Negative Covenants

So long as any of the Notes remain outstanding, the Company and each Company Indenture Party covenants and agrees that, neither the Company nor any other Company Indenture Party will do, nor will the Company or any other Company Indenture Party permit any of their Subsidiaries (other than the Excluded Subsidiaries unless expressly specified otherwise below) to do any of the following:

Section 5.01. Indebtedness.

(a) create, incur, assume, suffer to exist, guarantee, or otherwise become or remain, directly or indirectly, liable with respect to any Indebtedness, except for Permitted Indebtedness.

(b) incur any Permitted Indebtedness that is contractually subordinated in right of payment to any other Indebtedness of a Company Indenture Party (other than the ABL Loan Obligations and Term Loan Obligations) unless such Indebtedness is also contractually subordinated in right of payment to the Obligations on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of being secured on a junior Lien basis.

For purposes of determining compliance with Section  5.01 , in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness, or is entitled to be incurred pursuant to Section  5.01(a) , the Company will be permitted to classify and divide such item of Indebtedness on the date of its incurrence, and later reclassify and redivide all or a portion of such item of Indebtedness among any one or more of such clauses and/or Section  5.01(a) , in any manner that complies with Section  5.01 . Indebtedness under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (a) of the definition of Permitted Indebtedness. For purposes of determining compliance with any U.S. dollar denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that any Company Indenture Party may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. In determining the amount of Indebtedness outstanding, the outstanding amount of any particular Indebtedness of any Person shall be counted only once.

Section 5.02. Liens . Create, incur, assume, or suffer to exist, directly or indirectly, any (a) Lien on or with respect to any of its assets, of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, except for Permitted Liens; (b) Lien of any subcontractor of any Company Indenture Party on the assets of any customer of any Company Indenture Party, unless, and to the extent, such subcontractor Lien is discharged, satisfied, vacated, bonded, or stayed within five (5) Business Days thereof; (c) Lien on or with respect to any assets of any Company Indenture Party or any of its Subsidiaries (other than Excluded Subsidiaries), of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, in each case, for the benefit of any Excluded Subsidiary or (d) Lien on or with respect to any Excluded Subsidiary’s assets, of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, to secure Indebtedness for borrowed money other than the Closing Date Acquisition Obligations and the Liens described in the clause (f) of “Permitted Liens” as defined in the Closing Date Loan Agreement as in effect on the date hereof.

For purposes of satisfying the standard set forth in Section  5.12(a)(ii) above, if the transaction (or series of related transactions) with an Affiliate is valued at or in excess of $5 million, a majority of the independent members of the Board of Directors of the applicable Company Indenture Party, must conclude in good faith (and, cause an Officers’ Certificate to that effect to be delivered Trustee) that such transaction was undertaken upon fair and reasonable terms, no less favorable (to Company or such Subsidiary, as applicable) than would have been obtained in a comparable arm’s length transaction with a non-Affiliate (or, if no such comparable transaction is available, otherwise fair to the Company or such Subsidiary).

Section 5.13. Use of Proceeds . Use the proceeds of the Notes hereunder for any purpose other than (a) to pay all of the outstanding Closing Date Acquisition Obligations, (b) to repay some or all of the outstanding ABL Loan Obligations, (c) [Intentionally omitted]; (d) to pay fees, costs, and expenses of Company, incurred in connection with this Indenture, the Indenture Documents, and the transactions contemplated hereby and thereby, and (e) consistent with the terms and conditions hereof, for general corporate and working capital purposes .

ARTICLE 6

Collateral and Security

Section 6.01. Security Interest. The Obligations will be secured by a perfected Lien on the Collateral, subject to the Permitted Liens and the Intercreditor Agreement, as provided in the Security Documents. The Collateral will also secure certain of the Company’s and the Guarantors’ existing obligations under the Term Documents and the ABL Documents, subject to the Intercreditor Agreement. Under the terms of the Intercreditor Agreement, the proceeds of any collection, sale, disposition or other realization of Collateral received in connection with the exercise of remedies (including distributions of cash, securities or other property on account of the value of the Collateral in a bankruptcy, insolvency, reorganization or similar proceedings) will be applied in the order of priority set forth in the Intercreditor Agreement.

Section 6.02. Security Documents. In order to secure the Obligations, the Company Indenture Parties have entered into and delivered to the Collateral Trustee the Security Agreement and the other Security Documents, in each case, to which it is a party, to create the Liens on the Collateral securing their respective Obligations. In the event of a conflict between the terms of this Indenture and the Security Documents in regards to the Collateral, the Security Documents shall control. The Company will take, and will cause its Subsidiaries to take any and all actions (including those that may be requested by the Trustee or the Collateral Trustee) reasonably required to cause the Security Documents to create and maintain, as security for the obligations of the Company hereunder, a valid and enforceable perfected Lien in and on all the Collateral, in favor of the Collateral Trustee for the benefit of the Holders, the Trustee and the Collateral Trustee, subject to Permitted Liens and the Intercreditor Agreement .

68

Section 6.03. Authorization of Actions to Be Taken.

(a) Each Holder of Notes, by its acceptance thereof, hereby designates and appoints the Collateral Trustee as its agent under this Indenture and the Security Documents and each Holder by acceptance of the Notes consents and agrees to the terms of each Security Document, as originally in effect and as amended, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Collateral Trustee to enter into the Security Documents, and irrevocably authorizes and empowers the Collateral Trustee to perform its obligations and duties, exercise its rights and powers and take any action permitted or required thereunder that are expressly delegated to the Collateral Trustee by the terms of this Indenture and the Security Documents. The Collateral Trustee shall hold (directly or through any agent) and is directed by each Holder to so hold, and shall be entitled to enforce on behalf of the Holders all Liens on the Collateral created by the Security Documents for their benefit.

