; (iii) such Holder or Holders offer and, if requested, provide to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense to or of the Trustee in connection with pursuing such remedy; (iv) the Trustee does not comply with the request within sixty (60) days after receipt of such notice, request and offer of indemnity; and (v) during such sixty (60) day period, the Holders of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction inconsistent with the request. A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. 6.07 RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of all amounts due with respect to the Securities, on or after the respective due dates as -39- provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. Notwithstanding any other provision of this Indenture, the right of any Holder to bring suit for the enforcement of the right to convert the Security in accordance with this Indenture shall not be impaired or affected without the consent of the Holder. 6.08 COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 6.01(i) or (ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest. 6.09 TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may 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, any predecessor Trustee and the Securityholders allowed in any judicial proceedings relative to the Company or its creditors or properties. The Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 6.10 PRIORITIES. If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07; Second: to Securityholders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and payable on the Securities; and Third: the balance, if any, to the Company. -40- The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment by it to Securityholders pursuant to this Section 6.10. At least fifteen (15) days before each such record date, the Trustee shall mail to each Holder and the Company a written notice that states such record date and payment date and the amount of such payment. 6.11 UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities. VII. TRUSTEE 7.01 DUTIES OF TRUSTEE. (A) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. (B) Except during the continuance of an Event of Default: (i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith, willful misconduct or negligence on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). (C) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: -41- (i) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (ii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. (D) Every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.01. (E) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee shall be segregated from other funds, as directed by the Company or as required by law, and shall be invested by the Trustee pursuant to the written instructions of the Company reasonably satisfactory to the Trustee; provided, however, that the Trustee shall have no liability hereunder with respect to any such investment, other than by reason of the willful misconduct or negligence of the Trustee; provided further, that in no event shall the Trustee be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits) with respect to such investments, even if the Trustee has been advised of the likelihood of such loss or damage; provided further, that nothing in this Section 7.01(E) shall affect the Company's obligations to make all payments due under the Securities. 7.02 RIGHTS OF TRUSTEE. (A) Subject to Section 7.01, the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document; if, however, the Trustee shall determine to make such further inquiry or investigation, it shall be entitled during normal business hours of the Company to examine the relevant books, records and premises of the Company, personally or by agent or attorney upon reasonable prior notice. (B) Before the Trustee acts or refrains from acting, it may require an Officer's Certificate and/or an Opinion of Counsel which conforms to the requirements of Section 11.05. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer's Certificate or Opinion of Counsel. (C) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution.

Delivery of reports, information and documents to the Trustee under Article IV (other than Sections 4.04 and 4.07) is for informational purposes only and the Trustee's receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely on Officer's Certificates). (H) Subject to Section 7.01(A), the Trustee shall be under no obligation to exercise any of the rights or powers vested by this Indenture at the request or direction of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. (I) 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.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights the Trustee would have if it were not Trustee. Any Security Agent may do the same with like rights. The Trustee, however, must comply with Sections 7.10 and 7.11. 7.04 TRUSTEE'S DISCLAIMER. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities; the Trustee shall not be accountable for the Company's use of the proceeds from the Securities, for the Company's performance hereunder or for the Company's representations and warranties contained herein; and the Trustee shall not be responsible for any statement in the Securities (other than the Trustee's certificate of authentication), the Shelf Registration Statement (other than any statement of eligibility executed by the Trustee and filed with the -43- Shelf Registration Statement pursuant to Item 601(b)(25) of Regulation S-K promulgated under the Securities Act) or any other offering document related to the Securities. 7.05 NOTICE OF DEFAULTS. If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of this Indenture, or as to which a Responsible Officer of the Trustee shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within thirty (30) days after the Trustee has received such notice or after such Responsible Officer shall have acquired such actual knowledge, whichever is earlier, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment of any amounts due with respect to any Security, the Trustee may withhold such notice if, and so long as it in good faith determines that, withholding such notice is in the best interests of Holders. 7.06 REPORTS BY TRUSTEE TO HOLDERS. Within sixty (60) days after each May 15, beginning with May 15, 2005, the Trustee shall mail to each Securityholder, pursuant to Section 11.02, if required by TIA Section 313(a) a brief report dated as of such May 15 that complies with TIA Section 313. A copy of each report at the time of its mailing to Securityholders shall be mailed by first class mail to the Company and filed by the Trustee with the SEC and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee of the listing or delisting of the Securities on or from any stock exchange. 7.07 COMPENSATION AND INDEMNITY. The Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed upon in writing. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust.

The Company need not pay for any settlement made without its consent. The Trustee shall notify the Company promptly of any claim for which it may seek indemnification. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee's negligence, bad faith or willful misconduct. -44- To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay amounts due on particular Securities. The indemnity obligations of the Company with respect to the Trustee provided for in this Section 7.07 shall survive any resignation or removal of the Trustee. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(vii) or (viii) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 7.08 REPLACEMENT OF TRUSTEE. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 7.08. The Trustee may resign by so notifying the Company in writing thirty (30) Business Days prior to such resignation. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor Trustee with the Company's consent. The Company may remove the Trustee if: (i) the Trustee fails to comply with Section 7.10; (ii) the Trustee is adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. If a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company's expense), the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 7.10, the Company or any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the -45- Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 7.09 SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee, if such successor corporation is otherwise eligible hereunder. 7.10 ELIGIBILITY; DISQUALIFICATION.

This Indenture shall cease to be of further effect if (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 2.07 hereof) have been delivered to the Trustee for cancellation or (ii) all outstanding Securities have become due and payable at their scheduled maturity or upon Purchase at Holder's Option, Redemption or Repurchase Upon Fundamental Change, and in either case the Company irrevocably deposits, prior to the applicable due date, with the Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) cash, and, if applicable as herein provided and in accordance herewith, such other consideration, sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07 hereof) on the Maturity Date or an Option Purchase Date, Redemption Date or Fundamental Change Repurchase Date, as the case may be; (b) the Company pays to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event of Default with respect to the Securities shall exist on the date of such deposit; (d) such deposit will not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture or any other -46- agreement or instrument to which the Company is a party or by which it is bound; and (e) the Company has delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied with; provided, however, that Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.15, 2.16, 2.17, 3.05, 3.08, 3.09, 4.01, 4.02, 4.05, 7.07 and 7.08 and Articles VIII and X shall survive any discharge of this Indenture until such time as the Securities have been paid in full and there are no Securities outstanding. 8.02 APPLICATION OF TRUST MONEY. The Trustee shall hold in trust all money and other consideration deposited with it pursuant to Section 8.01 and shall apply such deposited money and other consideration through the Paying Agent and in accordance with this Indenture to the payment of the amounts due on the Securities. 8.03 REPAYMENT TO COMPANY. The Trustee and the Paying Agent shall promptly notify the Company of, and pay to the Company upon the written request of the Company, any excess money held by them at any time. The Trustee or the Paying Agent, as the case may be, shall provide written notice to the Company of any money that has been held by it and has, for a period of two (2) years, remained unclaimed for the payment of the principal of, or any accrued and unpaid interest on, the Securities. The Trustee and the Paying Agent shall pay to the Company, upon the written request of the Company, any money held by them for the payment of the principal of, premium, if any, or any accrued and unpaid interest or additional interest on, the notes that remains unclaimed for two (2) years; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published once in a newspaper of general circulation in the City of New York or cause to be mailed to each Holder, in accordance with Section 11.02, notice stating that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Securityholders entitled to the money must look to the Company for payment as general creditors, subject to applicable law, and all liability of the Trustee and the Paying Agent with respect to such money and payment shall, subject to applicable law, cease. 8.04 REINSTATEMENT. If the Trustee or Paying Agent is unable to apply any money or other consideration in accordance with Sections 8.01 and 8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Sections 8.01 and 8.02 until such time as the Trustee or Paying Agent is permitted to apply all such money or other consideration in accordance with Sections 8.01 and 8.02; provided, however, that if the Company has made any payment of amounts due with respect to any Securities because of the reinstatement of its obligations, then the Company shall be subrogated to the rights of the -47- Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. IX. AMENDMENTS 9.01 WITHOUT CONSENT OF HOLDERS. The Company, with the consent of the Trustee, may amend or supplement this Indenture or the Securities without notice to or the consent of any Securityholder: (i) to comply with Sections 5.01 and 10.12 and, in accordance with Section 10.15(F), to give effect to an election, pursuant to such Section 10.15(F), by the Company to make an Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer Fundamental Change; (ii) to make any changes or modifications to this Indenture necessary in connection with the registration of the public offer and sale of the Securities under the Securities Act pursuant to the Registration Rights Agreement or the qualification of this Indenture under the TIA; (iii) to secure the obligations of the Company in respect of the Securities; (iv) to add to the covenants of the Company described in this Indenture for the benefit of Securityholders or to surrender any right or power conferred upon the Company; (v) to make provisions with respect to adjustments to the Conversion Rate as required by this Indenture or to increase the Conversion Rate in accordance with this Indenture; (vi) to add additional events which shall constitute an Event of Default hereunder; and (vii) to provide for a successor Trustee in accordance herewith. In addition, the Company and the Trustee may enter into a supplemental indenture without the consent of Holders of the Securities to cure any ambiguity, defect, omission or inconsistency in this Indenture in a manner that does not individually or in the aggregate adversely affect the rights of any Holder in any material respect; provided, that the Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel as to whether any such cure does not individually or in the aggregate adversely affect the rights of any Holder in any material respect. 9.02 WITH CONSENT OF HOLDERS. The Company, with the consent of the Trustee, may amend or supplement this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders -48- of at least a majority in aggregate principal amount of the outstanding Securities. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding Securities may, by notice to the Trustee, waive compliance by the Company with any provision of this Indenture or the Securities without notice to any other Securityholder. Notwithstanding anything herein to the contrary, without the consent of each Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: (a) change the stated maturity of the principal of, or the payment date of any installment of interest or any premium on, any Security; (b) reduce the principal amount of, or any premium, interest or additional interest on, any Security; (c) change the place or currency of payment of principal of, or any premium, interest or additional interest on, any Security; (d) impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security; (e) modify, in a manner adverse to Holders, the provisions with respect to the right of Holders pursuant to Article III to require the Company to purchase Securities on an Option Purchase Date or to repurchase Securities upon the occurrence of a Fundamental Change; (f) modify the provisions of Section 2.18 in a manner adverse to Holders; (g) adversely affect the right of Holders to convert Securities in accordance with Article X; (h) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification to or amendment of any provision of this Indenture or the Securities; (i) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a waiver of compliance with any provision of this Indenture or the Securities or a waiver of any Default or Event of Default; or (j) modify the provisions of this Indenture with respect to modification and waiver (including waiver of a Default or an Event of Default), except to increase the percentage required for modification or waiver or to provide for consent of each affected Holder. Promptly after an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall mail, or cause to be mailed, to Securityholders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to -49- mail such notice shall not in any way impair or affect the validity of such amendment, supplement or waiver. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 9.03 COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment, waiver or supplement to this Indenture or the Securities shall comply with the TIA as then in effect. 9.04 REVOCATION AND EFFECT OF CONSENTS. If the Company shall solicit from the Holders a consent to any amendment or supplement to the Indenture or any waiver hereunder, in each case in accordance herewith, the Company may, but shall not be obligated to, establish, by Board Resolution and delivery of an Officer's Certificate to the Trustee, a record date for the purpose of determining the Holders of record entitled to give such consent; provided, however, that (i) such record date shall not be more than fifteen (15) days prior to the first solicitation of such consent, and (ii) at least fifteen (15) days prior to such record date, the Company shall, in accordance with Section 11.02, mail, or cause to be mailed, by first class mail a notice of such record date to each Holder and shall publicly disseminate a press release through a reputable national newswire service, disclosing such record date. If a record date is so fixed in accordance herewith, then (A) only the Holders of record at 5:00 p.m., New York City time, on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Securities have consented to such amendment, supplement or waiver, and for that purpose the outstanding Securities shall be computed as of such record date; and (B) those persons who were Holders as of 5:00 p.m., New York City time, on such record date (or their duly designated proxies), and only those persons, shall be entitled to revoke any consent previously given, whether or not any such person continues to be a Holder after such record date; provided, however, that no such consent by the Holders on such record date shall be effective unless the applicable amendment, supplement or waiver shall become effective pursuant to the provisions hereof no later than six (6) months after such record date. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or, except as provided in the immediately preceding paragraph, subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. After an amendment, supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder (including subsequent Holders) unless such amendment, supplement or waiver makes a change that requires, pursuant to Section 9.02, the consent of each -50- Holder affected. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and, provided that notice of such amendment, supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder's Security, every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. Nothing in this Section 9.04 shall impair the Company's rights pursuant Section 9.01(i) to amend this Indenture or the Securities without the consent of any Securityholder in the manner set forth in, and permitted by, such Section 9.01(i). 9.05 NOTATION ON OR EXCHANGE OF SECURITIES. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. 9.06 TRUSTEE PROTECTED. The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article IX; provided, however, that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article IX that adversely affects the Trustee's rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel as to legal matters and an Officer's Certificate as to factual matters that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture. 9.07 EFFECT OF SUPPLEMENTAL INDENTURES. Upon the due execution and delivery of any supplemental indenture in accordance with this Article IX, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and, except as set forth in Sections 9.02 and 9.04, every Holder of Securities shall be bound thereby. X. CONVERSION 10.01 CONVERSION PRIVILEGE; RESTRICTIVE LEGENDS. (A) Subject to the provisions of Article III, the Securities shall be convertible into shares of Common Stock in accordance with this Article X at any time prior to stated maturity, upon the satisfaction of the conditions set forth in the second paragraph of paragraph 10 of the Securities. -51- (B) The initial Conversion Rate shall be 92.9023 shares of Common Stock per $1,000 principal amount of Securities. The Conversion Rate shall be subject to adjustment in accordance with Sections 10.06 through 10.15. (C) A Holder may convert a portion of the principal amount of a Security if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of it. (D) Any shares of Common Stock that are issued upon conversion of a Security shall bear the Private Placement Legend until the earlier of the second anniversary of the later of the Issue Date and the last date on which the Company or any Affiliate was the owner of such shares or the Security (or any predecessor security) from which such shares were converted (or such shorter period of time as permitted by Rule 144(k) under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as set forth in an Opinion of Counsel, unless otherwise agreed by the Company and the Holder thereof). 