(b) Subject to the provisions of the applicable Security Documents and the Intercreditor Agreement, the Trustee and each Holder, by acceptance of any Notes, agrees that (x) the Collateral Trustee may, in its sole discretion and without the consent of the Trustee or the Holders, take all actions it deems necessary or appropriate in order to (i) preserve the Collateral or rights under the Security Documents and (ii) collect and receive any and all amounts payable in respect of the Obligations of the Company and the Guarantors hereunder and under the Indenture Documents and (y) the Collateral Trustee shall have power to institute and to maintain such suits and proceedings as it may deem expedient to protect or enforce the Liens securing the Obligations and/or to prevent any impairment of the Collateral by any act that may be unlawful or in violation of the Indenture Documents, and such suits and proceedings as the Collateral Trustee may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Collateral Trustee, the Holders or the Trustee). Notwithstanding the foregoing, the Collateral Trustee may, at the expense of the Company, request the direction of the Holders with respect to any such actions and upon receipt of the written consent of the Required Holders, shall take such actions; provided that all actions so taken shall, at all times, be in conformity with the requirements of the Intercreditor Agreement, if applicable. Until the Notes and the other Obligations are discharged in full or are otherwise no longer outstanding, all remedies and Enforcement Actions in respect of the Collateral and any foreclosure actions in respect of any Liens on the Collateral, and all actions, undertakings or consents by the Collateral Trustee in respect of the Collateral, in each case, shall be undertaken solely at the instruction of the Required Holders and subject to the Intercreditor Agreement.

69

Section 6.04. Release of Collateral .

(a) The Liens securing the Obligations on the applicable Collateral shall be automatically terminated and released without further action by any party (other than satisfaction of any requirements in the Security Documents, if any), in whole or in part: (i) upon any Disposition of any portion of Collateral in accordance with a Disposition permitted under the terms of any Indenture Document (other than a Disposition to a Company Indenture Party); (ii) upon discharge of this Indenture and the other Indenture Documents in accordance with Article 3 ; (iii) at the direction of the Supermajority Holders; or (iv) if the Collateral is owned by a Guarantor, upon release of such Guarantor from the Guaranteed Obligations in accordance with the provisions hereof.

(b) Without the necessity of any consent of or notice to the Trustee or any Holder of the Notes, any Company Indenture Party may request and instruct the Collateral Trustee to, on behalf of each Holder of Notes, (i) execute and deliver to any Company Indenture Party, as the case may be, for the benefit of any Person, such release documents as may be reasonably requested, of all Liens held by the Collateral Trustee in any Collateral securing the Obligations, and (ii) deliver any such assets in the possession of the Collateral Trustee to any Company Indenture Party, as the case may be; and Collateral Trustee shall promptly take such actions provided that any such release complies with and is expressly permitted in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents and is accompanied by an Officers’ Certificate and Opinion of Counsel.

(c) The release of any Collateral from the Liens securing the Obligations or the release of, in whole or in part, the Liens securing the Obligations created by any of the Security Document will not be deemed to impair the Liens securing the Obligations in contravention of the provisions hereof if and to the extent the Collateral or the Liens securing the Obligations are released pursuant to the terms of this Indenture and the applicable Security Documents. Each of the Holders of the Notes acknowledges that a release of Collateral or Liens securing the Obligations strictly in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents will not be deemed for any purpose to be an impairment of the Security Documents or otherwise contrary to the terms of this Indenture.

Section 6.05. Application of Proceeds of Collateral.

(a) Upon any realization upon the Collateral from the exercise of any rights or remedies under any Security Document or any other agreement with any Company Indenture Party which secures any of the Obligations, the proceeds thereof shall be applied in accordance with Section  9.05 of this Indenture.

70

Section 6.06. Collateral Trustee.

(a) Subject to the provisions of Section  10.01 , neither the Trustee, nor the Collateral Trustee nor any of their respective officers, directors, employees, attorneys or agents shall be responsible or liable (i) for the legality, enforceability, effectiveness or sufficiency of the Security Documents, for the creation, perfection, priority, sufficiency, maintenance, renewal or protection of any Lien, or for any defect or deficiency as to any such matters, or (ii) for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or Security Documents or any delay in doing so; except, in the case of the Collateral Trustee, to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct (as determined by a final order of a court of competent jurisdiction that is not subject to appeal) on the part of the Collateral Trustee, (iii) for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral or (iv) for the legality, enforceability, effectiveness or sufficiency of the Intercreditor Agreement, Intercompany Subordination Agreement, or any subordination agreement or other similar agreement entered into in connection with this Indenture.

(b) The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture, including, without limitation, its right to be indemnified and compensated and all other rights, privileges, protections, immunities and benefits set forth in Article 10 , are extended to the Collateral Trustee, and its agents, receivers and attorneys, and shall be enforceable by, the Collateral Trustee, as if fully set forth in this Section  6.06 with respect to the Collateral Trustee, except that the Collateral Trustee shall only be liable for (and shall be indemnified and held harmless to the extent such Losses do not constitute) its gross negligence, bad faith or willful misconduct (as determined by a final order of a court of competent jurisdiction that is not subject to appeal). In acting under any Security Document or the Intercreditor Agreement, the Collateral Trustee shall enjoy the rights, privileges, protections, immunities and benefits that are extended to the Collateral Trustee hereunder.

(c) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. In addition, the Collateral Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral, unless specifically requested by the Required Holders. If, at the direction of the Required Holders, the Trustee or Collateral Trustee files or records any Security Documents or any related UCC financing statement or other similar documents, such filing or recording by the Trustee or Collateral Trustee at the direction of the Required Holders shall be deemed done by Trustee or Collateral Trustee without representation or warranty by the Trustee or the Collateral Trustee (and the Trustee and the Collateral Trustee disclaim any representation or warranty as to the validity, effectiveness, priority, perfection or otherwise). The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords property held by it as a collateral agent or any similar arrangement, and the Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in good faith.

71

(d) The Collateral Trustee shall not have any duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or any Indenture Document by the Company or any Company Indenture Party or any other Person that is a party thereto or bound thereby.

(e) The Collateral Trustee shall not be required to acquire title to an asset for any reason and shall not be required to carry out any fiduciary or trust obligation for the benefit of another. The Collateral Trustee is not a fiduciary and shall not be deemed to have assumed any fiduciary obligation. If the Collateral Trustee in its sole discretion believes that any obligation to take or omit to take any action may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment.