10.02 CONVERSION PROCEDURE. (A) To convert a Security, a Holder must satisfy the requirements of paragraph 10 of the Securities. As soon as practicable following the date (the "CONVERSION DATE") on which the Holder satisfies all those requirements, the Company shall deliver to the Holder through the Conversion Agent a certificate for the number of full shares of Common Stock issuable upon the conversion, as provided in paragraph 10 of the Securities, and a check for the amount of cash payable in lieu of any fractional share; provided, however, that any Make-Whole Consideration payable pursuant to Section 10.15 shall be delivered by the Company within the time period specified in Section 10.15(D). Immediately before the close of business on the Conversion Date, and thereafter, the person in whose name such certificate is to be registered shall be treated as a stockholder of record of the Company, and all rights of the Holder of the Security to be converted shall terminate, other than the right to receive the shares of Common Stock and cash deliverable as provided in the preceding sentence. A Holder of Securities is not entitled, as such, to any rights of a holder of Common Stock until such Holder has converted its Securities into shares of Common Stock, or is deemed to be a stockholder of record of the Company, as provided in this Section 10.02(A), and then only to the extent such Securities are deemed to have been so converted or such Holder is so deemed to be a stockholder of record. If a Security is duly surrendered for conversion in accordance herewith, the Company shall have fully satisfied its obligations with respect to such Security once the Company shall have duly delivered, in accordance herewith, both (i) the shares of Common Stock, together with any cash payment for fractional shares, due hereunder upon such conversion; and (ii) if such Security shall have been surrendered for such conversion after the close of business on the record date for the payment pursuant hereto of an installment of interest but before the related interest payment date, such installment of interest. (B) Except as provided in the Securities or in this Article X, no payment or adjustment will be made for accrued interest on, or additional interest with respect to, a -52- converted Security or for dividends on any Common Stock issued on or prior to conversion. If any Holder surrenders a Security for conversion after the close of business on the record date for the payment of an installment of interest and prior to the related interest payment date, then, notwithstanding such conversion, the interest payable with respect to such Security on such interest payment date shall be paid on such interest payment date to the Holder of record of such Security at the close of business on such record date; provided, however, that such Security, when surrendered for conversion, must be accompanied by payment in cash to the Conversion Agent on behalf of the Company of an amount equal to the interest payable on such interest payment date on the portion so converted; provided further, however, that such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for conversion shall not be required if such Security is called for Redemption pursuant to Section 3.04 and paragraphs 6 and 7 of the Securities; provided further, that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such Security, then in no event shall the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted interest or the interest that shall have accrued on such defaulted interest pursuant to Section 2.12 or otherwise (it being understood that nothing in this Section 10.02(B) shall affect the Company's obligations under Section 2.12). (C) If a Holder converts more than one Security at the same time, the number of full shares of Common Stock issuable upon such conversion shall be based on the total principal amount of all Securities converted. (D) Upon surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered. (E) If the last day on which a Security may be converted is a Legal Holiday in a place where a Conversion Agent is located, the Security may be surrendered to that Conversion Agent on the next succeeding day that is not a Legal Holiday. 10.03 FRACTIONAL SHARES. The Company will not issue fractional shares of Common Stock upon conversion of Securities and instead will deliver a check in an amount equal to the value of such fraction computed on the basis of the Closing Sale Price on the Trading Day immediately before the Conversion Date. 10.04 TAXES ON CONVERSION. If a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of shares of Common Stock upon the conversion. However, such Holder shall pay any such tax or duty which is due because such shares are issued in a name other than such Holder's name. The Conversion Agent may refuse to deliver a certificate representing the shares of Common Stock to be issued in a name other than such Holder's name until the Conversion Agent receives a sum sufficient to pay any tax or duty -53- which will be due because such shares are to be issued in a name other than such Holder's name. Nothing herein shall preclude any tax withholding required by law or regulation. 10.05 COMPANY TO PROVIDE STOCK. The Company shall at all times reserve out of its authorized but unissued Common Stock or Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Securities into shares of Common Stock. The shares of Common Stock due upon conversion of a Global Security shall be delivered by the Company in accordance with the Depositary's customary practices. All shares of Common Stock which may be issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim. The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities and shall list such shares on each national securities exchange or automated quotation system on which the Common Stock is listed. 10.06 ADJUSTMENT OF CONVERSION RATE. The Conversion Rate shall be subject to adjustment from time to time as follows: (a) In case the Company shall (1) pay a dividend in shares of Common Stock to all holders of Common Stock, (2) make a distribution in shares of Common Stock to all holders of Common Stock, (3) subdivide the outstanding shares of Common Stock into a greater number of shares of Common Stock or (4) combine the outstanding shares of Common Stock into a smaller number of shares of Common Stock, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to close of business on the record date or effective date, as applicable, of such dividend, distribution, subdivision or combination by the number of shares of Common Stock which a person who owns only one share of Common Stock immediately before the record date or effective date, as applicable, of such dividend, distribution, subdivision or combination and who is entitled to participate in such dividend, distribution, subdivision or combination would own immediately after giving effect to such dividend, distribution, subdivision or combination (without giving effect to any arrangement pursuant to such dividend, distribution, subdivision or combination not to issue fractional shares of Common Stock). Any adjustment made pursuant to this Section 10.06(a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. (b) If the Company shall issue rights or warrants to all or substantially all holders of Common Stock, entitling them, for a period expiring not more than sixty (60) days immediately following the record date for the determination of holders of Common Stock entitled to receive such rights or warrants, to subscribe -54- for or purchase shares of Common Stock (or securities convertible into or exchangeable or exercisable for Common Stock), at a price per share (or having a conversion, exchange or exercise price per share) that is less than the current market price (as determined pursuant to Section 10.06(g)) per share of Common Stock on the record date for the determination of holders of Common Stock entitled to receive such rights or warrants, then the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which (A) the numerator shall be the sum of (I) the number of shares of Common Stock outstanding at the close of business on such record date and (II) the aggregate number of shares (the "UNDERLYING SHARES") of Common Stock underlying all such issued rights or warrants (whether by exercise, conversion, exchange or otherwise), and (B) the denominator shall be the sum of (I) number of shares of Common Stock outstanding at the close of business on such record date and (II) the number of shares of Common Stock which the aggregate exercise, conversion, exchange or other price at which the Underlying Shares may be subscribed for or purchased pursuant to such rights or warrants would purchase at such current market price. Such increase shall become effective immediately prior to the opening of business on the day following such record date. Notwithstanding the foregoing, the Company shall not be required to make an adjustment to the Conversion Rate pursuant to this Section 10.06(b) on account of a distribution of rights (whether by distribution of separate certificates representing such rights or otherwise), provided that (i) such rights are distributed pursuant to a stockholders' rights plan; and (ii) the Company makes adequate provision, on the same basis set forth in the second sentence of Section 10.06(c) with respect to Rights, and in accordance with Section 10.14, for Holders, upon conversion of Securities, to receive such rights in addition to any other consideration payable hereunder with respect to such conversion. In no event shall the Conversion Rate be decreased pursuant to this Section 10.06(b). (c) In case the Company shall dividend or distribute to all or substantially all holders of Common Stock shares of Capital Stock of the Company (other than Common Stock), evidences of Indebtedness or other assets (other than dividends or distributions requiring an adjustment to the Conversion Rate in accordance with Sections 10.06(d) or 10.06(e)), or shall dividend or distribute to all or substantially all holders of Common Stock rights or warrants to subscribe for or purchase securities of the Company (other than dividends or distributions of rights or warrants requiring an adjustment to the Conversion Rate in accordance with Section 10.06(b)), then in each such case the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date for the determination of stockholders entitled to such dividend or distribution by a fraction of which (A) the numerator shall be the current market price of Common Stock (as determined pursuant to Section 10.06(g)) on such record date and (B) the denominator shall be an amount equal to (I) such current market price less (II) the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), on such record date, of the portion of the shares of Capital Stock, evidences of Indebtedness, assets, rights and warrants to be -55- dividended or distributed applicable to one share of Common Stock, such increase to become effective immediately prior to the opening of business on the day following such record date; provided, however, that if such denominator is equal to or less than zero, then, in lieu of the foregoing adjustment to the Conversion Rate, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of its Securities, in addition to any consideration otherwise payable as herein provided upon such conversion, an amount of shares of Capital Stock, evidences of Indebtedness, assets, rights and/or warrants that such Holder would have received had such Holder converted all of its Securities on such record date. Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants (other than distributions of rights or warrants requiring an adjustment to the Conversion Rate in accordance with Section 10.06(b)) (collectively, "RIGHTS") to all or substantially all holders of Common Stock, the Company may, in lieu of making any adjustment pursuant to this Section 10.06(c), make proper provision so that each Holder of a Security who converts such Security (or any portion thereof) on or after the record date for such distribution and prior to the expiration or redemption of the Rights shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable (and cash, if any, payable) upon such conversion (the "CONVERSION SHARES"), a number of Rights to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of Rights of separate certificates evidencing such Rights (the "DISTRIBUTION DATE"), the same number of Rights to which a holder of a number of shares of Common Stock equal to the number of shares of Conversion Shares would be entitled at the time of such conversion in accordance with the terms and provisions of and applicable to the Rights; and (ii) if such conversion occurs after the Distribution Date, the same number of Rights to which a holder of the number of shares of Common Stock into which the principal amount of the Security so converted was convertible immediately prior to the Distribution Date would have been entitled on the Distribution Date in accordance with the terms and provisions of and applicable to the Rights. Any distribution of rights (whether by distribution of separate certificates representing such rights or otherwise) or warrants pursuant to a stockholders' rights plan complying with the requirements set forth in the preceding sentence of this paragraph and with Section 10.14 shall not constitute a distribution of rights or warrants pursuant to this Section 10.06(c). In no event shall the Conversion Rate be decreased pursuant to this Section 10.06(c). (d) In case the Company shall, by dividend or otherwise, at any time make a distribution of cash (excluding any cash that is distributed as part of a distribution requiring a Conversion Rate adjustment pursuant to Section 10.06(e)) to all or substantially all holders of Common Stock, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date for the determination of holders of Common Stock entitled to such distribution by a fraction (A) whose numerator shall be the current market price per share of Common Stock (as determined pursuant to Section 10.06(g)) on such record date and (B) whose denominator shall be an amount equal to (I) such current market price per share of Common Stock less (II) -56- the amount of the distribution per share of Common Stock; provided, however, that the Conversion Rate shall not be adjusted pursuant to this Section 10.06(d) to the extent, and only to the extent, such adjustment would cause the Conversion Price to be less than one cent ($0.01); provided further that, if the denominator of such fraction shall be equal to or less than zero, the Conversion Rate shall be instead adjusted so that the Conversion Price is equal to one cent ($0.01). An adjustment to the Conversion Rate pursuant to this Section 10.06(d) shall become effective immediately prior to the opening of business on the day immediately following such record date. In no event shall the Conversion Rate be decreased pursuant to this Section 10.06(d). (e) In case the Company or any Subsidiary shall distribute cash or other consideration in respect of a tender offer or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock where the sum of the aggregate amount of such cash distributed and the aggregate fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the Expiration Date (as defined below), of such other consideration distributed (such sum, the "AGGREGATE AMOUNT") expressed as an amount per share of Common Stock validly tendered or exchanged, and not withdrawn, pursuant to such tender offer or exchange offer as of the Expiration Time (as defined below) (such tendered or exchanged shares of Common Stock, the "PURCHASED SHARES") exceeds the current market price per share of Common Stock (as determined pursuant to Section 10.06(g)) on the last date (such last date, the "EXPIRATION DATE") on which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (as the same may be amended through the Expiration Date), then the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the Expiration Date by a fraction (A) whose numerator is equal to the sum of (I) the Aggregate Amount and (II) the product of (a) the current market price per share of Common Stock (as determined pursuant to Section 10.06(g)) on the Expiration Date and (b) an amount equal to (i) the number of shares of Common Stock outstanding as of the last time (the "EXPIRATION TIME") at which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (including all Purchased Shares) less (ii) the Purchased Shares and (B) whose denominator is equal to the product of (I) the number of shares of Common Stock outstanding as of the Expiration Time (including all Purchased Shares) and (II) the current market price per share of Common Stock on the Expiration Date. An increase, if any, to the Conversion Rate pursuant to this Section 10.06(e) shall become effective immediately prior to the opening of business on the Business Day following the Expiration Date. In the event that the Company or a Subsidiary is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such -57- tender offer or exchange offer had not been made. If the application of this Section 10.06(e) to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer or exchange offer under this Section 10.06(e). (f) In addition to the foregoing adjustments in Subsections (a), (b), (c), (d) and (e) above, the Company, from time to time and to the extent permitted by law and by the rules of the Nasdaq National Market, may increase the Conversion Rate by any amount for a period of at least twenty (20) days or such longer period as may be permitted by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give written notice to the Trustee and cause notice of such increase to be mailed, in accordance with Section 11.02, to each Holder of Securities, at least fifteen (15) days prior to the date on which such increase commences. (g) For the purpose of any computation under Subsections (a), (b), (c) or (d) above of this Section 10.06, the current market price per share of Common Stock on the date fixed for determination of the stockholders entitled to receive the issuance or distribution requiring such computation (the "DETERMINATION DATE") shall be deemed to be the average of the Closing Sale Prices for the ten (10) consecutive Trading Days immediately preceding the Determination Date, and, for the purpose of any computation under Section 10.06(e), the current market price per share of Common Stock on the Expiration Date for the tender offer or exchange offer requiring such computation shall be deemed to be the average of the Closing Sale Price for the ten (10) consecutive Trading Days immediately preceding the Expiration Date; provided, however, that (i) if the Ex Date for any event (other than the event requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Subsection (a), (b), (c), (d) or (e) above occurs on or after the tenth (10th) Trading Day prior to the Determination Date or Expiration Date, whichever is applicable, and prior to the Ex Date for the issuance or distribution requiring such computation, the Closing Sale Price for each Trading Day prior to the Ex Date for such other event shall be adjusted by multiplying such Closing Sale Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event, (ii) if the Ex Date for any event (other than the event requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Subsection (a), (b), (c), (d) or (e) above occurs on or after the Ex Date for the issuance or distribution requiring such computation and on or prior to the Determination Date or the Expiration Date, whichever is applicable, the Closing Sale Price for each Trading Day on and after the Ex Date for such other event shall be adjusted by multiplying such Closing Sale Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event, and (iii) if the Ex Date for the event requiring such computation is on or prior to the Determination Date or Expiration Date, whichever is applicable, after taking into account any adjustment required pursuant to clause (i) or (ii) of this -58- proviso, the Closing Sale Price for each Trading Day on and after such Ex Date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined in good faith by the Board of Directors in a manner consistent with any determination of such value for the purposes of this Section 10.06, whose determination shall be conclusive and described in a Resolution of the Board of Directors) of the evidences of Indebtedness, shares of Capital Stock or other securities or assets or cash being distributed (in the event requiring such computation) applicable to one share of Common Stock as of the close of business on the day before such Ex Date. The term "EX DATE," (i) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades the regular way on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, (ii) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades the regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (iii) when used with respect to any tender offer or exchange offer means the first date on which the Common Stock trades the regular way on such exchange or in such market after the expiration time of such tender offer or exchange offer (as it may be amended or extended). 