(f) The Collateral Trustee may resign or be replaced in accordance with the procedures set forth in Section  10.09 hereof, except that references to the Trustee in such section shall be deemed to be references to the Collateral Trustee for this purpose. If the Collateral Trustee consolidates, 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 will be the successor Collateral Trustee.

(g) At all times when the Trustee is not itself the Collateral Trustee, the Company shall deliver to the Trustee copies of all Security Documents delivered to the Collateral Trustee and copies of all documents delivered to the Collateral Trustee pursuant to the Security Documents.

Section 6.07. Trust Indenture Act Requirements; Opinion of Counsel; Certificates of the Company. The Company Indenture Parties shall furnish to the Collateral Trustee and the Trustee at least thirty (30) days prior to each anniversary of the Issue Date, an Opinion of Counsel, dated as of such date, stating that, in the opinion of such counsel, (A) action has been taken with respect to the filing of record by each applicable Company Indenture Party all UCC financing statements, continuation statements or amendments as is necessary to maintain the Liens on the portion of the Collateral securing the Obligations for which perfection of such Lien may be accomplished under the Code by filing a UCC financing statement, continuation statement or financing statement amendment in the office of the Secretary of State of the State of Delaware (or such other applicable filing office) and the payment of all applicable filing fees and (B) based on relevant laws as in

72

effect on the date of such Opinion of Counsel, continuation statements and financing statement amendments have been filed of record that are necessary as of such date and during the succeeding 18 months fully to preserve and perfect the Liens on the portion of the Collateral securing the Obligations for which perfection of such Lien may be accomplished under the Code by filing a UCC financing statement, continuation statement or financing statement amendment in the office of the Secretary of State of the State of Delaware (or such other applicable filing office) and the payment of all applicable filing fees and such Opinion of Counsel may contain customary qualifications and exceptions and may rely on an Officers’ Certificate (as to factual matters only); provided that if there is a required filing of a continuation statement or other instrument within such 18 month period and such continuation statement or amendment is not effective if filed at the time of the Opinion of Counsel, such Opinion of Counsel may so state that and in that case the Company Indenture Parties shall cause a continuation statement or amendment to be timely filed so as to maintain such Liens and security interests securing the Obligations.

ARTICLE 7

Guarantees

Section 7.01. Subsidiary Guarantees.

(a) Subject to this Article 7 , each of the Guarantors hereby, jointly and severally, unconditionally guarantees, on a senior secured basis, as primary obligors and not as a surety, to each Holder (and its successors and assigns) of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes, the Indenture Documents and/or the Obligations of the Company, that:

(i) the principal of and interest on the Notes shall be promptly paid in full or performed when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest (including but not limited to any interest, fees, costs or charges that would accrue but for the provisions of Bankruptcy Code after any Insolvency Proceeding), on the Notes, if any, if lawful, and all other Obligations of the Company and the Company Indenture Parties to the Holders, the Trustee or to the Collateral Trustee under this Indenture, the other Indenture Documents and the Note Purchase Agreement shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof;

(b) Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Company.

73

(c) The Guarantors hereby agree that their obligations hereunder shall be absolute, irrevocable and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of the Notes, this Indenture, the Indenture Documents or any other agreement or instrument referred to herein or therein, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a surety or Guarantor, all to the fullest extent permitted by law. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantors hereunder which remain absolute, irrevocable and unconditional under any and all circumstances as described above, to the fullest extent permitted by law:

(i) at any time or from time to time, without notice to the Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of this Indenture or the Notes, if any, or any other agreement or instrument referred to herein or therein shall be done or omitted;

(iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be amended in any respect, or any right under the Indenture, Notes, or any other agreement or instrument referred to herein or therein shall be amended or waived in any respect or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with;

(iv) any Lien or security interest granted to, or in favor of any Holder, the Collateral Trustee or the Trustee as security for any of the Guaranteed Obligations shall fail to be perfected; or

(v) the release of any other Guarantor.

(d) Each Guarantor further, to the fullest extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

74

(e) Until terminated in accordance with Section  7.03 , each Subsidiary Guarantee shall, to the fullest extent permitted by law, remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation, reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Subsidiary Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(f) Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section  9.02 hereof (and shall be deemed to have become automatically due and payable in the circumstances in said Section  9.02 ) for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such obligations as provided in Section  9.02 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

(g) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee, the Collateral Trustee or any Holder in enforcing any rights under the Indenture Documents and the Note Purchase Agreement.

(h) Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any Guarantor pursuant to the provisions of this Section  7.01 ; provided that, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture, the Notes or the Indenture Documents shall have been paid in full in cash.

(i) Each payment to be made by a Guarantor in respect of its Subsidiary Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

(b) Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section  7.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Subsidiary Guarantee on the Notes. If an officer whose signature is on this Indenture (or a supplemental indenture) no longer holds that office at the time the Trustee authenticates a Note, the Subsidiary Guarantee of such Guarantor shall be valid nevertheless.

(c) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

Section 7.03. Releases of Subsidiary Guarantees.

(a) The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released: (1) in connection with (x) any Disposition (including by way of merger or consolidation) of the Capital Stock of such Guarantor (or the Capital Stock of the direct parent of such Guarantor) to a Person that is not (either before or after giving effect to such transaction) a Company Indenture Party, to the extent such sale is permitted hereunder or to the extent such Capital Stock constitutes Excluded Property or (y) any sale or other Disposition of all or substantially all of the properties or assets of that Guarantor, by way of merger, consolidation or otherwise solely to the extent that such sale or other Disposition is permitted pursuant to Section  14.02 ; (2) the liquidation or dissolution of such Guarantor; provided that no Event of Default occurs as a result thereof or has occurred or is continuing; (3) upon satisfaction and discharge of this Indenture in accordance with Article 3 or (4) upon payment of the Obligations in full in immediately available funds, provided, in each case that the transaction is permitted under this Indenture and is otherwise carried out pursuant to, and in accordance with, all other applicable provisions of this Indenture.