10.07 NO ADJUSTMENT. Notwithstanding anything to the contrary in Section 10.06, no adjustment in the Conversion Rate pursuant to Section 10.06 shall be required until cumulative adjustments amount to one percent (1%) or more of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate); provided, however, that any adjustments to the Conversion Rate which by reason of this Section 10.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment to the Conversion Rate. All calculations under this Article X shall be made to the nearest cent or to the nearest one-millionth of a share, as the case may be. Notwithstanding anything to the contrary in Section 10.06, if any rights, options or warrants issued by the Company and requiring an adjustment to the Conversion Rate in accordance with Section 10.06 are only exercisable upon the occurrence of certain triggering events, then the Conversion Rate will not be adjusted as provided in Section 10.06 until the earliest of such triggering event occurs. Upon the expiration or termination of any such rights, options or warrants without the exercise of such rights, options or warrants, the Conversion Rate then in effect shall be adjusted immediately to the Conversion Rate which would have been in effect at the time of such expiration or termination had such rights, options or warrants, to the extent outstanding immediately prior to such expiration or termination, never been issued. Notwithstanding anything to the contrary in Section 10.06, if any dividend or distribution is declared and the Conversion Rate is adjusted pursuant to Section 10.06 on account of such dividend or distribution, but such dividend or distribution is thereafter not paid or made, the -59- Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect had such dividend or distribution not been declared. Notwithstanding anything to the contrary in Section 10.06, no adjustment to the Conversion Rate need be made pursuant to Section 10.06 for a transaction if Holders are to participate in the transaction without conversion on a basis and with notice that the Board of Directors determines in good faith to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction (which determination shall be described in a Board Resolution). No adjustment to the Conversion Rate need be made pursuant to Section 10.06 solely as a result of distributions or dividends solely on any preferred stock of the Company. Except as otherwise provided in this Indenture, no adjustment to the Conversion Rate shall be required pursuant to Section 10.06 for the issuance of Common Stock or the right to purchase Common Stock or any security that is convertible or exchangeable for Common Stock. 10.08 OTHER ADJUSTMENTS. In the event that, as a result of an adjustment made pursuant to Section 10.06 hereof, the Holder of any Security thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock other than shares of Common Stock, thereafter the Conversion Rate of such other shares so receivable upon conversion of any Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Article X. 10.09 ADJUSTMENTS FOR TAX PURPOSES. Except as prohibited by law or by the rules of the Nasdaq National Market, the Company may make such increases in the Conversion Rate, in addition to those required by Section 10.06 hereof, as it determines to be advisable in order to eliminate or diminish any income taxes to holders of Common Stock resulting from any stock dividend, subdivision of shares, distribution of rights to purchase stock or securities or distribution of securities convertible into or exchangeable for stock made by the Company or to its stockholders. 10.10 NOTICE OF ADJUSTMENT. Whenever the Conversion Rate is adjusted, the Company shall promptly mail, or cause there to be mailed, to Holders at the addresses appearing on the Registrar's books a notice of the adjustment and file with the Trustee an Officer's Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment. -60- 10.11 NOTICE OF CERTAIN TRANSACTIONS. In the event that: (1) the Company takes any action, or becomes aware of any event, which would require an adjustment in the Conversion Rate, (2) the Company takes any action that would require a supplemental indenture pursuant to Section 10.12, or (3) there is a dissolution or liquidation of the Company, the Company shall mail to Holders at the addresses appearing on the Registrar's books and the Trustee a written notice stating the proposed record, effective or expiration date, as the case may be, of any transaction referred to in clause (1), (2) or (3) of this Section 10.11. The Company shall mail such notice at least twenty (20) days before such date; however, failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 10.11. 10.12 EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, MERGERS, BINDING SHARE EXCHANGES OR SALES ON CONVERSION PRIVILEGE. Except as provided in Section 10.15(F), if any of the following shall occur, namely: (i) any reclassification or change in the Common Stock issuable upon conversion of Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination of the Common Stock), (ii) any consolidation, merger or binding share exchange to which the Company is a party other than a merger in which the Company is the continuing Person and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination) in, the Common Stock or (iii) any sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company, in each case pursuant to which the Common Stock would be converted into, or exchanged for, cash, securities or other property, then the Company or such successor or purchasing Person, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee providing that, at and after the effective time of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the Holder of each Security then outstanding shall have the right to convert such Security into the kind and amount of shares of stock and other securities and property (including cash), if any, receivable upon such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, assuming that such Holder would not have exercised any rights of election that such Holder would have had as a holder of Common Stock to select a particular type of consideration. Such -61- supplemental indenture shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article X. The foregoing, however, shall not in any way affect the right a Holder of a Security may otherwise have, pursuant to Section 10.06(c), Section 10.06(b) or Section 10.14, to receive rights or warrants upon conversion of a Security. If, in the case of any such consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of stock or other securities and property of a Person other than the successor or purchasing Person, as the case may be, in such consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors in good faith shall reasonably determine necessary by reason of the foregoing (which determination shall be described in a Board Resolution). The provisions of this Section 10.12 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions. In the event the Company shall execute a supplemental indenture pursuant to this Section 10.12, the Company shall promptly file with the Trustee an Officer's Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition and any adjustment to be made with respect thereto. 10.13 TRUSTEE'S DISCLAIMER. The Trustee has no duty to determine when an adjustment under this Article X should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officer's Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.10 hereof. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the failure by the Company to comply with any provisions of this Article X. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.12, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officer's Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.12 hereof. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to (A) make any cash payment or issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property upon the surrender of any Security for conversion hereunder, or (B) subject to Article VII, comply with any of the covenants of the Company hereunder. -62- 10.14 RIGHTS DISTRIBUTIONS PURSUANT TO STOCKHOLDERS' RIGHTS PLANS. Upon conversion of any Security or a portion thereof, the Company shall make provision for the Holder thereof to receive, in addition to, and concurrently with the delivery of, the consideration otherwise payable hereunder upon such conversion, the rights described in each and any stockholders' rights plan the Company may have in effect at such time (whether or not the rights have been separated from the Common Stock prior to the time of conversion). In the event that the Company implements a stockholders' rights plan after the date hereof, the Company shall provide that the Holders will receive upon conversion of their Securities, in addition to the consideration otherwise payable hereunder upon such conversion, the rights described therein (whether or not the rights have been separated from the Common Stock prior to the time of conversion). 10.15 INCREASED CONVERSION RATE APPLICABLE TO CERTAIN NOTES SURRENDERED IN CONNECTION WITH MAKE-WHOLE FUNDAMENTAL CHANGES. (A) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with this Article X, at any time from, and including, the date that is fifteen (15) Business Days prior to the date originally announced by the Company as the anticipated effective date of a Make-Whole Fundamental Change (which anticipated effective date the Company shall disclose, in good faith, in the written notice, public announcement and publication referred to in Section 10.15(E)) until, and including, the date that is fifteen (15) Business Days after the actual effective date of such Make-Whole Fundamental Change shall be increased to an amount equal to the Conversion Rate that would, but for this Section 10.15, otherwise apply to such Security pursuant to this Article X, plus an amount equal to the Make-Whole Conversion Rate Adjustment; provided, however, that such increase to the Conversion Rate shall not apply if either: (i) such Make-Whole Fundamental Change constitutes a Public Acquirer Fundamental with respect to which the Company shall have duly made, and given full effect to, an election, pursuant to and in accordance with Section 10.15(F), to make an Acquirer Stock Conversion Right Adjustment; or (ii) such Make-Whole Fundamental Change is announced by the Company but shall not be consummated. The additional consideration payable hereunder on account of any Make-Whole Conversion Rate Adjustment with respect to a Security surrendered for conversion is herein referred to as the "MAKE-WHOLE CONSIDERATION." (B) As used herein, "MAKE-WHOLE CONVERSION RATE ADJUSTMENT" shall mean, with respect to each Make-Whole Fundamental Change and each applicable Security, an amount equal to a fraction whose numerator is the product of the Applicable Increase and the principal amount of such Security to be converted and whose denominator is one thousand dollars ($1,000). As used herein, "APPLICABLE INCREASE" shall mean, with respect to a Make-Whole Fundamental Change, the amount, set forth in the following table, which corresponds to the -63- effective date of such Make-Whole Fundamental Change (the "EFFECTIVE DATE") and the Applicable Price of such Make-Whole Fundamental Change: APPLICABLE INCREASE (per $1,000 principal amount of Securities) EFFECTIVE DATE -------------- JANUARY FEBRUARY FEBRUARY FEBRUARY FEBRUARY FEBRUARY FEBRUARY FEBRUARY APPLICABLE PRICE 25, 2005 1, 2006 1, 2007 1, 2008 1, 2009 1, 2010 1, 2011 1, 2012 - ---------------- -------- ------- ------- ------- ------- ------- ------- ------- $ 8.97....... 