(b) Upon delivery by the Company to the Trustee of an Officers’ Certificate and Opinion of Counsel to the effect that any of the conditions described in the foregoing clauses (1), (2), or (3) of Section  7.03(a) has occurred and the conditions precedent to such transactions provided for in this Indenture have been complied with, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest, premium, and Additional Interest, if any, on, the Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 7 .

Additional Interest payable pursuant to this Section  9.03 shall be in addition to, not in lieu of, any liquidated damages payable pursuant to the Registration Rights Agreement. If the Company so elects, it shall advise Trustee in writing and such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 181st day), the Notes shall be immediately subject to acceleration as provided in Section  9.02 . The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section  4.05 or 4.06(b) . In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section  9.03 or the Company elected to make such payment but fails to pay the Additional Interest when due and such failure becomes an Event of Default, the Notes shall be subject to acceleration as provided in Section  9.02.

Upon the failure to timely give such notice, the Notes shall be subject to acceleration as provided in Section  9.02 .

Section 9.04. Payments of Notes on Default; Suit Therefor.

(a) If an Event of Default described in Section  9.01(a) , (b) or (c)  shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal (including the Fundamental Change Repurchase Price, if applicable), the Redemption Price (if applicable) and interest, if any, with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on any overdue principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable), at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee and the Collateral Trustee under Section  6.06 and Section  10.06 .

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

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

84

(f) In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section  9.09 or any rescission and annulment pursuant to Section  9.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

ARTICLE 17

Conversion of Notes

Section 17.01. Conversion Privilege. Subject to and upon compliance with the provisions of this Article 17 , each Holder of a Note shall have the right, at such Holder’s option, at any time prior to the close of business on the second Business Day immediately preceding the Maturity Date, to convert all or a portion of such Note, at an initial conversion rate of 173.91304 shares of Common Stock (subject to adjustment as provided in this Article 17 and in the Registration Rights Agreement, the “ Conversion Rate ”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section  17.02 , the “ Conversion Obligation ”) into shares of Common Stock or, to the extent set forth in the Note Purchase Agreement, warrants to purchase shares of Common Stock (“ Warrants ”). The Conversion Rate shall be increased by 3.00% for each $1,000 principal amount of Notes converted or redeemed (as applicable) at a time when a Registration Default (as defined under the Registration Rights Agreement) has occurred and is continuing; provided, however, that (i) the foregoing adjustment shall not be applied more than once to the same $1,000 principal amount of Notes and (ii) if a Registration Default (as defined under the Registration Rights Agreement) occurs after a Holder has converted its Notes into shares of Common Stock, such Holder shall not be entitled to any such additional compensation with respect to such Common Stock.

Section 17.02. Conversion Procedure; Settlement Method .

(a) Each Note shall be convertible at the office of the Conversion Agent.

(b) Before any Holder of a Note shall be entitled to convert a Note as set forth in this Article 17 , such Holder shall:

(i) in the case of a Global Note, (1) comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section  17.02(h) and (2) if required, pay all transfer or similar Taxes, if any, as set forth in Section  17.02(f) ; and

(ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “ Notice of Conversion ”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) with respect to any Permitted Holder, complete, manually sign and deliver the warrant election form attached as Exhibit A to the Note Purchase Agreement (failure to deliver such election shall be deemed to constitute an election to receive shares of Common Stock), (3) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (4) if required, pay all transfer or similar Taxes, if any, as set forth in Section  17.02(f) and (5) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section  17.02(h) .

107

The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 17 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section  18.03 . If a Holder submits its Notes for required repurchase upon a Fundamental Change, the Holder’s right to withdraw the Fundamental Change Repurchase Notice and convert the Notes that are subject to repurchase will terminate at the close of business on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date.

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered.

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “ Conversion Date ”) that the Holder has complied with the requirements set forth in Section  17.02(b) above. Except as set forth in Section  17.03(b) and Section  17.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation (A) in the case of Physical Settlement, on the second Business Day immediately following the relevant Conversion Date, unless such Conversion Date occurs on or after the Regular Record Date immediately preceding the Maturity Date, in which case the Company shall make such delivery (and payment, if applicable) on the Maturity Date or (B) in the case of any other Settlement Method, on the second Business Day immediately following the last Trading Day of the Observation Period. If any shares of Common Stock or, in the case of Permitted Holders, Warrants are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of, as applicable, shares of Common Stock or Warrants to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation, and cash in lieu of any fractional shares of Common Stock or Warrants.

(d) A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are a multiple of $1,000 in principal amount. In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by Section  17.02(f) , with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer Tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

(e) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

108

(f) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer Tax due on the issue of, as applicable, any shares of Common Stock or Warrants upon conversion, unless the Tax is due because the Holder requests such shares or any portion of Notes not converted to be issued in a name other than the Holder’s name, in which case the Holder shall pay that Tax. The Conversion Agent shall not deliver the certificates representing or effect a book-entry transfer through the Depositary for the shares of Common Stock or Warrants being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay, or the Holder has established to the Company’s satisfaction the prior payment of, any Tax that is due by such Holder in accordance with the immediately preceding sentence.

(g) Except as provided in Section  17.04 , no adjustment shall be made for dividends on any shares of Common Stock or Warrants issued upon the conversion of any Note as provided in this Article 17 .

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below in this clause (h), and the Company shall not adjust the Conversion Rate to account for accrued and unpaid interest on the Notes. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date and before the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date or any Redemption Date shall receive the full interest payment due on the Maturity Date or such Redemption Date, as applicable, regardless of whether their Notes have been converted following such Regular Record Date.

109

(i) Each conversion shall be deemed to have been effected immediately prior to the close of business on the relevant Conversion Date; provided , however , that the Person in whose name, as applicable, the shares of Common Stock or Warrants shall be issuable upon conversion shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or as of the close of business on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion as of immediately prior to the close of business on the related Conversion Date.

(j) The Company shall not issue fractional shares or Warrants upon conversion of Notes. If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares or Warrants which shall be issuable upon conversion (and the number of fractional shares or Warrants, if any, for which cash shall be delivered) shall be computed on the basis of the aggregate Principal Amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share or Warrants would be issuable upon the conversion of any Notes, the Company shall make payment of an amount in cash in lieu of any fractional share of Common Stock or Warrants otherwise issuable upon conversion based on the Daily VWAP of the Common Stock on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected to satisfy its conversion obligation through Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional share remaining after such computation shall be paid in cash. The current market value of a fractional share shall be determined (calculated to the nearest 1/1000th of a share) by multiplying the Last Reported Sale Price of the Common Stock on the relevant Conversion Date by such fractional share and rounding the product to the nearest whole cent.

(k) Subject to this Section  17.02 , Section  17.03(b) , Section  17.07(a) and Section  17.12 , the Company may settle the Conversion Obligation in cash (“ Cash Settlement ”), shares of Common Stock (or, if applicable, Warrants), together with cash, if applicable, in lieu of delivering any fractional share of Common Stock (or, if applicable, Warrants) in accordance therewith (“ Physical Settlement ”) or a combination of cash and shares of Common Stock (or, if applicable, Warrants), together with cash, if applicable, in lieu of delivering any fractional share of Common Stock “ Combination Settlement ”), at its election, as set forth in this Section  17.02(k).

(i) All conversions for which the relevant Conversion Date occurs on or after the 25th Scheduled Trading Day prior to the Maturity Date, and all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, shall be settled using the same Settlement Method. Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to

110

the related Redemption Date or any conversions for which the relevant Conversion Date occurs on or after the 25th Scheduled Trading Day prior to the Maturity Date, the Company shall use the same Settlement Method for the Conversion Obligations for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to the Conversion Obligations for Conversions with different Conversion Dates.

(ii) If, in respect of any Conversion Date, the Company elects a Settlement Method in respect of such Conversion Date, the Company shall deliver or cause delivery of a notice (the “ Settlement Notice ”) of the relevant Settlement Method to converting Holders and the Conversion Agent (and the Trustee if not the Conversion Agent) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, if such Conversion Date occurs (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, no later than the date of issuance of such Redemption Notice or (y) on or after June 15, 2023, no later than June 15, 2023). Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the Specified Dollar Amount to be settled in cash and in shares of Common Stock (or, if applicable, Warrants), respectively. If the Company does not elect a Settlement Method for any Conversion Date prior to the deadline set forth in the second preceding sentence, the Company shall no longer have the right to elect a Settlement Method for such Conversion Date and the Company shall be deemed to have elected Combination Settlement for such Conversion Date. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. The Company shall have the right to irrevocably elect a Settlement Method and Specified Dollar Amount for all subsequent Conversion Dates by delivering the Settlement Notice to all Holders of the Notes, the Trustee and the Conversion Agent and issuing a press release containing information regarding its election of Settlement Method and Specified Dollar Amount and expressly stating such election is irrevocable and making such information available on its website. Following such an irrevocable Settlement Notice, the Company will not have the right to change the Selection Method or Specified Dollar Amount.

(iii) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “ Settlement Amount ”) shall be computed by the Company as follows:

(A) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock (or, if applicable, Warrants) equal to the Conversion Rate in effect on the Conversion Date;

111

(B) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the related Observation Period.

(iv) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(v) Notwithstanding anything to the contrary in this Indenture, if at any time prior to the Share Increase Approval (as defined in the Note Purchase Agreement and referred to in Section  17.08(a) ), Additional Shares are issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change, the Company shall settle its Conversion Obligation with respect to such Additional Shares by Cash Settlement, to the extent that the Company does not then have a sufficient number of shares authorized and reserved for issuance upon conversion of Notes under the Company’s Governing Documents to issue all shares of Common Stock (including any Additional Shares) that may be issuable upon conversion of all Notes then outstanding.

Section 17.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.

(a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “ Additional Shares ”), as described below. A conversion of Notes shall be deemed for these purposes

112

to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “ Make-Whole Fundamental Change Period ”).

(b) If, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table set forth in Section  17.03(e) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(d) The Stock Prices set forth in the column headings of the table set forth in Section  17.03(e) below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table set forth in Section  17.03(e) below shall be adjusted in the same manner and at the same time as the Conversion Rate is adjusted as set forth in Section  17.04 .

113

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section  17.03 for each Stock Price and Effective Date set forth below:

114

The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in such table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $25.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $4.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no further Additional Shares shall be added to the Conversion Rate.

(f) Nothing in this Section  17.03 shall prevent an adjustment to the Conversion Rate pursuant to Section  17.04 in respect of a Make-Whole Fundamental Change.

Section 17.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section  17.04 , without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder .

(a) If the Company issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Company effects a share split or share combination of the Common Stock, the Conversion Rate shall be adjusted based on the following formula:

115

where,

CR ₀ = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

CR’ = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;

OS ₀ = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and

OS’ = the number of shares of Common Stock outstanding immediately after, and solely as a result of, giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this Section  17.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section  17.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Applicable Rate will be made (other than (i) as a result of a reverse share split or share combination or (ii) with respect to the Company’s right to readjust the Conversion Rate as described in the immediately preceding sentence).

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

where,

CR ₀ = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;

116

CR’ = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

OS ₀ = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;

X = the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase in the Conversion Rate made under this Section  17.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased, effective as of such date of expiration, to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased, effective as of the date of the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the two immediately preceding sentences).

In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section  17.04(a) or Section  17.04(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section  17.04(d) shall apply, and (iii) Spin-Offs as to which the provisions set forth below in this Section  17.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “ Distributed Property ”), then the Conversion Rate shall be increased based on the following formula:

117

where,

CR ₀ = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR’ = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

SP ₀ = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV = the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

Any increase made under the portion of this Section  17.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the Board of Directors announces its decision not to make or pay such distribution, to the Conversion Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “ FMV ” (as defined above) is equal to or greater than “ SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “ FMV ” (as defined above) of any distribution for purposes of this Section  17.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the average of Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the second sentence of this paragraph).