37.76 39.53 38.38 36.95 35.06 32.34 28.07 0.00 $ 12.50....... 22.80 23.77 22.55 20.99 18.89 15.86 10.98 0.00 $ 15.00....... 17.01 17.74 16.61 15.17 13.26 10.54 6.36 0.00 $ 17.50....... 13.14 13.73 12.72 11.44 9.76 7.44 4.09 0.00 $ 20.00....... 10.41 10.91 10.02 8.90 7.45 5.51 2.89 0.00 $ 22.50....... 8.39 8.85 8.06 7.09 5.85 4.24 2.20 0.00 $ 25.00....... 6.87 7.29 6.60 5.75 4.70 3.37 1.78 0.00 $ 27.50....... 5.68 6.08 5.47 4.74 3.84 2.74 1.50 0.00 $ 30.00....... 4.73 5.12 4.59 3.95 3.18 2.27 1.29 0.00 $ 32.50....... 3.97 4.35 3.88 3.32 2.67 1.91 1.14 0.00 $ 35.00....... 3.35 3.72 3.31 2.82 2.26 1.62 1.01 0.00 $ 37.50....... 2.84 3.20 2.83 2.41 1.93 1.40 0.91 0.00 $ 40.00....... 2.41 2.76 2.44 2.07 1.65 1.21 0.82 0.00 $ 42.50....... 2.05 2.40 2.11 1.79 1.43 1.06 0.74 0.00 $ 45.00....... 1.74 2.08 1.83 1.55 1.24 0.93 0.68 0.00 $ 47.50....... 1.48 1.82 1.60 1.35 1.08 0.82 0.62 0.00 $ 50.00....... 1.26 1.59 1.39 1.17 0.95 0.73 0.56 0.00 $ 52.50....... 1.07 1.39 1.22 1.03 0.83 0.65 0.52 0.00
provided, however, that: (i) if the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) prices listed in the table above under the column titled "Applicable Price," or if the actual Effective Date of such Make-Whole Fundamental Change is between two dates listed in the table above in the row immediately below the title "Effective Date," then the Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Applicable Increases set forth for such two prices, or for such two dates based on a three hundred and sixty five (365) day year, as applicable; (ii) if the actual Applicable Price of such Make-Whole Fundamental Change is greater than $52.50 per share (subject to adjustment as provided in Section 10.15(B)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental Change is less than $8.97 per share (subject to adjustment as provided in Section 10.15(B)(iii)), then the Applicable Increase shall be equal to zero (0) and this Section 10.15 shall not require the Company to increase the Conversion Rate with respect to such Make-Whole Fundamental Change; (iii) if an event occurs that requires, pursuant to this Article X (other than solely pursuant to this Section 10.15), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above under the column titled "Applicable Price" shall be deemed to be adjusted so that such price, at and after such time, shall be equal to the product of (1) such price as in effect immediately before such adjustment to such price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such -64- adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article X, immediately after such adjustment to the Conversion Rate; (iv) each Applicable Increase amount set forth in the table above shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 10.01 through Section 10.14; and (v) in no event shall the Conversion Rate applicable to any Security be increased pursuant to this Section 10.15 to the extent, but only to the extent, such increase shall not be permitted by the continued listing standards of the Nasdaq National Market; provided, however, that any reduction, pursuant to this Section 10.15(B)(v), in such increase to the Conversion Rate shall be made by the Company in good faith and, to the extent practical, pro rata in accordance with the principal amount of Securities surrendered for conversion in connection with the applicable Make-Whole Fundamental Change. (C) As used herein, "APPLICABLE PRICE" shall have the following meaning with respect to a Make-Whole Fundamental Change: (a) if the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) for the Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the "Applicable Price" with respect to such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of Common Stock in such Make-Whole Fundamental Change; and (b) in all other circumstances, the "Applicable Price" with respect to such Make-Whole Fundamental Change shall be equal to the average of the Closing Sale Prices per share of Common Stock for the five (5) consecutive Trading Days immediately preceding the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the Ex Date of such event occurs, at any time during such five (5) consecutive Trading Days. (D) The Company shall cause any Make-Whole Consideration payable, pursuant to this Section 10.15, with respect to a Security, in connection with the conversion of such Security pursuant to Article X, to be paid, through the Conversion Agent, as soon as practicable, but in no event after the later of (a) the date such Security is surrendered for such conversion and (b) the fifth (5th) Business Day immediately following the Effective Date of the applicable Make-Whole Fundamental Change. The consideration in which the Make-Whole Consideration is payable shall be determined in accordance herewith, including, without limitation, in accordance, to the extent applicable, with Section 10.12. (E) At least fifteen (15) Business Days before the anticipated effective date of each proposed Make-Whole Fundamental Change, the Company shall mail to each Holder, in accordance with Section 11.02, written notice of, and shall publicly announce, through a reputable national newswire service, and publish on the Company's website, the anticipated effective date of such proposed Make-Whole Fundamental Change. Each such notice, -65- announcement and publication shall also state (i) that the Company either (a) has elected, in accordance with Section 10.15(F), to make an Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change in lieu of increasing the Conversion Rate pursuant to Section 10.15(A) or (b) has elected not to make an Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change; and (ii) if the Company has elected not to make such Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change, that, in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Securities must be surrendered in order to be entitled to such increase). No later than the actual Effective Date of each Make-Whole Fundamental Change, the Company shall mail, in accordance with Section 11.02, written notice of, and shall publicly announce, through a reputable national newswire service, and publish on the Company's website, such Effective Date. (F) Notwithstanding anything to the contrary in this Section 10.15, if the Company shall make any mailing, announcement or publication referred to in Section 10.15(E) in respect of a Make-Whole Fundamental Change that shall also constitute a Public Acquirer Fundamental Change, then the Company shall have the right to, in lieu of increasing the Conversion Rate pursuant to Section 10.15(A) in connection with such Make-Whole Fundamental Change, cause the right to convert the Securities in accordance with this Article X to change such that, from and after the effective time of such Public Acquirer Fundamental Change, the right of each Holder of any Security to convert such Security into shares of Common Stock and cash for fractional shares shall be changed into the right to convert such Security solely into shares of Public Acquirer Common Stock applicable to such Public Acquirer Fundamental Change and cash for fractional shares thereof, at an initial Conversion Rate (which shall take effect at such effective time, but which shall thereafter be subject to adjustment in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to this Article X) equal to the Conversion Rate in effect immediately before such effective time multiplied by a fraction whose numerator is the Reference Price and whose denominator is the average of the last reported sale prices per share of such Public Acquirer Common Stock for the five (5) consecutive Trading Days commencing on, and including, the Trading Day immediately after the effective date of such Public Acquirer Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), to account for any event that, assuming such Public Acquirer Common Stock were Common Stock, would require, pursuant hereto, an adjustment to the Conversion Rate to become effective, or any such event whose Ex Date occurs, at any time during such five (5) consecutive Trading Days. Any such change in the right to convert the Securities in accordance with this Section 10.15(F) is herein referred to as an "ACQUIRER STOCK CONVERSION RIGHT ADJUSTMENT." If the Company shall have elected, in accordance with this Section 10.15(F), to make an Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer Fundamental Change, then: (i) the Company shall cause there to be executed and delivered to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee, which -66- supplemental indenture shall (a) give due effect to such election in accordance with this Section 10.15(F), including, without limitation, evidencing a binding and enforceable obligation of the issuer of the applicable Public Acquirer Common Stock to satisfy the right of Holders to convert Securities in accordance with this Article X and this Section 10.15(F); (b) be executed by, without limitation, such issuer; (c) contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors in good faith shall reasonably determine (which determination shall be described in a Board Resolution); and (d) be in full force and effect no later than the effective time of such Public Acquirer Fundamental Change; (ii) the Company shall promptly file with the Trustee an Officer's