With respect to an adjustment pursuant to this Section  17.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “ Spin-Off ”), the Conversion Rate shall be increased based on the following formula:

118

where,

CR ₀ = the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR’ = the Conversion Rate in effect immediately after the end of the Valuation Period;

FMV ₀ = the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section  1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “ Valuation Period ”); and

MP ₀ = the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase to the Conversion Rate under the preceding paragraph shall become effective immediately after the open of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references in the preceding paragraph to a “ 10 consecutive Trading Day period ” shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, the Conversion Date in determining the Conversion Rate and the effective time of any adjustment thereto and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references in the preceding paragraph with respect to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, such Trading Day in determining the conversion rate as of such Trading Day.

For purposes of this Section  17.04(c) (and subject in all respect to Section  17.11 ), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section  17.04(c) (and no adjustment to the Conversion Rate under this Section  17.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options

119

or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section  17.04(c) . If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other such event (of the type described in the immediately preceding sentence) with respect thereto that was deemed to effect a distribution of rights, options or warrants, in each case for which an adjustment to the Conversion Rate under this Section  17.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted, effective as of the date of such final redemption or purchase, to give effect to such distribution, deemed distribution or Trigger Event or other such event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted, effective as of such expiration or termination date, as if such rights, options and warrants had not been issued.

For purposes of Section  17.04(a) , Section  17.04(b) and this Section  17.04(c) , if any dividend or distribution to which this Section  17.04(c) is applicable (other than a Spin-Off) has the same Record Date as one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section  17.04(a) is applicable (the “ Clause A Distribution ”); or

(B) a dividend or distribution of rights, options or warrants to which Section  17.04(b) is applicable (the “ Clause B Distribution ”),

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section  17.04(c) is applicable (the “ Clause C Distribution ”) and any Conversion Rate adjustment required by this Section  17.04(c) with respect to such Clause C Distribution shall first be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section  17.04(a) and Section  17.04(b) with respect thereto shall then be made (as if the Conversion Rate adjustment required by this Section  17.04(c) with respect to such Clause C Distribution had been made immediately prior to the open of business on the Ex-Dividend Date for the Clause A Distribution and the Clause B Distribution), except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-

120

Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section  17.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section  17.04(b) .

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be increased based on the following formula:

where,

CR ₀ = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

CR’ = the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP ₀ = the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C = the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

Any increase in the Conversion Rate pursuant to this Section  17.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “ SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the second sentence of this paragraph).

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock (other than an odd-lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

121

where,

CR ₀ = the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

CR’ = the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

AC = the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS ₀ = the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

OS’ = the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP’ = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

The increase to the Conversion Rate under this Section  17.04(e) shall become effective at the open of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section  17.04(e) with respect to “10” or “10th” shall be deemed replaced with such lesser number of Trading Days as have elapsed during the period from, and including, the Trading Day after the expiration date of such tender or exchange offer to, but excluding, such Trading Day in determining the Conversion Rate as of such Trading Day and (y) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section  17.04(e) with respect to “10” or “10th”

122

shall be deemed replaced with such lesser number of Trading Days as have elapsed during the period from, and including, the Trading Day after the date that such tender or exchange offer expires and to, but excluding, the Conversion Date in determining the Conversion Rate and the effective time of any adjustment thereto.

If the Company or any 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 ultimately prevented by Applicable Law from effecting all or any portion of such purchases or all such purchases are rescinded, the Conversion Rate shall immediately be readjusted, effective as of the date of the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that had been effected. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the immediately preceding sentence).

(f) Notwithstanding this Section  17.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and either (i) a Holder has converted its Notes for Physical Settlement on a Conversion Date that is on or after such Ex-Dividend Date and on or prior to the related Record Date and such Holder would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section  17.02(i) based on an adjusted Conversion Rate otherwise becoming effective on such Ex-Dividend Date or (ii) a Holder has converted its notes for Combination Settlement with the last Trading Day of the related Observation Period ending on or after such Ex-Dividend Date and on or prior to the related Record Date and such Holder would be treated as the record holder of the shares of Common Stock as of the last trading day of such Observation Period as described in Section  17.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, in the case of (i) or (ii), notwithstanding the Conversion Rate adjustment provisions in this Section  17.04, the Conversion Rate adjustment otherwise becoming effective on such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance or acquisition of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities.

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section  17.04 , and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted

123

by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income Tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) Notwithstanding anything to the contrary in this Article 17 , the Conversion Rate shall not be adjusted:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv) upon the repurchase of any shares of Common Stock pursuant to an odd lot tender offer or an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the nature described in Section  17.04(e) ;

(v) solely for a change in the par value of the Common Stock; and

(vi) for accrued and unpaid interest, if any.

(j) All calculations and other determinations under this Article 17 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion

124

Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section  17.04 , the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(m) For purposes solely of this Section  17.04 , the number of shares of Common Stock which the Holder of any Note would have been entitled to receive had such Note been converted in full at any time or into which any Note was converted at any time shall be determined assuming such Note was convertible in full at such time, although such Note may not be convertible in full at such time pursuant to Section  17.12 .

(n) Irrespective of any adjustment in the Conversion Rate applicable or the amount or kind of shares into which the Notes are convertible, Notes theretofore or thereafter issued may continue to express the same Conversion Rate initially applicable or amount or kind of shares initially issuable upon conversion of the Notes pursuant to this Indenture.

Section 17.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period, a Valuation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each that it determines to be appropriate to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate (or changes to the market price per share of Common Stock resulting from any such event) where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated, without duplication of any adjustment made pursuant to Section  17.04 . The Company will likewise make appropriate adjustments where a Conversion Rate adjustment otherwise required to be made pursuant to the provisions of Sections 17.04(a) through 17.04(e) is not made in accordance with the provisions described under Section  17.04 that permit or require participation by Holders in a transaction in lieu of such Conversion Rate adjustment.

Section 17.06. Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are surrendered for conversion (assuming delivery of the maximum number of Additional Shares pursuant to Section  17.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

125

Section 17.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a share split or share combination),

(ii) any consolidation, merger, combination or similar transaction involving the Company,

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “ Merger Event ”), then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “ Reference Property ,” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock would have owned or been entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section  13.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided , however , that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section  17.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section  17.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section  17.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have owned or been entitled to receive upon such Merger Event and (III) the Daily VWAP will be calculated based on the value of the amount and kind of Reference Property that a holder of one share of Common Stock would have owned or been entitled to receive upon such Merger Event.