Certificate briefly stating the reasons for such supplemental indenture, the nature of the change in the conversion right pursuant to such Acquirer Stock Conversion Right Adjustment and the Conversion Rate as adjusted therefor; (iii) the provisions of Section 10.12 shall not apply to such Public Acquirer Fundamental Change, provided such Public Acquirer Fundamental Change shall have been duly given effect in accordance with this Section 10.15(F); and (iv) such election shall be irrevocable with respect to such Public Acquirer Fundamental Change and shall be deemed to have been made at the time the Company shall, with respect to such Public Acquirer Fundamental Change, mail the first notice, or make the first public announcement or publication, whichever shall occur earlier, referred to in Section 10.15(E) (it being understood that the Company shall discharge its obligations hereunder in good faith in determining whether an announced transaction and a completed transaction are deemed, for purposes of this clause (iv), to be the same Public Acquirer Fundamental Change despite differences in the announced terms and the terms as such transaction was consummated); provided, however, that the Company shall not be required to give effect to such election to make an Acquirer Stock Conversion Right Adjustment with respect to such Public Acquirer Fundamental Change if such Public Acquirer Fundamental Change is not consummated. For avoidance of doubt, any change, pursuant to this Section 10.15(F), in the right of Holders to convert Securities shall apply to all Holders. As used herein, "REFERENCE PRICE" shall have the following meaning with respect to a Public Acquirer Fundamental Change: (a) if such Public Acquirer Fundamental Change shall be a share exchange, consolidation, merger or binding share exchange pursuant to which the Common Stock is converted into cash, securities or other property, then the "Reference Price" with respect to such Public Acquirer Fundamental Change shall mean the fair market value (as determined in good faith by the Board of Directors, which determination shall be described in a Board Resolution), as of the effective time of such Public Acquirer Fundamental Change, of such cash, securities and other property paid or payable pursuant to such Public Acquirer Fundamental Change per share of Common Stock; and (b) in all other circumstances, the "Reference Price" with respect to such Public Acquirer Fundamental Change shall mean the average of the Closing Sale Prices per share of Common Stock for the five (5) consecutive Trading Days immediately -67- preceding, and excluding, the effective date of such Public Acquirer Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the Ex Date of such event occurs, at any time during such five (5) consecutive Trading Days. (G) For avoidance of doubt, the provisions of this Section 10.15 shall not affect or diminish the Company's obligations, if any, pursuant to Article V with respect to a Public Acquirer Fundamental Change or Make-Whole Fundamental Change. (H) Nothing in this Section 10.15 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.06 in respect of a Make-Whole Fundamental Change or a Public Acquirer Fundamental Change. XI. MISCELLANEOUS 11.01 TRUST INDENTURE ACT CONTROLS.

The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Securities are general unsecured senior obligations of the Company limited to $50,000,000 aggregate principal amount A-3 ($60,000,000 if the Initial Purchasers have elected to exercise in full the Option to purchase up to an additional $10,000,000 aggregate principal amount of the Securities), except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or stolen Securities). Terms used herein without definition and which are defined in the Indenture have the meanings assigned to them in the Indenture. 6. OPTIONAL REDEMPTION. The Company shall have the right, at the Company's option, at any time, and from time to time, on a Redemption Date on or after February 1, 2012, to redeem all or any part of the Securities at a price payable in cash equal to one hundred percent (100%) of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date. Upon surrender to the Paying Agent of a Security subject to Redemption, such Security shall be paid, to the Holder surrendering such Security, at the Redemption Price plus accrued and unpaid interest to, but excluding, the Redemption Date, unless the Redemption Date is an interest payment date, in which case such accrued and unpaid interest will instead be paid on such interest payment date to the Holder of record of such Security at the close of business on the record date for such interest payment. The Company will make at least fourteen (14) semi-annual interest payments with respect to the Securities prior to redeeming any Securities under this paragraph 6. If the Paying Agent (other than the Company) holds on a Redemption Date money sufficient to pay the aggregate Redemption Price with respect to all Securities to be redeemed, plus accrued and unpaid interest, if any, payable as provided in the Indenture upon Redemption, then (unless there shall be a Default in the payment of such aggregate Redemption Price or of such accrued and unpaid interest) on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Redemption Price, plus such accrued and unpaid interest, in accordance with the Indenture. 7. NOTICE OF REDEMPTION. Notice of Redemption will be mailed at least thirty (30) days but not more than sixty (60) days before the Redemption Date to each Holder of Securities to be redeemed at its address appearing in the security register. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount. 8. PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER. Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, the Securities held by such Holder on February 1, 2012, February 1, 2015 and February 1, 2020 (each, an "OPTION PURCHASE DATE") at an Option Purchase Price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable Option Purchase Date, upon delivery of a Purchase Notice containing the information set forth in the A-4 Indenture, at any time from 9:00 a.m., New York City time, on the date that is twenty (20) Business Days prior to the applicable Option Purchase Date until 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the applicable Option Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture. Holders have the right to withdraw any Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. If the Paying Agent (other than the Company) holds on an Option Purchase Date money sufficient to pay the aggregate Option Purchase Price with respect to all Securities to be purchased upon Purchase at Holder's Option, plus accrued and unpaid interest, if any, payable as provided in the Indenture upon Purchase at Holder's Option, then (unless there shall be a Default in the payment of such aggregate Option Purchase Price or of such accrued and unpaid interest) on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Option Purchase Price, plus such accrued and unpaid interest, in accordance with the Indenture. 9. REPURCHASE AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE. Subject to the terms and conditions of the Indenture, in the event of a Fundamental Change, each Holder of the Securities shall have the right, at the Holder's option, to require the Company to repurchase such Holder's Securities including any portion thereof which is $1,000 in principal amount or any integral multiple thereof on a date selected by the Company (the "FUNDAMENTAL CHANGE REPURCHASE DATE"), which date is no later than thirty (30) days after the date on which notice of such Fundamental Change is mailed in accordance with the Indenture, at a price payable in cash equal to one hundred percent (100%) of the principal amount of such Security, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date. Within thirty (30) days after the occurrence of the Fundamental Change, the Company must mail, or cause to be mailed, notice of the occurrence of such Fundamental Change to each Holder at the address of such Holder appearing in the register of the Registrar. Such notice shall include, among other things, a description of the procedure which a Holder must follow to exercise the Fundamental Change Repurchase Right. To exercise the Fundamental Change Repurchase Right, a Holder of Securities must, in accordance with the provisions of the Indenture, (i) deliver, no later than 5:00 p.m., New York City time, on the third (3rd) Business Day immediately preceding the Fundamental Change Repurchase Date, a Purchase Notice to the Company (if it is acting as its own Paying Agent) or to the Paying Agent; and (ii) deliver, at any time after the delivery of such Purchase Notice, the Securities with respect to which the Holder is exercising its Fundamental Change Repurchase Right (together with all necessary endorsements). If the Securities delivered in connection with a Holder's exercise of its Fundamental Change Repurchase Right are held in book-entry form through the Depositary, then such Purchase Notice must comply with applicable procedures of the Depositary. 10. CONVERSION. A-5 Subject to earlier Redemption, Purchase at Holder's Option or Repurchase Upon Fundamental Change, Holders may surrender Securities in integral multiples of $1,000 principal amount for conversion into shares of Common Stock in accordance with Article X of the Indenture at any time prior to stated maturity. To convert a Security, a Holder must (1) complete and sign the Conversion Notice, with appropriate signature guarantee, on the back of the Security, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (4) pay the amount of interest, if any, the Holder must pay in accordance with the Indenture and (5) pay any tax or duty if required pursuant to the Indenture. A Holder may convert a portion of a Security if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. The initial Conversion Rate is 92.9023 shares of Common Stock per $1,000 principal amount of Securities (which results in an effective initial Conversion Price of approximately $10.76 per share) subject to adjustment in the event of certain circumstances as specified in the Indenture. The Company will deliver a check in lieu of any fractional share. Except as other otherwise provided herein or in the Indenture, on conversion, no payment or adjustment for any unpaid and accrued interest on, or additional interest with respect to, the Securities will be made. If a Holder surrenders a Security for conversion after the close of business on the record date for the payment of an installment of interest and prior to the related interest payment date, such Security, when surrendered for conversion, must be accompanied by cash payment of an amount equal to the interest thereon which the registered Holder at the close of business on such record date is to receive (other than overdue interest, if any, that has accrued on such Security), unless such Security has been called for Redemption as described in the Indenture. The Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with the Securities and Article X of the Indenture, at any time from, and including, the date that is fifteen (15) Business Days prior to the date originally announced by the Company as the anticipated effective date of a Make-Whole Fundamental Change until, and including, the date that is fifteen (15) Business Days after the actual effective date of such Make-Whole Fundamental Change shall be increased to an amount equal to the Conversion Rate that would, but for Section 10.15 of the Indenture, otherwise apply to such Security pursuant to Article X of the Indenture, plus an amount equal to the Make-Whole Conversion Rate Adjustment; provided, however, that such increase to the Conversion Rate shall not apply if (i) such Make-Whole Fundamental Change constitutes a Public Acquirer Fundamental with respect to which the Company shall have duly made, and given full effect to, an election, pursuant to and in accordance with Section 10.15(F) of the Indenture, to make an Acquirer Stock Conversion Right Adjustment; or (ii) such Make-Whole Fundamental Change is announced by the Company but shall not be consummated. Any shares of Common Stock that are issued upon conversion of a Security shall bear the Private Placement Legend until after the second anniversary of the later of the Issue Date and the last date on which the Company or any Affiliate was the owner of such shares or the Security (or any predecessor security) from which such shares were converted (or such shorter period of time as permitted by Rule 144(k) under the Securities Act or any successor A-6 provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as set forth in an Opinion of Counsel, unless otherwise agreed by the Company and the Holder thereof). 11. DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or similar governmental charge that may be imposed in connection with certain transfers or exchanges. The Company or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security (i) during a period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of the Securities selected for Redemption under Section 3.04 of the Indenture and ending at the close of business on the day of such mailing or (ii) for a period of fifteen (15) days before selecting, pursuant to Section 3.03 of the Indenture, Securities to be redeemed or (iii) that has been selected for Redemption or for which a Purchase Notice has been delivered, and not withdrawn, in accordance with the Indenture, except the unredeemed or unrepurchased portion of Securities being redeemed or repurchased in part. 12. PERSONS DEEMED OWNERS. The registered Holder of a Security may be treated as the owner of such Security for all purposes. 13. MERGER OR CONSOLIDATION. Except as provided in the Indenture, the Company shall not consolidate with, or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the property or assets of the Company to, another person, whether in a single transaction or series of related transactions, unless (A) either (i) such transaction or series of transactions shall be a merger or consolidation where the Company shall be the surviving corporation; or (ii) the surviving, resulting or transferee person both (a) is a corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia; and (b) assumes by supplemental indenture all the obligations of the Company under the Securities and the Indenture; and (B) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall exist. 14. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities, and certain existing Defaults or Events of Default may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. In accordance with the terms of the Indenture, the Company, with the consent of the Trustee, may amend or supplement this Indenture or the Securities without notice to or the consent of any Securityholder: (i) to comply with Sections 5.01 and 10.12 of the Indenture and, in accordance with Section 10.15(F) of the Indenture, to give effect to an election, pursuant to such Section 10.15(F), by the Company to make an Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer Fundamental Change; (ii) to make any changes or modifications to the Indenture necessary in connection with the registration of the Securities under the Securities Act A-7 pursuant to the Registration Rights Agreement or the qualification of the Indenture under the TIA; (iii) to secure the obligations of the Company in respect of the Securities; (iv) to add to the covenants of the Company described in the Indenture for the benefit of Securityholders or to surrender any right or power conferred upon the Company; (v) to make provisions with respect to adjustments to the Conversion Rate as required by the Indenture or to increase the Conversion Rate in accordance with the Indenture; (vi) to add additional events which shall constitute an Event of Default under the Indenture; and (vii) to provide for a successor Trustee in accordance with the Indenture. In addition, the Company and the Trustee may enter into a supplemental indenture without the consent of Holders of the Securities to cure any ambiguity, defect, omission or inconsistency in the Indenture in a manner that does not individually or in the aggregate adversely affect the rights of any Holder in any material respect. 15. DEFAULTS AND REMEDIES. Subject to the provisions of the Indenture, an "EVENT OF DEFAULT" occurs if (i) the Company defaults in the payment of the principal of, or premium, if any, on, any Security when the same becomes due and payable, whether at maturity, upon Redemption, on an Option Purchase Date with respect to a Purchase at Holder's Option, on a Fundamental Change Repurchase Date with respect to a Repurchase Upon Fundamental Change or otherwise; (ii) the Company defaults in the payment of an installment of interest or additional interest, on any Security when due, if such failure continues for thirty (30) days after the date when due; (iii) the Company fails to satisfy its conversion obligations upon exercise of a Holder's conversion rights pursuant to the Indenture; (iv) the Company fails to timely provide a Fundamental Change Notice, or an Option Purchase Notice, as required by the provisions of the Indenture; (v) the Company fails to comply with any other term, covenant or agreement set forth in the Securities or the Indenture and such failure continues for the period, and after the notice, specified in the Indenture; (vi) the Company or any of its Subsidiaries defaults in the payment when due, after the expiration of any applicable grace period, of principal of, or premium, if any, or interest on, Indebtedness of the Company or any Subsidiary for money borrowed, in the aggregate principal amount then outstanding of ten million dollars ($10,000,000) or more, or the acceleration of Indebtedness of the Company or any of its Subsidiaries for money borrowed in such aggregate principal amount or more so that it becomes due and payable prior to the date on which it would otherwise become due and payable and such default is not cured or waived, or such acceleration is not rescinded, within sixty (60) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five percent (25%) in the aggregate principal amount of the Securities then outstanding, each in accordance with the Indenture; or (vii) there occur certain events of bankruptcy or insolvency involving the Company or any of its Significant Subsidiaries or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company. If an Event of Default (excluding an Event of Default specified in Section 6.01(vii) or (viii) of the Indenture with respect to the Company (but including an Event of Default specified in Section 6.01(vii) or (viii) of the Indenture solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by notice to the Company or the Holders of at least twenty five percent (25%) in principal amount of the Securities then outstanding by notice to the Company and the Trustee may declare the Securities to be due and payable. Upon such declaration, the principal of, and any premium and accrued and unpaid interest (including any additional interest) on, all Securities shall be due and A-8 payable immediately. If an Event of Default specified in Section 6.01(vii) or (viii) of the Indenture with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(vii) or (viii) of the Indenture solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and premium and accrued and unpaid interest (including any additional interest) on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if (A) the rescission would not conflict with any governmental or court order or decree, (B) all existing Events of Default, except the nonpayment of principal, premium or interest that has become due solely because of the acceleration, have been cured or waived and (C) all amounts due to the Trustee under Section 7.07 of the Indenture have been paid. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity reasonably satisfactory to it ; provided, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of the Indenture, or as to which a Responsible Officer of the Trustee shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within thirty (30) days after the Trustee has received such notice or after such Responsible Officer shall have acquired such actual knowledge, whichever is earlier, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment of any amounts due with respect to any Security, the Trustee may withhold such notice if, and so long as it in good faith determines that, withholding such notice is in the best interests of Holders. The Company must deliver to the Trustee an annual compliance certificate. 16. REGISTRATION RIGHTS. The Holders are entitled to registration rights as set forth in the Registration Rights Agreement. The Holders shall be entitled to receive additional interest in certain circumstances, all as set forth in the Registration Rights Agreement. 17. TRUSTEE DEALINGS WITH THE COMPANY.

NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee or stockholder, as such, of the Company shall have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by A-9 reason of, such obligations or their creation.