126

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. If the holders of the Common Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section  17.03 ), multiplied by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 17 . If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, 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 Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 18 .

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section  17.07 , the Company shall promptly file with the Trustee, and the Conversion Agent (if other than the Trustee) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section  17.07 . None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section  17.01 and Section  17.02 prior to the effective time of such Merger Event.

127

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

(e) Notwithstanding the Conversion Rate adjustment provisions described in Section  17.04(a) through 17.04(e) , no adjustment to the Conversion Rate shall be made pursuant to such provisions in the event of any dividend, distribution, share split, share combination or issuance upon a Merger Event to which the provisions under this Section  17.07 apply.

Section 17.08. Certain Covenants.

(a) The Company covenants that it shall (i) at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock or shares held in treasury, for the purpose of effecting the conversion of Notes, the full number of shares of Common Stock then issuable upon the conversion of all Notes then outstanding (other than Additional Shares that may be issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change), and (ii) at all times after the Share Increase Approval (as defined in the Note Purchase Agreement), if obtained, reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock or shares held in treasury, for the purpose of effecting the conversion of Notes, the full number of shares of Common Stock then issuable upon the conversion of all Notes then outstanding (including Additional Shares that may be issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change).

(b) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be duly authorized, fully paid and non-assessable by the Company and free from all Taxes, liens and charges with respect to the issue thereof.

(c) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the SEC, secure such registration or approval, as the case may be.

(d) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes.

Section 17.09. Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any

128

supplemental indenture provided to be employed, in making the same. The Trustee and any Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 17 . Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section  17.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section  17.07 or to any adjustment to be made with respect thereto, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee and the Conversion Agent (if other than the Trustee) prior to the execution of any such supplemental indenture in addition to any other deliverables required hereunder in connection with the execution of such supplemental indenture) with respect thereto .

Section 17.10. Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section  17.04 ;

(b) Merger Event; or

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

129

Section 17.11. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property, subject to readjustment in the event of the expiration, termination or redemption of such rights, all as provided in the penultimate paragraph of Section  17.04(c).

Section 17.12. Ownership Limitations.

(a) Notwithstanding any other provision of this Indenture, except in the context of a Fundamental Change, during any period of time in which a Person’s Beneficial Ownership of shares of Common Stock is less than 10%, and such Person is not otherwise an Affiliate of the Company, and for so long as the Common Stock is registered under the Exchange Act, such Person shall not have the right to convert all or any portion of any of its Notes into shares of Common Stock to the extent that, upon and after giving effect to such conversion, such Person (together with such Person’s Affiliates and any other Persons or entities whose Beneficial Ownership of shares of Common Stock would be aggregated with such Person’s for purposes of Section 13(d) of the Exchange Act (the “ Affiliated Parties ”) (including shares of Common Stock held by any “group” of which such Person or any of its Affiliated Parties is a member)) would have Beneficial Ownership of more than 9.99% of the total number of shares of Common Stock then issued and outstanding. The Company shall not adopt any shareholder rights plan or take any other action that would have the effect of restricting or adversely affecting a Person’s election to change such foregoing percentage limitation. If at any time the Company shall be required under the Note Purchase Agreement or pursuant to the Indenture to issue shares of Common Stock to the Permitted Holders, but the issuance of such shares of Common Stock would to the knowledge of the Company exceed the ownership limitations set forth in this Section  17.12(a) , in lieu of issuing such number of shares of Common Stock to the Permitted Holders in excess of the ownership limitations set forth in this Section  17.12(a) , the Company shall issue to the Permitted Holders a Warrant to acquire such shares of Common Stock pursuant to the Purchase Agreement.

(b) For purposes of this Section  17.12 , “ Beneficial Ownership ” means the number of shares of Common Stock beneficially owned by a Person and its Affiliated Parties (and any other Persons or entities acting as a “group” together with a Person or any of such Holder’s Affiliated Parties) and shall include the number of shares of Common Stock issuable upon conversion of the Notes with respect to which such determination is being made, but shall exclude the number of shares of Common Stock that would be issuable upon (i) conversion of the remaining, unconverted portion of the Notes beneficially owned by such Person or any of its Affiliated Parties (and any other Persons or entities acting as a “group” together with such Person or any of such Person’s

130

Affiliated Parties) and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company exercisable for or convertible into Common Stock that are subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Person or any of its Affiliated Parties (and any other Persons or entities acting as a “group” together with such Person or any of such Person’s Affiliated Parties). Except as set forth in the preceding sentence, for purposes of Section  17.12(a), Beneficial Ownership shall be calculated (and, for such purpose, whether any Person or entity forms a “group” with any Person or such Person’s Affiliated Parties will be determined) in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher Beneficial Ownership for any such party, then such Beneficial Ownership will be calculated in accordance with Section 16 of the Exchange Act and the rules and regulations thereunder), it being acknowledged by each Person that the Company is not representing to any Person that such calculation is in compliance with Section 13(d) of the Exchange Act and each Person is solely responsible for any schedules required to be filed in accordance therewith. To the extent that an ownership limitation contained in Section  17.12(a) applies, the determination of whether the Notes owned by a Person are convertible (in relation to other securities owned by such Person together with its Affiliated Parties (and any other Persons or entities acting as a “group” together with such Person or any of such Person’s Affiliated Parties)) and of which portion of the Notes owned by such Person is convertible shall be in the sole discretion of such Person, and the submission of a conversion notice to the Conversion Agent (pursuant to Section  17.02 ) shall be deemed to be such Person’s determination of whether the Notes owned by such Person are convertible (in relation to other securities owned by such Person together with any of its Affiliated Parties (and any other Persons or entities acting as a “group” together with such Person or any of such Person’s Affiliated Parties)) and of which portion of such Notes are convertible, in each case subject to the then applicable ownership limitation (as determined in accordance with Section  17.12(a)), and neither the Company nor the Conversion Agent shall have any obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any “group” status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To ensure compliance with this restriction, the Person will be deemed to represent to the Company each time it delivers a conversion notice (pursuant to Section  17.02 ) that such conversion notice has not violated the restrictions set forth in Section  17.12(a) .

(c) For the avoidance of doubt, if a Person purports to convert any of its Notes into shares of Common Stock hereunder and any delivery otherwise owed to such Person hereunder is not made, in whole or in part, as a result of the then applicable ownership limitation (as determined in accordance with Section  17.12 ), then the Person’s rights under the Notes and this Indenture pursuant to which such delivery was not made will not be extinguished and instead such Notes will be deemed to have never been converted by such Person and will remain outstanding under this Indenture.

131

Section 17.13. No Voting or Dividend Rights . Except as may be specifically provided for herein, until the conversion record date in respect of the conversion of such Note:

(a) no Holder of such Note shall have or exercise any rights by virtue hereof as a holder of shares of Common Stock, including, without limitation, the right to vote, to receive dividends and other· distributions as a holder of shares of Common Stock or to receive notice of, or attend, meetings or any other proceedings of the holders of shares of Common Stock;

(b) the consent of any such Holder as a holder of shares of Common Stock shall not be required with respect to any action or proceeding of the Company;

(c) no such Holder, by reason of the ownership or possession of such Note, shall have any right to receive any cash dividends, stock dividends, allotments or rights or other distributions paid, allotted or distributed or distributable to the holders of shares of Common Stock prior to, or for which the relevant record date preceded, the conversion record date in respect of the conversion of such Note; and

(d) no such Holder shall have any right not expressly conferred hereunder or by applicable law with respect to such Note held by such Holder.

For purposes of this Section  17.13 , “conversion record date” means, in respect of the conversion of any Note, the date specified in Section  17.02(i) upon which the Person in whose name shares of Common Stock are issuable upon conversion of such Note shall be treated as the holder of record of such shares of Common Stock upon the conversion of such Note.

ARTICLE 18

Repurchase of Notes at Option of Holders

Section 18.01. Repurchase at Option of Holders Upon a Fundamental Change. If a Fundamental Change occurs at any time, each Holder of Notes outstanding on the Fundamental Change Repurchase Date shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the “ Fundamental Change Repurchase Date ”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “ Fundamental Change Repurchase Price ”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 18 .

(a) Repurchases of Notes under this Section  18.01 shall be made, at the option of the Holder thereof, upon:

132

(i) delivery to the Trustee by a Holder of a duly completed notice (the “ Fundamental Change Repurchase Notice ”) in the form attached to the Form of Note attached hereto as Exhibit A , if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Trustee at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Trustee, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:

(A) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(B) in the case of Global Notes, the CUSIP identifying the Notes to be delivered for repurchase;

(C) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

(D) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided , however , that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee the Fundamental Change Repurchase Notice contemplated by this Section  18.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Trustee in accordance with Section  18.02 .

The Trustee shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

(b) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “ Fundamental Change Company Notice ”) of the occurrence of the

133

effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 18 ;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(vii) if applicable, the Conversion Rate then in effect;

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section  18.01.

At the Company’s request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided , however , that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company and delivered to the Trustee at least three (3) Business Days before such Fundamental Change Company Notice is required to be sent to the Holders pursuant to this Section  18.01 (unless a shorter notice period is agreed to by the Trustee), together with an Officers’ Certificate requesting that the Trustee give such Fundamental Change Company Notice and the Trustee shall not be obligated to publish any notice in any newspaper or similar media.

134

(c) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Trustee will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 18.02. Withdrawal of Fundamental Change Repurchase Notice.

(a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Trustee in accordance with this Section  18.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted,

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted,

(iii) the CUSIP for Global Notes in respect of which such notice of withdrawal is being submitted, and

(iv) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided , however , that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary.

Section 18.03. Deposit of Fundamental Change Repurchase Price.

(a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section  4.03) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day

135

immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date ( provided the Holder has satisfied the conditions in Section  18.01 ) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section  18.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided , however , that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid interest).

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section  18.01 , the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

(d) Covenant to Comply with Applicable Laws Upon Repurchase of Notes . In connection with any repurchase offer, the Company will, if required:

(e) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act;

(f) file a Schedule TO or any other required schedule under the Exchange Act; and

(g) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 18 to be exercised in the time and in the manner specified in this Article 18 .

136

ARTICLE 19

Repurchase And Redemption

If the aggregate purchase price of the Notes tendered in connection with any Excess Proceeds Offer exceeds the Excess Proceeds Offer Amount (less the fees described in clause (A) above), the Notes will be purchased on a pro rata basis except any Notes represented by a Global Note will be selected for purchase by such method as The Depository Trust Company or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection unless otherwise required by law, but in minimum denominations of $1,000 principal amount and integral multiples thereof. If the aggregate purchase price of the Notes tendered in connection with any Excess Proceeds Offer is less than the Excess Proceeds Offer Amount (less the fees described in clause (A) above), the Company shall be permitted to use the portion of the Excess Proceeds Offer Amount that is not required to be applied to the purchase of Notes in connection with such Excess Proceeds Offer for any purpose not prohibited hereunder.

(f) In connection with any repurchase of the Notes pursuant to this Section  19.05, the Company shall: (i) comply with the provisions of Rule 13e-4, Rule 14e-1 (or any successor provision) and any other tender offer rules under the Exchange Act that may then be applicable and (ii) otherwise comply with all federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section  19.05 , the Company’s compliance with such laws and regulations shall not in and of itself cause a breach of its obligations under this Section  19.05 .

141

(g) For the avoidance of doubt, any written offer to repurchase the Notes delivered to Holders in accordance with this Section  19.05 shall not impair the right of such Holders to convert the Notes pursuant to the terms of this Indenture prior to the repurchase thereof.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price of (if applicable), accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money and/or shares of Common Stock, as the case may be, herein prescribed.

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

Subject to certain limitations, the Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture.

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or any portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

In addition to the rights provided to Holders of Notes under the Indenture, Holders shall have all the rights set forth in the Registration Rights Agreement dated as of September 26, 2018, among the Company and the Holders.
